Abstract
Background: Colorectal cancer (CRC) is a significant health burden, with lymph node dissection (LND) playing a critical role in staging and guiding treatment. However, the optimal extent of LND for the oldest-old population (aged ≥ 90 years) remains undefined because of insufficient targeted clinical data. This study aimed to compare the short-term outcomes of D3 versus non-D3 LND in Stage II-III CRC in oldest-old patients.
Methods: This retrospective cohort study utilized data from the Setouchi Colorectal Neoplasm Registration database, including 282 oldest-old patients with CRC treated between 2011 and 2022. Patients were stratified into D3 and non-D3 LND groups, with inverse-probability-weighted regression adjustment implemented to address potential confounding factors. Postoperative complications and hospital stays were analyzed using regression models and descriptive statistics.
Results: D3 LND resulted in significantly higher lymph node harvests in both Stage II and Stage III patients (p < 0.01). There were no significant differences in overall or major postoperative complications between D3 and non-D3 groups. Hospital stays were comparable for Stage II patients but shorter for Stage III patients in the D3 group (p < 0.01). Complication rates ranged from 28% to 47.7%, with surgical site infections and pneumonia being the most common.
Conclusions: D3 LND can be safely performed in oldest-old patients with CRC without increasing postoperative complications or extending hospital stays. These findings support the feasibility of extensive LND in this age group, but further studies are needed to evaluate its oncological benefits.
期刊介绍：
Techniques in Coloproctology is an international journal fully devoted to diagnostic and operative procedures carried out in the management of colorectal diseases. Imaging, clinical physiology, laparoscopy, open abdominal surgery and proctoperineology are the main topics covered by the journal. Reviews, original articles, technical notes and short communications with many detailed illustrations render this publication indispensable for coloproctologists and related specialists. Both surgeons and gastroenterologists are represented on the distinguished Editorial Board, together with pathologists, radiologists and basic scientists from all over the world. The journal is strongly recommended to those who wish to be updated on recent developments in the field, and improve the standards of their work.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1965 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the Principles of Laboratory Animal Care (NIH publication no. 86-23 revised 1985) were followed as were applicable national laws (e.g. the current version of the German Law on the Protection of Animals). The Editor-in-Chief reserves the right to reject manuscripts that do not comply with the above-mentioned requirements. Authors will be held responsible for false statements or for failure to fulfill such requirements.
