A phase II trial of modified FOLFOX as first-line chemotherapy in advanced colorectal cancer

The objective was to evaluate the efficacy and toxicity of leucovorin plus 5-fluorouracil combined with oxaliplatin (modified FOLFOX regimen) every 2 weeks on previously untreated advanced colorectal cancer patients in the Chinese population. Fifty-one inpatients were enrolled to receive 85 mg/m oxaliplatin intravenously over a 2- h period on day 1, together with 400 mg/m2 leucovorin over 2- h, followed by a 46-h infusion of 5-fluorouracil at 2600 mg/m2 every 2 weeks. Treatment was given until progression or unmanageable toxicity ensued. In all, 51 patients received three or more oxaliplatin doses and a median of nine treatment cycles (range 3-16 cycles). Of the 51 eligible patients, two complete responses and 22 partial responses were observed for an overall response rate of 47.0% (95% confidence interval 35-64%). Median progression-free survival was 7.7 months (95% confidence interval 6.8-8.6) and median overall survival was 15.0 months (95% confidence interval 13.1-16.9). Toxicities were mild: five patients (9.8%) reported grade 3-4 neutropenia, 33 patients (64.8%) experienced grade 1-3 neurotoxicity and only six patients (11.8%) experienced grade 3 neurotoxicity. The leucovorin plus 5-fluorouracil combined with oxaliplatin (modified FOLFOX) regimen is active and well tolerated in patients with previously untreated advanced colorectal cancer in the Chinese population.     

A phase II study of modified FOLFOX as first-line chemotherapy in advanced small bowel adenocarcinoma

This study aimed at assessing the efficacy and safety of biweekly oxaliplatin in combination with continuous infusional 5-fluorouracil and leucovorin (modified FOLFOX regimen) in patients with advanced small bowel adenocarcinoma (SBA). Thirty-three eligible patients with previously untreated SBA received 85 mg/m(2) of oxaliplatin intravenously over a 2-h period on day 1, together with 400 mg/m(2) of leucovorin over 2 h, followed by a 46-h infusion of 5-FU 2600 mg/m(2) every 2 weeks. All patients were evaluable for efficacy and toxicity. A median of nine cycles (range 3-18) was administered. The objective response rate was 48.5% [95% confidence interval (95% CI): 31-67%], with one complete response, 15 partial responses, 12 stable diseases, and five progressions. The median time to progression was 7.8 months (95% CI: 6.0-9.6) and the median overall survival was 15.2 months (95% CI: 11.0-19.4). Toxicity was fairly mild. Grade 3 toxicities included neutropenia (12.1%), thrombocytopenia (3.0%), nausea (6.1%), vomiting (3.0%), diarrhea (3.0%), peripheral neuropathy (9.1%), and fatigue (3.0%), and grade 4 toxicities occurred in none of the patients. The modified FOLFOX regimen is highly active and well tolerated as first-line chemotherapy for advanced SBA patients.

A phase II study of an oxaliplatin/vinorelbine/5-fluorouracil combination in patients with anthracycline-pretreated and taxane-pretreated metastatic breast cancer

The aim of this phase II study was to evaluate safety and efficacy of an oxaliplatin/vinorelbine/5-fluorouracil (FON) combination in anthracycline and taxane-pretreated metastatic breast cancer patients. The following treatment was given: on day 1 of a 21-day cycle, oxaliplatin 130 mg/m (2-h intravenous infusion); on days 1 and 5, vinorelbine [dose level (DL) 1: 17.5 mg/m; DL2: 22 mg/m]; on days 1-5, continuous infusion 5-fluorouracil (DL1: 600 mg/m/day; DL2: 750 mg/m/day). Forty-seven patients were treated (DL1: 43; DL2: 4). Median age was 54 years; 68% had liver metastases, 53% were taxane refractory/resistant and 38% were anthracycline refractory/resistant. Patients received a median of six treatment cycles. Of 46 eligible patients, 16 had partial response; the overall response rate was 34.8% (95% confidence interval 21.3-50.3%), 11 had stable disease lasting more than 4 months. Median follow-up was 13.0 months, median time to progression 5.7 months and estimated overall survival 18.8 months. DL2 was too toxic with three patients having grade 3-4 toxicity, including one death. At DL1, 26 patients (60%) experienced grade 3-4 neutropenia (six febrile neutropenia) and eight had grade 3 oxaliplatin-specific peripheral neuropathy after a median of 646.4 mg/m oxaliplatin (range 124-1619 mg/m). Oxaliplatin (130 mg/m, day 1)/vinorelbine (17.5 mg/m, days 1,5)/5-fluorouracil (600 mg/m/day, days 1-5) demonstrate encouraging activity and a manageable safety profile in anthracycline- and taxane-pretreated metastatic breast cancer patients.     

Phase II trial of oxaliplatin combined with leucovorin and fluorouracil for recurrent/metastatic biliary tract carcinoma

Biliary tract carcinoma is often diagnosed at an advanced stage, and there is currently no established palliative standard of care. This phase II study investigated the efficacy and safety of combination chemotherapy of oxaliplatin, leucovorin, and 5-fluorouracil (5-FU) in biliary tract carcinoma. Patients with unresectable or recurrent biliary tract carcinoma were enrolled, including pretreated and chemotherapy-naive patients. Treatment consisted of intravenous oxaliplatin (100 mg/m2, day 1) followed by leucovorin (100 mg/m2, day 1) and 5-FU (1000 mg/m2, days 1 and 2). Treatment was repeated every 3 weeks. The efficacy and safety of the treatment were determined. Twenty-eight patients were evaluable, and a total of 166 cycles were administered (median five cycles). One complete response (3.6%) and five partial responses (17.9%) were noted, with a response rate of 21.5% [95% confidence interval (CI): 6.2-36.7], according to Response Evaluation Criteria in Solid Tumors criteria. The median time to progression and overall survival was 3.5 months (95% CI: 2.7-4.3) and 10.0 months (95% CI: 7.2-12.8), respectively. The 1-year survival rate was 17.8%. Grade 3/4 neutropenia and thrombocytopenia were recorded in 18 and 4% of the patients, respectively. No treatment-related death was observed. Oxaliplatin in combination with leucovorin and 5-FU should be considered a feasible chemotherapy regimen for patients with recurrent/metastatic biliary tract carcinoma.

UFT/leucovorin and mitomycin C as salvage treatment in patients with advanced colorectal cancer - a retrospective analysis

Active anticancer drugs and/or combination regimens for the treatment of patients failing oxaliplatin, irinotecan and 5-fluorouracil are desperately needed. In this analysis we describe the safety and efficacy of the combination of mitomycin C, UFT and leucovorin in such an extensively pretreated patient population. Between January 2002 and June 2004, a total of 41 patients were treated with mitomycin C (8 mg/m on day 1) and UFT (350 mg/m)+ leucovorin (90 mg) both divided into three daily doses from day 1 to day 14 every 4 weeks. All patients had failed prior first-line and second-line treatment with oxaliplatin, irinotecan and 5-fluorouracil. The aim of this retrospective analysis was to evaluate the efficacy and safety data of this potential salvage therapy regimen. Thirty-nine patients were evaluable for the response. The overall response rate (intent-to-treat) was 7.3% (95% confidence interval, 2.5-19.4%) and disease stabilization was achieved in 29.3%. Median time to progression was 2.5 months (range, 1.5-13.5) and median overall survival was 6 months (range, 1.5-26). Myelosuppression was the most frequent side effect. Grade 3 hematotoxicity, however, was observed in only three patients. The most common nonhematological toxicities consisted of mild and reversible nausea, emesis and diarrhea; again, severe symptoms were only occasionally seen. These data show that the combination of mitomycin C/UFT/leucovorin is safe and active in about one-third of patients in terms of abrogation of progression in extensively pretreated metastatic colorectal cancer.     

Weekly treatment with irinotecan, folinic acid and infusional 5-fluorouracil (ILF) in patients with advanced gastric cancer

Although 5-fluorouracil remains the mainstay of treatment for advanced gastric cancer (AGC), no standard chemotherapy regimen exists. Combinations of irinotecan with folinic acid and infusional 5-fluorouracil (5-FU) (ILF) have shown good efficacy with acceptable toxicity in patients with metastatic colorectal cancer. At present, only sparse data on ILF are available for AGC. Therefore we conducted a prospective study of this combination in 25 consecutive patients with metastatic gastric cancer. Median age was 63 years, 10 had received prior chemotherapy and 13 presented initially with peritoneal carcinosis. Treatment consisted of irinotecan 80 mg/m2, folinic acid 500 mg/m2 and infusional 5-FU 2.0 g/m2 over 24 h, given weekly for 6 weeks followed by a 1-week rest. Grade 3/4 hematologic toxicity occurred in six patients (anemia = 4, neutropenia = 1 and leukopenia = 1). Non-hematologic toxicity consisted mainly of nausea/vomiting (grade 3/4 in six patients) and diarrhea (grade 3/4 in 10 patients). The overall response rate was 20% for first- and second-line treatment, with two complete and three partial responses. Another nine patients (36%) had stable disease, for a tumor control rate of 56%. Median time to progression was 4 months, median overall survival and survival for patients with tumor control was 7 and 13 months, respectively. We conclude that ILF is a feasible outpatient regimen with manageable toxicity that provides tumor control in a high proportion of patients with advanced gastric cancer, even among those with unfavorable prognostic features.     

Multicenter phase II study of capecitabine plus oxaliplatin as a first-line therapy in Chinese patients with advanced gastric cancer

The efficacy of chemotherapy for advanced gastric cancer with palliative intent compared with supportive care alone is now widely accepted. However, the survival advantage is small, and no internationally accepted standard regimen has emerged. This study is performed to evaluate the response rate, time to progression, and safety of the combination of capecitabine (1000 mg/m twice daily, days 1-14) plus oxaliplatin (130 mg/m as a 2-h intravenous infusion on day 1) every 3 weeks, in previously untreated Chinese patients with advanced gastric cancer. Sixty-five (95.6%) of the 68 patients were assessable for response. Three cases of complete response and 34 cases of partial response were confirmed, giving an overall response rate of 54.4% [95% confidence interval (CI), 42.6-66.2%]. The median time to progression and overall survival for all patients were 5.7 months (95% CI, 2.0-8.8 months) and 10.5 months (95% CI, 5.0-15.1 months). The most severe hematologic adverse event was neutropenia, which occurred with grade 3 intensity in three (4.6%) patients and grade 4 in one (1.5%) patient. Thrombocytopenia and leukopenia occurred with grade 3 intensity in five (7.7%) and three (4.6%) patients, respectively. However, no grade 4 thrombocytopenia and leukopenia were observed. Grade 1/2 nausea/vomiting and diarrhea were observed in 33 (50.8%), 17 (26.2%), 26 (40%), 44 (67.7%), and 13 (20%) patients, respectively, and grade 3 nausea/vomiting and diarrhea were observed in one (1.5%) and four (6.2%) patients. Yet, no grade 4 nonhematologic toxicity was observed. Capecitabine/oxaliplatin combination chemotherapy is active in Chinese patients with previously untreated advanced gastric cancer.     

Mitomycin C plus S-1 as second-line therapy in patients with advanced gastric cancer: a noncomparative phase II study

S-1 is an oral fluoropyrimidine consisting of the 5-fluorouracil prodrug tegafur combined with two modulating substances, gimeracil and potassium oxonate. On the basis of the potential additive effect between mitomycin C (MMC) and 5-fluorouracil as a continuous infusion, we conducted a phase II study to assess the efficacy and tolerability of the combination of S-1 and MMC as second-line chemotherapy for advanced gastric cancer (AGC). Patients with measurable AGC, progressive after one prior chemotherapy for metastatic disease, received MMC (7 mg/m2) on day 1 and S-1 (40 mg/m2) twice daily as an intermittent regimen of 4 weeks of treatment followed by a 2-week rest. Treatment was repeated every 6 weeks. The primary objective was the response rate. For 43 patients registered, 42 patients were treated with MMC plus S-1. A total of 121 chemotherapy cycles were delivered (median: 2; range: 1-6). The patients' median age was 53 years (range: 31-75) and nine (21%) had an Eastern Cooperative Oncology Group performance status of 2. In an intent-to-treat analysis, nine patients (21%) achieved an objective response, which was maintained for 4.1 months. The median progression-free and overall survivals were 3.4 months (95% confidence interval: 2.3-4.5) and 8.0 months (95% confidence interval: 6.1-9.9), respectively. Although fatigue was the most frequently encountered toxicity safety profiles were generally predictable and manageable. One patient developed hemolytic anemia, which was resolved spontaneously. Grade > or = 2 hand-foot syndrome was observed in only three patients. Second-line chemotherapy with MMC and S-1 is an active and tolerable regimen for AGC patients with good performance status.

Salvage chemotherapy with irinotecan and cisplatin in patients with metastatic gastric cancer failing both 5-fluorouracil and taxanes

We conducted a phase II study to assess the efficacy and tolerability of irinotecan and cisplatin as salvage chemotherapy in patients with advanced gastric adenocarcinoma, progressing after both 5-fluorouracil (5-FU)- and taxane-containing regimen. Patients with measurable metastatic gastric cancer, progressive after previous chemotherapy that consisted either of a 5-FU-based regimen followed by second-line chemotherapy containing taxanes or a 5-FU and taxane combination were treated with irinotecan and cisplatin. Irinotecan 70 mg/m(2) was administered on day 1 and day 15; cisplatin 70 mg/m(2) was administered on day 1. Treatment was repeated every 4 weeks. For 28 patients registered, a total of 94 chemotherapy cycles were administered. The patients' median age was 51 years and 27 (96%) had an ECOG performance status of 1 or below. In an intent-to-treat analysis, seven patients (25%) achieved a partial response, which maintained for 6.3 months (95% confidence interval 6.2-6.4 months). The median progression-free and overall survival were 3.5 and 5.6 months, respectively. Major toxic effects included nausea, diarrhea and neurotoxicity. Although there was one possible treatment-related death, toxicity profiles were generally predictable and manageable. We conclude that irinotecan and cisplatin is an active combination for patients with metastatic gastric cancer in whom previous chemotherapy with 5-FU and taxanes has failed.     

Phase I dose escalation study of oxaliplatin combined with oral tegafur-uracil and leucovorin in patients with advanced gastric cancer

Our aim was to determine the dose-limiting toxicities (DLTs), maximum tolerated dose (MTD) and recommended dose of oxaliplatin combined with oral tegafur-uracil and leucovorin. Twenty-eight chemo-naive patients with advanced gastric cancer were enrolled. Oxaliplatin (55, 70, 85, 100 and 115 mg/m2) was given as a 2-h infusion on days 1 and 15. Oral tegafur-uracil (300 mg/m2 per day) and leucovorin (60 mg/day) were given 3 times a day from days 1 to 21 (28-day cycle). DLTs were defined as grade IV hematologic toxicity or grade III non-hematologic toxicity. The MTD for oxaliplatin was 100 mg/m2. The most common DLT was diarrhea. Major grade III/IV toxicities included vomiting, diarrhea, renal dysfunction, leukopenia and thrombocytopenia. There were two treatment-related deaths. Intent-to-treat response was graded as partial response in 13 patients (46.4%; 95% confidence interval 26.74-66.12%), stable disease in nine and disease progression in five. As of June 2004, 17 patients had died. The median time to treatment failure, time to progression and overall survival were 124, 308 and 434 days, respectively. The recommended dose for the phase II study is oxaliplatin 100 mg/m2 biweekly with oral tegafur-uracil (300 mg/m2 per day) and leucovorin (60 mg/day) 3 times a day for 21 days.     

Phase II study of oxaliplatin in combination with continuous infusion of 5-fluorouracil/leucovorin as first-line chemotherapy in patients with advanced gastric cancer

This study was designed to determine the efficacy and safety of biweekly oxaliplatin in combination with infusional 5-fluouracil (5-FU) and leucovorin in patients with advanced gastric cancer (AGC). Fifty-five eligible patients with measurable or assessable M/AGC (median age 62 and 90% of patients presented with metastasis) received oxaliplatin (85 mg/m2) intravenous infusion for 2 h, followed by intravenous infusion of 5-FU (3000 mg/m2) and leucovorin (100 mg/m2) for 46 h every 14 days until the patient's disease was either in progression, unacceptable toxicity, patient's withdrawal or the investigators' decision to discontinue treatment. Of the 55 enrolled patients, 48 were evaluable for response. Three patients (5.4%) showed complete remission and 20 patients (36.4%) achieved partial response. The overall response rate was 47.9%. Nineteen patients (34.5%) had stable disease and six patients (10.9%) showed progressive disease. The median time to progression was 5.6 months and the median overall survival was 10.8 months. Grade 3/4 toxicities included leucopenia (12.7%), thrombocytopenia (5.4%), diarrhoea (3.6%) and vomiting (9.1%). Peripheral neuropathy was noted in 61.8% of the patients (grade 1/2: 54.5%; grade 3: 7.3%). Our study confirmed that the combination of oxaliplatin and continuous infusion of 5-FU/leucoverin without bolus 5-FU as first-line chemotherapy is active for patients with AGC and relatively safe with lower haematological toxicity.

Docetaxel plus oxaliplatin (DOCOX) as a second-line treatment after failure of fluoropyrimidine and platinum in Chinese patients with advanced gastric cancer

The fluoropyrimidine and platinum-based combination chemotherapy is now widely used as first-line therapy for advanced gastric cancer (AGC). Unfortunately, about half of all patients do not respond to the current first-line chemotherapy and furthermore, most patients who achieve response to first-line chemotherapy eventually experience disease progression. Although there is a need for effective salvage treatment after the failure of first-line chemotherapy, data on the safety and efficacy of second-line treatment in AGC is limited. The current study evaluated an experimental combination regimen of docetaxel (60 mg/m) as an intravenous infusion of less than 1 h, followed by oxaliplatin (130 mg/m) intravenously for less than 2 h. Both drugs were administered on day 1 of a 21-day cycle, in pretreated Chinese patients with AGC. The trial enrolled 48 patients of whom 46 (95.8%) were assessable for response. The median time to progression was 4.4 months (95% confidence interval (CI): 3.4-5.4 months) and the median overall survival was 7.2 months (95% CI: 6.6-12.1 months). Partial response was confirmed in 11 of 48 cases (22.9%; 95% CI: 10.9-34.9%) and no complete responses were seen. Significant hematologic toxicity was noted with grade 3 and grade 4 neutropenia occurring in 21.7 and 4.3% of patients, respectively, as well as grade 3 thrombocytopenia occurring in 4.3% of patients. Grade 3 febrile neutropenia occurred in 6.5% of the patients. There were no treatment-related deaths during on the study. In summary, docetaxel and oxaliplatin have modest activity with predictable hematologic toxicity when given as salvage therapy for Chinese patients treated earlier for AGC. Given the short duration of response more focus should be given to newer biologic agents and triplet regimens.     

A phase II study of induction chemotherapy followed by concurrent chemoradiotherapy in elderly patients with locally advanced non-small-cell lung cancer

The optimal management of unresectable locally advanced non-small-cell lung cancer in older patients has not been defined to date. The present phase II study was planned to evaluate the activity and safety of platinum-based induction chemotherapy followed by concurrent chemoradiotherapy in elderly patients with locally advanced non-small-cell lung cancer. Patients received two cycles of paclitaxel (175 mg/m) and carboplatin (area under the curve: 5) day 1, every 3 weeks. Chemoradiotherapy (thoracic radiation therapy) was initiated on day 42 and consisted of 1.8 Gy daily, five times per week over 5 weeks (45.0 Gy target dose) followed by 10 2.0 Gy daily fractions. Concomitant chemotherapy was weekly paclitaxel 50 mg/mq followed by weekly carboplatin at an area under the curve of 2. The eligibility for patients: age 70 or older and histologically documented untreated non-small-cell lung cancer, locally advanced, unresectable, stage III A N2 bulky or III B. Thirty consecutive patients were enrolled onto the study. The median age was 73 (range 70-76). According to the intention-to-treat analysis, 1 month after the end of combined chemoradiotherapy, we observed complete and partial responses in one and 19 of the 30 patients, respectively, for an overall response rate of 66% (95% confidence interval, 45-76%). Median progression-free survival was 8.7 months (95% confidence interval, 3.4-37.8) and median survival was 15 months (95% confidence interval, 4.2-52.1). During the treatment, 12 patients (40.0%) experienced grade 3-4 neutropenia, two patients neutropenic fever, and three patients grade 3 anaemia and grade 3 thrombocytopenia, respectively. Grade 3 oesophagitis, during concomitant radiotherapy, was observed in six patients (20.0%). No treatment-related mortality was reported. The investigated sequential approach including induction chemotherapy followed by concurrent chemoradiotherapy appears safe and seems a reasonable chance for the treatment of locally advanced non-small-cell lung cancer in the elderly population.     

多西紫杉醇联合奥沙利铂、卡培他滨治疗晚期胃癌的疗效观察

目的:观察多西紫杉醇联合奥沙利铂、卡培他滨治疗晚期胃癌的临床疗效和毒副反应。方法:选择不能手术或手术后复发的晚期胃癌患者80例,随机分为试验组和对照组,各40例。试验组采用多西紫杉醇60mg·m-2,静脉滴注,第1天;奥沙利铂130mg·m-2,静脉滴注,第1天;卡培他滨800mg·m-2,口服,bid,第1～14天。对照组采用顺铂20mg·m-2,静脉滴注,第1～5天;5-氟尿嘧啶500mg·m-2,静脉滴注,第1～5天。2组均以21d为1个周期。至少2周期后评价疗效及毒副反应。结果:试验组40例患者有38例可评价疗效,有效率为55.3%,中位疾病进展时间(TTP)为6.6个月,中位总体生存时间(OS)为11.3个月。对照组40例均可评价疗效,有效率42.5%,中位TTP为5.1个月,中位OS为8.9个月。2组差异无统计学意义(P>0.05)。毒副反应主要为骨髓抑制、消化道反应、外周神经毒性,大部分患者可以耐受。结论:多西紫杉醇联合奥沙利铂、卡培他滨治疗晚期胃癌疗效肯定,毒副反应可耐受,可作为主要治疗方案。
