[Melanoma of the skin and pregnancy].

Out of 2018 patients, skin melanoma occurred in IO2 (5%) cases during pregnancy. Three-, five- and ten year survival was analysed in the latter cases versus term of pregnancy, abortion and the stage of the disease. Also comparison was made between the said group, another 42 females who developed tumors during lactation period and 599 normally-cycling females of reproductive age who were not pregnant when melanoma appeared (controls). Significantly lower 10-year survival was observed in pregnant patients, as compared with those who were not pregnant (p less than 0.05). Five- and ten-year survivals were significantly lower in cases of stage I tumor during the latter half of pregnancy than in skin melanoma patients who were not pregnant (p less than 0.05). Abortion during the first half of pregnancy was found to produce an adverse effect on prognosis in stage I tumor patients while this effect was reversed in stage II tumor. No significant differences were found between 3-, 5- and 10-year survival in melanoma patients who had pregnancies before the disease and those who had not (p greater than 0.05).
