Recommendations for the handling and oncologic pathology report of lymph node specimens submitted for evaluation of metastatic disease in gynecologic malignancies

The nodal status is one of the strongest prognostic factors in gynecologic malignancies. Metastatic involvement of regional and distant lymph nodes represents the selection basis for adjuvant therapy in a large number of solid neoplasms. The number of resected lymph nodes is one of the most important parameters in the quality control of the surgical procedure, in particular with respect to radicality. The present paper provides recommendations for gross dissection, laboratory procedures and reporting for lymph node biopsies, lymph node dissections and sentinel lymph node biopsies (SLN) for cancers of the vulva, vagina, uterine cervix, endometrium, Fallopian tubes and the ovaries, submitted for the evaluation of metastatic disease. The pathologic oncology report should include information about the number and size of resected lymph nodes, the number of involved lymph nodes with the maximum size of metastases and the presence of paranodal infiltration. In addition, the detection of isolated tumor cells should be reported, particularly with respect to the detection method (immunostains or molecular methods). In cases of metastatic disease and carcinoma of unknown primary (CUP-syndrome), information should be given regarding the primary tumor. © Springer Medizin Verlag 2005.
