BRCA1 and BRCA2 mutations in breast/ovarian cancer patients from central Italy.

We report on the screening of the entire BRCA1/BRCA2 coding sequence by SSCP, PTT, and direct sequencing in 68 Italian families with recurrent breast or ovarian cancer. For each investigated proband, the probability of being carrier of a BRCA1/BRCA2 mutation was evaluated using the BRCAPRO software. We detected BRCA1/BRCA2 mutations in 8 patients (11.7%). However, if considering only patients with a carrier probability >10%, the detection rate was 36.8%, confirming the usefulness of the BRCAPRO software. One change (BRCA1 4172insT) was a novel mutation not reported in BIC database.

Concentrations of galectin-3 in the sera of normal controls and cancer patients.

Galectin-3, a member of the beta-galactoside-binding animal lectins, has been implicated in tumor invasion and metastasis. Using an immunoligand assay, we assessed the circulating levels of galectin-3 in sera from cancer patients as well as from healthy controls. Low serum levels of galectin-3 were detected in healthy individuals (median, 62 ng/ml; range, 20-313 ng/ml; 95th percentile, 184.3 ng/ml). Compared with healthy individuals, galectin-3 serum levels in patients with breast, gastrointestinal, lung, or ovarian cancer, melanoma, and non-Hodgkin's lymphoma were significantly elevated (P = 0.014). Moreover, galectin-3 concentrations in sera from patients with metastatic disease were higher than in sera from patients with localized tumors. Maximum serum concentrations of galectin-3 (median, 320 ng/ml; range, 20-950 ng/ml) were found in patients with metastatic gastrointestinal carcinoma. These results suggest that circulating galectin-3 may play a role in tumor progression. The possibility of using this assay in early-stage cancer to predict metastasis should be studied.

Chromosome abnormalities in breast fibroadenomas.

A cytogenetic study on 25 breast fibroadenomas from 17 women is reported. Seven tumors in five patients showed clonal structural chromosome changes. In three patients the breaks involved chromosome 12, occurring in two tumors in band 12p12 and in band 12q15 in all three tumors of one patient. The finding of an identical aberration, t(11;12)(q21;q15), in three adenomas from the same patient strongly suggests a clonal origin of multiple fibroadenomas of the breast.

[Carcinoma of the male breast. Our experience].

A case series of 5 male patients afflicted with breast carcinoma is reported. The Authors describe symptomatology, diagnostic iter, principles of surgical treatment and results. Underlined is the wider surgical demolition in male breast cancer in comparison with females, even if natural history and biological conduct are comparable. This is because in male breast carcinoma the local and remote infiltration is more rapid than female for the less development of breast gland. Finally, indications for radiochemotherapy are comparable to female breast cancer.

[Breast cancer. Epidemiology and other factors related to incidence in various populations].

An extensive review of epidemiology, etiology, age, genetic factors, race, alimentary habits and hormonal patterns have been analysed in studies concerning patients with breast cancer. The role of other factors (the age of menopause, the geographic distribution, the action of reserpine and many possible causes) are also discussed. The evidences observed in many studies performed in the last years in different countries are compared but definitive data cannot be reached. The material reported in these studies is not homogeneous and this review can only indicate the problems still present in this field and the subjects we need to investigate in the next years.

Chronomodulated infusion of cisplatin, 5-fluorouracil and folinic acid: lack of activity in advanced colorectal cancer.

BACKGROUND: The chronomodulated infusion of 5-FU, FA and oxaliplatin allows a significant increase in dose intensity and antitumor efficacy in patients with metastatic colorectal cancer. Here we investigated if substitution of oxaliplatin with cisplatin produced a similar antitumor activity in previously untreated patients with advanced colorectal cancer. METHODS: We enrolled 21 consecutively evaluated ambulatory patients with metastatic colorectal cancer. Each treatment cycle consisted of a 5-day course of continuous chronomodulated venous infusion of drugs. Daily doses were 600 mg/m2 5-FU, 150 mg/m2 FA (L-form), and 12 mg/m2 cisplatin. The cycles were repeated every 21 days. RESULTS: All patients completed at least 3 cycles. Overall a total number of 105 cycles were administered. One partial response (lasting 3 months) and 13 stable disease (lasting from 3 to 12 months) were observed. The remaining 7 patients had progression of the disease. Hematologic and gastrointestinal toxicity was always < or = G2 in all cycles. CONCLUSIONS: The results of this study discourage the substitution of cisplatin for the more active compound, oxaliplatin, in a chronomodulated schedule of infusion with 5-FU and FA in patients with metastatic colorectal cancer.

[Juvenile papillomatosis of the breast].

The PJ, introduced by Rosen in the 1980, is a benign and localized mammary lesion in female under 30 years old. The most important clinical and histological features are: Diagnosis in juvenile age. A mass clinically localized. A nodule with histologic features of cyst, benign hyperplasia of ductal epithelium and galactophorus ducts dilatation (Swiss cheese disease). There is a correlation between patients with PJ and breast cancer there is an increment of breast cancer in familirs of patients with PJ. There is an increment of the risk to develop a K in situ in patients with PJ and apocrine metaplasia and/or adenomatosis and/or atypical mastoplasia. We describe the diffuse PJ in a girl of 23 years old from the 1996 to 2002.

Clinical evaluation of defibrotide in the treatment of arterial and venous vascular disease. A preliminary report.

Defibrotide is a new compound with antithrombotic and profibrinolytic activity. It increases the endogenous fibrinolytic activity by promoting the cellular activator of plasminogen from endothelial cells and by decreasing the concentration of its inhibitors. In this study we evaluated a total of 223 patients for a mean period of 43 days for the following vascular conditions: (a) superficial venous thrombosis; (b) prophylaxis against deep venous thrombosis; (c) peripheral vascular disease (ischaemic foot and intermittent claudication; (d) prophylaxis against TIAs in patients with carotid plaques determining embolization; (e) treatment of venous ulcerations determined by chronic venous incompetence; (f) patients with Raynaud's phenomenon and disease. The tolerability observed was good. No side effects were observed even in more prolonged treatments. The overall efficacy was good for all groups especially in comparison with other treatment already in use for these vascular conditions. In conclusion defibrotide is a particularly useful drug in these vascular diseases and can be used both for acute and chronic treatments.

Evaluation of flow in nodular tumors of the breast by Doppler and duplex scanning.

Evaluation of flow in nodular tumors of the breast may be performed by Doppler and computerized frequency analysis. In 46 nodules of the breast (22 malignant) the nodular flow velocity and frequency analysis revealed a faster flow with a significantly higher peak frequency and mean velocity. The intensity of sound which may be considered an index of the entity of flow in the nodule was larger than that observed in the normal surrounding breast tissue. In malignant nodules and generally in fast growing nodules the flow velocity and intensity was even larger. The flow intensity and velocity was also well correlated with the growth rate as reported by single patients. In elder patients a slow rate of growth even in tumors of larger size was associated with a significantly increased flow in comparison with the normal breast tissue but this increase was not particularly large when compared with fast growing nodules in younger subjects. In conclusion the evaluation of flow characteristics (mainly velocity, frequency analysis and intensity) may be a useful index of the growth rate of nodular tumors of the breast and these data may be useful to evaluate and monitor the evolution and pathophysiology of these nodules.
