Data were collected between March and September of 2016, through the evaluation of the medical records of 43 patients who underwent HSCT and developed some type of psychological distress. Among 43 patients with psychological disorders, 51.16% were female, 62.79% developed anxiety 32.56% developed insomnia and 20.93% developed depression. Of these, 27.91% had a main diagnosis indicating the transplantation of Multiple Myeloma (MM), and 58.14 received autologous transplantation. It was observed that the patient had psychological suffering from the diagnosis until the end.
