Multiple primary neoplasms are defined as multiple occurrences of malignant neoplasms of differing histological origin in the same individual. The present study describes the case of a 46-year-old male who suffered from two synchronous primary malignant neoplasms, an osteoclastoma of the left femoral trochanter and an anaplastic astrocytoma of the the Sylvian fissure area in the brain. At the 6...

BACKGROUND AND PURPOSE Developmental venous anomalies are considered variants of venous development that, in and of themselves, are of little clinical import. A possible association between intrinsic brain tumors and developmental venous anomalies has been suggested, but a rigorous investigation has not been performed. The aim of this study was to assess any association between developmental ve...

Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...

When treating childhood acute lymphoblastic leukemia (ALL), secondary neoplasms are a significant long term problem. Radiation is generally accepted to be a major cause of the development of secondary neoplasms. Following treatment for ALL, a variety of secondary tumors, including brain tumors, hematologic malignancies, sarcomas, thyroid cancers, and skin cancers have been reported. However, ol...

Brain tumors are rare neoplasms, however, they represent the second commonest cancer in childhood (the first being hemato-lymphoid neoplasms) and correspond to the main solid tumor in the pediatric context (ages 0-19 years) [1]. In this setting, gliomas, and particularly astrocytomas are the leading group. Pilocytic astrocytoma (PA) is the commonest brain tumor in the ages 5-14 years and the se...

PURPOSES To describe the visual manifestations of brain neoplasms, and to analyze the effect of tumor control on these. METHODS This is a descriptive retrospective study, which includes patients under 14 years of age, suffering from different brain neoplasms in our hospital between 1996 and 2005 inclusive. RESULTS In the group of patients with low visual acuity, 44% had organic amblyopias. ...

The relationship between chronic lymphocytic leukaemia (CLL) and primary malignant neoplasms was evaluated using data from the Hematology Division in Beilinson Medical Center and the Israel Cancer Registry. The study population consisted of 81 patients diagnosed between 1962 and 1984. A total of 16 patients were found to have 21 malignant neoplasms in addition to their CLL. Excluding patients w...

Case-control study. Amer. J. Epid., 1970, 97: 467-485.—This retrospective study was designed to elucidate selected epidemiologic variables possibly related to central nervous system (CNS) neoplasms.

Neoplasms of the brain are often overlooked in resource-limited countries. Our literature search via AJOL and PubMed demonstrated that brain tumor research is still a rarity in these regions. We highlight the current status, importance, challenges, and methods of improving brain tumor research in West Africa. We suggest that more attention be given to basic, clinical, and epidemiological brain ...

Abstract Background: This study was conducted to assess the dosimetric impact of FFF beam plans on high-grade brain neoplasms using VMAT technique when compared with FF plans. Material and Methods: Thirty patients neoplasms, who had received radiotherapy retrospectively were selected for this study. All planned 6MV_FF same plan re-optimized 6MV_FFF keeping dose constraint. Radiotherapy distribu...
