2. Recurrent pattern
The median time from the initial diagnoses to first recurrence was 16.3 months (range: 1.0-161.9 months). 33.8% (24/71) patients experienced recurrence after initial diagnoses within 12 months. And other 66.2% (47/71) patients had first recurrence after 12 months (Table 1).
The most common location of first recurrence was the abdominal/pelvic peritoneum, diagnosed in 47 (66.2%) patients, followed by lung metastases in 24 (33.8%) patients, abdominal wall metastases in 13 (18.3%), bone metastases in 5 (7.0%) patient, vaginal cuff metastases in 6 (8.5%) patients (Table 2).
In the entire cohort, multiple metastases in different locations were found in 18 (25.4%) patients. And 31 (43.7%) patients only had abdominal/pelvic peritoneum recurrence, 16 (22.5%) patients only had lung metastases, 3 (4.2%) patients only had abdominal wall metastases, 2 (2.8%) patients only had vaginal cuff metastases, 1 (1.4%) patient only had bone metastasis (Table 3).
