Association Between XRCC1 and WRN as Genetic Markers of Stability and Susceptibility to Cancer in Patients with HIV/AIDS and Cancer: a Cross-Sectional Study.

Background: HIV-induced immunodeficiency has been implicated as a key factor for risk of cancer. Neoplasia is considered to result from accumulation of damage to the genome. Polymorphisms in repair genes, such as the XRCC1 and WRN, have been associated with susceptibility to development of cancer in patients with HIV/AIDS.

Acute myeloid leukemia of donor origin after allogeneic stem cell transplantation from a sibling who harbors germline XPD and XRCC3 homozygous polymorphisms.

A 54-year-old woman was diagnosed with infiltrative ductal breast carcinoma. Two years after treatment, the patient developed an acute myeloid leukemia (AML) which harbored del(11q23) in 8% of the blast cells. The patient was submitted for allogeneic stem cell transplantation (aSCT) from her HLA-compatible sister.
