Efficacy and safety of pembrolizumab plus albumin-bound paclitaxel and nedaplatin as a first-line therapy for advanced esophageal squamous cell carcinoma. (English)

Objective: To observe the clinical efficacy and safety of pembrolizumab plus albumin-bound paclitaxel and nedaplatin as a first-line therapy in patients with advanced esophageal squamous cell carcinoma (ESCC). Methods: 35 patients with advanced ESCC and evaluable foci admitted in Changhai Hospital from March 2020 to September 2021 were included in this study. All patients were given pembrolizumab 200 mg and albumin-bound paclitaxel 130 mg/m² on day 1 and 8, and nedaplatin 70 mg/m² on day 1. The treatment was repeated every 21 days. Evaluation of tumor response was performed according to Response Evaluation Criteria in Solid Tumors 1.1 (RECIST1.1). Adverse effects were graded using version 5.0 of the National Cancer Institute Common Toxicity Criteria (NCI-CTC). Results: All 35 patients were available for evaluation, with 4 patients (11.4%) achieving complete response (CR), 21 patients (60.0%) partial response (PR), 10 patients (28.6%) stable disease (SD) and 0 patients progression disease (PD). The objective response rate (ORR) was 71.4%. The disease control rate (DCR) was 100%. The median progression free survival (PFS) was 13.4 months. The main adverse effects include bone marrow suppression, thyroid dysfunction, rash, fever, arthralgia, myalgia and alopecia. Treatment-related adverse events of grade 3 or higher occurred only in 3 patients (8.6%). Conclusion: Pembrolizumab plus albumin- bound paclitaxel and nedaplatin as a first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety in patients with advanced ESCC. Randomized trials with expanded samples to evaluate this new combination strategy are warranted. [ABSTRACT FROM AUTHOR]
