XELOX (capecitabine plus oxaliplatin) plus bevacizumab (anti-VEGF-A antibody) with or without adoptive cell immunotherapy in the treatment of patients with previously untreated metastatic colorectal cancer: a multicenter, open-label, randomized, controlled, phase 3 trial.

Fluoropyrimidine-based combination chemotherapy plus targeted therapy is the standard initial treatment for unresectable metastatic colorectal cancer (mCRC), but the prognosis remains poor. This phase 3 trial (ClinicalTrials.gov: NCT03950154) assessed the efficacy and adverse events (AEs) of the combination of PD-1 blockade-activated DC-CIK (PD1-T) cells with XELOX plus bevacizumab as a first-line therapy in patients with mCRC.

GPC5 suppresses lung cancer progression and metastasis via intracellular CTDSP1/AhR/ARNT signaling axis and extracellular exosome secretion.

Lung cancer is the leading cause of cancer-related death worldwide. Glypican-5 (GPC5) is a member of heparan sulfate proteoglycans, and its biological importance in initiation and progression of lung cancer remains controversial. In the present study, we revealed that GPC5 transcriptionally enhanced the expression of CTDSP1 (miR-26b host gene) via AhR-ARNT pathway, and such up-regulation of CTDSP1 intracellularly contributed to the inhibited proliferation of lung cancer cells.

Clinical significance of IFIT2 expression in human renal cancer tissues.

Background: Interferon (IFN)-induced protein with tetratricopeptide repeats 2 (IFIT2) is an important member of the IFN-stimulated gene (ISG) family. It has been demonstrated that IFIT2 is important in the physiopathological processes of antiviral and antitumor activities. We previously demonstrated that IFIT2 was highly expressed in paracarcinoma tissues compared with gastric cancer tissues, and its expression level was positively correlated with a superior postoperative prognosis of the patients.

Aim: Systemic inflammatory response is closely related to tumor progression. We retrospectively investigated relationships between systemic inflammatory scores, C-reactive protein/albumin (CRP/Alb) ratio (CAR) and clinical characteristics in advanced non-small-cell lung cancer (NSCLC) in 436 patients to find better clinical predictors of NSCLC prognosis.

Methods: Blood specimens were collected 1 week before treatment to test for systemic inflammatory scores and albumin.

Prognostic value of interim (18)F-FDG-PET in diffuse large B cell lymphoma treated with rituximab-based immune-chemotherapy: a systematic review and meta-analysis.

The prognostic value of an interim fluorine-18-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) for diffuse large B-cell lymphoma (DLBCL) has been assessed by different groups. However, studies have suggested that the use of rituximab could limit the predictive value of interim (18)F-FDG PET for DLBCL. To clarify the prognostic value of interim (18)F-FDG PET in DLBCL patients treated with rituximab based immunochemotherapy, we searched for relevant studies in PubMed, the Cochrane Library and EMBASE.

The status of perineural invasion predicts the outcomes of postoperative radiotherapy in locally advanced esophageal squamous cell carcinoma.

Background: Prognosis of locally advanced esophageal squamous cell carcinoma (ESCC) remains dismal even after curative resection and adjuvant radiotherapy. New biomarkers for predicting prognosis and treatment outcomes are needed for improved treatment stratification of patients with locally advanced ESCC. The prognostic and treatment predictive significance of perineural invasion (PNI) in the locally advanced ESCC remains unclear.

Proposed Modification of Nodal Staging as an Alternative to the Seventh Edition of the American Joint Committee on Cancer Tumor-Node-Metastasis Staging System Improves the Prognostic Prediction in the Resected Esophageal Squamous-Cell Carcinoma.

Introduction: The 7th American Joint Committee on Cancer (AJCC) tumor-node-metastasis staging system for esophageal cancer defined N classification based on the number of metastatic lymph nodes (LNs). However, this classification might neglect the extent of LNs metastasis. This study aimed to revise N classification based on the extent of LNs metastasis and propose a modification to the current AJCC staging system for better representing the prognostic characteristics of Chinese esophageal squamous-cell carcinoma (ESCC).

Cytokine-induced killer cells co-cultured with dendritic cells loaded with the protein lysate produced by radiofrequency ablation induce a specific antitumor response.

Radiofrequency ablation (RFA) causes coagulative necrosis of tumor tissue and the production of local tumor protein debris. These fragments of tumor protein debris contain a large number of various antigens, which can stimulate a specific cellular immune response. In the present study, dendritic cells (DCs) were loaded with tumor protein lysate antigens that were produced by RFA, and were used to treat murine colon carcinoma in combination with cytokine-induced killer (CIK) cells.

PD-1/PD-L1 pathway in non-small-cell lung cancer and its relation with EGFR mutation.

Coplanar VMAT vs. noncoplanar VMAT in the treatment of sinonasal cancer.

Background: Previous studies showed that noncoplanar intensity-modulated radiotherapy (NC-IMRT) for sinonasal cancer is superior to coplanar intensity-modulated radiotherapy (IMRT). Volumetric-modulated arc therapy (VMAT) is a newly introduced treatment modality, and the performance of noncoplanar VMAT for sinonasal cancer has not been well described to date.

Purpose: To compare the dosimetry difference of noncoplanar VMAT (NC-VMAT), coplanar VMAT (co-VMAT), and NC-IMRT for sinonasal cancer.

Evaluation of tumor response to cytokine-induced killer cells therapy in malignant solid tumors.

CIK cells therapy has been evaluated as an adoptive cell immunotherapy for cancer patients, but there still have not been any standardized systems for evaluating the antitumor efficacy yet. The WHO and RECIST criteria have already been established for a few years but not sufficient to fully characterize the activity of immunotherapy. Based on these two criteria, the irRC was proposed for evaluating the efficacy of immunotherapy.

Mechanism of T cell regulation by microRNAs.

MicroRNAs (miRNAs) are small, non-coding single-stranded RNAs that can modulate target gene expression at post-transcriptional level and participate in cell proliferation, differentiation, and apoptosis. T cells have important functions in acquired immune response; miRNAs regulate this immune response by targeting the mRNAs of genes involved in T cell development, proliferation, differentiation, and function. For instance, miR-181 family members function in progression by targeting Bcl2 and CD69, among others.

Expression of costimulatory molecule B7-H4 in human malignant tumors.

Costimulatory molecule B7-H4, a member of the B7 family, negatively regulates the immune response of T cells through inhibiting their proliferation, cytokine production and cell cycle. The overexpression of B7-H4 plays an important role in initiation, progression and regression of tumors by promoting malignant transformation of epithelial cells and protecting epithelial cells from anoikis. B7-H4 expression in malignant tumors is useful for clinical diagnosis, and may provide a novel molecular target for cancer treatment.

Higher numbers of T-bet(+) intratumoral lymphoid cells correlate with better survival in gastric cancer.
