Real-World Experience of Patient’s Compliance and Clinical Outcomes for Trimodality Treatment for Esophageal Cancer: a Study from a Cancer Center in North-East India
Indian Journal of Surgical Oncology(2024)
Abstract
Preoperative chemoradiotherapy is a standard treatment for patients with locally advanced, resectable esophageal cancer. The treatment completion rates impact the survival outcomes (Eyck et al J Clin Oncol 39(18):1995–2004, 2021 ). Thus, we aimed to estimate the effect of neoadjuvant chemoradiotherapy (NACRT) in terms of treatment completion rates and survival in this subset of patients and bring out the clinical outcomes in that context. This was a retrospective study done at a tertiary cancer center in North-East India. The study period was from 1 January 2018 to 31 December 2021. We included patients diagnosed with locally advanced and resectable esophageal cancer (cT 2-3 N any M0) involving the middle and/or lower thoracic esophagus and who were planned for trimodality treatment in the Joint Tumor Board. Out of the 82 patients who were planned for trimodality treatment, all were squamous cell carcinomas. We found that 54.9% of patients completed the entire trimodality treatment. The median age was 56 years (range 34 to 73 years). The male to female ratio was 59:23. Adverse events, of any grade, were seen in 76% of patients who received NACRT. Fatigue (66%) was the most common toxicity. The common hematologic toxicities were neutropenia and anemia (7.3% each). A total of 45 patients (54.9%) were able to complete all the three modalities of treatment. Transthoracic esophagectomy was the preferred approach (84.4%). The site of anastomosis was in the neck of all the patients. Anastomotic leak was seen in 17.7% of patients. Postoperative pulmonary and cardiac complications occurred in 31.1% and 8.9% of patients respectively. The 30-day mortality was 6.7% (three deaths). A pathological complete response was seen in 35.6% among patients who underwent an esophagectomy. R0 resection was achieved in 93.3% of patients. The median overall survival and disease-free survival were 19 months and 17 months respectively. The completion rate of trimodality treatment in the real-world scenario was found to be low in our study, the reasons for which need to be identified and effectively resolved. Oncological outcomes were similar to the published literature.
