[Breast cancer and pregnancy: about 15 cases collected at the maternity center Monastir, Tunisia]. / Cancer du sein et grossesse: à propos de 15 cas colligés au centre de maternité de Monastir, Tunisie.

The purpose of this study was to describe the clinical, radiological, histological and therapeutic features of breast cancer diagnosed during pregnancy. We performed a review of all medical records of patients with breast cancer diagnosed during pregnancy in the Maternity and Neonatal Center, Monastir-Tunisia, over the period 2004-2019. We collected data on 15 cases. The average age of patients was 34 years; most pregnancy-associated breast cancers (PABCs) had been diagnosed during the postpartum period. Invasive ductal carcinoma was the major histological type (93% of cases), a rare case of secretory breast carcinoma had been observed. The main clinical stages were T2 and T4 breast cancer. Hormone receptor (HR)-negative breast cancers had been reported in 40% of cases, HER2-positive breast cancers in 26.6% of cases. Treatment included surgery, radiotherapy, chemotherapy and palliative chemotherapy. The median overall survival was 32.2 months. Pregnancy-associated breast cancer is a rare entity. Patients' prognosis is generally poor due to the young age at onset and a usually delayed diagnosis. Patients should participate in therapeutic decision making, which is difficult and multidisciplinary. Targeted therapy is the great hope for new therapies.

[Breast cancer treated with primary chemotherapy: predictive factors for radical treatment (retrospective study of 72 cases)]. / Cancer du sein traité par chimiothérapie première: facteurs prédictifs du traitement radical (étude rétrospective à propos de 72 cas).

Neoadjuvant chemotherapy has become the first-line treatment for locally advanced breast cancers. On the one hand, it allows for increasing options of breast conservation without an increased risk of recurrence, on the other hand it allows for locoregional control of patients with inoperable cancer. However, some clinical, radiological and histological factors are associated with an increased risk of mastectomy, such as microcalcifications, multifocality, SBR1 and 2 grade, cT3 and cT4 stages and overexpressed HER2. The purpose of this study was to determine the predictive factors for mastectomy after neoadjuvant chemotherapy (NAC), whether mastectomy was justified or not histologically and what were the predictors for unjustified mastectomy. We conducted a retrospective study of 72 patients with breast cancer treated by neoadjuvant chemotherapy in the Departments of Gynecology and Medical Oncology at the Fattouma Bourguiba Hospital in Monastir, Tunisia. The rate of conservative treatment was 18.1%; 63.15% for stage T2 tumors. Mastectomy was not justified by definitive histologic diagnosis in 26.3% of cases. In our study, unjustified mastectomy predictors were negative RH status and CT2 stage. This study led to reflection on our practice and its modifications. Conservative surgery should be considered as standard therapy and should be routinely suggested to all patients treated with neoadjuvant chemotherapy for breast cancer, including the cases with multifocality, large clinical tumor size, extensive microcalcifications, in order to significantly reduce the number of unjustified mastectomies.

[Cytogenic chorion sarcoma: clinical and radiological features]. / Le sarcome du chorion cytogène: aspects cliniques et radiologiques.

Endometrial stromal sarcomas are rare tumors affecting young women. Diagnosis is most often made after surgery. We here report the case of a 22-year-old girl admitted with pelvic pain associated with metrorrhagias. Imaging objectified heterogeneous uterine mass. The diagnosis of atypical fibroid was suspected. Definitive diagnosis was based on histological examination of the surgical specimen.
