Immune checkpoint therapies target tumor antigen-specific T cells, but less is known about their effects on natural killer (NK) cells, which help control metastasis. In studying the development of lung metastases, we found that NK cells lose their cytotoxic capacity and acquire a molecular signature defined by the expression of co-inhibitory receptors. In an effort to overcome this suppressive mechanism, we evaluated NK cell responses to the immunostimulatory cytokine IL-12. Exposure to IL-12 rescued the cytotoxicity of NK cells but also led to the emergence of an immature NK cell population which expressed high levels of the co-inhibitory molecules PD-1, Lag-3 and TIGIT, thereby limiting NK cell-mediated control of pulmonary metastases...

Although 18F-5-fluoro-N-(2-[diethylamino]ethyl)picolinamide (18F-5-FPN) is considered a promising radiopharmaceutical for PET imaging of melanoma, it accumulates at high concentrations in the liver. The aim in this research was to optimize the structure of 18F-5-FPN with triethylene glycol to reduce liver uptake as well as improve pharmacokinetics, and to evaluate its performance in detection of melanoma liver and lung metastases. 18F-PEG3-FPN was successfully prepared with a high radiolabeling yield (44.68% ± 5...

Male breast cancer, which makes up approximately 1% of all breast cancers, is an aggressive disease with poor prognosis. We investigated the effects of dietary supplementation with selenium in the form of methylseleninic acid [(MSeA) 2.5 mg selenium/kg] on mammary tumorigenesis in male MMTV-PyMT mice. The mammary tumor latency was 14.6 weeks for the MSeA-fed group and 13.8 weeks for the controls fed the AIN93G diet (p < 0.05). Dietary supplementation with MSeA, versus the control, resulted in a 72% reduction in tumor progression, a 46% reduction in both final volume and weight of mammary tumors, and a 70% reduction in the number of lung metastases...

Clear cell renal cell carcinoma (ccRCC) is a gender-biased tumor. Here we report that there is also a gender difference between pulmonary metastasis and lymph node metastasis showing that the androgen receptor (AR)-positive ccRCC may prefer to metastasize to lung rather than to lymph nodes. A higher AR expression increases ccRCC hematogenous metastasis yet decreases ccRCC lymphatic metastases. Mechanism dissection indicates that AR enhances miR-185-5p expression via binding to the androgen response elements located on the promoter of miR-185-5p, which suppresses VEGF-C expression via binding to its 3' UTR...

Solitary breast metastases are rare and mimic primary breast carcinoma. A 60-year-old female with a history of pulmonary adenocarcinoma presented with a solitary left breast lump suspicious for malignancy on breast imaging. Core-needle biopsy disclosed an adenocarcinoma strongly and diffusely positive for oestrogen receptors. Further immunohistochemistry was consistent with the breast tumour being a solitary metastasis of her pulmonary cancer. Clinicians and pathologists should be aware of the fact that pulmonary adenocarcinomas may sometimes display strong rather than only focal positivity for oestrogen receptors by immunohistochemistry and may mimic breast cancer of no special type...

Pulmonary papillary adenoma is a rare tumor. Two cases without any clinical symptoms were enrolled in our hospital. Both cases were incidentally detected in pulmonary area by imaging. Pathological examination revealed well-circumscribed nodules consisting of papillary growth of cuboidal to low columnar epithelial cells lining the surface of the fibrovascular stroma. Immunohistochemistry (IHC) staining showed that the lining cells were diffusely positive for TTF-1, CK, p63, CK7, and Napsin A. The Ki-67 proliferation index was approximately 2%...

Presence of Met receptor tyrosine kinase in the nucleus of cells has been reported. However, the functions of Met which expresses in the nucleus (nMet) remain elusive. In this study, we found that nMet was increased in 89% of HCC tumorous tissues when compared with the corresponding non-tumorous liver tissues. nMet expression increased progressively along HCC development and significantly correlated with cirrhosis, poorer cellular differentiation, venous invasion, late stage HCC and poorer overall survival...

OBJECTIVES: The lung is one of the most common organs of metastasis from colorectal cancer (CRC), and we have encountered lung cancer patients with a history of CRC. There have been few studies regarding methods used to discriminate between primary lung cancer (PLC) and pulmonary metastasis from CRC (PM-CRC) based only on preoperative findings. We retrospectively investigated predictive factors discriminating between these lesions in patients with a history of CRC. METHODS: Between 2006 and 2015, 117 patients with a history of CRC (44 patients with 47 PLC and 73 patients with 102 PM-CRC) underwent subsequent or concurrent resection of pulmonary lesions...

It has been repeatedly shown that regular aerobic exercise exerts beneficial effects on incidence and progression of cancer. However, the data regarding effects of exercise on metastatic dissemination remain conflicting. Therefore, in the present study the possible preventive effects of voluntary wheel running on primary tumor growth and metastases formation in the model of spontaneous pulmonary metastasis were analyzed after orthotopic injection of 4T1 breast cancer cells into mammary fat pads of female Balb/C mice...

BACKGROUND: Thoracoscopic sublobar resections (TSLRs) are gaining popularity, but are challenging. However, despite technical difficulties, the reported rate of adverse events, complications, and unplanned procedures is low. To understand this paradox, we have studied our series of TSLRs. METHODS: We reviewed our prospective and intention-to-treat database on videothoracoscopic anatomical resections and extracted all planned thoracoscopic segmentectomies from January 2007 to July 2016...

Pulmonary Lymphangitic Carcinomatosis (PLC) occurs in about 6-8% of patients with lung metastasis and may rarely develop in the course of gastric cancer representing a complication due to diffuse metastasis in the lymphatics of the lungs. A 29-year-old female, admitted with difficulty in breathing and productive cough for one week, was initially evaluated for respiratory tract infection. During evaluation of associated anaemia an upper gastrointestinal endoscopy showed large ulcerative growth in the lesser curvature of the stomach suggestive of carcinoma...

Salivary adenoid cystic carcinoma (SACC) is associated with a high rate of lung metastasis. When lung metastasis occurs, the effects of traditional chemotherapy on SACC are poor. Hyperbranched polymer drug delivery (degradable hyperbranched polyglycerols, dHPGs) can be used as a strategy to load several drugs, and obtain beneficial effects on SACC lung metastasis through enhanced permeability and retention. In the present study, hydroxycamptothecin (HPT)-conjugated dHPG (dHPG-HPT) was synthesized and its effects on SACC xenografts in the lungs of nude mice were evaluated...

Liver cancer is the second leading cause of cancer death. Due to treatments failures from drug resistance and cancer metastasis, discovering more effective treatments is imperative. As an angiogenesis inhibitor extracted from the Chinese herb-Safflower, hydroxysafflor yellow A (HSYA) inhibits the tumor growth in H22-bearing mice. Poorly differentiated hepatoma cells showed the ability to invade and metastasize, which are dependent on the angiogenesis. Accordingly, we hypothesized that HSYA could inhibit the metastasis of liver cancer cells...
