Clinical characteristics and long-term management of prepubertal testicular teratomas: a retrospective, multicenter study

Abstract Prepubertal testicular teratomas are rare tumors with limited practical guidance for their management. This study aimed to analyze a large multicenter database to establish the optimal management of testicular teratomas. We retrospectively collected data on testicular teratomas in children younger than 12 years who underwent surgery without postoperative chemotherapy in three large professional children’s institutions in China between 2007 and 2021. The biological behavior and long-term outcomes of testicular teratomas were analyzed. In total, 487 children (with 393 mature teratomas and 94 immature teratomas) were included. Among mature teratomas, 375 cases were testis-sparing, 18 were orchiectomies, 346 were operated through the scrotal approach, and 47 underwent the inguinal approach. The median follow-up period was 70 months, and no recurrence or testicular atrophy was observed. Among the children with immature teratomas, 54 underwent testis-sparing surgery, 40 underwent orchiectomy, 43 were operated through the scrotal approach, and 51 were operated through the inguinal approach. Two cases of immature teratomas with cryptorchidism had local recurrence or metastasis within 1 year of the operation. The median follow-up duration was 76 months. No other patients had recurrence, metastasis, or testicular atrophy. Conclusion: Testicular-sparing surgery is the first treatment choice for prepubertal testicular teratomas, with the scrotal approach being a safe and well-tolerated strategy for these diseases. Additionally, patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. Therefore, these patients should be closely followed up in the first year after surgery. What is Known:• There is a fundamental difference between testicular tumours in childhood and those in adulthood - not only in terms of the difference and incidence but also in terms of histology.• For surgical techniques, the inguinal approach is recommended for the treatment of testicular teratomas in children.What is New:• The scrotal approach being a safe and well-tolerated strategy for testicular teratomas in children.• Patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. These patients should be closely followed up in the first year after surgery. Ausführliche Beschreibung

This study aimed to analyze a large multicenter database to establish the optimal management of testicular teratomas. We retrospectively collected data on testicular teratomas in children younger than 12 years who underwent surgery without postoperative chemotherapy in three large professional children’s institutions in China between 2007 and 2021. The biological behavior and long-term outcomes of testicular teratomas were analyzed. In total, 487 children (with 393 mature teratomas and 94 immature teratomas) were included. Among mature teratomas, 375 cases were testis-sparing, 18 were orchiectomies, 346 were operated through the scrotal approach, and 47 underwent the inguinal approach. The median follow-up period was 70 months, and no recurrence or testicular atrophy was observed. Among the children with immature teratomas, 54 underwent testis-sparing surgery, 40 underwent orchiectomy, 43 were operated through the scrotal approach, and 51 were operated through the inguinal approach. Two cases of immature teratomas with cryptorchidism had local recurrence or metastasis within 1 year of the operation. The median follow-up duration was 76 months. No other patients had recurrence, metastasis, or testicular atrophy. Conclusion: Testicular-sparing surgery is the first treatment choice for prepubertal testicular teratomas, with the scrotal approach being a safe and well-tolerated strategy for these diseases. Additionally, patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. Therefore, these patients should be closely followed up in the first year after surgery. What is Known:• There is a fundamental difference between testicular tumours in childhood and those in adulthood - not only in terms of the difference and incidence but also in terms of histology.• For surgical techniques, the inguinal approach is recommended for the treatment of testicular teratomas in children.What is New:• The scrotal approach being a safe and well-tolerated strategy for testicular teratomas in children.• Patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery.

This study aimed to analyze a large multicenter database to establish the optimal management of testicular teratomas. We retrospectively collected data on testicular teratomas in children younger than 12 years who underwent surgery without postoperative chemotherapy in three large professional children’s institutions in China between 2007 and 2021. The biological behavior and long-term outcomes of testicular teratomas were analyzed. In total, 487 children (with 393 mature teratomas and 94 immature teratomas) were included. Among mature teratomas, 375 cases were testis-sparing, 18 were orchiectomies, 346 were operated through the scrotal approach, and 47 underwent the inguinal approach. The median follow-up period was 70 months, and no recurrence or testicular atrophy was observed. Among the children with immature teratomas, 54 underwent testis-sparing surgery, 40 underwent orchiectomy, 43 were operated through the scrotal approach, and 51 were operated through the inguinal approach. Two cases of immature teratomas with cryptorchidism had local recurrence or metastasis within 1 year of the operation. The median follow-up duration was 76 months. No other patients had recurrence, metastasis, or testicular atrophy. Conclusion: Testicular-sparing surgery is the first treatment choice for prepubertal testicular teratomas, with the scrotal approach being a safe and well-tolerated strategy for these diseases. Additionally, patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. Therefore, these patients should be closely followed up in the first year after surgery. What is Known:• There is a fundamental difference between testicular tumours in childhood and those in adulthood - not only in terms of the difference and incidence but also in terms of histology.• For surgical techniques, the inguinal approach is recommended for the treatment of testicular teratomas in children.What is New:• The scrotal approach being a safe and well-tolerated strategy for testicular teratomas in children.• Patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. These patients should be closely followed up in the first year after surgery.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Testis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Teratoma</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Testis-sparing surgery</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Treatment</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sun, Fenglan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yu, Xin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Ruifeng</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Xiaodong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ouyang, Yaoling</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Zhilin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Shoulin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European journal of pediatrics</subfield><subfield code="d">Berlin : Springer Science & Business Media B.V., 1975</subfield><subfield code="g">182(2023), 4 vom: 16.

abstract	Abstract Prepubertal testicular teratomas are rare tumors with limited practical guidance for their management. This study aimed to analyze a large multicenter database to establish the optimal management of testicular teratomas. We retrospectively collected data on testicular teratomas in children younger than 12 years who underwent surgery without postoperative chemotherapy in three large professional children’s institutions in China between 2007 and 2021. The biological behavior and long-term outcomes of testicular teratomas were analyzed. In total, 487 children (with 393 mature teratomas and 94 immature teratomas) were included. Among mature teratomas, 375 cases were testis-sparing, 18 were orchiectomies, 346 were operated through the scrotal approach, and 47 underwent the inguinal approach. The median follow-up period was 70 months, and no recurrence or testicular atrophy was observed. Among the children with immature teratomas, 54 underwent testis-sparing surgery, 40 underwent orchiectomy, 43 were operated through the scrotal approach, and 51 were operated through the inguinal approach. Two cases of immature teratomas with cryptorchidism had local recurrence or metastasis within 1 year of the operation. The median follow-up duration was 76 months. No other patients had recurrence, metastasis, or testicular atrophy. Conclusion: Testicular-sparing surgery is the first treatment choice for prepubertal testicular teratomas, with the scrotal approach being a safe and well-tolerated strategy for these diseases. Additionally, patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. Therefore, these patients should be closely followed up in the first year after surgery. What is Known:• There is a fundamental difference between testicular tumours in childhood and those in adulthood - not only in terms of the difference and incidence but also in terms of histology.• For surgical techniques, the inguinal approach is recommended for the treatment of testicular teratomas in children.What is New:• The scrotal approach being a safe and well-tolerated strategy for testicular teratomas in children.• Patients with immature teratomas and cryptorchidism may have tumor recurrence or metastasis after surgery. These patients should be closely followed up in the first year after surgery. © The Author(s) 2023
