A 63-year-old man presented to our hospital with persistent dysphagia. Radiologic and endoscopic examination disclosed a 2.0-cm exophytic tumor in the middle third of the esophagus. An endscopically obtained biopsy specimen was found to represent undifferentiated small cell carcinoma. Computed tomography of the chest, abdomen, and cervical region was performed, as were gallium and bone scintigraphy. Metastasis to an adjacent lymph node was detected, without metastasis to distant organs. After neoadjuvant chemotherapy with carboplatin (CBDCA) (400 mg/m2) and etoposide (VP-16) (100 mg/m2), endoscopy and barium-swallow esophagography showed regression. Thoracic esophagectomy then was performed with mediastinal, abdominal and cervical lymph node dissection. The resected tumor was polypoid, measuring 0.5 x 0.5 cm. The lesion consisted mainly of small anaplastic cells, but included a small focus of squamous cell carcinoma. The patient has survived for more than 7 months with no further treatment and no evidence of recurrent disease.

Based on both clinical and laboratory data that suggested that tamoxifen (TAM) enhanced the effectiveness of cisplatin (DDP)-based chemotherapy regimens, the Cancer and Leukemia Group B (CALGB) designed and initiated a prospective, randomized phase III trial to test the efficacy of the addition of high-dose TAM to a standard chemoradiation regimen of DDP and etoposide (VP-16) in patients with limited-stage small cell lung cancer (LS-SCLC). Between August 6, 1993, and January 15, 1999, 319 patients with LSSCLC were accrued to CALGB 9235. Patients were randomized to receive chemotherapy with or without high-dose TAM. Treatment on the non-TAM containing arm (arm 1) included DDP (80 mg/m2 intravenously day 1 only) and VP-16 (80 mg/m2 intravenously days 1-3) given every 3 weeks for a total of 5 cycles. Patients treated on arm 2 received the identical chemotherapy regimen as described here with the addition of high-dose TAM (80 mg orally twice per day), which was given for 5 days each cycle starting 1 day before the DDP. Thoracic radiation (XRT) given at 200 cGy 5 days per week to a total dose of 50 Gy began on day 1 of cycle 4 of chemotherapy and overlapped with cycle 5. Prophylactic cranial irradiation was offered to all patients who achieved a complete response or near-complete response. A total of 307 patients are evaluable for response. After the completion of the chemoradiation portion of the treatment, the overall response rate (ORR) was 88% for 154 patients treated without tamoxifen and 84% for 153 patients treated with tamoxifen with complete response (CR) rates of 49% and 50%, respectively. The median failure-free survivals of 12.3 months and 10.5 months and the overall survivals of 20.6 months and 18.4 months, respectively, were not statistically significant between the 2 arms. Toxicity was similar with and without tamoxifen. This phase III trial failed to demonstrate a positive effect on either the response or survival for the addition of TAM to standard etoposide-cisplatin-radiation management for patients with LS-SCLC. However, these data continue to support a positive effect of chemoradiation in the treatment of patients with LS-SCLC.
