A highly metastatic giant cell carcinoma (PG) and a poorly metastatic adenocarcinoma (PAa) were orthotopically implanted into nude mice, and the take rates were 74% for PG and 56% for PAa. Invasive tumors located in hilar region or peripheral part of lung, or spread diffusely, which were quite similar to three macroscopic types of primary lung carcinomas and different from well-circumscribed masses of ectopically implanted tumors. It is interesting to point out that the metastatic incidence of PAa cells in regional lymph nodes was 56% when implanted orthotopically which was even higher than the metastatic incidence in beige nude mice bearing subcutaneous tumors. Collectly, the results demonstrate that the orthotopic implantation of human lung carcinomas favour the expression of metastatic phenotype suitable for experimental study of metastasis. The comparation of expressions of oncogenes and antioncogenes in orthotopically implanted tumors with those in subcutaneously implanted tumors of the same kind will contribute to searching for molecular basis of tumor invasion and metastasis.

将高转移人肺巨细胞癌和低转移人肺腺癌常位移植于裸鼠肺内,其移植成功率分别为74%和56%,肺内移植瘤仍保持人原发肿瘤的病理组织学形态,其肉眼类型可呈肺门肿块,周围结节和弥散浸润型,与人类原发肺癌亦相似,而与局限膨胀生长或较少浸润的裸鼠皮下移植瘤有明显区别。肺内常位移植瘤较广泛地浸润胸部脏器,特别应当指出的是低转移肺腺癌细胞肺内移植其淋巴结转移率可达56%,甚至高于该癌系在beige裸鼠体内的淋巴结转移率。说明常位移植有利于恶性肿瘤表达其浸润转移表型。常位移植之肿瘤生物学行为更接近人体内原发性肿瘤的生物学行为,将成为研究人类肿瘤特性和实验治疗的更为适宜的实验模型。研究裸鼠皮下移植瘤和常位移植瘤基因表达的差异亦将为肿瘤浸润转移分子生物学基础的揭示作出贡献

This paper reports on immunohistochemical analysis for p53 protein and PCNA expression in 34 patients with squamous cell lung carcinomas whose tissue sections contained adjacent normal epithelium and/or precancerous lesions. Nuclear p53 protein was present in 0 of 12 normal mucosae, 0 of 14 squamous metaplasias,2 of 13 mild dysplasias,7 of 17 moderate dysplasias,12 of 21 severe dysplasias, 5 of 9 carcinomas im situ, and 24 of 34 invasive tumors, while PCNA labelling index was 6.5±3.3, 9.4±4.7, 12.5±8.7, 43.3±14.9, 68.1±9.1, 74.6±8.2 and 65.4±23.6 resPectively in the above-metioned lesions. With the Progress of bronchial lesions from mild dysplasia to severe dysplasia to carcinoma in situ and invasive carcinoma, the immunostained cells of p53 and PCNA increased in number and appeared In the upper cell layers of the epithelium. These findings indicate that p53 protein expression is detectable in precancerous bronchial lesions and suggest that routine assay of p53 protein and PCNA expression may be valuable for the early diagnosis of squamous cell lung carcinotma.

应用免疫组织化学方法在含有肺鳞癌及其癌前病变的标本上观察了P53蛋白和PCNA在肺鳞癌发生过程中出现表达的时间和频率。结果在癌旁正常和鳞状化生的支气管上皮未见p53蛋白表达,在轻→中→重度不典型增生、原位癌、浸润癌、p53蛋白表达的阳性率逐渐升高,阳性细胞也逐渐增多。在p53阳性的不典型增生的支气管上皮,其相应的鳞癌p53蛋白也呈阳性。PCNA的表达也呈现上述特点,但出现表达的时间早于p53蛋白。结果表明p53蛋白和PCNA可作为判断肿瘤发生可能性的有用的标志物,在肺鳞癌的早期诊断中具有重要意义。
