There is controversy concerning the treatment of stage I yolk sac tumor of the testis, particularly of those with histological factors that indicate a high risk of relapse. Usually orchiectomy alone is sufficient and adjuvant chemotherapy is unnecessary. Retroperitoneal lymphadenectomy is indicated for patients with persistently high alpha-fetoprotein. Once recurred, treatment at that time is thought to be curative. However, postoperative chemotherapy may be necessary for patients with a tumor expressing histological factors that predict possible relapse. In this paper we report on a case of a 2 year old boy whose tumor invaded the testicular veins. The patient suffered from recurrent disease but was successfully treated by chemotherapeutic regimens including cisplatin and retroperitoneal lymphadenectomy. The importance of the histological factors in making a decision on the treatment strategy for stage I testicular yolk sac tumor is discussed. 相似文献

Clinical stage I nonseminomatous germ cell tumors of the testis in childhood and adolescence: an analysis of 31 cases 总被引:2,自引:0,他引:2
Terenziani M Piva L Spreafico F Salvioni R Massimino M Luksch R Cefalo G Casanova M Ferrari A Polastri D Mazza E Bellani FF Nicolai N 《Journal of pediatric hematology/oncology》2002,24(6):454-458
A 20-year single-institution experience of clinical stage I nonseminomatous germ cell tumors of the testis (NSGCTT) in childhood and adolescents was reviewed in relation to clinical characteristics, treatment modalities, and survival. Thirty-one patients with clinical stage I NSGCTT were seen between 1980 and 2000: 14 children and 17 adolescents. Yolk sac tumors and/or teratomas occurred in the children, whereas mixed histologies, including embryonal carcinoma, were predominant in the adolescents. After orchiectomy, the children were assigned to surveillance and the adolescents to active treatment: 16 underwent retroperitoneal lymph node dissection (RPLND) and 1 had adjuvant cisplatin-based chemotherapy because of a high-risk histology. Three of the 14 children (21.4%) relapsed 3, 7, and 8 months after orchiectomy: all 3 had yolk sac tumors and presented with increased alpha-fetoprotein levels. No patients had retroperitoneal relapse; two recurred locally and one in the lung. All three children were treated with cisplatin-based chemotherapy with or without surgery. Among the 16 adolescents undergoing RPLND, 4 (25%) had nodal metastases. Three of the 12 patients (25%) who had negative nodes at RPLND relapsed in the lung 3, 7, and 8 months after RPLND. All were treated with cisplatin-based chemotherapy with or without surgery. Five-year relapse-free and overall survival rates for the whole series were 80.6% and 100%, respectively. This series enabled the authors to pinpoint several important aspects of stage I NSGCTT in children and adolescents. In particular, almost all the childhood cases had the same yolk sac tumor histology, the children tended to have localized disease, and an increased alpha-fetoprotein level had a very high predictive value, suggesting that follow-up should include AFP measurements. A conservative approach is the best option in children, while adolescent NSGCTT behaves like the adult disease and management must include similar treatment strategies. 相似文献

Serum alpha-fetoprotein (AFP) subfraction profile is a predictive indicator for the discrimination of hepatic malignancies, benign liver diseases and yolk sac tumor in adults. In the present study, AFP subfractions were examined in AFP-positive sera from 59 patients of less than 15 years of age. Fractionation of AFP was carried out by lectin affinity crossed-line immunoelectrophoresis. Concanavalin A, Lens culinaris hemagglutinin and phytohemagglutinin E were used as lectins. Fifty-four of 59 (91.5%) AFP subfraction profiles in patients with pediatric diseases were classified into three common types: (1) benign liver disorder, (2) hepatic malignancy and (3) yolk sac tumor. An atypical AFP subfraction profile resembling hepatic malignancy type was found in 5 of 59 (8.5%) infants. It was concluded that estimation of serum AFP subfraction profiles facilitates differential diagnosis of various AFP-positive pediatric diseases, such as hepatoblastoma. hepatoma, hepatic cirrhosis, hepatitis or germ cell tumors. 相似文献

Testicular germ cell tumors occurring during childhood are extremely rare. This study reports the clinical presentation, pathological diagnosis, treatment methods and outcome in a series of 20 boys, aged between 3.5 months and 16 years (median: 1.5 years; 19 were prepubertal), who were treated between 1963 and 2003. Histologically, mature teratoma was present in seven, immature teratoma in four and yolk sac tumor in nine. Nineteen patients were stage I; only one patient was stage IV. Of the 11 teratomas, 10 were treated by orchiectomy and one by testis-sparing tumor excision only. All 11 patients have survived and show no evidence of disease between 10 and 28 years after surgery. The nine patients with yolk sac tumor were managed by orchiectomy, in two plus retroperitoneal lymphadenectomy, and in eight plus chemotherapy. One patient is in remission for 10 months, seven are alive with no evidence of disease for 5.5-23 years, and one patient died from a T-cell acute lymphoblastic leukemia, 2 years after the end of treatment of the testicular tumor. A gradual switch towards less invasive treatment has been observed over the years. This study confirms the excellent cure rates obtained in children with testicular germ cell tumor, provided diagnosis is prompt and treatment accurate. 相似文献

Methods One specimen from testicular yolk sac tumor was cultured in vitro. Testicular yolk sac tumor cell lines were studied morphologically and subjected to karyotype analysis, DNA analysis, and tumor formation evaluation. Results Morphological observation and functional analysis show that cell lines have characteristics of testicular yolk sac tumor. The number of chromosomes varied from 39 to 97. Turours were immunostained positively for AFP in vitro and found to form multiple layers with microvilli. The nuclei were variable and bizarre in size and shape. Conclusions Testicular yolk sac tumor cell lines were cultured proliferated in a stable manner in vitro, which provides a convenient and economical object for basic researches on yolk sac tumor in future. 相似文献

??Objective??To analyze the clinical characteristics and outcomes of children with stage I testicular germ cell tumors??TGCT????and to discuss the treatment strategy for this disease after radical inguinal orchiectomy. Methods??Clinical data of 41 patients with stage I TGCT at Shanghai Children’s Medical Center??Shanghai Jiaotong University School of Medicine between June 2003 to December 2013 were retrospectively analyzed. Their clinical characteristics??therapy and outcomes were analyzed. Results????1??The median age at diagnosis was 18??3 to 43??months old. Among them??38 children??92.7%?? were younger than 3 years old.The pathological subtype included 35 cases of yolk sac??85.4%????4 immature teratoma??9.7%?? and 2 mixed germ cell tumors??4.9%??.??2??Serum AFP levels were elevated in 38 patients??92.7%??. AFP reduced to normal in 27 cases??71.1%??4 weeks after surgery and in 35 cases??92.1%?? after 2 courses of chemotherapy respectively??but 2 cases of them relapsed with AFP increasing again.??3??Forty out of 41 patients underwent surgery and 3??4 courses of chemotherapy with cyclophosvnamide??vincristine and dactinomycin D??VAC??. One patient received surgery alone. The median follow-up period was 64 months. One of the 32 patients who received adjuvant chemotherapy relapsed and then lost follow-up without treatment. The recurrence rate was 3.1% and the 5-year overall survival was 100%. No complication related to chemotherapy occurred during the follow-up. The only one patient treated with surgery alone relapsed at 5 months and achieved complete response after salvage treatment.
