Background and Objectives: To evaluate the prognostic value of the Clinical–Pathologic Stage–Estrogen receptor status and Grade (CPS+EG) staging system, which combines clinical staging, pathological staging, oestrogen receptor (ER) status, and tumour grade in predicting survival outcomes in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant therapy (NACT). Materials and Methods: A retrospective review was performed on 245 female breast cancer patients who received anti-HER2 therapy alongside NACT at the Medical Oncology Department of Kartal Dr Lütfi Kırdar City Hospital, University of Health Sciences, from April 2012 to June 2024. The CPS+EG score was calculated using the MD Anderson Cancer Centre neoadjuvant treatment response calculator. Patients were categorised into two groups based on their CPS+EG score < 3 and ≥3. The primary outcomes assessed were disease-free survival (DFS) and overall survival (OS). Kaplan–Meier and log-rank tests were utilised for time-to-event analysis; Cox regression was used for multivariate analysis. A significance level of ≤0.05 was considered. Results: The median age of the patient cohort was 51 years (range: 27–82 years). Among these patients, 183 (74.6%) had a CPS+EG score less than 3, while 62 (25.3%) exhibited a score of 3 or higher. The median follow-up duration was 37.6 months. The pathological complete response (pCR) rate across the entire cohort was 51.8%. Specifically, the pCR rate was 56.3% in the group with CPS+EG scores below 3, and 38.7% in those with scores of 3 or higher (p = 0.017). Patients with CPS+EG scores less than 3 demonstrated superior overall survival (OS), which reached statistical significance in univariate analysis. Multivariate analysis identified the CPS+EG score as an independent prognostic factor for both overall survival and disease-free survival (DFS), with hazard ratios of 0.048 (95% CI: 0.004–0.577, p = 0.017) and 0.35 (95% CI: 0.14–0.86, p = 0.023), respectively. Conclusions: The CPS+EG score is an independent and practical prognostic marker, particularly for overall survival, in patients with HER2-positive breast cancer who have received neoadjuvant therapy. Patients with a CPS+EG score < 3 have higher pCR rates and survival rates. When used in conjunction with pCR, it can improve risk categorisation and contribute to the individualisation of adjuvant strategies in the post-neoadjuvant period. Due to its ease of calculation and lack of additional costs, this score can be instrumental in clinical practice for identifying high-risk patients. Our findings support the integration of the CPS+EG score into routine clinical decision-making processes, although prospective validation studies are necessary.

Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. Although the STRIDE regimen (durvalumab plus tremelimumab) has demonstrated an overall survival benefit in clinical trials, real-world evidence remains limited, particularly in Turkish clinical practice. This study aimed to evaluate the effectiveness and safety of first-line STRIDE therapy in patients with unresectable HCC treated in routine clinical practice. Methods: We conducted a retrospective multicenter study including patients with unresectable HCC who received first-line durvalumab plus tremelimumab through the Turkish national Early Access Program across 18 oncology centers. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan–Meier method, and exploratory Cox regression analyses were performed to evaluate baseline prognostic factors. Results: Thirty-two patients were included. The median PFS was 7.25 months (95% CI, 3.68–22.29), and the median OS was 11.43 months (95% CI, 4.50–not reached). The underlying liver disease etiology was non-viral in 53.1% of patients, hepatitis B virus in 40.6%, and hepatitis C virus in 6.3%. Grade ≥ 3 treatment-related adverse events occurred in fewer than 10% of patients. Conclusions: In this multicenter real-world cohort, first-line durvalumab plus tremelimumab appeared to be a feasible treatment option and was generally well tolerated in patients with unresectable HCC. However, given the retrospective design, small sample size, and absence of a control group, these findings should be interpreted cautiously and require confirmation in larger prospective comparative studies.

Backround:Hepatocellular carcinoma (HCC) is the most common neoplasm to cause death. First line treatment options are still challenging for HCC. STRIDE regimen (durvalumab/tremelimumab) showed improved median overall survival (OS) rates however did not make differ significantly in median progression-free survival (PFS) rate. Method:We reviewed outcomes of patients with HCC who initiated durval-umab/tremelimumab between 2020 and 2024, across 18 institutions. OS and PFS were analyzed using the Kaplan–Meier and Cox models, adjusting for baseline characteris-tics. Results: A total of 32 patients were included in the study. Median PFS was was 7,25 months (%95 confidence interval (CI) 3,68-22,29) and the median OS was 11,43 months (%95 CI 4,5-NA). Non-viral, HBV and HCV constituted to etiology was re-spectively %53,1, %40,6 and %6,3 of patients. Grade ≥ 3 advers events were found less than %10 of populations. Conclusions: This real world retrospective study showed that STRIDE regimen was effective and safety for HCC in first line.

Background and Objectives: Positron emission tomography with 18F-FDG (PET-CT) provides a quantitative measure of tumor metabolic activity through the maximum standardized uptake value (SUVmax) of lung tumors—a measure of metabolic activity that may have prognostic value in non-small cell lung cancer (NSCLC). This study evaluated whether preoperative tumor SUVmax predicts outcomes in resected NSCLC. Materials and Methods: This single-center retrospective study included 209 consecutive patients with resected NSCLC who had preoperative FDG PET-CT. SUVmax of the primary tumor was recorded, and patients were stratified into low- and high-SUVmax groups to evaluate survival outcomes. Results: Median age was 62 years and 77% were male. Histologic subtypes were adenocarcinoma (44%), squamous carcinoma (43%), and others (13%), with stage I–III distribution of 39.7%, 33.5%, and 26.8%, respectively. SUVmax demonstrated moderate discrimination for mortality (AUC = 0.652), with an optimal cutoff of 11.14. Patients with SUVmax ≥ 11.14 had significantly worse OS and DFS. However, on multivariate analysis, SUVmax was not an independent predictor of outcomes, while extracapsular invasion (OS) and adjuvant chemotherapy (DFS) remained significant. Conclusions: In this cohort of resected NSCLC, high preoperative SUVmax (≥11.14) was associated with more advanced tumor stage and worse OS/DFS but was not an independent prognostic factor after accounting for other variables. Tumor invasiveness and use of adjuvant therapy were stronger outcome predictors. Preoperative SUVmax may help identify high-risk patients when considered alongside established clinicopathologic factors.

Objective: The role of adjuvant chemoradiotherapy (CRT) following curative gastrectomy remains controversial, especially in the context of D2 dissection. This research evaluated survival indicators through an analysis of previous observational studies and it evaluated treatment outcomes between patients who underwent CRT and those who received CT as their sole therapy. Methods: The researchers performed a non-randomized retrospective cohort study which analyzed 206 patients who underwent R0–R1 resection for gastric adenocarcinoma and received either adjuvant CRT (n = 107) or CT alone (n = 99). A Kaplan–Meier analysis together with Cox regression methods were used to evaluate survival outcomes of patients. Inverse probability of treatment weighting (IPTW) was applied to adjust for baseline differences between groups at the beginning of the study. The median follow-up was 52.0 months. Results: The baseline characteristics differed markedly between groups, with CRT patients showing higher rates of T4 tumors (34.6% vs. 22.2%), N3 disease (47.7% vs. 26.3%), vascular invasion (72.9% vs. 50.5%), and R1 resection (10.3% vs. 1.0%). Unadjusted survival favored CT alone (median DFS 81.7 vs. 103.9 months; median OS 86.2 months vs. not reached). These differences lost significance after IPTW adjustment (DFS: HR 1.18, p = 0.428; OS: HR 1.24, p = 0.336). T3–T4 stage, N2–N3 nodal status, vascular invasion, and positive margins emerged as independent prognostic factors. Subgroup analyses revealed no treatment interactions (all p > 0.05). Conclusions: The research used a retrospective study design which showed substantial differences between treatment groups at the beginning of the study. The survival results that showed better outcomes for CT alone became attenuated after the researchers applied propensity score adjustment to adjust for confounding from treatment selection. The study established that advanced T–N stage, vascular invasion, and positive margins were identified as independent prognostic factors. The research results are hypothesis-generating and require randomized controlled trials to establish the exact difference in effectiveness between different treatments.
