Vaccine prevalence exceeded 70% in those ≥65 years and was only 27.8% in survivors 19–44 years. Selleck ITF2357 increasing age, being without a spouse,

having poor self-rated health, and having a shorter duration since cancer diagnosis were significant predictors of vaccination status among cancer survivors <65 years. Shorter duration since cancer diagnosis was the only factor associated with vaccination status in cancer survivors ≥65 years. Conclusion: Influenza vaccine coverage remains much lower than recommended among cancer survivors, particularly in younger age groups. These results may help better target preventive health care efforts to increase vaccination prevalence and reduce health risks for cancer survivors.

However, there was no definite guideline for the management and the follow up

period of small subepithelial tumor (SET) in upper gastrointestinal tract (GIT). Therefore, we evaluated the natural course of SELs using EUS and the characteristics of growing SETs. Methods: From October 2004 to June 2014, we

retrospectively investigated the size changes, echogenicity, echogenic foci, and origin layer of SETs less than 30 mm in EUS findings. The significant growth of SET defined as increasing more than 25% of the longest diameter in the last EUS finding comparing the initial study. Results: A total of 131 upper GIT SETs in 122 patients were examined two more times using EUS. The median follow up interval for SETs was 25 months (range, 3 to 124 months). The location of SETs was 31 (23.7%), 93 (71.0%), Thymidylate synthase 7 (5.3%) in esophagus, stomach, and duodenum, respectively. The majority of SETs were located in the 4th layer (90/131, 68.7%), and 117 SETs (89.3%) had hypogenicity and 107 SETs (81.1%) had homogenecity. Among 131 SETs, 28 SETs (21.4%) showed significant increase in follow up EUS. However, initial size, echogenicity, presence of echogenic foci, layer of origin, and marginal regularity were not significantly associated with the growth of the tumor. Conclusion: Although there were no significant relative factors about the SETs growth, however, about one fifth of the SETs showed the size changes. Therefore, regular observation of SETs by using EUS might be needed. Key Word(s): 1. subepithelial lesions; 2. endoscopic ultrasound; 3.
