Vinorelbine versus paclitaxel for patients with advanced non-small cell lung cancer (NSCLC) and a performance status of 2.

AIM: The purpose of this study was to compare two single agents paclitaxel (intravenous) versus vinorelbine (oral) in non-small cell lung cancer (NSCLC) patients with performance status (PS):2. PATIENTS AND METHODS: The patients were randomized to receive either oral vinorelbine 60 mg/m(2) on days 1, 8, 15 every 4 weeks for 4 cycles (group A) or paclitaxel 90 mg/m(2) intravenously for 1 h on days 1, 8, 15 every 4 weeks for a total of 4 cycles (group B). RESULTS: Among the 74 eligible patients (36 in arm A and 38 in arm B) in arm A, two (6%) had a partial response (95% CI, 0.7-18.7) and 5 (14%) had stable disease (95% CI, 4.7-29.5). In arm B, five (13%) had a partial response (95% CI, 4.4-28.1) and 7 (18%) had stable disease (95% CI, 7.7-34.3). No significant difference was found in terms of clinical benefit between the two groups after two cycles of treatment except for appetite in favour of paclitaxel (p=0.01). Median survival was 3.1 months (95% CI, 2.2-4.0) for arm A and 5.1 months (95% CI, 2.7-7.6) for arm B (p=0.95). Toxicity was mild and only alopecia was more profound in the patients of arm B (p=0.008). CONCLUSION: No significant difference was found in clinical benefit between PS:2 NSCLC patients treated with either vinorelbine or paclitaxel.

Adjuvant chemotherapy using CPT-11, leucovorin plus bolus 5-fluorouracil and radiotherapy in patients with rectal cancer. A feasibility study.

BACKGROUND: The addition of CPT-11 to 5FU/leucovorin resulted in survival benefit in patients with advanced colorectal cancer suggesting that this combination could be used successfully in the adjuvant setting. We studied the toxicity profile of postoperatively administered CPT-11 plus leucovorin (LV)-modulated 5FU and radiotherapy in patients with rectal cancer. PATIENTS AND METHODS: Thirty-seven patients with Dukes' B2 and C rectal adenocarcinoma were treated with CPT-11, 80 mg/m2 ii.v. over 90 minutes followed by LV 200 mg/m2 over 2 hours and 5FU 450 mg/m2 i.v.-bolus weekly for 4 weeks followed by a 2-week rest period. One cycle included 4 infusions. The first cycle of chemotherapy was followed by pelvic radiation to a total dose of 45 Gy to the whole pelvis and a boost of 5 Gy to the tumor bed. 5FU was administered daily as a rapid infusion during the first 3 as well as the last 3 days of radiotherapy. CPT-11 plus LV-modulated 5FU was continued for a total of 6 cycles or consent withdrawal. RESULTS: The main toxicity was reversible diarrhea (grade 3 and 4) in 9 (26%) patients during chemotherapy and in 3 (9%) patients during chemoradiotherapy. Furthermore, grade 3 leucopenia in 2 (6%) and 1 (3%) patient was observed during chemotherapy and chemoradiotherapy, respectively. CONCLUSION: This study provides evidence that adjuvant therapy using CPT-11 plus LV modulated 5FU and radiotherapy can be used in patients with rectal cancer.
