Objectives: We retrospectively examined the initial experience and learning curve after the introduction of thrombectomy with the combined technique using an aspiration catheter and a stent retriever as first-line attempt for acute ischemic stroke.
Methods: Consecutive patients undergoing thrombectomy for acute ischemic stroke at our institution between January 2020 and December 2022 were divided into 3 groups according to the year of thrombectomy. Patient characteristics and procedural, safety, and clinical outcomes were compared between the three year periods to determine predictors of favorable clinical outcome.
Background: Calcified cerebral embolism has been reported as a cause of acute cerebral infarction, but an aortogenic origin has rarely been identified as the embolic source. The authors describe a case of aortogenic calcified cerebral embolism in a patient with other embolic sources.
Observations: In a patient with cerebral infarction and atrial fibrillation, a white hard embolus was retrieved by mechanical thrombectomy.
Background: There is no established opinion regarding embolization of asymptomatic traumatic vertebral artery injuries that do not require cervical spine repair and fixation.
Case Description: A 78-year-old man fell backward from a height of about 1 m and was rushed to his previous hospital. He had a fracture of the left transverse process of the 6 cervical vertebra.
Pulmonary pleomorphic carcinoma (PPC) is well-known for its aggressive nature that is usually resistant to platinum-based chemotherapy. On the other hand, the efficacy of an immune checkpoint inhibitor-based regimen in PPC has been elucidated. PPCs harboring epidermal growth factor receptor (EGFR) mutations are extremely rare, and the efficacy of EGFR-tyrosine kinase inhibitors in PPC is limited compared to their efficacy in EGFR-mutated adenocarcinoma.

LCNECs containing other components are called 'combined LCNECs' and have no standard treatment. A 73-year-old male with a metastatic brain tumour from a combined LCNEC of the lung containing adenocarcinoma and sarcomatoid components was referred to our department.

Crizotinib is the first tyrosine kinase inhibitor (TKI) against -rearranged NSCLC. G2032R, a secondary resistant mutation, is observed in 41% of patients treated with crizotinib.

They cause malnutrition, performance status (PS) deterioration, and difficulty in the oral administration of antitumor drug tablets. A 78-year-old female patient with lung adenocarcinoma, harboring an epidermal growth factor receptor (EGFR)-sensitizing mutation, experienced dysphagia due to an esophageal stricture caused by retrotracheal lymph node metastases.

The bevacizumab-containing chemoimmunotherapy regimen is theoretically more effective than a non-bevacizumab-containing regimen via two mechanisms: a superior outcome of bevacizumab-containing chemothrerapy than the standard platinum doublet regimen, and the synergistic effect of bevacizumab with an immune checkpoint inhibitor (ICI). Bevacizumab effectively normalizes vascularization, especially when the vascular bed is damaged by previous treatment.
