Tumor hypoxia is a well-known factor negatively influencing outcome in many solid tumors, including small cell lung cancer. Hypoxic cells are more radio-resistant, more chemo-resistant and more prone to develop distant metastases than normoxic cells.
One of the mechanisms responsible for survival of these therapy-resistant hypoxic cells is (macro-)autophagy: a phenomenon in which cells provide themselves with energy (ATP) by digesting their own cell-organelles. Chloroquine is a potent blocker of autophagy and has been demonstrated in a lab setting to dramatically enhance tumor response to radiotherapy, chemotherapy and even anti-hormonal therapy.
Thus, chloroquine might very well be able to increase overall survival in small cell lung cancer by sensitizing cells resistant to chemotherapy and radiotherapy.
