For lymph nodes measuring less than 5. Int J Radiat Oncol Biol Phys. In these patients, a residual node measuring larger than 1 cm in maximum transverse diameter should be resected, since these nodes will contain mature teratoma in 50% of cases and vital cancer in 35%.

Pelvic lymph node anatomy and nomenclature are reviewed with schematic illustrations and clinical examples from patients with pelvic tumors. Studies in uterine and cervical cancer — , for example, have shown high specificity approaching 100% , but the technique is limited due to lower sensitivity for nodal metastasis from uterine cancers , sensitivity, 53%—60% and cervical cancer , sensitivity, 58%—91%.

Prognostic factors in carcinoma of the penis: multivariate analysis of 145 patients treated with amputation and lymphadenectomy. This problem may be compounded if the lesion is not directly adjacent to the gut wall, if it is small, or if there is excessive respiratory movement. The treatment for this depends on the inflammation of the aorta. The Cox proportional hazards model was applied for univariate and multivariate analyses. These are nonregional nodes for prostate cancer and therefore represent M1 disease. After adequacy is determined, the specimen remaining in the needle is flushed into a preservative medium, from which Cytospin preparations can be prepared for immunohistochemical testing for immunologic classification. The set of lymph nodes located near the third and fourth lumbar vertebral bodies, just behind the aorta, is called the retroaortic or postaortic group.
