Mean Platelet Volume (MPV) as an Early Predictor of Mortality in Intensive Care Patients With Cancer (MPV-CICU)

June 15, 2026 updated by: Eda Cennet Caferoğlu, Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital
This study aims to investigate whether Mean Platelet Volume (MPV) and other blood count parameters measured at admission can predict mortality in cancer patients admitted to the intensive care unit (ICU). Patients with cancer are highly vulnerable to complications and organ failure, making early risk assessment vital for improving treatment strategies. Researchers will retrospectively review the medical charts and electronic health records of adult patients who stayed in the anesthesia ICU for longer than 24 hours between 2020 and 2025. No new laboratory tests, interventions, or patient contact will occur. The collected data will be analyzed to determine the relationship between initial MPV levels and patient survival outcomes.

Detailed Description

This retrospective, observational, single-center study will evaluate the predictive value of initial Mean Platelet Volume (MPV) and other hemogram parameters (such as Red Cell Distribution Width [RDW] and platelet count) on intensive care and hospital mortality. The primary objective is to investigate the correlation between these routinely measured, cost-effective biomarkers and survival outcomes in oncological critical care patients. The study hypotheses are structured as follows:

  • H0: There is no significant relationship between the admission MPV value and intensive care or hospital mortality in intensive care patients with cancer.
  • H1: There is a significant relationship between the admission MPV value and intensive care or hospital mortality in intensive care patients with cancer. Data regarding demographics (age, sex), clinical diagnoses, comorbidities, length of stay, APACHE II, SOFA scores, and laboratory parameters (CRP, procalcitonin) will be extracted from hospital electronic database records. All patient data will be anonymized before statistical analysis.

Note on Study Design: This study is designed as a retrospective cohort study. Due to system registry constraints in the protocol module, the time perspective has been specified as 'Other' (Retrospective Cohort).

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

The study population consists of adult oncological patients who required critical care and were admitted to the anesthesia intensive care unit of a tertiary oncology training and research hospital between 2020 and 2025.

Description

Inclusion Criteria:

  • Adult patients aged 18 years and older.
  • Patients with a pathologically or clinically confirmed diagnosis of cancer (solid or hematological malignancies).
  • Patients who were admitted to the Anesthesia Intensive Care Unit (ICU) between 2020 and 2025.
  • Patients with an ICU length of stay longer than 24 hours.
  • Patients with complete medical records, including baseline complete blood count (CBC) and Mean Platelet Volume (MPV) measured at the time of ICU admission.

Exclusion Criteria:

  • Patients under the age of 18.
  • Patients who stayed in the intensive care unit for less than 24 hours.
  • Patients with missing or incomplete medical charts, laboratory data, or survival status records.
  • Patients who were readmitted to the ICU during the same hospital stay (only the first admission will be evaluated).
  • Patients who received massive blood or platelet transfusions immediately prior to the baseline laboratory measurement, which could artificially alter platelet parameters.

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.
Oncological ICU Patients
Adult patients (aged 18 and older) with a confirmed cancer diagnosis who were admitted to the anesthesia intensive care unit for longer than 24 hours between the years 2020 and 2025

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
Intensive Care Unit (ICU) Mortality
Time Frame: From the date of ICU admission up to ICU discharge, assessed up to 30 days.
The percentage of oncological patients who died during their stay in the anesthesia intensive care unit. This will be calculated based on the electronic health records and patient files.
From the date of ICU admission up to ICU discharge, assessed 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
Hospital Mortality
Time Frame: From the date of hospital admission up to hospital discharge, assessed up to 60 days.
The percentage of oncological patients who died during their overall hospital stay (including post-ICU ward follow-up).
From the date of hospital admission up to hospital discharge, assessed up to 60 days.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
