Primary squamous cell carcinoma of the liver is rare. It has a high malignancy rate and poor prognosis, and survival is typically no longer than one year. The pathogenesis of the disease is unclear, but is generally considered to be correlated with the long-term inflammation or metaplasia of biliary epithelial cells and congenital cyst of the liver. The current viewpoint is that surgical resection of the tumor, preoperative or postoperative subsidiary chemoembolization, radiotherapy and generalized chemotherapy may extend a patient's survival. In the present case study, a patient suffered from biliary calculosis for over 20 years. We theorized that the mechanism of carcinomatous change was correlated with the persistent stimulation of chronic biliary infection induced by calculus of the intrahepatic duct. However, the transformation mechanism from cholangiocellular carcinoma to squamous carcinoma is undetermined and further studies are needed.

Introduction: Stage IV non-small cell lung carcinoma (NSCLC) with oligometastases is potentially curable by radical treatment. This study aimed to evaluate the efficacy and safety of chemoradiotherapy (CRT) for thoracic disease, including the primary lesion and lymph node metastases, combined with local consolidative therapy (LCT) for oligometastases.
Methods: This was a multicenter Phase II trial for patients with Stage IV NSCLC with oligometastases for whom CRT for thoracic disease was feasible.

The most common complication associated with selective neck dissection is spinal accessory nerve dysfunction and shoulder disability, which result from level IIb dissection. The main objective of this study was to evaluate the incidence of level IIb lymph node metastasis in clinically node-negative (cN0) oral squamous cell carcinoma (OSCC) patients. Patients presenting with cN0 OSCC between November 2012 and November 2023 were included retrospectively.

Background: In the context of transoral robotic surgery (TORS) for oropharyngeal squamous carcinoma (OPSCC), preoperative imaging and intraoperative visualization plays a pivotal role in optimizing resection margins. Prior work has demonstrated the ability of transoral ultrasound (US) in identifying OPSCC margins and vascular structures. This study evaluates the effectiveness of transcervical ultrasound (TUS), as well as other preoperative imaging modalities, in evaluating OPSCC volumes and compares this to post TORS pathological OPSCC volumes.

Methods: This retrospective, population-based cohort study analyzed 1,172 patients diagnosed with SCCC from January 1, 1975, through December 31, 2016. Data were extracted from the US Surveillance, Epidemiology, and End Results database.
