简介：AbstractGastric cancer, which has a high incidence and poor prognosis, remains a therapeutic challenge. Recently, neoadjuvant therapy has attracted increasing attention due to high recurrence rate and low survival rate after resection in most patients with advanced stage. Clinical trials show that neoadjuvant approaches confer a significant survival advantage for resectable locally advanced gastric cancer. The specific advantages of chemoradiotherapy compared with chemotherapy have not been clarified; optimal regimens and cycles, particularly in the preoperative setting, should be studied further; and trials aimed at determining the role of targeted and immunological therapies should be conducted.

简介：AbstractThe management of pancreatic cancer has dramatically changed since the first major randomized trial published in 2001 by the European Study Group for Pancreatic Cancer (ESPAC) stimulated the development of multimodality oncosurgical therapies. ESPAC-1 demonstrated a survival improvement from upfront surgery of only 8%, increasing to 21% 5-year survival for 5-fluorouracil/folinic acid but only 10.8% for chemoradiotherapy. ESPAC-4 has shown a 5-year survival rate of 30% for all patients without restriction of 30% using a combination of gemcitabine and capecitabine, rising to 40% in those with an R0 resection margin, or nearly 50% in those with N0 lymph node status. In selected patients with favorable prognostic features mFOLFIRINOX can produce a 50% 5-year survival rate but with added toxicity. While a positive resection margin is associated with an increased likelihood of local recurrence, this of itself is not the contributor to reduced survival, but rather reflects the increased probability of systemic disease. Thus, strategies aimed at local control, may reduce subsequent local progression, but will not improve overall survival. Neoadjuvant chemotherapy is increasingly utilized in cases of borderline resectable or locally advanced pancreatic cancer, but there is still a lack of proof of concept studies. High-quality evidence from randomized controlled trials to identify the indications and benefits of neoadjuvant therapy in pancreatic cancer are required. The use of patient-derived tumor organoids may predict response to chemotherapy which could open a new opportunity in pancreatic cancer treatment, stratifying patients into treatment groups based on their response to these therapies in the laboratory.

简介：AbstractIncreasing numbers of targeted drugs are used in hormone receptor (HR)-positive metastatic breast cancer (MBC) to overcome or delay resistance to endocrine therapy. This study will systemically review the progress made in endocrine therapy combined with targeted therapy in the treatment of HR-positive MBC. From the "AI (aromatase inhibitor) era" represented by aromatase inhibitors, we have gradually entered the "post-AI era" represented by fulvestrant. Under the guidance of research on the molecular mechanism of endocrine therapy resistance, the "combination of endocrine therapy and targeted therapy" era is approaching. The development of drugs that target endocrine therapy resistance has concentrated on cyclin-dependent kinase 4/6 inhibitors, histone deacetylase inhibitors, and inhibitors of drug targets in the phosphatidylinositol 3 kinase-protein kinase B-mammalian target of rapamycin (PI3K-AKT-mTOR) pathway, providing new strategies for HR-positive MBC. Exploring biomarkers to guide the more precise use of targeted drugs in endocrine therapy for MBC is the focus of current and future research.

简介：AbstractBismuth-containing quadruple therapy (BQT) has long been recommended for Helicobacter pylori (H. pylori) eradication in China. Meanwhile, in the latest national consensus in China, dual therapy (DT) comprising an acid suppressor and amoxicillin has also been recommended. In recent years, the eradication rate of H. pylori has reached >90% using DT, which has been used not only as a first-line treatment but also as a rescue treatment. Compared with BQT, DT has great potential for H. pylori eradication; however, it has some limitations. This review summarizes the development of DT and its application in H. pylori eradication. The H. pylori eradication rates of DT were comparable to or even higher than those of BQT or standard triple therapy, especially in the first-line treatment. The incidence of adverse events associated with DT was lower than that with other therapies. Furthermore, there were no significant differences in the effects of dual and quadruple therapies on gastrointestinal microecology. In the short term, H. pylori eradication causes certain fluctuations in the gastrointestinal microbiota; however, in the long term, the gastrointestinal microbiota eventually returns to its normal state. In the penicillin-naïve population, patients receiving DT have a high eradiation rate, better compliance, lower incidence of adverse reactions, and lower primary and secondary resistance to amoxicillin. These findings suggest the safety, efficacy, and potential of DT for H. pylori eradication.
