Article Abstract
Background: This study was done to evaluate the prognostic factors that may affect the survival of patients with recurrent hepatic metastasis after curative resection of gastric cancer.
Methods: We reviewed the medical records of 73 patients with recurrent hepatic metastasis after surgical treatment of gastric cancer from January 1995 to December 2005. Prognostic factors were classified into three groups: primary tumor factors, recurrent hepatic factors, and treatment factors. The prognostic values of these factors were assessed using univariate and multivariate analyses by the log-rank test in the Kaplan-Meier method and Cox's proportional hazard model.
Results: The overall median survival rate of the 73 study patients was 20.0 months [95% confidence interval (CI) 15.4-24.6 months]. The median survival rate after diagnosis of recurrent hepatic metastasis was 5 months (95% CI 3.5-6.5 months). Univariate analysis showed that the favorable prognostic factors were stage I and II among the primary tumor factors, no extrahepatic metastasis and unilobar distribution among the recurrent hepatic factors, and radiofrequency ablation (RFA) +/- chemotherapy among the treatment factors when operative treatment had been excluded. The independent favorable prognostic factors revealed by the multivariate analysis were no extrahepatic metastasis and RFA +/- chemotherapy. The median survival rate of patients who had two favorable prognostic factors was 27 months (95% CI 0-66.38 months).
Conclusions: Improvement in the survival rate can be expected with RFA +/- chemotherapy for patients with recurrent gastric cancer in the liver without extrahepatic metastasis.

Mediastinal masses often present acutely as medical emergencies, necessitating prompt and accurate diagnosis. Imaging-guided fine needle aspiration cytology (FNAC) plays a pivotal role in rapidly identifying rare mediastinal tumours and differentiating them from other potential aetiologies, enabling timely intervention. Primary mediastinal germ cell tumours (PMGCTs) constitute approximately 15% of adult mediastinal neoplasms.

Plantar melanomas present unique diagnostic and surgical challenges owing to substantial regional variations in skin thickness. Although the Breslow thickness remains the primary criterion for staging and surgical excision, its application on plantar melanoma is complicated by the inherent thickness of the glabrous plantar epidermis, which may lead to tumor depth overestimation. Accurate assessment of plantar skin thickness is essential for optimizing staging accuracy and refining surgical margins.

Unlabelled: Leptomeningeal metastasis (LM) is a severe complication of solid malignancies, including lung adenocarcinoma, characterized by poor prognosis and diagnostic challenges. This study assesses whether curvilinear peri-brainstem hyperintense signals on MRI are a characteristic feature of LM in lung adenocarcinoma patients.
Methods: This retrospective study analyzed data from multiple centers, encompassing lung adenocarcinoma patients with peri-brainstem curvilinear hyperintense signals on MRI between January 2016 and March 2022.

Objectives: The risk of major venous thromboembolism (VTE) among patients with COVID-19 is high but varies with disease severity. Estimate the incidence of lower extremity deep venous thrombosis (DVT) in critically ill hospitalized patients with COVID-19, validate the Wells score for DVT diagnosis, and determine patients' prognosis.
Methods: This was an observational follow-up study in the context of the diagnosis and prognosis of DVT.

Paratesticular rhabdomyosarcoma (RMS) is a rare pediatric malignancy often misdiagnosed as benign conditions like epididymitis. We report a 4-year-old boy with paratesticular RMS and retroperitoneal metastasis, initially mistaken for epididymitis. The diagnostic delay resulted in disease progression, necessitating radical inguinal orchiectomy, hemiscrotectomy, and complete multimodal therapy.
