New strategies are needed in diffuse malignant mesothelioma. 总被引:7,自引:0,他引:7
BACKGROUND. Medical records of 50 patients with malignant mesothelioma were reviewed to determine the clinical features and factors influencing survival. METHODS. Charts of all patients whose conditions were diagnosed as malignant mesothelioma were abstracted and analyzed by statistical software. RESULTS. The male-to-female ratio was 4:1. The age distribution was younger than 45 years of age, 10%; 45-54 years of age, 12%; 55-64 years of age, 37%; 65-74 years of age, 33%; and 75 years of age or older, 8%. Both mean and median ages were 58 years. Among the 32 patients in whom asbestos exposure was recorded, 24 had documented exposure. The sites were pleura, 73%; peritoneum, 20%; and both, 6%. The histologic types were epithelial, 51%; sarcomatous, 10%; mixed, 15%; and not specified, 24%. The stage at presentation was Stage I, 37%; II, 39%; III, 12%; IV, 6%; and unknown, 6%. The common symptoms in pleural disease were dyspnea and pain; in peritoneal disease, abdominal distension and pain were common. The median time from first symptom to diagnosis was 3 months (range, 0-23 months). The median survival after the appearance of symptoms, the diagnosis, and the treatment were 13, 10, and 8 months, respectively. CONCLUSIONS. The survival was independent of age, sex, and smoking behavior. It was longer in patients with earlier-stage disease, a good performance status, a longer duration of symptoms, an absence of pain, and who were treated with combined surgery and chemotherapy. Chemotherapy using anthracyclines yielded more remissions (9 of 21) than that using nonanthracyclines (0 of 13). The remission rate after primary chemotherapy with anthracyclines (7 of 16) may be higher than in recurrent tumor (2 of 14). In future trials, stratification into primary chemotherapy and chemotherapy of recurrent cancer is suggested. There is a need for multitechnique trials incorporating primary chemotherapy. 相似文献

OBJECTIVE: To investigate the efficacy and safety of docetaxel monotherapy as salvage chemotherapy for advanced gastric cancer (AGC) in clinical practice and to determine the prognostic factors in these patients. METHODS: We retrospectively reviewed the medical records of patients with AGC for whom fluoropyrimidine and platinum had previously failed and who had received docetaxel salvage monotherapy between December 2000 and March 2006. Docetaxel was administered at a dose of 75 mg/m(2) intravenously every 3 weeks with dexamethasone prophylaxis. RESULTS: A total of 154 patients received 583 cycles of docetaxel with a median of three cycles per patient (range 1-10). The median age was 54 years (range 27-75 years). The objective response rate of 86 patients with measurable lesions was 14%, with 1 complete response and 11 partial responses, with a median response duration of 5.6 months. An additional 25 patients achieved stable disease. The median time to progression (TTP) for all patients was 2.6 months [95% confidence interval (CI), 2.2-2.9] and the median overall survival (OS) from the start of docetaxel chemotherapy was 7.2 months (95% CI, 5.9-8.5). The chemotherapy was generally well tolerated. Multivariate analysis showed that the Eastern Cooperative Oncology Group (ECOG) performance status (0 or 1 versus 2) was an independent prognostic factor for both TTP and OS. Disease status indicative of a relatively small tumor burden (resected metastatic or recurrent tumor) was a predictor for better TTP and good differentiation of the tumor was a predictor for better OS. CONCLUSION: Docetaxel 75 mg/m(2) is relatively active and tolerable as a second-line salvage treatment after failure of fluoropyrimidine and platinum in general clinical practice for AGC. 相似文献

BACKGROUND: A weekly continuous 24-hour infusion therapy with 5-fluorouracil (5-FU) and calcium - folinic acid (CA-FA) was shown to be an effective first-line treatment in advanced metastatic colorectal cancer. Sodium - folinic acid (S-FA) is a new formulation which, in contrast to CA-FA allows the simultaneous i.v. administration in combination with 5-FU in one pump. PATIENTS AND METHODS: From 1997 to 1998, 51 patients [median age 60 (range 24-77) years; 38 male, 13 female] with metastatic colorectal cancer were recruited in 5 centers to receive weekly 24-hour infusions of 5-FU (2,600 mg/m(2)) and S-FA (500 mg/m(2)) dissolved in one pump for 6 weeks as first-line treatment. The treatment cycle was repeated after a 2-week rest period. RESULTS: 1,178 administrations (median 24, range 3-54) were performed during the study. Out of 51 patients (median follow-up 20.2 months), 2 (3.9%) achieved complete remission (CR), 17 (33.3%) partial remission (PR), and 21 (41.2%) no change (NC). Progressive disease (PD) was observed in 11/51 (21.6%) patients, including 6 patients who did not complete the first cycle. Median time to tumor progression (TTP) was 8.5 months (95% CI: 5.8-11.3). 32/51 (62.7%) patients survived for more than 1 year, the median survival was reached at 16.5 months (95%CI: 10.2-22.8). Among major toxicities, NCICTC grade III/IV diarrhea occurred in 13/51 (25.4%), grade III hand-foot syndrome in 6/51 (11.7%) patients. Grade III/IV stomatitis was observed in 4/51 (7.8%), cardiac toxicity occurred in 2/51 patients (3.9%). CONCLUSION: Similar to conventional 24-hour 5-FU + CA-FA treatment, the combination with S-FA induced 37.2% objective responses with moderate toxicity. However, TTP seems favorable and the administration of S-FA is convenient, while saving costs and time for the patient in outpatient units. 相似文献

PURPOSE: To investigate the treatment outcome and prognostic factors of adult medulloblastoma patients who received postoperative craniospinal irradiation (RT). METHODS AND MATERIALS: Between 1983 and 2000, 30 adult patients (17 men and 13 women, age >or=16 years, median 27, range 16-45) underwent postoperative RT. The median duration of symptoms was 2 months (range 1-9). The tumor location was lateral in 16 (53%). A desmoplastic variant was seen in 12 (40%). Tumor resection was complete in 20 (67%) and incomplete in 10 (33%). All patients received craniospinal RT. The median dose to the whole brain was 40 Gy (range 36-51), to the posterior fossa 54 Gy (range 49-56), and to the spinal axis 36 Gy (range 24-40). The median interval between surgery and the start of RT was 31 days (range 12-69), and the median duration of RT was 45 days (range 34-89). Ten patients (33%) received adjuvant chemotherapy. The median follow-up was 51 months (range 5-215). RESULTS: The 5- and 8-year overall survival and disease-free survival rates were 65% and 51% and 63% and 50%, respectively. Twelve patients (40%) developed relapse, with a median follow-up of 51 months. The posterior fossa was the most common site of relapse (6 patients). The median time to relapse was 26 months (range 4-78). Fifty percent of the relapses occurred after 2 years, 17% after 5 years. In univariate analysis, M stage and the interval between surgery and the start of RT were significant prognostic factors for disease-free survival. At 5 years, 70% of M0 patients were estimated to be disease-free, but none of the 3 M3 patients reached 5 years without recurrence (p = 0.0002). The 5-year disease-free survival rate for the patients whose interval between surgery and the start of RT was <3 weeks, between 3 and 6 weeks, and >6 weeks was 0%, 85%, and 75%, respectively (p = 0.002). The 5-year posterior fossa control rate for patients who received >or=54 Gy or <54 Gy to the posterior fossa was 91% and 33%, respectively (p = 0.05). CONCLUSION: The survival results for medulloblastomas in adults compare favorably with those in children. However, late relapses, lateral tumor location, and desmoplastic histologic features are more frequent in adults. Spinal seeding at presentation is a poor prognostic factor for disease-free survival. A minimal dose of 54 Gy to the posterior fossa is essential for adequate tumor control. The interval between surgery and the start of RT, which was found to be a significant prognostic factor, is an interesting issue that requires further study. 相似文献

BACKGROUND: Malignant tumors of the skull base are rare. Therefore, no single center treats enough patients to accumulate significant numbers for meaningful analysis of outcomes after craniofacial surgery (CFS). The current report was based on a large cohort that was analyzed retrospectively by an International Collaborative Study Group. METHODS: One thousand three hundred seven patients who underwent CFS in 17 institutions were analyzable for outcome. The median age was 54 years (range, 1-98 years). Definitive treatment prior to CFS had been administered in 59% of patients and included radiotherapy in 367 patients (28%), chemotherapy in 151 patients (12%), and surgery in 523 patients (40%). The majority of tumors (87%) involved the anterior cranial fossa. Squamous cell carcinoma (29%) and adenocarcinoma (16%) were the most common histologic types. The margins of surgical resection were reported close/positive in 412 patients (32%). Adjuvant postoperative radiotherapy was received by 510 patients (39%), and chemotherapy was received by 57 patients (4%). RESULTS: Postoperative complications were reported in 433 patients (33%), with local wound complications the most common (18%). The postoperative mortality rate was 4%. With a median follow-up of 25 months, the 5-year overall, disease-specific, and recurrence-free survival rates were 54%, 60%, and 53%, respectively. The histology of the primary tumor, its intracranial extent, and the status of surgical margins were independent predictors of overall, disease-specific, and recurrence-free survival on multivariate analysis. CONCLUSIONS: CFS is a safe and effective treatment option for patients with malignant tumors of the skull base. The histology of the primary tumor, its intracranial extent, and the status of surgical margins are independent determinants of outcome. 相似文献

Preclinical evidence suggests that continuous low-dose daily (metronomic) chemotherapy may inhibit tumor endothelial cell proliferation (angiogenesis) and prevent tumor growth. This phase II study evaluated the feasibility of this antiangiogenic chemotherapy regimen in adults with recurrent malignant gliomas. The regimen consisted of low-dose etoposide (35 mg/m2 [maximum, 100 mg/day] daily for 21 days), alternating every 21 days with cyclophosphamide (2 mg/kg [maximum, 100 mg/day] daily for 21 days), in combination with daily thalidomide and celecoxib, in adult patients with recurrent malignant gliomas. Serum and urine samples were collected for measurement of angiogenic peptides. Forty-eight patients were enrolled (15 female, 33 male). Twenty-eight patients had glioblastoma multiforme (GBMs), and 20 had anaplastic gliomas (AGs). Median age was 53 years (range, 33-74 years), and median KPS was 70 (range, 60-100). Therapy was reasonably well tolerated in this heavily pretreated population. Two percent of patients had partial response, 9% had a minor response, 59% had stable disease, and 30% had progressive disease. For GBM patients, median progression-free survival (PFS) was 11 weeks, six-month PFS (6M-PFS) was 9%, and median overall survival (OS) was 21 weeks. For AG patients, median PFS was 14 weeks, 6M-PFS was 26%, and median OS was 41.5 weeks. In a limited subset of patients, serum and urine angiogenic peptides did not correlate with response or survival (p > 0.05). Although there were some responders, this four-drug, oral metronomic regimen did not significantly improve OS in this heavily pretreated group of patients who were generally not eligible for conventional protocols. While metronomic chemotherapy may not be useful in patients with advanced disease, further studies using metronomic chemotherapy combined with more potent antiangiogenic agents in patients with less advanced disease may be warranted. 相似文献
