Neoadjuvant chemotherapy and radiotherapy in locally advanced esophagus carcinoma: long-term results

A prospective study with neoadjuvant chemotherapy and radiotherapy in patients with locally advanced esophagus carcinoma for evaluating: toxicity, response rate, pattern of recurrence, and survival after a long follow-up.

Between 1983-1988, 40 patients with locally advanced squamous cell carcinoma of the thoracic esophagus were entered into a prospective trial of neoadjuvant chemotherapy and radiotherapy. Eight patients (20%) were Stage II and 32 patients (80%) were Stage III, according to American Joint Committee staging criteria. Neoadjuvant chemotherapy consisted of two cycles with cisplatin (120 mg/m2 day 1), vindesine (3 mg/m2 days 1, 8, 15, and 22) and bleomycin (10 mg/m2 days 3 to 6). Second cycle was initiated on day 29. Radiation therapy was administered 2-4 weeks after completion of chemotherapy, with a total dose on tumor of 60 Gy.

Two patients died from treatment-related toxicity. Complete response was observed in 20 patients (53%) and symptomatic improvement in 31 patients (82%). The median survival was 11 months, with an actuarial survival at 1 year of 45%, 3 year 20%, and 5 years 15%. Significantly (p < 0.05) longer survival was observed in patients with Stage II (median survival 18 months) vs. Stage III (median survival 10 months). The pattern of failure was predominantly local/regional (62%).

This treatment scheme is an effective and tolerable regimen but long-term survival was poor.
