Skin cancers remain the most common group of cancers globally, and the incidence continues to rise. Although localized skin cancers tend to have excellent outcomes following surgical excisions, the less common cases that become surgically unresectable or metastatic have been associated with poor prognosis and suboptimal treatment responses to cytotoxic chemotherapy. Development of monoclonal antibodies to programmed cell death-1 receptor and its ligand (PD-1/PD-L1) have transformed the management of metastatic melanoma, squamous cell carcinoma, and Merkel cell carcinoma.

Electronic address:

Nasopharyngeal carcinoma (NPC) is relatively sensitive to ionizing radiation, and radiotherapy is the main treatment modality for non-metastatic NPC. Radiation therapy generates overproduction of reactive oxygen species (ROS), which can cause DNA damage and induce apoptosis in tumors, thereby killing the malignant cells. Although dietary antioxidant supplementation reduces oxidative stress and promotes tumor progression, the effects of antioxidants on the NPC cells upon radiation have not been reported. Read More

Metastatic disease represents a serious and often fatal development in patients with solid tumors, including women with breast cancer and dogs with mammary tumors. Therefore, preventing and treating metastatic disease has remained a priority in cancer research. Desmopressin, a synthetic derivative of vasopressin, traditionally used to treat patients with bleeding disorders, has been proposed as a potential antimetastatic agent due to its effect on hemostasis as well as multiple other antiproliferative and antiangiogenic mechanisms.

Background: There is increasing evidence that immunotherapy with nivolumab, an anti-programmed death 1 monoclonal antibody, is effective in the treatment of recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). However, the predictive role of hematological inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and the modified Glasgow prognostic score (mGPS) in patients with R/M SCCHN treated with nivolumab remains unclear.

Methods: We conducted a multi-institutional cohort study to evaluate the impact of pretreatment NLR and mGPS on overall survival (OS) and progression-free survival (PFS) in patients with R/M SCCHN treated with nivolumab in Japan. Read More

Tissue-resident memory (Trm) cells are specialized components of both CD4+ and CD8+ T cell subsets that persist in peripheral non-lymphoid tissues following infections and provide fast response in case of a secondary invasion by the same pathogen. Trm cells express the surface markers CD69, CD103 and the immune checkpoint molecule PD-1. Trm cells develop not only in the context of infections but also in tumors, where they can provide a line of defense as suggested by the positive correlation between the frequency of tumor-infiltrating Trm cells and patients' survival.

Background And Aims: Surgical resection for patients with intermediate hepatocellular carcinoma (HCC) is preferred in China, but the prognosis remains far from satisfactory. Postoperative transarterial chemoembolization (p-TACE) has been conducted prevalently to prevent recurrence, but its efficacy remains controversial. Hence, we collected the data from primary liver cancer big data (PLCBD) to investigate the clinical value of p-TACE for patients with intermediate HCC and identify the potential beneficiaries.

Introduction: A poor prognosis owing to cancer invasion and metastasis, hepatocellular carcinoma (HCC) is one of the leading causes of malignancy deaths worldwide. A dominant epithelial-to-mesenchymal transition or EMT function in tumour metastasis is substantially evidenced. Prior reports identified a likely correlation of the nuclear hormone receptor with HCC progression, but the underlying molecular mechanisms and role of invasion and metastasis are still to be adequately documented.

Background: Collecting duct carcinoma (CDC) of the kidney is a rare and highly aggressive malignant tumor with the worst prognosis among all renal cancers. Nevertheless, the first-line treatments, including chemotherapy and target therapy, usually show poor response to CDC.

Lesions of the Ampulla of Vater are a rare condition and represent <10% of peri-ampullary neoplasms. Nevertheless, ampullary adenomas have the potential for malignant transformation to ampullary carcinomas by an adenoma-to-carcinoma sequence. Thus, adequate patient selection and complete resection (R0) of non-invasive ampullary lesions either by endoscopic papillectomy (EP), surgical ampullectomy (SA), or pancreaticoduodenectomy (PD) is essential.

Metastatic cancer that involves the structures of the heart is a rare complication and most commonly diagnosed during postmortem examination. Classically, the development of secondary tumors involves invasion of the pericardium or the myocardium and may disrupt the cardiac conduction system, causing new arrhythmias and heart failure.

Therapeutic options for advanced, unresectable hepatocellular carcinoma (HCC) have changed dramatically over the last 3 years. While surgical resection, orthotropic liver transplantation, and localized therapeutic options such as ablation, radiation therapy, and embolization remain therapeutics of choice in localized disease, systemic therapy is the only option in advanced, metastatic HCC. Since the United States Food and Drug Administration (US FDA) approval of sorafenib in 2008, targeted therapies such as sunitinib, tivantinib, brivanib, erlotinib, and linifanib; monoclonal antibody- bevacizumab showed no meaningful improvement in treatment of HCC.
