Prolonged survival after thoracic metastasectomy in patients with nonseminomatous testicular cancer

Abstract Introduction Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates. Methods Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method. Results Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality. Conclusion Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors.

During twenty years of Cisplatin-based therapy the face of nonseminomatous testicular germ cell tumors is still changing: an evaluation of presentation, management, predictive factors and survival

Purpose: To assess the changing presentation and treatment of nonseminomatous testicular germ cell tumors (NSGCT) and to investigate predictive factors for the status of metastasis at diagnosis and on relapse and death. Materials and Methods: Retrospective record review of 147 patients that underwent inguinal orchiectomy from 1987-2007. Follow-up data was available for 102 patients (median follow-up: 80 months (0-243); 96 patients alive). Results: Mean patients age increased (p = 0.015) and more patients were diagnosed in clinical stage I (CSI) (p = 0.040). The fraction of yolk sac (YS) elements inclined (p = 0.030) and pT2 tumors increased (p < 0.001). Retroperitoneal lymph node dissection (RPLND) declined whereas more patients were treated with chemotherapy (p < 0.001; p = 0.004). There was an increase in relapse free (RFS) and cancer specific survival (CSS) due to an improvement in patients with disseminated disease (p = 0.014; p < 0.001). The presence of YS and teratoma elements showed a reduction in the odds ratio (OR) for metastasis at diagnosis (p = 0.002, OR: 0.262; p = 0.009, OR: 0.428) whereas higher pT-stage was associated to their presence (p = 0.039). Patients with disseminated disease (CS > I) showed a declined CSS compared to CSI patients (p = 0.055). The presence of YS elements was associated to an improved RFS (p = 0.038). Conclusions: In our single institution study the face of NSGCT markedly changed over 20 years even after the introduction of Cisplatin-based chemotherapy. These changes were accompanied by an improvement in RFS and CSS. When dealing with NSGCT patients such observations now and in the future should be taken into account. .

A Case of Recurred Primary Mediastinal Nonseminomatous Germ Cell Tumor Associated with Klinefelters Syndrome / 결핵

Primary mediastinal nonseminomatous germ cell tumor associated with Klinefelter's syndrome is a rare disorder. We experienced a case of recurred primary mediastinal nonseminomatous germ cell tumor developed in a 24-year-old patient with Klinefelter's syndrome. The patient had been treated with surgery and combination chemotherapy under the diagnosis of primary mediastinal nonseminomatous germ cell tumor before. A round mass was found on the right lower lung field in the chest X-ray during follow up. The patient was diagnosed as recurred primary nonseminomatous germ cell tumor and Klinefelter's syndrome through tumor markers, peripheral blood karyotyping, and other tests including hormonal assay and was treated with combination chemotherapy and surgery again. When the patient is diagnosed as primary mediastinal nonseminomatous germ cell tumor, Klinefelter's syndrome and hematologic malignancies should be considered to be associated diseases and vice versa.
