ABSTRACT
Objective To investigate the clinical manifestations and surgical effectiveness of the primary retroperitoneal teratoma in infants.Methods The records of 36 patients were retrospectively reviewed who were diagnosed as primary retroperitoneal teratoma and treated at the Department of Pediatric Oncology,Guangzhou Women and Children's Medical Center between August 2015 and August 2017.The related data were collected,including gender,age,operation time,operational bleeding and tumor weight.All patients took the ultrasound,computed tomography (CT) before surgery,alpha-fetal protein (AFP) and human chorionic gonadotrophin(HCG) were detected during peri-operation period.All cases were classified into 0 to Ⅲ grades according to the Norris classification (27 patients of 0 grade,1 patient of Ⅰ grade,4 patients of Ⅱ grade,4 patients of Ⅲ grade).Results There were 9 males and 27 females in the study.All patients were treated surgically at the age of 11.4 months (7 days-7 years) on the average;the mean weight of incised tumor was 736.47 g (7.90-2 355.00 g);operation time was 2.88 hours (1.08-7.06 hours);the amount of bleeding during operation was 29.11 mL (2-150 mL).All patients received follow-ups for 6.56 months (9 days-23 months) on the average.Radiographs found that tumors in 25 patients (69.4%) were located in the left side of the abdominal cavity,and the rest of them were located in the right side.In addition,tumors in 30 patients (83.3 %) were big enough to pass across the mid-line of the body.Average pre-operation AFP was 7 593.1 μg/L(1.7-80 000.0 μg/L),post-operation AFP was 1 339.5 μg/L(1.4-16 519.6 μg/L),and the difference was statistically significant (P =0.001);pre-operation AFP of the mature group was 5 439.6 μg/L(1.7-80 000.0 μg/L),post-operation AFP of the mature group was 1 130.6 μg/L(1.4-16 519.6 μg/L),and the difference was statistically significant (P =0.001);pre-operation AFP of the immature group [11 182.3 μg/L(17.4-80 000.0 μg/L)] was higher than that of the mature group,and the difference was statistically significant(P =0.006).On the final follow-up,AFP was mean 38.3 μg/L (1.4-352.4 μg/L);among them,AFP of the mature group was mean 14.3 μg/L (1.4-43.3 μg/L),the immature group was 78.4 μg/L(1.7-325.4 μ g/L),and the difference was statistically significant(P =0.028);AFP of 4 patients in the immature group who underwent chemotherapy was 54.9 μg/L (2.6-116.6 μg/L)on the average,lower than those of post-operation AFP of 265.2 μg/L (206.8-384.1 μg/L),and the difference was statistically significant (P =0.042).All patients were treated surgically,and 3 cases of them received laparoscope technique;no significant relationship was proved between time of surgery and the tumor weight,location,and Norris classification(all P > 0.05).The incidence rate of the surgical complications was 42.1%,such as tumor rupture (6 patients),vascular injury (5 patients),digestive tract damage (4 patients) and incomplete incision (1 patient).There was no death case in the serials.Conclusions Primary retroperitoneal teratoma can be completely incised.However,the complications of surgery could appear in many cases.As a predictive index for the recurrence retroperitoneal teratoma,AFP can be diminished by chemotherapy following the surgery.
