Purpose: To analyze the recurrent rate, time of recurrence, type of recurrence and the relationship between recurrence and histopathologic findings after radical gastrectomy for early gastric cancer and evaluate the usefulness of follow up abdominal computed tomography after surgery.
Materials and Methods: We retrospectively evaluated 617 abdominal computed tomographic examinations of 144 patients (101 male, 43 female, mean age, 53 years) who underwent radical subtotal gastrectomy for early gastric cancer between July 1994 and July 1997. Follow-up abdominal CT scans were reviewed by three abdominal radiologists for detection of recurrence of early gastric cancer, and endoscopic and pathologic findings were correlated. We also reviewed the surgical pathologic reports for location, size, cell type and depth of invasion of early gastric cancer and lymph node invasion. We analyzed the recurrent rate, time and type of recurrence, and relationship between recurrence rate and pathologic characteristics of early gastric cancer.
Results: The recurrent rate was 4.2% (6/144) during 5-7 years after radical subtotal gastrectomy for early gastric cancer. The recurrence was detected on 2-5 years after operation. The types of recurrence were lymph node metastasis (n=5),liver metastasis (n=4), recurrence in the residual stomach or anastomotic site (n=3), adrenal metastasis (n=1), and lung metastasis (n=1). Relationship between recurrence and location, size, depth of invasion and cell type of early gastric cancer and lymph node metastasis was not significant statistically (p>0.4).
Conclusion: The recurrence rate of early gastric cancer after radical subtotal gastrectomy is very low and occurs after two years. The follow up-CT scans can detect all recurrence of early gastric cancer, so regular follow-up abdominal CTexamination is useful.
