Definitions
- the present invention relates to methods and products for preventing cancer through topical application of cancer inhibitors. More particularly, it relates to the use of sunscreens and after sun lotions and creams containing vitamin D 3 , vitamin D derivatives (natural or synthetic), or cod-liver oil to inhibit skin cancers and other dermatological disorders related to ultraviolet light exposure.
- Non- melanoma basic and squamous cell carcinoma
- sunscreens may reduce the incidence of nonmelanoma cancer.
- Sunscreens seek to block the ultraviolet light, which causes sunburn and is a probable cause of skin cancers.
- Sunscreens are rated with an sun-protective-factor (SPF) which is essentially a measure of protection against sunburn or ultraviolet B radiatioa
- SPPF sun-protective-factor
- High SPF sunscreens have been available for almost 30 years and broader spectrum sunscreens, which also block some longwave ultraviolet light, for almost 15 years.
- SPDF sun-protective-factor
- sunscreens may reduce the incidence of non-melanoma skin cancer, but it difficult to reconcile this with the non-melanoma skin cancer epidemic.
- the situation with melanoma is less clear.
- Some studies show a protective effect and others show that sunscreens may increase the risk of melanoma.
- Basal cell carcinoma or melanoma So, testing of the effects of sunscreens with respectto skin cancer is difficult.
- sunscreens inhibit epidermal synthesis of vitamin D 3 (cholecalciferol), and thatthis promotes the growth of cancer.
- Calcitrol is a potent regulator of cell growth and differentiation. It also has an inhibitory effect on cellular death and new blood vessel growth, i.e., into tumors).
- Low vitamin D levels have been associated with breast, prostate, and colon cancer.
- New vitamin D analogues have been shown to be very effective in preventing chemical tumorgenesis in mice.
- Vitamin D3 is synthesized by epidermal keratinocytes on exposure to UVB, but must undergo activation first by 25-hydroxylation and then 1 -alpha hydroxylation to convert it to 1,25 - dihydroxyvitamin D 3 , or calcitriol, the active form of vitamin D. Traditionally, these conversions have been thought to occur in the liver and kidney exclusively. Professor Michael F. Holick at Boston" University ' has suggestecl thaffhe UV blocking characteristics of sunscreens has inhibited the natural production of vitamin D3 by the skin. He has created a controversy among the dermatological community by suggesting some unprotected exposure to natural or artificial sunlight for short periods of time in order to increase vitamin D production. Additionally, he has several patents, such as U.S. Patent No.
- the present invention provides a method of inhibiting skin cancers, precancers, photoaging and other dermatological disorders through use of vitamin D 3 .
- vitamin D 3 is provided as an ingredient in a topical sunscreen.
- cod-liver oil is provided as an ingredient in a topical sunscreen as a source of vitamin D 3 .
- a topical sunscreen containing vitamin D 3 or cod-liver oil is applied to portions of the skin subjected to exposed to sunlight.
- vitamin D 3 is provided as an ingredient in a topical lotion or cream associated with sun exposure.
- cod-liver oil is provided as an ingredient in a topical lotion or cream associated with sun exposure as a source of vitamin D 3 .
- a topical lotion or cream associated with sun exposure containing vitamin D 3 or cod-liver oil is applied to portions of the skin previously exposed to sunlight.
- Vitamin D Metabolites By Human Melanoma Cells, J Clin Endocrimol Metab, 1983, 57:627-631. Polymorphisms of the vitamin D receptor are also associated with an increased susceptibility to and worsened progress in melanoma.
- Halsall JA et al., A novel Polymorphism in the IA Promoter Region of the Vitamin D Receptor Is Associated With Altered Susceptibility and Prognosis in Malignant Melanoma, Br J Cancer, 2004: 16:765-70.
- Hutchinson PE etal., Vitamin D Receptor Polymorphisms Are Associated With Altered Prognosis in Patients Wilh Melanoma, Clin Cancer Res.2000; 6:498-504.
- Exposure to UV radiation can increase the risk of cancer.
- it causes the skin to produce vitamin D which has a cancer inhibiting effect.
- the use of sunscreens prevents me rormauon ot vitamin D in the skin Accordingly, protection against sunburn seems not to be protection against skin cancer due to variations in vitamin D formation and activation.
- the present invention resolves the conflict by providing another source of vitamin D to the skin.
- vitamin D 3 cholesterolcalciferol
- other biologically active vitamin D derivatives are added to topical sunscreens. When the sunscreen is applied, it inhibits the UV radiation and its cancer causing effects.
- the vitamin D 3 is provided to the skin.
- the skin can activate the vitamin D 3 to calcitriol to provide the anti-cancer effects at the epidermis.
- the benefits of vitamin D formation from UV radiation can be achieved without the harmful exposure.
- the present invention includes other applications of vitamin D 3 or its derivatives.
- topical products for use after exposure to the sun are generally in the form of lotions or creams containing aloe vera and other moisturizers for hydrating and protecting the skin from the exposure.
- Other ingredients are also used to maintain the skin, sooth minor burns, and prevent peeling.
- Many people use these formulations to protect and preserve their skin when they have ordinary or excessive exposure to the sun. They can also provide an opportunity to help prevent skin cancer.
- the addition of vitamin D 3 to such formulations provides for application of vitamin D 3 to the skin where it provides its cancer inhibiting effects.
- vitamin D 3 The amount and form for adding vitamin D 3 to topical sunscreens or after sun lotions in order to best achieve the benefits is still subject to research and testing.
- synthetic or natural sources of vitamin D 3 such as cod-liver oil
- the topical application of vitamin D is safe and beneficial.
- Vitamins A, E, and C are currently added to some sunscreens.
- various vitamins, herbs and other ingredients are added to after sun lotions.
- vitamin D 3 could also be added Since vitamin D 3 is lipid soluble, the sunscreen or after sun lotion should contain lipids. Otherwise, any sunscreen or after sun formulation can be used with the present invention.
- vitamin D and its analogs are of potential benefit in the treatment of photoaging. Nagpal S, et al. Vitamin D analogs: mechanism of action and therapeutic applications. CurrMedChem2001; 8: 1661-79. Thus, the addition of vi ⁇ a ⁇ un u 3 ⁇ sunscreen or a ⁇ er sun iouons may also inhibit photoaging.
