Oral squamous cell carcinoma (OSCC) accounts for over 90% of oral malignancies, with more than 370 000 new cases and approximately 188 000 deaths annually worldwide. In China, there are roughly 65 000 new cases and 35 000 deaths each year, showing a significant upward trend compared with 2015 statistics. Despite continuous advancements in treatment modalities, the 5-year survival rate remains stagnant at 50%-60%, where tumor heterogeneity and therapy resistance persist as fundamental barriers to precision oncology. To address these critical challenges, this study established a standardized bioban-king protocol for OSCC patient-derived organoids (PDOs) (Patent: Method for constructing an oral squamous cell carcinoma organoid bank, ZL202311378598.3). Through groundbreaking optimization of culture media, enzymatic digestion kinetics, and stepwise cryopreservation, we achieved a biobanking success rate exceeding 95% and pioneered synchronous cultivation of matched primary tumors, lymph node metastases, and adjacent normal mucosa from individual patients, preserving spatial heterogeneity and stromal interactions. Leveraging this platform, we developed high-throughput drug screening: Quantified heterogeneity-driven differential chemoresponse using adenosine triphosphate (ATP)-based viability assays; We discovered resistance mechanisms: Identified sialylated cancer IgG (SIA-cIgG)-mediated cis-platin resistance (primary/secondary) through PTPN13 suppression, with anti-SIA-cIgG combination therapy demonstrating synergistic efficacy. Besides, we elucidated metastatic drivers: CRISPR-Cas9-edited organoids revealed WDR54 promoted metastasis via H3K4me3/H4K16ac epigenetic reprogramming, activating epithelial-mesenchymal plasticity (EMP) and inducing partial epithelial-mesenchymal transition (pEMT). This "holographic patient-mirroring" platform provided unprecedented resolution for OSCC precision therapy and had been formally incorporated into the Chinese Stomatological Association Technical Guidelines (Technical guideline for establishing patient-derived oral squamous cell carcinoma organoid banks, CHSA 2024-08). Future integration of immune-competent organoids, 3D-bioprinted vasculature, and multi-omics-AI systems will accelerate personalized oncology. These innovations will accelerate clinical translation of personalized therapeutic regimens, ultimately bridging the gap between bench research and bedside application.

Professor Salvador Salceda described the history of Philippine eye banking as “a fascinating if not frustrating one”. This is evident in his Geminiano de Ocampo Medical Research Foundation Centennial Lecture where he traced the ebb and flow of Philippine eye banking from 1948 until the birth of the Eye Bank Foundation of the Philippines in 1994 and the start of operations of its Medical Eye Bank in 1995.1 The story of Philippine eye banking remains a fascinating one, but it has fortunately also been blessed with many moments of success and satisfaction even while still laden with frustration. In an editorial about the Eye Bank in 2005, I wrote that “while the achievements after ten years of operations can be considered a success story, we have really only started to plant the seeds”.2 And now, thirty years hence, after the COVID-19 pandemic that saw the number of cornea retrieval procedures plunge throughout the world, I believe we are starting to reap the harvest from the seeds planted throughout the last three decades.

PURPOSE: To evaluate changes in the expression of androgen receptor (AR) and its variants (ARVs) in human prostate cancer (PCa) tissues according to disease status, and its prognostic significance following radical prostatectomy (RP). MATERIALS AND METHODS: A total of 282 PCa cases were evaluated, which included 252 localized PCa, 8 metastatic castration resistant prostate cancer (CRPC), and 22 benign prostatic hyperplasia (BPH) cases. Samples were collected from patients who underwent RP or transurethral resection and were stored in ethically approved tissue banks. Quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry were performed for AR and ARVs. Each tissue was confirmed as cancerous (greater than 80%) using hematoxylin and eosin staining. AR and ARVs expression was compared according to disease status. The biochemical recurrence free survival (BCRFS) rates in men with localized PCa was analyzed according to AR and ARV7 expression using the Kaplan-Meier curve. RESULTS: Only 58 of the 252 localized PCa were included in the analysis because of insufficient cancer tissue. AR and ARV7 mRNA expression was higher in the CRPC tissue than in the localized PCa tissue (p=0.025, p=0.002, respectively). In localized PCa tissue, high AR mRNA and protein level was associated with a low BCRFS rate (log-ranked, p=0.019, p < 0.001, respectively). CONCLUSIONS: Overall AR and ARV7 mRNA expression levels were increased in CRPC tissues compared to localized PCa and BPH tissues. High AR protein and mRNA expression in the tumor tissue may be considered a predictive factor of BCRFS following RP.

Advances in cellular and molecular biology underpin most current therapeutic advances in medicine. Such advances for neurological and neurodegenerative diseases are hindered by the lack of similar specimens. It is becoming increasingly evident that greater access to human brain tissue is necessary to understand both the cellular biology of these diseases and their variation. Research in these areas is vital to the development of viable therapeutic options for these currently untreatable diseases. The development and coordination of human brain specimen collection through brain banks is evolving. This perspective article from the Sydney Brain Bank reviews data concerning the best ways to collect and store material for different research purposes.

In terminally ill patients, organ transplantation could be recommended as the treatment of choice. In Korea, living donor liver or kidney transplantation is much more frequent than deceased donor transplantation due to organ shortages from deceased donors. ABO or HLA incompatibility in transplantation can be a major barrier in living donor transplantation. Currently, the rate of ABO incompatible organ transplantation accompanied by desensitization is 20~25% of living donor transplantation, and the blood bank laboratory plays an active role by plasmapheresis. The desensitization of HLA incompatible transplantation in highly sensitized patients is more difficult than that of ABO incompatible transplantation. The HLA antibody is not easy to remove and it is difficult to prevent sensitization. In addition, setting the target treatment goals and predicting the treatment outcomes based on the HLA antibody results are problematic. Therefore, a range of desensitization protocols have been attempted and various therapeutic goals have been introduced. This article reviews the various desensitization methods for antibody removal focusing on HLA incompatible kidney transplantation, and discusses the prognosis of desensitization methods for antibody removal based on the literature.

The rate of acetabular cup revision arthroplasty is gradually rising along with an increased risk of osteolysis and prosthesis loosening over time and an increase in life expectancy. The goals of revision total hip arthroplasty are: i) implant stability through reconstruction of large bone defects, ii) restoration of range of motion and biomechanics of the hip joint, and iii) normalization of uneven limb lengths. In acetabular cup revision arthroplasty, stable fixation of acetabular components is difficult in the presence of severe bone loss (e.g., evidence suggests that it is challenging to achieve satisfactory results in cases of Paprosky type 3 or higher bone defects using conventional techniques). The author of this study performed acetabular revision to manage patients with large areas of defective bones by filling in with morselized impaction allografts. These allografts were irradiated frozen-stored femoral heads acquired from a tissue bank, and were applied to areas of an acetabular bone defect followed by insertion of a cementless cup. When this procedure was insufficient to obtain primary fixation, a tri-cortical or structural allograft using a femoral head was carried out. Structural stability and bone incorporation were confirmed via long-term follow-up. This study aims to review conventional surgical techniques and verify the utility of surgical procedures by analyzing the author's surgical methods and discussing case reports.
