Germline mutations of the DNA repair pathways in uterine serous carcinoma.

Mon, 28 Mar 2016 20:57:02 +0100

CONCLUSIONS: A significant proportion of our cohort harbor germline mutations in DNA repair genes. This may be associated with the high rate of breast cancer in our patients and their family, and suggests a targeted cohort for genetic counseling. If validated in a larger cohort, our findings may allow clinicians to expand therapeutic options to include targeted therapies and inclusion of USC patient in preventative and genetic counseling.

Mp39-19 prostate cancer detection with digital rectal exam in the prostate lung colorectal and ovarian (plco) cancer screening trial

Mon, 28 Mar 2016 19:24:11 +0100

There has been great controversy regarding prostate cancer screening with prostate specific antigen (PSA) due to conflicting results from two large randomized trials. However, the contemporary role of digital rectal exam (DRE) for screening has been largely overlooked. This is particularly salient given the recent decline in PSA and possibly overall prostate cancer screening. We sought to evaluate the prognostic significance of suspicious DRE in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Trial in which men were randomized to annual screening with PSA and DRE or usual care.

Mon, 28 Mar 2016 19:24:05 +0100

Though the digital rectal exam (DRE) is a key component of prostate cancer screening, its utility in the workup of lower urinary tract symptoms is poorly understood. Nocturia is among the most bothersome lower urinary tract symptoms, and its multifactorial etiology requires broad clinical evaluation. Using data from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, this study aims to assess the accuracy and reliability of DRE in estimating prostate size, and to correlate these findings with the presence of nocturia (Source: The Journal of Urology)

Mp08-01 perioperative blood transfusion and radical prostatectomy: analysis of the national surgical quality improvement program database

Mon, 28 Mar 2016 19:24:03 +0100

Radical prostatectomy remains a mainstay in the treatment of clinically significant localized prostate cancer. The literature suggest that perioperative blood transfusion (PBT) in oncologic surgeries may lead to poorer long-term outcomes of recurrence, progression, and survival, for colon, pancreatic, esophageal and gynecologic malignancies. Previous studies have not shown this to be true for prostatectomy but there has yet to be a study examing the impact of PBT on 30-day post-operative outcomes. (Source: The Journal of Urology)

S&t-50 does transperineal prostate biopsy reduce complications compared with transrectal biopsy? a systematic review and meta-analysis of randomised controlled trials

Mon, 28 Mar 2016 19:24:00 +0100

The detection of prostate cancer relies in part upon the two established techniques of transperineal (TP) and transrectal (TR) prostate biopsy. The more commonly used TR biopsy is associated with higher rates of infective complications, as it traverses the rectum. This systematic review and meta-analysis aims to determine if any difference in complication rate exists between TR and TP prostate biopsy. (Source: The Journal of Urology)



Pi-lba02 reevaluating psa testing rates in the plco trial

Mon, 28 Mar 2016 19:23:59 +0100

Much of the controversy surrounding prostate specific antigen (PSA) screening revolves around the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial. The PLCO trial randomized men to annual prostate cancer screening or usual care and found equivalency in the primary outcome of prostate cancer specific mortality. The major criticism of this trial relates to the degree of PSA testing in the control arm of the study, which has been interpreted by many, including by the United States Preventative Services Task Force, as ″approximately 50% of men in the control group received at least 1 PSA test during the study.″ (Source: The Journal of Urology)

Phosphorylation of TOPK at Y74, Y272 by Src increases the stability of TOPK and promotes tumorigenesis of colon.

Mon, 28 Mar 2016 17:23:02 +0100

Authors: Xiao J, Duan Q, Wang Z, Yan W, Sun H, Xue P, Fan X, Zeng X, Chen J, Shao C, Zhu F Abstract T-LAK cell-originated protein kinase (TOPK), a serine/threonine protein kinase, is highly expressed in a variety of tumors and associated with a poor prognosis of human malignancies. However, the activation mechanism of TOPK is still unrevealed. Herein, first we found that Src directly bound with and phosphorylated TOPK at Y74 and Y272 in vitro. Anti-phospho-TOPK at Y74 was prepared, the endogenous phosphorylation of TOPK at Y74 was detected in colon cancer cells, and the phosphorylation was inhibited in cells expressing low levels of Src. Subsequently, we stably transfected Y74 and Y272 double mutated TOPK (TOPK-FF) into JB6 or SW480 cells, and observed that both the anchorage-indep...

The U.S. Throws Out $3 Billion In Cancer Drugs Every Year

Mon, 28 Mar 2016 15:39:32 +0100

(Reuters Health) - U.S. doctors and hospitals throw out almost $3 billion (roughly 2.7 billion euros) in unused cancer drugs each year because the medicines come in supersized single-use packages and excess medicine must be discarded for safety reasons, a recent paper suggests. Researchers focused on 20 expensive medicines that are given by injection or intravenous drip and require doses adjusted based on the patient’s body size. Often, the packages contain much more medicine than patients need, and the leftovers wind up in the trash. Even when much of the medicine goes in the garbage, patients pay for the whole vial, said lead author Dr. Peter Bach, director of the Center for Health Policy and Outcomes at Memorial Sloan Kettering Cancer Center in New York City. “...

TUSC3 promotes colorectal cancer progression and epithelial–mesenchymal transition (EMT) through WNT/β‐catenin and MAPK signalling

Sun, 27 Mar 2016 22:00:00 +0100

In conclusion, our study demonstrated the oncogenic role of TUSC3 in CRC and showed that TUSC3 may be responsible for alternations in the proliferation ability, aggressiveness, and invasive/metastatic potential of CRC through regulating the MAPK, PI3K/Akt, and Wnt/β‐catenin signalling pathways.

SERPINI1 regulates epithelial–mesenchymal transition in an orthotopic implantation model of colorectal cancer

Sun, 27 Mar 2016 22:00:00 +0100

An increasingly accepted concept is that the progression of colorectal cancer is accompanied by epithelial–mesenchymal transition (EMT). In our study, in order to characterize the properties of EMT in 16 colorectal cancer cell lines, the cells were first orthotopically implanted into nude mice, and the tumors in vivo, as well as cells cultured in vitro, were immunostained for EMT markers. The immunostaining revealed that seven of the cells had an epithelial phenotype with a high expression of E‐cadherin, whereas other cells showed opposite patterns, such as a high expression of vimentin (CX‐1, COLO205, CloneA, HCT116, and SW48). Among the cells expressing vimentin, some expressed vimentin in the orthotopic tumors but not in the cultured cells (SW480, SW620, and COLO320). We evaluated...



Autophagy inhibition sensitizes WYE-354-induced anti-colon cancer activity in vitro and in vivo

Sun, 27 Mar 2016 22:00:00 +0100

Abstract Mammalian target of rapamycin (mTOR) complex 1 (mTORC1) and mTORC2 are frequently dysregulated in human colon cancers. In the present study, we evaluated the potential anti-colon cancer cell activity by a novel mTORC1/2 dual inhibitor WYE-354. We showed that WYE-354 was anti-survival and anti-proliferative when adding to primary (patient-derived) and established (HCT-116, HT-29, Caco-2, LoVo, and DLD-1 lines) colon cancer cells. In addition, WYE-354 treatment activated caspase-dependent apoptosis in the colon cancer cells. Mechanistically, WYE-354 blocked mTORC1 and mTORC2 activation. Meanwhile, it also induced autophagy activation in the colon cancer cells. Autophagy inhibitors (bafilomycin A1 and 3-methyladenine), or shRNA-mediated knockdown of autophagy elements (Becli...

Extrahepatic Manifestations of Nonalcoholic Fatty Liver Disease

Sun, 27 Mar 2016 22:00:00 +0100

Abstract Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide with an increased prevalence of metabolic, macro-, and microvascular complications. The primary causes of mortality in NAFLD are cardiovascular disease (CVD), malignancy, and liver disease. NAFLD is a multisystem disease that affects a variety of extrahepatic organ systems. The main focus of this review is to summarize the reported extrahepatic associations, which include CVD, chronic kidney disease, obstructive sleep apnea, osteoporosis, psoriasis, colorectal cancer, iron overload, and various endocrinopathies (e.g., type 2 diabetes mellitus, thyroid dysfunction, and polycystic ovarian syndrome). Due to the systemic manifestations of NAFLD, patients require a multidiscipl...



Sciellin mediates mesenchymal-to-epithelial transition in colorectal cancer hepatic metastasis.

Sun, 27 Mar 2016 05:28:02 +0100

Authors: Chou CK, Fan CC, Lin PS, Liao PY, Tung JC, Hsieh CH, Hung MC, Chen CH, Chang WC Abstract Hepatic metastasis is the major cause of mortality in colorectal cancer (CRC) patients. Using proteomic analysis, we found sciellin (SCEL) to be specifically expressed in hepatic metastatic CRC cell lines. SCEL knockdown increased CRC cell migration and invasion, while overexpression had the opposite effect. SCEL knockdown also caused cancer cells to form more invasive structures within 3D cultures, increased the mesenchymal marker vimentin, and attenuated the epithelial marker E-cadherin. SCEL increased WNT signaling by activating β-catenin and its downstream target c-myc, and activated mesenchymal-to-epithelial transition (MET) through a SCEL-β-catenin-E-cadherin axis. SCEL showed ...

Authors: Price TJ, Thavaneswaran S, Burge M, Segelov E, Haller DG, Punt CJ, Arnold D, Karapetis CS, Tebbutt NC, Pavlakis N, Gibbs P, Shapiro JD Abstract The treatment of metastatic CRC (mCRC) has evolved over the last 20 years, from fluoropyrimidines alone to combination chemotherapy and new biologic agents. Median overall survival is now over 24 months for RAS mutated (MT) patients and over 30 months for RAS wild-type (WT) patients. However, there are subgroups of patients with BRAF V600E MT CRC who have a significantly poorer outlook. Newer treatment options are also being explored in select subgroups of patients (anti-HER 2 in HER2 positive mCRC and immunotherapy in patients with defective mismatch repair (dMMR)).

Loss of TINCR expression promotes proliferation, metastasis through activating EpCAM cleavage in colorectal cancer.

Fri, 25 Mar 2016 17:33:04 +0100

Authors: Zhang ZY, Lu YX, Zhang ZY, Chang YY, Zheng L, Yuan L, Zhang F, Hu YH, Zhang WJ, Li XN Abstract Long non-coding RNAs (lncRNAs) are involved in kinds of human diseases, including colorectal cancer (CRC). TINCR, a 3.7 kb long non coding RNA, was associated with cell differentiation in keratinocyte and gastric cancer cells. However, little is known about the role of TINCR in regulation CRC progression. Here, we showed that lncRNA TINCR was associated with CRC proliferation and metastasis. TINCR was statistically downregulated in CRC tissues and metastatic CRC cell lines compared with their counterparts. TINCR was reversely correlated with CRC progression and promoted tumor cells growth, metastasis in vivo and in vitro. While overexpression of TINCR had opposite effect. In addi...



Decreased level of RASSF6 in sporadic colorectal cancer and its anti-tumor effects both in vitro and in vivo.

Fri, 25 Mar 2016 17:33:04 +0100

In this study, we demonstrate that RASSF6 acts as a tumor suppressor in colon cancer cells. Decreased level of RASSF6 was observed in adenocarcinoma compared to normal tissues, especially in advanced tumor cases. Further experiments showed exogenous introduction of RASSF6 into LoVo cells suppressed cell proliferation, migration, invasion, and induced apoptosis in vitro as well as tumor growth in vivo. In contrast, knockdown of RASSF6 in HT-29 cells showed the opposite effects. Taken together, our results suggest, in addition to epigenetics changes, functional somatic mutations may also contribute to the downregulation of RASSF6 and further participate in the pathogenesis of sCRC. RASSF6 may serve as a novel candidate against tumor growth for sCRC. PMID: 27009808 [PubMed - as supplied b...

DDX3 enhances oncogenic KRAS‑induced tumor invasion in colorectal cancer via the β‑catenin/ZEB1 axis.

Fri, 25 Mar 2016 17:33:04 +0100

In conclusion, DDX3 may play an oncogenic role to promote tumor growth and invasion in colon cancer cells via the β-catenin/ZEB1 axis due to increasing KRAS transcription. We therefore suggest that AKT or β-catenin may potentially act as a therapeutic target to improve tumor regression and outcomes in colorectal cancer patients who harbored high-DDX3 tumors.

Integrated analysis of long non-coding RNAs in human colorectal cancer.

Fri, 25 Mar 2016 17:33:04 +0100

Authors: Chen X, Liu B, Yang R, Guo Y, Li F, Wang L, Hu H Abstract Accumulating evidence highlights the role of long non-coding RNAs (lncRNAs) in tumors. However, the genome-wide expression and roles of lncRNAs in colorectal cancer (CRC) remain unknown. Here, we systematically examined the global gene expressions in primary and synchronous liver metastases CRC tissue, in which thousands of aberrantly expressed lncRNAs were characterized. Co-expression analysis revealed that some lncRNAs correlated to their neighboring mRNAs in expression levels, whereas others formed networks with protein-coding genes in trans. We observed H3K4me3 was enriched at expressed lncRNA transcription start sites (TSSs) and correlated to dysregulated lncRNAs. Furthermore, we identified primary and metastas...

Hepatic Perfusion Therapy

Fri, 25 Mar 2016 15:35:28 +0100

Isolated hepatic perfusion uses the unique vascular supply of hepatic malignancies to deliver cytotoxic chemotherapy. The procedure involves vascular isolation of the liver and delivery of chemotherapy via the hepatic artery and extraction from retrohepatic vena cava. Benefits of hepatic perfusion have been observed in hepatic metastases of ocular melanoma and colorectal cancer and primary hepatocellular carcinoma. Percutaneous and prophylactic perfusions are avenues of ongoing research. (Source: Surgical Clinics of North America)

Cancer-Associated Immune Resistance and Evasion of Immune Surveillance in Colorectal Cancer.

Fri, 25 Mar 2016 00:16:02 +0100

Authors: Parcesepe P, Giordano G, Laudanna C, Febbraro A, Pancione M Abstract Data from molecular profiles of tumors and tumor associated cells provide a model in which cancer cells can acquire the capability of avoiding immune surveillance by expressing an immune-like phenotype. Recent works reveal that expression of immune antigens (PDL1, CD47, CD73, CD14, CD68, MAC387, CD163, DAP12, and CD15) by tumor cells "immune resistance," combined with prometastatic function of nonmalignant infiltrating cells, may represent a strategy to overcome the rate-limiting steps of metastatic cascade through (a) enhanced interactions with protumorigenic myeloid cells and escape from T-dependent immune response mediated by CD8+ and natural killer (NK) cells; (b) production of immune mediators that e...

Transcriptional signature induced by a metastasis‐promoting c‐Src mutant in a human breast cell line

Thu, 24 Mar 2016 23:00:00 +0100

Deletions at the C‐terminus of the proto‐oncogene protein c‐Src kinase are found in the viral oncogene protein v‐Src as well as in some advanced human colon cancers. They are associated with increased kinase activity and cellular invasiveness. Here, we analyzed the mRNA expression signature of a constitutively active C‐terminal mutant of c‐Src, c‐Src(mt), in comparison with its wild‐type protein, c‐Src(wt), in the human non‐transformed breast epithelial cell line MCF‐10A. We demonstrated previously that the mutant altered migratory and metastatic properties. Genome‐wide transcriptome analysis revealed that c‐Src(mt) de‐regulated the expression levels of approximately 430 mRNAs whose gene products are mainly involved in the cellular processes of migration and adh...



Cancer Stage in American Indians and Alaska Natives Enrolled in Medicaid

Thu, 24 Mar 2016 23:00:00 +0100

Conclusions In contrast to the general population of the U.S., among Medicaid enrollees, AI/AN race is not associated with later stage at diagnosis. Cancer survival disparities associated with AI/AN race that have been observed in the broader population may be driven by factors associated with income and health insurance that are also associated with race, as income and insurance status are more homogenous within the Medicaid population than within the broader population.

Solid cancer incidence among Chinese medical diagnostic x‐ray workers, 1950–1995: Estimation of radiation‐related risks

Thu, 24 Mar 2016 23:00:00 +0100

The objective of this study was to estimate solid cancer risk attributable to long‐term, fractionated occupational exposure to low doses of ionizing radiation. Based on cancer incidence for the period 1950–1995 in a cohort of 27,011 Chinese medical diagnostic X‐ray workers and a comparison cohort of 25,782 Chinese physicians who did not use X‐ray equipment in their work, we used Poisson regression to fit excess relative risk (ERR) and excess absolute risk (EAR) dose–response models for incidence of all solid cancers combined. Radiation dose reconstruction was based on a previously published method that relied on simulating measurements for multiple X‐ray machines, workplaces and working conditions, information about protective measures, including use of lead aprons, and work hi...



Unbiased identification of substrates of protein tyrosine phosphatase ptp-3 in C. elegans

Thu, 24 Mar 2016 23:00:00 +0100

The leukocyte antigen related (LAR) family of receptor-like protein tyrosine phosphatases has three members in humans – PTPRF, PTPRD and PTPRS – that have been implicated in diverse processes including embryonic development, inhibition of cell growth and axonal guidance. Mutations in the LAR family are associated with developmental defects such as cleft palate as well as various cancers including breast, neck, lung, colon and brain. Although this family of tyrosine phosphatases are important for many developmental processes, little is known of their substrates. (Source: Molecular Oncology)

Laparoscopic resection of transverse colon cancer at splenic flexure: technical aspects and results

Thu, 24 Mar 2016 23:00:00 +0100

Abstract Laparoscopic resection of transverse colon cancer at splenic flexure is technical demanding and its efficacy remains controversial. The aim of this study was to investigate its technical aspects such as pitfalls and overcoming them, and to demonstrate the short-term and oncologic long-term outcomes. To overcome the difficulty in laparoscopic resection of transverse colon cancer at splenic flexure, we recognized the following technical tips as essential. First of all, we have to precisely identify major vessels variations feeding tumor. Secondary, anatomical dissection of mesocolon through medial approach is indispensible. Third, safe takedown of splenic flexure to fully mobilization of left hemicolon is mandatory. This cohort study analyzed 95 patients with stage II (43) ...



Current Understanding of HSP90 as a Novel Therapeutic Target: An Emerging Approach for the Treatment of Cancer.

Thu, 24 Mar 2016 23:00:00 +0100

Authors: Haque A, Alam Q, Alam MZ, Azhar EI, Sait KH, Anfina N, Mushtaq G, Kamal MA, Rasool M Abstract Heat Shock Protein 90 (HSP90) is a ubiquitous molecular chaperone that is considered to be the most abundantly expressed protein in various human cancers such as breast, lung, colon, prostate, leukemia and skin. The master regulator, HSP90 plays a pivotal role in the conformational stabilization, maturation and activity of its various labile oncogenic client proteins such as p53, ErbB2, Bcr-Abl, Akt, Her-2, Cdk4, Cdk6, Raf-1 and v-Src in altered cells. Hence, making a guaranteed attempt to inhibit such a master regulator for cancer therapy appears to be a potential approach for combinatorial inhibition of numerous oncogenic signaling pathways simultaneously. Considerable efforts a...

This Disease Can Still Get You Quarantined For Months -- And It's On The Rise

Thu, 24 Mar 2016 17:08:03 +0100

In August 2014, Kate O’Brien, a 34-year-old media producer from Brooklyn, found out she was expecting her second child. She was ecstatic. But this pregnancy didn't proceed like the first. For the next few months, O'Brien had a cold she couldn't shake. She woke up in the middle of the night drenched in sweat. She wanted to blame it on her pregnancy, yet she kept losing weight. She could barely eat. She coughed up balls of bloody mucus. Her throat burned. None of her doctors could figure out what was wrong. A physician sent her to Mount Sinai West Hospital in Manhattan in January 2015, when, at five months pregnant, she still couldn't gain any weight. "No one likes a skinny pregnant lady," she said.

β‐lactoglobulin–pectin Nanoparticle‐based Oral Drug Delivery System for Potential Treatment of Colon Cancer

Wed, 23 Mar 2016 23:00:00 +0100

Colon cancer is one of the most common internal malignancies, and conventional chemotherapy is not effective in its treatment. Nanoparticles hold tremendous potential as an effective drug delivery system. The physicochemical properties of β‐lactoglobulin, the main whey protein of cow's milk, such as its stability at low pH, its resistance to gastric protease, and its ability to bind hydrophobic ligands, give it potential for transporting drugs specifically for colon cancer. In the present research, β‐lactoglobulin–pectin nanoparticles were designed to transfer a newly synthesized, anticancer platinum complex (bipyridine ethyl dithiocarbamate Pt(II) nitrate), to the colon. The effects of multiple factors on the size and the colloidal stability of the nanoparticles were studied using...
