Introduction: Explore the impact of the Lung Cancer Screening Trial (NLST-September-2011) and the Medicare approval for CT-screening (CT-LCS-AP-February-2015) on lung cancer incidence rates, mortality, and the percentage of early-stage lung cancer diagnosis (ESLCD-T1-T2N0M0)., Methods: Retrospective interrupted time series analysis using SEER-18 database. All individuals with lung cancer (LC) diagnosis from 2006 to 2016 were included. The effect of NLST and CT-AP-2015 on the monthly percentage of early-stage ESLCD was the primary outcome, additionally LC incidence and mortality rates were calculated. The analysis was performed by age, sex, race, marital status, insurance status, and household income. Bivariate and multivariate models were used to identify predictors of ESLCD., Results: The study cohort was composed by 388,207 individuals, 69 years old in average, 46.6 % female, and 81.1 % white. LC incidence and mortality rates declined from 2006 to 2016 without association with NLST-September-2011 and CT-LCS-AP-February-2015. The percentage of ESLCD increased over time for all groups. Overall rates of ESLCD started at 18 % in January-2006 and increased to 25 % by December-2016. The intervention NLST-2011 did not show an impact in the ESLCD while the CT-AP-2015 showed a significant impact in the ESLCD trend (p < 0.001). ESLCD was associated with female, white, insurance, and household incomes above median. Medicare expansion was a significant factor for insured group, married patients and those from households under the median income level., Conclusion: Medicare approval for CT screening was found to have a statistically significant effect on the diagnosis of early-stage lung cancer and neither NLST-September-2011 nor CT-AP-2015-February-2015 impacted the incidence nor mortality rates., Policy Summary: To improve early-stage lung cancer diagnosis, it is vital to invest in health policies to increase Lung Cancer Screening implementation and to reduce disparities in access to diagnosis. Furthermore, policies that facilitate access to diagnosis and treatment are crucial to reduce lung cancer mortality., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Aim: In Cambodia, the Japan Society of Obstetrics and Gynecology and the Cambodian Society of Gynecology and Obstetrics have an on-going project, started in 2015, for cervical cancer prevention and treatment. The project, currently aimed at factory workers, includes a women's health education program that leads into cervical cancer prevention by establishment of a system for early detection and treatment. It begins by health education, screening for human papillomavirus (HPV), followed by colposcopy and quicker treatment of earlier precursor lesions., Methods: Rates for participant screening, HPV test positivity, cervical intraepithelial neoplasia (CIN) detection and distribution of HPV types were compared between two screening programs, factory-based and hospital-based. Some HPV test samples were divided into two, one of which was sent to Japan for a quality-control check of the Cambodian testing., Results: The factory-based participant screening rate was 19% (128/681). HPV was detected more frequently in the factory-based program participants (12%) than in the hospital-based program participants (5%). Unfortunately, however, the rate of receiving proper secondary colposcopy screening among the HPV-positive females was significantly higher in the hospital-based program (94%) than the factory-based program (40%) (P < 0.001). The Cambodian laboratory HPV testing accuracy was 92.6%. HPV types demonstrated no significant difference between the two prevention programs., Conclusion: We could successfully introduce HPV-based screening, starting from health education. However, low rate of screening, especially secondary screening for HPV positive factory workers was identified. Also, HPV testing could be further improved for accuracy through close monitoring., (© 2019 The Authors.

• Second lung cancer incidence is rising rapidly in females. • Second lung cancer incidence in females greatly exceeds all other second cancers. • Prolonged lung cancer surveillance after the definitive surgical resection is needed. • Surgery for early-stage, second lung cancers yields similar OS and LCSS as primary resection. The Lung Cancer Screening Trial demonstrated improved overall survival (OS) and lung cancer specific survival (LCSS), likely due to finding early-stage NSCLC. The purpose of our investigation is to evaluate whether long-term surveillance strategies (4+ years after surgical resection of the initial lung cancer(1LC)) would be beneficial in NSCLC patients by assessing the rates of second lung cancers(2LC) and the OS/LCSS in patients undergoing definitive surgery in 1LC as compared to 2LC (>48 months after 1LC) populations. SEER13/18 database was reviewed for patients during 1998–2013. Log-rank tests were used to determine the OS/LCSS differences between the 1LC and 2LC in the entire surgical group(EG) and in those having an early-stage resectable tumors (ESR, tumors <4 cm, node negative). Joinpoint analysis was used to determine rates of second cancers 4−10 year after 1LC using SEER-9 during years 1985–2014. The rate of 2LCs was significantly less than all other second cancers until 2001 when the incidence of 2LCs increased sharply and became significantly greater than all other second cancers in females starting in year 2005 and in men starting in year 2010. OS/LCSS, adjusted for propensity score by using inverse probability weighting, demonstrated similar OS, but worse LCSS for 2LCs in the EG, but similar OS/LCSSs in the ESR group. Because the rate of 2LCs are increasing and because the OS/LCSS of the 1LC and 2LC are similar in early-stage lesions, we feel that continued surveillance of patients in order to find early-stage disease may be beneficial.
