Abstract

PURPOSE:

To evaluate the safety and efficacy of a modified administration schedule of docetaxel, cisplatin, and fluorouracil (mDCF) with bevacizumab in patients with advanced gastroesophageal malignancies.

PATIENTS AND METHODS:

Previously untreated patients with metastatic gastroesophageal adenocarcinoma received bevacizumab 10 mg/kg, docetaxel 40 mg/m², fluorouracil 400 mg/m², leucovorin 400 mg/m² on day 1, fluorouracil 1,000 mg/m²/d × 2 days intravenous continuous infusion beginning on day 1, and cisplatin 40 mg/m² on day 3. The primary objective was to improve 6-month progression-free survival (PFS) from 43% (historical DCF control) to 63% with the addition of bevacizumab. The target accrual was 44 patients to have 10% type I and II error rates.

RESULTS:

In total, 44 eligible patients with cancer were enrolled from October 2006 to October 2008: 22 gastric, 20 gastroesophageal junction (GEJ), and two esophagus. In 39 patients with measurable disease, the confirmed response rate was 67% (95% CI, 50% to 81%). Six-month PFS was 79% (95% CI, 63% to 88%), and median PFS was 12 months (95% CI, 8.8 to 18.2 months). With 26-month follow-up, median overall survival (OS) was 16.8 months (95% CI, 12.1 to 26.1 months), and 2-year survival was 37%. Treatment-related grade 3 to 4 toxicity was as follows: neutropenia without fever (50%), fatigue (25%), venous thromboembolism (39%), and nausea, vomiting, mucositis, neuropathy, and febrile neutropenia less than 10% each. In subset analysis, diffuse gastric cancer had significantly worse PFS and OS, and the response rate in proximal/GEJ tumors was 85% (95% CI, 62% to 97%).

CONCLUSION:

mDCF with bevacizumab appears tolerable and has notable patient outcomes in patients with advanced gastroesophageal adenocarcinoma. Six-month PFS was 79%, surpassing our predefined efficacy end point, and median and 2-year OS were 16.8 months and 37%, respectively.
