title: [High incidence of non-AIDS-defined cancers among HIV-infected patients in Germany. A 3-year nationwide review].
abstract: OBJECTIVE
  It was the main aim of this study to obtain data on the epidemiology of AIDS- and not AIDS-defined malignancies in HIV-positive persons, the results to provide an epidemiological overview and to be the basis for further research initiatives. Additionally it sought to gain an impression of the realities of treatment of patients with HIV-associated malignant tumors in Germany.
  
  
  METHODS
  Over a period of 3 years (from the beginning of 2000 to the end of 2002) data were retrospectively collected on the incidence of malignant tumors in HIV-positive patients. A questionnaire was sent to all members of the German Working Party of Physicians in Private Practice Treating HIV-Infected Patients, all members of the Association of Haematologists and Oncologists in Private Practice, and all out-patient HIV clinics in Germany. The questionnaires were sent to a total of 949 practices/clinics. The data were collected on all AIDS- and not-AIDS-defined haematological malignancies and all AIDS- and not-AIDS-defined solid malignant tumors in HIV-positive patients, as well as on time of diagnosis of the malignancy, tumor stage, tumor treatment and response to treatment.
  
  
  RESULTS
  380 data sets on 376 patients of 50 practices/clinics were included in the analysis (four patients had two malignant tumors). 180 malignant neoplasms (47%) were AIDS-defined: 89 Kaposi's sarcomas, 82 aggressive B-cell lymphomas and 9 invasive cervical carcinomas. The aggressive B-cell lymphomas consisted of 19 cases of Burkitt's lymphoma, 8 of Castleman's disease and 12 of primary cerebral malignant lymphoma. Of the 200 (52.6%) not-AIDS-defined malignant tumors 133 were 133 solid tumors, 40 of them anal carcinoma (20% of all not-AIDS-defined malignancies) and 67 haematological malignancies, 22 of these Hodgkin's lymphoma (11.0% of all not-AIDS-defined malignancies). The incidence of anal carcinoma is estimated to be 34 (95% CI 24-470) per 100 000 patient-years, that of Hodgkin's lymphoma 19 (95% CI 12-28) per 100 000 patient-years.
  
  
  CONCLUSIONS
  This study indicates that over a period of 3 years there was a very high incidence of not-AIDS-defined malignancies. Of special note is the high incidence of anal carcinoma and Hodgkin's lymphoma, compared with their incidence among the entire German population.
