Risk factors for this malignant disease include cigarette smoking, family history of chronic pancreatitis, advancing age, male sex, diabetes mellitus, obesity, non-0 blood group, a high-fat diet, alcohol consumption and possibly Helicobacter pylori and hepatitis B virus infections. Metabolic diseases have become the leading cause of death in many countries. Our paper serves as a focused and updated discussion about the development of novel preventive strategies for this deadly disease.

Data from several epidemiologic studies have allowed us to exclude a strong association between alcohol drinking and prostate cancer risk. However, limited information is available for BPH. Also, it is unclear whether various types of alcoholic beverages may have a different impact on risk. We conducted this hospital-based case-control study in Italy between 1991 and 2002. A total of 2663 men younger than 75 years had incident, histologically confirmed prostate carcinoma (1294 cases) or symptomatic obstructive BPH (1369 cases) (maximal flow rate less than 15 mL/s) refractory to medical treatment. A total of 1451 patients younger than 75 years were used as controls. Odds ratios and corresponding 95% confidence intervals were estimated using unconditional multiple logistic reg...

Moreover, it is not known whether body mass index (BMI) could have a different prognostic impact in screen-detected versus symptomatic breast cancer patients. To investigate these unsolved issues, we carried out a retrospective study evaluating the effect of BMI on breast cancer prognosis in screen-detected vs symptomatic breast cancer patients. We conducted a follow-up study on 448 women diagnosed with incident, histologically-confirmed breast cancer. Patients were categorized according to their BMI as normal weight, overweight and obese. Disease free survival (DFS), overall survival (OS), and BMI curves were compared according to mode of cancer detection. Among screen-detected patients, higher BMI was associated with a significant lower DFS, whereas no significant difference was observed among symptomatic patients. OS showed similar results. In the multivariate ...

Metabolic syndrome (MS)--characterized by central adiposity, insulin resistance, low serum high-density lipoprotein cholesterol (HDL-C), high serum triglyceride and high blood pressure--seems to be strictly correlated to breast carcinogenesis. We enrolled 777 healthy women and women with breast cancer in our nested case-control study to evaluate the association between MS and breast cancer, analyzing anthropometric parameters (weight, height, BMI, waist and hip circumference), blood pressure, serum HDL-C, triglyceride, fasting plasma glucose, insulin, testosterone and uric acid levels and administering a questionnaire about physical activity, food intake, tobacco use, alcohol abuse, personal and familial history of disease. We found an higher prevalence of metabolic syndrome (30%) in postmenopausal breast cancer patients compared to healthy women (1...

We investigated whether the biological features of the primary tumor affect pCR. Forty-six patients treated with capecitabine-oxaliplatin and pelvic conformal radiotherapy were considered. Forty-three patients underwent surgery, and the pathologic response was scored according to the tumor regression grade (TRG) scale. Epidermal growth factor receptor (EGFR), vascular endothelial growth factor, poly(adenosine diphosphate-ribose) polymerase-1, X-ray cross-complimenting, thymidylate synthase (TS) and Ki67 expression were evaluated by immunohistochemistry on rectal biopsies obtained before chemoradiotherapy, and scored as the percentage of positive cells. Cutoffs were selected based on ROC analysis. The correlation between the biological factors and the TRG coded as TRG1 (pCR) versus TRG ≥2 (no pCR) was assessed by the χ(2) test and logistic regression analysis. Low EGFR (p = 0.007), high TS (p = 0.002), and high Ki67 (p = 0.05) were strongly associated with pCR. Upon univariate analysis, TRG significantly affected disease-free survival (p = 0.03). pCR was significantly associated with high TS, high Ki67 and low EGFR expression. Patients with pCR have a significantly lower incidence of relapse.
