Relation between steroid receptor status and body weight in breast cancer patients.

Obesity is known to adversely affect breast cancer prognosis. Since obesity is associated with increased oestrogen levels, and oestrogens are growth stimulators of oestrogen receptor (ER)-positive breast carcinomas, we evaluated the relationship between the ER and progesterone receptor (PR) status of the neoplastic tissue and obesity in a series of 615 breast cancer patients. Both ER and PR concentrations were significantly and positively correlated with obesity by multiple regression analysis. Furthermore, the estimated probability of having an ER+/PR+carcinoma was significantly higher in obese patients (odds ratio 2.65, 95% confidence interval 1.56-4.48). This association between receptor-positive status and obesity was observed both in premenopausal and postmenopausal patients. Our data suggest, therefore, that obesity plays a role in determining the ER status of breast cancer and raise the possibility that ER presence in breast carcinomas occurring in obese patients is not indicative of a favourable prognosis.

Electric stimulus energy and the clinical response to electroconvulsive therapy.

The relationship between electric stimulus energy and clinical response was examined in depressed patients receiving electroconvulsive therapy (ECT) under routine clinical conditions with a protocol which dichotomized the stimulus energy by patient age. There was no significant difference in the number of treatments and cumulative seizure duration between groups. The results support the observation that the stimulus energy may contribute to the therapeutic effect of ECT. Reduction of that energy in order to minimize side-effects may compromise the therapeutic effectiveness. The implications for dosage strategies in routine clinical practice are discussed.

[Reconstructive microsurgery].

Progress in microsurgery has been accomplished by the technical improvements of the operative microscope and other delicate surgical instruments. Therefore, even small arteries as well as female tuba and male deferens, either presenting mechanical obstruction or a section, can be reconstructed. The same procedure may be applied in case of nerve injuries. Since Microsurgery was born, it has been employed in different medical fields offering lately good chances in sterility. Furthermore, microsurgical techniques offer a great support to Plastic Surgery. In fact, it is possible to repair wide tissue damages of the skin, muscles or bones using free flaps. The percentage of success of this Surgery increased the overall percentage obtained in General Surgery. Therefore a close multidisciplinary relation between the different Medical fields is absolutely required for a correct application of microsurgical techniques.

[Clinical significance of the determination of serum phosphohexose isomerase in malignant neoplasms].

The results of a preliminary study on the serous level of PHI in patients undergoing treatment at the Catania Oncology Institute are reported. Of 53 subjects with ongoing cancer, higher than normal values were encountered in 70% of cases. This percentage rose to 82.3% in cancer patients with metastasis affecting the skeleton. Of 12 subjects who underwent mastectomy with no clinical signs of recurrence only three showed abnormal values while in no case of fibrocystic mastopathy were levels higher than normal observed. A constant correlation was identified between effectiveness of surgical, radiotherapeutical or medical treatment and reduction in serous level of PHI. The usefulness of this investigation in oncology is thus confirmed.

[Receptor status and ovarian function in carcinoma of the breast].

The Authors have evaluated the relationship between the presence of estrogen (ER) and progesterone (PgR) receptors and the ovarian function in 321 consecutive and unselected women who have undergone surgery for breast cancer. A significant relationship was found between the presence and the concentration of steroid receptors (ER and PgR) in the neoplastic tissue and the ovarian function. The Authors confirm the importance of considering the menopausal status in the evaluation of the results of steroid receptor assay.
