RESUMO

PURPOSE: Gene fusions that result from the chromosome translocations observed in Ewing's tumor (ET) provide tumor-specific markers that can be used to detect the presence of tumor cells in peripheral blood (PB), bone marrow (BM), and stem cell collection (SCC). These markers were used to evaluate, at diagnosis, a series of 67 ET patients. PATIENTS AND METHODS: RNA was extracted from nucleated cells from PB and BM and a nested reverse-transcriptase polymerase chain reaction (RT-PCR) was performed to search for EWS-FLI-1 or EWS-ERG fusion transcripts that resulted from the t(11;22) or t(21;22) translocations, respectively. RESULTS: At diagnosis, 16 of 62 (26%) patients had circulating tumor cells. This was not correlated with any clinical parameter. In contrast, Ewing's cells were detected by RT-PCR in BM in 14 of 43 (33%) patients and were associated with the presence of clinically detectable metastases and a statistically significant unfavorable outcome in univariate analysis. There was no correlation between the RT-PCR results in PB and in BM. CONCLUSION: These results suggested that the monitoring of BM but not of PB by RT-PCR might constitute an important criterion for the staging, at diagnosis, of patients with ET. Further studies should appreciate the relationship or independence of this marker toward other classical prognostic factors in ET, particularly to the presence of clinically detectable metastases.

RESUMO

The prevalence of alcohol use disorders in hospital patients was studied in all the hospitals of one area of France. Alcohol disorders were diagnosed by the head nurse or a physician in the hospital where the patient was being attended, and by means of the CAGE self-questionnaire. This descriptive survey, carried out on one particular day, concerned 7626 patients. The prevalence of alcohol disorders was 18%, whereas only 6% of the admissions were for alcohol-related pathologies. Prevalences were 25% in men and 7% in women, 10% in persons aged under 25 years and 43% in men aged between 36 and 55 years. In all, one patient in two was diagnosed directly, though only one in four in the age range under 25 years. These results suggest that too few patients with alcohol use disorders are identified in hospitals, especially in certain age groups and certain types of ward.

RESUMO

Fertility after ectopic pregnancy (EP) was investigated in a non-selected population taking into account intrauterine device (IUD) use at the time of the EP. Between January 1992 and June 1996, 647 women listed in the EP register of Auvergne (France) were followed up. The analysis included only the 328 women who were seeking to become pregnant: 23 women using IUD at the time of the index EP (IUD users) and 305 IUD non-users. Among IUD users, there was no recurrence of EP, and the 1 year cumulative rate was 87% [95% confidence interval (CI): 73-100%] for intrauterine pregnancies and 86% (95% CI: 72-100%) for deliveries. Among IUD non-users, the 2 year cumulative rate for recurrence of EP was 28% (95% CI: 17-39%), and the 1 year cumulative rates were 60% (95% CI: 53-66%) for intrauterine pregnancies and 44% (95% CI: 38-56%) for deliveries. The adjusted intrauterine pregnancy rate of IUD users was not significantly different from that of IUD non-users. However, IUD non-users had more miscarriages, so their delivery rate was lower.

RESUMO

The expression of estrogen (ER) and progesterone (PgR) receptors was analyzed in a retrospective series of 3000 patients who had operable primary breast cancer. Patients were stratified according to ER and PgR status and the study was focused on the two groups (ER-PgR+ and ER-PgR-) of patients whose tumors contained low levels of ER (< 15 fmol/mg protein), regarding potential response to endocrine therapy. The comparison of clinical or histological characteristics between ER-PgR+ and ER-PgR- patients was analyzed as well as the disease-related death and survival. The mean follow-up was 86.3 months. Among the 529 ER-patients, 62 were PgR+ (12%), whereas 467 were PgR- (88%). The ER-PgR+ and ER-PgR- populations represented 2% and 15.6% of the overall population, respectively. In ER- tumors, the PgR status was significantly related to: age, menopausal status, tumor size, SBR grade, and histological type, but not to the type of surgical treatment or to lymph node involvement. ER-PgR+ tumors had smaller size (64% T1 vs 43%) (p=0.004) and were more frequently grade I (28% vs 12%) than ER-PgR- tumors (p < 0.001). In addition, the patients with ER-PgR+ tumors were significantly younger (49.4 years vs 58.4 years; p < 0.0001), and were more frequently premenopausal (76% vs 36%, p < 0.001). The disease-free interval and the metastasis-free survival tended to be worse for ER-PgR- than for ER-PgR+ patients, but the difference was not statistically significant at 10 years. However, a small but significant difference in overall survival, in favor of the PgR+ group, was observed between the two groups during the first 5 years (p=0.03). We conclude that in combination with ER, PgR status defines a group of patients with clinical and biological specificity, which could be considered for specific endocrine therapy.

RESUMO

To document whether c-erbB-2 over-expression or p53 accumulation in tumour cells was predictive of response to chemo- or radiotherapy, we analyzed a population of patients with breast cancer assigned to neo-adjuvant therapy (median follow-up: 54 months). T2/T3-N0N1b-M0 tumours (329 cases) were treated either by FAC chemotherapy or by radiotherapy before surgery, and the clinical response was classified as complete or incomplete. Expression of c-erbB-2 and p53 was retrospectively evaluated by immunohistochemistry. Proliferation rate was assessed by means of MIB-1 antibody and by S-phase fraction. A complete response to chemotherapy was observed in 38/167 patients (23%). Complete response rate was 20% in c-erbB-2-negative tumours, and rose to 31% in tumours with c-erbB-2 over-expression, but this trend was not statistically significant. There was no correlation between p53 staining and response to treatment, whereas chemosensitivity was found correlated with histological grade and S-phase. A complete response to radiotherapy was observed in 64 of the 156 evaluable patients (41%). Complete response rate was 41% in c-erbB-2- or p53-negative tumours, 54% in tumours with c-erb-B-2 over-expression, and 44% in tumours with p53 accumulation. There was no correlation between response to radiotherapy and histological grade or proliferative rate. No prognostic value was found for c-erbB-2 or p53 expression, whereas the 5-year survival rate was 85% for patients presenting a tumour with a low proliferating index (MIB-1 < 10%), and 68% for patients presenting a tumour with a high proliferative index. In multivariate analysis, node status (RR = 2), MIB-1 immunostaining (RR = 2), and tumour size (RR = 1.8) were found to be associated with survival. These results indicate that c-erbB-2 or p53 expression is not significantly associated with tumour response to neo-adjuvant chemo/radiotherapy in our series of breast cancers.
