[Factors determining the choice between mastectomy and conservative treatment in the Côte-d'Or department (France). The Côte-d'Op6 register of gynecological cancers].

The aim of this study is to check, for a defined period and within a geographic area, whether the increased use of breast conserving treatment was related to changes in tumor characteristics, or whether changes in therapeutical practice persisted after adjustment on patients and tumor characteristics. From 1982 to 1990, 1,952 women with invasive carcinomas were registered in the French "departement" of Côte-d'Or. Seventeen hundred and seven non metastatic patients were treated by loco-regional surgery. A breast conserving surgery was performed in 60% of cases. The incidence of this treatment raised from 32% in 1982 to 73% in 1987. In univariate analysis, factors determining the type of tumor excision were: age, hormonal status, tumor size, tumor location, "clinical seriousness", nodal status, multiple tumors, inflammatory tumors, neoadjuvant treatments and year of diagnosis. Age and tumoral factors remained significant in a logistic regression analysis. Other factors being constant, the odds ratios of mastectomy was 12.9 times lower in 1987-1990 than in 1982, and 2.1 times lower than in 1985-1986, showing a "period effect". Ninety four percent of patients treated by breast conserving surgery were irradiated post operatively, showing that the clinical research recommendations were well transferred to the clinical practice in this department.

[Cancer of the breast in Cote-d'Or (1982-1987). The Burgundian register of gynecologic diseases].

Burgundian registry of gynaecological pathology, formed in 1982 is involved in the study of epidemiologic and clinical features of breast cancer in the district of Côte-d'Or. One thousand two hundred and twenty nine new cases were recorded from 1982 to 1987. Crude incidence was 82.8/100,000 women. Age standardised incidence, based on world standard population was 63.4/100,000 women. Incidence of breast cancer was higher in urban areas (66.0/100,000 women) than in rural (55.0/100,000 women) areas. In comparison with data of other cancer registries, women from Côte-d'Or are in the high risk group. Histological diagnosis was reported in 97% of cases. The most frequent histologic types were infiltrating duct carcinoma (81.6%) and infiltrating lobular carcinoma (4.4%). Non-invasive carcinoma was present in 4.2% of cases; 4.8% of patients presented metastases at the time of primary diagnosis. Sixty four percent of tumors measured less than 30 mm (on gross specimen). Frequency of axillary nodal involvement was lower than 20% for tumors which measured less than 10 mm but increased up to 40% for larger tumors. From a therapeutic point of view, 91% of patients underwent mammary surgery, 67% underwent radiotherapy and 44% underwent chemotherapy and/or hormonotherapy. Five-year observed actuarial survival rate was 68%, corrected 75% and specific 77%. These results point out the necessity of extensive use of mammography for screening of small breast tumors which have a low risk of nodal involvement.

Actuarial Analysis↗

[Carcinoembryonic antigen in carcinoma of the uterine cervix. Correlations with clinical stage, histopathology, and survival about 115 cases (author's transl)].

Carcinoembryonic antigen is elevated in the serum of approximately 35% (35/98) of patients with carcinoma of the uterine cervix. The incidence of elevated serum CEA is not related to stage of disease, histopathology, lymphangiogram and survival rate. Carcinoembryonic antigen levels return to normal after curative radiation therapy (25/32). Persistently high values after irradiation are indicative of residual disease (3/32). Reappearance of CEA, with a progressive rise evoke a recurrence, and may precede the clinical diagnosis.

Carcinoembryonic Antigen↗

[Carcinoembryonic antigen in carcinoma of the uterine cervix (author's transl)].

The authors analyse 123 cases of carcinoma of the uterine cervix treated by radiotherapy, with CEA radio-immuno-assay performed before treatment then each time patients are seen in follow-up. The CEA level is positive in 35 per cent of the cases with a mean value of 21 per cent for stage I, 36 per cent for stage II and 48 per cent for stage III. CEA level become negative at the end of the treatment (80%) or after (100%) when there is a complete disappearance of the tumour. The persistence of a positive level is well correlated with the abscence of sterilization, and reappearance of CEA evokes a recurrence. Preliminary results do not seem to show a prognosis value of pre-therapeutic level of CEA according to survival rate at 2 years.

Preliminary results using twice-a-day fractionation in the radiotherapeutic management of advanced cancers of the head and neck.

Twenty-four cases of advanced T4 cancers of the head and neck were treated using a twice-a-day treatment fractionation delivering a 1,200 rad weekly tumor dose and 7,000 rad total tumor dose in 5 1/2-6 weeks. Acute normal mucosal reactions and skin reactions were plotted weekly and corresponded to reactions observed when delivering 1,000 rad per week in five treatment sessions. Chronic problems have been limited to severe neck fibrosis appearing in three of five patients who underwent a planned neck dissection 6 weeks after the completion of radiotherapy. Local control was observed in 14 of 23 patients (61%) and regional control in 22 of 23 patinets (96%).

[Prevention of caries and osteonecrosis through daily local fluoridation in radiotherapy patients].

The healthy dentition of 432 patients treated by radiotherapy for ENT and salivary gland lesions was preserved and subjected to a programme of strict hygiene and daily local fluoride application using a gel containing 1% of sodium fluoride. Effectiveness in terms of the prevention of caries was satisfactory. Caries developed in only 7% of the patients. None of the patients in whom there was a clear indication and who followed treatment carefully to an extent greater than 70% suffered decay. Thorough initial assessment, and very careful selection of cases should make it possible in the future to avoid the majority of sources of failure observed. The prevalence of osteo-necrosis secondary to dental preservation was 1.2%, identical to the prevalence of trophic complications seen in patients who underwent total extraction before radiotherapy. The technique of fluoride application is simple, with no risk of toxicity, but must be continued indefinitely. Preservation of the dentition must be undertaken only with the close cooperation of the responsible medical and odontological teams, the latter being responsible for the initial assessment, care and surveillance. Preservation of a healthy dentition together with the possibility of early fitting of a prosthesis if necessary contribute to the rapid functional rehabilitation of patients irradiated for malignant disease in the ENT area.

[Technical record in radiotherapy (author's transl)].

The term "technical record in radiotherapy" is used to describe collected information relative to treatment using radiation. The subject of this session of the chapter of Radiotherapy of the Société Française de Radiologie was the intrinsic functions of this record and its extrinsic limitations. The extreme diversity of the current state of the record is a known fact. A majority of participants express the desire for uniformisation of the collection of data or even, as a second stage, to have a common record. A library of technical records was set up under the responsibility of the Centre Georges-François Leclerc at Dijon (J.C. Horiot). One broad conclusion was seen to emerge: the creation of a minimum common record including essential information to which could be added the more specific data of each radiotherapist and at each time of use. Prior agreement will be necessary with regard to the standardisation of apparatus and the expression of the dose. This session was of necessity merely a reflection of future needs and it is to be hoped that the good will which was obvious during the course of the discussion may produce concrete results in the months to come.
