無雲夜空博點評挺靠譜，粗略查看了一下谷歌上的幾篇文章內容，大體上，的確是這樣的，不屬於歿亡最快的胰腺癌、肺癌一類。 普京的肛管鱗狀細胞癌，看上去像是屬於晚期的第四期，其中有三個因素：擴散轉移了；做過手術，不成功；他的醫療團隊診斷：活不過12個月。 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，局部肛門鱗狀細胞癌患者的 5 年總生存率 (OS) 預計為 78%，但在遠處轉移的患者中降至 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.結直腸癌：最常見的是直腸癌，往往表現為大便形狀改變、腹痛及便血等。經手術、放化療等綜合治療下5年生存率約50～78%。 https://www.xiaohe-jiankang.com/qa/70000000450005?ad=false 局限性肛門癌局限於肛門區域，原發腫瘤尚未擴散到周圍組織或遠處。所有肛門癌病例中只有約 48% 被這麼早診斷出來，但這個階段的肛門癌預後良好，存活率為 82%。區域性肛門癌是指肛門區域的癌症已經擴散到附近的組織和/或附近的淋巴結（III期）。在這個階段，該病的五年生存率為65%。遠處肛門癌是指癌症已經擴散到遠處器官，如肺或腦（IV 期），也稱為遠處轉移。IV期肛門癌預後最差，5年生存率為32%。總體而言，如果將所有三組結合起來，肛門癌的平均存活率為 68%。
