Introduction And Importance: Disseminated peritoneal leiomyomatosis (DPL) is a rare benign disease, characterized by intraperitoneal dissemination of smooth-muscle tumor masses.
Case Presentation: The patient, a 40-year-old, female - presented with complaints of periodic back pain. During the initial workup, a tumor mass was visualized in the pelvis on ultrasound. Further clinical workup included computer tomography (CT) scan and ultrasound-guided fine-needle biopsy. A tumor mass in the right adrenal gland was identified on CT. Pathological examination revealed no signs of malignancy. The multidisciplinary team decided on surgical treatment. Tumor masses were removed from the pelvic cavity, the anterior abdominal wall, and the projection of the right adrenal gland with preservation of the uterus and ovaries due to the patient's wishes. Pathological examination with immunohistochemistry of surgical specimen confirmed diagnosis of DPL.
Clinical Discussion: Due to the rarity of DPL there are no standard guidelines for diagnostics and treatment. In many cases, on initial workup, DPL may look like a malignant tumor with intraperitoneal spread, which may lead to an inappropriate choice of treatment.
Conclusion: Differential diagnosis of DPL may be a challenge due to its appearance as a disseminated peritoneal malignancy on CT scans and at laparotomy. A multidisciplinary approach is key to choosing the right clinical course for such patients.

Neutrophil extracellular traps promote pre-metastatic niche formation in the omentum by expanding innate-like B cells that express IL-10.

Disseminated cancer cells in the peritoneal fluid often colonize omental fat-associated lymphoid clusters but the mechanisms are unclear. Here, we identify that innate-like B cells accumulate in the omentum of mice and women with early-stage ovarian cancer concomitantly with the extrusion of chromatin fibers by neutrophils called neutrophil extracellular traps (NETs). Studies using genetically modified NET-deficient mice, pharmacologic inhibition of NETs, and adoptive B cell transfer show that NETs induce expression of the chemoattractant CXCL13 in the pre-metastatic omentum, stimulating recruitment of peritoneal innate-like B cells that in turn promote expansion of regulatory T cells and omental metastasis through producing interleukin (IL)-10.

Background: This study aims to evaluate the postoperative safety, long-term survival, and postoperative peritoneal metastases (PPM) rate associated with laparoscopic surgery (LS) for T4 colon cancer.
Materials And Methods: After propensity score matching, there were 68 patients in each of the LS and Open surgery groups. The primary outcomes were the 3-year OS, DFS, and PPM rates.

Article Synopsis
- Pseudomyxoma peritonei (PMP) is a rare condition linked to mucin-producing tumors, usually starting in the appendix, leading to mucin buildup in the abdomen.
- Researchers conducted RNA-seq analysis on ten PMP cases and their healthy tissue to reveal 32 differently expressed genes, indicating that PMP tumors arise from goblet cells.
- The study found significant associations between PMP tumors and important biological processes like epithelial-mesenchymal transition, angiogenesis, and inflammation, with further analysis highlighting distinct gene expressions in different PMP types, suggesting more aggressive traits in peritoneal mucinous adenocarcinomas (PMCA).
Development of a Prognostic Model for Stage IV Colorectal Cancer Using Metastatic Patterns.

Department of Minimally Invasive Surgical and Medical Oncology, Fukushima Medical University, Koriyama, Japan.
Background/aim: Metastatic patterns are the most convenient and common prediction models for the prognosis of patients with stage IV colorectal cancer. However, current prediction models do not include the severity of metastases in organs and exclude certain types of metastatic patterns. The aim of this study was to develop a prediction model that included several metastatic organs as well as the severity of liver and lung metastases, based on the Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma: the 3 English Edition.

A satisfactory treatment for the dissemination of duodenal cancer has not yet been established. We describe a case of peritoneal dissemination and malignant ascites in duodenal cancer that was successfully treated with adoptive cell therapy with no adverse effects. A 72-year-old Japanese male patient with primary duodenal cancer with distal lymph node metastases received chemotherapy with S-1, an oral pyrimidine fluoridederived agent, and oxaliplatin after gastrojejunal bypass, which resulted in tumor shrinkage; however, peritoneal dissemination developed.
