Most people with stage IV cancer will get chemo and/or targeted therapies to control the cancer. Some of the most commonly used regimens include:
FOLFOX: leucovorin, 5-FU, and oxaliplatin (Eloxatin) FOLFIRI: leucovorin, 5-FU, and irinotecan (Camptosar) CAPEOX or CAPOX: capecitabine (Xeloda) and oxaliplatin FOLFOXIRI: leucovorin, 5-FU, oxaliplatin, and irinotecan One of the above combinations plus either a drug that targets VEGF, (bevacizumab [Avastin], ziv-aflibercept [Zaltrap], or ramucirumab [Cyramza]), or a drug that targets EGFR (cetuximab [Erbitux] or panitumumab [Vectibix])
The choice of regimens depends on several factors, including any previous treatments you’ve had and your overall health.
If one of these regimens is no longer working, another may be tried. For people with certain tumor changes in the MMR genes, another option after initial chemotherapy might be treatment with an immunotherapy drug such as pembrolizumab (Keytruda) or nivolumab (Opdivo).
5-FU and leucovorin, with or without a targeted drug Capecitabine, with or without a targeted drug Irinotecan, with or without a targeted drug

估计医生认为现有的治疗方法对他作用不大，以色列正在进行的什么clinical trial会对他有帮助吧。
楼主问的应该是治愈，你说的是延长寿命若干年（月）。
很难完全治愈。在美国，美国四期结肠癌五年存活率大约在14%，比肺癌的2%要高很多。
最好的结果是尽可控制发展，共存。
