Pathological complete response in invasive breast cancer treated by skin sparing mastectomy and immediate reconstruction following neoadjuvant chemotherapy and radiation therapy: Comparison between immunohistochemical subtypes.

CONTEXT: Even if neoadjuvant chemotherapy (NACT) and oncoplastic techniques have increased the breast conserving surgery rate, mastectomy is still a standard for multifocal or extensive breast cancers (BC). In the prospect of increasing breast reconstruction, an alternative therapeutic protocol was developed combining NACT with neoadjuvant radiation therapy (NART), followed by mastectomy with immediate breast reconstruction (IBR). The oncological safety of this therapeutic plan still needs further exploration. We assessed pathological complete response (pCR) as a surrogate endpoint for disease free survival. METHODS: Between 2010 and 2016, 103 patients undergoing mastectomy after NACT and NART were recruited. After CT and RT were administrated, a completion mastectomy with IBR by latissimus dorsi flap was achieved 6 to 8 weeks later. pCR was defined by the absence of residual invasive disease in both nodes and breast. Histologic response was analyzed for each immunohistochemical subset. RESULTS: pCR was obtained for 53.4% of the patients. This pCR rate was higher in hormonal receptor negative (HER2 and triple negative) patients when compared to luminal tumours (69.7% vs 45.7%, p=0.023). DISCUSSION: The pCR rate found in this study is higher than those published in studies analyzing NACT (12.5%-27.1%). This can be explained by the combination of anthracycline and taxane, the use of trastuzumab when HER2 was overexpressed but also by RT associated to NACT. CONCLUSION: Inverting the sequence protocol for BC, requiring both CT and RT, allows more IBR without diminishing pCR and should therefore be considered as an acceptable therapeutic option.

A randomized clinical trial of adjuvant chemotherapy with doxorubicin, ifosfamide, and cisplatin followed by radiotherapy versus radiotherapy alone in patients with localized uterine sarcomas (SARCGYN study). A study of the French Sarcoma Group.

BACKGROUND: There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS. METHODS: Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m² d1, ifosfamide 3 g/m²/day d1-2, cisplatin 75 mg/m² d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment. RESULTS: Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41). CONCLUSION: API adjuvant CT statistically increases the 3 year-DFS of patients with US.

[Unusual twin pregnancy: one in the pseudo-unicornate uterus and the other in the rudimentary uterine horn. Discussion on the diagnosis and management during pregnancy]. / Grossesse gémellaire exceptionnelle: association d'une grossesse dans l'utérus pseudo-unicorne et d'une grossesse dans la corne utérine rudimentaire. Discussion sur le diagnostic et la conduite à tenir pendant la grossesse.

An unusual twin pregnancy was diagnosed echographically at 18 weeks gestation and confirmed by magnetic resonance imaging. One foetus was in a pseudo unicornis uterus and the other in a rudimentary uterus cornu. The risk in such cases, as also reported in the literature, is rupture of the rudimentary cornu at about 20 weeks gestation. In this case the patient was carefully monitored to 23 weeks when the pregnancy in the rudimentary cornu stopped spontaneously. The foetus in the pseudounicornis developed normally to 38 week term. This exceptional observation emphasizes the risk of pregnancy in a blind uterus cornu.

[Infantile polycystic hepatorenal disease. 2 consecutive cases in a patient. Ultrasonic diagnosis and indication for elective pregnancy termination]. / Maladie polykystique hépatorénale infantile. Deux cas consécutifs chez une patiente. Diagnostic échographique et indication d'interruption médicale de grossesse.

We report a case of infantile polycystic kidney disease, during the course of two consecutive pregnancies in the same woman. Observed rates of recurrence in families at risk is higher than theoretical rates (25%). Antenatal ultrasound can show signs of bilateral involvement, which is always lethal and generally leads to elective termination of pregnancy. Diagnosis can rarely be made before 24 weeks of pregnancy.

[Giant breast fibroadenoma]. / Le fibro-adénome mammaire géant.

We report a case of giant fibroadenoma of the breast, "juvenile type", in a 15 year old girl. We study the characteristics of this tumor that occurs in adolescents females, the differential diagnosis with cystosarcoma phylloide and benign virginal hypertrophy, and treatment. Follow-up is recommended because of possible recurrent tumor of a short time.

[Hematocolpometra and local estrogen therapy: an overdose of promestriene?]. / Hématocolpométrie et estrogénothérapie locale: surdosage au Promestriène?

We report a case of hyperestrogenisation which showed itself by the presence of a haematocolpometra in an elderly lady which could be attributed to prolonged and continuous treatment with Promestriene cream. Haematocolpometra is due to intra-uterine haemorrhage (itself due to hyperplastic endometrial polyps) with vaginal stenosis caused by vaginal atrophy that existed before local treatment was started. The Pomestriene is an estrogenic substance which works locally and does not seem to cause much in the way of general effects when used for short courses. If when it is used in large doses over a prolonged period of time, however, it is necessary to look for generalised hyperestrogenisation. Further studies are needed to confirm these finding.
