Treating esophageal cancer with a combination of chemotherapy, radiation, and excision

Treatment of esophageal cancer has been primarily palliative. Recent studies have shown that preoperative combination chemo- and radiation therapy increases the effectiveness of surgical excision.

Beginning in 1990, 29 patients in the Spokane area were treated with preoperative chemo- and radiation therapy. They were 23 men and 6 women whose mean age was 66 years. Twenty-five had adenocarcinoma, of whom 3 had Barrett's esophagitis. Four had squamous cell carcinoma. The chemotherapy included fluorouracil, cisplatin, and vinblastine. Radiation was given concomitantly, BID for 21 days. Surgical excision was performed about 3 weeks after the last radiation session, pending recovery from cytopenia.

There was 1 operative death, for an operative mortality of 3.4%. Twenty-three patients (79%) were found to have no residual cancer at the time of resection. Of this group, 8 died of metastatic cancer at a mean of 15 months postoperatively (range 1 to 28), and 15 were alive at a mean of 28 months (range 12 to 46). Six patients (21%) had residual cancer in the resected specimen, either at the primary site or--more often--in adjacent lymph nodes. Five have died at 6, 8, 9, 24, and 28 months postoperatively; 1 remains alive at 14 months. The mean survival among these 6 patients is 15 months.

Combined chemo- and radiation therapy prior to esophagectomy appeared to improve outcome in this small series of patients with esophageal cancer. Local control was excellent, but distant metastasis continues to be a significant problem.
