This study aimed to identify the clinical characteristics of hypopharyngeal squamous cell carcinoma (HPSCC) patients with multiple primary cancers (MPCs) and to compare differences between patients with metachronous and synchronous MPCs.
This study included 219 patients with HPSCC treated at our center between 2008 and 2020; the clinical characteristics and prognosis of 66 patients with MPCs were analyzed. Propensity score matching (PSM) was used to balance the factors between patients with synchronous and metachronous MPCs.
Sixty-six patients with HPSCC (66/219, 30.1%) experienced MPCs, of which 29 were synchronous and 37 were metachronous. The esophagus (n = 39, 59.1%), lung (n = 10, 15.2%), and oropharynx (n = 4, 6.1%) were the three most common sites of MPCs in both the synchronous and metachronous groups. More patients with synchronous MPCs were stage T1-2 (82.8% vs. 59.5%, P = 0.041) compared to those with metachronous MPCs. Among the 24 pairs of patients after PSM, patients with metachronous MPCs had higher 3-year progression-free survival (PFS) (52.5% vs. 16.3%, P < 0.001) and overall survival (OS) (58.5% vs. 22.1%, P = 0.001) than those with synchronous cancers. Multivariate Cox analysis showed that patients with synchronous MPCs had shorter PFS (HR 4.45, 95% CI 1.819-10.885, P = 0.001) and OS (HR 3.918, 95% CI 1.591-9.645, P = 0.003).
MPCs are common among patients with HPSCC, and patients with metachronous MPCs had better survival than those with synchronous MPCs. Clinicians should be aware of the possibility of MPCs in patients with HPSCC and optimize treatment to improve outcomes.
本研究旨在确定患有多原发癌(MPC)的下咽鳞状细胞癌(HPSCC)患者的临床特征,并比较同时性和异时性 MPC 患者之间的差异。
本研究纳入了 2008 年至 2020 年间在我中心治疗的 219 例 HPSCC 患者,分析了 66 例 MPC 患者的临床特征和预后。采用倾向评分匹配(PSM)平衡同时性和异时性 MPC 患者之间的因素。
219 例 HPSCC 患者中有 66 例(66/219,30.1%)发生了 MPC,其中 29 例为同时性 MPC,37 例为异时性 MPC。食管(n=39,59.1%)、肺(n=10,15.2%)和口咽(n=4,6.1%)是同时性和异时性 MPC 中最常见的三个部位。与异时性 MPC 患者相比,更多的同时性 MPC 患者为 T1-2 期(82.8% vs. 59.5%,P=0.041)。在 24 对经过 PSM 后的患者中,异时性 MPC 患者的 3 年无进展生存率(PFS)(52.5% vs. 16.3%,P<0.001)和总生存率(OS)(58.5% vs. 22.1%,P=0.001)均高于同时性癌症患者。多变量 Cox 分析显示,同时性 MPC 患者的 PFS(HR 4.45,95%CI 1.819-10.885,P=0.001)和 OS(HR 3.918,95%CI 1.591-9.645,P=0.003)更短。
MPC 是 HPSCC 患者中常见的情况,异时性 MPC 患者的生存情况优于同时性 MPC 患者。临床医生应意识到 HPSCC 患者发生 MPC 的可能性,并优化治疗以改善预后。
