Hemato-oncology patients undergoing intensive chemotherapy treatments experience different types of symptoms during and after treatments, which are often refractory to the established therapy. Physical symptoms such as pain, dyspnea, mucositis, insomnia, loss of appetite, constipation and diarrhea, among others, have a huge impact on quality of life, temporarily until symptomatic control, but also permanently with the development of anxiety, depression, long-term fatigue and post-traumatic stress. As recommended by ASCO (American Society of Clinical Oncology), the palliative approach to oncological diseases must be as early as possible and be part of the "standard of care". However, the lack of concrete data on this topic in the last decade served as a barrier to the early integration of this same care for hemato-oncology patients in its various areas. Palliative care presupposes global, interdisciplinary action, carried out by specific teams that must act in situations of incurable or serious illness, in an advanced and progressive phase. The potential benefits can be countless and of significant importance, from the impact on quality of life, symptomatic control, reduction of anxiety and depression and even the promotion of informed and conscious choices at the end of life as well as the reduction of aggressive strategies. used at this stage of the disease.

Hematological diseases are biologically complex and constitute a group of oncological pathologies in which the acute disease has an unpredictable course and can reach different outcomes quickly. Patients often experience rapid and not always predictable progression during their treatment trajectory and at the end of life. Unlike most advanced solid tumors, the possibility of cure remains an objective even in situations of relapse or refractory disease. Hemato-oncology patients undergoing intensive chemotherapy treatments experience different types of symptoms during and after treatments, which are often refractory to the established therapy. Physical symptoms such as pain, dyspnea, mucositis, insomnia, loss of appetite, constipation and diarrhea, among others, have a huge impact on quality of life, temporarily until symptomatic control, but also permanently with the development of anxiety, depression, long-term fatigue and post-traumatic stress. As recommended by ASCO (American Society of Clinical Oncology), the palliative approach to oncological diseases must be as early as possible and be part of the "standard of care". However, the lack of concrete data on this topic in the last decade served as a barrier to the early integration of this same care for hemato-oncology patients in its various areas. There are still many specific needs that have not been identified, especially in the initial approach to acute illness. Palliative care presupposes global, interdisciplinary action, carried out by specific teams that must act in situations of incurable or serious illness, in an advanced and progressive phase. The palliative approach can begin with palliative actions carried out by professionals without specific training so that, in inpatient or outpatient settings, the negative repercussions of the disease can be reduced on the various aspects of the patient: physical, psychological, social and spiritual. To this end, palliative interventions must be developed and defined based on the greatest needs of this population and the timing of the disease, not just at the end of life. The potential benefits can be countless and of significant importance, from the impact on quality of life, symptomatic control, reduction of anxiety and depression and even the promotion of informed and conscious choices at the end of life as well as the reduction of aggressive strategies. used at this stage of the disease.

The still scarce knowledge among hematologists about the benefits of palliative care in this population has represented an important barrier. In intensive chemotherapy, area of palliative care that have been little intervened, there seems to be an enormous potential for benefit with these interventions given the complexity of physical and psychological symptoms involved, with "cure" being the main objective. Our aim is to evaluate the effect of early follow-up by the palliative care team compared to conventional treatment by the Hematology team, where this referral is made only in specific cases.
