Quality of life gains in frail and intermediate-fit patients with multiple Myeloma: Findings from the prospective HOVON123 clinical trial.

BACKGROUND: Frailty in newly-diagnosed multiple myeloma (NDMM) patients is associated with treatment-related toxicity, which negatively affects health-related quality of life (HRQoL). Currently, data on changes in HRQoL of frail and intermediate-fit MM patients during active treatment and post-treatment follow-up are absent. METHODS: The HOVON123 study (NTR4244) was a phase II trial in which NDMM patients ≥ 75 years were treated with nine dose-adjusted cycles of Melphalan-Prednisone-Bortezomib (MPV). Two HRQoL instruments (EORTC QLQ-C30 and -MY20) were obtained before start of treatment, after 3 and 9 months of treatment and 6 and 12 months after treatment for patients who did not yet start second-line treatment. HRQoL changes and/or differences in frail and intermediate-fit patients (IMWG frailty score) were reported only when both statistically significant (p < 0.005) and clinically relevant (>MID). RESULTS: 137 frail and 71 intermediate-fit patients were included in the analysis. Compliance was high and comparable in both groups. At baseline, frail patients reported lower global health status, lower physical functioning scores and more fatigue and pain compared to intermediate-fit patients. Both groups improved in global health status and future perspective; polyneuropathy complaints worsened over time. Frail patients improved over time in physical functioning, fatigue and pain. Improvement in global health status occurred earlier than in intermediate-fit patients. CONCLUSION: HRQoL improved during anti-myeloma treatment in both intermediate-fit and frail MM patients. In frail patients, improvement occurred faster and, in more domains, which was retained during follow-up. This implies that physicians should not withhold safe and effective therapies from frail patients in fear of HRQoL deterioration.

Quality of life of patients with chronic lymphocytic leukaemia in the Netherlands: results of a longitudinal multicentre study.

PURPOSE: To describe the health-related quality of life (HRQoL) of an unselected population of patients with chronic lymphocytic leukaemia (CLL) including untreated patients. METHODS: HRQoL was measured by the EORTC QLQ-C30 including the CLL16 module, EQ-5D, and VAS in an observational study over multiple years. All HRQoL measurements per patient were connected and analysed using area under the curve analysis over the entire study duration. The total patient group was compared with the general population, and three groups of CLL patients were described separately, i.e. patients without any active treatment ("watch and wait"), chlorambucil treatment only, and patients with other treatment(s). RESULTS: HRQoL in the total group of CLL patients was compromised when compared with age- and gender-matched norm scores of the general population. CLL patients scored statistically worse on the VAS and utility score of the EQ-5D, all functioning scales of the EORTC QLQ-C30, and the symptoms of fatigue, dyspnoea, sleeping disturbance, appetite loss, and financial difficulties. In untreated patients, the HRQoL was slightly reduced. In all treatment stages, HRQoL was compromised considerably. Patients treated with chlorambucil only scored worse on the EORTC QLQ-C30 than patients who were treated with other treatments with regard to emotional functioning, cognitive functioning, bruises, uncomfortable stomach, and apathy. CONCLUSIONS: CLL patients differ most from the general population on role functioning, fatigue, concerns about future health, and having not enough energy. Once treatment is indicated, HRQoL becomes considerably compromised. This applies to all treatments, including chlorambucil, which is considered to be a mild treatment.

Real-world costs of chronic lymphocytic leukaemia in the Netherlands.

We performed a comprehensive cost calculation identifying the main cost drivers of treatment of chronic lymphocytic leukaemia in daily practice. In our observational study 160 patient charts were reviewed repeatedly to assess the treatment strategies from diagnosis till the study end. Ninety-seven patients (61%) received ≥1 treatment lines during an average follow-up time of 6.4 years. The average total costs per patient were €41,417 (€539 per month). The costs varied considerably between treatment groups and between treatment lines. Although patients were treated with expensive chemo(immuno-)therapy, the main cost driver was inpatient days for other reasons than administration of chemo(immuno-)therapy.

Analysis of docetaxel therapy in elderly (≥70 years) castration resistant prostate cancer patients enrolled in the Netherlands Prostate Study.

BACKGROUND: Prostate cancer truly is an age-associated disease. Due to the increased life expectancy and more sensitive diagnostic techniques in the Western world, prostate cancer is diagnosed more frequently and with rapidly increasing incidence and prevalence rates. However, age above 65 or 70 years has been an exclusion criterion in clinical trials for decades and the knowledge about chemotherapy tolerance in elderly is limited. METHODS: We performed a retrospective analysis of data acquired from the recently published Netherlands Prostate Study (NePro) to evaluate the influence of advanced age on docetaxel therapy in elderly men (>70 years) with castration resistant prostate cancer (CRPC) and bone metastases. Statistical analyses were performed stratified for age into four categories: <70 (n=315), 70-74 (n=150), 75-79 (n=85), and ≥80 years old (n=18). RESULTS: We analysed 568 patients (median age 68.1 years, range 46-89 years, 44.5% aged ≥70 years). There was no relation between dosage and age (p=0.60). We found no significant differences between the number of dose reductions, time to progression (TTP), overall survival, chemotherapy tolerance and toxicity up to the age of 80 years. However, when compared to younger men, men aged 80 years or above more frequently experienced grade 3/4 toxicity and were five times less likely to complete the first three treatment cycles at the intended dose (Odds ratio (OR) 5.34, p=0.0052) and showed decreased overall survival (15.3 months versus 24.5 months in <80 years group, p=0.020). CONCLUSION: In CRPC patients up to the age of 80 years, docetaxel chemotherapy is well tolerated, with toxicity levels and TTP comparable to those of younger patients. For chemotherapeutic treatment of patients above the age of 80 years an individual assessment should be made.

Randomised Phase III study of biweekly 24-h infusion of high-dose 5FU with folinic acid and oxaliplatin versus monthly plus 5-FU/folinic acid in first-line treatment of advanced colorectal cancer.

BACKGROUND: A phase III study was started to compare oxaliplatin/5FU/LV in the first-line with bolus FU/LV in metastatic colorectal cancer. PATIENTS AND METHODS: 302 patients were randomised and received bolus 5-FU 425 mg/m(2) day 1-5, FA 20 mg/m(2) day 1-5, q 4 wk or oxaliplatin 85 mg/m(2), 2 h-infusion, FA 200 mg/m(2), 1-h infusion. 5-FU 2600 mg/m(2), 24-h infusion day 1, q 2 wk. The primary endpoint was response rate (RR). RESULTS: The median follow-up is 31.8 months, 90.4% of the patients have died. Confirmed RR, progression free survival (PFS; months) and median overall survival (OS; months) in 5FU/LV versus 5FU/LV/oxaliplatin were respectively 18.5% versus (vs) 33.8% (P = 0.004), 5.6 vs 6.7 (P = 0.016) and 13.3 vs 13.8 (P = 0.619). In the 5FU/LV/oxaliplatin arm less grade (3/4) toxicity was measured for diarrhoea, stomatitis, an increase in idiosyncratic side effects and neurosensory events compared with 5FU/LV. The quality of life (QOL) was equal in both arms. Second line treatment was given in 62% of the patients, crossover of 5FU/LV to 5FU/LV/oxaliplatin occurred in 14%. CONCLUSIONS: Oxaliplatin in the first-line resulted in an increased RR and PFS with less grade 3/4 mucositis/diarrhoea compared with 5FU/LV alone. Idiosyncratic side effects deserve attention with oxaliplatin. Despite a low treatment cross over rate, OS in both groups was comparable.

First-line gemcitabine with cisplatin or epirubicin in advanced non-small-cell lung cancer: a phase III trial.

The purpose of our study was to compare progression-free survival and quality of life (QOL) after cisplatin-gemcitabine (CG) or epirubicin-gemcitabine (EG) in chemotherapy-naive patients with unresectable non-small-cell lung cancer. Patients (n=240) were randomised to receive gemcitabine 1125 mg x m(-2) (days 1 and 8) plus either cisplatin 80 mg x m(-2) (day 2) or epirubicin 100 mg x m(-2) (day 1) every 3 weeks for a maximum of five cycles. Eligible patients had normal organ functions and Eastern Cooperative Oncology Group performance status

Recent progress in the diagnosis of fungal infections in the immunocompromised host.

The management of invasive fungal infections has been hampered by the inability to diagnose the infection at an early stage of disease. Although proving the presence of infection by histology and culture remains the cornerstone of the diagnosis, non-culture based methods are becoming available that enable early detection. Molecular diagnosis by PCR appears very promising since fungal DNA can be detected in the blood of infected patients before conventional methods. Furthermore, a broad range of yeasts and molds can be identified to species level. Automation of sample preparation and use of real-time PCR systems will help standardize the procedure and reduce false positive results due to contamination. Promising assays for the detection of fungal antigens in serum have been commercialized, including detection systems for mannan (Candida) and galactomannan (Aspergillus). Circulating antigens can be detected at an early stage of infection, often before the onset of clinical symptoms. Antigen detection is limited to detecting only one genus and not enabling speciation. Furthermore, both PCR and antigen detection can be used to monitor the response of patients to treatment with anti-fungal agents. Although prospective screening of high-risk patients for the presence of circulating markers of fungal infection appears to be an appropriate strategy, studies are needed to help to establish the optimal approach to managing invasive fungal infections that incorporates the benefits of non-culture based methods.

Defining opportunistic invasive fungal infections in immunocompromised patients with cancer and hematopoietic stem cell transplants: an international consensus.

During the past several decades, there has been a steady increase in the frequency of opportunistic invasive fungal infections (IFIs) in immunocompromised patients. However, there is substantial controversy concerning optimal diagnostic criteria for these IFIs. Therefore, members of the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group formed a consensus committee to develop standard definitions for IFIs for clinical research. On the basis of a review of literature and an international consensus, a set of research-oriented definitions for the IFIs most often seen and studied in immunocompromised patients with cancer is proposed. Three levels of probability are proposed: "proven," "probable," and "possible." The definitions are intended for use in the context of clinical and/or epidemiological research, not for clinical decision making.

Activity of high-dose epirubicin combined with gemcitabine in advanced non-small-cell lung cancer: a multicenter phase I and II study.

The aim of the study was to evaluate efficacy and tolerance of epirubicin and gemcitabine as first-line chemotherapy in patients with advanced non-small-cell lung cancer. A phase I study was performed with the combination of escalating doses of epirubicin intravenously on day 1 and a fixed dose of gemcitabine on days 1 and 8 of a 21 -day cycle. Eighteen patients were included in the phase I part of the study before the maximum tolerated dose was found. Dose-limiting toxicity was febrile neutropenia. The phase II part of the study was continued with epirubicin 100 mg m(-2) on day 1 and gemcitabine 1125 mg m(-2) on days 1 and 8 of a 21-day cycle. Forty-three chemotherapy-naive patients were included. The median age of the patients was 60 years (range 26-75). Most patients (74%) were in stage IV. Granulocytopenia CTC grade 4 occurred in 32.5% and thrombocytopenia grade 4 in 11.6% of cycles. Febrile neutropenia occurred in six patients. Non-haematological toxicity was mainly mucositis CTC grade 2 and 3 in 35% of patients. The tumour response rate was 49% (95% confidence interval (CI) 35-63%). The median survival time for the patients was 42 weeks (95% CI 13-69).

Tolerance and efficacy of Amphotericin B inhalations for prevention of invasive pulmonary aspergillosis in haematological patients.

The tolerance of aerosolised amphotericin B as prophylaxis against invasive pulmonary aspergillosis was investigated in 61 granulocytopenic periods in 42 patients treated for a haematologic malignancy. Each patient was to receive amphotericin B in doses escalating to 10 mg three times daily (t.i.d.), but only 20 (48%) patients managed to complete the scheduled regimen. One patient tolerated the full dose initially, but had to discontinue treatment when dyspnea developed as a result of pneumonia and acute respiratory distress. Another 22 patients (52%) experienced side effects, including eight (19%) who reported mild coughing and dyspnea but who tolerated the full dose and three (7%) patients whose dose was reduced to 5 mg t.i.d. Another six (14%) patients could tolerate only 5 mg t.i.d., and five (12%) others stopped treatment because of intolerance. Elderly patients (p < 0.05) and those with a history of chronic pulmonary obstructive disease (p = 0.09) were more likely to develop side effects during inhalation. Twelve (28%) patients developed proven of possible invasive fungal infections, but no correlation was established between infection and the total amount of amphotericin B inhaled. Inhalation of aerosolised amphotericin B is poorly tolerated and does not appear useful in preventing invasive pulmonary aspergillosis in granulocytopenic patients.

Continuous infusion of ceftazidime in febrile neutropenic patients with acute myeloid leukemia.

Twelve febrile patients with severe neutropenia, who had undergone aggressive chemotherapy for acute myeloid leukemia, were treated empirically with a continuous infusion of ceftazidime 100 mg/kg/day after a 500 mg loading dose, in order to study the pharmacokinetics of ceftazidime after continuous infusion and to examine the clinical applicability of continuous infusion in this patient population. Three patients had a slight decrease in renal function. All patients attained a steady-state ceftazidime serum level of > 20 micrograms/ml within 180 to 240 min, which was considered effective against most pathogens in neutropenic patients. The median volume of distribution for the patient group was 29.1 l, the elimination half-life was 2.5 h and the clearance of ceftazidime was 7.7 l/h. A subnormal kidney function influenced half-lives and clearance (but not volume of distribution), as expected. When precautions were taken to avoid known interactions between ceftazidime and other compounds to be infused simultaneously, continuous infusion of ceftazidime was applicable for treatment of neutropenic patients without major side effects.
