Abstract:
Objective Brain metastasis(BM) is unusual in colorectal carcinoma(CRC) patients.This study was to evaluate the characteristics and prognosis of brain metastasis of colorectal carcinoma patients.Methods Twenty-eight consecutive CRC patients underwent surgical resection for BM between January 2001 and December 2008.The clinical data were analyzed by univariate (logrank) and Cox regression test.Results The median age at BM diagnosis from CRC was 57 years(41-75 years).Median survival after neurosurgical intervention was 9.4 months.The 1-year and 5-year survival rates were 28.9%and 7.1%,respectively.Seventeen patients(61%)had concurrent systemic metastasis.All patients were symptomatic with neurologic deficits and symptoms.On multivariate analysis,gender,infratentorial location of lesions and characteristics of primary CRC had no significant impact on survival.Two factors were signitlcandy associated with better survival:single brain metastases and absence of extracranial metastases.Perioperative mortality was zero.There were no difference of survival among patients undergoing resection alone and resection combined with whole brain radiotherapy (WBRT) or stereotactic radiosurgery(SRS). Conclusions Brain metastases from colorectal cancer is an evil omen of poor prognosis of CRC patients.Sursical resection of symptomatic brain metastases from colorectal cancer is relatively safe and provides the opportunity for prolonged survival.
