title: Combined cis-platinum plus radiation antitumor activity in locoregionally advanced squamous cell esophageal cancer.
abstract: The synergistic activity we have observed in vitro in V-79 hamster lung cells after treatment with cis-platinum combined with irradiation, stimulated a pilot study of 31 patients with inoperable locoregionally advanced squamous cell esophageal cancer. The 27 evaluable cases (22 men and 5 women--mean age 59 years) had undergone no prior radiation or cytostatic drug therapy. Histological evidence of the tumor (26 squamous cell, 1 adenocarcinoma) was obtained by endoscopy in all patients before treatment began. The patients were irradiated in two opposite thoracic fields with a total dosage of 3,000-4,000 cGy (200 cGy daily, 1,000 weekly) concurrently with 2 cycles of cis-platinum in the dosage of 30 mg/m2 iv. daily X 4 (120 mg/m2 per cycle). The results showed that cis-platinum combined with radiation showed an evident antitumor activity which included 4 complete clinical remissions and 11 partial remissions with a response rate of 56% (15/27). In two complete responders even a pathologic remission was evident (biopsy specimen) and they are now 16+ and 18+ months free of the disease. The median remission duration has been 8+ months (14+ months in complete responders) and the median survival period for the entire group is 10+ months (for responders 15+ months, p less than 0.05). Toxicity was moderate and reversible, and mainly accounted for radiation mucositis, retrosternal pain and vomiting. A mild bone marrow suppression was observed. In 2 cases esophagotracheal fistulae occurred. The results of this study show that the combination of cis-platinum and radiation might constitute successful palliative or neoadjuvant treatment for squamous cell esophageal cancer.
