Fifty-five patients, initially diagnosed as having advanced high grade non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) refractory to first-line treatment or in relapse, were treated with ifosfamide 6 g/m2, infused over 48 h, followed by mitoxantrone 12 mg/m2. The regimen repeated at three-weekly intervals. Of 32 patients with NHL evaluable for response, 10 (31 per cent) achieved complete remission and five partial remission, giving an overall response rate of 47 per cent. Two patients subsequently went on to bone marrow transplant (BMT)--one allogeneic and the other autologous. Of 17 patients with HD evaluable for response, six (35 per cent) achieved complete remission and six partial remission, giving an overall response rate of 71 per cent. Two of this group also went on to BMT (both autografts). The principal toxicity was neutropenia, though central nervous system changes were observed in 10 patients. Given the need to offer alternative treatment of patients in these categories, this combination (I-M) is clearly of value in relapsed patients especially where therapeutic options are limited because of previous multi-drug treatment.
Fifty-seven patients, initially diagnosed as having advanced high grade non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) refractory to first-line treatment or in relapse, were treated with ifosfamide 6 g/m2, infused over 48 h, followed by mitoxantrone 12 mg/m2. The regimen repeated at three-weekly intervals. Of 33 patients with NHL evaluable for response, 10 (30 per cent) achieved complete remission and six partial remission, giving an overall response rate of 48 per cent. Two patients subsequently went on to bone marrow transplant (BMT)--one allogeneic and the other autologous. Of 18 patients with HD evaluable for response, seven (39 per cent) achieved complete remission and six partial remission, giving an overall response rate of 72 per cent. Two of this group also went on to BMT (both autografts). The principal toxicity was neutropenia, though central nervous system changes were observed in 10 patients. The possibility of increasing the safety of the regimen by increasing the time of infusion to 72 h is discussed. Given the need to offer alternative treatment to patients in these categories, this combination (I-M) is of value in relapsed patients, especially where options are limited because of previous multi-drug treatment. Remissions may not be prolonged but allow the effective application of additional intensive treatment including bone marrow transplantation.
Twenty-five patients with either previously untreated advanced Hodgkin's disease (HD) or with relapsed disease were treated with an intensive weekly chemotherapy regimen (ChlOPhEPP-B) in which the myelosuppressive combinations of epirubicin and chlorambucil, and procarbazine and etoposide alternated at two-week intervals, interspersed with vincristine and prednisolone and then vincristine, prednisolone and bleomycin in a four-week cycle. Of the previously untreated patients (n = 14), 12 (86 per cent) showed a complete response (CR); in the previously treated patients (n = 11), CR was achieved in five (46 per cent). Toxicity was predictable and not evidently more severe than with more standard regimens. Neutropenia leading to treatment delay and/or dose reduction was seen in 11 patients (44 per cent) but severe neutropenia (WHO grade 4) was documented in only six patients (24 per cent) for a cumulative total of nine treatment weeks (1.8 per cent of the total treatment time). Dose reductions for neutropenia were applied in relation to 11 of the 379 weekly treatment points (2.9 per cent). Delays in treatment, for any reason, averaged 3.65 weeks per patient. The study demonstrated the feasibility of a more intensive weekly multidrug schedule. This approach may be applicable in the treatment of advanced HD and represents a further option in the strategy of treating relapsed disease.
Failure of patients to attend outpatient clinics is common and costly. In one consultant's general medical and gastrointestinal outpatient clinic, 38% of new patients failed to keep at least one appointment, 17% did not attend for their first outpatient consultation and, of these, 59% failed to keep a second appointment sent to them. Of the patients who did attend for their first consultation 12% did not keep their next two appointments. Failure to attend was more common in men, young patients, patients from certain inner city areas, patients on the lists of certain general practices, and those who had already defaulted once. Possible background reasons for default are discussed, suggestions for further study proposed, and an attempt made to look for ways to reduce the extent of the problem.
