Tumor-associated human carbonic anhydrases (hCAs), particularly isoforms hCA IX and hCA XII, are overexpressed in hypoxic regions of solid tumors and play a crucial role in regulating pH homeostasis, promoting cancer cell survival and enhancing invasiveness. These enzymes have emerged as promising therapeutic targets in cancer treatment, including photothermal therapy (PTT). PTT is a minimally invasive technique that uses light-absorbing agents to convert near-infrared (NIR) light into heat, effectively inducing localized hyperthermia and promoting cancer cell apoptosis. Recent advances in the design of hCA-targeted photothermal agents have shown promise in selectively targeting and ablating cancer cells while sparing healthy tissues. We explore here recent advancements in developing combination therapies that integrate hCA-targeted strategies with PTT for tumor treatment. By focusing on tumor-associated isoforms hCA IX and hCA XII, we underscore the potential of hCA inhibition to enhance both the efficacy and specificity of PTT in cancer therapy. We also address critical challenges and outline future directions, emphasizing the need to improve the biocompatibility, stability, and clinical translation of hCA-targeted photothermal agents. This mini review highlights the promise of combining hCA inhibition with PTT as an innovative therapeutic approach, aiming to advance more precise and effective cancer treatments.
