INTRODUCTION: Familial Adenomatous Polyposis (FAP) is a hereditary condition characterized by multiple colorectal adenomatous polyps. FAP is the most common adenomatous polyposis syndrome. Restorative proctocolectomy is the most commonly performed surgical procedure performed for patients suffering from FAP with different options for anastomosis, namely ileorectal anastomosis (IRA) or ileal pouch anal anastomosis (IPAA). The occurrence of adenomas is a common finding during follow up and surveillance post surgery for these patients...

Synchronous appearance of the primary gastrointestinal malignancies is rare. Coexistence of primary pancreatic and hepatocellular carcinoma as synchronous malignancy is even rarer. We report a case of such combination in a 50 year old female who presented with bleeding per rectum and while evaluating we found simultaneous appearance of primary malignancies of pancreas, liver and solitary colonic metastasis from the pancreas in the background of chronic calcific pancreatitis. To the best of our knowledge this combination of synchronous pancreatic and hepatocellular carcinoma and colonic metastasis from the pancreas is unique...

BACKGROUND: Colorectal cancers (CRCs) expressing programmed death ligand 1 (PD-L1) have poor prognosis. In the multicohort KEYNOTE-028 trial, the anti-PD-1 antibody pembrolizumab was evaluated in 20 PD-L1-positive advanced solid tumors. Herein, we report results for the advanced CRC cohort. METHODS: Patients with advanced, treatment-resistant PD-L1-positive carcinoma of the colon or rectum were enrolled, regardless of microsatellite instability (MSI) status. Pembrolizumab 10 mg/kg was administered every 2 weeks for up to 2 years or until disease progression/unacceptable toxicity...

The giant condyloma acuminatum or Buschke-Loewenstein tumor is a rare, sexually transmitted disease. It is an epithelial tumor characterized by its high potential of malignancy towards developing into a highly invasive squamous cell carcinoma. The present case concerns a drug addicted 40-year-old man who smuggled drugs using his rectum. He had a partially ulcerated mass in the perianal area of about 20 x 10 cm. He reported a progressive growth of this neoplasm during the last 3 years associated with perianal pain, obstructed defecation, bad sitting posture, no fever and weight loss...

PURPOSE: In selected patients, a wait-and-see strategy after chemoradiotherapy for rectal cancer might be feasible provided that the probability of pathologic complete response (pCR) is high. This study aimed to identify clinical parameters associated with pCR. Furthermore, we attempted to identify subgroups with increased probability of pCR that might aid in clinical decision making. METHODS: A total of 6444 patients that underwent surgical resection of a single primary carcinoma of the rectum after neoadjuvant chemoradiotherapy (nCRT) between January 2009 and December 2016 in the Netherlands were included in the study...

BACKGROUND: The lower part of the digestive tract includes the large intestine, rectum and anus. Treatment algorithms of cancers in these localities have significant differences in both early and advanced stages. The vast majority of metastatic cases are incurable. A few years ago, it was generally accepted that gastrointestinal tumors are poorly immunogenic and modern immunotherapy would not work in gastrointestinal cancers. The breakthrough has become the recognition of the mismatch repair system (MMR) that affects the microsatellite instability (MSI) and its role in the development of colorectal carcinoma (CRC)...

BACKGROUND: Although adenocarcinomas showing neuroendocrine differentiation or those mixed with high-grade neuroendocrine carcinoma (NEC) are sometimes encountered, composite tumors comprising neuroendocrine tumor (NET) Grade 1 and adenocarcinoma are exceedingly rare. CASE PRESENTATION: A 64-year-old male presented after testing positive for fecal occult blood at a medical check-up. A biopsy demonstrated the presence of a NET and endoscopic submucosal dissection was undertaken...

Colorectal carcinoma (CRC) is the third most commonly diagnosed cancer and the third leading cause of cancer death in both men and women in the US. It is mainly a disease of the developed countries with a western culture, yet the disease is not uncommon in developing countries. There is substantial geographical variation in the incidence and demographic characteristics of the disease. Variations are also observed in the risk factors, mode of presentation, sub site distribution and stage of the disease at presentation...

Cystic lymphangiomas are usually congenital malformations of draining lymphatic channels with most common sites including neck, axilla, mediastinum and retroperitoneum. Occurrence of lymphangiomas in scrotum or inguinal region is a rare entity and epididymal origin of these lesions is even more infrequent. We herein report a case of epididymal lymphangioma detected on USG, which developed after surgical abdominal lymph nodal dissection in an adult patient of carcinoma rectum presenting as painless scrotal swelling...

A multitude of proteins are aberrantly expressed in cancer cells, including the oncogenic serine-threonine kinase CK2. In a previous report, we found increases in CK2 transcript expression that could explain the increased CK2 protein levels found in tumors from lung and bronchus, prostate, breast, colon and rectum, ovarian and pancreatic cancers. We also found that, contrary to the current notions about CK2, some CK2 transcripts were downregulated in several cancers. Here, we investigate all other cancers using Oncomine to determine whether they also display significant CK2 transcript dysregulation...

The most important margin in determining the prognosis of rectal cancer is circumferential resection margin (CRM). But, the type of surgery is determined by distal rectal margin (DRM), whether sphincter saving procedure is possible or patient needs an abdominoperineal resection. There are no standardized uniform guidelines for measurement of DRM. The purpose of this study is to assess the distal microscopic spread beyond gross margin after neoadjuvant concurrent chemoradiation (CCRT) in rectal cancers, the factors influencing the distal microscopic spread, the shrinkage of the distal margin in pinned and unpinned fresh and fixed specimen, and to find out the best method of measurement of distal rectal margin...

INTRODUCTION: Fluorouracil (FU)based chemoradiotherapy is regarded as a standard perioperative treatment in locally advanced rectal cancer. Capecitabine is an oral fluoropyrimidine that generates 5FU preferentially at the tumor site by exploiting the higher activity of the enzyme thymidine phosphorylase in tumor tissue compared with healthy tissue. As an oral agent, capecitabine can be administered in the outpatient setting, potentially providing FU exposure similar to a lowdose continuous infusion of 5FU...

Traditionally, doses to the bladder and the rectum were quantified using the bladder and rectal reference points defined by the International Commission on Radiation Units and Measurements (ICRU) in Report No. 38. In this study, we compared the 0.1-, 1.0-, 2.0-cc doses to the bladder and the rectum with the corresponding ICRU point doses using computed tomography (CT)-based planning in the intracavitary brachytherapy of carcinoma of the cervix. CT datasets of 136 consecutive intracavitary brachytherapy insertions between January and May 2015 were analyzed...

Recent studies from our group and many others have shown the ability of histone deacetylase (HDAC) inhibitors for retarding the growth of carcinomas of cervix, colon and rectum in vitro. A search for naturally occurring HDAC inhibitors continues due to the adverse effects associated with known HDAC inhibitors like SAHA and TSA. Therefore in the current study, naturally occurring cinnamic acids derivatives were screened for HDAC inhibitory effect using in silico docking method which identified cinnamic acids as potential candidates...

Most major professional medical organizations advocate universal screening for Lynch syndrome in colorectal carcinoma; however, some allow for a selective screening approach based on clinicopathologic factors including assessment of histologic features of mismatch repair protein deficiency (MMRD). We performed a prospective evaluation for histopathologic features of MMRD in colorectal carcinomas that underwent universal screening for Lynch syndrome to evaluate the ability of histology to predict MMRD. In total, 947 resected colorectal carcinomas over a 5-year period were prospectively analyzed for histologic features of MMRD and for DNA mismatch repair protein abnormalities...

Background: In addition to the presence of neoplasia in the colon and rectum, patients with familial adenomatous polyposis (FAP) may develop numerous polyps and carcinoma within the upper gastrointestinal tract. Methods: The aim of the present paper was to review the incidence advanced duodenal polyposis or cancer and their surgical outcomes. A retrospective review of patients' records from our department was performed. Information was retrieved from a prospective collected data, including clinical (gender, age, family history), endoscopic [association with colorectal cancer (CRC), polyposis severity, age at diagnosis] and surgical management (age, time from the index surgery, type of procedure, morbidity)...

Background: Level of proximal lymphovascular ligation remains controversial in carcinoma rectum. High-tie inferior mesenteric artery (IMA) claims better lymph node clearance; low-tie IMA minimizes autonomic nerve injury (ANI) and ensures vascularity to anastomosis. Objective of this study is to compare postsurgical complications and oncological clearance in laparoscopic rectal resection (LRR) and open rectal resection (ORR) for carcinoma rectum, with low-tie IMA and selective D3 lymphadenectomy...

REVIEW
Kjell Öberg
Intestinal neuroendocrine tumors (NETs) constitute a heterogeneous group with duodenal, small intestinal, colonic and rectal NETs. They constitute more than half of all NETs, with the highest frequencies in the rectum, small intestine, and colon. The tumor biology varies with the location of the primary tumor as well as with the grade and staging of the tumor. Small intestinal NETs usually present low proliferation and are treated in the first line with somatostatin analogs according to current guidelines. If progression occurs, one can add interferon alpha or change the treatment to everolimus...
