There is little evidence regarding the effect of multidisciplinary care (MDC) on health outcomes across various cancer sites, including colon, rectal, and lung cancer. The current study addresses this gap by providing preliminary data regarding the relationship between MDC and selected processes and outcomes of care in NCCCP pilot sites. The long-term goal of this preliminary study is to generate effect sizes, establish feasibility, and build infrastructure to support the development of a larger more definitive study of MDC outcomes. The key aim of this pilot study is to determine the relationship between specific MDC assessment areas identified by a pre-existing MDC assessment tool (http://ncccp .cancer.gov /NCCCPMDC- Matrix- Tool. pdf ): case planning, physician engagement, coordination of care, infrastructure, financial, clinical trials and medical records, and each of the following outcomes [0] and processes [P]: 1) time to receipt of initial therapy[P]; 2) receipt of multi-modality therapy[O]; 3) evaluation for enrollment in a clinical trial[P]; 4) patient experience[O]; 5) adherence to NCCN treatment guidelines[P]; and 6) all-cause survival[O]. The study focuses on adult patients with an incident diagnosis of Stage III colon cancer, Stage II or III rectal cancer, or Stage III non-small cell lung cancer.
