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.

  • 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.

  • Vitamins A, E, and C are currently added to some sunscreens.

  • 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.

Abstract

Une plus grande utilisation de crèmes solaires, tout en limitant les dommages à l'ADN, peut favoriser la croissance du cancer en évitant la synthèse de vitamine D dans la peau. Selon cette invention, les effets bénéfiques des rayonnements UV sont obtenus par incorporation de vitamine D dans la crème solaire topique ou des lotions après-solaires. L'application de crème solaire protège contre les effets néfastes des rayonnements UV et la vitamine D y étant contenue est activée par la peau en calcitriol afin de prévenir le cancer. Etant donné que le calcitriol favorise également la croissance et la différenciation cellulaire, la crème solaire topique ou le produit après-solaire contenant de la vitamine D peut être bénéfique contre le photovieillissement.
