Study Arms (1)
One arm exploratory research
EXPERIMENTALBrain radiation therapy: the dose and frequency of brain radiation therapy are determined by the doctor according to the patient's condition. Pyrrotini: 400 mg once a day, oral within 30 minutes after breakfast for 21 days. Cassitabine: twice a day, 800 mg / m2 orally within 30 minutes after each meal (one morning and one night, 12 hours apart, equivalent to a daily dose of 1600 mg / m2, one dose in the morning and one dose in the morning)
Interventions
CAPECITABINE: 800 mg/m2 twice daily, taken orally within 30 minutes after meal (one in the morning and one in the evening, 12 hours apart, equal to a daily dose of 1600 mg/m2, with one dose in the morning and one dose in the morning) .
Brain radiation therapy: the dose and frequency of brain radiation therapy are determined by the doctor according to the patient's condition.
Eligibility Criteria
You may qualify if:
- Signed written informed consent prior to enrollment.
- Age 18-75 years, female.
- Patients with pathologically confirmed HER2 expression-positive breast cancer brain metastases; HER2 expression-positive refers to those with a standard immunohistochemical staining (IHC) test showing HER2 as 3+ and/or fluorescence in situ hybridization technique (FISH) positive (confirmed by investigator review at their trial center).
- The presence of CNS lesions as confirmed by cranial CT or MRI.
- ECOG score: 0 to 2.
- Expected survival of not less than 12 weeks.
- having received no previous brain radiotherapy or having received brain radiotherapy at the dose specified in the trial protocol.
- Patients who have been on pyrrolizidine for ≤ 3 months after diagnosis of brain metastases and whose disease has not progressed.
- The function of vital organs meets the following requirements (excluding the use of any blood components and cell growth factors within 14 days).
- A) Routine blood examination criteria need to be met: Hb ≥ 100 g/L; ANC ≥ 1.5×109 /L; PLT ≥ 75×109 /L B) Biochemical examination should meet the following criteria: TBIL≤1.5×ULN (upper limit of normal); ALT and AST≤2.5×ULN; ALT and AST≤5×ULN if liver metastasis; serum creatinine≤1.5×ULN, creatinine clearance≥50ml/min (based on Cockroft and Gault formula) C) Cardiac ultrasound; left ventricular ejection fraction (LVEF) ≥ 50%
- Female patients who are non-surgically sterilized or of childbearing age are required to use a medically approved form of contraception (e.g., IUD, pill, or condom) during and for 3 months after the end of the study treatment period; female patients of childbearing age who are non-surgically sterilized must have a negative serum or urine HCG test within 7 days prior to study enrollment; and must be non-lactating.
- Subjects are voluntarily enrolled in the study, are compliant, and cooperate with safety and survival follow-up.
You may not qualify if:
- Presence of third interstitial fluid that cannot be controlled by drainage or other methods, such as massive pleural and ascites fluid.
- the presence of multiple factors that interfere with oral administration and absorption of the drug (e.g., inability to swallow, post-gastrectomy, chronic diarrhea, and intestinal obstruction).
- have a proven allergy to the drug components of this regimen.
- Patients who are known to be pregnant or planning to become pregnant, or patients of gestational age who are unwilling to use effective contraception throughout the trial period.
- Patients with the presence of meningeal metastases.
- having participated in a clinical trial of another drug within 4 weeks prior to enrollment.
- Patients who have used capecitabine during the neoadjuvant/adjuvant phase of therapy are allowed to be enrolled, but those who are ineffective or cannot tolerate capecitabine during the neoadjuvant/adjuvant phase of therapy need to be excluded; patients who have used capecitabine for ≤ 3 months after brain metastasis and whose disease has not progressed can be enrolled; other drugs for which the active ingredient is 5-fluorouracil are treated as capecitabine (Note: " used capecitabine" refers to continuous standardized use of capecitabine for ≥ 2 cycles).
- Concurrently receiving other antitumor therapy.
