Patients with micrometastasis to para-aortic lymph nodes may benefit from extended field chemoradiation. To determine the rate of para-aortic node micrometastasis in patients with locally advanced cervical cancer undergoing laparoscopic extraperitoneal para-aortic lymphadenectomy.
We prospectively identified consecutive patients diagnosed with stage IB2-IVA biopsy-proven cervical cancer. Eligible patients included those who were candidates for treatment with radiotherapy and concurrent chemotherapy and had no evidence of para-aortic lymphadenopathy (all lymph nodes<2cm in diameter) by preoperative computed tomography or magnetic resonance imaging. All patients underwent preoperative positron emission tomography/computed tomography and laparoscopic extraperitoneal para-aortic lymphadenectomy. All lymph nodes were assessed for metastasis by routine hematoxylin-eosin (H&E) staining. Ultrastaging (serial sectioning) and immunohistochemical analysis were performed in H&E-negative specimens.
Thirteen (22%) of 60 consecutive patients had para-aortic lymph node metastases detected on routine H&E staining. Of the remaining 47 patients, one (2.1%) had evidence of micrometastasis, which was detected by ultrastaging. This patient completed whole pelvic radiotherapy and chemotherapy but had a recurrence 27months after completion of therapy.
The rate of para-aortic node micrometastasis in patients with locally advanced cervical cancer is low. The role of routine ultrastaging and immunohistochemical analysis in such patients remains uncertain. Future studies are needed to determine the clinical impact of para-aortic node micrometastasis in patients with locally advanced cervical cancer.

A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
The local lymph node assay (LLNA) is an alternative method for the identification of chemicals that have the ability to cause skin sensitization and allergic contact dermatitis. Endpoints have been established so fewer animals are required and less painful procedures are used.
