Comparison of Prognostic Outcomes Between Repeat Liver Resection and Particle Therapy for Patients with Recurrent Hepatocellular Carcinoma.

Background: Particle therapy (PT) as an initial hepatocellular carcinoma (HCC) treatment has been reported to be effective; however, its efficacy for the treatment of recurrent HCC remains unclear.

Objective: This study aimed to evaluate the efficacy of PT compared with repeat liver resection for treating recurrent HCC after initial LR, with a focus on prognostic outcomes.

Methods: Between 2005 and 2019, 89 and 49 patients underwent repeat LR and PT for recurrent HCC after initial LR, respectively.

Usefulness of the Preoperative Images Supporting Mechanical Thrombectomy Based on Susceptibility-Weighted Image for Stroke.

Objective: This is a report on the usefulness of 3D fusion imaging with susceptibility-weighted imaging (SWI) as preoperative imaging for mechanical thrombectomy (MT) for acute ischemic stroke (AIS).

Case Presentations: Among 17 cases of patients who underwent MT in AIS between March 2021 and April 2022, 14 patients who underwent MRI with SWI (shortened SWI for stroke) and 3D T2-weighted sampling perfection with application-optimized contrasts using different flip angle evolution were targeted in the study. Three cases with motion artifacts due to body movement were excluded from the images.

Rare Anal Canal Cancer with Secondary Extramammary Paget's Disease (Pagetoid Spread) Complicated by Squamous Cell Carcinoma of the Skin.

A 91-year-old man had a node and erythema in the anal area resistant to treatment. A biopsy of the node in the anus showed atypical cells developing as Paget's disease, and staining revealed that the cells were CK7-positive, CK20-positive, and GCDFP15-negative. Therefore, tumor invasion with pagetoid spread (PS) from the anus to the skin was suspected, and the patient was referred to our department for a close examination and surgical treatment.
