一点建议

据说，肠癌越是年纪大的发展得反倒快。二期做化疗日后复发可能性比不做要低一些，但也没有很明显的改善，所以，具体看病人的身体状况。

以下是google找来的：

Chemotherapy

You may be offered chemotherapy after surgery (called adjuvant chemotherapy) for stage 2 colon cancer to reduce the risk of recurrence. Chemotherapy can be started 4–8 weeks after surgery and is usually given for 6 months.

Most people with stage 2 colon cancer will not need chemotherapy. Chemotherapy is only offered when there is a high risk that the colon cancer will recur (come back) and at least one of the following high-risk features is present:

    The tumour is T4 (stage 2B or 2C).
    Less than 12 lymph nodes were removed or could be assessed.
    The tumour has grown into nearby lymph nodes or blood vessels, the membrane that covers and supports most of the organs in the abdomen (called the visceral peritoneum) or the space surrounding nerves (called perineural invasion).
    The tumour is high grade, or poorly differentiated.
    A blockage in the intestine (called bowel obstruction).
    A tear or hole in the intestine (called bowel perforation).
    Not enough healthy tissue was removed along with the tumour.
    Cancer cells are found in the tissue removed along with the tumour (called positive surgical margins).
