Objective To investigate the value of thyroid stimulating hormone (TSH) inhibition therapy in postoperative patients with differentiated thyroid carcinoma. Methods One hundred and six patients with differentiated thyroid carcinoma after total or near-total thyroidectomy were divided into two groups: TSH inhibition therapy group and thyroid hormone replacement therapy group. The non-recurrence and (or) non-metastasis rate in two groups was analyzed retrospectively by Wilcoxon statistical analysis. Results The non-recurrence and (or) non-metastasis rate of 3-， 5- and 10-year in TSH inhibition therapy group were 98.31%， 92.41% and 75.45% respectively， and were higher than those (93.57%， 84.18% and 52.06% respectively) in thyroid hormone replacement therapy group （P=0.046 5）. Conclusion TSH inhibition therapy after total or near-total thyroidectomy may be an essential treatment for differentiated thyroid carcinoma patients.
ObjectiveTo investigate the values of serum CEA and CA19-9 in predicting postoperative recurrence and metastasis and prognosis for gastric cancer. MethodsPreoperative serum levels of CEA and CA19-9 were measured by electrochemiluminescence assay in 136 patients with gastric cancer. The relationships of serum CEA level, CA19-9 level to clinicopathologic features, postoperative recurrence and metastasis, and prognosis of gastric cancer were analyzed. Kaplan-Meier method (log-rank test) was used to survival analysis. ResultsThere were 67 patients with postoperative recurrence and metastasis in 136 patients with gastric cancer. The positive rate was 48.5% (66/136) for CEA and 43.4% (59/136) for CA19-9. There was a significant correlation between CEA level and T stage, TNM stage, lymph node metastasis, or vascular invasion (P=0.011, P=0.018, P=0.021, P=0.024). There was a significant correlation between CA19-9 level and T stage or lymph node metastasis (P=0.018, P=0.045). The rate of postoperative recurrence and metastasis was 60.6% (40/66) in positive CEA, 61.0% (36/59) in positive CA19-9, 38.6% (27/70) in negative CEA, and 40.3% (31/77) in negative CA19-9, respectively. The rate of postoperative recurrence and metastasis in the positive CEA or positive CA19-9 was significantly higher than those in the negative CEA or negative CA19-9 (P=0.010, P=0.016). Kaplan-Meier analysis showed that patients with positive CEA or positive CA19-9 had worse survival than those with negative CEA or CA19-9 (P=0.003, P=0.007). ConclusionsCEA and CA19-9 have important values in detecting recurrence and metastasis, predicting patient survival after gastric cancer surgery. Combined analysis of these markers is considered to be helpful for improving the prediction of the postoperative recurrence and metastasis and prognosis of gastric cancer.
ObjectiveThe risk factors of relapse in 133 epileptic children after withdrawal were analyzed retrospectively and provide reference for clinical withdrawal.MethodsFrom January 2017 to March 2019, 133 children with withdrawal epilepsy were selected as the study object. According to whether there was recurrence during the follow-up period, the children with epilepsy were divided into recurrence group (42 cases) and non recurrence group (91 cases). The gender, age of onset, history of trauma, frequency of seizure before treatment, EEG before drug reduction, imaging, type of medication, family history, time of reaching control, course of disease before treatment, comorbidity, multiple attack types, withdrawal speed and EEG before treatment were observed and compared between the two groups. ResultsThere were significant differences in EEG (χ2 =7.621), medication type (χ2=8.760), time to control (χ2=6.618), course before treatment (χ2=6.435), multiple seizure types (χ2=5.443) and epilepsy comorbidity (χ2=42.795) between the two groups (P < 0.05). The results of Logistic multiple regression analysis showed that the recurrence of epileptic children after drug reduction / withdrawal was correlated with abnormal EEG before drug reduction [OR=9.268, 95%CI (2.255, 38.092)], combined drug treatment [OR=3.205, 95%CI (1.159, 8.866)] and course of disease > 1 year before treatment [OR=5.363, 95%CI (1.781, 16.150)] (P < 0.05).ConclusionsIn order to reduce the possibility of recurrence of epileptic children, the treatment time of epileptic children with abnormal EEG, combined medication and long course before treatment should be prolonged properly.
Objective To systematically review the diagnostic value of 18F-FDG PET/CT in recurrent epithelial ovarian cancer after treatment. Methods The PubMed, EMbase, Cochrane Library, Web of Science, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect diagnostic tests of 18F-FDG PET/CT for epithelial ovarian cancer from inception to February 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Meta-Disc 1.4 and Stata 15.0 software. Results A total of 15 studies involving 792 patients were included in this study. The results of meta-analysis showed that the sensitivity, specificity, and area under the curve of 18F-FDG PET/CT in the diagnosis of recurrent epithelial ovarian cancer were 0.88 (95%CI 0.85 to 0.90), 0.80 (95%CI 0.75 to 0.85) and 0.91, respectively. The results of the subgroup analysis showed that the sensitivity of the prospective studies was the same as that of the retrospective studies, but the specificity of the prospective studies was higher than that of the retrospective studies. The diagnostic sensitivity and specificity of 18F-FDG PET/CT in recurrent epithelial ovarian cancer were higher in Asian studies than in European/North American studies. Conclusion 18F-FDG PET/CT has high diagnostic value in recurrent epithelial ovarian cancer. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To summarize the role of the relationship between liver cancer and cellular immunological function, and the role of immune therapy in clinical application. Methods To analyze the relationship between liver cancer and cellular immunological function, and the present research situation of immune therapy for liver cancer in clinical application retrospectively via review the related domestic and foreign literatures. Results The cellular immune dysfunction existed in all liver cancer patients. The state of body’s cellular immunological function is closely related with the arising and development of liver cancer, and the lowness of cellular immunological function is an important factor of hepatocellular carcinoma hard to cure or recurrence and metastasis. Immune therapy plays an important role in the treatment of liver cancer by adjusting the body’s cellular immunological function. Conclusions Liver cancer is closely related with the body’s cellular immunological function. Immune therapy is expected to offer a new way for the treatment of liver cancer, which can also be used as an important auxiliary treatment way.
Objective To discussion the diagnostic significance of CT three dimension reconstruction in local recurrence after surgery for gastric cancer. Methods Thirty-nine patients with gastric cancer recurrence after radical surgery were performed multislice CT scan between December 2004 and December 2008 in The Third Affiliated Hospital of Harbin Medical University, and the images were reconstructed by three dimension reconstruction in workstation. The axial CT images and three dimension images of gastric cancer recurrence patients were diagnosed and compared. Results The detection rates of axial images and three dimensional CT images were 82.1% (23/28) and 100% (28/28) for pathological morphology, 62.5% (10/16) and 93.8%(15/16) for extension of tumors, 66.7% (10/15) and 93.3% (14/15) for lymph node metastasis, 87.5% (7/8) and 87.5% (7/8) for distant metastasis, respectively. Conclusions CT three dimension reconstruction can carry out more direct and solid results, such as measuring the vertical thickness of the thickened gastric wall, observing the infiltration situation with proximal organ, and metastasis of the lymph node. The method of three dimension reconstruction used for the diagnosis of local recurrence after surgery for gastric cancer is better than the axial image, and it can supply data which would be useful for the tumor advancing treatment.
Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P＜0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%， 79.2% vs. 78.0%，Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.
Objective To evaluate the outcome of liver transplantation in patients with recurrent liver cancer after resection. Methods Data of 23 patients underwent liver transplantation for recurrent liver cancer from April 2001 to March 2008 were retrospectively collected and analyzed. Results Previous history of liver resection had little negative effect in subsequent liver transplantation in technical aspect. Liver function recovered uneventfully after transplantation in all cases. Alpha fetoprotein (AFP) recovered to normal value in 13 of 17 cases with elevated AFP before transplantation within one month after operation. Five cases (21.74%) had postoperative complications. Nineteen cases (82.61%) were followed up, average follow-up duration were 610 days. There were 5 cases (26.32%) of cancer recurrence and 6 deaths during follow-up, survival rate was 68.42%. Conclusion Liver transplantation is a reasonable treatment for recurrent liver cancer after resection.
ObjectiveTo explore the relationship between liver transplantation procedure with or without preservation of retrohepatic vena cava and postoperative reinfection of hepatitis B virus.MethodsHepatitis B virus makers of 15 retrohepatic vena cava samples from hepatitis B virus active replicating recipients was detected using immunohistochemistry stain LSAB and HBV DNA hybridization in situ. Hepatitis B virus reinfection rate and survival rate after transplantation in classic group (20 cases) and piggyback group (7 cases) was analyzed retrospectively. ResultsHepatitis B virus makers including HBsAg and HBcAg and HBV DNA of all 15 retrohepatic vena cava samples, 10 from classic group and 5 from piggyback group, was negative. In classic group, 20 recipients were followedup 6-30 months, mean 18 months, only one case of hepatitis B recurrence was confirmed 22 months after operation; In piggyback group,7 recipients were followedup 5-12 months, mean 8 months, none of hepatitis B virus reinfection was encountered. Recurrence rate in classic group and piggyback group was 5.0%(1/20) and 0(0/7), respectively.ConclusionThis preliminary study indicated that the retrohepatic vena cava of hepatitis B virus active replicating recipients don’t have the residence and replication of hepatitis B virus particle. Orthotopic liver transplantation procedure with preservation of retrohepatic vena cava appears not to increase the hepatitis B virus reinfection rate in hepatitis B virus active replicating recipients after transplantation.
Objective To evaluate the prognostic and pathobiologic significance of DNA content. Methods DNA content was conducted on 140 hepatocellular carcinoma patients by flow cytometry. Cancer recurrence was followed up after the patients were discharged. The statistical software used was SPSS. Results DNA ploidy did not correlate with clinicobiologic features, except with the age of the patients (Ｐ＜0.05), tumor size and AFP level (Ｐ＜0.01). The mean following up time of the patients with diploid was 31.2 months. The recurrence rate was 23.1%. In aneuploid group the mean following up time was 22.6 months. The recurrence rate was 50.0%. Ploidy correlated significantly with recurrence rate, the recurrence rate for patients with aneuploid were significantly higher than for those of diploid (Ｐ=0.013), also the recurrence rate of aneuploid within one year (37.9%) was much higher than that of diploid (4.3%) Ｐ=0.002. In a Logistic multivariate analysis of DNA content, the grade of cirrhosis severity and the tumor size were considered to be independent factors that related with recurrence. Conclusion FCM DNA analysis of radically resected HCC is a simple and valid method to predict the recurrence.
