Tumor microRNAs Identified by Small RNA Sequencing as Potential Response Predictors in Locally Advanced Rectal Cancer Patients Treated With Neoadjuvant Chemoradiotherapy.

Background/aim: Rectal cancer accounts for approximately one-third of all colorectal cancers. Currently, the standard treatment for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiotherapy (CRT) with capecitabine or 5-fluorouracil followed by curative surgery. Unfortunately, only 20% of patients with LARC present complete pathological response after CRT, whereas in 20-40% cases the response is poor or absent.

C-reactive protein as predictor of anastomotic complications after minimally invasive oesophagectomy.

Background: Anastomotic leaks after oesophagectomy with tabularised stomach replacement are a significant factor in post-operative mortality and morbidity. Early detection and treatment of this complication allow for improving operative and oncological results. When assessing laboratory values - elevation of inflammatory parameters - complicated interpretation is an issue (systemic inflammatory response syndrome, surgical versus non-surgical complication).

Infrared thermal imaging: a potential tool used in open colorectal surgery.

Aim of this pilot study was to assess blood perfusion of bowel in resection lines by means of the infrared thermal imaging in order to choose the best place for anastomosis. The paper brings a first experience with infrared thermal imaging used in colorectal surgery operation from initial observation of the patient with T3 adenomatous carcinoma with no lymph node metastasis. The obtained infrared images show a clear boundary between parts of the intestine with blood perfusion and without it.
