Prophylaxis of malaria in geographic areas without resistance to chloroquine The mechanism through which chloroquine is acting on cancer cells has mainly been attributed to the inhibition of autophagy as a consequence of its lysosomotropic properties (13, 24). These tumors also display treatment non-compliance and responses to standard therapy are invariably transient; consequently, the prognosis barely exceeds 14 months and recurrence is inevitable addition of chloroquine can improve clinical outcomes.
