Abstract

Background: In Japan, the Endoscopic Surgical Skill Qualification System (ESSQS) is used to evaluate surgical skills essential for laparoscopic surgery, but whether surgeons with this certification as operators improve the short‐term outcomes and prognosis after rectal cancer surgery is unclear. This cohort study was designed to compare the short‐term and long‐term outcomes of laparoscopic surgery for advanced rectal cancer performed by an ESSQS‐certified surgeon versus a surgeon without ESSQS certification. Methods: The outcomes of cStage II and III rectal cancer surgery cases performed at 56 Japanese hospitals between 2014 and 2016 were retrospectively reviewed. To examine the impact of ESSQS‐certified surgeons as surgeons, the outcomes of cases with only ESSQS‐certified surgeons as operators were compared with those without involvement of ESSQS‐certified surgeons. Results: A total of 3197 cases were enrolled, with 1015 in which surgery was performed by ESSQS‐certified surgeons, and 544 in which there was no involvement of ESSQS‐certified surgeons. After propensity score matching, the ESSQS group had significantly shorter operative time (p < 0.001), a lower conversion rate to open surgery (p < 0.001), and more dissected lymph nodes (p = 0.002). Conclusion: Laparoscopic rectal surgery performed by ESSQS‐certified surgeons was significantly associated with improved short‐term outcomes. This demonstrates the utility of the ESSQS certification system. [ABSTRACT FROM AUTHOR]

Abstract

Objectives: To evaluate the one-year outcomes of intravitreal ranibizumab biosimilar (RBZ-BS) injections for myopic choroidal neovascularization (mCNV) in Japanese patients. Methods: Twenty-one patients (mean age 69.0 years; 4 males, 17 females) with high myopia and mCNV were retrospectively reviewed. Twelve were treatment-naïve, and nine had previous anti-VEGF treatments. Efficacy measures included best-corrected visual acuity (BCVA) and central macular thickness (CMT). Results: The treatment-naïve group showed significant BCVA improvement from 0.55 ± 0.34 at baseline to 0.24 ± 0.28 at 12 months. The previously treated group had no significant BCVA changes. CMT significantly decreased in both groups: from 295.3 ± 105.2 µm to 207.3 ± 63.0 µm in the treatment-naïve group, and from 196.1 ± 62.0 µm to 147.2 ± 50.1 µm in the previously treated group. Dry macula rates were high: 83% at 3 months and 83% at 12 months in the treatment-naïve group, and 67% at 3 months and 89% at 12 months in the previously treated group. No adverse events were reported. Conclusions: These findings indicate that RBZ-BS is an effective and safe treatment for mCNV, particularly in treatment-naïve patients. The use of RBZ-BS offers a cost-effective alternative to original ranibizumab, reducing financial burdens while maintaining high therapeutic efficacy. Further studies with larger sample sizes and longer follow-up periods are needed to confirm these results and evaluate long-term outcomes and cost-effectiveness. [ABSTRACT FROM AUTHOR]

Abstract

Objective: To purpose of this study was to retrospectively evaluate the 1-year outcomes and factors associated with the treatment responsiveness of switching to intravitreal brolucizumab (IVBR) for neovascular age-related macular degeneration (nAMD) in Japanese patients refractory to ranibizumab or aflibercept using a treat and extend (TAE) regimen. Methods: A total of 48 eyes of 47 nAMD patients were switched to IVBR, and 36 eyes of 35 patients (27 males and 8 females) underwent 1-year treatment after the switch. Results: The rate of dry macula was significantly higher 12 months after the switch to IVBR (p < 0.001), with a significant decrease in the mean central macular thickness (CMT) and the mean central choroidal thickness (CCT) (p < 0.01 and p < 0.01, respectively). The injection interval was significantly extended from 7.0 ± 1.7 weeks to 10.3 ± 2.5 weeks 12 months after the switch (p < 0.001). In the multivariate analysis, a smaller number of prior anti-VEGF injections (p = 0.025; odds ratio: 0.947; 95% confidence interval: 0.903–0.994) and a pre-switching CCT of less than 250 µm (p = 0.023; odds ratio: 0.099; 95% confidence interval: 0.013–0.731) were associated with the good response group. Conclusions: These results suggest that IVBR may suppress disease activity and prolong the injection interval by switching for AMD patients with an insufficient response to treatment with ranibizumab and aflibercept.
