Impact of Primary Tumour Location and Early Tumour Shrinkage on Outcomes in Patients with RAS Wild-Type Metastatic Colorectal Cancer Following First-Line FOLFIRI Plus Panitumumab.

ABSTRACT:

Objective

Data from a trial of first-line panitumumab plus FOLFIRI (folinic acid, infusional 5-fluorouracil and irinotecan) in metastatic colorectal cancer were retrospectively analysed to investigate the effects of primary tumour location and early tumour shrinkage on outcomes.

Methods

Patients with RAS wild-type metastatic colorectal cancer from a single-arm, open-label phase II study (NCT00508404) were included. Tumours located from the splenic flexure to rectum and in the caecum to transverse colon were defined as left- and right-sided, respectively. Baseline characteristics were summarised by primary tumour location and the effects of primary tumour location on outcomes-including objective response rate, resection rate, depth of response, duration of response and progre
