ObjectiveTo investigate the expression of tumor metastasis associated genes-1 (MTA1) and vascular endothelial growth factor-C (VEGF-C) in esophageal squamous cell carcinoma (ESCC) and the relationship between them and lymphangiogenesis. MethodA total of 107 patients who received excision for ESCC in the Cardiothoracic Surgery Department of Suining Central Hospital from March 2013 through January 2014 were enrolled. And the paraffinembedded esophageal tissues in 56 healthy persons were collected. The expression of MTA1 and VEGF-C in ESCC was detected using the immunohistochemical method. And D2-40 was used to label the micro-lymphatic endothelial cells of the tumor tissues while the micro-lymphatic vessel density (LVD) was counted. Meanwhile, a statistical analysis was performed for the relationship between MTA1 with VEGF-C and clinical pathological parameters. ResultsThe expression rates of MTA1 protein and VEGF-C protein in ESCC (50.4% and 58.8%, respectively) were higher than those in normal esophageal tissues with a statistical difference (P<0.05). Besides, their high expression rates in stage T3/T4 ESCC and lymph node metastasis group were significantly higher than those in stage T1/T2 ESCC and metastasisfree group, with statistical differences (P<0.05). The high expression rates of MTA1 and VEGF-C protein in ESCC with different TNM stages were compared using Kruskal-Wallis test with statistical differences (P<0.05). Moreover, a positive correlation existed in the expression level between MTA1 protein and VEGF-C protein of ESCC (Spearman coefficient r=0.512, P=0.000). And LVD of the high expression group for MTA1 protein and VEGF-C protein was statistically different from that of the low expression group (P<0.05). ConclusionThe expression of MTA1 is positively correlated with the expression of VEGF-C in ESCC. And they may co-promote lymphangiogenesis and lymphatic metastasis in ESCC. Therefore, both can be used as the laboratory indicators to determine the prognosis of ESCC.
目的：研究小鼠头颈鳞癌细胞株SCCⅦ体外放射敏感性，并探讨其与细胞周期阻滞的可能关系。方法：利用细胞克隆形成试验及MTT法检测SCCⅦ细胞受X射线照射后细胞存活能力及细胞生长趋势的变化，通过流式细胞学检测X射线照射后细胞周期分布的变化。结果：相同剂量照射后的SCCⅦ细胞存活分数高于Hela细胞（Plt;0.05）；4 Gy照射后的SCCⅦ细胞在96 h内细胞生长速度仍高于Hela细胞（Plt;0.05）；4 Gy照射后SCCⅦ细胞G1期和G2期细胞比例明显升高（Plt;0.05）。结论：SCCⅦ细胞对放射线不敏感性，放射线导致的细胞周期阻滞是SCCⅦ细胞放射抵抗的可能原因之一
目的总结原发性甲状腺鳞癌的诊治经验。方法回顾分析我院1996～2001年收治的12例原发性甲状腺鳞癌患者的临床资料。结果单纯性鳞癌4例，合并甲状腺其它疾病8例。主要临床表现为颈部包块和声嘶。单纯性鳞癌免疫组化甲状腺球蛋白染色阳性3例，阴性1例。12例患者中10例行姑息性切除者于术后1年内死亡，2例行根治性切除者存活时间超过3年。结论原发性甲状腺鳞癌呈高度恶性，可与甲状腺其它良、恶性疾病并存； 要重视对该病的诊断和鉴别诊断，免疫组化甲状腺球蛋白染色可提高确诊率； 根治性手术切除加综合治疗是提高其生存率的关键。
目的 探讨甲状腺鳞状细胞癌的临床特征和综合治疗效果。方法 回顾性分析1985年以来收治的4例原发性甲状腺鳞状细胞癌患者的临床资料。结果 单一手术的1例患者术后4个月死亡； 手术加放疗的2例患者术后6～13个月死亡； 手术加放、化疗的1例患者术后至今已两年仍存活。结论 甲状腺鳞状细胞癌系罕见的恶性肿瘤，生长速度快，术后易复发，预后差。早期行甲状腺癌联合根治术，并辅以放、化疗可降低复发机率，延长生存时间。
Abstract:Objective To investigate the clinicopathological features and prognostic aspect of basaloid squamous carcinoma （BSC）. Methods From July 2000 to May 2003, the clinical data of 1 257 documented cases that underwent potentially curative resection on esophageal carcinoma in our department were retrospectively analysed, and 18 cases of BSC （BSC group） were detected. And 54 cases of typical squamous carcinoma of esophagus（ESC） were randomly selected as control （ESC group）, to analyse the clinicopathological and prognostic parameters of BSC patients. Results The age of BSC group patients was higher than that of ESC group （61. 56 ± 7. 62 years vs. 56.11± 10. 58 years; t=-2. 012,P=0. 048）, and the ratio of T4 stage was much higher than that in ESC group （27.8% vs. 5.6%;x2= 6. 750, P= 0. 020）. The follow-up showed that, comparing with ESC group, the ratio of metastasis was higher（62.5% vs. 25.0%, P=0. 047）, and mean survival time（P〈0.05） was significantly shorter in patients of BSC group after curative resection. There were no statisticaly differences in patient gender （P = 0. 494）, or ratio of recurrence （P=0. 887） between two groups. Conclusion The BSC is a rare carcinoma involving esophagus, which occurs in elder patients. Both invasiveness and metastasis of BSC are more usual than those of typical ESC.
Objective To discuss the operative method and experience, through analyzing the medium-term and long-term effect of combined therapy for cutaneous squamous cancer of head and face. Methods From January 1998to December 2002, 37 patients with head or neck cutaneous squamous cancer received combined therapy of operation and radiation. The determination of resect area was based on the stage of the tumor, and according to the resect area and the freedom of peripheral tissue, 3 different operation procedures were adopted respectively. The follow-up was ended in June 2004. Results The follow-up was 5 to 69 months. The median follow-up interval was 38 months. Four patients (10.8%) relapsed during the follow-up, and 2 of them (5.4%) relapsed within 3 years after operation. two patients (5.4%) died from the primary affection, 4 patients (10.8%) died from other causes. According to Kaplan-Meier Method, the 3-year survival rate was 97.14% and the standard error was 0.0358, and 5-year survival rate was 92.28% and the standard error was 0.1047. Conclusion The recurrence rate of cutaneous squamous cancer of head and face witha better prognosis is lower than the ones from other origins. And the survival rate may be improved from proper operative method.
