[Computerized tomography versus lymphography in the assessment of lymph node metastasis in epithelial carcinoma of the ovary].

We investigated the accuracy of both lymphangiography and CT in detecting lymph node metastases in 59 patients evaluated preoperatively and subsequently submitted to surgery with selective/systemic pelvic and paraaortic lymphadenectomy. CT accuracy was also investigated in 46 patients with a clinically suspected relapse of ovarian cancer (verified by means of clinical and/or CT follow-up in 36 patients, by laparotomy in 7, by fine-needle biopsy in 1 and by necroscopy in the last 2). In the first group (previously untreated patients) the overall results in the pelvis were, respectively, for lymphangiography and CT: 94.9% vs 89.8% accuracy, 86.6% vs 60% sensitivity, 97.7% vs 100% specificity, and 92.8% vs 100%, 95.5% vs 88% positive and negative predictive values. In the paraaortic region the results were: 89.1% vs 86.5% accuracy, 73.3% vs 66.6% sensitivity, 100% specificity for both techniques, 100% positive predictive value, and 84.6% vs 81.5% negative predictive value. In the second group (clinically suspected relapse), CT accuracy, sensitivity, and specificity were, respectively: 91.3%, 81.8%, and 100%. Our experience demonstrated a high incidence of lymph node metastases in ovarian cancer, both in pelvic (15/49; 25.5%) and especially in aortic (15/37; 40.5%) locations in untreated patients, and an even higher incidence in relapses (22/42; 52.5%). The high specificity and positive predictive value of CT depended on the fact that there were no false positives. We arbitrarily considered as metastatic a lymph node with phi greater than 2 cm, and this threshold seemed to be of clinical value since it made a good predictor of metastases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Current status of research of a lymphatic system in the nervous system: initial trials with cerebral lymphography].

After having recognized the existence of post-mortem intra-cerebral circulation of a coloring substance with lymphatic resorption, the author is continuing his research by injecting a product sharing the same characteristics: Iotrolan. Brain X-rays show brain circulation from the cortex to the ventricular cavities and from the spinal cord to the bulbar area and to the cerebellum. One question deserves to be asked: what is this circulation?

[Lymph node metastasis of carcinoma of the cervix uteri. Role of lymphography and computerized tomography].

The presence of lymph nodal metastases in the patients affected with carcinoma of the uterine cervix is of the utmost clinical relevance. In the Radiology, Obstetrics and Gynecology Departments of Pavia University we have evaluated the accuracy of lymphangiography and CT in recognizing lymph nodal metastases in 95 patients, 58 of them evaluated preoperatively (49 subsequently submitted to radical hysterectomy). CT accuracy was also evaluated in 37 patients with a clinically suspected relapse of cervical cancer. In the first group the overall results were: 91% accuracy, 88% sensitivity, 92.5% specificity for lymphangiography and 87.9% accuracy, 72.2% sensitivity, and 95% specificity for CT (in 49 patients, stage I-II, submitted to lymphadenectomy, lymphangiographic accuracy was 91%, sensitivity was 88%, specificity 92% versus CT accuracy 85.7%, 44.4% sensitivity, and 95% specificity). In the second group (relapse) CT accuracy, sensitivity and specificity were 94%, 100%, and 91%, respectively. In conclusion, lymphangiography gives better results than CT in the patients with early stages (I-II) of the disease. In advanced stages and relapses CT was found to have high accuracy in demonstrating lymph node status. This information is useful for treatment planning and for avoiding unnecessary surgical exploration.

[Hepatography in the course of lymphography].

Two cases are presented in which epatography occurred following lymphangiography. The morphologic findings and their changes in subsequent controls are described. Attention is pointed on the uncommon persistance of epatography for a few months from lymphangiography.
