Selected AbstractsSentinel node biopsy in patients with cutaneous melanoma of the head and neck: Recurrence and survival studyHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2008Fernando Gomez-Rivera MD Abstract Background. Controversy remains regarding the benefits of sentinel lymph node (SLN) biopsy for predicting survival in cutaneous melanoma of the head and neck (CMHN). Methods. We analyzed the factors associated with the recurrence and survival of CMHN patients treated in our institution. Results. One hundred thirteen patients underwent SLN biopsy for CMHN in a 12-year period. SLN identification was successful in 96%, with a median of 3 SLNs per patient. Positive-SLNs were identified in 21%. With a median follow-up of 34 months, 28% recurred. Disease-free survival (DFS) and overall survival (OS) rates were 66% and 78% in patients with SLN-negative, and 39% and 62% in SLN-positive disease. In multivariate analysis, greater Breslow-thickness was associated with decreased DFS rate (HR 2.07, CI 1.04,4.09), and age >60 years (HR 3.53, CI 1.32,9.4) with lower 5-year OS rate. Conclusion. Primary tumor thickness and age were associated with decreased survival, whereas SLN status showed a trend for prognostic significance in CMHN. © 2008 Wiley Periodicals, Inc. Head Neck, 2008 [source] Survival outcomes with the use of surgery in limited-stage small cell lung cancer,CANCER, Issue 5 2010Should its role be re-evaluated? Abstract BACKGROUND: Although chemotherapy and radiation therapy currently are recommended in limited-stage small cell lung cancer (L-SCLC), several small series have reported favorable survival outcomes in patients who underwent surgical resection. The authors of this report used a US population-based database to determine survival outcomes of patients who underwent surgery. METHODS: The Surveillance, Epidemiology, and End Results (SEER) registry was used to identify patients who were diagnosed with L-SCLC between 1988 and 2002 coded by SEER as localized disease (T1-T2Nx-N0) or regional disease (T3-T4Nx-N0). Kaplan-Meier and Cox regression analyses were used to compare overall survival (OS) for all patients. RESULTS: In total, 14,179 patients were identified, including 863 patients who underwent surgical resection. Surgery was associated more commonly with T1/T2 disease (P < .001). Surgery was associated with improved survival for both localized disease and regional disease with improvements in median survival from 15 months to 42 months (P < .001) and from 12 months to 22 months (P < .001), respectively. Lobectomy was associated with the best outcome (P < .001). Patients with localized disease who underwent lobectomy with had a median survival of 65 months and a 5-year OS rate of 52.6%; whereas patients who had regional disease had a median survival of 25 months and a 5-year OS rate of 31.8%. On multivariate analysis, the benefit of surgery varied in a time-dependant fashion. However, the benefit of lobectomy remained across all time intervals (P = .002). CONCLUSIONS: The use of surgery, and particularly lobectomy, in selected patients with L-SCLC was associated with improved survival outcomes. Future prospective studies should consider the role of surgery as part of the multimodality management of this disease. Cancer 2010. © 2010 American Cancer Society. [source] Mantle Cell Lymphoma in the Ocular RegionACTA OPHTHALMOLOGICA, Issue 2008S HEEGAARD Purpose To characterize the clinicopathological features of mantle cell lymphoma (MCL) in the ocular region. Methods All lymphoid lesions were retrieved searching the Danish Ocular Lymphoma Database 1980-2007. Specimens were collected from Danish pathology departments and re-evaluated with a panel of monoclonal antibodies. For all patients with confirmed MCL the complete clinical files were collected and reviewed. Results Twenty-one patients with MCL were identified comprising nine percent (21/230) of all lymphomas in the ocular region. There were 18 male and three female patients with an age range from 60 to 90 years (median 75 years). Ocular region MCL as first presenting symptom included 67% of the patients. Of these, 71% had bilateral involvement and all had lymphoma in more than one site within the ocular region. The orbit (71%) and eyelids (64%) were the most commonly affected sites. At the time of diagnosis 93% of the patients were in Ann Arbor stage III/IV, with bone marrow involvement (79%) and B-symptoms (50%). Median overall survival (OS) was 30 months and the five-year OS rate was 21%. Patients receiving anti-CD20 (Rituximab)-containing chemotherapy had a significant better 5-year OS rate (80 %) (p < 0,027) than patients in treatment regimes without Rituximab (5-year OS rate, 29%). Conclusion MCL presenting in the ocular region has a male predominance and affects elderly patients. The orbit and eyelids were frequently involved. Patients with ocular region MCL as first presenting symptom had a high proportion of bilateral affection. Patients had advanced stage disease at diagnosis, multiple relapses and a low 5-year OS rate similar to systemic MCL. Treatment with Rituximab-containing chemotherapy improved survival significantly. [source] Low drug resistance to both platinum and taxane chemotherapy on an in vitro drug resistance assay predicts improved survival in patients with advanced epithelial ovarian, fallopian and peritoneal cancerINTERNATIONAL JOURNAL OF CANCER, Issue 11 2009Koji Matsuo Abstract The objective of this study was to evaluate the role of an in vitro drug resistance assay to platinum and taxane in the management of advanced epithelial ovarian, fallopian and primary peritoneal cancer. All patients with FIGO Stage IIIc and IV who received postoperative chemotherapy with platinum and taxane for more than 4 courses after the initial cytoreductive surgery between 1995 and 2008 were evaluated. Patients who received neoadjuvant chemotherapy were not included. An in vitro drug resistance assay (EDR Assay, Oncotech, Tustin, CA) was used to determine drug resistance for each patient's tumor tissue. Level of drug resistance was described as extreme (EDR), intermediate (IDR), or low (LDR). Response to chemotherapy and survival were correlated to the EDR Assay. Of the 335 patients who underwent primary cytoreductive surgery, 173 cases met the criteria for statistical evaluation. The 58 patients (33.5%) whose tumors had LDR to both platinum and taxane had statistically improved progression-free survival and overall survival (OS) compared with the 115 patients (66.5%) who demonstrated IDR or EDR to platinum and/or taxane (5-year OS rates, 41.1% vs. 30.9%, p = 0.014). The 5-year OS rates for the 28 (16.2%) cases that had optimal cytoreduction with LDR to both platinum and taxane was significantly improved over the 62 (35.8%) cases that were suboptimally cytoreduced with IDR or EDR to platinum and/or taxane (54.1% vs. 20.4%, respectively, p < 0.001). In conclusion, LDR to both platinum and taxane chemotherapy, as determined by an in vitro drug resistance assay, independently predicts improved survival in patients with advanced epithelial ovarian, fallopian and peritoneal cancer, especially in those patients who undergo optimal primary cytoreduction. © 2009 UICC [source] Intensive induction chemotherapy with regimen containing intermediate dose cytarabine in the treatment of de novo acute myeloid leukemia,AMERICAN JOURNAL OF HEMATOLOGY, Issue 7 2009Jiazhuo Liu To improve long-term outcome of de novo acute myeloid leukemia (AML) patients by intermediate dose of cytarabine integrated in induction therapy and to explore the impact of cytogenetic abnormalities on the prognosis. Eighty-seven AML patients were treated with HAD regimen containing intermediate dose cytarabine (IDAra-C) as induction therapy, 83 from which with karyotype results were divided into three cytogenetic groups according to SWOG criteria. Complete remission (CR) rate, disease-free survival (DFS), and overall survival (OS) among different groups were evaluated. The CR rate of the 87 cases was 80/87 (92%). Median DFS and OS have not reached (NR). DFS rates at 1 and 3 years were 76.3% and 63.4%, respectively. OS rates at 1 and 3 years were 86.0% and 58.7%, respectively. According to SWOG criteria, CR rate, median DFS, and OS were 100%, NR and NR for the favorable group; 88.9%, NR, and 16 months for the intermediate group; 83.3%, 4.5 months, and 7.5 months for the adverse group. The differences among the three groups were statistically significant excepting for CR rate between adverse and intermediate groups. HAD regimen containing IDAra-C as induction chemotherapy regimen is effective in de novo AML of adult patients and can achieve higher CR rate and longer survival than standard dose of cytarabine (SDAra-C) regimen. Most of the patients were able to endure the therapy. Cytogenetics is still an important prognostic factor despite of the incorporation of IDAra-C in induction chemotherapy. The differences among the three groups were statistically significant. Am. J. Hematol., 2009. © 2009 Wiley-Liss, Inc. [source] Absolute lymphocyte count at the time of first relapse predicts survival in patients with diffuse large B-cell lymphomaAMERICAN JOURNAL OF HEMATOLOGY, Issue 2 2009Luis F. Porrata Peripheral blood absolute lymphocyte count (ALC) is a survival prognostic factor in hematological malignancies. No reports have addressed whether ALC at the time of first relapse (ALC-R) predicts survival. Thus, we assessed the prognostic significance of ALC-R in diffuse large B-cell lymphoma (DLBCL). Patients were required to have been diagnosed with first relapsed DLBCL, have ALC-R values, and to be followed at Mayo Clinic, Rochester. From Feb 1987 until March 2006, 97 first relapsed DLBCL patients qualified for the study. The overall survival (OS) and progression-free survival (PFS) were measured from the time of first relapse. The value of ALC- R , 1.0 × 109/L was used for the analysis. Both groups (ALC-R , 1 or < 1 × 109/L) were balanced for the international prognostic index at relapse (IPI-R) (P = 0.3), and for autologous stem cell transplantation (P = 0.4). Superior OS and PFS were observed with an ALC-R , 1.0 × 109/L (N = 60) versus ALC-R < 1.0 × 109/L (N = 37) [median OS: 28.7 months, 5 years OS rates of 39% versus median OS: 10.2 months, 5 years OS rates of 14%, P < 0.002; and median PFS: 14.8 months, 5 years PFS rates of 21% versus median PFS: 6.5 months, 5 years PFS rates of 8%, P < 0.004, respectively]. ALC-R was an independent prognostic factor for OS [RR = 0.4, P < 0.01] and PFS [RR = 0.5, P < 0.005]. ALC-R predicts survival suggesting that host immunity is an important variable predicting survival in first relapsed DLBCL. Am. J. Hematol. 2009. © 2008 Wiley-Liss, Inc. [source] Long-term data on the survival of patients with prostate cancer treated with radical prostatectomy in the prostate-specific antigen eraBJU INTERNATIONAL, Issue 1 2010Hendrik Isbarn Study Type , Therapy (case series) Level of Evidence 4 OBJECTIVE To examine the long-term rates of biochemical recurrence (BCR)-free survival, cancer-specific mortality (CSM)-free survival, and overall survival (OS) in patients with prostate cancer treated with open radical prostatectomy (RP) in the prostate-specific antigen (PSA) era. PATIENTS AND METHODS The study comprised 436 patients who were treated with RP between 1992 and 1997 at our institution. None received adjuvant/salvage therapy in the absence of BCR. The BCR-free, CSM-free and OS rates were defined using the Kaplan-Meier method. Multivariable Cox-regression models were used to test the effect of age, preoperative PSA level, neoadjuvant hormonal therapy, pT stage, lymph node status, RP Gleason sum and surgical margin status on BCR. RESULTS The median follow-up of censored patients was 122, 128, and 132 months for, respectively, BCR-free, CSM-free and OS estimates. The 10-year event-free survival rates for the same endpoints were 60%, 94% and 86%, respectively. Preoperative PSA level, RP Gleason sum, pT stage, lymph node status, and surgical margin status were independent predictors of BCR (all adjusted P < 0.05). CONCLUSIONS This study is the first to evaluate the long-term cancer control outcomes after RP from a European country in the PSA era. Our data indicate that RP provides excellent long-term survival rates in patients with clinically localized prostate cancer. Although ,40% of patients have BCR after 10 years of follow-up, the CSM rate after 10 years is as low as 6%. [source] The role of postoperative radiotherapy for the treatment of gangliogliomasCANCER, Issue 2 2010Dirk Rades MD Abstract BACKGROUND: Because of their rarity, no prospective studies have been performed regarding gangliogliomas. The optimal treatment regimen is unclear. In this study, the authors compared 4 therapies for local control (LC) and overall survival (OS) in patients with ganglioglioma. METHODS: In 402 patients with ganglioglioma, outcomes were compared for patients who underwent gross total resection alone (GTR) (n = 188), GTR plus radiotherapy (GTR + RT) (n = 21), subtotal resection alone (STR) (n = 113), and STR plus RT (STR + RT (n = 80). Age, sex, tumor site, and histologic grade also were investigated. Subgroup analyses were performed for both low-grade and high-grade tumors. RESULTS: The 10-year LC rates were 89% after GTR, 90% after GTR + RT, 52% after STR, and 65% after STR + RT (P < .001); and the 10-year OS rates were 95%, 95%, 62%, and 74%, respectively (P < .001). After STR, irradiation significantly improved LC (P = .004) but not OS (P = .22). After GTR, irradiation did not significantly improve LC (P = .23) or OS (P = .29). On multivariate analyses, LC and OS were associated with therapy and pathologic grade, and OS also was associated with tumor site. In low-grade tumors, STR + RT resulted in better LC (P = .016) but not better OS (P = .18); and, after GTR, LC (P = .28) and OS (P = 1.0) were not improved with postoperative radiotherapy. In high-grade tumors, STR + RT resulted in better LC (P = .016) but not better OS (P = .41); after GTR, LC (P = .56) and OS (P = .61) were not improved with irradiation. CONCLUSIONS: According to this review, GTR should be performed whenever safely possible and does not require postoperative irradiation. If only STR is achieved, then RT improves LC of both low-grade and high-grade tumors and, thus, should be considered seriously. Cancer 2010. © 2010 American Cancer Society. [source] Anthracycline-fludarabine-containing regimens with or without rituximab in the treatment of patients with advanced follicular lymphoma,CANCER, Issue 9 2009Stefano Luminari MD Abstract BACKGROUND: Recent experience has suggested that there has been a stepwise improvement in the survival outcomes of patients who have follicular lymphoma with the introduction of new treatment options. In the current study, the authors report the results of 2 subsequent phase 2 trials of 238 previously untreated patients. METHODS: In a trial of bleomycin, epidoxorubicin, cyclophosphamide, vincristine, and prednisone (BACOP) plus fludarabine, mitoxantrone, and dexamethasone (FND), 144 patients received 2 BACOP treatments followed by 4 FND treatments. In a trial of BACOP plus fludarabine and rituximab (FR), 94 patients received 3 BACOP treatments followed by 4 FR treatments. RESULTS: The complete remission (CR) rate for BACOP/FND was 62%. After a median follow-up of 60 months, the failure-free survival (FFS) and overall survival (OS) rates at 4 years were 53% and 77%, respectively. The CR rate for BACOP/FR was 79%. After a median follow-up of 36 months, the FFS and OS rates at 4 years were 56% and 97%, respectively, which were significant compared with the CR and OS rates achieved with BACOP/FND. Twenty-five of 42 bcl -2-positive patients attained a molecularly negative CR and had improved FFS. No significant differences were observed between the 2 trials in the percentage of infections or neutropenia. CONCLUSIONS: The CR and OS rates achieved with BACOP/FR were better, and overall toxicity did not increase. Furthermore, patients who received rituximab had a better FFS compared with patients who received chemotherapy alone. Finally, although conclusions between nonrandomized groups may depend on differences in observed and unobserved prognostic features, the current results suggested that the addition of rituximab to anthracycline-fludarabine,containing regimens have a favorable effect on the prognosis of patients with advanced follicular lymphoma.

[source] Influence of compartmental involvement on the patterns of morbidity in soft tissue sarcoma of the thighCANCER, Issue 1 2009Andreas Rimner MD Abstract BACKGROUD: The authors sought to determine whether differences existed in patterns of outcome and morbidity between the 3 thigh compartments after limb-sparing surgery and postoperative radiation therapy (RT). METHODS: A total of 255 patients with primary soft tissue sarcoma (STS) of the thigh were identified in our sarcoma database (1982,2002). More than 80% of tumors were >5 cm, high grade, and deep; 33% had close or positive microscopic resection margins. Adjuvant RT consisted of brachytherapy alone (BRT; 63%), external beam RT alone (EBRT; 31%), or a combination of brachytherapy and EBRT (6%). There were 125 anterior, 58 medial, and 72 posterior lesions. The 3 compartments were balanced as to tumor grade, size, depth, margin status, and RT type. RESULTS: Overall local control (LC) was 89%, distant metastases-free survival (DMFS) was 61%, and overall survival (OS) was 66% at 5 years (median follow-up, 71 months). Overall rates for complications at 5 years were wound reoperation (10%), edema (13%), joint stiffness (12%), nerve damage (8%), and bone fractures (7%). Wound reoperation and edema were significantly higher for medial-compartment tumors (P = .01 and .005, respectively), whereas nerve damage occurred more frequently in posterior-compartment tumors (P < .001). There were no differences among bone fracture, joint stiffness, DMFS, or OS rates between compartments. CONCLUSIONS: Although tumor control was similar for all 3 compartments, more wound reoperation and edema were observed in the medial compartment, and more nerve damage was noted in the posterior compartment. These results may help guide decisions concerning current patients and improve the design of future treatments tailored to compartments. Cancer 2009. © 2008 American Cancer Society. [source] Predictive and discriminating three-risk-group prognostic scoring system for staging Hodgkin lymphomasCANCER, Issue 2 2007Delphine Maucort-Boulch MD Abstract BACKGROUND. Several 3-stage Ann Arbor classification-derived prognostic systems were constructed since 1980 to identify the prognosis of Hodgkin lymphoma (HL). Modern statistical tools were applied to 955 patients treated between 1981 and 1996 to build a 3-stage prognostic scoring system (PSS). METHODS. Each variable associated with 10-year overall survival (10-year OS) was assigned to 2 (0 or 1) or 3 (0, 1 or 3) values. By summing the values attributed to each variable, 3 stages were defined. 10-year OS, 5-year event-free survival (5-year EFS), and freedom from progression (5-year FFP) rates of the PSS and of other existing systems were then compared. RESULTS. Four variables were associated with 10-year OS: age (<40 = 0, ,40 = 1), number of involved lymphoid areas (1,2 = 0, 3,4 = 1, ,5 = 2), visceral disease (no = 0, yes = 1), and systemic symptoms (no = 0, yes = 1). Scores 0 and 1, 2 and 3, and ,4 were attributed to 59.7%, 30.9%, and 9.4% of the patients who had 10-year OS rates of 93.5, 75.7, and 53.4% and 5-year EFS / 5-year FFP rates of 91.2%/90.3%, 78.1%/76.3%, and 54.1%/52.6%, respectively. The discrimination and prediction abilities of the PSS were better than those of the other systems tested; moreover, the PSS adequately identified the few patients with a worse prognosis without resorting to the International Prognostic Score for advanced stages. The PSS was also highly predictive for 489 patients treated between 1997 and 2002. CONCLUSION. PSS is a useful alternative to the existing prognostic systems for evaluating HL patients.

[source] Hepatic artery chemoembolization for 110 gastrointestinal stromal tumorsCANCER, Issue 12 2006Response, prognostic factors, survival Abstract BACKGROUND. The efficacy of hepatic artery chemoembolization (HACE) was evaluated for gastrointestinal stromal tumors (GISTs) metastatic to the liver. METHODS. Records for patients with metastatic GIST who underwent HACE between January 1993 and March 2005 were reviewed and cross-sectional images were used to determine objective tumor response. Progression-free survival in the liver (PFS-liver) and overall survival (OS) were calculated with the Kaplan,Meier method. Patient, tumor, and treatment variables were analyzed to identify factors influencing survival. RESULTS. Of the 110 patients identified, the radiologic response to HACE could be evaluated in 85 patients, 12 of whom (14%) demonstrated partial responses, 63 of whom (74%) demonstrated stable disease, and 10 of whom (12%) demonstrated progressive disease. PFS-liver rates were 31.2%, 8.2%, and 5.4% at 1, 2, and 3 years, respectively; the median PFS time was 8.2 months. OS rates were 62% at 1 year, 32% at 2 years, and 20% at 3 years; the median OS time was 17.2 months. Patients who had >5 liver metastases and received only 1 HACE treatment were found to have a shorter PFS compared with patients with fewer metastases or those who received ,2 HACE sessions. Extensive liver involvement, the presence of extrahepatic metastases, and progression of liver disease after HACE were associated with poor OS. Use of imatinib prolonged OS time. CONCLUSIONS. HACE produced a durable tumor response or disease stabilization in the majority of patients with GISTs metastatic to liver. Extent of liver disease, presence of extrahepatic disease, number of embolization treatments, and use of imatinib were found to have prognostic influence on PFS, OS, or both.

[source] Pregnancy and early-stage melanoma,CANCER, Issue 9 2003Deepu Daryanani M.D. Abstract BACKGROUND Cutaneous melanomas are aggressive tumors with an unpredictable biologic behavior. It has been suggested that women who present with melanoma during pregnancy have a worse prognosis due to more aggressive behavior of the melanoma. The objective of the current study was to evaluate the long-term effect of pregnancy on disease progression in women with Stage I,II melanoma. METHODS From 1965 to 2001, 46 pregnant women were treated for a Stage I,II melanoma at the University Medical Center Groningen. These patients were compared with an age-matched and gender-matched control group (nonpregnant) of 368 women with Stage I,II melanoma. The patients were staged according to the 2002 American Joint Committee on Cancer TNM classification system for melanoma. The 10-year disease-free survival (DFS) and 10-year overall survival (OS) rates were calculated using logistic regression analysis. RESULTS The median age of patients in the pregnant group was 30 years (range, 18,46 years), and the median age of patients in the nonpregnant group was 36 years (range, 17,45 years). The median follow-up was 109 months (range, 1,356 months). Pregnant patients presented more often with thicker melanomas (median, 2.0 mm vs. 1.7 mm; not statistically significant). No differences with regard to tumor location, histologic subtype, tumor ulceration, or vascular invasion were detected between the pregnant group and the nonpregnant group. There was no statistical difference in the 10-year DFS and 10-year OS rates between the two groups. The 10-year DFS rates for patients in the pregnant and nonpregnant groups, respectively, were 88% versus 86% for patients with Stage I melanoma and 67% versus 73% for patients with Stage II melanoma. The 10-year OS rates for patients in the pregnant and nonpregnant groups, respectively, were 94% versus 90% for patients with Stage I melanoma and 82% versus 81% for patients with Stage II melanoma. CONCLUSIONS Pregnancy does not appear to have an adverse, long-term effect on survival in patients with clinically localized melanoma. Further studies should address whether pregnant patients present with thicker lesions and/or whether they have decreased DFS compared with nonpregnant women. The prognosis for women with melanoma during pregnancy, as it relates to survival, still is dependent on tumor thickness and ulceration. Cancer 2003;97:2248,53. © 2003 American Cancer Society.
