Timing of Renal Replacement Therapy Initiation in Tumor Lysis Syndrome (TENDERS)

January 8, 2026 updated by: University Hospital, Bordeaux
The TENDERS study aims to evaluate the impact of the timing of renal replacement therapy (RRT) initiation on outcomes in patients with tumor lysis syndrome (TLS) and associated acute kidney injury (AKI). The study will compare early versus delayed RRT initiation, examining the effect on renal function at 30 days post-treatment.

Detailed Description

Tumor lysis syndrome (TLS) is a common and life-threatening complication in patients with hematologic malignancies, characterized by severe metabolic imbalances due to rapid tumor cell destruction. This syndrome frequently leads to acute kidney injury (AKI), requiring renal replacement therapy (RRT) in about 50% of cases. Despite its clinical significance, there is a lack of consensus on the optimal timing of RRT initiation in TLS-related AKI. Studies in other forms of AKI suggest no difference in outcomes between early and delayed RRT initiation, but these results are not directly applicable to TLS patients. This study seeks to fill this gap by analyzing the timing and outcomes of RRT initiation in TLS patients. The retrospective study will collect data from multiple intensive care units (ICUs) across France. Procedure: The study will retrospectively analyze patient data from 2013 to 2023, comparing early vs. delayed RRT initiation. Follow-up: Data on renal function, RRT usage, and mortality will be collected 30 days and one year after ICU admission.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

This is a retrospective, multicenter cohort study conducted across several intensive care units (ICUs) in France. Data will be collected retrospectively from patient records and analyzed to assess the impact of early versus delayed RRT initiation on clinical outcomes in patients with TLS-induced AKI.

Description

Inclusion Criteria:

  • Adults aged ≥18 years.
  • Hospitalized in the ICU between January 1, 2013, and December 31, 2023.
  • Diagnosed with a hematologic malignancy or solid tumor requiring chemotherapy.
  • Diagnosed with TLS based on the presence of two or more biochemical criteria (e.g., hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia) within 3 days before or 7 days after chemotherapy initiation.

Exclusion Criteria:

  • Patient or family opposition to data collection for research purposes.
  • Incomplete medical records that preclude data extraction.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Patients with early initiation of renal replacement therapy (RRT)
Patients with early initiation of RRT, RRT within 24 hours of acute kidney injury (AKI) diagnosis.
Patients with delayed initiation of RRT
Patients with delayed initiation of RRT, RRT initiated only after urgent clinical indications arise, such as severe hyperkalemia or metabolic acidosis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Renal dysfunction at ICU discharge
Time Frame: From baseline to up to 30 days .
The primary outcome is renal dysfunction at ICU discharge, defined as a ≥25% increase in serum creatinine from baseline, assessed at the time of ICU discharge.
From baseline to up to 30 days .

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of AKI
Time Frame: At baseline
Incidence of AKI related to Tumor lysis syndrome (TLS), assessed at ICU admission.
At baseline
