Health-related quality of life in patients with chronic myeloid leukemia receiving first-line therapy with nilotinib.

BACKGROUND: Although a wealth of efficacy and safety data is available for many tyrosine kinase inhibitors used in chronic myeloid leukemia (CML), there is a dearth of information on their impact on patients' health-related quality of life (HRQOL). The primary objective of this study was to evaluate HRQOL and fatigue outcomes in patients with CML receiving first-line therapy with nilotinib. METHODS: This was a multicenter, prospective study enrolling 130 patients with chronic-phase CML. HRQOL and fatigue were evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and its validated Fatigue module at the baseline and then at 3, 6, 12, 18, and 24 months. The primary prespecified HRQOL endpoints defined in the study protocol for longitudinal analysis were the Physical Functioning, Social Functioning, Role Functioning, and Fatigue scales. The remaining scales were investigated on an exploratory basis. RESULTS: The rate of baseline compliance with the HRQOL assessment was 95.4% (124 of 130), and the rate of overall compliance with HRQOL forms was 91%. Among the 4 prespecified primary HRQOL endpoints, statistically significant improvements over time were found for Physical Functioning (P = .013), Role Functioning (P = .004), and Fatigue (P < .001). Clinically meaningful improvements were found already 3 months after the treatment start. The baseline patient self-reported fatigue severity was an independent predictive factor for the achievement of a major molecular response with an odds ratio of 0.960 (95% confidence interval, 0.934-0.988; P = .005). CONCLUSIONS: For most patients, HRQOL improvements with nilotinib occur during the early phase of therapy and are maintained over time. Also, a more systematic HRQOL evaluation during the diagnostic workup of CML may help to predict clinical outcomes. Cancer 2018;124:2228-37. © 2018 American Cancer Society.

Nilotinib 300 mg twice daily: an academic single-arm study of newly diagnosed chronic phase chronic myeloid leukemia patients.

The introduction and the extended clinical use of nilotinib in the first-line treatment of chronic myeloid leukemia have been based on company-sponsored trials. Independent confirmations are extremely important. We report an investigator-sponsored study of nilotinib 300 mg twice daily in 130 chronic myeloid leukemia patients in early chronic phase. A deep molecular response was achieved in 46% (MR4.0) and 17% (MR4.5) of patients at 2 years; 58% of the enrolled patients achieved a MR4.0 at least once, with a sustained MR4.0 in 52% of them. With a median observation of 29 months (range 24-37 months), 77% of patients were still on treatment with nilotinib. The reasons for permanent discontinuation were: 3% progression, 5% failure or suboptimal response, 8% adverse events, 1% treatment-free remission, and 5% other reasons. Thirteen thrombotic arterial events were reported in 12 patients. A prospective evaluation of metabolic effects showed an increase of fasting glucose without significant variations of glycated hemoglobin, an increase of total cholesterol (both low density lipoprotein and high density lipoprotein fractions) and a decrease of triglycerides. This study confirms a high and rapid efficacy of nilotinib 300 mg twice daily and provides detailed information on the type and incidence of non-hematologic and metabolic adverse events (clinicaltrials.gov identifier: 01535391).

Personal history and quality of life in chronic myeloid leukemia patients: a cross-sectional study using narrative medicine and quantitative analysis.

BACKGROUND: Tyrosine kinase inhibitors (TKIs) drastically changed the outcome of patients diagnosed with chronic myeloid leukemia (CML). Several reports indicated the advantage of continue long-term adherence associated with positive outcome. Therefore, it is important to better understand from the patient's standpoint the experience of living with the disease and the related treatment. OBJECTIVES: In this study, quantitative analysis and narrative medicine were combined to get insights on this issue in a population of 257 patients with CML in chronic phase treated with TKIs (43 % men, with a median age of 58 years, 27 % aged 31-50 years), followed for a median time of 5 years. Sixty-one percent of patients enrolled were treated in first line, whereas 37 % were treated in second line. RESULTS: The results showed more positive perceptions and acceptance in males compared to females, without impact of disease on relationships. Level of positive acceptance was more evident in elderly compared to younger patients, with a close connection with median time from diagnosis. Overall, female patients reported negative perceptions and an impact of disease on family daily living. The majority of patients understood the importance of continue adherence to treatment, with 27 % resulting less adherent (60 % for forgetfulness), even if well informed and supported by his/her physician. DISCUSSION AND CONCLUSIONS: Narrative medicine, in association to quantitative analysis, can help physicians to understand needs of their patients in order to improve communication.

Ruxolitinib - better prognostic impact in low-intermediate 1 risk score: evaluation of the 'rete ematologica pugliese' (REP) in primary and secondary myelofibrosis.

We evaluated ruxolitinib in 65 patients with myelofibrosis according to age, sex, time of diagnosis, grade of fibrosis, prognostic score risk, Janus kinase (JAK) status, primary or secondary myelofibrosis, previous treatment, and dosage. Outcome measures were response rate, time to response, duration of response, and event-free survival and survival. Kaplan and Meier curves show a significant difference in event-free survival according to the prognostic score, in favor of patients with low int1 (p = 0.0009). The Cox stepwise model confirmed the result, the int2 high-risk score being the most powerful negative independent parameter (0.001), followed by JAK (0.008); other parameters, such as diagnosis more than 5 years earlier, grade III-IV fibrosis, and ruxolitinib dose have a negligible impact. Time to response was shorter (p = 0.001) in primary myelofibrosis. In conclusion, ruxolitinib is effective, with a better outcome in patients with a low-int1 risk score. This may suggest considering an earlier administration in the disease course.
