IntroductionThe purpose of this study was to use a Virtual Community Engagement Studio (V-CES) model to develop and refine short message service (SMS) content in English and Spanish related to dietary quality, physical activity, and sleep hygiene intended for individuals with cancer and their caregivers.MethodsCommunity expert stakeholders participated in an English or Spanish V-CES and provide actionable feedback on the content and delivery of 180 previously developed SMS messages.ResultsParticipants were nine stakeholders representative of the Southern Arizona cancer care community (eg, survivors, caregivers, healthcare providers, community health workers). SMS as a health promotion intervention strategy in context of cancer survivorship was viewed as accessible and appropriate. Actionable feedback from the V-CES included using positive affirmations, incorporating motivational strategies, using relatable language, and emphasizing evidence. Spanish language SMS should consider regional context during translation. Stakeholders recommended that two SMS be sent daily to dyads between 8:00 am and 7:00 pm, at relevant times for each behavior.ConclusionFuture research will test the SMS for feasibility and acceptability among survivor-caregiver dyads. The V-CES model is an innovative approach for developing and refining dyadic health behavior interventions and may be beneficial for future research to engage communities.

Tumor immune escape is a major challenge in cancer treatment, and targeted immune escape therapy has become a key strategy for cancer treatment. As an important deubiquitinating enzyme, ubiquitin-specific protease 10 (USP10) participates in the process of tumor development by adjusting the balance between ubiquitination and deubiquitination of substrate proteins. Recently, USP10 has been shown to be closely related to tumor immune escape, where it serves to reduce the immunogenicity of tumor cells by stabilizing immune checkpoints and promotes tumor immune escape. In this review, we focus on the structural and functional characteristics of USP10 and elaborate on the biological function of USP10 in the occurrence and development of tumors, as well as its role in immune escape, including the regulation of immune checkpoints and the effect on immune cells in the immune microenvironment. It is possible to improve the efficacy of traditional cancer therapies by appropriately regulating the expression of USP10. The aim of this review is to provide a reference for further understanding the mechanism of tumor immune escape and the development of new tumor treatment methods.

BackgroundThis study meticulously outlines the evolution of the burden of malignant neoplasm of bone and articular cartilage (MNBAC) among different age and sex groups in China from 1990 to 2021, analyzes the global impact of the disease, and predicts the trend of disease burden up to 2035.MethodsLeveraging public data from the Global Burden of Disease (GBD) database spanning 1990 to 2021, this study thoroughly analyzed the characteristics of the burden of MNBAC in China and globally, including its incidence, prevalence, mortality, and disability-adjusted life years (DALYs). The joinpoint analysis method was employed to calculate the average annual percentage change (AAPC) and its 95% uncertainty interval, revealing the trend of MNBAC's impact. Furthermore, Bayesian age-period-cohort (BAPC) model was used to forecast changes in disease burden leading up to 2035.ResultsBetween 1990 and 2021, the age-standardized incidence rate (ASIR) of MNBAC in China increased from 0.65 to 1.42 per 100 000 people, and the global ASIR rose from 0.97 to 1.11 per 100 000. The AAPC for China's ASIR, age-standardized prevalence rate (ASPR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) were 2.59%, 2.71%, 1.52%, and 1.26%, and the AAPC of ASIR and ASPR of the global burden of MNBAC were 0.44% and 0.51%, respectively. The effect of age and sex on the burden of MNBAC showed significant differences. Forecasting analyses suggest that from 2022 to 2035, the burden of MNBAC in China and globally will show a declining trend.ConclusionsFrom 1990 to 2021, the disease burden of MNBAC in China has been rising among the population, particularly pronounced among older men. Although forecasts indicate a gradual reduction in the future burden of MNBAC, given China's large population base and the increasing trend of population aging, MNBAC will pose a public health challenge in China.

IntroductionThe long-acting somatostatin analogues (LA-SSAs) octreotide LAR (OCT) and lanreotide (LAN) improve progression-free survival (PFS) in gastrointestinal neuroendocrine tumors (NETs), however, no head-to-head comparison exists. We compared treatment patterns and efficacy in a small bowel and pancreatic NET population-based cohort from British Columbia, Canada.MethodsWe identified 321 patients receiving either LAN or OCT for retrospective chart review. These somatostatin analogs were evaluated for impact on progression-free and overall survival.ResultsAge, sex, ECOG, and primary site did not differ by treatment, however, LAN was more commonly used in higher grade tumors (P = 0.019). PFS was longer for patients receiving LAN than OCT (Hazard Ratio (HR) 0.60, 95% CI 0.40-0.89, P = 0.011). Similarly, overall survival (OS) was longer for patients receiving LAN than OCT (HR 0.45, 95% CI 0.28-0.73, P = 0.016). Sensitivity analysis among patients diagnosed after both agents were reimbursed showed similar results for PFS (HR 0.50, 95% CI 0.28-0.90, P = 0.018). There was similar dose escalation with LAN vs OCT (OR: 0.80, CI 0.38-1.77, P = 0.70), with 29.4% of patients in the LAN group requiring LA-SSA dose escalation compared to 34.3% in the OCT group. There was numerically less short acting octreotide use in the LAN group (P = 0.087), with none of these patients requiring short acting octreotide, compared to 8.7% of the OCT group.ConclusionLAN was associated with longer time to cancer progression, as well as less use of short acting rescue octreotide in our population-based cohort. However, given the retrospective design and reimbursement-era differences, these findings should be interpreted cautiously and warrant confirmation in prospective or head-to-head studies.

IntroductionPediatric acute leukemia is the most common childhood malignancy and one of the leading causes of cancer-related mortality worldwide, particularly, in low- and middle-income countries (LMICs), where treatment abandonment remains a major barrier to survival. Geographic accessibility and socioeconomic conditions are recognized determinants, but their combined influence in Mexico remains understudied. This study evaluated the association between geographic accessibility, socioeconomic factors, and treatment abandonment among children with acute leukemia in south-central Mexico.MethodsA prospective cohort study was conducted in Oaxaca, Puebla, and Tlaxcala from 2021 to 2023, including 574 children under 18 years diagnosed with acute lymphoblastic or myeloid leukemia. Geographic accessibility was estimated using travel distance and time from patients' residences to referral hospitals, calculated with ORS Tools in QGIS. Socioeconomic variables included public health insurance affiliation, parental education and occupation, and number of siblings. Treatment abandonment was defined per SIOP criteria as failure to initiate or discontinuation of treatment for ≥4 consecutive weeks. Multivariable logistic regression, adjusted for child's sex, age, year of diagnosis, and leukemia subtype, was used to assess associations.ResultsTreatment abandonment occurred in 16.6% of patients. In multivariable analysis, lack of public health insurance (aOR = 2.83; 95% CI: 1.39-5.76; P < 0.01) and living ≥141 km from the hospital (aOR = 1.68; 95% CI: 1.02-2.74; P = 0.03) were significantly associated with abandonment. Other factors, including number of siblings, maternal education, and fathers' occupation, were not statistically significant.ConclusionLack of public health insurance and greater distance to the hospital are key determinants of treatment abandonment in children with acute leukemia in south-central Mexico. Expanding insurance coverage, reducing indirect costs, and addressing geographic barriers are critical to improve treatment adherence and survival outcomes in this population.

IntroductionTriple-negative breast cancer (TNBC) represents approximately 10-20% of all breast cancer cases and is frequently associated with BRCA1 mutations. Numerous studies from Western populations have investigated the prevalence of germline BRCA mutations in individuals with TNBC; however, the prevalence of BRCA1/2 mutations in TNBC patients varies widely between countries and from study to study. Evidence from Asian populations, particularly Vietnamese patients, remains limited. In this study, we determined the prevalence of germline BRCA1/2 mutations among unselected Vietnamese patients with TNBC and analyzed the clinicopathological features.MethodsWe conducted a single-center retrospective study of 68 women diagnosed with TNBC at the Vietnam National Cancer Hospital. Germline BRCA1/2 testing was performed by next-generation sequencing.ResultsOverall, 19 Vietnamese patients (27.9%) had BRCA1/2 mutations, with 14 (20.6%) in BRCA1 and 5 (7.4%) in BRCA2. Three patients (4.4%) had variants of uncertain significance (2 BRCA1 mutations and 1 BRCA2 mutation). Thirteen distinct pathogenic or likely pathogenic variants (8 BRCA1 and 5 BRCA2) were found. Among patients diagnosed at ≤60 years, the prevalence of BRCA1/2 mutations was 32.0%. The average age at diagnosis for BRCA1/2 mutation carriers was notably lower than that observed in non-carriers (43.1 vs 51.7 years, P = .021). BRCA1/2 mutation carriers were also more frequently premenopausal (78.6% vs 43.9%, P = .025).ConclusionsThere is a high prevalence of BRCA1/2 mutations among TNBC patients in Vietnam. Women with TNBC in Vietnam should be screened for mutations in BRCA1/2.

Purpose: The predictive sensitivity of carbohydrate antigen 19-9 (CA19-9) in assessing the prognosis of intrahepatic cholangiocarcinoma (ICC) remains inadequate. Integrating CA19-9 with tumor volume offers a potentially viable strategy for improving prognostic accuracy. This study aimed to develop a prognostic model utilizing volume-adjusted CA19-9 (VACA) for ICC patients.

Patients and methods: A retrospective analysis was conducted on data from 436 ICC patients. These patients from two centers were divided into the training (n = 291, Center 1) and validation (n = 145, Center 2) cohorts. Using the training cohort, univariate and multivariable Cox regression analyses were employed to identify clinicopathological characteristics significantly associated with overall survival (OS) and recurrence-free survival (RFS), which enabled the construction of prognostic nomograms both with and without VACA. The nomograms' discriminatory and calibration abilities were assessed using receiver operating characteristic (ROC) curves, decision curve analysis (DCA) curves, and calibration curves, applying both training and validation cohorts.

Results: VACA emerged as an independent variable that significantly correlated with prognosis. The nomogram incorporating VACA demonstrated superior accuracy in predicting OS and RFS rates compared to the model without VACA. In the validation cohort, the nomogram with VACA yielded area under the ROC curve (AUC) values of 0.695 (95% CI = 0.597∼0.793) and 0.666 (95% CI = 0.559∼0.773) (1- year), 0.662 (95% CI = 0.518∼0.806) and 0.651 (95% CI = 0.446∼0.857) (3- years), and 0.701 (95% CI = 0.486∼0.916) and 0.703 (95% CI = 0.428∼0.978) (5- years) for OS and RFS, respectively, along with improved calibration and DCA curves.

Conclusions: VACA, formed by integrating tumor volume with CA19-9, exhibits promising prognostic capabilities. The nomogram incorporating data from two centers and utilizing VACA demonstrates robust prognostic performance and holds clinical utility.

Condensed abstract: Combining CA19-9 with tumor volume presents a potentially viable strategy for improving prognostic accuracy. The nomogram incorporating VACA demonstrates robust prognostic performance and holds clinical utility.

BackgroundLocal advanced rectal cancer (LARC) patients who achieved pathological complete response (pCR) after neoadjuvant chemoradiotherapy (NCRT) generally have a favorable prognosis. This retrospective study aimed to evaluate the prognostic value of magnetic resonance imaging (MRI) parameters and neutrophil-to-lymphocyte ratio (NLR) in LARC patients with pCR.MethodsBetween 2015 and 2019, 180 LARC patients who achieved pCR after NCRT and surgery were included. MRI parameters and NLR were evaluated as potential predictors for 5-year overall survival (OS) and disease-free survival (DFS) using the Kaplan-Meier and COX regression analysis.ResultsWith a median follow-up time of 68.3 months, the 5-year OS and DFS rates were 94.2% and 91.4%, respectively. Thirteen patients (7.2%) died, 2 (1.1%) experienced local recurrence, and 15 (8.3%) experienced distant metastases. Pretreatment MRI parameters and NLR were correlated with 5-year OS and DFS in pCR patients in the univariate analysis. The multivariate analysis identified baseline EMVI and NLR as independent predictors for 5-year OS and DFS (all P < .05). Patients in the low-risk group (EMVI-negative and/or NLR ≤ 2.8, n = 159, 88.3%) had a more favorable 5-year DFS compared to those in the high-risk group (EMVI-positive and NLR > 2.8, n = 21, 11.7%) (95.6% vs 59.4%, P < .001), with similar findings for 5-year OS (97.4% vs 70.6%, P < .001).ConclusionsThis study showed that MRI parameters and NLR were associated with long-term prognosis in patients with pCR. These findings could aid in stratifying pCR patients and guide subsequent treatment and follow-up strategies.

IntroductionNanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) is an established second-line therapy for metastatic pancreatic ductal adenocarcinoma (PDAC). We previously developed a prognostic model (CGMH nomogram) to predict overall survival (OS) in patients receiving second-line chemotherapy before the nal-IRI + 5-FU/LV era. Herein, we aimed to validate the CGMH nomogram in a real-world cohort treated with nal-IRI plus 5-FU/LV, the current standard second-line treatment for metastatic PDAC.MethodsA retrospective cohort of 148 patients with metastatic PDAC treated with second-line nal-IRI + 5-FU/LV was analyzed. Prognostic scores were assigned using the CGMH nomogram, with patients stratified into tertiles as good, intermediate, and poor prognostic groups. Predictive performance was assessed using the concordance index (c-index) and calibration plots.ResultsOur cohort had a median OS of 6.1 months. Patients in the good, intermediate, and poor prognostic groups had median OS of 8.7 (95% confidence interval [CI], 6.7-10.7), 5.7 (95% CI, 5.3-6.3), and 4.0 (95% CI, 2.8-5.2) months, respectively. Compared with the good group, intermediate and poor groups had hazard ratios of 1.99 (95% CI, 1.29-3.07, P = .002) and 3.18 (95% CI, 1.87-5.40, P < .001), respectively. The nomogram demonstrated strong predictive ability, with c-indices of 0.73 and 0.70 for 6- and 12-month OS predictions, respectively. Calibration plots displayed excellent agreement between predicted and observed survival.ConclusionThe CGMH nomogram reliably predicted survival outcomes in nal-IRI + 5-FU/LV-treated patients with metastatic PDAC, and validation supported its use in clinical decision-making and personalized treatment planning.
