Abstract PURPOSE Although tumor is known to exist beyond the contrast-enhancing margin, a lack of access pathological information enhancement has hindered study non-angiogenic characteristics and their effects on patient prognosis. This tested hypothesis that radio-pathomic maps developed using autopsy tissue samples can identify phenotypes relevant survival treatment outcomes. METHODS A datase...

OBJECTIVE To evaluate long-term visual outcome following chemoreduction. DESIGN Interventional case series evaluating 54 eyes of 40 children with retinoblastoma successfully treated with chemoreduction, consisting of a combination of intravenous carboplatin, etoposide phosphate, and vincristine sulfate plus focal therapy without external beam radiotherapy or enucleation. All patients were fol...

Introduction: Gastric cancer is a multifactorial disease and the fourth most common cancer in the world and the second cause of death from cancer. This study was designed and performed to investigate CDH1 and RUNX3 genes expression in healthy and tumor marginal tissue of people with gastric cancer. Methods: In this case-control study, 64 samples including 32 samples of gastric tumor tissue a...

Objective(s): Similar characteristics of molecular pathways between cellular reprogramming events and tumorigenesis have been accentuated in recent years. Reprogramming-related transcription factors, also known as Yamanaka factors (OCT4, SOX2, KLF4, and c-MYC), are also well-known oncogenes promoting cancer initiation, progression, and cellular transformation into cancer stem cells. Long non-co...

Porous silicon nanoneedles can map Cathepsin B activity across normal and tumor human esophageal mucosa. Assembling a peptide-based Cathepsin B cleavable sensor over a large array of nano-needles allows the discrimination of cancer cells from healthy ones in mixed culture. The same sensor applied to tissue can map Cathepsin B activity with high resolution across the tumor margin area of esophag...

Vascular disruption agents (VDA) cause occlusion of tumor vasculature, resulting in hypoxia-driven tumor cell necrosis. Tumor vascular disruption is a therapeutic strategy of great potential; however, VDAs currently under development display a narrow therapeutic margin, with cardiovascular toxicity posing a dose-limiting obstacle. Discovery of new VDAs, which display a wider therapeutic margin,...

Standard treatment for clinical stage I esophageal cancer with submucosal invasion (T1b) has been surgical resection. We conducted a Phase II trial to evaluate the efficacy and the safety of combined treatment of endoscopic mucosal resection (EMR) and chemoradiotherapy for clinical stage I (T1b) esophageal cancer. Patients diagnosed as having clinical stage I (T1b) esophageal cancer which is co...

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignant tumor of eccrine origin. Clinically, the carcinoma presents as a solitary, slow growing, and painless nodule. For this reason, this tumor is often considered to be a benign mass in the preoperative setting. The lesion is, however, malignant in nature and has a tendency for local recurrence and infrequent metastasis. Wide local exci...

PURPOSE The identification of colon cancer patients at high risk of local recurrence is necessary to improve the selection of patients for more tailored treatment protocols. The aim of this study was to develop a predictive model of local recurrence by assessing the independent predictive effect of 7 clinicopathologic features, 24 protein markers of tumor progression, and their multifeature com...

This multicenter prospective study ( Japanese Radiation Oncology Study Group: JROSG 05-5) aimed to evaluate the effectiveness of postoperative radiotherapy (PORT) in patients with ductal carcinoma in situ (DCIS) with an involved surgical margin or close margin widths of ≤1 mm or less. PORT consisted of whole-breast irradiation (50 Gy in 25 fractions) followed by boost irradiation (10 Gy in 5 fr...
