RESUMEN
Objective: Hormone positive breast cancer is a tumor with high mortality. Combining antihormonal therapy with cyclin dependent kinase 4/6 inhibitors (CDK4/6i) has resulted in longer survival. The effect of inflammatory parameters such as c-reactive protein and c-reactive protein/lymphocyte ratio (CLR) on efficacy and survival in CDK4/6i treatment is unknown. In our study, we aimed to investigate the role of CLR and some parameters in predicting progression-free survival (PFS) with CDK4/6i. Methods: This retrospective cohort study included 78 patients with denovo and recurrent metastatic breast cancer treated with CDK4/6i. Cut off values for the prediction of mortality by various numerical parameter scores were performed by ROC Curve analysis. The effect of clinical variables, inflammatory and histopathological parameters on survival was analyzed by Kaplan-Meier method. Results: Neutrophil/lymphocyte ratio (NLR) and CLR were statistically significant in predicting mortality (p < 0.05). Ki67 and CLR were correlated with PFS. Age and CLR were correlated with OS (p < 0.05). CLR was statistically significant for both PFS (p = 0.022) and OS (p = 0.006). Conclusion: In patients with metastatic hormone-positive breast cancer using CDK4/6i, low CLR and low Ki67 were correlated with longer PFS duration.
RESUMEN
BACKGROUND: Cervical cancer is a tumor with high morbidity and mortality. The importance of inflammatory and metabolic parameters affecting progression-free survival (PFS) and overall survival (OS) has been investigated more intensively recently. We aimed to investigate the effect of glucose/c-reactive protein (CRP) ratio [GCR], which shows these two parameters together, on PFS in cervical cancer. METHODS: We retrospectively included 90 patients with adenocarcinoma and squamous cell carcinoma of the cervix. The effects of clinical variables, inflammatory and glycemic parameters on PFS and OS were analyzed by Kaplan-Meier method. The data were compared with the healthy control group of 90 individuals using the independent t test. The effect of parameters on mortality was analyzed using ROC curves and cut off values were determined. RESULTS: Glucose, CRP, CRP/lymphocyte ratio (CLR) and GCR were statistically significant in predicting mortality (p < 0.05). Disease stage, glucose, CRP, CLR and GCR were associated with overall survival. CRP, CLR and GCR were associated with progression-free survival (p < 0.05). In multivariate analysis, GCR was prognostic for PFS (p = 0.025). GCR was statistically significant while compared with the patient and healthy control group (p < 0.001). CONCLUSION: In cervical cancer, GCR rate was found to be prognostic independent of stage. Higher GCR rate was associated with longer PFS duration.

Aim: The tumor microenvironment of NSCLC with driver mutations, such as EGFR, ALK and ROS, is less inflammatory. Materials & methods: This retrospective study included 38 patients with NSCLC driver mutations. The relationship between clinical and inflammatory markers concerning progression-free survival and overall survival was analyzed based on Kaplan-Meier curves. Results: The mean age of the patients was 59.8 ± 11.9. Progression-free survival and overall survival were significantly longer in patients under 65 years of age and with low neutrophil-lymphocyte ratio, low systemic immune-inflammation index and high lymphocyte count (p < 0.05). Conclusion: Unlike tumor biology, peripheral inflammatory parameters, such as neutrophil-lymphocyte ratio, systemic immune-inflammation index and lymphocyte count may be associated with survival in NSCLC patients with driver mutations.
Lung cancer is the most common cancer worldwide and has a high mortality rate. Overall survival expectancy in metastatic NSCLC has increased from 11 months to 18 months. The detection of targeting mutations and the introduction of targeted treatments are the factors that increase overall survival. The contribution of immunotherapy to NSCLC is indisputable. The contribution of immunotherapy is low in NSCLC with driver mutation. We found that survival was associated with peripheral parameter indicators of inflammation despite the less inflamed tumor microenvironment. For immunotherapy to be effective in NSCLC, where there are not many treatment options, investigating different immune checkpoints or escape mechanisms and treatment planning for these will further improve survival.
Peripheral inflammatory parameters may be associated with survival in driver mutation NSCLC, in contrast to a less inflammatory tumor microenvironment.
RESUMEN
INTRODUCTION: This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs). METHODS: We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey. RESULTS: The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, Pâ =â .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, Pâ =â .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (Pâ <â .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment. CONCLUSIONS AND RELEVANCE: The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

INTRODUCTION: In the adjuvant treatment of low-risk stage III colon cancer treated surgically, 3 months of CAPOX followed by 3 months of capecitabine is not a common clinical practice. Since there are no data on this practice in the literature, we have no idea how often it is used. However, it should be noted that this application is used in some centers due to the cumulative neurotoxicity of oxaliplatin but there are insufficient data in the literature on its efficacy. METHODS: The data of patients with colon cancer treated surgically who were followed up in 12 different oncology centers in Turkey between November 2004 and June 2022 were analyzed retrospectively. RESULTS: The study included 194 patients. The treatment arms were as follows: 3 months of CAPOX followed by 3 months of capecitabine = arm A and CAPOX/FOLFOX (6 months) = arm B. There were 78 patients (40.2%) in arm A and 116 patients (59.8%) in arm B. The median age and sex distribution were similar between the treatment arms. The median follow-up period of all patients was 34.4 months (95% confidence interval, 29.1-39.7). When arm A was compared with arm B, 3-year disease-free survival (DFS) was 75.3% versus 88.4% and 5-year DFS was 75.3% versus 82.8%, respectively. There were similar DFS outcomes between the treatment arms (p = 0.09). Rates of any grade of neuropathy were numerically lower in arm A, but the difference between the treatment arms was not statistically significant (51.3% vs. 56.9%; p = 0.44). The frequency of neutropenia was similar between the treatment arms. CONCLUSION: In this study, the efficacy and safety of the 3 months of CAPOX followed by 3 months of capecitabine chemotherapy regimen in the adjuvant treatment of low-risk stage III colon cancer treated surgically were proven. This result may also support the discontinuation of oxaliplatin at 3 months while continuing fluoropyrimidines, which is a common clinical practice but lacks sufficient data.
RESUMEN
Aim: To demonstrate the prognostic importance of glucose-to-lymphocyte ratio (GLR) in metastatic gastric cancer (mGC). Methods: Retrospectively, 159 mGC patients were enrolled. Kaplan-Meier curve and Cox regression analysis were used to determine the prognostic value of the systemic immune inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI) and GLR. Results: Progression-free survival (PFS) and overall survival (OS) were associated with NLR, PNI, SII and GLR by univariate analysis. Moreover, OS was associated with Eastern Cooperative Oncology Group performance status and the chemotherapy regimen. In multivariate analysis, only GLR was found to be independently prognostic for both PFS and OS. Conclusion: In mGC, GLR may be a new prognostic marker for both OS and PFS.
Gastric cancer (GC) is the fourth cause of cancer-related deaths. Although different treatment algorithms, including immunotherapy, are applied in patients with unresectable or disseminated (metastatic) GC (mGC), survival results are not yet at the desired level. Different markers are being investigated to measure the response of cancer to treatment in these patients. Many studies have been conducted in this direction with the thought that the prognosis of these cancers will be affected by the patient's own immune response and nutritional status. Despite this, standard markers have not been established to predict cancer-related survival. Studies have shown a relationship between GC and glucose metabolism processes. Recently, a fasting blood glucose-to-lymphocyte count ratio (GLR) marker was developed that simultaneously evaluates both glucose metabolism and the patient's immune response. GLR was found to be effective in predicting survival time in cancers such as gallbladder cancer and hepatocellular carcinoma. However, the effect of GLR on survival in mGC is unclear. In this study, the authors investigated the prognostic significance of GLR in mGC. They found that low GLR was associated with longer survival in mGC. GLR may be a prognostic marker for survival in patients with mGC.

INTRODUCTION: Granulocyte colony-stimulating factors (G-CSF) are utilized both in the treatment and prophylaxis of chemotherapy-induced neutropenia. Lipegfilgrastim is a long-acting G-CSF. Albeit it provides ease of administration compared to short-acting GCSFs, some lipegfilgrastim-related adverse events may occur. Bone pain, widespread body pain, and feeling of fever are among common adverse effects, while rare but more serious adverse effects such as leukocytosis, spleen rupture, interstitial pneumonia, acute respiratory distress syndrome, capillary leak syndrome, hypokalemia, and glomerulonephritis may occur as well. CASE REPORT: We reported a case of hyperleukocytosis that developed due to prophylactic administration of lipegfilgrastim following the first course of neoadjuvant pertuzumab (840-420â mg), trastuzumab (8-6mg/kg), and docetaxel (75â mg/m2) in a 45-year-old female patient with a diagnosis of breast invasive ductal carcinoma. The patient, who presented with weakness, loss of appetite, and oral intake disorder, had elevated white blood cell (WBC), lactate dehydrogenase (LDH), and uric acid levels in her test results. Peripheral smear (PS) had a left shift. MANAGEMENT AND OUTCOME: Intravenous 0.9% NaCl and peroral allopurinol were started to be administered to the patient. On the ninth day of hospitalization, the patient's clinical manifestation improved, and her WBC, LDH, uric acid, and PS returned to normal. Besides, the progression to tumor lysis syndrome (TLS) was prevented by appropriate hydration and allopurinol treatment. In subsequent chemotherapies (CTs), lipegfilgrastim was discontinued and filgrastim was started. The patient whose hyperleukocytosis did not recur was operated on following neoadjuvant CT. The patient's routine follow-up continues without any problems. DISCUSSION: Although lipegfilgrastim-induced hyperleukocytosis has not been reported in the literature, it should be borne in mind that hyperleukocytosis and related complications may occur, as in our case.
