OBJECTIVE: The histologic response to neoadjuvant chemoradiotherapy (CRT) has been intimately related to outcomes in locally advanced rectal cancer. However, reliable prognostic factors have yet to be established. SUBJECTS AND METHODS: The study group comprised 198 patients with locally advanced rectal cancer who received CRT. A modified classification based on the combination of ypStage and tumor regression grade (TRG) was developed. ypStage II with TRG 2 was classified as ypTRGstage IIA, and ypStage II with TRG 3 or 4 was classified as ypTRGstage IIB...

BACKGROUND AND OBJECTIVES: The measurement of tumor regression after neoadjuvant oncological treatment has gained increasing interest because it has a prognostic value and because it may influence the method of treatment in rectal cancer. The assessment of tumor regression remains difficult and inaccurate with existing methods. Dual Energy Computed Tomography (DECT) enables qualitative tissue differentiation by simultaneous scanning with different levels of energy. We aimed to assess the feasibility of DECT in quantifying tumor response to neoadjuvant therapy in loco-advanced rectal cancer...

Preoperative chemoradiotherapy (CRT) followed by mesorectal excision is the standard treatment for patients with locally advanced rectal cancer (LARC). The balance between treatment efficacy and toxicity is a major issue in the clinical management of these patients. There is a requirement for the identification of predictive molecular biomarkers for the response of patients to CRT. The present study aimed to analyze the association between microRNA (miRNA/miR) expression and treatment efficacy in patients with LARC who were treated with preoperative CRT...

The primary curative modality for localized rectal cancer is total mesorectal excision (TME). Local control rate of rectal cancer has been improved after neoadjuvant chemoradiotherapy and even pathological complete response (pCR) has been demonstrated in a significant minority. Patients who achieve pCR to neoadjuvant chemoradiotherapy have an excellent prognosis compared with those without pCR. If the patients with complete response to neoadjuvant chemoradiation can be demonstrated by clinical findings and medical imaging (cCR), a non-operative management (NOM) strategy may be pursued to preserve sphincter function and avoid complications induced by TME, which is a new tendency in the treatment of rectal cancer in recent years...

Objective: Neoadjuvant concurrent chemoradiotherapy (CCRT) is an increasingly common therapeutic strategy for locally advanced rectal cancer, but stratification of risk and final outcomes remain a major challenge. Transcobalamin 1 (TCN1), a vitamin B12 (cobalamin)-binding protein, regulates cobalamin homeostasis. High expression of TCN1 have been reported in neoplasms such as breast cancer and hepatocellular carcinoma. However, little is known about the relevance of TCN1 to rectal cancer receiving CCRT. This study examined the predictive and prognostic impact of TCN1 expression in patients with rectal cancer following neoadjuvant CCRT...

BACKGROUND: In rectal cancer, the significance of abdominopelvic sepsis (APS) on metastatic tumor growth remains uncertain. We aimed to analyze the effect of abdominopelvic sepsis on long-term survival in patients undergoing restorative rectal cancer surgery. METHODS: Data were used from the Belgian PROCARE rectal cancer registry. The effect of abdominopelvic infection on survival was assessed in uni- and multivariable Cox regression models. The effect of clinical and pathological covariates was controlled by propensity score-based matching of cases with controls...

Around 12-15% of patients with locally advanced rectal cancer undergo a pathologically complete response (tumor regression grade 4) to long-course preoperative chemoradiotherapy; the remainder exhibit a spectrum of tumor regression (tumor regression grade 1-3). Understanding therapy-related transcriptional alterations may enable better prediction of response as measured by progression-free and overall survival, in addition to aiding the development of improved strategies based on the underlying biology of the disease...

BACKGROUND: Platinum resistance enhances DNA damage repair through nucleotide excision repair mechanisms involving the excision repair cross-complementing group 1 (ERCC1), X-ray cross-complementing group 1 (XRCC1), and excision repair cross-complementing group 2 (ERCC2). We evaluated the correlation between the expression of these three DNA repair genes and clinical outcomes in patients with rectal cancer receiving FOLFOX-based preoperative chemoradiotherapy (CRT). METHODS: Using immunohistochemistry, we examined the expression of ERCC1, ERCC2, and XRCC1 in pre-CRT cancer tissues from 86 patients with rectal cancer who had undergone curative resection and preoperative CRT with FOLFOX-4 to identify potential predictors of clinical outcomes...

Rectal cancer is one of the common cancers which poses a threat to the health of mankind. In recent years. Multi-modality treatment strategies for locally advanced rectal cancer improve the treatment efficiency. Accurate prediction of the treatment response after the neoadjuvant chemoradiotherapy (CRT) can guide more suitable treatment strategy. MERCURY study proved the prognostic value of post-CRT standard morphologic MRI(T2-weighted) assessment of tumor regression grade(TRG), and MRI assessment of circumferential resection margin can guide the definitive surgery...

BACKGROUND: Pathologic complete response (pCR) of rectal cancer following neoadjuvant therapy is associated with decreased local recurrence and increased overall survival. This study utilizes a national dataset to identify predictors of pCR in patients with rectal cancer. METHODS: The National Cancer Database was queried for patients with nonmetastatic rectal cancer (2004-2014) who underwent neoadjuvant therapy and surgical resection. Unadjusted associations were assessed using rank-sum tests and χ (2) tests where appropriate...

BACKGROUND/AIMS: Family history of colorectal cancer and tumor location along colon-rectum have been reported as prognostic factors. The aim of the current study is to analyze the role of both on overall survival in a series of patients with metastatic colorectal cancer with synchronous metastases. METHODS: A retrospective mono-institutional analysis has been performed on patients, who received chemotherapy from 2004 to 2008. A Cox proportional-hazards regression was used to calculate hazard ratio (HR) for death, after adjustment for other variables (tumor metastasectomy, number of organs involved with metastases, number of anti-neoplastic drugs, age, sex, tumor grade, baseline CEA)...

BACKGROUND: Preoperative concurrent chemoradiation therapy (CRT) with either capecitabine or 5-florouracil/leucovorin (5 FU/LV) is the standard of care in locally advanced rectal cancer (LARC). Literature comparing the toxicity and response of these two regimens in Indian patients is sparse. Our objective was to compare the pathological response (PR) and clinical outcome of capecitabine versus 5 FU/LV in CRT for LARC. MATERIALS AND METHODS: Sixty patients with LARC treated with preoperative CRT with capecitabine or 5FU/LV from January 2009 to May 2014 were analyzed...

BACKGROUND: Approximately one quarter of patients receiving neoadjuvant chemoradiotherapy (NCRT) for locally advanced rectal cancer will be anemic at presentation. The outcomes of these anemic patients have historically been less favorable. We assessed the potential of anemia to act as an independent biomarker for a poor prognosis in patients with locally advanced rectal cancer. MATERIALS AND METHODS: We performed a retrospective, observational study of consecutive patients with locally advanced rectal adenocarcinoma who underwent NCRT from 2004 to 2009 at 3 English National Health Service trusts...
