Real-world prevalence, treatment and survival of "high risk" early breast cancer, with mandatory testing of gBRCA1/2 mutation according to the OlympiA trial inclusion criteria: Data from a population-based registry.

BACKGROUND: The results of the OlympiA study led to the approval of a PARP inhibitor (olaparib) as adjuvant treatment for early breast cancer (eBC) at high risk of relapse in patients with a germline BRCA1/2 mutation (gBRCAm). However, the proportion of patients in routine practice who meet the "high-risk" criteria applied in the OlympiA study, and for whom gBRCAm testing would now be mandatory, remains unknown. PATIENTS AND METHODS: In this population-based study, we use unique data from the French specialized Côte d'Or Breast and Gynecological Cancer Registry, to assess the real-life proportion, and long-term prognosis of patients treated for eBC between 2005 and 2015 with standard treatment, and at "high risk" of relapse according to the OlympiA trial criteria. RESULTS: We included 3483 patients treated for HER2-negative eBC (N = 380 with ER-, and N = 3103 with ER + tumor). We found N = 62 (1.8 %) patients with gBRCA1/2 mutations. A total of 494 patients (14.2 %) were classified as "high risk" according to the Olympia criteria; 55 % with ER-tumors, and 9.1 % with ER + tumors, respectively. Despite more intensive systemic treatments in "high risk" patients, 10-year overall survival was much worse in these "high risk" patients compared to the others: 60.1 % vs 83.8 % in ER-tumors, and 55.4 % vs 84.1 % in ER + tumors. Our estimates of net survival show an even greater difference. CONCLUSION: This study provides real-life insights into the prevalence and prognosis of patients with high-risk eBC, in a context where the approval of adjuvant olaparib requires careful reorganization of care, so as not to overlook a patient with gBRCAm who could benefit from adjuvant olaparib.

A new therapeutic strategy for infectious diseases against intracellular multidrug-resistant bacteria.

Bacterial infections result in 7,700,000 deaths per year globally, with intracellular bacteria causing repeated and resistant infection. No drug is currently licenced for the treatment of intracellular bacteria. A new screening platform mimicking the host milieu has been established to explore phytochemical antibiotic adjuvants. Previously neglected isoprenylated flavonoids were found to be effective against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Specifically, the synergistic effect between glabrol and streptomycin against intracellular bacteria was observed for the first time. The glabrol-streptomycin combination targets bacterial inner membrane phospholipids, disrupts arginine biosynthesis, inhibits cell wall proteins and biofilm formation genes (agrA/B/C/D), and promotes ROS production, causing subsequent membrane and wall damage. To enhance the selective uptake of combination drug into infected cells, hyaluronic acid-streptomycin-lipoic acid-glabrol nanoparticles (HSLGS-S) were designed and synthesized to trigger the intracellular delivery of the glabrol-streptomycin combination. Thus, the treatment can be transported into the infected intracellular region and selectively release the glabrol-streptomycin combination to the bacterial at site. The bioactivity of HSLGS-S in clearing intracellular bacteria was 20-fold higher than that of the glabrol-streptomycin combination alone in vitro and 2- to 10-fold higher in vivo.

Acidified sucralfate encapsulated chitosan derivative nanoparticles as oral vaccine adjuvant delivery enhancing mucosal and systemic immunity.

Oral vaccines are generally perceived to be safe, easy to administer, and have the potential to induce both systemic and mucosal immune responses. However, given the challenges posed by the harsh gastrointestinal environment and mucus barriers, the development of oral vaccines necessitates the employment of a safe and efficient delivery system. In recent years, nanoparticle-based delivery has proven to be an ideal delivery vector for the manufacture of oral vaccines. Hence, considering the above, the sucralfate acidified (SA) encapsulated N-2-Hydroxypropyl trimethyl ammonium chloride chitosan (N-2-HACC)/N,O-carboxymethyl chitosan (CMCS) nanoparticles (SA@N-2-HACC/CMCS NPs) were prepared, and the BSA was used as a model antigen to investigate the immune responses. The SA@N-2-HACC/CMCS NPs had a particle size of 227 ± 7.0 nm and a zeta potential of 8.43 ± 2.62 mV. The NPs displayed slow and sustained release and high stability in simulated gastric juice and intestinal fluid. RAW 264.7 macrophage-like cell line demonstrated enhanced uptake of the SA@N-2-HACC/CMCS/BSA Nps. The vaccine via oral administration markedly enhanced the residence time of BSA in the intestine for more than 12 h and elicited the production of IgG and sIgA. The SA@N-2-HACC/CMCS NPs developed here for oral administration is an excellent technique for delivering antigens and provides a path of mucosal vaccine research.

Adjuvant chemoradiotherapy plus pembrolizumab for locally advanced esophageal squamous cell carcinoma with high risk of recurrence following neoadjuvant chemoradiotherapy: a single-arm phase II study.

BACKGROUND: Adjuvant nivolumab reduces recurrence in patients with locoregional esophageal cancer who had pathological residual disease after neoadjuvant chemoradiotherapy and R0 resection. However, the efficacy of adjuvant anti-PD-1 therapy in patients at higher risk of recurrence remains unclear. METHODS: This phase II trial (ClinicalTrials.gov identifier: NCT03322267) enrolled patients with locally advanced esophageal squamous cell carcinoma (ESCC) received neoadjuvant chemoradiotherapy plus esophagectomy but still had various risk factors for recurrence, such as involved or close margins (≤ 1 mm), extranodal extension of the involved lymph nodes, and the ypN2-3 stage. Patients received adjuvant therapy composed of a course of cisplatin-based chemoradiotherapy and pembrolizumab (200 mg, IV every 3 weeks) for 18 cycles. The primary endpoint was 1-year relapse-free survival (RFS) rate. RESULTS: Twenty-five patients were enrolled. The risk factors were tumor margins of ≤ 1 mm (18 patients), extranodal extension of the involved lymph nodes (9 patients), and the ypN2-3 stage (9 patients). The median follow-up duration was 21.6 months (95% CI: 18.7-33.2). The rate of 1-year RFS was 60.0%. The median duration of RFS and overall survival was 14.3 (95% CI: 9.0-19.5) and 21.6 (95% CI: 0.0-45.5) months, respectively. Treatment-emergent adverse events of any grade and those of ≥ 3 grade occurred in 56% and 8% of all patients receiving cisplatin-based chemoradiotherapy and in 79.2% and 12.5% of those receiving pembrolizumab. CONCLUSIONS: Adjuvant chemoradiotherapy followed by pembrolizumab is feasible and may be associated with improved 1-year RFS rate in patients at high risk of recurrence after trimodality therapy for locally advanced ESCC. Trial registration number ClinicalTrials.gov (No. NCT03322267).

Olanzapine vs. magnesium valproate vs. lamotrigine in anti-N-methyl-D-aspartic acid receptor encephalitis: a retrospective study.

BACKGROUND: This study aimed to compare the impact of olanzapine, magnesium valproate, and lamotrigine as adjunctive treatments for anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. And it is expected to add supporting points related to the rebalance of neurotransmitters in the brain through adjuvant therapy in the clinical management of anti-NMDAR encephalitis. METHODS: This retrospective study included patients diagnosed with anti-NMDAR encephalitis who received standardized immunotherapy at Hunan Brain Hospital between January 2018 and December 2020. RESULTS: Compared to the olanzapine group, both the magnesium valproate and lamotrigine groups showed lower scores on the positive and negative symptom scale (PANSS) total score after 3 weeks of treatment (all P < 0.05). The Montreal Cognitive Assessment Scale (MoCA) scores in the magnesium valproate and lamotrigine groups were significantly higher than in the olanzapine group after 3 weeks and 3 months of treatment (all P < 0.05). After 3 months of treatment, the proportions of patients with a modified Rankin scale score (mRS) of 0-1 in the magnesium valproate and lamotrigine groups were significantly higher than in the olanzapine group (all P < 0.05). The electroencephalogram (EEG) abnormality ranks at 3 months were significantly lower in the magnesium valproate and lamotrigine groups compared with the olanzapine group (all P < 0.05). Furthermore, the Glx/Cr ratio significantly decreased after 3 months of treatment (all P < 0.05) in the magnesium valproate and lamotrigine groups, while the Glx/Cr ratio in the olanzapine group showed no significant change (P > 0.05). CONCLUSION: Compared with olanzapine, the addition of magnesium valproate or lamotrigine to immunotherapy might be associated with a lower PANSS score, higher MoCA score, and lower mRS score. The improvement of neurological functions and cognitive function may be related to the decreased Glx/Cr ratio.

Synergistic immune augmentation enabled by covalently conjugating TLR4 and NOD2 agonists.

Enhancing the efficacy of subunit vaccines relies significantly on the utilization of potent adjuvants, particularly those capable of triggering multiple immune pathways. To achieve synergistic immune augmentation by Toll-like receptor 4 agonist (TLR4a) and nucleotide-binding oligomerization-domain-containing protein 2 agonist (NOD2a), in this work, we conjugated RC529 (TLR4a) and MDP (NOD2a) to give RC529-MDP, and evaluated its adjuvanticity for OVA antigen. Compared to the unconjugated RC529+MDP, RC529-MDP remarkably enhanced innate immune responses with 6.8-fold increase in IL-6 cytokine, and promoted the maturation of antigen-presenting cells (APCs), possibly because of the conjugation of multiple agonists ensuring their delivery to the same cell and activation of various signaling pathways within that cell. Furthermore, RC529-MDP improved OVA-specific antibody response, T cells response and the memory T cells ratio relative to the unconjugated mixture. Therefore, covalently conjugating TLR4 agonist and NOD2 agonist was an effective strategy to enhance immune responses, providing the potential to design and develop more effective vaccines.

Phase 1 trial of an investigational Tdap booster vaccine with CpG 1018 adjuvant compared with Boostrix in healthy adults and adolescents.

This phase 1 trial assessed the safety and immunogenicity of an investigational tetanus/diphtheria/acellular pertussis vaccine combined with CpG 1018 adjuvant 1500 µg (Tdap-1018 1500 µg) or 3000 µg (Tdap-1018 3000 µg) in adults and adolescents. In this randomized, active-controlled, multicenter, dose-escalation trial, healthy participants aged 10 to 22 years received 1 dose of Tdap-1018 1500 µg, Tdap-1018 3000 µg, or Boostrix. Geometric mean concentrations (GMCs) and booster response rates (BRRs) for antibodies against pertussis (pertussis toxin, filamentous hemagglutinin, pertactin), tetanus, and diphtheria antigens, and neutralizing antibodies against pertussis toxin were assessed 4 weeks after vaccination. Safety and tolerability were assessed for solicited post-injection reactions within 7 days after vaccination and unsolicited adverse events up to 12 weeks after vaccination. Of 117 enrolled participants, 80 adults (92%) and 30 adolescents (100%) completed the study. Both Tdap-1018 formulations were generally well tolerated, with no vaccine-related serious adverse events. Frequency and severity in post-injection reactions after Tdap-1018 administration were similar to Boostrix except for higher proportions of moderate pain for Tdap-1018. In adults at week 4, ratio of GMCs and BRRs for all antigens in the 3000-µg group were similar to or higher than Boostrix, with significantly higher GMC ratios for anti-pertussis toxin (2.1 [1.5-3.0]) and anti-tetanus (1.8 [1.1-2.9]) and significantly higher BRRs for anti-pertussis toxin (difference [95% CI]: 34.5% [13.4-54.6]), anti-pertactin (19.2% [4.4-38.1]), and anti-tetanus (30.0% [3.6-52.7]) antibodies. For adolescents, in the 3000-µg group, ratio of GMCs and BRRs were similar to or higher than Boostrix for all antigens. Both Tdap-1018 formulations showed acceptable safety and tolerability profiles. Tdap-1018 3000 µg induced similar or higher immune responses than Boostrix.

Identification of molecular subtypes for endometrial carcinoma using a 46-gene next-generation sequencing panel: a retrospective study on a consecutive cohort.

BACKGROUND: Traditional classification tools for endometrial carcinoma (EC), such as DNA sequencing, immunohistochemistry (IHC), or PCR, are cumbersome and time-consuming. Large next-generation sequencing (NGS) panels have simplified testing but are expensive. In this study, we propose a concise NGS panel as an effectively viable approach for classifying EC. MATERIALS AND METHODS: We retrospectively enrolled a consecutive EC cohort of hysterectomy with bilateral salpingo-oophorectomy from Fudan University Shanghai Cancer Center between 2020 and 2022. A 46-gene NGS panel was utilized to identify POLE exonuclease domain mutations, microsatellite instability-high (MSI-H), TP53 mutations, and other clinically relevant targets. RESULTS: Tumor tissue samples from 331 EC patients were evaluated, with 284 (85.8%) cases classified as endometrioid endometrial carcinoma. The median follow-up time was 32.6 months (n = 303), during which 23 patients experienced recurrence or disease progression. Using the concise NGS panel, patients were stratified into four molecular subgroups according to the World Health Organization classification criteria: POLE mut (n = 47; 14.2%), mismatch repair deficiency (dMMR) (n = 79; 23.9%), non-specific molecular profile (n = 148; 44.7%), and abnormal p53 expression (p53 abn) (n = 57; 17.2%). POLE mut displayed the most favorable prognosis, while p53 abn had the worst prognosis (P < 0.001). The concordance between NGS and IHC was 91.8% (269/293) for detecting MMR status and 65.3% (201/308) for detecting p53 status. Patients detected solely by NGS had significantly worse prognosis than those detected solely by IHC, indicating higher accuracy of the NGS panel. With the molecular subtyping information, adjuvant treatment plans for 19.6% of patients could potentially be altered, mainly concentrated in the POLE mut and p53 abn subtypes. This panel also aids targeted therapy and poly (ADP-ribose) polymerase (PARP) inhibitor-related gene mutation detection, as well as auxiliary genetic screening. CONCLUSION: Our study demonstrates that the concise NGS panel is an effective 'one-stop' strategy for precisely classifying EC with high clinical availability.

Case report on an extremely rare type of ependymoma arising from the thigh.

INTRODUCTION: Ependymomas are neuroepithelial neoplasms of the central nervous system that arise from the precursor cells lining the ventricular system and the central canal of the spinal cord. Herein, we report a case of an extremely rare type of ependymoma arising from the thigh. Then, a literature review was performed. PRESENTATION OF CASE: An 87-year-old female Japanese patient presented with a chief complaint of a mass on the medial aspect of her right thigh. Pathology revealed a grade 2 extra-neural ependymoma. PET-CT and brain MRI showed no neoplastic lesions in the central nervous system, and the tumor was localized only in the right thigh. The tumor was growing and was treated as a low-grade tumor with extensive resection and postoperative adjuvant radiotherapy. The patient has been alive for 3 years, without postoperative recurrence or complications. DISCUSSION: This case presents a rare extra-neural ependymoma of central nervous system origin arising in the thigh. The pathogenesis is unknown, but a search for neoplastic lesions in the cerebrospinal cord is warranted. Extra-neural ependymomas should be treated as low-grade tumors because they are more prone to recurrence and metastasis than ordinary ependymomas. CONCLUSION: We experienced an extremely rare extra-neural ependymoma arising in the thigh. A search for tumors in the central nervous system region of the cerebrospinal cord, previous literature, and clinical, imaging, and pathological findings should be consulted to determine a treatment strategy.

Return to Intended Oncological Therapy: State of the Art and Perspectives.

PURPOSE OF THE REVIEW: Despite advances in surgical procedures, cancer recurrence still affects a substantial proportion of patients for whom surgery is considered a curative therapy. This review aims to provide a comprehensive overview of RIOT, addressing its definition, influencing factors, and clinical implications. FINDINGS: RIOT can be defined as a continuous variable as the time from surgery to initiation of adjuvant therapies or categorically as whether patients can successfully receive adjuvant therapies or not. Factors influencing RIOT are age, sex, socioeconomic status, access to healthcare, physical performance and comorbidities, and quality of anesthesia and surgical care. Adjuvant therapies such as chemotherapy, radiotherapy, and immunotherapy are often administered to reduce the risk of recurrence after surgery and improve survival. Return to intended oncologic therapy (RIOT) has emerged as a promising outcome metric reflecting patients' functional recovery after surgery and their ability to receive adjuvant therapies.

Choice of Adjuvant Radiotherapy Facility in Sinonasal Squamous Cell Carcinoma.

OBJECTIVE: Undergoing surgery and adjuvant radiotherapy (aRT) at the same facility has been associated with higher overall survival (OS) in head and neck squamous cell carcinoma. Our study investigates whether undergoing surgery and aRT at the same academic facility is associated with higher OS compared with separate facilities in sinonasal squamous cell carcinoma (SNSCC). METHODS: The 2006 to 2017 National Cancer Database was queried for patients with SNSCC undergoing surgery at an academic facility followed by aRT with or without adjuvant chemotherapy. Multivariable binary logistic and Cox proportional hazards regression models were implemented. RESULTS: Of 419 patients satisfying inclusion criteria, 299 (71.4%) underwent surgery and aRT at the same academic facility. Residence in a less populated area (adjusted odds ratio [aOR] 1.75, 95% confidence interval [CI] 1.02-2.99, p = 0.042) and surgical facility case volume (aOR 2.51, 95% CI 1.21-5.21, p = 0.014) were associated with undergoing surgery and aRT at different facilities on multivariable logistic regression adjusting for patient demographics, clinicopathologic features, and adjuvant therapy (p < 0.05). Five-year OS was higher among patients undergoing surgery and aRT at the same academic facility (64% vs. 55%, p = 0.039). Undergoing surgery and aRT at different facilities remained associated with worse OS on multivariable Cox regression (aHR 1.90, 95% CI 1.09-3.32, p = 0.023). CONCLUSION: Undergoing surgery and aRT at the same academic facility is associated with higher OS in SNSCC. Academic physicians should carefully consider the recommendation of aRT treatment facility based on the level of benefit that the patient may derive from coordinated multidisciplinary care.

Tumor-Resident Microbiota-Based Risk Model Predicts Neoadjuvant Therapy Response of Locally Advanced Esophageal Squamous Cell Carcinoma Patients.

Few predictive biomarkers exist for identifying patients who may benefit from neoadjuvant therapy (NAT). The intratumoral microbial composition is comprehensively profiled to predict the efficacy and prognosis of patients with esophageal squamous cell carcinoma (ESCC) who underwent NAT and curative esophagectomy. Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis is conducted to screen for the most closely related microbiota and develop a microbiota-based risk prediction (MRP) model on the genera of TM7x, Sphingobacterium, and Prevotella. The predictive accuracy and prognostic value of the MRP model across multiple centers are validated. The MRP model demonstrates good predictive accuracy for therapeutic responses in the training, validation, and independent validation sets. The MRP model also predicts disease-free survival (p = 0.00074 in the internal validation set and p = 0.0017 in the independent validation set) and overall survival (p = 0.00023 in the internal validation set and p = 0.11 in the independent validation set) of patients. The MRP-plus model basing on MRP, tumor stage, and tumor size can also predict the patients who can benefit from NAT. In conclusion, the developed MRP and MRP-plus models may function as promising biomarkers and prognostic indicators accessible at the time of diagnosis.

Outcomes of adjuvant immune checkpoint inhibitor therapy in melanoma: a retrospective study.

BACKGROUND: Adjuvant treatment of malignant melanoma has improved the outcomes for patients. However, real-world data on efficacy and safety are limited. We investigated outcomes of melanoma patients treated with adjuvant immune checkpoint inhibitors (ICI) in the Ghent University Hospital. METHODS: Patients with melanoma (stage III-IV), who received at least one cycle of ICI as adjuvant treatment between 2018 and 2021 were included in this retrospective cohort study. Primary outcomes were recurrence-free (RFS) and overall survival (OS). Other outcomes of interest were relapse patterns and safety. RESULTS: 59 patients were included, with a median follow-up of 36 months. Disease recurrence or death of any cause was observed in 25/59 (42.4%) of the patients. The median RFS was 56.0 months (95%CI 36.1-75.9 months). At 48 months, RFS and OS were 55.9% and 84%, respectively. 9/23 (39%) recurrences were locoregional and 14/23 (60.9%) patients developed distant metastasis as first recurrence, including 2 (3.4%) with brain metastasis. Median time to recurrence was 9 months (range 2-56 months). 35/59 (59.3%) completed one year of adjuvant treatment, 12/59 (20.3%) stopped because of recurrence and 10/59 (16.9% because of toxicity. Immune-related adverse events wereseen in 29/59 (49.4%) patients, 10/59 (16.9%) developed grade 3-4 toxicity. CONCLUSION: This study confirms the real-world efficacy and safety of adjuvant ICI for melanoma, achieving RFS and OS comparableto the pivotal clinical trials. About 40% of patients develop arelapse, mainly during the adjuvant treatment. The outcomes ofpatients progressing during adjuvant ICI are poor, emphasizing the need of prospective and real-world studies on optimal management after progression on (neo)adjuvant treatment.

Seven-year analysis of adjuvant pembrolizumab versus placebo in stage III melanoma in the EORTC1325 / KEYNOTE-054 trial.

In the previously reported primary analyses of this phase 3 trial, 12 months of adjuvant pembrolizumab resulted in significantly longer recurrence-free survival (RFS) and distant metastasis-free survival (DMFS) than placebo in patients with resected high risk stage III melanoma. Stability of these benefits when the median follow-up was 3.5 and 5 years was published. Here we report results with a longer follow-up. METHODS: We randomized 1019 patients to receive pembrolizumab 200 mg or placebo, intravenously every 3 weeks for a total of 18 doses. RFS in the overall population and in the subgroup of patients with melanoma positive for the PD-1 ligand (PD-L1) were co-primary endpoints. DMFS in these two populations was a secondary and progression/recurrence-free survival 2 (PRFS2) an exploratory endpoint. RESULTS: The median follow-up was 6.9 years. In the overall intention-to-treat population, RFS was longer in the pembrolizumab group than in the placebo group (HR 0.63, 95 % CI 0.53 to 0.74). RFS at 7 years was 50 % (95 % CI 46 % to 55 %) in the pembrolizumab and 36 % (95 % CI 32 % to 41 %) in the placebo group. Positive effects were present both for loco-regional recurrences and distant metastases, and across substages IIIA-IIIB-IIIC, and PD-L1 positive and PD-L1 negative as well as for BRAF mutant and BRAF wild type populations. DMFS was longer in the pembrolizumab group than in the placebo group (HR 0.64, 95 % CI 0.54 to 0.76). DMFS at 7 years was 54 % (95 % CI 50 % to 59 %) in the pembrolizumab and 42 % (95 % CI 37 % to 46 %) in the placebo group. PRFS2 was longer in the pembrolizumab group than in the placebo group (HR 0.69, 95 % CI 0.57 to 0.84). PRFS2 at 7 years was 61 % (95 % CI 57 % to 66 %) in the pembrolizumab and 53 % (95 % CI 49 % to 57 %) in the placebo group. CONCLUSIONS: The 7-year analysis of adjuvant therapy with pembrolizumab demonstrated a sustained improvement in the long-term RFS, DMFS and PRFS2 compared with placebo in patients with resected stage III melanoma.

Adjuvant immunotherapy in high-risk muscle invasive urothelial carcinoma: A systematic review and meta-analysis of randomized clinical trials.

Despite surgical resection, many patients with muscle invasive urothelial carcinoma (MIUC) experience recurrence. Adjuvant immune checkpoint inhibition (ICI) following radical resection in patients with MIUC demonstrates disparate outcomes among phase III randomized controlled trials (RCTs). Our objective was to synthesize available data regarding the disease-free survival (DFS) benefit of adjuvant ICIs for patients with MIUC and evaluate the overall safety profile of ICIs in this setting. The protocol was registered with PROSPERO, CRD42022352587. We searched MEDLINE, Embase, CENTRAL, and relevant conference proceedings from inception up to January 29, 2024. Only phase III RCTs comparing adjuvant ICI versus placebo/observation were selected. Study screening and selection, along with data extraction was performed in duplicate according to a predefined registered protocol. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was used. Quality assessment was performed using the Cochrane risk-of-bias (RoB 2) tool for randomized trials. The primary and secondary endpoints were DFS and serious adverse events, respectively. All outcomes were analyzed using random-effects meta-analysis owing to inter-study heterogeneity. Sensitivity and subgroup analyses were performed to identify potential sources of heterogeneity. A priori defined subgroups of interest included positive program death-ligand 1 (PD-L1) expression, previous use of neoadjuvant chemotherapy (NAC), primary tumor origin, pathologic lymph node status, and baseline Eastern Cooperative Oncology Group performance status. Pooled results across the 3 RCTs (2,220 patients) demonstrated significantly improved DFS for patients treated with ICI in the intention-to-treat cohorts (HR 0.76, 95% CI 0.65-0.90). There was considerable clinical and statistical heterogeneity (I2 = 44%) due to differences in inclusion criteria and interventions. Overall, there was a low risk of bias among the RCTs. Regarding subgroup analyses, there was significant benefit among patients with negative PD-L1 expression (HR 0.76, 95% CI 0.64-0.90), those who received prior NAC (HR 0.69, 95% CI 0.52-0.91), and patients with lower tract (HR 0.71, 95% CI 0.55-0.92) but not upper tract disease (HR 1.21, 95% CI 0.87-1.68). This pooled analysis of DFS and safety provides support for ICI utilization in the setting of high-risk resected MIUC.

High expression of PAX8-AS1 correlates with poor prognosis and response to fluorouracil-based chemotherapy in stage II colon cancer.

Decisions regarding adjuvant therapy in patients with stage II colon cancer remains controversial and challenging. We aimed to determine novel biomarkers that help to predict relapse free survival (RFS) and identify a subset of patients with stage II colon cancer who could gain survival benefits from adjuvant chemotherapy. Public microarray datasets of stage II colon cancer samples were extracted from Gene Expression Omnibus database. Global gene expression changes were then analyzed between the paired early relapse and long-term survival group to identify the differentially expressed mRNAs and lncRNAs. Based on Lasso Cox regression modeling analysis, a total of 30 mRNAs and 2 lncRNAs were finally identified. With specific formula, stage II patients in training and validation sets were divided into low and risk groups with significantly different RFS. PAX8-AS1 is the novel lncRNA which showed the highest upregulation in early relapse group. Patients with high PAX8-AS1 expression level showed notably poorer RFS in both meta GEO cohort (P = 0.04, Figure 4B) and FUSCC cohort (P < 0.001, Figure 4C). Among the stage II patients with high PAX8-AS1 level, administration of fluorouracil-based adjuvant chemotherapy provided a substantial improvement in RFS (P = 0.002, Figure 3C). Further mechanistic study unveiled that PAX8-AS1 increases the response of CRC cells to chemotherapy in vitro and in vivo by maintaining the mRNA stability of PAX8. In conclusion, PAX8-AS1 as a novel and reliable biomarker for predicting prognosis and identification of patients with stage II disease who could gain survival benefit from fluorouracil-based adjuvant chemotherapy.

Motor improvement in Parkinson's disease patients receiving caffeine adjuvants: A double-blind randomized controlled trial in Indonesia.

Parkinson's disease (PD) manifests as a movement and brain function disorder characterized by symptoms such as resting tremors, rigidity, bradykinesia, and postural instability, leading to disability among patients. The use of psychostimulants such as caffeine has been associated with the improvement of motor symptoms in PD patients; however, studies regarding the effect of caffeine adjuvant therapy on motor function among PD patients in the Indonesian population are lacking. The aim of this study was to evaluate motor improvement as measured by the change in scores of the Movement Disorder Society - Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) among PD patients receiving caffeine adjuvant. A double-blind randomized controlled trial (RCT) was conducted among PD patients at Dr. Soetomo General Academic Hospital and Universitas Airlangga Hospital, Surabaya, Indonesia, from April to August 2023. A total of 27 patients were enrolled and randomly assigned to an intervention (receiving caffeine adjuvant, n=15) and control group (receiving placebo, n=12). Motor improvement was measured using the UPDRS III score prior to intervention and three weeks after. The Chi-squared test was used to analyze the difference in UPDRS III scores between the two groups. Motor improvement, as demonstrated by a reduction in the UPDRS III score, was observed in patients receiving caffeine adjuvant compared to those receiving placebo (80.0% vs 16.7%; p=0.004). Regarding the safety profile, only four out of 15 (26.6%) patients treated with caffeine reported minor adverse events. These conditions improved over time during the intervention. None of the 12 patients in the placebo reported adverse events. This study provides valuable insights into the initial dosage of caffeine that improves motor function in PD patients with minimum adverse effects.

How to Tackle Discordance in Adjuvant Chemotherapy Recommendations by Using Oncotype DX Results, in Early-Stage Breast Cancer.

BACKGROUND: The use of the Oncotype DX test reduces the rate of adjuvant chemotherapy recommendations. Few in-depth analyses have been performed on this decision-making process. METHODS: We retrospectively analyzed patient data based on available Oncotype DX test results (RS) irrespective of nodal status at a single center. We collected recommendations from six oncologists, first without RS (pre-RS) and then with RS results (post-RS). We investigated changes in recommendations, agreement between oncologist decisions, and the effect of different National Comprehensive Cancer Network (NCCN) recommendation categories (for, against, and considering chemotherapy). RESULTS: Data from 201 patients were included in the analysis. Recommendation of chemotherapy decreased by an average of 39.5%. Agreement improved substantially with RS, with a kappa value pre-RS of 0.37 (fair agreement) and post-RS of 0.75 (substantial agreement). Discordance remained substantial in cases where the NCCN recommendations considered chemotherapy only (32%). Pre-RS consensus against chemotherapy predicted low RS results (50 out of 51 patients). Post-RS consensus was highest in the NCCN chemotherapy recommendation group. CONCLUSIONS: The Oncotype DX test substantially improves decision accuracy in recommending adjuvant chemotherapy. It may be further improved with a consensus decision. In the case of pre-RS consensus against chemotherapy, the test can be spared.

Escalation and De-Escalation of Adjuvant Radiotherapy in Early Breast Cancer: Strategies for Risk-Adapted Optimization.

Postoperative radiotherapy (RT) is recommended after breast-conserving surgery and mastectomy (with risk factors). Consideration of pros and cons, including potential side effects, demands the optimization of adjuvant RT and a risk-adapted approach. There is clear de-escalation in fractionation-hypofractionation should be considered standard. For selected low-risk situations, PBI only or even the omission of RT might be appropriate. In contrast, tendencies toward escalating RT are obvious. Preoperative RT seems attractive for patients in whom breast reconstruction is planned or for defining the tumor location more precisely with the potential of giving ablative doses. Dose escalation by a (simultaneous integrated) boost or the combination with new compounds/systemic treatments may increase antitumor efficacy but also toxicity. Despite low evidence, RT for oligometastatic disease is becoming increasingly popular. The omission of axillary dissection in node-positive disease led to an escalation of regional RT. Studies are ongoing to test if any axillary treatment can be omitted and which oligometastatic patients do really benefit from RT. Besides technical improvements, the incorporation of molecular risk profiles and also the response to neoadjuvant systemic therapy have the potential to optimize the decision-making concerning if and how local and/or regional RT should be administered.
