Health-related quality of life, symptom burden, and comorbidity in long-term survivors of acute promyelocytic leukemia.

The objective of this study was to investigate health-related quality of life (HRQOL), symptom burden, and comorbidity profile in long-term acute promyelocytic leukemia (APL) survivors treated with standard chemotherapy. Overall, 307 long-term APL survivors were invited to participate. HRQOL was assessed with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and compared with that of age and sex-matched controls from the general population. Symptom burden was assessed with the MD Anderson Symptom Inventory (MDASI) questionnaire and comorbidity profile was also investigated. Median follow-up time since diagnosis was 14.3 years (interquartile range: 11.1-16.9 years). APL survivors had a statistically and clinically meaningful worse score for the role physical scale of the SF-36 (-9.5; 95% CI, -15.7 to -3.2, P = 0.003) than their peers in the general population. Fatigue was reported as moderate to severe by 29% of patients and 84.4% reported at least one comorbidity. Prevalence of comorbidity in APL survivors was higher than that reported by the general population. Also, marked variations were found in the HRQOL profile by number of comorbidities. Even many years after treatment ends, APL survivors treated with standard chemotherapy do not fully recover as they report HRQOL limitations and a substantial burden of symptoms.

Randomized phase III trial of retinoic acid and arsenic trioxide versus retinoic acid and chemotherapy in patients with acute promyelocytic leukemia: health-related quality-of-life outcomes.

PURPOSE: A randomized clinical trial compared efficacy and toxicity of standard all-trans-retinoic acid (ATRA) plus chemotherapy versus ATRA plus arsenic trioxide in patients with newly diagnosed, low- or intermediate-risk acute promyelocytic leukemia (APL). Here, we report health-related quality-of-life (HRQOL) results. PATIENTS AND METHODS: HRQOL was a secondary end point of this trial. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 was used to assess HRQOL at end of induction and after consolidation therapy. All analyses were based on 156 patients who received at least one dose of treatment, with groups defined according to randomly assigned treatment. Primary analysis was performed, estimating mean HRQOL score over time and differences between treatment arms using a linear mixed model. RESULTS: Overall, 162 patients age 18 to 70 years were enrolled. Of these, 150 and 142 patients were evaluable for HRQOL after induction therapy and third consolidation course, respectively. Overall compliance with HRQOL forms was 80.1%. The largest difference, favoring patients treated with ATRA plus arsenic trioxide, was found for fatigue severity (mean score difference, -9.3; 95% CI, -17.8 to -0.7; P = .034) at end of induction therapy. This difference was also clinically relevant. HRQOL differences between treatment arms at end of consolidation showed that for several scales, differences between treatment arms were marginal. CONCLUSION: Overall, current HRQOL findings further support the use of ATRA plus arsenic trioxide as preferred first-line treatment in patients with low- or intermediate-risk APL.

Delirium in acute promyelocytic leukemia patients: two case reports.

BACKGROUND: Delirium is a frequently misdiagnosed and inadequately treated neuropsychiatric complication most commonly observed in terminally ill cancer patients. To our knowledge this is the first report describing delirium in two patients aged less than 60 years and enrolled in an intensive chemotherapeutic protocol for acute promyelocytic leukemia. CASE PRESENTATION: Two female Caucasian acute promyelocytic leukemia patients aged 46 and 56 years developed delirium during their induction treatment with all-trans retinoic acid and idarubicin. In both cases symptoms were initially attributed to all-trans retinoic acid that was therefore immediately suspended. In these two patients several situations may have contribute to the delirium: in patient 1 a previous psychiatric disorder, concomitant treatments with steroids and benzodiazepines, a severe infection and central nervous system bleeding while in patient 2 steroid treatment and isolation. In patient 1 delirium was treated with short-term low-doses of haloperidol while in patient 2 non-pharmacologic interventions had a beneficial role. When the diagnosis of delirium was clear, induction treatment was resumed and both patients completed their therapeutic program without any relapse of the psychiatric symptoms. Both patients are alive and in complete remission as far as their leukemia is concerned. CONCLUSIONS: We suggest that patients with acute promyelocytic leukemia eligible to intensive chemotherapy should be carefully evaluated by a multisciplinary team including psychiatrists in order to early recognize symptoms of delirium and avoid inadequate treatments. In case of delirium, both pharmacologic and non-pharmacologic interventions may be considered.
