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 a... Plain language summary Gastric cancer (GC) is the fourth cause of cancer-related deaths. Although different treatment algorithms, including immunotherapy, are applied in patients with unresectable ... Tweetable abstract In this retrospective study, the glucose-to-lymphocyte ratio was prognostic for metastatic gastric cancer survival. Lower glucose-to-lymphocyte ratio levels indicate longer survival.

It is well-known that inflammation plays a significant role in cancer formation and prognosis. Both lymphocyte count and red cell distribution width (RDW) has been used to predict prognosis in various cancers as an indicator of inflammation. Yet, the role of RDW-lymphocyte ratio (RLR) in determining prognosis is still unknown. We aimed to determine the prognostic role of RLR in cutaneous malignant melanoma (MM). One hundred fifteen patients with MM were included in the study retrospectively. The relationship of the clinical-pathological data with overall survival (OS) and progression-free survival (PFS) was analyzed using Kaplan–Meier curves. The cut-off values of neutrophil to lymphocyte ratio, systemic immune-inflammation index (SII), prognostic nutritional index (PNI) and RLR were determined as 2, 487, 51.5 and 6.52, respectively. OS was significantly longer in the low SII, high PNI, low RLR group, while PFS was longer in groups with high PNI and low RLR. In univariate analysis, it was determined that PFS was significantly correlated with Eastern Cooperative Oncology Group (ECOG) performance, TNM stage, PNI and RLR. Moreover, in univariate analysis, a significant correlation was determined between OS and age, ECOG performance, TNM stage, adjuvant interferon, SII, PNI and RLR. In multivariate analysis, ECOG performance, TNM stage and RLR were determined as independent prognostic factors for PFS, while TNM stage and RLR were found to be independent prognostic factors for OS. RLR could be a novel prognostic marker for both PFS and OS in patients with cutaneous MM.

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 (840–420 mg), trastuzumab (8–6mg/kg), and docetaxel (75 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.

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.
