Role of reoperation in recurrence of adrenal cortical carcinoma: results from 188 cases collected in the Italian National Registry for Adrenal Cortical Carcinoma.

BACKGROUND: Recurrence of adrenal cortical carcinoma (ACC) after radical surgery is a common finding. Although successful reoperations have been reported with encouraging results, most published experiences are anecdotal and based on few cases. We report the results of surgical treatment for recurrent ACC in a multiinstitutional series. METHODS: One hundred eighty-eight cases of ACC were collected in a national registry. A complete follow-up was obtained in 179 cases. At initial diagnosis 92 patients had local disease (stage I or II). One hundred seventy patients underwent surgical treatment, considered radical in 140; in this group, recurrent disease was observed in 52 cases (37%) after a mean disease-free interval of 21.7 months. RESULTS: Adjuvant chemotherapy was ineffective in ameliorating the prognosis. The mean survival in 20 patients who underwent reoperation was significantly higher (15.85 +/- 14.9 months) than in nonreoperated cases (3.2 +/- 2.9 months). Five-year actuarial survival in reoperated patients is significantly better than in nonreoperated patients (49.7% versus 8.3%, respectively). CONCLUSIONS: Although the prognosis of this tumor is still poor, surgery is the only effective therapy; reoperation allows survival comparable to that observed in patients without recurrent disease. An aggressive strategy for recurrent ACC is advisable until prospective studies demonstrate a real effectiveness for chemotherapy.

Transaxillary access to perform hepatic artery infusion (HAI) for secondary or primitive hepatic tumors.

There is a renewed interest in locoregional chemotherapy for hepatic tumors; trials in progress are experimenting with new therapeutic protocols with an approach combining different systems of infusion (HAI and systematic) or with the use of HAI as adjuvant or neoadjuvant of the surgical treatment or cryosurgical treatment of the hepatic metastases from colo-rectal cancer. However, HAI is practicable principally with the implantation of a catheter in the hepatic artery (port of Infusaid) by laparotomic access. This intervention limits wide-scale use of the infusion method, traditionally less toxic and more efficient in terms of results than systemic treatment. Limited experience of percutaneous access for HAI required more catheterisation with repeated puncturing of the artery and later necessity of surgery in cases of HAI with continuous spraying. Motivated by the first experience of certain authors from Chiba University, we have devised a system of catheterisation of the hepatic artery with transcutaneous access, with subcutaneous port that allows the use of HAI without recourse to the usual intervention. Access is made through the left axillary artery; the positioning of the catheter is in the hepatic artery with possible embolization of the collateral or abnormal hepatic artery that could hamper complete diffusion of the drug to the liver, or increase to toxicity of the method. The implantation is done in day-surgery. In the cases performed up to now there have been no complications regarding the method and the catheters function all perfectly thanks to the collaboration of ematologists to avoid possible thrombosis of the catheters.

[Evaluation of the effect of flunitrazepam on the lower esophageal sphincter in man with intraluminal manometry].

The effect of Flunitrazepam on the human lower oesophageal sphincter is evaluated. Pressure in the LOS and GOR using the Acid Reflux Test was evaluated in 22 surgical cases at rest (after ingestions of a placebo and Flunitrazepam). The results obtained indicate that the LOS pressure variations induced by flunitrazepam significantly increase the probability of GOR.

[Retrosternal thyroid cancers. Considerations on 25 cases].

Intrathoracic thyroid cancer is an unusual finding, and few reports are available on this item. Literature data have been reviewed, and some considerations on epidemiologic characteristics of the disease and on its treatment were gained from an analysis of reports based on the files of I Surgical Clinic of the University of Turin, Surgical service of the Oncological Department of the S. Giovanni Battista Hospital and II Pathological Anatomy Service of the University of Turin. No correlation was found between previous thyroid disease, sex, histological findings, previous radiotherapy and incidence of the disease. Older age at the onset and recurrent laryngeal nerve lesions are frequently associated with intrathoracic thyroid cancer; papillary carcinoma is rarely found. Intrathoracic situation is not likely, in Author's opinion, to affect the long term prognosis more than usual risk factors.

Presence and characterization of prolactin receptors in human benign breast tumours.

Prolactin receptors have been determined in 64 benign breast tumours. A specific binding of 0.5% or more (with a range of 0.5-3.3%) was found in 34.4% of the cases and was considered prolactin-receptor-positive. The binding was found to be specific only for lactogenic hormones. By Scatchard analysis the dissociation constant was 2.55 X 10(-10) mol/l and the binding capacity was 4.6 fmol/mg protein.

[Initial immunologic evaluations in breast and thyroid cancer].

In evaluating pre- and post-operative immunological status of 15 patients with malignant breast and thyroid tumors and of 9 patients with benign breast and thyroid lesions, rosette E test, CEA, cortisol, immunocomplexes and determination of circulating leukocytes, B lymphocytes and immunoglobulins was employed. The obtained data were not significative to show a lack of immune response in tumor bearing patients. Among the reexamined parameters, CEA was the only one that apparently correlated with prognosis; its serum levels, being at a high rate in a high percentage of malignancies, tended to fall down after surgical treatment.
