Salivary gland carcinomas are rare tumors, representing ~0.5% of all malignancies. Myoepithelioma is also uncommon, representing ~1% of all salivary gland tumors. Myoepithelial carcinoma (MC) is even rarer, representing 0.2 to 0.6% of all salivary gland tumors. We herein report a case of MC with multiple metastases arising from a submandibular gland in a 71-year-old male patient and present the associated imaging findings. The patient was considered to have a de novo type of myoepithelial carcinoma, which is reportedly associated with higher malignancy than the transformation type of the disease (i...

Re-education of tumor-associated macrophages (TAMs) toward antitumor effectors may be a promising therapeutic strategy for the successful treatment of cancer. HangAmDan-B (HAD-B), a herbal formula, has been used for stimulating immune function and activation of vital energy to cancer patients in traditional Korean Medicine. Previous studies have reported the anti-angiogenic and anti-metastatic effects of HAD-B; however, evidence on the immunomodulatory action of HAD-B was not demonstrated. In the present study, immunocompetent mice were used to demonstrate the suppression of the in vivo growth of allograft Lewis lung carcinoma (LLC) cells, by HAD-B...

The aim of the present study was to explore use of the acridine orange fluorescence (AO-F) staining method for screening of circulating tumor cells (CTCs) in renal cell carcinoma (RCC) patients. The AO-F positive staining rate of live and dead tumor cells was calculated. The positive staining rate in the live group was 93.4±3.0%, while the dead group failed to emit specific fluorescence. A known number of tumor cells were added to peripheral blood, and the detection sensitivity of the four groups (50, 100, 200 and 500 cells/tube) was 10...

Melatonin, synthesized in and released from the pineal gland, has been demonstrated by multiple in vivo and in vitro studies to have an oncostatic role in hormone-dependent tumors. Furthermore, several clinical trials point to melatonin as a promising adjuvant molecule to be considered for cancer treatment. In the past few years, evidence of a broader spectrum of action of melatonin as an antitumor agent has arisen; thus, melatonin appears to also have therapeutic effects in several types of hormone-independent cancer, including ovarian, leukemic, pancreatic, gastric and non-small cell lung carcinoma...

Survival rates in patients with stage IIIA non-small cell lung cancer (NSCLC) remain low despite curative treatment. This is due to tumor recurrence at distant sites. The aim of neoadjuvant chemotherapy (NA-CT) is to eradicate occult micrometastatic disease and improve survival in patients that are not candidates for surgery following induction therapy. A total of 21 patients with ipsilateral mediastinal node involvement (N2) with potentially resectable disease, who had been diagnosed with stage IIIA (T1-3 N1-2 and T4N0) NSCLC and who had received cisplatin and vinorelbine as induction treatment were included in this retrospective study...

The inhibitor of growth family, member 3 (ING3) protein may be capable of blocking the cell cycle via activating p53-transactivated promoters of p21 and Bcl2-associated X protein, and may induce apoptosis via a Fas/caspase-8-dependent signaling pathway. In the present study, immunohistochemistry was performed in order to characterize the expression profile of ING3 protein in tissue microarrays containing mouse and human normal tissue, human hepatocellular (n=62), renal clear cell (n=62), pancreatic (n=62), esophageal squamous cell (n=45), cervical squamous cell (n=31), breast (n=144), gastric (n=196), colorectal (n=96), ovarian (n=208), endometrial (n=96) and lung carcinoma (n=192)...

Platinum-based drugs, including cisplatin (DDP) and oxaliplatin (L-OHP), are among the most potent chemotherapy drugs, and are widely utilized for the treatment of human lung and ovarian cancer. However, certain patients do not respond to platinum-based agents, and even those who initially benefit from the treatment will eventually exhibit resistance to these drugs. Although certain factors have been investigated for their potential to predict platinum resistance, more effective predictors for the improved management of patients with lung and ovarian cancer are required...

The homeobox-containing gene HOXB7 plays an important role in the pathogenesis and progression of many cancers, yet its role in hepatocellular carcinoma (HCC) remains unclear. This study comprehensively analyzed the expression and clinical significance of HOXB7 in HCC and explored its potential mechanism in tumor progression. We found HOXB7 was highly expressed in HCC cell lines with highly metastatic potential and cancerous tissues from patients with tumor recurrence. The abilities of proliferation, migration, and invasion were notably decreased by depletion of HOXB7, and were enhanced by its enforced expression in vitro...

Distinguishing synchronous and metachronous primary lung adenocarcinomas from adenocarcinomas with intrapulmonary metastasis is essential for optimal patient management. In this study, multiple lung adenocarcinomas occurring in the same patient were evaluated using comprehensive histopathologic evaluation supplemented with molecular analysis. The cohort included 18 patients with a total of 52 lung adenocarcinomas. Eleven patients had a new diagnosis of multiple adenocarcinomas in the same lobe (n=5) or different lobe (n=6)...

Selected reaction monitoring mass spectrometry (SRM-MS) -based semi-quantitation was performed to assess the validity of 46 selected candidate proteins for specifically diagnosing large-cell neuroendocrine lung carcinoma (LCNEC) and differentiating it from other lung cancer subtypes. The scaling method was applied in this study using specific SRM peak areas (AUCs) derived from the endogenous reference protein that normalizes all SRM AUCs obtained for the candidate proteins. In a screening verification study, we found that seven out of the 46 candidate proteins were statistically significant for the LCNEC phenotype, including 4F2hc cell surface antigen heavy chain (4F2hc/CD98) (p-ANOVA ≤ 0...

OBJECTIVE: The aim of this study was to describe the characteristics of lung cancers in patients with tuberculous fibrothorax or empyema. METHODS: We retrospectively evaluated 138 consecutive patients with a diagnosis of lung cancer combined with fibrothorax (n = 127) or empyema (n = 11) from January 2005 to May 2015. All patients underwent computed tomography, and 105 underwent F-fluorodeoxyglucose positron emission tomography. Clinical, pathologic, and computed tomography characteristics and maximum standardized uptake values on positron emission tomography of 76 cancers ipsilateral to the fibrothorax or empyema (group 1) were compared with those of 62 contralateral cancers (group 2)...

Renal cell carcinoma (RCC) affects > 60,000 people in the United States annually, and ~ 30% of RCC patients have multiple metastases at the time of diagnosis. Metastatic RCC (mRCC) is incurable, with a median survival time of only 18 months. Immune-based interventions (e.g., interferon (IFN) and interleukin (IL)-2) induce durable responses in a fraction of mRCC patients, and multikinase inhibitors (e.g., sunitinib or sorafenib) or anti-VEGF receptor monoclonal antibodies (mAb) are largely palliative, as complete remissions are rare...

Antisynthetase syndrome is a heterogeneous idiopathic inflammatory myopathy. Anti-Jo1 is the most common antibody found in this condition. Dermatomyositis is known to be associated with malignancy, but the association between antisynthetase syndrome and malignancy is not clearly established. We report a case of an association of squamous cell carcinoma of the lung and anti-Jo1 antisynthetase syndrome. A 67-year-old man presented with polyarthritis, muscle weakness of the pelvic girdle, "mechanic's hands," and weight loss...

Cisplatin-based combination chemotherapy significantly improves the survival outcomes in non-small cell lung carcinomas (NSCLCs), but drug resistance commonly contributes to disease progression and relapse. Recently, accumulating evidence has indicated that deubiquitinases (DUBs) are involved in regulating tumor cell proliferation, apoptosis, and chemoresistance. We designed this study to investigate the role of WP1130, a DUB inhibitor, in regulating cisplatin cytotoxicity in NSCLCs. After being combined with WP1130, cisplatin sensitivity was significantly increased in A549 and HCC827 cells with decreased p53 expression, inhibiting their proliferation, but not in p53-deficient NCI-H1299 cells...

Immunometabolism is emerging as a critical determinant of cancer pathophysiology. In this study, we explored the contributions of macrophage-expressed lactate dehydrogenase-A (LDH-A) to tumor formation in a K-Ras murine model of lung carcinoma. Myeloid-specific deletion of LDH-A promoted accumulation of macrophages with a CD86high and MCP-1high M1-like phenotype that suppressed tumor growth. This phenotypic effect was accompanied by reduced VEGF expression and angiogenesis; diminished numbers of PD-L1+ cancer cells; increased numbers of CD3+ T cells and activation status of CD8+ T cells...

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the standard first line treatment for advanced non-small cell lung cancer (NSCLC) with sensitive EGFR mutations. Among NSCLC, giant cell carcinoma of the lung (GCCL) is a rare pathological subtype with poor prognosis, with no confirmed evidence about its epidemiological features or therapeutic efficiency of EGFR-TKIs. We present two advanced GCCLs with sensitive EGFR mutations, also collected the cases of GCCL from our hospital and the Surveillance, Epidemiology, and End Results (SEER) program...

Human microRNA-125a-5p (miR-125a) is expressed in most tissues where it downregulates the expression of membrane receptors or intracellular transductors of mitogenic signals, thus limiting cell proliferation. Expression of this miRNA generally increases with cell differentiation whereas it is downregulated in several types of tumors, such as breast, lung, ovarian, gastric, colon, and cervical cancers, neuroblastoma, medulloblastoma, glioblastoma, and retinoblastoma. In this study, we focused on hepatocellular carcinoma and used real-time quantitative PCR to measure miR-125a expression in 55 tumor biopsies and in matched adjacent non-tumor liver tissues...

Highly effective and attenuated dose schedules are good regimens for drug research and development. Combination chemotherapy is a good strategy in cancer therapy. We evaluated the antitumour effects of dihydroberberine combined with sunitinib (DCS) on the human non-small cell lung cancer cell lines (NSCLC), A549, NCI-H460, and NCI-H1299 in vitro and in vivo. DCS showed synergic effects on NCI-H460 cell proliferation, colony formation and transplantable tumour growth, which suggested dihydroberberine increases the sensitivity of lung carcinoma to sunitinib...
