Survival after an antiangiogenetic therapy and surgery in a wide spread growing teratoma originating from a testicular mixed malignant germ cell tumor.
Growing teratoma is still an often unsolved problem especially in male with mixed malignant GCTs of the testis or the mediastinum. This specific situation with progressive tumor growth and simultaneous normalization of tumor markers during or after treatment of malignant GCTs with teratomatous elements is judged as a fatal situation if this situation can not be controlled by extensive surgery, as teratoma are not sensible to chemotherapy or irradiation. Here, we report the case history of a 17-year old male patient with a testicular malignant GCT and wide spread lymph node metastases, who developed a rapidly progressive growing teratoma within the lymph node metastases. Within the molecular profile of the tumor we could find a cytogenetic picture typically found in malignant adult GCTs. In view of the bulky abdominal, thoracic and cervical metastases and the uncontrolled tumor progression, the situation was considered incurable. However, following an individual treatment attempt, this patient was treated with a four-agent combination of drugs with antiangiogenetic potential as well as low-dose cyclic chemotherapy. This approach resulted in a sustained disease stabilization followed by extensive surgical resection of the metastases. We therefore would like to highlight this treatment approach in unresectable growing teratoma and would like to stimulate further research and collaboration to come to an optimized treatment suggestion for this group of poor prognostic patients.
