While the prognosis of patients with partial SRCC (PSRCC) has been rarely reported, colorectal signet-ring cell carcinoma (SRCC) has been associated with poor prognosis. The aim of this study was to analyze the prognosis of patients with different SRCC composition and establish a prediction model. A total of 91 patients with SRC component were included in the study. These patients were divided into two groups: SRCC group (SRC composition > 50%; n=41) and partial SRCC (PSRCC) group (SRC composition ≤ 50%; n=50). COX regression model was used to identify independent prognostic factors for overall survival (OS). A predictive nomogram was established and compared with the 7th AJCC staging system. After a median follow-up of 16 months, no significant difference in OS was observed in either group. Preoperative carcinoembryonic antigen (CEA) level, pN stage, M stage, preoperative ileus, and adjuvant chemotherapy were independent prognostic risk factors for OS (p<0.05). A nomogram for predicting the overall survival of colorectal SRCC was established with a C-index of 0.800, and it showed better performance than that of the 7th AJCC staging system (p<0.001). In summary, the ratio of SRC component was not an independent prognostic factor of the OS. Those patients with less than 50% of SRC component should be given the same clinical attention. A predictive nomogram for survival based on five independent prognostic factors was developed and showed better performance than the 7th AJCC staging system. This resulted to be helpful for individualized prognosis prediction and risk assessment.

结直肠癌不同比例印戒细胞的预后意义。

虽然很少报道部分 SRCC (PSRCC) 患者的预后,但结直肠印戒细胞癌 (SRCC) 与预后不良有关。本研究旨在分析不同SRCC成分患者的预后并建立预测模型。共有 91 名具有 SRC 成分的患者被纳入研究。这些患者分为两组:SRCC 组(SRC 组成> 50%;n=41)和部分SRCC(PSRCC)组(SRC 组成≤50%;n=50)。COX 回归模型用于确定总生存期 (OS) 的独立预后因素。建立预测列线图并与第 7 次 AJCC 分期系统进行比较。中位随访 16 个月后,两组的 OS 均未观察到显着差异。术前癌胚抗原(CEA)水平,pN分期、M分期、术前肠梗阻和辅助化疗是OS的独立预后危险因素(p<0.05)。建立了预测结直肠 SRCC 总生存期的列线图,其 C 指数为 0.800,其表现优于第 7 次 AJCC 分期系统(p<0.001)。总之,SRC成分的比率不是OS的独立预后因素。那些 SRC 成分少于 50% 的患者应给予同样的临床关注。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。和辅助化疗是 OS 的独立预后危险因素 (p<0.05)。建立了预测结直肠 SRCC 总生存期的列线图,其 C 指数为 0.800,其表现优于第 7 次 AJCC 分期系统(p<0.001)。总之,SRC成分的比率不是OS的独立预后因素。那些 SRC 成分少于 50% 的患者应给予同样的临床关注。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。和辅助化疗是 OS 的独立预后危险因素 (p<0.05)。建立了预测结直肠 SRCC 总生存期的列线图,其 C 指数为 0.800,其表现优于第 7 次 AJCC 分期系统(p<0.001)。总之,SRC成分的比率不是OS的独立预后因素。那些 SRC 成分少于 50% 的患者应给予同样的临床关注。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。并且表现出比第 7 次 AJCC 分期系统更好的性能(p<0.001)。总之,SRC成分的比率不是OS的独立预后因素。那些 SRC 成分少于 50% 的患者应给予同样的临床关注。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。并且表现出比第 7 次 AJCC 分期系统更好的性能(p<0.001)。总之,SRC成分的比率不是OS的独立预后因素。那些 SRC 成分少于 50% 的患者应给予同样的临床关注。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。开发了基于五个独立预后因素的生存预测列线图,并显示出比第 7 次 AJCC 分期系统更好的性能。这有助于个体化预后预测和风险评估。
