RESUMEN

Margin status is regarded as a major prognostic factor for local recurrence after breast conservative treatment. Margin definition in the literature is not always clear and precise. The impact on the therapeutic management may be quite different. This paper presents the radiotherapeutic attitude according to a survey realized in the twenty French cancer centers. The surgical practice in terms of margins status is appraised. The radiotherapist attitude in terms of boost's modulation is specified.

RESUMEN

PURPOSE: To assess the clinical and histological characteristics of breast cancer (BC) occurring after Hodgkin's disease (HD) and give possible therapies and prevention methods. MATERIALS AND METHODS: In a retrospective multicentric analysis, 117 women and two men treated for HD subsequently developed 133 BCs. The median age at diagnosis of HD was 24 years. The HD stages were stage I in 25 cases (21%), stage II in 70 cases (59%), stage III in 13 cases (11%), stage IV in six cases (5%) and not specified in five cases (4%). Radiotherapy (RT) was used alone in 74 patients (63%) and combined modalities with chemotherapy (CT) was used in 43 patients (37%). RESULTS: BC occurred after a median interval of 16 years. TNM classification (UICC, 1978) showed 15 T0 (11.3%), 44 T1 (33.1%), 36 T2 (27.1%), nine T3 (6.7%), 15 T4 (11.3%) and 14 Tx (10.5%). Ductal infiltrating carcinoma and ductal carcinoma in situ (DCIS) represented 81.2 and 11.3% of the cases, respectively. Among the infiltrating carcinoma, the axillary involvement rate was 50%. Seventy-four tumours were treated by mastectomy without (67) or with (ten) RT. Forty-four tumours had lumpectomy without (12) or with (32) RT. Another four received RT alone, and one CT alone. Sixteen patients (12%) developed isolated local recurrence. Thirty-nine patients (31.7%) developed metastases and 34 died; 38 are in complete remission whereas five died of intercurrent disease. The 5-year disease-specific survival rate was 65.1%. The 5-year disease-specific survival rates for the pN0, pN1-3 and pN>3 groups were 91, 66 and 15%, respectively (P<0.0001), and 100, 88, and 64% for the TIS, T1 and T2. For the T3 and T4, the survival rates decreased sharply to 32 and 23%, respectively. These secondary BC are 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 spreading' such as DCIS and microinvasive lesions. These lesions developed especially in patients treated exclusively by RT. CONCLUSIONS: The young women and girls treated for HD should be carefully monitored in the long-term by clinical examination, mammography and ultrasonography. We suggest that a baseline mammography is performed 5-8 years after supradiaphragmatic irradiation (complete mantle or involved field) in patients who were treated before 30 years of age. Subsequent mammographies should be performed every 2 years or each year, depending on the characteristics of the breast tissue (e.g. density) and especially in the case of an association with other BC risk factors. This screening seems of importance due to excellent prognosis in our T(1S)T(1) groups, and the possibility of offering these young women a conservative treatment.

RESUMEN

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.

RESUMEN

PURPOSE: Though Hodgkin's disease (HD) is one of the malignancies in which considerable progress has been made, long-term side effects have been observed, second primary cancer being the most significant. Several recent reports have indicated an increased risk of breast cancer (BC) in girls and young women among HD patients. MATERIALS AND METHODS: In a retrospective multicenter analysis, 63 women treated for HD subsequently developed BC. Results that were obtained in 13 women (21%) who developed either synchronous (five cases) or metachronous (eight cases) BC were analyzed. The median age at diagnosis of HD was 19 years. Seven patients underwent exclusive radiotherapy (RT) (including "mantle" supradiaphragmatic irradiation) and six received concomittant radiation therapy and chemotherapy. RESULTS: The first breast tumor occurred after a median delay of 16 years. According to the TNM classification, we showed nine stage T0 (non palpable lesions), four stage T1, five stage T2, one stage T3, two stage T4 and five stage Tx BC. Seventeen infiltrating carcinomas, two fibrosarcomas and seven ductal carcinomas in situ were observed. Among 15 axillary dissections performed for invasive carcinomas, histological involvement was found in 10 cases. Seventeen tumors were treated by mastectomy and nine patients underwent conservative surgical treatment. With a 70-month median follow-up (range: 15-125), three patients developed locoregional recurrence and four other metastases. At present, eight are alive with no evidence of disease and one died of intercurrent disease. CONCLUSION: According to previous works, BC represents 6.3 to 9% of all second cancers occurring after HD treatment. The risk is higher in young women treated before 20 years of age, especially before 15 years of age. Factors that favour the development of secondary BC are: supradiaphragmatic irradiation, very young age at treatment, chemotherapy with alkylating agents, and probably genetic factors. We conclude that young women and girls treated for HD should be carefully monitored at least 10 years after the end of the treatment for HD, using clinical examination, mammography and ultrasonography. The optimal rythm of this follow-up is not yet clearly defined. Moreover, after multidisciplinary concertation, we suggest that secondary BC be sometimes treated by conservative radiosurgical approach.

RESUMEN

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.

RESUMEN

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.

RESUMEN

This retrospective study shows the advantage of the CA 15.3 assay for the early detection of relapse in breast cancer. It involved 473 women with invasive canalar carcinoma who had local recurrence or metastasis and/or an elevation of CA 15.3 (> 35 kU/l). The positive predictive value is excellent (97.7%). Sensitivity is poor for local relapse (13.7%), but a marker elevation at this time is a good prognostic factor of further distant metastasis (88%). It is better in the case of distant metastasis (74%), especially in bone and and liver localizations. CA 15.3 measurement at two month intervals may allow an early detection in 40% of distant metastasis. These results confirm the need of trials to test the benefits in terms of survival of early treatment of breast cancer metastasis only proved by CA 15.3 elevation, without any clinical or radiological finding.

RESUMEN

One hundred and seventy-eight patients with non metastatic inflammatory breast cancer (IBC) have been treated at the Centre H. Becquerel. Median follow up is 67 months (6-178). Every patient received neoadjuvant chemotherapy (mean number of cycles = 4; range: 2-8), followed by a loco regional treatment (radiotherapy = XRT or modified radical mastectomy = S), followed by adjuvant chemotherapy. During this period, the types of chemotherapy and locoregional treatment have been the following: Study I: 64 patients treated with CMF or AVCF and XRT; Study II: 83 patients, treated with either AVCF, FAC or VAC followed by S (n = 38) or XRT (n = 22) in case of complete or partial response, or followed by XRT (23) in case of initial supraclavicular lymph node involvement or lack of response after chemotherapy; Study III: 31 patients treated with FEC-HD + Estrogenic recruitment followed by S and XRT after adjuvant chemotherapy, except seven patients who received XRT (refusal of surgery). Although objective response rates (= 56.2, 73.5 and 93.5% for study I, II and III respectively) are statistically better in the 3rd study, this does not translate in dramatically different disease free survival (median = 16.7, 19 and 22.2 months respectively for study I, II and III) or overall survival (median = 25, 45.7 and 32.6 months respectively for study I, II and III). Analysis of subset of patients without supra clavicular lymph node involvement where neoadjuvant chemotherapy obtained at least a 50% response reveals a median disease free survival and median overall survival of respectively 38.3 and 60.1 months for patients who underwent S vs 19 and 38.3 months for those who received XRT (P = 0.15). These studies suggest that surgery has no deleterious effect on outcome of IBC. Advantage on disease free survival or overall survival from intensive chemotherapy in IBC remains to be proven with appropriate randomised trials.

RESUMEN

Male breast cancer represents about only 1% of all breast cancers. We have analysed a retrospective, multicentric series of 404 patients, initially non-metastatic, with mean age of 63 years. The 5 and 10-year overall survival rates were 65 and 36% respectively. Sixty-eight patients developed secondary cancer. From ten patients who already presented with cancer (2.5%) 3 cases corresponded to prostatic cancer treated by estrogen. Four had synchronous cancer (1%). Three and eight patients respectively had a synchronous and metachronous contralateral breast cancer (2.7% of bilateral cancer). Forty-three other patients (10.6%) developed metachronous cancer. The main tumor types were: prostate (9), lung (6), colon and rectum (6), esophagus (4). Four patients developed various hematologic malignancies and 14 patients, various types of solid tumors. From these 43 patients, 27 died; 19 as a result of secondary cancer. This represents 9% of all deaths among the 404 patients. While the bilateral cancer rate is similar to women, the second cancer rate appears to be higher in men. From hematological malignancies, chemotherapy and radiotherapy do not seem to contribute to this high incidence of second cancer.

RESUMEN

Ductal carcinoma in situ of the breast is very rare in men, representing 0-7% of all male breast cancers. We analysed 15 cases from a retrospective multicentric series of 404 patients (3.7%). It occurs earlier than infiltrating carcinoma (mean age: 55 years), sometimes before 40 years of age. The main symptoms are bloody nipple discharge or retro areolar mass. Modified radical mastectomy constitutes the basic treatment. Lower axillary dissection can eventually be indicated in comedocarcinoma or in tumors larger than 25 mm. The main histologic subgroup is papillary carcinoma, pure or intracystic. As is the case in women, local recurrence, invasive or not, rarely occurs. Theoretically, the cure rate approaches 100%. However, as in all cases of breast cancer in men, an important number of deaths due to secondary cancer or intercurrent disease have been noted. Until now, no clear etiologic factors have been found.

RESUMEN

Between October 1977 and December 1983, 379 consecutive patients have been treated for unilateral, non metastatic breast cancer, either with conservative (n = 205) or radical surgery (n = 174), with axillary dissection in all the cases. None of them had histologically proved lymph node involvement. Adjuvant radiotherapy was given in 268 cases. Estrogen receptor (ER) and progesterone receptor (PR) levels were measured on each tumor. Levels greater than 5 fmoles/mg cytosolic protein were considered as positive for both ER and PR. At 5 years, overall survival (OS) and disease-free survival (DFS) are respectively 88% and 79%. Unifactorial analysis using KAPLAN and MEIER estimates and Logrank test revealed that OS was significantly related to age, tumor size, histopathological grading, ER and PR. DFS was significantly related to the same factors. Menopausal status, number of intra mammary tumor foci, previous familial history of breast cancer were not significant. Multifactorial analysis revealed that DFS was significantly related to age (bad prognosis [bp]: less than or equal to 37 years old), tumor size, histopathological grading (bp: SBR = 3) and that OS was significantly related to tumor size and PR (bp: PR less than or equal to 5 fmoles/mg protein). A prognostic score was obtained which sampled our patients into 3 significantly different (P less than 0.0001) groups with high, intermediate and low risk of relapse. These results suggest that tumor size, histopathological grading and PR have their own prognostic weight in histologically node negative breast cancer. Grouping these factors together allows to define a high risk relapse group that could benefit from adjuvant treatment.

RESUMEN

From October 1977 to December 1983, estrogen receptor (ER) and progesterone receptor (PR) levels were measured in 645 tumors from women with primary, unilateral, nonmetastatic breast cancer. All of them were treated surgically. Some received adjuvant radiotherapy, adjuvant chemotherapy, or adjuvant hormonotherapy. A level of greater than 5 fmol/mg cytosolic protein was considered as positive for both ER and PR. Unifactorial analysis, using Kaplan and Meier estimates and the log-rank test, revealed that disease-free survival (DFS) and overall survival (SV) were both strongly related to age, tumor size, nodal status, nodal effraction, histopathologic grading (SBR), ER, and PR. Menopausal status and number of intramammary tumor foci were not significant. Multifactorial analysis, using Cox's model, revealed a strong relationship between SV and age (poor prognosis [pp]: less than or equal to 37 years old), menopausal status (pp: postmenopausal) tumor size, nodal status (pp: N+ greater than 3), nodal effraction, ER (pp: less than or equal to 5 fmol/mg), histopathologic grading (pp: SBR = 3), and PR (pp: less than or equal to 5 fmol/mg). Similarly, multifactorial analysis revealed a strong correlation between DFS and age, tumor size, nodal status, nodal effraction, histopathologic grading, and PR. A prognostic score taking into account these prognostic factors was calculated for DFS and SV. Analysis of this score allowed us to divide our patients into four significantly different (P less than 0.0001) groups with high, intermediate, and low risk of relapse. Our procedure was then validated using the sample test technique. These results show that both ER and PR have their own prognostic weight and should be considered, among other classic prognostic factors, when adjuvant therapies are indicated after surgical treatment of breast cancer.

RESUMEN

This study concerns 645 patients first treated with surgery for unilateral, non metastatic, invading breast cancer. Intratumoral estrogen receptor and progesterone level were determined in every case. Level greater than 5 fmoles/mg cytosolic protein was considered as positive for both receptors. Univariate analysis has pointed out a significant linkage between overall survival and the following factors: age, clinical size of the tumor, histopathological grading SBR, clinical and histological lymph node involvement, capsular tear, RO and RP status. Statistical significance of menopausal status is borderline. Number of tumor foci is not significant. Likewise, disease free survival was correlated to the same factors. Multivariate analysis (Cox), secondarily pointed out that overall survival was strongly related to age, size of the tumor, lymph node involvement, capsular tear, histopathological grading SBR, menopausal status and RP. Multivariate analysis of the disease free survival revealed that it was strongly related to age, tumor size, lymph node involvement, capsular tear, grading SBR and RP. An interaction has been pointed out between Ro and menopausal status: Ro greater than 5 fmoles/mg cytosolic protein carry its own prognostic weight (Cox) and lengthen overall survival only for post menopausal women. A prognostic score, taking into account all of these factors has been calculated for both overall survival and disease free survival, and enabled us to isolate 4 groups of patients with good, intermediate and bad prognosis. These 2 models have been validated on an independent group of patients according to the sample test procedure. This results indicate that hormonal receptors carry their own prognostic weight in operable breast cancer (only for postmenopausal women for RO), and should be taken into account when adjuvant therapies are indicated after surgical treatment for breast cancer, in association with other more usual prognostic factors.

RESUMEN

Between January 1977 and June 1983, 64 consecutive patients were treated for unilateral inflammatory nonmetastatic breast cancer. Our protocol included three or four courses of induction chemotherapy, then locoregional irradiation therapy with Co-60, followed by maintenance chemotherapy only if induction chemotherapy had proven effective. Eight patients with a residual tumor after radiotherapy underwent a modified radical mastectomy. Actuarial 3-year overall survival for the whole group was 38%, and the median disease-free survival time was 19 months. The effect of 17 factors on overall survival or disease-free survival was analyzed. With univariate analysis, eight factors were found to affect overall survival or disease-free survival: extent of initial erythema, size of initial edema, lymph node involvement, erythema present at the end of initial chemotherapy, erythema present at the end of radiotherapy, tumor size at the end of induction chemotherapy, residual breast tumor at the end of maintenance chemotherapy, and performance of a radical mastectomy. Age at diagnosis, menopausal status, type of chemotherapy, and date of appearance of inflammatory signs did not influence prognosis. Multivariate analysis using the Cox proportional hazard model isolated three bad prognosis factors: erythema involving the whole breast at initial diagnosis, erythema present at the end of initial chemotherapy, and lymph node involvement.

RESUMEN

The so-called inflammatory carcinoma of the breast is a rare condition characterized, in almost every case, by metastatic diffusion in numerous organs. Clinical criteria are indispensable to establish a diagnosis which is not ruled out by a negative skin biopsy. Radiotherapy or surgery, or both, gives disappointing results with a median survival of about 18 months and a 5-year survival rate of 5%. It is unanimously agreed that adding chemotherapy to these methods improves local control and increases the 5-year survival rate. The optimal treatment remains to be determined by co-operative studies.

RESUMEN

Between May 1978 and March 1982, 179 postmenopausal women with operable breast cancer were randomized to receive either adjuvant tamoxifen, 40 mg daily for three years (TAM group), or no further treatment (controls). The difference in five-year survival rates (61% in the control group, 72% in the TAM group) was not statistically significant. However, there was a significant improvement in disease-free survival in the TAM group (61%) relative to the controls (44%) (p = 0.008). In estrogen receptor positive patients, tamoxifen improved both the disease-free rate (47% controls, 80% with tamoxifen) and the survival rate (63% to 83%). Similar results were observed in progesterone receptor positive patients. In patients that were estrogen receptor negative, tamoxifen modified neither the survival rate nor the disease-free interval.

RESUMEN

The diagnostic value of mammography was evaluated retrospectively in 23 recurrent carcinomas in patients previously treated by partial mastectomy with or without adjuvant radiotherapy. Mammography established accurate diagnosis in 11 of the 23 patients. Mammography should always be performed in addition to clinical and cytological examinations and results must be evaluated jointly. Confrontation of these three investigations may be inconclusive as a result of changes produced by radiotherapy or surgery. The authors recall the necessity of surgical control of any nodular lesion developed in the area of the initial operation, particularly during the first three years.

RESUMEN

Diagnosis is suggested by the functional symptoms and digital rectal examination and must be confirmed by histological examination. The second step is to evaluate the patient's condition, the extent of the cancer and the consequences on the urinary system; the choice of the treatment depends on this evaluation. The most common tumors are adenocarcinomas with a histological grading strongly correlated to the lymphatic involvement and frequency of metastases. Lymphatic involvement is closely related to the local clinically demonstrable involvement, histological grade, serum acid phosphatase concentrations and results of lymphography. Upon diagnosis of cancer of the prostate more than half the patients already harbour metastases, usually of the bone. This percentage is correlated to the size of the primary tumor, involvement of the seminal vesicles, histological grade and lymphatic involvement. The authors propose a series of investigations adapted to each case.
