Malignant transformation of a mature teratoma in the duodenum: A case report.

Introduction: Mature teratomas of the duodenum are extremely rare, with only five cases reported in the English literature and none documented in Vietnam. Malignant transformation within a mature teratoma presents a challenging scenario for diagnosis and management, requiring a nuanced approach to treatment.

Presentation Of Case: We report the first documented case of malignant transformation in a duodenal mature teratoma in Vietnam.

Evaluation of a multimodal ctDNA-based assay for detection of aggressive cancers lacking standard screening tests.

Cancers lacking standard screening (LSS) options account for approximately 70% of cancer-related deaths due to late-stage diagnosis. Circulating tumor DNA (ctDNA) is a promising biomarker for multi-cancer early detection. We previously developed SPOT-MAS, a multimodal ctDNA-based assay analyzing methylation and fragmentomic profiles, effective in detecting common cancers (breast, colorectal, liver, lung and gastric).

Major Low Anterior Resection Syndrome (LARS) and Quality of Life in Patients With Low Rectal Cancer: A Preoperative Survey Using LARS Score and European Organisation for Research and Treatment of Cancer's 30-Item Core Quality of Life Questionnaire.

Background Rectal resection with total mesorectal excision is a difficult surgery with potential risks of complications. This study aims to assess the quality of life (QoL) of patients with low rectal cancer who have bowel function disorders equivalent to major low anterior resection syndrome (LARS) and its risk factors before treatment. Methods A descriptive cross-sectional study was conducted on 83 patients diagnosed with low rectal cancer who had not been treated.
