Special Issue Information

Dear Colleagues,

Recent years have brought unprecedented progress in the treatment of leukemia and lymphoma. The chemotherapy that used to be the mainstay of anticancer therapy is being increasingly replaced by novel targeted therapies in both lymphoid and myeloid malignancies. Currently, two main strategies are in use, viz., immunotherapy and targeted small agent therapy, with more being approved and even more in clinical and preclinical development. Each tool appears to have its use, with immunotherapy being the most effective treatment for B-cell lymphoma and targeted small agents for indolent B-cell malignancies. In recent years, the treatment of B-cell lymphoid malignancies has been greatly improved by the development of targeted drugs, particularly Bruton’s turosine kinase (BTK) inhibitors, phosphoinositide 3-kinases (PI3K) inhibitors and the BCL-2 inhibitor venetoclax. BTK inhibitors can be irreversible, covalently binding to cysteine 481 in the ATP binding pocket of BTK, or reversible, which bind BTK non-covalently and do not require C481 for their activity. Currently, the first-generation BTK inhibitor ibrutinib and the second-generation inhibitors acalabrutinib and zanubrutinib are approved for the treatment of B-cell malignancies. Immunotherapy strategies encompass a range of different monoclonal antibody-based therapies such as antibody–drug conjugates (ADCs) or bispecific antibodies (BITEs), as well as chimeric antigen receptor (CAR) T-cell therapy, which has revolutionized the treatment of acute lymphoblastic leukemia, aggressive B-cell lymphoma and, more recently, multiple myeloma.

This Special Issue will include both original and review articles on approved targeted therapies, as well as emerging therapies for B-cell leukemia and lymphoma that are currently in preclinical and clinical development.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).

To assess the impact of first-line treatment with targeted agents (TAs) or fludarabine, cyclophosphamide, and rituximab (FCR)-based chemo-immunotherapy (CIT) on overall survival (OS) compared to age- and sex-matched individuals in the general population, we conducted an aggregated analysis of phase 3 clinical trials, including the two FLAIR sub-studies, ECOG1912, and CLL13 trials. The restricted mean survival time (RMST), an alternative measure in outcome analyses capturing OS changes over the entire history of the disease, was used to minimize biases associated with the short follow-up time of trials. Patients treated with TAs demonstrated a higher 5-year RMST (58.1 months; 95% CI: 57.4 to 58.8) compared to those treated with CIT (5-year RMST, 56.9 months; 95% CI: 56.7–58.2). Furthermore, the OS comparison of treatment groups with the AGMGP suggests that TAs may mitigate the impact of CLL on OS during the first five years post-treatment initiation. In summary, the 5-year RMST difference was −0.4 months (95% CI: −0.8 to 0.2; p = 0.10) when comparing CLL patients treated with TAs to the Italian age- and gender-matched general population (AGMGP). A similar trend was observed when CLL patients treated with TAs were compared to the US AGMGP (5-year RMST difference, 0.3 months; 95% CI: −0.1 to 0.9; p = 0.12). In contrast, CLL patients treated with FCR exhibited sustained OS differences when compared to both the Italian cohort (5-year RMST difference: −1.6 months; 95% CI: −2.4 to −0.9; p < 0.0001) and the US AGMGP cohort (5-year RMST difference: −0.9 months; 95% CI: −1.7 to −0.2; p = 0.015). Although these results support TAs as the preferred first-line treatment for younger CLL patients, it is crucial to acknowledge that variations in patient selection criteria and clinical profiles across clinical trials necessitate a cautious interpretation of these findings that should be viewed as directional and hypothesis-generating. A longer follow-up is needed to assess the survival improvement of younger CLL patients treated with TAs relative to the AGMGP. Full article
