Polymorphisms in NFKB1 that diminish its expression have been linked to human inflammatory diseases and increased risk for epithelial cancers. The underlying mechanisms are unknown, and the link is perplexing given that NF-κB signaling reportedly typically exerts pro-tumorigenic activity. Here we have shown that NF-κB1 deficiency, even loss of a single allele, resulted in spontaneous invasive gastric cancer (GC) in mice that mirrored the histopathological progression of human intestinal-type gastric adenocarcinoma...

Background : With the integration of various targeted therapies into the clinical management of patients with advanced lung adenocarcinoma, next-generation sequencing (NGS) has become the technology of choice and has led to an increase in simultaneously interrogated genes. However, the broader adoption of NGS for routine clinical practice is still hampered by sophisticated workflows, complex bioinformatics analysis and medical interpretation. Therefore, the performance of the novel QIAGEN GeneReader NGS system was compared to an in-house ISO-15189 certified Ion PGM NGS platform...

Afatinib exhibits therapeutic efficacy for lung adenocarcinoma patients harboring HER2 exon 20 insertions. HER2 S310Y single site substitution was discovered in recent years and afatinib efficacy for adenocarcinoma patients harboring S310Y mutation has not been reported. We presented a case of a 41-year-old male patient with lung adenocarcinoma harboring the HER2 S310Y mutation obtained clinical response to the treatment of afatinib, an oral HER family blocker. After the treatment of afatinib, the patient achieved partial response (PR) in chest lesions and almost complete response (CR) in intracranial lesions...

A 25-year-old man with IgA deficiency was treated with 2 months of chemotherapy and proton therapy for gastroesophageal junction adenocarcinoma. Restaging PET/CT 18 days posttherapy demonstrated 2 new foci of increased FDG uptake in the left hepatic lobe, which were favored to represent radiation injury as opposed to new metastases. Follow-up MRI with contrast 2 weeks later demonstrated hypoenhancement and T1/T2 hypointensity in the liver, without restricted diffusion, which correlated with the dominant FDG-avid focus...

RATIONALE: The small intestine (SI) does not commonly harbor cancer but is occasionally involved by metastatic cancer from other organs. To manage SI cancer appropriately, surveillance for primary origin outside the SI is essential. PATIENT CONCERNS: This study presents a 54-year-old Thai man diagnosed with SI obstruction which required laparoscopy- assisted partial ileal resection. DIAGNOSES: On the basis of the expression pattern of cytokeratins (CKs) and mucins (MUCs) in the resected SI adenocarcinoma, we suspected this was metastasized from the pancreatobiliary tract...

OBJECTIVES: Adenosquamous cancer of pancreas (ASCP) is a rare variant of pancreatic adenocarcinoma (PDAC). It is characterized by poor prognosis and lacks of literature data supporting the choice of systemic therapies. The role of immunotherapy for this malignancy is still unknown. In this study, we evaluated any differences between immune-related genes of PDAC and its adenosquamous variant with the aim to characterize these histothistotypes and eventually identify potential biomarkers useful for an immune-therapy approach in ASCP...

We report an unusual case of hamartomatous polyposis with malignant complications in a patient with ulcerative colitis on golimumab and previous thiopurine therapy. This patient was evaluated for iron deficiency anemia and underwent hemicolectomy for extensive right-side predominant inflammatory pseudopolyps. Anemia persisted post-colectomy and subsequent gastroscopy showed a fungating polypoid lesion along with numerous carpet-like strawberry appearing polyps in the stomach extending from the gastro-esophageal junction to the distal part of the antrum, necessitating a gastrectomy...

Necrotizing fasciitis (NF) is a rare entity with its subacute form being even rarer. The condition has also been described to occur in the peristomal area in relation to different clinical scenarios. However, it has not been described in the setting of adjuvant chemotherapy where these medications have already been given. While the diagnosis may be delayed or missed due to the subtle symptomatology of the indolent subacute form of NF, another reason for a delayed or missed diagnosis may be the excessive use of tape and the stoma belt around the stomal appliance to prolong the life of the appliance beyond its recommended days of usage due to economic constraints...

To investigate the prognostic impact of MET copy number ( MET -CN) in patients with non-small cell lung cancer (NSCLC), we retrospectively reviewed clinical and pathologic data of NSCLC patients whose tumors were assessed for MET -CN using fluorescence in situ hybridization (FISH). We correlated MET -CN status with patient overall survival (OS) and optimized MET -FISH reporting criteria. The study group included 384 patients with NSCLC of which 88% were adenocarcinoma and 55.7% of patients had distant metastases...

Non-small cell lung cancer (NSCLC), including adenocarcinoma and squamous cell carcinoma, is the leading cause of death from lung malignancies and has a poor prognosis due to metastasis. Suppressor of cytokine signalling-2 (SOCS2), a feedback inhibitor of cytokine signalling, has been shown to be involved in growth control. Here, we show that SOCS2 were significantly downregulated in tumour foci in NSCLC patients. The expression levels of SOCS2 significantly correlated with clinical stage, lymph node metastasis, histological subtype and survival time...

PURPOSE: Small cell carcinoma of the prostate (SCCP) is an aggressive disease that can arise de novo or by transdifferentiation from prostate adenocarcinoma. Alterations in anaplastic lymphoma kinase (ALK) gene are involved in neuroblastoma, lung cancer, and other malignancies but its role in SCCP has not been documented. We describe a patient with refractory de novo SCCP with ALK F1174C activating mutation who obtained clinical benefit from treatment with ALK inhibitor. EXPERIMENTAL DESIGN: Next-generation sequencing (NGS) was used to analyze primary and circulating tumor DNA (ctDNA)...

BACKGROUND & AIMS: The prognosis for most patients with esophageal adenocarcinoma (EAC) is poor because they present with advanced disease. Models developed to identify patients at risk for EAC and increase early detection have been developed based on data from case-control studies. We analyzed data from a prospective study to identify factors available to clinicians that identify individuals with a high absolute risk of EAC. METHODS: We collected data from 355,034 individuals (all older than 50 years) without a prior history of cancer enrolled in the United Kingdom Biobank prospective cohort study from 2006 through 2010; clinical data were collected through September 2014...
