不能手术的Ⅲ期非小细胞肺癌患者每周紫杉醇和卡铂并同步放疗的诱导化疗:一个Ⅱ期研究结果(英文)

Objective: several trials have suggested the superiority of concurrent chemoradiotherapy. It has been hypothesized that the addition of systemic dose sequential chemotherapy to concurrent chemoradiotherapy, as induction or as consolidation, might further improve survival rates. So we sought to evaluate the safety and efficacy of induction paclitaxel and carboplatin followed by weekly paclitaxel and carboplatin with concurrent radiotherapy in inoperable stage Ⅲ non-small cell lung cancer (NSCLC). Methods: Fifty-six patients with stage Ⅲ inoperable NSCLC received induction chemotherapy with 2 cycles of paclitaxel 200 mg/m2 and carboplatin AUC-6 every 3 weeks then patients were assigned to concurrent chemoradiotherapy with paclitaxel 45 mg/m2 and carboplatin AUC-2 weekly along with concurrent radiotherapy at dose of 60 Gy (1.8 Gy/d x 5 d/week). Results: Median age of the 56 eligible patients was 61 years, most of them were males (87.5%). Squamous cell carcinoma was the most common pathological type (55.4%) and 85.7% had a performance status of 1. The majority of patients were presented with stage ⅢB (62.5%). Neutropenia was the most common toxicity during induction therapy (12.5% expressed grade 3) whereas esophagitis was the most common non hematologic adverse reaction during concurrent chemoradiotherapy (14.3% of grade 3). The overall response rate was 71.6% with complete response in 19.6%. After median follow up of 20 months, the median survival time was 13 months (95% CI: 10.917-15.083) and 1 year overall survival rate was 53.6%. Conclusion: This regimen has demonstrated an acceptable toxicity profile and encouraging response to treatment. Evaluation of this regimen in larger number and a phase Ⅲ trial are recommended.

Twice-weekly paclitaxel and weekly carboplatin with concurrent thoracic radiation followed by carboplatin/paclitaxel consolidation for stage III non-small-cell lung cancer: a California Cancer Consortium phase II trial.

PURPOSE: Recent studies have suggested the superiority of concurrent chemoradiotherapy and the efficacy of paclitaxel/carboplatin in advanced non-small-cell lung cancer (NSCLC). In view of those results, we sought to examine the safety and efficacy of administration of radiosensitizing paclitaxel twice weekly and carboplatin weekly with concurrent thoracic radiation therapy (XRT) followed by consolidation paclitaxel and carboplatin for stage III NSCLC in a multi-institutional phase II trial. PATIENTS AND METHODS: Induction chemoradiotherapy consisted of paclitaxel 30 mg/m2 delivered intravenously (IV) for 1 hour twice weekly for 6 weeks, carboplatin at a dose based on an area under the concentration-time curve (AUC) of 1.5 mg/mL x min, given IV once weekly for 6 weeks, and concomitant XRT of 1.8 to 2.0 Gy daily for a total of 61 Gy. Patients who achieved a complete response, partial response, or stable disease received two 21-day cycles of consolidation chemotherapy consisting of paclitaxel 200 mg/m2 IV for 3 hours and carboplatin at a dose based on an AUC of 6 mg/mL x min. RESULTS: Thirty-four patients were eligible. Their median age was 62 years (range, 39 to 73 years), 59% were female, 41% were male, 94% had a performance status of 0 or 1, 38% had stage IIIA NSCLC, and 62% had stage IIIB NSCLC. Common grade III and IV toxicities during the induction chemoradiation phase included esophagitis (38%) and neutropenia (12%). The most common adverse reaction during consolidation chemotherapy was grade III neutropenia in five patients (15%). The overall response rate was 71%, which was achieved in the induction phase. The median follow-up was 20 months, the median survival was 17 months, and 2-year actuarial survival rate was 40% (95% confidence interval, 20% to 65%). CONCLUSION: This regimen is tolerable and results are promising. We recommend further evaluation of this regimen in a phase III trial.     

Induction chemotherapy with paclitaxel plus carboplatin followed by paclitaxel with concurrent radiotherapy in stage IIIB non-small-cell lung cancer (NSCLC) patients: a phase II trial

PURPOSE: We conducted a prospective phase II trial to evaluate the efficacy and toxicity of induction chemotherapy with paclitaxel plus carboplatin followed by concurrent radiotherapy with weekly paclitaxel in stage IIIB non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS: Patients with stage IIIB NSCLC received two 3-week cycles of paclitaxel 200mg/m(2) combined with carboplatin (target area under the plasma concentration curve (AUC) of 6 mg/ml) followed by weekly paclitaxel 50mg/m(2) concurrently with radiotherapy consisted of 2 Gy daily, 5 days per week (60 Gy total dose in 6 weeks). The median follow-up period was 5 years. RESULTS: Between March 1999 and January 2002, 21 patients were enrolled and analyzed. Ninety percent of patients completed the planned treatment schedule. The overall response rate was 76% (24% complete response and 52% partial response). The median overall survival time was 15 months and the 1-year, 2-year and 5-year overall survival rates were 57, 33 and 24%, respectively. The disease progression rate at 1 year was 43% and the median progression-free survival was 8 months. During the chemoradiation period, grade 3-4 oesophagitis and pneumonitis were observed in 24 and 14% of patients, respectively. CONCLUSIONS: Induction chemotherapy with carboplatin and paclitaxel followed by weekly paclitaxel with concurrent radiotherapy was found to be active and tolerable in selected stage IIIB NSCLC patients. Further studies are needed to improve the safety profile and outcome in this setting.

Phase I/II study of concurrent twice-weekly paclitaxel and weekly cisplatin with radiation therapy for stage III non-small cell lung cancer

The optimal chemoradiation regimen for stage III non-small cell lung cancer (NSCLC) has not been determined. In this phase I/II study, the use of twice-weekly paclitaxel concomitant with weekly cisplatin and thoracic radiotherapy (RT) was evaluated. Patients with stage III NSCLC (without pleural effusion or cervical lymphadenopathy) were treated with thoracic RT (60 Gy in 30 fractions over 6 weeks) with concurrent weekly cisplatin 20 mg/m(2) and escalating doses of twice-weekly paclitaxel (starting dose of paclitaxel of 20 mg/m(2) increased in increments of 5 mg/m(2)) in successive cohorts of three to six patients until two or more patients experienced dose limiting toxicities (DLTs) at a particular dose level. All patients were planned to be given a further two cycles of consolidation chemotherapy consisting of paclitaxel 175 mg/m(2) and carboplatin AUC 5 after completion of RT. Twenty-five patients were enrolled in this study from two institutions. At a dose of paclitaxel 35 mg/m(2), two of four treated patients had DLTs (1 grade 3 oesophagitis and pulmonary toxicity; 1 grade 3 oesophagitis and infection). The recommended dose was therefore determined to be 30 mg/m(2) and a total of 15 patients were enrolled in an expanded cohort at this level. The overall response rate for all patients was 64% (95% CI: 43-82%). The estimated median survival was 23.6 months with an estimated 1-year and 2-year survival of 72 and 49%, respectively. Paclitaxel can be safely given twice-weekly at a dose of 30 mg/m(2) in combination with weekly cisplatin (20 mg/m(2)) and thoracic RT (60 Gy), and this regimen has significant activity in stage III NSCLC.     

Neoadjuvant concurrent chemoradiation with weekly paclitaxel and carboplatin for patients with oesophageal cancer: a phase II study

This study was performed to assess the efficacy and safety of preoperative chemoradiation consisting of carboplatin and paclitaxel and concurrent radiotherapy for patients with resectable (T2-3N0-1M0) oesophageal cancer. Treatment consisted of paclitaxel 50 mg m(-2) and carboplatin AUC=2 on days 1, 8, 15, 22 and 29 and concurrent radiotherapy (41.4 Gy in 23 fractions, 5 days per week), followed by oesophagectomy. All 54 entered patients completed the chemoradiation without delay or dose-reduction. Grade 3-4 toxicities were: neutropaenia 15%, thrombocytopaenia 2%, and oesophagitis 7.5%. After completion of the chemoradiotherapy 63% had a major endoscopical response. Fifty-two patients (96%) underwent a resection. The postoperative mortality rate was 7.7%. All patients had an R0-resection. The pathological complete response rate was 25%, and an additional 36.5% had less than 10% vital residual tumour cells. At a median follow-up of 23.2 months, the median survival time has not yet been reached. The probability of disease-free survival after 30 months was 60%. In conclusion, weekly neoadjuvant paclitaxel and carboplatin with concurrent radiotherapy is a very tolerable regimen and can be given on an outpatient basis. It achieves considerable down staging and a subsequent 100% radical resection rate in this series. A phase III trial with this regimen is now ongoing.     

A phase II study of weekly paclitaxel and carboplatin in previously untreated patients with advanced non-small-cell lung cancer

Purpose: Both paclitaxel (P) and carboplatin (C) have a significant activity in non-small cell lung cancer (NSCLC). Weekly administration of P is active, is dose intense, and has a favorable toxicity profile. To evaluate the efficacy and toxicity of weekly P and C in advanced-stage NSCLC, we initiated this phase II study in patients with advanced NSCLC (III B with pleural effusion and stage IV). Patients and Methods: Eligible patients were treated with paclitaxel 100 mg/m² intravenously (iv) over 1 h followed by carboplatin AUC 2 iv over 30 min. This treatment was administered weekly for 3 of every 4 wk until disease progression or intolerable toxicities. Results: Of the 30 patients enrolled in the study, one patient did not meet the eligibility criteria. Of the remaining 29 patients, 6 did not complete at least two cycles of treatment and hence were not assessable for response. The overall response rate was 43.5% (10/23) (all partial responses). An additional 43.5% had stable disease. The median time to progression was 162 d and the median duration of response was 169 d. Overall survival at 1 yr on intent-to-treat analyses was 44% and median survival was 10.8 mo. We observed the following grade 3/4 toxicities: hypersensitivity to paclitaxel (13%), hypersensitivity to carboplatin (3%), neutropenia (31%), thrombocytopenia (7%); 31% experienced grade 1 neuropathy and 17% experienced grade 2 neuropathy. Conclusions: We conclude that weekly paclitaxel and carboplatin is active and very well tolerated in patients with advanced NSCLC.
