Impact of Disease Stage, Treatment Timing, and Demographic Disparities on Survival in Vulvar Squamous Cell Carcinoma Supplemental Materials

Supplemental Figure 3 (A-D): Demographic and Socioeconomic Disparities in VSCC Overall Survival (A) Kaplan-Meier survival curves illustrating survival differences by geographic location, with better survival in metropolitan areas. (B) Kaplan-Meier survival curves displaying survival outcomes stratified by income, highlighting significantly worse survival in lower-income groups. (C) Kaplan-Meier survival curves assessing survival by marital status, showing the best outcomes among married patients and the poorest outcomes among widowed patients. (D) Kaplan-Meier survival curves demonstrating survival differences by age, illustrating a steady decline in survival with increasing age, particularly after 50 years.

补充图3（A-D）：外阴鳞状细胞癌（Vulvar Squamous Cell Carcinoma，VSCC）总生存中的人口学与社会经济差异
(A) 卡普兰-迈耶生存曲线（Kaplan-Meier survival curves）展示了不同地理位置的生存差异，结果显示大都市地区患者的生存预后更优。
(B) 卡普兰-迈耶生存曲线按收入分层展示生存结局，结果明确提示低收入群体的生存情况显著更差。
(C) 卡普兰-迈耶生存曲线按婚姻状况评估生存预后，结果表明已婚患者的预后最佳，丧偶患者的预后最差。
(D) 卡普兰-迈耶生存曲线展示了不同年龄层的生存差异，结果显示随着年龄增长，生存率呈稳步下降趋势，尤其在50岁以后更为显著。
