Figure 3. Postoperative survival rates. A. Cancer-specific postoperative survival rates in patients with positive lymph nodes. Patients in the postoperative adjuvant group tended to exhibit more favorable prognoses compared to the surgery-alone group (five-year survival rates: adjuvant group, 59.0%; surgery-alone group, 43.1%). B. Overall postoperative survival (OS) rates in patients with positive lymph nodes. Patients in the postoperative adjuvant group had significantly more favorable prognoses compared to those in the surgery-alone group (five-year survival rates: adjuvant group, 42.0%; surgery-alone group, 20.4%).
