This position statement describes the recommendations of the Clinical Oncology Society of Australia (COSA) regarding management of cancer‐related malnutrition and sarcopenia. A multidisciplinary working group completed a review of the literature, focused on evidence‐based guidelines, systematic reviews and meta‐analyses, to develop recommendations for the position statement. National consultation of the position statement content was undertaken through COSA members. All people with cancer should be screened for malnutrition and sarcopenia in all health settings at diagnosis and as the clinical situation changes throughout treatment and recovery. People identified as "at risk" of malnutrition or with a high‐risk cancer diagnosis or treatment plan should have a comprehensive nutrition assessment; people identified as "at risk" of sarcopenia should have a comprehensive evaluation of muscle status using a combination of assessments for muscle mass, muscle strength and function. All people with cancer‐related malnutrition and sarcopenia should have access to the core components of treatment, including medical nutrition therapy, targeted exercise prescription and physical and psychological symptom management. Treatment for cancer‐related malnutrition and sarcopenia should be individualised, in collaboration with the multidisciplinary team (MDT), and tailored to meet needs at each stage of cancer treatment. Health services should ensure a broad range of health care professionals across the MDT have the skills and confidence to recognise malnutrition and sarcopenia to facilitate timely referrals and treatment. The position statement is expected to provide guidance at a national level to improve the multidisciplinary management of cancer‐related malnutrition and sarcopenia. [ABSTRACT FROM AUTHOR]

Aim Treatment with pertuzumab-trastuzumab-taxane combinations has become the international standard of care for patients with HER2-positive metastatic breast cancer. In this paper we discuss the practicalities of treating patients with this combination with a particular focus on treatment in the Australian setting. Method An expert panel was convened to discuss practical aspects for use of pertuzumab in the Australian clinical setting. The findings of this panel are reported in this article. Results The combination of pertuzumab-trastuzumab-docetaxel has established efficacy in patients with HER2-positive metastatic breast cancer, prolonging progression-free and overall survival compared to trastuzumab-taxane combinations. In Australia, combinations of pertuzumab and trastuzumab with docetaxel or paclitaxel are reimbursed. Management of treatment related side-effects such as diarrhea, febrile neutropenia and neuropathy typically include dose reduction or switching taxane. Specific patients with poorer tolerance of chemotherapy such as the elderly or those from Asian backgrounds may require particular management strategies. Conclusions The advent of targeted therapies for women with metastatic HER2-positive breast cancer has markedly improved survival. Combinations of pertuzumab-trastuzumab and a taxane are the standard of care in patients with good performance status. Given prolongation of survival and the importance of quality of life endpoints, the treatment paradigm for patients with metastatic HER2-positive breast cancer is changing rapidly. Careful management of toxicities is required, and dose reduction or switching taxane may be necessary. Further research is required on the efficacy of pertuzumab combinations in patients with brain metastases, and on those who relapse quickly following adjuvant therapy. [ABSTRACT FROM AUTHOR]
