BACKGROUND: The high morbidity associated with radical resection for rectal cancer is an incentive for surgeons to adopt strategies aimed at organ preservation, particularly for early disease. There are a number of different approaches to achieve this. In this study we have collated current national and international guidelines to produce a synopsis to support this changing practice. METHODS: The databases PubMed, Embase, Trip database, national guideline clearinghouse, BMJ Best practice were interrogated...

Importance: Mismatch repair (MMR) deficiency of DNA has been observed in up to 15% of sporadic colorectal cancers (CRCs) and is a characteristic feature of Lynch syndrome, which has a higher incidence in young adults (age, <50 years) with CRC. Mismatch repair deficiency can be due to germline mutations or epigenetic inactivation, affects prognosis and response to systemic therapy, and results in unrepaired repetitive DNA sequences, which increases the risk of multiple malignant tumors...

BACKGROUND: A subset of patients with rectal cancer who undergo neoadjuvant chemoradiation therapy will develop a complete pathologic tumor response. Complete nodal response is not universal in these patients and is difficult to assess clinically. Quantifying the risk of nodal disease would allow for targeted therapy with either radical resection or "watchful waiting." OBJECTIVE: This study aimed to identify risk factors for residual nodal disease in ypT0 rectal adenocarcinoma...

BACKGROUND: It is unclear whether traveling long distances to high-volume centers would compensate for travel burden among patients undergoing rectal cancer resection. OBJECTIVE: The purpose of this study was to determine whether operative volume outweighs the advantages of being treated locally by comparing the outcomes of patients with rectal cancer treated at local, low-volume centers versus far, high-volume centers. DESIGN: This was a population-based study...

BACKGROUND: Transanal total mesorectal excision (TaTME) seems to be a valid alternative to the open or laparoscopic TME. Quality of the TME specimen is the most important prognostic factor in rectal cancer. This study shows the pathological results of the largest single-institution series published on TaTME in patients with mid and low rectal cancer. METHODS: We conducted a retrospective cohort study of all consecutive patients with rectal cancer, treated by TaTME between November 2011 and June 2016...

We report 2 unusual cases of Stage IV rectal cancer for which pathological complete response was achieved with neoadjuvant chemotherapy(NAC)consisting of a combination of 5-fluorouracil(5-FU), oxaliplatin, Leucovorin(mFOLFOX6)or irinotecan(FOLFIRI), and bevacizumab, without radiotherapy. Case 1: A 65-year-old man was diagnosed as having rectal cancer with an invasive carcinoma of the prostate and lymph node metastasis. He refused to undergo surgery and received NAC instead. After NAC with mFOLFOX6 and FOLFIRI was performed, CT scan and colonoscopy revealed no evidence of disease...
