RESUMO

OBJECTIVE: The objective of this study was to systematically evaluate the data regarding the use of neoadjuvant, perioperative, surgical, and adjuvant treatment options in localized gastric cancer patients and to develop Appropriate Use Criteria recommended by a panel of experts convened by the American Radium Society. METHODS: Preferred reporting items for systematic reviews and meta-analyses methodology was used to develop an extensive analysis of peer-reviewed phase 2/2R/3 trials, as well as meta-analyses found within the Ovid Medline database between 2010 and 2020. The expert panel then rated the appropriateness of various treatments in 5 representative clinical scenarios through a well-established consensus methodology (modified Delphi). RESULTS: For patients with medically operable locally advanced gastric cancer, the strongest recommendation was for perioperative chemotherapy based on high-quality data. Acceptable alternatives included surgery followed by either chemotherapy or concurrent chemoradiotherapy (CRT). For patients with upfront resection of stages I to III gastric cancer (no neoadjuvant therapy), the group strongly recommended adjuvant therapy with either chemotherapy alone or CRT, based on high-quality data. For patients with locally advanced disease who received preoperative chemotherapy without tumor regression, the group strongly recommended postoperative chemotherapy or postoperative CRT. Finally, for medically inoperable gastric cancer patients, there was moderate consensus recommending definitive concurrent CRT. CONCLUSIONS: The addition of chemotherapy and/or radiation, either in the neoadjuvant, adjuvant, or perioperative setting, results in improved survival rates for patients compared with surgery alone. For inoperable patients, definitive CRT is a reasonable treatment option, though largely palliative.

RESUMO

PURPOSE: Limited guidance exists regarding the relative effectiveness of treatment options for nonmetastatic, operable patients with adenocarcinoma of the esophagus or gastroesophageal junction (GEJ). In this systematic review, the American Radium Society (ARS) gastrointestinal expert panel convened to develop Appropriate Use Criteria (AUC) evaluating how neoadjuvant and/or adjuvant treatment regimens compared with each other, surgery alone, or definitive chemoradiation in terms of response to therapy, quality of life, and oncologic outcomes. METHODS AND MATERIALS: Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology was used to develop an extensive analysis of peer-reviewed phase 2R and phase 3 randomized controlled trials as well as meta-analyses found within the Ovid Medline, Cochrane Central, and Embase databases between 2009 to 2019. These studies were used to inform the expert panel, which then rated the appropriateness of various treatments in 4 broadly representative clinical scenarios through a well-established consensus methodology (modified Delphi). RESULTS: For a medically operable nonmetastatic patient with a cT3 and/or cN+ adenocarcinoma of the esophagus or GEJ (Siewert I-II), the panel most strongly recommends neoadjuvant chemoradiation. For a cT2N0M0 patient with high-risk features, the panel recommends neoadjuvant chemoradiation as usually appropriate. For patients found to have pathologically involved nodes (pN+) who did not receive any neoadjuvant therapy, the panel recommends adjuvant chemoradiation as usually appropriate. These guidelines assess the appropriateness of various dose-fractionating schemes and target volumes. CONCLUSIONS: Chemotherapy and/or radiation regimens for esophageal cancer are still evolving with many areas of active investigation. These guidelines are intended for the use of practitioners and patients who desire information about the management of operable esophageal adenocarcinoma.

RESUMO

Prompted by the need to move an aged and sorely neglected print reference collection into a new smaller academic medical library, the Reference Team of the Dana Medical Library at the University of Vermont embarked on a massive project to shrink and revitalize its paper reference collection. Employing a comprehensive and contemporary approach, the project ultimately resulted in a refurbished collection that would more effectively meet the information needs of the 21st century library user. This paper describes the process employed, and the numerous quality improvements to the physical collection, supporting infrastructure, and collection management practices that resulted.
