RESUMEN
Between January 1977 and December 1982, 66 consecutive patients have been treated for unilateral, rapidly progressing, non metastatic breast cancer. They were divided into three groups: Group A (n = 10): tumor whom volume had increased during the 2 months before diagnosis; Group B (n = 30): inflammatory signs (erythema, skin oedema, elevated local temperature) involving less than one half of the breast; Group C (n = 26): inflammatory signs involving more than one half of the breast. All patients where managed similarly: 3 to 4 courses of chemotherapy (CMF: n = 24; AVCF: n = 42), then loco regional irradiation therapy with cobalt 60, followed by maintenance chemotherapy, only if the first chemotherapy had proved effective (CMF: n = 13; AVCF: n = 27). Nine patients with residual tumor after radiotherapy underwent mastectomy with axillary dissection. The actuarial 5 years survival for the whole group is 29%, and respectively 49%, 38% and 9% for the groups A, B and C. The median disease free intervals are 43, 29 and 12 months respectively. Fifteen prognostic factors likely to influence overall survival or disease free survival were evaluated. With univariate analysis, 8 factors were found to be of individual prognostic value: extent of initial erythema, erythema present after initial chemotherapy, erythema present after radiotherapy, non menopaused status, tumor diameter greater than 10 cms, residual breast tumor (clinical or radiographic) after maintenance chemotherapy, supra clavicular adenopathy (N3). Age at the diagnosis, type of chemotherapy, or performance of a radical mastectomy did not influence the prognosis. Multivariate analysis using the Cox-model isolated 3 factors of bad prognosis: erythema involving the whole breast at initial diagnosis, erythema present at the end of initial chemotherapy, N3.

The beneficial effects of circulatory reversal by lateral a.-v. fistula was confirmed in 20 hind limbs of dogs made ischaemic by Collagen embolisation. Although not done in the experiments presented here, rupture of the distal venous valves is advisable. The peripheral circulation was studied by measurement of venous pressures and by angiography. Retrograde infusions, with proximal tourniquet, confirmed reversal of flow veins to arteries. Return routes to the heart remain unknown.

The authors reviewed the case files of 49 adult patients undergoing splenectomy for chronic idiopathic thrombocytopenic purpura at the Centre Henri Becquerel between 1970 and 1987. Although the postoperative course was straightforward in 83.7% of cases, one reoperation for subphrenic abscess was necessary and there was one postoperative death. Remission from thrombocytopenia was obtained in 87.5% of the patients, but only transiently in 8.5% of them. No preoperative predictive factors could be demonstrated. An early postoperative rise in the platelet count to more than 500 G/litre appears to ensure a good subsequent result. Secondary infectious complications are not exceptional and can be fatal (one death in our series); they require prophylaxis by anti-pneumococcal vaccination. The place of prophylactic antibiotic therapy has yet to be defined.

15 stellar types breast lesions were reviewed and classified according their etiology (fibrosing adenosis, dysplasia, dystrophy, radial scar of Aschoff, fat necrosis). Radio-anatomical confrontation allowed to understand the images given by the varying appearances of the connective skeleton surrounded by adipose lobules. The authors study the diagnosis of the stellar breast lesions and recall the determinant role of connective tissue in the genesis of mammographic stellar images.

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.

The t(14;18)(q32;q21) chromosomal translocation is observed in more than 75% of cases of follicular lymphoma. Several additional chromosomal abnormalities, which might contribute to tumor progression, have also been described. However, prognostic implications of cytogenetic features in follicular lymphoma have not been clearly established. In an attempt to correlate cytogenetic findings with clinical outcome, we have studied survival and risk of transformation into a more aggressive lymphoma in 66 follicular lymphoma patients from whom a lymph node had been karyotyped at the time of diagnosis. A t(14;18) was the most common abnormality, having been observed in 51 patients (77%), but this showed no correlation with clinical outcome. Seventeen other recurrent numerical or structural abnormalities were identified in more than 10% of the patients. A high percentage of cells (> or = 90%) with abnormal metaphases and a number of chromosomal breaks higher than 6 were associated with a poor survival (P > .01 each). Patients with an abnormality of chromosome region 1p21-22 (P < .01), of 6q23-26 (P < .001), or of the short arm of chromosome 17 (P < .001) had a significantly shorter survival in univariate analysis. Multivariate analysis identified a break at 6q23-26 (P = .01) and 17p (P = .01) as independent prognostic factors in this population. The risk of transformation into a diffuse large-cell lymphoma was significantly higher in patients with either a 6q23-26 (P < .001) or a 17p (P < .01) abnormality. Chromosomal analysis of follicular lymphoma at the time of diagnosis can thus provide important information about the risk of transformation and survival.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a series of 20 non-Hodgkin's lymphomas (NHL) in which cytogenetic analysis showed a translocation involving band 3q27 and the site of one of the three Ig genes (14q32, 2p12, 22q11) in the neoplastic cells. These cases were found in a series of 319 patients with clonal chromosomal abnormalities studied over a 7-year period. Fourteen patients had diffuse lymphoma, mainly of large cell type and the remaining six were follicular lymphomas. All cases studied were of B-cell phenotype. A t(3;14)(q27;q32) was commonest, found in 15 patients (4.7%), with the two variant translocations, t(3;22)(q27;q11) and t(2;3)(p12;q27), being found in three and two patients, respectively. Additional chromosomal defects were present in most patients, but two patients had this type of translocation as the sole abnormality. These results indicate that translocations involving band 3q27 and Ig genes are not uncommon, and suggest that a novel oncogene, located at band 3q27, may be implicated in B-cell NHL.

During surgery for carcinoma of the oesophagus, the authors emphasise the need for selective intubation using a Carlens tube, of avoiding damage to the diaphragm and the phrenic nerve at all levels, and of draining the hemithorax involved in the operation by three drains: anterior and posterior thoracic and madiastino-abdominal. These precautions reduce post-operative difficulties, justifiy excision surgery for carcinoma of the oesophagus, and to a certain extent make it possible to reduce the contraindications, in particular in the presence of tracheo-bronchial spread. Amongst 107 patients undergoing surgery, in whom there was a risk of respiratory insufficiency in one quarter, surgery (sometimes with extension of the excision: one case in four) was associated with an operative and post-operative mortality of 18%.

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.
