Preoperative mitomycin, ifosfamide, and cisplatin followed by esophagectomy in squamous cell carcinoma of the esophagus: pathologic complete response induced by chemotherapy leads to long-term survival.

PURPOSE: Squamous cell carcinoma of the esophagus remains an aggressive disease with a poor prognosis, even after curative-intent surgery. This article analyzes the impact of preoperative chemotherapy with mitomycin, ifosfamide, and cisplatin (MIC) on a cohort of 68 patients. PATIENTS AND METHODS: From 1988 to 1994, 68 patients with potentially operable squamous cell carcinoma of the esophagus were entered onto two phase II trials of neoadjuvant chemotherapy with mitomycin 6 mg/m2, ifosfamide 3 g/m2, and cisplatin 50 mg/m2 and received between two and four cycles of treatment at 3-weekly intervals. Two patients were removed from the analysis when they were found to have malignancy other than squamous cell carcinoma of the esophagus. RESULTS: Forty (61%) of 66 patients had a radiologic response to chemotherapy (18 complete responses and 22 partial responses), and 52 (79%) of 66 patients went on to have the primary tumor resected. There were nine pathologic complete responders, seven of whom remain fit and well after at least 60 months of follow-up. The overall median survival was 12.4 months (95% confidence interval, 9.6 to 18.8 months). The complete response and node-negative patients survived significantly longer than those in other categories (log-rank chi2 = 18.8; P <.001): on average 13 months longer than the node-positive or nonresected category (22.0 v 9.4 months). The toxicity of the regimen was low. CONCLUSION: MIC is an easily administered, well-tolerated, and efficacious regimen as neoadjuvant therapy for patients with squamous cell carcinoma of the esophagus. These results warrant further investigation.

Combined results from three phase II trials of neoadjuvant chemotherapy in operable adenocarcinoma of the oesophagus.

Adenocarcinoma of the oesophagus is a systemic disease at presentation in the majority of patients. This article analyses the impact of preoperative chemotherapy on a cohort of 68 patients. From 1990 to 1996, 68 patients with potentially operable adenocarcinoma of the oesophagus were entered into three sequential Phase II trials of neoadjuvant chemotherapy with cisplatin/mitomycin C/ifosfamide, cisplatin/5-fluorouracil (5-FU) and mitomycin C/cisplatin/5-FU. Twenty-four (35%) patients had a radiological (4 complete; 20 partial) response to chemotherapy, and 52 (76%) went on to have the primary tumour resected. There was only one pathological complete responder. The overall median survival was 13 months (95% confidence interval (CI) 9-16). Survival for the 28 N(0) patients was 34 months (95% CI 14-60). The pattern of failure for resected patients was predominantly systemic (16/17). These results indicate that neoadjuvant chemotherapy followed by surgery for adenocarcinoma of the oesophagus achieves excellent local control. The dominance, however, of distant recurrence after surgery underlines the fact that, in the majority of patients, the only hope of improving results in the future is to develop better systemic therapies.

Palliative chemotherapy: no longer a contradiction in terms.

Palliative chemotherapy is defined as treatment in circumstances where the impact of intervention is insufficient to result in major survival advantage, but does affect improvement in terms of tumor-related symptoms, and where the palliation/toxicity trade-off from treatment clearly favors symptom relief. The role of chemotherapy in circumstances where little or no survival benefit is anticipated remains controversial. This is despite the mounting body of evidence in favor of its use for symptom palliation. The notion persists that outcomes other than significant survival benefit are not valid, because of firmly held perceptions of toxicity. Studies of chemotherapeutic palliation using valid measures of quality of life, show that patients may be willing to accept some side effects of treatment, as long as they gain relief from tumor-related symptoms. The aims of this review are to present the case for palliative chemotherapy, to highlight the areas of progress which have made this feasible, and to provide guidance with regard to its appropriate use.
