Patient description: The patient is a 41-year-old obese woman coming to the emergency room with abdominal pain and vomiting. The pain that started gradually yesterday is located in the epigastric and periumbilical regions, radiating to her back. She drinks alcohol frequently and does not smoke. She has no history of allergies and uses only multivitamins daily. Her family history is positive for hypertension (her mother). She lives with her husband and has 3 children. The abdomen is tender and soft. Her bowel sounds are normal. Her heart rate is 115/min and blood pressure 110/75 mmHg. The lab studies are remarkable for leukocytosis (19.5), urea of 8.5, high CRP (145), high amylase (1200) and Glucose level of 15. Her abdominal CT scan revealed acute edematous interstitial pancreatitis with enlarged common bile duct and intrahepatic duct confirming gall stone pancreatitis. Her pregnancy test is negative and she is not breastfeeding.

Clinical trial eligibility criteria: eligible ages (years): 18.0-999.0,  Metastatic Cancer Metastatic cancer that expresses Her-2 at greater than or equal to 2+ and assessed by immunohistochemistry (IHC) in the clinical laboratory improvement amendment (CLIA) approved test in the Laboratory of Pathology, Center for Cancer Research (CCR), National Cancer Institute (NCI), National Institutes of Health (NIH). 2. Patients must have previously received systemic standard care (or effective salvage chemotherapy regimens) for metastatic disease, if known to be effective for that disease, and have been either non-responders (progressive disease) or have recurred. Subjects with estrogen receptor-positive or progesterone receptor-positive breast cancer must have progressed on or not be a candidate for anti-estrogens or aromatase inhibitors and all breast cancer patients must have progressed on or not be a candidate for an anthracycline-containing regimen and a taxane-containing regimen. 3. Patients with breast cancer must have previously received trastuzumab. Patients will not continue to receive trastuzumab during the trial period. 4. Greater than or equal to 18 years of age. 5. Willing to sign a durable power of attorney 6. Able to understand and sign the Informed Consent Document 7. Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 or 1. 8. Life expectancy of greater than three months. 9. Patients of both genders must be willing to practice birth control from the time of enrollment on this study and for up to four months after receiving the preparative regimen. 10. Serology: 1. Seronegative for human immunodeficiency virus (HIV) antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune-competence and thus be less responsive to the experimental treatment and more susceptible to its toxicities.) 2. Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then patient must be tested for the presence of antigen by reverse transcriptase polymerase chain reaction (RT-PCR) and be hepatitis C virus ribonucleic acid (HCV RNA) negative. 3. Women of child-bearing potential must have a negative pregnancy test because of the potentially dangerous effects of the preparative chemotherapy on the fetus. 11. Hematology: 1. Absolute neutrophil count greater than 1000/mm^3 without the support of filgrastim. 2. White blood cell (WBC) (> 3000/mm^3). 3. Platelet count greater than 100,000/mm^3. 4. Hemoglobin greater than 8.0 g/dl. 12. Chemistry: 1. Serum alanine aminotransferase (ALT)/aspartate aminotransferase (AST) less or equal to 2.5 times the upper limit of normal. 2. Serum creatinine less than or equal to 1.6 mg/dl. 3. Total bilirubin less than or equal to 1.5 mg/dl, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dl. 13. Left ventricular ejection fraction (LVEF) greater than or equal to 50%. 14. More than four weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen, and patients' toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo). 15. Patients who have previously received anti-cytotoxic T-lymphocyte antigen 4 (CTLA4) antibody therapy must have a normal colonoscopy with normal colonic biopsies  Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the preparative chemotherapy on the fetus or infant. 2. Active systemic infections; coagulation disorders or other major medical illnesses of the cardiovascular, respiratory or immune system; myocardial infarction; cardiac arrhythmias; obstructive or restrictive pulmonary disease. 3. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease). 4. Concurrent opportunistic infections (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities). 5. Concurrent Systemic steroid therapy 6. History of severe immediate hypersensitivity reaction to any of the agents used in this study. 7. History of coronary revascularization or ischemic symptoms 8. Documented forced expiratory volume in 1 second (FEV1) less than or equal to 60% predicted tested in patients with: 1. A prolonged history of cigarette smoking (20 pack/year of smoking within the past 2 years). 2. Symptoms of respiratory dysfunction
