Background:
The advent of highly active antiretroviral therapy (HAART) in 1996 led to a decrease in
the incidence of Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), but not of
other cancers, among people with HIV or AIDS (PWHA). It also led to marked increases in
their life expectancy.
Methods:
We conducted a record-linkage study between the Swiss HIV Cohort Study and nine Swiss
cantonal cancer registries. In total, 9429 PWHA provided 20 615, 17 690,
and 15 410 person-years in the pre-, early-, and late-HAART periods,
respectively. Standardised incidence ratios in PWHA vs the general
population, as well as age-standardised, and age-specific incidence rates were computed
for different periods.
Results:
Incidence of KS and NHL decreased by several fold between the pre- and early-HAART
periods, and additionally declined from the early- to the late-HAART period. Incidence
of cancers of the anus, liver, non-melanomatous skin, and Hodgkin's lymphoma increased
in the early- compared with the pre-HAART period, but not during the late-HAART period.
The incidence of all non-AIDS-defining cancers (NADCs) combined was similar in all
periods, and approximately double that in the general population.
Conclusions:
Increases in the incidence of selected NADCs after the introduction of HAART were
largely accounted for by the ageing of PWHA.
Background Rare cancers here defined as those with an annual incidence rate less than 6/100,000 in Europe, pose challenges for diagnosis, treatments, and clinical decision-making. Information on rare cancers is scant. We updated the estimates of the burden of rare cancers in Europe, their time trends in incidence and survival, and provide information on centralization of treatments in seven European countries. Methods We analysed data on more than two million rare cancer diagnoses, provided by 83 cancer registries, to estimate European incidence and survival in 2000-2007 and the corresponding time trends during 1995-2007. Incidence rates were calculated as the number of new cases divided by the corresponding total person years in the population. Five-year relative survival (RS) was calculated by the Ederer-2 method.

In the last 20 years, expenditures on pharmaceuticals - as well as total health expenditures - have grown faster than the gross national product in all European countries. The aim of this paper was to review policies that European governments apply to reduce or at least slow down public expenditure on pharmaceutical products. Such policies can target the industry, the wholesalers and retailers, prescribers, and patients. The objectives of pharmaceutical policies are multidimensional and must take into account issues relating to public health, public expenditure and industrial incentives. Both price levels and consumption patterns determine the level of total drug expenditure in a particular country, and both factors vary greatly across countries. Licensing and pricing policies intend to influence the supply side. Three types of pricing policies can be recognised: product price control, reference pricing and profit control. Profit control is mainly used in the UK. Reference pricing systems were first used in Germany and The Netherlands and are being considered in other countries. Product price control is still the most common method for establishing the price of drugs. For the aim of fiscal consolidation, price-freeze and price-cut measures have been frequently used in the 1980s and 1990s. They have affected all types of schemes. For drug wholesalers and retailers, most governments have defined profit margins. The differences in price levels as well as the introduction of a Single European Pharmaceutical Market has led to the phenomenon of parallel imports among member countries of the European Union. This may be facilitated by larger and more powerful wholesalers and the vertical integration between wholesalers and retailers. To control costs, the use of generic drugs is encouraged in most countries, but only few countries allow pharmacists to substitute generic drugs for proprietary brands. Various interventions are used to reduce the patients' demand for drugs by either denying or limiting reimbursement of products and providing an incentive for patients to reduce their consumption of drugs. These interventions include defining a list either of drugs reimbursed (positive list) or one of drugs not reimbursed (negative list), and patient co-payments, which require patients to pay a proportion of the cost of a prescribed product or a fixed charge. Policies intended to affect physicians' prescribing behaviour include guidelines, information (about price and less expensive alternatives) and feedback, and the use of budgetary restrictions.
Although persons infected with human immunodeficiency virus (HIV), particularly men who have sex with men, are at excess risk for anal cancer, it has been difficult to disentangle the influences of anal exposure to human papillomavirus (HPV) infection, immunodeficiency, and combined antiretroviral therapy. A case-control study that included 59 anal cancer cases and 295 individually matched controls was nested in the Swiss HIV Cohort Study (1988-2011). In a subset of 41 cases and 114 controls, HPV antibodies were tested. A majority of anal cancer cases (73%) were men who have sex with men. Current smoking was significantly associated with anal cancer (odds ratio (OR) = 2.59, 95% confidence interval (CI): 1.25, 5.34), as were antibodies against L1 (OR = 4.52, 95% CI: 2.00, 10.20) and E6 (OR = ∞, 95% CI: 4.64, ∞) of HPV16, as well as low CD4+ cell counts, whether measured at nadir (OR per 100-cell/μL decrease = 1.53, 95% CI: 1.18, 2.00) or at cancer diagnosis (OR per 100-cell/μL decrease = 1.24, 95% CI: 1.08, 1.42). However, the influence of CD4+ cell counts appeared to be strongest 6-7 years prior to anal cancer diagnosis (OR for <200 vs. ≥500 cells/μL = 14.0, 95% CI: 3.85, 50.9). Smoking cessation and avoidance of even moderate levels of immunosuppression appear to be important in reducing long-term anal cancer risks.
Hodgkin lymphoma (HL) risk is elevated among persons infected with HIV (PHIV)and has been suggested to have increased in the era of combined antiretroviral therapy (cART). Among 14 606 PHIV followed more than 20 years in the Swiss HIV Cohort Study (SHCS), determinants of HL were investigated using 2 different approaches, namely, a cohort and nested case-control study, estimating hazard ratios (HRs) and matched odds ratios, re-
SM survival is high and still increasing in European patients. The gap between Northern and Southern and especially Eastern European countries, although still present, diminished over time. Differences in stage distribution at diagnosis may explain most of the geographical differences. However, part of the improvement in survival may be attributed to overdiagnosis from early diagnosis practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
