BACKGROUND
Two rat yolk sac tumor cell lines, NMT-1 and NMT-1R, are of the same origin and of different sensitivity to irradiation and to heat. The aim of this study was to investigate the sensitivities of these two cell lines to combined treatments of low-dose irradiation at 2 Gy and hyperthermia
We investigated cell susceptibility to hyperthermia-induced apoptosis in two rat yolk sac tumor cell lines (RYSTs) and attempted to correlate this with the known potentially relevant molecular determinants of apoptosis, p53 protein status, Bcl-2 family of proteins and heat shock proteins (Hsp).
In this study treatment results in children and adolescents (n = 32) suffering from loco-regional abdominal relapses of germ cell tumors (GCT) (7 embryonal carcinoma, 17 Yolk sac tumors, 8 immature teratomas) aged from 1;0 to 23;3 years (mean = 10;11 years) were evaluated. In this pilot study 9
Four children with yolk sac tumor were treated with an aggressive combination chemotherapy program. Three children had presacral primary tumors, one having pulmonary metastases, and one had a testicular primary tumor with pulmonary metastases. Three children were treated when they had measurable
Three patients with endodermal sinus tumor of the mediastinum and two with endodermal sinus tumor mixed with other histologies were treated with CEBA (cisplatin, etoposide, bleomycin, and doxorubicin [Adriamycin]) and by cytoreductive surgery. Three patients treated with CEBA followed by surgery
A 36-year-old male with a history of immature teratoma and embryonal carcinoma of the testis was admitted to the hospital for abdominal pain and fever. A CT scan revealed a large right abdominal mass. The patient's serum alpha-fetoprotein (AFP) was 46.8 ng/ml (reference < 25 ng/ml). Fine-needle
Cardiac metastasis of germ cell tumors is extremely rare, particularly in females. We report a case of a 26-year-old previously healthy woman who presented with a 5-month history of abdominal pain, weight loss, fever, generalized lymphadenopathy, and acanthosis nigricans. Biopsy of cervical lymph
The first known case of primary anterior mediastinal endodermal sinus (yolk sac) tumor in a female patient, occurring in a 20-month-old infant, is reported. The child presented with cough, fever, and listlessness. Chest x-ray revealed a right anterior mediastinal mass. At thoracotomy a large
BACKGROUND
Yolk sac tumor (YST), embryonal carcinoma (EC), choriocarcinoma (CC), and combined germ cell tumors (CGCTs) of the mediastinum are uncommon neoplasms. Only sporadic cases have been documented in the literature; therefore, the clinical behavior of these tumors when located in the
Yolk sac tumor (YST), which most frequently arises in the gonads as a type of germ cell tumor, is rare in children but is highly malignant. It has been suggested that alpha-fetoprotein (AFP) can be applied as a feasible tumor marker because its level was elevated in >90% of YST. The treatment
A 2-year-old male child presented with fever, complete heart block, and congestive cardiac failure. Echocardiography showed a dumbbell-shaped mass in the right ventricle and right atrium. He was operated on with a provisional diagnosis of rhabdomyoma. Histopathology and immunohistochemistry of the
In males, precocious puberty (PP) is defined as the development of secondary sexual characteristics before age 9 years. PP is usually idiopathic; though, organic abnormalities including tumors are more frequently found in male patients with PP. However, advanced puberty in male also can be an
Objective: To explore the clinical outcome of advanced testicular nonseminomatous germ cell cancer patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND), and to analyze the relevant prognostic factors of lymph node pathological. Methods: A total of 43 consecutive
A rare case of CA19-9-producing testicular tumor is reported. A 37-year-old male who had complained of high fever and right scrotal swelling was referred to our department. Ultrasonography and computed tomography demonstrated a right testicular tumor with right lung metastasis and aortocaval lymph
Objective: To understand the clinical manifestation, imaging characteristics and outcomes of pulmonary malignant tumors in children. Method: We retrospectively collected information about seven cases of pulmonary malignant tumors in children in our hospital from Jan 2010 to Dec 2016. The information
