inflammatory myofibroblastic tumor (imt) is an aggressive benign mass that may arise from various tissues and organs with a great variability of histological and clinical appearances. due to variable and nonspecific imaging findings, diagnosis of imt is not obtained before surgery. the aim of this paper is to present ct and mri findings during four-year follow-up of complete, spontaneous regres...

conclusions overall, cancer incidence rates had increased in both sexes. many factors were responsible, such as changes in lifestyle, environmental factors, increased life expectancy, improvements in the registration systems, and declining mortality rates due to early detection and treatment. the results of this study provided useful information for the prediction of changes in the incidence an...

Preoperative radiotherapy is standard procedure in rectal cancer treatment protocols. Experience and analysis of clinical and laboratory features of the results of this procedure have established that the response to radiotherapy, in order to reduce the volume of tumor and adenopathies of stations I and II is highly variable, from complete disappearance of the tumor mass, to the lack of respons...

shown that regression of the Jensen rat sarcoma can be achieved when the neoplasm itself is shield ed by lead, leaving only the surrounding tumor bed exposed to radiation. The experiments of Sugiura (13) and of Vermund et al. (14), which showed that the growth of tumor transplants was inhibited in pre-irradiated sites, also support the concept that radiation produces tumor-inhibitory agencies i...

BACKGROUND Limited data are available for advanced colorectal neoplasm in asymptomatic individuals aged 40-49 years. We aimed to identify risk factors and develop a simple prediction model for advanced colorectal neoplasm in these persons. METHODS Clinical data were collected on 2781 asymptomatic subjects aged 40-49 years who underwent colonoscopy for routine health examination. Subjects were...

OBJECTIVE We prospectively assessed the age- and sex-specific incidence and relative risk of malignant neoplasm of the pancreas in Taiwan's diabetic population. RESEARCH DESIGN AND METHODS A total of 615,532 diabetic patients and 614,871 age- and sex-matched control subjects were linked to inpatient claims (2000-2006) to identify the admissions for malignant neoplasm of the pancreas (ICD-9: 1...

BACKGROUND Malignant neoplasm of the pancreas has become one of the leading causes of death from malignant neoplasm in Japan (the 5th in 2003). Although smoking is believed to be a risk factor, other risk factors remain unclear. Mortality from malignant neoplasm of the pancreas tends to be higher in northern Japan and in northern European countries. A recent study reported that standardized mor...

BACKGROUND Nosocomial infection (NI) causes prolonged hospital stays, increased healthcare costs, and higher mortality among patients with hematological malignancies (HM). However, few studies have compared the incidence of NI according to the HM lineage. OBJECTIVE To compare the incidence of NI according to the type of HM lineage, and identify the risk factors for NI. METHODS This prospect...

Erlotinib is an inhibitor of the tyrosine-kinase domain of the epidermal growth factor receptor-1 (EGFR). This drug is used to treat some solid cancers, particularly advanced non-small-cell lung carcinoma. Similar to other EGFR inhibitors, erlotinib is responsible for a series of skin adverse reactions, particularly acneiform lesions. We described the incidental effect of erlotinib on actinic k...
