Project description:To study the value of neoadjuvant chemotherapy (NAC) for advanced gastric cancer by performing a meta-analysis of the published studies.All published controlled trials of NAC for advanced gastric cancer vs no therapy before surgery were searched. Studies that included patients with metastases at enrollment were excluded. Databases included Cochrane Library of Clinical Comparative Trials, MEDLINE, Embase, and American Society of Clinical Oncology meeting abstracts from 1978 to 2010. The censor date was up to April 2010. Primary outcome was the odds ratio (OR) for improving overall survival rate of patients with advanced gastric cancer. Secondary outcome was the OR for down-staging tumor and increasing R0 resection in patients with advanced gastric cancer. Safety analyses were also performed. All calculations and statistical tests were performed using RevMan 5.0 software.A total of 2271 patients with advanced gastric cancer enrolled in 14 trials were divided into NAC group (n = 1054) and control group (n = 1217). The patients were followed up for a median time of 54 mo. NAC significantly improved the survival rate [OR = 1.27, 95% confidence interval (CI): 1.04-1.55], tumor stage (OR = 1.71, 95% CI: 1.26-2.33) and R0 resection rate (OR = 1.51, 95% CI: 1.19-1.91) of patients with advanced gastric cancer. No obvious safety concerns were raised in these trials.NAC can improve tumor stage and survival rate of patients with advanced gastric cancer with a rather good safety.

Project description:BackgroundPrior to the approval of sorafenib, hepatic arterial infusion chemotherapy (HAIC) was offered to patients with advanced hepatocellular carcinoma (HCC) in East Asia, particularly Japan. According to the Japanese guidelines, HAIC is recommended as one of the treatment options in patients without extrahepatic metastasis (EHM).MethodsThe present cohort study compared the use of HAIC and sorafenib on outcomes of patients with advanced HCC. Consecutive patients with advanced HCC who received HAIC or sorafenib as a first-line systemic therapy were enrolled from 10 Japanese institutions. The primary outcomes were overall survival (OS) in patients with macrovascular invasion (MVI), but without EHM, and OS in patients without both MVI and EHM.ResultsBetween 2009 and 2016, 2,006 patients were enrolled (541 HAIC patients, 1,465 sorafenib patients). After propensity score matching, the OS of patients with MVI but without EHM was significantly longer in the HAIC group compared with the sorafenib group (10.1 vs. 9.1 months for the HAIC and sorafenib groups, respectively; n = 170 for each group; hazard ratio [HR] 0.668; 95% confidence interval [95% CI] 0.475-0.935; p = 0.018). There was no significant difference in OS between patients without both MVI and EHM (12.2 vs. 15.4 months for the HAIC and sorafenib groups, respectively; n = 76 in each cohort after propensity score matching; HR 1.227; 95% CI 0.699-2.155; p = 0.475).ConclusionHAIC is a potential front-line treatment choice in a subpopulation of patients with advanced HCC with MVI but without EHM.

Project description:BackgroundThe prognostic values of preoperative tumor markers (TMs) remain elusive in patients with locally advanced gastric cancer (LAGC) after neoadjuvant chemotherapy treatment (NACT). This study aimed to assess and establish a novel scoring system incorporating carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 72-4 (CA72-4) to enhance prognostic accuracy for progression-free survival (PFS) and pathological response (pCR).MethodsPatients' data were retrospectively analyzed from December 2006 to December 2017 in our center. The cutoff value of TMs was determined using the time-dependent receiver operating test characteristics method. These three TMs were allocated 1 point each for the post neoadjuvant chemotherapy combination of tumor markers (post-NACT CTM) scores. The training group comprised 533 patients, responsible for full analysis, and the validation group comprised 137 patients based on the selection protocol.ResultsOf 533 enrolled patients, 138, 233, 117, and 45 patients scored 0, 1, 2, 3 respectively. The 3-year PFS rate Multivariate analysis revealed that post-NACT CTM score was an independent predictor of PFS (0 vs. 1, HR: 1.34, 95% CI: 0.92-1.96, P = 0.128; 0 vs. 2, HR: 2.03, 95% CI: 1.35-3.05, P = 0.001; 0 vs. 3, HR: 2.98, 95% CI: 1.83-4.86, P < 0.001). The time-dependent area under curve (AUC) revealed a consistent highest level for post-NACT CTM than other three single TMs. Lower post-NACT CTM score significantly correlated with higher pCR rate based on multivariate logistic regression (2/3 vs. 1, OR: 2.77, 95% CI: 0.90-8.53, P = 0.077; 2/3 vs. 0, OR: 4.33, 95% CI: 1.38-13.61, P = 0.012). A nomogram was formed with both internal and external validation.ConclusionsThe post-NACT CTM score system served as a strong independent predictor for PFS and pCR in LAGC patients who received NACT. Further population-based studies are required to confirm our results.

Project description:Purpose: Immunotherapy combined with chemotherapy have synergistic effects in multiple malignancies. We aimed to compare the efficacy and safety of toripalimab plus hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, fluorouracil, and leucovorin versus lenvatinib in advanced hepatocellular carcinoma (HCC). Materials and Methods: We conducted this retrospective study at 3 hospitals in China and eligible patients were 18 years or older and had a primary diagnosis of unresectable HCC with macroscopic vascular invasion and/or extrahepatic spread. These patients were treated with toripalimab plus HAIC or lenvatinib monotherapy. The primary endpoint was progression-free survival (PFS) and the secondary endpoints were overall survival (OS), disease control rate per response evaluation criteria in solid tumors (RECIST) 1.1, and objective response rate (ORR) per RECIST 1.1. The results were compared by Student's test or the chi-square test, and the survival curves were calculated by the Kaplan-Meier method, and propensity-score matching (PSM) was used to reduce bias. Results: A total of 118 patients were recruited for this study: 53 in the TorHAIC group and 65 in the lenvatinib group. We found that the TorHAIC group showed a longer PFS (9.3 [95% CI, 7.81-10.8] vs 4.8 months [95% CI, 3.31-6.29]; hazard ratio [HR] = 0.57, 95% CI, 0.38-0.85; p = .006), a longer OS (17.13 [95% CI, 13.99-20.27] vs 10.1 months [95% CI, 8.14-12.06]; HR = 0.5, 95% CI, 0.31 - 0.81; p = .005), a higher disease control rate (86.8% vs 69.2%, p = .002) and a higher ORR (47.2% vs 9.2%, p < .001) by RECIST criteria than the lenvatinib group. Both toripalimab plus HAIC and lenvatinib had acceptable safety profiles. No treatment-related deaths occurred in this study. In the propensity score-matched cohorts (47 pairs), the outcomes in the TorHAIC group were also better than those in the lenvatinib group (p < .05). Conclusion: Toripalimab plus HAIC was tolerable and effective in advanced HCC and the result needs to be confirmed in the phase III trial.

Project description:BackgroundThe relationship between time to surgery (TTS) and survival benefit is not sufficiently demonstrated by previous studies in locally advanced gastric cancer (LAGC). This study aims to assess the impact of TTS after neoadjuvant chemotherapy (NACT) on long-term and short-term outcomes in LAGC patients.MethodsData were collected from patients with LAGC who underwent NACT between January 2007 and January 2018 at our institution. Outcomes assessed were long-term survival, pathologic complete response (pCR) rate, and postoperative complications.ResultsThis cohort of 426 patients was divided into five groups by weeks of TTS. Under cox regression, compared to other groups, the 22-28 days and 29-35 days groups revealed a better OS (≤21 vs. 22-28 days: HR 1.54, 95% CI = 0.81-2.93, P = 0.185; 36-42 vs. 22-28 days: HR 2.20, 95% CI = 1.28-3.79, P = 0.004; 43-84 vs. 22-28 days: HR 1.83, 95% CI = 1.09-3.06, P = 0.022) and PFS (≤21 vs. 22-28 days: HR 1.54, 95% CI = 0.81-2.93, P = 0.256; 36-42 vs. 22-28 days: HR 2.20, 95% CI = 1.28-3.79, P = 0.111; 43-84 vs. 22-28 days: HR 1.83, 95% CI = 1.09-3.06, P = 0.047). Further analysis revealed a better prognosis in patients with TTS within 22-35 days (OS: HR 1.78 95% CI = 1.25-2.54, P = 0.001; PFS: HR 1.49, 95% CI = 1.07-2.08, P = 0.017). Postoperative stay was significantly higher in the ≤21 days group, while other parameters revealed no statistical significance (P > 0.05). Restricted cubic spline depicted the nonlinear relationship between TTS and OS/PFS.ConclusionPatients who received surgery within 3-5 weeks experienced the maximal survival benefit without an increase in postoperative complications or lowering the rate of pCR. Further investigations are warranted.

Project description:BackgroundSensitivity to neoadjuvant chemotherapy in locally advanced gastric cancer patients varies; however, an effective predictive marker is currently lacking. We aimed to propose and validate a practical treatment efficacy prediction method based on contrast-enhanced computed tomography (CECT) radiomics.MethodData of l24 locally advanced gastric carcinoma patients who underwent neoadjuvant chemotherapy were acquired retrospectively between December 2012 and August 2020 from three different cancer centers. In total, 1216 radiomics features were initially extracted from each lesion's pretreatment portal venous phase computed tomography image. Subsequently, a radiomics predictive model was constructed using machine learning software. Clinicopathological data and radiological parameters of the enrolled patients were collected and analyzed retrospectively. Univariate and multivariate logistic regression analyses were performed to screen for independent predictive indices. Finally, we developed an integrated model combining clinicopathological predictive parameters and radiomics features.ResultIn the training set, 10 (14.9%) patients achieved a good response (GR) after preoperative neoadjuvant chemotherapy (n = 77), whereas in the testing set, seven (17.5%) patients achieved a GR (n = 47). The radiomics predictive model showed competitive prediction efficacy in both the training and independent external validation sets. The areas under the curve (AUC) values were 0.827 (95% confidence interval [CI]: 0.609-1.000) and 0.854 (95% CI: 0.610-1.000), respectively. Similarly, when only the single hospital data were included as an independent external validation set (testing set 2), AUC values of the models were 0.827 (95% CI: 0.650-0.952) and 0.889 (95% CI: 0.663-1.000) in the training set and testing set 2, respectively.ConclusionOur study is the first to discover that CECT radiomics could provide powerful and consistent predictions of therapeutic sensitivity to neoadjuvant chemotherapy among gastric cancer patients across different hospitals.

Project description:BACKGROUND:Hepatic arterial infusion chemotherapy (HAIC) is frequently used to treat advanced hepatocellular carcinoma (HCC) in Asian countries. However, there is a lack of evidence supporting the use of HAIC. SUMMARY:Many studies report high response rates in patients with advanced HCC receiving HAIC, and clinical responses translate to survival benefits. Therefore, prediction of an antitumor response is important in selecting appropriate treatments. There are no proven post-sorafenib therapeutic measures or procedures for HCC patients with poor liver function, and HAIC is one of the few options for patients in these situations. Despite studies showing its effectiveness, the use of HAIC for treatment of advanced HCC is unclear because convincing data from large-scale randomized clinical trials are lacking. For HAIC to become a standard treatment for HCC, such trials must establish its efficacy compared with other HCC therapies; prediction of antitumor response in HAIC may aid trial design, and a multi-center, open-labelled, randomized clinical trial of HAIC in advanced HCC is currently in progress. Optimization of HCC treatment protocols and regimens is also required. KEY MESSAGE:We think that both HAIC and sorafenib are effective treatments for advanced HCC, and this review presents evidence supporting this contention.

Project description:Background & aimsHepatic arterial infusion chemotherapy (HAIC) is an option for treating advanced hepatocellular carcinoma (HCC). Because of the poor prognosis in HAIC non-responders, it is important to identify patients who may benefit from continuous HAIC treatment; however, there are currently no therapeutic assessment scores for this identification. Therefore, we aimed to establish a new therapeutic assessment score for such patients.MethodsWe retrospectively analyzed 90 advanced HCC patients with elevated baseline alpha-fetoprotein (AFP) and/or des-gamma-carboxy prothrombin (DCP) levels and analyzed various parameters for their possible use as predictors of response and survival. AFP and DCP responses were assessed after half a course of HAIC (2 weeks); a positive-response was defined as a reduction of ? 20% from baseline.ResultsMultivariate analysis identified DCP response (odds ratio 16.03, p < 0.001) as an independent predictor of treatment response. In multivariate analysis, Child-Pugh class A (hazard ratio [HR] 1.99, p = 0.018), AFP response (HR 2.17, p = 0.007), and DCP response (HR 1.90, p = 0.030) were independent prognostic predictors. We developed an Assessment for Continuous Treatment with HAIC (ACTH) score, including the above 3 factors, which ranged from 0 to 3. Patients stratified into two groups according to this score showed significantly different prognoses (? 1 vs. ? 2 points: median survival time, 15.1 vs. 8.7 months; p = 0.003).ConclusionsThe ACTH score may be useful in the therapeutic assessment of HCC patients receiving HAIC.

Project description:BackgroundHepatic arterial infusion chemotherapy delivers the drug directly to the liver. We aim to explore the benefits and tolerability of Hepatic arterial infusion chemotherapy plus regorafenib in advanced colorectal liver metastasis refractory to standard systemic chemotherapy.MethodsThis study analyzed 47 patients treated with hepatic arterial infusion chemotherapy plus regorafenib after standard systemic oxaliplatin and/or irinotecan in combination with bevacizumab or cetuximab between Jan 2017 and Jun 2020. Regorafenib was given for only 3 weeks in a 4-week cycle.ResultsAmong 47 patients, 32 (68%) were males. The median age was 61 (29-75). With a median follow-up of 22.2 months (3.7-50.7 months). Before Hepatic arterial infusion chemotherapy administration in combination with regorafenib, 34 (72.3%) patients previously received ≥ 2 prior lines of systemic therapy and 37 (78.7%)patients previously received targeted biological treatment (anti-VEGF or anti-EGFR, or both). The initial doses of regorafenib were 40 mg/d (n = 1, 2.13%), 80 mg/d (n = 11, 23.43%), 120 mg/d (n = 2, 4.26%), and 160 mg/d (n = 23, 48.94%), while for 24.6% (n = 14) dose was unknown. Median Overall Survival was 22.2 months. Median Progression-Free Survival was 10.8 (95% CI: 9.0-13.7) months. Common Adverse Events were hand-foot skin reaction (12.77%), fatigue (6.38%), vomiting (6.38%), and decreased appetite (6.38%). Only 2 patients discontinued regorafenib due to Adverse Events.ConclusionsRegorafenib combined with Hepatic arterial infusion was effective and tolerable in patients with liver predominant metastasis of colorectal cancer. Hence, this therapy can be considered as an alternative for second- or subsequent lines of therapy in patients refractory to standard systemic chemotherapy.

Project description:BackgroundSerum tumor markers including AFU, AFP, CEA, CA199, CA125 and CA724, are of great importance in the diagnosis, prognostic prediction and recurrence monitoring of gastrointestinal malignancies. However, their significance in gastric cancer (GC) patients with neoadjuvant therapy (NCT) is still uncertain. The aim of this study was to evaluate the predictive value of these six tumor markers in locally advanced GC patients who underwent NCT and curative surgery.MethodsIn total, 290 locally advanced GC patients who underwent NCT and D2 radical gastrectomy were retrospectively analyzed. Data on their tumor markers before (pre-) and after (post-) NCT and pathological characteristics were extracted from the database of our hospital. The optimal cutoff values of the six tumor markers were calculated by the ROC curve and Youden index. Their predictive significance was analyzed and survival curves for overall survival (OS) were obtained by the Kaplan-Meier method. Associations between categorical variables were explored by the chi-square test or Fisher's exact test. Multivariate analyses were performed by the Cox regression model.ResultsPre- and post-CA199, -CA125 and -CA724 could predict overall survival (all P?<?0.05), but only the change (diff-) of CA199 was related to prognosis (P?=?0.05). In the multivariable analysis, pre- (P?=?0.014) and post-CA724 (P?=?0.036) remained significant, though diff-CA724 was not an independent prognostic factor (P?=?0.581). In addition, pre- and post-CA199, -CA125 and -CA724 were associated with lymph node metastasis (N- vs N+) and pathological stage (I-II vs III) (all P?<?0.05). Moreover, post-CA724 was related to the vascular or lymphatic invasion (P?=?0.019), while pre-CA724 was not (P?=?0.082). However, AFU, AFP and CEA showed no association with survival (P?>?0.05).ConclusionsCA724 is an independent factor for prognosis and could be used to predict ypN and ypTNM stage in locally advanced GC patients undergoing NCT and curative resection.
