Germ cell neoplasms are the most common types of testicular neoplasm
生殖細胞腫瘤是睪丸腫瘤中最常見的類型。Apart from the gonads, the mediastinum is the most frequently involved site of germ cell tumors, accounting for about 2 - 6 % of these neoplasms
摘要除了性腺外,縱膈腔是生殖細胞瘤最好發的位置約佔百分之二至六。Most teratomas of the mediastinum are benign and only 15 - 20 % account for malignant neoplasms, such as immature teratomas, mature teratomas with malignant transformation, or teratomas concomitant to mixed germ cell tumors
大部分縱膈腔畸胎瘤是良性的,百分之十五至二十是惡性腫瘤,如不成熟畸胎瘤、成熟畸胎瘤並惡性轉形、畸胎瘤共存的混合生殖細胞瘤。Methods : sixty five patients with mediastinal seminomas were performed with open thoracic operation
方法65例縱隔生殖細胞瘤均行開胸手術治療。All patients were administrated by adjuvant radiotherapy or and chemotherapy after malignant seminomas resection
惡性生殖細胞瘤術后均行輔助放、化療。Objective : to analyse clinical diagnosis and prognostical factors of non - genital mediastinal seminoma
摘要目的:分析生殖器外縱隔生殖細胞瘤診斷和影響預后的因素。An endodermal sinus tumor ( yolk sac tumor ) of the testis is shown composed of primitive germ cells that form glomeruloid or embryonal - like structures
睪丸的內胚層竇腫瘤(卵黃囊腫瘤)由原始生殖細胞構成,這些細胞形成血管球或胚芽樣結構。Studies of the crystal structure of endostatin have shown a compact globular fold, with one face particularly rich in arginine residues acting as a heparin - binding epitope, this site was recently shown to be involved in the inhibition of induced angiogenesis. experimental studies show that recombinant endostatin specifically inhibits the proliferation of endothelial cells in a dosedependent fashion. recombinant endostatin from bacteria is largely insoluble, but still efficient in arresting tu mor growth after injection into mice. intermittent therapy with recombinant bacterially produced endostatin reduces several experimental tumors, including lewis lung carcinoma, to a dormant state. no sign of drug induced resistance has been reported and, in the original study, the treatment dormancy appeared to persist even when therapy was discontinued. sowe regard endostatin as a promising anti - tumor drug
許多研究表明重組內皮抑素特異性抑制內皮細胞增殖,而且這種抑制作用呈劑量依賴性。細菌表達產物內皮抑素大部分以不溶形式存在,將這種混懸液注射治療老鼠仍可以抑制腫瘤生長。于小鼠皮下重復注射內皮抑素重組蛋白,幾乎完全抑制鼠lewis肺癌等多種腫瘤生長,並無耐藥性產生,即使中斷治療腫瘤也不再復發。Primary mediastinal germ - cell tumors ( gcts ) without gonadal involvement are rare and can be divided into benign mature teratoma and malignant seminoma or nonseminoma
摘要無生殖腺體侵犯之原發性縱膈腔生殖芽細胞腫瘤為罕見之腫瘤,一般分為良性成熟畸胎瘤及包含精細胞瘤和非精細胞瘤在內的惡性腫瘤。Mutation can also occur in cells other than germ cells - somatic mutation ? but this is likely to be apparent only when the genetically altered cell proliferates abnormally to form a large family or clone of similar cells, e. g. when a tumour forms
突變也可發生於生殖細胞以外的細胞(體細胞突變) ,但這很可能僅表現于遺傳性改變的細胞異常增生而形成一大系或克隆的相似的細胞時,例如當一個腫瘤形成時。Intracranial embryonal carcinoma is a rare germ cell tumor found predominantly in the pineal region and, to a lesser extent, in the suprasellar region
摘要顱內胚胎瘤是一種少見的生殖細胞瘤,而且大多好發于顱內松果腺區域或上蝶鞍部。Four malignant gcts ( 1 seminoma, 1 choriocarcinoma, and 2 yolk - sac tumors ) have been treated in our hospital
共有包括一位精細胞瘤、一位絨毛膜癌及兩位卵黃囊瘤在內的四位惡性生殖芽細胞腫瘤的病人于本院治療。We describe our experience of malignant mediastinal gcts and compare the presentations and outcome with those of benign teratomas
在此我們報告惡性縱膈腔生殖芽細胞腫瘤之病患,並和成熟畸胎瘤比較其臨床表現和預后。Compared with the nine cases of benign teratomas, the four malignant gcts showed overwhelming male dominance, advanced symptoms at presentation, and poor outcome
和其他九位成熟畸胎瘤病人比較,惡性生殖芽細胞腫瘤的病人有顯著的男性病患傾向,明顯的癥狀及較差的預后。Recent reports showed that telomerase activity in s. cerevisiae cells could be significantly up - regulated after exposure to some dna - damaging agents, which may be related with dna - damage repair
端粒酶與細胞生長、繁殖、衰老及腫瘤的發生密切相關。近來研究發現,釀酒酵母經dna損傷劑作用後端粒酶活性升高,可能與端粒dna損傷后修復機制有關。For example, as a direct toxic effect, periodontal iruses and bacteria and their products ( endotoxins or enzymes, for example ) are toxic to surrounding cells and may directly induce mutations in tumor suppressor genes and proto - oncogenes or alter signaling pathways that affect cell proliferation or surial of epithelial cells
例如,作為直接毒性作用,牙周病毒和細菌及在細胞周圍其產生的毒性物質(例如,類毒素或酶類)可直接誘導腫瘤抑制基因和原癌基因突變或者改變細胞信號傳導通路從而影響上皮細胞增殖或存活。It was sure to get good survival after malignant seminoma, special germ cell tumor resection and assistant radiotherapy or and chemotherapy 66. 7 % in 3 - y sicrvival
惡性生殖細胞瘤,尤其是精原細胞瘤切除后輔助放、化療仍可獲得較好的遠期生存。Progress of intraoperative brachytherapy using radioactive seeds plaque implants for tumor
顱內生殖細胞瘤的放射治療Telomerase is a celler reverse transcriptase which catalyzes the synthesis and extension of telomeric dna. telomerase activation is not observed in normal tissues of somatic origin but in almost 90 % of human cancer, with the result the telomere shorten progressively with cell division and thus is a critical step for multistep carcinogenesis
正常人體細胞(非生殖細胞)中端粒酶活性的表達很低,或用目前的方法幾乎檢測不到,而在90以上的惡性腫瘤中可檢測到端粒酶活性,相應的良性腫瘤則為陰性或僅有少數陽性。It is able to get better results when the seminoma resected actively after determining the diagnosis
結論:縱隔生殖細胞瘤是常見的縱隔腫瘤,診斷后積極手術治療可獲得較好的結果。分享友人
