Solitary splenic metastasis is extremely rare, with only 27 reported cases in the literature. An 81-year-old woman was referred to our hospital for treatment of pulmonary and splenic lesions. Chest computed tomography showed a small lung nodule in the right upper lobe, abdominal computed tomography showed an 8 cm splenic mass with abnormal accumulation, and positron emission tomography revealed a maximum standardized uptake value of 7.9. She had elevated serum cancer antigen 19-9 (1847 U/mL) and carcinoembryonic antigen concentrations (17...

PURPOSE: To evaluate safety and feasibility of transcatheter arterial chemoembolization with superabsorbent polymer microspheres (SAP-MS) for patients with pulmonary or mediastinal metastasis from breast cancer. METHODS: Between November 2002 and January 2015, 14 patients with 29 unresectable pulmonary or mediastinal breast cancer metastases underwent transcatheter arterial chemoembolization using SAP-MS (50-100 μm) after injection of a combination of 2-4 types of anticancer drugs (eg, cisplatin [30 mg] + fluorouracil [500 mg], or epirubicin [40 mg] + mitomycin C [4 mg] + fluorouracil [500 mg])...

In this pilot study, 10 dogs with osteosarcoma (OSA) were treated with amputation and subsequent carboplatin chemotherapy (300 mg/m(2) IV q3wk × 4 doses) followed by toceranib phosphate (2.75 mg/kg PO q48h starting at day 14 post carboplatin). Monthly clinical monitoring and serum measurements of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) were acquired. No dogs were removed from the study due to toxicity. Levels of VEGF and MMP-9 did not change over time. Seven dogs died related to local recurrence and/or pulmonary or bone metastasis and the remainder died of other causes...

Renal cell carcinoma (RCC) is a common malignancy. Metastases can be seen both synchronously, at the time of diagnosis, and metachronously during follow-up. At the time of diagnosis, 23% of the patients have metastatic disease. and 25% of patients will develop metastasis during follow-up period after nephrectomy. Nearly 80% of them develop within the first 5 years. However late metastasis of RCC have been also reported within the postoperative 10 years in the literature. For metastatic lesions, if surgically feasible, metastasectomy, and targeted pharmaceutical agents have been recommended...

Early detection of metastasis can be aided by circulating tumor cells (CTCs), which also show potential to predict early relapse. Due to the limited CTC numbers in peripheral blood in early stages, we investigated CTCs in pulmonary vein blood accessed during surgical resection of tumors. Pulmonary vein (PV) and peripheral vein (Pe) blood specimens from patients with lung cancer were drawn during the perioperative period and assessed for CTC burden using a microfluidic device. From 108 blood samples analyzed from 36 patients, PV had significantly higher number of CTCs compared to pre-operative Pe (p<0...

BACKGROUND ALK gene rearrangements as oncogenic drivers have been described in many cancers, including inflammatory myofibroblastic sarcoma (IMS). The first-generation ALK inhibitor was limited in its ability to cross the blood-brain-barrier to treat brain metastasis. Drug-resistance invariably develops over time in ALK-rearranged tumors, which leads to disease progression. The newer generations of ALK inhibitors are designed to have higher potency in ALK inhibition and improved CNS penetration. CASE REPORT We report a rare case of pulmonary IMS with ALK-1 gene rearrangement and multiple brain metastases as initial presentation...

We present a case of a large thymoma with invasion to the hilum of the lung and pleural dissemination. A 58-year-old woman was diagnosed with a type B2 thymoma, with suspected pericardium, pulmonary artery and left lung invasion and pleural metastasis (Masaoka-Koga stage IVb). A radical resection was planned after systemic chemotherapy. Through a median sternotomy, we resected the tumour, and after confirmation of pericardium and left lung invasion, we also performed resection of the pericardium, of the lung and of the pleural metastasis...

BACKGROUND: Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported. PATIENTS AND METHODS: All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed...

INTRODUCTION: Thyroid metastases from colorectal cancer are uncommon and few cases are described in literature. CASE PRESENTATION: A 64-year-old female patient presented with an asymptomatic right cervical nodule with a rapid growth six years after sigmoidectomy for cancer and two years after resection of colorectal lung metastases. Increased CA 19.9 was identified and a thoracoabdominal CT scan revealed the onset of new metastatic bilateral pulmonary lesions. Neck ultrasonography showed a suspicious nodule in the right thyroid lobe, and Fine-needle Aspiration Cytology (FNAC) of the nodule lead to the diagnosis of colorectal cancer metastasis...

Uropathogenic Escherichia coli (UPEC) is the leading cause of urinary tract infections and plays a role in prostatic carcinogenesis and prostate cancer (PCa) progression. However, the mechanisms through which UPEC promotes PCa development and progression are unclear. Cytotoxic necrotizing factor 1 (CNF1) is one of the most important UPEC toxins and its role in PCa progression has never been studied. We found that UPEC-secreted CNF1 promoted the migration and invasion of PCa cells and PCa metastasis. In vitro studies showed that CNF1 promotes pro-migratory and pro-invasive activity through entering PCa cells and activating Cdc42, which subsequently induced PAK1 phosphorylation and upregulation of MMP-9 expression...

REVIEW
Hasan Fevzi Batirel
Surgical techniques for treatment of malignant pleural mesothelioma (MPM) have improved over the decades. The main surgical principle was accepted as macroscopic complete resection. This principle was achieved with extrapleural pneumonectomy (EPP) and extended pleurectomy/decortication (P/D). Mortality and morbidity are higher following EPP with supraventricular arrhythmias, pulmonary embolism, bronchopleural fistula and pulmonary failure being the most common, while prolonged air leak is frequent following P/D...

Perivascular epithelioid cell tumors (PEComas) are mesenchymal neoplasms with immunoreactivity for both melanocytic and smooth muscle markers. PEComas occur at multiple sites, and malignant PEComas can undergo metastasis, recurrence and aggressive clinical courses. Although the lung is a common metastatic site of PEComas, they usually appear as multiple nodules but rarely become cystic or cavitary. Here, we describe a female patient whose lungs manifested multiple cystic, cavity-like and nodular metastases 3 years after the resection of uterine tumors tentatively diagnosed as epithelioid smooth muscle tumors with uncertain malignant potential...

OBJECTIVE: Current diagnosis of radioactive iodine (RAI)-refractory (RAIR) differentiated thyroid cancer (DTC) is based on the imaging technique, which is of a high cost. Serum thyroglobulin (Tg) is a sensitive and easily obtained biomarker. Hence, we aimed to assess the predicting value of quantitative response of Tg in earlier identifying the RAIR-DTC with pulmonary metastasis. PATIENTS AND METHODS: Pulmonary metastatic DTC patients who underwent total or near-total thyroidectomy and at least two times of RAI therapy were included in this study...

Tenosynovial giant cell tumors (TGCTs) arise from the synovium of joint, bursa, and tendon sheath, and are classified into localized and diffuse types. Diffused type often affects the large joint, and has more recurrence, metastasis, and malignant transformation potential compared to the localized type. Malignant diffused TGCT (D-TGCT) usually occurs as a large tumor (>5 cm), in older patients, and its histopathologic features include necrosis, cellular anaplasia, prominent nucleoli, high nuclear cytoplasmic ratio, brisk mitosis, discohesion of tumor cells, paucity of giant cells, and a diffuse growth pattern...

A 56-years-old woman, who had undergone a complete resection for atypical meningioma (grade 2 of World Health Organization classification)8 years before was admitted to our hospital to treat a mass on the right middle lobe detected by chest X-ray. The mass was resected successfully by video-assisted thoracoscopic surgery and pathological diagnosis of the tumor was a metastatic atypical meningioma. We experienced a rare case of extracranial pulmonary metastasis of meningioma. Grade 2 meningioma is thought to have malignant potential of local recurrence and extracranial metastasis compared to grade 1 meningioma, so long-term observation may be necessary after resection of atypical meningioma...

Osteosarcoma occurs predominantly in children and young adults. High-grade tumors require multidisciplinary treatment consisting of chemotherapy in the neoadjuvant and adjuvant settings, along with surgical intervention. Despite this approach, death from respiratory failure secondary to the development and progression of pulmonary metastases remains a significant problem. Here, we identify the IL-11 receptor α subunit (IL-11Rα) as a cell surface marker of tumor progression that correlates with poor prognosis in patients with osteosarcoma...

The epithelial-to-mesenchymal transition (EMT) in cancer is associated with invasion, metastasis and chemoresistance. Recent studies have revealed the increased expression of programmed death-ligand 1 (PD-L1) in cells undergoing EMT. The underlying mechanism of EMT involves transforming growth factor-β (TGF-β) and fibroblast growth factor-2 (FGF-2). Pirfenidone and the known EMT-suppressor nintedanib suppress pulmonary fibrosis partially through suppression of TGF-β. The present study aimed to determine whether pirfenidone has the potential to induce EMT-reversion, using nintedanib as a reference...
