INTRODUCTION: Despite the human papillomavirus conferring a better prognosis in the primary treatment setting, the prognostic impact of viral status after treatment failure in oropharyngeal squamous cell carcinoma patients is poorly understood. METHODS: We retrospectively identified 33 oropharyngeal squamous cell carcinoma (OPC) patients with local and/or distant disease recurrence post-treatment, and looked at metastatic patterns, time to failure and survival patterns by HPV status...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

OBJECTIVE: To assess the patterns and predictors of metastatic disease in renal cell carcinoma (RCC) at the time of diagnosis in a contemporary series. METHODS: The Surveillance, Epidemiology, and End Results database was queried for all patients with kidney RCC from 2010 to 2013 (N = 50,815). Distribution and predictors of distant metastases at diagnosis were assessed. Multivariate logistic regression hazard analyses were performed to determine covariates associated with the likelihood of having metastases at diagnosis, whereas competing risks regression analysis was used to assess predictors of cancer-specific mortality (CSM) in patients with metastatic disease...

Laryngeal cancer is the 14th most common malignancy worldwide, and its common subtype squamous cell carcinoma (SCC) is highly associated with tobacco use and long-term alcohol consumption. The incidence of distant metastasis from a primary laryngeal cancer has been reported to be very low, between 6.5% and 8.5%, according to published tumour registry data. Distant metastases of laryngeal SCC most commonly involve the lung, liver, bone and mediastinum, seldom involving the kidney. Renal metastasis has been well established in many other cancers such as lymphoma, lung, breast and gastric carcinoma...

BACKGROUND: Phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 1 (P-Rex1) has been implicated in cancer growth, metastasis, and response to phosphatidylinositol 3-kinase (PI3K) inhibitor therapy. The aim of this study was to determine whether P-Rex1 expression differs between primary and metastatic human breast tumors and between breast cancer subtypes. DESIGN: P-Rex1 expression was measured in 133 specimens by immunohistochemistry: 40 and 42 primary breast tumors from patients who did versus did not develop metastasis, respectively, and 51 breast-derived tumors from metastatic sites (36 of which had matching primary tumors available for analysis)...

Tumor-induced bone disease is common among patients with advanced solid cancers, especially those with breast, prostate, and lung malignancies. The tendency of these cancers to metastasize to bone and induce bone destruction is, in part, due to alterations in integrin expression and signaling. Substantial evidence from preclinical studies shows that increased expression of integrin αvβ3 in tumor cells promotes the metastatic and bone-invasive phenotype. Integrin αvβ3 mediates cell adhesion to several extracellular matrix proteins in the bone microenvironment which is necessary for tumor cell colonization as well as the transmission of mechanical signals for tumor progression...

CXCR4 and its ligand CXCL12 play a critical role in the metastasis of various types of cancer including breast cancer. Breast tumors preferentially metastasize to the lung, bones and distant lymph nodes, secreting high levels of CXCL12. We hypothesized that targeted inhibition of CXCR4 in breast cancer cells should suppress CXCR4-positive tumor cells toward secondary metastatic sites. In the present study, the efficacy of CXCR4 targeted dendrimers carrying DOX (LFC131-DOX-D4) on cellular binding, cytotoxicity, and migration of BT-549-Luc and T47D breast cancer cells was investigated...

Paget Disease of the bone is a metabolic disorder which leads to a profound alteration of the bone's architecture. It may be asymptomatic and, since its radiological features mimic those of bone metastases, may present a diagnostic dilemma during the evaluation of a cancer patient. We illustrate an uncommon monostotic form of the disease, affecting solely the scapula, diagnosed during the staging of a lung cancer patient.

The current study presents the case of a 66-year-old male presenting with fever and chest pain. Chest enhanced computed tomography scanning revealed a mass shadow in the right upper lobe with chest wall invasion. 18-Fluorodeoxyglucose-positron emission tomography (FDG-PET) identified the localized uptake of the mass lesion in the right upper lobe, in addition to diffuse uptake by the bone marrow. The laboratory data on admission revealed marked leukocytosis and an elevated C-reactive protein level (CRP). Serum concentrations of granulocyte colony-stimulating factor (G-CSF) and interleukin 6 were increased...

Pancreatic cancer (PaCa) has a dismal prognosis and adjuvant immunotherapy frequently is of low efficacy due to immunosuppressive features of PaCa and PaCa-stroma. We here explored, whether the efficacy of vaccination with tumor-exosome (TEX)-loaded dendritic cells (DC) can be improved by combining with drugs affecting myeloid-derived suppressor cells (MDSC). Experiments were performed with the UNKC6141 PaCa line. UNKC6141 TEX-loaded DC were weekly intravenously injected, mice additionally receiving Gemcitabine (GEM) and/or ATRA and/or Sunitinib (Sun)...

Lung cancer is a malignant tumor with high metastatic ability and bone is the most common site of distant metastasis of it. However, the independent risk factors for bone metastases of lung cancer remain largely to be elucidated. Here, we conducted a retrospective study to evaluate the correlation between clinical-pathological parameters, serum levels of neuron-specific enolase and CYFRA21-1, and bone metastases in lung cancer patients. The results revealed that patients with bone metastases were younger than those without metastases...

BACKGROUND/AIM: Fatty liver disease is increasing in the developed and developing world. Liver metastasis from malignant lymphoma in the fatty liver is poorly understood. In a previous report, we developed color-coded imaging of the tumor microenvironment (TME) of the murine EL4-RFP malignant lymphoma during metastasis, including the lung. In the present report, we investigated the potential and microenvironment of the fatty liver induced by a choline-deficient diet as a metastatic site in this mouse lymphoma model...

Eccrine carcinoma is an extremely rare malignant skin cancer arising from eccrine sweat glands with a high metastatic potential. It mainly occurs in the elderly, with equal incidence in both sexes. It usually spreads to regional lymph nodes, with liver, lungs, and bones being the most common sites of distant metastasis. Because of tumor rarity, little is known about the value of F-18 FDG PET/CT in evaluating this disease. Our case report aims to increase current knowledge of F-18 FDG PET/CT in eccrine sweat gland carcinoma as a noninvasive imaging tool for assessing the extension of the disease and detecting distant metastases...

The worst complication of cancer is represented by its spread to distant sites. In particular, bone provides a fertile soil for several cancer types, especially those derived from breast, prostate and lung tumours. Despite the progress in diagnostic and therapeutic strategies, bone metastases (BM) still impact on quality of life and overall survival, making it necessary to identify the "high-risk" patients at an earlier stage. Since BM affect physiological bone turnover, measurement of bone turnover markers (BTM) has been widely investigated for diagnostic and prognostic purposes, as well as to support the development of anti-cancer drugs...
