RESUMO
OBJECTIVE: To evaluate the efficacy and safety of nivolumab in the second-line (2L) or later-line (LL) treatment of patients with locally advanced/metastatic non-small cell lung cancer (NSCLC) in real-life setting in Türkiye. METHODS: This study was designed as a national, multi-center, retrospective study. The study population was evaluated in two groups for the line of nivolumab therapy: those receiving nivolumab in the 2L (Group 2L) and third-line (3L) or LL (Group 3L/LL). Efficacy was evaluated based on one-year overall survival (OS) and progression-free survival (PFS). Safety was evaluated based on treatment-related adverse events (AEs) and nivolumab discontinuation rate. RESULTS: Of 244 patients, 52.9% were in Group 2L and 47.1% were in Group 3L/LL. Demographic and clinical characteristics did not differ between the groups. In Group 2L and Group 3L/LL, one-year OS and PFS rates were 60.8% and 61.4% (p = 0.592) and 31.2% and 21.3% (p = 0.078), respectively. The objective response rate (ORR) was 34.7% in Group 2L and 27.3% in Group 3L/LL (p = 0.262). The percentage of patients reporting at least one AE in Groups 2L and 3L/LL was 34.9% and 43.5%, respectively (p = 0.169). Fatigue was the most common (16.4%) treatment-related AE in each group. The groups were comparable regarding the AE frequency. Nivolumab was discontinued in 61 patients in Group 2L and 53 patients in Group 3L/LL, with the most common reason being disease progression (57.4% and 66.0%, respectively). CONCLUSION: Nivolumab is safe and effective in the 2L or 3L/LL treatment of locally advanced/metastatic NSCLC and associated with acceptable AEs in real-life setting.
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer (around 85% of all lung cancers). Patients with NSCLC are usually diagnosed at advanced or metastatic stages. When cancer cells spread to other areas from where they first formed, it is called metastatic cancer. Surgery may not be a treatment option for such patients. Currently, immunotherapeutic agents are used in the treatment of NSCLC. Nivolumab is one of the approved immunotherapeutic agents in the treatment of patients with metastatic NSCLC, who have failed after receiving chemotherapy. Our study explored the efficacy and safety of nivolumab in real-life setting in Türkiye. Nivolumab effectiveness was evaluated by overall survival (OS) and progression-free survival (PFS) rates. OS indicates the proportion of patients who are still alive at a given time after diagnosis or treatment initiation. PFS refers to "the length of time during and after cancer treatment that a person lives with the disease but does not get worse." In the present study, one-year OS for 244 patients who received nivolumab was 61.1% and one-year PFS was 26.4%. Nivolumab safety was evaluated based on the frequency of adverse events observed during nivolumab therapy. Of the patients 38.9% had at least one side effect, with fatigue being the most common (16.4%). Our results support the earlier studies and showed that nivolumab was a safe and effective agent and is associated with acceptable side effects.

To evaluate radiological and clinical features in metastatic anaplastic lymphoma kinase+ non-small cell lung cancer patients and crizotinib efficacy in different lines. This national, non-interventional, multicenter, retrospective archive screening study evaluated demographic, clinical, and radiological imaging features, and treatment approaches in patients treated between 2013-2017. Totally 367 patients (54.8% males, median age at diagnosis 54 years) were included. Of them, 45.4% were smokers, and 8.7% had a family history of lung cancer. On radiological findings, 55.9% of the tumors were located peripherally, 7.7% of the patients had cavitary lesions, and 42.9% presented with pleural effusion. Pleural effusion was higher in nonsmokers than in smokers (37.3% vs. 25.3%, Pâ =â .018). About 47.4% of cases developed distant metastases during treatment, most frequently to the brain (26.2%). Chemotherapy was the first line treatment in 55.0%. Objective response rate was 61.9% (complete response: 7.6%; partial response: 54.2%). The highest complete and partial response rates were observed in patients who received crizotinib as the 2nd line treatment. The median progression-free survival was 14 months (standard error: 1.4, 95% confidence interval: 11.2-16.8 months). Crizotinib treatment lines yielded similar progression-free survival (Pâ =â .078). The most frequent treatment-related adverse event was fatigue (14.7%). Adrenal gland metastasis was significantly higher in males and smokers, and pleural involvement and effusion were significantly higher in nonsmokers-a novel finding that has not been reported previously. The radiological and histological characteristics were consistent with the literature data, but several differences in clinical characteristics might be related to population characteristics.

INTRODUCTION: Adrenocortical carcinoma (ACC) is a rare yet highly malignant tumor associated with significant morbidity and mortality. This study aims to delineate the clinical features, survival patterns, and treatment modalities of ACC, providing insights into the disease's prognosis. MATERIALS AND METHODS: A retrospective analysis of 157 ACC patients was performed to assess treatment methodologies, demographic patterns, pathological and clinical attributes, and laboratory results. The data were extracted from the hospital's database. Survival analyses were conducted using the Kaplan-Meier method, with univariate and multivariate analyses being performed through the log-rank test and Cox regression analyses. RESULTS: The median age was 45, and 89.4% had symptoms at the time of diagnosis. The median tumor size was 12 cm. A total of 117 (79.6%) patients underwent surgery. A positive surgical border was detected in 26 (24.1%) patients. Adjuvant therapy was administered to 44.4% of patients. The median overall survival for the entire cohort was 44.3 months. Median OS was found to be 87.3 months (95% confidence interval [CI] 74.4-100.2) in stage 2, 25.8 (95% CI 6.5-45.1) months in stage 3, and 13.3 (95% CI 7.0-19.6) months in stage 4 disease. Cox regression analysis identified age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as significant factors associated with survival in patients with nonmetastatic disease. In metastatic disease, only patients who underwent surgery exhibited significantly improved overall survival in univariate analyses. CONCLUSION: ACC is an uncommon tumor with a generally poor prognosis. Understanding the defining prognostic factors in both localized and metastatic diseases is vital. This study underscores age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as key prognostic determinants for localized disease, offering critical insights into the complexities of ACC management and potential avenues for targeted therapeutic interventions.

BACKGROUND: To evaluate the relationship of overall survival (OS) and progression-free survival (PFS) with the derived neutrophil-lymphocyte ratio (dNLR), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), and platelet-lymphocyte ratio (PLR) in patients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC). METHODS: The study included 43 patients with EGFR-mutant metastatic NSCLC. The dNLR, NLR, LMR, and PLR values were calculated using the baseline complete blood counts before and after treatment with erlotinib. RESULTS: The NLR value had the best diagnostic test performance with a sensitivity of 91.3%. dNLR, NLR, LMR, and PLR were found to be significant for the prediction of OS and PFS. While the delta dNLR and NLR values were significant for OS, only the delta NLR value was significant for PFS. CONCLUSIONS: The dNLR, NLR, LMR, and PLR values were found to be significant in the prediction of OS and PFS in erlotinib-treated metastatic NSCLC. Further clinical studies are needed to determine the ideal target-specific tyrosine kinase inhibitor in cases of metastatic NSCLC presenting with the EGFR-activating mutation.
