Here, we conducted a retrospective cohort study of 66 patients with initially G1/2 panNET (median initial Ki67, 4.6%). Patients were followed up for a median 6.8 years and had a median of two metachronous tumor biopsies over their disease course. 34.8% of patients underwent any form of grade progression, including G1 to G2/3 and G2 to G3, while 24.2% demonstrated G1/2 to G3 grade progression. Over a median 2.3 years, G1/2 to G3 grade progressors experienced a median Ki67 change of +27.0% (range, +6.4 to +48.7%). Subsequent biopsies showing progression to G3 had a median Ki67 value of 31.0% (range, 21.0-60.0%) and were more often performed following suspicious clinical behavior (75.0%) rather than routinely at the time of scheduled procedure/surgery (25.0%). Similar to prior studies, G1/2 to G3 grade progressors had worse overall survival from the time of metastatic disease (median, 4.8 years vs not reached for stably G1/2 disease; P = 0.002). Heavier pretreatment and heterogeneity or lack of uptake on somatostatin receptor imaging was independently associated with progression to G3. In the largest study of metachronous panNET biopsies to date, our findings show that baseline biopsies suggesting G1/2 disease may not accurately reflect future disease status, highlighting the possible limitations of using archived tissue to stratify patients into trials and/or choose future therapy.

The temporal evolution of PanNET biology is poorly known. We aimed to study the prognostic impact of the temporal evolution of Ki-67 and other molecular markers (MEN1, ATRX/DAXX and PDX1/ARX) in PanNETs. We retrospectively studied 109 patients with sporadic PanNETs and serial tumour samples (n = 286), in which we measured the Ki-67 index and the expression of the other markers. Variables associated with shorter overall survival (OS) and Ki-67 increase over time were explored using multivariable analyses. The median time between the initial and last samples was 49.4 months, with a median variation in Ki-67 of +4% (interquartile range (IQR): -1 to +15%; P < 0.001) and +0.5%/year (IQR: -0.2 to +3.3%). Tumour grade increased in 36% of cases. At multivariable analysis, an increase in Ki-67 ≥ 2%/year was associated with shorter OS (HR 1.96, 95% CI [1.02-3.73], P = 0.041). This variation was more common in patients who received alkylating agents (OR 4.47, 95% CI [1.48-15.38], P = 0.011) and was less common in those who achieved tumour control with somatostatin analogues (OR 0.27, 95% CI [0.08-0.82], P = 0.027).

Additional immunofluorescence staining and coculture experiments with the ATC cell line identified GNLY, a member of the saposin-like protein family, as a potential biomarker for pre-exhausted CD8+ T cells in ATC. This study provides valuable insights into the immune landscape of ATC, emphasizing the prevalence of pre-exhausted CD8+ T cells and identifying GNLY as a potential biomarker.

Needle tract seeding (NTS) is a rare complication of biopsies in general, and its true incidence remains unknown. This study aimed to assess the risk of NTS in patients with thyroid cancer who underwent bone biopsy. For our cohort, we extracted data from the electronic medical record at the Mayo Clinic in Rochester (Minnesota, USA). Inclusion criteria included patients with a history of thyroid cancer who underwent biopsy for bone metastasis between 1/1/2014 and 10/1/2023. We identified a cohort of 20 patients that fit our inclusion criteria. Of these 20 patients, 2 patients developed NTS after CT-guided bone biopsy. Cases of seeding had a larger tumor size, a more aggressive histopathological presentation, a significantly shorter duration between cancer diagnosis and bone metastasis, and underwent more tumor manipulation procedures, such as biopsy and radiofrequency ablation, in contrast to those without seeding. In conclusion, our study identified NTS to have an incidence of 10% after biopsies of bone metastasis related to thyroid carcinoma. These are likely the result of an interplay of risk factors, including tumor biology, penetrated tissues and procedural technical details. Further studies with larger sample sizes are needed to confirm our findings and identify strategies to mitigate NTS.</p>","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142924302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanisms of resistance include genomic aberrations at the AR locus that reactivate AR signaling or lineage plasticity that drives emergence of AR-independent phenotypes. Given the diverse mechanisms of ARSI resistance in CRPC, there is a need for more effective monitoring strategies that detect signs of resistance to inform prognosis and guide use of alternative therapies. Liquid biopsy is a blood test that has emerged as a powerful, minimally invasive tool for investigating advanced cancer. In CRPC, liquid biopsy has been shown to reflect genomic and transcriptomic features in tumor tissue and has been utilized to detect an array of resistance signatures. Liquid biopsy is uninhibited by spatial restrictions and allows for longitudinal monitoring of disease progression. However, current clinical liquid biopsy tests provide limited actionable information. This review highlights recent advancements to the understanding of mechanisms driving treatment resistance in CRPC through research-grade liquid biopsy assays.

Skeletal metastasis is a multistage process, with primary stages of circulating tumour cells, progressing to a dormant state in vasculature and bone marrow niches, followed by tumourigenic reactivation, proliferation and finally bone destruction. The frequency of bone metastasis is reconciled in Paget's 'seed and soil' hypothesis, where a conducive microenvironment (bone niche) is essential for cancer cell colonisation. Cancer cells can mimic bone cells (osteomimicry) and interact with the bone marrow's vascular architecture, utilising pathways akin to haematopoietic stem cell expansion. Current research suggests that each phase of bone metastasis is associated with specific gene expression and protein abundance patterns. For example, E-selectin, CXCR-4 and CXCL-12 are crucial for cancer cell homing, dormancy and colonisation of bone tissue. In contrast, different primary cancers appear to have unique staging profiles. In prostate cancer, dormancy is modulated by the CXCR-4/CXCL-12, ANXA2/CXCL12 and GAS6 pathways, while in breast cancer, dormancy involves ERK1/2, p38, MSK1, LIF, BMP-7, TGF-β1/2 and bone resorption factors. Conversely, osteoblastic metastasis in both breast and prostate cancers is characterised by ET-1, Dkk1 suppression and the release of IL-6, MCP-1, VEGF, FGF and IGF, while osteolytic metastasis primarily depends on PTHrP, RANKL, OPG, TGF-β, IGF, TNF-α, IL-1 and IL-7.
