The Burden of Cervical Cancer in Korea: A Population-Based Study.

This study used the Korean National Health Insurance (NHI) claims database from 2011 to 2017 to estimate the incidence and the incidence-based cost of cervical cancer and carcinoma in situ of cervix uteri (CIS) in Korea. The primary outcome was the direct medical cost per patient not diagnosed with cervical cancer (C53) or CIS (D06) 2 years prior to the index date in the first year after diagnosis. A regression analysis was conducted to adjust for relevant covariates. The incidence of cervical cancer tended to decrease from 2013 to 2016, while that of CIS increased. In particular, the incidence rate of CIS in women in their 20 s and 30 s increased by 56.8% and 28.4%, respectively, from 2013 to 2016. The incidence-based cost of cervical cancer and CIS was USD 13,058 and USD 2695 in 2016, respectively, which increased from 2013. Multivariate regression analysis suggested that age was the most influential variable of the cost in both patient groups, and the cost was highest in those aged over 60, i.e., the medical cost was significantly lower in younger women than their older counterparts. These findings suggest that targeting younger women in cervical cancer prevention is a reasonable option from both economic and public health perspectives.

Comparative Effectiveness of Esophagectomy Versus Endoscopic Treatment for Esophageal High-grade Dysplasia.

OBJECTIVE: The purpose of this study is to determine the comparative effectiveness of esophagectomy versus endoscopic mucosal resection followed by radiofrequency ablation (EMR-RFA) for the treatment of Barrett esophagus with high-grade dysplasia (HGD). BACKGROUND: HGD of the esophagus may be managed by surgical resection or EMR-RFA. National guidelines suggest that EMR-RFA is effective at eradicating HGD. The comparative effectiveness and cost-effectiveness of EMR-RFA versus esophagectomy for HGD remains unclear. METHODS: A decision-analysis model was constructed to represent 3 management strategies for HGD: (1) esophagectomy, (2) EMR-RFA, and (3) endoscopic surveillance. Estimates for model variables were obtained from literature review, and costs were estimated from Medicare fee schedules. Costs and utilities were discounted at an annual rate of 3%. The baseline model was adjusted for alternative age groups and high-risk dysplastic variants. One-way and multivariable probabilistic sensitivity analyses were conducted. RESULTS: For a 65-year-old patient, compared to esophagectomy, EMR-RFA yields equivalent utility (11.5 vs 11.4 discounted quality-adjusted life years) with lower total cost ($52.5K vs $74.3K) over the first 20 years. Dominance of EMR-RFA over esophagectomy persists for all age groups. Patients with diffuse or ulcerated HGD are more effectively treated with esophagectomy. Model outcomes are sensitive to estimated rates of disease progression and postintervention utility parameters. CONCLUSIONS: Existing evidence supports EMR-RFA over esophagectomy for the treatment of esophageal HGD. Long-term outcomes and more definitive quality-of-life studies for both interventions are crucial to better inform decision-making.

Effectiveness of skin cancer screening for individuals age 14 to 34 years.

BACKGROUND: Approximately 15 % of all cases of melanoma are diagnosed before age 35 years. In Germany, individuals ≥ 35 years are eligible for the national skin cancer screening program. The effectiveness of a population-based skin cancer screening in general and in particular for young adults is unclear. OBJECTIVES: Assessment of the effectiveness of a skin cancer screening program and of risk factors for detection of a melanoma/atypical nevus in the setting of a screening for the age group 14 to 34 years. METHODS: A total of 12,187 individuals age 14 to 34 years were screened in Saxony for skin cancer by a dermatologist in the program "Haut-Check 14-34 Jahre" of the AOK PLUS, a large German health insurance, between January and July 2009. Demographic, clinical and histopathological data and UV-exposure data were collected from each participant. Multivariate logistic regression models were used to assess risk factors for the detection of a (histopathologically confirmed) melanoma or atypical nevus. RESULTS: 2.8 % of the eligible individuals participated in the skin cancer screening program with women being more likely to do so. In 1 072 individuals (8.8 %) screening included at least one excision of a skin lesion leading to the diagnosis of melanoma in two participants, melanoma in situ in four persons, and atypical nevus in 641 persons. Use of tanning beds, higher age, number of nevi, and previous cutaneous excision were independent risk factors for the detection of a melanoma or atypical nevus. CONCLUSIONS: In 5.5 % of all cases skin cancer screening resulted in the excision of a malignant or atypical melanocytic lesion. It remains unclear what proportion of these cases would have been detected in routine care. The rate of excisions per newly diagnosed melanoma was 179 : 1. Further investigations are necessary to explore the reasons for this low diagnostic specificity. This study highlights the possibilities and limitations of routine data to evaluate screening programs and indicates the need to collect additional information on healthcare utilization behaviour.
