PURPOSE: The staging of multiple pulmonary adenocarcinomas requires the distinction of intrapulmonary metastasis (IPM) from multiple primary lung cancers (MPLC). This can be challenging in some patients, and the addition of data from oncogenic driver mutations in these tumors may be helpful in this determination. PROCEDURES: As a proof of principle, molecular driver results from primary tumors and their metastases in 45 patients were compared (cohort 1). Then, 69 patients with a total of 154 synchronous or metachronous lung carcinomas were identified, with pathologic findings compared to oncogenic driver mutation...

The overexpression of survivin in breast cancer cells is an important factor of paclitaxel (PTX) resistance in breast cancer. To overcome PTX resistance and improve the antitumor effect of PTX, we developed a novel liposome-based nanosystem (PTX/siRNA/SS-L), composed of a redox-sensitive cationic oligopeptide lipid (LHSSG2C14) with a proton sponge effect, natural soybean phosphatidylcholine (SPC), and cholesterol for co-delivery of PTX and anti-survivin siRNA, which could specifically downregulate survivin overexpression...

Emerging evidence suggests that the tumour microenvironment plays a critical role in osteosarcoma (OS) development. Thus, cytokine immunotherapy could be a novel strategy for OS treatment. In this study, we explored the role of macrophage migration inhibitory factor (MIF), an important cytokine in OS progression, and investigated the anti-tumour effects of targeting MIF in OS. The results showed that MIF significantly increased in the tissue and serum samples of OS patients and was associated with tumour size, pulmonary metastasis and the survival rate of OS patients...

Introduction Pseudotumour of the lung is a collective term for various subentities. Some subgroups are considered to be intermediary malignant tumours. A pseudotumour is a rare condition, which makes it difficult to estimate its incidence and prevalence. Methods Retrospective analysis of all surgically treated patients between 2008 and 2015 diagnosed with a pseudotumour of the lung. The primary endpoint of this study was to estimate the rates of local recurrence and metastasis. Secondary endpoints were to determine the nomenclature, medical history, treatment, and the perioperative course...

RATIONALE: BRAF and MEK inhibitors have significantly improved the prognosis of metastatic melanoma, by inhibiting both the mitogen-activated protein kinase (MAP-kinase) pathway. They are associated with infrequent adverse kidney events. Most of these are related to the use of BRAF inhibitors and involve interstitial nephritis with acute tubular necrosis. PATIENT CONCERNS: We report a unique case of glomerulonephritis with renal granulomatous vasculitis in a patient diagnosed with metastatic melanoma treated with BRAF and MEK inhibitors...

The known oncogene cyclin D1 (CCND1) participates in progression of the cell cycle from G1 to S phase. Expression of cyclin D1 is frequently promoted in multiple human cancers including non-small cell lung cancer (NSCLC). However, a relationship between cyclin D1 expression and the prognosis of NSCLC has not been confirmed. NKX2-1 is a homeobox transcription factor involved in pulmonary development as a differentiation-promoting factor. In NSCLC, it acts as a metastasis suppressor and correlates with a good prognosis...

Giant cell tumor of bone is a rare but aggressive benign tumor that arises at the end of long tubular bones. The tumor rarely metastasizes; however, we report a case in which a giant cell tumor of bone presented with progressive pulmonary metastases. There has been no clear pathologic evidence of the definitive cause or route of metastasis. In our case, the primary tumor site was located in the left femur with pathological evidence of blood vessel invasion. The histological and pathological features of this entity are discussed in this letter to the editor...

Carcinoid tumors are uncommon neoplasms of neuroendocrine origin that generally arise in the gastrointestinal or bronchopulmonary tracts and typically are characterized by an indolent clinical course. Metastases from these primary neoplasms more commonly affect the viscera, with rare reports of cutaneous metastases to the skin. We report the case of a patient with a cutaneous carcinoid metastasis that was incidentally brought to our attention because of the exquisite tenderness of the lesion. A brief review of the literature also is provided...

In recent years, the spread of more-sensitive diagnostic methods has resulted in an increase of synchronous multiple primary lung cancer diagnosis. Nevertheless, its occurrence is still rare. Distinction between synchronous lesions from second independent primary tumors is a problem when dealing with multiple lung tumors, particularly if the histological type is the same. We present a case report of a 78-year-old female patient referred to our institution due to pneumonia. A subsequent thoracic computed tomography (CT) was performed showing two suspicious lesions, one in the right upper lobe and the other in the right inferior lobe...

Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

We report a rare case of squamous cell carcinoma (SCC) in bladder diverticulum producing granulocyte colony stimulating factor (G-CSF). A 59-year-old man complaining of hematuria and right hip pain was admitted with a large cancer in the bladder diverticulum. His laboratory data showed leukocytosis of 20,100/ μ l (neutrophils : 92%) with an elevated G-CSF of 76. 6 pg/ml in the peripheral blood. After neoadjuvant chemotherapy (gemcitabine and cisplatin), radical cystectomy was performed to normalize serum leukocytosis and G-CSF...

Osteosarcoma is a kind of primary malignant bone tumor with the highest incidence and an extraordinarily poor prognosis and early pulmonary metastasis formation as a frequent occurrence. Transcriptional positive coactivator 4 (PC4) has multiple functions in DNA replication, transcription, repair and chromatin organization, even in tumorigenesis. However, the precise function of PC4 in osteosarcoma is still unclear and controversial. In this paper we found PC4 was upregulated in patient-derived osteosarcoma tissues compared to normal...

Programmed cell death-ligand 1 (PD-L1) expression is commonly observed in non-small cell lung cancer (NSCLC). The prognostic value of PD-L1 expression and the maximum standardized uptake value (SUVmax) on 18F-Fluorodeoxyglucose positron emission tomography (18FDG-PET) in surgical pulmonary squamous cell carcinoma(SCC)remains unclear. Furthermore, the correlation between the SUVmax and PD-L1 expression has not been assessed. Thus, the purpose of this study was to investigate the correlation between PD-L1 expression and the SUVmax on 18FDG-PET and to examine the prognostic significance of PD-L1 expression and the SUVmax in surgical pulmonary SCC...

Efficacious therapies for measurable metastatic canine osteosarcoma (OSA) are generally lacking. Preliminary retrospective studies suggested that approximately 50% of dogs with measurable metastatic OSA experienced clinical benefit (objective response or clinically meaningful disease stabilisation) following toceranib (TOC) treatment. The purpose of this clinical trial was to prospectively evaluate the clinical outcome following TOC treatment in dogs with measurable pulmonary metastatic OSA. A secondary goal was to identify potential biomarkers of clinical benefit by measuring changes in plasma vascular endothelial growth factor (VEGF) and circulating regulatory T-cell (Treg) percentage...

Urothelial carcinoma (Transitional cell carcinoma) of the bladder is the pre-dominant histological type of bladder cancer in the United States and Europe. Patients with bladder cancer usually present with painless hematuria. The diagnosis is often delayed, as the symptoms are similar to various other benign conditions such as urinary tract infection, prostatitis or renal calculi. In some patients, the metastatic lesions will cause the initial presenting symptoms. We conducted a MedLine/PubMED search identifying all relevant articles with "pulmonary manifestations", "urothelial bladder cancer", "manifestations of bladder cancer" or a combination of these terms in the title...

The SASH1 gene is discovered as a tumor suppressor recently. However, the molecular mechanisms of SASH1 in hepatocarcinoma (HCC) remain unclear. In present studies, we investigated the molecular mechanisms of SASH1 on cell invasion and metastasis of hepatocarcinoma in vivo and in vitro. In this study, SASH1 overexpression HCC cell lines were treated with purmorphamine (0, 0.5, 1, 2μmol/l). Western blot and qRT-PCR were used to examine the related gene expression of EMT markers and the Shh-Gli1 and PI3K/Akt-dependent pathway...
