Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this trial is to observe the changes in white cell counts in patients with cancer during chemotherapy and to determine if changes in the white cell count in the early days during chemotherapy can be used as a predictor of severe neutropenia and its complications.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neutropenia is a low count of the type of white blood cells that fight bacterial infection. It is a common toxicity of chemotherapy given for cancer. When complicated by infection, it can necessitate urgent admission to hospital, and can be life-threatening. Recovery of neutrophils is necessary prior to delivery of further chemotherapy. The information available on the changes of neutrophils during chemotherapy is limited by the frequency of blood tests which have historically required a venous blood sample and hence are burdensome to the patient.

There are point-of-care medical devices which measure the white blood cell count from a capillary finger-prick sample, and can be used in the patient's home. The investigators aim to use such a device in this trial to; (i) observe the changes in white cell counts following chemotherapy delivery, (ii) determine if changes in the white cell count in the early days during chemotherapy can be used as a predictor of severe neutropenia and its complications.

This trial forms part of a larger project in which the investigators are exploring the role of home blood count monitoring in the management of severe neutropenia and its complications, and exploring the potential for home blood count monitoring to be used to optimise the dose intensity and density of chemotherapy.

This is a non-randomised trial in adults with solid tumours, recruiting from Leeds Teaching Hospitals NHS Trust only. Consenting participants are required to have regular finger-prick blood tests up to a maximum frequency of daily for the duration of the first cycle of chemotherapy, most commonly 3 weeks. A nurse will visit the participant at home and use the Hemocue® WBC DIFF to perform the test.

This trial is funded by a Technology Strategy Board (Innovate UK) Small Business Research Initiative grant.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High risk group

Defined as risk of severe neutropenia \>20% or risk of neutropenic infective complications \>10%, with severe neutropenia defined as absolute neutrophil count \<1.0 x10\^9/L.

The intervention is home finger-prick capillary blood count monitoring (up to daily).

Home finger-prick capillary blood count monitoring

Intervention Type DEVICE

A nurse will visit the participant's home according to the test schedule (up to a maximum frequency of 21 visits in a 21-day cycle) and perform the finger-prick capillary blood test and measure the neutrophil count using the Hemocue® WBC DIFF device.

Frequently given regimens

Defined as high number of cases of neutropenia, but risk of severe neutropenia \<5%.

The intervention is home finger-prick capillary blood count monitoring (up to daily).
