Purpose: Most patients with rectal cancer undergo a total mesorectal excision and a partial resection of the sigmoid colon to improve oncologic outcomes. The aim of this study was to assess the distribution of lymph nodes (LNs) in rectal cancer. Methods: The records of 54 patients with mid and low rectal cancer between April 2015 and March 2017 were reviewed, and 49 patients were enrolled in this study. All harvested LNs were analyzed according to the harvested area: the mesorectum area (MA), the vascular pedicle area (VA), and the sigmoid area (SA)...

Background: Although people living with HIV or AIDS (PLWHA) are at higher risk for many cancers, breast, prostate, and colorectal cancer rates are lower in this patient population. Because these tumors are often screen-detected, these inverse associations could be driven by HIV-related differences in utilization of cancer screening. Methods: We ascertained incident breast, prostate, and colorectal cancer in PLWHA using data from the HIV/AIDS Cancer Match Study (1996-2012)...

BACKGROUND: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in the US. CRC survivors may have complex healthcare needs requiring care from both specialists and primary care. Our objective was to understand how CRC survivors perceive their survivorship care, especially management of their cardiovascular-related chronic diseases. METHODS: We identified patients diagnosed with non-metastatic CRC between 10/1/2007 and 12/31/2015 at Veterans Affairs Medical Centers in North Carolina or Virginia...

BACKGROUND: Colorectal cancer (CRC) is the second leading cause for cancer-related death in industrialized nations. Nodal involvement has been identified as a relevant prognostic feature in CRC. Extra nodal metastasis (ENM) describes the spread of malignant cells beyond the nodal capsule. ENM is thought to be an independent risk factor for poor survival. This study examined ENM as an independent risk factor for poor overall survival in patients with node-positive CRC. MATERIALS AND METHODS: Data from a prospectively maintained CRC database was retrospectively analyzed...

BACKGROUND: Observational studies have shown that physical activity levels are inversely, and sedentary behaviours are positively, associated with colorectal cancer risk; however, whether these relationships are consistent across anatomical subsites is uncertain. METHODS: We investigated the associations between colorectal cancer and physical activity (metabolic equivalents (METs)-hours per week), and indicators of sedentary behaviour (television watching time and time spent using computers) among 430 584 men and women enroled in the UK Biobank...

Few prospective cohort studies in the UK have specifically focused on the associations between commonly consumed dietary patterns and colorectal cancer (CRC). The aim of this study was to assess whether red meat, poultry, fish and vegetarian dietary patterns are associated with differences in the incidence of cancers of colon and rectum in the UKWCS. Four common dietary patterns were defined based on a hierarchy of consumption of red meat, poultry, and fish for each cohort participant, using a 217-item food frequency questionnaire...

BACKGROUND: Nut consumption is known to reduce the risk of obesity, diabetes mellitus, and cardiovascular disease. However, in previous studies, portion sizes and categories of nut consumption have varied, and few studies have assessed the association between colorectal cancer risk and nut consumption. In this study, we investigated the relationship between nut consumption and colorectal cancer risk. METHODS: A case-control study was conducted among 923 colorectal cancer patients and 1846 controls recruited from the National Cancer Center in Korea...

Colorectal cancer (CC) in Poland is the type of cancer with the highest dynamics of disease growth and is epidemiologically related to age. The analysis involved 353 patients operated on due to CC in senile and old age and compared with younger patients. It was found that people at this age are more often diagnosed with CC They were more often women, the patients did not differ in the stage of cancer, while they were significantly more often qualified for surgery due to urgent indications. In patients with colonic cancer, the resectability and radicality of the procedures in comparison with patients with rectal cancer was significantly higher, while there were more complications and deaths in the 30-day follow-up in this group...

BACKGROUND: Obesity and physical activity (PA) are predictors of colon (CC) and rectal (RC) cancers. Prolonged sitting is also emerging as a potential predictor for these cancers. Little knowledge exists about the interactive effects of obesity, PA and prolonged sitting on cancer risk. This analysis assessed independent and interactive effects of PA, body mass index (BMI) and sitting time on CC and RC risks. METHODS: This analysis used data from a prospective study of 226,584 participants aged 45 years and over in New South Wales (NSW), Australia, who joined the 45 and Up study between 2006 and 2009...

BACKGROUND: Few data are available on the management of elderly rectal cancer patients, and especially on the ability to provide optimal oncological treatment. The aim of this study was to determine the feasibility and results of multimodality treatment for rectal cancer in patients 75years and older after simplified comprehensive geriatric assessment (CGA) according to Balducci score. METHODS: We reviewed the charts of elderly patients who underwent surgery for localized middle or low rectal cancer...

Log odds of positive nodes (LODDS), defined as the log of the ratio between the number of positive nodes and the number of negative nodes, has been recently introduced as a tool in predicting prognosis. This study aims to establish the effective and prognostic value of LODDS in predicting the survival outcome of CRC patients undergoing surgical resection. The study population is represented by 323 consecutive patients with primary colon or rectal adenocarcinoma thatunderwent curative resection. LODDS values were calculated by empirical logistic formula, log(pnod + 0...

The case was for a male at the age of 80. We performed laparoscopic left hemicolectomy and D3 lymph node dissection for descending colon cancer. He had a good postoperative prognosis and was discharged on the 14th day after the operation. Later, he was receiving the treatment on an outpatient basis without postoperative adjuvant chemotherapy during the followup period. He visited the hospital for sudden abdominal pain and melena as chief complaint approximately 4 months after the operation. We found prominent edematous wall thickening and increased surrounding fat concentration in the anal side of colon from the anastomosis site with plain abdominal CT scan...

Epithelial-to-mesenchymal transition (EMT) has been closely linked with therapy resistance and cancer stem cells (CSCs). However, EMT pathways have proven challenging to therapeutically target. MicroRNA 145 (miR-145) targets multiple stem cell transcription factors and its expression is inversely correlated with EMT. Therefore, we hypothesized that miR-145 represents a therapeutic target to reverse snail family transcriptional repressor 1 (SNAI1)-mediated stemness and radiation resistance (RT). Stable expression of SNAI1 in DLD1 and HCT116 cells (DLD1-SNAI1; HCT116-SNAI1) increased expression of Nanog and decreased miR-145 expression compared to control cells...

BACKGROUND: Colorectal cancer is the fourth most diffuse cause of death in the world and local recurrence is associated with a reduced long-term life expectancy, with a reduced quality of life. Rectal washout at the anastomosis site leads to a statistically significant reduction of local recurrences. METHODS: We developed the idea of a new laparoscopic stapler with an integrated washout system that could decontaminate the rectal stump before resection, without the need to enlarge the standard surgical incision or even to distort the incision site, closing the rectal stump just below the inferior part of the cancer, and then proceeding with the resection and stapling of the distal part of the tumor...

Minimally invasive colorectal resection (MICR) for colorectal cancer (CRC) is associated with elevated levels of seven proangiogenic proteins that persist for 2-4 weeks after surgery. The proangiogenic plasma may promote tumor growth postoperatively in patients with residual cancer. To the best of our knowledge, the impact of surgery on interleukin 8 (IL-8) levels is unknown. The aim of the present study was to evaluate plasma IL-8 levels after MICR for CRC. Patients with CRC enrolled in an institutional review board-approved plasma/data bank who underwent MICR were eligible...

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...

Formation of a colonic J-pouch with anastomosis to the rectal stump is an accepted form of reconstruction after low anterior resection (LAR) for rectal carcinoma. It is thought this can help prevent the onset of LAR syndrome as well as improve the quality of life in the first two years following surgery. Rectovaginal fistulation is a recognised complication of this form of surgery usually occurring because of technical failure leading to inclusion of the vaginal wall into the stapled anastomosis. We present an as of yet unreported case of fistulation between the upper horizontal staple line of a colonic J-pouch-the tip of the 'J'-which was formed extracorporeally with the posterior vaginal fornix...
