The prevalence, incidence and natural history of anal cellular abnormalities in mature-aged homosexual men

肛门癌是男同性恋者最常见的癌症之一，在澳大利亚，在对妇女进行常规宫颈检查之前，肛门癌的发病率高于宫颈癌的发病率。成熟的老年男同性恋男性肛门健康研究将招募1000名45岁以上的男性，并对他们进行长达5年的随访，以调查男性肛门癌前病变的进展以及筛查计划的潜力，以早期发现这些病变。

Anal cancer is one of the most common cancers in homosexual men and rates in Australia are now higher than those of cervical cancer prior to the introduction of routine cervical screening in women. The Mature Aged Gay MenÍs Anal Health Study will enrol 1000 men over 45 years old and follow them for up to 5 years to investigate the progression of anal pre-cancerous lesions in men and the potential of a screening program to allow early detection of these lesions.
