Selected AbstractsQuality of life among long-term survivors of breast cancer: different types of antecedents predict different classes of outcomesPSYCHO-ONCOLOGY, Issue 9 2006Charles S. Carver Abstract Quality of life (QOL) has many aspects, both in the short-term and in the long-term. Different aspects of QOL may have different types of precursors: demographic, medical, and psychosocial. We examined this possibility in a group of long-term breast cancer survivors. Early-stage breast cancer patients (N=163) who had provided information about medical, demographic, and psychosocial variables during the year after surgery completed a multidimensional measure of QOL 5,13 years later. Initial chemotherapy and higher stage predicted greater financial problems and greater worry about appearance at follow-up. Being partnered at diagnosis predicted many psychosocial benefits at follow-up. Hispanic women reported greater distress and social avoidance at follow-up. Initial trait optimism predicted diverse aspects of better psychosocial QOL at follow-up, but not other aspects of QOL. Thus, different aspects of QOL at long-term follow-up had different antecedents. Overall, psychological outcomes were predicted by psychosocial variables, presence of a partner at diagnosis, and ethnicity. Financial outcomes, in contrast, were predicted by medical variables, which otherwise predicted little about long-term QOL. This divergence among aspects of QOL should receive closer attention in future work. Copyright © 2005 John Wiley & Sons, Ltd. [source] Analysis of chromosomal changes in serous ovarian carcinoma using high-resolution array comparative genomic hybridization: Potential predictive markers of chemoresistant diseaseGENES, CHROMOSOMES AND CANCER, Issue 1 2007Sang Wun Kim The mechanism of drug resistance in cancer is multifactorial, and the accumulation of multiple genetic changes may lead to drug-resistant phenotypes. This study sought to determine characteristic genetic changes in chemoresistant serous ovarian carcinomas using high-resolution array comparative genomic hybridization (aCGH), and identified genomic aberrations that could be used as predictive markers of chemoresistant disease. Seventeen primary ovarian tumors from optimally debulked stage IIIc serous ovarian carcinoma patients were analyzed using aCGH. Ten patients had chemoresistant disease (progression within 12 months of initial chemotherapy), whereas seven patients had chemosensitive disease (no recurrence for more than 36 months). Receiver operating characteristics curve analysis was used to select chromosomal aberrations that could help distinguish chemoresistant disease from chemosensitive disease. In 17 tumors, frequent increases in DNA copy number were seen on 1p36.33, 3q26.2, 8q24.3, 10q26.3, 12p11.21, 20q13.33, and 21q22.3, and frequent losses were observed on 4p12, 5q13.2, 7q11.21, 8p23.1, 14q32.33, Xq13.3, and Xq21.31. The gains on 5p15.33 and 14q11.2, and losses on 4q34.2, 4q35.2, 5q15, 8p21.1, 8p21.2, 11p15.5, 13q14.13, 13q14.2, 13q32.1, 13q34, 16q22.2, 17p11.2, 17p12, and 22q12.3 were more frequent in chemoresistant disease. The losses on 13q32.1 and 8p21.1 had the largest areas under the curve (AUC 0.90 and 0.85, respectively). The most reliable combination of chromosomal aberrations for detecting chemoresistant disease was the loss on 13q32.1 and 8p21.1 (AUC 0.950). Our findings suggest that these chromosomal aberrations are potential predictive markers of chemoresistant disease in patients with serous ovarian carcinomas. © 2006 Wiley-Liss, Inc. [source] Extremity salvage with a free musculocutaneous latissimus dorsi flap and free tendon transfer after resection of a large congenital fibro sarcoma in a 15-week-old infant.MICROSURGERY, Issue 6 2006A case report A case of complex microsurgical reconstruction of the dorsum of the foot, including tendon transfer following tumor resection, in a 15-week-old male infant is presented. After birth, a 5.5 × 4 cm large tumor was observed on the dorsum of the right foot. Biopsy showed a congenital malignant fibro sarcoma. After initial chemotherapy a radical excision of the tumor at the age of 14 weeks was followed. To cover the defect a musculocutaneous latissimus dorsi flap was taken, the cutaneous part being large enough to cover the defect. Extensor tendons were reconstructed with free tendon transplants. Amputation is usually indicated in these cases. To the best of our knowledge, microsurgical reconstruction in infants at this age with congenital malignant tumors has not yet been reported. The case shows that Plastic surgery can play an important role in pediatric oncology and should routinely be integrated into the multi-modal treatment concepts. © 2006 Wiley-Liss, Inc.

[source] Desmoplastic small round cell tumor in childhood: The St. Jude Children's Research Hospital experiencePEDIATRIC BLOOD & CANCER, Issue 3 2007Raya Saab MD Abstract Background Desmoplastic small round cell tumor (DSRCT) is a rare, primarily intra-abdominal tumor that has a poor outcome with current therapies. Procedure We retrospectively reviewed patient characteristics, presenting symptoms, tumor pathology, treatment, and outcome of 11 pediatric patients with DSRCT at our institution. Results The cohort included 1 female and 10 male patients. Median age at diagnosis was 14 years (range 5,21 years). In eight (73%) patients, the primary tumor was abdominal or pelvic, and in one patient each, it was submental, mediastinal, and paratesticular. Nine (82%) patients had metastatic disease. All tumors showed polyphenotypic differentiation by immunohistochemistry. The EWS-WT1 transcript was detected in six of seven tumors tested. One tumor showed rhabdomyoblastic differentiation after therapy. All patients received chemotherapy; eight underwent surgical resection, seven received primary site radiation, and four received myeloablative chemotherapy with stem-cell support. Three (27%) patients are alive 23 months, 8 years, and 10 years from diagnosis. Two died of treatment-related toxicity, six died of disease. None of the patients in whom surgery and initial chemotherapy failed to induce complete remission survived. Conclusions DSRCT is an aggressive malignancy that does not respond well to contemporary treatments, and patients who do not enter complete remission after initial chemotherapy and surgery appear to have a particularly dismal outcome. Patients with localized extra-abdominal disease have a better prognosis, most likely due to increased feasibility of resection. Better understanding of molecular and genetic mechanisms of tumorigenesis and treatment-related changes may contribute to development of more effective therapy for DSRCT.

[source] The Role of Radiation Therapy in Locally Advanced Breast CancerTHE BREAST JOURNAL, Issue 2 2010Jasna But-Had Abstract:, The purpose of the study was to evaluate and compare the impact of postoperative radiotherapy, whether it was based on the clinical stage at presentation of the disease or on the pathological downstaged disease after initial chemotherapy for non-inflammatory locally advanced breast cancer (LABC). We retrospectively analyzed locoregional recurrence (LRR), relapse free survival (RFS), overall survival (OS) and disease free survival (DFS) in 55 patients treated for non-inflammatory LABC with neoadjuvant chemotherapy and surgery with or without radiotherapy. The mean follow-up was 55 months. The 3-year OS was 74%, DFS 73% and RFS 87%. The OS and DFS benefit was seen in those receiving radiation, with a mean OS of 89 months versus 68 months (p = 0.029) and mean DFS of 72 months versus 54 months (p = 0.029). Total LRR was 11% (8% versus 17% in the non-radiotherapy group, p = 0.349) and mean RFS of 95 months versus 86 months (p = 0.164). If the treatment planning was to be based on the original extent of the disease, then all patients in our study should have received adjuvant radiotherapy. Significantly lower OS and DFS without the addition of radiotherapy suggests that indication for radiation treatment should be based on the clinical pre-chemotherapy stage rather than the pathological post-chemotherapy stage. Radiation should therefore always be considered regardless of the response to initial chemotherapy for non-inflammatory LABC. [source] Paclitaxel and pegylated-liposomal doxorubicin are both active in angiosarcomaCANCER, Issue 2 2005Keith M. Skubitz M.D. Abstract BACKGROUND Paclitaxel has unique activity in angiosarcomas of the face and scalp, but its activity in angiosarcomas originating at other sites is less well defined. Paclitaxel and pegylated-liposomal doxorubicin (PLD) are highly effective in Kaposi sarcoma (KS). Because of the efficacy of PLD in soft tissue sarcoma in general, and in KS in particular, coupled with potential similarities in KS and angiosarcoma, and the apparent activity of paclitaxel in angiosarcomas, the authors treated patients with angiosarcoma with either paclitaxel or PLD as initial chemotherapy. METHODS To better define the efficacy of these agents in angiosarcoma, the authors reviewed their experience with paclitaxel and PLD in patients with angiosarcoma treated between 1994 and 2004. RESULTS They identified seven patients with angiosarcoma treated with paclitaxel, and six treated with PLD. Only one patient in the series had an angiosarcoma of the scalp. Two patients receiving paclitaxel had received previous therapy with PLD, and four of six patients treated with PLD had previously received paclitaxel. Of the eight patients treated with paclitaxel, five had major responses (three had partial responses [PR] and two had complete disease remission [CR]) and three had progressive disease (PD). Of the 6 patients who received PLD, 3 had a PR for 6, 19, and >20 months, respectively, 2 had stable disease for 7 and 11 months, respectively, and 1 had PD. CONCLUSIONS The current study demonstrated the activity of PLD (five of six patients experienced clinical benefit) and extended the data on paclitaxel in angiosarcoma, both of the face and scalp, as well as angiosarcoma originating at other sites.
