Prophylactic Use of PEG-rhG-CSF in Medium-high Risk of FN in Chemotherapy of Breast Cancer

The Effect, Safety and Pharmacoeconomics of First or Second Level-prophylactic Use of PEG-rhG-CSF in Breast Cancer Patients With Medium-high Risk of Febrile Neutropenia During Chemotherapy

This clinical study is a multiple center, registering and real-world conditional research. The breast cancer patients planning for chemotherapy evaluated with medium-high risk of febrile neutropenia (FN) are recruited, receiving the first level prophylactic use of PEG-rhG-CSF or the second level prophylactic use of PEG-rhG-CSF in at least two cycles of chemotherapy according to real-world clinical judgement and choice by physicians in local cancer center. Comparing real conditional-FN rate, FN-caused hospitalization rate and antibiotic use rate, direct/indirect medical cost.

Study Overview

• Status: Unknown
• Conditions: Febrile Neutropenia
• Intervention / Treatment: Drug: PEGCSF first level prophylactic use; Drug: PEGCSF second level prophylactic use

Detailed Description

The breast cancer patients planning for neo-adjuvant/adjuvant chemotherapy evaluated with medium-high risk of febrile neutropenia (FN) according to NCCN and ASCO guideline are recruited, receiving the first level prophylactic use of PEG-rhG-CSF or the second level prophylactic use of PEG-rhG-CSF according to real-world clinical judgement and choice by physicians in local cancer center for at least two cycles of chemotherapy. The primary outcome is FN rate, the second outcomes are rate of 3-4 grade decrease of ANC, FN-caused hospitalization, FN-caused antibiotic use rate, rate of reduction of chemotherapy dose, delay of chemotherapy, safety and pharmacoeconomics.
