BMC Surg 2023; 23:370. [PMID: 38066512 PMCID: PMC10704770 DOI: 10.1186/s12893-023-02256-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 11/02/2023] [Indexed: 12/18/2023] Open
Abstract
OBJECTIVE To investigate the prognostic prediction of a new indicator, combined by tumor grade and Ki-67, in patients with resected pancreatic ductal adenocarcinoma (PDAC). METHODS Data were retrospectively collected from consecutive patients who underwent primary resection of pancreas from December 2012 to December 2017. Tumor grade and Ki-67 were reviewed from routine pathological reports. G-Ki67 was classified as three categories as I (G1/2 and Ki-67 < 40%), II (G1/2 and Ki-67 ≥ 40%), and III(G3/4 and all Ki-67). RESULTS Cox regression analyses revealed that tumor stage (II vs. I: hazard ratio (HR), 3.781; 95% confidence index (CI), 2.844-5.025; P < 0.001; III vs. I: HR, 7.476; 95% CI, 5.481-10.20; P < 0.001) and G-Ki67 (II vs. I: HR, 1.299; 95% CI, 1.038-1.624; P = 0.022; III vs. I: HR, 1.942; 95% CI, 1.477-2.554; P < 0.001) were independent prognostic factors in the developing cohort. The result was rectified in the validation cohort. In subgroups analysis, G-Ki67 (II vs. I: HR, 1.866 ; 95% CI, 1.045-3.334; P = 0.035; III vs. I: HR, 2.333 ; 95% CI, 1.156-4.705; P = 0.018) also had a high differentiation for survival prediction. CONCLUSION Our findings indicate that three-categories of G-Ki67 in resectable PDAC according to the routine pathological descriptions provided additional prognostic information complementary to the TNM staging system.

Colorectal Cancer Liver Metastases: Genomics and Biomarkers with Focus on Local Therapies. Cancers (Basel) 2023; 15:cancers15061679. [PMID: 36980565 PMCID: PMC10046329 DOI: 10.3390/cancers15061679] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 02/23/2023] [Accepted: 03/03/2023] [Indexed: 03/11/2023] Open
Abstract
Molecular cancer biomarkers help personalize treatment, predict oncologic outcomes, and identify patients who can benefit from specific targeted therapies. Colorectal cancer (CRC) is the third-most common cancer, with the liver being the most frequent visceral metastatic site. KRAS, NRAS, BRAF V600E Mutations, DNA Mismatch Repair Deficiency/Microsatellite Instability Status, HER2 Amplification, and NTRK Fusions are NCCN approved and actionable molecular biomarkers for colorectal cancer. Additional biomarkers are also described and can be helpful in different image-guided hepatic directed therapies specifically for CRLM. For example, tumors maintaining the Ki-67 proliferation marker after thermal ablation was shown to be particularly resilient to ablation. Ablation margin was also shown to be an important factor in predicting local recurrence, with a ≥10 mm minimal ablation margin being required to attain local tumor control, especially for patients with mutant KRAS CRLM.

Rapid intraoperative Ki-67 immunohistochemistry for lung cancer using non-contact alternating current electric field mixing. Lung Cancer 2022; 173:75-82. [PMID: 36156324 DOI: 10.1016/j.lungcan.2022.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 07/07/2022] [Accepted: 09/08/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVES Locoregional recurrence of non-small cell lung cancer (NSCLC) occurs even among patients with stage I disease, as a result of tumor proliferative activity. The aim of this study was to evaluate the clinical reliability of a new rapid immunohistochemistry (IHC) technique for assessing malignant potential through detection of tumoral Ki-67 expression. MATERIALS AND METHODS The rapid IHC method uses non-contact alternating current (AC) mixing to achieve more rapid/stable staining within 20 min during surgery. First, to investigate the association between clinical outcomes and tumoral Ki-67 labeling with rapid IHC, 21 pairs of surgical patients treated between 2012 and 2020 for pStage IA1-3 NSCLC with/without recurrence were retrospectively reviewed. Second, 40 frozen section (FS) samples in patients with NSCLC for whom radical surgery was planned between April 2021 and February 2022 were deemed eligible for comparison of the clinical performance of conventional IHC and intraoperative rapid Ki-67 IHC with FS. RESULTS Detection of tumoral Ki-67 expression using rapid IHC with formalin-fixed, paraffin-embedded (FFPE) blocks was significantly associated with clinical outcomes in R0 pStage IA NSCLC surgical patients, including overall and recurrence-free survival (P = 0.0043 and P < 0.0001, respectively). Levels of Ki-67 expression among resectable NSCLC patients detected using rapid IHC with FS significantly correlated with those detected using conventional FFPE-IHC (p < 0.001). An intraoperative cut-off of > 7.5 % tumor cell Ki-67 positivity accurately predicted pathological stage more advanced than IA3 [P = 0.0185, Odds ratio = 20.477, 95 % confidence interval (CI): 1.660-252.55]. CONCLUSION Rapid Ki-67 IHC with AC mixing could potentially serve as a clinical tool for intraoperative determination of tumor malignancy status. The present study suggests that segmentectomy for early small NSCLCs is oncologically safe and a reasonable alternative to lobectomy, but only when there is adequate intraoperative selection for primary tumors with low-grade malignancy, which could be verified using intraoperative rapid Ki-67 IHC with FS.

Abstract
BACKGROUND Lung adenocarcinoma (LUAD) is one of the most prevalent human cancers worldwide. The homeobox-B (HOXB) gene cluster has been reported to contribute to cancer development. Nevertheless, the expression status, clinical significance and biological role of HOXB genes in LUAD remain largely unclear. METHODS AND RESULTS This study comprehensively investigated the transcriptional levels and prognostic values of the HOXB genes in LUAD based on The Cancer Genome Atlas (TCGA) database. Flow cytometry, CCK-8, and Transwell assays were used for detecting apoptosis, proliferation, and migration, respectively. We discovered that eight members of the HOXB cluster genes (HOXB2, HOXB3, HOXB4, HOXB6, HOXB7, HOXB8, HOXB9, and HOXB13) were dysregulated in LUAD tumor tissues. Increased expression of HOXB3, HOXB6, HOXB7, HOXB8, or HOXB9 was independently associated with unsatisfactory overall survival (OS) in LUAD patients. In addition, a high level of HOXB3 also predicted poor patient relapse-free survival (RFS), suggesting that HOXB3 may play a vital role in the progression of LUAD compared to other members of the HOXB cluster. Additionally, further analysis by TIMER and TISIDB algorithms revealed that HOXB3 was positively correlated with a panel of immune checkpoint molecules (ICMs), tumor-infiltrating lymphocytes (TILs), and tumor immune regulators (TIRs). Gene enrichment analysis based on KEGG showed that HOXB3 was closely associated with multiple tumor-related biological processes and signaling pathways. Functionally, the in vitro experiments revealed that depletion of HOXB3 significantly alleviated the resistance of LUAD cells to apoptosis, and suppressed cell proliferation and migration. CONCLUSION Our study suggests that HOXB3 may play an oncogenic role in LUAD and correlate with tumor immunity.
