Clinical features and outcome of patients with primary central nervous system lymphoma admitted to the intensive care unit: a French national expert center experience.

ABSTRACT:

Introduction

To describe the reasons for intensive care unit (ICU) admission and to evaluate the outcomes and prognostic factors of patients with primary central nervous system lymphoma (PCNSL) admitted to the ICU.

Patients and methods

Retrospective observational cohort study of 101 PCNSL patients admitted to 3 ICUs over a two-decade period.

Results

Acute respiratory failure, mainly secondary to aspiration pneumonia and Pneumocystis jirovecii pneumonia, was the leading reason for ICU admission (33%). Aspiration pneumonia was more common in patients with brainstem tumor (67% vs. 0%, p?DiscussionSix-month survival of PCNSL patients admitted to the ICU appears to be relatively favorable (around 50%) and the presence of PCNSL alone is not a relevant criterion for ICU refusal. Predictive factors of mortality may help clinicians to make optimal triage decisions.

Project description:BackgroundThe Warburg effect, characterized by elevated lactate levels without tissue hypoxia or shock, has been described in patients with aggressive lymphoproliferative malignancies. However, the clinical characteristics and long-term outcomes in this population remain poorly understood.MethodsWe retrospectively analyzed 135 patients with aggressive lymphoproliferative malignancies admitted to the ICU between January 2017 and December 2022. Patients were classified into three groups: Clinical Warburg Effect (CWE), No Warburg with High Lactate level (NW-HL), and No Warburg with Normal Lactate level (NW-NL). Clinical characteristics and outcomes were compared between the groups and factors associated with 1-year mortality and CWE were identified using multivariable analyses.ResultsOf the 135 patients, 46 (34%) had a CWE. This group had a higher proportion of Burkitt and T cell lymphomas, greater tumor burden, and more frequent bone and cerebral involvement than the other groups. At 1 year, 72 patients (53%) died, with significantly higher mortality in the CWE and NW-HL groups (70% each) than in the NW-NL group (38%). Factors independently associated with 1-year mortality were age [HR = 1.02 CI 95% (1.00-1.04)], total SOFA score at admission [HR = 1.19 CI 95% (1.12-1.25)], and CWE [HR = 3.87 CI 95% (2.13-7.02)]. The main factors associated with the CWE were tumor lysis syndrome [OR = 2.84 CI 95% (1.14-7.42)], bone involvement of the underlying malignancy [OR = 3.58 CI 95% (1.02-12.91)], the total SOFA score at admission [OR = 0.81 CI 95% (0.69-0.91)] and hypoglycemia at admission [OR = 14.90 CI 95% (5.42-47.18)].ConclusionCWE is associated with a higher tumor burden and increased 1-year mortality compared to patients without this condition. Our findings underscore the importance of recognizing patients with CWE as a high-risk cohort, as their outcomes closely resemble those of individuals with lymphoma and shock, despite not requiring advanced organ support. Clinicians should recognize the urgency of managing these patients and consider early intervention to improve their prognosis.

Project description:ObjectiveTo describe the current prescribing practices of direct oral anticoagulants (DOACs) in intensive care unit (ICU) patients and the associated clinical outcomes, including the incidence of major bleeding episodes and the need for intervention (endoscopic, surgical, or interventional radiology guided).DesignObservational, retrospective chart review.Setting and participantsSingle large academic center study. Participants included patients with critical illness who were admitted to the intensive care units (ICU) at Mayo Clinic from January 1st, 2012, until May 4th, 2018. Adult ICU patients with a DOAC (apixaban, rivaroxaban, dabigatran, or edoxaban) listed as one of the active medications at the time of hospital admission were included.Results37 249 patients in medical and surgical intensive care units were screened for the study period. After excluding patients who did not qualify, 558 unique encounters were included. The median age was 69 (IQR 59-78) years; most patients were male, white Caucasians, and had a median SOFA score of 4. After excluding the patients who had major bleeding episodes in the first 24 hours, 188 (39%) were continued on the same DOAC therapy, 204 (42%) were discontinued without transitioning to another agent, and 95 (20%) were transitioned to another agent. Finally, 410 (84%) were dismissed on DOAC therapy at the end of hospitalization. The difference in the continuation rate of the same DOAC agent beyond 24 hours, discontinuation without transition to an alternate agent, or discontinuation of DOAC with a transition to an alternate anticoagulation agent was not statistically significant (P = .60). A total of 52 major bleeding events were identified. Gastrointestinal bleeding was the most common bleeding complication [n (%): 34 (65)], followed by intra-abdominal and peri-procedural bleeding [7 (13.5) and 7 (13.5)]. Thirty-three (65%) patients had a major bleeding complication requiring intervention.ConclusionsOur single-center retrospective study describes the current prescribing practices and preliminary outcomes in ICU patients with prehospital use of DOACs. Up to 20% of the patients were transitioned to a different agent within 24 hours of ICU admission, whereas a significant proportion of patients (42%) had anticoagulation discontinued altogether. Most patients who suffered a major bleeding episode required either endoscopic or surgical intervention to control bleeding.

Project description:The Radiation Therapy Oncology Group (RTOG) 9310 protocol clinical trial established high-dose methotrexate (HDMTX) as the standard for primary central nervous system lymphoma (PCNSL). We aimed to investigate the RTOG 9310 protocol's PCNSL outcomes by examining progression-free survival (PFS) and overall survival (OS) rates and determining the influential factors. Between 2007 and 2020, 87 patients were histopathologically diagnosed with PCNSL and treated with the RTOG 9310 protocol. All received HDMTX 2.5 g/m2 and vincristine 1.4 mg/m2/day for 1 day during weeks 1, 3, 5, 7, and 9, and procarbazine 100 mg/m2/day for 1 day during weeks 1, 5, and 9. Dexamethasone was administered on a standard tapering schedule from the first week to the sixth week. Whole brain radiotherapy (WBRT), consisting of 45 Gy for patients with less than a complete response to the chemotherapy or 36 Gy for complete responders, was started 1 week after the last dose of chemotherapy was administered. Within three weeks of the completion of WBRT, patients received two courses of cytarabine, which were separated by 3-4 weeks. Clinical, radiological, and histopathological characteristics were retrospectively reviewed. All patients completed five HDMTX cycles and a mean follow-up of 60.2 (range, 6-150) months. Twenty-eight (32.2%) patients experienced recurrence during follow-up. The mean time to recurrence was 21.8 months, while the mean PFS was 104.3 (95% confidence interval (CI), 90.6-118.0) months. Eleven (12.6%) patients died; the mean OS was 132.1 (95% CI, 122.2-141.9) months. The 3- and 5-year survival rates were 92.0% and 87.4%, respectively. One patient experienced acute renal failure, while the remainder tolerated any cytotoxic side effects. On multivariate analysis, the Eastern Cooperative Oncology Group performance score ≤ 2; the International Extranodal Lymphoma Study Group low-risk status; XBP-1, p53, and c-Myc negativity; homogenous enhancement; gross total resection, independently correlated with long PFS and OS. The RTOG 9310 protocol is effective for PCNSL and features good outcomes.
