Spine Stereotactic Body Radiation Therapy in Geriatric Patients: Implications of Age and Dose on Iatrogenic Vertebral Compression Fracture Risk.

Purpose: Stereotactic body radiation therapy (SBRT) is an effective treatment for spinal metastases; however, outcomes specific to a geriatric population have not been described. This study aims to investigate the efficacy and safety of spine SBRT, in particular the rate of iatrogenic vertebral compression fracture (VCF), in patients aged 70 and older.

Patients And Methods: From a prospectively maintained single-institutional database of 976 patients and 2407 spinal segments treated with SBRT for vertebral metastases between 2008 and 2021, all patients aged 70 or above were retrospectively reviewed.

Long-term Relapse and Survival in Clinical Stage I Testicular Teratoma.

Background And Objective: Studies in metastatic nonseminomatous germ-cell tumor (NSGCT) suggest that the presence of teratomatous elements in the primary tumor is a risk factor for poor survival. Many guidelines have extrapolated this observation and recommend adjuvant retroperitoneal lymph-node dissection (RPLND) even for clinical stage I (CSI) teratoma confined to the testicle. Our objective was to assess relapse-free survival (RFS), cancer-specific survival (CSS), overall survival (OS) among patients with CSI pure teratoma in comparison to CSI NSGCT.

Outcome of adolescents and young adult acute myeloid leukemia patients compared with middle-aged patients: A single centre retrospective experience.

Adult acute myeloid leukemia (AML) patients under the age of 60 often receive similar intensive treatments, while outcomes between the adolescent and young adult (AYA) age group (18-39) and middle-aged adults (40-60 years) were seldom reported. We aim to study the characteristics and outcomes of AYA patients in comparison to middle-aged adults. A retrospective analysis was performed on AYA patients treated at Princess Margaret Cancer Center between 2008 and 2018.

Cognitive Symptoms Across Diverse Cancers.

Importance: Psychosocial health services for adults with cancer should include support for cognitive symptoms and symptom clusters.

Objective: To characterize the frequency and severity of cognitive symptoms and to identify demographic and clinical risk factors associated with moderate to severe cognitive symptoms among outpatient adults with cancer seeking psychosocial support.

Design, Setting, And Participants: This cross-sectional study analyzed data from routine patient-reported symptom screening during clinic appointments at the Princess Margaret Cancer Centre in Toronto, Canada, between January 1, 2013, and December 31, 2019.

A phase 2 study of a longitudinal multidimensional rehabilitation program for allogeneic blood and marrow transplantation patients.

Allogeneic blood and marrow transplantation (alloBMT) is a curative treatment for blood cancers associated with various treatment-related adverse events and morbidities for which rehabilitation programs are currently limited. A phase 2 randomized controlled trial (RCT) was conducted to assess the feasibility, acceptability, and impact of CaRE-4-alloBMT, a longitudinal, multidimensional cancer rehabilitation program for patients undergoing alloBMT. The primary outcomes included the feasibility and acceptability of the intervention and the methods.

Primary retroperitoneal lymph node dissection for metastatic non-seminomatous germ cell tumours: outcomes and adjuvant chemotherapy.

Objectives: To compare the outcomes and treatment burden of primary retroperitoneal lymph node dissection (pRPLND) alone versus pRPLND + adjuvant chemotherapy (AC) in patients with pathological stage II (PSII) non-seminomatous germ cell tumours (NSGCT).

Patients And Methods: Retrospective review of the Princess Margaret Cancer Center eTestes cancer database identified patients with PSII NSGCT after pRPLND between 1995 and 2020. The primary outcome was relapse-free survival (RFS).

Correlating the KELIM (CA125 elimination rate constant K) score and the chemo-response score as predictors of chemosensitivity in patients with advanced ovarian carcinoma.

Background: The objective of this study is to assess the correlation between the pre-operative CA125 Elimination rate constant K(KELIM) score and the intraoperative chemo-response score (CRS) in patients with advanced high grade serous ovarian cancer(HGSC) treated with neoadjuvant chemotherapy(NACT).

Methods: This is a retrospective cohort study of patients with Stage III-IV HGSC treated with NACT from March 2010 to December 2019 at Princess Margaret Cancer Center, Toronto, Canada. KELIM scores were calculated based on the tool devised by You et al.

Predictors of Tumor Dynamics Over a 6-Week Course of Concurrent Chemoradiotherapy for Glioblastoma and the Effect on Survival.

Purpose: We present the final analyses of tumor dynamics and their prognostic significance during a 6-week course of concurrent chemoradiotherapy for glioblastoma in the Glioblastoma Longitudinal Imaging Observational study.

Methods And Materials: This is a prospective serial magnetic resonance imaging study in 129 patients with glioblastoma who had magnetic resonance imaging obtained at radiation therapy (RT) planning (F0), fraction 10 (F10), fraction 20 (F20), and 1-month post-RT. Tumor dynamics assessed included gross tumor volume relative to F0 (V) and tumor migration distance (d).

Outcomes and adverse events in older acute lymphoblastic Leukemia patients treated with a pediatric-inspired protocol with Pegylated or native Asparaginase.

This retrospective report presents the outcomes and adverse events (AEs) observed in 73 patients aged 60 years or older diagnosed with Philadelphia Chromosome-negative Acute Lymphoblastic Leukemia (Ph-negative ALL) treated with a pediatric-inspired protocol incorporating either Pegylated (PEG-ASP) or Native Asparaginase (EC-ASP). Notably, 61% of patients experienced AEs of Grade III-IV severity. The most prevalent AEs included thrombosis (35.

Stereotactic Body Radiation Therapy for Sacral Metastases: Deviation From Recommended Target Volume Delineation Increases the Risk of Local Failure.

Purpose: Although spine stereotactic body radiation therapy (SBRT) is considered a standard of care in the mobile spine, mature evidence reporting outcomes specific to sacral metastases is lacking. Furthermore, there is a need to validate the existing sacral SBRT international consensus contouring guidelines to define the optimal contouring approach. We report mature rates of local failure (LF), adverse events, and the effect of contouring deviations in the largest experience to date specific to sacrum SBRT.

Magnetic Resonance Imaging Frequency After Stereotactic Body Radiation Therapy for Spine Metastases.

Purpose: Stereotactic body radiation therapy (SBRT) is increasingly being used to treat spine metastases. Current post-SBRT imaging surveillance strategies in this patient population may benefit from a more data-driven and personalized approach. The objective of this study was to develop risk-stratified post-SBRT magnetic resonance imaging (MRI) surveillance strategies using quantitative methods.

Dual T cell depletion for graft versus host disease prevention in peripheral blood haploidentical hematopoietic cell transplantation for adults with hematological malignancies.

The ideal immunosuppressive agents to complement post-transplant cyclophosphamide (PTCy) in PBSC-based haploidentical hematopoietic cell transplantation (haplo-HCT) remain debated. This study looks at our experience with ATG-PTCy-Cyclosporine (CsA) prophylaxis in PB haplo-HCT since 2015. Between October 2015 and December 2021, 157 adults underwent haploidentical hematopoietic cell transplantation (haplo-HCT) using a GVHD prophylaxis regimen comprising rabbit-ATG, PTCy, and CsA.

Different Immunologic Profiles Are Associated With Distinct Clinical Phenotypes in Longitudinally Observed Patients With Systemic Lupus Erythematosus.

Objective: The aim of this study was to determine the immunologic profile associated with disease flares in patients with systemic lupus erythematosus (SLE) and to investigate the clinical significance of any differences observed between patients during and following a flare.

Methods: Multiparameter flow cytometry was used to examine 47 immune populations within the peripheral blood of 16 healthy controls, 25 patients with clinically quiescent SLE, and 46 patients with SLE experiencing a flare at baseline and at 6- and 12-month follow-up visits. Unsupervised clustering was used to identify patients with similar immune profiles and to track changes over time.

Dose-Escalated Radiation Therapy Is Associated With Improved Outcomes for High-Grade Meningioma.

Methods And Materials: Consecutive patients with histopathologic grade 2 or 3 meningioma treated with RT were reviewed.

Incidence and predictors of demyelinating disease in spondyloarthritis: data from a longitudinal cohort study.

Objectives: The objectives of this study were to investigate the incidence of demyelinating disease (DD) among SpA patients and to identify risk factors that predict DD in this patient population.

Methods: Axial SpA (axSpA) and PsA patients were identified from a longitudinal cohort database. Each group was analysed according to the presence or absence of DD.

Final report of TKI discontinuation trial with dasatinib for the second attempt of treatment-free remission after failing the first attempt with imatinib: Treatment-free Remission Accomplished by Dasatinib (TRAD) study.

Multiple studies have reported a significant treatment-free remission (TFR) rate of 50%-60% in patients with chronic myeloid leukaemia (CML) who discontinue tyrosine kinase inhibitor (TKI) therapy. However, the remaining half of these patients still require re-initiation of TKI therapy for leukaemia control. It remains unclear if TKI drugs should be switched for re-therapy in patients who failed the first TFR (TFR1) attempt.

AML with CEBPA mutations: A comparison of ICC and WHO-HAEM5 criteria in patients with 20% or more blasts.

AML with CEBPA mutation and AML with in-frame bZIP CEBPA mutations define favorable-risk disease entities in the proposed 5th edition of the World Health Organization Classification (WHO-HAEM5) and the International Consensus Classification (ICC), respectively. However, the impact of these new classifications on clinical practice remains unclear. We sought to assess the differences between the ICC and WHO-HAEM5 for AML with CEBPA mutation.

HCT frailty scale for younger and older adults undergoing allogeneic hematopoietic cell transplantation.

The HCT Frailty Scale is an easy prognostic tool composed of (a) Clinical Frailty Scale; (b) Instrumental Activities of Daily Living; (c) Timed-up-and-Go test; (d) Grip Strength; (e) Self-Health Rated Questionnaire; (f) Falls tests; (g) Albumin and C-reactive protein levels. This scale was designed to classify allogeneic hematopoietic cell transplant (alloHCT) candidates into fit, pre-frail and frail groups, irrespective of age. This study evaluates the ability of this frailty classification to predict overall survival (OS) and non-relapse mortality (NRM) in adult patients of all ages, in a prospective sample of 298 patients transplanted between 2018 and 2020.

High sensitivity c-reactive protein and circulating biomarkers of endothelial dysfunction in patients with chronic myeloid leukemia receiving tyrosine kinase inhibitors.

Tyrosine kinase inhibitors (TKIs) have revolutionized the management of patients with chronic myelogenous leukemia (CML); however, they may cause cardiovascular (CV) toxicities. In this cross-sectional study, we explored whether high-sensitivity C-reactive protein (hsCRP) and novel markers of vascular dysfunction were associated with exposure to specific TKIs, in 262 CML patients. Hs-CRP level was not associated with CML disease activity or treatment with a specific TKI.
