Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Objective:To develop and design a during-treatment records auto-review program to comply the quality assurance(QA)requirement of radiotherapy chart auditing,and thereby improve the review efficiency and accuracy.Methods:Based on the items the guideline required,the Aria Oncology Information System database backup files was analyzed by Java,Vue,and etc.languages and the corresponding review logic was formulated.A total of 530 treatment records generated at Shanghai Concord Cancer Center from January to March 2024(10 weeks)were auto-reviewed and compared with the manual results for evaluating the accuracy and efficiency of the program.Results:The auto-review program was running smoothly.Overall with the above data,the sensitivity,specificity,accuracy and the error-miss rate were 73.4%,14.3%,87.7%and 12.3%respectively.For sub-set items,the source-skin distance(SSD)error detecting rate was 100%,the wrong session reporting was 100%correlated with the plans switching and the wrong fraction reporting was 100%related to plan revision.For the other items,auto and manual reviews gave out the same accuracy.Conclusion:The none-error results from the program are all true,so the manual rechecking could limit to those auto-review error records,which can reduce the workload by 73.4%,therefore improve the effectiveness and accuracy of the radiotherapy data review.

Purpose To investigate the clinicopathologic characteristics, differential diagnosis, treatment and prognosis of differentia-ted-type vulvar intraepithelial neoplasia ( dVIN) . Methods Clinicopathologic findings and immunophenotypes of 6 cases diagnosed as“dVIN” were retrospectively analyzed, and the relevant literatures were also reviewed. Results 6 patients were all female ranged 53~80 years old with mean age of 62 years old. Clinical aspects included leukoplakia vulvar, pruitis, irritation, pain, ulcer and so on. The histopathological features were hyperplasia of basal and parabasal layer with elongation and anastomosing reteridges. Cells were marked atypia with obvious nucleoli, atypical mitosis, and dyskeratosis. In the middle and surface layer, cells were well differentiated with pronounced intercellular bridges, and eosinophilic cytoplasm, hyperkeratosis and parakeratosis. Oedema and band of infiltration of chronic inflammatory cells of subepidermal could been seen. Immuohistochemistry showed the expression rates of p53 and p16 in totally 6 cases were 83. 3% (5/6), 0 (0/6), respectively. The Ki-67 index was more than 90% in basal and parabasal cells. Four patients were followed up ( mean follow-up 17 months, range 6~36 months) , one patient died at 9 months later after surgery, another patient recurred at 6 months later after surgery, both of the 2 cases were all with invasive lesions after resection, and the rest two cases had no recur in 18 months and 36 months after surgery, respectively. Conclusion dVIN is a high grade squamous intraepithelial lesions of vulvar with low incidence rate, but had more risk of progression. p53, p16 and Ki-67 stain were useful in the diagnosis of dVIN.
