Hematological recovery and peripheral blood progenitor cell mobilization after induction chemotherapy and GM-CSF plus G-CSF in breast cancer.

In order to determine the effect of GM-CSF plus G-CSF in combination in breast cancer patients receiving an effective induction regimen, we compared hematological recovery and peripheral blood progenitor cell (PBPC) mobilization according to colony-stimulating factor (CSF) support. Forty-three breast cancer patients were treated by TNCF (THP-doxorubicin, vinorelbine, cyclophosphamide, fluorouracil, D1 to D4) with CSF support: 11 patients received GM-CSF (D5 to D14); 16 patients G-CSF (D5 to D14) and 16 patients GM-CSF (D5-D14) plus G-CSF (D10-D14). Between two subsequent cycles, progenitor cells were assessed daily, from D13 to D17.

Acquired angioedema with C1 inhibitor deficiency: is the distinction between type I and type II still relevant?

Background: Acquired angioedemas are divided into type I associated with lymphoproliferation and type II caused by anti-C1-inhibitor antibodies. Recent reports have suggested that this distinction is not so clear-cut, mainly because of the presence of antibodies against the C1 inhibitor in some cases belonging to the type I group. We report herein 2 additional cases of acquired angioedema with anti-C1-inhibitor antibody.

Atopy parameters in asthmatic infants.

We evaluated various atopy parameters in 44 asthmatic infants aged 1-3 years: nonspecific parameters (total IgE and eosinophilia), and specific parameters relative to 21 allergens (specific IgE and skin tests), together with tests of leukotriene release by blood leukocytes (cellular allergen stimulation test; CAST) in the presence of a mixture of 21 allergens. Thus far 17 infants have displayed no sign of atopy, but 27 met at least one criterion. Eight met nonspecific criteria, and the others single or multiple criteria.

Mobilization of peripheral blood progenitor cells after induction chemotherapy (THP-doxorubicin-vinorelbine-cyclophosphamide-fluorouracil) and granulocyte colony-stimulating factor in breast cancer.

In order to evaluate the mobilization of peripheral blood progenitor cells (PBPC) after an effective induction regimen in breast cancer, we performed a study on 15 breast cancer patients. Between January 1995 and June 1996, these patients received TNCF (THP-doxorubicin. vinorelbine, cyclophosphamide, fluorouracil for four days, every 21 days) with G-CSF support (5 microg/kg for 10 days after chemotherapy) to reduce aplasia.
