{"title":"Annual disease burden due to human papillomavirus (HPV) 6 and 11 infections in Finland.","authors":"Kari J Syrjänen","doi":"10.1080/00365540902887730","DOIUrl":"https://doi.org/10.1080/00365540902887730","url":null,"abstract":"<p><p>In addition to cancer of the lower female genital tract, human papillomaviruses (HPV) are associated with a large number of benign, precancer and cancer lesions at different anatomic sites in both genders. Malignant tumours and their precursors are usually attributed to the oncogenic (high-risk, HR) HPV types, whereas benign lesions (papillomas) are associated with the low-risk (LR) HPV types, most notably with HPV6 and HPV11. Until recently, the main interest in HPV research has been focused on HR-HPV types and their associated pathology, and much less attention has been paid to the lesions caused by the LR-HPV types. With the recent licensing of an effective prophylactic vaccine against the 2 most important LR-HPV types (HPV6 and HPV11), it has become timely to make a systematic survey on the annual disease burden due to these 2 HPV genotypes in our country. These types of data should form the foundation for all calculations of the annual costs needed to treat these diseases by conventional means. Accurate estimates of disease burden are also mandatory for all modelling of the cost-effectiveness of prophylactic HPV6 and HPV11 vaccines. If proven useful for any of these purposes, this document will have fulfilled its purpose. In the first step, published HPV literature was used to create a list of benign, premalignant and malignant lesions associated with this virus at different anatomic sites. GLOBOCAN 2004 (IARC) database was used to derive the global numbers of incident cases for each of these malignancies in 2002, and the Finnish Cancer Registry (FCR) website for obtaining these (y 2005) numbers in Finland. The evidence linking HPV to each individual tumour category was classified as: 1) established, 2) emerging, and 3) controversial. All published evidence was weighted for each individual malignant, premalignant and benign lesion, anatomic region by region, while assessing the attributable fraction of HPV6/11 genotypes in each lesion. Because benign and most of the precancer lesions are not registered by FCR or GLOBOCAN, different approaches had to be used to derive the best estimates for their incidence, based on published literature or other registries (e.g. genital wart registry of the UK and Wales, and mass screening registry of FCR). With a lack of reasonable consensus, a lower and an upper limit was set for the range of estimates. In cases with different age-specific incidence (e.g. genital warts), the population pyramid of Finland was used to calculate the incident cases. Where well established, the different incidence rates among males and females were used to calculate the numbers of incident cases by gender. The malignant neoplasms with established or emerging evidence on the causal role of HPV are listed by their ICD-10 codes in Table I. Included in this list are also 2 controversial malignancies (colorectal cancer and endometrial cancer), of which the contradictory HPV data are critically discussed.

The recent licensing of an effective prophylactic vaccine against the 2 most important LR-HPV types (HPV6 and HPV11) has resulted in considerably increased interest in these LR-HPV types as well. This author recently conducted a systematic survey of the annual disease burden due to HPV6/11 infections in Finland. As a rational continuation, the present survey was conducted to estimate the annual disease burden due to HPV16 and HPV18 infections in our country. Together, these 2 documents form the foundation for calculations of the annual costs needed to treat the diseases caused by these 2 most common LR and HR HPV types. Similar to HPV6/11, accurate estimates of disease burden are also mandatory for all modelling of the cost-effectiveness of prophylactic HPV16/18 vaccines. In the first step, the published HPV literature was used to create a list of benign, premalignant and malignant lesions associated with this virus at different anatomic sites. The GLOBOCAN 2004 (IARC; International Agency for Research on Cancer) database was used to derive the global numbers of incident cases for each of these malignancies in 2002, and the Finnish Cancer Registry (FCR) website was used to obtain these numbers for Finland (y 2005). The evidence linking HPV to each individual tumour category was classified as: (1) established, (2) emerging, and (3) controversial.

Where well established, the different incidence rates among males and females were used to calculate the numbers of incident cases by gender. The present survey implicates that a minimum of 7859 to 8316 new cases of HPV16- or HPV18-associated clinical lesions would be detected each y in Finland, if all were registered. In other words, these numbers represent the annual disease burden due to these 2 most common HR-HPV genotypes.

A particular situation among HIV-infected individuals is the finding of a 'discordant' response, which means a virological failure with the maintenance of an optimal immune function. In these subjects, the mere determination of the genotypic pattern of drug resistance is not necessary.
