Purpose: Disparities in access to a multidisciplinary cancer consultation (MDCc) persist, and the role of physician relationships remains understudied. This study examined the extent to which multilevel factors, including patient characteristics and patient-sharing network measures reflecting the structure of physician relationships, are associated with an MDCc and receipt of stereotactic body radiation therapy versus surgery among patients with early-stage non-small cell lung cancer (NSCLC).
Methods And Materials: In this cross-sectional study, we analyzed Surveillance, Epidemiology, and End Results (SEER)-Medicare data for patients diagnosed with stage I-IIA NSCLC from 2016 to 2017.

Article Synopsis
- The study explored the impact of being treated by "linchpin" physicians—doctors with fewer connections to other specialists—on cancer survival rates among patients with non-small cell lung cancer and colorectal cancer.
- Analyzed data from 10,081 lung cancer and 9,036 colorectal cancer patients revealed that those treated by linchpin radiation oncologists had a 17% higher mortality risk, while linchpin surgeons for CRC had a 22% greater risk.
- The findings suggest that patients treated by these linchpin physicians had worse survival outcomes, indicating a need for better access to multidisciplinary cancer care.

Importance: Physician headcounts provide useful information about the cancer care delivery workforce; however, efforts to track the oncology workforce would benefit from new measures that capture how essential a physician is for meeting the multidisciplinary cancer care needs of the region. Physicians are considered linchpins when fewer of their peers are connected to other physicians of the same specialty as the focal physician. Because they are locally unique for their specialty, these physicians' networks may be particularly vulnerable to their removal from the network (eg, through relocation or retirement).

Radiotherapy is a linchpin in head and neck squamous cell carcinoma (HN-SCC) treatment. Modulating tumour and/or normal tissue biology offers opportunities to further develop HN-SCC radiotherapy. The microbiota, which can exhibit homeostatic properties and be a modulator of immunity, has recently received considerable interest from the Oncology community.
