Charlson comorbidity index (CCI) in diffuse large B-cell lymphoma: A new approach in a multicenter study

Purpose: Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of adult lymphomas. The incidence of DLBCL increases with age and has a fairly rapid fatal course without treatment. Patients often have difficulty tolerating standard chemotherapy regimens due to their comorbidities. Charlson Comorbidity Index (CCI), which is calculated by considering 19 different comorbidities, was developed in 1987 and is widely used for mortality prediction in cancer patients. Literature data on CCI and hematological malignancies are limited. Main aim in this study is to evaluate the effectiveness of CCI and compare to the International Prognostic Index (IPI) scoring system in the DLBCL patient group. Methods: A total of 170 patients diagnosed with DLBCL between 1.1.2002- 1.12.2020 were included in the study. Statistical analyzes were performed among patients whose IPI and CCI scores were recorded by considering baseline data. Results: The median age of patients was 58 (range: 17–84). Thirty-five (20.6%) patients had stage III and 76 (44.7%) had stage IV disease. When the CCI, IPI and ECOG scores were compared with the mortality status of the patients as a reference, AUCs were resulted as 0.628 (95% CI: 0.506–0.749), 0.563 (95% CI: 0.484–0.639) and 0.672 (95% CI: 0.596–0.743), respectively. There was no significant difference between the ROC curves of CCI, IPI and ECOG scores. Patients with a CCI score of ≥ 4 had shorter OS comperad to those with a score of < 4. Conclusion: Rather than claiming that CCI is superior to IPI, ECOG or another scoring system in a single-center patient population, it should be stated that CCI is also an effective scoring system in patients diagnosed with DLBCL

Evaluation of neutrophil-lymphocyte ratio in patients with early-stage mycosis fungoides

Neutrophil-lymphocyte ratio (NLR), an indicator of inflammation, has been lately demonstrated as a prognostic factor and an indicator of disease activity in various diseases. However, the effects of NLR have not been investigated in mycosis fungoides (MF) patients yet. The aim of this study is to investigate the relationship between the NLR and treatment demand (systemic PUVA and/or chemotherapy), time to treatment, progression in stage, and time to progression in stage in MF patients. The data of 117 patients, who were followed with the diagnosis of MF at the Department of Dermatology in Istanbul Training and Research Hospital between April 2006 and January 2016, were analyzed retrospectively. The cutoff score for NLR was determined as 2 according to the median NLR level which was 1.96. At the time of diagnosis, the median age of patients was 54 years (range, 21-90) with 62 (53 %) female and 55 (47 %) male. Seventy-seven (65.8 %) patients required treatment during follow-up. Sixty-three (53.8 %) patients showed progression in disease stage. There was no significant difference in treatment demand, time to treatment, progression in stage, and time to progression in stage in patients with a NLR >= 2 and NLR< 2 (p = 0.331, 0.987, 0.065, and 0.119, respectively). It seems that there is no association between the NLR and treatment demand, time to treatment, progression in stage, and time to progression in stage in MF patients

Comparison of Splenectomy and Eltrombopag Treatment in the Second-Line Treatment of Immune Thrombocytopenic Purpura

Objective: Primary immune thrombocytopenia (ITP) is an acquired autoimmune disease characterized by isolated thrombocytopenia. While first-line treatments focus on inhibiting autoantibodies and platelet destruction, second- and third-line treatments include splenectomy and thrombopoietin receptor agonists. In this study, we aimed to compare the efficiency and toxicities of splenectomy and eltrombopag as second-line treatments in ITP. Materials and Methods: We retrospectively analyzed patients who were diagnosed with ITP and followed between 2015 and 2020. Patients who underwent splenectomy or received eltrombopag treatment as second-line or further therapy were included. For subgroup analyses, patients were further stratified according to whether they received eltrombopag in the second or third line of treatment. Results: There were 38 patients in the splenectomy group and 47 patients in the eltrombopag group. The mean age of patients in the splenectomy and eltrombopag groups was 43.2 and 50.5 years, respectively. Time to response was significantly shorter in the splenectomy arm (p=0.001). However, response rates at the 3 rd, 6 th, 12 th, and 24 th months did not exhibit a statistically significant difference between groups; nor did total duration of response and adverse events. Response rates at the 1st, 3rd, 6th, 12th, and 24th months and the total duration of response did not exhibit a statistically significant difference between eltrombopag subgroups. Eltrombopag treatment was ceased for 20 patients after a median of 54.1 months (range: 1-151). Among them, 12 patients (60%) did not experience a loss of response. Conclusion: Comparing the splenectomy and eltrombopag arms, even though time to achieve response was in favor of the splenectomy group, this advantage disappeared when overall response rates and response rate at the 2 nd year were considered. Using eltrombopag in the second or third line of therapy does not yield any difference in terms of time to achieving response

Clinicopathological significance of baseline T2-weighted signal intensity in functional pituitary adenomas

Purpose To assess baseline T2-weighted signal intensity (T2-WSI) of functional pituitary adenomas (FPA), and to investigate the relationship of baseline T2-WSI with clinical features, histopathological granulation patterns, and response to treatment in patients with acromegaly, prolactinoma and Cushing's disease (CD)
