RESUMO

AIM: To assess the prevalence of metabolic syndrome (MetS) and osteoporosis in patients with prostate cancer (PCa) treated with radical radiotherapy (RT) with or without androgen deprivation therapy (ADT). BACKGROUND: Worldwide, the prevalence of MetS is estimated to range from 20% to 25% of the adult population. However, prevalence rates are much higher in PCa patients (pts) who undergo ADT. MATERIALS AND METHODS: Multicentre cross-sectional study of 270 pts in Spain with PCa. Patients were divided into 3 groups based on the duration of ADT (6, 12-18, ≥24 months) and compared to a control group without ADT. MetS was defined according to NCEP ATP III criteria. Osteoporosis was assessed by DEXA. RESULTS: A total of 270 pts, treated from November 2011 to October 2012, were included. Of these, 122 pts (47%) fulfilled the criteria for MetS. The median age of this group was significantly higher (71.3 vs. 69.38 years, p = 0.028). MetS prevalence was 50% in the control group. In pts who received ADT, prevalence was 44.8% after 6 months of ADT, 45.3% after 12-18 months, and 50% after ≥24 months (pns). Most pts (168/270; 62%) underwent DEXA. Of those tested, 78 (46.4%) had osteopenia and only 11 (6.5%) had osteoporosis. CONCLUSIONS: The prevalence of MetS in pts with PCa treated with radical RT was higher (47%) than in the general population. However, there were no significant differences in the duration of ADT administration. The prevalence of osteoporosis was low. These findings suggest that the prevalence of MetS in PCa patients may be higher than previously reported.

RESUMO

Merkel cell carcinoma (MCC) is a rare primary cutaneous carcinoma of the skin who has high aggressiveness, high risk of locoregional and distant spread, a mortality rate considerably higher than that of cutaneous melanoma and a poor survival. Its incidence has increased during the past twenty years. The studies published from 2008 to early 2012 have introduced interesting changes in the understanding of its epidemiology, pathogenesis and consequently in the diagnostic codes and the therapeutic approach. Early and detailed nodal diagnosis with posterior multidisciplinary decision is mandatory. Surgery and Radiotherapy play a fundamental role in the management of this tumor. Both are associated with improved locoregional control and disease free survival; but patients continue to have distant failure because, currently, there is no effective systemic treatment available. Consequently, there remain controversies about its appropriate management, and this review is an attempt to contribute to their clarification.

RESUMO

INTRODUCTION: Anemia is the most common haematological complication in cancer patients. OBJECTIVE: Analysis of the incidence, prevalence and treatment of anemia in oncologic patients treated in Radiation Oncology Departments in Spain (ROD) and monitoring of the existing recommendations for the treatment of anemia. MATERIAL AND METHODS: Observational, prospective, multicenter study which involved 19 Spanish ROD. The study was approved by the CEIC Central Defense Hospital. 477 patients with solid tumors, subsidiary of RT with radical intent referred to such centers within a period of one month (5/5/09 to 5/6/09) and gave their consent to participate in the study. We gathered the main characteristics of patients and their oncologic disease. All patients underwent a determination of Hb levels before RT, upon reaching 25-35 Gy and at the end treatment. In patients with anemia we assessed the existence of related symptoms and its treatment. RESULTS: Basal situation: The prevalence of anemia was 34.8% (166 patients). Mean Hb in patients with anemia was 11.17 ± 1.07 g/dl. Anemia-related symptoms were present in 34% of the patients. Anemia predisposing factors were: stage of the disease, previously received chemotherapy, and hormonal therapy. 39% (66 patients) received anemia treatment, with a mean Hb of 10.43 ± 1.04 g/dl. During RT: The prevalence of anemia was 38.9% (182 patients) with a mean Hb of 11.24 ± 1.21 g/dl. Predisposing factors for anemia during RT treatment were: age, male sex, chemotherapy prior to RT, basal anemia and chemotherapy during RT. 36.3% (66 patients) had anemia-related symptoms. 34.6% (63 patients) with a mean Hb of 10.5 ± 1.37 g/dl received treatment for anemia. The prevalence of anemia at the end of the RT was 38.1% (177 patients) with a mean Hb of 11.19 ± 1.18 g/dl. The predisposing factors for the appearance of anemia at the end of RT were: male sex, anemia at basal situation and during treatment and chemotherapy during RT. 34% (61 patients) had anemia-related symptoms and 73 patients (41.2%) with a mean Hb of 10.5 ± 1.22 g/dl received treatment for anemia. The presence of anemia-related symptoms was significantly correlated with the beginning of treatment for anemia. The incidence of anemia (new cases) during radiotherapy was 17.5%. CONCLUSION: The prevalence of anemia in basal situation, during RT and at the end of RT is 34.8%, 38.9% and 38.1%. During RT the incidence of anemia is 17.5%. 39.8%-41.2% of patients with anemia and 64.2%-68% of patients with anemia-related symptoms received treatment. Treatment of anemia starts with Hb<11 g/dl and the goal is to achieve Hb 12 g/dl. In our Radiotherapy Oncology Departments, the treatment of anemia complies with the current recommendations and guidelines in use.
