The effect of long-term traditional Chinese medicine treatment on disease-free survival of postoperative stage I-III lung cancer patients:a retrospective cohort study

Objective:Traditional Chinese medicine(TCM)has been extensively used as one of popular alternative therapies for several cancers.However,it remains unclear whether TCM treatment is associated with longer survival in lung cancer patients.In this study,we explored the effect of long-term TCM treatment on patients with different stages of lung cancer.Methods:All information of lung cancer patients with stage I-III disease from January 2007 to September 2015 was collected for this retrospective cohort study.Those who were treated with TCM after surgery were divided into TCM group and the others were into the non-TCM group(control group).All patients were regularly followed up by clinic appointment or phone,and all survival data were collected from databases after the last follow-up in October 2017.Results:A total of 575 patients were included in this study,with 299 patients in the TCM group and 276 in the control group.For all patients,5-year disease-free survival(DFS)was 62.2% in TCM group and 42.1% in the control group,and 6-year DFSs were 51.8% and 35.4%,respectively(HR=0.51,95% CI:0.40 to 0.66,log-rank P≤0.001).For patients with stage I,5-year DFSs were 83.7%(TCM group)and 57.5%(control group)and 6-year DFSs were 73.7% and 51.9%,respectively(HR=0.30,95% CI:0.18 to 0.50,log-rank P≤0.001).For patients with stage II in the TCM group and the control group,5-year DFSs were 59.4% and 17.6% and 6-year DFSs were 44.7% and 17.6%,respectively(HR=0.31,95% CI:0.19 to 0.52,log-rank P≤0.001),and for patients with stage III,5-year and 6-year DFSs in the TCM group were 18.7% and 12.5% compared with 28.4% and 20.3% in the control group(HR=1.06,95% CI:0.72 to 1.56,log-rank P=0.76).Conclusions:This study demonstrated that long-term TCM treatment as an adjuvant therapy is able to improve the DFS of postoperative stage I-III lung cancer patients,especially in patients with stage I and II disease.However,these observational findings need being validated by large sample randomized controlled trials.

Prognostic factors for disease-free survival in postoperative patients with hepatocellular carcinoma and construction of a nomogram model

BACKGROUND Hepatocellular carcinoma(HCC)is the most common type of liver cancer and has a high risk of invasion and metastasis along with a poor prognosis.AIM To investigate the independent predictive markers for disease-free survival(DFS)in patients with HCC and establish a trustworthy nomogram.METHODS In this study,445 patients who were hospitalized in The First Affiliated Hospital of Anhui Medical College between December 2009 and December 2014 were retrospectively examined.The survival curve was plotted using the Kaplan–Meier method and survival was determined using the log-rank test.To identify the prognostic variables,multivariate Cox regression analyses were carried out.To predict the DFS in patients with HCC,a nomogram was created.C-indices and receiver operator characteristic curves were used to evaluate the nomogram’s performance.Decision curve analysis(DCA)was used to evaluate the clinical application value of the nomogram.RESULTS Longer DFS was observed in patients with the following characteristics:elderly,I–II stage,and no history of hepatitis B.The calibration curve showed that this nomogram was reliable and had a higher area under the curve value than the tumor node metastasis(TNM)stage.Moreover,the DCA curve revealed that the nomogram had good clinical applicability in predicting 3-and 5-year DFS in HCC patients after surgery.CONCLUSION Age,TNM stage,and history of hepatitis B infection were independent factors for DFS in HCC patients,and a novel nomogram for DFS of HCC patients was created and validated.

Deep learning-based multi-modal data integration enhancing breast cancer disease-free survival prediction

Background:The prognosis of breast cancer is often unfavorable,emphasizing the need for early metastasis risk detection and accurate treatment predictions.This study aimed to develop a novel multi-modal deep learning model using preoperative data to predict disease-free survival(DFS).Methods:We retrospectively collected pathology imaging,molecular and clinical data from The Cancer Genome Atlas and one independent institution in China.We developed a novel Deep Learning Clinical Medicine Based Pathological Gene Multi-modal(DeepClinMed-PGM)model for DFS prediction,integrating clinicopathological data with molecular insights.The patients included the training cohort(n=741),internal validation cohort(n=184),and external testing cohort(n=95).Result:Integrating multi-modal data into the DeepClinMed-PGM model significantly improved area under the receiver operating characteristic curve(AUC)values.In the training cohort,AUC values for 1-,3-,and 5-year DFS predictions increased to 0.979,0.957,and 0.871,while in the external testing cohort,the values reached 0.851,0.878,and 0.938 for 1-,2-,and 3-year DFS predictions,respectively.The DeepClinMed-PGM's robust discriminative capabilities were consistently evident across various cohorts,including the training cohort[hazard ratio(HR)0.027,95%confidence interval(CI)0.0016-0.046,P<0.0001],the internal validation cohort(HR 0.117,95%CI 0.041-0.334,P<0.0001),and the external cohort(HR 0.061,95%CI 0.017-0.218,P<0.0001).Additionally,the DeepClinMed-PGM model demonstrated C-index values of 0.925,0.823,and 0.864 within the three cohorts,respectively.Conclusion:This study introduces an approach to breast cancer prognosis,integrating imaging and molecular and clinical data for enhanced predictive accuracy,offering promise for personalized treatment strategies.

Preoperative albumin-bilirubin score predicts short-term outcomes and long-term prognosis in colorectal cancer patients undergoing radical surgery

BACKGROUND The albumin-bilirubin(ALBI)score is a serum biochemical indicator of liver function and has been proven to have prognostic value in a variety of cancers.In colorectal cancer(CRC),a high ALBI score tends to be associated with poorer survival.AIM To investigate the correlation between the preoperative ALBI score and outcomes in CRC patients who underwent radical surgery.METHODS Patients who underwent radical CRC surgery between January 2011 and January 2020 at a single clinical center were included.The ALBI score was calculated by the formula(log10 bilirubin×0.66)+(albumin×-0.085),and the cutoff value for grouping patients was-2.8.The short-term outcomes,overall survival(OS),and disease-free survival(DFS)were calculated.RESULTS A total of 4025 CRC patients who underwent radical surgery were enrolled in this study,and there were 1908 patients in the low ALBI group and 2117 patients in the high ALBI group.Cox regression analysis revealed that age,tumor size,tumor stage,ALBI score,and overall complications were independent risk factors for OS;age,tumor stage,ALBI score,and overall complications were identified as independent risk factors for DFS.CONCLUSION A high preoperative ALBI score is correlated with adverse short-term outcomes,and the ALBI score is an independent risk factor for OS and DFS in patients with CRC undergoing radical surgery.

Predictive value of preoperative routine examination for the prognosis of patients with pT2N0M0 or pT3N0M0 colorectal cancer

BACKGROUND In recent years,the incidence of colorectal cancer(CRC)has been increasing.With the popularization of endoscopic technology,a number of early CRC has been diagnosed.However,despite current treatment methods,some patients with early CRC still experience postoperative recurrence and metastasis.AIM To search for indicators associated with early CRC recurrence and metastasis to identify high-risk populations.METHODS A total of 513 patients with pT2N0M0 or pT3N0M0 CRC were retrospectively enrolled in this study.Results of blood routine test,liver and kidney function tests and tumor markers were collected before surgery.Patients were followed up through disease-specific database and telephone interviews.Tumor recurrence,metastasis or death were used as the end point of study to find the risk factors and predictive value related to early CRC recurrence and metastasis.RESULTS We comprehensively compared the predictive value of preoperative blood routine,blood biochemistry and tumor markers for disease-free survival(DFS)and overall survival(OS)of CRC.Cox multivariate analysis demonstrated that low platelet count was significantly associated with poor DFS[hazard ratio(HR)=0.995,95% confidence interval(CI):0.991-0.999,P=0.015],while serum carcinoembryonic antigen(CEA)level(HR=1.008,95%CI:1.001-1.016,P=0.027)and serum total cholesterol level(HR=1.538,95%CI:1.026-2.305,P=0.037)were independent risk factors for OS.The cutoff value of serum CEA level for predicting OS was 2.74 ng/mL.Although the OS of CRC patients with serum CEA higher than the cutoff value was worse than those with lower CEA level,the difference between the two groups was not statistically significant(P=0.075).CONCLUSION For patients with T2N0M0 or T3N0M0 CRC,preoperative platelet count was a protective factor for DFS,while serum CEA level was an independent risk factor for OS.Given that these measures are easier to detect and more acceptable to patients,they may have broader applications.
