In a retrospective multicentric analysis, 63 women treated between 1941 to 1988 for Hodgkin's disease (HD) subsequently developed 76 breast cancers (BC). The median age at diagnosis of HD was 26 years (range 7-67), and 22 women (35%) were 20 years old or less. Exclusive radiotherapy (RT) was used in 36 women (57%) and combined modalities with chemotherapy (CT) in 25 (39%). Breast cancer occurred after a median interval of 16 years (range 2-40) and the median age at diagnosis of the first BC was 42 years (range 25-73). TNM classification (UICC, 1978) showed 10 T0 (non-palpable lesions) (13%), 20 T1 (26%), 22 T2 (29%), 8 T3 (11%), 7 T4 (9%) and 9 Tx (12%), giving altogether a total of 76 tumours, including, respectively, 5 and 8 bilateral synchronous and metachronous lesions. Among the 68 tumours initially discovered, 53 ductal infiltrating, one lobular infiltrating and two medullary carcinomas were found. Moreover, two fibrosarcomas and 10 ductal carcinoma in situ (DCIS) were also found. Among 50 axillary dissections for invasive carcinomas, histological involvement was found in 31 cases (62%). 45 tumours were treated by mastectomy, without (n = 35) or with (n = 10) RT. 27 tumours had lumpectomy, without (n = 7) or with RT (n = 20). 2 others received RT only, and one only CT. 7 patients (11%) developed isolated local recurrence. 20 patients (32%) developed metastases and all died; 38 are in complete remission, whereas 5 died of intercurrent disease. The 5-year disease-specific survival rate by the Kaplan-Meier method was 61%. The 5-year disease-specific survival rate for pN0, pN1-3 and pN > or = 3 groups were 91%, 66% and 0%, respectively (P < 0.0001) and 100%, 88%, 64% and 23% for the T0, T1, T2 and T3T4 groups, respectively. These secondary BCs seem to be of two types: a large number of aggressive tumours with a very unfavourable prognosis (especially in the case of pN > 3 and/or T3T4); and many tumours with a 'slow development' such as DCIS and microinvasive lesions, especially in patients treated exclusively by RT. Moreover, a very unusual rate of bilateral tumours (21%) was observed. These secondary BC could be 'in field', in 'border of field' or 'out of field'. However, a complete analysis of doses delivered by supradiaphragmatic irradiation was often very difficult, due to large variations in several parameters. We conclude that young women and girls treated for HD should be carefully monitored by clinical examination, mammography and ultrasonography.

From 1970 to 1992, 31 pure ductal carcinoma in situ (DCIS) of the male breast treated in 19 French Regional Cancer Centres were reviewed. They represent 5% of all breast cancers treated in men in the same period. The median age was 58 years, but 6 patients were younger than 40 years. TNM classification (UICC, 1978) showed 12 T0 (discovered only by bloody nipple discharge), 10 T1, 5 T2 and four unclassified tumours (Tx). 11 patients (35.5%) had clinical gynecomastia, and three (10%) had a family history of breast cancer. 6 patients underwent lumpectomy, and 25 mastectomy. Axillary dissection was performed in 19 cases. 6 cases received postoperative irradiation. 15 out of 31 lesions were of the papillary subtype, pure or associated with a cribriform component. The size of the 12 measured lesions varied from 3 to 45 mm. All lymph nodes sampled were negative. With a median follow-up of 83 months, 4 patients (13%) presented a local relapse (LR), respectively, at 12, 27, 36 and 55 months. 3 of these patients had been initially treated by lumpectomy. In one case LR was still in situ, but already infiltrating in the 3 others. Radical salvage surgery was performed in 3 cases, but one patient developed metastases and died 30 months later. The last patient was treated by multiple local excisions and tamoxifen. One 43-year-old patient developed a contralateral DCIS and three others developed a metachronous cancer. The aetiology and risk factors of male breast cancer remain unknown. Gynecomastia, which implies an imbalance between androgen and oestrogen, may be a predisposing factor. As in women, DCIS in the male breast has a good prognosis. Total mastectomy without axillary dissection is the basic treatment. Frequently, the first symptom is a bloody nipple discharge. The age of occurrence is younger than for infiltrating carcinoma, suggesting that DCIS is the first step in the development of breast cancer.

From 1960 to 1986, 397 cases of non-metastatic male breast cancer (MBC) treated in 14 French regional cancer centres were reviewed. The median age was 64 years (range 25-93). TNM classification (UICC, 1978) showed seven T0, 79 T1, 162 T2, 31 T3, 74 T4 and 44 unclassified tumours (Tx). Clinical positive lymph nodes were found in 31% of the patients. 24 patients received radiotherapy only, and 373 underwent surgery, 247 of these with postoperative irradiation. Adjuvant chemotherapy and hormonal therapy were used in 71 and 68 patients, respectively. There were 382 infiltrating carcinomas and 15 pure ductal carcinoma in situ. Lymph node involvement was found in 56% of infiltrating carcinoma. The oestrogen (ER) and progesterone (PgR) receptors were positive in 79% and 77%, respectively, of examined cases. Isolated local and regional recurrence were observed in 8.8% and 4.5% of cases, respectively and 40% of patients developed metastases. The crude survival rates by Kaplan-Meier method were 65% and 38% at 5 and 10 years, respectively, and the disease-specific survival rates (without death due to intercurrent disease or second cancer) was 74% at 5 years and 51% at 10 years. The disease-specific survival rate for pN- and pN+ groups were 77% and 39% at 10 years. The prognostic factors were clinical size (T) and histological axillary status (pN-/pN+). The relative risk of death for pN- was 1.0, 2.0 and 3.2 in the T0-T1, T2 and T3-T4 groups, respectively. For pN+, these relative risks increased 1.9, 3.9 and 6.0 in the same groups. The optimal treatment include modified radical mastectomy and irradiation for cases with risk factors of local relapse (nodal invasion, large tumour with cutaneous or muscular involvement). Locoregional failure had unfavourable prognosis. First-line adjuvant treatment seems to be tamoxifen, due to the very high rate of positive hormonal receptors and the old age of the patients, which contraindicate chemotherapy in many cases. The prognosis of patients with breast cancer is the same in male and female patients when disease-specific survival rate, tumour size and axillary involvement are compared.
