PURPOSE Prostate tumor volume calculated after surgery using pathologic tissue has been shown to be an independent risk factor for biochemical recurrence. Nonetheless, prostate size varies among individuals, regardless of the presence or absence of cancer. We assumed to be lower margin positive rate in the surgical operation, when the prostate volume is larger and the tumor lesion is same. Thus...

OBJECTIVES/HYPOTHESIS Surgical treatment of inverted papilloma (IP) of the sphenoid sinus is complicated by close proximity to vital structures of the skull base. Identifying the site of tumor attachment and achieving complete removal can be challenging compared to IP at other sites. The objective of this study is to illustrate the clinical presentation, management, and risk factors for tumor r...

Although many tumors regress in response to neoadjuvant chemotherapy, residual tumor cells are detected in most cancer patients post-treatment. These residual tumor cells are thought to remain dormant for years before resuming growth, resulting in tumor recurrence. Considering that recurrent tumors are most often responsible for patient mortality, there exists an urgent need to study signaling ...

BACKGROUND Despite increasingly radical surgery for esophageal carcinoma, many patients still develop tumor recurrence after operation. This study was designed to analyze the clinical and pathologic influencing factors of early recurrence in patients with histological node-negative (pN0 stage) esophageal squamous cell carcinoma (ESCC) after radical esophagectomy. METHODS A retrospective study...

Introduction: Breast cancer is the most common cancer and the leading cause of cancer-related death in women. Clinicopathological variables are important factors in deciding on breast cancer treatment. This study evaluated the association between the recurrence score generated by the Oncotype DX® 21-gene assay and classic clinicopathological variables. Methods: A single-institution retrospect...

INTRODUCTION Radionecrosis (post-radiotherapy laryngeal submucosal inflammation and necrosis) is a complication of (chemo) radiotherapy for hypopharyngeal cancer that is difficult to differentiate from tumor recurrence. CASE PRESENTATION A 67-year-old Japanese man presented with a condition extremely difficult to diagnose differentially as radionecrosis or tumor recurrence after radiotherapy ...

BACKGROUND Liver transplantation (LT) is the treatment of choice for hepatocellular carcinoma (HCC). The aim of this study was to investigate the recurrence rate of HCC after LT and prognostic factors for recurrence by comparing LT with non-transplanted resection. METHODS The participants were 338 patients who underwent LT between 1996 and 2012 at Seoul National University Hospital (LT group)...

Background:   Primary bone lymphoma or non-Hodgkin lymphoma of bone is a rare disease. There are only a few case series of stage IE of this condition in medical literature. The aim of this study is to determine the rate of survival   for stage IE after combined modality treatment, the rate of local recurrence, and the results of limb salvage in cases   of local recurrence.     Methods:   We col...
