Cyclophosphamide plus vincristine and prednisone in the treatment of severe pemphigus vulgaris refractory to conventional therapy

Five patients with severe pemphigus vulgaris refractory to conventional therapy with azathioprine and corticosteroids were treated with cyclophosphamide, vincristine and prednisone. One patient was not evaluable, while the remaining four patients showed a complete response. Duration of response was in the range of 13-94 months. Toxicity was mainly represented by alopecia, myelosuppression and gastrointestinal side-effects such as nausea/vomiting. Although cyclophosphamide and vincristine may induce severe side-effects, this association may be useful in controlling severe disease resistant to previous conventional therapies.

The effects of the macrocyclic lactone bryostatin-1 on leukemic cells in vitro.

The macrocyclic lactone bryostatin-1 was found to exert in vitro antineoplastic activity against several leukemic cell lines, including human K562 erythroleukemia, HL60 promyelocytic leukemia, REH and MOLT-4 lymphoblastic leukemias, CCRFCEM lymphoma, KG-1 myeloid leukemia, and murine P388 lymphocytic leukemia. No statistically significant difference in sensitivity to bryostatin-1 was found between adriamycin-resistant P388 and K526 subclones and their sensitive counterparts. Freshly explanted clonogenic leukemic cells showed a variable sensitivity to bryostatin-1 in 10/12 tested samples. The IC50 of clonogenic leukemic cells was 4 × 10–3 M bryostatin-1, and that of normal marrow CFU-GM was…

Analysis of human dysplastic haematopoiesis in long-term bone marrow culture

In this paper we have analysed the behaviour of myelodysplastic marrow in a long-term bone marrow liquid culture system (LTBMC) from eleven patients with myelodysplastic syndromes with regard to cellularity, day-7 and day-14 CFU-GM growth, cluster formation, adherent cells and CFU-F formation. An altered CFU-GM pattern was found in 64% of cases at diagnosis, while normal growth was seen in the remaining cases, all of which were affected by refractory anaemia. The levels of CFU-GM, as well as cellularity, were reduced in myelodysplastic marrows compared to normal controls over the whole duration of LTBMCs. Cases with a normal CFU-GM level at diagnosis also showed pathological behaviour when …

Escalating doses of paclitaxel and epirubicin in combination with cisplatin in advanced ovarian epithelial carcinoma: a phase I–II study

Our objective was to identify a new active three-drug combination regimen consisting of paclitaxel (PTX), epirubicin (EPI) and cisplatin as first-line line chemotherapy for advanced ovarian carcinoma. A phase I study was carried out to evaluate the dose-limiting toxicity (DLT) and the maximally tolerated dose (MTD) of PXT and EPI in combination with a fixed dose of cisplatin every 4 weeks. Side-effects were recorded according to the NCI Common Toxicity Criteria. Patients were treated in cohorts of three with fixed-dose cisplatin 80 mg/m 2 and EPI 80 → 100 mg/ m 2 and PXT 100 → 160 mg/m 2 until DLT was reached. Once MTD was identified, a single-step phase II study was therefore carried out t…

Effect of human granulocyte colony stimulating factor (G-CSF) and reduced glutathione (GSH) on drug-induced leukopenia in golden Syrian hamsters.

Systemic chemotherapy in elderly patients with locally advanced and/or inoperable squamous cell carcinoma of the head and neck: impact of anemia and role of recombinant human erythropoietin

Abstract A review of the incidence and management of anemia in elderly patients with head and neck carcinoma treated with systemic chemotherapy. The role of recombinant human erythropoietin in preventing or correcting chemotherapy-related anemia has been focused. Data concerning the prospective use of recombinant human erythropoietin (rhEpo) in a series of unfit elderly patients (EPs) treated with carboplatin plus 5-fluorouracil. Patients were randomly assigned to receive subcutaneous rhEpo 10,000 U three times per week (TIW) (23 elderly patients) or no treatment (22 control patients). Recombinant hEpo was able to prevent anemia and to reduce transfusional requirements in treated patients a…
