Preoperative chemoradiotherapy (PCRT) is a standard treatment for locally advanced rectal cancer. The influence of PCRT on anorectal function has not been objectively assessed. We evaluated the short-term influence of PCRT on anorectal function in patients with locally advanced rectal cancer using anorectal manometry. We included 310 patients with locally advanced mid and lower rectal cancer wh...
زمینه و هدف: لیشمانیا اینفانتوم به عنوان عامل لیشمانیوز احشایی است. لیشمانیا اینفانتوم براساس تعداد معدود تایپ ایزوآنزیم از انسانها و سگها در منطقه کلیبر با وفور بالا دیده شده ولی تاکنون درباره آلودگی لیشمانیایی پشه خاکیهای ناقل بیماری گزارشی منتشر نشده است. لذا این مطالعه با هدف تعیین آلودگی پشه خاکی های ناقل بیماری در منطقه انجام شد. روش کار: پشه خاکیها با تلههای چسبان و نورانی صید گرد...
The present study explored the benefit of preoperative chemoradiotherapy (PCRT) for sphincter preservation in locally advanced low-lying rectal cancer patients who underwent stapled anastomosis, especially in those with deep and narrow pelvises determined by magnetic resonance imaging.Patients with locally advanced low-lying rectal cancer (≤5 cm from the anal verge) who underwent stapled anasto...
BACKGROUND To construct a short prostate cancer radiation late toxicity (PCRT) questionnaire with health-related quality-of-life (HRQoL) domains. METHODS The PCRT was developed by item generation, questionnaire construction (n = 7 experts, n = 8 focus group patients), pilot testing (n = 37), item reduction (n = 100), reliability testing (n = 237), and validity testing (n = 274). RESULTS Rel...
We examined whether serum protein profiling is a reliable index for prediction of therapeutic efficacy of preoperative chemoradiotherapy (PCRT) in advanced esophageal cancer compared with evaluation of the efficacy of conventional clinical examination. We entered 42 patients who received PCRT and surgery between 1998 and 2002 into this study. Serum protein profiling was performed using the preo...
We compared the oncological outcomes of sphincter-saving resection (SSR) and abdominoperineal resection (APR) in 409 consecutive patients with very low rectal cancer (i.e., tumors within 3 cm from the anal verge); 335 (81.9%) patients underwent APR and 74 (18.1%) underwent SSR. The APR group comprised higher proportions of men (67.5% vs 55.4%, P = .049) and advanced-stage patients (P < .001). P...
The aim of this study was to evaluate the pathologic responses and changes to surgical strategies following preoperative chemoradiotherapy (PCRT) in rectal cancer patients according to their clinical T stage (cT).The use of PCRT has recently been extended to less advanced disease.The authors enrolled 650 patients with cT2 to 4 mid and low rectal cancer who received both PCRT and surgical resect...
PURPOSE Previous studies have demonstrated the prognostic impact of the prognostic nutritional index (PNI), a proposed indicator of immunonutritional statuses of surgical patients, on patients with various gastrointestinal cancers. Although the prognostic impact of the PNI on patients with colorectal cancer has been well established, its value has not been studied in patients treated with preop...
PURPOSE To determine whether the tumor immune infiltrate, as recently evaluated with the Immunoscore methodology, could be a useful prognostic marker in patients with rectal cancers. EXPERIMENTAL DESIGN The influence of the immune infiltrate on patient's outcome was investigated in patients with or without preoperative chemoradiation therapy (pCRT). The density of total (CD3(+)) and cytotoxic...
PURPOSE To evaluate the feasibility of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) for preoperative concurrent chemoradiotherapy (PCRT) in locally advanced rectal cancer (LARC), by comparing with 3-dimensional conformal radiotherapy (3D-CRT). MATERIALS AND METHODS Patients who were treated with PCRT for LARC from 2015 January to 2016 December were retrospectively...
