Objective To investigate the suitable treatment of post operative anastomotic recurrence after anterior resection of rectal cancer and analyze the relationship between different kinds of therapy with prognosis. Methods The clinical data of 41 cases of local recurrent rectal cancer after anterior resection admitted in our hospital from 1999 to 2009 were analyzed retrospectively. The median survival time and survival rate were calculated by Life Tables method. The influence of different kinds of treatment to prognosis was evaluated by Kaplan-Meier method and the variability was analyzed by Log-rank method. P <0.01 means statistical significance. Results Thirty-three (80.5 %) of 41 patients were recurrent in the first 3 years and the median survival time was 23 months. Seventeen (41.5 %) of 41 patients underwent radical R0 resection. The median survival time of radical resection patients and non-radical resection ones were 49 months and 18 months, respectively, and the difference was significant (χ2=12.245, P=0.000). Thirty-one patients with radiotherapy and/or chemotherapy showed a statistically longer median survival time than the other 10 patients without these adjuvant treatment (39 months and 9 months, respectively) (χ2=17.533, P =0.000). Conclusion Most post operative anastomotic recurrent of rectal cancer cases occurs in the first 3 years after primary surgery. Radical resection, radiotherapy and chemotherapy can improve the prognosis.

Objective To investigate the clinical features,imaging and pathologic findings of fibrolamellar hepatocellular carcinoma (FL-HCC).Methods Clinical data from 2 patients with FL-HCC confirmed by operation were analyzed retrospectively.Results There were 1 man and 1 woman,both of them were younger than 40 years.The man had hepatitis B,the woman did not have underlying hepatitis.The 2 patients had a normal hepatic function and α-fetoprotein level.Under dynamic contrast material-enhanced computed tomography,hepatic arterial phase CT images demonstrated heterogeneous enhancement of the tumor.Calcification was depicted in the CT images of 1 patients.Both of them underwent a successful operation.After 8 months of follow-up,1 patient had recurrence.And the other patient had no evidence of recurrence during 16 months follow-up time.Conclusion FL-HCC is a rare liver tumor that has distinct clinicopathologic features comparing with hepatocellular carcinoma.Most of FL-HCC occurs in young patients with normal level of α-fetoprotein and no history of hepatitis.Tumors may have calcification and become predominantly on hepatic arterial phase CT images.The most effective treatment for FL-HCC is surgical resection and prognosis is good.

Objective To investigate the clinical characteristics and analyze prognostic risk factors of combined hepatocellular-cholangiocarcinoma. Methods The clinical data of 19 cases of combined hepatocellular-cholangiocarcinoma admitted in our hospital from January 1999 to December 2009 were analyzed retrospectively. The survival function was analyzed by Kaplan-Meier. The possible prognostic risk factors were tested by χ2-test. Results Hepatocellular-cholangiocarcinoma was diagnosed by pathology in the 19 patients, among which hepatic tunic was infiltrated in 13 cases, peritoneum involved in 1 case, intravascular cancer embolus in 1 case. At that time lymphocyte nodes metastasis in 2 cases were found by regional lymphadenectomy in 7cases. The 1-year and 3-year survival rates were 61% and 42%,respectively. Prognosis of patients with tumor size > 5 cm ( χ2 = 4. 392, P = 0. 036 ), history of heavy drinking ( χ2 = 11.010, P = 0.001 ) or intraoperative blood transfusion ( χ2 = 4. 645,P = 0. 031 ) were worse than others. Conclusion It was difficult to get correct preoperative diagnosis of combined hepatocellularcholangiocarcinoma. Tumor size, history of heavy drinking and blood transfusion were all prognostic related risk factors.

Objective To review the clinical features,therapeutic approach and prognosis of hepatocellular adenoma(HCA)and liver adenomatosis(LA).Methods The clinical data from patients with histopathological diagnosis confirmed on operative specimens were analyzed retrospectively.Results There were 10 patients with HCA and 1 with LA.The disease was found mainly in females (n=7,63.6%),and only one female patient with LA had a history of use of oral contraceptive.The median age at presentation was 33 years(range,25-70 years).Most patients(n=8,72.7%)had no significant symptom.Tumor markers including CA19-9 and alpha fetoprotein(AFP)were normal.On dynamic ultrasonography,CT and MRI,most lesions showed contrast enhancement in the arterial phase and washout in the portal venous phase and delayed phase.For the 10 patients with HCA,the lesion was solitary.On histopathology,atypia and dysplasia were present in 1 patient,dysplasia in 1 patient,and active tumor cell growth in 1 patient.The patients with liver adenomatosis had multiple lesions and atypia.All patients underwent liver resection.There was no recurrence on follow-up which ranged from 21 to 125 months.Conclusions Most patients had no clinical symptoms.Hepatic steato sis may be a potential cause for HCA and LA.Oral contraceptive plays an important role in the patho genesis of LA.Dynamic imaging examinations were helpful for diagnosis.In view of the associated risks of hemorrhage and malignant transformation,surgical resection is the optimal treatment.The prognosis is good.

Objective:To analyze the effect of different vascular access on the outcome in peripheral blood stem cells collection by a network Meta-analysis, and to provide a reference for clinical medical staff to select the best vascular access.Methods:A systematic search was carried out in Chinese Knowledge Infrastructure database (CNKI), Wanfang Database, VIP Database, Chinese Biomedical Literature Database, Cochrane Library, Web of Science, PubMed, Embase, from inception until April 15, 2023. Two researchers independently screened literature and extracted data. Bayesian network meta-analysis was performed using R4.2.2 and Addis-1.16.6 softwares.Results:A total 7 pieces of research were included, 5 vascular access methods were peripheral artery, peripheral vein, artery-vein, femoral vein-central venous catheter (FV-CVC), and internal jugular vein-CVC (IJV-CVC). The results showed that compared with the peripheral veins, there was no significant difference on CD34 cells between other vascular accesses in the primary outcome measure when collected peripheral blood stem cell collection. On the single blood volume treatment time, peripheral vein and IJV-CVC were statistically significant ( MD = 14.80, 95% CI 2.70-22.38, P<0.05) . The SUCRA ranking probability chart showed that on CD34 cells, FV- CVC>IJV-CVC>artery-vein>peripheral artery>peripheral vein access; for a single blood volume treatment time and monocyte number, peripheral artery was superior and the next was peripheral vein. Conclusions:Current evidence suggested that Peripheral artery may be the best vascular access in peripheral blood stem cells collection, which opens a new way to establish the vascular access for peripheral blood stem cells collection, but it needs to be confirmed by large clinic trials.
