Filter by:Patients with untreated clinical stage II breast cancer are eligible. An excisional biopsy of the primary tumor is acceptable, but without definitive local therapy or prior chemotherapy. Histologic confirmation of invasive carcinoma is required. Patients are prospectively randomized to receive five 21-day cycles of dose-intense (5-fluorouracil, adriamycin, leucovorin, cytoxan, granuloctye-colony stimulating factor [FLAC/G-CSF]) chemotherapy either before (preoperative) or after (postoperative) local therapy. Chemotherapy is given as an outpatient. For patients receiving preoperative chemotherapy, local therapy (modified radical mastectomy, or breast segmentectomy/axillary dissection/breast radiotherapy according to patient preference) is performed 3-4 weeks after last chemotherapy. For patients receiving postoperative chemotherapy, chemotherapy will begin 2-3 weeks after local therapy. Immediate reconstruction for mastectomy is acceptable. Upon completion of local therapy and chemotherapy in either treatment group, all estrogen receptor positive patients receive tamoxifen for 5 years. Follow-up consists of history and physical examination each 3 months for first 3 years, each six months for years 4 and 5, and yearly thereafter. Mammogram, bone scan, chest x-ray and blood work are performed yearly.
This study is designed to evaluate the efficacy of high dose melphalan and autologous bone marrow transplantation given as consolidation therapy to patients with inflammatory or metastatic carcinoma of the breast in complete remission. All patients entered will receive induction therapy with cyclophosphamide, adriamycin, methotrexate and 5-fluorouracil with hormonal synchronization utilizing tamoxifen and premarin as in a previous Medicine Branch protocol (MB-160C). Among patients with inflammatory carcinoma of the breast, pathologic complete responders will receive irradiation to the breast and regional lymph nodes; convertible partial responders and clinical complete responders with residual disease on biopsy will undergo surgical resection of bulk disease followed by irradiation of the chest wall and regional lymph nodes excluding the axilla. Both groups of responders will be randomized to receive either systemic consolidation therapy with high dose melphalan (180 mg/M2 total dose over 3 days) and autologous bone marrow transplantation followed by maintenance therapy or maintenance therapy alone. Complete responders in this noninflammatory group will not receive further therapy since, historically, they have done well following induction and local therapy, with maintenance therapy alone. Patients with metastatic breast cancer will be assessed for response throughout induction therapy. Complete and convertable partial responders will receive consolidative therapy and be randomized to ABMT followed by 6 months of maintenance therapy vs. maintenance alone.
Patients with Zollinger-Ellison Syndrome suffer from ulcers of the upper gastrointestinal tract, higher than normal levels of gastric acid, and tumors of the pancreas known as non-beta islet cell tumors. Prior to the use of drugs to cure the ulcers, patients typically died due to severe ulcers. Because of such effective drugs to treat the ulcers it is more common to see patients dying due to the pancreatic tumors. The study will observe patients suffering from Zollinger-Ellison Syndrome and non-beta islet cell tumors and determine the effectiveness of combined chemotherapy with streptozotocin, 5-fluorouracil, and doxorubicin.
