Penile cancer: prognostic and predictive factors in clinical decision-making.

Penile cancer (PC) is a typical tumor of non-industrialized countries. The incidence is 20-30 times higher in Africa and South America, considering the elevated prevalence of sexually transmitted diseases. Histologically, PC includes squamous cell carcinoma (SCPC), the most frequent, and nonsquamous carcinoma (NSCPC). Early diagnosis is the goal, whereas later diagnosis relates to poor functional outcomes and worse prognosis. The 5-year survival rate is 85% for patients with histologically regional negative lymph nodes, compared to 29%-40% for those with histologically regional positive lymph nodes. To date no new drugs are approved, and there are few new data about molecular mechanisms underlying tumorigenesis. The SCPC remains a rare tumor and the current therapeutic algorithm is based principally on retrospective analysis and less on prospective trials. In this review article, biomarkers of prognosis and efficacy of current treatments are summarized with a focus on those that have the potential to affect treatment decision-making in SCPC.

Advanced/metastatic bladder cancer: current status and future directions.

In 2015 bladder cancer was the fourth most frequent malignancy and the eighth cause of death for cancer. At diagnosis, about 30% of bladder cancer (BC) patients present a muscle-invasive bladder cancer (MIBC) and 5% a metastatic bladder carcinoma (MBC). For fit MBC patients, combination chemotherapy (CC) is the standard of care for first-line treatment. CC includes both the treatment with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) either the classical or the dose-dense MVAC regimen, and the doublet therapy with cisplatin and gemcitabine (CG). Median progression free survival (PFS) was 7 months and median overall survival (OS) was 15 months. The present review provides an update on the management of MBC, with focus on target therapies, immune checkpoint inhibition, looking for prognostic and predictive factors.

Different reactivity against HCV proteins (RIBA 3) according to progression of liver damage.

BACKGROUND: Aim of the study was to assess the correlation between clinical stage of HCV-related liver disease and viraemia to immune response to different viral antigens. METHODS: We considered 1330 patients with HCV chronic infection followed up from 6 months up to 6 years divided into two groups according to RIBA 3 (Abbott) response: Group I, 1231 patients with positivity for at least two bands (83 subjects with asymptomatic infection, 941 with chronic hepatitis, 201 with cirrhosis and 6 with HCC); Group II, 99 patients with positivity at only one band (45 with asymptomatic infection, 53 with chronic hepatitis and 1 cirrhotic). RESULTS: We noticed a major percentage of positive patients for at least three bands in more severe clinical forms (90% of chronic hepatitis or cirrhosis versus 60% of asymptomatics, p < 0.005, chi 2 test). Moreover we noticed a percentage increase of positivity for antibodies anti-c100 and anti-NS5 with the progression of liver damage, statistically significant differences between asymptomatics and patients with chronic forms. We also observed that viraemia is related neither to clinical stage nor to different reactivity to RIBA 3, albeit viraemia is usually detected more frequently among patients with liver damage, but unrelated to different reactivities. CONCLUSIONS: Our results show a clear correlation between number of reactivities towards HCV proteins and progression of liver damage, pointing out that immune response plays a direct role in the long-term outcome of HCV infection.

[Control study of bacterial infections in patients with carcinoma of the breast subjected to radical mastectomy]. / Studio controllo delle infezioni batteriche nelle pazienti affette da carcinoma della mammella sottoposte a mastectomia radicale.

Surgical patients have a high risk of infections. In the breast surgery, a "clean" surgery, the infection rate should not be more than 2%. In this work, we have studied 174 women with breast cancer, which did not receive the antibiotic prophylaxis. After surgery the patients were monitored for infective complications. The total incidence of infections was 5.1%: 3.4% of surgical wound infections and 1.7% of nosocomial infections. The preoperative antibiotic therapy should not be used in the "clean" surgery, as the mastectomy, except in the patients with high infective risk. In fact we can prevent the wound infections of breast surgery with adequate control measures about the aseptic procedures of operating suite, the members of the surgical team and the preparation of the patient.
