Primary care physicians' perceptions concerning engagement in cancer survivor care.

Background: Given the growing diversity among cancer survivors and the fact that oncologists typically do not perform long-term care, the expected role of primary care physicians (PCPs) in survivor care is expanding. However, communication and collaboration between oncologists and PCPs are lacking. Therefore, we assessed the perception of cancer survivor care among PCPs. Methods: We sent a questionnaire to 767 Japanese Board-certified PCPs, regardless of facility type (clinics and hospitals), inquiring about PCPs' perceptions of their role in survivor care. Additionally, we included vignette-based scenarios focused on colorectal and prostate cancer survivors to explore factors associated with their clinical decisions. Results: We obtained 91 replies (response rate: 11.9%). A total of 75% of PCPs had encountered at least 1 cancer patient in actual practice. Even for patients actively receiving cancer treatment, >70% of PCPs reported that they were willing to engage in comprehensive survivor care, except for the administration of anticancer drugs. Further, 49% of PCPs considered that both PCPs and oncologists were suited to performing regular screening for cancer recurrence in high-risk patients. Multivariable logistic regression analyses revealed that clinic PCPs were less inclined to conduct screening for recurrence than hospital PCPs in both colorectal (odds ratio, 3.85 [95% confidence interval 1.40-10.6]) and prostate (4.36 [95% confidence interval 1.51-12.6]) cancer scenarios. Conclusions: Our findings suggest that Japanese PCPs are willing to engage in survivor care and encourage closer collaboration between oncologists and PCPs. However, oncologists might need to request cooperation, considering the facility type with which PCPs are affiliated.
