ABSTRACT
OBJECTIVES:
The goal of this study was to investigate the patterns and risk factors for recurrence in patients with oesophageal squamous cell carcinoma with a pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT).METHODS:
Between January 2008 and December 2018, a total of 96 patients with pCR were enrolled in this study. Lymph nodes with a pCR [LN-ypCR response (+)] were defined as those lymph nodes without residual tumour but with the presence of treatment response to nCRT. Prognostic factors for recurrence-free survival (RFS) were analysed with Cox proportional hazards models and Fine-Gray competing risk models. Lymph node (LN) stations were counted according to the Japan Esophageal Society classification.RESULTS:
The median follow-up time was 51.5 months. Recurrence occurred in 15 cases (15.6%) with a 9.9-month median time to recurrence and a 15.6-month median survival after recurrence. The majority of recurrent diseases developed within the first 2 years postoperatively. Distant recurrences were detected in 14 cases (14.6%), in which the most common recurrence sites were no.104 LN and the lung, followed by no.16 LN. The mean RFS in the whole cohort was 116.6 months. The LN-ypCR response (+) was identified as the independent prognostic factor for worse RFS in both the multivariate Cox model and the Fine-Gray competing risk model (P = 0.001 and P = 0.002, respectively).CONCLUSIONS:
Relapse is not rare in oesophageal squamous cell carcinoma cases with pCR after nCRT. Distant recurrences, the predominant pattern of relapse, occur primarily within the first 2 years after oesophagectomy. Patients with pCR with an LN-ypCR response (+) have a higher risk for postoperative recurrence.Palavras-chave
