Background: Limited data are available on the implementation and effectiveness of NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Gastric Cancer. Purpose: We sought to assess rates of compliance with NCCN Guidelines, specifically stage-specific therapy during the initial episode of care, and to determine its impact on outcomes. Methods: The California Cancer Registry was used to identify cases of gastric cancer from 2001 to 2006. Logistic regression and Cox proportional hazard models were used to predict guideline compliance and the adjusted hazard ratio for mortality. Patients with TNM staging or summary stage (SS) were also analyzed separately. Results: Compliance with NCCN Guidelines occurred in just 45.5% of patients overall. Patients older than 55 years were less likely to receive guideline-compliant care, and compliance was associated with a median survival of 20 versus 7 months for noncompliant care (P<.001). Compliant care was also associated with a 55% decreased hazard of mortality (P<.001). Further analysis revealed that 50% of patients had complete TNM staging versus an SS, and TNM-staged patients were more likely to receive compliant care (odds ratio, 1.59; P<.001). TNM-staged patients receiving compliant care had a median survival of 25.3 months compared with 15.1 months for compliant SS patients. Conclusions: Compliance with NCCN Guidelines and stage-specific therapy at presentation for the treatment of patients with gastric cancer was poor, which was a significant finding given that compliant care was associated with a 55% reduction in the hazard of death. Additionally, patients with TNM-staged cancer were more likely to receive compliant care, perhaps a result of having received more intensive therapy. Combined with the improved survival among compliant TNM-staged patients, these differences have meaningful implications for health services research.

Gastric cancer is the fifth most frequently diagnosed cancer and the third leading cause of death from cancer in the world. Several advances have been made in the staging procedures, imaging techniques, and treatment approaches. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Gastric Cancer provide an evidence- and consensus-based treatment approach for the management of patients with gastric cancer. This manuscript discusses the recommendations outlined in the NCCN Guidelines for staging, assessment of HER2 overexpression, systemic therapy for locally advanced or metastatic disease, and best supportive care for the prevention and management of symptoms due to advanced disease.

Esophageal cancer is the sixth most common cause of cancer deaths worldwide. Adenocarcinoma is more common in North America and Western European countries, originating mostly in the lower third of the esophagus, which often involves the esophagogastric junction (EGJ). Recent randomized trials have shown that the addition of preoperative chemoradiation or perioperative chemotherapy to surgery significantly improves survival in patients with resectable cancer. Targeted therapies with trastuzumab and ramucirumab have produced encouraging results in the treatment of advanced or metastatic EGJ adenocarcinomas. Multidisciplinary team management is essential for patients with esophageal and EGJ cancers. This portion of the NCCN Guidelines for Esophageal and EGJ Cancers discusses management of locally advanced adenocarcinoma of the esophagus and EGJ.

Abstract

Esophageal cancer is the sixth leading cause of cancer-related deaths worldwide. Squamous cell carcinoma is the most common histology in Eastern Europe and Asia, and adenocarcinoma is most common in North America and Western Europe. Surgery is a major component of treatment of locally advanced resectable esophageal and esophagogastric junction (EGJ) cancer, and randomized trials have shown that the addition of preoperative chemoradiation or perioperative chemotherapy to surgery significantly improves survival. Targeted therapies including trastuzumab, ramucirumab, and pembrolizumab have produced encouraging results in the treatment of patients with advanced or metastatic disease. Multidisciplinary team management is essential for all patients with esophageal and EGJ cancers. This selection from the NCCN Guidelines for Esophageal and Esophagogastric Junction Cancers focuses on recommendations for the management of locally advanced and metastatic adenocarcinoma of the esophagus and EGJ.
