7 . The method of claim 2 , wherein the cancer is colorectal cancer, stomach cancer, pancreatic cancer, breast cancer, kidney cancer, lung cancer-non small cell, glioblastoma, or cervical cancer and the chemotherapy agent is fluorouracil, bevacizumab, irinotecan hydrochloride, capecitabine, cetuximab, oxaliplatin, leucovorin calcium, panitumumab, regorafenib, or ziv-aflibercept.
8 . The method of claim 2 , wherein the cancer is bladder cancer, Kaposi's sarcoma, ovarian cancer, breast cancer, cervical cancer, head and neck cancer, esophageal cancer, lung cancer, mesothelioma, kidney cancer, pancreatic cancer, or brain/CNS tumors and the chemotherapy agent is cyclophosphamide, doxorubicin hydrochloride, cisplatin, gemcitabine, or a combination of gemcitabine and cisplatin.
9 . The method of claim 8 , wherein the bladder cancer is metastatic and the chemotherapy agent is cyclophosphamide.
10 . The method of claim 9 , wherein the cyclophosphamide is administered at a daily dose of 0.3 mg/kg to 2.5 mg/kg and the composition provides a daily dose of 2 g of the quercetin.
11 . The method of claim 10 , wherein the quercetin is in the form of isoquercetin or isoquercitrin.
12 . The method of claim 8 , wherein the bladder cancer is metastatic and the chemotherapy agent is doxorubicin.
13 . The method of claim 2 , wherein the cancer is kidney cancer, leukemia, bladder cancer, pancreatic cancer, breast cancer, brain/CNS tumor, melanoma, colorectal cancer, lung cancer, glioblastoma, cervical cancer, ovarian cancer, gastrointestinal stromal tumor, or renal cell carcinoma and the chemotherapy agent is cyclophosphamide, everolimus, aldesleukin, bevacizumab, axitinib, sorafenib tosylate, pazopanib hydrochloride, sunitinib, or temsirolimus.
14 . The method of claim 13 , wherein the kidney cancer is metastatic and the chemotherapy agent is sunitinib.
15 . The method of claim 14 , wherein the effective amount is an amount that provides 5 mg to 25 mg sunitinib per day and the composition provides a daily dose of 250 mg to 5 g of the quercetin.
16 . The method of claim 1 , wherein the quercetin is selected from the group consisting of quercetin aglycone, isoquercetin, and isoquercitrin.
17 . The method of claim 16 , wherein the composition includes folic acid.
18 . The method of claim 1 , wherein the quercetin is selected from the group consisting of quercetin aglycone, isoquercetin, and isoquercitrin.
19 . The method of claim 18 , wherein the composition includes folic acid.
20 . The method of claim 19 , wherein the quercetin is in the form of isoquercetin or isoquercitrin.
