Ether and alkyl phospholipid compounds for treating cancer and imaging and detection of cancer
Methods and compositions utilizing ether and alkyl phospholipid ether analog compounds for treating cancer and imaging, monitoring, and detecting cancer stem cells in humans.
1. A method of treating cancer comprising administering to a patient in need thereof a therapeutically effective amount of 18-(p-iodophenyl)octadecyl phosphocholine) radiolabeled with 131 I or 125 I in combination with external beam radiation therapy, wherein the cancer comprises cancer stem cells and the number of cancer stem cells is reduced.
2. The method of claim 1 , wherein the cancer is selected from the group consisting of glioma, lung cancer, squamous cell carcinoma, renal cancer, melanoma, colorectal cancer, ovarian cancer, prostate cancer, breast cancer, and pancreatic cancer.
3. The method of claim 1 , wherein the isotope of iodine is 131 I.
4. The method of claim 1 , wherein the isotope of iodine is 125 I.
5. The method of claim 1 , wherein the method further comprises another cancer therapy selected from the group consisting of chemotherapy, tumor resection, abalative therapy, and local physical treatment on the basis of cold (cryo), heat (thermal), radiofrequency, and microwave.
6. The method of claim 1 , wherein the method of treatment enhances the radiosensitivity of the cancer.
