Onco-nephrology: Physicians’ Expectations About a New Subspecialty

Introduction Renal events are common in cancer patients and malignancy is a prevalent complication in both patients transplanted and under kidney replacement therapy (KRT). In recent years, onco-nephrology has been developed as a subspecialty whose scope has not been well established yet. The aim of our study was to assess resident and senior physicians’ knowledge and expectations about onco-nephrology. Methods and Materials Two anonymous self-administered online questionnaires were developed by a multidisciplinary team and distributed to French residents and senior physicians. Results Two hundred twenty-eight physicians answered the survey, including 128 (56%) nephrologists, of which 98 (43%) were senior physicians and 130 (57%) were residents. Nephrologists rated their confidence in their ability to face onco-nephrological situation at 6/10 (interquartile range (IQR) 4.0–7.0) and oncologists at 6.0/10 (5.0–7.0). Managing cancer drugs in patients on KRT or in transplanted patients and discussion about introducing dialysis in cancer patients were designated as the most challenging topics. Asking if they had received appropriate learning, residents’ median agreement was ranked at 3.0/10 (2.0–4.0). Forty-six percent of the respondents considered available resources as not appropriate. Specialized onco-nephrology consultations were accessible for 21% of the respondents. Finally, respondents thought there is a strong need for a national working group (8.3/10) with 87% of them expecting new reliable guidelines. Conclusion The present survey revealed physicians’ expectations about onco-nephrology implementation in France. An appropriate answer could be the creation of a national working group. Therefore, GRIFON (Groupe de Recherche Interdisciplinaire en OncoNéphrologie) has recently been created.
