SUMMARY
Sarcopenia is defined as the loss of muscle mass and strength and plays an increasingly important role in the management of oncology patients. Sarcopenia is frequently mislabelled as malnutrition or cachexia. Clinicians lack a consensus definition of easy-to-use, straightforward, reliable diagnostic tools to optimally recognise sarcopenia. This review will broadly go through the current literature in order to define sarcopenia, as well as to understand its mechanisms. Helpful diagnostic tools will be discussed, which can be used to optimise the management of patients suffering from a malignant disease. This review will also illustrate how sarcopenia is an independent negative predictive and prognostic factor regarding survival and quality of life, directly impacting toxicity and efficacy of oncological treatments.

Summary
Patients with HER2-positive advanced breast cancer frequently develop brain metastases. Dual anti-HER2 therapy significantly prolongs survival in previously untreated metastatic disease. However, no safety data exist on the concurrent use of pertuzumab, trastuzumab and brain radiotherapy. We describe two cases of previously untreated HER2-positive breast cancer and brain metastases, who developed acute cerebral toxicity during the concomitant administration of anti-HER2 therapy and whole-brain radiotherapy. Systematic clinical data is warranted to prove the safety of this association.
