Thymic carcinoma is a rare cancer, accounting for only 1% to 4% of thymic epithelial tumors. Endobronchial metastasis is a rare presentation of these tumors. A 64-year-old man presented with a cough. Lung cancer was suspected because a chest radiograph showed a 7-cm mass in the left pulmonary hilum. Computed tomography showed a mass in the anterior mediastinum and an infiltrate in the upper lobe of the left lung. Bronchoscopy demonstrated bilateral polypoid tumors in the left B bronchus and the right B bronchus...

The ability to monitor tumor motion without implanted markers can potentially enable broad access to more accurate and precise lung radiotherapy. A major challenge is that kilovoltage (kV) imaging based methods are rarely able to continuously track the tumor due to the inferior tumor visibility on 2D kV images. Another challenge is the estimation of 3D tumor position based on only 2D imaging information. The aim of this work is to address both challenges by proposing a Bayesian approach for markerless tumor tracking for the first time...

OBJECTIVES: Helicobacter pylori is associated with peptic ulcers and gastric cancer and its eradication aims to prevent these conditions. The recommended eradication regimen is triple therapy, consisting of a proton-pump inhibitor in combination with clarithromycin and amoxicillin or metronidazole for 7 days. Yet, other antibiotic regimens are sometimes prescribed. We aimed to assess the use of eradication therapy for H. pylori in the Swedish population during the last decade. MATERIALS AND METHODS: This population-based study used data from the Swedish Prescribed Drug Register...

Ewing Sarcoma is the second most common solid pediatric malignant neoplasm of bone and soft tissue. Driven by EWS/Ets, or rarely variant, oncogenic fusions, Ewing Sarcoma is a biologically and clinically aggressive disease with a high propensity for metastasis. However, the mechanisms underpinning Ewing Sarcoma metastasis are currently not well understood. In the present study, we identify and characterize a novel metastasis-promotional pathway in Ewing Sarcoma, involving the histone demethylase KDM3A, previously identified by our laboratory as a new cancer-promoting gene in this disease...

ROS1 and ALK are promising targets of anti-cancer drugs for non small cell lung cancer. Since they have 49% amide acid sequence homology in the kinases domain and 77% identity at the ATP binding area, some ALK inhibitors also showed some significant responses for ROS1 in the clinical trial, such as the type-I binding inhibitor crizotinib and PF-06463922. As a newly therapeutic target, selective ROS1 inhibitor is relative rarely. Moreover, the molecular basis for the selectivity of ROS1 versus ALK still remains unclear...

BACKGROUND: Blood diseases and cancer are part of a group of rare conditions in pediatrics. In general, cancer treatments are prolonged (months or years), so psychosocial support has been introduced to provide comprehensive care to these patients. OBJECTIVE: To explore psychosocial care provided at the public hospitals of Argentina to children and adolescents with cancer. Population and Methods. An electronic questionnaire was sent to the heads of the Departments of Hematology and Oncology, Mental Health, and Social Services of 27 public hospitals providing care to pediatric patients with cancer...

Lactic acidosis is a potentially life-threatening complication characterized by accumulation of blood lactate resulting in low arterial pH. The majority of lactic acidosis in malignancies are reported in association with hematologic malignancies. It may result from an imbalance between lactate production and hepatic lactate utilization, but the exact pathophysiology is far more complex than what we can fathom from current micromolecular studies. We report a case of a 71-year-old male with metastatic lung cancer presenting with fatal lactic acidosis in the absence of liver involvement...

BACKGROUND: Hepatocellular adenoma is a benign liver tumour that may transform to hepatocellular carcinoma (HCC). We used data from Danish nationwide healthcare registries to investigate the incidence and prognosis of hepatocellular adenoma. METHODS: We included all patients with a hospital discharge diagnosis for benign liver tumour (ICD-10: D13.4) in 1997-2012 and a liver biopsy confirming the hepatocellular adenoma diagnosis. Follow-up began one year after adenoma diagnosis, to minimize the possibility that the tumour was a misdiagnosed HCC...

The biliary duct is an extremely rare site for colon cancer metastasis. It often leads to a diagnostic dilemma, since primary cholangiocarcinoma (potentially treatable with surgery) has a similar presentation. This paper highlights our experience with 5 consecutive patients who had colon malignancy with biliary metastasis, and prognosis of their disease. Five patients, with a history of primary colon cancer since 2010, were identified to have biliary metastasis. Of these, 4 (80.0%) patients were male. The median time to diagnosis of biliary metastasis from diagnosis of colon cancer was 59...

The Fibrolamellar variant of Hepatocellular Carcinoma (FLHCC) is a rare form of liver cancer that presents in the 3(rd) decade of life, is rarely associated with cirrhosis or chronic Hepatitis B/C virus infection, and usually presents with normal serum alpha-fetoprotein (AFP) levels. FLHCC presenting during pregnancy is extremely rare, with only 4 cases reported. We present a case of FLHCC in pregnancy and discuss the dilemmas in management. A 26 year-old primigravida, 26 weeks of gestation presented with a month's history of obstructive jaundice secondary...

BACKGROUND: Death-associated protein kinase 1 (DAPK) is an important tumor suppressor kinase involved in the regulation of multiple cellular activities such as apoptosis and autophagy. DNA methylation of DAPK gene was found in various types of cancers and often correlated with the clinicopathological characteristics. However, the mRNA and protein expression of DAPK in the same sample was rarely measured. Thus, it was unclear if the correlation between DAPK gene methylation and clinicopathological parameters was due to the loss of DAPK expression...

PURPOSE: The effect of pre-operative MRI on the in-breast tumor recurrence rate (IBTR) of patients undergoing breast-conservation treatment (BCT) remains uncertain. We began to routinely perform pre-operative MRI in 2006. Our goal was to determine the effect of pre-operative MRI on IBTR. METHODS: Retrospective review of a prospective database of all patients undergoing BCT (n = 1396) from 2000 to 2010. IBTR were calculated using Kaplan-Meier estimates. RESULTS: 664 (47...

Primitive neuroectodermal tumour (PNET) of kidney is a rare cancer typical of young adults with few cases described in the literature. We report a case of renal PNET in a 31-year-old man who presented to our department with a computed tomographic (CT)-scan revealing a large renal mass of 20 cm, massive thrombosis of the inferior vena cava (IVC). The patient underwent radical nephrectomy with contextual retroperitoneal lymphadenectomy and resection of IVC needing Dacron prosthesis substitution. Definitive histopathological examination showed PNET of kidney infiltrating ipsilateral adrenal gland, massive cava thrombosis with infiltration of vena cava wall and one lymph nodal metastasis...

Xp11 translocation renal cell carcinoma (RCC) with SFPQ/PSF-TFE3 gene fusion is a rare epithelial tumor. Of note, the appearance of the gene fusion does not necessarily mean that it is renal cell carcinoma. The corresponding mesenchymal neoplasms, including Xp11 neoplasm with melanocytic differentiation, TFE3 rearrangement-associated perivascular epithelioid cell tumor (PEComa) and melanotic Xp11 translocation renal cancer, can also harbor the identical gene fusion. However, the differences between Xp11 translocation RCC and the corresponding mesenchymal neoplasm have only recently been described...

Medullary thyroid carcinoma (MTC) is an aggressive and rare cancer with limited treatment options for metastatic disease. Due to this, there is a need for a better understanding of MTC biology in the hope of improved treatments. One area of improved understanding of cancer biology is epigenetics. Epigenetics is defined as cellular processes which alter gene expression independent of changes in the primary DNA sequence. These processes include modifications such as DNA methylation, microRNA deregulation and post-translational histone modifications, all of which have been implicated in tumorigenesis of MTC...

REVIEW
Alfred King-Yin Lam, Nassim Saremi
The aim of this systematic review is to study the features of cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) by analysing the 129 documented cases in the English literature. The disease occurred almost exclusively in women. The median age of presentation for CMV-PTC was 24 years. Slightly over half of the patients with CMV-PTC had familial adenomatous polyposis (FAP). CMV-PTC presented before the colonic manifestations in approximately half of the patients with FAP. Patients with FAP often have multifocal tumours in the thyroid...
