A comparison of carboplatin and paclitaxel with cisplatinum and 5-fluorouracil in definitive chemoradiation in esophageal cancer patients.

ABSTRACT:

Background

In esophageal cancer (EC) patients who are not eligible for surgery, definitive chemoradiation (dCRT) with curative intent using cisplatinum with 5-fluorouracil (5-FU) is the standard chemotherapy regimen. Nowadays carboplatin/paclitaxel is also often used. In this study, we compared survival and toxicity rates between both regimens.

Patients and methods

This multicenter study included 102 patients treated in five centers in the Northeast Netherlands from 1996 till 2008. Forty-seven patients received cisplatinum/5-FU (75 mg/m(2) and 1 g/m(2)) and 55 patients carboplatin/paclitaxel (AUC2 and 50 mg/m(2)).

Results

Overall survival (OS) was not different between the cisplatinum/5-FU and carboplatin/paclitaxel group {[P = 0.879, hazard ratio (HR) 0.97 [confidence interval (CI) 0.62-1.51]}, with a median survival of 16.1 (CI 11.8-20.5) and 13.8 months (CI 10.8-16.9). Median disease-free survival (DFS) was comparable [P = 0.760, HR 0.93 (CI 0.60-1.45)] between the cisplatinum/5-FU group [11.1 months (CI 6.9-15.3)] and the carboplatin/paclitaxel group [9.7 months (CI 5.1-14.4)]. Groups were comparable except clinical T stage was higher in the carboplatin/paclitaxel group (P = 0.008). High clinical T stage (cT4) was not related to OS and DFS in a univariate analysis (P = 0.250 and P = 0.201). A higher percentage of patients completed the carboplatin/paclitaxel regimen (82% versus 57%, P = 0.010). Hematological and nonhematological toxicity (?grade 3) in the carboplatin/paclitaxel group (4% and 18%) was significantly lower than in the cisplatinum/5-FU (19% and 38%, P = 0.001).

Conclusions

In this study, we showed comparable outcome, in terms of DFS and OS for carboplatin/paclitaxel compared with cisplatinum/5-FU as dCRT treatment in EC patients. Toxicity rates were lower in the carboplatin/paclitaxel group together with higher treatment compliance. Carboplatin/paclitaxel as an alternative treatment of cisplatinum/5-FU is a good candidate regimen for further evaluation.

Project description:IntroductionThe impact of selective surgical resection for patients with esophageal cancer treated with definitive chemoradiation has not been clearly evaluated long-term.MethodsNRG (National Surgical Adjuvant Breast and Bowel Project, Radiation Therapy Oncology Group, Gynecologic Oncology Group) Oncology Radiation Therapy Oncology Group 0246 was a multi-institutional, single-arm, open-label, nonrandomized phase II study that enrolled 43 patients from September 2003 to March 2008 with clinical stage T1-4N0-1M0 squamous cell or adenocarcinoma of the esophagus or gastroesophageal junction from 19 sites. Patients received induction chemotherapy with fluorouracil (650 mg/m2/d), cisplatin (15 mg/m2/d), and paclitaxel (200 mg/m2/d) for two cycles followed by concurrent chemoradiation consisting of 50.4 Gy of radiation (1.8 Gy per fraction) and daily fluorouracil (300 mg/m2/d) with cisplatin (15 mg/m2/d) over the first 5 days. After definitive chemoradiation, patients were evaluated for residual disease. Selective esophagectomy was considered only for patients with residual disease after chemoradiation (clinical incomplete response) or recurrent disease on surveillance.ResultsThis report looks at the long-term outcome of this selective surgical strategy. With a median follow-up of 8.1 years (minimum to maximum for 12 alive patients 7.2-9.8 years), the estimated 5- and 7-year survival rates are 36.6% (95% confidence interval [CI]: 22.3-51.0) and 31.7% (95% CI: 18.3-46.0). Clinical complete response was achieved in 15 patients (37%), with 5- and 7-yearr survival rates of 53.3% (95% CI: 26.3-74.4) and 46.7% (95% CI: 21.2-68.7). Esophageal resection was not required in 20 of 41 patients (49%) on this trial.ConclusionsThe long-term results of NRG Oncology Radiation Therapy Oncology Group 0246 demonstrate promising efficacy of a selective surgical resection strategy and suggest the need for larger randomized studies to further evaluate this organ-preserving approach.
