title: [Controversy of primary tumor resection for stage IV colorectal cancer].
abstract: Primary tumor resection (PTR) is currently recommended for patients with unresectable stage IV colorectal cancer (CRC) who present symptoms related to their primary tumor (eg, obstruction, perforation, significant bleeding). The role of PTR in asymptomatic patients remains controversial. This article will review the role of PTR in incurable stage IV CRC, including the advantages and risks, with emphasis on identifying patients who may benefit from this palliative intervention.
