Preoperative camrelizumab combined with chemotherapy for borderline resectable ESCC: A single-arm, prospective, phase 2 study.
Background: We investigated the safety and efficacy of preoperative camrelizumab combined with chemotherapy for treating thoracic borderline resectable esophageal squamous cell carcinoma (Br-ESCC) (ChiCTR2200056728).
Methods: Patients with thoracic Br-ESCC received intravenous camrelizumab plus chemotherapy and underwent esophagectomy. The primary endpoint was the pathologic complete response (pCR) rate. We introduced computed tomography and endoscopic examination into the diagnostic criteria to increase its reproducibility. Additionally, we defined a new resection status, Rbr+/-, for Br-ESCC.
Findings: Thirty-one patients with Br-ESCC were ultimately enrolled in this study. Overall, 71.0% (22/31) of the patients underwent esophagectomy. R0 resection was achieved in 81.8% of patients (18/22). pCR and major pathological response were observed in 40.9% (9/22) and 63.6% (14/22) of the resected patients, respectively. Eighteen R0 resection patients were redefined according to our Rbr definition; 61.1% (11/18) were classified as Rbr+ resection, and 38.9% (7/18) were classified as Rbr- resection. With a median postoperative follow-up of 17.9 months, 4 patients out of 11 who underwent Rbr+ resection experienced local recurrence (2 of whom achieved pCR). However, no patients (0/7) who underwent Rbr- resection experienced local recurrence.
Conclusions: Esophagectomy after neoadjuvant immunochemotherapy is a promising radical treatment for Br-ESCC. R0 resection was achieved in 81.8% of patients, and a pCR was observed in 40.9% of resected patients. Even after complete excision, Rbr+ resection leads to a higher rate of local recurrence in patients with Br-ESCC.
Funding: This study was supported by the Key Scientific Research Projects of the Institutions of Higher Learning in Henan Province (no. 21A320032).
