Partnered status and receipt of guideline-concordant adjuvant chemotherapy among patients with colon cancer.

In this innovative investigation of the associations between partnered status and specific attributes of curative-intent chemotherapy, approximately 35% of patients terminated chemotherapy early. Having a partner increased the odds of completing therapy, which may be one mechanism through which having a partner improves disease-specific outcomes among patients with colon cancer. Identifying those aspects of partner support that can be reproduced with community or clinical personnel may help unpartnered patients to complete the recommended course of curative-intent chemotherapy.
