The trendy dosing schedule of temozolomide is five consecutive days of daily dosing at some stage in 28-day cycles. However, exceptional dosing schedules can also produce higher effects, together with non-stop every day dosing the use of decrease quantities of drug (e.G. 21-day dosing for the duration of 28-day cycles). As an instance of an altered dosing agenda, promising outcomes were proven the usage of decrease day by day doses on each day for 7 weeks, observed via a 4-week off periods. Regarding the duration of dosing, for oligodendrogliomas the duration prescribed by means of oncologists varies considerably and appears to range from 6 cycles to over 32 cycles (i.E. Over 3 years). In one have a look at, researchers in comparison sufferers who acquired temozolomide for as a minimum 12 months at the 5/28 day cycle, dividing such patients into two businesses: "quick time period" sufferers receiving temozolomide for 12–18 cycles and people "long term" sufferers receiving 19 or more cycles (range turned into 19 to 32 cycles). Researchers found that there was a statistically huge advantage for "long term" treatment (median development free survival for "quick term" patients changed into 95 weeks (comply with up of seventy three weeks), but for "long time" patients the median progression loose survival turned into now not yet reached (comply with up of 134 weeks)).

Because of their diffusely infiltrating nature, oligodendrogliomas cannot be absolutely resected and aren't curable via surgical excision. If the tumor mass compresses adjoining brain systems, a neurosurgeon will normally eliminate as a good deal of the tumor as he or she will be able to with out adverse other crucial, healthful mind systems. Surgery can be followed up via chemotherapy, radiation, or a mix of each, but current research advocate that radiation does not improve basic survival (even when age, medical records, histological grading, and form of surgical operation are considered).
