Age, severe comorbidity, functional impairment, and kind of tumour are independently related to shorter survival time in cancer patients.

Acute myeloid leukaemia (AML) is mainly affecting elderly patients. Elderly patients are increasingly affected by impairment of functional status (FS). FS is of prognostic relevance for survival in different tumours. Data for patients with AML are rare. Within a prospective trial we recruited patients with newly diagnosed AML and measured FS by two different methods: Karnofsky performance status (KPS) and instrumental activities of daily living (IADL). Sixty-three patients aged 19-85 years (median 61.1) were included. Twenty-three had prior myelodisplastic syndrome (MDS), 7 favourable, 17 unfavourable karyotype. Fifty received induction chemotherapy, 13 palliative chemotherapy. Median survival was 15.2 months (95% CI, 10.8-22.3) in all patients. Age, cytogenetic risk group, and impaired KPS and IADL significantly influenced median survival in univariate analysis. Impairment of IADL was the single most predictive variable. In multivariate analysis, impairment of IADL Score (HR:4.3, 95% CI 1.7-10.5, P = 0.001) and of KPS (HR:4.8, 95% CI 1.9-12.3, P = 0.001), and unfavourable cytogenetic risk group (HR:6.0, 95% CI 2.5-14.3, P < 0.001) significantly predicted median survival. In patients with AML, FS and not age is a major predictor of survival. The influence of FS is independent from cytogenetic risk group. IADL measurement adds information to KPS. The results have to be confirmed in a large sample of patients.

IADL contributes to global QoL in addition to the known effect of KPS. In addition, co-morbidity independently influences global QoL in elderly cancer patients.

Background: Bendamustine is an alkylator with anticipated antimetabolic activity. It has shown activity in malignant lymphoma, multiple myeloma, and breast cancer. Recognized side-effects are relatively mild with myelosuppression as the dose-limiting toxicity. The CD4/CD8 ratio may be reduced. To what extent the alteration of lymphocytes, especially CD4 + lymphocytes, correlates with an increase in opportunistic infections cannot be definitively answered. Case report: The patient, female, aged 48 years, was suffering from an advanced progressive breast cancer. After initial treatment with several chemotherapies, a cytotoxic therapy was initiated, with bendamustine (150 mg/m 2 ) administered on two consecutive days and repeated every 4 weeks. After five courses, the patient developed Pneumocystis carinii pneumonia (PCP), disclosed in the bronchoalveolar lavage. While receiving bendamustine therapy, the CD4 + and CD8 + lymphocyte counts in the peripheral blood were determined by flow cytometry. The next-to-normal CD4/CD8 ratio before therapy (0,82) had decreased to 0,05 during the therapy mainly due to a decline of CD4 + lymphocyte. The patient was seronegative for human immunodeficiency virus. In spite of high-dose intravenous trimethoprim/sulfamethoxazole and methylprednisolone application, the patient died of a respiratory failure 3 days after PCP was diagnosed. Conclusion: Bendamustine is capable of inducing a reduction in CD4 + lymphocyte counts causing a severe T-lymphocyte-mediated immunosuppression. Measuring CD4 + lymphocyte counts may be helpful in determining the risk of PCP in patients treated with bendamustine.
