[Neoadjuvant chemotherapy, with mitoxantrone, cyclophosphamide and fluorouracil, in operable breast cancer of intermediate stage: first results of a phase II study in 40 patients].

Forty patients with intermediate stage (T2 > 3 cm-T3, N0-N1) operable breast cancer received neoadjuvant chemotherapy by MCF (mitoxantrone, cyclophosphamide, 5-fluorouracil). Four cycles were administered at 3-week intervals. The obvious hematological toxicity (64% of grade III for the leucocytes and up to 34% of grade IV for the granulocytes) was rapidly reversible and did not hinder completion of the treatment.

[Biochemical characterization of a high-molecular weight alkaline phosphatase in a patient with cholangiocarcinoma (alpha-1 alkaline phosphatase)].

The authors analysed the alkaline phosphatases present in the serum of a patient with cholangiocarcinoma. The electrophoretic analysis on cellulose acetate revealed two bands of AP activity in positions alpha 1 and alpha 2. The more anodic of the isoenzymes of AP presented most of the features of the high molecular weight isoenzyme found in human bile, except that it was non-competitively inhibited by L-homoarginine.
