目的:分析生殖器外纵隔生殖细胞瘤诊断和影响预后的因素。方法:65例纵隔生殖细胞瘤均行开胸手术治疗。单纯完全摘除肿瘤59例;姑息性切除1例;肿瘤摘除联合肺叶切除或胸膜纤维板剥脱术3例;开胸探查2例。恶性生殖细胞瘤术后均行辅助放、化疗。结果:良性畸胎类肿瘤手术摘除或合并肺、胸膜切除后效果良好。恶性生殖细胞瘤,尤其是精原细胞瘤切除后,辅助放、化疗仍可获得较好的远期生存。3年生存率66.7%。结论:纵隔生殖细胞瘤是常见的纵隔肿瘤,诊断后积极手术治疗可获得较好的结果。 相似文献

纵隔原发性恶性纤维组织细胞瘤 总被引:5,自引:0,他引:5
为了研究原发性纵隔恶性纤维组织细胞瘤的临床病理特点。采用常规石蜡包埋HE 染色及免疫组织化学方法研究3例MFH。3 例MFH 均位于中纵隔,肿瘤界限清楚有包膜或假包膜,术后无局部复发及转移,最长无瘤生存者已达9 a。纵隔原发MFH的病理特点与软组织MFH 相同,但局部复发率及转移率低,提示其预后好于软组织MFH。 相似文献

目的探讨原发性纵隔恶性生殖细胞肿瘤(PMGCT)的临床病理特点、治疗方法和预后因素。方法回顾性分析29例PMGCT患者的临床资料。结果29例患者均为男性,平均发病年龄26.1岁,肿瘤均来源于前纵隔,平均最大径16.0 cm。其中原发性纵隔精原细胞瘤(PMSGCT)5例(17.2%),原发性纵隔非精原细胞瘤(PMNSGCT)24例(82.8%)。PMGCT最常见症状是憋气、咳嗽与胸痛,其治疗采用化疗、手术、放疗相结合的综合治疗模式。PMNSGCT组中化生存期为19.0个月, 1年和2年生存率分别为65.3%和28.1%。PMSGCT组均长期生存,预后优于PMNSGCT组(P= 0.008)。多因素分析结果显示,病变局限于纵隔、以顺铂为基础的联合化疗是PMNSGCT患者预后的独立影响因素。结论PMGCT以PMNSGCT为主,主要治疗手段是以顺铂为基础的联合化疗。PMNSGCT预后明显差于PMSGCT,并与病变范围、化疗与否相关。 相似文献

为了探讨有内分泌功能的纵隔嗜铬细胞瘤的临床表现、定性和定位诊断、治疗措施及临床效果,回顾性分析我院诊治的5例纵隔功能性嗜铬细胞瘤,其中后纵隔肿瘤2例,中纵隔肿瘤3例。结果:5例患者术前均得到了明确的定性和定位诊断;5例患者均顺利做了肿瘤的手术切除(3例在体外循环下),术后病理得到了证实;术后所有患者的临床症状恢复正常。初步研究结果提示,手术切除是治疗纵隔功能性嗜铬细胞瘤的最佳手段,而术前明确的定位诊断是保证手术成功的关键;除传统的定位方法外,奥曲肽(99mTc-TOC)显像技术在定位诊断上更准确。 相似文献

Background
To our knowledge, no studies have evaluated the association between smoking and stage at diagnosis or survival among men with germ cell tumors (GCTs). We therefore evaluated the association between smoking and GCT presentation and outcomes.Methods
Electronic medical records of 1161 patients with GCT treated at Dana-Farber Cancer Institute between 1997 and 2013 were reviewed. Outcomes of interest were stage at diagnosis, relapse from clinical stage I (CSI) disease, relapse after first-line chemotherapy, and death from disease. Logistic regression models evaluated the association between smoking and tumor characteristics at diagnosis. Multivariable Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between smoking at diagnosis and risk of relapse and GCT cancer death.Results
In men diagnosed with CSI disease, smokers were 86% more likely to have a large tumor (≥ 4 cm) compared with nonsmokers (odds ratio [OR] 1.86; 95% CI, 1.28-2.71) and had a statistically significant increased risk of relapse (HR 2.05; 95% CI, 1.41-2.97). Among men with metastatic disease at diagnosis, the heaviest smokers (> 15 pack-years) were more likely to present with intermediate- or poor-risk disease compared with nonsmokers (OR 3.12; 95% CI, 1.29-7.55) and any smoking was associated with a statistically significant increased risk of relapse (HR 1.86; 95% CI, 1.26-2.73) and GCT death (HR 2.56; 95% CI, 1.55-4.23).Conclusion
Smoking is associated with more advanced disease at diagnosis and poorer GCT outcomes, including increased risk of relapse, for both CSI and metastatic disease. 相似文献13.
原发中枢神经系统生殖细胞肿瘤(primary central nervous system germ cell tumors,CNS GCTs)好发于儿童青少年和年轻成人。主要位于松果体和鞍上区。病理上分为胚组织瘤(germinoma)和非胚组织瘤(Nongerminoma,NGGCT),后者包括畸胎瘤、胚胎癌、内胚窦瘤和绒毛膜上皮癌。治疗前明确病理诊断对治疗方案的选择非常重要。肿瘤标记物AFP和β-HCG的检测有助于鉴别诊断。胚组织瘤主要采用放射治疗,对儿童患者可通过联合化疗减少放疗的剂量和范围。非胚组织瘤对放疗敏感性较差,需要化疗、放疗或手术等综合治疗改善生存率。CNSGCTs具有侵袭性和转移性的行为,不合适单纯采用立体定向伽玛射线(伽玛刀)治疗。针对CNSGCTs的生物学特点,采用减少不良反应保证疗效的综合治疗已取得较好的结果,值得进一步研究。 相似文献

目的:探讨纵隔非畸胎类生殖细胞瘤CT表现,并与前纵隔最常见恶性肿瘤胸腺癌行鉴别诊断分析.方法:回顾性分析病理证实且有完整临床及CT增强资料的纵隔非畸胎类生殖细胞瘤7例,分析各类纵隔非畸胎类生殖细胞瘤CT表现;同时比较7例非畸胎类生殖细胞瘤与11例胸腺癌临床及各项CT指标的差异,评估肿瘤强化均匀性,肿瘤内坏死灶情况,肿瘤内钙化,肿瘤形态,肿瘤分叶,肿瘤外侵及肺内及胸膜转移等情况CT表现对非畸胎类生殖细胞瘤与胸腺癌鉴别诊断的价值.结果:纵隔非畸胎类生殖细胞瘤均位于前上纵隔,影像表现为不均强化且含较大面积低密度坏死区域的实性肿块,边缘多模糊不清且形态不规则,就诊时肿瘤多较大且常压迫临近腔静脉及同侧肺门结构.本组非畸胎瘤类生殖细胞瘤与胸腺癌患者比较,发病年龄更年轻,非畸胎类生殖细胞瘤组患者肿瘤较胸腺癌组大,且肿瘤内密度相对较低,同时肿瘤内低密度坏死情况较胸腺癌明显.结论:多层螺旋CT增强扫描对于纵隔非畸胎类生殖细胞瘤诊断及与胸腺癌鉴别诊断有一定价值. 相似文献

The survival of children with malignant germ cell sacrococcygeal tumors has improved during the last few years after introduction of a multidrug protocol including cisplatinum. Treatment for 10 patients registered in 1965-1978 was not uniform and consisted of surgical resection or biopsy and radiotherapy with or without multiple drug chemotherapy (methotrexate + actinomycin D + cyclophosphamide). Only one of these patients is alive. Fifteen patients registered between 1978 and 1986 were treated with actinomycin D + cyclophosphamide + vincristine + doxorubicin + bleomycin + cisplatinum. Four patients also received radiotherapy. Seven out of these 15 children are alive without evidence of disease. 相似文献

Primary malignant mediastinal germ cell tumours are rare and considered to have poorer prognosis compared with those arising from gonads. Eighteen patients with primary mediastinal germ cell tumour were treated over an 11-year period; 9 had seminoma and 9 non-seminoma. Eight patients, 4 each with seminoma and non-seminoma underwent initial tumour excision and the rest had biopsy only. All patients received cisplatin-based chemotherapy. All patients with seminoma received consolidation radiotherapy to mediastinum. Three patients with non-seminoma received radiotherapy following partial response. All 9 patients with seminoma achieved complete response at the end of chemotherapy. Two patients with NSGCT had complete response to chemotherapy, 5 partial response and 2 no response. Two patients who underwent resection of the residual tumour mass are surviving free of disease. Addition of radiotherapy or second-line chemotherapy did not bring about any added response in partial and non-responders. Nine out of 9 patients with seminoma and 4/9 with non-seminoma are surviving disease-free at a median follow-up of 48 months (range 16-153 months). Mediastinal seminoma has excellent prognosis with cisplatin combination chemotherapy, whereas non-seminoma carries poor prognosis, and aggressive chemotherapy with resection of residual masses may improve the outcome. The role of additional radiotherapy and initial tumour debulking needs further evaluation. 相似文献
