Microchimerism has generally been shown to protect against cancer (Gilmore et al. in Exp Hematol 36(9):1073-1077, 2008). The mechanism of how this occurs is an area of intense study, as it may lead to new cancer treatments. The leading theory is that microchimeric cells perform immune surveillance by directly fighting cancerous cells and that they also act as stem cells, repairing damaged tissue (Khosrotehrani et al. in JAMA 292:75-80, 2004). However, there is conflicting evidence to support this theory. Several small studies have found few microchimeric cells in tumor tissue (Gadi in Breast Cancer Res Treat 121(1):241-244, 2010; Cirello et al...

Survival in lung cancer patients is genetically determined. Single nucleotide polymorphisms (SNPs) in DNA repair genes are observed to play a critical role in survival as DNA repair itself can behave as double-edged sword. We aim to explore the association of DNA repair gene XRCC1 in survival and clinical outcomes for North Indian population. Blood sample from patients diagnosed with lung cancer was taken. DNA isolation and genotyping were performed for the SNPs of XRCC1 gene. Further, patients were followed up through telephonic conversation after every 2 months for 3 years...

Head and neck (H&N) cancer is an aggressive disease and the incidence has increased in younger population worldwide. Tumour TNM staging is the main basis for treatment decision despite significant variation in clinical outcome. Survival time of these patients has marginally improved during the last 30 years. Various biomarkers with cumbersome analysis, high cost, time consumption and requirement of special laboratory facilities have been investigated. However, none of these biomarkers have been shown to be suitable to use for individual H&N cancer patient treatment selection in the clinic...

Primary central nervous system lymphoma (PCNSL) is an extra-nodal non-Hodgkin lymphoma. PCNSL is defined as lymphoma involving the brain, leptomeninges, eyes, or spinal cord without evidence of lymphoma outside the CNS. Treatment includes induction with chemotherapy and consolidation with whole-brain radiotherapy or high-dose chemotherapy supported by autologous stem cell transplantation. High-dose methotrexate is the most important drug in cases with PCNSL, and this drug will be used in combination with small molecules, BTK inhibitors, new monoclonal antibodies, and checkpoint blockers...

Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous group of malignant tumours that affects over 500,000 patients per year. Treatment failure is generally due to the heterogeneity of these tumours and to the serious adverse effects associated with treatment. Immunological system impairment, which is common in HNSCC, further contributes to treatment failure by mediating tumour escape mechanisms. To date, the only clinically approved targeted therapy agent is cetuximab, a monoclonal antibody (mAb) that binds to, and inhibits, epidermal growth factor receptor, which is widely overexpressed in HNSCC...

Breast cancer is a disease of unknown etiology; however, the major risk factors are genetic alterations. Studies have demonstrated an association between insulin-like growth factor 1 (IGF-1) gene polymorphism and cell proliferation and reduced apoptosis, in addition to its role in breast cancer growth and aggressiveness. Two polymorphic variants of the IGF-1 gene are highlighted in association with breast cancer, rs6220 and rs7136446, although controversy exists as to this relationship. The current study included 137 women (68 breast cancer cases and 69 controls without breast cancer) who had 3 ml of peripheral blood drawn for the study of genomic DNA extracted from leukocytes using the genotyping technique by real-time polymerase chain reaction...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems...

Reactive oxygen species (ROS) is excessively generated in tumors creating an oxidative stress in tumor microenvironment. We investigated hepatic expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and 8-hydroxydeoxyguanosine (8-OHdG) in hepatocellular carcinoma (HCC) patients, and asked if ROS epigenetically upregulated Nrf2 and enhanced aggressiveness in HCC cells. Expression of Nrf2 (n = 100) and 8-OHdG (n = 53) was remarkably increased in HCC tissues compared with the noncancerous hepatic tissues...

Germ cell tumors (GCTs) are one of the more curable solid cancers in men. Approximately 8500 men are diagnosed with GCTs in the USA. The majority of patients survive due to the availability of effective treatment. Fewer than 400 men are estimated to die from their disease. Among those, there is a subset of patients with metastatic GCTs receiving chemotherapy who rapidly develop progressive respiratory failure and die during the early phase of their treatment course. In this review, we searched the available literature for reported cases and retrospective series of chemotherapy-associated acute respiratory distress syndrome in GCTs...

Uterine fibroids are common benign tumors of unclear etiopathology that affect the female reproductive tract. They are responsible for considerable morbidity and deterioration of life quality, and may have a negative impact on the reproductive system as well. Besides surgery aided by uterus-saving techniques, several minimally invasive procedures are now available within the field of interventional radiology that represent a valid solution for women who desire pregnancy and relief from disease-specific symptomatology...

Cetuximab is approved for treatment of squamous cell carcinoma of the head and neck (SCCHN). Cetuximab is generally well tolerated, but does carry a black box warning for infusion reactions (IRs). Incidence of IR in clinical trials was 15-20% for all grades and 3-5% for grades III-IV. Retrospective studies reported a higher incidence of all grade IRs and grades III-IV IR in areas of the Southeastern United States. Information regarding rechallenge doses after an IR has not been well described. At our institution, we frequently rechallenge on the same day after an initial IR...

Liver thermal ablation is an alternative treatment for hepatocellular carcinoma (HCC) and secondary liver malignancies. Microwave ablation (MWA) produces large ablation zones (AZ) in short time; however, AZ prediction is based on preclinical ex vivo models, rising concerns about reproducibility and safety in humans. We aimed to investigate the effects produced by a new-generation MWA system on human liver in vivo with different approaches (percutaneous or intraoperative) and liver conditions (cirrhosis or previous chemotherapy treatment), in comparison with manufacturer-provided predictions based on ex vivo animal models...

Drug therapy for non-small cell lung cancer consists mainly of platinum-based chemotherapy regimens. However, toxicity, drug resistance, and high risk of death have been seen in the clinic, which means there is a need for optimizing the use of medications. Platinum resistance could be mediated by a series of DNA repair pathways, and therefore, these pathways should be taken into account for optimizing drug using. The goal of pharmacogenomics is to elucidate genetic factors, such as DNA repair genes, which might underlie drug efficacy and effectiveness, and to improve therapeutic effects or guide personalized therapy as well...
