BACKGROUND: To evaluate T lymphocyte subsets in pelvic and paraortic lymph nodes, in patients with FIGO stage I endometrial carcinoma at different degrees of myometrial invasion and with lymphovascular space invasion. The aim was to define an eventual modulation of regional immune reactivity useful in the therapeutic approach of the disease.
METHODS: Twenty-two women with FIGO stage I endometroid adenocarcinoma were consecutively recruited and selected for immunological study. All the patients underwent primary surgery characterized by radical hysterectomy (Piver's type III) with bilateral salpingo-oophorectomy and systematic pelvic plus paraaortic lymphadenectomy. Lymphocyte tipization was performed by Beckton Dickinson monoclonal antibodies (CD4, CD8, CD56 and CD16) immunohistochemically in frozen-sections (immune assay on lymph nodes). For statistical evaluations. Student's t test and one way analysis of variance were used.
RESULTS: Significantly higher percentages of CD4+ lymphocytes were found in pelvic than in paraaortic lymph nodes; however, by analyzing T lymphocyte content in the different pelvic nodal groups, we also observed significantly higher percentages of CD16+ and CD56+ cells in obturator nodes when compared to iliac stations. A significant increase of CD16+ and CD56+ cell percentages was then defined with respect to myometrial involvement and lymphovascular space invasion, in pelvic nodes.
CONCLUSIONS: From our results, we could not define any clinical importance of nodal lymphocyte distribution in patients with early stage endometrial carcinoma; however, the observed nodal immune reactivity in presence of myometrial invasion seems interesting, with or without lymph vascular space involvement as possible expression of neoplastic systemic diffusion.
