Amaç: Karaciğer, kolesterol sentezinde ve katabolizmasında çok önemli rol oynar. Non-alkolik yağlı karaciğer hastalığı (NAYKH), gelişmiş ülkelerde kronik karaciğer hastalığının en sık sebebidir ve sıklıkla diabetes mellitus, hipertansiyon, dislipidemi ve obezite gibi metabolik hastalıklarla komorbidite gösterir. Bu çalışmanın amacı Ailevi Hiperkolesterolemide (AH) NAYKH görülme sıklığını araştırmaktır. Gereç ve Yöntemler: 2017-2018 yılları arasında Erzurum Bölge Eğitim ve Araştırma Hastanesi Endokrinoloji Polikliniğine başvurmuş olan AH’li kişiler tek merkezli bu vaka kontrol çalışmasına alındı. AH’li toplam 30 kişi (17 Kadın 13 erkek), 39 kişiden oluşan (30 kadın, 9 erkek) kontrol grubu ile karşılaştırıldı. İki grup sayı ve cinsiyet yönünden denkti. Aile öyküsü kaydedildi. Tanı kan tetkikleri ve karaciğer ultrasonografisi ile kondu. Bulgular: İki grup arasında yaş ve cinsiyet açısından anlamlı fark görülmedi. NAYKH, kontrol grubundaki 39 kişiden 12’sinde saptanırken, AH grubunda 30 kişiden 16’sında görüldü (p = 0,058). AH ve kontrol gruplarının sırasıyla toplam kolesterol (333,27 ± 58,46) (219,23 ± 82,84) (mg / dl) (p = 0,000), LDL (249,93 ± 45,43) (127,11 ± 46,52) (mg / dl) (p = 0,000) ve CRP (3,37 ± 4,16) (1,43 ± 1,96) (mg / L) (p = 0,014) düzeyleri arasında anlamlı fark bulundu. Sonuçlar: AH ve kontrol grupları arasında NAYKH açısından anlamlı bir fark yoktur. Ultrasonografide NAYKH saptanmaması, AH’ye yaklaşımdaki ciddiyeti azaltmamalıdır.

Background: Bladder cancer has diverse clinical outcomes, even in patients receiving curative treatment. Traditional clinicopathological indicators inadequately assess individual risk. The Gustave Roussy Immune Score (GRIm-score), which combines albumin, lactate dehydrogenase (LDH), and neutrophil-to-lymphocyte ratio (NLR), is a prognostic factor for solid tumors; however, its role in bladder cancer remains unclear. Methods: In this retrospective cohort study, patients with bladder cancer confirmed through histopathology received bladder-preserving multimodal therapy or radical cystectomy between October 2010 and April 2025. Participants were grouped into low (0–1) and high (2–3) GRImS categories for analysis. The study examined cancer-specific survival (CSS) and the secondary outcomes of progression-free survival (PFS), overall survival (OS), and treatment completion. Survival analyses were performed using the Kaplan–Meier method and Cox proportional hazard regression. Results: A total of 89 patients participated in the study, with 73 (82.0%) and 16 (18.0%) having low and high GRIm-Score. During a median follow-up of 21.5 months, patients with a high GRIm-score had significantly shorter PFS, OS, and CSS than those with a low GRIm-score. The median CSS was 14.07 months for the high GRIm-score group and 27.75 months for the low GRIm-score group (p = 0.004). In multivariable Cox regression analysis, a high GRIm-score was independently associated with an increased cancer-specific mortality risk (hazard ratio [HR] 2.48, 95% confidence interval [CI], 1.31–4.67; p = 0.005). Treatment completion was lower in the high GRIm-score group (31.3% vs. 64.4%, p = 0.031). Conclusions: The GRIm-score serves as an independent prognostic indicator for cancer-specific survival in patients with bladder cancer undergoing curative treatment and is related to therapy completion.

Background: Finding dependable prognostic biomarkers for metastatic colorectal cancer (mCRC) is crucial. The albumin-to-carcinoembryonic antigen (CEA) ratio (ACR), a measure of nutritional-inflammatory status and tumor load, has emerged as a promising prognostic indicator. This study assessed ACR’s prognostic value of ACR in patients with mCRC. Methods: This retrospective study included 125 patients with mCRC followed at our institution between July 2010 and March 2022. ROC curve analysis was used to determine the optimal cutoff values for ACR, prognostic nutritional index (PNI), lymphocyte-to-monocyte ratio (LMR), and CEA. Kaplan–Meier and Cox regression analyses were used to evaluate progression-free survival (PFS) and overall survival (OS). Results: PFS and OS were 13.3 and 26.0 months, respectively. Patients with an ACR ≥ 4.24 experienced significantly longer PFS (16.8 vs. 11.0 months; p = 0.001) and OS (32.0 vs. 22.3 months; p < 0.001) compared with those with ACR < 4.24. In univariable analyses, ACR was significantly associated with both PFS and OS, whereas PNI, LMR, and CEA were associated with OS only. In multivariable Cox regression models ACR showed a significant association with both PFS (HR 0.413; 95% CI: 0.265–0.643; p < 0.001) and OS (HR 0.341; 95% CI: 0.210–0.551; p < 0.001), while maintenance therapy was significantly associated with PFS only and ECOG performance status, LMR and PNI with OS only. Conclusions: ACR appears to be a cost-effective biomarker that is associated with PFS and OS in mCRC. These findings suggest that ACR may have potential value for prognostic assessment and risk stratification in patients with mCRC.

Background: This retrospective cohort study evaluated the role of the PILE score as a prognostic biomarker for overall survival (OS) and progression-free survival (PFS) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) who were treated with neoadjuvant chemoradiotherapy (nCRT). Methods: This study included 108 patients with ESCC treated with weekly paclitaxel-carboplatin and concurrent radiotherapy at Erzurum Atatürk University Faculty of Medicine Hospital between January 2018 and April 2024. Patients were categorized into low- (PILE score 0–1) and high-risk (PILE score 2–3) groups. Kaplan–Meier analysis and Cox regression models were used to evaluate the association between the PILE score and survival outcomes. Results: The results showed that the high-risk PILE group had significantly shorter median OS (18.6 months vs. not reached; p < 0.001) and PFS (12.4 months vs. not reached; p < 0.001) than the low-risk group. Multivariate analysis showed that the PILE risk classification [hazard ratio (HR) = 2.527; 95% confidence interval (CI): 1.380–4.629; p = 0.003] and surgical resection (HR = 0.249; 95% CI: 0.090–0.683; p = 0.007) were independent prognostic factors for OS, whereas the PILE risk classification (HR = 2.932; 95% CI: 1.525–5.639; p = 0.001) and surgical resection (HR = 0.131; 95% CI: 0.044–0.394; p < 0.001) were independent prognostic factors for PFS. Conclusions: The study concludes that the PILE score is a robust prognostic tool for OS and PFS in patients with ESCC undergoing nCRT, highlighting its potential for risk stratification and personalized treatment planning.
