Objective : Cancer is one of the leading causes of death in children. There is the need to have the histologic review of malignancies
in children from the Indian sub–continent.Methods : In the present study, malignant tumors received over 12 years were reviewed and re–classified according to classifications
based on prognosis.Results : A total of 472 tumors were received over 12 years. Of these 318 were benign and 154 malignant. The commonest malignant
solid tumor was lymphoma followed by pediatric renal tumors. The sarcomas included bone tumors, Rhabdomyosarcoma and synovial
sarcoma. There were 13 germ cell tumors, 10 retinoblastomas and six neuroblastomas.Conclusion: The review revealed that a definite diagnosis or classification was not assigned in 21 cases in the original reporting.
Of these 14 could be assigned a definite category on review and immuno-staining. These included five non-Wilms sarcomas, four
Rhabdomyosarcomas, three Ewing’s sarcoma/ PNETs and two Synovial sarcomas. The study also revealed an unexpected high percentage
(11%) of epithelial malignancies in children 相似文献

A dose-intensive regimen of cyclophosphamide (140 mg/kg over 2 days), doxorubicin (Adriamycin, 75 mg/m2 over 3 days), and vincristine (1 mg/m2 on days 1,2, and 3 and 1.5 mg/m2 on day 9) was tested in 18 children and adolescents with poor-prognosis recurrent or refractory solid tumors. Nine were affected by neuroblastoma, 3 by Ewing's tumors, 2 by rhabdomyosarcoma, 2 by synovial sarcoma, 1 by hepatocellular carcinoma, and 1 by osteogenic sarcoma. All enrolled patients were heavily pretreated, including 2 patients after bone marrow transplantation. Forty courses were applied (median, 2). The overall response rate was 33% (2 complete remissions and 4 partial remissions). Responses were obtained in children with neuroblastoma, Ewing's tumors, and hepatocellular carcinoma. Myelosuppression [World Health Organization (WHO) grade IV after all courses] and cardiac toxicity (3 WHO grade I,5 WHO grade III, and 3 WHO grade IV) were the main side effects. Nephrotoxicity and hepatoxicity were not obserued. With further therapy consisting of surgery, radiotherapy, and high-dose chemotherapy [cisplatin, carboplatin/etoposide (VP16), or ifosfaamide/VP16 with or without autologous stem cell reinfusion after conditioning with melphalan/VP16/carboplatin], 3 complete remissions and 5 very good partial remissions were obtained. Ten of 18 Patients are alive after a median follow-up of 16 months. 相似文献

HIV is generally regarded as an acceptable reason to exclude a potential recipient from consideration for transplantation. Most of the data in the literature regarding transplantation of HIV sero-positive individuals pertains to the time prior to the administration of Highly Active Anti-Retroviral Therapy (pre-HAART). This data, therefore, provides little guidance for the management of HIV-positive individuals in the current era. The development of HAART has resulted in a decreased mortality. With prolonged survival more HIV-infected individual are developing end stage organ disease from co-existing conditions such as HCV and HBV, and diseases common in the general population such as diabetes mellitus and hypertension. This has lead to clinicians, researchers and patients to actively investigate the role of solid organ transplantation in HIV-infected individuals. In this article We review the literature to date in liver and renal transplantation, including more recent data in patients receiving HAART. 相似文献

From 1972 to 2000, 123 patients with solid tumors whose complaints had started in the first 28 days of life were retrospectively evaluated. Fifty-five patients were diagnosed in the first 28 days and 68 patients were diagnosed after 28 days. In the former group, 85.5% of patients had symptoms in the first day of life. In the latter group, 77.9% had the onset of symptoms in the first day. Tumor subgroups in the neonatal period included teratoma (34), neuroblastoma (11), rhabdomyosarcoma (3), Wilms tumor (1), and retinoblastoma (3), and the others (3). Three patients had other, less common tumors. In the second group the numbers were the following: for teratoma (32), neuroblastoma (15), germ cell tumors other than teratomas (8), rhabdomyosarcomas (4), the other soft tissue sarcomas (3), Wilms tumor (1), retinoblastoma (1), and other, rare tumors (4). There were 22 malignant tumors in the first group, and 44 in the second group. Fourteen patients in the first group died in the early postoperative period or with progressive disease. Nineteen of 44 patients died in the second group. Overall survival rates were 24.9% and 51.6% in first and second groups, respectively (p = 0.015). Event-free survival rates were 14.7% and 47.7% in these groups, respectively (p = 0.0063). This is the first report comparing clinical features and prognosis of tumors diagnosed in the first 28 days of the life with those diagnosed after 28 days. The prognosis was worse in infants diagnosed in the first 28 days of life. 相似文献

Solid tumors preceding or following sarcoidosis 总被引:4,自引:0,他引:4
H Brincker 《Medical and pediatric oncology》1987,15(2):82-88
Eight cases of sarcoidosis diagnosed after a preceding malignant solid tumor are presented. An analysis of these eight cases along with four previously reported cases was unable to answer the question whether in some cases the development of sarcoidosis may be triggered or modified by a preceding treatment of a malignant tumor. However, in the reverse situation--sarcoidosis preceding cancer--an analysis of 23 such cases from the literature suggests that sarcoidosis preceding cancer appears to be of the chronic active variety and that lung and breast cancer may occur more often than expected after sarcoidosis. Thus, it is conceivable that the immunologic abnormalities associated with sarcoidosis may somehow promote the development of certain malignant tumors. True sarcoidosis may be confused with local sarcoid reactions in cancer patients. One such case is reported in which the finding of a regional sarcoid reaction to a solitary lung metastasis from a uterine adenocarcinoma led to insufficient treatment in the belief that the patient had systemic sarcoidosis. 相似文献

目的 通过对小儿常见的神经母细胞瘤、肾母细胞瘤、横纹肌肉瘤和恶性畸胎瘤的药敏检测,讨论各种常用化疗方案的治疗价值。方法 用17例肿瘤标本,其中神经母细胞瘤5例,化疗方案CCSG。肾母细胞瘤4例,化疗方案为DD方案。横纹肌肉瘤5例,CYVADIC:方案。恶性畸胎瘤3例,PVB方案。用流式细胞术荧光标记法,测定化疗药物敏感性。分析化疗疗效与耐药性。 结果 神经母细胞瘤对烷化剂类(CTX,IFO)、抗代谢药物(ACD)、VM26、TAL敏感性较高(P<0.05),化疗方案与药敏符合率约50%。肾母细胞瘤敏感的药物较多,化疗方案与药敏结果符合率约66.7%。以上两者疗效较好。横纹肌肉瘤耐药性较强。恶性畸胎瘤药敏对化疗方案符合率仪33_3%。两者疗效较差。结论 小儿实体恶性肿瘤现行化疗方案与肿瘤实际的药敏结果有一定的差距。用流式细胞仪测定肿瘤药物敏感性对预测化疗疗效及个体化化疗有指导意义 相似文献

ABSTRACT. We examined 90 survivors of childhood solid tumours diagnosed in our hospital between 1960 and 1976. Their ages at the time of this study ranged from 12.2 to 41.5 years. Adult standing height was usually normal. However, final standing height was less than expected in the females, and sitting height was below the normal mean in the males. The males who had received both chemotherapy and radiation therapy to the spine had a greater decrement in sitting height, but we did not find any association between radiation therapy to the spine without chemotherapy and subsequent total growth of the spine as measured by sitting height. We conclude that these children generally do not experience any major growth disturbances. 相似文献
