The treatment of breast cancer in a French anticancer centre.

The complete protocol for the treatment of breast cancer at the Institute Gustave Roussy, Villejuif, France, is presented. Treatment is carried out by a multidisciplinary committee dealing with nearly one thousand new breast cancers annually. The protocol is based on initial classification by the T.N.M. system and by characteristics indicating "aggressive biological behaviour". Patients are separated into three broad groups for which the mainstays of treatment are surgery, radiotherapy, and chemotherapy. The rationale and results of the protocol are presented.

[Clinical prognostic factors in breast cancer].

Five year survival of 683 mammary carcinomas would confirm the prognostic value of T.N.M. classification (UICC), of tumor particular characteristics (size, fixation to neighbouring structures) and presence or absence of clinical nodes. A clinical-histological relationship was studied for axillary nodes: in our experience, clinical determination is more reliable for estimation of N0 and N2 than N1. Three groups of age were considered; the age, T and N corrected five year survival show a higher mortality for patients older than 60 years with T3-T4, N greater than 0 carcinomas. The study of this prospective computerised register confirms the prognostic value of developping growth tumors (PEV) described by P. Denoix. In fact, inflammatory carcinomas (PEV 2-PEV 3) show a poor 5 year survival and PEV 1 is an intermediate pronostic group between stable and inflammatory carcinomas. PEV 1 was showed to be an independant clinical factor from T and N characteristics.

[Radical mastectomy and modified radical mastectomy in the treatment of breast cancer. Indications and results].

We studied first the long term results in a series of 1 139 immediately operable breast cancers, treated by a protocol which gave an important role to extended radical mastectomy (radical mastectomy with internal mammary node dissection). No difference in survival was noted according to the surgical procedure used, and the extended mastectomy does not seem to have demonstrated its superiority. Its value could be judged in a more rigorous manner thanks to the results of an international therapeutic trial, comparing radical mastectomy with extended radical mastectomy. Results were improved by the extended procedure in only one sub-group of patients, whose tumours was located in central or inner quadrants, T1 or T2, with positive axillary nodes: these patients represents 13 per cent of patients with immediately operable tumors. Taking these results into account a new protocol has been adopted at the Institut Gustave-Roussy: T1 cancers will be the object of a therapeutic trial between conservative treatment and modified radical mastectomy. T2 (internal or central) cancers, with axillary nodal involvement will be treated by extended radical mastectomy. T2 tumors (external) and all T3 tumors will be treated by a modified radical mastectomy.

Wilms' tumor: natural history and prognostic factors: a retrospective study of 248 cases treated at the Institut Gustave-Roussy 1952-1967.

A statistical analysis of 248 histologically proven cases of Wilms' tumor treated at the Institut Gustave-Roussy, Villejuif, France, from 1952 to 1967, is presented. Two years recurrence-free survival and five years survival have been selected as prognostic criteria. Patients under two years of age have significantly fewer metastases and a better five-year survival rate than those over two. Stage is stronly correlated with recurrences and survival. Influence of tumor size, number of tumor nodules, tumor rupture, adhesions, regional lymph node involvement, and renal vein infiltration is shown. Detailed analysis of histopathologic features indicates that a favorable clinical course is significantly related to the number of different varieties of epithelial differentiation (tubular, glomerular, microcystic) found in any tumor, whatever the abundance of each of them. Presence of striated muscular cells, however abundant, does not influence survival or metastatic rates. Cases where irradiation given prior to surgery resulted in complete destruction of tumor cells, form a distinctive group of very unfavorable prognosis. Relapse of tumor occurs in 54% of cases, 10% presenting with metastases. Involved sites are listed. No correlation is found between date of metastases and other parameters. The three major prognostic factors of age, stage, histologic pattern, bear prognostic value separately. Stage and age are linked, as well as histology and age. Stage and histology are not linked. Age in itself therefore seems less important. It is concluded that these well-defining treatment for each individual case.

Radiation enteritis in children. A retrospective review, clinicopathologic correlation, and dietary management.

The clinicopathologic features of radiation enteritis are reviewed in 44 children receiving whole abdominal radiation therapy between 1961-1972 at the Institut Gustave-Roussy. Five of 14 long-term survivors (36%) developed severe delayed radiation injury with small bowel obstruction, occurring within 2 months after completion of irradiation. All had previously had acute radiation reaction during therapy. Histologic appearance in the small bowel at the time of delayed radiation injury revealed severe villus blunting, lymphatic dilatation, and moderately dense inflammatory infiltrate. All patients with delayed radiation injury showed marked clinical improvement coincident with a fractionated low-residue, low-fat diet, free of gluten and free of milk and milk products. The abnormal small bowel roentgenographs and small bowel biopsies reverted to a normal appearance in association with the diet. No exacerbation of radiation enteritis has been seen following dietary therapy.
