Carmen Jochem, Michael Leitzmann
There is strong evidence that modifiable lifestyle factors such as obesity play a key role in colorectal carcinogenesis. Epidemiologic data have consistently reported a positive association between obesity and colorectal cancer. The relative risk associated with general obesity (as assessed by BMI) is higher in men than in women and for cancer of the colon than for cancer of the rectum. Abdominal obesity (as assessed by waist circumference (WC) or waist-to-hip ratio) is associated with an increased risk of colorectal cancer in both sexes, with stronger associations for cancer of the colon than for cancer of the rectum...

For over a decade, excess body weight, commonly categorized as overweight (body mass index, BMI: 25.0 to 29.9 kg/m2) and obesity (BMI: ≥ 30 kg/m2) has been an established incidence risk factor for several adult cancers (1). For 2012, the burden of disease attributed to elevated BMI was estimated as nearly half-million new cancers worldwide, making this the third highest ranked cancer risk factor globally after smoking and infections (ranked second in most western populations) and an important public health problem (2, 3)...

PURPOSE: To elucidate potential risk factors important for the appearance of late rectal toxicity (LRT) after high-dose-rate boost treatment (HDRBT) of prostate cancer and to validate the predictive value of the minimal dose to the most exposed 2 cc of rectum received with HDRBT (D2ccrect). METHODS AND MATERIALS: The study of LRT, defined as relative deterioration of defecation problems (RDDP) (stool frequency, pain, rectal bleeding, fecal urgency, and incontinence) during follow-up period, was carried out on 88 patients, consecutively treated from October 2006 through April 2011 with HDRBT of 3 × 6-7 Gy to 50-50...

PURPOSE: Prostate brachytherapy is an important treatment technique for patients with localized prostate cancer. An inflatable rectal ultrasound probe cover is frequently utilized during the procedure to adjust for unfavorable prostate position relative to the implant grid. However, the inflated cover causes prostate deformation, which is not accounted for during dosimetric planning. Most of the therapeutic dose is delivered after the procedure when the prostate and surrounding organs-at-risk are less deformed...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with continuous or recurrent symptoms. A 42-year-old male patient with intermittent diarrhea accompanied by bloody mucopurulent stools was admitted to our hospital. The diagnosis of UC was confirmed by a combination of laboratory examination, colonoscopy, and histological assay. The patient developed herpes zoster in the hospital, which challenged traditional treatments. Therefore, we performed an autologous bone marrow cells to modulate the immune system with his permission...

Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases (PubMed and EMBASE) using the key words "rectum", "rectal", "cancer", "laparoscopy", "robot"...

Peritoneal dissemination (PD) of cancer is difficult to diagnose. Previous reports have shown that carbohydrate antigen 125 (CA125) is a sensitive marker of PD of gastric cancer. However, CA125 has not been evaluated as a marker of colorectal cancer (CRC), and its accuracy in men is controversial. The aim of this study was to compare the ability of CA125 and carcinoembryonic antigen (CEA) to predict PD of CRC in men and women.Preoperative CA125 and CEA concentrations were measured in 853 people (510 men, 343 women) over 10 years...

Colorectal cancer is the third most common cancer. Approximately 20% of patients have at the time of presentation metastasized colorectal cancer, which is incurable in ~80% of cases. The present case report describes a typical case diagnosed with an advanced invasive colorectal adenocarcinoma, with two suspect hypodense lesions in the liver, as revealed by sonography. Judged inoperable for a curative outcome by radical resection, the patient was treated with a novel surgical technique based on stimulating the immune system, termed 'autologous tumor immunizing devascularization' (ATID)...

INTRODUCTION: There are 11 500 rectal cancers diagnosed annually in the UK. Although surgery remains the primary treatment, there is evidence that preoperative radiotherapy (RT) improves local recurrence rates. High-quality surgery in rectal cancer is equally important in minimising local recurrence. Advances in MRI-guided prediction of resection margin status and improvements in abdominoperineal excision of the rectum (APER) technique supports a reassessment of the contribution of preoperative RT...
