This paper assesses the effect of estradiol on the in vitro growth of fibroblast taken from human breast skin. It was observed that estrogens stimulate the proliferation of phenotypically adult fibroblasts; that there is a threshold increase of hormonal concentration which can trigger off this process; and that the size of the single dose is more important than the number of doses of hormone received.
The paper reports the results of a study to assess the effects on erythrocytic deformability of the induction of hepatic metastases of breast cancer in an animal model. The results demonstrate a reduced level of erythrocytic deformability induced by tumor development.
Bacterial vaginosis (BV) is a well characterized disease, defined Amsel's criteria, whose incidence is significantly increased during chemotherapy for gynecologic malignancies, as previously reported by the authors. Nine patients out of 14 (64%) who were receiving adjuvant chemotherapy for gynecologic tumors showed a clinical and laboratory evidence of bacterial vaginosis and were treated with cetyltrimethilammonium naproxenate vaginal douches. Results were analyzed up to the completion of oncologic chemotherapy: a high efficacy and tolerability for the topical treatment was demonstrated in all cases.
OBJECTIVE: To evaluate colposcopy in the monitoring of patients affected by locally advanced cervix cancer treated with primary chemotherapy. MATERIALS AND METHODS: Eight patients (42-54 years old) affected by squamous cervical cancer locally advanced (stage FIGO IIa "bulky"/IIb/III) were treated with primary chemotherapy (cisplatin 50 mg/m2 vincristin 1 mg/m2 bleomicin 30 UI in 24 hours continuous infusion q 7 days for 3 cycles). Colposcopy was performed before chemotherapy, after the second cycle and at the end of chemotherapy. RESULTS: Two pathological complete responses, 5 partial responses and one case of stable disease were observed. Patients with complete and partial response were treated with radical hysterectomy. In responding patients we observed a typical sequence of colposcopic findings. Regression of distinctive malignancy feature, reduction of atypical vessels, gradual disappearance of peripheral lesions and centripetal reepilization of the cervix were sequentially registered. At the end of treatment the cervix appeared with a colposcopy imaging as well as a centripetal squamous complete or incomplete metaplasia, open--for most part--glandular exit and weak acid-iodic positivity. CONCLUSION: In responding patients we observed a typical sequence of colposcopy finding, useful in order to evaluate the effects of chemotherapy and to programme the surgical approach.
