Abstract
OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic has affected the utilization of healthcare services, including participation in cancer screening programs. We compared cancer screening participation rates for colorectal, gastric, breast, and cervical cancers among participants in the National Cancer Screening Program (NCSP) in 2019 and 2020 to address the potential distraction effect of COVID-19 on cancer screening.
METHODS
Data from the NCSP for 4 cancer types (stomach, colorectal, breast, and cervical) in 2019 and 2020 were used to calculate cancer screening participation rates by calendar month, gender, age group, and geographical region. Monthly participation rates were analyzed per 1,000 eligible individuals.
RESULTS
The screening participation rate decreased in 2020 compared to 2019 for all 4 cancers: colorectal (40.5 vs. 35.3%), gastric (61.9 vs. 54.6%), breast (63.8 vs. 55.8%), and cervical (57.8 vs. 52.2%) cancers. Following 2 major COVID-19 waves in March and December 2020, the participation rates in the 4 types of cancer screening dropped compared with those in 2019. The highest decline was observed in the elderly population aged 80 years and older (percentage change: -21% for colorectal cancer; -20% for gastric cancer; -26% for breast cancer; -20% for cervical cancer).
CONCLUSIONS
After the 2 major COVID-19 waves, the screening participation rate for 4 types of cancer declined compared with 2019. Further studies are needed to identify the indirect effects of the COVID-19 pandemic on cancer patients, such as delayed diagnoses of cancer or excess cancer deaths.

Summary
Korean summary
본 연구는 코로나 대유행 기간 전과 후 대장암, 위암, 유방암, 자궁경부암 검진 수검률 차이를 비교하고자 하였다. 첫 코로나 확진자가 발생한 2020년을 코로나 대유행 기간, 전년도 기간인 2019년을 코로나 대유행 전 기간으로 설정하며 국민건강보험공단에서 집계된 전수자료를 이용하여 암 검진 대상자 수와 수검자 수를 비교 분석하였다. 4개 암종 모두에서 2019년도와 비교하여 2020년도에 전국적으로 수검률이 감소하는 경향이 있었으며, 1차 대유행이 있었던 3월과 3차 대유행 시기인 12월에 2019년도 동기간과 비교하여 수검률이 크게 감소하였고, 80대 이상 노인 인구에서 감소폭이 다른 연령대와 비교하여 크게 나타났다.

Abstract
OBJECTIVES
Cancer is a multi-factorial disease, with various intrinsic and environmental factors contributing to its occurrence. Human papillomavirus (HPV) has been associated with the occurrence of many cancers. India severely suffers from 3 HPV-associated cancers (cervical cancer, oral cancer, and oropharyngeal cancer). Hence, the present study aimed to evaluate the HPV burden in these 3 cancers among patients from the western region of India.
METHODS
DNA was isolated from samples from 400 cervical cancer, 127 oral cancer, and 75 oropharyngeal cancer patients. Polymerase chain reaction was performed using degenerate primers for HPV infection.
RESULTS
Overall, HPV infection was observed in 87% of cervical cancer cases, 12.5% of oral cancer cases, and 26.7% of oropharyngeal cancer cases when analyzed with a cumulative detection method using the MY 09/11, GP 5+/6+, and CP I/II primer sets.
CONCLUSIONS
A significant prevalence of HPV infection was detected in all 3 cancers using the degenerate primer sets. This finding implies that testing for HPV infection using multiple primer sets is crucial for determining its actual prevalence in various malignancies.

Summary
Key Message
The study emphasised the need to screen population of India for HPV infection for better prognosis and disease management and showcases a perfect screening module to efficiently screen the HPV strains.

Abstract
Cervical cancer is a well-known preventable cancer worldwide. Many countries including Korea have pursued the positive endpoint of a reduction in mortality from cervical cancer. Our aim is to examine changing trends in cervical cancer incidence and mortality after the implementation of a national preventive effort in Korea. Cervical cancer incidence data from 1999 to 2011 and mortality data from 1983 to 2013 were collected from the Korean Statistical Information Service. Yearly age-standardized rates (ASR) per 100,000 were compared using two standards: the 2005 Korean population and the world standard population, based on Segi’s world standard for incidence and the World Health Organization for mortality. In Korea, the age-standardized incidence of cervical cancer per 100,000 persons declined from 17.2 in 2000 to 11.8 in 2011. However, the group aged 25 to 29 showed a higher rate in 2011 (ASR, 6.5) than in 2000 (ASR, 3.6). The age-standardized mortality rate per 100,000 persons dropped from 2.81 in 2000 to 1.95 in 2013. In the worldwide comparison, the incidence rates remained close to the average incidence estimate of more developed regions (ASR, 9.9). The decreasing mortality trend in Korea approached the lower rate observed in Australia (ASR, 1.4) in 2010. Although the incidence rate of cervical cancer is continuously declining in Korea, it is still high relative to other countries. Moreover, incidence and mortality rates in females aged 30 years or under have recently increased. It is necessary to develop effective policy to reduce both incidence and mortality, particularly in younger age groups.

한국의 자궁경부암 발생률과 사망률은 꾸준히 감소하고 있는 추세이다. 그러나 한국의 발생률은 여러 선진국에 비해 여전히 높은 수준에 머무르고 있다. 또한, 지난 10년 동안 자궁경부암 사망률은 상대적으로 큰 감소를 보이지 않았다. 특히 35세 미만에서는 자궁경부암 발생률이 감소하지 않았고, 사망률은 오히려 높아진 것으로 나타났다. 젊은 연령층의 자궁경부암 예방과 관리가 필요하다.
