Abstract

In this study, we aimed to investigate changing epidemiologic features and distribution of histopathology of lung cancer within a 6-year period. We determined the cases diagnosed as primary lung cancer in our center in 1992, 1995, and 1998. The Şles of cases were retrospectively analyzed. The number of cases with lung cancer was 960 in 1992, 1184 in 1995, and 1287 in 1998. The ratio of female to male patients was 1:13.8 in 1992, 1:11.5 in 1995 and 1:10.9 in 1998. Although there was an increase in ratio of female patients, this was not statistically significant. There was not a significant change in number of cases below 40 years of age whereas there was an evident increase in the number of cases over 60 years of age (p<0.0005). The mean age was 56.4±9.4 in 1992 and 57.9±10.2 in 1998 (p=0.056). While proportion of cases with squamous cell carcinoma decreased from 60.6% in 1992 to 49.7% in 1998, the proportion of cases with adenocarcinoma increased from 13.5% in 1992 to 30.9% in 1998 (p<0.0001). As a result , our study involving a time period of 6 years showed that there were changes in some epidemiologic features like histopathologic distribution, female to male ratio and age distribution of cases with lung cancer with elapsing time.

Özet

Bu çalışmada, akciğer kanserli olgularda, 6 yıllık bir süre içinde tümör tipi dağılımı ve epidemiyolojik özel liklerde meydana gelen değişiklikleri araştırmayı amaçladık. Merkezimizde 1992, 1995 ve 1998 yıllarında primer akciğer kanseri tanısı alan olgular saptandı. Olguların dosyaları geriye dönük olarak incelendi. Akciğer kanserli olgu sayısı 1992 yılında 960, 1995 yılında 1184 ve 1998 yılında 1287 idi. Kadın-erkek hasta oranı 1992'de 1:13.8, 1995'te 1:11.5 ve 1998'de 1:10.9 olarak bulundu. Kadın hasta oranında artış eğilimi olmakla birlikte, bu artış istatistiksel olarak anlamlı değildi. Kırk yaş altı olgu sayısında anlamlı bir değişiklik saptanmazken, 60 yaş üzeri olgu sayısında belirgin bir artış olduğu bulundu (p<0.0005). Yaş ortalaması 1992 yılında 56.4±9.4 yıl, 1998 yılında 57.9±10.2 yıl idi (p=0.056). 1992 yılında %60.6 olan epidermoid karsinom oranı 1998 yılında %49.7'ye düşerken, adenokanserli olguların oranının %13.5'ten %30.9'a yükseldiği saptandı (p<0.0001). Sonuç olarak, çalışmamız 6 yıllık bir süreyi kapsamakla birlikte, ilerleyen yıllarla birlikte akciğer kanserli olguların tümör tipi dağılımı, kadın-erkek hasta oranları ve yaş dağılımı gibi bazı epidemiyolojik özelliklerinde değişiklikler meydana geldiğini göstermektedir.
