Physicians' perceptions of cancer care for elderly patients: a qualitative sociological study based on a pilot geriatric oncology program. 
The aim of this study was to document physicians' perceptions of cancer care for elderly patients within an oncogeriatric coordination pilot unit (UPCOG) created in Paris, France.  We focused on how physicians apply new cancer care practices, how they establish new teamwork, and their experience of oncogeriatrics in everyday practice.  Qualitative methods were used, including a literature review, observation of working sessions in the oncogeriatric pilot unit, and semi-structured interviews with 28 physicians.  The results show how physicians' differing perceptions of geriatric oncology can hinder routine collaboration.
