Urinary Melatonin Levels and Skin Malignancy

چکیده
Melatonin inhibits tumor genesis in a variety of in vivo and in vitro experimental models of neoplasia. In industrialized societies, light at night, by suppressing melatonin production, poses a new risk for the development of a variety of cancers such as breast cancer. This effect on skin has been previously studied only in animals and not in humans. Our goal was to examine the relationship between 24-hour 6-sulphatoxymelatonin levels and skin cancer in a case-control study of 70 patients with skin cancer and 70 healthy individuals. The level of 6-sulfatoxymelatonin was measured in 24-hour urine by the ELISA method. In the case group, 55 (78%) patients had basal cell carcinoma and 15 (22%) had squamous cell carcinoma. The mean level of 24-hour urine 6-sulfatoxymelatonin was significantly higher in the control group (P<0.001). Also, sleep duration had a significant difference between the two groups (P=0.001). It seems that a low level of 24-hour urinary 6-sulfatoxymelatonin renders human beings prone to skin cancer. This association, however, requires further investigation.

متن کاملThe Reduction in Circulating Melatonin Level May Contribute to the Pathogenesis of Ovarian Cancer: A Retrospective Study
Ovarian cancer is the third most common gynaecological malignancy. Changes in circadian rhythms such as bright light exposure may affect female reproductive physiology. Night shift work is associated with higher risks of developing gynaecological cancers. In addition, the season of birth is also suggested as an important environmental risk factor for developing gynaecological cancers. Melatonin...
متن کاملUrinary Melatonin in Depression
This report is based on a study of 12 cases of depression (8 endogenous, 4 neurotic) with a view to explore the possible association between urinary melatonin and the illness prior to and following treatment. While cases of endogenous depression had low 24 hour as well as nocturnal urinary melatonin levels, the neurotic depressives showed higher than normal levels. A rise in the 24 hour melaton...
متن کاملSerum melatonin and urinary 6-sulfatoxymelatonin in major depression.
In this study, serum melatonin and urinary 6-sulfatoxymelatonin (aMT6s) were measured in 14 major depressive inpatients, compared to 14 matched controls according to age, gender, season and hormonal treatment in women. Moreover, the relationship between serum melatonin and urinary aMT6s levels was analysed in the two groups. Results indicated that the two groups of subjects showed a clear melat...
