Prognostic and therapeutic role of targetable lesions in B-lineage acute lymphoblastic leukemia without recurrent fusion genes.

To shed light into the molecular bases of B-lineage acute lymphoblastic leukemia lacking known fusion transcripts, i.e. BCR-ABL1, ETV6-RUNX1, E2A-PBX1, and MLL rearrangements (B-NEG ALL) and the differences between children, adolescents/young adults (AYA) and adults, we analyzed 168 B-NEG ALLs by genome-wide technologies.

A good manufacturing practice method to ex vivo expand natural killer cells for clinical use.

Background: Great interest has been raised recently by the design of new adoptive immunotherapeutic strategies based on the in vivo infusion of ex vivo-expanded and activated natural killer (NK) cells. The development of good manufacturing practice (GMP) methods for the efficient production of fully functional NK cells is mandatory for clinical application.

Materials And Methods: Peripheral blood mononuclear cells were obtained by leukapheresis and processed in the GMP facility.

Immunophenotypic and functional characterization of ex vivo expanded natural killer cells for clinical use in acute lymphoblastic leukemia patients.

The management of acute lymphoblastic leukemia (ALL) patients has witnessed profound changes in recent years. Nonetheless, most patients tend to relapse, underlining the need for new therapeutic approaches. The anti-leukemic potential of natural killer (NK) cells has over the years raised considerable interest.

Ovarian cancer cytoreduction induces changes in T cell population subsets reducing immunosuppression.

Surgery is the primary therapeutic strategy for most solid tumours; however, modern oncology has established that neoplasms are frequently systemic diseases. Being however a local treatment, the mechanisms through which surgery plays its systemic role remain unknown. We have investigated the influence of cytoreduction on the immune system of primary and recurrent ovarian cancer.

RFA strongly modulates the immune system and anti-tumor immune responses in metastatic liver patients.

Radiofrequency tumor ablation (RFA) is a therapeutic modality for liver cancer patients inducing localized tumor necrosis with maximal preservation of normal liver parenchyma. We investigated the immunomodulatory effects exerted by RFA treatment in liver cancer patients with metastatic liver lesions (13 patients) or hepatocellular carcinoma (HCC) (4 patients). Analysis of lymphocyte subsets by flow cytometry revealed that after RFA, CD3+ T cells, in particular CD4+, were decreased in metastatic cancer patients, while no change was observed in HCC patients.

An update in neoadjuvant chemotherapy in cervical cancer.

More than two decades have passed since neoadjuvant chemotherapy has been introduced in the clinical practice. After several pilot studies, randomized trials and meta-analysis have confirmed the validity of this therapeutic strategy and in particular of neoadjuvant chemotherapy followed by radical surgery. Several open questions still remain unanswered and in particular no standard drug regiment is unanimously accepted.
