Th1/Th2 balance: the hypothesis, its limitations, and implications for health and disease. Kidd P. Altern Med Rev. 2003 Aug;8(3):223-46. Review. PMID: 12946237 Th1 pathways typically produce activation of cytotoxic T lymphocytes (Tc), NK cells, macrophages, and monocytes, all of which can attack cancer cells and generally defend against tumors. 55 IFN-gamma and other Th1 cytokines are typically lower in advanced cancer patients, while the Th2 marker IL-4 can be higher or unchanged.56 Nodules of non-small cell lung cancer freshly removed from patients expressed a marked imbalance toward Th2, as did biopsy samples from basal cell carcinoma.57 In prostate cancer patients IL-2 was low (Th1) and IL-10 high.58 IL-10 is a confirmed Th1-suppressive cytokine, and heightened IL-10 is a common factor in cancer.55 IL-10 has a variety of suppressive effects that include inhibiting Th1 cytokine production, down-regulating APC and NK cell function, and lowering overall T-cell proliferation.57 Especially under the influence of IL-4 (Th2), tumor cells apparently up-regulate IL-10 that suppresses nearby killer cells. Tumor-derived IL-10 has been documented in lymphoma, ovarian carcinoma, melanoma, neuroblastoma, and renal cell and colon carcinoma.57 IL-12 is another cytokine that can be up-regulated by Th1 activity and inhibited by Th2.59 A low IL-12/IL-10 ratio was found in cervical cancer patients.55 Recent clinical studies suggest elevated IL-10 is predictive of a poor prognosis. 57 With both IL-4 and IL-10 being proven inhibitors of Th1 and promoters of Th2 activity, the recognized capability of cancerous tissue to suppress immunity is readily rationalized.

Dietary omega-3 polyunsaturated fatty acids plus vitamin E restore immunodeficiency and prolong survival for severely ill patients with generalized malignancy: a randomized control trial. Gogos CA, Ginopoulos P, Salsa B, Apostolidou E, Zoumbos NC, Kalfarentzos F. Cancer. 1998 Jan 15;82(2):395-402. PMID: 9445198 DOI: 10.1002/(SICI)1097-0142(19980115)82:23.0.CO;2-1 Dietary supplementation with omega-3 PUFA (18 g/day) restored both the Th/Ts cell ratio and TNF production by endotoxin-stimulated PBMC. Our finding is not in accordance with former reports that long term consumption of omega-3 PUFA decreases T cell mitogenic response, DTH, and the percentage of T-helper cells,[28] and this may be the result of the parallel antioxidant effect of vit E. Most significantly, omega-3 PUFA increased the survival of all our patients, ...

Annual intramuscular injection of a megadose of cholecalciferol for treatment of vitamin D deficiency: efficacy and safety data. Diamond TH, Ho KW, Rohl PG, Meerkin M. Med J Aust. 2005 Jul 4;183(1):10-2. PMID: 15992330 Conclusions: Once-yearly intramuscular cholecalciferol injection (600 000 IU) is effective therapy for vitamin D deficiency. While this therapy appears to be safe, the potential for developing hypercalciuria needs to be examined in a large randomised controlled trial.
