Genetic polymorphisms in the metabolic pathway and non-Hodgkin lymphoma survival,

AMERICAN JOURNAL OF HEMATOLOGY, Issue 1 2010
Xuesong Han
Metabolic pathway enzymes, such as Cytochrome P450 (CYP), glutathione S-transferase (GST), and N -acetyltransferases (NAT) are involved in activation and detoxification of environmental carcinogens as well as drug metabolism. We hypothesized that the genetic variations in such metabolic pathways may affect NHL prognosis and survival. Follow-up information of 496 female NHL incident cases diagnosed during 1996,2000 in Connecticut were abstracted from the Connecticut Tumor Registry in 2008; survival analyses were conducted by comparing the Kaplan-Meier curves, and hazard ratios (HR) were computed from the Cox Proportional Hazard models adjusting for demographic and tumor characteristics which were suggested by previous studies to be determinants of NHL survival. We identified six SNPs from four metabolism genes (CYP2E1, GSTP1, GSTT1, and NAT1) that were associated with NHL survival. Specifically, polymorphisms in GSTT1 were associated with follicular lymphoma survival; and polymorphisms in CYP2E1, GSTP1, and NAT1 were associated with survival of chronic lymphocytic leukemia/small lymphocytic lymphoma. Our study suggests that genetic polymorphisms in metabolic pathways may help improve the prediction of NHL survival and prognosis. Am. J. Hematol., 2010. © 2009 Wiley-Liss, Inc. [source]


Biology, clinical characteristics, and management of adrenocortical tumors in children

PEDIATRIC BLOOD & CANCER, Issue 3 2005
Carlos Rodriguez-Galindo MD
Abstract Childhood adrenocortical tumors (ACT) are very aggressive endocrine neoplasms whose incidence is quite low. Little is known about their pathogenesis, clinical presentation, and optimal treatment. In recent years, however, new information has been derived from the International Pediatric Adrenocortical Tumor Registry (IPACTR), and new clues to its pathogenesis have emerged. To provide an overview of the available data that may apply to pediatric ACT, we reviewed the epidemiology, pathogenesis, and treatment of ACT in adults and in children. Germline TP53 mutation is almost always the predisposing factor in childhood ACT. A unique germline mutation (TP53,R337H) has been described in Southern Brazil, where the incidence of ACT is 10,15 times the general incidence. Childhood ACT typically present during the first 5 years of life and has female predominance. Hormone hyperproduction is almost universal, and most patients present with virilization. Two-thirds of patients have resectable tumors. Surgery is the definitive treatment for ACT, and a curative complete resection should always be attempted. Cisplatin-based chemotherapy with mitotane is indicated for unresectable or metastatic disease, although its impact on overall outcome is slight. In childhood ACT, age, tumor size, and tumor resectability are the most important prognostic indicators. Outcome is stage-dependent; patients with small, resectable tumors have survival rates in excess of 80%, whereas the outcome for patients with unresectable disease is dismal. Patients with large, resectable tumors have an intermediate outcome. Childhood ACT are rare, but their unique epidemiology appear to implicate novel oncogenic pathways that are unique to the pediatric population. Multi-institutional and prospective studies are necessary to further our understanding of the pathogenesis and to improve outcomes. © 2005 Wiley-Liss, Inc. [source]


Ethnic differences in quality of life among early breast and prostate cancer survivors

PSYCHO-ONCOLOGY, Issue 2 2002
Carolyn Cook Gotay
This study assessed quality of life (QOL) in recently diagnosed breast and prostate cancer patients of European American and Asian Pacific Islanders (specifically, individuals of Filipino, Japanese, and Native Hawaiian ancestry) to investigate whether QOL varied according to ethnicity and the relative importance of ethnicity as a predictor of QOL. Participants were identified through consecutive registrations on the Hawaii Tumor Registry, based on a diagnosis of breast or prostate cancer 4,6 months previously. QOL was measured by the QLQ-C30, a standardized questionnaire widely used in cancer patient populations. Two hundred and twenty-seven individuals participated (101 prostate and 126 breast cancer patients). QOL was similar across ethnic groups in most areas of QOL. However, differences were found in several areas, all in the direction of Filipino patients reporting worse outcomes. Hierarchical stepwise regressions supported the importance of ethnicity, controlling for clinical and demographic predictors. We conclude that additional research is needed to understand the relationship between ethnicity and QOL in cancer survivors. Copyright © 2002 John Wiley & Sons, Ltd. [source]


Synovial Cell Sarcoma: Diagnosis, Treatment, and Outcomes

THE LARYNGOSCOPE, Issue 11 2002
Swapna S. Kartha
Abstract Objectives/Hypothesis Synovial cell sarcoma is a mesenchymal tumor predominantly of the lower extremities. Three percent of cases arise in the head and neck region. It is thought that head and neck synovial sarcoma has a better prognosis than tumors of the extremities. Our experience has demonstrated aggressive behavior of this neoplasm in the head and neck. This compelled us to compare our experience with other studies. Study Design Retrospective chart review. Methods We obtained the records of patients diagnosed with head and neck synovial sarcoma from the Tumor Registry of the University of Louisville School of Medicine (Louisville, KY) and affiliated hospitals for data compiled between January 1990 and December 2000. Data on patient demographics, clinical findings and symptoms, histological findings, treatment, extent of disease, recurrence, and survival were recorded. The literature was reviewed identifying reports of synovial cell sarcoma. Results Five consecutive patients with synovial cell sarcoma were assessed at our facility. The median patient age was 28.2 years. All of the patients underwent an aggressive primary surgical excision followed by irradiation. All patients received chemotherapy after recurrence. Four of the five patients had local recurrence, and all five of the patients developed distant metastases. Three of the patients have died, and two are alive with evidence of disease. Novel sites are reported including the ethmoid sinus and the parotid gland. This group demonstrated a 40% 5-year overall survival, which was lower than the 60% 5-year survival reported in the literature for all sites. Conclusions Synovial cell sarcoma of the head and neck is a disease of young people and carries a poor prognosis. The aggressive nature of the disease may require modification of accepted treatment modalities and sequence. [source]


Recruiting and retaining breast cancer survivors into a randomized controlled exercise trial,

CANCER, Issue S11 2008
Survivorship Study, The Yale Exercise
Abstract BACKGROUND. Given observational findings that physical activity reduces breast cancer risk, improves survival, and improves quality of life in breast cancer survivors, a need has been identified for randomized controlled trials that testthe efficacy of exercise on biological mechanisms associated with breast cancer survival. The primary aims of the Yale Exercise and Survivorship Study were to 1) determine the feasibility of recruiting breast cancer survivors into a randomized controlled trial of the effects of exercise on biological markers and/or mechanisms associated with survival, 2) compare the effectiveness of various recruitment strategies on accrual rates and baseline characteristics, and 3) report adherence to the exercise trial. METHODS. Seventy-five postmenopausal breast cancer survivors self-referred into the trial or were recruited through the Connecticut Tumor Registry and randomly assigned to an exercise (n = 37) or usual-care (n = 38) group. The exercise group participated in 150 min/wk of supervised gym-based and home-based aerobic exercise for 6 months. The usual-care group was instructed to maintain current physical activity level. RESULTS. A total of 75 women (an accrual rate of 9.5%) were randomized to the trial. Rates of accrual were higher for women who self-referred into the study (19.8%) compared with women recruited via the cancer registry (7.6%); however, demographic, physiologic, and prognostic characteristics did not differ between the 2 recruitment strategies. On average, exercisers increased moderate- intensity to vigorous-intensity aerobic exercise by 129 minutes per week compared with 44 minutes per week among usual-care participants (P < .001). Women in the exercise-intervention group increased their average pedometer steps by 1621 steps per day compared with a decrease of 60 steps per day among women in the usual-care group (P < .01). CONCLUSIONS. Findings from this study will provide useful information for investigators who are conducting exercise trials in cancer populations, clinicians who are treating women diagnosed with breast cancer, and exercise professionals who are developing community-based exercise programs for cancer survivors.

Cross-sectional and longitudinal comparisons of health-related quality of life between patients with prostate carcinoma and matched controls,,§

CANCER, Issue 9 2004
M.P.H., Richard M. Hoffman M.D.
Abstract BACKGROUND Prostate carcinoma and treatments affect health-related quality of life (HRQOL). The authors prospectively compared prostate and general HRQOL between prostate carcinoma cases and an age-matched and ethnicity-matched control group. METHODS The case cohort consisted of 293 men with localized prostate carcinoma who were selected randomly from the population-based New Mexico Tumor Registry, and the control cohort consisted of 618 men who were selected randomly from administrative databases and matched for age and ethnicity. Subjects completed a baseline survey of demographics, socioeconomic status, comorbidity, and prostate and general HRQOL. Also, 210 cases (71.7%) and 421 controls (67.8%) completed a follow-up survey 5 years later. Multinomial logistic regression models compared baseline characteristics as well as 5-year general HRQOL outcomes measured by selected domains of the Medical Outcomes Study SF-36. The authors used a mixed-model repeated-measures analysis of variance and multinomial regression analyses to compare longitudinal changes in urinary, bowel, and sexual function between groups. RESULTS At baseline, patients with prostate carcinoma had better urinary control and sexual function than controls. Over 5 years, sexual function declined significantly among controls, although urinary function remained stable. However, patients with cancer subsequently reported significant declines in both domains and were left with much worse function and more bother than controls. Bowel function and general HRQOL were similar for both groups at follow-up. CONCLUSIONS Prostate carcinoma treatment led to significant 5-year declines in urinary and sexual function that far exceeded age-related changes in controls. Patients with cancer had significantly worse function and more bother than controls for these disease-specific domains of HRQOL. Bowel function and general HRQOL were not affected by cancer status.

The relevance of occult axillary micrometastasis in ductal carcinoma in situ,

CANCER, Issue 10 2003
A clinicopathologic study with long-term follow-up
Abstract BACKGROUND Ductal carcinoma in situ (DCIS) represents 20% of newly diagnosed breast carcinoma cases. Historically, the incidence of axillary metastasis in DCIS has been small (1,2%) and its significance has been debated. It is widely known that serial sections of lymph nodes coupled with keratin immunohistochemistry (IHC) increases identification of micrometastasis. The advent of sentinel lymph node evaluation underscores the need to reevaluate the significance of occult micrometastases in DCIS. METHODS Patients with DCIS and negative axillary lymph nodes from 1974 to 1992 were selected from the Saint Barnabas Medical Center Tumor Registry. All diagnoses were confirmed, and paraffin blocks were retrieved after acceptance into the study. Seven serial sections were obtained from each block and evaluated with two cytokeratin IHC stains. Clinical follow-up ranged from 10 to 28 years. RESULTS One hundred two patients were included in the study. Micrometastases were identified in 13 patients (13%), mostly on 1 level and composed of microscopic clusters in the subcapsular sinus. Seven of these lymph node,positive patients (58%) had high-grade comedo DCIS, 4 (33%) had intermediate grades of various types of DCIS, and one had a low-grade micropapillary DCIS. The overall disease recurrence rate was 12%, but micrometasis was not detected in any of the patients who developed disease recurrence. CONCLUSIONS Serial IHC evaluation of lymph nodes dramatically increased the identification of occult micrometastasis. However, IHC detected micrometastasis has no apparent clinical significance in DCIS, based on the current long-term clinicopathologic study. Therefore, the authors questioned the significance of occult micrometastasis, identified by IHC, in DCIS of any type and extent. Further evaluation and follow-up of lymph node micrometastases in patients with invasive tumors of various sizes are needed. The current findings would not support altering the stage of patients with DCIS and micrometastasis detected by IHC only. Cancer 2003. © 2003 American Cancer Society. [source]


Breast Cancer Incidence in a Cohort of Women with Benign Breast Disease from a Multiethnic, Primary Health Care Population

THE BREAST JOURNAL, Issue 2 2007
Maria J. Worsham PhD
Abstract:, Women with benign breast diseases (BBD), particularly those with lesions classified as proliferative, have previously been reported to be at increased risk for subsequent development of breast cancer (BC). A cohort of 4970 women with biopsy-proven BBD, identified after histopathology review of BBD biopsies, was studied for determination of subsequent development of BC. We report on 4537 eligible women, 28% of whom are African-American, whose BBD mass was evaluable for pathologic assessment of breast tissue. Ascertainment of subsequent progression to BC from BBD was accomplished through examination of the tumor registries of the Henry Ford Health system, the Detroit SEER registry, and the State of Michigan cancer registry. Incidence rates (IR) are reported per 100,000 person years at risk (100 k pyr). Poisson regression models were used to evaluate the association of demographic and lesion characteristics with BC incidence, using person years at the time of BBD diagnosis as the offset variable. The estimated overall BC IR for this cohort is 452 (95% confidence interval [CI] = 394,519) per 100 k pyr. Incidence for women age 50 and older is 80% greater than for younger women (p = 0.007, IRR = 1.8, 95% CI = 1.36,2.36). Neither marital status (p = 0.91, IRR = 0.97, 95% CI = 0.73,1.29) nor race (p = 0.67, IRR = 0.9, 95% CI = 0.54,1.48) is associated with differences in BC IR. Compared with women having nonproliferative lesions, the risk for BC is greater for women with atypical ductal hyperplasia of (IRR = 5.0; 95%CI = 2.26,11.0; p < 0.001) and other proliferative lesions (IR = 1.7, 95% CI = 1.02,2.95; p = 0.04). BC risk for woman with atypical lesions is significantly higher than for women with proliferative lesions without atypia (IRR = 2.58, 95% CI = 1.35,4.90; p = 0.0039). Neither race nor marital status was a factor for BC incidence from BBD in this cohort. Age retained its importance as a predictor of risk. BBD lesion histopathology in the outcome categories of either proliferative without atypia or proliferative with atypia are significant risk factors for BC, even when adjusted for the influence of demographic characteristics. The risks associated with BBD histological classifications were not different across races. [source]


Microvessel Density in Head and Neck Squamous Cell Carcinoma Primary Tumors and Its Correlation with Clinical Staging Parameters

THE LARYNGOSCOPE, Issue 3 2006
Eric J. Lentsch MD
Abstract Objective: Our objective was to assess angiogenesis in head and neck squamous cell primary tumors and measure its correlation with tumor site and clinical and pathologic staging parameters. Study Design: Patients from the tumor registries of the University of Louisville and affiliated hospitals who had biopsy-proven head and neck squamous cell carcinoma were retrospectively assessed over a 5-year period (1995,2000). Methods: Patient records were reviewed for tumor site, TNM staging, surgical treatment, and tumor pathologic staging data. Cell blocks were obtained for each of the study patients, and CD31 staining was used to measure microvessel density (MVD) in areas of primary tumor hot spots. Results: Twenty-eight consecutive patients met inclusion criteria and had adequate cell blocks for evaluation. MVD for T3 staged (41.2 MVD, mean) and T4 staged (36.4 MVD, mean) tumors were higher than earlier staged T1 staged (31.3 MVD, mean) and T2 staged (24.9 MVD, mean) tumors. Laryngeal T3 and T4 tumors had MVDs as high as 43.4 MVD (mean) and 40.4 MVD (mean), respectively, compared with a 23.9 MVD for T2 tumors. This difference was statistically significant (P < .01). Our report indicates a trend toward increasing MVD with N-stage. Conclusion: Our series demonstrates that there is a strong correlation between MVD in primary tumor hot spots and tumor T-stage, which implies that tumor angiogenesis may be a factor in tumor progression.

Racial differences in tumor stage and survival for colorectal cancer in an insured population,

CANCER, Issue 3 2007
Chyke A. Doubeni MD
Abstract BACKGROUND. Despite declining death rates from colorectal cancer (CRC), racial disparities have continued to increase. In this study, the authors examined disparities in a racially diverse group of insured patients. METHODS. This study was conducted among patients who were diagnosed with CRC from 1993 to 1998, when they were enrolled in integrated healthcare systems. Patients were identified from tumor registries and were linked to information in administrative databases. The sample was restricted to non-Hispanic whites (n = 10,585), non-Hispanic blacks (n = 1479), Hispanics (n = 985), and Asians/Pacific Islanders (n = 909). Differences in tumor stage and survival were analyzed by using polytomous and Cox regression models, respectively. RESULTS. In multivariable regression analyses, blacks were more likely than whites to have distant or unstaged tumors. In Cox models that were adjusted for nonmutable factors, blacks had a higher risk of death from CRC (hazard ratio [HR], 1.17; 95% confidence interval [95% CI], 1.06,1.30). Hispanics had a risk of death similar to whites (HR, 1.04; 95% CI, 0.92,1.18), whereas Asians/Pacific Islanders had a lower risk of death from CRC (HR, 0.89; 95% CI, 0.78,1.02). Adjustment for tumor stage decreased the HR to 1.11 for blacks, and the addition of receipt of surgical therapy to the model decreased the HR further to 1.06. The HR among Hispanics and Asians/Pacific Islanders was stable to adjustment for tumor stage and surgical therapy. CONCLUSIONS. The relation between race and survival from CRC was complex and appeared to be related to differences in tumor stage and therapy received, even in insured populations. Targeted interventions to improve the use of effective screening and treatment among vulnerable populations may be needed to eliminate disparities in CRC.

Adenoid cystic carcinoma: A retrospective clinical review

INTERNATIONAL JOURNAL OF CANCER, Issue 3 2001
Atif J. Khan M.D.
Abstract Adenoid cystic carcinoma (ACC) are uncommon tumors, representing about 10% to 15% of head and neck tumors. We compare the survival and control rates at our institution with those reported in the literature, and examine putative predictors of outcome. All patients registered with the tumor registry as having had ACC were identified. Demographic and survival variables were retrieved from the database. Additionally, a chart review of all patients was done to obtain specific information. Minor gland tumors were staged using the American Joint Committee on Cancer's criteria for squamous cell carcinomas in identical sites. Histopathologic variables retrieved included grade of the tumor, margins, and perineural invasion. Treatment modalities, field sizes, and radiation doses were recorded in applicable cases. An effort to retrieve archival tumor specimens for immunohistochemical analysis was undertaken. A total of 69 patients were treated for ACC from 1955 to 1999. One patient, who presented with fatal brain metastasis, was excluded from further analysis. Of the remaining 68 patients, 30 were men and 38 were women. The average age at diagnosis was 52 years, and mean follow-up was 13.2 years. Mean survival was 7.7 years. Overall survival (OS) rates at 5, 10, and 15 years were 72%, 44%, and 34%, and cause-specific survival was 83%, 71%, and 55%, respectively. Recurrence-free survival rates were 65%, 52%, and 30% at 5, 10, and 15 years, with a total of 29 of 68 (43%) eventually suffering a recurrence. Overall survival was adversely affected by advancing T and AJCC stage. Higher tumor grades were also associated with decreased OS, although the numbers compared were small. Primaries of the nasosinal region fared poorly when compared with other locations. Total recurrence-free survival, local and distant recurrence rates were distinctly better in primaries of the oral cavity/oropharynx when compared with those in other locations. Reduced distant recurrence-free survival was significantly associated with increasing stage. No other variables were predictive for recurrence. Additionally, we found that nasosinal tumors were more likely to display higher stage at presentation, and were more often associated with perineural invasion. Also of interest was the association of perineural invasion with margin status, with 15 of 20 patients with positive margins displaying perineural invasion, while only 5 of 17 with negative margins showed nerve invasion (P = 0.02). On immunohistochemistry, 2 cases of the 29 (7%) tumor specimens found displayed HER-2/neu positivity. No correlation between clinical behavior and positive staining could be demonstrated. Our data concur with previous reports on ACC in terms of survival and recurrence statistics. Stage and site of primary were important determinants of outcome. Grade may still serve a role in decision making. We could not demonstrate any differences attributable to primary modality of therapy, perhaps due to the nonrandomization of patients into the various treatment tracks and the inclusion of palliative cases. Similarly, perineural invasion, radiation dose and field size, and HER-2/neu positivity did not prove to be important factors in our experience. © 2001 Wiley-Liss, Inc. [source]


Multiple primary malignancies in Spanish patients with hepatocellular carcinoma: Analysis of a hospital-based tumor registry

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 8 2009
Mario Fernández-Ruiz
Abstract Background and Aim:, Little is known about the etiological associations and clinical features of extrahepatic primary malignant (EHPM) neoplasms in subjects with hepatocellular carcinoma (HCC). The aim of this study was to characterize this phenomenon in a consecutive series of Spanish patients in order to define its natural history and influence on survival. Methods:, A retrospective analysis of 245 patients with HCC during the period 1999,2003 was performed. Subjects identified with a second primary malignancy elsewhere constituted the EHPM group and were compared to patients with HCC alone. Results:, Eighteen patients (7.3%) had one or two associated extrahepatic malignancies (mean age 67.7 ± 9.7 years); of these, 17 had double cancer and one patient, triple. Nine of the 19 EHPM occurred before HCC diagnosis. The associated cancers included five cases of colorectal carcinoma, four cases of head and neck carcinoma, three cases of genitourinary cancer, two cases of lymphoproliferative disorder, one lung carcinoma, one skin melanoma, one breast carcinoma, and two cancers of unknown origin. Age and sex distribution, etiology of underlying hepatopathy, and liver function tests did not differ significantly between both groups. There was no difference between the overall survival rates. Conclusions:, EHPM is not rare among Spanish patients with HCC, although no specific clinicopathological features were detected in this population. Our results suggest that the association of another primary tumor with HCC does not imply a worse prognosis. The possibility of development of EHPM should be kept in mind when deciding on therapy and follow-up of HCC. [source]


Pancreatic adenocarcinoma in a young patient population,12-year experience at Memorial Sloan Kettering Cancer Center

JOURNAL OF SURGICAL ONCOLOGY, Issue 1 2009
A. Duffy MD
Abstract Background There is a dearth of data in a younger population of patients with pancreatic ductal adenocarcinoma (PAC) regarding epidemiology, genetics, prognosis, and outcome. This report examines a large cohort of patients with PAC ,45 years of age evaluated at MSKCC over a 12-year period. Methods A retrospective analysis of patients referred to MSKCC with PAC identified from the institutional tumor registry, who were ,45 years on the date of the diagnostic biopsy, between January 1995 and February 2008, was performed. Information reviewed included demographics, clinical and pathological staging, surgical management, therapy, date of relapse, death or last follow-up. Survival curves were estimated using the Kaplan,Meier method and compared using the log-rank test. Results One hundred thirty-six cases of PAC, age ,45 years at diagnosis, were identified. Seventy-four (54%) females, 62 (46%) males. Age range: 24,45; 4, 38, and 94 patients in age groups 20,29, 30,39, 40,45 years, respectively. Fifty (37%) had a smoking history. Fourteen (10.3%) had a positive family history of PAC. Thirty-five (25.7%) underwent a curative resection for localized disease. Twenty-eight (20.1%) presented with locally advanced, inoperable disease. Sixty-eight (50%) presented as AJCC Stage IV. Twenty-three (37%) of those resected underwent adjuvant chemoradiation. Thirteen received adjuvant gemcitabine. The median overall survival for the entire cohort was 12.3 months (95% CI 10.2,14.0 months). The median overall survival for the patients with locally resectable disease was 41.8 months (95% CI 20.3,47 months). The median overall survival for the patients who presented with locally advanced, unresectable disease was 15.3 months (95% CI 12,19.3 months). The median overall survival for those who presented with metastatic disease was 7.2 months (95% CI 5.2,9.5 months). Conclusions This is the largest reported cohort of young patients with PAC ,45 years of age. The data suggest that patients with stages I,II disease may have an improved prognosis, however the prognosis for stages III,IV patients appears to be similar to the typical (older) patient population with PAC.

Liver transplantation in association with hepatocellular carcinoma: An update of the international tumor registry

LIVER TRANSPLANTATION, Issue 9 2002
Ernesto P. Molmenti
Hepatocellular carcinoma is an epithelial tumor derived from hepatocytes that accounts for more than 80% of all primary hepatic tumors. The severity of the underlying disease is almost always the key factor in deciding whether to consider liver resection or transplantation as its treatment. Data in our registry corresponding to almost 800 patients from transplant centers throughout the world showed that patient survival after liver transplantation was significantly affected by histologic grade, tumor size >5 cm, and the presence of positive nodes. Recurrence-free survival showed a correlation with tumor size >5 cm, positive nodes, bilobar spread, and vascular invasion. At the present time, 59% of patients in our registry are alive, 84% of whom are free of tumor. Of those who died, half did so without evidence of tumor. [source]


Exercise and quality of life during and after treatment for breast cancer: results of two randomized controlled trials

PSYCHO-ONCOLOGY, Issue 4 2009
Lisa A. Cadmus
Abstract Objective: To determine the effect of exercise on quality of life in (a) a randomized controlled trial of exercise among recently diagnosed breast cancer survivors undergoing adjuvant therapy and (b) a similar trial among post-treatment survivors. Methods: Fifty newly diagnosed breast cancer survivors were recruited through a hospital-based tumor registry and randomized to a 6-month, home-based exercise program (n=25) or a usual care group (n=25). In a separate trial, 75 post-treatment survivors were randomized to a 6-month, supervised exercise intervention (n=37) or to usual care (n=38). Participants in both studies completed measures of happiness, depressive symptoms, anxiety, stress, self-esteem, and quality of life at baseline and 6 months. Results: Forty-five participants completed the trial for newly diagnosed survivors and 67 completed the trial for post-treatment survivors. Good adherence was observed in both studies. Baseline quality of life was similar for both studies on most measures. Exercise was not associated with quality of life benefits in the full sample of either study; however exercise was associated with improved social functioning among post-treatment survivors who reported low social functioning at baseline (p<0.05). Conclusions: Exercise did not affect quality of life in either recently diagnosed or post-treatment breast cancer survivors; however this may be due in part to relatively high baseline functioning among participants in both studies. Strategies for future research include limiting enrollment to survivors who report reduced quality of life on screening questionnaires and targeting survivor subgroups known to be at particular risk for quality of life impairment.

Breast-Conservation Treatment Outcomes: A Community Hospital's Experience

THE BREAST JOURNAL, Issue 1 2009
Barbara D. Florentine MD
Abstract:, In the United States, the majority of early breast cancer patients choose breast-conserving treatment in the community setting, yet there is a paucity of literature describing outcomes. In this paper, we describe our experience with breast-conserving treatment in a small community hospital. Our hospital tumor registry was used to identify breast cancer cases diagnosed at our hospital between 1997 and 2003. We limited our study to those women with initial attempts at breast-conserving surgery (BCS) who had follow-up oncology treatment at on-campus affiliated oncological services. We looked at factors that influence survival for early stage 0,II disease such as tumor and patient characteristics, completeness of local surgical tumor excision, and adjuvant treatment. We also evaluated the percentage of cases in which the initial BCS did not achieve adequate surgical oncological results and the number and type of subsequent surgeries that were required to achieve this goal. There were 185 cases with a median patient age of 55 and a median follow-up time of 53 months. Most tumors were stage 0,I (68%) or stage II (23%). A single surgery was deemed sufficient to achieve the desired oncological outcome in 54% of cases; the remaining cases (46%) required additional surgeries. A final margin of 5 mm or greater was successfully achieved in 81% of cases. Ninety-two percent of the patients underwent radiotherapy, 65% received hormonal therapy, and 49% underwent chemotherapy. One hundred and sixty one patients had successful breast-conserving surgeries (87%) and 24 patients (13%) ultimately required mastectomy. There were four loco-regional recurrences and 19 deaths during the study period. Our disease-free survival rate for early-stage cancer (stage 0,II) was 91% at 5 years. Our study shows that high-quality patient outcomes for breast-conserving treatment can be achieved in the community setting. [source]


Human papillomavirus and WHO type I nasopharyngeal carcinoma,,

THE LARYNGOSCOPE, Issue 10 2010
Emily J. Lo BA
Abstract Objectives: Nasopharyngeal carcinoma (NPC) is a rare cancer in the United States. An association between NPC and Epstein-Barr virus (EBV) is well-established for World Health Organization (WHO) types II and III (WHO-II/III) NPC but less well-established for WHO type I (WHO-I) NPC. Given the rise in oropharyngeal tumors positive for high-risk human papillomavirus (HPV) and the unique biology of WHO-I NPC, we examined the relationship between HPV and WHO-I NPC. Study Design: Retrospective case-comparison study. Methods: A search of a large multidisciplinary cancer center tumor registry identified 183 patients seen from January 1999 to December 2008 with incident NPC and no prior cancer. Available paraffin-embedded tumor specimens (N = 30) were analyzed for oncogenic HPV status by in situ hybridization (ISH) and polymerase chain reaction (PCR) for HPV-16 and HPV-18; EBV status by ISH; and p16 expression by immunohistochemistry. Demographic parameters, including race and smoking, were obtained from the medical records. Results: Among the 18 WHO-I NPC patients, 66% (N = 12) were smokers and 17% (N = 3) Asian; among the 165 WHO-II/III NPC patients, 44% (N = 73) were smokers and 24% (N = 39) Asian. Eight WHO-I NPC patients had available paraffin blocks; five of six were HPV-16-positive by PCR and four of eight were HPV-positive by ISH; only two of eight (25%) were EBV-positive. Twenty-two WHO-II/III NPC patients had available paraffin blocks; only 1 was HPV-positive by ISH, and 13 of 22 (60%) were EBV-positive. Conclusions: These results suggest that WHO-I NPC is associated with oncogenic HPV, although larger studies are needed to verify these findings. Laryngoscope, 2010 [source]


Quality of Life, Functional Outcome, and Costs of Early Glottic Cancer,

THE LARYNGOSCOPE, Issue 1 2003
Jonathan C. Smith MD
Abstract Objective To analyze quality of life, functional outcome, and hidden costs by primary treatment with surgery or radiation therapy in patients with early glottic cancer. Study Design Retrospective study in a tertiary care facility. Methods A group of 101 patients with carcinoma in situ and T1 invasive squamous cell carcinoma treated primarily with either surgery or radiation, between January 1990 and December 2000, were identified from searching our tumor registry. Patients completed two previously validated questionnaires and one local questionnaire. Statistical significance was assessed with the rank sum test, ,2 test, or Fisher's Exact test. Results Questionnaires were completed in 59% (44 of 74) of the surgical cohort and 41% (11 of 27) of the radiation therapy cohort. The primary surgical treatments were endoscopic excision (86%), hemilaryngectomy (12%), and total laryngectomy (1%). Patient-reported problems with swallowing, chewing, speech, taste, saliva, pain, activity, recreation, and appearance showed no difference between the endoscopic excision or radiation therapy cohorts. Comparing endoscopic excision versus radiation therapy, respectively, median number of treatments (2 vs. 35), total median travel distance (150 vs. 660 miles), total median travel time (180 vs. 1440 min), and total median number of hours of work missed (76 vs. 24) all differed significantly (P <.01). Conclusions Almost all patients with early glottic cancer, whether treated with surgery or radiation therapy, reported excellent quality of life outcomes and functional results. In addition to actual costs, the hidden costs for radiation therapy versus endoscopic excision were all greater in terms of total number of hours of work missed, total travel time, and total travel distance.

Frequency of constitutional MSH6 mutations in a consecutive series of families with clinical suspicion of HNPCC

A large majority of constitutional mutations in hereditary non-polyposis colorectal cancer (HNPCC) are because of the MHL1 or MSH2 genes. In a lower fraction of cases, another gene of the mismatch repair (MMR) machinery, MSH6, may be responsible. Families with MSH6 mutations are difficult to recognize, as microsatellite instability (MSI) may not be detectable and immunohistochemistry (IHC) may give ambiguous results. In the present study, we proposed (i) to determine the frequency of MSH6 mutations in a selected population of colorectal cancer patients obtained from a tumor registry, (ii) to assess whether IHC is a suitable tool for selecting and identifying MSH6 mutation carriers. One hundred neoplasms of the large bowel from suspected HNPCC families were analyzed for MSI (BAT25 and BAT26 markers) and immunohistochemical expression of the MSH6 protein. We found on 12 tumors (from different families) showing instability or lack of MSH6 expression. Among these, four potentially pathogenic MSH6 mutations were detected (del A at 2984; del TT at 3119; del AGG cod 385; and del CGT cod 1242) by direct gene sequencing. These represented 12.9% of all families with constitutional mutations of the DNA MMR genes. Thus, some 5% of all HNPCC families are featured by constitutional mutation of the MSH6 gene. This appears, however, as a minimum estimate; routine use of IHC and the study of large numbers of individuals and families with little or no evidence of Lynch syndrome might reveal that mutation of this gene account for a large fraction of HNPCC.
