e19522 Background: Japanese physicians’ attitudes regarding the health care needs of childhood cancer survivors (CCSs) are not well described. Thus we examined the self-reported preferences and knowledge of pediatric oncologists and surgeons concerning this population. Methods: A mailed survey was sent to 858 physician members of the Japanese Society of Pediatric Oncology in October 2010 according to the methods of Henderson et al (JCO 28 (5):878, 2010). Results: A total of 405 surveys were returned (47% response rate); of which 300/533 pediatric oncologists and 105/325 and surgeons responded, respectively. Respondents’ median age was 46 and 48 years, respectively; 79% and 84% men. There were no differences between physicians excluding living area distributions and educational opportunities of late effects. Less than one third of respondents (31%) report referring survivors to other physicians. When comfort levels in caring for CCSs were described (1 = very uncomfortable; 7 = very comfortable), physicians were most comfortable with CCS <= 21years (4.4 ± 1.3 and 3.8±1.4), less comfortable with CCSs > 21 years but < 30 years old (3.6 ± 1.4 and 3.6 ± 1.4), and least comfortable with CCS >30 years (2.8 ± 1.5 and 3.3 ± 1.6). Familiarity with long-term follow-up guidelines was quite lower in surgeons (2.8 ± 1.4 vs 1.5 ± 1.4). In response to a clinical vignette of a 25 year old woman treated at 1 year with prophylactic cranial radiation (24 Gy), 62 % of pediatric oncologists and 43% of surgeons answered 3 or more questions regarding follow-up frequency, Hepatitis C surveillance, and late effects of cranial radiation in concordance with Japanese recommendations. Logistic regression analysis limited to pediatric oncologists showed learning experience (OR= 1.75; 95% CI, 1.05 to 2.93); practicing in a children’s hospital (OR 5.11; 95% CI, 1.15 to 22.8); and practicing in a general hospital (OR, 0.55; 95% CI, 0.32 to 0.95) were associated with answering three or more questions correctly. Conclusions: Preferences and knowledge with regard to long-term follow-up care of CCSs differ between pediatric oncologists and surgeons in Japan; pediatric oncologists appear to be more comfortable.
