Although curable in most cases, approximately 4% of patients develop locally advanced or metastatic disease (advBCC) requiring systemic therapy. Hedgehog pathway inhibitors (HHIs; vismodegib/sonidegib) constitute standard first-line treatment, yet individual responses vary and no histopathological biomarker predicting therapeutic outcome exists. We conducted a retrospective, multicenter analysis of 70 BCCs encompassing clinically common and advanced stages. Routine hematoxylin and eosin and Alcian blue (AB; pH 2.5) staining was evaluated using a 17-parameter, numerically encoded histopathology matrix spanning tumor morphology, stromal composition, and immune contexture. Data were mapped by unsupervised hierarchical clustering. Distinct AB staining patterns were observed: superficial and nodular BCCs typically exhibited an AB-positive peritumoral border, whereas infiltrative and sclerosing subtypes displayed a diffuse AB-positive desmoplastic stroma. The latter also correlated with advanced EADO clinical stages (correlation coefficients 0.46–0.48; <i>p</i> < 0.001). In a subset of 30 advBCCs obtained before or during HHI therapy, AB-positive stroma was the only parameter independently associated with shorter progression-free survival (multivariable hazard ratio = 23.8; 95% CI 4.02–141.3; <i>p</i> < 0.001). Established clinical or histological features failed to associate with outcome. Our findings identify diffuse AB-positive stroma as a readily detectable feature of histologically aggressive BCC and as a candidate biomarker associated with progression under HHI treatment. Because AB staining is routine, inexpensive, and easily standardized, this phenotype represents an immediately implementable readout for prospective validation and a potential link between extracellular-matrix remodeling and therapy resistance in BCC.</p>","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"12 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12810521/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145991384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected tissue samples from 167 prostate cancer patients and performed genomic sequencing to assess homologous recombination deficiency scores.

We examined the predictive value of homologous recombination deficiency scores in forecasting the therapeutic efficacy of standard-of-care treatment of prostate cancer under different disease stages. Among patients who underwent radical prostatectomy, those with higher homologous recombination deficiency scores experienced notably shorter biochemical progression-free survival and overall survival than those with lower scores (median biochemical progression-free survival: 50.6 versus 148.4 months, <i>p</i> = 0.037; median overall survival: 149.0 months versus not reached, <i>p</i> = 0.0018). In patients receiving androgen receptor pathway inhibitor treatment, men with higher homologous recombination deficiency scores exhibited reduced prostate-specific antigen progression-free survival, radiographic progression-free survival, and overall survival compared to the lower score group at the metastatic castration-resistant stage (median prostate-specific antigen progression-free survival: 8.17 versus 24.17 months, <i>p</i> = 0.032; median radiographic progression-free survival: 11.8 versus 24.8 months, <i>p</i> = 0.015; median overall survival: 36.5 months versus not reached, <i>p</i> = 0.056) and a deteriorating trend in the metastatic hormone-sensitive stage.

Large international cohort studies have validated its ability to predict benefit from adjuvant chemotherapy in stage III colon cancer. More recently, Immunoscore-IC – a refined version that incorporates PD-L1<sup>+</sup> cell density and spatial interactions – has emerged as the first biomarker capable of identifying the subset of patients with proficient-MMR (pMMR/MSS) metastatic CRC who derive significant benefit from immune checkpoint inhibitors.

Addressing some of these challenges could enhance its utility and facilitate broader integration into routine pathology practice.

While molecular testing is the diagnostic gold standard in endemic areas, HTLV-1/2 serology is often used as a surrogate in nonendemic settings, yet its accuracy and limitations remain unclear. We retrospectively analyzed 881 PTCL cases over 25 years at two tertiary referral hospitals in Taiwan, where HTLV-1 is nonendemic. Serology was available in 48.2% of cases. Molecular confirmation was performed using <i>HBZ in situ</i> hybridization and <i>tax</i> quantitative polymerase chain reaction. Among the 44 seropositive PTCL patients with tissue available, 37 were diagnosed and molecularly confirmed as ATLL. Of the seven initially diagnosed as non-ATLL PTCL, three were reclassified as ATLL, while four showed no molecular evidence, including three likely false seropositives with borderline signal-to-cutoff (S/CO) values in serology assay and T follicular helper cell phenotype. In seropositive PTCL, clinicopathologic interpretation without molecular testing yielded 100% positive predictive value, 93% sensitivity, and 93% accuracy, compared with 91% positive predictive value by serology alone. In addition, retrospective molecular screening in 59 PTCL without prior serologic data revealed one case of ATLL that had initially been overlooked. In conclusion, our findings support routine HTLV-1/2 serologic testing in all newly diagnosed PTCLs. However, interpretation should be guided by clinicopathological correlation and serology index values.
