Long-term outcome of invasive pure micropapillary breast cancer compared with invasive mixed micropapillary and invasive ductal breast cancer: a matched retrospective study.

PURPOSE: Data on the prognostic impact of the micropapillary component in breast cancer are limited. The purpose of this study was to investigate the clinicopathological characteristics and long-term outcomes of pure and mixed invasive micropapillary breast cancer (IMPC) patients compared to invasive ductal cancer (IDC) patients. METHODS: This retrospective study analysed all IMPC and IDC patients treated at the European Institute of Oncology (IEO) between 1997 and 2019. The overall cohort of IMPC patients was divided in two groups, pure and mixed IMPC. Each patient with mixed or pure IMPC was matched with one patient with IDC, based on year of surgery, age, pT, pN, and molecular subtype. RESULTS: A total of 30,115 IDC, 120 pure IMPC and 150 mixed IMPC patients were considered eligible. Compared to IDC, pure and mixed IMPC patients presented a higher rate of locally advanced disease (pT2-T3, pN2-N3), vascular invasion, and Luminal B subtype. After matching, pure and mixed IMPC showed a significant higher rate of vascular invasion compared to IDC patients (p < 0.001). Invasive disease-free survival was better in IDC compared to pure IMPC patients (p = 0.11). Long-term overall survival was significantly worse in pure IMPC group compared to IDC group (p = 0.004), being instead similar between mixed IMPC vs matched IDC (p = 0.07). CONCLUSION: These real-world data reported the worse prognosis of pure IMPC compared to IDC, highlighting the peculiar prognostic value of the micropapillary subtype itself in the decision-making process of IMPC management. An accurate pre-surgical diagnostic evaluation and a multidisciplinary approach are pivotal to best personalize its treatment.

Surgical Management of Inherited Breast Cancer: Role of Breast-Conserving Surgery.

Recent studies have demonstrated that hereditary breast cancer (BC) has a prevalence of 5-10% among all BC diagnoses. Nowadays, significant technological advances in the identification of an increasingly broad spectrum of genetic mutations allow for the discovery of an ever-growing number of inherited pathogenic (P) or likely pathogenic (LP) variants of breast cancer susceptibility genes. As the management of BC patients carrying mutations in the BRCA1/2 genes or other high-penetrance genes is currently a challenge, extensive research is being carried out and a lively scientific debate has been taking place on what the most appropriate local therapy, especially surgical treatment, of patients with inherited BC should be. In many studies, BC outcomes in BRCA carriers and non-carriers have been compared. A number of them showed that, when compared with mastectomy, breast-conserving surgery in BRCA patients is oncologically safe in terms of overall survival, although an increased risk of ipsilateral recurrence was reported. In these patients, devising a specific therapeutic strategy is an inevitably complex process, as it must take into consideration a series of factors, require a multimodal approach, guarantee personalization, strictly adhere to scientific international guidelines, and consider all available evidence. The present narrative review purposes to identify and illustrate evidence from significant selected studies that discussed those issues, as well as to suggest useful tools to clinicians managing this specific clinical condition in daily clinical practice.

Laparoscopic distal gastric and D1 resection for large perforated duodenal bulb peptic ulcer, with intracorporeal antecolic gastrojejunal anastomosis.

BACKGROUND: Peptic ulcer perforation is a common surgical emergency and a major cause of death especially in elderly patients, despite the fact of the presence of effective drug treatments and an increased understanding of its etiology. Giant duodenal perforations, in particular, pose a significant challenge and there is scarce data regarding their optimal management. Laparoscopic surgery is advocated in the surgical treatment of perforated duodenal ulcer disease, in experienced hands. METHODS: Herein we present an 84-year-old man with past medical history of type II diabetes mellitus and hypertension who was admitted to our Department due to epigastric pain and diffuse peritonitis. CT scan revealed the presence of a significant amount of free air and fluid in the upper abdomen secondary to a duodenal perforation. RESULTS: The patient was taken immediately to the theater for an urgent laparoscopy. Methylene blue via the NG tube better defined the extent of the duodenal perforation which was not amenable to a primary repair. Consequently, a decision was made for a laparoscopic pancreas-sparing, ampulla preserving gastroduodenectomy with intracorporeal Billroth II gastrojejunal anastomosis. The postoperative period was uneventful and the patient was discharged on the 13th postoperative day. Histopathology revealed a large benign duodenal ulcer. CONCLUSIONS: Although the incidence of peptic ulcer disease is decreasing, it appears that the incidence of complications is rising. Laparoscopic approach, especially when performed by laparoscopic surgery experts, could be a treatment option for difficult duodenal ulcer perforations with less pain, shorter hospital stay and reduced morbidity.

Higher rate of early-onset preeclampsia in pregnancies following oocyte donation according to increasing maternal age.

OBJECTIVE: To assess the influence of maternal age on the incidence of early-onset preeclampsia requiring delivery before 34 weeks of gestation in pregnancies obtained after oocyte donation. METHODS: We carried out a prospective cohort analysis of 431 single and twin pregnancies, admitted to 3 Tertiary Referral Hospital in Northern Italy between 2008 and 2017. The rate of early-onset PE was calculated and stratified according to maternal age (from 30 to 49 years). A reference population of 11,197 single pregnancies collected prospectively at the first trimester of pregnancy in the same geographic area of Italy and in same hospitals was used to calculate the expected incidence of early-onset PE. RESULTS: In women who delivered after 24 weeks of gestation, the rate of early-onset PE was much higher in oocyte-donation pregnancies, reaching 6.7% (29/431), than the expected rate of 0.5% of the cohort of reference. The mean early PE rate was 4.1% (10/242) in singletons and 10.1% (19/189) in twin pregnancies. According to maternal age, the rate of early PE was 1.16% and 3.12% at 30 years, and 4.98% and 13.14% at 49 years in single and twin pregnancies obtained after oocyte donation, respectively. CONCLUSION: Pregnancies obtained after oocyte donation delivering after 24 weeks had a higher risk of early-onset PE requiring delivery before 34 weeks of gestation, than the general population. The risk is directly correlated with the increase of maternal age and is also higher in twin pregnancies.
