1Stepwise approach and surgery for gallbladder adenomyomatosis: a mini-review显示文摘BACKGROUND: Gallbladder adenomyomatosis (GBA) is a hyperplastic disease affecting the wall of the gallbladder, with some typical features. It has historically been considered a benign condition, nevertheless recent reports highlighted a potential role of GBA in predisposing to malignancies of the gallbladder. DATA SOURCES: We reviewed the literature concerning GBA from its identification until July 2012. Owing to the relative rarity of the disease, studies often are case reports or case series. Thus we herein report a summary of the key-points concerning diagnosis and treatment of GBA, easily applicable in everyday practice, rather than a systematic review. Also, results are integrated with our recent experience. RESULTS: In our experience, we observed a trend toward an increase of GBA during the last years, probably due to enhanced ultrasonographic technical advancements and physician's expertise. GBA has distinctive imaging features. Several recent reports highlight the potential risk of cancer associated with GBA; however the disease is still classified as a benign condition. Although its correlation with malignancy has not been demonstrated, it is prudent to recommend cholecystectomy in some cases. However, in selected asymptomatic patients, a wait-and-see policy is a viable alternative. We propose an algorithm, based on GBA pathological pattern (diffuse, segmental, localized or fundal), suitable for decision-making.CONCLUSIONS: In symptomatic patients and if the diagnosis is doubtful, cholecystectomy is mandatory. Postponing surgery is an option to be offered to asymptomatic patients with low-risk GBA pattern who adhere to scheduled follow-ups.Gianluca Pellino Guido Sciaudone Giuseppe Candilio Giuseppe Perna Antonio Santoriello Silvestro Canonico Francesco SelvaggiAuthor 2013Hepatobiliary & Pancreatic Diseases International2013,12,2:9
2Precision medicine in gastric cancer显示文摘Gastric cancer(GC)is a complex disease linked to a series of environmental factors and unhealthy lifestyle habits,and especially to genetic alterations.GC represents the second leading cause of cancer-related deaths worldwide.Its onset is subtle,and the majority of patients are diagnosed once the cancer is already advanced.In recent years,there have been innovations in the management of advanced GC including the introduction of new classifications based on its molecular characteristics.Thanks to new technologies such as next-generation sequencing and microarray,the Cancer Genome Atlas and Asian Cancer Research Group classifications have also paved the way for precision medicine in GC,making it possible to integrate diagnostic and therapeutic methods.Among the objectives of the subdivision of GC into subtypes is to select patients in whom molecular targeted drugs can achieve the best results;many lines of research have been initiated to this end.After phase III clinical trials,trastuzumab,anti-Erb-B2 receptor tyrosine kinase 2(commonly known as ERBB2)and ramucirumab,anti-vascular endothelial growth factor receptor 2(commonly known as VEGFR2)monoclonal antibodies,were approved and introduced into first-and second-line therapies for patients with advanced/metastatic GC.However,the heterogeneity of this neoplasia makes the practical application of such approaches difficult.Unfortunately,scientific progress has not been matched by progress in clinical practice in terms of significant improvements in prognosis.Survival continues to be low in contrast to the reduction in deaths from many common cancers such as colorectal,lung,breast,and prostate cancers.Although several target molecules have been identified on which targeted drugs can act and novel products have been introduced into experimental therapeutic protocols,the overall approach to treating advanced stage GC has not substantially changed.Currently,surgical resection with adjuvant or neoadjuvant radiotherapy and chemotherapy are the most effective treatments for this disease.Future research should not underestimate the heterogeneity of GC when developing diagnostic and therapeutic strategies aimed toward improving patient survival.Patrizia Bonelli Antonella Borrelli Franca Maria Tuccillo Lucrezia Silvestro Raffaele Palaia Franco Maria Buonaguro 2019World Journal of Gastrointestinal Oncology2019,11,10:8
