Real-world management and outcomes of older patients with locally advanced esophageal squamous cell carcinoma: a multicenter retrospective study
BMC cancer(2023)
摘要
Background Neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for locally advanced esophageal squamous cell carcinoma (ESCC). Chemoradiotherapy (CRT) is an alternative treatment approach. However, both treatments are associated with toxicity, and the optimal treatment for older patients with ESCC is unknown. This study aimed to evaluate the treatment strategies and prognosis of older patients with locally advanced ESCC in a real-world setting. Methods We retrospectively evaluated 381 older patients (≥ 65 years) with locally advanced ESCC (stage IB/II/III, excluding T4) who received anticancer therapy at 22 medical centers in Japan. Based on age, performance status (PS), and organ function, the patients were classified into two groups: clinical trial eligible and ineligible groups. Patients aged ≤ 75 years with adequate organ function and a PS of 0–1 were categorized into the eligible group. We compared the treatments and prognoses between the two groups. Results The ineligible group had significantly shorter overall survival (OS) than the eligible group (hazard ratio [HR] for death, 1.65; 95% confidence interval [CI], 1.22–2.25; P = 0.001). The proportion of patients receiving NAC followed by surgery was significantly higher in the eligible group than in the ineligible group ( P = 1.07 × 10 –11 ), whereas the proportion of patients receiving CRT was higher in the ineligible group than in the eligible group ( P = 3.09 × 10 –3 ). Patients receiving NAC followed by surgery in the ineligible group had comparable OS to those receiving the same treatment in the eligible group (HR, 1.02; 95% CI, 0.57–1.82; P = 0.939). In contrast, patients receiving CRT in the ineligible group had significantly shorter OS than those receiving CRT in the eligible group (HR, 1.85; 95% CI, 1.02–3.37; P = 0.044). In the ineligible group, patients receiving radiation alone had comparable OS to those receiving CRT (HR, 1.13; 95% CI, 0.58–2.22; P = 0.717). Conclusions NAC followed by surgery is justified for select older patients who can tolerate radical treatment, even if they are old or vulnerable to enrollment in clinical trials. CRT did not provide survival benefits over radiation alone in patients ineligible for clinical trials, suggesting the need to develop less-toxic CRT.
