Abstract

This study compared breast cancer survival and the prognostic factors across different age groups of women in Penang, Malaysia. Data on 2,166 women with breast cancer who had been diagnosed between 2010 and 2014 were extracted from the Penang Breast Cancer Registry and stratified into 3 age groups: young (< 40 years old), middle-aged (40-59 years old), and elderly (≥ 60 years). The overall and relative survival rates were calculated using the life table method, median survival time was calculated using the Kaplan-Meier method, and comparisons between groups were conducted using the log-rank test. Prognostic factors were analyzed using a Cox proportional hazards model. The 5-year overall and breast cancer-specific survival rates for women with breast cancer in Penang were 72.9% and 75.2%, with a mean survival time of 92.5 months and 95.1 months, respectively. The 5-year breast cancer-specific survival rates for young, middle-aged, and elderly women were 74.9%, 77.8%, and 71.4%, respectively, with a mean survival time of 95.7 months, 97.5 months, and 91.2 months. There was a significant difference in breast cancer survival between age groups, with elderly women showing the lowest survival rate, followed by young and middle-aged women. Disease stage was the most prominent prognostic factor for all age groups. Survival rates and prognostic factors differed according to age group. Treatment planning for breast cancer patients should be age-specific to promote better cancer care and survival.

Summary

Key Message
The relationship between breast cancer survival and age at diagnosis has been explored, but information between survival at different age groups remains unclear, in addition to conflicting study results. This multicentre study was conducted to compare breast cancer survival across different age groups in an Asian setting.

Changing trends in the incidence (1999-2011) and mortality (1983-2013) of cervical cancer in the Republic of Korea: Yoon Park, Champadeng Vongdala, Jeongseon Kim, Moran Ki; Epidemiol Health. 2015;37:e2015024. Published online May 29, 2015; DOI: https://doi.org/10.4178/epih/e2015024

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.

Summary

Korean summary
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.
