Asian Pacific J Cancer Prev, 13, 637-640 IntroductionBrain tumors though not frequent, contribute significantly to morbidity because of their relatively poor survival rate. A number studies from Western countries has reported on the pattern, incidence and mortality of brain and central nervous system (CNS) tumors. But no population based data have hitherto been reported on the descriptive epidemiology of brain and CNS tumors from India. So an attempt has been made to present the descriptive analysis of malignant brain and CNS tumors from Delhi. Materials and MethodsThe data collected by Delhi Population Based Cancer Registry (PBCR) was utilized for this study. The Delhi PBCR was established 1986 in Dr. BRAIRCH, AIIMS, New Delhi with the aim of obtaining reliable cancer morbidity and mortality data among the Delhi urban residents. Delhi, the capital of India covers an area of 1483sq.kms. The age adjusted (world population) incidence rates were 3.9 per 100,000 for males and 2.4 per 100,000 for females. Gliomas were the most frequently reported histology both in males (26.6%) and females (23.2%). A male predominance in incidence was observed for all histological classifications. The rates in Delhi are low compared to the incidences reported from developed countries.

The FIF technique can be employed for UAM in place of wedge-based conformal treatment plans.

The surgical management of intrinsic brainstem tumors presents a surgical challenge; radical excision yielded a good outcome in the majority of cases. The authors propose a classification system for 'intrinsic' brainstem tumors for defining surgical strategy.
