The high prevalence of anxiety and depression among Spaniards with cancer starting adjuvant chemotherapy suggests that more attention should be paid to mental health in these individuals. These findings are important for cancer patients because they can benefit from interventions that increase positive psychological factors such as hope, optimism, and social support to reduce anxiety and depression.

Purpose: The limited knowledge of the molecular alterations that characterize poorly differentiated neuroendocrine carcinomas has limited the clinical development of targeted agents directed to driver mutations. Here we aim to identify new molecular targets in colon neuroendocrine carcinomas (co-NEC) and proof the efficacy of matching drugs. Experimental Design: We performed a multi-omic analysis of co-NEC to identify genetic or epigenetic alterations that could be exploited as effective drug targets. We compared co-NEC samples with colorectal carcinomas (CRC) to identify neuroendocrinespecific traits. Patients with co-NEC and patient-derived xenografts were treated with a BRAFV600E-blocking drug to demonstrate sensitivity. Results: co-NEC and CRC are similar in their mutational repertoire, although co-NECs are particularly enriched in BRAFV600E mutations. We report for the first time that V600EBRAF-mutant co-NECs may benefit from BRAF inhibition in monotherapy and how EGFR status is essential to predict innate sensitivity and acquired resistance by a differential methylation of its gene regulatory regions. Conclusions: The identification of V600E BRAF mutations in high-grade co-NECs has allowed the description of radiological responses to combination therapy of BRAF and MEK inhibitors in basket clinical trials. However, the molecular rationale for this treatment combination was based on the presence of the BRAF mutation and the efficacy observed in other cancer types such as melanoma. Future drug development in this setting should test BRAF inhibitors upfront and the addition of anti-EGFR antibodies instead of MEK inhibitors for an efficient blockade of acquired resistance.

Objective Cancer patients are at increased risk for psychological difficulties and COVID-19. We sought to analyze anxiety and depression levels during the COVID-19 pandemic and the association between sociodemographic, clinical, and psychological factors in patients with advanced cancer. Methods A prospective, multicenter cohort of 401 consecutive patients with newly diagnosed, advanced cancer completed the Brief Symptom Inventory, Michel Uncertainty in Illness Scale, Herth Hope Index, and Cancer Worry Scale between February 2020 and May 2021. Linear regression analyses explored the effects of uncertainty, hopelessness, and cancer worry on anxiety and depression, adjusting for sociodemographic and clinical variables. ResultsThe incidence of anxiety and depression was 36% and 35%, respectively. Emotional distress was greater among women, patients < 65 years of age, and those with an estimated survival of > 18 months. Linear regression analysis revealed that being female, preoccupation about cancer, and hopelessness were associated with increased levels of anxiety (p < 0.001) and depression (p < 0.001) and younger age was associated with a higher risk of anxiety. No differences in anxiety or depression levels were found in relation to marital status, children, educational level, cancer type, histology, stage, or type of treatment. Conclusions Patients with advanced cancer who initiated treatment during the pandemic experienced high levels of depression and anxiety. Early diagnosis and the development of intervention strategies are necessary, especially for specific patient subgroups, such as young women with long survival times.

Background/objectiveThe impact a cancer diagnosis and its treatment are affected by psychosocial factors and how these factors interrelate among themselves. The objective of this study was to analyze the relationship between optimism and social support in spiritual wellbeing in cancer patients initiating chemotherapy. MethodsA cross-sectional, multi-center (15 sites), prospective study was conducted with 912 cancer patients who had undergone curative surgery for a stage I-III cancer and were to receive adjuvant chemotherapy. They completed the Functional Assessment of Chronic Illness-Spiritual Well-being Scale (FACIT-Sp), Life Orientation Test-Revised (LOT-R), and the Multidimensional Scale of Perceived Social Support (MSPSS).
