- W2006329075 abstract "Objective The objective of this prospective, nonrandomized study was to evaluate the immediate and long-term results of first-line chemotherapy and possible surgery in locally advanced, presumably T4 squamous cell esophageal cancer. Summary Background Data Locally advanced esophageal cancer is rarely operable and has a dismal prognosis. For this reason, neoadjuvant cytoreductive treatments are more and more frequently used with the aim of downstaging the tumor, increasing the resection rate, and possibly improving survival. Methods From January 1983 to December 1991, 163 consecutive patients with a presumedly T4 squamous cell carcinoma of the thoracic esophagus (group A) received on average 2.5 cycles (range, 1-6) of first-line chemotherapy with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 per day, in continuous infusion from day 1 through day 5). Chemotherapy was followed by surgery when adequate downstaging of the tumor was obtained. Results Chemotherapy toxicity was WHO grade 0 to 2 in 80% of cases, but 3 toxic deaths (1.9%) occurred. Restaging suggested a downstaging of the tumor in 101 of 163 patients (62%), but only 85 patients (52%) underwent resection surgery; it was complete or R0 in 52 (32%) and incomplete or R1-2 in 33. Overall postoperative mortality was 11.7% (10 of 85), morbidity 41% (35 of 85). Complete pathologic response was documented in 6 patients, and significant downstaging to pStage I, IIA, or IIB occurred in 25 more patients. The overall 5-year survival was 11% (median, 11 months). After resection surgery, the 5-year survival was 20% (median, 16 months); none of the nonresponders survived 4 years after palliative treatments without resection (median survival, 5 months). The 5-year survival rate of the 52 patients undergoing an R0 resection was 29% (median, 23 months). Stratifying patients according to the R, pT, pN, and pStage classifications, the survival curves were comparable to the corresponding data obtained in the 587 group B patients with potentially resectable esophageal cancer who underwent surgery alone during the same period. Furthermore, the results were improved in comparison with 136 previous or subsequent patients with a locally advanced tumor who did not undergo neoadjuvant treatments (group C). In these patients, the R0 resection rate was 7%, and the overall 5-year survival was 3% (median, 5 months). Conclusion Although nonrandomized, these results suggest that in locally advanced esophageal carcinoma, first-line chemotherapy increases the resection rate and improves the overall long-term survival. In responding patients who undergo R0 resection surgery, the prognosis depends on the final pathologic stage and not on the initial pretreatment stage." @default.
