Abstract
En 中文
Immune checkpoint inhibitors (ICIs) are a standard treatment for advanced non-small-cell lung cancer (NSCLC), but limited data exist regarding their use in patients with HIV-positive. This study evaluated the efficacy and safety of ICI-based therapy in this population. In this single-center, comparative study, 18 patients with treatment-naive advanced NSCLC with HIV (experimental group) and 40 HIV-negative controls (control group) received 4-6 cycles of tislelizumab plus platinum-based chemotherapy, followed by tislelizumab maintenance until disease progression or unacceptable toxicity. A higher incidence of tuberculosis was observed in the experimental group compared with the control group (33.3 vs. 20.0%). The objective response rate was 77.8% [95% confidence interval (CI): 56.5-99.1] in the experimental group and 77.5% (95% CI: 64-91) in the control group (P = 0.981). The 6-month progression-free survival rate was 83.3% (95% CI: 64.3-99.9) for the experimental group and 82.5% (95% CI: 70.2-94.8) for the control group (P = 0.227). The 6-month overall survival rate was 88.9% (95% CI: 72.8-99.9) in the experimental group and 97.5% (95% CI: 92.4-99.9) in the control group (P = 0.192). The incidences of grade 3 or higher adverse events were 38.9 and 32.5% in the experimental and control groups, respectively. One patient in the experimental group died due to a serious opportunistic infection. Immunotherapy combined with chemotherapy showed comparable efficacy and safety in patients with advanced NSCLC irrespective of HIV status. Patients with HIV-positive had a higher tendency for opportunistic infections, including tuberculosis.
