We investigated retrospectively whether immunologic markers from a complete blood count (CBC) are associated with the responsiveness to preoperative chemoradiotherapy (PCRT) and oncologic outcomes in 984 patients with locally advanced rectal cancer (LARC) who also underwent radical surgery from 2005 to 2013. CBC parameters including the neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), and platelet to lymphocyte ratio (PLR) were recorded. Pathologic responses to PCRT were evaluated in the resected specimens using the tumor regression grade system...

AIMS: The clinical outcome of patients with locally advanced rectal cancer submitted to neo-adjuvant chemo-radiotherapy (CRT) is influenced by tumour response to treatment, which is reflected by tumour regression grade (TRG) and post-treatment (y) TNM stage. Little is known on the prognostic value of pre-treatment histopathological features of the tumour which may be useful to discriminate potential non-responders and to design tailored therapeutic strategies. In this study, we aimed to investigate the prognostic role of poorly differentiated clusters (PDC) of neoplastic cells in pre-treatment biopsies of rectal cancer submitted to neo-adjuvant CRT...

Preoperative neoadjuvant chemoradiotherapy (nCRT) is the gold standard in locally advanced rectal cancer, only 10-30% of patients achieving benefits. Currently, there is a need of a reliable selection of markers for the identification of poor or non-responders prior to therapy. In this work, we compared protein profiles before therapy of patients differing in their responses to nCRT to find novel predictive markers of response to therapy. Patients were grouped into 3 groups according to their tumor regression grading (TRG) after surgery: 'TRG 1-2', good responders, 'TRG 3' and 'TRG 4', poor responders...

BACKGROUND: In locally advanced rectal adenocarcinoma, 15% to 20% of patients treated with neoadjuvant chemoradiation (nCRT) achieve a pathologic complete response (pCR). The benefit of adjuvant chemotherapy is controversial in rectal cancer. Our objective was to evaluate the effect of clinical risk factors and adjuvant chemotherapy usage on the outcomes of the pCR patient population. PATIENTS AND METHODS: We performed a retrospective study using the National Cancer Data Base from 2006 to 2013...

PURPOSE: Preoperative chemoradiotherapy (CRT) using 5-fluorouracil (5-FU)-based chemotherapy is the standard of care for rectal cancer. The effect of additional chemotherapy during the period between the completion of radiotherapy and surgery remains unclear. Predictive factors for CRT may differ between combination chemotherapy with S-1 and with tegafur-uracil/leucovorin (UFT/LV). METHODS: The subjects were 54 patients with locally advanced rectal cancer who received preoperative CRT with S-1 or UFT/LV...

BACKGROUND: During the past 20 years, considerable improvement has occurred in the treatment of patients with locally advanced rectal cancer (LARC). With the introduction of multimodal treatment, refinements in preclinical staging and improvements in surgical skills, local relapse is no longer the major problem for patients with LARC. However, many patients die of metastatic disease. The present phase Ib study aimed to establish the maximum tolerated dose of everolimus combined with 5-fluorouracil and radiotherapy in patients with LARC...

INTRODUCTION: Major pathologic regression after neoadjuvant therapy is a strong and favorable prognostic factor in several types of cancer (breast, rectal and bladder). This information is less clear and has yet to be systematically evaluated in upper gastrointestinal tumors. We performed a meta-analysis to evaluate the prognostic impact of tumor regression after preoperative therapy on disease-free survival (DFS) and overall survival (OS) in gastro-esophageal cancer patients. METHODS: we searched for relevant articles in PubMed, SCOPUS, Web of Science, CINAHL, LILACS, Ovid, Cochrane Library, Google Scholar and Embase up to June 2, 2016...

We explain the state of the art of the immunohistochemical markers of response in rectal cancers treated with neoadjuvant medical therapies and its implication with prognosis. Neoadjuvant chemoradiotherapy is widely used to improve the outcome of patients with locally advanced rectal cancer, and the evaluation of the effects of medical therapy is to date based on histomorphological examination by applying four grading systems of response to therapy (tumor regression grade (TRG)). The need to identify immunohistochemical markers that could ensure a better assessment of response and possibly provide additional prognostic information has emerged...

BACKGROUND: Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. OBJECTIVE: This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach...

OBJECTIVE: To evaluate the feasibility of on-board diffusion-weighted imaging (DWI) with an integrated low-field MRI radiotherapy system to assess responses to neoadjuvant chemoradiation (NAC) in rectal cancer. METHODS: A spin echo-based planar imaging diffusion sequence on a 0.35-T MRI radiotherapy system was acquired over the course of NAC. The apparent diffusion coefficients (ADCs) from the tumour regions of interest (ROIs) were calculated. A functional diffusion map (fDM) was created showing a pixelwise ADC analysis of the ROI over the course of treatment...
