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.

Metaplastic breast cancers and triple-negative breast cancers of no special type: are they prognostically different? A systematic review and meta-analysis.

BACKGROUND AND AIMS: Metaplastic breast cancer (MBC) and triple-negative (TN) BC of no special type are often confounded with each other in terms of survival and prognosis. In this systematic study and meta-analysis, we evaluated the prognosis of each of these two different diagnoses. METHODS: We conducted a systematic literature search and review using the MOOSE guidelines, through PUBMED database, the Ovid MEDLINE database, and the ISI Web of Science Citation Index Expanded (SCI Expanded). Overall survival (OS) and disease-free survival (DFS) were the main outcomes considered. RESULTS: Our review eventually selected six independent studies, with a total of more than 59 519 patients. MBC was found to associate with worse OS compared to TNBC of no special type, with a significant 40% increased risk of death [summary hazard ratio (SHR) = 1.40, 95% confidence interval (CI): 1.30-1.50]. We found neither heterogeneity ( I2 = 0%) nor evidence of publication bias ( P = 0.82 and P = 0.49 by Begg's and Egger's test, respectively) between studies. No statistically significant difference was found between MBC and TNBC of no special type in terms of DFS (SHR = 1.17, 95% CI: 0.80-1.71). CONCLUSION: This study demonstrates that TNBC of no special type and MBC have comparable DFS, although the latter presents a significantly worse prognosis in terms of OS. Despite DFS being similar in both subtypes, this did not result in significant OS benefits, with MBC score being the worse of the two diseases.

What About Gastric Schwannoma? A Review Article.

PURPOSE: Gastric schwannomas (GSs) are rare mesenchymal neoplasms of the gastrointestinal tract. Diagnosis is often achieved postoperatively, based on pathology reports of retrieved specimens. The aim of the present study is to follow up all patients with gastric schwannoma (Gs) undergoing endoscopic, partial, or more extended surgery and to evaluate the appearance of local or distant recurrence. METHODS: A PubMed, Cochrane, and Embase systematic review of the literature has been performed. Original papers, review articles, and case reports published between 1988 and 2019 were considered eligible. All the studies who met the inclusion criteria were analyzed. Statistical analysis of data has been performed using GraphPad Prism 7 software. RESULTS: Three hundred twenty-eight articles were found, and a total of 102 were included and analyzed in depth. Fifty-three papers reported the follow-up information, ranging from 1 to 417 months across different studies. Among them, 31 patients underwent endoscopic removal of the gastric lesions; 140 patients underwent local surgery, including wedge resection or partial gastrectomy; and 148 patients underwent subtotal or total gastrectomy. The median follow-up was of 27-38-33 months, respectively. No recurrence or distant metastasis was detected in the endoscopy group. Among local surgery group, liver metastasis was reported in one case; in extended surgery group, one patient died for multiple liver metastases. CONCLUSIONS: Local or more extended surgery involved a larger cohort of patients and reported satisfactory long-term results compared with endoscopy group. Surgery in absence of a definite preoperative diagnosis is considered the gold standard treatment for resectable Gs.

How to do hernioscopy for incarcerated femoral hernia with laparoscopic O-ring retractor system.

Incarcerated groin hernia management often required emergency surgery. Hernioscopy is a safe alternative to repair hernia and explore intra-abdominal cavity. Alexis Laparoscope System is a useful device to perform hernioscopy.

Ileo-ileal intussusception caused by small bowel leiomyosarcoma: A rare case report.

INTRODUCTION: Intussusception is the telescoping of one segment of the bowel into an adjacent bowel segment, causing venous congestion, edema, and blood supply reduction. We present a case of ileo-ileal intussusception in an adult patient with intestinal obstruction caused by a rare mesenchymal malignant lesion of the distal ileum: Leiomyosarcoma (LMS). PRESENTATION OF CASE: A 90-year-old Caucasian man presented to the hospital with a two-day history of abdominal pain, nausea, and bowel occlusion. Preoperative Computer Tomography (CT) showed a solid mass with stratified walls in the lumen of the cecum with the classics "bulls-eye" appearance with concentric rings, suggestive of intussusception. The patient underwent emergency laparotomy with evidence of a small bowel wall tumor driving ileo-ileal intussusception with ischemic damage. Ileocecal resection was performed without postoperative complications. Histopathological examination showed a tumor on the muscular layer of the small bowel. The definitive diagnosis was LMS. DISCUSSION: Adult intussusception is a rare condition, with an incidence of 2/1 000 000 cases per year worldwide. About 60% of patients suffering from this disease require surgery. Clinical presentation can be non-specific because of its no characteristic signs and symptoms. The most common presenting symptom is abdominal pain with bowel obstruction sings. Intussusception can occur anywhere along the small and large intestine and it is typically associated with a Lead Point (LP). The LP may be benign or malignant conditions. Infrequent malignant causes include LMS. CONCLUSION: Diagnosis of intussusception is relatively challenging because of its non-specific symptoms. CT scan is the examimation of choice for the diagnosis because of its peculiar images. In adults, surgical treatment is recommended with laparoscopic or open approach according to surgeon expertise, sometimes in an emergency setting.
