It is well established that breast cancer development and progression depend not only on tumor-cell intrinsic factors but also on its microenvironment and on the host characteristics. There is growing evidence that adipocytes play a role in breast cancer progression. This is supported by: (i) epidemiological studies reporting the association of obesity with a higher cancer risk and poor prognosis, (ii) recent studies demonstrating the existence of a cross-talk between breast cancer cells and adipocytes locally in the breast that leads to acquisition of an aggressive tumor phenotype, and (iii) evidence showing that cancer cachexia applies also to fat tissue and shares similarities with stromal-carcinoma metabolic synergy. This review summarizes the current knowledge on the epidemiological link between obesity and breast cancer and outlines the results of the tumor-adipocyte crosstalk. We also focus on systemic changes in body fat in patients with cachexia developed in the course of cancer. Moreover, we discuss and compare adipocyte alterations in the three pathological conditions and the mechanisms through which breast cancer progression is induced.

The main goal of traditional treatment of idiopathic retroperitoneal fibrosis is limitation of morbidity, and surgery of already formed fibrous masses has been the main therapeutic approach. More recently, the knowledge that the disorder may be the result of an allergic reaction to atherosclerotic lipids has prompted the use of corticosteroids and cytotoxic drugs, which proved eYcacious, but also toxic. On the basis of data indicating a T cell pathogenesis of idiopathic retroperitoneal fibrosis, cyclosporin, a non-cytotoxic pretranscriptional inhibitor of proinflammatory cytokines, was used to treat the case reported here. A 65 year old man with aggressive retroperitoneal fibrosis and obstructive renal failure initially received steroids, which eventually lost their eYcacy and led to vertebral collapse. He responded to 5 mg/kg/day cyclosporin, with radiological reduction of tissue deposition, relief of urether compression, and reduction in acute phase reactants in the blood. Chronic disease remission required stable drug concentrations. In conclusion, progress in research into the T cell pathogenesis of idiopathic retroperitoneal fibrosis may justify attempts with drugs such as cyclosporin to block the disease at its origin rather than treating the morbidity.

This study aimed to evaluate the work ability and its associated factors in patients with glioma (II, III) and breast cancer after 6 (T0) and 12 (T1) months from surgery. A total of 99 patients were evaluated with self-reported questionnaires at T0 and T1. Correlation and Mann–Whitney tests were used to investigate the association between work ability and sociodemographic, clinical, and psychosocial factors. The Wilcoxon test was used to investigate the longitudinal change in work ability. Our sample showed a decrease in work ability level between T0 and T1. Work ability was associated with emotional distress, disability, resilience, and social support in glioma III patients at T0, and with fatigue, disability, and clinical treatments in patients with breast cancer at T0 and T1. Work ability levels decreased in patients with glioma and breast cancer and were associated with different psychosocial factors after surgery. Their investigation is suggested to facilitate the return to work.
