After Benjamini\u2013Hochberg correction of multiple testing we found that 9 months after LDR therapy the chromosome aberration values (dicentrics + rings, chromatid deletions, total aberration and aberrant cell values) correlated positively and significantly with the largest ISVs, namely V<sub>1%<\/sub>, V<sub>1Gy<\/sub>.<!--more--> The correlations were weak, between 0.37 and 0.45 (Table 2). In HDR therapy, 3 months after radiotherapy dicentric plus rings correlated positively and weakly with most ISVs (Table 3). Aberrant cell number correlated with V<sub>150%<\/sub> at this time point as well (Spearman correlation coefficient 0.41). We found no correlations in any other time points of the follow-up. In the EBRT treatment group, the ISVs showed significant positive correlations with various chromosome aberrations directly after the radiotherapy, at the 3rd, 6th and at the 12th month. The aberrations which correlated with the most ISVs are shown in Table 4. Furthermore, the Spearman correlation coefficient for V<sub>10Gy<\/sub> are 0.52 and 0.51 for dicentrics + rings and aberrant cells at 3 months, respectively. The frequency of chromatid breaks and aberrant cells correlated with V<sub>10Gy<\/sub> (Spearman correlation coefficient 0.50 and 0.56) and aberrant cell number with V<sub>10%<\/sub> (0.49) at 6 months. Total aberrations (0.48) and aberrant cell number (0.43) showed correlation with V<sub>10Gy<\/sub> at 12 months.<\/p>\n<p>Univariate regression analysis was performed to explain the variance of chromosome aberrations by variables of ISVs. Multiple regression cannot be used, because of the high collinearity of the variables. We sumini\u2013Hochberg correction in Tables 4 and 5. In case of LDR therapy, we found, that none of the ISVs were significant predictors of chromosome aberrations (p &gt; 0.2 R 2 &lt; 6.4% at the ninth month after therapy). However, at the third month after HDR the predictive value (R 2 ) varied between 26.0 and 31.7, the best predictor being V<sub>100%<\/sub> (p = 0.004, R 2 = 31.7%) (Table 5). We also found significant regression models 12 months after the HDR irradiation, where we received no significant correlations. The R 2 ranged between 15.5% and 20.5% and the concerned aberrations were chromatid breaks, total aberrations and aberrant cell values (Table 5). After EBRT, the data of the regression models of time-points directly after radiotherapy and 9 months later are shown in Table 6. Furthermore, we also found significant regression models at 6 months after the therapy (V<sub>10%<\/sub> and chromatid deletions: R 2 = 19.5) and 12 months after the therapy (dicentrics and rings with V<sub>1%<\/sub> and V<sub>1Gy<\/sub>, R 2 = 20.1 and 18.7, respectively). On the other hand, less regression relation was found than with rank correlation. R 2 was between 17.3 and 49.4%, the highest value was calculated for the relationship of V<sub>10%<\/sub> and the total aberrations 9 months after the therapy.<\/p>\n<h2>Conversation<\/h2>\n<p>Brachytherapy, specifically LDR treatment therapy is very difficult to model inside the phone countries since the dose birth out-of LDR procedures lasts everything 1 year.

Although the base level knowledge of the brand new laws out-of radiobiology is additionally understood in this condition, the fresh new summarised feeling of one&#8217;s multiple different factors-energy, amount rate, procedures time, irradiated volume-for the chromosome aberrations is actually not familiar.
