Peritoneal cytology as an indicator of peritoneal metastases in colorectal cancer.

J Surg Oncol 2021 May 7. Epub 2021 May 7.

Westat, Rockville, Maryland, USA.

Background: In the management of peritoneal metastases from colon and rectal cancer, the most favorable results are reported with an aggressive combined treatment on patients who have a small extent of the disease. A test to detect occult peritoneal metastases would greatly facilitate the management of this component of colorectal dissemination.

Methods: Currently, the standard test by which to confirm the diagnosis of the peritoneal spread of colorectal cancer is peritoneal cytology. Read More

Differences in Sociodemographic Disparities Between Patients Undergoing Surgery for Advanced Colorectal or Ovarian Cancer.

Ann Surg Oncol 2021 May 6. Epub 2021 May 6.

Department of Surgery, University of Chicago, Chicago, IL, USA.

Background: Cytoreductive surgery (CRS) for ovarian cancer with peritoneal metastases (OPM) is an established treatment, yet access-related racial and socioeconomic disparities are well documented. CRS for colorectal cancer with peritoneal metastases (CRPM) is garnering more widespread acceptance, and it is unknown what disparities exist with regards to access.

Methods: This retrospective cross-sectional multicenter study analyzed medical records from the National Cancer Database from 2010 to 2015. Read More

Hyperthermic Intraperitoneal Chemotherapy for Ovarian and Colorectal Cancer: A Review.

JAMA Oncol 2021 May 6. Epub 2021 May 6.

Center for Gynecologic Oncology Amsterdam, The Netherlands Cancer Institute, Amsterdam.

Importance: The peritoneal surface is a common site of disease in ovarian and colorectal cancer. Peritoneal metastases carry a poor prognosis, despite maximal therapeutic efforts, including surgical removal of tumor deposits and intravenous chemotherapy. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a single intraoperative procedure that delivers chemotherapy directly into the abdominal cavity, leading to high intracellular drug concentration at the peritoneal surface.

Radiomics based on multisequence magnetic resonance imaging for the preoperative prediction of peritoneal metastasis in ovarian cancer.

Eur Radiol 2021 May 4. Epub 2021 May 4.

Radiology Department, Shanxi Medical University Second Affiliated Hospital, Taiyuan, 030001, Shanxi, China.

Objectives: To develop a radiomics signature based on multisequence magnetic resonance imaging (MRI) to preoperatively predict peritoneal metastasis (PM) in ovarian cancer (OC).

Methods: Eighty-nine patients with OC were divided into a training cohort including patients (n = 54) with a single lesion and a validation cohort including patients (n = 35) with bilateral lesions. Radiomics features were extracted from the T2-weighted images (T2WIs), fat-suppressed T2WIs, multi-b-value diffusion-weighted images (DWIs), and corresponding parametric maps. Read More

Crystal-storing histiocytes in ascites leading to a diagnosis of plasma cell myeloma.

Diagn Cytopathol 2021 May 4. Epub 2021 May 4.

Department of Pathology, Wake Forest Baptist Health, Winston-Salem, North Carolina, USA.

Histiocytes containing multiple needle-shaped eosinophilic crystals visualized in a peritoneal fluid sample during evaluation of a patient for liver transplantation led to the diagnosis of unsuspected IgA kappa myeloma. Crystal-storing histiocytosis is a rare phenomenon typically associated with multiple myeloma and B-cell lymphoproliferative disorders. It can involve almost any anatomic site and can occasionally be seen in body fluid samples. Read More

Targeted dual inhibition of c-Met/VEGFR2 signalling by foretinib improves antitumour effects of nanoparticle paclitaxel in gastric cancer models.

J Cell Mol Med 2021 May 3. Epub 2021 May 3.

Department of Surgery, Indiana University School of Medicine, South Bend, IN, USA.

Elevated expression of multiple growth factors and receptors including c-Met and VEGFR has been reported in gastric adenocarcinoma (GAC) and thus provides a potentially useful therapeutic target. The therapeutic efficacy of foretinib, a c-Met/VEGFR2 inhibitor, was determined in combination with nanoparticle paclitaxel (NPT) in GAC. Animal studies were conducted in NOD/SCID mice in subcutaneous and peritoneal dissemination xenografts. Read More

Bispecific T-Cell Engaging Antibodies Against MUC16 Demonstrate Efficacy Against Ovarian Cancer in Monotherapy and in Combination With PD-1 and VEGF Inhibition.

Front Immunol 2021 14;12:663379. Epub 2021 Apr 14.

Division of Hematology-Oncology, Massachusetts General Hospital, Boston, MA, United States.

Immunotherapy for ovarian cancer is an area of intense investigation since the majority of women with relapsed disease develop resistance to conventional cytotoxic therapy. The paucity of safe and validated target antigens has limited the development of clinically relevant antibody-based immunotherapeutics for this disease. Although MUC16 expression is almost universal in High Grade Serous Ovarian Cancers, engagement of the shed circulating MUC16 antigen (CA-125) presents a theoretical risk of systemic activation and toxicity.

Different risk factors for three major recurrence patterns of pathological stage II or III gastric cancer patients who completed adjuvant S-1 monotherapy.

Eur J Surg Oncol 2021 Apr 21. Epub 2021 Apr 21.

Department of Gastroenterological Surgery, Gastroenterological Center, Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan.

Introduction: After curative gastrectomy followed by 1-year adjuvant S-1 monotherapy for pathological stage (pStage) II or III gastric cancer, some patients experience peritoneal, hematogenous, or lymph nodal recurrence. However, risk factors for each recurrence pattern despite completed adjuvant S-1 monotherapy remain unclear. The aim of this study was to determine which factors influence each recurrence type after curative gastrectomy followed by 1-year adjuvant S-1 monotherapy. Read More

Feasibility of Non-Exposure Simple Suturing Endoscopic Full-Thickness Resection in Comparison with Laparoscopic Endoscopic Cooperative Surgery for Gastric Subepithelial Tumors: Results of Two Independent Prospective Trials.

Cancers (Basel) 2021 Apr 13;13(8). Epub 2021 Apr 13.

Center for Gastric Cancer, National Cancer Center, 323 Ilsan-ro, Goyang 10408, Korea.

Recently, nonexposure simple suturing endoscopic full-thickness resection (NESS-EFTR) method was developed to avoid tumor exposure to the peritoneal cavity. The aim of this study is to compare the short-term outcomes of the NESS-EFTR method with those of laparoscopic and endoscopic cooperative surgery (LECS) for gastric subepithelial tumors (SETs). A prospective single-center trial of LECS for gastric SETs was performed from March 2012 to October 2013 with a separate prospective trial of NESS-EFTR performed from August 2015 to June 2017, enrolling 15 patients each.
