Combined paclitaxel, cisplatin, and etoposide for patients with previously untreated esophageal and gastroesophageal carcinomas

BACKGROUND Paclitaxel (T), etoposide (E), and cisplatin (P) are each active in gastric carcinoma, either as single agents or as part of a multidrug regimen. To the authors' knowledge, the combination of these three agents in the treatment of patients with esophageal or gastroesophageal carcinoma has not been previously studied. METHODS Previously untreated patients with locally advanced carcinoma of the stomach, esophagus, or gastroesophageal (GE) junction received at least 2 cycles of TPE administered twice weekly for 3 weeks, with the cycle repeated every 28 days. Drug doses, administered over 3 hours on either Monday and Thursday or Tuesday and Friday, consisted of T 50 mg/m2/dose, P 15 mg/m2/dose, and E 40 mg/m2/dose. For patients with local disease only, subsequent therapy consisted of radiation with or without surgical resection. RESULTS Twenty-five patients with gastric (10) or gastroesophageal or GE junction (15) carcinoma were treated. Eighteen had locally advanced disease and 7 had liver metastases at presentation. Hematologic toxicity, namely, Grade 3 anemia and neutropenia, was experienced by all patients. The median number of treatment cycles was 4 (range, 2–6). Three patients were not evaluable for response. All 22 evaluable patients responded; 3 were complete responders and 19 were partial responders. Eleven patients received radiation therapy with (6) or without (5) concomitant 5-fluorouracil, and 8 patients subsequently underwent surgical resection. Three of 8 patients had no tumor at surgery, 4 had minimal microscopic tumor at the primary site, and 3 had microscopic lymph node involvement. Twenty-three patients are alive, of whom 14 are without evidence of disease. Two patients with metastatic disease at presentation died at 9 and 29 months, respectively. The median survival was 12.5 months (range, 6 to 30+ months). CONCLUSIONS Multifractionated TPE chemotherapy is a highly active regimen in gastric and gastroesophageal carcinoma. It could be evaluated in Phase III trials against other active regimens for the treatment of patients with this disease. The introduction of 5-fluorouracil could also be an interesting direction to explore because of its primary role in the treatment of patients with gastric and esophageal carcinoma.
