Benefits of camrelizumab plus carboplatin and albumin paclitaxel as induction therapy for locally advanced borderline resectable or unresectable esophageal squamous cell carcinoma.

ABSTRACT

BACKGROUND: To evaluate the safety and efficacy of camrelizumab plus albumin paclitaxel and carboplatin in the neoadjuvant treatment of borderline resectable or unresectable locally advanced esophageal cancer. METHODS: A retrospective analysis was conducted on 27 patients with borderline resectable or unresectable locally advanced esophageal cancer who received neoadjuvant treatment with camrelizumab plus albumin paclitaxel and carboplatin at Shanxi Cancer Hospital from January 2020 to March 2022. Of these, 20 patients underwent thoracoscopic esophagectomy after neoadjuvant treatment. RESULTS: Overall, 88.9% (24/27) of patients completed neoadjuvant treatment. The objective response rate was 79.2% (19/24) according to the RECIST criteria. Of the 20 patients who underwent surgery, the R0 resection rate was 95%, and 35% (7/20) achieved pathological complete response (pCR). During neoadjuvant treatment, 30% (6/20) of patients experienced grade ≥3 treatment-related adverse events (TRAEs), and 20% (4/20) had grade ≥3 postoperative complications. There were no cases of reoperation or perioperative mortality. CONCLUSION: Camrelizumab plus albumin paclitaxel and carboplatin were found to be safe and effective in the neoadjuvant treatment of borderline resectable or unresectable locally advanced esophageal cancer. It was observed to improve the rate of curative resection without increasing perioperative complications.
