BACKGROUND: Following chemo-radiotherapy (CCRT) for human papilloma virus positive (HPV+) locally advanced head and neck cancer, patients frequently undergo unnecessary neck dissection (ND) and/or repeated biopsies for abnormal PET-CT, which causes significant morbidity. We assessed the role of circulating HPV DNA in identifying 'true' residual disease. METHODS: We prospectively recruited test (n=55) and validation (n=33) cohorts. HPV status was confirmed by E7 RT-PCR...

Resection is the gold standard in the treatment of liver metastases from colorectal cancer. An internal cooled radiofrequency electrode was described to achieve tissue coagulation to a greater margin width. The aim of this study is to determinate if a RF-assisted transection device (RFAT) has any effect on local hepatic recurrence (LHER) compared to conventional technologies. A study population of 103 patients who had undergone a hepatic surgical resection was retrospectively analysed. Patients were classified into two groups according to the device used: a RF-assisted device (RFAT group; n = 45) and standard conventional devices (control group; n = 58)...

Hepatitis B virus (HBV) is a major cause of hepatocellular carcinoma (HCC). However, very little is known about the replication of HBV in HCC tissues. PATIENTS AND METHODS: We analysed viral and cellular parameters in HCC (T) and non-tumor liver (NT) samples from 99 HBsAg-positive, virologically suppressed patients treated by tumour resection or liver transplantation. We examined total HBV DNA and RNA as well as covalently closed circular DNA (cccDNA) and pregenomic RNA (pgRNA), which are considered as markers of active HBV replication...

Renal cell carcinoma accounts for 3% of all adult malignancies. Usual sites of metastasis are lymph nodes, lungs, bone, liver and brain. We describe a patient who presented with complaints of holocranial headache and diplopia. MRI of the head showed a clival-based lesion with associated bony erosion. With suspicion of a metastatic lesion, an ultrasonogram of the abdomen was done which showed a left renal mass that enhanced on contrast-enhanced CT. There were no other metastatic foci. Patient underwent radiotherapy for the clival lesion...

A ten-year-old male neutered cross breed dog presented for evaluation of a mass associated with the left scapular bone, identified as a carcinoma. The dog had a malignant pilomatricoma removed from the left lateral thigh 6 months earlier. Histopathology review of the cutaneous and scapular mass identified the same tumour type, confirming metastatic disease; additional metastases to the inguinal lymph node, liver and lungs were identified. Chemotherapy resulted in partial responses/stable disease of very short duration...

BACKGROUND: Laparoscopic liver surgery is seldom performed, mainly because of the risk of hepatic vein bleeding or incomplete resection of the tumour. This risk may be reduced by means of an augmented reality guidance system (ARGS), which have the potential to aid one in finding the position of intrahepatic tumours and hepatic veins and thus in facilitating the oncological resection and in limiting the risk of operative bleeding. METHODS: We report the case of an 81-year-old man who was diagnosed with a hepatocellular carcinoma after an intraabdominal bleeding...

Caffeic acid phenethyl ester (CAPE), extracted from propolis, was proven to inhibit colon cancer. Caffeic acid p-nitro-phenethyl ester (CAPE-pNO2), a derivative of CAPE, was determined to be an anti-platelet agent and a protector of myocardial ischaemia with more potent effects. In the present study, CAPE-pNO2 showed stronger cytotoxic activity than CAPE. We revealed interactions between CAPE-pNO2 and experimental cells. CAPE-pNO2 induced apoptosis in HT-29 cells by up-regulating P53, cleaved-caspase-3, Bax, P38 and CytoC; CAPE-pNO2 also up-regulated P21(Cip1) and P27(Kip1) and down-regulated CDK2 and c-Myc to promote cell cycle arrest in G0/G1...

Colonic inflammation seen in inflammatory bowel disease (IBD) predisposes to the development of colorectal adenocarcinoma. In contrast, colorectal neuroendocrine carcinomas (NECs) have rarely been reported in the setting of IBD, and no definitive relationship between these tumours and IBD has been established. Dysplasia from chronic inflammation leading to neuroendocrine cell differentiation may be responsible for NEC development, though this finding has not been seen consistently. We present a case of large-cell neuroendocrine carcinoma of the sigmoid colon in a 65-year-old woman with long-standing ulcerative colitis...

BACKGROUND: Data suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resin microspheres in patients with metastatic colorectal cancer with liver metastases. The studies were designed for combined analysis of overall survival...

Most hepatocellular carcinomas (HCCs) develop as a result of chronic liver inflammation. We have shown that the oncoprotein gankyrin is critical for inflammation-induced tumourigenesis in the colon. Although the in vitro function of gankyrin is well known, its role in vivo remains to be elucidated. We investigated the effect of gankyrin in tumour microenvironment of mice with liver parenchymal cell-specific gankyrin ablation (Alb-Cre;gankyrin(f/f) ) and gankyrin deletion both in liver parenchymal and non-parenchymal cells (Mx1-Cre;gankyrin(f/f) )...

From the last few years, hepatitis C virus and the new direct antiviral treatments are being more and more important. In consequence, case studies like the one we present, the appearance of hepatocelullar carcinoma after its eradication with fibrosis grade 2, are getting special interest. In 2007, our patient was treated with pegylated interferon α-2a and ribavirin, having a sustained virological response after it. In this way, liver fibrosis grade 2 was confirmed by a biopsy. Finally, after corroborating a good liver functioning, the patient was discharged (as, according to the guidebooks, an ultrasound scan of screeing every 6 months was not required)...

Hypoxia-inducible factors (HIFs) play a central role in the transcriptional response to changes in oxygen availability. Stability of HIFs is regulated by multi-step reactions including recognition by the von Hippel-Lindau tumour suppressor protein (pVHL) in association with an E3 ligase complex. Here we show that pVHL physically interacts with fatty acid synthase (FASN), displacing the E3 ubiquitin ligase complex. This results in HIF-α protein stabilization and activation of HIF target genes even in normoxia such as during adipocyte differentiation...

Hepatocellular carcinoma (HCC) is the most common of all liver cancers and is a major worldwide public health problem. The aim of this study was to provide an updated overview on clinicopathological features, treatment and outcome of HCC. In our retrospective study, we reviewed 64 cases of HCC that were diagnosed at the pathology department of Mongi Slim hospital over a fifteen-year period (2000- 2014). Relevant clinical information and microscopic slides were retrospectively reviewed. Our study group included 38 men and 26 women (sex ratio M/F = 1,26) aged between 8 and 83 years (mean = 56,64 years)...

REVIEW

BACKGROUND: Liver transplantation (LT) is the only cure for patients diagnosed with unresectable hepatocellular carcinoma (HCC), and HCC has become the leading indication for LT in the USA. The shortage of liver grafts results in a significant waiting time for LT with the risk of tumour progression. Treating HCCs during the waiting time prior to transplantation (bridging therapy) is an attractive strategy to reduce the risk of exceeding the tumour criteria for transplantation. Studies on bridging therapy are heterogenous and due to ethical issues, mostly of retrospective design...
