Abstract
The different drugs and medical devices, which are commercialized or under industrial development for glioblastoma treatment, are reviewed. Their different modes of action are analyzed with a distinction being made between the effects of radiation, the targeting of specific parts of glioma cells, and immunotherapy. Most of them are still at a too early stage of development to firmly conclude about their efficacy. Optune, which triggers antitumor activity by blocking the mitosis of glioma cells under the application of an alternating electric field, seems to be the only recently developed therapy with some efficacy reported on a large number of GBM patients. The need for early GBM diagnosis is emphasized since it could enable the treatment of GBM tumors of small sizes, possibly easier to eradicate than larger tumors. Ways to improve clinical protocols by strengthening preclinical studies using of a broader range of different animal and tumor models are also underlined. Issues related with efficient drug delivery and crossing of blood brain barrier are discussed. Finally societal and economic aspects are described with a presentation of the orphan drug status that can accelerate the development of GBM therapies, patents protecting various GBM treatments, the different actors tackling GBM disease, the cost of GBM treatments, GBM market figures, and a financial analysis of the different companies involved in the development of GBM therapies.

Abstract
For over six decades intra-arterial (IA) drugs have been sporadically used for the treatment of lethal brain diseases. In recent years considerable advance has been made in the IA treatment of retinoblastomas, liver and locally invasive breast cancers, but relatively little progress has been made in the treatment of brain cancers. High resting blood flow and the presence of the blood-brain barrier (BBB), makes IA delivery to the brain tissue far more challenging, compared to other organs. The lack of advance in the field is also partly due to the inability to understand the complex pharmacokinetics of IA drugs as it is difficult to track drug concentrations in sub-second time frame by conventional chemical methods. The advances in optical imaging now provide unprecedented insights into the pharmacokinetics of IA drug and optical tracer delivery. Novel delivery methods, improved IA drug formulations, and optical pharmacokinetics, present us with untested paradigms in pharmacology that could lead to new therapeutic interventions for brain cancers and stroke. The object of this review is to bring into focus the current practice, problems, and the potential of IA drug delivery for treating brain diseases. A concerted effort is needed at basic sciences (pharmacology and drug imaging), and translational (drug delivery techniques and protocol development) levels by the interventional neuroradiology community to advance the field.

Abstract
Computational modeling shows that intra-arterial delivery is most efficient when the delivered drugs rapidly and avidly bind to the target site. The cell-penetrating peptide trans-activator of transcription (TAT) is a candidate carrier molecule that could mediate such specificity for brain tumor chemotherapeutics. To test this hypothesis we first performed in vitro studies testing the uptake of TAT by one primary and three potentially metastatic brain cancer cell lines (9L, 4T-1, LLC, SKOV-3). Then we performed in vivo studies in a rat model where TAT was delivered either intra-arterially (IA) or intravenously (IV) to 9L brain tumors. We observed robust uptake of TAT by all tumor cell lines in vitro. Flow cytometry and confocal microscopy revealed a rapid uptake of fluorescein-labeled TAT within 5 min of exposure to the cancer cells. IA injections done under transient cerebral hypoperfusion (TCH) generated a four-fold greater tumor TAT concentration compared to conventional IV injections. We conclude that it is feasible to selectively target brain tumors with TAT-linked chemotherapy by the IA-TCH method.

Abstract
Effective treatment for glioblastoma (GBM) will likely require targeted delivery of several specific pharmacological agents simultaneously. Intra-arterial (IA) delivery is one technique for targeting the tumor site with multiple agents. Although IA chemotherapy for glioblastoma (GBM) has been attempted since the 1950s, the predicted benefits remain unproven in clinical practice. This review focuses on innovative approaches to IA drug delivery in treating GBM. Guided by novel in vitro and in vivo optical measurements, newer pharmacokinetic models promise to better define the complex relationship between background cerebral blood flow and drug injection parameters. Advanced optical technologies and tracers, unique nanoparticles designs, new cellular targets, and rational drug formulations are continuously modifying the therapeutic landscape for GBM. Personalized treatment approaches are emerging; however, such tailored approaches will largely depend on effective drug delivery techniques and on the ability to simultaneously deliver multidrug regimens. These new paradigms for tumor-selective drug delivery herald dramatic improvements in the effectiveness of IA chemotherapy for GBM. Therefore, within this context of so-called "precision medicine," the role of IA delivery for GBM is thoroughly reassessed.

Abstract
BACKGROUND Optimizing liposomal vehicles for targeted delivery to the brain has important implications for the treatment of brain tumors. The promise of efficient, brain-specific delivery of chemotherapeutic compounds via liposomal vehicles has yet to be achieved in clinical practice. Intra-arterial injection of specially designed liposomes may facilitate efficient delivery to the brain and to gliomas. OBJECTIVE To test the hypothesis that cationic liposomes may be effectively delivered to both normal and glioma-bearing brain tissue utilizing a strategy of intra-arterial injection during transient cerebral hypoperfusion. METHODS Cationic, anionic, and neutral liposomes were separately injected via the internal carotid artery of healthy rats during transient cerebral hypoperfusion. Rats bearing C6 gliomas were similarly injected with cationic liposomes. Liposomes were loaded with DilC18(5) dye whose concentrations can be measured by light absorbance and fluorescence methods. RESULTS After intra-arterial injection, a robust uptake of cationic in comparison with anionic and neutral liposomes into brain parenchyma was observed by diffuse reflectance spectroscopy. Postmortem multispectral fluorescence imaging revealed that liposomal cationic charge was associated with more efficient delivery to the brain. Cationic liposomes were also readily observed within glioma tissue after intra-arterial injection. However, over time, cationic liposomes were retained longer and at higher concentrations in the surrounding, peritumoral brain than in the tumor core. CONCLUSION This study demonstrates the feasibility of cationic liposome delivery to brain and glioma tissue after intra-arterial injection. Highly cationic liposomes directly delivered to the brain via an intracarotid route may represent an effective method for delivering antiglioma agents.

Abstract
When a human cell detects damaged DNA, it initiates the DNA damage response (DDR) that permits it to repair the damage and avoid transmitting it to daughter cells. Despite this response, changes to the genome occur and some cells, such as proliferating cancer cells, are prone to genome instability. The cellular processes that lead to genomic changes after a genotoxic event are not well understood. Our research focuses on the relationship between genotoxic cancer drugs and checkpoint adaptation, which is the process of mitosis with damaged DNA. We examine the types of DNA damage induced by widely used cancer drugs and describe their effects upon proliferating cancer cells. There is evidence that cell death caused by genotoxic cancer drugs in some cases includes exiting a DNA damage cell cycle arrest and entry into mitosis. Furthermore, some cells are able to survive this process at a time when the genome is most susceptible to change or rearrangement. Checkpoint adaptation is poorly characterised in human cells; we predict that increasing our understanding of this pathway may help to understand genomic instability in cancer cells and provide insight into methods to improve the efficacy of current cancer therapies.

Abstract
Regional chemotherapy was developed in the 1950s and continues to play an integral part in the development of newer therapies for advanced solid malignancies. Regional therapies have evolved in complexity but are still based on the pharmacokinetics of drug delivery to solid malignancies. Newer techniques demonstrate that the combination of regional therapies, hyperthermia, and surgery is essential in promoting improved patient outcomes.

Abstract
The major efforts to selectively deliver drugs to the brain in the past decade have relied on smart molecular techniques to penetrate the blood-brain barrier, whereas intraarterial drug delivery has drawn relatively little attention. Meanwhile, rapid progress has been made in the field of endovascular surgery. Modern endovascular procedures can permit highly targeted drug delivery by the intracarotid route. Intracarotid drug delivery can be the primary route of drug delivery or it could be used to facilitate the delivery of smart neuropharmaceuticals. There have been few attempts to systematically understand the kinetics of intracarotid drugs. Anecdotal data suggest that intracarotid drug delivery is effective in the treatment of cerebral vasospasm, thromboembolic strokes, and neoplasms. Neuroanesthesiologists are frequently involved in the care of such high-risk patients. Therefore, it is necessary to understand the applications of intracarotid drug delivery and the unusual kinetics of intracarotid drugs.

Abstract
The effects of IV anesthetics are enhanced by increased cerebral blood flow (CBF) because of a greater delivery of drugs to the brain. In contrast, mathematical simulations suggest that a decrease in CBF, by increasing regional drug uptake and decreasing drug washout, enhances the efficacy of intraarterial drugs. We hypothesized that administrating intracarotid anesthetics during cerebral hypoperfusion will significantly prolong the duration of electroencephalographic (EEG) silence. We tested our hypothesis on New Zealand White rabbits. In the first group of 7 animals, we observed that decreasing CBF by approximately 70% attenuated, but did not abolish, EEG activity. Subsequently, 9 animals received 3 intracarotid injections of 3 mg of thiopental (thiopental-1, thiopental + hypoperfusion, and thiopental-2). The first and third injections were made under physiological conditions. The second drug injection was made during cerebral hypoperfusion. Compared with injection of thiopental-1 and -2, thiopental + hypoperfusion resulted in a profound increase in EEG silence (from 45 +/- 5 and 67 +/- 27 s, to 206 +/- 46 s, respectively, n = 9, P < 0.0001). The EEG recovery profile was similar during all three thiopental challenges. The study suggests that modulation of CBF is an important tool for enhancing intraarterial drug delivery to the brain.

Abstract
The treatment of serious drug or chemical poisoning relies mostly on the use of standard intensive care measures. Supplementation of intensive care with dialysis and hemoperfusion may be necessary at times to remove the intoxicant in seriously ill patients. Factors governing drug and chemical removal by dialysis and hemoperfusion are discussed, and guidelines given when to employ these techniques. Tables of drugs removed by both techniques are given for guidance. These tables will be updated regularly on the Advances in Renal Replacement Therapy website.

Abstract
PURPOSE To increase the dose of drug delivered to a tumor while maintaining tolerable systemic side effects, an interventional technique of isolated lower extremity infusion was investigated. MATERIALS AND METHODS Experiments were performed in eight dogs. Four dogs were treated by a combination of intraarterial (IA) femoral cisplatin infusion at a dose of 2.0 mg/kg with drug removal from the ipsilateral extremity venous blood by a dialyzer. The other four dogs comprised the control group. In these animals, left femoral arterial IA cisplatin infusion was performed without dialysis. Leukocyte and platelet counts, blood urea nitrogen (BUN) levels, and serum creatinine levels were recorded before and after the treatment. Subsequently, two human patients with inoperable osteosarcoma were treated with the isolated infusion. RESULTS In the experiments, 85%-90% of the free platinum that entered the dialyzer was removed. The peak systemic plasma cisplatin concentrations in animals undergoing dialysis were reduced by 81.25% compared to those in animals undergoing femoral IA infusion without hemodialysis. There were no significant changes in the hematologic profiles or BUN and serum creatinine levels in the experimental animals. However, in the control group, all dogs developed myelosuppression and severe renal toxicity after IA infusion of the same dose of cisplatin. Clinically, immediate relief of symptoms related to the primary tumor was achieved in both human patients after the combination of isolated IA infusion and embolotherapy. CONCLUSION Single-pass hemodialysis removed a significant amount of cisplatin after regional IA infusion, reduced systemic toxicity, and permitted survival of the experimental animals. In two patients with osteosarcoma, percutaneous isolated lower extremity chemotherapeutic infusion therapy and embolotherapy were performed safely with partial responses.

Abstract
BACKGROUND We performed a phase I study of a novel system of complete hepatic venous isolation and extracorporeal chemofiltration in patients with unresectable hepatocellular carcinoma (HCC) to determine (a) whether systemic exposure to doxorubicin could be limited after high-dose hepatic arterial infusion (HAI), and (b) the hepatic maximum tolerated dose (MTD) of doxorubicin. METHODS Ten patients with biopsy-proven HCC were treated with 20-min HAI of doxorubicin (17 total treatments). Two patients were treated with doxorubicin 60 mg/m2, three patients were treated at 90 mg/m2, and five patients received 120 mg/m2. A newly developed dual-balloon vena cava catheter was advanced from the femoral vein, and the balloons were inflated to isolate and capture total hepatic venous outflow. The hepatic venous blood was pumped through extracorporeal carbon chemofilters before return of the blood to the systemic circulation. RESULTS Peak systemic doxorubicin levels were an average 85.6% lower than were peak prefilter levels (p < 0.01). Because all catheters were placed percutaneously and because the chemofiltration markedly limited systemic chemotherapy exposure, patients were discharged 1 day after 16 of the 17 treatments. The hepatic and systemic MTD of doxorubicin in this treatment protocol was 120 mg/m2. CONCLUSIONS This novel system of complete hepatic venous isolation and chemofiltration limits systemic chemotherapy toxicity and will allow use of higher doses of chemotherapeutic agents to treat HCC.

Abstract
Aims Twenty-three patients with liver metastases from colorectal cancer were entered into a prospective, phase II pilot study to evaluate the efficacy and feasibility of intra-arterial high-dose chemoterapy (IAHC) + intraperitoneal chemotherapy (IPC) combined with hemofiltration. Methods All patients had abdominal laparotomy to position a hepatic artery infusion port and in 15 cases an implantable system for IPC. A double-lumen filtration catheter was placed in the vena cava via the saphenous or femoral vien and connected to a modified hemofiltration unit. The treatment schedule consisted of mitomycin (30-50 mg/m2) and epirubicin (60-90) mg/m2) as IAHC combined with cisplatin (60 mg/m2) given in a 2000 ml saline solution by IPC. The high-dose IAHC-IPC was followed by 4 cycles of intra-arterial standard dose chemotherapy through the arterial port-a-cath (6 mg/m2 mitomycin and 20 mg/m2 epirubicin) and if possible by another cycle of high dose IAHC-IPC. Results We delivered a toal of 31 cycles of IAHC, 21 of which were combined with IPC. Ten cycles of IAHC were administered without concurrent IPC because of painful adhesions, clinical contraindications or patient refusal. Seven of 23 patients (30%) were pretreated and with progressive disease after systemic chemotherapy. Among 22 evaluable patients, we obtained 2 complete remissions (9%) and 11 partial remissions (50%); moreover, 4 of 7 pretreated patients obtained a response to treatment. As a result, an objective tumor response was observed in 59% of patients (13/22). Therefore, a dose-response behavior was demonstrated also in tumors with a low chemosensitivity. The median duration of response and survival was 10 and 14 months, respectively. Toxicity was usually mild, but we reported one toxic death due to treatment complications. Conclusions Further prospective randomized studies are needed to confirm the results of our study.

Abstract
We evaluated a novel system of complete hepatic venous isolation and chemofiltration (CHVI-CF) to reduce systemic drug exposure following regional hepatic infusion of doxorubicin. Rabbits bearing hepatic VX-2 tumors were given doxorubicin via either hepatic arterial infusion (HAI) or portal venous infusion (PVI). A dual-balloon vena cava catheter and extracorporeal chemofilter were used to capture and filter hepatic venous blood in experimental animals. Control animals received chemotherapy without hepatic venous isolation and chemofiltration. Following a 5-min HAI of doxorubicin (3 or 5 mg/kg), control and experimental animals had similar doxorubicin levels in their livers and VX-2 tumors, but experimental animals showed a significant reduction in doxorubicin levels in systemic plasma, heart, and kidney tissue as compared with control animals (P < 0.01). HAI produced a 4-fold increase in doxorubicin levels in VX-2 tumors as compared with the drug levels obtained using PVI (P < 0.01). A single HAI of 3 mg/kg doxorubicin in animals treated with CHVI-CF produced marked tumor necrosis at 7 and 14 days after treatment. By increasing the total body clearance of doxorubicin, this system will allow HAI of higher doses of drug in attempts to improve the antitumor response.

Abstract
Chemotherapy for primary or metastatic hepatic malignancy is limited by poor tumor response and dose-related systemic toxicity. As an alternative to chemotherapy infusion by vein or by the hepatic artery, the authors have developed a percutaneous technique of isolated liver perfusion that allows the regional delivery of high-dose chemotherapy to the liver with little systemic toxicity. After placement of a hepatic artery infusion catheter, an 18-F double-balloon catheter is placed into the inferior vena cava through the opposite femoral vein. Balloons are inflated above and below the hepatic veins, thus isolating hepatic venous outflow. The effluent passes through fenestrations in the catheter and is pumped through charcoal hemoperfusion filters where the drug is removed. The filtered blood is returned to the patient through the internal jugular vein. Fifteen treatments have been conducted in eight patients in a phase I dose-escalation study with use of 5-fluorouracil (5-FU). While it is premature to assess tumor response to isolated liver perfusion, the data demonstrate that the procedure is safe and is tolerated by patients. Pharmacokinetic studies show a 5-FU extraction of up to 85%, with minimal drug leakage into the systemic circulation. This technique shows potential for improving liver tumor response while decreasing systemic toxicity.

Four of these dogs underwent simultaneous extracorporeal hemofiltration (ECH) of the hepatic venous effluent using a high-flow, dual-lumen catheter placed in the vena cava at the level of the hepatic veins. Platinum levels were measured in the plasma, urine, and ultrafiltrate and in kidney and liver tissue. ECH significantly reduced systemic drug exposure as measured by the AUC for free and total platinum, by urinary excretion, and by 24-h kidney levels. Regional liver levels were minimally affected. Recovery of platinum in the ultrafiltrate was 40% +/- 14%. ECH resulted in efficient extraction of platinum and reduced systemic drug exposure with relative preservation of regional hepatic drug exposure.

Abstract
The role of cytoreductive surgery alone as effective salvage therapy for immediate palliation and durable symptom-free remission was examined in 17 patients (six with astrocytoma, seven with anaplastic astrocytoma, and four with glioblastoma) who developed symptomatic tumor relapse after initial surgery and irradiation. Individuals with widely disseminated subependymal, bihemispheral, or brainstem involvement were excluded. After reoperation, patients with astrocytoma and anaplastic tumors have been observed for an average of 31 and 29 months, respectively. As of this writing, all 13 patients are alive without evidence of tumor progression. Three of the four patients with glioblastomas have died 5, 12, and 17 months after reoperation, respectively. The 14 surviving patients overall have a current average Karnofsky performance level of 95. The durability of surgically induced palliation alone, the safe limits of resectability, and the clinical features associated with a favorable surgical response have been examined. The results indicate that, in selected individuals, durable remissions can be achieved by adequate resection of symptomatic tumor mass.
