Summary To develop a framework for the definition and classification of cancer cachexia a panel of experts participated in a formal consensus process, including focus groups and two Delphi rounds. ...Cancer cachexia was defined as a multifactorial syndrome defined by an ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support and leads to progressive functional impairment. Its pathophysiology is characterised by a negative protein and energy balance driven by a variable combination of reduced food intake and abnormal metabolism. The agreed diagnostic criterion for cachexia was weight loss greater than 5%, or weight loss greater than 2% in individuals already showing depletion according to current bodyweight and height (body-mass index BMI <20 kg/m2 ) or skeletal muscle mass (sarcopenia). An agreement was made that the cachexia syndrome can develop progressively through various stages—precachexia to cachexia to refractory cachexia. Severity can be classified according to degree of depletion of energy stores and body protein (BMI) in combination with degree of ongoing weight loss. Assessment for classification and clinical management should include the following domains: anorexia or reduced food intake, catabolic drive, muscle mass and strength, functional and psychosocial impairment. Consensus exists on a framework for the definition and classification of cancer cachexia. After validation, this should aid clinical trial design, development of practice guidelines, and, eventually, routine clinical management.
Opinion statement
Loss of appetite is common among patients with advanced cancer. However, it remains controversial how, when, and if to palliate this symptom. Here, we provide an update on recent as ...well as past literature to address the question of whether loss of appetite should be palliated in patients with advanced cancer. In our opinion—and as discussed here—we believe that this symptom should be palliated, although perhaps not always with pharmacologic interventions.
Lung cancer is a disease of the elderly. In older patients, the management of a malignancy as complex and potentially as lethal as lung cancer is challenging. Despite the fact that a large proportion ...of patients with non–small-cell lung cancer are elderly, information remains scant on how best to treat these patients. The goal of this review is to discuss the published literature and to provide guidance on how to treat elderly patients within three broad stages: (1) metastatic cancer, (2) early-stage cancer after surgery, and (3) locally advanced inoperable cancer. Because decisions on how and when to prescribe systemic treatment can be particularly difficult, this review focuses heavily on chemotherapy-related treatment decisions with some discussion of emerging data on the use of the comprehensive geriatric assessment.
Cancer is a disease of aging and, as the world's population ages, the number of older persons with cancer is increasing and will make up a growing share of the oncology population in virtually every ...country. Despite this, older patients remain vastly underrepresented in research that sets the standards for cancer treatments. Consequently, most of what we know about cancer therapeutics is based on clinical trials conducted in younger, healthier patients, and effective strategies to improve clinical trial participation of older adults with cancer remain sparse. For this systematic review, the authors evaluated published studies regarding barriers to participation and interventions to improve participation of older adults in cancer trials. The quality of the available evidence was low and, despite a literature describing multifaceted barriers, only one intervention study aimed to increase enrollment of older adults in trials. The findings starkly amplify the paucity of evidence‐based, effective strategies to improve participation of this underrepresented population in cancer trials. Within these limitations, the authors provide their opinion on how the current cancer research infrastructure must be modified to accommodate the needs of older patients. Several underused solutions are offered to expand clinical trials to include older adults with cancer. However, as currently constructed, these recommendations alone will not solve the evidence gap in geriatric oncology, and efforts are needed to meet older and frail adults where they are by expanding clinical trials designed specifically for this population and leveraging real‐world data.
Chemotherapy-induced hiccups are understudied but can cause sleep deprivation, fatigue, pain in the chest and abdomen, poor oral intake, aspiration, and even death. As a critical next step toward ...investigating better palliative methods, this study reported patient-reported incidence of hiccups after oxaliplatin- or cisplatin-based chemotherapy.
The current study relied on 2 previous studies that sought to acquire consecutive direct patient report of hiccups among patients who had recently received chemotherapy with cisplatin or oxaliplatin. These patient-reported data in conjunction with information from the medical record are the focus of this report.
Of 541 patients, 337 were successful contacted by phone; and 95 (28%; 95% CI: 23%, 33%) of these contacted patients reported hiccups. In univariable analyses, male gender (odds ratio (OR): 2.17 (95% confidence ratio (95% CI): 1.30, 3.62); p = 0.002), increased height (OR: 1.03 (95% CI: 1.00, 1.06); p = 0.02), and concomitant aprepitant/fosaprepitant (OR: 2.23 (95% CI: 1.31, 3.78); p = 0.002) were associated with hiccups. In multivariable analyses, these statistically significant associations persisted except for height.
These patient-reported data demonstrate that oxaliplatin- or cisplatin-induced hiccups occur in a notable proportion of patients with cancer. Male gender and concomitant aprepitant/fosaprepitant appear to increase risk.

The term sarcopenia was introduced in 1988. The original definition was a “muscle loss” of the appendicular muscle mass in the older people as measured by dual energy x‐ray absorptiometry (DXA). In ...2010, the definition was altered to be low muscle mass together with low muscle function and this was agreed upon as reported in a number of consensus papers. The Society of Sarcopenia, Cachexia and Wasting Disorders supports the recommendations of more recent consensus conferences, i.e. that rapid screening, such as with the SARC‐F questionnaire, should be utilized with a formal diagnosis being made by measuring grip strength or chair stand together with DXA estimation of appendicular muscle mass (indexed for height2). Assessments of the utility of ultrasound and creatine dilution techniques are ongoing. Use of ultrasound may not be easily reproducible. Primary sarcopenia is aging associated (mediated) loss of muscle mass. Secondary sarcopenia (or disease‐related sarcopenia) has predominantly focused on loss of muscle mass without the emphasis on muscle function. Diseases that can cause muscle wasting (i.e. secondary sarcopenia) include malignant cancer, COPD, heart failure, and renal failure and others. Management of sarcopenia should consist of resistance exercise in combination with a protein intake of 1 to 1.5 g/kg/day. There is insufficient evidence that vitamin D and anabolic steroids are beneficial. These recommendations apply to both primary (age‐related) sarcopenia and secondary (disease related) sarcopenia. Secondary sarcopenia also needs appropriate treatment of the underlying disease. It is important that primary care health professionals become aware of and make the diagnosis of age‐related and disease‐related sarcopenia. It is important to address the risk factors for sarcopenia, particularly low physical activity and sedentary behavior in the general population, using a life‐long approach. There is a need for more clinical research into the appropriate measurement for muscle mass and the management of sarcopenia. Accordingly, this position statement provides recommendations on the management of sarcopenia and how to progress the knowledge and recognition of sarcopenia.
Immune checkpoint inhibitors are a new class of cancer drug that spawn unusual adverse events that generate unusual and sometimes unexpected adverse events. Despite databases that track such adverse ...events, there remains a need to also generate systematic reviews to capture side effects from such agents.
We generated a systematic compendium of adverse event reports. Extensively reviewing the published literature of case reports and case series, we relied on the peer process to compile a resource for clinicians of rare adverse events associated with checkpoint inhibitors. We used this compendium as a platform to provide broad-based comments on the role of systematic reviews in gathering such adverse event data. This approach generated 265 types of rare adverse events that had been reported, the most frequent of which were autoimmune type I diabetes (n = 62), pneumonitis (n = 40), myocarditis (n = 39), and colitis (n = 36). More unusual adverse events were also catalogued. Some adverse events that initially seemed unusual turned out to be more frequently reported over time and thus lost their novelty-an important point which provides context for how adverse events should be viewed when new drugs become available. Additionally, in contrast to such resources as the FDA Adverse Event Reporting System (FAERS), this systematic review relied on peer-reviewed data-another important point which adds strength to such systematic reviews. This report provides a compendium of rare and usual adverse events, serves as a resource to cancer clinicians, and appears to be justified based on the reported findings.
Purpose
This qualitative study sought to learn patients’ perspectives on olaparib — including maintenance olaparib — in their own words.
Methods
Olaparib-treated patients were interviewed by phone. A ...semi-structured interview guide that focused on symptoms and quality of life was formulated in alignment with the study objective. Interviews were transcribed and analyzed with content analysis.
Results
Twenty olaparib-treated patients were interviewed. Four themes emerged: (1) The Long Cancer Journey. Patients prescribed olaparib appear to have had a long cancer journey, sometimes with prior cancer (“I had breast cancer in 1996”) and sometimes with a long interval from an ovarian cancer diagnosis; (2) Adherence. Despite this journey, patients were adherent to olaparib (“I set it for an alarm 15 min before I have to take olaparib and then exactly when I’m supposed to take it”); (3) Adherence Despite Challenges. Adherence continued despite side effects (although olaparib was “pretty tolerable”). This adherence also continued despite cost (“…for a month’s supply, mine was $15,837… and my insurance covered some of it but not near enough”), and (4) Modifications in Perceptions of BRCA Status. Olaparib as cancer therapy influenced perceptions of BRCA mutations (“But I… I have to tell you, I’m grateful that I qualified to be on Lynparza®”).
Conclusion
Although oral maintenance therapy for ovarian cancer is relatively new, patients appear willing to take olaparib long term; and they seem to take great lengths to remain adherent, despite having sometimes had a long cancer journey.
Cancer cachexia is a complex metabolic condition characterized by loss of skeletal muscle. Common clinical manifestations include muscle wasting, anemia, reduced caloric intake, and altered immune ...function, which contribute to increased disability, fatigue, diminished quality of life, and reduced survival. The prevalence of cachexia and the impact of this disorder on the patient and family underscore the need for effective management strategies. Dietary supplementation and appetite stimulation alone are inadequate to reverse the underlying metabolic abnormalities of cancer cachexia and have limited long-term impact on patient quality of life and survival. Therapies that can increase muscle mass and physical performance may be a promising option; however, there are currently no drugs approved for the prevention or treatment of cancer cachexia. Several agents are in clinical development, including anabolic agents, such as selective androgen receptor modulators and drugs targeting inflammatory cytokines that promote skeletal muscle catabolism.
