As the recurrence rate after surgery decreases and treatment outcomes improve, the number of long-term survivors of stomach cancer over 5 years is increasing. In this regard, many patients tend to receive less regular checkups 5 years after surgery or receive endoscopy and abdominal CT irregularly. Accordingly, in many cases, when late recurrence or recurrence due to residual stomach cancer occurs 5 years after surgery, the survival rate is significantly lower.
However, a recent study showed that even patients five years after surgery can significantly increase their survival rate through regular follow-up. In addition, rather than delaying follow-up for more than 2 years or performing endoscopy and abdominal CT irregularly for patients 5 years after surgery, regular check-ups performed in parallel are helpful in improving the survival rate after late-stage recurrence. appeared.
Lee Joo-hee, professor of surgery at Hanyang University Hospital, published a paper titled ‘Feasibility of Extended Postoperative Follow-Up in Patients With Gastric Cancer’ in the June online edition of the SCI-level international academic journal 『JAMA Surgery, citation index 16.9』. It was revealed on the 30th.
This study was conducted on 40,468 patients who underwent gastrectomy by analyzing Korea National Health Insurance (NHI) data. As a result of the study, among patients five years after surgery, the group that received regular follow-up showed a significant difference in overall mortality and survival after recurrence compared to the group that did not.
In particular, the survival rate after recurrence of patients who received regular follow-up in the event of late recurrence or residual gastric cancer was 71.1%, which was much higher than the 32.7% of patients who did not receive follow-up.
According to the study, the 15-year mortality rate after stomach cancer surgery could be reduced from 49.4% to 36.9% through regular follow-up. In addition, approximately 8% of patients experience late recurrence 5 years after gastric cancer surgery, and regular follow-up using endoscopy and abdominopelvic CT before diagnosis of recurrence improves the survival rate after late recurrence to 74.5%. When only a single test was used, the survival rate was lower than this.
Professor Lee said, “Existing guidelines only recommend follow-up for 5 years after gastric cancer surgery, but the results of this study show that regular follow-up is necessary even beyond 5 years.” He added, “In particular, regular examinations combining endoscopy and abdominal CT are required. “It is a great help in detecting recurrence early and increasing the survival rate,” he emphasized.
Follow-up interval was also found to be an important factor. If the interval between endoscopy or abdominopelvic CT examination exceeded 2 years, the survival rate after recurrence decreased significantly.
For endoscopy, the risk of death was 1.72 times higher, and for abdominal CT, it was 1.48 times higher. This highlights why patients need regular follow-up.
Professor Lee said, “This study heralds an important change in the management of stomach cancer patients. Even if it has been more than 5 years since stomach cancer surgery, systematic management is needed to detect recurrence early and increase survival rates through regular follow-up.” “It is necessary,” he said.
