colorectal cancer (cRc) treatment is associated with a high morbidity which may result in a reduced health-related quality of life (HRQoL). the pre-operative measurement of handgrip strength (HGS) might be a tool to predict the patient's outcome after cRc surgery. the aim of this study was to evaluate the association of pre-operative HGS with the occurrence of postoperative complications and postoperative HRQoL. Stage I to III CRC patients ≥ 18 years were included at diagnosis. Demographic and clinical data as well as HGS were collected before start of treatment. HGS was classified as weak if it was below the gender-specific 25th percentile of our study population; otherwise HGS was classified as normal. The occurrence of postoperative complications within 30 days after surgery was collected from medical records. Cancer-specific HRQoL was measured 6 weeks after treatment using the EORTC QLQ-C30 and the EORTC QLQ-CR29 questionnaire. Of 295 patients who underwent surgical treatment for CRC, 67 (23%) patients had a weak HGS while 228 (77%) patients had normal HGS. 118 patients (40%) developed a postoperative complication. Complications occurred in 37% of patients with a weak HGS and in 41% of patients with a normal HGS (p = 0.47). After adjustment for age, sex, ASA, BMI and TNM, no significant associations between pre-operative HGS and the occurrence of postoperative complications and between HGS and HRQoL were found. We conclude that a single pre-operative HGS measurement was not associated with the occurrence of postoperative complications or posttreatment HRQoL in stage i-iii cRc patients. Colorectal cancer (CRC) is the second commonest cause of cancer death in the Netherlands 1. The number of CRC patients has increased during the past years from 9,106 newly diagnosed patients in 2000 to 15,807 in 2015 2. Up to high age, the vast majority of these patients undergo surgical resection for cure or palliation 3. Unfortunately, CRC surgery is associated with a high complication rate up to 50%, associated with a reduced health-related quality of life (HRQoL), increased hospital costs and even mortality 4,5. Despite the introduction of laparoscopic surgery and the implementation of the Enhanced Recovery After Surgery (ERAS) protocol, certain groups with pre-existent comorbidity and a reduced functional capacity are known to be at risk for the occurrence of postoperative adverse events 6. Preoperative risk stratification remains challenging as the tools used for the risk stratification mainly use traditional and costly examinations such as cardiac and pulmonary functioning and laboratory tests 7. Apart from these examinations, which provide mainly anaesthesiological information on the risk of perioperative adverse events and not outcome after the end of treatment, there is a need for an easy tool
