The standard treatment is cytoreductive surgery, followed by platinum-taxane based chemotherapy. In patients with advanced disease, a valid option is a neoadjuvant chemotherapy followed by interval debulking surgery. Despite the progress in primary treatment, almost 70% of the patients relapse. There is a significant need for better first-line treatment to avoid or delay relapse and improve ovarian cancer outcomes. The most significant change involves the changes in the treatment schedule and new drugs in first-line chemotherapy. Bevacizumab is approved in first-line treatment combined with carboplatin and paclitaxel as it improves progression-free survival (PFS) in patients with a higher risk of recurrence. After achieving the response to first-line chemotherapy, maintenance therapy with poly-adenosine-diphosphate-ribose-polymerase (PARP) inhibitors prolongs PFS in patients with homologous recombination deficiency (HRD). Patients with BRCA mutations obtain the most significant benefit.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49639494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2017, 3689 people were diagnosed in the Republic of Croatia. Two thousand ninety-five people died of colorectal cancer in 2019. Colorectal cancer is preventable, and it appears that smoking and obesity are factors that affect its onset. Physical inactivity is closely related to obesity, and the question is whether it can be an independent predictor of colon cancer. We searched the literature on Pubmed for the past five years, including systematic reviews and meta-analyses on the association between physical activity and colon cancer incidence. Studies are methodologically diverse and involve different approaches. In most observational studies, greater physical activity is associated with a lower incidence of colon cancer, while in the interventional studies, results were more diverse. In general, smoking tobacco products has a much greater effect on colon cancer development, but physical activity is linked to the onset of the disease and should be one of the prevention measures.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45184186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, we have found that institutional follow-up data are lacking. This retrospective analysis aims to update institutional data on survival and disease control rates. Methods: From 2011 till 2014, 915 breast cancer patients underwent surgery at CHC Rijeka, and 615 were included in this analysis. The Institutional Ethics Committee approved the analysis. Results: All patients were female, and the average age was 59 years. In the 5-year postoperative period, local, regional, and distant recurrence-free survival rates and overall survival and disease-free survival were calculated. All rates negatively correlate with a higher T and N status and a higher stage of the disease. The analysis has also demonstrated that in the pT1-3 pN0-1 subgroup, sentinel lymph node biopsy (SLNB) was not inferior to axillary lymph node dissection (ALND) in terms of locoregional control of disease and overall survival. Conclusion: Besides updating institutional data, the analysis confirmed that overall survival and locoregional control of the disease in the upfront-surgery patients are similar between pN0 and pN1 subpopulations and between pN2 and pN3, but statistically significantly different between pN0-1 and pN2-3. Currently ongoing, prospective observational multicenter clinical trial aims to translate the significance of these results into the neoadjuvant era.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67598494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At UH Rijeka IMRT became the technique of choice for radiation therapy following radical prostatectomy since 2016. Previously, an advanced 3-DCRT technique using the field-in-field (FiF) method was used for dose distribution optimization around target volumes and organs-at-risk. This research has been performed to investigate the influence of planning technique choice (FiF or IMRT) on coverage of target volumes with prescribed dose and organs-at-risk sparing. Materials and methods: Comparison of dose distributions calculated using FiF and IMRT techniques was performed retrospectively for ten patients who underwent postoperative radiotherapy. The prescribed dose for all patients was delivered using IMRT, and for this research, we also calculated dose distributions using the FiF technique. For FiF and IMRT techniques, we used linear accelerator photon beams. To determine the influence of planning technique on dose distribution parameters related to target volumes (GTV, CTV, PTV1, PTV2) were analyzed. For organs-at-risk sparing evaluation (rectum, bladder, femoral heads), we used dose-volume constraints. Results and discussion: The analysis of parameters related to target volumes has shown that most of them had no statistically significant difference (V100%(GTV), V100%(CTV), V95%(PTV2), V95%(PTV1)). For both planning techniques, internationally set dose constraints were achieved. Statistically, we found a significant difference for V100%(PTV2), p=0,000534, and V100%(PTV1), p=0,042944 in favor of IMRT. A statistically significant difference (p=0,045966) was found for the volume of the rectum, which receives 40Gy, and for the volume of femoral heads, which receives 30Gy (p=0,000385), where the sparing is better for IMRT. For dose-volume constraints related to the bladder, no statistically significant differences were found. Conclusion: Results of this research show a statistically significant difference for V100% target volume coverage for PTV1 and PTV2, with better dose coverage accomplished by IMRT. Concerning organs-at-risk sparing, a statistically significant difference in favor of IMRT was found for rectum volume, which receives 40Gy. Expectedly, IMRT was superior to the FiF technique. However, differences between the two planning techniques were relatively small, which points to the fact that the FiF technique is viable as a technique of choice.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43281455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no statistically significant reduction in tumor size, histological grade or the number of positive axillary lymph nodes was detected in newly diagnosed BC compared to those diagnosed over ten years ago. The mean age of BC incidence was 61 years, with the mean tumor size of 22 mm (median 18 mm), in both periods.
