Acute promyelocytic leukaemia (APL) in the elderly patient

SUMMARY

The prognosis of acute promyelocytic leukaemia has passed from nearly desperate to highly curative over the last 40 years due to better understanding of the biology of the disease, the introduction of anthracyclines, all-trans-retinoic acid (ATRA), arsenic trioxide (ATO) and the implementation of better supportive care during the treatment. If this also holds true for older patients will be discussed in this review.

Long-term treatment-free molecular remission in a FIP1L1-PDGFRA positive myeloid/lymphoid neoplasm with eosinophilia after Imatinib discontinuation

SUMMARY

A 47-year-old patient was diagnosed with FIP1L1-PDGFRA-positive myeloid/lymphoid neoplasm with eosinophilia (F/P+ MLN-eo) and was successfully treated with Imatinib, achieving a sustained molecular treatment free remission (TFR) persisting three years after discontinuation.

Chimeric antigen receptor T-cells: a new therapeutic option for relapsed/refractory B-cell malignancies and beyond

Chimeric antigen receptor (CAR) T-cell therapy is a new cancer immunotherapy targeting specific cell surface antigens. This type of adoptive cell immunotherapy has been a breakthrough in the treatment of aggressive B-cell lymphoma and B-cell precursor acute lymphoblastic leukaemia (ALL) and is currently also being studied in other cancer types, including multiple myeloma and chronic lymphocytic leukaemia. This review will discuss the recent clinical developments and future perspectives of CAR T-cell therapy, with a focus on the clinical trials that led to the FDA and EMA approval of tisagenlecleucel (Kymriah®, Novartis) and axicabtagene ciloleucel (Yescarta®, Gilead) for the treatment of childhood/adult relapsed/refractory (r/r) B-cell precursor ALL and aggressive B-cell non-Hodgkin lymphoma.

Extracorporeal photochemotherapy for graft-versus-host disease: Where we are now and where we are going!

SUMMARY

Graft-versus-host disease remains the leading cause of morbidity, non-relapse mortality and treatment failure after allogeneic haematopoietic stem cell transplantation. So far, steroids are the first line treatment, but around 40% of patients become steroid-resistant or fail to respond at a safe dose. Patients who fail to respond to the initial therapy have a dismal prognosis, and no standard treatment is well established for them to date. Treatments that modulate the immune system rather than directly suppressing its function, although not dampening a potential graft-versus-malignancy effect, would therefore be highly desirable, and extracorporeal photopheresis appeared as being a good candidate to fill in these criteria. Multiple reports of treatments in both paediatric and adult patients with graft-versus-host disease have been published, and the overall favourable profile compared with other available immunosuppressive therapies continues to make extracorporeal photopheresis appealing despite all of the unknowns. In this article, we review the use of extracorporeal photopheresis for the treatment of graft-versus-host disease, including technical aspects, mechanism of action, safety profile and clinical efficacy data.
