RESUMEN
PURPOSE: The main objective of this study is to gain a deeper understanding of how patients suffering from chronic myeloid leukemia (CML) cope with their illness. The study aims to reconstruct the subjective meaning-making process related to CML in order to gain insights into the impact the disease has on patients' emotions and everyday lives, as well as to explore the psychological impact of their being presented with the chance to suspend their therapy and recover from the disease. METHODS: Data were gathered from a qualitative study conducted in Italy on 158 Italian CML patients. Basing the study on the narrative inquiry approach, the patients were required to describe their patient journey in a qualitative narrative diary. These contained prompts to elicit the free expression of their needs, expectations, and priorities. A lexicographic analysis was carried out with T-LAB software and in particular a thematic analysis of elementary contexts (TAECs) and a word association analysis (WAA). RESULTS: The TAEC detected four thematic clusters related to two factors (temporal frame and contextual setting) that explained the variance among the narratives. The WAA evidenced a wide variety of emotions, both positive and negative, as patients reacted to the possibility of interrupting their therapy. CONCLUSIONS: A better understanding of patients' experiences can offer insights into promoting the development of more sustainable healthcare services and into therapeutic innovation aimed at improving patients' quality of life and at engaging them more in their treatment. The findings of this study can also help make medical professionals more aware of the patient's burden and help them identify potential interactions and emotional levers to improve clinical relationships.

The aim of this study was to investigate the effects of a non-standard, intermittent imatinib treatment in elderly patients with Philadelphia-positive chronic myeloid leukaemia and to answer the question on which dose should be used once a stable optimal response has been achieved. Seventy-six patients aged ⩾65 years in optimal and stable response with ⩾2 years of standard imatinib treatment were enrolled in a study testing a regimen of intermittent imatinib (INTERIM; 1-month on and 1-month off). With a minimum follow-up of 6 years, 16/76 patients (21%) have lost complete cytogenetic response (CCyR) and major molecular response (MMR), and 16 patients (21%) have lost MMR only. All these patients were given imatinib again, the same dose, on the standard schedule and achieved again CCyR and MMR or an even deeper molecular response. The probability of remaining on INTERIM at 6 years was 48% (95% confidence interval 35-59%). Nine patients died in remission. No progressions were recorded. Side effects of continuous treatment were reduced by 50%. In optimal and stable responders, a policy of intermittent imatinib treatment is feasible, is successful in about 50% of patients and is safe, as all the patients who relapsed could be brought back to optimal response.

For almost 10 years imatinib has been the therapeutic standard of chronic myeloid leukemia. The introduction of other tyrosine kinase inhibitors (TKIs) raised a debate on treatment optimization. The debate is still heated: some studies have protocol restrictions or limited follow-up; in other studies, some relevant data are missing. The aim of this report is to provide a comprehensive, long-term, intention-to-treat, analysis of 559 newly diagnosed, chronic-phase, patients treated frontline with imatinib. With a minimum follow-up of 66 months, 65% of patients were still on imatinib, 19% were on alternative treatment, 12% died and 4% were lost to follow-up. The prognostic value of BCR-ABL1 ratio at 3 months (⩽10% in 81% of patients) was confirmed. The prognostic value of complete cytogenetic response and major molecular response at 1 year was confirmed. The 6-year overall survival was 89%, but as 50% of deaths occurred in remission, the 6-year cumulative incidence of leukemia-related death was 5%. The long-term outcome of first-line imatinib was excellent, also because of second-line treatment with other TKIs, but all responses and outcomes were inferior in high-risk patients, suggesting that to optimize treatment results, a specific risk-adapted treatment is needed for such patients.

The importance of early therapy intensification in B-cell CLL (B-CLL) patients remains to be defined. Even though several studies have been published, no randomized trials comparing directly autologous stem cell transplant (ASCT) and the accepted conventional therapy (that is, rituximab, fludarabine and CY; R-FC) have been reported so far. To assess the benefit of a first-line aggressive therapy, we designed a multicenter, randomized, phase 3 trial comparing R-FC and high-dose chemotherapy supported by ASCT in patients under 65 years of age, with stage B(II) or C B-CLL. Primary end point was CR: 96 patients were enrolled (48 in each arm). On an intent-to-treat basis, the CR rates in the ASCT and R-FC arms were 62.5% and 58%, respectively. After 5 years of follow-up, PFS was 60.4% in the ASCT arm and 65.1% in the R-FC arm, time to progression 65.8 and 70.5%, and overall survival 88% vs 88.1%, respectively. Our trial demonstrates, for the first time in a randomized manner, that frontline ASCT does not translate into a survival advantage when compared with benchmark chemoimmunotherapy in B-CLL patients; the possibility of its clinical benefit in certain subgroups remains uncertain.

Acute lymphoblastic leukemia (ALL) in adults is currently associated with an overall survival rate of around 40% at 5 years. This is an unsatisfactory result that makes it imperative to dissect further the biology of the disease in order to identify highly specific therapeutic targets to implement selectively the cure rate. The recognition of discrete ALL subsets followed by the application of risk-oriented therapies has been a major achievement over the past 30 years.
