Management of Residual Mass in Germ Cell Tumors After Chemotherapy.

Curr Oncol Rep 2019 Jan 21;21(1). Epub 2019 Jan 21.

Department of Urology, Indiana University School of Medicine, 535 Barnhill Dr., Indianapolis, IN, 46202, USA.

Purpose Of Review: The purpose of this review is to educate medical oncologists on the management of patients with residual germ cell tumors and the role of surgical resection after platinum-based chemotherapy.

Recent Findings: Patients with non-seminomatous testicular cancer and residual enlarged retroperitoneal lymph nodes > 1 cm following induction chemotherapy with normal tumor markers should undergo a post-chemotherapy retroperitoneal lymph node dissection. All patients with primary mediastinal non-seminoma should undergo surgical resection of the mediastinal mass post-chemotherapy. Read More

[A CASE WITH LATE RECURRENCE OF EXTRAGONADAL GERM CELL TUMOR].

Nihon Hinyokika Gakkai Zasshi 2018 ;109(1):40-44

Department of Urology, Nagoya University Graduate School of Medicine.

A 61-year-old man had undergone resection of teratoma with a histological component of seminoma occurring in the anterior mediastinum at 26 years of age in 1978, followed by radiation treatment to the resected area. He had a recurrence tumor in the left retroperitoneum 2 years later, which was resected combined with left nephrectomy and was proved to be the same pathology as the initial tumor. At 36 years after the initial treatment, the tumor recurred in the right lung. Read More

Thoracoscopic resection of a cystic seminoma of the mediastinum.

Asian J Endosc Surg 2018 Sep 5. Epub 2018 Sep 5.

Department of Pathology, Suwa Red Cross Hospital, Suwa, Japan.

Mediastinal seminoma is an uncommon tumor that accounts for 25% of primary mediastinal germ cell tumors, which in turn comprise fewer than 5% of all germ cell tumors. Although CT normally shows a solid, lobulated tumor, mediastinal cystic seminoma has rarely been described. Here, we report a 24-year-old man who presented with a mediastinal cystic tumor that was resected after an 18-month delay via video-assisted thoracoscopic surgery while in the supine position; the procedure involved lifting the chest wall with a subcutaneous Kirschner wire.

Expression and mutation of -Kit in intracranial germ cell tumors: A single-centre retrospective study of 30 cases in China.

Oncol Lett 2016 May 23;11(5):2971-2976. Epub 2016 Mar 23.

Department of Pathology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai 200127, P.R. China.

Although primary central nervous system (CNS) germ cell tumors (GCTs) are one of the most treatable types of malignant brain tumor, a subset of patients remain resistant to standard chemotherapy. Gain-of-function mutations of the -Kit gene, and KIT protein expression, have been observed in a number of GCTs, including testicular seminoma, ovarian dysgerminoma and mediastinal seminoma in various ethnic groups. Although a small number of studies have reported the role of -Kit in CNS GCTs, few have focused on Chinese patients exhibiting CNS GCTs. Read More

Seminoma Presenting as a Mediastinal Mass in an Elderly Patient.

Conn Med 2015 Oct;79(9):527-30

Primary mediastinal germ cell tumors are relatively rare and represent 10% - 20% of all mediastinal tumors. About one-third of these are primary mediastinal seminomas, occurring in males in their third and fourth decades, with the median age of presentation ranging between 20 and 30 years of age. We report an unusual case of a 69-year old male with mediastinal seminoma, who presented at an age much higher than the usual affected patient and responded well to the conventional mode of therapy for this tumor.
