Peritoneal Carcinomatosis of Colorectal Origin in Cyclosporine Immunosuppressed Rats.

Gulf J Oncolog 2020 May;1(33):27-30

Surgical Research Laboratory, Saint Joseph University, Beirut, Lebanon.

Objective: We evaluate the seeding step of peritoneal carcinomatosis cancer as a surrogate for the role of the omentum in colorectal tumors.

Ultrasonographic findings and diagnosis of omental dedifferentiated liposarcoma: a case report.

J Rural Med 2020 Apr 1;15(2):68-72. Epub 2020 Apr 1.

Department of Gastroenterology, Gifu University Graduate School of Medicine, Japan.

Liposarcoma is one of the most common types of soft tissue sarcomas and can develop at any site, although omental liposarcoma is extremely rare. Omental liposarcoma has a poor prognosis because the diagnosis is difficult, until it presents as a large tumor causing severe noticeable clinical symptoms. A 51-year-old male with lower abdominal pain was referred to our clinic. Read More

Roles of omental and bone marrow adipocytes in tumor biology.

Adipocyte 2019 12;8(1):304-317

a Department of Pathology, Yonsei University College of Medicine , Seoul , South Korea.

Accumulating evidence highlights the importance of interactions between tumour cells and stromal cells for tumour initiation, progression, and metastasis. In tumours that contain adipocyte in their stroma, adipocytes contribute to modification of tumour microenvironment and affect metabolism of tumour and tumour progression by production of cytokines and adipokines from the lipids. The omentum and bone marrow (BM) are highly adipocyte-rich and are also common metastatic and primary tumour developmental sites. Read More

Measuring response to neoadjuvant chemotherapy in high-grade serous tubo-ovarian carcinoma: an analysis of the correlation between CT imaging and chemotherapy response score.

Int J Gynecol Cancer 2019 May 15. Epub 2019 May 15.

Oncology, Bendat Family Comprehensive Cancer Centre, St John of God Hospital, Subiaco, Subiaco, Western Australia, Australia.

Introduction: Response to neoadjuvant chemotherapy is measured by CT and the decision to proceed with interval surgery is made on the radiological response after two or three cycles of therapy. The Chemotherapy Response Score grades histological tumor regression in omental metastases resected at interval surgery and is associated with progression-free survival and overall survival. It is uncertain whether radiological response is associated with prognosis and whether radiological response predicts Chemotherapy Response Score. Read More

The Challenge of Evaluating Adnexal Masses in Patients With Breast Cancer.

Clin Breast Cancer 2018 08 12;18(4):e587-e594. Epub 2018 Mar 12.

Instituto Nacional de Câncer (INCA), Rio de Janeiro, Brazil. Electronic address:

This narrative literature review addresses the problem of an adnexal mass discovered during the course of breast cancer (BC) care, which may represent a benign condition, a metastatic process, or a primary ovarian cancer (OC), clinical scenarios associated with distinct physiopathology and prognosis. Furthermore, the coexistence of BC and OC in the same patient may be owing to a hereditary disorder, deserving specific management strategies and counseling. The initial detection and evaluation of an adnexal mass in a patient with BC requires a high index of suspicion, and the initial workup should include a thorough medical history and physical examination, measurement of tumor markers, complete blood count, and imaging tests.

Distinct preoperative clinical features predict four histopathological subtypes of high-grade serous carcinoma of the ovary, fallopian tube, and peritoneum.

BMC Cancer 2017 Aug 29;17(1):580. Epub 2017 Aug 29.

Department of Gynecology and Obstetrics, Kyoto University, 54 Kawahara-cho, Shogoin, Sakyo-ku, Kyoto, 606-8507, Japan.

Background: The Cancer Genome Atlas Research Network reported that high-grade serous carcinoma (HGSC) can be classified based on gene expression profiles into four subtypes, termed "immunoreactive," "differentiated," "proliferative," and "mesenchymal." We previously established a novel histopathological classification of HGSC, corresponding to the gene expression subtypes: immune reactive (IR), papillo-glandular (PG), solid and proliferative (SP), and mesenchymal transition (MT). The purpose of this study is to identify distinct clinical findings among the four pathological subtypes of HGSC, as well as to predict pathological subtype based on preoperative images. Read More

Extremely Locally Advanced Ovarian Malignant Mixed Mullerian Tumor in 37-Years-Old Female.

Pril (Makedon Akad Nauk Umet Odd Med Nauki) 2017 Mar;38(1):75-79

General Hospital Kumanovo, Kumanovo.

Ovarian carcinosarcomas, rare variant of ovarian carcinoma, composed of both carcinomatous and mesenchymal components, solid and/or cystic, fleshy and hemorrhagic, frequently spreading beyond the ovary, are treated with surgery and adjuvant chemotherapy according to the treatment principles of ovarian carcinomas due to the small number of reported cases and lack of randomized studies. We report a case of a 37-year-old woman with clinical signs of extremely locally advanced tumor of ovarian origin, infiltrating the lower left quadrant of the abdominal wall with necrosis of the covering skin. Prior biopsy of the left ovary and omentum confirmed poorly differentiated serous adenocarcinoma. Read More

GEIS guidelines for gastrointestinal sarcomas (GIST).

Cancer Treat Rev 2017 Apr 2;55:107-119. Epub 2017 Mar 2.

Hospital Virgen del Rocío, Av Manuel Siurot s/n, 41013 Sevilla, Spain.

Gastrointestinal stromal sarcomas (GISTs) are the most common mesenchymal tumours originating in the digestive tract. They have a characteristic morphology, are generally positive for CD117 (c-kit) and are primarily caused by activating mutations in the KIT or PDGFRA genes(1). On rare occasions, they occur in extravisceral locations such as the omentum, mesentery, pelvis and retroperitoneum. Read More

Intraindividual genomic heterogeneity of high-grade serous carcinoma of the ovary and clinical utility of ascitic cancer cells for mutation profiling.

J Pathol 2017 Jan 21;241(1):57-66. Epub 2016 Nov 21.

Department of Pathology, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

Intraindividual tumoural heterogeneity (ITH) is a hallmark of solid tumours and impedes accurate genomic diagnosis and selection of proper therapy. The aim of this study was to identify ITH of ovarian high-grade serous carcinomas (OSCs) and to determine the utility of ascitic cancer cells as a resource for mutation profiling in spite of ITH. We performed whole-exome sequencing, copy number profiling and DNA methylation profiling of four OSC genomes by using multiregional biopsies from 13 intraovarian lesions, 12 extraovarian tumour lesions (omentum/peritoneum), and ascitic cells.
