A novel scoring system to predict the incidence of invasive fungal disease in salvage chemotherapies for malignant lymphoma

The requirement of antifungal prophylaxis has not been established in the chemotherapies for malignant lymphoma. This study was conducted to explore the incidence of invasive fungal diseases (IFD) and their risk factors in patients receiving salvage therapies for malignant lymphoma. We retrospectively analyzed 177 consecutive patients who received these therapies (705 courses in total) at our institute. IFD were observed in 16 courses and the incidence was 2.3 %. A multivariate analysis showed that the factors associated with IFD were primary refractoriness (adjusted odds ratio (aOR), 4.22; 95 % confidence interval (CI), 1.38-13.0; p value = 0.012), two (aOR, 10.5, 95 % CI, 1.20-91.7; p = 0.033) or more (aOR, 26.2; 95 % CI, 3.27-210; p = 0.002) previous treatment lines, and the minimum neutrophil count during the therapies equal to or less than 500/μL (aOR, 9.69; 95 % CI, 1.25-74.9; p = 0.030). Using these factors, we created the IFD scoring model by assigning one point to each of primary refractoriness, two previous treatment lines and treatment that caused neutropenia (≤500/μL minimal neutrophil count) and two points to three or more previous treatment lines. The IFD incidence of lower risk group (IFD score <3) was 0.19 % and that of higher (IFD score ≥3) was 9.0 %. In conclusion, adequate prophylaxis for IFD might be required for patients with primary refractoriness, repeated therapies, or therapies which cause neutropenia. Furthermore, the IFD scoring model of this study underscores the need to account for disease and host factors in determining administration of adequate prophylaxis in salvage treatments for malignant lymphoma.

Ifosfamide continuous infusion plus etoposide in the treatment of elderly patients with aggressive lymphoma: a phase II study

A prospective phase II study was performed to evaluate efficacy and toxicity of continuous infusion ifosfamide plus etoposide combination in elderly patients (older than 70 years) with intermediate or high grade non Hodgkin's lymphoma. Chemotherapy was administered with mesna in order to avoid hemorrhagic cystitis. The 21 patients included were either unable to receive the usual front-line chemotherapy given in our institution or relapsing after or not responding to conventional chemotherapy. Only one out of 97 courses of chemotherapy was followed by serious complication consisting in non-lethal pneumonitis. Four out of seven previously untreated patients and five patients treated in first relapse achieved complete response (75 per cent). Out of nine refractory or previously multi-treated patients, only one achieved complete response. We conclude that combination of continuous infusion ifosfamide plus etoposide deserves to be evaluated on a larger scale so that the optimum doses and schedule may be defined.

Etoposide, ifosfamide, and methotrexate with or without bleomycin in refractory or recurrent lymphomas

The prognosis of patients with refractory or relapsed malignant lymphoma is poor. To improve the outcome of such patients, a therapeutic regimen of VIM +/- B (etoposide/ifosfamide plus mesna/methotrexate/ with or without bleomycin) was administered. Of 47 patients treated, 15 had relapsed following complete remission (CR) after first-line chemotherapy, 28 had failed to achieve CR with first-line therapy, and four failed to respond to multiple salvage regimens. All patients had received extensive prior chemotherapy, and 36 had received combinations containing doxorubicin. Eight patients had low-grade non-Hodgkin's lymphoma (NHL), 28 had high-grade NHL, and 11 patients had Hodgkin's disease. Overall response rate was 87%, with 45% CR and 42% partial remission (PR). Median relapse-free interval was 8 months in patients with CR and 6 months in those with PR. Of patients with CR, 43% were predicted to be without relapse at 2 years and 31% at 5 years. Median survival time for all patients treated with 14 months-22 months for those with CR and 10 months for those with PR. Probability of survival at 2 years was 30% in all patients, 50% in patients with CR, and 15% in those with PR. VIM +/- B appears to be effective against refractory or recurrent lymphoma, resulting in response in a large number of patients and long-term survival and possible cure in a small but significant number. Results indicate that VIM +/- B is particularly effective in patients with high-grade NHL who have responded suboptimally to primary therapy.
