Impact of Obesity on Quality of Life, Psychological Distress, and Coping on Patients with Colon Cancer.

BACKGROUND: Despite the causal relationship between obesity and colon cancer being firmly established, the effect of obesity on the course of cancer calls for further elucidation. The objective of this study was to assess differences in clinical-pathological and psychosocial variables between obese and nonobese individuals with colon cancer. MATERIALS AND METHODS: This was a prospective, multicentric, observational study conducted from 2015-2018. The sample comprised patients with stage II-III, resected colon cancer about to initiate adjuvant chemotherapy with fluoropyrimidine in monotherapy or associated with oxaliplatin and grouped into nonobese (body mass index <30 kg/m2 ) or obese (≥30 kg/m2 ). Subjects completed questionnaires appraising quality of life (European Organization for Research and Treatment of Cancer Quality of Life Core questionnaire), coping (Mini-Mental Adjustment to Cancer), psychological distress (Brief Symptom Inventory 18), perceived social support (Multidimensional Scale of Perceived Social Support), personality (Big Five Inventory 10), and pain (Brief Pain Inventory). Toxicity, chemotherapy compliance, 12-month recurrence, and mortality rate data were recorded. RESULTS: Seventy-nine of the 402 individuals recruited (19.7%) were obese. Obese subjects exhibited more comorbidities (≥2 comorbidities, 46.8% vs. 30.3%, p = .001) and expressed feeling slightly more postoperative pain (small size-effect). There was more depression, greater helplessness, less perceived social support from friends, and greater extraversion among the obese versus nonobese subjects (all p < .04). The nonobese group treated with fluoropyrimidine and oxaliplatin suffered more grade 3-4 hematological toxicity (p = .035), whereas the obese had higher rates of treatment withdrawal (17.7% vs. 7.7%, p = .033) and more recurrences (10.1% vs. 3.7%, p = .025). No differences in sociodemographic, quality of life, or 12-month survival variables were detected. CONCLUSION: Obesity appears to affect how people confront cancer, as well as their tolerance to oncological treatment and relapse. IMPLICATIONS FOR PRACTICE: Obesity is a causal factor and affects prognosis in colorectal cancer. Obese patients displayed more comorbidities, more pain after cancer surgery, worse coping, and more depression and perceived less social support than nonobese patients. Severe hematological toxicity was more frequent among nonobese patients, whereas rates of withdrawal from adjuvant chemotherapy were higher in the obese cohort, and during follow-up, obese patients presented greater 12-month recurrence rates. With the growing and maintained increase of obesity and the cancers associated with it, including colorectal cancer, the approach to these more fragile cases that have a worse prognosis must be adapted to improve outcomes.

Safety and efficacy of sorafenib in the treatment of advanced hepatocellular carcinoma: a single center experience.

Sorafenib is the standard treatment of patients with advanced hepatocellular carcinoma (HCC), with demonstrated outcome benefits in randomized clinical trials. We present a single-center experience with sorafenib with the aim to establish its efficacy and safety in daily clinical practice. A total of 62 patients were treated with sorafenib 400 mg/12 h until disease progression or unacceptable toxicity. Response rates, incidence of adverse events, actuarial disease-free survival, and overall survival (OS) were estimated. Univariate and multivariate analyses of prognostic factors for survival were also performed. Median treatment duration was 92 days. A 43% disease control rate was achieved (partial response, 15% and disease stabilization, 28%). After a median follow-up of 24.1 months, the median progression-free survival and OS for the overall population were 5.8 and 6.7 months, respectively, with survival rates of 27% at 1 year and 17 % at 2 years. The most common grade 3-4 adverse events were fatigue (19%), hand-foot syndrome (8%), hypertension (5%), and diarrhea (3%). The univariate analysis showed that patient performance status (PS), use of previous treatments, and albumin >3.5 g/dL were significant prognostic factors for survival. In the multivariate study, only PS, alcoholic etiology and albumin >3.5 g/dL remained as independent predictors of survival. Sorafenib is a safe and moderately effective drug in HCC, although patients must be properly selected before starting therapy. Baseline PS, Barcelona Clinic Liver Cancer staging, and liver function should be taken into account as prognostic factors. Results in daily practice are somewhat inferior than observed in clinical trials.

Molecular pathology and prostate cancer therapeutics: from biology to bedside.

Prostate cancer (PCa) is the second most commonly diagnosed malignancy in men and has an extremely heterogeneous clinical behaviour. The vast majority of PCas are hormonally driven diseases in which androgen signalling plays a central role. The realization that castration-resistant prostate cancer (CRPC) continues to rely on androgen signalling prompted the development of new, effective androgen blocking agents. As the understanding of the molecular biology of PCas evolves, it is hoped that stratification of prostate tumours into distinct molecular entities, each with its own set of vulnerabilities, will be a feasible goal. Around half of PCas harbour rearrangements involving a member of the ETS transcription factor family. Tumours without this rearrangement include SPOP mutant as well as SPINK1-over-expressing subtypes. As the number of targeted therapy agents increases, it is crucial to determine which patients will benefit from these interventions and molecular pathology will be key in this respect. In addition to directly targeting cells, therapies that modify the tumour microenvironment have also been successful in prolonging the lives of PCa patients. Understanding the molecular aspects of PCa therapeutics will allow pathologists to provide core recommendations for patient management.
