Introduction: The Spanish National Health System has defined complexity as a set of factors of increased difficulty that require the intervention of a palliative care team . Palliative care aims to improve the quality of life of patients with chronic terminal illnesses. This study aims to describe the degree of complexity of cancer patients in palliative care, to determine which elements of complexity are most prevalent and to determine which other hospital clinical factors are associated with the level of complexity., Methods: This study is a descriptive, observational, and cross-sectional analysis that included patients diagnosed with advanced oncological pathology undergoing palliative treatment who were admitted to the Medical Oncology ward of the Miguel Servet University Hospital between March and April 2023., Result: A total of 100 patients were selected for the study. According to the IDC-Pal, 68% of patients were classified as highly complex, 26% of patients were complex and only 6% of patients were classified as non-complex. The presence of pain ( P < .001), nausea and vomiting ( P = .027), depression ( P = .033) and functional status ( P = .011) were statistically independent predictors of high complexity., Discussion: This study has shown that a high proportion of hospitalized palliative care cancer patients have high complexity, suggesting a good matching of healthcare resources to patient complexity. Four factors related to complexity have been identified, namely pain, nausea and vomiting, depression and a bedridden functional state. The presence of any of the 4 factors could help healthcare professionals to identify patients for early specialized palliative care., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Spontaneous remission (SR) is defined as the complete or partial disappearance of a diagnosed malignant disease in the absence of known active medical treatment. The role of the immune system is thought to be important, but has not yet been elucidated. On this matter, there are studies that suggest that the abscopal effect (AE), which is defined as the remission of untreated lesions beyond the irradiated area, may be explained by the activation of a systemic immune response against the tumor. Sclerosing epithelioid fibrosarcoma (SEF) is a rare variant of soft tissue sarcoma that is characterized by a slow evolution, with local recurrences and late metastases. The treatment is based on surgery, leaving a minimal role to chemotherapy (ChT) and radiotherapy (RT) for metastatic unresectable disease, and no cases of SR have been reported in the literature so far., Case Description: We present the case of a patient with a lung metastatic recurrence of SEF, diagnosed and treated with surgery 8 years before. After progression to pazopanib and other ChT drugs, because of the chest pain associated with a pleural mass invading the second costal arch, the patient received antalgic local RT treatment. Months later, and without any further treatment, a partial remission of all the tumoral lesions was presented, and she is alive 25 years after the first diagnosis., Conclusions: As far as reported in the literature, this is the first case of SR in SEF. Among the possible causes of this SR, we think that the most plausible is that palliative treatment with RT of the pleural mass induced an AE, leading to a reduction of all tumoral lesions, even those outside the irradiated region., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tcr.amegroups.com/article/view/10.21037/tcr-23-2276/coif).
