title: Pelvic and parametrial lymph nodes in the quality control of the surgical treatment of cervical cancer.
abstract: Between 1971 and 1989 a total of 420 patients underwent radical abdominal hysterectomy with pelvic lymphadenectomy at our hospital for stage Ib, IIa, or IIb cervical cancer. The entire lymph node material was processed in serial sections and stained with hematoxylin and eosin. Lymph nodes were counted and the sizes of metastases measured. The entire surgical specimen was fixed as a whole with the parametria spread out. The size of the tumor was measured by morphometry. Cases treated between 1971 and 1979 were compared with those treated between 1980 and 1989. The median number of pelvic lymph nodes removed per patient was 24 between 1971 and 1979 and 35 between 1980 and 1989 (P = 0.0001). Significantly more nodes were removed at each node group (P = 0.01). Between 1971 and 1979 no common iliac nodes were obtained in 56 patients and no left common iliac nodes in 74 patients, compared to only 1 and 6 patients, respectively, between 1980 and 1989. The rate of patients with positive lymph nodes was 33% (63/195) between 1971 and 1979 and 55% (101/225) between 1981 and 1989 (P = 0.008). In the first study period the median number of parametrial lymph nodes was 2 compared to 3 in the second period. The rate of patients with positive parametrial lymph nodes increased from 15 to 24% (P = 0.027). The results of this review indicate that exacting morphologic processing of the entire lymphatic tissue obtained at surgery permits accurate postoperative staging and assessment of risk factors for decisions on adjuvant treatment. Histologic evaluation objectifies the radicality of the procedure and is useful in the quality control of the surgical treatment of cervical cancer.
