Abstract
Gastric cancer (GC), notorious for its poor prognosis, often advances to peritoneal dissemination, a crucial determinant of detrimental outcomes. This study intricately explores the role of the TGFβ-Smad-LIF axis within the tumor microenvironment in propagating peritoneal metastasis, with a specific emphasis on its molecular mechanism in instigating Neutrophil Extracellular Traps (NETs) formation and encouraging GC cellular functions. Through a blend of bioinformatics analyses, utilizing TCGA and GEO databases, and meticulous in vivo and in vitro experiments, LIF was identified as pivotally associated with GC metastasis, notably, enhancing the NETs formation through neutrophil stimulation. Mechanistically, TGF-β was substantiated to elevate LIF expression via the activation of the Smad2/3 complex, culminating in NETs formation and consequently, propelling peritoneal metastasis of GC. This revelation uncovers a novel potential therapeutic target, promising a new avenue in managing GC and mitigating its metastatic propensities.

Marshall M, Elishaev E, Khader S. The diagnostic accuracy and prognostic implication of pelvic and peritoneal fluid cytology specimens in ovarian clear cell carcinoma. J Am Soc Cytopathol 2024; 13:53-58. [PMID: 37865568 DOI: 10.1016/j.jasc.2023.09.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/11/2023] [Accepted: 09/11/2023] [Indexed: 10/23/2023]
Abstract
INTRODUCTION Ovarian clear cell carcinoma (OCCC) is a rare subtype of ovarian epithelial carcinoma. Patients with low-stage disease have an excellent prognosis, while the prognosis for those with high-stage disease is poor. Neoplastic cells in abdominopelvic washings upstages the patient to at least FIGO 1C3. Positive cytology confers a worse prognosis when compared to similar stage patients with negative cytology. This study aims to investigate the diagnostic performance of abdominopelvic fluid cytology specimens in cases with pure OCCC and reaffirm the importance of accurate cytologic detection and its impact on patient prognosis. MATERIALS AND METHODS The laboratory information system was queried to identify all patients treated for ovarian clear cell carcinoma at our institution over a period of 20 years with a companion abdominopelvic fluid cytology specimen at the time of surgical resection. Cases were sorted by the FIGO stage of the corresponding oophorectomy specimen. Cytology results, patient demographics, fluid volume, immunohistochemical results, and follow-up data were recorded. RESULTS A total of 143 cases were identified. The overall detection rate was 38%, with 54 of 143 cases positive for malignancy. Cytologic detection rates increased as FIGO stages increased. Fifty percent of stage 1C cases were upstaged on cytology alone. Ascites fluids performed better among stage 1 cases compared to pelvic wash specimens (77% detection rate versus 23%). Stage 1 patients with positive cytology trended towards a worse prognosis compared to those with negative cytology. CONCLUSIONS Positive cytology in low stage cases of OCCC has significant prognostic and therapeutic implications. Our large cohort further underscores the importance of accurate cytologic detection and subsequent staging in this setting.

Evaluation of the Cell Block Method Using Overnight-Stored Bile for Malignant Biliary Stricture Diagnosis. Cancers (Basel) 2022; 14:cancers14112701.

Abstract
The specimen collection and subsequent pathological diagnosis of malignant biliary stricture (MBS) are difficult. This study aimed to determine whether the cell block (CB) method using overnight-stored bile is useful in the diagnosis of MBS. This trial was a single-arm prospective study involving a total of 59 patients with suspected MBS. The primary endpoint was cancer detectability and accuracy using the CB method, and a comparison with the detectability and accuracy achieved with bile cytology was made. The immunohistochemical sensitivity for maspin and p53 was also investigated in the CB and surgical specimens. We were able to collect bile from all 59 patients, and 45 of these patients were clinically diagnosed with MBS. The cancer detectability using the CB method (62.2%) was significantly higher than that using cytology (37.8%) (p = 0.0344). When CB was combined with biopsy, the rates of cancer detectability (75.6%) and accuracy (81.4%) increased. In eight patients who received surgical therapy, maspin- and p53-immunohistochemistry was applied to the surgical and CB specimens, and cancer cells in both specimens showed positive cytoplasmic and nuclear staining for maspin and nuclear staining for p53. The CB method is, thus, useful for detecting malignancy (UMIN000034707).

Clinical significance of CD8-positive lymphocytes on tumor cell clusters of ascites cell block in ovarian high-grade serous carcinoma. Cancer Med 2022; 11:2085-2095. [PMID: 35137571 PMCID: PMC9119359 DOI: 10.1002/cam4.4592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/20/2021] [Accepted: 12/23/2021] [Indexed: 11/11/2022] Open
Abstract
Background The clinical significance of CD8‐positive (CD8+) lymphocytes on tumor cell clusters of ascites cell blocks in patients with ovarian high‐grade serous carcinoma (HGSC) was investigated. Methods Among HGSC patients who underwent surgery from January 2014 to December 2019, 38 patients with ascites cell block were selected. Using these cell blocks and primary ovarian tumor tissue, the presence of CD8+ lymphocytes and the expression of PD‐L1 were examined immunohistochemically. Tumor cell clusters were defined as cell clumps consisting of more than 10 malignant cells in cell block. Cases with at least one CD8+ lymphocyte in tumor cell cluster were defined as positive CD8+ lymphocytes (Group A); others were defined as negative CD8+ lymphocytes (Group B). The tumor tissue CD8+ lymphocytes were counted mechanically. Clinicopathological features were retrospectively compared between the two groups. Results In total, 38 cases were identified: 25 (65.8%) in Group A and 13 (34.2%) in Group B. More cases in Group A were positive for CD4 (p < 0.01), PD‐L1 (p = 0.02), FoxP3 (p = 0.02) and had a higher number of CD8+ lymphocytes in the tissue (p = 0.03). Patients in Group A had better progression‐free survival (p < 0.01) and overall survival (p = 0.04). In multivariate analysis, Group A was an independent prognostic factor for both progression‐free survival (hazard ratio, 0.24; p < 0.01) and overall survival (hazard ratio, 0.21; p = 0.03). Conclusion The presence of CD8+ lymphocytes in tumor cell clusters of ascites was associated with the status of immune reaction in the tissue and prognosis in patients with HGSC and might be useful information of the immune‐associated therapy.
