The pathophysiology of hypertension and cancer are intertwined. Hypertension has been associated with an increased likelihood of developing certain cancers and with higher cancer-related mortality. Moreover, various anticancer therapies have been reported to cause new elevated blood pressure or worsening of previously well-controlled hypertension. Hypertension is a well-established risk factor for the development of cardiovascular disease, which is rapidly emerging as one of the leading causes of death and disability in patients with cancer. In this review, we discuss the relationship between hypertension and cancer and the role that hypertension plays in exacerbating the risk for anthracycline- and trastuzumab-induced cardiomyopathy. We then review the common cancer therapies that have been associated with the development of hypertension, including VEGF inhibitors, small molecule tyrosine kinase inhibitors, proteasome inhibitors, alkylating agents, glucocorticoids, and immunosuppressive agents. When available, we present strategies for blood pressure management for each drug class. Finally, we discuss blood pressure goals for patients with cancer and strategies for assessment and management. It is of utmost importance to maintain optimal blood pressure control in the oncologic patient to reduce the risk of chemotherapy-induced cardiotoxicity and to decrease the risk of long-term cardiovascular disease.
Leptomeningeal metastasis (LM), also known as leptomeningeal carcinomatosis (LC), is a devastating complication of metastatic cancer that occurs when neoplastic cells invade the meningeal space. Diagnosis of LM remains challenging given the heterogeneous signs and symptoms at presentation and requires thorough neurological examination, cerebrospinal fluid (CSF) analysis, and magnetic resonance imaging (MRI) of the brain and spine with gadolinium. Detecting neoplastic cells in the cerebrospinal fluid is the gold standard for diagnosing leptomeningeal metastases; however, it has low sensitivity and may require multiple CSF samples. New emerging technologies, such as liquid biopsy of CSF, have increased sensitivity and specificity for detecting circulating tumor cells (CTC) in CSF. The management of LM in NSCLC patients requires an individualized multidisciplinary approach. Treatment options include surgery for ventricular shunt placement, radiation therapy to bulky or symptomatic disease sites, systemic or intrathecal chemotherapy, molecularly targeted agents, and, more recently, immunotherapy. Targeting actionable mutations in LM from NSCLC, such as epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) or anaplastic lymphoma kinase (ALK) gene rearrangement inhibitors, have shown encouraging results in terms of disease control and survival. Although there is limited data regarding the use of immunotherapy in LM, immunotherapy has produced promising results in several case reports. In this review, we focused on the epidemiology, pathophysiology, clinical presentation, diagnosis, and current treatment strategies, with a special emphasis on novel agents, including targeted therapies and immunotherapy of LM in patients with NSCLC.
Introduction Bortezomib is a proteasome inhibitor used in the treatment of multiple myeloma, Waldenström’s macroglobulinemia, mantle cell lymphoma. The most reported adverse effects include fatigue, thrombocytopenia, gastrointestinal symptoms, and peripheral neuropathy, which mostly manifests as sensory neuropathic symptoms. We present a case of a patient who experienced motor neuropathy after initiating treatment with bortezomib. Case report An 87-year-old male was diagnosed with multiple myeloma and started on treatment with bortezomib, dexamethasone, and lenalidomide (VRd). After five cycles of therapy, he developed lower extremity weakness, which was severely debilitating, affecting his ability to walk, and this prompted his visit to the emergency department. Management and outcome The patient was admitted for further workup and underwent electromyography, which was consistent with demyelinating polyneuropathy with active denervation. His symptoms were attributed to bortezomib, and his VRd regimen was held. His symptoms failed to improve despite discontinuation of bortezomib. He then received steroids and intravenous immunoglobulin (IViG) with a gradual resolution of his symptoms. He was thereafter restarted on only lenalidomide and dexamethasone with no recurrence of his neuropathy. Discussion Clinicians need to be aware of the likely risk for motor neuropathy associated with bortezomib. Risk factors like older age and pre-existing neuropathy can predispose patients to this adverse effect, and clinicians should monitor for this toxicity and facilitate dose reduction or discontinuation of therapy if warranted. Sometimes, patients may also need further treatment with steroids or IVIG.
Oxaliplatin, a platinum-based chemotherapy agent, is commonly used in the treatment of various malignancies. Common adverse effects involve neurological, hematological, gastrointestinal system, and hypersensitivity, and rarely ocular changes have also been reported. We describe the case of a 71-year-old male, who developed reversible ocular toxicity after receiving oxaliplatin for treatment for pancreatic cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
