Control of Primary Lesions Using Resection or Radiotherapy Can Improve the Prognosis of Metastatic Colorectal Cancer Patients

摘要

Background: Control of the primary lesions in metastatic colorectal cancer (mCRC) is still controversial. For rectal cancer patients, not only resection but also irradiation is expected to provide palliative effects. We investigated the effects of resection and irradiation of primary lesions (local control) on the prognosis of mCRC patients.
