A phase 2 study of the combination of gemcitabine and cisplatin in patients with locally advanced or metastatic breast cancer previously treated with anthracyclines with/without taxanes.

BACKGROUND AND OBJECTIVES: Many patients with relapsed metastatic breast cancer are pre-treated with taxanes and anthracyclines, which are usually given in the neoadjuvant/adjuvant setting or as first-line treatment for metastatic disease. The primary objective of this study was to determine the overall response rate for combination treatment with gemcitabine and cisplatin in patients with locally advanced or metastatic breast cancer who had relapsed after receiving one adjuvant/neoadjuvant or first-line metastatic chemotherapy regimen containing an anthracycline with/without a taxane. Secondary endpoints included duration of response, time to progression, one-year survival probability, and toxicity. DESIGN AND SETTING: A single-arm, open-label, phase 2 study conducted at 17 investigative sites in Egypt. PATIENTS AND METHODS: treatment consisted of gemcitabine (1250 mg/m2) on Days 1 and 8 and cisplatin (70 mg/m2) on Day 1 of each 21-day cycle. Treatment continued until disease progression or a maximum of 6 cycles. RESULTS: Of 144 patients all were evaluable for safety and 132 patients were evaluable for efficacy. The overall response rate was 33.3% and 45.5% of the patients with stable disease as their best response. The median time-to-progression was 5.1 months and the one-year survival probability was 73%. The most common grade 3/4 adverse events were nausea/vomiting (20.1%), neutropenia (19.4%), anemia (13.9%), asthenia (11.1%), diarrhea (9.7%), stomatitis (7.6%), leucopenia (7.6%), and thrombocytopenia (6.2%). twelve (8.3%) patients had serious adverse events. CONCLUSIONS: The results of this study indicate that gemcitabine and cisplatin were active and generally well tolerated in pretreated patients with locally advanced or metastatic breast cancer.

Primary cardiac Burkitt lymphoma in a child.

Primary cardiac lymphoma (PCL) is a rare and usually fatal malignancy, seldom reported in children. This report describes the case of a 10-year-old boy who presented with multiple intracardiac masses which, when biopsied, proved to be small non-cleaved cell (Burkitt's) lymphoma. The first two cycles of chemotherapy according to the LMB 96 protocol were given under close cardiological supervision, with good response. The treatment was then continued with full-dose chemotherapy, without any cardiological complication. The patient who was treated by chemotherapy alone remains in complete remission 36 months after the end of treatment and can presently be considered as cured, without late cardiac effect.
