Liver transplantation for HBV-related liver disease: impact of prophylaxis for HBV on HCC recurrence.

Background and aimsConflicting data exist regarding optimal prophylaxis for HBV recurrence (HBV-R) after liver transplantation (LT), particularly in patients with hepatocellular carcinoma (HCC). We assessed current practices for HBV-R prophylaxis in Italy, evaluating rates, risk factors, and clinical impact of HBV-R and HCC-R. MethodsMulticentric, retrospective study involving 20 Italian LT centers. All patients who underwent LT for HBV-related liver diseases between 2010 and 2021 were included. Logistic regression was used to identify predictors of HBV-R and HCC-R. Survival curves were estimated with Kaplan-Meier method and compared with log-rank test. ResultsWe included 1205 LT recipients (60.8% HCC). HBV prophylaxis was prescribed in 99.7% recipients, mostly with lifelong HBIG+NUCs (83.9%). Rates of HBV-R were 2.1% and 3.1% in patients transplanted without and with HCC, respectively. Median times from LT were 60 [9.5–77.5] and 5.5 [1–13] months, respectively. Recipients on lifelong HBIG+NUCs experienced lower rates of HBV-R than those in whom HBIG were withdrawn, used only during LT, or received NUCs alone (2.3% vs. 6.2% vs. 1.9% vs. 8%, respectively; p=0.042). In HCC recipients, HCC-R rate was 10.8% (median time from LT: 18 months). At multivariate analysis, HBV-R (OR: 10.329; 95%CI: 3.665-29.110), Child-Pugh C (OR: 3.519; 95%CI: 1.305-9.484), and microvascular invasion (OR: 3.088; 95%CI: 1.692-5.634) were independently associated with HCC-R. Five-year survival was lower in recipients who experienced HCC-R (32.5% vs. 92.4% in those who did not; p<0.001). ConclusionIn Italy, HBV prophylaxis is mostly based on lifelong HBIG+NUCs. HBV-R was rare and not associated with survival in patients transplanted for decompensated cirrhosis. In patients transplanted for HCC, HBV-R was independently associated with HCC-R. The clinical implications of these findings deserve further investigation.

Ulcerative Colitis Patients are at Increased Risk for Adverse Events Following Total Hip Arthroplasty

BackgroundPatients who have the autoinflammatory bowel disease ulcerative colitis (UC) may become candidates for total hip arthroplasty (THA). Having UC may predispose patients to postoperative adverse events, but it remains unclear if these events are related more to the disease process itself or perhaps related to the medications used to treat the condition. MethodsPatients undergoing THA were identified from a large administrative dataset. Those who did not have and those who had UC were matched 4:1 based on patient age, sex, and the Elixhauser Comorbidity Index (ECI). Matched THA patients who did not have UC (n = 19,482) and those who had UC (n = 4,874) were identified. The matched groups were compared regarding 90-day adverse and five-year survival. Further analyses were performed based on classes of medications. ResultsControlling for patient age, sex, and ECI, UC patients were at significantly higher odds of 90-day adverse events: any (odds ratio [OR] 1.59), severe (OR 1.72), and minor (OR 1.63) (all P < 0.001). Despite this, no differences in 5-year survival were identified. Relative to those who did not have UC, there were increasing odds of any adverse event based on the potency of related medications: no corticosteroids /immunomodulators/5-aminosalicylic acid (5-ASA) (OR 1.42), corticosteroids only (OR 1.58), 5-ASA ± corticosteroids OR (1.72), and immunomodulators ± corticosteroids (OR 1.74, all P < 0.001). ConclusionsTotal hip arthroplasty patients who have UC were at higher odds for 90-day postoperative adverse events relative to those who did not have UC, and this risk was even greater for those on defined classes of medications. Total hip arthroplasty patients who have UC bear specific considerations, and surgeons must carefully consider and manage the patient’s medication regimen in the perioperative period of the THA.

The Role of Radiotherapy in Indolent Ocular Adnexal and Orbital Lymphomas.

This study evaluates the oncological outcomes and toxicities of indolent ocular adnexal and orbital lymphomas (OOLs) treated with radiotherapy (RT) ± systemic therapy. A retrospective analysis of 44 patients with indolent OOLs treated with RT was conducted. Most patients (87%) had early-stage disease. Treatment involved RT alone (34%) or RT + systemic therapy (66%). The median RT dose was 30 Gy, with a median follow-up of 45 months. Local and systemic recurrence rates were 4% and 9%, respectively. Five-year overall and disease-free survival (DFS) rates were 96.2% and 83.6%. Early-stage patients showed similar DFS rates regardless of whether they received RT alone or RT plus systemic therapy. No grade 3 RT-related toxicity occurred, but systemic therapy led to grade 3 toxicity in 17% of patients. RT is essential for treating indolent OOLs, and combination with systemic therapies does not enhance outcomes for early-stage patients.

Significant Pathologic Response Following Neoadjuvant Therapy and Curative Resection in Patients With Rectal Cancer: Surgical and Oncological Outcomes From a Retrospective Cohort Study.

This study evaluated surgical complication rates, recurrence-free survival, overall survival (OS), and stoma status of patients with rectal cancer after significant pathologic response following neoadjuvant treatment and curative resection. Pathologic complete response (pCR) and near-pCR patients constitute patients in our study. Included was a retrospective cohort study of patients with rectal cancer who were diagnosed between July 2011 and September 2022 and who underwent neoadjuvant therapy and surgical resection. Of 696 patients with rectal cancer, 149 (21.4%) cases achieved significant pathologic response. During the 64 (70.5) months of follow-up, recurrence occurred in 16.1% of patients and distant metastases account for the majority of them. Age (p = 0.014) and receiving adjuvant chemotherapy (p = 0.016) were significantly related to the occurrence of recurrence. The five-year recurrence-free survival (RFS) and OS rates were obtained at 83% and 87%, respectively. Although age and surgical technique were significant factors in univariate Cox regression analysis, none of the candidate variables were significant prognostic factors for RFS in the multiple models. The risk of surgical complications remained in these patients. The most frequent complication attributed to infection (20.8%). Despite the 24.8% presence of permanent stoma at primary surgery, more than 50% of our patients lived without stoma at the last follow-up. Our recurrence rate was about 16%, and it was related to age and adjuvant chemotherapy. These patients achieved over 80% rates of five-year RFS and OS. No significant prognostic factors were found on RFS in the multivariable model. As a matter of course, the risk of surgical complications and permanent stoma has still remained in these patients.

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.

The Impact of Clinical Features on Survival and Relapse of Patients Diagnosed With T-cell Acute Lymphoblastic Leukemia – a Multicenter Cohort Study

T-cell acute lymphoblastic leukemia (T-ALL) remains understudied compared to B-cell ALL, especially in Latin America. Different biology and response to chemotherapy have been described. This retrospective multi-site cohort study analyzed data from 152 newly diagnosed T-ALL patients aged 15 years and above, between January 2010 and June 2022. The median age was 30 years, with 53.9% of the patients presenting thymic T-ALL. Asparaginase-based regimens were used in 80.5% of patients. Five-year overall survival (OS) and event-free survival (EFS) were 44.3% and 41%, respectively. Thymic (CD1a) phenotype (HR 0.50 [0.28-0.89], P = .019) and asparaginase-based regimens (HR 0.53 [0.32-0.88], P = .014) were associated with improved OS, while older age predicted inferior OS (HR 1.02, P = .017). The 60-day cumulative incidence of thrombosis was 19.5% and induction death rate of 11.2%. The study provides real-world multicenter Brazilian data on adult T-ALL, which might represent Latin America's scenario, also highlights the benefits of pediatric-inspired regimens, especially for younger adults, key prognostic factors and that awareness is needed to manage thrombotic/death risks in the early treatment phases to improve outcomes.

Anorectal melanoma: Report of two cases

IntroductionAnorectal melanoma (AM) is a rare and aggressive type of cancer. Its symptoms often resemble those of common benign anal conditions, such as hemorrhoids, leading to frequent delays in diagnosis. Consequently, about one-third of patients have metastases at the time of their initial diagnosis. The primary treatment for AM is surgical resection, while adjuvant therapies may include immunotherapy, radiotherapy, brachytherapy, and chemotherapy. The prognosis for AM is poor, with a five-year survival rate of only 20 %. Case presentationIn this study, we report two cases of patients who experienced different anorectal symptoms for a long time before their condition worsened, prompting further investigation that revealed a diagnosis of malignant anorectal melanoma. Both patients underwent surgical resection and are currently receiving adjuvant therapy. DiscussionThis article discusses the prognosis of anorectal melanoma, the current lack of consensus on treatment protocols, and the importance of maintaining a high index of suspicion for early diagnosis. ConclusionAnorectal melanoma is a rare pathology, and its prognosis is poor due to the frequent presence of metastatic forms at the time of diagnosis. Surgery, whether through abdominoperineal amputation or wide local excision, is the treatment of choice for these tumors. The use of radiotherapy (RT) is controversial and is currently indicated either as hypofractionated therapy following local excision (EL) or as palliative treatment.

XCT as a Predictor for Survival in a Population-Based Cohort of Head and Neck Squamous Cell Carcinoma.

xCT, also known as SLC7A11 (solute carrier Family 7 Member 11), is a cystine/glutamate antiporter protein that mediates regulated cell death and antioxidant defense. The aim of this study was to investigate the effect of xCT on the outcome of patients diagnosed with new head and neck squamous cell carcinoma (HNSCC). This retrospective cohort study utilized a population-based dataset, comprising all patients (n = 1033) diagnosed with new HNSCC during 2005-2015 in a population of 697,000 people. All patients (n = 585) with a tumor tissue sample available for immunohistochemical (IHC) staining were included. The follow-up rates were 97% and 81% at 3 and 5 years, respectively. Also, the specificity of the anti-xCT antibody was validated. The expression level and prognostic significance of xCT were strongly dependent on tumor location. In oropharyngeal squamous cell carcinoma (OPSCC) patients, xCT expression was a significant prognostic factor for 5-year overall survival (OAS) (HR: 2.71; 95% CI 1.67-4.39; p < 0.001), disease-specific survival (DSS) (HR: 2.58; 95% CI 1.47-4.54; p = 0.001), and disease-free survival (DFS) (HR: 2.69; 95% CI 1.55-4.64; p < 0.001). Five-year survival rates for OPSCC patients with high and low levels of xCT were OAS 34% versus 62%; DSS 51% versus 73%; DFS 43% versus 73%, respectively. According to a multivariate model adjusted for age, T-class, nodal positivity, and tobacco consumption, xCT was an independent prognostic factor for 3-year survival, in which it outperformed p16 IHC. Similar associations were not observed in squamous cell carcinomas of oral cavity or larynx. Regarding treatment modalities, xCT was most predictive in HNSCC patients who received radiotherapy. High xCT expression was associated with poor prognosis in OPSCC. Our findings suggest that joint analysis of xCT and p16 may add significant value in OPSCC treatment stratification.

Exploring resistance to immune checkpoint inhibitors and targeted therapies in melanoma.

Melanoma is the most aggressive form of skin cancer, characterized by a poor prognosis, and its incidence has risen rapidly over the past 30 years. Recent therapies, notably immunotherapy and targeted therapy, have significantly improved the outcome of patients with metastatic melanoma. Previously dismal five-year survival rates of below 5% have shifted to over 50% of patients surviving the five-year mark, marking a significant shift in the landscape of melanoma treatment and survival. Unfortunately, about 50% of patients either do not respond to therapy or experience early or late relapses following an initial response. The underlying mechanisms for primary and secondary resistance to targeted therapies or immunotherapy and relapse patterns remain not fully identified. However, several molecular pathways and genetic factors have been associated with melanoma resistance to these treatments. Understanding these mechanisms paves the way for creating novel treatments that can address resistance and ultimately enhance patient outcomes in melanoma. This review explores the mechanisms behind immunotherapy and targeted therapy resistance in melanoma patients. Additionally, it describes the treatment strategies to overcome resistance, which have improved patients' outcomes in clinical trials and practice.

Pharmaceutical Company's Choices of Indication for the First Clinical Projects in Oncological Drug Development in the United States.

We analyzed factors shaping the choice of the lead indication (i.e., cancer type) in the first clinical development projects of new oncological drugs in the United States (US), and how the type of pharmaceutical company is related to this choice. We selected 576 new clinical development projects in the US since 2000 for analysis. These projects were characterized according to three potential perspectives detected by multiple correspondence analysis: the morbidity of the cancer type which corresponds to market size of each cancer type, the company's previous experience with the cancer type, and the company's attitude to development risks. Mega firms tend to choose cancer types with higher morbidity (and large-market), previously experienced cancer types, while diverse small firms choose both major and rare cancers and both high- and low-risk projects, indicating that different sizes of firms utilize different development entry patterns. Common tendencies concerning the choice of lead indication were found across all companies. Cancer types the company had developed and launched in the past were more likely to be chosen; cancer types with high five-year survival rates and those with high competition were less likely to be chosen. The study showed that pharmaceutical companies seem to enter clinical development from cancer types where they can demonstrate their strengths and advantages through experience, depending on each cancer type's different market sizes and development difficulties. The results could provide clues for considering what support measures and incentives are appropriate to balance the efficiency of industrial development and the fulfillment of society's unmet medical needs.

Left Atrial Appendage Closure in Atrial Fibrillation Patients with Cancer.

Background: There are limited data about left atrial appendage closure (LAAC) in patients with cancer. We therefore sought to compare the outcome after LAAC in patients with vs. without cancer in a multicentre registry. Methods: In this sub-analysis of the prospective Austrian LAAC Registry, we analysed consecutive patients undergoing LAAC to assess the relationship between baseline characteristics and outcome in patients with vs. without cancer. Inverse probability weighting was performed to adjust for differences in baseline characteristics. Results: A total of 486 consecutive patients from 9 centres with a median age of 75 years (IQR 70-79 years; 35.8% female) were included. Fifty-seven patients (11.7%) had a history of cancer. The median CHA2DS2-VASc and HAS-BLED scores were similar in both groups (median [IQR], 4 [4-6] vs. 5 [3-5], p = 0.415; 4 [3-4] vs. 3 [3-4], p = 0.428 in cancer vs. other patients). Cancer patients were significantly older, and anaemia and gastrointestinal bleeding were significantly more common. Major procedural complications occurred in 5.3% vs. 7.0% (p = 0.276) of patients. The cumulative five-year survival rates were 80.7% and 84.8% in cancer vs. other patients (adjusted hazard ratio for death 1.29 [95% CI 0.67-2.48], p = 0.443). There were also no differences in one-year survival (96.1% vs. 94.0%, p = 0.582) and five-year event-free survival (64.9% vs. 74.4%, p = 0.124). Conclusions: In daily clinical practice, LAAC has already been accepted as a treatment option in patients with cancer. This retrospective analysis shows that short-term and adjusted long-term complications are similar in patients with vs. without cancer undergoing LAAC.

The Association Between Lymphovascular or Perineural Invasion in Radical Prostatectomy Specimen and Biochemical Recurrence.

The aim of this study was to test for the association between lymphovascular invasion or perineural invasion in radical prostatectomy (RP) specimens and biochemical recurrence (BCR). Relying on a tertiary-care database, we identified prostate cancer patients treated with RP between January 2014 and June 2023. Of these, the majority underwent robotic-assisted RP (81%). Kaplan-Meier survival analyses and Cox regression models addressed BCR according to either lymphovascular invasion or perineural invasion in RP specimens. Additionally, the linear trend test assessed the association between the Gleason Grade Group or pathologic tumor stage and lymphovascular or perineural invasion. Of 822 patients, 78 (9%) exhibited lymphovascular invasion and 633 (77%) exhibited perineural invasion in RP specimens. In survival analyses, the five-year BCR-free survival rates were 62% in patients with lymphovascular invasion vs. 70% in patients without lymphovascular invasion (p = 0.04) and 64% in patients with perineural invasion vs. 82% in patients without perineural invasion (p = 0.01). In univariable Cox regression models, lymphovascular invasion (hazard ratio 1.58, 95% confidence interval 1.01-2.47; p = 0.045) and perineural invasion (hazard ratio 1.77, 95% confidence interval 1.13-2.77; p = 0.013) were both associated with a higher BCR rate. After accounting for age at surgery, PSA value, pathologic tumor stage, Gleason Grade Group, lymph node invasion, positive surgical margin, surgical approach, and adjuvant radiation therapy, lymphovascular (p = 0.740) or perineural invasion (p = 0.341) were not significantly associated with a higher BCR since the Gleason Grade Group and pathologic tumor stage highly correlated with lymphovascular as well as perineural invasion. In univariable models, lymphovascular or perineural invasion is associated with BCR. After adjustment for standard pathologic tumor characteristics, lymphovascular or perineural invasion is not an independent predictor for BCR.

Platinum Resistance in Ovarian Cancer: Is This the End of the Line?

Approximately 80% of females with ovarian cancer are diagnosed with advanced disease, and around 70% of these females relapse within 3 years of first-line treatment. Five-year survival for newly diagnosed advanced ovarian cancer is less than 50%. Platinum-based chemotherapy is the cornerstone of systemic treatment; however, it is not appropriate for patients with relapsed ovarian cancer who had disease progression during previous platinum treatment, early symptomatic progression post-platinum treatment, or who are platinum intolerant. New drugs are needed to address the unmet need in patients with relapsed ovarian cancer who are not eligible for platinum-based chemotherapy. This article presents highlights from a satellite symposium conducted as part of the European Society for Medical Oncology (ESMO) Congress 2024, which took place from 13th–17th September 2024 in Barcelona, Spain. The objectives of the symposium were to improve understanding of the current treatment pathways and unmet needs for patients with ovarian cancer who are ineligible for platinum-based therapies, to raise awareness of the rationale for targeting folate receptor α (FRα) in a variety of novel therapeutics for platinum-resistant ovarian cancer (PROC), and to review the efficacy outcomes and side effects from recent clinical trials involving antibody–drug conjugates (ADC) in PROC. In this symposium, Ana Oaknin, Vall d’Hebron University Hospital, Barcelona, Spain, described the current landscape in advanced ovarian cancer and the unmet need in relapsed disease; Philipp Harter, Evangelische Kliniken Essen-Mitte, Germany, explored FRα-targeted therapeutics in PROC; and Kathleen Moore, Stephenson Cancer Center, University of Oklahoma, Norman, USA, discussed ADC development beyond FRα in PROC. The symposium concluded with a lively discussion, including questions from the audience, key examples of which are included in this article.

Metastatic Adenoid Cystic Carcinoma at the Base of the Tongue and Duplicate Breast Cancer Diagnosed During Restaging.

Adenoid cystic carcinoma (AdCC) is a rare malignant tumor that primarily affects the salivary glands but can also occur in other organs. Low incidence and unpredictable clinical behavior make AdCC one of the most difficult head and neck tumors to treat. We present the case of a 54-year-old woman with AdCC localized at the base of the tongue, following radical surgical and oncological therapy. Due to advances in palliative oncological treatment, there is a more than five-year survival period before the progression of metastatic disease. Considering the rare occurrence of this disease, a literature search was also conducted, and therapy options are discussed. Ensuring a sufficient extent of the surgical procedure is still a challenge, and most specialists agree that subsequent postoperative radiotherapy reduces the risk of local recurrence. The effective dose of radiotherapy to the area of the primary tumor and lymph nodes is not clearly defined. The distinct biological behavior of AdCC results in varying sensitivity to chemotherapy or radiotherapy compared to treatments commonly used for head and neck squamous cell carcinomas. Treatment recommendations for these rarer tumors are based mainly on case reports and small clinical trials. The acquired therapeutic experience can contribute to prolonging the survival period of patients and improving their prognosis and quality of life.

Five-year cancer survival rates in Monastir, Tunisia

Abstract Background Cancer is a major public health problem worldwide. To the best of our knowledge, there is no Tunisian population-based registry studies investigating cancer survival in Tunisia. The objectives of our study were to estimate the five-year cancer survival rates in the province of Monastir, Tunisia. Methods We performed a retrospective cohort study including patients originating from Monastir diagnosed with cancer between 2002 and 2014. Data were collected from the cancer register of the center. Patients were followed until December 2022. Results In total, 9318 cancer cases were identified of whom 5741 were included for the survival analysis. The 5-year cancer survival rate, all sites combined, was 46% (95% CI: 45-47.3). Among the 10 most frequent cancer sites in Monastir, cancers having the lowest 5-year survival rates were lung cancer in men (18.2% (95% CI: 15.6-20.7)) and stomach cancer in both sexes (32.1% (95% CI: 23.4-40.7) and 25.3% (95% CI: 16-34.5) in men and women respectively). The cancers with the highest 5-year survival rates among men were skin cancer (other than malignant melanoma) (64% (95% CI: 54.5-73.4)), prostate cancer (59.1% (95% CI:54.7-63.4)) and colon cancer (55.1% (95% CI: 47.7-62.4). In women, cervical cancer (70% (95% CI: 61.8-78.1), skin cancer (other than malignant melanoma) (66.2% (95% CI: 55.1-77.2) and breast cancer (63.8% (95% CI:58.8-67.7)) were those with the highest 5-year survival rates. Patients ≥ 65 years had the lowest 5-year survival rates for almost all cancer sites in both genders. Conclusions Our study has shown that cancer survival rates in Tunisia remain low compared to developed countries. The widespread implementation of cancer control programs including healthy lifestyle, education, screening and early detection are urgently needed. Key messages • The 5-year cancer survival rate, all sites combined, in Monastir was 46% (95% CI: 45-47.3). • Cancers with the lowest 5-year survival rates in Monastir were lung cancer in men and stomach cancer in both sexes.

Ethnic disparity in the care and management of non-ST-segment elevation myocardial infarction and its impact on short-term and long-term survival: a long-term study of a national registry

Abstract Background Previous examination of data from the United Kingdom indicates no apparent ethnic disparity in the treatment of patients hospitalised with non-ST-segment elevation myocardial infarction (NSTEMI). However, it remains uncertain whether this lack of disparity results in similar long-term survival outcomes among ethnic minority groups, particularly those with multiple underlying risk factors for coronary artery disease, when compared to White patients. Purpose To assess the impact of quality of care on short-term and long-term survival among NSTEMI patients while examining disparities based on ethnicity. Methods We analysed records of 252,964 individuals diagnosed with NSTEMI from the Myocardial Ischaemia National Audit Project database spanning 2005 to 2019, alongside Office of National Statistics data for mortality. Among them, 233,158 were identified as White patients, while 19,806 were categorised as belonging to ethnic minority groups (Asian, Black, and mixed ethnicity). Propensity score matching was used to compare average treatment effects between cohorts while survival was compared using Cox regression model. Results Ethnic minorities were younger (median age in years) (66 vs. 73, P &amp;lt; 0.001), predominantly male (70% vs. 63%, P &amp;lt; 0.001), and exhibited a higher prevalence of cardiovascular risk factors such as diabetes (52% vs. 24%, P &amp;lt; 0.001), hypertension (67% vs. 54%, P &amp;lt; 0.001), hypercholesterolemia (49% vs. 34%, P &amp;lt; 0.001), and chronic renal dysfunction (13% vs. 8%, P &amp;lt; 0.001). Ethnic minorities more frequently underwent invasive coronary angiography (80% vs. 68%, P &amp;lt; 0.001), percutaneous coronary intervention (53% vs. 44%, P &amp;lt; 0.001), and coronary artery bypass grafting (5% vs. 4%, P &amp;lt; 0.001). After conducting propensity score matching, both cohorts had no significant differences in in-hospital all-cause mortality [odds ratio (OR) 1.13, confidence interval (CI) 0.89 – 1.43; P = 0.268], cardiac mortality (OR 1.20, CI 0.89 – 1.54; P = 0.209), one-year mortality (OR 1.01, CI 0.89 – 1.13; P = 0.893) and major adverse cardiovascular events (OR 1.21, CI 0.95 – 1.48; P = 0.108). However, upon conducting a five-year survival analysis, ethnic minorities had better survival rates than their White counterparts (Hazard ratio (HR) 0.89, CI 0.86-0.92; P &amp;lt; 0.001). Conclusions Despite ethnic minorities being at a higher risk for coronary artery disease, our findings indicate that they experience better five-year survival rates than White patients. This suggests equitable access to care and potentially a more aggressive treatment approach in this relatively young patient cohort.

SAR1A Induces Cell Growth and Epithelial-Mesenchymal Transition Through the PI3K/AKT/mTOR Pathway in Head and Neck Squamous Cell Carcinoma: An In Vitro and In Vivo Study.

Head and neck squamous cell carcinoma (HNSCC) ranks sixth globally, with a 50% five-year survival rate. SAR1A exhibits high expression levels in various tumor types, yet its specific role in HNSCC remains to be clarified. In vitro assays, such as CCK8, EdU, colony formation, wound-healing, transwell, and Western blotting analyses, as well as in vivo assays, such as tumor xenografts and lung metastasis models, were conducted to evaluate the impacts of SAR1A on HNSCC proliferation, migration, and invasion. Transcriptome sequencing and KEGG enrichment pathway analysis revealed evident alterations in the PI3K/AKT/mTOR(PAM) pathways. LY294002 (a PI3K/AKT inhibitor) was used to investigate the role of the PAM pathway in proliferation, migration, and invasion in HNSCC. Univariate and multivariate Cox regression were conducted to screen SAR1A as a gene prognostic biomarker in HNSCC, and it was validated in the Cancer Genome Atlas (TCGA) database. Functional assays demonstrated that the depletion of SAR1A leads to suppressed proliferation, migration, and invasion of HNSCC cells. This is accompanied by a decrease in the expression of epithelial-mesenchymal transition (EMT)-related markers in HNSCC cell lines. In addition, the diminished capacities of proliferation, migration, and invasion observed in SAR1A knockdown cells were reversed upon the overexpression of SAR1A. Furthermore, RNA-seq and KEGG enrichment analysis demonstrated a significant alteration in the PAM pathway following SAR1A knockdown. LY294002 effectively mitigated the increased proliferation, migration, and invasion induced by SAR1A overexpression. SAR1A facilitates HNSCC proliferation and EMT via the PI3K/AKT/mTOR pathway.

Temporal trends in initiation of oral anticoagulants and stroke-free survival among elderly and very elderly patients with new onset atrial fibrillation - a 20-year perspective.

Abstract Background Oral anticoagulants (OACs) significantly reduce the risk of ischemic stroke in patients with atrial fibrillation (AF). However, evidence regarding efficacy of OACs are lacking in the very elderly patients. Aim To examine temporal trends in initiation of OACs and five-year stroke-free survival in the very elderly patients with new onset AF over a time span of 20 years. Methods From the Danish nationwide registries, we identified patients ≥ 65 years of age with new onset AF from 1999 to 2018. The index date was defined as the day of AF diagnosis for outpatients and as the day of discharge for inpatients. Patients with a prescription of OAC, history of bleeding events, or history of stroke/transient ischemic attack prior to index were excluded. Patients were divided into two age groups based on their age at index: 1) 65-84 years (elderly); and 2) ≥ 85 years (very elderly). Patients were further divided into four calendar year groups from 1999-2018, based on the year of inclusion. We investigated the initiation of OACs and calculated the absolute five-year probability of stroke-free survival in both age groups. Results We included 167,122 patients with new-onset AF between January 1st, 1999, and December 31st, 2018. Among the patients, 23.1 % were aged 85 years or older, 48 % were male and 80.5 % had a CHA2DS2-VASc score equivalent to 2 or higher for men and 3 or higher for women. Initiation of OACs increased in both age groups after the guideline implementation of DOACs in 2010 (Figure 1). In the elderly age group, the proportion of patients receiving OACs increased from 50% in 2010 to almost 90% in 2018. In the very elderly age group, the proportion increased from 25% in 2010 to almost 90% in 2018. The probability of the five-year stroke-free survival improved by approximately 15% from 1999 to 2018 in the elderly age group, with no significant changes in the very elderly age group. Conclusion The proportion of elderly AF patients receiving OAC has increased markedly in the last 20 years. Even so, stroke-free survival remains the same among the very elderly patients.Five-year stroke-free survival

Right ventricular remodelling and long-term survival after pulmonary endarterectomy versus balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension.

Pulmonary endarterectomy (PEA) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH), while balloon pulmonary angioplasty (BPA) is an alternative for inoperable patients. We aimed to compare right ventricular (RV) remodelling and late survival after PEA and BPA. In this prospective observational cohort study, we performed echocardiography at baseline and follow-up in patients with CTEPH treated with PEA (n=54) or BPA (n=44) between 2011 and 2022. Follow-up echocardiography was performed at 5 months (IQR 4-7) after PEA and 3 months (IQR 2-4) after the last BPA. Both groups showed significant improvements in left ventricular end-systolic eccentricity index, RV basal diameter and RV fractional area change (RV FAC). Tricuspid regurgitation pressure decreased by 26±18 mm Hg after PEA and 13±21 mm Hg after BPA (p=0.02 for between-group difference). Tricuspid annular systolic excursion (TAPSE) decreased by 4±5 mm after PEA but increased by 1±4 mm after BPA (p<0.001). The TAPSE/systolic pulmonary artery pressure ratio improved similarly in both groups. Five-year survival was 96% (95% CI 86% to 99%) for PEA and 79% (95% CI 61% to 89%) for BPA (p=0.25). Change in RV FAC was an independent predictor of survival (HR 0.9, 95% CI 0.82 to 0.99, p=0.03). Both PEA and BPA led to significant RV reverse remodelling, with no clear evidence of a difference in survival rates. Improvement in RV function, particularly RV FAC, was associated with better outcomes, highlighting the importance of RV recovery in CTEPH treatment.

Pituitary neuroendocrine tumors treated with stereotactic radiosurgery.

Pituitary neuroendocrine tumors (pitNETs) are benign tumors that may recur after surgical resection or persist following medical management. The objective of this study was to evaluate outcomes and toxicities of patients with pitNETs treated with stereotactic radiosurgery (SRS) at a single institution. We completed a retrospective, single-institution study of patients with pitNETs treated with frame-based, single-fraction, cobalt-60 SRS between September 2005 and June 2023. The primary endpoint was local tumor control. Secondary endpoints included endocrine control (for functional tumors), overall survival, and toxicities. A total of 88 lesions in 83 patients were treated with SRS. Most lesions (70%) were non-functional tumors. Of the 26 functioning tumors, 6 patients achieved endocrine remission with SRS alone (23%), and the remainder achieved remission with combined medical management. With a median patient follow-up of 4.7 years, no local tumor recurrences were observed with an estimated local control probability of 100%. Two- and five-year overall survival estimates were 97% (95% confidence interval [CI] 89-99) and 95% (95% CI 84-98), respectively. Causes of death were unrelated to PitNET or SRS. Twelve patients (14%) developed hypopituitarism after SRS. Despite the 34 lesions that were ≤ 3mm from optic structures, no patients developed any optic neuropathy or visual decline post SRS. SRS is a highly effective modality for recurrent or residual pitNETs. This study observed a local control of 100% with no cases of optic toxicities after a median follow-up of 4.7 years. These observed findings suggest that dose de-escalation may be possible for future treatment of pitNETs.
