Abstract PDF: Purpose
In 2019, we reported a novel nomogram to predict lymph node metastasis (LNM) in T1 colorectal cancer. Herein, we conducted a survey-based study to evaluate the clinical utility of this nomogram in determining the need for additional surgery after endoscopic resection for high-risk T1 colorectal cancer.
Methods
A survey was conducted among 77 members of the Korean Society of Coloproctology and 25 members of the Korean Society of Gastrointestinal Endoscopy. The survey assessed decision-making regarding additional surgery after endoscopic resection for high-risk T1 colorectal cancer according to various predicted LNM rates (3%, 10%, and 27%) and tumor locations (anal verge [AV] 2, 7, and 25 cm). Additionally, participants provided feedback regarding the reliability, usefulness, and potential adoptability of the prediction model in patient counseling.
Results
Of the 2,314 surveys distributed, 102 responses were analyzed. A trend was observed in which tumors located closer to the anus and associated with a lower predicted risk of LNM were less likely to lead respondents to opt for surgery (e.g., AV 2 cm and 3% of predicted LNM risk, 21.6% opt for surgery vs. AV 25 cm and 27% of predicted LNM risk, 98.0% opt for surgery). Additionally, 94.1% of the respondents reported that the prediction model would be helpful in clinical decision-making and patient counseling.
Conclusion
Our findings suggest that the nomogram is an effective and reliable tool for guiding treatment strategies and enhancing consultations in patients with T1 colorectal cancer.

Purpose
Rectal cancer treatment has a wide range of possible approaches from radical extirpative surgery to nonoperative watchful waiting following chemoradiotherapy, with or without, additional chemotherapy. Our goal was to assess the personal opinion of active practicing surgeons on rectal cancer treatment if he/she was the patient.
Methods
A panel of the International Society of University Colon and Rectal Surgeons (ISUCRS) selected 10 questions that were included in a questionnaire that included other items including demographics. The questionnaire was distributed electronically to ISUCRS fellows and other surgeons included in our database and remained open from April 16 to 28, 2020.
Results
One hundred sixty-three specialists completed the survey. The majority of surgeons (n=65, 39.9%) chose the minimally invasive (laparoscopic) surgery for their personal treatment of rectal cancer. For low-lying rectal cancer T1 and T2, the treatment choice was standard chemoradiation+local excision (n=60, 36.8%) followed by local excision±chemoradiotherapy if needed (n=55, 33.7%). In regards to locally advanced low rectal cancer T3 or greater, the preference of the responders was for laparoscopic surgery (n=65, 39.9%). We found a statistically significant relationship between surgeons’ age and their preference for minimally invasive techniques demonstrating an age-based bias on senior surgeons’ inclination toward open approach.
Conclusion
Our survey reveals an age-based preference by surgeons for minimally invasive surgical techniques as well as organ-preserving techniques for personal treatment of treating rectal cancer. Only 1/4 of specialists do adhere to the international guidelines for treating early rectal cancer.

Purpose
Pertaining to the Colorectal Surgery Society of Australia and New Zealand (CSSANZ) Executive and Research Support Committee, this study aimed to assess the usefulness and outcomes of surveys sent out by the society to its members.
Methods
From 2009 to 2017, CSSANZ members received 38 surveys, most of which were distributed from within the society, and a few of which originated from other affiliated groups. Surveys were categorised by type, topics, times required for completion, delivery method, response rates, and advancement to publication.
Results
Of 38 surveys, 20 (53%) were published and 18 remain unpublished. Four surveys were distributed annually on average, with 2.2 published annually on average, with a mean impact factor of 2.41 ± 1.55. Mean time to publication was 31 ± 17 months. Surveys contributed to 13 publications (34%). The most common survey topics were rectal cancer decisionmaking, in 6 publications (16%), preoperative assessment of colorectal patients, in 5 publications (13%), and anal physiology: continence and defaecation, in 4 publications (11%). Publication of surveys was not related to the number of surveys distributed per year, the number of questions per survey, or the time required by respondents to complete the surveys.
Conclusion
Most of the CSSANZ-distributed surveys resulted in publications, and one third of the surveys contributed to higher degrees obtained by investigators. These surveys aid research into areas that are otherwise difficult to assess, often indicating areas for future research.
