In 150 cases of carcinoma of the cervix the specimens obtained by radical hysterectomy and lymphadenectomy were examined by means of giant frontal section preparations which included adjacent parametria. Serial step sections of lymph nodes were performed. There were 44 cases of Stage IB, 13 of Stage IIA, and 93 of Stage IIB. Lymph node involvement was 16%, 33%, and 37%, respectively. The size of each cervical tumor was expressed in square millimeters as an "area-equivalent," the product of its vertical and horizontal diameters in the frontal plane. Cross relationships of tumor size, incidence of lymph node metastasis, border zone spread, and parametrial involvement were studied and are discussed. It is concluded that tumor size gives a better indication of tumor behavior than does clinical staging and constitutes an objective method of classifying tumors that the latter cannot attain.

To assess the safety, feasibility, and impact on survival of extraperitoneal para-aortic lymphadenectomy in the staging of patients with bulky or locally advanced cervical cancer.Between August 2001 and October 2009, 87 consecutive patients (median age 5 years) with bulky or locally advanced cervical cancer underwent extraperitoneal laparoscopic infrarenal aortic and common iliac dissection as a pretherapeutic staging procedure. Data on pathologic findings, details of surgery, postoperative complications, and disease status at follow-up were collected.The median operating time was 150 min (range 60-255 min). The mean (± standard deviation) para-aortic nodal yield was 15.5 ± 8.1 (range 4-62). In none of the patients, conversion to the transperitoneal approach or laparotomy was necessary. Histological examination revealed metastasis in 13 patients (macroscopic disease 10, microscopic disease 3). After a median follow-up of 33.4 months (range 13.3-65.9 months), 73.6% of patients were free of disease and 1.1% were alive with disease, 19.5% died from cervical cancer, and 3.3% died from other causes. After a follow-up of 3 years, no deaths or recurrences were documented, with an overall survival rate of 74.8% (95% CI 62.8%-83.4%) and disease-free survival of 86% (95% CI 74.7%-92.5%). There were no significant differences in overall survival and disease-free survival between patients with positive and negative para-aortic lymph nodes.The extraperitoneal laparoscopic para-aortic lymphadenectomy for pretherapeutic surgical staging in cervical cancer is a safe and feasible procedure that should be considered as a tool to identify lymph node positive patients who require extended-field radiation and/or chemotherapy.

Between January 1986 and June 1990, systematic para-aortic and pelvic lymphadenectomy was performed in 208 women with untreated ovarian, endometrial, and cervical cancers. This study aimed to evaluate the median number of nodes collected from each pelvic and para-aortic group and to verify a new detailed nomenclature for the various lymph node groups. The para-aortic nodes were distinguished as paracaval, precaval, and retrocaval, depending on their relationship with the vena cava. Para-aortic, pre-aortic, and retro-aortic nodes were located close to the aorta. The nodes situated between the vena cava and aorta were designated intercavo-aortic. A median of 26 (range 15-48) para-aortic nodes were collected during ovarian or endometrial cancer operations. The lymphatic system of the pelvis was divided into six groups, depending on the relationship with the pelvic blood vessels. The pelvic nodes were distinguished as common, internal and external iliac, presacral, obturator, and parametrial. In cases of cervical cancer, the median number of pelvic nodes collected was 38 (range 20-88). Such anatomical study of the lymphatic system shows that a higher number of nodes than expected can be found in the retroperitoneum.
