Assessment of the Prevalence of Sarcopenia in Early Palliative Cancer Patients
Assessment of the Prevalence of Sarcopenia in Early Palliative Cancer Patients
Cancer is one of the leading causes of death in the world after cardiovascular disease (8.7 million deaths in 2015 for 17.5 million cases) 1. Despite a great deal of progress in disease detection and treatment, the incidence of cancer is steadily increasing (+ 33% in 2015) and particularly in certain locations (pancreas, lungs, brain and stomach), including risk factors are not always identified.
Advanced stage cancer (= metastatic) is most often incurable with the exception of germ cell tumors. Palliative care is then most often offered. Palliative care favors the patient's quality of life as a whole (medical, physical, psychological and social).
The symptoms most often reported by patients are: pain, fatigue, decreased appetite, nausea, and are directly related to phenomena such as cachexia, loss of autonomy and deterioration of psychological state, resulting in decreased overall survival. Chemotherapies and targeted therapies (immunotherapy, hormonal therapy, participation in a clinical trial) can provide a benefit in quality of life and survival only in the early phase (little benefit in the terminal phase).
Other prognostic factors can impact the quality of life and overall survival in these situations: sarcopenia and disorders of nutritional status (obesity, undernutrition).
The study of sarcopenia by CT scan of patients in a palliative situation is still too scarce. Sarcopenia is an often underestimated event and is associated with older age, co-morbidities, increased infectious complications, and early mortality.
The study of the prevalence of sarcopenia by CT scan would confirm its prognostic impact in a palliative situation.
