Postoperative adjuvant immunotherapy for high-risk hepatocellular carcinoma patients.

Background And Aim: Standardized approach to postoperative adjuvant therapy for hepatocellular carcinoma (HCC) remains elusive. This study endeavors to examine the effects of postoperative PD-1 adjuvant therapy on the short-term and long-term prognosis of patients at a heightened risk of post-surgical recurrence.

Methods: The data of HCC patients who underwent hepatectomy at our center from June 2018 to March 2023 were collected from the hospital database.

CK5/6-positive, P63-positive lymphoepithelioma-like hepatocellular carcinoma: A case report and literature review.

Background: Lymphoepithelioma-like carcinoma (LELC), a rare and unique variant of liver cancer, can be divided into lymphoepithelioma-like hepatocellular carcinoma and lymphoepithelioma-like intrahepatic cholangiocarcinoma. Dense lymphocytic infiltration is its characteristic pathological feature. In recent years, the number of reported cases of this type has increased each year.

High-power tunable dual-wavelength diode laser with a composite external cavity.

A high-power tunable dual-wavelength composite external cavity architecture obtained by means of a holographic grating and a volume Bragg grating is proposed and demonstrated. The tunable frequency difference of the dual-wavelength output is from 0.41 THz to 3.
