Several strategies to improve the efficacy of radiation therapy against hepatocellular carcinoma (HCC) have been investigated. One approach was to develop radiosensitizing compounds. Because histone deacetylase 4 (HDAC4) is highly expressed in liver cancer and known to regulate oncogenesis through chromatin structure remodeling and controlling protein access to DNA, we postulated that HDAC4 inhibition might enhance radiation's effect on HCC cells. HCC cell lines (Huh7 and PLC5) and an ectopic xenograft were pretreated with HDAC inhibitor or shRNA to knock down expression of HDAC4, and then irradiated (2...

PURPOSE: Hepatic arterial infusion chemotherapy (HAIC) is an option for patients with liver-predominant metastatic breast cancer (LMBC), when no further systemic treatment is available. But systematic reports are limited. Here we conducted a retrospective analysis of LMBC patients treated at an expert center. METHODS: Individual patient data were retrieved from the clinical data base of the West German Cancer Center. Primary endpoints included hepatic response (RECIST), progression-free survival (PFS), overall survival (OS), and toxicity...

It has been reported that long non-coding RNA PANDA was disregulated in varieties types of tumor, but its expression level and biological role in hepatocellular carcinoma (HCC) remains contradictory. We detected PANDA expression in two independent cohorts (48 HCC patients following liver transplantation and 84 HCC patients following liver resection), and found that PANDA was down-regulated in HCC. Thereafter we explored its function in cancer biology by inversing its low expression. Surprisingly, overexpression of PANDA promoted HCC proliferation and carcinogenesis in vitro and in vivo...

Cyclin-dependent kinase 9 (CDK9), a subunit of the positive transcription elongation factor b (P-TEFb) complex, regulates gene transcription elongation by phosphorylating the carboxy-terminal domain (CTD) of RNA polymerase II (RNAPII).  The deregulation of CDK9/P-TEFb has important implications for many cancer types.  BAY 1143572 is a novel and highly selective CDK9/P-TEFb inhibitor currently being investigated in phase I studies. We evaluated the therapeutic potential of BAY 1143572 in adult T-cell leukemia/lymphoma (ATL)...

OBJECTIVE: Liver cancer is a growing global public health problem. Ultrasonography is an imaging tool widely used for the early diagnosis of liver cancer. However, the effect of ultrasonography surveillance (US) on the survival of patients with liver cancer is unknown. Therefore, this study examined the association between survival and US frequency during the 2 years preceding patients' liver cancer diagnosis. METHODS: This population-based longitudinal study was conducted in Taiwan, a region with high liver cancer incidence, by using the National Health Insurance Research Database...

Hepatitis B virus (HBV) is the smallest partially double-stranded DNA virus known to infect humans. Worldwide, more than 50% of hepatocellular carcinoma (HCC) cases are related to chronic Hepatitis B. Development of HCC from normal liver cells is characterized by changes in cell surface N-glycans, which can promote the invasive behavior of tumor cells, leading ultimately to the progression of cancer. However, little is understood about the cell surface N-glycans of HBV-infected liver cells. We try to address this by taking advantage of the HepAD38 cell line, which can replicate HBV in the absence of tetracycline [tet(-)] in growth medium...

Accumulating evidence has revealed the importance of cancer stem cells (CSCs) in chemoresistance and recurrence. BORIS, a testes-specific CTCF paralog, has been shown to be associated with stemness traits of embryonic cancer cells and epithelial CSCs. We previously reported that BORIS is correlated with the expression of the CSC marker CD90 in hepatocellular carcinoma (HCC). These results encourage us to wonder whether BORIS exerts functions on CSC-like traits of human liver cancer cells. Here, we report that BORIS was enriched in HCC tissues...

A 57-year-old man presented to the surgical oncology clinic with a mildly tender mass under his right arm. Four years prior, the patient had a melanoma removed from his right shoulder along with an ipsilateral right axillary sentinel lymph sampling. Computed tomography (CT) scan was negative for metastatic disease at that time. The patient did not undergo completion axillary node dissection and was lost to follow-up. The patient was originally from Australia, did not tan but reported multiple sunburns before age 18...

We explored the association between single nucleotide polymorphisms (SNPs) in ACYP2 and liver cancer risk. Thirteen SNPs were genotyped in 473 cases and 564 controls. Genetic model, linkage disequilibrium, and haplotype analyses were performed to evaluate the association between ACPY2 SNPs and liver cancer risk. We found that rs6713088 (G allele: odds ratio [OR] = 1.27, 95% confidence interval [CI]: 1.07-1.52, P = 0.007; GG vs. CC: OR = 1.49, 95% CI: 1.02-2.1, P = 0.038), rs843711 (T allele: OR = 1.29, 95% CI: 1...

Although many studies have discussed the association of abnormally expressed silent information regulator 1 (Sirt1) with the prognosis of patients with a variety of solid carcinomas, they failed to agree on whether excessive Sirt1 indicates a good or poor overall survival for the patients. We conducted the current meta-analysis to illustrate the prognostic value of Sirt1 in solid malignancies. Articles published before December 2016 were searched using Pubmed and Web of Science. The studies were selected for the meta-analysis based on certain criteria...

Hepatocellular carcinoma (HCC) management has evolved in the last decades. Current available treatments include interventional radiology like radiofrequency ablation, transarterial chemoembolization or Yttrium 90 radioembolization. Surgery, when possible, has been proven to be the most effective treatment in reducing the risk of long-term local recurrence. American and European societies (AASLD, EASL, respectively) guidelines for the management of HCC endorse The Barcelona Clinic Liver Cancer (BCLC) treatment allocation system...

Qi Zhang, Gaojun Teng
Colorectal liver metastasis (CRLM) is one of the most difficult and key points in the treatment of colorectal cancer. Approximately 50% to 60% of patients diagnosed as colorectal cancer develops metastasis, and 80% to 90% of CRLM is unresectable. Surgical resection is the first-line treatment for CRLM, while it is only suitable for about 15% patients. Systemic chemotherapy can prolong the survival of CRLM patients, however, a part of CRLM patients are resistant to chemotherapy. With the development of technology and the update of clinical evidence, individual therapy with target drugs and multidisciplinary treatment (MDT) have became a tendency, and minimally invasive interventional therapy has gained more acceptance in the MDT mode of the treatment for CRLM...

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision...

Despite a significant increase of bloodstream infection caused by extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae in the community-setting, information regarding clinical outcomes of inappropriate empiric therapy (IAT) in patients with those infections is limited. A multicenter-retrospective cohort study was conducted in four hospitals. A total of 249 adults were identified to have community-onset bacteremia caused by ESBL-producing Escherichia coli and Klebsiella pneumoniae, and definitively treated with carbapenems...

Metastatic esophageal adenocarcinoma to the urinary bladder is extremely rare. We describe a previously healthy 49-year-old female with recent diagnosis of adenocarcinoma of the gastroesophageal junction with metastatic disease to the liver. Biopsy was positive for human epidermal growth factor receptor 2 (HER2) by Fluorescence In Situ Hybridization (FISH). She received six cycles of Cisplatin, 5-Fluorouracil, and Herceptin and subsequently developed symptomatic anemia and hematuria. Cystoscopy with retroflexion was performed and she received a transurethral resection of bladder tumor with fulguration...

Liver receptor homolog-1 (LRH-1) is an orphan nuclear receptor that is critical for the growth and proliferation of cancer cells and other biological processes, including lipid transportation and metabolism, sexual determination and steroidogenesis. However, because homozygous lrh-1(-/-) mice die in utero, the regulatory mechanisms involved in embryonic development mediated by this receptor are poorly understood. In the present study, we performed transcription activator-like effector nuclease (TALEN)-mediated loss-of-function assays, taking advantage of zebrafish external fertilization, to investigate the function of lrh-1...
