RESUMEN

BACKGROUND & AIMS: After a first Helicobacter pylori eradication attempt, approximately 20% of patients will remain infected. The aim of the current study was to assess the effectiveness and safety of second-line empiric treatment in Europe. METHODS: This international, multicenter, prospective, non-interventional registry aimed to evaluate the decisions and outcomes of H pylori management by European gastroenterologists. All infected adult cases with a previous eradication treatment attempt were registered with the Spanish Association of Gastroenterology-Research Electronic Data Capture until February 2021. Patients allergic to penicillin and those who received susceptibility-guided therapy were excluded. Data monitoring was performed to ensure data quality. RESULTS: Overall, 5055 patients received empiric second-line treatment. Triple therapy with amoxicillin and levofloxacin was prescribed most commonly (33%). The overall effectiveness was 82% by modified intention-to-treat analysis and 83% in the per-protocol population. After failure of first-line clarithromycin-containing treatment, optimal eradication (>90%) was obtained with moxifloxacin-containing triple therapy or levofloxacin-containing quadruple therapy (with bismuth). In patients receiving triple therapy containing levofloxacin or moxifloxacin, and levofloxacin-bismuth quadruple treatment, cure rates were optimized with 14-day regimens using high doses of proton pump inhibitors. However, 3-in-1 single capsule or levofloxacin-bismuth quadruple therapy produced reliable eradication rates regardless of proton pump inhibitor dose, duration of therapy, or previous first-line treatment. The overall incidence of adverse events was 28%, and most (85%) were mild. Three patients developed serious adverse events (0.3%) requiring hospitalization. CONCLUSIONS: Empiric second-line regimens including 14-day quinolone triple therapies, 14-day levofloxacin-bismuth quadruple therapy, 14-day tetracycline-bismuth classic quadruple therapy, and 10-day bismuth quadruple therapy (as a single capsule) provided optimal effectiveness. However, many other second-line treatments evaluated reported low eradication rates. ClincialTrials.gov number: NCT02328131.

RESUMEN

BACKGROUND: Pancreatic cancer patients are at risk for venous thromboembolism (VTE); the value of thromboprophylaxis has not been definitively established. METHODS: This trial randomized cancer patients initiating a new regimen and at high risk for VTE (Khorana score ≥2) to rivaroxaban 10 mg or placebo up to day 180. This analysis examined the subset of pancreatic cancer patients. The primary efficacy endpoint was the composite of symptomatic deep-vein thrombosis (DVT), asymptomatic proximal DVT, any pulmonary embolism, and VTE-related death. The primary safety endpoint was International Society on Thrombosis and Haemostasis-defined major bleeding. RESULTS: In total, 49/1080 (4.5%) patients enrolled had baseline VTE on screening, with higher rates (24/362 [6.6%]) in pancreatic cancer and they were not randomized. Of 841 randomized patients, 273 (32.5%) had pancreatic cancer; 155/273 (57% in each arm) completed the double-blind period. The primary endpoint occurred in 13/135 (9.6%) patients in the rivaroxaban group and in 18/138 (13.0%) in the placebo group (hazard ratio [HR] = 0.70; 95% CI, 0.34-1.43; P = .328) in up-to-day-180 period and 5/135 (3.7%) patients receiving rivaroxaban and 14/138 (10.1%) receiving placebo in the intervention period (HR = 0.35; 95% CI, 0.13-0.97; P = .034). Major bleeding was similar (2 [1.5%] receiving rivaroxaban and 3 [2.3%] receiving placebo). Correlative biomarker studies demonstrated significant decline in D-dimer (weeks 8 and 16) in patients randomized to rivaroxaban compared to placebo (P < .01). CONCLUSIONS: In ambulatory pancreatic cancer patients, rivaroxaban did not result in significantly lower incidence of VTE or VTE-related death in the 180-day period. During the intervention period, however, rivaroxaban substantially reduced VTE without increasing major bleeding, suggesting benefit of rivaroxaban prophylaxis in this setting.

RESUMEN

In randomized clinical trials, no survival benefit has been observed for selective internal radiation therapy (SIRT) over sorafenib in patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess, through a metaanalysis, whether overall survival (OS) with SIRT, as monotherapy or followed by sorafenib, is noninferior to sorafenib and to compare safety profiles for patients with advanced HCC. Methods: We searched MEDLINE, EMBASE, and the Cochrane Library up to February 2019 to identify randomized clinical trials comparing SIRT, as monotherapy or followed by sorafenib, with sorafenib monotherapy among patients with advanced HCC. The main outcomes were OS and frequency of treatment-related severe adverse events (≥grade 3). The per-protocol population was the primary analysis population. A noninferiority margin of 1.08 in terms of hazard ratio was prespecified for the upper boundary of 95% confidence interval for OS. Prespecified subgroup analyses were performed. Results: Three randomized clinical trials, involving 1,243 patients, comparing sorafenib with SIRT (SIRveNIB and SARAH) or SIRT followed by sorafenib (SORAMIC), were included. After randomization, 411 of 635 (64.7%) patients allocated to SIRT and 522 of 608 (85.8%) allocated to sorafenib completed the studies without major protocol deviations. Median OS with SIRT, whether or not followed by sorafenib, was noninferior to sorafenib (10.2 and 9.2 mo [hazard ratio, 0.91; 95% confidence interval, 0.78-1.05]). Treatment-related severe adverse events were reported in 149 of 515 patients (28.9%) who received SIRT and 249 of 575 (43.3%) who received sorafenib only (P < 0.01). Conclusion: SIRT as initial therapy for advanced HCC is noninferior to sorafenib in terms of OS and offers a better safety profile.

RESUMEN

BACKGROUND: Prospective data on the optimal management of patients with pancreatic ductal adenocarcinoma (PDA) and isolated local manifestation (ILM) after surgery are lacking. Hence, no statements with respect to this entity have been released from most international guidelines including European Society for Medical Oncology, National Comprehensive Cancer Network, and American Society for Clinical Oncology. METHODS: We report for the first time a case-series of 3 patients with PDA and ILM receiving combined systemic chemotherapy and CT-guided high-dose-rate interstitial brachytherapy (CT-HDRBT). RESULTS: CT-HDRBT allowed in all patients with pronounced chemotherapy-induced side effects either a pause of cytostatic treatment or de-escalation to a "maintenance" therapy (dose reduction, interval prolongation, scheme modification with withdrawal of most toxic drugs). CONCLUSION: Combining CT-HDRBT to systemic chemotherapy in patients with PDA and ILM is feasible and safe. As for patients with PDA and ILM no standard of care exists, designing an appropriate randomized prospective trial for this highly selected group of patients is challenging.

RESUMEN

BACKGROUND: Nutritional management of patients with gastric cancer (GC) represents a challenge. SUMMARY: This review provides an overview of the present evidence on nutritional support in patients with GC undergoing surgery as well as in those with advanced disease. KEY MESSAGE: For patients undergoing surgery, the preoperative nutritional condition directly affects postoperative prognosis, overall survival and disease-specific survival. Perioperative nutritional support enriched with immune-stimulating nutrients reduces overall complications and hospital stay but not mortality after major elective gastrointestinal surgery. Early enteral nutrition after surgery improves early and long-term postoperative nutritional status and reduces the length of hospitalization as well. Vitamin B12 and iron deficiency are common metabolic sequelae after gastrectomy and warrant appropriate replacement. In malnourished patients with advanced GC, short-term home complementary parenteral nutrition improves the quality of life, nutritional status and functional status. Total home parenteral nutrition represents the only modality of caloric intake for patients with advanced GC who are unable to take oral or enteral nutrition. PRACTICAL IMPLICATIONS: Early evaluations of nutritional status and nutritional support represent key aspects in the management of GC patients with both operable and advanced disease.
