Chemokine receptor CCR6 as a prognostic factor after hepatic resection for hepatocellular carcinoma

Background and Aims: Chemokines and their receptors have recently been shown to have major roles in cancer metastasis. The aim of this study was to determine whether the interaction between chemokine receptor 6 (CCR6) and its ligand, macrophage inflammatory protein‐3 alpha (MIP‐3α), correlates with metastasis of hepatocellular carcinoma (HCC). Methods: To observe the reaction of CCR6 expressed cancer cells to MIP‐3α stimulation, chemotactic and actin polymerization assays for both CCR6 high cells (HepG2) and CCR6 low cells (MCF‐7) were performed. CCR6 mRNA levels in tumor specimens from 30 HCC patients were quantified by real‐time polymerase chain reaction. Patients were classified into two groups, high (≥ 20 copies; n = 10) CCR6 and low (<20 copies; n = 20) CCR6 on the basis of CCR6 expression, and the groups were compared with respect to clinicopathological features. Results: When HepG2 cells (CCR6 high) were stimulated with MIP‐3α, they migrated in a dose‐dependent manner, and formation of pseudopodia was observed. These phenomena were not observed in the CCR6 low cells. The incidence of intrahepatic metastasis was higher in the high CCR6 expression group than in the low CCR6 expression group (P < 0.05). Disease‐free survival was significantly poorer in the high CCR6 expression group than in the low CCR6 expression group (P < 0.05). Conclusions: It was indicated that CCR6 might be associated with intrahepatic metastasis of HCC and might be able to become one of the prognostic factor after hepatic resection for HCC.

Laparoscopic splenectomy for isolated parenchymal splenic metastasis of ovarian cancer

Metastatic carcinoma of the spleen occurs in a setting of widespread malignant disease. Solitary parenchymal splenic metastasis of ovarian carcinoma is rare. We report a case of a 59-year-old woman who presented with an elevated serum CA125 level due to a solitary splenic metastasis after a long disease-free period. She was treated with laparoscopic splenectomy followed by chemotherapy. The literature contains 16 cases of solitary parenchymal splenic metastasis of ovarian carcinoma. Our case is the third case that was treated with laparoscopic splenectomy. We review the literature, and we focus on the laparoscopic approach in managing these cases.     

放射治疗骨转移癌疼痛47例临床分析

结肠癌淋巴结转移状况对结肠癌根治术D3式淋巴结清除预后的影响

目的探索结肠癌淋巴结转移情况与术后生存率以及病理参数之间的关系,寻找评价预后的简单有效指标。方法回顾性分析了174例淋巴结转移的中晚期结肠癌住院资料和随访结果,调查了根治术D3式淋巴结清除术的阳性淋巴结率以及淋巴结转移阳性个数,以及术后生存率和病理参数特点。结果结肠癌根治术 D3式淋巴结清除术后总体5年生存率为35.6%(62/174)。阳性淋巴结率在1%~20%的5年生存率70.7%(29/41),大于20%的5年生存率为23.3%(31/133),两者之间存在显著性差异(P<0.05)。全组淋巴结转移阳性个数为(6.3±2.5)个,1~5个阳性淋巴结的5年生存率为66.0%(31/47),6~10个阳性淋巴结的5年生存率为28.8%(19/66),大于10个阳性淋巴结的5年生存率为19.7%(12/61),3组之间存在显著性差异(P<0.05)。阳性淋巴结率以及淋巴结转移阳性个数与肿瘤部位无关。和瘤体直径介于0~4.0cm相比较,>4.0cm肿瘤的阳性淋巴结率以及淋巴结转移阳性个数明显增加(P<0.05)。和局限于黏膜的肿瘤相比,浸润肌层或穿透浆膜后,阳性淋巴结率以及淋巴结转移阳性个数明显增加(P<0.05),而肿瘤浸润肌层和穿透浆膜之间不存在差异。结论准确计算阳性淋巴结率及淋巴结转移阳性个数,结合肿瘤浸润深度来评定结肠癌病人的预后是一种简单有效的方法。     

MACS检测胃癌腹腔冲洗液游离癌细胞的研究

目的 探讨胃癌腹腔微转移情况的检测方法及意义。方法 手术中切除肿瘤前收集腹腔冲洗液，采用磁激活细胞分离术（MACS）对不同病理分期胃癌患者腹腔冲洗液中癌细胞进行富集并检测。分别标记带磁珠的细胞角蛋白（CK）抗体，经磁柱富集CK^＋上皮细胞，用流式细胞仪检测其含量，并比较胃癌组与胃平滑肌瘤组（对照组）以及胃癌不同分期之间、磁富集前后CK^＋上皮细胞含量的差异。结果 在未经MACS富集的标本中较少发现CK^＋ CD45^-细胞；在富集后的标本中其含量在胃癌组与对照组有显著差异（41／50，1／10，P〈0．001）；pTNMⅠ～Ⅱ期与Ⅲ～Ⅳ期之间（0．67％，3．42％，P〈0．001）差异有非常显著性。结论 MACS能有效地富集上皮来源细胞，提高上皮源细胞的检出率，并能反映腹腔游离癌细胞数量；上皮细胞数量与胃癌的存在及临床病理分期有关，其有利于判断肿瘤转移和预后并指导治疗。     

大肠癌肝转移射频消融后局部复发影响因素的分析

目的 探讨射频消融（radiofrequency ablation,RFA）治疗大肠癌肝转移后局部肿瘤复发的风险因素。方法 回顾性研究213例347个肿瘤实施RFA治疗后局部复发的临床资料,对可能影响RFA局部治疗效果的临床因素进行统计学处理。结果 175例（82.2%）298个肿瘤（85.9%）得到CT或MRI随访资料。大肠癌肝转移灶RFA后肿瘤局部复发率为36.9%（110/298）,局部复发的平均时间为16.4月（2～57个月）。单因素分析显示肝脏转移灶的部位、大小和射频针类型与肿瘤射频后的局部复发相关（P值分别为P=0.000,P=0.021和P=0.026）,但Cox多因素分析则显示只有瘤大小和转移灶部位是大肠癌肝转移射频消融后局部复发的独立预后因素（χ^2=8.522,P=0.000;χ^2=1.321,P=0.022）。结论 肝脏肿瘤的大小和部位是RFA治疗效果的独立影响因素,正确的电极选择和布针是获得肿瘤完全坏死的关键。

腹膜透析患者应对压力的方式与焦虑抑郁情绪的关系

目的：探讨应对压力的方式与腹膜透析患者的焦虑抑郁情绪的关系。方法：采用自填式结构问卷，对81例腹膜透析患者进行调查，了解患者的一般情况和患者应对措施，同时用综合性医院焦虑和抑郁情绪量表测量他们的焦虑与抑郁情绪。结果：控制年龄等因素后的等级回归分析表明：使用“面对”和“自我缓解”应对方式显著降低患者的焦虑情绪，采用“屈从”应对方式增加焦虑的发生；文化程度高的患者采用逃避应对方式则大大增加焦虑情绪的程度，女性和经济收入高者采用面对应对方式可以大大降低焦虑情绪的发生；“自我缓解”应对方式显著降低患者抑郁情绪发生的可能性。结论：不同的应对方式对腹膜透析患者的焦虑抑郁情绪存在差异。
