The lungs are frequently affected by cancer metastasis. Although NRAS mutations have been associated with metastatic potential, their exact role in lung homing is incompletely understood. We cross-examined the genotype of various tumor cells with their ability for automatic pulmonary dissemination, modulated NRAS expression using RNA interference and NRAS overexpression, identified NRAS signali...
Chi3l1 is induced by a variety of cancers where it portends a poor prognosis and plays a key role in the generation of metastasis. However, the mechanisms that Chi3l1 uses to mediate these responses and the pathways that control Chi3l1-induced tumor responses are poorly understood. We characterized the mechanisms that Chi3l1 uses to foster tumor progression and the ability of the RIG-like helic...
PURPOSE The purpose of this study was to investigate the clinicopathological features of pulmonary metastasis from cervical cancer. MATERIALS AND METHODS We reviewed the medical records of 56 patients with cervical cancer who developed pulmonary metastasis after radical hysterectomy, postoperative concurrent chemoradiation or systemic chemotherapy between January 1990 and March 2014. RESULT...
PURPOSE Chest computed tomography is performed frequently for the preoperative pulmonary staging in colorectal cancers (CRCs) regardless of the result of chest x-ray (CXR) due to its high sensitivities and specificities. The advancement of CT technology detects more indeterminate lung lesions that may require further investigations, referrals and follow-up. The aim of this study was to suggest ...
Adenoid cystic carcinoma (ACC) is a malignancy of the secretory epithelial cells salivary glands and constitutes less than 1% all head neck tumors. Metastasis occurs frequently most commonly affects lungs at rate 35 to 50%. In this case report, we present rare nasopharyngeal ACC with distant metastasis liver. Our patient initially presented hospital dental sinus pain initial imaging suggesting ...
Miliary multi-focal bilateral pulmonary adenocarcinoma with lepidic predominant pattern is an unusual morphological presentation and is seen in females who are non-smokers. This gross morphology can be confused with infectious diseases, like tuberculosis, histoplasmosis or with pulmonary metastasis.
In the hepatocellular carcinoma (HCC) microenvironment, chemokine receptors play a critical role in tumorigenesis and metastasis. Our previous studies have found that osteopontin (OPN) is a promoter for HCC metastasis. However, the role of chemokine receptors in OPN-induced HCC metastasis remains unclear. In this study, we demonstrate that OPN is dramatically elevated in HCC tissues with metast...
introduction low-grade endometrial stromal sarcoma (lg-ess) is a malignant intrauterine tumor that rarely presents with distant metastasis. simultaneous lung and cardiac metastases from lg-ess is also an extremely rare event. case presentation a 42-year-old woman presented with dyspnea and exercise intolerance. she had a history of hysterectomy and left salpingoophorectomy. she underwent second...
Primary angiosarcoma of bone is very rare.It occurs more commonly in middle-age and later life, with a male predominance in the ratio of 2:1. Angiosarcoma of bone has a tendency to involve the long tubular bones, and multifocal involvement is common. Here, we present a case of a 69-yr-old man in Shahid Sadooghi Hospital of Yazd in 2014 that had angiosarcoma of the left tibia. He was treated wit...
Between 1965 and 1989, 96 consecutive patients (64 men and 32 women) underwent complete pulmonary resection for metastatic renal cell carcinoma. Median age was 63 years (range, 33 to 82 years). Median time between nephrectomy and pulmonary resection was 3.4 years (range, 0 to 18.4 years). Forty-eight patients had solitary metastasis, 16 had two, 18 had three, and 14 had more than three. Wedge e...
