[Breast cancer in young patient in Morrocco]

OBJECTIVE

The aim of this retrospective study is to determine the epidemiological, clinical, therapeutic aspects and prognostic factors of breast cancer in women through a comparative study of 648 patients treated for breast cancer: 165 patients are at 35 years of age or less (G 1), 286 patients are more than 35 years old and non menopausal (G 2).

PATIENT AND METHOD

We have collected, for each group, the epidemioclinical data. Nonmetastatic and operable cancer was treated by surgery (conservative or radical) followed by an adjuvant treatment (chemotherapy, radiotherapy, hormomotherapy) that was indicated according to prognosis factors. Locally advanced forms or metastatic at the moment of diagnosis were treated firstly by chemotherapy.

RESULTS

T2N1 forms with lymph node involvement, high grade (SBR II, III) and negative hormonal receptors (HR-) were predominant. There was no difference between the two groups of women concerning risk factors or clinical criterias, except for the mammography that was more sensible in the second group.

CONCLUSION

The breast cancer in our young patient doesn't seem to be different from the older ones either in clinical presentation or evolution. The conclusions of different authors are divergent but they are all for evoluated forms with more defavorable prognosis than in the older women.

[Pure colloid carcinoma of the breast: anatomoclinical study of seven cases]

PURPOSE

Breast mucinous carcinoma is a particular histological form characterized by the extracellular production of mucus. The pure form is rarely reported and its prognostic is better than the other types of the breast cancer. The aim of the present study was to discuss the various anatomoclinical, therapeutic aspects and the prognostic factors of the pure mucinous carcinoma of the breast.

PATIENTS AND METHODS

We report seven cases diagnosed over a period of 11 years (1993-2003) in the laboratory of anatomy and pathological cytology of the university hospital of Sfax. A review of the clinical files with immunohistochemistry study (hormonal receptor, synaptophysine, chromogranine, Bcl2, Ki67, P53 and Her-2/neu (C-erbB-2)) were carried out for all the cases.

RESULTS

pure colloid carcinoma of the breast accounted for 0,5% of the whole of the breast cancers. The average age of patients was 69 years. At the time of the diagnosis, four tumours were classified T4, one T3, two T2, two N1 and one N3; no patient had presented metastasis (M0) according to pTNM classification. The echomammography showed regular contours mass in four cases. The anatomopathological study showed that the neuroendocrine differentiation was found in two cases, all the tumours had presented positivity for the hormonal receptors (oestrogen and progesterone) and negativity for the other antibodies, two cases exhibited the Bcl2 positivity and negativity for the other antibodies. An adjuvant radiotherapy was carried out for all the patients. The average duration of follow-up was of 33 months; the evolution was marked by the occurrence of metastases in two cases.

CONCLUSION

The pure colloid carcinoma of the breast constitutes a particular morphological entity which deserves to be individualized; neuroendocrine differentiation of these tumours must be required. Their forecast is relatively favourable.

Le cancer du sein de la femme jeune dans le sud tunisien

OBJECTIVE

The objective of this retrospective study was to discuss the epidemioclinical criteria, the therapeutic results and the prognostic factors of breast cancer in young women throughout a comparative study of 72 young patients aged less than 35 years and a second group of older premenopausal patients aged between 36 and 50 years.

PATIENTS AND METHODS

We reviewed the epidemioclinical records of all the patients. Non-metastatic and operable patients were treated with surgery (conservative or radical) followed by an adjuvant treatment (chemotherapy, radiotherapy, endocrine therapy) indicated according to the prognostic factors. Locally advanced or metastatic tumors were treated with chemotherapy. Overall survival was calculated according to the Kaplan-Meier method. The comparison of survival curves was performed according to log-rank test. The multivariate analysis was performed according to the Cox model.

RESULTS

The mean age was of 31.5 years. T2N1, node positive (N+), high grade (SBRII and III) and endocrine non-responsive tumors were the most frequent. There was no difference with the second group of older patients regarding the risk factors and the clinical criteria but mammography was more sensitive in the second group. The 5 years overall survival of young patients was of 57% and pejorative prognostic factors in univariate analysis were: tumor size, N+ and endocrine non-responsiveness. There were not any significant prognostic factors at the multivariate analysis. Young age less than 35 years was not a prognostic factor influencing overall survival in the totality of patients or in the different sub-groups according to the other prognostic factors.

CONCLUSION

Clinical presentation and outcome of breast cancer in our young patients aged under 35 years seems not to be different from that in older patients. The conclusions of the different authors are controversial but the majority has reported more advanced tumors with worse prognostic than those of older patients.
