A 53-year-old woman was hospitalized due to septic shock after developing pneumococcal pneumonia after undergoing esophageal cancer surgery. Her transverse colon became perforated after receiving antimicrobial chemotherapy; therefore, emergency subtotal colectomy was performed. Fungi detected in both her colon tissue and a drainage sample indicated intestinal mucormycosis. Early intensive treatment with high-dose liposomal amphotericin B was successful, and she was subsequently discharged from the hospital...

Fluorescence tumor imaging using exogenous fluorescent tumor-targeting agents has potential to improve early tumor detection. The fluorescent contrast agent indocyanine green (ICG) is used in medical diagnostics. The aim of the present study is to investigate the tumor imaging capability and the imaging mechanism of i.v. administered ICG in a mouse model of colitis-associated colon cancer. To do this, an azoxymethane/dextran sodium sulfate-induced colon cancer mouse model was used. Ex vivo imaging experiments were performed 1 hour after i...

PURPOSE: Fluorouracil monotherapy, instead of the FOLFOX or FOLFIRI regimen, is administered to patients intolerant to oxaliplatin or irinotecan because of their adverse effects. A prospective clinical trial was designed to evaluate the efficacy and safety of fluorouracil monotherapy combined with panitumumab administered to patients with KRAS wild-type (WT) metastatic colorectal cancer (mCRC) intolerant to oxaliplatin and irinotecan. Screening for potential serum biomarkers to predict early therapeutic responses was conducted...

The infiltration and proliferation of cancer cells in the secondary organs are of great interest, since they contribute to cancer metastasis. However, cancer cell dynamics in the secondary organs have not been elucidated at single-cell resolution. In the present study, we established an in vivo model using two-photon microscopy to observe how infiltrating cancer cells form assemblages from single T-cell lymphomas, EL4 cells, in the secondary organs. Using this model, after inoculation of EL4 cells in mice, we discovered that single EL4 cells infiltrated into the colon...

Treatment for gastrointestinal malignancies has evolved over the past two decades. Long-term outcomes have considerably improved, however a high rate of recurrence persists. With the exception of colon cancer, clear consensus strategies with regards to post-treatment surveillance are lacking. Current surveillance practices in non-colon cancer cases are inadequately based on retrospective case analyses and expert recommendations which are not uniformly consistent.This article presents the key follow-up aspects such as recurrence frequency, timing, localization, and therapeutic efficacy for the most common gastrointestinal tumors, and summarizes current recommendations for early detection of recurrence...

BACKGROUND: Near-infrared quantum dots (NIR QDs) are a new class of fluorescent labels with excellent bioimaging features, such as high fluorescence intensity, good fluorescence stability, sufficient electron density, and strong tissue-penetrating ability. For all such features, NIR QDs have great potential for early cancer diagnosis, in vivo tumor imaging and high resolution electron microscopy studies on cancer cells. RESULTS: In the present study we constructed NIR QDs functionalized with the NT4 cancer-selective tetrabranched peptides (NT4-QDs)...

BACKGROUND: Colorectal cancer (CRC) is one of the most predominant types of cancer, and it is the fourth most common cause of cancer-related death and it is important to diagnose CRC in early stage to decrease the mortality by CRC. In our previous study, we identified a combination of five peptides as a biomarker candidate to diagnose CRC by BLOTCHIP® -MS analysis using a set of healthy control subjects and CRC patients (stage II-IV). The aim of the present study was to validate the serum biomarker peptides reported in our previous study using a second cohort and to establish their potential usefulness in CRC diagnosis...

Systemic treatments for patients with colon cancer has expanded broadly beyond 5-fluorouracil based chemotherapy. For early stage colon cancer patients who are considering adjuvant chemotherapy, multiple factors such as the risk of disease recurrence, absolute survival benefit of chemotherapy, treatment toxicity, and patient comorbid medical conditions must be taken into account. In the metastatic setting, biomarkers such as KRAS/NRAS/BRAF mutation, microsatellite instability status, and left- versus right-sided colon cancer have helped oncologists to tailor systemic treatment regimens, which include chemotherapy, targeted therapy, and immunotherapy...

Besides somatic mutations or drug efflux, epigenetic reprogramming can lead to acquired drug resistance. We recently have identified early stress-induced multi-drug tolerant cancer cells termed induced drug-tolerant cells (IDTCs). Here, IDTCs were generated using different types of cancer cell lines; melanoma, lung, breast and colon cancer. A common loss of the H3K4me3 and H3K27me3 and gain of H3K9me3 mark was observed as a significant response to drug exposure or nutrient starvation in IDTCs. These epigenetic changes were reversible upon drug holidays...

BACKGROUND/AIM: Past studies have suggested that adjuvant capecitabine and oxaliplatin (CAPOX) provides decreased tumor relapse and longer survival in patients with curatively resected colon cancer. We report the first evidence of the feasibility of adjuvant CAPOX in Japanese patients with early colon cancer. PATIENTS AND METHODS: Eligible patients had histologically-confirmed stage II/III colon cancer and received curative resection. The primary endpoint was completion rate of treatment after 8 cycles of adjuvant CAPOX...

Oxaliplatin-based adjuvant chemotherapy has been the standard of care for resected early colon cancer for over a decade. Recent results from the IDEA meta-analysis attempt to address the question of whether 3 or 6 months of adjuvant chemotherapy is preferable in stage III colon cancer. Areas covered: A review of the literature and recent conference presentations was undertaken on the topic of adjuvant therapy for resected early colon cancers. This article reviews the current evidence for adjuvant treatment of stage II and III colon cancer, as well as up-to-date data regarding optimal duration of therapy...

PURPOSE: In this study, we have successfully prepared the hyaluronic acid (HA)-conjugated mesoporous silica nanoparticles loaded with 5-fluorouracil (5-FU) to increase the anticancer efficacy in colon cancers. METHODS: The particles were nanosized and perfectly spherical. In vitro release kinetics clearly showed the enzyme-sensitive release of 5-FU from HA-conjugated 5-FU loaded mesoporous silica nanoparticles (HA/FMSN). RESULTS: The presence of HA on the surface of nanoparticles targeted the CD44 receptors overexpressed in the colon cancer cells In vitro cell viability and apoptosis assay clearly showed the superior anticancer effect of HA/FMSN in HT29 colon cancer cells...

BACKGROUND: Although cancer incidence and mortality is declining, cancer remains among the leading causes of death in the United States. Research shows that cancer morbidity and mortality can be reduced by early detection. Yet, both cancer risks and screening behavior remain understudied in the homeless population. METHODS: Researchers conducted a cross-sectional survey of homeless individuals (n = 201). The analysis describes the demographic, psychosocial, and behavioral associations with cancer screenings and knowledge of the lung cancer screening recommendation...

At early stages of carcinoma progression, epithelial cells undergo a program named epithelial-to-mesenchymal transition characterized by the loss of the major component of the adherens junctions, E-cadherin, which in consequence causes the disruption of cell-cell contacts. Hakai is an E3 ubiquitin-ligase that binds to E-cadherin in a phosphorylated-dependent manner and induces its degradation; thus modulating cell adhesions. Here, we show that Hakai expression is gradually increased in adenoma and in different TNM stages (I-IV) from colon adenocarcinomas compared to human colon healthy tissues...

The biological underpinnings for racial disparities in colorectal cancer (CRC) incidence remain to be elucidated. We have previously reported that the cohesin SA-1 down-regulation is an early event in colon carcinogenesis which is dramatically accentuated in African-Americans. In order to investigate the mechanism, we evaluated single nucleotide polymorphisms (SNPs) for association with SA-1-related outcomes followed by gene editing of candidate SNP. We observed that rs34149860 SNP was significantly associated with a lower colonic mucosal SA-1 expression and evaluation of public databases showed striking racial discordance...

BACKGROUND: Aberrant crypt foci (ACF) are commonly considered the early pre-cancerous lesions that can progress to colorectal cancer (CRC). The available literature data reveal that age, dietary factors and lifestyle can affect the development of several dozen percentages of malignant tumours, including CRC. In the present study, an attempt was made to assess the incidence and growth dynamics of ACF and to determine whether the type of diet affected the development and number of AFC. METHODS: Colonoscopy combined with rectal mucosa staining with 0...

RAC3 is a transcription coactivator, usually overexpressed in several tumors and required to maintain the pluripotency in normal stem cells. In this work we studied the association between RAC3 overexpression on cancer cell stemness and the capacity of this protein to induce cancer stem properties in non tumoral cells. We performed in vitro and in vivo experiments using two strategies: by overexpressing RAC3 in the non tumoral cell line HEK293 and by silencing RAC3 in the human colorectal epithelial cell line HCT116 by transfection...
