In this study we try to investigate the Health Professionals'(HPs) training needs in a sector of Primary Health Care which is the Long-term care services for oncology patients in Greece, in order to improve the care services provided as well as the cooperation with the carers and families. This qualitative study used semi-structured interviews and thematic analysis. In two major Oncology Hospitals of Athens-Greece seventeen HPs from the corresponding medical/nursing staff dedicated to oncology patients, were recruited. The transcripts were analyzed thematically. All HPs confirmed their need for further training in all areas such as new drugs and technologies, communication techniques for psychosocial support to patients, issues concerning the quality of life of oncology patients. The HPs underlined their need for information training, required particularly by younger HPs and for emotional support through group meetings. Some specific conclusions were related to learning grief management skills and health economics. A common request was the provision for training in the operation of a well-organised interdisciplinary team. Further and better targeted training has been recognized as essential in order to improve the quality home care services and this has been a common requirement expressed by both HPs and oncology patients who are the intended recipients of home nursing care.
