Despite its clinical promise, photodynamic therapy (PDT) suffers from a key drawback associated with its oxygen‐dependent nature, which limits its effective use against hypoxic tumors. Moreover, both PDT‐mediated oxygen consumption and microvascular damage further increase tumor hypoxia and, thus, impede therapeutic outcomes. In recent years, numerous investigations have focused on strategies for overcoming this drawback of PDT. These efforts, which are summarized in this review, have produced many innovative methods to avoid the limits of PDT associated with hypoxia. PDT beats hypoxia: Novel and robust strategies, which can improve the therapeutic efficacy of photodynamic therapy (PDT) for hypoxic tumors, have been widely investigated in recent years. These efforts have led to the development of new approaches that have changed the paradigm of PDT and provided solutions to some key problems.
