What do patients and oncologists think about the evaluation and management of cancer-related anorexia-cachexia? The Quasar_SEOM study.

INTRODUCTION: Cancer patients often suffer from malnutrition and early detection and raising awareness of nutritional issues is crucial in this population. METHODS: The Spanish Oncology Society (SEOM) conducted the Quasar_SEOM study to investigate the current impact of the Anorexia-Cachexia Syndrome (ACS). The study employed questionnaires and the Delphi method to gather input from both cancer patients and oncologists on key issues related to early detection and treatment of ACS. A total of 134 patients and 34 medical oncologists were surveyed about their experiences with ACS. The Delphi methodology was used to evaluate oncologists' perspectives of ACS management, ultimately leading to a consensus on the most critical issues. RESULTS: Despite widespread acknowledgement of malnutrition in cancer as a significant issue by 94% of oncologists, the study revealed deficiencies in knowledge and protocol implementation. A mere 65% of physicians reported being trained to identify and treat these patients, with 53% failing to address ACS in a timely manner, 30% not monitoring weight, and 59% not adhering to any clinical guidelines. The lack of experience was identified as the primary hindrance to the use of orexigens in 18% of cases. Furthermore, patients reported concerns and a perception of inadequate attention to malnutrition-related issues from their physicians. CONCLUSION: The results of this study point to a gap in the care of this syndrome and a need to improve education and follow-up of cancer patients with anorexia-cachexia.

Can Oncologists Prompt Patient Prognostic Awareness to Enhance Decision-Making? Data From the NEOetic Study.

INTRODUCTION: Anti-neoplastic therapy improves the prognosis for advanced cancer, albeit it is not curative. An ethical dilemma that often arises during patients' first appointment with the oncologist is to give them only the prognostic information they can tolerate, even at the cost of compromising preference-based decision-making, versus giving them full information to force prompt prognostic awareness, at the risk of causing psychological harm. METHODS: We recruited 550 participants with advanced cancer. After the appointment, patients and clinicians completed several questionnaires about preferences, expectations, prognostic awareness, hope, psychological symptoms, and other treatment-related aspects. The aim was to characterize the prevalence, explanatory factors, and consequences of inaccurate prognostic awareness and interest in therapy. RESULTS: Inaccurate prognostic awareness affected 74%, conditioned by the administration of vague information without alluding to death (odds ratio [OR] 2.54; 95% CI, 1.47-4.37, adjusted P = .006). A full 68% agreed to low-efficacy therapies. Ethical and psychological factors oriented first-line decision-making, in a trade-off in which some lose quality of life and mood, for others to gain autonomy. Imprecise prognostic awareness was associated with greater interest in low-efficacy treatments (OR 2.27; 95% CI, 1.31-3.84; adjusted P = .017), whereas realistic understanding increased anxiety (OR 1.63; 95% CI, 1.01-2.65; adjusted P = 0.038), depression (OR 1.96; 95% CI, 1.23-3.11; adjusted P = .020), and diminished quality of life (OR 0.47; 95% CI, 0.29-0.75; adjusted P = .011). CONCLUSION: In the age of immunotherapy and targeted therapies, many appear not to understand that antineoplastic therapy is not curative. Within the mix of inputs that comprise inaccurate prognostic awareness, many psychosocial factors are as relevant as the physicians' disclosure of information. Thus, the desire for better decision-making can actually harm the patient.

Shared Oncogenic Pathways Implicated in Both Virus-Positive and UV-Induced Merkel Cell Carcinomas.

Merkel cell carcinoma (MCC) is a highly malignant neuroendocrine tumor of the skin whose molecular pathogenesis is not completely understood, despite the role that Merkel cell polyomavirus can play in 55-90% of cases. To study potential mechanisms driving this disease in clinically characterized cases, we searched for somatic mutations using whole-exome sequencing, and extrapolated our findings to study functional biomarkers reporting on the activity of the mutated pathways. Confirming previous results, Merkel cell polyomavirus-negative tumors had higher mutational loads with UV signatures and more frequent mutations in TP53 and RB compared with their Merkel cell polyomavirus-positive counterparts. Despite important genetic differences, the two Merkel cell carcinoma etiologies both exhibited nuclear accumulation of oncogenic transcription factors such as NFAT or nuclear factor of activated T cells (NFAT), P-CREB, and P-STAT3, indicating commonly deregulated pathogenic mechanisms with the potential to serve as targets for therapy. A multivariable analysis identified phosphorylated CRE-binding protein as an independent survival factor with respect to clinical variables and Merkel cell polyomavirus status in our cohort of Merkel cell carcinoma patients.
