Plaque Brachytherapy

Background: In several malignancies, gender-based survival differences after specific therapeutic interventions have been demonstrated. It is not known whether such differences exist after plaque brachytherapy of uveal melanoma. Methods: All patients who received brachytherapy for uveal melanoma at St. Erik Eye Hospital from November 1, 1979 through November 20, 2017 were included (n = 1,541). Retrospective data were retrieved including baseline patient and tumor characteristics, brachytherapy nuclide (ruthenium-106 or iodine-125), radiation dose, treatment duration, tumor relapses, date of metastasis, and cause of death. Results: A total of 775 men and 766 women were treated with plaque brachytherapy. There were no significant differences between the genders in baseline characteristics, treatment, or follow-up. Men and women had similar rates of tumor relapses, hazard for repeated brachytherapy (men vs. women 0.8, p = 0.47), enucleation-free survival, and survival after detection of metastasis. Five-, 10-, and 15-year melanoma-related mortality was 14, 24, and 27% for men and 15, 26, and 32% for women, respectively. There were no significant differences in hazard for melanoma-related mortality (men vs. women 0.9, p = 0.32), median Kaplan-Meier disease-specific survival (men 18.2 years, women 15.5 years, p = 0.22), or median overall survival (men 13.5 years, women 12.6 years, p = 0.60). Conclusion: There are no relevant differences between men and women in ocular or patient survival after brachytherapy for uveal melanoma.

Plaque Brachytherapy

BackgroundEpiscleral brachytherapy is the most common eye-preserving treatment for medium-sized choroidal melanomas. γ-emitting iodine-125 (125I) and β-emitting ruthenium-106 (106Ru) are widely used. The latter is however generally reserved for thinner tumours (<6 mm). In this study, we compare ocular and patient survival in thicker tumours treated with the respective radioisotope.MethodsAll patients with ≥5.5 mm thick choroidal melanomas who were treated with plaque brachytherapy at a single institution between 1 November 1979 and 31 December 2015 were included (n=571). Size-controlled Cox regression HRs for postbrachytherapy enucleation, repeated brachytherapy and melanoma-related mortality were calculated, as well as Kaplan-Meier disease-specific survival and relative 10-year survival in matched subgroups.Results317 patients were treated with 106Ru and 254 with 125I. The rate of repeated brachytherapy was significantly higher among patients treated with 106Ru (8%) than with 125I (1%, p<0.001). Size-controlled Cox regression HRs for postbrachytherapy enucleation (125I vs 106Ru 0.7, p=0.083) and melanoma-related mortality were not significant (125I vs 106Ru 1.1, p=0.63). Similarly, Kaplan-Meier disease-specific and relative 10-year survival was comparable in matched groups of 5.5–7.4 mm (relative survival 106Ru 59%, 125I 56%) and ≥7.5 mm thick tumours (relative survival 106Ru 46%, 125I 44%).ConclusionsRates of repeated brachytherapy were significantly higher among patients treated with 106Ru versus 125I for thick choroidal melanomas. There were, however, no significant differences in rates of enucleation or patient survival.

Abstract Background Tumor regression of uveal melanomas (UMs) after radiotherapy has been reported as a valuable prognostic factor for metastasis and metastatic death. But its effect on prognosis is questionable. The purpose of this study was to summarize the regression features of uveal melanoma after iodine-125 plaque brachytherapy and the relationship with prognosis. Methods Adult uveal melanoma patients who only received iodine-125 plaque brachytherapy between December 2009 and March 2018 at the Beijing Tongren Hospital, Capital Medical University were enrolled in this study. The regression rate was calculated as the percent change in tumor height, and each eye was classified for four main regression patterns: Decrease (D), Stable (S), Others (O), and Increase (I), according to the trend of height change. Statistical analysis was performed using one-way ANOVA and chi-square test, univariate and multivariate logistic regression, and Kaplan-Meier analysis. Results A total of 139 patients was included in the study. The median follow-up was 35 months. Regression patterns status was pattern D in 65 tumors (46.8%), pattern S in 50 tumors (36.0%), pattern O in 6 tumors (4.3%), and pattern I in 18 tumors (12.9%). Reductions of tumor mean height for each follow-up visit were 5.26% (3 months), 10.66% (6 months), 9.37% (12 months), and 14.68% (18 months). A comparison (D vs. S vs. O vs. I) revealed the preoperative height of pattern I was significantly lower than the pattern D, S and O (mean: 7.24 vs. 7.30 vs. 6.77 vs. 5.09 mm, respectively; P = 0.037). LBD (largest basal diameter) was strongly associated with the metastasis (P = 0.03). However, an association between the tumor regression and subsequent melanoma-related metastasis and mortality could not be confirmed (P = 0.66 and P = 0.27, respectively). The tumor regression rate increased with increasing tumor height (P = 0.04) and decreased with increasing of LBD (P = 0.01). Conclusion Our study showed a lack of association between the prognosis and the regression of uveal melanomas following I-125 plaque radiotherapy. The LBD and original height of the tumor have predictive value in tumor regression rate, and LBD was positively associated with metastasis.

BackgroundAlthough T4b is known to have worse oncologic outcomes, it is unclear whether it truly shows a worse prognosis. This study aims to compare the survival differences between T4a and T4b.MethodsPatients who were pathologically diagnosed with T3 and T4 colorectal adenocarcinoma from 2010 to 2014 were included (T3, n = 1822; T4a, n = 424; T4b, n = 67). Overall survival (OS) and cancer-specific survival (CSS) were compared between T4a and T4b using the Kaplan-Meier method and log-rank test.ResultsIn stage II, T4a had better OS and CSS than T4b (5-year OS, 89.5% vs. 72.6%; 5-year CSS, 94.4% vs. 81.7%, all p &lt; 0.05), however, in stage III, there were no significant differences in survivals between groups (all p &gt; 0.05). In multivariable analysis, T classification was not an independent risk factor for OS (p &gt; 0.05). However, for CSS, when respectively compared to T3, T4b (HR 3.53, p &lt; 0.001) showed a relatively higher hazard ratio than T4a (HR 2.27, p &lt; 0.001).ConclusionsT4a showed more favorable OS and CSS than T4b, especially in stage II. Our findings support the current AJCC guidelines, in which T4b is presented as a more advanced stage than T4a.

Background/Aims: The aim of this study is to report the burden of ocular morbidity following iodine-125 episcleral plaque brachytherapy (EPBT) in the treatment of American Joint Committee on Cancer (AJCC) T4-staged posterior uveal melanoma (PUM). Methods: Clinical records of patients with T4-staged PUM treated with 125I EPBT were analyzed for incidence of treatment failure and radiation-induced complications. Results: Cumulative incidence of local treatment failure was 9% (95% CI 5–15%) at 5 years and was associated with decreased tumor height (HR = 0.78; p = 0.01). Cumulative incidence of enucleation at 5 years was 21% and was correlated with worsening baseline visual acuity (HR = 1.42; p = 0.05). Increasing patient age was associated with higher rates of vitreous hemorrhage (HR = 1.03; p = 0.02) and cataract surgery (HR = 1.05; p < 0.001). Increased tumor height was associated with higher rates of neovascular glaucoma (HR = 1.16; p = 0.03) and vitreous hemorrhage (HR = 1.23; p < 0.001). Conclusion: 125I EPBT is an effective treatment for T4-staged PUM and achieves high rates of local control. Treatment failure appears to be more common among minimally elevated tumors. Other causes of ocular morbidity were associated with increasing tumor height, patient age, and baseline visual acuity.

While it is generally recognized that anatomical differences exist between the male and female knee, the literature generally refutes the clinical need for gender-specific total knee prostheses. It has been found that standard, unisex knees perform as well, or better, in women than men. Recently, high-flex knees have become available that mechanically accommodate increased flexion yet no studies have directly compared the outcomes of these devices in men and women to see if gender-based differences exist. We retrospectively compared the performance of the high-flex Vanguard knee (Biomet, Warsaw, IN) in 716 male and 1,069 female knees. Kaplan-Meier survivorship was 98.5% at 5.6–5.7 years for both genders. After 2 years, mean improvements in Knee Society Knee and Function scores for men and women (50.9 versus 46.3; 26.5 versus 23.1) and corresponding SF-12 Mental and Physical scores (0.2 versus 2.2; 13.7 versus 12.2) were similar with differences not clinically relevant. Postoperative motion gains as a function of preoperative motion level were virtually identical in men and women. This further confirms the suitability of unisex total knee prostheses for both men and women.

Abstract Background: Choroidal malignant melanoma is a rare intraocular cancer in Asian Indian population. There is a paucity of data from our population comparing iodine 125 (I-125) brachytherapy and enucleation. Aim: This study aims to compare two groups of choroidal melanoma patients treated with either I-125 brachytherapy or enucleation in the Asian Indian population. Objectives: To evaluate the long-term morbidity and mortality rates in choroidal melanoma patients treated with either I-125 brachytherapy or enucleation. Methods: It is a retrospective study involving forty four eyes, diagnosed with choroidal melanoma from May 2008 to February 2015. All were evaluated preoperatively for metastasis. Twenty-two underwent globe salvaging I-125 brachytherapy surgery whereas remaining 22 underwent globe destructive primary enucleation procedure. Results: At a mean follow-up 39 months, 2 of 22 cases (9%) died in the brachytherapy group. One was secondary to metastasis in the liver while the other case died of a natural cause. In the enucleation group also, there were two deaths (9%) secondary to metastasis. The metastasis free survival was 95% in the brachytherapy group and 91% in the enucleation group, which was not statistically significant (P = 0.3577). Kaplan–Meier survival at 3 years and 5 years was 95% and 89% for brachytherapy group and 94% and 89% for enucleation group. Conclusion: This study found no difference in the long-term survival of choroidal melanoma patients treated with either brachytherapy or enucleation in the Asian Indian eyes.

Reports on the long-term survival effect of edaravone, which was approved for the treatment of amyotrophic lateral sclerosis (ALS) in 2015 in Japan, are rare. Herein, we report our retrospective analysis of 45 consecutive patients with ALS who initially visited our hospital between 2013 and 2018. Of these, 22 patients were treated with edaravone for an average duration of 26.6 (range, 2–64) months, whereas the remaining patients were not treated with edaravone and comprised the control group. There were no differences in baseline demographics between the two groups. The primary endpoint was tracheostomy positive-pressure ventilation (TPPV) or death, and the follow-up period ended in December 2020. The survival rate was significantly better in the edaravone group than in the control group based on the Kaplan–Meier analysis, which revealed that the median survival durations were 49 (9–88) and 25 (8–41) months in the edaravone and control groups, respectively (p = 0.001, log-rank test). There were no serious edaravone-associated adverse effects during the study period. Overall, the findings of this single-center retrospective study suggest that edaravone might prolong survival in patients with ALS.
