Aim: The aim of this study was to determine the relationship between supportive care needs and disease acceptance levels of patients with hematological cancer.

Material and Methods: This study was conducted as a descriptivecorrelational study. The study was conducted with 184 patients who received outpatient and inpatient chemotherapy at Hematology Department. The questionnaire form, the Short-Form Supportive Care Needs Survey Questionnaire, and the Acceptance of Illness Scale were used to collect the data. Ethics committee permission, institution permission, and written informed consent were obtained for the study. In evaluating the data, independent groups t-test, correlation analysis, and one-way analysis of variance were used together with the Tukey test.

Results: In the study, the mean score of Acceptance of the Illness was 26.8±7.0. The mean score of the psychological sub-dimension of the Supportive Care Needs Scale was 27.4±7.8; the health system sub-dimension mean score was 40.6±8.2; the physical subdimension mean score was 16.6±5.2; the patient care subdimension mean score was 12.7±3.6 and sexuality sub-dimension mean score was 7.4±3.4. It has been determined that supportive care needs are affected by sex, marital status, income level, social support perception, presence of chronic disease, metastasis status, and outpatient or inpatient treatment. The increase in the patients' psychological (r=-0.571) and physical care (r=-0.563) need scores decrease the patients' acceptance score of the disease by a moderate level.

Conclusion: It was found that as the patients' psychological and physical care needs increased, the disease acceptance level decreased. Considering these results, there is a need to conduct independent and comprehensive research for each type of hematology cancer at specific intervals to determine the patients' acceptance level and unmet care needs.
