Esophageal cancer (EC) ranks as the 7th most prevalent form of cancer and the 6th leading cause of cancer-related mortality globally. Neoadjuvant therapy, encompassing neoadjuvant chemotherapy or chemoradiotherapy, has shown promise in reducing the staging of EC and mitigating the risk of early systemic spread. This study seeks to assess the safety and viability of implementing neoadjuvant chemoradiotherapy (nCRT) in conjunction with radical esophagectomy surgery for Vietnamese patients diagnosed with locally advanced EC. Safety was evaluated based on the incidence of grade ≥3 treatment-related adverse events, while feasibility was assessed through indicators such as pathological complete response, major pathological response, and R0 resection rates. The study analyzed data from 30 patients, following specific inclusion criteria. Baseline characteristics analysis revealed a participant cohort entirely composed of males, wherein 83.3% were identified as smokers, with tumors predominantly located in the middle (46.7%) and lower (53.3%) regions of the thoracic esophagus. The predominance of clinical stages II and III was observed. The nCRT protocol resulted in a substantial reduction in dysphagia score, with a statistically significant P < .001. The median duration from the conclusion of radiation treatment to surgery was 62 days, with a median operative time of 302 minutes and a median estimated blood loss of 189 mL. Surgical complications primarily included anastomotic leakage and pneumonia, occurring in 23.3% and 16.7% of cases, respectively. R0 resection was achieved in 29 (96.7%) patients, with 43.4% attaining pathological complete response and 56.7% demonstrating tumor complete response. The study's outcomes emphasize the safety and feasibility of employing esophagectomy subsequent to nCRT in Vietnamese patients, as evidenced by the absence of mortality, low complication rates, and favorable surgical results. It also suggests the potential advantages of utilizing a lower daily Gy dose for enhanced safety and considering squamous cell carcinoma as a specific criterion for nCRT.
食管癌(EC)是全球第七大常见癌症类型,也是癌症相关死亡的第六大主要原因。新辅助治疗,包括新辅助化疗或放化疗,已显示出在降低食管癌分期和减轻早期全身扩散风险方面的前景。本研究旨在评估对诊断为局部晚期食管癌的越南患者实施新辅助放化疗(nCRT)联合根治性食管切除术的安全性和可行性。基于≥3级治疗相关不良事件的发生率评估安全性,而通过病理完全缓解、主要病理缓解和R0切除率等指标评估可行性。该研究按照特定纳入标准分析了30例患者的数据。基线特征分析显示参与者队列全为男性,其中83.3%被确定为吸烟者,肿瘤主要位于胸段食管的中段(46.7%)和下段(53.3%)。观察到临床分期以II期和III期为主。nCRT方案使吞咽困难评分大幅降低,P<0.001,具有统计学意义。从放疗结束到手术的中位时间为62天,中位手术时间为302分钟,中位估计失血量为189毫升。手术并发症主要包括吻合口漏和肺炎,分别发生在23.3%和16.7%的病例中。29例(96.7%)患者实现了R0切除,43.4%达到病理完全缓解,56.7%显示肿瘤完全缓解。该研究结果强调了在越南患者中nCRT后采用食管切除术的安全性和可行性,无死亡病例、低并发症发生率和良好的手术结果证明了这一点。研究还表明,使用较低的每日Gy剂量以提高安全性以及将鳞状细胞癌作为nCRT的特定标准可能具有优势。
