  • Research Advance of Photodynamic Therapy on Cholangiocarcinoma

    ObjectiveTo understand the research advance of photodynamic therapy (PDT) on cholangiocarcinoma. MethodDomestic and international publications online which involving the research of PDT on cholangiocarcinoma in recent years were reviewed. Results①PDT was a new therapy on tumor from the tissue and cell level, which could destroy the target tissue and cell under the photochemical reaction and kill the tumor cell according to the characteristics of the selective intake of tumor tissue on particular photosensitizer. It could mainly induce tumor cell apoptosis and necrosis, destroy the tumor microvascular, stimulate the immune and inflammatory response.②PDT on the research level of the treatment of cholangiocarcinoma had achieved fairly good curative effects, which could make the tumor shrinkage, reduce the harm to normal bile duct cell, and prolong the survival, improve the survival rate and the quality of life.③Proliferating cell nuclear antigen (PCNA), vascular endothelial growth factor-C (VEGF-C), and cyclooxygenase-2 (COX-2) played important roles in the development of cholangiocarcinoma. PDT could inhibit the expressions of PCNA, VEGF-C, and COX-2, and then could promote cell apoptosis, and then inhibit cell proliferation. ConclusionsPDT is a new technology in treatment of malignant tumor, which whether used alone or combined with other methods has less adverse reaction and could obviously improve the local symptoms in treatment of cholangiocarcinoma. But many problems about PDT need to be solved at present, in the base areas, such as research and development of new photosensitizer and precise mechanism of killing tumor, in the clinical applications, such as selection and application of photosensitizer, ways and parameters of the laser, formulation of treatment plans and the reduction of the complications.

  • Comparation on Perioperative Period Situation of Laparoscopic Hepatectomy and Open Hepatectomy for Treatment of Primary Hepatic Carcinoma

    目的了解腹腔镜肝切除术(laparoscopic hepatectomy,LH)与开腹肝切除术(open hepatectomy,OH)治疗原发性肝癌的围手术期状况的变化。 方法回顾性分析2012年1月至2013年6月期间青岛大学医学院附属医院肝胆外科收治的40例原发性肝癌患者的临床资料,其中20例行LH,20例行OH,比较2组患者的术前一般情况、术中情况和术后恢复情况。 结果2组患者术前一般情况的差异均无统计学意义(P>0.05);在切口长度、术中出血量、术后肝功能指标、胃肠功能恢复情况和术后住院时间方面LH具有明显的优势(P<0.05),而在手术时间、术后并发症和住院总费用方面2组间差异无统计学意义(P>0.05)。 结论LH较传统的OH可明显改善肝癌患者的围手术期状况,值得在有条件的情况下开展推广。

  • Impact of blood glucose level after open radical hepatectomy on early recurrence of hepatocellular carcinoma

    ObjectiveTo investigate the impact of elevated fasting blood glucose (FBG) level after open radical hepatectomy on the early recurrence of hepatocellular carcinoma (HCC).MethodsThe clinical data of 112 patients with HCC who underwent the open radical hepatecomy from January 2013 to December 2014 in the Affiliated Hospital of Qingdao University were retrospectively analyzed. After the radical resection of HCC, 86 patients with level of FBG 3.9–6.1 mmol/L and 26 patients with level of FBG≥6.1 mmol/L were design into a normal FBG group and an elevated FBG group, respectively. The recurrence rates of HCC were compared between the two groups at 1- and 2-year after the opreation.ResultsThere were no significant differences between the 2 groups in the gender, age, history of alcohol drinking, hepatitis B history, preoperative ALT, AST, AFP and Child-Pugh classification, scope of hepatectomy, intraoperative hemorrhage, hepatic blood flow occlusion, diameter of maximal tumor, histopathological differentiation, tumor number, cirrhosis, satellite lesion, postoperative adjuvant TACE treatment or not (P>0.05). The postoperative 1- and 2-year recurrence rates of HCC were 19.8% (17/86) and 33.7% (29/86) in the normal FBG group and 42.3% (11/26) and 61.5% (16/26) in the elevated FBG group, respectively, showing significant differences between the 2 groups (P<0.05). The results of multivariate analysis showed that the level of FBG≥6.1 mmol/L, low histopathological differentiation, and no postoperative TACE treatment were the independent risk factors affecting tumor-free survival rate after the open radical resection of HCC (P<0.05). ConclusionsElevated FBG level after open radical resection has a stimulative effect on early recurrence of HCC. As a result, monitoring and controlling of FBG level after operation is helpful in decreasing early recurrence rate of patients with HCC.
