RESUMO
BACKGROUND: To reach a consensus on recommendations for the management of high-risk and post-operative non-metastatic prostate cancer by a group of Radiation Oncologists in Catalonia dedicated to prostate cancer. METHODS: A modified Delphi approach was employed to reach consensus on controversial topics in Radiation Oncology on high-risk non-metastatic (eight questions) and post-operative (eight questions) prostate cancer. An agreement of at least 75% was considered as consensus. The survey was electronically sent 6 weeks before an expert meeting where topics were reviewed and discussed. A second-round survey for the controversial questions only was sent and answered by participants after the meeting. RESULTS: After the first round of the survey, 19 experienced Radiation Oncologists attended the meeting and 74% fulfilled the second-round online questionnaire. An agreement of 9 of the 16 questions was accounted for the first round. After the meeting, an additional agreement was reached in 3 questions leading to a final consensus on 12 of the 16 questions. There are still controversial topics like the use of PET for staging of high-risk and post-operative non-metastatic prostate cancer and the optimal dose to the prostate bed in the salvage setting. CONCLUSION: This consensus contributes to establish recommendations and a framework to help in prostate cancer radiation therapy and pharmacological management in daily clinical practice of high-risk and post-operative non-metastatic prostate cancer.

BACKGROUND: Studies have shown that breast infiltrating ductal carcinoma develops from precursor lesions or pre-invasive. It is accepted that the risk of invasive ductal carcinoma increased slightly in hyperplasia, but especially in cases of atypical hyperplasia and intraductal carcinoma. OBJECTIVES: To evaluate and compare the nodal status between ductal breast cancer with in situ component (group 1) or without it (group 2). MATERIAL AND METHOD: Descriptive and retrospective study that included 454 ductal breast cancers. Data concerning clinical and pathological variables was collected. All data was compared between both groups. RESULTS: Among all cases, 176 (38.8%) showed positive lymph nodes, 136 patients (39.5%) from group 1 and 40 cases (36.4%) from group 2. Among group 1 cases, high-grade subgroup showed higher positive lymph node rate (82 cases, 55.4%) than the extensive in situ carcinomas subgroup (84 cases, 49.7%). Both of them had a significant higher rate than group 2 cases (p = 0.003 y p = 0.028, respectively). Moreover, the low-grade in situ carcinomas without cellular necrosi had positive lymph nodes just in 30 cases (24%), significantly lower (p = 0.034) than group 2. CONCLUSIONS: We did not find overall statistical differences between groups depending on in situ associated component. But when we analyzed in situ subgroups, we found differences with higher positive lymph node rate in high grade carcinomas and extensive in situ carcinomas subgroups, while lower affectation rates were observed in low grade carcinomas (without cellular necrosis), compared to the group of breast cancers without in situ component associated.

INTRODUCTION: Prostate cancer (PC) is one of the tumours with the highest incidence in recent years. PC therapies have several adverse effects. A panel consensus recommendation has been made to prevent or ameliorate complications in PC treatment to improve quality of life. MATERIAL AND METHODS: Fifteen specialists have met to analyse the different toxicities associated with PC treatment. Each medical specialist performed a National Library of Medicine PubMed search citations searching about these secondary effects and his specialty from 1999 to 2009 to propose measures for their prevention/amelioration. RESULTS: Surgery is associated with incontinence and impotence. Radiotherapy can produce acute, late urological and gastrointestinal toxicity. Brachytherapy can produce acute urinary retention. Chemotherapy is associated with haematotoxicity, peripheral neuropathy and diarrhoea, and hormone therapy can produce osteoporosis, metabolic syndrome, cognitive and muscular alterations, cardiotoxicity, etc. CONCLUSIONS: Improvement in surgical techniques and technology (IMRT/IGRT) can prevent surgical and radiotherapeutic toxicity, respectively. Brachytherapy toxicity can be prevented with precise techniques to preserve the urethra. Chemotherapy toxicity can be prevented with personalized schedules of treatment and close follow-up of iatrogenia and hormone therapy toxicity can be prevented with close follow-up of possible secondary effects.
