BACKGROUND: A Phase II trial comprising patients with metastatic uveal melanoma (Stage IVB) was undertaken to determine the activity of bleomycin, vincristine, lomustine, and dacarbazine (BOLD) chemotherapy with human leukocyte interferon, as well as the progression-free and overall survival of the patients according to the substage before treatment. METHODS: Twenty-two patients with histologically proven metastatic uveal melanoma received 15 mg of bleomycin (Days 2 and 5), 1 mg/m(2) vincristine (Days 1 and 4), 200 mg/m(2) dacarbazine (Days 1 to 5), and 80 mg lomustine (Day 1) every 4 weeks together with a leukocyte interferon preparation (3 x 10(6) IU daily for 6 weeks followed by 6 x 10(6) IU three times per week). RESULTS: Of 20 evaluable patients, 3 (15%; 95% confidence interval [CI] 0-38) obtained a partial objective response in hepatic and extrahepatic sites and 11 (55%; 95% CI 32-77) showed stable disease after receiving more than two cycles. The median progression-free survival was 4 months (95% CI 2-10) and the median overall survival was 12 months (95% CI 8-22). Eleven patients who had favorable pretreatment characteristics (Stage IVBa) survived a median of 17 months (95% CI 4-37) whereas 10 patients with less favorable characteristics (Stage IVBb) survived a median of 11 months (95% CI 1-23). Moderate toxicity occurred with this outpatient regimen. CONCLUSIONS: The BOLD/human leukocyte interferon regimen had modest activity against metastatic uveal melanoma in hepatic and extrahepatic sites. The median overall survival approached that reported for more aggressive intrahepatic therapy regimens. Substage differences can significantly impact study outcomes. Therefore, substage information should be reported to facilitate comparisons between studies.  相似文献

Uveal melanoma metastases develop in 6.5-35% of patients, most commonly to the liver. Metastatic uveal melanoma (MUM) survival is poor, with 5-7 months of median survival. We reviewed retrospectively all patients with MUM diagnosed between January 1990 and December 2008 at our institution. We analyzed a total of 58 patients with a median age of 61 years (31-84 years). Median time for metastases development was 25.63 months (0.17-102.43 months). Fifty-six patients had hepatic involvement, 63.8% bilobar and 51.7% had more than or equal to five hepatic metastatic lesions. Sixteen patients (27.6%) had two or more organs involved. Six patients (10.71%) were treated with surgery, 25 patients (44.67%) received systemic chemotherapy, and 23 (41.07%) had best supportive care (BSC). The median overall survival (OS) for all the patients was 10.83 months [95% confidence interval (CI): 6.92-14.74]. Patients who had undergone chemotherapy presented 10.83 months (95% CI: 5.35-16.308) of median OS whereas the patients who did not undergo this treatment had an OS of 8.033 months (95% CI: 2.46-13.61). There were more patients with poor survival characteristics such as worse Eastern Cooperative Oncology Group performance status in the BSC group. OS was poor in treated and BSC patients. Differences in survival are more likely to be related to patient characteristics rather than to a chemotherapy effect. Patients with MUM should be included in clinical trials evaluating other options with newer agents.  相似文献

BACKGROUND: Exclusive liver metastases occur in up to 40% of patients with uveal melanoma associated with a median survival of 2-7 months. Single agent response rates with commonly available chemotherapy are below 10%. We have investigated the use of fotemustine via direct intra-arterial hepatic (i.a.h.) administration in patients with uveal melanoma metastases. PATIENTS AND METHODS: A total of 101 patients from seven centers were treated with i.a.h. fotemustine, administered intra-arterially weekly for a 4-week induction period, and then as a maintenance treatment every 3 weeks until disease progression, unacceptable toxicity or patient refusal. RESULTS: A median of eight fotemustine infusions per patient were delivered (range 1-26). Catheter related complications occurred in 23% of patients; however, this required treatment discontinuation in only 10% of the patients. The overall response rate was 36% with a median overall survival of 15 months and a 2-year survival rate of 29%. LDH, time between diagnosis and treatment start and gender were significant predictors of survival. CONCLUSIONS: Locoregional treatment with fotemustine is well tolerated and seems to improve outcome of this poor prognosis patient population. Median survival rates are among the longest reported and one-third of the patients are still alive at 2 years.  相似文献

Uveal melanoma is the most common primary intraocular tumour in adults. After treatment of the primary tumour, up to 50% of patients will ultimately develop metastases. Treatment options for metastases are limited. When uveal melanoma metastases are confined to the liver, isolated hepatic perfusion (IHP) could be a treatment option. Herein, we report the results of a small group of patients with uveal melanoma metastases of the liver treated with IHP. Eight patients with uveal melanoma metastases confined to the liver underwent IHP with high-dose melphalan (200 mg) for 1 h. Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria and tumour response was assessed according to World Health Organization criteria. The tumour response rate (complete or partial remission) was 50%. The median time to progression was 6.7 months (range, 1.7-16.9 months). The overall median survival was 9.9 months (range, 4.7-34.6 months), with a 1 year survival of 50% and a 2 year survival of 37.5%. Three patients experienced grade 3-4 hepatotoxicity which was transient within 3 months. Although only a small group of patients has been treated and evaluated so far, IHP is a treatment option for uveal melanoma metastases confined to the liver which can result in tumour responses and may lead to survival benefits in a selective group of patients.  相似文献

Uveal melanoma is the most common primary intraocular malignancy in adults and the liver is the most common site for systemic metastases. We conducted a phase II clinical trial for patients with hepatic metastases from uveal melanoma using chemoembolization of the hepatic artery with 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) dissolved in ethiodized oil. Gelatin sponge particles were used as a transiently occlusive agent. The responses in hepatic metastases, overall survival, time to progression and side-effects related to chemoembolization were evaluated. Thirty patients were enrolled. Twenty-four patients completed at least one treatment to all targeted liver metastases and were evaluable for hepatic response. Eighteen of these 24 patients experienced regression or stabilization of hepatic metastases for at least 6 weeks (one complete response in hepatic metastases; four partial responses; 13 stable disease). One of the 13 patients with stable disease was rendered free of disease by surgical removal of metastases after chemoembolization (surgical complete response). The overall response rates (complete and partial responses) for intention-to-treat patients and for patients who were evaluable for response were 16.7 and 20.4%, respectively. The median overall survival of the entire intention-to-treat group of patients was 5.2 months (range, 0.1-27.6 months), for patients with complete or partial response in hepatic metastases 21.9 months (range, 7.4-27.6 months), for patients with stable disease 8.7 months (range, 2.9-14.4 months) and for patients with progressive disease 3.3 months (range, 1.6-5.6 months). Importantly, 13 of the 18 patients who achieved complete response, partial response or stable disease subsequently developed progression of extrahepatic metastases with control of hepatic metastases. Chemoembolization with BCNU is a useful palliative treatment for the control of hepatic metastases in uveal melanoma patients. However, progression in extrahepatic sites after stabilization of hepatic metastases requires further improvement in the therapeutic approach to this disease.  相似文献

Background. Uveal melanoma is characterized by a high frequency of hepatic metastases. For patients with liver metastases, who have a median survival of 5 to 7 months, surgery and systemic conventional chemotherapy have little to offer. Methods. Between February 1995 and July 1999, seven patients with isolated hepatic metastases from uveal melanoma were enrolled into a pilot trial of intraarterial fotemustine therapy. An implantable Port-A-Cath catheter was inserted into the hepatic artery for regional chemotherapy via the gastroduodenal artery. Fotemustine 100 mg/m2 was administered intraarterially over a 4-h period. The induction phase consisted of one administration per week for 4 weeks, followed by a 5-week rest period. Maintenance therapy with administration of fotemustine every 3 weeks continued until progression or toxicity. Results. Ten patients were evaluated for the trial. One patient was not eligible because of impaired liver function, and in two patients implantation of the port system was not possible for anatomic reasons. Seven patients received a median of 16 treatment cycles (range, 4–28) and all were evaluable for response. Two patients achieved a partial response (PR), three had stable disease (SD), and tumor progressed in two patients (PD). The median survival time from diagnosis of liver metastasis was 24 months (range, 4 to 50+ months). Two patients survived for more than 2 years and two patients are still alive. The toxicity was low and the treatment could be administered on an outpatient basis. Conclusion. Intraarterial fotemustine treatment of uveal melanoma metastatic to the liver is well tolerated, and in some patients is associated with prolonged survival.

OBJECTIVES: The number of agents that are active in patients with metastatic melanoma is limited and cure is not a realistic objective for treatment at this stage. The aim of the study was to evaluate the efficacy and safety of new combination regimen cosisting of docetaxel and dacarbazine (DTIC), as first-line chemotherapy, in patients with advanced melanoma. PATIENTS AND METHODS: Patients with advanced melanoma (including cerebral metastases) were eligible. Docetaxel 80 mg/m(2), i.v. over 1 h infusion on day 1, and DTIC 400 mg/m(2), i.v. over 45 min on days 1 and 2, were given every 21 days, for six cycles. All patients were premedicated, prior to each course, with methylprednisolone per os. RESULTS: Forty-one patients entered the study. Thirty-nine were assessable for response and 40 for toxicity. Objective responses were seen in 10 patients (24% of the eligible; 95% CI = 12.4-40.3%, 26% of the assessable and 28% of patients with cerebral metastases were excluded). Three of them achieved a complete response (7%; 95% CI = 1.5-19.9) and 7 a partial response (17%; 95% CI = 7.1-32.0), while 8 patients demonstrated stabilization of their disease (20%; 95% CI = 8.8-34.9). After a median follow-up of 20 months, the median time to progression was 7 months (range 0.5-22) and the median survival was 10 months (1-24+). The main toxicity (G3-4) was neutropenia which occurred in 8/40 (20%) patients. Additional patients had reversible G3-4 toxicities including alopecia, nausea and vomiting and fatigue; 3 of them presented mild to moderate hypersensitivity reactions to docetaxel. No toxic death was noted. CONCLUSIONS: The combination of docetaxel and DTIC is active and well tolerated in patients with advanced melanoma. While this combination is at least as effective as various combination regimens, it does not differ from that reported for single-agent DTIC.  相似文献

Uveal melanoma is relatively uncommon accounting for fewer than 5% of all melanoma cases. Localized tumours are curable by local therapy but a significant percentage of patients go on to have a relapse with metastatic disease. Uncertainty remains concerning the level of activity of dacarbazine in uveal melanoma as opposed to that in the cutaneous form. Recently, a possible role for treosulfan in uveal disease has been reported. A phase II study was therefore undertaken to assess the objective response rate of the combination of dacarbazine and treosulfan in previously untreated patients with metastatic uveal melanoma. All patients received dacarbazine 850 mg/m and treosulfan 8 g/m(2) every 21 days up to a maximum of six cycles. Fifteen patients enrolled in the study. As expected, the major toxicities were haematological (particularly thrombocytopaenia) but the treatment was generally well tolerated. No responses were seen; however, disease stabilization was achieved in two patients. Median progression free survival from the start of chemotherapy was 12 weeks and median overall survival was 30 weeks. This study, using the combination of dacarbazine and treosulfan, while well tolerated, did not confirm earlier reports suggesting treosulfan is active in uveal melanoma.  相似文献

This EORTC multicentre study analysed the efficacy and tolerability in patients with metastatic uveal melanoma of BOLD chemotherapy in combination with recombinant interferon alpha-2b. The dose of bleomycin was 15 mg on days 2 and 5, of vincristine 1 mg/m(2) on days 1 and 4, of lomustine 80 mg on day 1, and of dacarbazine (DTIC) 200 mg/m(2) on days 1-5, given every 4 weeks for a minimum of two cycles. Subcutaneous (s.c.) interferon alpha-2b at a dose of 3 x 10(6) IU was initiated on day 8 of the first cycle, and continued at a dose of 6 x 10(6) IU three times per week after 6 weeks. A median of two cycles were administered to 24 patients (median age 60.5 years). None achieved an objective response (0%; 95% Confidence Interval (CI): 0-14), 2 (8.3%) remained stable, 20 showed progression, and 2 (8.3%) were invaluable. The median progression-free survival was 1.9 months (95% CI: 1.8-3.4) and overall survival 10.6 months (95% CI: 6.9-16.4). Overall survival improved with increasingly favourable pretreatment characteristics (median, 14.7 versus 6.9 versus 6.0 months for Helsinki University Central Hospital (HUCH) Working Formulation stages IVBa, IVBb and IVBc, respectively; P=0.018). Grade 3 alopecia and neurotoxicity occurred in 13% of the patients. This multicentre study did not confirm earlier reports that BOLD with human leucocyte or recombinant interferon would induce at least 15% objective responses in metastatic uveal melanoma.  相似文献

BackgroundAfter treatment of primary ocular uveal melanoma (UM), up to 50% of patients will develop metastases, mostly in the liver. Systemic treatments do not provide any overall survival benefit for these patients and surgery remains the most effective therapy for selected patients. Radiofrequency ablation (RFA) alone or in combination with surgery is frequently used to spare hepatic parenchyma. When patients relapse after treatment of their first metastases, and when the liver recurrence is limited, new local liver treatment is questionable.MethodsA total of 14 patients with liver metastases from uveal melanoma (LMUM) were retrospectively evaluated. All patients had a complete first liver resection and a second treatment with RFA. Overall survival, recurrence-free interval after the first and the second treatment was evaluated.ResultsTreatment of hepatic recurrence was percutaneous RFA for ten patients and per-operative RFA for four patients associated with new metastasectomy. The median time to onset of LMUMs after ocular UM treatment was 50 months, and the median time to recurrence of hepatic metastasis after the first liver treatment was 20 months. The overall survival was 70% at five years and 35% at ten years. The recurrence-free interval was 50% and 56% at two years after the first and the second treatment, respectively.ConclusionProlonged survival can be achieved by exclusive and iterative local treatment combining surgery and RFA in a small proportion of patients with a first recurrence of isolated LMUM.  相似文献

There are no satisfactory treatment options for patients with ocular melanoma metastatic to liver, and after liver metastases are identified, median survival is only between 2 and 7 months. Because liver metastases are the sole or life-limiting component of disease in the vast majority of patients who recur, we reasoned that complete vascular isolation and perfusion of the liver might result in clinically meaningful regression of disease. Between September 1994 and July 1999, 22 patients (13 women and 9 men; mean age, 49 years) with ocular melanoma metastatic to liver were treated with a 60-min hyperthermic isolated hepatic perfusion (IHP) using melphalan alone (1.5-2.5 mg/kg, n = 11) or with tumor necrosis factor (TNF, 1.0 mg, n = 11). Via a laparotomy, IHP inflow was via the hepatic artery alone (n = 17) or hepatic artery and portal vein (n = 5) and outflow from an isolated segment of inferior vena cava. Most patients had advanced tumor burden with a mean percentage of hepatic replacement of 25% (range, 10-75%) and a median number of metastatic nodules of 25 (range, 5 to >50). Complete vascular isolation was confirmed in all patients using a continuous intraoperative leak monitoring technique with 131I radiolabeled albumin. There was one treatment mortality (5%). The overall response rate in 21 patients was 62% including 2 radiographic complete responses (9.5%) and 11 partial responses (52%). The overall median duration of response was 9 months (range, 5-50) and was significantly longer in those treated with TNF than without (14 versus 6 months, respectively; P = 0.04). Overall median survival in 22 patients was 11 months. These data indicate that a single 60-min IHP can result in significant regression of advanced hepatic metastases from ocular melanoma. TNF appears to significantly prolong the duration of response.  相似文献

Background & AimBrain metastases are frequent in patients with metastatic melanoma, indicating poor prognosis. We investigated the BRAF kinase inhibitor vemurafenib in patients with advanced melanoma with symptomatic brain metastases.MethodsThis open-label trial assessed vemurafenib (960 mg twice a day) in patients with BRAFV600 mutation-positive metastatic melanoma with non-resectable, previously treated brain metastases. The primary end-point was safety. Secondary end-points included best overall response rate, and progression-free and overall survival.ResultsTwenty-four patients received vemurafenib for a median treatment duration of 3.8 (0.1–11.3) months. The majority of discontinuations were due to disease progression (n = 22). Twenty-three of 24 patients reported at least one adverse event (AE). Grade 3 AEs were reported in four (17%; 95% confidence interval [CI], 4.7–37.4%) patients and included cutaneous squamous cell carcinoma in four patients. Median progression-free survival was 3.9 (95% CI, 3.0–5.5) months, and median survival was 5.3 (95% CI, 3.9–6.6) months. An overall partial response (PR) at both intracranial and extracranial sites was achieved in 10 of 24 (42%; 95% CI, 22.1–63.4) evaluable patients, with stable disease in nine (38%; 95% CI, 18.8–59.4) patients. Of 19 patients with measurable intracranial disease, seven (37%) achieved >30% intracranial tumour regression, and three (16%; 95% CI, 3.4–39.6%) achieved a confirmed PR. Other signs of improvement included reduced need for corticosteroids and enhanced performance status.ConclusionsVemurafenib can be safely used in patients with advanced symptomatic melanoma that has metastasised to the brain and can result in meaningful tumour regression.  相似文献

Malignant melanoma of the uvea is remarkable for purely haematogenous dissemination and its tendency to metastasise to the liver. Although the liver is involved in up to 95% of patients, 50% of these also develop extrahepatic metastases, most often in the lungs, bone, skin, and brain. The only effective treatments reported to date relied on hepatic arterial chemoembolisation or -perfusion. The objective of this study was to establish a therapy protocol addressing patients with both sole liver involvement and systemic disease. Forty-eight patients with metastatic ocular melanoma received fotemustine 100 mg m(-2) either as 60-min infusion into the hepatic artery or as 15-min infusion via a peripheral vein, depending on the metastatic sites involved, i.e., restriction to the liver or hepatic together with extrahepatic disease. For the first treatment cycle this infusion was repeated after one week. For all cycles, subsequent to a three week resting period, patients received an immunotherapy consisting of subcutaneous interleukin 2 and interferon alpha(2). Although objective responses were more frequent within the cohort receiving intraarterial fotemustine (21.7 vs 8%), this difference did not translate into a significant benefit in overall survival, i.e., 369 and 349 days, respectively. Of note, this overall survival is much longer than that repeatedly reported for stage IV uveal melanoma not treated with fotemustine, suggesting a therapeutic activity of this cytostatic drug even after systemic administration.  相似文献

BACKGROUND: Single-agent chemotherapy with dacarbazine continues to be the standard of care for the treatment of metastatic melanoma. However, there is a large population of patients who have failed first-line therapy and might benefit from additional treatment. In the current study, the authors evaluated the antitumor effects and toxicity of vinorelbine therapy in patients who had failed one prior systemic therapy. METHODS: Patients were required to have a histologic diagnosis of melanoma and be of Stage IV with measurable disease, a Southwest Oncology Group (SWOG) performance status (PS) of 0-2, no evidence of brain metastases, and adequate bone marrow and liver function. Treatment was comprised of vinorelbine given at a dose of 30 mg/m(2)/week by intravenous bolus. RESULTS: Twenty-four patients were registered to the study, 3 of whom were determined to be ineligible. The 21 eligible patients had a median age of 58 years with a SWOG PS of 0 in 7 patients, 1 in 13 patients, and 2 in 1 patient. There were no complete or partial responses observed, for a response rate of 0 of the 21 patients studied (95% confidence interval [95% CI], 0-16%); the study closed after the first stage of accrual. The estimated median progression-free survival was 2 months (95% CI, 1.5-3.3 months) and the estimated median overall survival was 6 months (95% CI, 3.7-8.3 months). There was one death due to febrile neutropenia reported, with six patients experiencing one or more Grade 4 toxicities, including neutropenia/granulocytopenia, leukopenia, dyspnea, and fatigue. CONCLUSIONS: Despite impressive preclinical activity against melanoma, vinorelbine does not appear to have enough clinical activity to be of interest in previously treated patients with disseminated melanoma. The progression-free and overall survival results noted in previously treated patients in the current study were similar to results reported in prior SWOG Phase II trials in untreated patients. The group of previously treated patients may be used to evaluate new agents for the treatment of disseminated melanoma.  相似文献

Docosahexaenoic acid (DHA)-paclitaxel is a taxane with a unique pharmacokinetic profile. We investigated the safety and response rate of DHA-paclitaxel weekly in patients with metastatic uveal melanoma. Chemotherapy-naive and previously treated patients were eligible for this open-label phase II study. DHA-paclitaxel (500?mg/m2/week) was administered by a 1-hour intravenous infusion for five consecutive weeks in a 6-weeks cycle. Response was assessed using the Response Evaluation Criteria in Solid Tumors every 6 weeks. Twenty-two patients were enrolled. The patients' median age was 56 years (range: 33-79 years). Nine patients had a systemic therapy for metastatic disease earlier. The median number of treatment cycles was 1 (range 1-7 cycles). One chemonaive patient with liver metastases had partial response lasting for 5 months. Seven patients (32%) had stable disease with a median duration of 3 months (range: 3-7 months). The median overall survival was 9.8 months. Neutropenia (23%) and musculoskeletal pain (10%) were the most common grade 3 and grade 4 toxicities. As a single-agent therapy, DHA-paclitaxel is safe and well-tolerated in metastatic uveal melanoma patients. Its efficacy in this disease is limited with 32% of patients achieving stable disease. Further evaluation of DHA-paclitaxel in combination with other chemotherapeutic agents and/or targeted agents may improve its antitumor activity.  相似文献

The aim of this study was to evaluate the efficacy and toxicity of ifosfamide, 5-fluorouracil (5-FU) and leucovorin (IFL) as a second-line chemotherapy regimen in patients with recurrent undifferentiated nasopharyngeal carcinoma (NPC) previously treated with platinum/5-FU. Between June 1997 and February 1999, 18 patients were entered into the study. 3 patients had loco-regional recurrence, 12 had distant metastases and 3 had both loco-regional recurrence and distant metastases. All patients had previously received platinum/5-FU as adjuvant or palliative treatments. The IFL regimen consisting of ifosfamide 1.2 g/m(2) (with mesna), 5-FU 375 mg/m(2) and leucovorin 20 mg/m(2) for 5 days and was repeated every 21 days. The dose of ifosfamide was escalated to 1.4 and 1.6 g/m(2) in subsequent cycles according to the bone marrow toxicity, and the dose of 5-FU to 450 and 525 mg/m(2) according to the severity of mucositis. Patients received a median of 3 cycles of IFL (range: 2-6), with a median total ifosfamide dose of 21 g/m(2) (range: 13-46) and a median total 5-FU dose of 6.75 g/m(2) (range: 4.1-14.7). The median follow-up was 10 months (range: 4-25). 9 patients (50%) achieved a partial response and 1 patient (6%) achieved a complete response, with an overall response rate of 56% (95% confidence interval (CI): 32-80%). For those patients who responded to IFL, 8 had subsequent disease progression on follow-up, with a median response duration of 7.1 months (95% CI: 5.3-8.9). The median time to progression for all patients was 6.5 months (95% CI: 4.2-8.7). 12 patients are still alive with an estimated 1-year survival probability rate of 51%. Treatments were well tolerated, only 1 patient had grade 3 emesis. None of the patients had grade 3/4 anaemia, leucopenia or thrombocytopenia, although IFL was discontinued in 1 patient because of persisting thrombocytopenia. IFL is an effective second-line regimen in patients with recurrent NPC and is well tolerated with mild toxicity. Combining platinum and IFL in chemona?ve patients may further improve the overall response rate and duration and is worth investigating in future trials.  相似文献

BACKGROUND: The 1997 staging system for esophageal carcinoma subdivided distant metastatic disease (M1) into nonregional lymph node metastases (M1a) and other metastases (M1b). To determine the relevance of this classification system, we investigated the efficacy and toxicity of capecitabine/cisplatin (XP) chemotherapy alone or in combination with radiotherapy. METHODS: We identified 74 patients with M1 disease treated at Asan Medical Center from January 2003 to December 2005. Of these patients, 19 (25.7%) were classified as M1a, 29 (39.2%) as M1b (nonvisceral lymph node metastases), and 26 (35.1%) as M1b (visceral metastases). All patients were treated with first two cycles of XP induction chemotherapy, consisting of capecitabine 1000 mg/m(2) twice daily on days 1-14, and i.v. cisplatin 60 mg/m(2) on day 1, every 3 weeks. Patients classified as M1a and M1b (nonvisceral lymph node metastases) were treated with 54 Gy of radiotherapy, concurrently with weekly capecitabine 800 mg/m(2) twice daily on days 1-5 and i.v. cisplatin 30 mg/m(2) on day 1 during radiation. Patients classified as M1b (visceral metastases) were treated with chemotherapy only until disease progression or intolerance to chemotherapy. RESULTS: In response to the first two cycles of chemotherapy, 3/18 (16.7%) M1a nonregional lymph node (LN), 4/27 (14.8%) M1b nonvisceral LN metastases and 5/25 (20%) M1b visceral metastases patients attained partial responses. After definitive chemoradiation in the setting of M1a, M1b nonvisceral LN metastases and maximum cycles of chemotherapy in the M1b visceral metastases setting, the response rates were 77.8, 62.9 and 36.0% respectively. With median follow-up of 12.5 months (range 0.5-22.8), 50 of 74 patients (67.5%) died. The median time to progression (TTP) was 7.8 months (95% CI, 6.0-9.5 months) and the median overall survival (OS) was 12.0 months (95% CI, 9.0-15.0 months). Median TTP in the M1a, M1b nonvisceral LN metastases and M1b visceral metastases were 10.3, 6.5 and 5.9 months, respectively (P = 0.087), whereas median OS in these groups was 13.8, 13.8, and 8.2 months, respectively (P = 0.134). Median TTP was 8.4 months (95% CI, 5.5-11.3 months) in the 48 patients with M1a and M1b nonvisceral LN metastases and 5.9 months (95% CI, 2.7-9.0 months) in the 26 patients with M1b visceral metastases (P = 0.03), and median OS in these two groups was 13.8 months (95% CI, 10.4-17.3 months) and 8.2 months (95% CI, 5.7-10.7 months), respectively (P = 0.04). CONCLUSION: The similar OS in patients with M1a and M1b nonvisceral LN metastases suggests that concurrent chemoradiotherapy might contribute in the latter. Our findings indicate that sequentially combined chemoradiotherapy containing XP regimen was active and well tolerated as first-line treatment for M1a as well as M1b esophageal cancer.  相似文献

Gemcitabine plus treosulfan (GeT) is under investigation in metastatic uveal melanoma. In this phase II trial, cisplatin was added to a GeT regimen to investigate the efficacy and toxicity of two alkylating agents in combination with gemcitabine. Patients received 30 or 40 mg/m of cisplatin, 1000 mg/m of gemcitabine and 3000 mg/m of treosulfan on days 1 and 8. Therapy was repeated on day 29. A maximum of six cycles was administered. Nineteen patients were included in the trial, of whom 17 were evaluable for response. No objective response was observed; seven patients (41%) had stable disease and 10 (59%) progressed. The median progression-free survival of all 19 patients was 3.0 months [95% confidence interval (CI), 1.8-3.1]; the median overall survival was 7.7 months (95% CI, 1.9-13.8). Grade 3 and 4 thrombopenia and leucopenia occurred in eight and nine of the 19 patients, respectively. The addition of cisplatin to the GeT regimen results in excessive haematological toxicity without improvement in efficacy.  相似文献

BACKGROUND: Temozolomide and interferon-alpha-2b (IFN-alpha-2b) are both active in melanoma. Therefore, the efficacy and safety of temozolomide in combination with pegylated IFN-alpha-2b in patients with metastatic melanoma without brain metastases was investigated. METHODS: Patients with histologically confirmed, unresectable, American Joint Committee on Cancer Stage IV melanoma were enrolled in an open-label, Phase II study. The primary endpoints were tumor response and safety. Patients received temozolomide (75 mg/m2/dayx6 weeks with a 2-week break between cycles) plus concomitant subcutaneous pegylated IFN-alpha-2b (0.5 microg/kg/wk, continuously). Treatment was continued until unacceptable toxicity or disease progression occurred. RESULTS: Thirty-five patients (median age, 55 years) with Stage IV melanoma and a median of 3 metastatic sites were enrolled and received a median of 1 cycle (i.e., 8 weeks) of therapy (range, 0-6 cycles). Eleven patients (31%) (95% confidence interval, 16% to 47%) had an objective tumor response, including 3 with clinical complete response durations of 6 months, 20 months, and 32+ months and 8 with partial responses. Three patients with a partial or mixed response were subsequently rendered free of clinically detectable disease with surgery. The median survival was 12 months with a median follow-up among survivors of 16 months. No patient developed brain metastases while receiving study treatment. Treatment was generally well tolerated. Hematologic toxicity consisted mainly of lymphopenia and leukopenia (National Cancer Institute Common Toxicity Criteria Grades 1-3); no Grade 4 hematologic toxicity was observed. CONCLUSIONS: The combination of temozolomide plus pegylated IFN-alpha-2b had antitumor activity and was well tolerated in patients with metastatic melanoma. Therefore, further study is warranted.  相似文献

OBJECTIVES: This phase II study was conducted to evaluate the efficacy and safety of gemcitabine in patients with metastatic breast cancer (MBC). METHODS: Women with histologically or cytologically confirmed bidimensionally measurable MBC not amendable to curative surgery or radiation were eligible. Prior chemotherapy for metastatic disease was not permitted. Patients received gemcitabine 1,200 mg/m(2) on days 1, 8 and 15 for 3 weeks every 28 days for a maximum of 8 cycles. RESULTS: Thirty-nine patients, with a median age of 58 years, were enrolled. The overall response rate for the 35 evaluable patients was 37.1% (95% confidence interval [CI], 21.5-55.1%), with 2 complete responses and 11 partial responses. Median time to progression and survival were 5.1 months (95% CI, 3.5-8.8 months) and 21.1 months (95% CI, 11.0-26.9 months), respectively. Chemotherapy was well tolerated, with a median of 4 cycles completed. Grade 4 toxicities were 1 infection and 1 abnormal pulmonary function. Grade 3 neutropenia and thrombocytopenia occurred in 30.3% and 6.3% of patients, respectively. The most common grade 3 non-hematologic toxicity was nausea/vomiting (10.3%). Five of 21 patients had improved Karnofsky performance status (KPS) scores. CONCLUSION: Single-agent gemcitabine is active and well tolerated as first-line treatment in patients with MBC.  相似文献
