Autopsy findings in 154 patients with germ cell tumors of the testis
Abstract:
Autopsy findings are reviewed in 154 patients treated for germ cell tumors of the testis. Of the patients with apparently pure seminoma, 44% had autopsy evidence of nonseminomatous metastases. For all tumor types, the most common sites of distant metastasis were lung (89%), liver (73%), brain (31%), and bone (30%). There was a high incidence of brain metastases in choriocarcinoma and of bone metastases in seminoma. Brain, liver, and bone metastases were late occurrences in the course of the disease and were almost always associated with involvement of other sites. Recurrences in the retroperitoneal area after lymph node dissection occurred mainly in those who had had retroperitoneal lymph node metastases. No difference in site or frequency of metastases was apparent in autopsied patients treated before or after introduction of platinum containing regimens. Respiratory failure, secondary to lung metastases, was the most common cause of death. Of the autopsied patients, 6% died of iatrogenic causes.
Insights
Autopsy reviews reveal that testicular germ cell tumors frequently metastasize to distant sites, including the lungs, liver, and brain. Respiratory failure from lung metastases was the primary cause of death in these patients.
Area of Science:
- Oncology
- Pathology
Background:
- Germ cell tumors (GCTs) of the testis are a significant cause of cancer in young men.
- Understanding metastatic patterns is crucial for improving patient outcomes.
Purpose of the Study:
- To analyze autopsy findings in patients with testicular germ cell tumors.
- To identify common sites and patterns of metastasis and causes of death.
Main Methods:
- Retrospective review of autopsy findings.
- Analysis of 154 patients treated for testicular germ cell tumors.
Main Results:
- 44% of patients with pure seminoma showed nonseminomatous metastases at autopsy.
- Common metastatic sites: lung (89%), liver (73%), brain (31%), bone (30%).
- Brain metastases common in choriocarcinoma; bone metastases in seminoma. Respiratory failure was the leading cause of death.
Conclusions:
- Testicular germ cell tumors exhibit diverse metastatic patterns.
- Metastases to the brain, liver, and bone are typically late-stage events.
- Platinum-based chemotherapy did not alter metastatic patterns in this cohort.
