Prognostic stratification of lymphomas employs biochemical tests; however, these tests do not offer a viable means of assessing response. We included 108 patients with lymphoma who underwent treatment at the Department of Medical Oncology, Hacettepe University, between January 2015 and December 2017. Patients were grouped into good and poor responders, and changes in biochemical parameters were assessed for their utility in evaluating patient response. We evaluated the proposed scoring system’s effect size using Cramer’s V test. Fifty-seven patients were male, 51 patients were female, and the median age of the patients was 50 years. Twenty-seven patients had HL, 72 patients had B-cell NHL, and 9 patients had T-cell NHL. Fifty-three patients had stage IV, nine patients had stage III, 23 patients had stage II, and 22 patients had stage I disease. Levels of total protein (from 7.12 to 6.79 gr/ dL, p< 0.01), ß2-microglobulin (from 2287 to 2039 ng/mL, p= 0.07), and lactate dehydrogenase (from 297.8 to 230.1 U/L, p< 0.01) decreased in patients with good response, whereas nothing significant was found in patients with poor response. After transforming the parameters, we proposed a 4-point ordinal system comprising total protein, ß2-microglobulin, and lactate dehydrogenase values. Subsequent analysis demonstrated a nearly high effect size (Cramer’s V 0.461) and significance in logistic regression (p< 0.01). Our study presents the first scoring system for response assessment in lymphoma using biochemical tests. Further research is necessary to validate our scoring system.

One of the most significant changes is that isocitrate dehydrogenase (IDH) mutant forms of glioblastoma multiforme (GBM) have been differentiated into separate entities, no longer allowing entries to be classified as not otherwise specified (NOS). As a result, this entity only comprises the most aggressive adult-type tumors and established prognostic factors no longer apply. Glioblastoma (GBM) IDH-wildtype CNS WHO grade 4 typically presents necrosis and/or microvascular proliferation and molecular alterations. Herein, we aimed to classify glioblastoma cases to establish a patient survival pattern based on age, gender, the number of masses, tumor location, functional localization, presence of shift, the volume of edema and necrosis, extent of surgery, radiotherapychemotherapy protocol, and isocitrate dehydrogenase (IDH) presence, affecting overall survival were determined retrospectively. A total of 433 patients &gt;20 years old with primary GBM were treated in a single institution between 1996 and 2019. The median survival was 9±0.62 [95% CI 7.78-10.21] months and the survival rate after diagnosis was 39.4% in 1st year, 17% in 2nd year, and 5% in 3rd year. Statistically, age, tumor location, edema, and necrosis were indicated as independent preoperative predictors of prognosis, and younger age at diagnosis, the left temporal and the right occipital location, maximal tumor resection, and administration of temozolomide adjuvant chemotherapy were revealed favorable prognostic factors.

CRNDE is a novel-defined lncRNA. We evaluated the possibility of using CRDNE circulating lncRNA as a noninvasive biomarker. Also, we examined the effect of circulating CRNDE lncRNA on the pathogenesis of CRC and its association with the KRAS, NRAS, and BRAF somatic variants commonly observed in CRC. In this study, we enrolled plasma and FFPE tissue samples of 50 advanced CRC patients and plasma samples of 31 individuals in the control group of similar ages. Then, we performed plasma extraction, total RNA isolation, cDNA synthesis, and circulating lncRNA expression analysis, respectively. Also, we carried out KRAS, NRAS, and BRAF somatic variant analysis from FFPE tissues. Our results showed that the expression level of CRNDE (p= 0.002) were significantly upregulated in the CRC when it was compared to with the control group. The calculated area under the curve of the receiver operating characteristic was 0.70. We found a statistically significant difference between the KRAS somatic variants and the circulating CRNDE lncRNA (p= 0.031). This study demonstrated that CRNDE circulating lncRNAs may be used as a potential non-invasive biomarker in CRC. In our study, it was determined that there is a significant relationship between the frequently observed KRAS somatic variants and CRNDE in advanced-stage CRC cases. To the best of our knowledge, this is the first study to show the association of CRNDE circulating lncRNA with advanced CRC.

Moreover to achieve our aim, we investigated the relationship between the patients’ HDAC protein expression rates and their prognosis. In no patients, tumors were located in the cardia and corpus. While the median HDAC1 protein score was 3.5 in the early stage patients, it was 8 in the advanced stage (stage 1-2) patients, and 12 in the metastatic stage (stage 4) patients. There was a significant correlation between HDAC protein positivity and tumor localization (p= 0.030). Significant correlation was observed between histopathological stages and median HDAC1 protein scores. (p= 0.021). The HDAC1 protein score increased as the patients’ stage progressed. Given the relationship between HDAC1 proteins and the survival of the patients, the 2-year survival rate was high in HDAC1 positive patients; however, it was not statistically significant. According to the results of our study, in HDAC1-positive gastric cancer patients, there was no significant relationship between SUVmax showing tumor metabolism in 18F-FDG PET/CT.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136369645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study investigated the relationship between bone marrow fluorodeoxy-D-glucose (FDG) uptake and survival to evaluate prognosis in limited-stage SCLC. This single-center retrospective study examined a total of 220 patients diagnosed with limited-stage SCLC between January 2010 and June 2019. Bone marrow FDG uptake, serum inflammatory markers, and other factors used to determine the prognosis, as well as overall survival (OS) and progression-free survival (PFS), were recorded and retrospectively analyzed. Within physiological limits, bone marrow standardized uptake value (SUV) mean of > 1.95 was identified as a good prognostic factor for PFS (p= 0.03). The multivariate analysis of OS and PFS revealed that the Eastern Cooperative Oncology Group (ECOG) performance scale (p= 0.001) was a common independent prognostic factor. Stages of the disease, albumin levels and bone marrow-to-liver ratio (BLR) [one of the positron emission tomography/computed tomography (PET/CT) parameters] of < 0.8 were prognostic factors for OS. The bone marrow SUV mean was positively correlated with the primary tumor SUV max and SUV mean. The bone marrow SUV mean is a parameter that can be used to predict PFS in limited-stage SCLC. For OS, in turn, the BLR was identified as an independent factor.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136369646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LA-NPC patients (n= 188) who underwent C-CRT and pre-and post-C-CRT oral examinations from August 2010 to January 2022 were included. The three-tiered SIS groups were created using the serum albumin and lymphocyte-to-monocyte ratio (LMR) measures obtained on the first day of C-CRT: SIS-0: Albumin ≥ 40 g/dL and LMR ≥ 4.44); SIS-1: Albumin < 40 g/dL and LMR < 4.44 or albumin ≥ 0 g/dL and LMR ≥ 4.44; and SIS-2: Albumin < 40 g/dL and LMR <4.44. The primary objective was to ascertain whether there were irrefutable associations between pretreatment SIS groups and the respective post-C-CRT RIT and ORNJ rates. RIT and ORNJ were diagnosed in 33 (17.6%) and 21 (11.1%) patients, respectively. There were 12 (32.4%), 13 (12.7%), and 18 (45.0%) cases diagnosed with RIT in the respective SIS-0, SIS-1, and SIS-2 groups (p< 0.001). Similarly, there were 1 (2.7%), 11 (9.9%), and 9 (22.5%) cases with ORNJ diagnoses in the corresponding SIS groups (p< 0.001). The multivariate analysis’s findings revealed that the SIS grouping was an independent predictor of RIT (p< 0.001) and ORNJ incidence rates (p< 0.001). Our study’s findings indicate that the novel pretreatment SIS grouping is a dependable biomarker-based system, which can accurately predict the rates of RIT and ORNJ in LA-NPC patients who receive definitive C-CRT.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136369647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is no generally accepted approach algorithm with a common consensus in determining the risk of malnutrition. The GLIM criteria, developed by a common consensus of major global nutrition societies (Global Leadership Initiative on Malnutrition), are one of the most frequently used approaches recently. Method A total of 50 patients with a diagnosis of leukemia (AML, ALL) were included in the study. NRS-2002 and then GLIM criteria were used to determine the nutritional status of the patients. The study parameters were evaluated by dividing the patients into two groups as malnourished and non-malnourished. Comparing the malnourished group to the non-malnourished group; while platelet, albumin, and prealbumin values and anthropometric measurements were found to be statistically significantly low, infection incidence rate, fever duration and rate, the need for multiple and longer courses of antibiotics and antifungal usage rate were found to be statistically significantly high (p< 0.005). Adequate nutritional level of the patient does not affect the neutrophil and platelet recovery time, but infection incidence rate and rate of fever within the same period of neutropenia statistically significantly reduces the need for antibiotics and antifungals. In patients with a diagnosis of leukemia who have long hospital stays, it is important to ensure adequate calorie intake with regular dietitian follow-up, to obtain a balanced calorie intake from macronutrients, and to add micronutrient support.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136369827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
