2. A Cost-Effectiveness Analysis of Adjuvant Trastuzumab Regimens in HER2-Positive Early Breast Cancer
Chinese Pharmaceutical Journal 2017;52(8):696-701
OBJECTIVE: To advocate Patient Assistant Program Projects (PAP Projects) decision-making, this study assesses the long-term cost-effectiveness of 1-year adjuvant trastuzumab therapy for women with human epidermal growth factor receptor 2 (HER2) positive early breast cancer. METHODS: A Markov model tracked yearly patients' transitions between five health states. The cycle length was 1 year and the sum was 45. From the perspective of the China health insurance system, the direct medical cost was estimated based on a survey of clinical expert panels. A discounting rate of 3% was used to discount direct medical cost and health outcomes. Utility and transition probabilities were retrieved from the HERA trial and literature. To estimate the direct medical cost, a survey of clinical expert panels was conducted. The cost of trastuzumab and HER2 test based on Roche. The key factor of the model was realized by one-way sensitivity analysis. The result of a probability sensitivity analysis conducted by Monte Carlo simulation was expressed as an incremental cost-effectiveness scatter plot. RESULTS: Without PAP Projects in Guangzhou, the adjuvant trastuzumab treatment prolonged 1.79 QALYs when the cost increased ¥53 301 and the Incremental cost-effectiveness ratio (CER) was ¥29 731/QALY, which is cost-effective based on Guangzhou's per capita GDP in 2015. With PAP Projects, the adjuvant trastuzumab treatment was totally cost-effectiveness. The sensitivity analysis demonstrated that the model was moderate. CONCLUSION: One year adjuvant trastuzumab treatment is a cost-effective therapy for patients with HER-2 positive breast cancer. With PAP Projects in Guangzhou, the adjuvant trastuzumab treatment is projected to be associated with improved QALYs and reduces direct medical costs, compared with the standard chemotherapy, represents a dominant treatment option among patients with HER2-Positive Early Breast Cancer. PAP Projects in Guangzhou should be persisted and spread in China.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.

Chinese Journal of Medical Imaging Technology 2019;35(3):395-399
Objective: To explore the relationship of right collateral ischemic colitis (IC) and calcified plaque of superior mesenteric artery (SMA). Methods Totally 605 patients who underwent CTA of SMA were enrolled and analyzed retrospectively, including 81 patients in IC group and 524 patients in the non-IC group. The detection rate of SMA calcified plaque was compared between the 2 groups. The number, morphology and location of SMA calcified plaque, as well as the degree of stenosis of the opening and the narrowest part of SMA in IC group and the non-IC group were analyzed and compared, and the ROC curve was used to evaluate the efficacy of SMA stenosis degree in diagnosis of IC. Results The incidence of SMA calcified plaques in IC group (13/81, 16.05%) was higher than that in non-IC group (33/524, 6.30%; P=0.002). The number of SMA calcified plaques in IC group was more than that in the non-IC group (P=0.043). Significant difference in the location of calcified plaque was found between the 2 groups (P<0.001). SMA calcified plaques mostly located in the distal segment in IC group, while in the proximal or middle segment in non-IC group. There was no significant difference of plaque morphology between the 2 groups (P=0.421). Statistically significant difference of the narrowest stenosis degree was detected between the 2 groups (P<0.001). The AUC of the narrowest stenosis degree in diagnosis of IC was 0.838 (P<0.001), the sensitivity was 76.92% (10/13), and the specificity was 87.88% (29/33). Conclusion When there are more calcified plaques located in the distal segment of SMA and stenosis degree of the narrowest segment of SMA ≥25%, IC should be considered.
