Outcomes of Microscopic Residual Tumor after Curative-Intent Surgery in Adenocarcinoma of Esophagogastric Junction

Objective: Radical surgery is the mainstay treatment for adenocarcinoma of the esophagogastric junction. The presence of microscopic residual tumor tissue after curative-intent surgery is associated with recurrence. This study compared the outcomes of patients with microscopic residual tumor (Residual+ group) and those without microscopic residual tumor (Residual- group). Material and Methods: We retrospectively reviewed the medical records of 71 patients with adenocarcinomas of the esophagogastric junction who underwent curative-intent surgery between January 2005 and August 2018. We evaluated the clinical and pathological characteristics and compared recurrences, rates and patterns, between groups. Five-year overall survival (OS) and 3-year disease-free survival (DFS) were analyzed by Kaplan-Meier analysis. Results: Nineteen (26.8%) patients had microscopic residual tumors, consisting of 8 (11.3%) with positive resection margins, 10 (14.0%) with malignant cells from peritoneal washing fluid cytology, and 1 (1.4%) with both. The median OS in the Residual- group was significantly better than that in the Residual+ group (31.3 vs 11.9 months, P = 0.003). The Residual- group had better 5-year OS (26.2% vs 11.9%, P = 0.015) and 3-year DFS (24.4% vs 9.8%, P = 0.003) than the Residual+ group. During follow-up period, 48% of the patients in the Residual+ group experienced recurrent disease, with a median follow-up time at 7.7 months. Distant metastasis was the most common site of recurrence. Conclusion: Microscopic residual tumor after resection is associated with poorer survival outcomes and higher recurrence rates. Curative surgery should aim to achieve R0 resection in all patients with resectable adenocarcinomas of the esophagogastric junction.

Survival Benefits of Postoperative Chemotherapy in Patients With Colorectal Mucinous Adenocarcinoma: An Analysis Utilizing Propensity Score Matching From the Surveillance, Epidemiology, and End Results Database.

This study aimed to investigate the characteristics of patients with colorectal mucinous adenocarcinoma (MAC) who benefit from postoperative chemotherapy (POCT) and to develop effective postoperative survival nomograms for predicting overall survival (OS) in colorectal MAC patients. Data of colorectal MAC patients who underwent surgery from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2020 were collected. Patients were grouped based on POCT, and intergroup analysis was performed using 1:1 propensity score matching (PSM). Kaplan-Meier (K-M) curves were used to compare the prognosis between the 2 groups. Cox analysis was employed to identify factors associated with OS in patients with colorectal MAC who underwent POCT. The variance inflation factor (VIF) and bilateral stepwise regression were used to determine factors included in the model. Additionally, a nomogram was constructed to predict postoperative survival outcomes for patients. The discriminative ability of the nomograms was evaluated using the C-index and calibration curve analysis, the decision curve analysis (DCA) assessed the clinical utility of the nomogram, and the receiver operating characteristic (ROC) curve evaluated the nomograms' performance. This study encompassed 6829 patients with colorectal MAC, among whom 2258 received POCT, and 4571 did not. Whether pre or post PSM, patients in the POCT group consistently exhibited a superior median OS compared to those in the postoperative non-chemotherapy group (P < .0001). For colorectal MAC patients undergoing POCT, OS was correlated with factors such as patient age, carcinoembryonic antigen levels, tumor deposits, perineural invasion (PNI), lymph node examination count, T staging, and Grade staging. Notably, a significant chemotherapy advantage was observed in patients without perineural invasion, those with lymph node examination counts exceeding 12, and patients with moderately differentiated tumors. The overall colorectal MAC patient postoperative OS predictive nomogram demonstrated a C-index of .74, with a calibration curve near the diagonal and a DCA curve indicating positive net benefits. In comparison to TNM staging, the ROC curves of the nomogram at 1 year, 3 years, and 5 years demonstrated superior predictive capabilities (AUC: .80 vs .71, .78 vs .71, .77 vs .70). This study revealed the characteristics of colorectal MAC patients who benefit from POCT and established effective prognostic nomograms, which can aid clinicians in designing personalized treatment plans for individual patients and promote precision medicine.

Growth and Survival Outcomes for Immature Gopher Tortoises in Contrasting Habitats: A Test of Drone-Based Habitat Assessment.

Juvenile growth rate is a critical demographic parameter, as it shortens the time to maturity and often dictates how long individuals remain vulnerable to predation. However, developing a mechanistic understanding of the factors determining growth rates can be difficult for wild populations. The gopher tortoise (Gopherus polyphemus) is an ecosystem engineer threatened by habitat loss and deficient management of pinelands in the southeastern United States. We investigated the factors governing immature gopher tortoise growth and explored the use of drone-based imagery for habitat assessment by comparing predictive models based on ground-based plant surveys versus drone-derived data. From 2021 to 2022, we tracked and measured immature tortoises in native sandhill and human-modified, ruderal habitat in south-central Florida. Using quarterly, high-resolution drone imagery, we quantified plant cover types and vegetation indices at each occupied burrow and measured the frequency of occurrence of forage species by hand. Annual growth rates of immature tortoises in ruderal habitat were higher than those in sandhill and were the highest published for this species. Models based on drone-derived data were able to explain similar proportions of variation in growth as ground-collected measures of forage, especially during the late dry season when both types of models were most predictive. Habitat differences in forage nitrogen content were also more pronounced during this season, when dominant ground cover in ruderal habitat (bahiagrass) had much higher nitrogen content than dominant ground cover in sandhill (wiregrass). Despite concerns about potential growth-survival trade-offs, tortoises in ruderal habitat did not exhibit lower apparent survival. Our findings indicate that habitat dominated by nutritious non-native grass can provide a valuable supplement to native sandhill through the mechanism of increased growth rates due to higher forage quality. Finally, our study demonstrates that drone technology may facilitate management by providing less labor-intensive ways to assess habitat quality for this and other imperiled herbivores.

Peritoneal recurrence in gastric cancer after curative gastrectomy: risk factors and predictive score model

Peritoneal recurrence (PR) remains the most common pattern of relapse in gastric cancer (GC), even after curative resection. Given its dismal prognosis, the identification of risk factors for PR is essential for developing new treatment modalities and selecting a more appropriate subgroup of patients. This study aimed to evaluate the risk factors and survival outcomes of patients with GC who had PR and to develop a risk score to predict PR. All patients with GC who underwent curative gastrectomy were included. For analysis, patients were divided into no recurrence (NR), recurrence in other sites (ROS), and PR. Risk factors for PR were analyzed to build a risk score. Among 622 patients with GC, 460 (74.0%) had NR, 98 (15.7%) had ROS, and 64 (10.3%) had PR. Female patients, linitis on computed tomography, depth of tumor invasion, and diffuse/mixed type were associated with PR. Patients with PR had worse overall survival than those with ROS (22.0 vs 29.8 months, respectively; P=.008). The median survival estimates after recurrence were 5.0 months in the PR group and 9.9 months in the ROS group (P<.001). The scoring system developed with 8 variables had an accuracy of 81% in predicting PR. Accordingly, 385 patients (61.9%) were classified as low risk, and 237 patients (38.1%) were classified as high risk. Among the 64 patients with PR, 53 (82.8%) were correctly classified as high risk (P<.001). Patients with PR had distinct clinicopathologic characteristics and extremely restricted survival compared with patients with recurrence in other sites. The risk-scoring model was able to identify patients at higher risk of PR.

Predictive genomic and transcriptomic analysis on endoscopic ultrasound-guided fine needle aspiration materials from primary pancreatic adenocarcinoma: a prospective multicentre study

We apply endoscopic ultrasound-guided fine needle aspiration biopsy to cytopathologically diagnose and sample nucleic acids from primary tumours regardless of the disease stage. 397 patients with proven pancreatic adenocarcinoma were included and followed up in a multicentre prospective study. DNA and mRNA were extracted from materials of primary tumours obtained by endoscopic ultrasound-guided fine needle aspiration biopsy and analysed using targeted deep sequencing and RNAseq respectively. The variant allele frequency of the KRAS mutation was used to evaluate the tumour cellularity, ranging from 15 to 20% in all cells, regardless of the tumour stage. The molecular profile of metastatic primary tumours significantly differed from other types of tumours, more frequently having TP53 mutations (p=0.0002), less frequently having RNF43 mutations, and possessing more basal-like mRNA component (p=0.001). Molecular markers associated with improved overall survival were: mutations in homologous recombination deficiency genes in patients who received first-line platinum-based chemotherapy (p=0.025) and wild-type TP53 gene in patients with locally advanced tumours who received radio-chemotherapy (p=0.01). The GemPred transcriptomic profile was associated with a significantly better overall survival in patients with locally advanced or metastatic pancreatic cancer who received a gemcitabine-based first-line treatment (p=0.019). The combination of genomic and transcriptomic analyses of primary pancreatic tumours enables us to distinguish metastatic tumours from other tumour types. Our molecular strategy may assist in predicting overall survival outcomes for platinum or gemcitabine-based chemotherapies, as well as radio-chemotherapy.

Biomarker Study for Selecting Neoadjuvant Chemotherapy Regimens Based on Prognostic Prediction Using Gastric Cancer Biopsy Specimens from a Phase II Randomized Controlled Trial.

The randomized phase II COMPASS trial revealed that neither the regimen nor the number of courses of preoperative neoadjuvant chemotherapy (NAC) for locally advanced gastric cancer (GC) significantly influence overall survival (OS). However, the impact of NAC regimens on OS may vary from patient to patient. The aim of this study was to identify biomarkers that can predict more appropriate individualized NAC regimens for improved prognosis using biopsy specimens from the COMPASS trial. RNA was extracted from endoscopic biopsy specimens of primary tumors obtained prior to NAC and real-time PCR analysis of 127 genes was conducted to identify those significantly affecting survival in the context of specific NAC regimens. THBS1, MSI1, and IGF2BP3 were identified as significant factors for stratifying survival among different NAC regimens, with statistically significantly interaction p values. Immunohistochemical analysis confirmed that the protein levels of THBS1, MSI1, and IGF2BP3 strongly correlated with their gene expression levels, validating these proteins as reliable biomarkers. This study effectively identified THBS1, MSI1, and IGF2BP3 as promising biomarkers for personalizing NAC regimens in patients with locally advanced GC. By tailoring NAC based on these biomarkers, it is possible to enhance survival outcomes and advance personalized treatment strategies. The findings underscore the potential for incorporating biomarker-guided approaches into clinical trials, aiming to refine and optimize NAC regimens for improved patient-specific treatment efficacy.

Efficacy and Safety of Nivolumab With Ipilimumab in Elderly Patients With Advanced Renal Cell Carcinoma.

Nivolumab and ipilimumab (NIVO+IPI) is standard therapy for patients with intermediate and poor risk advanced renal cell carcinoma (RCC). However, the efficacy and safety of NIVO+IPI in elderly patients aged >75 years remains unclear. This study aimed to determine the efficacy and safety of first-line NIVO+IPI treatment in patients aged >75 years with advanced RCC. This study included 59 patients with advanced RCC who received NIVO+IPI as first-line therapy between September 2018 and December 2023. Objective response rates (ORRs), along with progression-free survival (PFS) and overall survival (OS) were compared between patients aged <75 years and ≥75 years, to assess survival outcomes. A total of 46 (78.0%) and 13 (22.0%) patients were classified into <75 years and ≥75 years groups, respectively, at NIVO+IPI initiation. The ORRs were 45.7% for <75 years and 53.8% for ≥75 years (p=0.2422). No significant differences in PFS (p=0.0729) were observed between groups. In contrast, patients aged ≥75 years had better OS than those aged <75 years (p=0.0212). However, no significant difference was observed in the OS between the two groups of patients with clear cell histology (p=0.0532). The incidence of immune-related adverse events higher than Grade 3 was not significantly different between the two groups (p=0.5016). NIVO and IPI combination therapy is both safe and efficacious in patients aged ≥75 years with advanced RCC.

Association between aspartate aminotransferase to alanine aminotransferase ratio and mortality in critically ill patients with congestive heart failure

Congestive heart failure (CHF) is a complex clinical syndrome that significantly impacts patient outcomes, especially in critically ill patients admitted to intensive care units (ICUs). The aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT), has also been reported as a risk factor of cardiovascular diseases. However, few studies investigated the correlations between the AST/ALT ratio and ICU mortality in critically ill patients with CHF. This study investigates the association between the baseline AST/ALT ratio measured within the first 24 h of ICU admission and 28-day ICU all-cause mortality in critically ill patients with CHF. This retrospective cohort study included 4869 critically ill patients with CHF from the eICU Collaborative Research Database. Patients were categorized into tertiles based on their AST/ALT ratio: Tertile 1 (0.13–0.97), Tertile 2 (0.97–1.50), and Tertile 3 (1.50–5.89). Univariate and multivariate Cox proportional hazards regression models were used to evaluate the association between the AST/ALT ratio and 28-day ICU all-cause mortality. Nonlinear threshold effects and subgroup analyses were conducted to assess the robustness of the findings. Kaplan-Meier survival curves were generated to compare survival probabilities across tertiles. Participants with higher AST/ALT ratios were older, had higher illness severity, and experienced worse clinical outcomes. In univariate analysis, the AST/ALT ratio was significantly associated with 28-day ICU mortality (HR: 1.24, 95% CI 1.13–1.37, P < 0.0001). This association remained significant in the fully adjusted multivariate model. The highest tertile of AST/ALT ratio was associated with a significantly higher risk of mortality compared to the lowest tertile across all models (HR: 1.48, 95% CI 1.07–2.03, P = 0.0162 in Model 4). A nonlinear relationship was observed, with a threshold identified at an AST/ALT ratio of 2.08. Below this turning point, the association remained strong (HR: 1.47, 95% CI 1.13–1.91, P = 0.0036), while above it, the association was no longer significant. Subgroup analyses revealed no significant interactions, indicating that the association between AST/ALT ratio and mortality was consistent across various patient characteristics. Survival analysis showed that patients in the highest tertile had the poorest survival outcomes (P < 0.0001). An elevated AST/ALT ratio within the first 24 h of ICU admission is independently associated with increased 28-day ICU all-cause mortality in critically ill patients with CHF.

Midterm Survival of Cementless Total Knee Arthroplasty with a Three-Dimensional Printed Metal-Backed Patellar Component from the American Joint Replacement Registry

IntroductionHistorically, metal-backed patellar components have shown high early failure rates due to fracture, lack of osseous integration, and polyethylene wear and dissociation. We aimed to describe the survival outcomes of cementless total knee arthroplasty (TKA) utilizing the first widely used additively manufactured 3-dimensionally printed metal-backed patellar component (AM-MBP) to compare these to other cementless as well as cemented TKA cohorts. MethodsThere were 35,087 primary cementless TKA procedures in patients ≥ 65 years of age that utilized the AM-MBP component during the calendar years 2012 to 2020 that were identified from the American Joint Replacement Registry (AJRR). This AM-MBP cohort was benchmarked against age-similar (≥65 years) cohorts representing all other cementless primary TKA with a patellar component (aggregate cementless, n = 10,755) and all cemented TKA with a patellar component (aggregate cemented, n = 550,908). Cumulative percent revision curves and hazard ratios for all-cause revision were estimated using Cox proportional hazards models that adjusted for age and sex. ResultsThe cumulative percent all-cause revision (95% confidence interval (CI)) at 7-year follow-up was 1.9% (1.7%, 2.1%; 1,051 at risk) for the AM-MBP and 2.5% (2.1%, 2.8%; 1,281 at risk) for other aggregated cementless. and 2.1% (2.1%, 2.1%; 105641 at risk) for the aggregate cemented group. The adjusted hazard ratio for revision comparing AM-MBP with aggregate cementless was 0.77 (0.64, 0.93; P = 0.007), indicating a 23% decreased risk of revision for the AM-MBP group compared with all other cementless TKAs with a patellar component in the AJRR, controlling for age and sex. ConclusionsThe improved survivability of primary cementless TKA with AM-MBP versus other cementless TKA suggests that the AM-MBP construct is durable in real-world use in the Medicare-eligible population (age ≥ 65 years) appears to be comparable to the average durability of other cementless constructs captured by the AJRR.

Paraaortic lymph node metastasis in endometrial cancer patients: a comprehensive analysis of rates, survival outcomes, and risk factors through systematic review and meta-analysis

IntroductionThis study aims to explore the incidence of different metastatic patterns in paraaortic lymph nodes and their corresponding survival outcomes in patients with endometrial cancer, as well as to identify the associated risk factors of such metastasis.Material and methodsPubMed, Embase, Cochrane Central Register of Controlled Trials, International Clinical Trials Registry Platform, and Clinical Trials.gov were searched from inception to February 10, 2024.The analysis was conducted using R version 4.2.3.ResultsA total of 47 studies involving 33,425 endometrial cancer patients were analyzed. Meta-analysis results revealed that the rate of isolated paraaortic lymph node metastasis, where pelvic lymph nodes were negative but paraaortic lymph nodes were positive (PLN-PAN+), was found to be 2.58% (95% CI 0.0195-0.0329). The rates for PLN+PAN- and PLN+PAN+ were notably higher at 8.54% (95% CI 0.0642-0.1092) and 8.37% (95% CI 0.0613-0.1090), respectively. For clinical stage I EC, the occurrence rate was 5.92% for PLN+PAN- (95% CI 0.0258-0.1032), 1.00% for PLN-PAN+ (95% CI 0.0081-0.0120), and 2.99% for PLN+PAN+ (95% CI 0.0188-0.0431). The survival outcomes indicate a decreasing trend from the PLN-PAN+ and PLN+PAN- groups to the PLN+PAN+ group. Additionally, the survival outcomes of patients with isolated paraaortic lymph node metastasis appear to be comparable to, or not inferior to, those of the PLN+PAN- group. The analysis indicated that pelvic lymph node metastasis (OR 16.72, 95% CI 10.03-27.86), myometrial invasion ≥50% (OR 5.18, 95% CI 3.09-8.69), lymph-vascular space invasion (LVSI) (OR 3.46, 95% CI 2.49-4.81), cervical invasion (OR 4.00, 95% CI 2.09-7.66), and non-endometrioid cancer (OR 2.39, 95% CI 1.17-4.86) were risk factors for paraaortic lymph node metastasis.ConclusionsIsolated paraaortic lymph node metastasis, though relatively rare, can still occur even in clinical stage I endometrial cancer. The survival outcomes of patients with isolated paraaortic lymph node metastasis appear to be comparable to, or not inferior to, those of the PLN+PAN- group. Even in patients with negative pelvic lymph nodes, careful consideration should be given to the possibility of paraaortic lymph node metastasis, especially in those with high-risk factors.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42024503959.

Survival Outcomes of an Early Intervention Smoking Cessation Treatment After a Cancer Diagnosis

Smoking after a cancer diagnosis increases mortality and risk for a second cancer. To determine the association between time of entry into a smoking cessation intervention following a cancer diagnosis and survival outcomes. Using a prospective cohort study design, patients with cancer who smoked and received cessation treatment were assessed at 3 months, 6 months, and 9 months following tobacco treatment onset. Survival outcomes of tobacco treatment were measured and compared among patients at the MD Anderson Cancer Center Tobacco Research and Treatment Program. Treatment occurred between January 1, 2006, and March 3, 2022. Patients were excluded if they died before the tobacco treatment ended, received their diagnosis more than 6 months after beginning cessation treatment, or lacked staging information. The data analysis took place from September 2023 to May 2024. Cessation treatment consisted of 6 to 8 personalized counseling visits and 10 to 12 weeks of pharmacotherapy. More than 95% of visits were provided via telemedicine. The primary outcomes were survival as recorded in the MD Anderson Cancer Center tumor registry and 7-day point prevalence abstinence at each follow-up. The main analytical sample consisted of 4526 currently smoking patients diagnosed with cancer and receiving cessation treatment (2254 [49.8%] female; median [IQR] age, 55 [47-62] years). Survival over 15 years increased for those quitting smoking at 3 months (adjusted hazard ratio [aHR], 0.75 [95% CI, 0.67-0.83]), 6 months (aHR, 0.79 [95% CI, 0.71-0.88]), and 9 months (aHR, 0.85 [95% CI, 0.76-0.95]) of follow-up. The optimal survival outcomes were observed for patients who received tobacco treatment within 6 months of a cancer diagnosis. At the 75th percentile, their survival increased from 2.1 years (95% CI, 1.8-2.4 years) among continuing smokers (nonabstainers) vs 3.9 years (95% CI, 3.2-4.6 years) for patients who quit (abstainers). Similar but less pronounced outcomes were noted when tobacco treatment began within 6 months to 5 years following diagnosis, with survival at the 75th percentile of 4.8 years (95% CI, 4.3-5.3 years) for nonabstainers vs 6.0 years (95% CI, 5.1-7.2 years) for abstainers. The results of this prospective cohort study suggest that evidence-based smoking cessation treatment within 6 months following a cancer diagnosis maximizes survival benefit. This study supports smoking cessation as an important early clinical intervention for patients after being diagnosed with cancer.

Improving postoperative survival in cholangiocarcinoma: development of surgical strategies with a screening program in the epidemic region

BackgroundThe Cholangiocarcinoma Screening and Care Program (CASCAP) has been launched since 2013 to detect early-stage cholangiocarcinoma and reduce the disease death. However, the clinical utility of the CASCAP remains unclear. To compare survival outcomes between two time periods: before and after 2013, when significant changes in treatment strategies were implemented, and to evaluate the efficacy of the ultrasound-based screening program, in an Asian region endemic for cholangiocarcinoma.MethodsA single-center retrospective review was conducted in curative-intended resection cholangiocarcinoma from 2002 to 2021. Patents characteristics and survival outcomes were compared between 2002 and 2013 (early period) and 2014 to 2021 (later period).ResultsA total of 1091 patients with intrahepatic (n = 624) or perihilar (n = 467) cholangiocarcinoma was included (early period, n = 658; later period, n = 433). Of 66 (15.2%) patients in the later period were referred by the CASCAP. The incidence of early-staged disease (Stage 0 and 1) was lower in early period compared to later period 16.0% versus 29.1% (p < 0.001); that of positive surgical margin was higher in early period 53.7% versus 40.0% (p < 0.001). A median survival time (MST) was 14 months in early and 40 months in later period (p < 0.001). Subgroup analysis by tumor location, the MST was 13 versus 60 months in early and late periods for intrahepatic tumor (p < 0.001), respectively. While MST in perihilar tumor was 18 versus 31 months in early and late periods(p < 0.001), respectively. By presentation, the MST was 51 vs. 38 months, respectively, with screening and usual presentation (p = 0.06).ConclusionPostoperative survival in CCA patients improved more than doubled during the study period. Moreover, the late period demonstrated enhanced early-stage detection, a higher rate of negative surgical margins, and improved survival outcomes.

Differential expression of ORAI channels and STIM proteins in renal cell carcinoma subtypes: implications for metastasis and therapeutic targeting.

Renal cell carcinoma (RCC) presents significant clinical challenges, highlighting the importance of understanding its molecular mechanisms. While store-operated Ca2+ entry (SOCE) is known to play an essential role in tumorigenesis and metastasis, its specific implications across various RCC subtypes remain underexplored. This study analyzed SOCE-related mRNA profiles from the KIRC and KIRP projects in The Cancer Genome Atlas (TCGA) database, focusing on differential gene expression and overall survival outcomes. Functional studies in clear cell RCC (Caki-1) and papillary RCC cell lines (pRCC, Caki-2) revealed increased expression of Orai1 and Orai3, along with STIM1, exhibited in both subtypes, with decreased STIM2 and increased Orai2 expression in pRCC. Notably, Orai3 expression had a gender-specific impact on survival, particularly in females with pRCC, where it inversely correlated with STIM2 expression. Functional assays showed Orai3 dominance in Caki-2 and Orai1 in Caki- 1. Interestingly, 2-APB inhibited SOCE in Caki-1 but enhanced it in Caki-2, suggesting Orai3 as the primary SOCE channel in pRCC. Knockdown of Orai1 and Orai3 reduced cell migration and proliferation via regulating focal adhesion kinase (FAK) and Cyclin D1 in both cell lines. These findings highlight the critical roles of Orai1 and Orai3 in RCC metastasis, with Orai3 linked to poorer prognosis in females with pRCC. This study offers valuable insights into RCC diagnostics and potential therapeutic strategies targeting ORAI channels and STIM proteins.

Efficacy and safety of surufatinib in the treatment of patients with neuroendocrine tumor: a real-world study in Chinese population

BackgroundNeuroendocrine tumors (NETs) are rare neoplasms that originate from peptidergic neurons and neuroendocrine cells. Due to their increasing incidence, effective treatment strategies are required. Surufatinib, a novel small-molecule inhibitor with antiangiogenic and immunomodulatory effects, has shown promise in clinical trials for advanced NETs. However, the efficacy and safety of surufatinib are influenced by multiple factors, and there is currently a lack of sufficient real-world studies to explore these potential influencing factors.MethodsWe conducted a retrospective study on 133 patients with NETs who were treated with surufatinib at Sun Yat-sen University Cancer Center. Patients were histologically confirmed to have primary NETs. Statistical analyses, including Cox regression models and Kaplan-Meier curves, were conducted to assess the impact of the primary tumor site on progression-free survival (PFS) and overall survival (OS).ResultsPatients with gastroenteropancreatic NETs (GEP-NETs) exhibited significantly longer PFS and OS compared to extraGEP-NETs patients. Subgroup analyses also revealed variations in survival outcomes among patients with liver metastases depending on the primary tumor site. Adverse events (AEs), including proteinuria and increased bilirubin, were more common in GEP-NETs patients. These findings emphasize the importance of considering primary tumor site in treatment decisions for NETs.ConclusionsPrimary tumor site is a critical factor influencing the efficacy of surufatinib in NETs. Clinicians should consider this factor when determining treatment strategies.

Hispanic Breast Cancer Survivors Share Their Perceptions About Endocrine Blocking Therapy Adherence

Breast cancer is the leading cause of cancer-related mortality among Hispanic women in the U.S., despite a lower incidence compared to non-Hispanic White women. Hispanic women often face unique socio-economic and cultural barriers that impact timely diagnosis, treatment, and survival outcomes. Hormone receptor-positive breast cancer is prevalent in this population, with endocrine blocking therapy (EBT) recommended as a standard treatment. However, Hispanic breast cancer survivors exhibit higher rates of EBT non-adherence, influenced by factors such as side effects, medication access, and patient-provider communication. This study investigates the perceptions of Hispanic breast cancer survivors on EBT use and identifies factors contributing to adherence challenges, aiming to address disparities and improve outcomes.

The role of PD-L1 in patients with non-small cell lung cancer receiving neoadjuvant immune checkpoint inhibitor plus chemotherapy: a meta-analysis

Background: The use of immune checkpoint inhibitors (ICIs) as neoadjuvant therapy is a promising novel approach in resectable non-small-cell lung cancer (NSCLC). This study aimed to investigate the prognostic value of PD-L1 in patients with NSCLC receiving neoadjuvant immune checkpoint inhibitor plus chemotherapy (CT). Materials and methods: Several databases (PubMed, Embase, and cochrane central register of controlled trials [CENTRAL]) were systematically searched. Randomized controlled trials (RCTs) investigating pathological and survival outcomes with neoadjuvant ICI + CT versus CT alone in NSCLC were analyzed. Results: Overall, eight RCTs (n = 3,404) were included. The analyses showed neoadjuvant ICI + CT significantly improved complete pathological response (pCR) and event-free survival (EFS) in either tumor PD-L1 < 1%, ≥ 1%, 1-49%, or ≥ 50% population (both p < 0.0001) compared with neoadjuvant CT alone. The overall survival (OS) data are not yet mature among all included RCTs, and only three RCTs presented OS data by PD-L1 status of patients. The pooled OS favored neoadjuvant ICI + CT in the PD-L1 ≥ 1% population (hazard ratio [HR], 0.45; 95% CI, 0.31–0.65; p < 0.0001), but not in the PD-L1 < 1% population (HR, 0.89; 95% CI, 0.66–1.19; p = 0.43). Conclusions: Compared with neoadjuvant CT alone, neoadjuvant ICI + CT significantly enhanced pCR and EFS for patients with resectable NSCLC regardless of the expression of PD-L1. It seems that only patients with PD-L1 positive tumors may achieve a better OS, but it’s currently inconclusive due to immature data, so future research with long-term follow-up is still needed.

High Prevalence of MYD88 and CD79B Mutations in Primary Sinonasal Diffuse Large B-Cell Lymphoma: Identification of an MCD-like Subtype.

Primary sinonasal diffuse large B-cell lymphoma (PSDLBCL) is a rare aggressive lymphoma. Recently, genetic classification using Next Generation Sequencing (NGS) demonstrated that PSDLBCL largely consists of the MCD genotype, which has a poor prognosis mainly driven by MYD88 L265P and CD79B gene abnormalities. This study investigated the prevalence and clinicopathological significance of MYD88 L265P and CD79B Y196 mutations using droplet digital PCR in 55 patients with PSDLBCL, as well as the translocation of BCL2/BCL6/c-Myc with FISH. We found mutations in MYD88 L265P (29/55, 52.7%) and CD79B Y196 (20/55, 36.4%). The MCD-like subtype, defined by the mutation of MYD88 and/or CD79B, was found in 32 out of 55 cases (58.2%). This subtype largely consists of non-GCB type (31/32, 96.9%; P<0.01) and double-expressor cases (20/32, 62.5%; P=0.01) compared with the MYD88/CD79B co-wild type, with BCL6 translocation in a small subset (2/32, 6.3%) and no translocations of BCL2 (0/32) or c-Myc (0/32). The MCD-like subtype tended to relapse in specific sites such as the central nervous system, testis, and/or skin compared with the co-wild type (P=0.03), showing poorer outcomes in overall survival (P=0.02) and progression-free survival (P=0.01). In conclusion, our study highlights a high prevalence of MYD88 and CD79B mutations in PSDLBCL, identifying an aggressive MCD-like subtype with a distinct relapse pattern. This molecular subclassification can be helpful for both prognostic prediction and therapeutic strategy in patients with PSDLBCL.
