Immunotherapy

The next decade in cancer therapy will be marked by the expansion of immunotherapies, namely immune checkpoint inhibitors. The increasing number and combination of checkpoint inhibitors and the variety of their mechanisms of action and indications will most likely multiply the side effects associated with these therapies and make their management more complicated and diversified. Given the growing rate of approval of different checkpoint inhibitors in different cancers in multiple settings, a review summarizing the major side effects of the new agents in use today and their management seems to be appropriate. Highlighting these adverse events and their management in a single review might help the daily practice of the physicians and consequently contribute the patient's safety and quality of life.

Immune checkpoint inhibitors have been identified as breakthrough treatment in melanoma given its dramatic response to PD-1/PD-L1 blockade. This is likely to extend to many other cancers as hundreds of clinical trials are being conducted or proposed using this exciting modality of therapy in a variety of malignancies. While immune checkpoint inhibitors have been extensively studied in melanoma and more recently in lung cancer, little is known regarding immune checkpoint blockade in other cancers. This review will focus on the tumor immune microenvironment, the expression of PD-1/PD-L1 and the effect of immune modulation using PD-1 or PD-L1 inhibitors in patients with head and neck, prostate, urothelial, renal, breast, gastrointestinal and lung cancers.

Review
Role of inotuzumab ozogamicin in the treatment of relapsed/refractory acute lymphoblastic leukemia.
Inotuzumab ozogamicin is a humanized anti-CD22 monoclonal antibody bound to a toxic natural calicheamicin, which is under investigation for the treatment of relapsed/refractory acute lymphoblastic leukemia. CD22 is commonly expressed in 90-100% of malignant mature B-lymphocyte lineage. ⋯ Inotuzumab is well-tolerated with the exception of veno-occlusive disease. Overall inotuzumab ozogamicin is potentially an encouraging and promising therapy for patients.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic immune-mediated neuropathy: it is clinically heterogeneous (relapsing-remitting form, chronic progressive form, monophasic form or CIDP having a Guillain-Barré syndrome-like onset), but potentially treatable. Although its pathophysiology remains largely unknown, CIDP is considered an immune-mediated neuropathy. ⋯ However, these therapies remain unsatisfactory for many patients, so numerous other immunotherapeutic strategies have been evaluated, based on their immunosuppressant or immunomodulatory potency. We have performed a large review of the literature about treatment in CIDP, with a special emphasis on novel and alternative immunotherapeutic strategies.
