Pulmonary metastasis

Byung-Rae Cho, Wan-Soo Yoon
The most common intracranial tumour is meningioma, which rarely presents with extracranial metastasis, especially in benign cases. We report a case of meningioma recurrence with multiple pulmonary metastases in a patient who had a benign meningioma removed 12 years prior.

The transcription factor KLF6 has an essential role in the development and metastasis of multiple human cancers. Paradoxically, KLF6 expression was found to be attenuated in primary metastatic clear cell renal cell carcinoma (ccRCC), such that it is unclear how KLF6 affects malignant progression in this setting. In this study, we demonstrate that KLF6 attenuation in renal cells is sufficient to promote E2F1-mediated epithelial-mesenchymal transition and metastatic prowess. In a mouse xenograft model of human ccRCC, silencing KLF6 increased tumor cell proliferation and malignant character, whereas E2F1 silencing reversed these properties...

Carthamus tinctorius L. is a traditional Chinese medicine that activates blood circulation and dissipates blood stasis, and has been extensively used as antitumor treatment in a clinical setting in single or in compound preparation form. However, empirical evidence and a better understanding of the possible mechanisms involved are still required. Here, we investigated the role of safflower yellow (SY), the active ingredient of C. tinctorius, in the pulmonary metastasis of breast cancer, and the underlying mechanism of action...

Cardiac mass can be described as an abnormal structure within or directly contiguous to the heart. Tumors and thrombi are the most common types of cardiac masses. Intracardiac thrombi have been encountered in various clinical settings and can result in severe morbidity and mortality due to embolic events. Cardiac neoplasms are extremely rare, and are usually metastatic tumors. The major primary malignancies associated with cardiac metastases include cancers of the lung, breast, stomach, and liver, and lymphoma, leukemia, and melanoma...

OBJECTIVES: Although wedge resection is the most common surgical procedure for pulmonary metastases from colorectal cancer, there are few reports about segmentectomy for colorectal metastasectomy. METHODS: This was a subset analysis of a Japanese nationwide retrospective study of resected pulmonary metastases from colorectal cancer. The study included 553 patients who underwent segmentectomies (n = 98) or wedge resections (n = 455) without preoperative chemotherapy between January 2004 and December 2008...

INTRODUCTION: Indications and surgical techniques for pulmonary metastasectomy (PME) are controversially discussed issues. Laser-assisted surgery (LAS) is a recent innovation that has been advocated especially in patients with multiple pulmonary metastases (PM). However, there are hardly any studies comparing surgical outcomes after laser-assisted and conventional resection. The aim of the current study was to evaluate the value of LAS in a larger study population. MATERIALS & METHODS: A retrospective analysis was completed on 178 consecutive patients undergoing 236 PMEs at a single center between 2010 and 2015...

BACKGROUND: Because one of the major sites for metastasis of thyroid cancers is the lung, studying the pattern of pulmonary metastasis may provide useful information for the effective treatment of these patients. In this study, by assessing the metastasis pattern, we aimed to identify the factors that may affect prognosis and response to treatment in patients with differentiated thyroid carcinoma (DTC) with pulmonary metastasis. METHODS: This retrospective study included 75 patients with DTC with pulmonary metastasis who were referred to our nuclear medicine section over a period of 10 years...

With the aim of up-regulating antitumor efficacy and down-regulating adverse effects, the amino group in the 3-positon of amonafide aromatic ring was modified by coupling with different amine/polyamine motifs via two linkers. Two series of naphthalimide derivatives were designed and synthesized and evaluated for their antitumor properties in vitro and in vivo. The preliminary in vitro trials revealed that compounds with urea as the linker were not active, and the presence of aspirin elevated the potency of 6k against tumor cells, wound healing and the protein expression of Cyclic D1 and MMP9...

PURPOSE: Sarcoidosis is a granulomatous disease of unknown etiology. Occasionally, triggering causes are identified, such as neoplasms, and they are termed sarcoid-like reactions, which may appear in any sarcoidotic target tissue. Choroidal metastases appear as part of widespread metastatic disease or as the first suggestion of neoplastic disease. They can also be a part of the differential diagnosis of a spectrum of inflammatory eye diseases. We present a case in which a lung carcinoma, pulmonary and eye sarcoid-like reactions, and choroidal metastasis take place in the same patient...

A 67-year-old man presented at our hospital with severe edema on the left side of his neck, chest and brachial regions. He had a history of right radical nephrectomy due to renal cell carcinoma (RCC, clear cell subtype, stage II) 15 years earlier. Thereafter, metastases to the pancreatic tail and right lung, and left lung metastasis were removed at 8 years and 11 years, respectively, after the nephrectomy. Four years earlier, he had also undergone total gastrectomy for gastric carcinoma (poorly differentiated adenocarcinoma, stage IV) and subsequent maintenance chemotherapy for gastric carcinoma...

Sarcoidosis is a multi-system inflammatory disorder of unknown etiology that is manifested by the presence of non-caseating granulomas. Multiple pulmonary nodules are rare presentations of sarcoidosis. We report a case of nodular sarcoidosis in a young male of Middle-East origin who had initially presented with bilateral painful ankle edema. His chest X-ray showed multiple bilateral pulmonary nodules. A high resolution computed tomography scan of the chest demonstrated multiple pulmonary nodular lesions and also mediastinal and hilar lymphadenopathy...

Pulmonary adenocarcinoma with enteric differentiation (PAED) is a rare subtype of lung adenocarcinoma recently recognized in the WHO classification. It is defined as an adenocarcinoma in which the enteric component exceeds 50% and have to show the expression of at least 1 immunohistochemical marker of enteric differentiation. Although the definition of this tumor type is very important, above all in the differential diagnosis between a primary lung tumor and a metastasis of colorectal adenocarcinoma, this cancer still lacks a distinctive immunohistochemical and molecular signature...

OBJECTIVE: The purpose of the present study was to investigate the predictive factors for worse disease-specific survival in patients with pulmonary disease secondary to differentiated thyroid cancer. METHODS: This was a retrospective cohort study conducted over a 5-year period that included 54 patients with pulmonary disease secondary to DTC during the follow-up. Among these patients, 13 (24.1%) died from the disease. Dedifferentiation characteristics were identified at pathological examination of the metastatic disease (lymph node or distant metastases), and was defined as the abrupt transformation of a well-differentiated tumor into high grade morphology that lacks the original distinct histologic characteristics...

In January 2003, a 55-year old, non-smoking woman visited our hospital to undergo treatment for T4N0M0 pulmonary adenocarcinoma of the left lung. Until death in October 2015, she received over 20 lines of treatment including a second line therapy with gefitinib, which showed long response. In March 2014, she noticed the left axillar lymph node swelling. Aspiration cytology of the lymph node revealed the presence of adenocarcinoma harboring EGFR exon 19 deletion (Ex19del) but not T790M. Concomitant ALK translocation of variant 1 was also detected...

Primary pulmonary chondrosarcoma is a rare neoplasm that usually grows slowly, metastasizes late, and responds well to excision when localized. Herein, we present a 59-year-old man who manifested with hemoptysis, cough and dyspnea with a hemithorax mass. A chest computed tomography scan demonstrated a fast-growing mass in the right upper lobe, and the enhancement was partially heterogeneous. Bronchoscopy revealed a hemorrhagic neoplasm in the right upper bronchus. A bronchoscopy biopsy specimen revealed a variety of tissues, including mucoid cartilage, fibers, respiratory epithelium and squamous epithelium...
