Ultrasound examination in ovarian cancer patients. A comparison with second look laparotomy

A series of 129 patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IV ovarian cancer, were evaluated with ultrasound examination and second look surgery. Results of both modalities were correlated in order to assess the reliability of ultrasound in detecting residual disease. After six cycles of chemotherapy, ultrasound was negative in 94 patients and positive in 35 patients. At second look, 57 patients were in complete pathologic remission, 16 had microscopic residual disease, 23 had macroscopic disease less than 2 cm, and 33 had macroscopic disease greater than 2 cm. Correlating ultrasonography and laparotomy, high correlations were seen in patients with no residual disease (92.2%); on the other hand, ultrasound examinations exhibited poor sensitivity and specificity in patients with microscopic disease (6.2%) and residual disease less than 2 cm (8.6%). Using ultrasound discrimination among patients with no residual disease, microscopic disease, or macroscopic disease less than 2 cm does not appear possible. Our suggestion is that ultrasound is not able to replace second look laparotomy in the detection of minimal residual disease in ovarian cancer patients.     

Effect of lisuride on inhibition of lactation and serum prolactin

Lisuride, a new semisynthetic ergot derivative, was given to 53 women to inhibit lactation; 26 women had 300 micrograms daily and 27 had 600 micrograms daily for seven days. Eight lactating women acted as controls. Lisuride effectively inhibited lactation and also suppressed the serum prolactin levels; the latter effect was dose related. Lisuride produced no untoward side effects.     

The association between p53 expression, stage and histological features in endometrial cancer

OBJECTIVE: Alterations of the p53 gene have been widely suggested to be relevant to the development of endometrial carcinoma. However, contradictory results have been reported when immunohistochemical determination of p53 expression has been correlated with stage and histological features of the tumours. STUDY DESIGN: Pathology findings were reviewed and p53 immunoperoxidase staining was performed in 240 cases of endometrial carcinoma. RESULTS: Uterine papillary serous adenocarcinomas showed significantly higher p53 overexpression than uterine endometrioid adenocarcinomas (100.0% versus 61.0%, p<0.005). p53 overexpression was significantly higher in the secretory variant (85.7%) than in the typical endometrioid carcinoma (60.0%) (p<0.05). p53 expression did not differ between early (stage I) and advanced (stage II-IV) carcinomas. Likewise, no difference was observed in p53 expression among different architectural grades. The incidence of metastasis to lymph nodes was similar in p53 positive (13.7%) and in p53 negative tumours (12.5%). CONCLUSION: In the present series, p53 immunostaining did not differ between cases with different FIGO stages or histologic characteristics of the tumours. No simple relationship exists between the immunohistochemical determination of p53 expression and the biological aggressiveness of endometrial carcinomas.     

Cytological analysis of the distension fluid used during diagnostic office hysteroscopies in patients with suspected endometrial pathology

OBJECTIVE: Evaluation of the feasibility and usefulness of cytological analysis of the distension fluid used during diagnostic office hysteroscopy in patients with suspected endometrial pathology. METHODS: In 243 consecutive patients undergoing diagnostic hysteroscopy for suspected endometrial pathology a few milliliters of the distension medium used for uterine visualization were collected and sent for cytological analysis. Findings of these "endometrial washings" were compared to visual hysteroscopic impression, endometrial biopsy and uterine histology--when available. RESULTS: Endometrial washings were considered adequate in 227 patients (93.4%). In 12 cases (5.3%) atypical cells were detected: all of these presented either atypical complex hyperplasia or endometrial cancer at the final histological evaluation of the uterus. Four of the 16 (25%) patients diagnosed with endometrial cancer or atypical complex hyperplasia at the final histopathological analysis of the uterus had inadequate washings. No patient with cancer or atypical hyperplasia had negative cytology. CONCLUSIONS: Collection and analysis of the distension fluid is feasible and, when positive, has a remarkable value in the diagnosis of endometrial cancer and its precursors.     

Serum prolactin and ovarian function after discontinuation of drug treatment for hyperprolactinaemia: a study with bromocriptine and metergoline

Serum prolactin (PRL) was estimated for up to 2 months after discontinuation of therapy with either bromocriptine (n = 33; 15 with idiopathic disease, 12 with pituitary microadenoma, and six with macroadenoma) or metergoline (n = 23; 11 with idiopathic disease, and 12 with microadenoma) that had been administered for 8-30 months. Only five patients treated with bromocriptine and two treated with metergoline had PRL levels that remained normal or below 50% of pretreatment values. Among the patients followed-up for up to 12 months, four showed a fall in PRL at 3-4 months, but this was followed by a rise in one patient. Five patients showing persistently lower or normal PRL after drug withdrawal were retested with thyrotrophin-releasing hormone; the two responsive women also had a normal response before treatment. Of 10 patients followed for 9 months, three had persistently normal PRL levels. Amenorrhoea and anovulation recurred, with some delay, in all the patients showing PRL rebound except one. Medical treatment of hyperprolactinaemia only rarely results in permanent benefit.
