We report a unique case of a 79-year-old woman with metastatic rectal cancer who developed bowel obstruction following endoscopic cryotherapy with liquid nitrogen for palliation of bleeding in the rectum. She developed abdominal distention and pain following the procedure. Computed tomography of the abdomen revealed a paraumbilical hernia containing a segment of transverse colon resulting in partial bowel obstruction. It appears that the recurrent freeze-thaw cycles with poor decompression of the colon despite active venting suction during cryotherapy may have resulted in bowel distention and collapse, causing conformational changes resulting in partial bowel obstruction due to a paraumbilical hernia...

BACKGROUND: To assess pattern distribution and prognosis of the three anatomical entities of metastatic colorectal cancer, and influence of treatment of metastases on survival. METHODS: Patients presenting with stage IV colorectal cancer (synchronous group), or who developed metastatic recurrence (metachronous group) after initial curative treatment between January 2005 and August 2015 were reviewed. Right sided (cecum to transverse colon), left sided (splenic flexure to sigmoid colon) and rectal cancers were identified...

Genomic rearrangements that give rise to oncogenic gene fusions can offer actionable targets for cancer therapy. Here we present a systematic analysis of oncogenic gene fusions among a clinically well-characterized, prospectively collected set of 278 primary colon cancers spanning diverse tumor stages and clinical outcomes. Gene fusions and somatic genetic variations were identified in fresh frozen clinical specimens by Illumina RNA-sequencing, the STAR fusion gene detection pipeline, and GATK RNA-seq variant calling...

BACKGROUND: The feasibility and efficacy of adjuvant hepatic arterial infusion (HAI) in preventing the development of liver metastases in patients with advanced colon carcinoma have not been validated. The aim of this randomized controlled study was to compare the feasibility of HAI and the protective effect against liver metastasis after curative resection to those of systemic chemotherapy. METHODS: Between July 2000 and June 2003, 91 patients were enrolled. Patients were randomly assigned to receive 5-fluorouracil (5-FU) via continuous venous infusion (CVI) or intra-hepatic arterial weekly high-dose 5-FU (WHF)...

ALDH has been shown to be a marker that denotes a sub-population of cancer stem cells in colorectal and other cancers. This sub-population of cells shows an increased risk for tumor initiation, metastasis, and resistance to chemotherapy and radiation resulting in recurrence and death. It is thus essential to identify the important signaling pathways related to ALDH1+ CSCs in colon cancer. The essential issue becomes to isolate pure sub-populations of cells from heterogeneous tissues for further analysis. To achieve this goal, tissues from colorectal cancer Stage III patients were immuno-stained with ALDH1 antibody...

OBJECTIVE: To evaluate the outcomes of a randomized controlled trial, which assigned patients with post-cancer fatigue (PCF) to education, or 12-weeks of integrated cognitive-behavioral therapy (CBT) and graded exercise therapy (GET). METHODS: Three months post treatment for breast or colon cancer, eligible patients had: clinically-significant fatigue; no co-morbid medical or psychiatric conditions which explained the fatigue; and no evidence of recurrence. The CBT/GET arm included individually tailored consultations at approximately two weekly intervals...

Dysfunction of microRNAs (miRNAs) is strongly proved to participate in the pathogenesis and tumorigenicity of colorectal cancer (CRC). miR-944 was reported to play either oncogenic or tumor suppressive roles in human cancers. A recent study reported that the levels of miR-944 in recurrent CRC patients were evidently lower than that in non-recurrent cases, suggesting that miR-944 may function as a tumor suppressive miRNA in CRC. Yet, the clinical value and biological function of miR-944 remain rarely known in CRC...

Spontaneous regression (SR) of many malignant tumors has been well documented, with an approximate incidence of one per 60,000-100,000 cancer patients. However, SR of colorectal cancer (CRC) is very rare, accounting for less than 2% of such cases. We report a case of SR of transverse colon cancer in an 80-year-old man undergoing outpatient follow-up after surgical treatment of early gastric cancer. Colonoscopy (CS) revealed a Borrmann type II tumor in the transverse colon measuring 30 × 30 mm. Because the patient underwent anticoagulant therapy, we did not perform a biopsy at that time...

BACKGROUND: Colon cancer (CC) is a heterogeneous disease influenced by complex gene networks. As such, the relationship between networks and CC should be elucidated to obtain further insights into tumour biology. RESULTS: Weighted gene co-expression network analysis, a powerful technique used to extract co-expressed gene networks from mRNA expressions, was conducted to identify 11 co-regulated modules in a discovery dataset with 461 patients. A transcriptional module enriched in cell cycle processes was correlated with the recurrence-free survival of the CC patients in the discovery (HR = 0...

DDIT4 gene encodes a protein whose main action is to inhibit mTOR under stress conditions whilst several in vitro studies indicate that its expression favors cancer progression. We have previously described that DDIT4 expression is an independent prognostic factor for tripe negative breast cancer resistant to neoadjuvant chemotherapy. We herein report that high DDIT4 expression is related to the outcome (recurrence-free survival, time to progression and overall survival) in several cancer types. We performed in silico analysis in online platforms, in pooled datasets from KM Plotter and meta-analysis of individual datasets from SurvExpress...

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop. Cervical polyps found in 2-5% of cases are of low clinical significance and can cause, although rarely, post coital bleedings. Cervical polyps grow during pregnancy and mucorrhoea. Trans vaginal ultrasound (TVU) provides an excellent diagnostic technique to diagnose the size and the anatomic location of endometrial polyps (EPs)...

PURPOSE: It is believed that blood from the superior mesenteric vein and splenic vein mixes incompletely in the portal vein and maintains a streamline flow influencing its anatomic distribution. Although several experimental studies have demonstrated the existence of streamlining, clinical studies have shown conflicting results. We investigated whether streamlining of portal vein affects the lobar distribution of colorectal liver metastases and estimated its impact on survival. METHODS: Data of patients who underwent hepatectomy for colorectal liver metastases were retrospectively collected...

Colorectal cancer (CRC) is a complex cancer disease, and approximately 40% of the surgically cured patients will experience cancer recurrence within 5 years. During recent years, research has shown that CRC treatment should be tailored to the individual patient due to the wide variety of risk factors, genetic factors, and surgical complexity. In this review, we provide an overview of the considerations that are needed to provide an individualized, patient-tailored treatment. We emphasize the need to assess the predictors of CRC, and we summarize the latest research on CRC genetics and immunotherapy...

Since the MOSAIC study, oxaliplatin-based adjuvant chemotherapy has been the standard treatment of stage III colon cancer. Combination therapy with fluoropyrimidines and oxaliplatin has improved overall survival (OS) and reduced the risk of recurrence in patients with resected stage III colon cancer. However, only 20% of patients really benefit from adjuvant chemotherapy, exposing 80% of patients to unnecessary toxicity. Recent analyses of large multicenter adjuvant studies have focused on the prognostication of OS and disease-free survival in stage III colon cancer in order to reduce over-treatment and to find more accurate prognostic tools than those used for adjuvant treatment decision-making in stage II disease...

Colorectal cancer was estimated to have the fourth newest incident rate and to have the second highest death rate in 2015 according to the American Cancer Society. There were an estimated 132,700 new diagnoses of colorectal cancer made and approximately 69,000 deaths in 2015 attributing to this form of cancer. 5-fluorouracil (5-FU) or 5-FU with oxaliplatin (FOLFOX) continues to be the standard treatment protocol for patients presenting with colorectal cancer. However, treatment with FOLFOX and conventional chemotherapy has shown to lead to cancer recurrence and a number of toxic side effects...

Juvenile polyposis syndrome (JPS) is a rare autosomal dominant hereditary disorder, characterized by multiple juvenile polyps in the gastrointestinal tract and an increased risk of colorectal cancer. JPS is most frequently caused by mutations in the SMAD4 or BMPR1A genes. Herein, we report a child with juvenile polyposis syndrome (JPS) with a novel mutation in the SMAD4 gene. An 8-year-old boy presented with recurrent rectal bleeding and was found to have multiple polyps in the entire colon. The histology of the resected polyps was consistent with juvenile polyps...
