OBJECTIVES: To compare long-term outcomes of laryngeal cancer (LC) in people living with HIV (PLWH) versus uninfected individuals and determine how clinical and viral factors-such as demographics, cancer stage, HIV viral load, and CD4 nadir-contribute to these outcomes.
METHODS: This was a retrospective case-control study of 749 patients seen for LC at a single tertiary care center between 2003 and 2017. Of these, 22 had HIV at the time of LC diagnosis, and they were matched in a 1:4 ratio to uninfected controls based on sex, presence of smoking history, and age at cancer diagnosis. Kaplan-Meier survival curves and Cox proportional hazards models were constructed to identify overall and disease-free survival differences based on HIV status, as well as other clinical and viral factors.
RESULTS: Compared to all uninfected individuals, PLWH were diagnosed with LC approximately 6 years younger (p = .013). 1-, 2-, and 5-year overall survival for PLWH were 86.4% (63.4%-95.4%), 77.3% (53.7%-89.9%), and 65.8% (40.8%-82.2%), respectively following LC diagnosis, and HIV was not significantly associated with overall (HR = 3.34 [0.59-18.79]) or disease-free survival (HR = 2.12 [0.71-6.36]). The incidence rate of locoregional recurrence among PLWH was 541 compared to 371 per 10,000 person-years in controls, which were not significantly different (p = .420). Furthermore, among PLWH, peak viral load and CD4 nadir were not associated with overall or disease-free survival.
CONCLUSION: While previous work has shown that HIV is associated with elevated risk of LC, survival did not differ significantly between PLWH and uninfected individuals in this study.
LEVEL OF EVIDENCE: 3.
