To evaluate the effect of palliative care on drug use, medical service utilization and medical expenditure of patients with advanced cancer.

A cohort of patients including pal-liative care and standard care was constructed using the medical records of the patients in Peking University Cancer Hospital from 2018 to 2020, and coarsened exact matching was used to match the two groups of patients. The average monthly opioid consumption, hospitalization rate, intensive care unit (ICU) rate and operation rate, and the average monthly total cost were selected to evaluate drug use, medical service utilization and medical expenditure. Chi-square test and Wilcoxon signed rank test were used to compare the differences between the two groups before and after exposure and the change in the palliative care group. The net impact of palliative care on the patients was calculated using the difference-in-differences analysis.

In this study, 180 patients in the palliative care group and 3 101 patients in the stan-dard care group were finally included in the matching, and the matching effect of the two groups was good (L₁ < 0.1). Before and after exposure, the average monthly opioid consumption in the palliative care group was significantly higher than that in the standard care group (Before exposure: 0.3 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; After exposure: 0.7 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; DDD refers to defined daily dose), palliative care significantly increased the average monthly opioid consumption in the patients (0.3 DDD/person-month, P < 0.01). The hospitalization rate (48.9% vs. 74.3%, P < 0.01) and operation rate (3.9% vs. 8.8%, P < 0.01) of the patients in palliative care group were significantly lower than those in standard care group, and the ICU rate became similar between the two groups (1.1% vs. 1.6%, P=0.634). Palliative care significantly reduced the patients ' hospitalization rate (-25.6%, P < 0.01), ICU rate (-4.9%, P < 0.01) and operation rate (-14.5%, P < 0.01). Before and after exposure, the average monthly total costs of pal-liative care group were slightly higher than those of standard care group (Before exposure: 20 092.3 yuan vs. 19 132.8 yuan, P=0.725; After exposure: 9 719.8 yuan vs. 8 818.8 yuan, P=0.165). Palliative care increased the average monthly total cost by 2 208.8 yuan, but it was not statistically significant (P=0.316).

Palliative care can increase the opioid consumption in advanced cancer patients, reduce the rates of hospitalization, ICU and surgery, but has no significant effect on medical expenditure.

To investigate the safety and prognostic factors influencing the treatment of upper urinary tract urothelial carcinoma (UTUC) combined with bladder cancer (BCa) by laparoscopic simultaneous radical cystectomy and nephroureterectomy (RCNU).

The clinical data of patients admitted to Peking University Third Hospital for laparoscopic RCNU surgery from January 2009 to September 2023 were analyzed retrospectively. Based on the same gender, age (±5 years), history of uroepithelial tumors, underlying diseases, T-stage, N-stage, M-stage, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, and body mass index (BMI) (±5), 34 patients with RCNU were matched 1 ∶1 with patients with bladder cancer who underwent laparoscopic radical cystectomy (RC) alone. Kaplan-Meier survival analysis was used to calculate patient survival, and Cox proportional regression risk model was used to analyze clinical factors affecting prognosis.

Of the 68 patients enrolled, the follow-up rate was 100% with a median follow-up time of 27.0 (11.7, 60.2) months. Comparison of intraoperative conditions (including operation time, estimated intraoperative bleeding, intra-operative blood transfusion, etc.) between the two groups of patients showed no significant difference (P>0.05). Comparison of preoperative creatinine and postoperative creatinine between the two groups of patients showed significant differences (P < 0.05). The perioperative Clavien grade Ⅲ-Ⅳ complication rates were 2.9% (1/34) in the RC group and 5.9% (2/34) in the RCNU group. There was no significant difference in terms of perioperative complications between the two groups. Overall survival was significantly lower in the patients receiving RCNU compared with the matched group receiving RC alone (P < 0.05). Cox regression analysis suggested that two factors, high N stage and high postoperative creatinine, were independent risk factors affecting the prognosis of patients in the 2 groups (P < 0.05).

The overall survival prognosis of patients undergoing RCNU surgery was worse compared with laparoscopic RC surgery alone during the same period. There was no clinically significant difference between the two groups in terms of operation time, intraoperative bleeding, and perioperative complications, and there were clinically significant differences in preoperative renal function and post-operative renal function.

To explore the differences in perioperative clinical and pathological characteristics of patients with different pathological types of prostate cancer undergoing radical prostatectomy, and to analyze the influencing factors that may affect the extraglandular invasion of ductal adenocarcinoma of the prostate.

Retrospective collection was made of the radical prostatectomy patients who were admitted to Peking University Third Hospital from December 2011 to April 2021. The patients were screened based on inclusion criteria to obtain basic clinical features and postoperative pathological results. According to the pathological results, the patients were divided into ductal adenocarcinoma group (mixed with ductal adenocarcinoma) and acinar adenocarcinoma group, and a 1 ∶1 propensity score matching was performed to compare the differences in clinical characteristics between the two groups. Univariate and multivariate analyses of the factors related to extraglandular invasion were performed in the matched ductal adenocarcinoma groups.

A total of 764 patients with prostate cancer were enrolled in this study, of which 62 patients were confirmed to have ductal adenocarcinoma components by postoperative pathology. There was a statistically significant difference in the proportion of the patients with a history of diabetes in baseline characteristics between the two groups before propensity score matching (29.5% vs. 17.7%, P=0.027). A total of 61 patients with simple acinar adenocarcinoma were successfully matched with the patients with ductal adenocarcinoma, and there was no statistically significant difference in baseline characteristics between the two groups after matching (P>0.05). The comparison of perioperative clinical and pathological features showed that International Society of Urology Pathology (ISUP) grade (P=0.003), pT stage (P=0.004), extraglandular invasion rate (P=0.018) and vascular thrombus rate (P=0.019) in ductal adenocarcinoma group were significantly higher than those in simple acinous adenocarcinoma group. Univariate analysis of the influence factors of extraglandular invasion showed that prostate-specific antigen (PSA) level, prostate volume, ISUP grade, seminal vesicle invasion and perineural invasion might be the influencing factors of extraglandular invasion (P < 0.10). Binary Logistic regression analysis showed that perineural invasion was an independent factor of extraglandular invasion (OR=11.78, 95%CI: 1.97-70.56, P=0.007).

Prostatic ductal adenocarcinoma has a worse prognosis than simple acinar adenocarcinoma. Perineural invasion is the influencing factor of extraglandular invasion of ductal adenocarcinoma.

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.

This study aims to develop a robust and user-friendly prediction model for radiation-induced hypothyroidism (RIHT) in nasopharyngeal carcinoma (NPC) patients.

NPC patients treated with IMRT between Jan. 2019 and Dec. 2021 were randomly assigned to a training cohort (n = 328) and a validation cohort (n = 141) at a ratio of 7:3. A total of 33 clinical and dose-volume variables were collected. Significant variables (p < 0.05) were identified through univariate Cox analysis and further refined using a 101-combination machine learning (ML) framework to develop a robust predictive model. The model was subsequently simplified through multivariate Cox analysis and a nomogram. Finally, the performance of the model was evaluated using the C-index, calibration plots, and decision curve analysis.

Using a 101-combination ML framework, we developed a predictive model for RIHT in NPC. The Coxboost + RSF method with 11 predictors achieved the best performance (C-index: 0.91 [training], 0.71 [validation]). A simplified five-variable model (pre-treatment TSH, TSH-to-thyroid-volume ratio, age, V45, V20) was created via multi-cox regression, with a C-index of 0.80 [training] and 0.71 [validation]. High-risk patients had significantly higher three-year RIHT incidences (72.3% vs. 18.6%, p < 0.0001) in the training cohort, and 67.9% versus 24.4% (p < 0.0001) in the validation cohort. The model showed strong calibration and confirmed clinical utility through decision curve analysis, supporting its use in personalized treatment planning.

We developed a ML framework to identify key predictive factors for RIHT, which was simplified into a five-variable model for clinical use, offering a robust tool for predicting RIHT risk in decision-making.

Acute myeloid leukemia (AML), characterized by aggressive relapse and dismal survival, remains a formidable challenge despite conventional therapies. Chimeric antigen receptor (CAR)-engineered T and natural killer (NK) cells have emerged as groundbreaking immunotherapies, offering targeted eradication of leukemic stem cells (LSCs) and resistant blasts. CAR-T cells, leveraging antigens like CD123 and CD33, demonstrate early clinical success, with complete remission rates up to 66% in refractory/relapsed (R/R) AML. CAR-NK cells complement this approach through inherent tumor surveillance, reduced toxicity, and "off-the-shelf" feasibility. However, barriers such as antigen escape, heterogeneous immunosuppressive microenvironments (including intratumoral microbiota variations), and on-target/off-tumor toxicity persist, limiting durable responses. Innovations in dual-targeting CARs, cytokine-armored constructs, and CRISPR-edited universal cells aim to overcome these hurdles. Emerging strategies integrating checkpoint inhibitors, metabolic modulators, and AI-driven antigen selection promise to enhance efficacy and safety. This review synthesizes the evolving landscape of CAR-T/NK therapies, critically analyzing preclinical breakthroughs, clinical trial outcomes, and persisting challenges. By addressing manufacturing scalability, cost barriers, and long-term safety, cellular immunotherapy holds transformative potential to redefine AML management. As the field advances, interdisciplinary collaboration and biomarker-guided personalization will be pivotal in translating laboratory innovations into life-saving therapies for AML patients.

The study sought to understand the experiences of patients with thyroid cancer (TC) from their own perspective and to identify the factors that affected their well-being.

This was a qualitative study based on semistructured interviews that collected both prospective and retrospective longitudinal data.

Patients were initially recruited from one National Health Service (NHS) Trust and from the contact list of a TC charity.

25 participants took part in the study: 22 female and 3 male. The inclusion criteria were: (1) adults over 18 years of age; (2) patients diagnosed with papillary or follicular TC within 5 years of diagnosis and (3) patients able to give informed consent. The exclusion criteria were: (1) diagnosis of anaplastic TC; (2) diagnosis of terminal TC with a short life span prediction and (3) codiagnosis of another condition in addition to TC.

Patients' psychological health, physical health, relationships, employment and finances are all likely to be affected by the diagnosis and treatment of TC. Negative factors that affect the overall experience can include a lack of compassion from healthcare professionals, as well as physical side effects after surgery and during recovery. Isolation and loneliness can be significant at many stages, most frequently during treatment with radioactive iodine. Anxiety and fear were widespread among participants.

The experiences of TC patients can be challenging, with well-being influenced by treatment effects, psychological distress and the quality of support available. These findings suggest that enhanced patient education, emotional support and follow-up care may help improve well-being, although further research is needed to explore how best to implement such approaches.

To explore the experiences and unmet needs of spouses of young breast cancer patients regarding fertility information support.

Qualitative study based on analysis of in-depth semistructured interviews.

A hospital in Changsha City, Hunan Province, China.

16 spouses of young breast cancer patients were selected based on the principle of maximum differentiation.

Three main themes were identified-(1) Fertility information dilemmas: fertility information overload, inadequate fertility information, insufficient sexual health cognition and improper sexual adjustment; (2) fertility desire and fertility concerns conflict: strong desire to have kids in the family, sustained fear of cancer recurrence during pregnancy, concerns about their own health and spouse's health and concerns about children's health; (3) objective challenges and multiple needs coexist: heavy economic burden, great family care pressure, anxieties and pressures of raising children, intimate relationship transformation, diverse information craving needs and professional fertility consultation needs.

Healthcare providers should pay attention to the experiences of spouses of breast cancer patients regarding fertility information support and implement timely, scientific and effective targeted interventions to improve their knowledge of fertility information and alleviate fertility concerns.

Patient-reported symptoms and functioning are valuable to understanding the tolerability of cancer treatments in clinical trials. Assessment of key side effects, physical and role functioning, and overall side effect bother in trials may be helpful for benefit-risk evaluation and useful to communicate in product labeling. Inclusion of these assessments has been supported in the literature and Food and Drug Administration guidance documents. In this article, the authors provide their perspective on the evolution of how this data has been considered in oncologic therapeutic evaluation and provide context for the research being presented by the National Cancer Institute Tolerability Consortium.

As new cancer therapies emerge and evolve, there is a need for a better understanding of their safety and tolerability. Safety and tolerability are distinct, albeit related, constructs; an unsafe treatment cannot be considered tolerable, whereas safe treatments may not be tolerable to some patients. Cancer treatment tolerability is a multidimensional construct, and is influenced both by the profile of adverse events and by whole-person factors. This commentary provides definitions of safety, tolerability, adverse events, and toxicity by relating these constructs to the adverse event reporting paradigm. Measures, including summary indicators, that reflect the tolerability of cancer treatments are also identified. The commentary concludes with a discussion of how evaluations of tolerability may be meaningfully incorporated into the design and interpretation of future cancer treatment trials.
