PIGMENT EPITHELIAL DETACHMENT THICKNESS AND VARIABILITY AFFECTS VISUAL OUTCOMES IN PATIENTS WITH NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To evaluate the impact of pigment epithelial detachment (PED) thickness (i.e., height) and thickness variability on best-corrected visual acuity outcomes in patients with neovascular age-related macular degeneration in the Phase 3 HAWK and HARRIER trials. METHODS: Optical coherence tomography images from the pooled brolucizumab 6 mg and aflibercept 2 mg arms were analyzed for the maximum PED thickness across the macula at baseline through to week 96. Best-corrected visual acuity outcomes were compared in patients with different PED thickness and variability cut-off thresholds. RESULTS: Greater PED thickness at baseline or at week 12 was associated with lower mean best-corrected visual acuity gain from baseline to week 96 (baseline PED ≥200 µ m: +4.6 letters; <200 µ m: +7.0 letters; week 12 PED ≥100 µ m: +5.6 letters; <100 µ m: +6.6 letters). Eyes with the largest PED thickness variability from week 12 through week 96 gained fewer letters from baseline at week 96 (≥33 µ m: +3.3 letters; <9 µ m: +6.2 letters). Furthermore, increased PED thickness at week 48 was associated with higher prevalence of intraretinal and subretinal fluid. CONCLUSION: In this treatment-agnostic analysis, greater PED thickness and PED thickness variability were associated with poorer visual outcomes in patients with neovascular age-related macular degeneration and greater neovascular activity.

Thrombopoietin receptor agonists for refractory thrombocytopenia in patients after autologous hematopoietic stem cell transplantation.

OBJECTIVE: Autologous hematopoietic stem cell (ASC) transplantation (ASCT) is an effective treatment method for patients with hematological disorders and malignant diseases. The patient's ASCs are harvested prior to radiotherapy/chemotherapy, cryopreserved and then transfused back after the high-dose radiotherapy/chemotherapy conditioning treatment. Since some patients develop thrombocytopenia after receiving ASCT, it is difficult for them to bear simultaneously the management of their original disease and thrombocytopenia. The present study aimed to evaluate the efficacy and safety of thrombocytopenia therapy with thrombopoietin receptor agonists (TPORAs) after ASCT. METHODS: We retrospectively analyzed the clinical safety and efficacy of TPORA treatment for the enrolled 20 patients who developed thrombocytopenia after ASCT. The measured parameters were prolonged isolated thrombocytopenia (PIT), secondary failure of platelet recovery (SFPR) and other calculated response index. Patients with platelet count (PC) ≤ 50×109/L were treated with TPORA, namely with either eltrombopag (Elt), hetrombopag (Het), or avatrobopag (Ava). RESULTS: The group of 20 patients, who received TPORA administration for their thrombocytopenia after ASCT, had a median age of 50 years (ranging between 17 and 60 years). The median administration time of TPORA application was 48 days (ranging from 7 to 451 days); an overall response rate (ORR) was 85% with no response in 15% of patients, while with complete response (CR) in 70% of patients and partial response (PR) in 15% of patients. The median platelet count was 19 × 109/L before TPORA treatment and increased to 87×109)/L after the treatment. The TPORA treatment was safe as only 4 patients (20%) displayed a mild transaminase elevation. No other reported side effects occurred, such as thrombosis, joint pain, diarrhea, and myelofibrosis. It was demonstrated that the short response time to TPORA treatment correlated to the fast platelet recovery, when the number of megakaryocytes in the bone marrow smear exceeded 35/4.5 cm2 under a low magnification of 100 times (p = 0.015). CONCLUSION: TPORA therapy for thrombocytopenia occurring after the radiotherapy/ chemotherapy-conditioned ASCT was well tolerated and effective for platelets recovery.

Clinical Characteristics of Elderly Patients with Diffuse Large B-cell Lymphoma and the Risk Factors Affecting Cardiotoxicity of Anthracycline.

Objective: The objective of this study was to describe the clinical characteristics of elderly patients diagnosed with diffuse large B-cell lymphoma (DLBCL) and to identify the risk factors associated with anthracycline-related cardiotoxicity in this patient population. Methods: A retrospective analysis was conducted on a cohort of 170 elderly patients (≥65 years old) with DLBCL who were treated at our hospital between January 2015 and December 2020. Clinical characteristics and laboratory parameters were collected and analyzed. All patients were followed up until June 2021 to record survival, short-term efficacy, recurrence, and anthracycline-related cardiotoxicity in those who received chemotherapy. Results: Among the 170 elderly patients with DLBCL, the median progression-free survival (PFS) and median overall survival (OS) were 47 and 91 months, respectively. The 3-year PFS and OS rates were 54.1% and 70.1%, while the 5-year PFS and OS rates were 47.7% and 64.1%, respectively. The objective remission rate (ORR) was 78.83%, with a complete remission rate of 44.12% and a partial remission rate of 34.71%. Out of 143 patients who received anthracycline treatment, 46 patients experienced cardiotoxicity. Multivariate logistic regression analysis indicated that non-liposomal anthracycline use, no use of dextrexacin, and diabetes mellitus with complications were significant risk factors affecting cardiotoxicity (P < .05). Conclusions: The study showed that elderly patients with DLBCL had a high incidence of cardiotoxicity when treated with anthracycline. The results emphasize the importance of considering clinical characteristics and auxiliary examinations to prevent cardiotoxicity associated with anthracycline use.

Benefits of Dynamic Nomogram Models for Elderly Diffuse Large B-Cell Lymphoma Patients' Early Death Prediction and Clinical Application.

Background: Diffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy, and about 60% of the patients are diagnosed in their elderly age (≥65 years old). However, little is known about the early mortality and risk factors related to elderly patients with DLBCL. Methodology. From 2000 to 2019, elderly patients diagnosed with DLBCL in the Surveillance, Epidemiology, and End Result (SEER) database were involved in this research and served as test cohort. Moreover, elderly DLBCL patients from Peking University Third Hospital were used for external validation cohort. Risk factors were identified by univariate and multivariate logistic regression analyses. Nomogram models were constructed based on significance risk factors to predict the overall and cancer-specific early death. Besides that, the predictive value of the models was validated by receiver operating characteristic (ROC) analysis. Calibration plots were used to evaluate the calibrating ability. Clinical benefits of nomogram were evaluated by decision curve analysis (DCA). Results: 15242 elderly DLBCL patients obtained from the SEER database and 152 patients from Peking University Third Hospital were enrolled in this research. In the SEER database, 36.6% (5584/15242) of the patients had early death and 30.7% (4680/15242) of them were cancer-specific early death. Marital status, Ann Arbor stage, surgical treatment, radiotherapy, and chemotherapy were significant risk factors for overall and cancer-specific early death of elderly DLBCL patients. Nomograms were constructed according to these risk factors. Then, ROC analysis showed that the AUC of OS was 0.764 (0.756~0.772), and CSS was 0.742 (0.733~0.751). In the validation group, the AUC of OS was 0.767 (0.689~0.846) and CSS was 0.742 (0.743~0.83). Conclusion: The calibration plots and DCA analysis revealed that the nomograms were good at early death prediction and clinical application. Predictive dynamic nomogram models for elderly DLBCL patients were established and validated, which might play an essential role in helping physicians enact better treatment strategies.

IMPACT OF RETINAL FLUID-FREE MONTHS ON OUTCOMES IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION: A Treatment Agnostic Analysis of the HAWK and HARRIER Studies.

PURPOSE: To assess the effect of the total number of fluid-free months after loading on visual and anatomical outcomes in neovascular age-related macular degeneration patients receiving anti-vascular endothelial growth factor therapy. METHODS: This post hoc analysis pooled patient-level data from the brolucizumab 6 mg (n = 718) and aflibercept 2 mg (n = 715) arms of the HAWK and HARRIER randomized clinical trials. Based on data from Weeks 12 to 96, patients were assigned to one of five categories based on fluid-free visits (FFVs; the total number of monthly visits at which they were observed to be without retinal fluid). Three definitions of "fluid-free" were explored based on the location of the fluid observed. RESULTS: Patients allocated to Categories 4 (15-21 FFV) and 5 (22 FFV, always dry) consistently had the best visual and anatomical outcomes at Week 96, whereas patients allocated to Categories 1 (0 FFV, never dry) and 2 (1-7 FFV) consistently had the worst visual and anatomical outcomes. Variability in retinal thickness over time was lowest in Categories 4 and 5. CONCLUSION: Absence of retinal fluid at more visits after loading has a positive association with visual and anatomic outcomes in neovascular age-related macular degeneration patients, regardless of fluid type.
