Eighty-one female patients with phyllodes tumors of the breast, surgically treated from 1974 to 1983, were studied. Their age ranged from 9 to 88 years. According to histology, the series was divided into three groups, of 28 (34.5%) benign tumors, 32 (39.5%) border-line tumors, and 21 (25.9%) malignant tumors. Because ten patients were lost to follow-up, only 71 women could be evaluated. All the patients had received surgical treatment: 51 women had been treated conservatively (11 enucleations, 40 wide resections), and 20 had undergone radical operations (13 underwent total and five underwent subcutaneous mastectomies, whereas one underwent modified and one underwent radical mastectomy). The mean follow-up, for the three groups, was 106 months for benign, 84 months for borderline, and 82 months for malignant tumors; in no case was radical surgery followed by local recurrence: of 51 women conservatively treated, 14 experienced local relapse, i.e., one of 24 women with benign, ten of 22 with borderline, and three of 8 with malignant lesions. Only two of 47 patients (4.2%) with borderline or malignant tumors developed distant metastasis and died from disease. No relationship between tumor size and risk of local recurrence could be demonstrated, and no difference could be identified between borderline and malignant lesions, in terms both of local and distant relapse. Local recurrences do not appear to affect survival: as a consequence, wide resection should be the primary treatment. Enucleation is to be proscribed. Total mastectomy has been indicated for very large tumors and for local recurrences of borderline and malignant lesions. Axillary dissection is not worthwhile.
CDKN2A germline mutation frequency estimates are commonly based on families with several melanoma cases. When we started counseling in a research setting on gene susceptibility analysis in northern and central Italy, however, we mostly found small families with few cases. Here we briefly characterize those kindred, estimate CDKN2A/CDK4 mutation test yields, and provide indications on the possibility of implementing formal DNA testing for melanoma-prone families in Italy. In September 1995 we started genetic counseling in a research setting at our Medical Genetics Center. Screening for CDKN2A/CDK4 mutations was performed on families with two melanoma patients, one of whom was younger than 50 years at onset, the other complying with one of the following: 1) being a first-degree relative, 2) having an additional relative with pancreatic cancer, or 3) having multiple primary melanomas. Sixty-two of 67 (80%) melanoma cases met our criteria. Four previously described CDKN2A mutations (G101W, R24P, V126D, and N71S) were found in 21 of the 62 families (34%) with a high prevalence of G101W (18/21). The percentage of families with two melanoma cases/family harboring a mutation was low (7%, 2/27), but rose to 45% (9/20) if one of the melanoma patients carried multiple melanomas or if pancreatic cancer was present in that family. In the 15 families with three melanoma cases the presence of a mutation was higher (67%, 10/15) and reached 100% in the 4 families with four or more melanoma cases. Our results suggest that CDKN2A/CDK4 counseling-based mutational analysis may be reasonably efficient also for families with two melanoma cases, if one patient carries multiple melanomas or if pancreatic cancer is present in the family.
Two hundred and seventy-seven consecutive patients with T3b-T4 breast cancer referred to the Milan Cancer Institute between 1973 and 1980 were treated with a combined modality approach. Chemotherapy (CT) consisted of AV, i.e. adriamycin (60-75 mg/m2 day 1) and vincristine (1.2 mg/m2 days 1 and 8) and was given for three to four cycles prior to local regional modality. Local-regional treatment consisted of either radiotherapy (RT) in 198 patients or surgery (S) in 79 women. Additional chemotherapy was then administered to a total of 205 patients. In the absence of distant metastases, frequency of good local control was significantly inferior in patients given CT + RT (63.9 per cent) compared to those treated with CT + RT + CT (75.4 per cent) and CT + S + CT (82.3 per cent, P = 0.033). Also freedom from progression (FFP) and overall survival (SURV) were significantly superior in the groups receiving more prolonged chemotherapy treatment compared to patients treated with CT + RT (FFP: P less than 0.0001; SURV: P = 0.002). None of the variables examined was able to affect the response rate, while axillary nodal status and tumor size played a major role in the duration of FFP and SURV. Our findings indicate that a more aggressive treatment is needed to improve current results in this stage of disease. To overcome the problem of local-regional recurrence, treatment should probably begin with cytoreductive surgery followed by postoperative radiotherapy in all patients with the exception of those having inflammatory carcinoma. Systemic treatment should then be delivered to control distant micrometastases.
566 stage-II melanoma patients treated at the National Cancer Institute of Milan, Italy, were analyzed to evaluate the prognosis. Among the criteria considered, four were significantly associated with survival when considered as single factors: growth pattern, levels of invasion, the number of involved lymph nodes, and the extent of metastatic growth. As regards growth pattern, the observed 5-year survival rates were 41.9% for superficial spreading melanoma and 20.5% for nodular melanoma (P = 10(-3)). As regards levels, the 5-year survival rates were as follows: level II, 20.9%; level III, 33.1%; level IV, 43.2%; level V, 10.2% (P = 10(-3)). Patients with a partial node metastasis had 64.5% 10-year survival, while those with extension beyond the capsule had 32.6% 10-year survival (P = 10(-9). Patients with one metastatic node had 43.4% 10-year survival, and patients with three or more positive nodes had 26.0% 10-year survival (P = 10(-9)). Multifactorial analysis shows that growth pattern and extent of node metastases significantly affect survival (P = 10(-2) and P = 10(-4), respectively) while the number of involved nodes turns to borderline P-value (0.051) and the levels are no longer significant (P = 0.4).
