Through the UCLA tumor registry, patients treated for late-relapse malignant melanoma (after a 10-year disease-free interval) were identified and studied retrospectively. The patients were studied in regards to age, sex, primary site of the lesion, the disease-free interval, elective lymph node dissection, mode of recurrence and survival time following relapse. The histologic characteristics studied included the maximal tumor thickness, Clark's levels, rate of mitoses, and presence of ulceration. Based on the 0.84% incidence of late-relapse, the recommendation for annual life-time follow-up examinations for all patients with malignant melanoma is supported.
Our data showed that all three techniques were effective in lowering the tension required to approximate surgically created defects, with the S.T.A.R. device proving to be most effective. Undermining and the S.T.A.R. device also worked synergistically to decrease skin-closing tension.
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.
