Advances in cancer management have significantly improved survival in patients with cancers. Cardiovascular complications of cancer treatment are becoming significant competing causes of death in these patients. Radiotherapy is an indispensable component of cancer treatment, and irradiation of the heart and vasculature during cancer radiotherapy is now recognized as a new risk factor for cardiovascular diseases.

The standard treatment regimen for patients diagnosed with non-small cell lung cancer (NSCLC) with locally advanced stage III disease is concurrent chemoradiotherapy (CCRT). This study investigated the molecular effects of vinca alkaloid vinorelbine (VNR)-based CCRT. We reviewed the records of 68 patients with stage III NSCLC: 42 patients received VNR-based CCRT, and 26 were treated with radiation alone.

Nasopharyngeal carcinoma (NPC) is common in southern China, and radiotherapy remains the mainstay of treatment. A rare late complication of this treatment is the development of osteoradionecrosis (ORN), which seldom involves the cervical spine. We describe a 47-year-old female with undifferentiated carcinoma of the nasopharynx, stage II (T2N0M0), who had undergone radiotherapy 51 months prior, and complained of a twitching headache on neck flexion/extension.

Study Design: We evaluated the electrophysiological changes to the cauda equina after low-dose external irradiation in a postlaminotomy fibrosis model in rats.

Objective: To clarify the immediate and long-term electrophysiological responses of antifibrotic radiation therapy in a fibrosis model.

Summary Of Background Data: Low-dose perioperative radiation therapy inhibits scar formation.

Purpose: The genetic basis for gastrointestinal and ampullary carcinomas remains uncertain. This study was performed to pinpoint novel chromosomal region involved in the tumorigenesis of gastrointestinal tract.

Methods: We screened the allelic status on 16 chromosomal arms in a patient with synchronous ampullary carcinoma and gastric cancer, but who had no family history of familial cancer syndrome.

Objectives: To perform a global loss of heterozygosity (LOH) analysis on a cohort of urothelial carcinoma to investigate the clinical implication of specific chromosomal loss. Allelic deletions detected as LOH have been used to study the markers for carcinogenesis.

Methods: We examined the allelic loss on 14 chromosomal regions in a total of 71 cases of urothelial carcinoma.
