BackgroundEnergy homeostasis is mediated by the hypothalamus, whose inflammation‐induced functional derangements contribute to the onset of anorexia in cancer. By using functional magnetic resonance imaging (fMRI), we determined the patterns of hypothalamic activation after oral intake in anorexic (A), non‐anorexic (NA) cancer patients, and in controls (C).MethodsLung cancer patients were considered. Hypothalamic activation was recorded in A and NA patients and in C by fMRI, before (T0), immediately after (T1) the administration of an oral nutritional supplement, and after 15 min (T2). The grey of the hypothalamus and Blood Oxygen Level Dependent (BOLD) intensity were calculated and normalized for basal conditions. Interleukin (IL)‐1, IL‐6, tumour necrosis factor (TNF)‐α, ghrelin, and leptin plasma levels were measured. A statistical parametric mapping was used.ResultsThirteen lung cancer patients (7 M, 6 F; 9A, 4NA) and 2 C (1 M, 1 F) were enrolled. Controls had the lowest BOLD intensity. At all‐time points, anorexic patients showed lower hypothalamic activity compared with NA (P < 0.001) (T0: 585.57 ± 55.69 vs. 667.92 ± 33.18, respectively; T1: 536.50 ± 61.70 vs. 624.49 ± 55.51, respectively; T2: 556.44 ± 58.51 vs. 615.43 ± 71.50, respectively). Anorexic patients showed greater BOLD signal reduction during T0–T1 than NA (−8.5% vs. −6.80%, P < 0.001). Independently from the presence of anorexia, BOLD signals modification before and after oral challenge correlated with basal values of IL‐1 and ghrelin (P < 0.001).ConclusionsHypothalamic activity in A cancer patients is reduced respect to NA and responds differently to oral challenges. This suggests a central control of appetite dysregulation during cancer anorexia, before, and after oral intake.

Patients with cancer frequently use dietary supplementation and herbal therapies to control symptoms of disease and adverse effects of cancer therapy. Despite the widespread use of dietary supplementation and herbal therapies in oncology, robust scientific evidence in this area is lacking. Not only do these products need to be tested in large and well-designed observational or randomized studies, but their manufacturing process must be improved to achieve higher levels of standardization in product quality. Ginger is frequently used to counteract chemotherapy-induced nausea and vomiting (CINV), and some suggestions that it might be effective against CINV come from randomized and/or crossover clinical trials. However, several limitations in the methods of these studies limit their power and generalizability. The authors are conducting a randomized, double-blind study with a large sample size and homogeneous inclusion criteria in order to evaluate the efficacy of a wellstandardized ginger extract in reducing nausea in patients with cancer. The widespread use of standardized herbal therapies and natural components among patients requires that scientific and rigorous research strategies are applied in this field to guide the physicians and the patients in safer use.

BackgroundConsolidation with or without ground-glass opacity is the typical radiologic finding of lung metastases of adenocarcinoma from the gastrointestinal tract. Lung excavated metastases from gastrointestinal carcinoma are very rare.Case presentationThe authors describe an unusual presentation of multiple cavitated lung metastases from colon adenocarcinoma and discuss the outcome of a patient. The absence both of symptoms and other disease localizations, the investigations related to different diagnostic hypotheses and the empirical treatments caused a delay in correct diagnosis. Only a transparietal biopsy revealed the neoplastic origin of nodules.ConclusionsThis report demonstrates that although lung excavated metastases are described in literature, initial failure to reach a diagnosis is common. We would like to alert clinicians and radiologists to the possibility of unusual atypical features of pulmonary metastases from colon adenocarcinoma.
