Summary

Investigating the Association Between Corticosteroid Use and Improvement in Doxorubicin Liposome-Induced Cutaneous Toxicity: Exploring the Feasibility and Mechanisms of Corticosteroids in Mitigating Liposomal Doxorubicin-Related Dermatologic Adverse Effects.

Eligibility

Inclusion Criteria:

1. Patients aged 18-70 years (inclusive), regardless of gender.
2. Diagnosis \& Treatment Plan: Histopathologically confirmed early-stage or advanced breast cancer patients eligible for AC regimen (liposomal doxorubicin + cyclophosphamide) chemotherapy per clinical guidelines.
3. ECOG Performance Status: Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1.
4. Anticipated survival ≥3 months.
5. Organ Function Requirements:

   Hematologic: Absolute neutrophil count (ANC) ≥1.5 × 10⁹/L ,Platelet count ≥75 × 10⁹/L Hemoglobin ≥90 g/L

   Hepatic:

   Non-liver metastasis: Total bilirubin (TBIL) ≤1.5 × upper limit of normal (ULN) Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 × ULN Liver metastasis: TBIL ≤1.5 × ULN ,ALT and AST ≤5 × ULN

   Renal:

   Serum creatinine (Cr) ≤1.5 × ULN or creatinine clearance (Ccr) ≥50 mL/min

   Coagulation:

   International normalized ratio (INR) or prothrombin time (PT) ≤1.5 × ULN Activated partial thromboplastin time (APTT) ≤1.5 × ULN
6. Contraception:

   Female patients: Must use effective contraception (e.g., intrauterine device \[IUD\], oral contraceptives, or condoms) during the study and for 6 months after study completion. A negative serum pregnancy test within 7 days prior to enrollment is required, and patients must be non-lactating.

   Male patients: Must agree to use contraception during the study and for 6 months after study completion.
7. Informed Consent: Patients must voluntarily participate, provide signed informed consent, and comply with protocol-specified procedures (blood tests, follow-ups, etc.).

Exclusion Criteria:

1. Received chemotherapy, radiotherapy, biologics, targeted therapy, immunotherapy, or other antitumor treatments within 4 weeks before the first study dose (or within 5 half-lives, whichever is shorter). Exceptions: The washout period may be adjusted per investigator judgment (e.g., shortened to 2 weeks for endocrine therapy to avoid prolonged patient waiting).
2. Previous treatment with liposomal doxorubicin or similar formulations.
3. Allergy History: Known hypersensitivity to liposomal products or doxorubicin.
4. Cardiovascular Diseases:

   Severe arrhythmias/conduction abnormalities (e.g., clinically significant ventricular arrhythmias, second- or third-degree AV block).

   History of myocardial infarction, coronary artery bypass grafting (CABG), or heart failure (NYHA Class ≥II).

   LVEF ≤50%or prolonged QTcF (\>450 ms in males; \>470 ms in females).
5. Active Infections: Grade ≥2 （NCI CTCAE v5.0）
6. Immunosuppression:

   Active autoimmune diseases, immunodeficiency (e.g., HIV-positive), or congenital/acquired immune disorders.

   History of organ transplantation or chronic corticosteroid use.
7. HBsAg-positive with HBV-DNA ≥500 IU/mL. Exception: If HBV-DNA \<500 IU/mL and chronic hepatitis is deemed stable/inactive by the investigator, enrollment is permitted.
8. Other Infections: Positive for HCV antibody or syphilis-specific antibody.
9. Neurological/Psychiatric Disorders: History of epilepsy, dementia, or other uncontrolled conditions.
10. CNS Metastases: Symptomatic brain or leptomeningeal metastases, or uncontrolled CNS lesions. Exception: Asymptomatic brain metastases or lesions stable for ≥28 days without steroids/antitumor therapy are allowed.
11. Any other condition that, per investigator assessment, may compromise patient safety or study compliance.
12. Pregnant or breastfeeding women.
13. Patients deemed ineligible for the study by the investigator.
