title: Liposomal anthracycline chemotherapy and the risk of second malignancies in patients with Kaposi's sarcoma (KS).
abstract: OBJECTIVE
  People living with HIV (PLWH) are at increased risk of cancer, both non-AIDS- and AIDS-defining malignancies (NADM and ADM). Systemic chemotherapy also predisposes to secondary cancers. The potential contribution of systemic liposomal anthracycline chemotherapy (SLAC) to the development of second cancers in PLWH is unknown.
  
  
  METHODS
  Since 1998, we have treated 495 PLWH and Kaposi's sarcoma (KS) with a stage-stratified approach including 163 who received SLAC as first-line treatment for KS. Subsequent ADM and NADM diagnosed in this population were recorded.
  
  
  RESULTS
  More patients who received SLAC had T1 stage disease (p < 0.0001) and lower CD4 cell counts (p < 0.0001) in line with the stage-stratified treatment, but there were no significant differences in age (p = 0.29), gender (p = 0.18), prior AIDS-defining illness (p = 0.45), plasma HIV viral load (p = 0.15), or HHV8 viral load (p = 0.39) between the two groups. During a median follow-up of 4.6 years (maximum 15 years) from KS diagnosis, 28 patients developed a second cancer (5 ADM and 23 NADM). The 5-year cumulative risk of second cancer is 5.8 % (95 % CI 3.0-8.6 %), and there is no significant difference in the rate between those treated with SLAC and those not (log rank p = 0.19). Most patients (n = 131) were treated with daunoxome (liposomal daunorubicin) chemotherapy, and there was no significant correlation between risk of second cancer and cumulative dose of daunoxome (p = 0.23).
  
  
  CONCLUSIONS
  Although the risk of second cancer after a diagnosis of KS in PLWH is high, systemic liposomal anthracycline chemotherapy does not appear to increase the risk.
