Abstract
Dendritic cells (DCs), the strongest antigen-presenting cells, are a focus for orchestrating the immune system in the fight against cancer. Basic scientific investigations elucidating the cellular biology of the DCs have resulted in new strategies in this fight, including cancer vaccinology, combination therapy, and adoptive cellular therapy. Although immunotherapy is currently becoming an unprecedented bench-to-bedside success, the overall response rate to the current immunotherapy in patients with gastrointestinal (GI) cancers is pretty low. Here, we have carried out a literature search of the studies of DCs in the treatment of GI cancer patients. We provide the advances in DC-based immunotherapy and highlight the clinical trials that indicate the therapeutic efficacies and toxicities related with each vaccine. Moreover, we also offer the yet-to-be-addressed questions about DC-based immunotherapy. This study focuses predominantly on the data derived from human studies to help understand the involvement of DCs in patients with GI cancers.

Abstract
Background As dendritic cells (DCs) are the major antigen-presenting cells of the immune system, understanding their role in esophageal cancer is essential for the development of preventative and treatment strategies. This study investigated the expression level and clinical value of tumor infiltrating dendritic cells (TIDCs) in tumor tissues of patients with esophageal cancer. Methods From January 2019 to January 2021, 184 patients with esophageal cancer treated were prospectively enrolled as the observation group and 184 patients with benign esophageal tumors were selected as the control group. Tumor tissue samples were obtained and the expression level and phenotypes of the TIDCs were analyzed. The correlation between TIDC expression and clinical characteristics of patients with esophageal cancer was investigated. Results The density of the TIDCs in the observation group was lower than that in the control group (8.76±2.25 vs. 9.97±2.19; P=0.000). Furthermore, the percentage of major histocompatibility complex-II (MHC-II) positive DCs and the percentage of CD54 positive DCs were relatively lower in the observation group compared to the control group (6.60%±2.12% vs. 9.34%±2.41%; P=0.000 and 7.41%±2.36% vs. 9.98%±2.47%; P=0.000, respectively). Esophageal cancer patients with lymph node metastasis had lower TIDC density, lower percentage of MHC-II positive DCs, and lower percentage of CD54 positive DCs compared to patients without node metastasis (P<0.05). Patients with stage III esophageal cancer also showed significantly lower TIDC density, lower percentage of MHC-II positive DCs, and lower percentage of CD54 positive DCs compared to patients with stage I/II esophageal cancer (P<0.05). Esophageal cancer patients with tumor diameter ≥4 cm presented with decreased TIDC density, decreased percentage of MHC-II positive DCs, and decreased percentage of CD54 positive DCs compared to patients with tumor diameter <4 cm (P<0.05). In addition, the density of TIDCs, the percentage of MHC-II positive DCs, and the percentage of CD54 positive DCs were significantly negatively correlated with the percentage of CD4+ T-lymphocytes and positively correlated with the percentage of CD8+ T-lymphocytes (P<0.05). Conclusions Patients with esophageal cancer had low expression and function of TIDCs, and this was related to the imbalance of T-lymphocyte subsets, lymph node metastasis, TNM stage, and lesion size.

Abstract
Recently, cytokine-induced killer (CIK) cells have been shown to possess effective cytotoxic activity against some tumor cells both in vitro and in clinical research. Furthermore, dendritic cell-activated CIK (DC-CIK) cells display significantly increased antitumor activity compared to unstimulated CIK cells. Study findings indicate DC cells can secrete chemokine C-C motif ligand 17 (CCL17) and chemokine C-C motif ligand 22 (CCL22) with a common receptor molecule, C-C chemokine receptor type-4(CCR4). CCL17 and CCL22 levels were measured by ELISA from CIK cell culture supernatants and the expression of CCR4 on CIK and DC-CIK cells was analyzed by flow cytometry. Through Migration and Killing assays, further analyzed the effects of the altered expression levels of CCR4 on the chemotactic ability and the tumor-killing efficiency of CIK cells. We found markedly increased CCL17 and CCL22 in supernatants of DC-CIK co-cultures. Similarly, the expression of CCR4 was also increased on CIK cells in these co-cultures. Further, the stimulation of CCL17 and CCL22 increased expression of the CCR4 and enhanced the migratory capacity and antitumor efficacy of CIK cells. Simultaneously, similar effects had achieved by transfecting the CCR4 gene into CIK cells. DC cells may promote the expression of CCR4 on CIK cells by secreting CCL17 and CCL22, thereby promoting infiltration of DC-CIK cells into the tumor microenvironment, and exerting stronger antitumor activity than CIK cells.

Abstract
BACKGROUND Esophageal carcinoma (EC) is one of the worst malignant digestive neoplasms with a strong tendency of invasion and metastasis. Despite the improvement of diagnostic and therapeutic methods in the past decades, the prognosis of EC remains unsatisfactory. Xiaoaiping injection (XAPI), a famous traditional Chinese herbal medicine, has been widely applied as a promising adjunctive drug for EC. However, the exact effects and safety of XAPI have yet to be systematically investigated. We aimed to summarize the efficacy and safety of XAPI for the treatment of advanced EC through the meta-analysis, in order to provide scientific reference for the design of future clinical trials. METHODS Relevant randomized controlled trials (RCTs) were searched from Cochrane Library, PubMed, Google Scholar, Web of Science, Excerpt Medica Database, Medline, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, China Scientific Journal Database and Wanfang Database. Papers in English or Chinese published from January 2000 to May 2020 will be included without any restrictions.Study selection and data extraction will be performed independently by 2 investigators. The clinical outcomes including overall response rate, complete response rate, overall survival, Disease-free survival, quality of life, immune function and adverse events, were systematically evaluated. Review Manager 5.3 and Stata 14.0 were used for data analysis, and the quality of the studies was also evaluated. RESULTS The results of this study will be published in a peer-reviewed journal, and provide more evidence-based guidance in clinical practice. CONCLUSION Our study will draw an objective conclusion of the effects of XAPI combined with conventional treatment for advanced EC and provide a helpful evidence for clinicians to formulate the best postoperative adjuvant treatment strategy for EC patients.

Abstract
Immunotherapy represents the newest pillar in cancer care. Although there are increasing data showing the efficacy of immunotherapy there is a spectrum of response across unselected populations of cancer patients. In fact, response rates can be poor even among patients with immunogenic tumors for reasons that remain poorly understood. A promising clinical strategy to improve outcomes, which is supported by an abundance of preclinical data, is combining immunotherapy with radiation therapy. Here we review the existing evidence and future directions for combining immunotherapy and radiation therapy for patients with gastrointestinal cancers.

Abstract
Objective The aim of this study was to systematically evaluate the efficacy and safety of the combination of dendritic cells and cytokine-induced killer cells (DC–CIK) adjuvant immunotherapy and chemotherapy in the treatment of multiple myeloma (MM). Methods Clinical trials were gathered by searching Web of Science, PubMed, Embase, Cochrane Library, Wanfang, and CNKI database. Outcome measurements including therapeutic efficacy, prognosis, immune function, and adverse events were extracted and evaluated. Results A total of 12 trials including 594 MM patients were involved in this study for statistical analysis. Results indicated that compared to chemotherapy alone, the combination of DC–CIK immunotherapy with chemotherapy significantly improved patients’ overall response rate (ORR, odds ratio [OR] =2.77, 95% confidence interval [CI] =1.88–4.10, P<0.00001), disease control rate (DCR, OR =2.90, CI =1.72–4.90, P<0.0001), and life quality (P<0.00001). The combined therapy showed advantages over chemotherapy alone in prognostic indicators including percentage of tumor cells (P=0.04), serum levels of β2-microglobin (P<0.0001), M protein (P<0.00001), and creatinine (P<0.0001), and 24 h urine light chains (P<0.00001). After combined treatment, CD4+ lymphocyte subsets’ percentages, CD4+/CD8+ ratio, and cytokines levels of AgNOR, IFN-γ, IL-2, and IL-12 were significantly increased (P<0.05), whereas CD8+ and CD4+CD25+ percentages and IL-4, IL-6, IL-10, and TGF-β levels were obviously decreased (P<0.01), indicating a recovered immune condition. Conclusion Adjuvant DC–CIK immunotherapy enhances the efficacy of chemotherapy for MM and improves prognosis probably by reconstructing immune function.

Abstract
PURPOSE This study aimed to systematically evaluate the efficacy and safety of dendritic cells-cytokine-induced killer (DC-CIK) cells immunotherapy in treating pancreatic cancer (PC) patients. METHODS Data were collected from published articles of clinical trials. Databases including Web of Science, EMBASE, PubMed, Cochrane Library, Wanfang, and CNKI were searched. The main outcome measures in this research included the overall response rate (ORR), disease control rate (DCR), overall survival (OS), patients' quality of life (QoL), immune function, and adverse events. Comparative analysis was conducted between DC-CIK immunotherapy and chemotherapy (combined therapy) and chemotherapy alone. RESULTS This analysis covered 14 trials with 1,088 PC patients involved. The combined therapy showed advantages over chemotherapy alone in ORR (odds ratio [OR] =1.69, 95% confidence interval [CI] =1.20-2.38, P=0.003), DCR (OR =2.33, 95% CI =1.63-3.33, P<0.00001), OS (1-year OS, OR =3.61, 95% CI =2.41-5.40, P<0.00001; 3-year OS, OR =2.65, 95% CI =1.56-4.50, P=0.0003) and patients' QoL (P<0.01) with statistical significance. After immunotherapy, lymphocyte subsets' percentages of CD3+ (P<0.00001), CD4+ (P=0.01), CD3+CD56+ (P<0.00001), and cytokine levels of IFN-γ (P<0.00001) were significantly increased, and the percentages of CD4+CD25+CD127low (P<0.00001) and levels of IL-4 (P<0.0001) were significantly decreased, whereas analysis on CD8+ (P=0.59) and CD4+/CD8+ ratio (P=0.64) did not show a significant difference. CONCLUSION The combination of DC-CIK immunotherapy and chemotherapy is effective for PC treatment, indicated by prolonging the PC patients' survival time, which benefit from reconstructed immune function of patients.
