RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Studying samples of tumor tissue and blood from patients may help doctors understand how well these drugs can be carried to the brain.
PURPOSE: More definitive knowledge of the penetration of chemotherapeutic and other agents into the brain is necessary for the future rational design of drug and drug regimens that target brain metastases. This clinical trial is studying how well capecitabine, cyclophosphamide, doxorubicin, gemcitabine, lapatinib, paclitaxel, trastuzumab, or vinorelbine penetrates brain tumors.
OBJECTIVES:
OUTLINE: Patients are assigned to receive 1 of the 8 agents by the patient's treating oncologist.
Patients receive a single dose of the following study drugs immediately preceding surgery: oral capecitabine; cyclophosphamide IV over 30 minutes; doxorubicin hydrochloride IV over 15 minutes; gemcitabine hydrochloride IV over 30 minutes; oral lapatinib ditosylate*; paclitaxel IV over 3 hours; trastuzumab (Herceptin®) IV over 30-90 minutes; or vinorelbine ditartrate IV over 10-30 minutes . Patients then undergo craniotomy for resection of the brain metastases.
NOTE: *Patients receive oral lapatinib ditosylate at least 3 days prior to surgery and immediately before surgery.
All patients receiving cyclophosphamide, doxorubicin hydrochloride, gemcitabine hydrochloride, paclitaxel, or vinorelbine ditartrate also receive a single dose of pegfilgrastim subcutaneously (SC) 24-48 hours after the study drug administration OR filgrastim (G-CSF) SC once daily for 10 days, beginning 24-48 hours after the study drug administration.
Blood samples are collected periodically for pharmacological studies. Tissue samples obtained at surgical resection and blood samples are used to establish cell lines and analyzed for drug concentration by HPLC, LC-MS/MS or ELISA.
12,815 studies on the registry are indexed under Breast Neoplasms; 2,920 are open to participants now.
This study's enrollment of 10 is below the median of 184 across 2,711 observational studies indexed under Breast Neoplasms.

Patients will be recruited from a population of breast cancer patients who are to undergo clinically indicated surgical resection of one of more symptomatic brain metastasis(es) treated at the investigational centers.
DISEASE CHARACTERISTICS:
Treating oncologist must agree that the patient would derive clinical benefit from receiving ≥ 1 of the following study agents:
PATIENT CHARACTERISTICS:
PRIOR CONCURRENT THERAPY:
Capecitabine is an oral prodrug of 5 deoxy-5-fluorouridine (5DFRU) that is converted to 5-fluorouracil (5-FU). 5-FU is metabolized to 5-fluoro-2-deoxyuridine monophosphate (fDUMP) and 5-fluorouridine triphosphage (FUTP) which cause cell injury. Capecitabine is supplied in 150 mg (light peach colored) and 500 mg tablets (film coated)and will be administered pre-operatively.
Also known as: Capecitabine (Xeloda®) (NSC-712807)
Cyclophosphamide is biotransformed principally in the liver to active alkylating metabolites that cross-link tumor cell DNA. Cyclophosphamide is supplied in 100 mg, 200 mg, 500 mg and 1 gram and 2 gram vials as a white powder. The drug should be reconstituted with Sterile Water for Injection, USP, and may be diluted in either normal saline or D5W. Cyclophosphamide will be mixed in 250 mL of D5W and infused over 30 minutes prior to surgery.
Also known as: Cyclophosphamide (Cytoxan) (NCS-26271)
Doxorubicin is an anthracycline anticancer agent which mediates tumoricidal effects by intercalating into double-stranded DNA and producing structural changes that disrupt DNA and RNA synthesis. Doxorubicin is supplied in 10, 20, and 50 mg single use vials, and 150 mg multidose vials as a red-orange, lyophilized power which has a storage stability of a least two years. The dose will be given 60mg/m2 over 15 minutes of time pre-operatively.
Also known as: Doxorubicin (Adriamycin) (NSC-123127)
Gemcitabine is a fluorinated deoxynucleoside prodrug which disrupts DNA synthesis and induces apoptosis in a broad number of human tumors, including breast cancer. Gemcitabine is supplied as a lyophilized powder in sterile vials containing 200 mg of 1000 mg (1 gram) of gemcitabine as the hydrochloride salt (expressed as the free base) mannitol and sodium acetate. Dosage will be 1250mg/m2, IV pre-operatively over 30 minutes.
Also known as: Gemcitabine (Gemzar®) (NSC-613327)
: Lapatinib ditosylate monohydrate tablets, 250 mg, are oval, biconvex, orange, film-coated tablets with one side of the tablet plain and other side of the tablet embossed with FG HLS. Lapatinib may also be supplied as oval, biconvex, tan tablets, with no markings. Lapatinib will be administered for at least 3 days pre-operatively at 1250mg.
Also known as: Lapatinib (Tykerb®) GW572016
Paclitaxel will be given as an intravenous infusion (80mg/m2) the morning of surgery as specified in the protocol, diluted in 0.9% Sodium Chloride Injection, USP, or 5% Dextrose Injection. Paclitaxel will be administered via an infusion control device (pump) using non-PVC tubing and connectors, such as the IV administration sets (polyethylene or polyolefin) which are used to infuse parenteral nitroglycerin.
Also known as: Paclitaxel (Taxol®) (NSC-673089)
Vinorelbine (Navelbine®) is a unique semi-synthetic vinca alkaloid 3', 4-didehydro-4' deoxy-C'-norvincaleukoblastine (ditartrate) (IUPAC). The pyogen free, sterile parenteral dosage form is supplied in 10 mg/1 ml ampules/vials and 50 mg/5 ml vials. It will be administered at a dosage of 25mg/m2 IV over 10-30 minutes pre-operatively.
Also known as: Vinorelbine (Navelbine®) (INSC-608210)
Trastuzumab is a monoclonal immunoglobulin G1 kappa antibody which acts as a mediator of antibody-dependent cellular cytotoxicity (ADCC) agent through its high affinity, high specificity binding to extracellular domain of HER2 Receptor. Trastuzumab is supplied as a lyophilized, sterile powder containing 440 mg trastuzumab per vial under vacuum. Each carton contains one vial of 440 mg trastuzumab and one 30 ml vial of bacteriostatic water for injection, USP, 1.1% benzyl alcohol. This will be given the morning of surgery at 2mg/m2 IV over 90 minutes.
Also known as: Trastuzumab (Herceptin®) (NSC #688097)
Concentration of drug
Serum/plasma concentrations: measured for all agents except trastuzumab by HPLC or LC-MS/MS. Trastuzumab concentrations measured by enzyme linked immunosorbent assay. Compared to tissue levels and the extent of change in serum/plasma during the surgical process will be noted. Tissue Concentrations: determined by HPLC/LC-MS/MS or by ELISA. The objective would be to compare tumor concentration to brain adjacent to tumor, which often has an intact BBB. The degree of BBB compromise in the specimens will be assessed through analysis of serum protein levels and hemoglobin.
