Study Objective: Although hysteroscopy (HSC) can be used for assessing the uterine cavity in women with suspected endometrial cancer (EC), it remains controversial as a procedure because it can potentially enhance the metastatic spread of cancer cells. Moreover, it is important to assess this hypothesis for type II EC, a more aggressive phenotype that usually presents with endometrial atrophy and has worse prognosis. Thus, we aimed to assess the prevalence of positive peritoneal cytology result in women with type II EC who underwent HSC as a diagnostic tool and to determine the factors associated with patient relapse/survival.
Design: Retrospective cohort analysis (2002-2017).
Setting: Tertiary, academic hospital.
Patients: One hundred twenty-seven women with type II EC.
Interventions: Diagnostic HSC (HSC) (n = 43) or dilation/curettage (D&C) (n = 84).
Measurements And Main Results: Primary end point was the frequency of positive peritoneal cytology result. Survival curves were projected using the Kaplan-Meier method and compared using the log-rank test. Cox regression analysis with hazard ratio (HR) and 95% confidence intervals (CIs) were calculated to assess the factors related with the disease-free survival (DFS) and the disease-specific survival (DSS). Advanced cancer stage and greater vascular invasion appeared more frequently in the D&C group (p = .008 and p = .04, respectively). Positive peritoneal cytology result was present in 2 of 43 (4.6%) women following HSC and in 9 of 84 (10.7%) following D&C (p = .22). DFS and DSS curves did not statistically differ between the groups. Multivariate analysis for DFS revealed that advanced cancer stage (III and IV) (HR = 4.67; 95% CI, 2.34-9.34; p <.001) and advanced age (HR = 1.08; 95% CI, 1.04-1.13]; p <.001) were the factors associated with relapse. For DSS, advanced age (HR = 1.08; 95% CI, 1.05-1.12; p <.001), cancer stage III/IV (HR = 3.95; 95% CI, 2.18-7.15; p <.001), and vascular invasion (HR = 2.47; 95% CI, 1.34-4.54; p = .004) increased the risk of mortality.
Conclusion: Diagnostic HSC did not increase the rate of positive peritoneal cytology result at the time of surgical staging in this cohort of women with type II EC and is probably as safe as D&C.

Objectives: Although curative resection for synchronous peritoneal carcinomatosis has been reported to improve prognosis, cases with positive intraoperative lavage cytology have not been reported. In this study, we investigated the prognostic value of potentially curative resection based on colorectal cancer and lavage cytology positivity in patients with synchronous peritoneal carcinomatosis.
Methods: We retrospectively evaluated 72 patients who underwent intraoperative lavage cytology and one-stage potentially curative resection of primary and metastatic lesions (lavage cytology-positive, n = 21; lavage cytology-negative, n = 51) between July 2004 and December 2019.

Granulocyte colony stimulating factor (G-CSF) has been shown in mammalia to activate a series of signal transduction systems and exert various biological effects, such as controlling the differentiation, proliferation, and survival of granulocytes, promoting the movement of hematopoietic stem cells from the bone marrow to the bloodstream, and triggering the development of T cells, dendritic cells, and immune tolerance in transplants. In this study, the mRNA of flounder G-CSF (PoG-CSF) and its receptor (PoGCSFR) were detected and widely expressed in all examined tissues with the highest expression in peritoneal cells. G-CSF and GCSFR cells were observed to be abundantly distributed in the leukocytes from the peritoneal cavity, followed by head kidney.

Although peritonitis is highly prevalent in cattle, there have been only limited studies on the pathology of this condition. We describe the gross and histological aspects of primary and secondary peritonitis in cattle based on necropsy reports of 46 cases. Twenty-six were female (26/46; 56.

Objective: Our retrospective study aimed to investigate the role of computed tomography (CT) using both the tomographic Fagotti index and the Sugarbaker peritoneal cancer index (PCI) in predicting the feasibility of optimal interval debulking surgery in epithelial ovarian cancer.
Methods: Patients with advanced ovarian cancer treated in our institution who were eligible for interval debulking surgery were identified and included in the study. A retrospective image collection was operated, and CT scan evaluations were conducted by 2 independent radiologists to establish both scores (Fagotti index and Sugarbaker PCI).

Inflammatory myofibroblastic tumors (IMTs) are rare mesenchymal neoplasms with intermediate biological potential and are characterized by spindle-shaped myofibroblastic cells and significant inflammatory infiltrates. This case report describes a 24-year-old male with diabetes who was admitted to the hospital for over three days of vomiting and abdominal pain and was initially diagnosed with diabetic ketoacidosis. Upon admission, an abdominal CT scan revealed a large cystic-solid mass in the abdominal cavity and multiple nodules in the mesentery, omentum, and peritoneum, suggesting a preliminary diagnosis of an intra-abdominal mesenchymal tumor with peritoneal metastasis.
