无云夜空博点评挺靠谱，粗略查看了一下谷歌上的几篇文章内容，大体上，的确是这样的，不属于殁亡最快的胰腺癌、肺癌一类。 普京的肛管鳞状细胞癌，看上去像是属于晚期的第四期，其中有三个因素：扩散转移了；做过手术，不成功；他的医疗团队诊断：活不过12个月。 Moreover, patients with localized anal squamous cell carcinoma are expected to have a 5-year overall survival (OS) rate of 78%, but it drops to 19% in patients with distant metastasis [4, 5]. 此外，局部肛门鳞状细胞癌患者的 5 年总生存率 (OS) 预计为 78%，但在远处转移的患者中降至 19% [ 4, 5 ]。 https://surgicalcasereports.springeropen.com/articles/10.1186/s40792-022-01474-x#:~:text=However%2C%20the%20standard%20treatment%20for,metastasis%20%5B4%2C%205%5D. Localized anal cancer is confined to the anal area, and the primary tumor has not spread to surrounding tissues or to distant regions. Only about 48% of all anal cancer cases are diagnosed this early, but the anal cancer prognosis at this stage is good with a survival rate of 82%.Regional anal cancer refers to cancer in the anal region that has spread to nearby tissues and/or nearby lymph nodes (Stage III). At this stage, the disease has a five-year survival rate of 65%.Distant anal cancer is when the cancer has spread to distant organs such as the lungs or brain (Stage IV), which is also called distant metastases. The anal cancer prognosis is worst in Stage IV with a five-year survival rate of 32%.Overall, if all three groups are combined the average survival rate for anal cancer is 68%. https://www.immunitytherapycenter.com/blog/what-is-the-survival-rate-for-anal-cancer-2/ 5.结直肠癌：最常见的是直肠癌，往往表现为大便形状改变、腹痛及便血等。经手术、放化疗等综合治疗下5年生存率约50～78%。 https://www.xiaohe-jiankang.com/qa/70000000450005?ad=false 局限性肛门癌局限于肛门区域，原发肿瘤尚未扩散到周围组织或远处。所有肛门癌病例中只有约 48% 被这么早诊断出来，但这个阶段的肛门癌预后良好，存活率为 82%。区域性肛门癌是指肛门区域的癌症已经扩散到附近的组织和/或附近的淋巴结（III期）。在这个阶段，该病的五年生存率为65%。远处肛门癌是指癌症已经扩散到远处器官，如肺或脑（IV 期），也称为远处转移。IV期肛门癌预后最差，5年生存率为32%。总体而言，如果将所有三组结合起来，肛门癌的平均存活率为 68%。
