Neoplastic progression risk in females with Barrett's esophagus: a systematic review and meta-analysis of individual patient data.

BACKGROUND AND AIMS: Females with Barrett's esophagus (BE) have a lower risk of neoplastic progression than males, but sufficiently powered risk analyses are lacking. This systematic review and meta-analysis of individual patient data (IPD) aims to provide more robust evidence on neoplastic progression risk in females. METHODS: Systematic literature search of three electronic databases (Medline, Embase, Google Scholar) from inception until August 2023. Eligible studies (1) reported original data on progression from non-dysplastic BE (NDBE), indefinite for dysplasia (IND) or low-grade dysplasia (LGD) to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC), and (2) included female and male patients. IPD were quality controlled by two independent reviewers. Primary outcome was the association between sex and neoplastic progression risk, adjusted for risk factors using multivariable Cox regression analysis. Secondary outcomes were sex differences in time to progression and annual progression rate. RESULTS: IPD were obtained from 11/66 eligible studies, including 2.196 (31%) females. Neoplastic progression risk was lower in females (HR 1.44 for males vs females, 95%CI 1.13-1.82) after adjusting for age, smoking, medication use, hiatal hernia, BE length, and baseline pathology. Annual progression rate was 0.88% in females vs 1.29% in males. Time to progression was similar in both sexes; 3.7 years (IQR 2.1-7.7) in females, and 4.2 years (IQR 2.0-8.1) in males. CONCLUSION: Although females had a lower neoplastic progression risk, sex differences were smaller than previously reported and time to progression was similar for both sexes. Future research should focus on other factors than sex to identify low- and high-risk BE patients.

A comparison of carboplatin and paclitaxel with cisplatinum and 5-fluorouracil in definitive chemoradiation in esophageal cancer patients.

BACKGROUND: In esophageal cancer (EC) patients who are not eligible for surgery, definitive chemoradiation (dCRT) with curative intent using cisplatinum with 5-fluorouracil (5-FU) is the standard chemotherapy regimen. Nowadays carboplatin/paclitaxel is also often used. In this study, we compared survival and toxicity rates between both regimens. PATIENTS AND METHODS: This multicenter study included 102 patients treated in five centers in the Northeast Netherlands from 1996 till 2008. Forty-seven patients received cisplatinum/5-FU (75 mg/m(2) and 1 g/m(2)) and 55 patients carboplatin/paclitaxel (AUC2 and 50 mg/m(2)). RESULTS: Overall survival (OS) was not different between the cisplatinum/5-FU and carboplatin/paclitaxel group {[P = 0.879, hazard ratio (HR) 0.97 [confidence interval (CI) 0.62-1.51]}, with a median survival of 16.1 (CI 11.8-20.5) and 13.8 months (CI 10.8-16.9). Median disease-free survival (DFS) was comparable [P = 0.760, HR 0.93 (CI 0.60-1.45)] between the cisplatinum/5-FU group [11.1 months (CI 6.9-15.3)] and the carboplatin/paclitaxel group [9.7 months (CI 5.1-14.4)]. Groups were comparable except clinical T stage was higher in the carboplatin/paclitaxel group (P = 0.008). High clinical T stage (cT4) was not related to OS and DFS in a univariate analysis (P = 0.250 and P = 0.201). A higher percentage of patients completed the carboplatin/paclitaxel regimen (82% versus 57%, P = 0.010). Hematological and nonhematological toxicity (≥grade 3) in the carboplatin/paclitaxel group (4% and 18%) was significantly lower than in the cisplatinum/5-FU (19% and 38%, P = 0.001). CONCLUSIONS: In this study, we showed comparable outcome, in terms of DFS and OS for carboplatin/paclitaxel compared with cisplatinum/5-FU as dCRT treatment in EC patients. Toxicity rates were lower in the carboplatin/paclitaxel group together with higher treatment compliance. Carboplatin/paclitaxel as an alternative treatment of cisplatinum/5-FU is a good candidate regimen for further evaluation.

What can the Interventional Endoscopist Offer in the Management of Upper Gastrointestinal Malignancies?

The therapeutic possibilities of endoscopy have rapidly increased in the last decades and now allow organ-sparing treatment of early upper gastrointestinal malignancy as well as an increasing number of options for symptom palliation. This review contains an overview of the interventional endoscopic procedures in upper gastrointestinal malignancies. It describes endoscopic treatment of early oesophageal and gastric cancers, and the palliative options in managing dysphagia and gastric outlet obstruction. It also provides an overview of the therapeutic possibilities of biliary endoscopy, such as retrograde stenting and radiofrequency biliary ablation. Endoscopic ultrasound-guided therapeutic options are discussed, including biliary drainage, gastrojejunostomy and coeliac axis block. To aid in clinical decision making, the procedures are described in the context of their indication, efficacy, risks and limitations.
