A conceptual model of social networks and mechanisms of cancer mortality, and potential strategies to improve survival: an invited commentary.

In this article, the importance of social factors for cancer survivorship has been theoretically considered and empirically studied. This commentary and Kroenke's narrative review highlight how social network theory and methods may innovatively expand this substantive body of work. First, we add to a new understanding of cancer survivorship through: (a) discussing the delineation and differences between multiple social factors of interest across existing conceptual models; (b) characterizing their relationships to each other and to cancer survivorship through a social network lens; and (c) overall, sharing terminology and strengthening connections within this diverse body of literature. Second, we note opportunities for future research in terms of (a) simultaneous measurement of multiple social factors at different levels and (b) adaptation of designs to leverage and measure the theorized mechanisms. This commentary describes how incorporation of social network research can optimize research, practice, and policy contributions regarding cancer survival and survivorship.
