Abstract

BackgroundSarcopenia is associated with physical disability, increased post-operative complications, poorer tolerance to chemotherapy, and reduced survival outcome. However, little is known about the changes in body composition during chemotherapy treatment. We aimed to determine whether adjuvant or palliative chemotherapy causes the development of sarcopenia in newly diagnosed cancer patients and to reveal the relationship of sarcopenia with the duration of chemotherapy.MethodsThe study included newly diagnosed cancer patients who underwent curative surgery for primary tumor and also cancer patients who were metastatic at diagnosis. Body composition and handgrip strength were assessed by bio-electric impedance analysis (BIA) and handgrip dynamometer tools, respectively. Measurement tests were performed prior to chemotherapy, in the third and sixth months of chemotherapy.ResultsThe median age of a total of 276 patients was 57.5 years (range 18-83), and majority of them (55.8%) were women. Among the pre-chemotherapy factors that could be associated with sarcopenia, male gender >= 65 years of age, body mass ndex (BMI) < 25, and nutritional risk screening 2002 score < 3 were found to be positively associated with sarcopenia (p < 0.001, p = 0.036, p < 0.001, and p < 0.001, respectively). In the multivariate analysis, male gender (p < 0.001) and BMI < 25 (p = 0.047) were found to be significant. Of 276 patients, 14.5% were sarcopenic prior to chemotherapy. After chemotherapy, 21.4% of them were sarcopenic at the end of the third month and 23.9% were sarcopenic at the end of the sixth month.ConclusionThe incidence of sarcopenia was found to be increased with chemotherapy itself and its duration in both non-metastatic and metastatic cancer patients which has to be evaluated in detail in disease-specific prospective and randomized studies.
