Comparative Parameters of Occult and Multiple Brain Tumors In Human: The Implication for Therapy

Abstract

Background Brain cancer treatment is a difficult task, because of complex nature of physico-chemical properties of brain, central nervous system (cns) acting drugs and drug carriers. Methods In view of this, literatures were searched with a view to assessing comparative mathematical parameters of occult and multiple primary brain tumors and their therapeutic outcomes. A total of thirteen patients comprised of eight males and five females who had suffered either occult or multiple brain tumors were used for the study. Tumor parameters and their therapeutic prognoses were mathematically determined. The data were analyzed using a modified Kaplan-Meier method at 5 % level of significance. Results Findings have shown that occult tumors such as meningiosarcoma (65.4cm3), teratoma (268 cm3), solitary brain tumor (20.6–22.4 cm3) and gliosarcoma (31.1 cm3) as well as multiple primary brain tumors; meningioma/diffuse astrocytoma (47.7 cm3), glioblastoma multiforme/pituitary adenoma (164. 59 cm3) and planum sphenoidale meningioma/pituitary adenoma (26.52 cm3) are deadly. However solitary brain tumor (4.2 cm3), glioblastoma multiforme/pituitary adenoma (12.77 cm3) and multimeningioma/pituitary adenoma (0.70 cm3) have high survival rate. Generally tumor weight (4.2–144.0 g), tumor density (0.24–0.96), total population of tumor cells (9.5 x 108-2.5 x 1011, rate of tumor cell migration (1.10–48.0 cm2/yr) and tumor radius (0.55-4.0 cm) are relatively moderate to very high, signifying that occult brain tumors may generate faster and may be more difficult to treat chemotherapeutically, radiotherapeutically, immunologically and surgically. Brain tumors affect male and female of 2–79 years old. Conclusions The locations of tumors are parietal, temporal, frontal, thalamic, frontoparietal, stellar, and planum sphenoidale lobes. Both occult and multiple brain tumors are diagnosed when all forms of therapy would have been useless.
