EACS 2011: Incidence of Non-AIDS Malignancies Stabilizes in D:A:D Study, but Prognosis Improves


Occurrence of non-AIDS-defining cancer has remained stable in recent years, according to an analysis of the large D:A:D observational cohort presented at the 13th European AIDS Conference (EACS 2011) last week in Belgrade. Prognosis for HIV positive people with such malignancies remains poor, but appears to have improved somewhat over time.

D:A:D investigators looked at trends over time in the incidence of non-AIDS-defining malignancies -- that is, all cancers except Kaposi sarcoma, non-Hodgkin lymphoma, and invasive cervical cancer -- and their survival outcomes. They prospectively collected information about the types and sites of all new non-AIDS cancers reported between January 2004 and January 2010.

Incidence rates were calculated for non-AIDS cancer overall and separately for lung cancer, anal cancer, and Hodgkin lymphoma.



o      1 year: 28%;

o      3 years: 42%;

o      5 years: 48%.

o      Lung cancer: 57%;

o      Hodgkin lymphoma: 22%.

o      Anal cancer: 16%.

Based on these findings, the D:A:D investigators concluded, "The incidence of [non-AIDS-defining malignancies] overall and for Hodgkin lymphoma and for lung and anal cancer has remained relatively stable from 2004-2010."

"The prognosis after a diagnosis of [non-AIDS-defining malignancies] is poor but has improved somewhat over time," they added. "Improvement in earlier diagnosis and better management of [non-AIDS-defining malignancies] is warranted."
