Objective:To evaluate the predictive value of simplified geriatric assessment (sGA) in elderly Chinese patients diagnosed with diffuse large B-cell lymphoma (DLBCL) .Methods:It retrospectively analyzed the relationships of sGA with the clinical characteristics, outcome, and prognosis of 219 patients aged ≥60 years who were newly diagnosed with DLBCL at six hospitals in Jiangsu province between January 2018 and December 2022.Results:The median age of 219 patients was 68 years (60-87 years). According to the sGA system criteria, 101 (46.1%), 103 (47.0%), and 15 (6.8%) elderly patients with DLBCL were categorized as fit, unfit, and frail, respectively. The most common adverse reactions after chemotherapy were hematologic, and the incidence of grade >2 hematologic adverse reactions was similar among the three groups (47.5% vs 41.7% vs 46.7%, respectively; χ2=0.712, P=0.700). Compared with the fit and unfit groups, the frail group showed tendencies toward for higher proportions of grade >2 gastrointestinal, pulmonary, and infectious adverse reactions ( P>0.05 for all). The fit, unfit, and frail groups had respective remission rates of 74.3%, 46.6%, and 20.0% ( χ2=25.249, P<0.001) ; disease progression rates of 5.9%, 11.7%, and 26.7% ( χ2=6.763, P<0.05) ; 2-year overall survival rates of 92.1% (95% CI 86.6% to 97.9%), 77.6% (95% CI 69.5% to 86.6%), and 70.1% (95% CI 49.4% to 99.6%) ( P<0.05) ; and 2-year progression-free survival rates of 76.8% (95% CI 67.0% to 84.8%), 69.7% (95% CI 61.8% to 82.0%), and 65.7% (95% CI 53.3% to 100%) ( P=0.399) . Conclusion:sGA can effectively predict treatment adverse effects and efficacy, disease progression, and long-term survival in elderly DLBCL.

Objective:To study the impact of early blood concentrations of tacrolimus on the survival of patients after liver transplantation.Methods:Clinical data of 159 patients with liver diseases undergoing classic orthotopic liver transplantation at the Department of Hepatobiliary Surgery, the 900th Hospital of the Joint Logistics Support Force between January 2010 and December 2019 were retrospectively analyzed, including 123 males and 36 females, aged (48.0±12.2) years. According to survival status, patients were divided into the surviving group ( n=108) and death group ( n=51). Inverse probability of treatment weighting (IPTW) was applied to adjust for confounding factors by weighting covariates between the two groups. Univariate and multivariate Cox regression analysis were used to examine the relationship between early tacrolimus concentrations and mortality, and restrict cubic spline (RCS) curves were employed to assess the nonlinear relationship further. Results:After IPTW weighting, multivariate Cox regression analysis indicated that early tacrolimus concentration ( HR=2.479, 95% CI: 1.354-4.537, P<0.001) and preoperative international normalized ratio ( HR=0.358, 95% CI: 0.162-0.792, P=0.011) levels were risk factors for post-transplant survival. The RCS curve revealed that the optimal thresholds for early tacrolimus concentration were 6.30 ng/ml and 8.28 ng/ml ( P<0.001). Patients were therefore divided into the optimal concentration group ( n=60) and the non-optimal concentration group ( n=99). After IPTW weighting, the optimal concentration group comprised 102 cases, and the non-optimal concentration group included 212 cases. The 1-year, 3-year and 5-year survival rates in the optimal concentration group and the non-optimal concentration group were 97.06%, 81.37% and 75.49%, and 86.32%, 64.62% and 50.94%, respecitvely ( χ2=8.37, P<0.001). Conclusion:Early tacrolimus concentration is an independent risk factor for post-transplant survival. A tacrolimus concentration >8.28 ng/ml or <6.30 ng/ml is associated with a relatively higher mortality rate.

Hepatolenticular degeneration is kind of an autosomal recessive genetic disease with diverse, complex and non-specific clinical manifestations, high misdiagnosis rate, rapid disease progression, poor drug treatment effect, and high mortality. It is one of the rare several genetic metabolic diseases in clinic that could be cured by liver transplantation method. Liver transplantation provides healthy P-type ATP enzyme through the donor liver, which can correct its genetic defects, improve copper metabolism disorders, relieve clinical symptoms, improve the quality of life, and improve the survival rate of patients. Liver transplantation is playing an increasingly important role as an important means to treat hepatolenticular degeneration. With the rapid development of partial living donor liver transplantation, auxiliary liver transplantation, domino-assisted liver transplantation and cross-assisted domino liver transplantation, a new way has been provided for patients with hepatolenticular degeneration, alleviating the problem of donor liver shortage and shortening the waiting time of recipients, which has certain clinical value and development prospects. In this paper, a review of the research progress in the treatment of hepatolenticular degeneration with liver transplantation was made with reference to the relevant literature at home and abroad.

Objective:To investigate the predictive value of preoperative γ-glutamyl transferase/lymphocyte count ratio (GLR) levels for postoperative tumor recurrence in liver transplant recipients with liver cancer.Methods:The clinical data of 158 recipients who were diagnosed with hepatocellular carcinoma (hereinafter referred to as liver cancer) and received liver transplantation at the No. 900 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2008 to October 2022 were retrospectively analyzed. X-tile software, the Kaplan-Meier method, univariate and multivariate Cox regression, and other statistical methods were performed. The predictive value of preoperative GLR levels for postoperative tumor recurrence in liver transplant recipients with liver cancer and the risk factors for tumor recurrence in liver cancer patients post-liver transplantation were analyzed.Results:The X-tile software analysis confirmed that 96.8 was the optimal cutoff value for the preoperative GLR level to predict recurrence. The grouping threshold for survival analysis using the GLR cutoff value was 96.8. The tumor recurrence rates at 1, 3, and 5 years after surgery in the low-level GLR group (90 cases) and the high-level GLR group were 19.3% vs. 44.2%, 31.8% vs. 60.0%, and 34.1% vs. 62.9% (68 cases), respectively, and the differences were statistically significant between the two groups ( P<0.05). The Kaplan-Meier survival curve analysis results showed that the overall postoperative survival rate and recurrence-free survival rate were significantly lower in the high-level GLR group than the low-level GLR group ( P<0.05). The univariate Cox analysis result showed that there were statistically significant differences in preoperative aspartate aminotransferase, alpha fetoprotein, surgery time, maximum diameter of a solitary tumor, presence or absence of microvascular invasion, presence or absence of portal vein tumor thrombus, and preoperative GLR levels between the two groups ( P<0.05). Multivariate Cox analysis results showed that preoperative alpha-fetoprotein ≥400 ng/ml, GLR≥96.8, and the maximum diameter of a solitary tumor ≥5.0 cm were independent risk factors for postoperative tumor recurrence in liver transplant recipients with liver cancer ( P<0.05). Conclusion:GLR levels have a certain predictive value for postoperative tumor recurrence in liver transplant recipients with liver cancer. Furthermore, the postoperative tumor recurrence rate is relatively high when the preoperative GLR level in liver transplant recipients with liver cancer is ≥96.8.

Objective:To investigate and analyze the clinical efficacy of salvage liver transplantation (SLT), rehepatectomy (RH), local ablation (LA), and prognostic risk factors in patients with postoperative recurrence of hepatocellular carcinoma.Methods:Clinical data of 145 patients with recurrent liver cancer in the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from January 2005 to June 2018 were retrospectively collected. SLT group, RH group, and LA group included 25, 44, and 76 cases, respectively. Follow-up and statistics were recorded on the overall survival rate, relapse-free survival rate, and complications of the three groups of patients at 1, 2, and 3 years after surgery. Univariate and multivariate COX analyses were used to analyze the prognostic risk factors in patients with recurrent HCC.Results:The overall survival rates of 1, 2, and 3 years following surgery in the SLT, RH, and LA groups were 100.0%, 84.0%, 72.0%, 95.5%, 77.3%, 65.9%, 90.8%, 76.3%, and 63.2%, respectively, when the recurrence of liver cancer met the Milan criteria. The overall survival rate did not differ statistically between SLT and RH ( P = 0.303) or between RH and LA ( P = 0.152). There were statistically significant differences in recurrence-free survival between SLT and RH or RH and LA ( P = 0.046). There was no statistically significant difference in the incidence of complications between SLT and RH or RH and LA ( P > 0.017). Age > 65 years was an independent risk factor affecting the overall survival rate in patients with recurrent HCC. Age > 65 years and recurrence time < 24 months were independent risk factors affecting the recurrence-free survival rate in patients with recurrent HCC. Conclusion:SLT is the best treatment option when the recurrence of HCC meets Milan's criteria. RH and LA are the appropriate treatment plans for recurrent HCC when the liver source is limited.

Objective:To explore the clinical risk factors of post-transplantation diabetes mellitus (PTDM) and establish a risk prediction model in kidney recipients.Methods:The clinical data and postoperative bedside measurements of blood glucose (BG) were retrospectively reviewed for 305 renal transplant recipients at First Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to August 2019.According to whether or not PTDM occurred, they were assigned into two groups of PTDM (n=34) and non-PTDM (n=271). Risk factors were screened through single/multi-factor Logistic regression and PTDM prediction model was established.Results:The incidence rate of PTDM was 11.15%(34/305). Logistic regression analysis indicated that deceased donor, age ≥40 years, female, pre-hemoglobin A1c (Pre-HbA1c) and postoperative bedside BG value ≥11.1 mmol/L were the correlated factors for the occurrence of PTDM.Among them, female ( OR=3.13, 95% CI: 1.28-7.61), Pre-HbA1c ( OR=2.05, 95% CI: 1.12-3.74) and BG ≥11.1 mmol/L at 4pm Day 2/3 post-operation ( OR=19.08, 95% CI: 4.34-83.87) were risk factors for the occurrence of PTDM, The area under the model curve was 0.86 (95% CI: 0.79-0.93) with a Jordan index of 0.65, a sensitivity of 82.8% and a specificity of 82.3%. Conclusions:Female, Pre-HbA1c and fasting BG at 4 pm Day 2/3 post-operation ≥ 11.1 mmol/L are risk factors for the occurrence of PTDM.The prediction model has a decent predictive value.It is conducive to early clinical interventions and lowering the incidence rate of PTDM.

A 24-year-old male patient was admitted to the Organ Transplant Department of the 900th Hospital of the Joint Logistic Support Force on March 13, 2000, due to repeated abdominal distension accompanied by edema of both lower limbs for more than 7 months and aggravated for 1 month. Clinical diagnosis: hepatolenticular degeneration, metabolic encephalopathy, decompensated stage of cirrhosis. Orthotopic liver transplantation was performed under general anesthesia on March 24, 2000. The postoperative recovery is smooth, and the patient has survived for more than 23 years, with normal life and work.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. At present, hepatectomy is one of the most frequent therapeutic options, whereas the high postoperative recurrence rate severely affects the long-term survival of HCC patients. Therefore, it is urgent to choose appropriate therapeutic regime to treat the recurrence of HCC to improve the long-term survival of HCC patients. Surgical treatment is an efficacious treatment for recurrent HCC, including re-hepatectomy, salvage liver transplantation and radiofrequency ablation. Currently, individualized treatment is recommended for postoperative recurrence of HCC. The selection of treatment should be conducted based on the tumor conditions after the first hepatectomy, the characteristics of recurrent tumors, baseline data of patients and recurrence time, etc., aiming to formulate appropriate treatment regimes for patients. In this article, these surgical regimes were reviewed and compared to explore appropriate surgical schemes for postoperative recurrence of HCC, aiming to provide reference for prolonging the survival of HCC patients.
