Dagrosa","doi":"10.21037/TRO-20-61","DOIUrl":"https://doi.org/10.21037/TRO-20-61","url":null,"abstract":"Background: Boron neutron capture therapy (BNCT) is a binary modality based on the nuclear reaction 10 B (n, α ) lithium-7 ( 7 Li) that has been used to treat a variety of tumors, among these, cutaneous melanoma (CM). In previous boron biodistribution studies in agreement with the personalized oncology, we have demonstrated that boronophenylalanine (BPA) uptake can be correlated with the tumoral temperature and viability. The main aim of these studies was to evaluate the relationship between tumoral temperature and the response to the complete BNCT. Methods: Nude mice were implanted with human melanoma cells (Mel J) and divided into different groups (Control, NCT, BNCT I and BNCT II) and irradiated with the thermal neutron beam from RA-6 (4.96× 10 8 /cm 2 /sec) during 37 and 55 minutes respectively. Tumor and body temperatures were measured by Static Infrared Imaging (SIRI), and it was performed the following up of the animals. Results: Tumor growth showed a complete growth inhibition during the first 20 days after treatment in both BNCT groups (BNCT I and BNCT II vs. Control P<0.001). Considering the analogy between the Fourier’s Law of Heat Conduction and the Ohm’s law of Electrical Conduction, the quantity (T_tum-T_ inf)/(T_body-T_tum) was analyzed as a function of Vf/Vi (Final volume/Initial volume) ratio. A tendency to higher values of the temperature’s ratios, was observed with respect to the degree of tumor control (BNCT I with a R 2 of 0.3527, BNCTII with a R 2 of 0.3327) in agreement with previous boron biodistribution studies. The histology and immunohistochemical studies showed larger areas of necrosis and picnotic regions and a significant decrease of the Ki-67 antibody labeling in the BNCT II group evidencing important tumor damage. Conclusions: tumoral characteristics, especially the temperature, could be used to plan a personalized treatment for each patient. As values of correlation between temperature and tumoral response showed to be weak, we considered to explore a new model of three dimension for heat transport process.","PeriodicalId":93236,"journal":{"name":"Therapeutic radiology and oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43816860","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}

Methods: Nine patients who underwent WBRT were selected for this retrospective study. The hippocampus was contoured, and the hippocampal avoidance regions were created using a 5-mm volumetric expansion around the hippocampus for each patient. Non-coplanar and coplanar VMAT plans were generated for each patient. All treatment plans were generated for a prescribed dose (PD) of 30 Gy in 10 fractions. Results: The average volumes of the hippocampus and hippocampal avoidance region were 2.8±0.38 and 27±2.48 cm 3 , respectively. For coplanar and non-coplanar VMAT plans, the average D 100% of the hippocampus was 8.60 Gy (range, 8.30–8.80 Gy) and 8.56 Gy (range, 8.30–8.90 Gy), respectively, and the average D max of the hippocampus was 15.29 Gy (range, 14.35–15.92 Gy) and 14.99 Gy (range, 13.80–15.83 Gy), respectively. The non-coplanar VMAT plans showed a significantly lower average D max of the lens (4.23 Gy) than did the coplanar VMAT plans (4.77 Gy). The average gamma passing rate for non-coplanar and coplanar VMAT quality assurance (QA) with criteria of 3%/3 mm were 95.4%±2.6% and 95.6%±1.6%, indicating good agreement between the calculated plan dose and the measured dose. Conclusions: We showed that the suggested criteria of the RTOG 0933 trial for the hippocampal dose can be achieved in both coplanar and non-planar VMAT plans.
