Background  ↓ ADCs with ART.  NADCs now represent a much larger fraction of the overall cancers in HIV-infected patients.  We observed a change in immune status at the moment of cancer diagnosis over the years in our HIV-infected population. Methods  Retrospective study.  Medical charts review of HIV-infected patients diagnosed with cancer from  Type of cancer, history of ART, CD4 cell count, viral load at cancer diagnosis recorded.  95 patients, 108 cancers.

Conclusion  Cancer seems no longer a pre-morbid condition in HIV-infected patients that could eventually benefit the same anticancer treatment than the general population.  Nevertheless, cancer remains an important cause of morbidity and mortality in HIV-infected patients.  Importance of Active screening for HIV in population at risk. Primary prevention of cancer risk factors. Antiretroviral therapy use. Screening HIV-infected patients for cancer in agreement with established guidelines. A multidisciplinary team approach.
