This study confirmed that mucosal melanomas are rare and could be difficult to diagnose being often amelanotic and in hidden sites. Most melanomas were thick at the diagnosis, but glans and vulvar melanomas were thinner probably because of their greater visibility. The frequency of the c-kit mutation varied depending on the initial tumour site. In our series, the prognosis was poor, independently from c-kit mutations and the patient's general health and age. The presence of metastasis at diagnosis was associated with a worse prognosis indicating the importance of an early diagnosis.
Cet article présente la mesure de la période, T1/2 = (2,15 ± 0,08) ns du premier niveau excité de 40Ca. Les mesures de coïncidences différées dans 132I ont permis de fixer l'ordre d'émission des deux rayons gamma de 52 keV et 232 keV ; les périodes sont égales à T1/2 = (0,96 ± 0,04) ns pour le niveau à 52 keV et à T1/2 = (1,42 ± 0,05) ns pour le niveau à 284 keV. Ces valeurs, et des mesures du coefficient de conversion interne α K, permettent d'attribuer les ordres multipolaires M1 + E2 et E2 respectivement pour les transitions de 52 et 232 keV
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
