[A case of long-term survival by combined modality therapy for liver and pulmonary metastasis of rectal cancer].

We report a case of rectal cancer diagnosed in 2001, which enforced a rectal low anterior resection. Then, metastatic liver cancer and metastatic lung cancer recurred and we enforced an operation for both. Furthermore, metastatic lung cancer recurred again and enforced chemotherapy with radiation and systemic chemotherapy for approximately seven years. The metastatic lung cancer was reduced now in 2011, so that the chemotherapy has not been used since then. In our case, we mainly performed a surgical and radiation therapy for a local recurrent site therapy in the first half because we did not have much choice for a systemic chemotherapy like we have now. In the later half, we mainly performed a systemic chemotherapy to control the local recurrent site. A treatment policy for colon cancer recommends a surgical treatment by the guidelines, or even though chemotherapy has been developed at present, if a local therapy is practical. There were many cases where metastases had occurred right after surgery so a local site therapy by excision was good at all unconditionally. However, as a result of our case in a local site therapy combined with whole body chemotherapy, we report here that a long- term survival was obtainable. We also include a brief literature review.
