Glioblastoma treatment as now constituted offers increased survival measured in months over untreated patients. Because glioblastomas are active in synthesizing a bewildering variety of growth factors, a systematic approach to inhibiting these is being undertaken as treatment adjunct. The serotonin 7 receptor is commonly overexpressed in glioblastoma. Research documentation showing agonists at serotonin receptor 7 cause increased extracellular regulated kinase 1/2 activation, increased interleukin-6 synthesis, increased signal transducer and activator of transcription-3 activation, increased resistance to apoptosis and other growth enhancing changes in glioblastoma is reviewed in this paper. Because three drugs in wide use to treat thought disorders - paliperidone, pimozide and risperidone - are also potent and well-tolerated inhibitors at serotonin receptor 7, these drugs should be studied for growth factor deprivation in an adjunctive role in glioblastoma treatment.

In the effort to improve treatment effectiveness in glioblastoma, this short note reviewed collected data on the pathophysiology of glioblastoma with particular reference to intersections with the pharmacology of perphenazine. That study identified five areas of potentially beneficial intersection. Data showed seemingly 5 independent perphenazine attributes of benefit to glioblastoma treatment - i) blocking dopamine receptor 2, ii) reducing centrifugal migration of subventricular zone cells by blocking dopamine receptor 3, iii) blocking serotonin receptor 7, iv) activation of protein phosphatase 2, and v) nausea reduction. Perphenazine is fully compatible with current chemoirradiation protocols and with the commonly used ancillary medicines used in clinical practice during the course of glioblastoma. All these attributes argue for a trial of perphenazine's addition to current standard treatment with temozolomide and irradiation. The subventricular zone seeds the brain with mutated cells that become recurrent glioblastoma after centrifugal migration. The current paper shows how perphenazine might reduce that contribution. Perphenazine is an old, generic, cheap, phenothiazine antipsychotic drug that has been in continuous clinical use worldwide since the 1950's. Clinical experience and research data over these decades have shown perphenazine to be well-tolerated in psychiatric populations, in normals, and in non-psychiatric, medically ill populations for whom perphenazine is used to reduce nausea. For now (Summer, 2020) the nature of glioblastoma requires a polypharmacy approach until/unless a core feature and means to address it can be identified in the future. Conclusions: Perphenazine possesses a remarkable constellation of attributes that recommend its use in GB treatment.
