Positron emission tomography-computed tomography (PET-CT) is performed as the standard method for response assessment of diffuse large B cell lymphoma (DLBCL) patients. However, a substantial proportion of patients experience relapse even if they have achieved complete response (CR) defined by PET-CT. We validated the prognostic value of CR by PET-CT and applied the National Comprehensive Cancer Network-International Prognostic Index (NCCN-IPI) and cell of origin (COO) to patients with CR by PET-CT to evaluate their additional predictive ability for survival outcomes...

The clinical benefit of nab-paclitaxel monotherapy for recurrent/metastatic head and neck squamous cell carcinoma (RM-HNSCC) that progressed on other taxanes (cremophor-based paclitaxel or docetaxel) is unknown. A retrospective analysis of patients treated at a single institution with nab-paclitaxel for taxane-resistant RM-HNSCC. The exploratory hypothesis was that nab-paclitaxel would result in clinical benefit (tumor response) in patients with taxane-resistant RM-HNSCC. Twelve patients who were treated with nab-paclitaxel monotherapy for taxane-resistant RM-HNSCC and met all eligibility criteria were identified...

Pyrroline-5-carboxylate reductase 1 (PYCR1) is an enzyme involved in cell metabolism, which has been shown to be up-regulated in cancers. However, the functions of PYCR1 in prostate cancers (PCa) are still largely unknown. In the present study, we found that PYCR1 was highly expressed in prostate cancer tissues and then knocked down PYCR1 in PCa cell lines (DU145, PC-3 and LNCap) via lentivirus-mediated gene delivery and analyzed its biological function. Both qRT-PCR and western blotting indicated that PYCR1 was suppressed efficiently after sh-PYCR1 infection...

Cancers are the group of diseases, which arise because of the uncontrolled behavior of some of the genes in our cells. There are possibilities of gene amplifications, overexpressions, deletions and other anomalies which might lead to the development and spread of cancer. One of the most dangerous ways to the cancers is the mutations of the genes. The mutated genes can start unstoppable proliferation of cells, their uncontrolled motility, protection from apoptosis, the DNA mutation enhancement as well as other anomalies, leading to the cancer...

Energetic carbon ions (CI) offer great advantages over conventional radiations such as X- or γ-rays in cancer radiotherapy. High linear energy transfer (LET) CI can induce both endoplasmic reticulum (ER) stress and autophagy in tumor cells under certain circumstances. The molecular connection between ER stress and autophagy in tumor exposed to high-LET radiation and how these two pathways influence the therapeutic effect against tumor remain poorly understood. In this work, we studied the impact of autophagy and apoptosis induced by ER stress following high-LET CI radiation on the radiosensitivity of S180 cells both in vitro and in vivo...

The application of nanosecond pulsed electric fields (nsPEFs) is a novel method to induce the death of cancer cells. NsPEFs could directly function on the cell membrane and activate the apoptosis pathways, then induce apoptosis in various cell lines. However, the nsPEFs-inducing-apoptosis action sites and the exact pathways are not clear now. In this study, nsPEFs were applied to the human liver cancer cells HepG2 with different parameters. By apoptosis assay, morphological observation, detecting the mitochondrial membrane potential (ΔΨ m), intracellular calcium ion concentration ([Ca(2+)]i) and the expressions of key apoptosis factors, we demonstrated that nsPEFs could induce the morphology of cell apoptosis, the change in ΔΨ m, [Ca(2+)]i and the upregulation of some key apoptosis factors, which revealed the responses of liver cancer cells and indicated that cells may undergo apoptosis through the mitochondria-dependent pathway after nsPEFs were applied...

IL-33 is a member of the IL-1 family of cytokines, and no study has been performed to address its direct anti-tumor effect. This study is designed to investigate whether IL-33 has any direct effect on pancreatic cancer. Clonogenic survival assay, immunohistochemistry, TUNEL staining, proliferation, caspase-3 activity kits and RT-PCR were used to evaluate the effects of IL-33 on cell survival, proliferation and apoptosis of a pancreatic cancer cell line, MIA PaCa-2. We found that the percentage of colonies of MIA PaCa-2 cells, PCNA+ cells and the OD value of cancer cells were all decreased in the presence of IL-33...

MCM7 is one of the subunits of MCM2-7 complex, which is essential to DNA replication licensing and the control of cell cycle progression. It has been demonstrated that MCM7 participates in mRNA transcription and DNA damage regulation as well. MCM7 gene is found to be over-expressed in multiple cancers, but there are few reports about its effect in leukemia. Recent studies have proven that MCM7 expression has a relationship with diagnosis and prognosis, which has led to their potential clinical application as a marker for cancer screening...

Micro-RNAs (miRNAs) have a complex role in carcinogenesis and tumour progression. Several miRNAs, such as miR-221, miR-27b and miR-132, have been implicated in the regulation of VEGF tumour angiogenic activity. In this pilot study, we assessed angiogenesis and DLL4+ vascular maturation index (VMI) in breast cancer tissues, in parallel with the plasma levels of the above-mentioned miRNAs. Significantly higher than control samples pre-operative levels were recorded in 10/11, 7/11 and 9/11 cases for the miR-221, miR-27b and miR-132, respectively...

The cancer community continues to search for an efficient and cost-effective technique to isolate and characterize circulating cells (CTCs) as a 'real-time liquid biopsy'. Existing methods to isolate and analyze CTCs require various transfer, wash, and staining steps that can be time consuming, expensive, and led to the loss of rare cells. To overcome the limitations of existing CTC isolation strategies, we have developed an inexpensive 'lab on a chip' device for the enrichment, staining, and analysis of rare cell populations...

Cutaneous melanoma (CM) cells are resistant to apoptosis, and steroid hormones are involved in this process through regulation of TP53, MDM2, BAX, and BCL2 expression. We analyzed herein sex differences in outcomes of CM patients associated with TP53 c.215G>C, MDM2 c.309T>G, BAX c.-248G>A, and BCL2 c.-717C>A polymorphisms. DNA from 121 men and 116 women patients was analyzed by polymerase chain reaction and enzymatic digestion assays. At 60 months of follow-up, shorter progression-free survival (PFS) was seen in males with MDM2 GG + BCL2 AA (20...

Autophagy is a catabolic process, which is involved in the maintenance of intracellular homeostasis by degrading redundant molecules and organelles. Autophagy begins with the formation of a double-membrane phagophore, followed by its enclosure, thus leading to the appearance of an autophagosome which fuses with lysosome. This process is highly conserved, precisely orchestrated and regulated by autophagy-related genes. Recently, autophagy has been widely studied in different types of cancers, including colorectal cancer...

c-Met plays a role as a prognostic marker in clear cell renal cell carcinoma. In addition, recently the tyrosine kinase inhibitor cabozantinib targeting c-Met was approved for the treatment of advanced renal cell carcinoma (RCC). In contrast to clear cell RCC, little is known about c-Met expression patterns in rarer RCC subtypes. The aim of this study was to evaluate the prevalence, distribution and prognostic impact of c-Met expression on chromophobe (ch)RCC. Patients who underwent renal surgery due to chRCC were retrospectively evaluated...

Epithelial cell transforming sequence 2 (Ect2) was originally reported as an oncogene that is involved in several types of human cancers. However, little is known about its expression and function in prostate cancer. Immunohistochemical staining for Ect2 was performed on a human tissue microarray. The staining intensity was analyzed in association with clinical pathological parameters such as Gleason score, pathological grade, clinical stage, tumor invasion, lymph node and distant metastasis. Furthermore, we repeated such analysis and investigated the prognostic value of Ect2 using the TCGA (The Cancer Genome Atlas) Dataset...

Circulating tumor cells (CTC) in the blood of cancer patients are regarded as potential metastatic seeds, and their detailed characterization holds great promises for more exact prognosis, better diagnosis and therapy of the metastatic cancer. Circulating tumor cell clusters represent different class of CTCs, with specific properties, including high metastatic potential. In this review, we present current opinions on differences between single CTCs and CTC clusters, their mode of dissemination, methods of detection and clinical importance in various types of cancer...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy after hepatocellular carcinoma. Complete surgical resection remains the only potentially curative option for patients with ICC. However, until now, early diagnosis with potential surgical intervention has been the exception rather than the rule with only 30% of patients qualifying for attempted surgical cure. Many patients are unresectable because of disease stage, anatomic conditions, medical comorbidities, and small future remnant liver...
