American College of Surgeons Commission on Cancer Standard 5.7 for Total Mesorectal Excision for Mid-to-Low Rectal Cancer

Bibliometric analysis and visualization of research trends in total mesorectal excision in the past twenty years

BACKGROUND

Rectal cancer leads a major disease burden worldwide. Total mesorectal excision (TME) is the standard treatment for locally advanced or node-positive rectal cancer, while attempts to improve the surgery such as laparoscopic and transanal TME are widely used but have their inherent limitations. This bibliometric study analyzed research trends, cooperation, and knowledge dissemination on TME over the past 20 years to inform future directions.

METHODS

Relevant literature from 2003 to 2023 was extracted from the Web of Science Core Collection and analyzed with VOSviewer, CiteSpace, and R for publication patterns, countries, institutions, authors, and research hotspots.

RESULTS

Five thousand three hundred forty-five related publications were included, with rising annual output and citations. The US and China contributed the most studies, while the Netherlands had greater influence. Leiden University ranked first in publications. The top authors were Heald, Kapiteijn, Sauer, Nagtegaal, and Peeters. Research shifted from cancer-focused to patient-centered care and from radiotherapy/chemotherapy to advanced surgery. Multicenter trials became more common.

CONCLUSION

Although the United States and China have the largest number of publications, it should be noted that the influence of these two countries in the field of TME research is not the highest, which does not match the number of publications. In addition, telemedicine, interdisciplinary, medical-industrial integration, etc. may be potential directions for future research in the field of TME.

Meeting the New Commission on Cancer Operative Standards: Where Do We Stand Now?

INTRODUCTION

The 2020 Commission on Cancer accreditation standards 5.7 and 5.8 address total mesorectal excision for rectal cancer and lymph node sampling for lung cancer. The purpose of this review was to assess our institution's compliance with these operative standards, which will be required in 2022 and 2023, and provide recommendations to other military training facilities seeking to comply with these standards.

MATERIALS AND METHODS

A 2018-2020 single institution chart review was performed of operative and pathology reports. Identified deficits were addressed in meetings with colorectal and thoracic surgery leadership, and cases were followed to reassess compliance.

RESULTS

A total of 12 rectal and 48 lung cancer cases met the inclusion criteria and were examined. Pre-intervention compliance for standards 5.7 and 5.8 was 58% and 35%, respectively, because of inadequate synoptic reporting and lymph node sampling. After intervention, compliance was 100%.

CONCLUSIONS

Our institution requires changes to comply with new standards, including in areas of documentation and systematic pulmonary lymph node sampling. We provide lessons learned from our own institutional experience, including practical tips and recommendations to achieve compliance. All military training facilities performing lung and rectal oncologic resections should conduct an internal review of applicable cases in preparation for upcoming American College of Surgeons Commission on Cancer site visits.
