The 12-year Experience - A Retrospective and Hospital-based Study of Gestational Trophoblastic Neoplasia in the Northwest of China

Purpose: To analyze clinical features of gestational trophoblastic neoplasia (GTN) patients who received initial treatments at the First Affiliated Hospital of Xi'an Jiaotong University.Methods: The patient record system was screened to extract clinical data including demographics, pregnancy history, diagnosis, staging, prognostic score, treatment. Student t test, x2 test, and Fischer’s exact test were used.Results: This study included 387 patients with GTN. Patients were divided into 2009-2014 and 2015-2020 groups, including 177 and 210 cases, respectively. Patients in 2015-2020 group had higher parity than those in 2009-2014 group (1.2±1.2 vs 0.9±1.2, P=0.030). Nullípara (73 [41.2%] vs 65 [31.0%]) and primípara (71 [40.1%] vs 84 [40.0%]) were more frequently seen in 2009-2014 group than those in 2015-2020 group, but multípara (61 [29.0%] vs 33 [18.7%]) was more common in 2015-2020 group (P=0.028). For patients in 2015-2020 group, more patients demonstrated 1 or more metastases (107 [51.0%] vs 63 [35.6%], P=0.014) than those in 2009-2014 group. Patients in 2015-2020 group had more distant invasions affecting more organs, including lungs (76 [36.2%] vs 52 [29.4%]) and lungs combining with other organs (31 [14.8%] vs 11 [6.2%]), than those in 2009-2014 group (P=0.003).Conclusions: Although patients diagnosed with GTN between 2015 to 2020 is associated with higher parity, more children, and more distant metastases, we cannot simply conclude that clinical features of GTN has changed over time.
