| Popis: | BACKGROUND: The management of locally advanced carcinomas of the esophagus and esophagogastric junction has undergone a major evolution over the past two decades with the widespread use of combined modality therapy. Although many Indian centers practice the combined modality therapy with neoadjuvant chemoradiation (nCRT), published data are sparse. OBJECTIVES: The objective of this study was to study the safety and efficacy of nCRT in patients with locally advanced resectable carcinoma of the esophagus. MATERIALS AND METHODS: Prospective single-arm study of the first fifty patients enrolled over 3 years (2014–2016). RESULTS: The median age was 51 years (M:F = 3:2), 90% of the patients had squamous cell carcinomas, and 69% had lower-third lesions. All accrued patients completed the intended dose of radiation; however, approximately 20% had a treatment delay, which was duly gap corrected. Importantly, there were no treatment-related toxic deaths. Eleven patients could not undergo surgery following nCRT (two patients defaulted, two were deemed medically unfit, and seven (14%) patients had disease progression on imaging). Thirty-nine (78%) patients were planned for definitive surgery; however, a further 7 (14%) were found to be inoperable intraoperatively. Thirty-two patients successfully completed their definitive surgical procedures with R0 resections, of which 19 patients (38%) had a pathological complete response (pCR). There was no postoperative 90-day mortality in our study cohort. Analysis of prognostic factors that predicted a response showed that patients who had adenocarcinoma and with circumferential lesions responded poorly. CONCLUSION: nCRT appears to be a safe and a reasonably well-tolerated option in carefully selected patients with resectable locally advanced esophageal cancers. Although our data are not mature to analyze the survival outcomes with a pCR rate of 38%, it suggests nCRT to be a promising option in the management of locally advanced resectable esophageal cancers. |
