BACKGROUND: Renal cell carcinoma metastasizing to rectum is very rare, and the unusual metastatic sites should be paid attention to during the follow-up of renal cell carcinoma. CASE SUMMARY: We describe a case of a 65-year-old male who was diagnosed with metastatic renal cell carcinoma to rectum 10 years after the right radical nephrectomy. Histopathology and immunohistochemical examinations contribute to making differential diagnosis between rectal metastasis of renal cell carcinoma and primary rectal clear cell carcinoma...

OBJECTIVE: To determine whether diffusion-weighted imaging (DWI) can be used for quantitatively evaluating severity of acute radiation proctopathy after radiotherapy for cervical carcinoma. MATERIALS AND METHODS: One hundred and twenty-four patients with cervical carcinoma underwent MR examination including DWI before and after radiotherapy. Acute radiation proctopathy was classified into three groups (grade 0, grade I-II and grade III-IV) according to Toxicity Criteria of the Radiation Therapy Oncology Group (RTOG)...

BACKGROUND: This is an update of the Cochrane review published in 2002.Colorectal cancer (CRC) is a major cause of morbidity and mortality in industrialised countries. Experimental evidence has supported the hypothesis that dietary fibre may protect against the development of CRC, although epidemiologic data have been inconclusive. OBJECTIVES: To assess the effect of dietary fibre on the recurrence of colorectal adenomatous polyps in people with a known history of adenomatous polyps and on the incidence of CRC compared to placebo...

Extramammary Paget's disease (EMPD) is a rare disease which is found in apocrine-rich locations such as anogenital region, axilla and rarely in other sites. Perianal EMPD is often reported as the involvement of perianal skin, but involvement of anal mucosa is very rare. Based on pathogenesis and association with either synchronous or metachronous malignancy, EMPD can be divided into primary and secondary types. Treatment approach for these two types of Paget's disease and their prognosis is different, thus it is important to make the distinction...

BACKGROUND AND AIM: The manner in which colorectal lesions are being detected with PillCam COLON2 capsule endoscopy (CCE2) has markedly improved in recent days. However, limited data are available on CCE2 for detecting laterally spreading tumors (LSTs). The aim of this study was to compare CCE2 with optical colonoscopy (OC), which is currently the gold standard used in the detection of LSTs. METHODS: We performed a prospective, single-academic center study comparing CCE2 with OC in patients with LSTs diagnosed using OC, which was performed during the 3-month period prior to CCE2...

PURPOSE: Cylindrical applicators are often used for postoperative HDRbrachytherapy in endometrial carcinoma. It has been considered that dosimetric variation between fractions for this treatment is minimal and might not be necessary to perform treatment planning for every fractions. At our institute, it is traditional to perform treatment planning with CT simulation on the first fraction and uses this plan for the rest of treatment. This study was aim to evaluate the errors of critical structure doses between the fractions when simulation and planning were done for first fraction only...

PURPOSE: In this study, IMRT optimization based on biological related models were applied in the clinic for cervical carcinoma cases and the results were compared with the traditional physical optimization. METHODS: Twenty patients of advanced stage cervical carcinoma were selected in this study. The treatment plan was generated on each patient using both biological and physical optimized model respectively. Additionally, the biological optimization was based on two basic models for bladder and rectum: Poisson (adjustable parameters: alpha/beta, gamma, D50) and Lyman-Kutcher-Burman (adjustable parameters: m, n, D50)...

PURPOSE: WHO GLOBOCAN 2012 data showed that Australia and New Zealand have the highest incidence rates of colorectal cancer in the world (Ferlay et al. 1). Current guidelines recommend that patients admitted for an episode of acute diverticulitis require an early follow-up colonoscopy to rule out colorectal malignancy as reported by Fozard et al. (Colorectal Dis 13:1-11, 2011). Recent studies however have indicated that this may not be warranted (Brar et al. Dis Colon rectum 56:1259-1264, 2013)...

PURPOSE: To evaluate the preliminary results of vaginal-cuff relapses (VCR) and complications of a short brachytherapy (BT) schedule in postoperative endometrial carcinoma. METHODS AND MATERIALS: From September 2011 to December 2014, 102 patients were treated with postoperative BT for endometrial carcinoma. Seventy-four patients received a single 7 Gy dose after external beam irradiation (Group 1), and 28 intermediate-risk patients received three daily fractions of 6 Gy (Group 2)...

OBJECTIVE: Present long-term outcomes in primary cervical cancer treated with external beam and high dose rate interstitial brachytherapy. METHODS: High dose rate (HDR) interstitial (IS) brachytherapy (BT) and external beam (EBRT) were administered from 1992 to 2009 to 315 patients who were unsuitable for intracavitary (IC) BT alone. Histology was 89% squamous cell, 8% adenocarcinoma, and 3% adenosquamous. FIGO stage was I-14%, II-47%, III-34%, and IVA-5%. Median tumor size was 6cm...

BACKGROUND: Growing evidence supports the notion that the onset of tumorigenesis could occur through cancer stem cells (CSCs). These tumour cells show low proliferative rates, high self-renewal capacity, propensity to differentiate into active proliferating tumour cells & resistance to chemoradiotherapy thus, possibly causing local recurrences & metastasis formation. CD44 has been used as a marker to isolate CSCs from colorectal carcinoma (CRC). AIM: To investigate the immunohistochemical expression of cancer stem cells marker (CD44) in CRC and correlate its expression with the clinicopathological aspects, TNM staging and modified Dukes' classification...

CASE DESCRIPTION 5 dogs between 9 and 11 years of age were evaluated for treatment of primary (n = 2) or metastatic (3) hepatic neoplasia. CLINICAL FINDINGS Patients were evaluated on an elective (n = 3) or emergency (2) basis. Two dogs with primary hepatic neoplasia were evaluated because of lethargy and inappetence. One dog was referred after an enlarged anal sac was detected via palpation per rectum during a routine physical examination. Two dogs were evaluated on an emergency basis because of lethargy and weakness, and hemoabdomen in the absence of a history of trauma was detected...

INTRODUCTION: The very first TEM (transanal endoscopyc microsurgery) in Hungary was performed in our department by professor Attila Nagy in 1992. Up to August 2016, 1385 operation in total was performed with an average number of 60 per year., 992 operations were carried out for benign reasons and 393 cases for malignancies. We analyze the malignant cases operated by TEM in 2013. SUBJECTS AND METHODS: In 2013 we performed 121 TEM on 118 patients (in 3 cases twice)...

Carcinomas are rare tumors of the adolescent-young adult (AYA) with a different spectrum from those of adults. The most common sites outside of the thyroid is the nasopharynx, salivary gland, colon-rectum and ovaries. If nasopharyngeal carcinoma or salivary gland tumors are good prognosis, others are more reserved prognosis, such as digestive carcinomas, gynecological or midline. The revelation modes are non-specific and depend on the location: mass, tumor syndrome, pain, impaired general condition. The unusual of pediatric carcinomas led to propose a systematic oncogenetic exploration...

Heterotopic ossification in colorectal carcinoma is extremely rare. This report presents the case of a 57-year-old male who had undergone a low anterior resection following a diagnosis of rectal carcinoma. Histological examination showed heterotopic ossification in the tumor. The patient was referred to Ibaraki Medical Center, Tokyo Medical University, with a diagnosis of rectal carcinoma by a local physician. Abdominal computed tomography revealed thickening of the rectal wall with calcified deposits, and virtual colonoscopy showed stenosis with a mass in the rectum...
