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., (© 2020 The Authors.

Purpose: Chemotherapy-induced hair loss is a common and distressing side effect. Scalp cooling is increasingly being used to reduce this hair loss. The purpose of this study was to explore patients' perceptions and experience of scalp cooling., Methods: Seventeen Australian women with a diagnosis of breast cancer participated in a focus group (n = 4) or a semi-structured interview (n = 3). Both scalp-cooled and non-scalp-cooled participant views were sought. Participant perceptions and experiences of scalp cooling were discussed as part of patients' overall chemotherapy experience and a thematic analysis conducted., Results: Five themes emerged from the data: (1) scalp cooling in the context of treatment decision-making discussions, (2) hair loss expectations vs. experiences, (3) treatment-related expectations vs. experiences, (4) the promise of faster regrowth and (5) satisfaction with scalp cooling and future scalp cooling decision-making considerations. Information during treatment decision-making was the primary factor that influenced whether patient expectations were met. Faster regrowth was a motivator to continue treatment. Efficacy and tolerability of scalp cooling influenced future hypothetical treatment decision-making for both scalp-cooled and non-scalp-cooled participants., Conclusions: This study provides the first in-depth exploration of patient attitudes to scalp cooling. The results highlight a need for accurate information regarding efficacy and tolerability as well as hair care information to assist patients with their treatment decision-making.

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., (© 2016 John Wiley & Sons Australia, Ltd.)

Gene expression profiling has reshaped our understanding of breast cancer by defining and characterizing four main intrinsic molecular subtypes: human epidermal growth factor receptor 2-enriched, basal-like, luminal A, and luminal B subtypes. Luminal B breast cancer has been reported to have lower expression of hormone receptors, higher expression of proliferation markers, and higher histologic grade than luminal A. It also exhibits worse prognosis and has a distinct profile of response to hormone therapy and chemotherapy. Although luminal cancers share similarities, the studies conducted in recent years using next-generation sequencing technology show that luminal A and B breast cancers should be perceived as distinct entities, with specific oncogenic drivers, rather than more proliferative varieties of luminal tumors. This review discusses the definition and molecular characterization of luminal B breast cancer and presents the available clinical evidence for chemotherapy and endocrine therapy patterns of response. It also provides an overview of ongoing research on molecularly targeted agents for this disease., (© 2014 by American Society of Clinical Oncology.)

To support the efficient execution of post-genomic multi-centric clinical trials in breast cancer we propose a solution that streamlines the assessment of the eligibility of patients for available trials. The assessment of the eligibility of a patient for a trial requires evaluating whether each eligibility criterion is satisfied and is often a time consuming and manual task. The main focus in the literature has been on proposing different methods for modelling and formalizing the eligibility criteria. However the current adoption of these approaches in clinical care is limited. Less effort has been dedicated to the automatic matching of criteria to the patient data managed in clinical care. We address both aspects and propose a scalable, efficient and pragmatic patient screening solution enabling automatic evaluation of eligibility of patients for a relevant set of trials. This covers the flexible formalization of criteria and of other relevant trial metadata and the efficient management of these representations.

Breast cancer oncology represents one of the disciplines where personalized cancer medicine has been most actively pursued. The class-discovery studies conceptually advanced the field, underlining the molecular heterogeneity governing this common disease. The advent of high-throughput molecular profiling technologies holds great promise for the advance of all aspects of personalized cancer medicine, namely accurate prognostication, prediction of response to common systemic therapies and individualized monitoring of the disease. Moreover, an ever-expanding arsenal of targeted therapeutic compounds under clinical development, coupled with emerging powerful tools for comprehensive molecular and functional characterization, pose significant promise for improved clinical outcomes for breast cancer patients. Interrogation of the germline genetic variation offers further promise towards tailoring of breast cancer management. Well-conducted prospective validation studies are needed if breast cancer personalized therapy is to transform from a dream into a reality.

Purpose of Review: There have been recent new developments in the treatment of breast cancer that over-expresses HER2 (ERRB2/HER2 positive) and the mechanistic understanding of trastuzumab response. We review these findings and reflect on how they may influence the next generation of clinical trials in this breast cancer subtype., Recent Findings: Two recent trials in the neoadjuvant setting report that treatment with dual anti-HER2 agents was superior, in terms of rates of pathological complete response, to trastuzumab alone. Recent data also highlight that HER2 positive disease is biologically different according to estrogen receptor status and for long lasting clinical remissions, anti-HER2 therapy also seems to require an effective adaptive immune response., Summary: We are currently in a very exciting era for therapeutic approaches in HER2 positive disease. Recent data suggest that intensive chemotherapy regimens may not be required for some women if we can determine the most potent combinations of signal inhibitors. We also propose that different clinical trials may need to be designed for HER2 positive breast cancer according to estrogen receptor status and consider incorporating immunotherapeutic approaches.
