Adjuvant clodronate therapy in patients with locally advanced breast cancer--long term results of a double blind randomized trial. Slovak Clodronate Collaborative Group.

Between March 1990 and May 1993 seventy three patients with previously untreated breast cancer, Stage III or IV without osseal metastases were randomized to sodium clodronate 1600 mg daily p.o.(arm A = 37 patients) or placebo (arm B = 36 patients) over 2 years, additionally to standard therapy.

Intensive combination chemotherapy (TTL-I protocol) of large cell and immunoblastic lymphomas--long-term observation.

Fifty patients with advanced (Stage III and IV) large cell and immunoblastic lymphoma were treated with eight 4-week courses of chemotherapy. The first two identical A courses were composed of high dose cyclophosphamide, vincristine, 5-day administration of bleomycin, 2-week prednisone, and methotrexate with calcium leucovorin. The next two "B" courses were composed of vincristine, 3-day administration of doxorubicin together with bleomycin, and prednisone.

Comparison of two non-cross-resistant combinations (ABVP/LOPP) with COPP plus bleomycin in the treatment of advanced Hodgkin's disease.

Eighty patients with advanced Hodgkin's disease were randomized either to treatment with combination of doxorubicin, bleomycin, vinblastine, and prednisone (ABVP), alternating with lomustine, vincristine, procarbazine, and prednisone (LOPP)--Group A, or to combination of cyclophosphamide, vincristine, procarbazine, prednisone, and low dose of bleomycin (COPP-Bleo)--Group B. Thirty-nine out of 41 patients (95%) in Group A achieved complete remission (CR) as compared to 25 CR in 39 patients (64%) in Group B. Patients with systemic symptoms, bulky disease, and nodular sclerosis achieved significantly more CR after treatment with ABVP/LOPP regimen than with COPP-Bleo regimen.

Treatment of advanced Hodgkin's disease with modified MOPP regimens. A long-term observation.

Fifty-three patients with advanced Hodgkin's disease, most of them previously treated, received 8 to 16 courses of modified MOPP regimens (nitrogen mustard replaced by trichlormethine in arm A, with addition of vinblastine to the 4-drug regimen in arm B, and alternation of three drugs--trichlormethine, vincristine, and prednisone--with probably non-cross resistant two drugs--vinblastine and procarbazine in arm C). Thirty patients (57%) achieved complete remission. Higher complete remission rate and longer survival was recorded in patients treated with 5-drug regimens (arms B and C) as compared to the 4-drug regimen (arm A), but the differences were not significant.

The status of nuclear medicine techniques in the diagnosis of bone metastases in breast cancer.

In this article, the authors present their experience with the diagnosis of bone metastases in patients with breast cancer using bone scintigraphy with 99mTc phosphonate and radioimmunological determination of carcinoembryonic antigen (CEA) and tissue polypeptic antigen (TPA). In a group of 395 patients, there was agreement between tumour markers (CEA, TPA) and the results of bone scintigraphy in 331 cases (84%)--negative in 193 cases (49%) and positive (i.e.
