Cognitive Impairment Associated with Cancer: A Brief Review

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but not well understood due, in part, to marked differences in the research methods and definitions used for evaluating cognitive functioning in these patients. Most studies have identified attention, memory, and information processing as the most frequent cognitive domains impacted by cancer and cancer-related treatments, but further research clearly is needed. Recent efforts have been made to develop common definitions to define cognitive impairment in cancer patients and to suggest guidelines for the most appropriate cognitive tests to be used. Cognitive function has increasingly been recognized as a requisite therapeutic target in many diseases, including cancer. The extent of cognitive impairment that is observed in patients with cancer and those in remission make cognitive functioning a particularly important target for clinical trials and clinical practi...

Authors: Ono Y, Yoshikura N, Takekoshi A, Ohe N, Hayashi H, Yamada M, Hayashi Y, Kimura A, Shimohata T Abstract A 57-year-old woman with amyotrophic lateral sclerosis (ALS) receiving mechanical ventilation developed intractable right temporal headache. She was diagnosed with brain abscess secondary to chronic suppurative otitis media. In this case, the otitis media was caused by nasopharyngeal reflux associated with eustachian tube muscle weakness and a supine position. In addition, ALS patients under mechanical ventilation have a limited ability to convey their pain. Their complaints are often overlooked because m...

She had a pituitary adenoma, but the follicle-stimulating hormone (FSH) concentration was within the normal range. The patient complained of neck pain and palpitations during the disease course, and laboratory results revealed thyrotoxicosis and a systemic inflammatory response with negative findings for anti-thyroid stimulating hormone (TSH) receptor antibody and positive findings for anti-thyroglobulin and anti-thyroid peroxidase...

Authors: Higashihara T, Okada A, Nakamura Y, Saigusa H, Homma S, Matsumura M, Kusano T, Shimizu A, Takano H Abstract We performed a renal biopsy for nephrotic syndrome in a patient with squamous cell lung carcinoma, which can worsen the prognosis. Chemoradiation therapy was effective for the cancer and proteinuria; we thus inferred that the nephrotic syndrome had been closely associated with the carcinoma. A pathological analysis of the kidney showed monoclonality for λ chain, satisfying the diagnostic criteria of proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID); however, con...

Ten days after admission, fluid-attenuated inversion-recovery magnetic resonance imaging (MRI) revealed hyperintense areas around the bilateral hypothalamus, which were not present on MRI at admission. The orexin level, which is decreased in idiopathic narcolepsy, was slightly decreased in her cerebrospinal fluid. Immunosuppressive treatment and methylphenidate markedly improved her somnolence. This case sho...

ConclusionsThe results of this study showed that lung volume changes were not a cause for concern in breast cancer patients. There are three reasons to support this conclusion. Lung volume changes and percentage reductions in LVP for each Gy increase of MLD and each percentage increase of V20 in each lobe were small; patients were asymptomatic during the follow-up period; and LVP showed partial improvements after 6 months.

ConclusionsExternal beam APBI results in excellent long-term disease control. Good to excellent cosmetic outcomes are achieved in most patients, although increasing dose per fraction and greater percentage of irradiated breast were predictive of adverse posttreatment cosmetic outcomes. Select patients in “cautionary” and “unsuitable” consensus groupings do not appear to have inferior outcomes.

AbstractThe use of conventional chemotherapy in the treatment of cancer has been restricted by the lack of cell specificity, which causes toxicity regarding healthy cells resulting in limiting side effects responsible for low therapeutic efficiency. To overcome these drawbacks, the design of prodrugs has evolved and improved by covalently linking the drug through a degradable spacer. The use of these prodrugs as drug delivery systems, which are able to inactivate the drug during its biodistribution to specifically deliver the drug to its target, is an important breakthrough in cancer therapy. This strategy consisting in th...

ConclusionsThe exposure –response analysis suggested that intermittent 7-day veliparib 120 mg BID dosing in a 21-day cycle provided additional efficacy without meaningfully impacting the safety and tolerability when co-administered with carboplatin and paclitaxel in patients with BRCA-deficient breast cancer. A higher d ose of veliparib is unlikely to provide greater benefit in this combination in patients with BRCA-deficient recurrent or metastatic breast cancer.

AbstractThioredoxin (Trx), thioredoxin reductase (TrxR), and NADPH are key members of the Trx system that is involved in redox regulation and antioxidant defense. In recent years, several researchers have provided information about the roles of the Trx system in cancer development and progression. These reports indicated that many tumor cells express high levels of Trx and TrxR, which can be responsible for drug resistance in tumorigenesis. Inhibition of the Trx system may thus contribute to cancer therapy and improving chemotherapeutic agents. There are now a number of effective natural and synthetic inhibitors with chemo...
