The development of immunotherapy has revolutionized the landscape of cancer treatment. Personalized neoantigen vaccines are attractive systemic immunotherapies that trigger specific T-cell responses against highly specific neoantigens, and activate and expand helper and cytotoxic T-lymphocytes to enhance anti-tumor immunity. Based on the rapid development of bioinformatics and the continuous update of sequencing technology, cancer immunotherapy with tumor neoantigens has made promising breakthroughs and progress. Researchers are exploring the value of neoantigen vaccines alone or in combination in different tumor types. We provide an overview of the complex process that is necessary to generate a personalized neoantigen vaccine, discuss the current status of clinical studies and application testing personalized neoantigen vaccines in patients with cancer and future perspectives on this novel, personalized approach to immunotherapy.
We briefly analyzed the research design and results through summarizing the latest hot spots relevant to targeted therapy in combination with immunotherapy (Abbreviated as “combination therapy” ) for hepatocellular carcinoma (HCC), aiming to provide references for clinical decision-making and future research directions. It was found that the clinical study results related to combination therapy for HCC were different by summarizing the study design and results of combination therapy for HCC in recent years, which might be closely related to the study design, drug selection, research objects selection, protocol implementation, and other factors. It is suggested that a variety of factors such as disease background should be considered when combination therapy for HCC is conducted in order to obtain a more comprehensive and objective understanding.

Methods A total of 53 patients with gastric cancer or ovarian cancer from June 2008 to April 2009 were randomly divided into two groups: 29 patients in trial group underwent intra-peritoneal chemotherapy with one-off anesthesia paracentesis kit, and 24 patients in the control group underwent intra-peritoneal chemotherapy with ordinary peritoneal paracentesis kit. The complications in two groups were compared. Results The incidence of complications in trial group was much lower than that in the control group (Plt;0.05). Conclusion One-off anesthesia paracentesis kit in intra-peritoneal chemotherapy has several advantages including simple manipulation, small injuries, and few complications, which is well accepted by the patients.
ObjectiveTo research prognostic prediction value of serum γ-glutamyltransferase-to-prealbumin ratio (GPR) for patients with hepatocellular carcinoma (HCC) after radical resection. MethodsThe clinical data of HCC patients undergoing radical resection from January 2013 to November 2021 were analyzed retrospectively. The optimal critical value of GPR was determined by receiver operating characteristic (ROC) curve. The patients were allocated into the low GPR group (GPR was the optimal critical value or less) and the high GPR group (GPR was greater than the optimal critical value). The differences of clinicopathologic characteristics were compared between the two groups. The overall survival (OS) and relapse-free survival (RFS) were analyzed by the Kaplan-Meier survival curve and compared by the log-rank test between the two groups. The risk factors affecting the OS and RFS of patients with HCC were analyzed by univariate and multivariate Cox regression, and the predictive value of GPR on the OS was evaluated by ROC curve. ResultsA total of 216 eligible HCC patients were gathered. The optimal critical value of GPR was 0.29, 93 cases were in the low GPR group and 123 cases were in the high GPR group. Compared with the low GPR group, the proportions of the patients with preoperative alanine aminotransferase >50 U/L, albumin <40 g/L, total bilirubin ≥34.2 μmol/L, tumor size >5 cm, multiple tumor lesions, stage Ⅲ of China liver cancer staging (CNLC), and major hepatectomy (liver segment resection was 3 or more) were higher in the high GPR group (P<0.05). The Kaplan-Meier survival curve showed that the OS and RFS of the low GPR group were better than those of the high GPR group (χ2=14.356, P＜0.001; χ2=7.963, P=0.005). Cox regression multivariate analysis showed that the preoperative alpha-fetoprotein (AFP) ≥400 μg/L, GPR >0.29, stage Ⅲ of CNLC, and operation time (more than 3 h) were the risk factors for OS and RFS of HCC patients (P<0.05). The area under the ROC curve of GPR alone and it in combination with risk factors (preoperative AFP and CNLC stage, respectively) and in combination with the above three indicators to predict the OS of patients with HCC were 0.636, 0.712, 0.696, and 0.737, respectively. ConclusionFrom the results of this study, GPR is associated with the postoperative survival of patients with HCC after radical resection, and GPR in combination with preoperative AFP and CNLC stage has a certain predictive value for the OS.
ObjectiveTo analyze the platelet (PLT) count, coagulation function, and portal vein thrombosis (PVT) in the patients underwent splenectomy due to different etiologies. MethodsThe patients who underwent splenectomy in the Affiliated Hospital of Southwest Medical University from January 2013 to December 2022 were collected. According to the etiology, the patients were assigned into the occupying group (splenic and pancreatic occupying lesions), hypersplenism group (portal hypertension and hypersplenism), and splenic rupture group (traumatic splenic rupture). The changes of PLT, white blood cells (WBC), red blood cells (RBC), neutrophils (Neut), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), D-dimer (DD), and PVT were observed after splenectomy. ResultsA total of 166 patients were collected, including 42 in the occupying group, 22 in the hypersplenism group, and 102 in the splenic rupture group. There were no statistically significant differences in the age and preoperative Child-Pugh score among the patients of the three groups (P>0.05). There were 12 (7.2%) patients with PVT, including 2 in the occupying group, 6 in the hypersplenismn group, and 4 in the splenic rupture group. The PVT incidence among the three groups had a statistical significant difference (Fisher exact test, P=0.003), which in the hypersplenismn group was higher than the occupying group (P=0.016) and the splenic rupture group (P=0.002), while there was no statistically significant difference between the occupying group and the splenic rupture group (P=1.000). The overall trend was that the PLT, RBC, WBC, and various coagulation function indicators such as PT, APTT, and Fib among the three groups all showed an upward trend immediately after splenectomy, but the postoperative peak time and change trends had no markedly regular among the three groups. The PLT of the patients with and without PVT changed over time during the observation period (patients without PVT: F=60.238, P<0.001; patients with PVT group: F=9.700, P=0.043), and which showed a continuous upward trend after surgery, reaching a peak on the 14th day and then beginning to decline in the patients of both 2 groups. However, there was no statistically significant intergroup effect between the 2 groups (F=0.056, P=0.816). ConclusionsThe results of this study suggest that the peak value of PLT in the hypersplenism group is lower as compared with the occupying group and the splenic rupture group, and the PVT is more likely to occur. However, no difference of the PLT level is found in the patients without and with PVT.

Conclusion Oxaliplatin combined with S1 capsule is effective on advanced gastric cancer, and the adverse effects are tolerable.
ObjectiveTo evaluate the efficacy and cost-effectiveness of thymalfasin (Tα1) as an adjuvant therapy for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after surgery.MethodsPatients with HBV-related HCC who underwent hepatectomy from February 2007 to December 2015 in West China Hospital of Sichuan University, Chengdu Military General Hospital, or the Third Affiliated Hospital of Sun Yat-sen University were retrospectively collected and divided into the Tα1 group and the observation group. Log-rank test and Kaplan-Meier curve were used to assess the overall survival, recurrence-free survival, and safety of patients. A Markov model was used to calculate the quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER) of the Tα1 group compared with the observation group. Cost data was from the hospital information system of the three hospitals. Utility scores mainly came from published data. Sensitivity analyses were applied to explore the impact of essential variables.ResultsA total of 208 patients with HCC after liver resection were enrolled, among them 48 received Tα1 treatment (the Tα1 group) and 160 were only followed up (the observation group). There was no significant difference between the two groups in the baseline characteristics. The median overall survival of the Tα1 group and the observation group was 102.0 months [95% confidence interval (CI) (74.8, 129.2) months] and 81.6 months [95%CI (65.7, 97.6) months], respectively, and the difference was statisitically significant (P=0.047); the median recurrence-free survival was 66.7 months [95%CI (17.3, 116.1) months] and 37.4 months [95%CI (28.7, 46.2) months], respectively, and the difference was statistically significant (P=0.044). There were no grade Ⅲ-Ⅳ adverse events and no treatment-related death occurred. The ICER of Tα1 group was ￥108 050.02/QALY, which was less than the willingness to pay (￥177 785.25/QALY).ConclusionsTα1, as an adjuvant therapy for HBV-related HCC patients, can improve the prognosis of the patients, and the cost is within the acceptable level in our country, so this strategy is likely to be a cost-effective option compared with the observation group.
