ABSTRACT
Objective To explore the safety and feasibility of microwave ablation assisted laparoscopic resection of liver cancer.Method The clinical data of 40 patients with liver cancer were retrospectively analyzed from April 2013 to June 2016 in Shengjing Hospital.Results Procedures were completed successfully without conversion to open laparotomy or serious complications.The average operation time,blood loss and postoperative hospital stay were (160 ± 68) min,(36 ± 27) ml and (7.6 _± 2.7) d,respectively.There was no tumor recurrence in surgical margins.The postoperative median tumor-free survival was 30 months,with cumulative 1-year and 2-year tumor-free survival rates of 89.4％ and 65.5％,respectively.The postoperative median overall survival time was 38 months,with cumulative 1-year and 2-year survival rates of 100％ and 90.9％,respectively.Conclusion Microwave ablation can effectively control intraoperative bleeding,and prevent tumor recurrence in surgical margins.Microwave ablation assisted laparoscopic hepatectomy is safe and feasible for hepatocellular carcinoma.
ABSTRACT
Objective To study the clinicopathological features and biological behavior of inflammatory pseudotumor-like follicular dendritic cell tumor.Methods We studied the clinical data,HE sections,immunohistochemical staining,Epstein-Barr virus encoded nuclear RNA(EBER)in situ hybridization and outcome of one patient with inflammatory pseudotumor-like follicular dendritic cell tumor of liver,and thirteen patients with inflammatory pseudotumor of liver and spleen treated at the Shengjing Hospital of China Medical University from 2001 to 2010.Results Among the thirteen inflammatory pseudotumors,we diagnosed 1 patient with inflammatory pseudotumor-like follicular dendritic cell tumor of spleen and 1 patient with inflammatory pseudotumor-like follicular dendritic cell tumor of liver using immuno-histochemical staining and EBER in situ by hybridization.The liver case had pathological morphology consistent with those described in the literatures,but the splenic case had specific histologic features.They were both female,and were alive 2.5 and 6 years after operation.Conclusions Inflammatory pseudotumor-like follicular dendritic cell tumor should be distinguished from inflammatory pseudotumor.It is a rare tumor seen mainly in liver and spleen.The diagnosis depends on histopathological and immunohistochemical findings.Inflammatory pseudotumor-like follicular dendritic cell tumor is a low-grade malignant tumor.Surgical excision is the treatment of choice.The two cases provided evidence for its indolent behavior.
