Diagnosis of portal vein tumor thrombosis in colorectal carcinoma in fluorodeoxyglucose positron emission tomography-computed tomography scan and its clinical implication.

Digish Shah

World J Nucl Med 2020 Jul-Sep;19(3):296-300. Epub 2020 Jul 22.

Nuclear Medicine and PET CT Department, HCG Cancer Hospital, Ahmedabad, Gujarat, India.

Hypercoagulable state is seldom associated with colorectal carcinoma either in the form of bland thrombosis or tumor thrombosis (TT). Venous TT should not be overlooked while deciding treatment of colorectal cancer due to its propensity to complicate the disease in terms of morbidity and mortality even in favorable prognostic case of colorectal cancer. Fluorodeoxyglucose positron emission tomography-contrast-enhanced computed tomography (FDG PET-CECT) scan has proven its role in staging of colorectal cancer and also to diagnose tumor venous thrombosis.

MLH1 promoter hypermethylation: are you absolutely sure about the absence of MLH1 germline mutation? About a new case.

Fam Cancer 2020 01 19;19(1):11-14. Epub 2019 Nov 19.

Centre Léon Bérard, Cancer Genomics Platform, 69272, Lyon cedex 08, France.

Lynch syndrome accounts for 3-5% of colorectal cancers and is due to a germline mutation in one of the mismatch repair genes MLH1, MSH2, MSH6, and PMS2. Somatic hypermethylation of the MLH1 promoter is commonly associated to sporadic cases. Strategies have been developed to identify patients with Lynch Syndrome based on clinical findings, tumoral phenotype, family history and immunohistochemistry analysis. Read More

Transanal total mesorectal excision of giant villous tumor of the lower rectum with McKittrick-Wheelock syndrome: a case report of a novel surgical approach.

Surg Case Rep 2019 Nov 6;5(1):173. Epub 2019 Nov 6.

Department of Colorectal Surgery, National Cancer Center Hospital East, 6-5-1 Kashiwanoha, Kashiwa-shi, Chiba-ken, 277-8577, Japan.

Background: McKittrick-Wheelock syndrome (MKWS) is caused by a villous tumor of the rectosigmoid colon with hypersecretion of mucus containing electrolytes. Complete resection of the tumor is needed to cure this disease. Transanal total mesorectal excision (TaTME) is currently a promising treatment for lower rectal tumor because of the reliability of its resection margin especially in bulky tumor. Read More

Modified posterior pelvic exenteration with pelvic side-wall resection requiring both intestinal and urinary reconstruction during surgery for ovarian cancer.

Gynecol Oncol 2019 10 25;155(1):172-173. Epub 2019 Jul 25.

Department of Gynecology, Cancer Institute Hospital, 3-8-31 Ariake, Koutou-ku, Tokyo 135-8550, Japan.

Objective: Because of the anatomic proximity of the rectosigmoid to the female pelvic organs and its frequent involvement in ovarian cancer, an en bloc resection of ovarian tumors together with the uterus and rectosigmoid, also known as a modified posterior pelvic exenteration (MPPE), is frequently performed to achieve optimal cytoreduction [1]. Additionally, if the tumor has infiltrated the pelvic side-wall, a MPPE combined with pelvic side-wall resection can be selected [2]. We report the details of a technique for this surgery requiring intestinal and urinary reconstruction. Read More

Intramucosal poorly differentiated and signet-ring cell components in patients with ulcerative colitis-associated high-grade dysplasia.

Dig Endosc 2019 Nov 22;31(6):706-711. Epub 2019 Aug 22.

Division of Gastroenterology and Hepatology, Department of Internal Medicine, Keio University School of Medicine, Tokyo, Japan.

Despite the rarity of colorectal poorly differentiated adenocarcinoma (Por) and signet-ring cell carcinoma (Sig), they are more frequent in patients with ulcerative colitis (UC). However, little is known about these components of early colitis-associated cancer due to the difficulty of detection at an early stage. Here, we reviewed colitis-associated high-grade dysplasia/cancer with Por/Sig components within the submucosa among 103 lesions of 79 UC patients who presented between 1997 and 2017. Read More
