Cytokines regulate both the innate and adaptive immune responses to cancer. Although antitumor activity has been seen for several cytokines in preclinical models, they have had limited success as single therapeutic agents in clinical trials of cancer immunotherapy. However, the possible combinations of cytokines with other immune therapeutics and the advancement in genetic engineering, synthetic biology and cellular and immune therapy has led to the revival of interest in cytokines as anticancer agents. This article will review several immunostimulatory cytokines with anticancer activity, focusing on the those that have been studied in treatment of lymphoma and highlighting recent advances of potential clinical relevance.

Drug-induced thrombotic microangiopathies (DTMAs) are increasingly being recognized as an important category of thrombotic microangiopathies (TMAs). Cancer therapeutic agents including proteasome inhibitors (PIs) are among the most common medications reported to cause DTMA. PIs could cause DTMA either by an immune mechanism or dose-dependent/cumulative toxicity. Eleven cases of DTMA have been reported with bortezomib and carfilzomib. To the best of our knowledge, only one case of DTMA has been reported with ixazomib due to an immune-mediated mechanism. Here, we report the first case of ixazomib-induced DTMA due to cumulative toxicity rather than immune-mediated mechanism. In this article, we discuss the precipitating factors for cumulative toxicity of ixazomib, resulting in DTMA, diagnostic workup, and management of DTMA. We also discuss clinical reasoning based analysis of DTMA versus cancer-associated TMA as well as DTMA versus cyclic thrombocytopenia seen in PI use.

Patient: Male, 62 Final Diagnosis: Pituitary metastasis of small cell lung cancer Symptoms: Blurred vision • weakness Medication: — Clinical Procedure: — Specialty: Oncology Objective: Unusual clinical course Background: Pituitary gland metastasis is rarely the initial presentation of metastatic cancer. Most cases of pituitary gland metastasis are asymptomatic with diabetes insipidus being the most common symptomatic presentation. It can rarely present with symptoms of hormone underproduction such as secondary adrenal insufficiency. Although pituitary gland metastasis is rare, it is underestimated, as it is commonly misdiagnosed with pituitary gland adenoma due to the lack of clear radiological criteria differentiating between both. Case Report: We present a case of a 62-year-old male who presented with weakness, blurry vision, and persistent hypoglycemia despite intravenous dextrose infusion and having discontinued taking his diabetes medications. Chest x-ray showed a left hilar mass, while computed tomography scan demonstrated a left superior hilar mass and hilar lymphadenopathy with bilateral adrenal nodules and a T6 vertebral lesion suspicious for metastasis. Further workup showed secondary adrenal insufficiency with a low adrenocorticotropic hormone (ACTH) level. Vertebral biopsy was performed and confirmed the diagnosis of small cell carcinoma of the lung. This was followed by a brain magnetic resonance imaging (MRI), which showed multiple metastatic lesions with an enhancing mass involving the right clivus, sella, and suprasellar cistern with mass effect on the optic chiasm and involvement of the cavernous sinus supporting the diagnosis of pituitary gland metastasis of small cell lung cancer. The patient received brain radiation, and repeated MRI showed regression of the previous MRI findings. Conclusions: Secondary adrenal insufficiency is an unusual presentation of pituitary gland metastasis. Physicians should take into consideration both radiological findings and presentation to differentiate between pituitary gland metastasis and pituitary adenoma.

Prognosis for patients with refractory/relapsed (R/R) diffuse large B-cell lymphoma (DLBCL) is poor. Immune-based therapeutic treatments such as CD19 Chimeric Antigen Receptor (CAR) T cell therapies have dramatically changed the treatment landscape for R/R DLBCL leading to durable remissions in ~ 50% of patients. However, there remains an unmet need for developing novel therapies to improve clinical outcomes of patients not responding or relapsing after CAR T cell therapies. Lack of suitable immunotherapeutic targets and disease heterogeneity represent the foremost challenges in this emerging field. In this review, we discuss the recently approved and emerging novel immunotherapies for patients with R/R DLBCL in the post-CAR T era and the cell surface targets currently used.
