BACKGROUND: Proximal esophageal cancer has been a disease associated with relatively poor treatment success, partly due to advanced disease at presentation and the morbidity of the surgery required. Therefore, most patients receive palliative radiation therapy, and disease control is poor. METHODS: Between July 1990 and December 1992, nine consecutive patients with proximal esophageal squamous cell carcinoma were treated with aggressive concurrent chemoradiotherapy followed by surgical resection. Treatment consisted of cisplatin (20 mg/m2/day) and 5-fluorouracil (1000 mg/m2/day), both given as continuous intravenous infusions over 4 days concurrent with accelerated fractionation external beam radiation therapy (150 cGy twice a day to a dose of 2400 cGy). Three weeks after beginning treatment, a second course of chemotherapy and accelerated fractionation radiation therapy was administered to a total preoperative radiation therapy dose of 4500 cGy. After restaging of their disease, patients next underwent surgical resection. A single postoperative course of chemotherapy and 2400 cGy of concurrent accelerated fractionation radiation therapy was administered to those patients with residual tumor in the resection specimen. Two of these nine patients also were given 4-day etoposide infusions (75 mg/m2/day) as part of their chemotherapy and received lower induction radiation therapy doses. RESULTS: Although significant toxicity was experienced, there were no deaths attributable to the chemoradiotherapy and only one perioperative death. All nine patients underwent surgery; five required pharyngolaryngoesophagectomy. No residual tumor was found in the resection specimen in three of the nine patients. Continuous locoregional tumor control was achieved in all patients. Only two developed distant metastases. CONCLUSIONS: These results, using aggressive multimodality treatment, suggest that excellent locoregional control and long term, disease free survival can be achieved in selected patients with proximal esophageal cancer.
