Altered Dynamic Neural Activity in the Default Mode Network in Lung Cancer Patients After Chemotherapy.

CONCLUSIONS The current study indicated that patients with lung cancer after CTx had decreased dynamic brain activity in the DMN region, and the DMN is vulnerable when patients undergoing CTx. PMID: 32069270 [PubMed - in process]

In this study, we reported the case of a 74-year-old Japanese woman who developed PLE after partial remission of small cell lung cancer (SCLC) by first-line systemic chemotherapy. Brain magnetic resonance imaging showed no metastatic tumor or cerebrovascular disease. Anti-glutamic acid decarboxylase (GAD) and anti-amphiphysin antibodies were detected in her serum. She was diagnosed as having PLE related to the recurrence of SCLC and received high-dose glucocorticoid, and sequentially systemic chemotherapy with amrubicin. Unfortunately, these treatments did not improve her disease progression and she died 4 months later. Al...

Conclusions The recent, first randomized clinical trial demonstrated overall and progression free survival benefits after SBRT to oligometastatic disease which supports prior retrospective case series (6). The spine is a common site of metastatic bone disease, and as high quality data continue to mature, along with completion of additional randomized clinical trials, it is expected that utility of SBRT to the spine will increase in the future. Spine SBRT is unique due to the requirement of sharp dose falloff to prevent serious neurologic morbidity. With recent advances in radiotherapy planning, robotic patient positionin...

Abstract A 66-year-old Japanese male patient was referred to Saitama Medical University International Medical Center for treatment of bladder cancer (clinical stage T2 or higher without metastasis), and underwent radical cystectomy with pelvic lymphadenectomy. The histopathological diagnosis was high-grade urothelial carcinoma (pathological stage T2bN2, ly1, v0) and 2 cycles of adjuvant systemic chemotherapy (gemcitabine plus cisplatin) were administered. At 15 months after the operation, mediastinal and lung hilar lymph nodes and multiple bone metastases were identified on computed tomography imaging. After 3 cyc...

Rationale: The efficacy of direct oral anticoagulants (DOACs) in the treatment and prophylaxis of cancer-related venous thromboembolism (VTE) is reportedly similar to that of heparin. However, the effect of DOACs on the prophylaxis of cancer-related arterial thromboembolism (ATE) remains unclear. To our knowledge, we present the 1st case where cerebral ATE was encountered during edoxaban administration for VTE in a patient with lung adenocarcinoma. Patient concerns: In March 2017, a 63-year-old female was diagnosed with lung adenocarcinoma (cT2aN3M1b stage IVa) along with having asymptomatic VTE; thus, 60 mg/day edo...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

This study aimed to investigate the intrinsic functional connectivity (FC) pattern within the default mode network (DMN) and its associations with cognitive impairment in patients with lung cancer revealed by resting-state functional magnetic resonance imaging (fMRI). Resting-state fMRI scans were acquired from 21 post-chemotherapy and 27 non-chemotherapy lung cancer patients and 30 healthy controls. All groups were age, gender and education-matched. The posterior cingulate cortex (PCC) was chosen as the seed region to detect the FC patterns and then determine whether these changes were related with specific cognitive perf...

Authors: Ashinuma H, Shingyoji M, Hasegawa Y, Yokoi S, Yoshida Y Abstract The mechanisms underlying anaplastic lymphoma kinase (ALK) resistance have not been well investigated in clinical practice. We herein report the case of a lung cancer patient with carcinomatous meningitis who had an ALK I1171T resistance mutation revealed by direct DNA sequencing of the cerebrospinal fluid after treatment with cytotoxic chemotherapy, crizotinib, and alectinib. I1171T is considered to be sensitive to ceritinib. Although ceritinib was not effective initially, we chose ceritinib again after whole-brain radiotherapy and ventricul...

Radiation has 2 evidence-based roles in extensive-stage small cell lung cancer: as prophylactic cranial irradiation (PCI) and as thoracic consolidation. The most recent randomized trial comparing PCI with observation for extensive-stage small cell lung cancer used more rigorous imaging than prior studies, with magnetic resonance imaging (MRI) restaging of the brain after chemotherapy and surveillance brain MRI for 2  years (1). The study terminated for futility after the first interim analysis, with no suggestion of benefit to PCI (2).

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...
