The Neuro-Oncology Scientific
Club (NOSC), on its way to
grow
NOSC was established almost two years ago and continued to grow and consolidate. This scientific-professional community aims to help improving the management of brain tumors through a collaborative approach and the ongoing patient support. NOSC with its neuro-oncology field experts and brain tumor care providers (over 200 members now), pursues its defined goals towards improving brain tumor patients care, survival and quality of life.NOSC comprises neuro-oncology professionals from various disciplines not limited to neurosurgery, radiation oncology, pathology, neuroradiology, hematology and oncology and neurology across Iran.
This scientific club owns provincial founding panels as well as a country-wide steering board. Given the endorsement and support received from the related national scientific societies, and the road map drawn by the steering committee , NOSC continues to strongly peruse its aim with the central belief that: together we can serve the brain tumor patients better.

First, Dr. Fazlalizadeh addressed the meeting with his welcome note. He emphasized that the allied societies taking role in the management of brain tumors should put together patient-centered interests to define shared strategies within NOSC. He further mentioned, when these ideas emerge, we should let them develop as opportunities for the exchange of expertise and optimized practice.These would not only serve the scholars and participants scientific needs but also be expected to improve our patients outcome.
NOSCs Steering Board Meeting Report
NOSC steering board held its first meeting to strategize future scientific/professional activities within the club.Following the initial endorsements NOSC received from the related national scientific societies, the steering board of this scientific club was formed.NOSCs steering boards central mission is to define its mid to long-term goals, strategies and tactics towards brain tumor patients better and extended lives.
The first NOSCs steering board meeting which was held on 7th March 2013, Tehran, was hosted by the Cancer Society of Iran. Present at the meeting were (alphabetically) : Dr.Amouheidari- Isfahan NOSC lead-faculty; Dr.Fazlalizadeh- Iranian Cancer Society; Dr. Ghadyani- Iranian Cancer Society; Dr.Hashemi-Iranian Radiology Society; Dr. Nayyeri- Iranian Radiology Society; Dr. Nilipour-Iranian Pathology Society; Dr.Samiei- Iranian Society of Radiation Oncology; Dr.Seyednejad- Tabriz NOSC lead-faculty and Dr.Tabatabaeefar-Iranian Society of Radiation Oncology. For informed reasons some invitees including Dr. Ansari- Shiraz NOSC lead-faculty; Dr.Anvari-Mashhad NOSC lead-faculty; Dr. Haddad-Iranian Society of Radiation Oncology; Dr.Vosough- Iranian Society of Pediatric Hematology-Oncology; Dr. Zali- National Society of Surgeons (Neurosurgery Branch) and Dr.Zendehdel- National Cancer Research Network, could not attend the meeting.

Such forums as NOSC can be utilized as a common place for case presentations through which the cross-talk between disciplines can solve many hard-to-tackle issues.Then, Dr.Samiee continued by sharing the positive feeling he had to see experts with brain tumor interest coming from different societies, around a table. He encouraged all societies to support not only NOSC but all similar interdisciplinary communities similarly aiming at oncology patients better life. While recognizing the distinctive role of NOSCs organizing committee under Behestan Darous (BD) support, he recommended that NOSC should be strategically steered by the societies (through their official delegates) in order to continue receiving support and endorsement from the health authorities and policy makers. This will allow NOSC become more authorized and visible in a national scope; he indicated. Later, Dr.Tabatabaeefar refocused on the issue that this club is not intended to belong to a specific group or society. NOSC would remain under the umbrella of all contributing societies as all agreed. Since start, NOSC tried to brand itself as a scientific community disclosing no competing or distinct commercial interest, even though the whole concept was initiated and supported by BD. BD is the main organizer putting together collaborators and members to run NOSC. Moreover, the present steering board is behind all decisions made to let this scientific club pursue its aims. We are here to help this collaborative functional group continue its journey towards optimizing neuro-oncology practice and helping our patients the best we can, he said.
Other contributors such as Dr.Amouheidari and Dr. Hashemi discussed the significance of such activities when related societies equally interact. This will be a major step forward in neuro-oncology practice across Iran, they agreed. Dr.Ghadyani commented on the pivotal role of the steering board and that NOSC can seek registration with the ministry of health as a focus-group and functions independently. Later on, when NOSC becomes a well-established and organized community, societies may take over to further officialize the club. Dr.Samiee, however, was not in agreement and shared his self-experience with the process of officializing such activities. As he indicated, there is no upfront limitations and obstacles to engage societies from the beginning. Most of the participants agreed with the latter ( i.e. top-down) approach. Other delegates including Dr. Nilipour, Dr.Nayeri, Dr.Hashemi and Dr.Seyednejad, commented on the importance of the connect-approach with regard to neuro-oncology applied science and patient care. Documentation of shared updates together with the evidence-based experiences can effectively provide a common pool for all scholars and clinicians in the field to communicate and transfer their expertise in order to find solutions to optimally manage patients. This has been something NOSC tried to render so far. Since NOSCs scientific contributions to the field have strongly been perceived effectual, all participants agreed that parallel to the official process under the societies umbrella, NOSC should continue its scientific activities even stronger than before.

The International Brain Tumor Awareness Week
The 7th International Brain Tumour Awareness Week
will be held between
(27 October - 2 November, 2013).
We as NOSC members plan to organize activities to increased awareness about brain tumors. Public awareness will be addressed using posters and leaflets during this
week. By this, NOSC expects to further draw attention to the particular challenges of a brain tumor and the need for a special response and an increased research effort.
To better aware the brain tumor patients of their condition and to provide patient
education, NOSC editorial has prepared some fact-sheets in Farsi addressing some of
the main questions brain tumor patients have.
These fact-sheets are supposed to be widely distributed to brain tumor patients before
and during the international brain tumor awareness week .

Highlights from
ASCO 13
4 June 2013The results of two important clinical trials on
glioblastoma were presented at the annual meeting
of the American Society of Clinical Oncology
(ASCO) held in Chicago during 31 May 4 June
2013. The two trials were AVAglio (progression-
free survival and health-related quality of life
involving temozolomide and radiotherapy plus
bevacizumab in newly-diagnosed GBM, abst#
2023) and RTOG 0825 (a double-blind placebo-
controlled trial of bevacizumab in patients with
newly-diagnosed GBM). The results created
discussion and controversy.
Dr. Mark Gilbert, from the MD Anderson Cancer
Center, who presented the RTOG 0825 results
was reported as stating that in relation to using
bevacizumab in newly-diagnosed GBM: Our study
would strongly suggest that it is not beneficial to do
it as front-line treatment but to reserve it as
second-line or salvage therapy.
Some commentators worried that the overall
results might have an adverse effect on the US
Food and Drug Administrations (FDA) sort of
conditional approval for bevacizumab and brain
tumours in 2009. The worry revolves around the
survival advantage as expressed by progression-
free survival (PFS) and overall survival (OS) but
Dr. Richard Pazdur from the FDA was reported in
the New York Times as stating We have approved
a lot of drugs without a survival advantage.
Brain tumour patient advocates
need to be alert to this ongoing
debate about the measurement of
the survival advantage of new
therapies for brain tumours and
express their views when
necessary.
Meanwhile, in a relatively little-
reported media release on 17 June
it was stated that bevacizumab had
been approved in Japan for newly-
diagnosed GBM in combination
with TEMOZOLOMIDE plus
RADIOTHERAPY and as
monotherpy for recurrent GBM.
The approval was based on the
Phase II BRAIN study, a Japanese
Phase II study (JO22506) and the
Phase III AVAglio study.
Furthermore, it was stated that
applications for first-line treatment
have been filed in the European
Union and Switzerland. However ,
the FDA has not yet approved this
combination and according to the
so far established protocols, the
standard-of -care for GBM remains
six weeks concomitant
temozolomide and radiotherapy
followed by adjuvant
temozolomide.

13The Stupp regimen preceded by early post-surgery temozolomideversus the Stupp regimen alone in the treatment of patients with newly diagnosed glioblastoma multiforme (GBM).
J Clin Oncol 31, 2013 (suppl; abstr 2022)
Background: In treatment of newly diagnosed GBM with the Stupp chemo-radiotherapy regimen,following by adjuvant chemotherapy, patients were treated with temozolomide (TMZ) & combinedradiotherapy 4-5 weeks after surgery. In the interval between surgery and chemo-radiotherapy, it is notknown whether additional TMZ treatment will improve efficacy or safety. This trial evaluated the safetyand efficacy of the Stupp regimen + early post-surgery TMZ chemotherapy in the treatment of patientswith newly diagnosed GBM. Methods: The trial was a multi-center, randomized open-label study. 99newly diagnosed GBM patients were enrolled and randomly assigned to the Stupp regimen + early post-surgery TMZ chemotherapy arm (experimental group, n = 52) or to Stupp regimen alone (control group,n = 47). Fourteen days after surgery, the patients in experiment group recieved TMZ orally at75mg/m2/day for 14 days. The primary endpoint of the study was the overall survival (OS). Thesecondary endpoints included the progression-free survival (PFS), objective tumor assessment andadverse events (AEs). Results: The median OS time was 17.58 months (95% CI: 15.18 23.03 months)in the experiment group and 13.17 months (95% CI: 11.14 18.76 months) in the control group (log-rank test, p = 0.021). There is no significantly difference in the median PFS between experiment groupand control group (8.74 months, 95% CI: 6.41-14.85 months vs 10.38 months, 95% CI: 8.18-15.44months, p = 0.695). No statistically significant difference was detected as regards to the objective tumorassessments. There is no significance in OS or PFS between MGMT positive and MGMT negativegroups. TMZ treatment was well tolerated in the study. AE types and rates were generally similarbetween the two groups. There were 22 SAEs in this study, with only 1 SAE (lung infection) in Stuppregimen group was possibly drug-related. Conclusions: The addition of early post-surgery TMZchemotherapy to the Stupp regimen for newly diagnosed GBM resulted in a statistically significantsurvival benefit with minimal additional toxicity. Clinical trial information: NCT00686725.

Neuro-Oncology News Blast
June 2013: Circulating microparticles of glial origin andtissue factor bearing in high-grade glioma: a potentialprothrombotic role.
Venous thromboembolism (VTE) may complicate the clinical course ofglioblastoma multiforme (GBM). Circulating microparticles (MPs) have beenassociated with cancer-related VTE. Sixty-one consecutive patients with GBMundergoing gross-total (41) or subtotal (20) surgical resection followed by radio-chemotherapy
were prospectively evaluated. MPs numbers according to cellular origin and the procoagulantactivity of annexin V positive (AV+) MPs (MP-activity) were measured before surgery and then1 week and 1, 4, and 7 months after surgery. Glial (GFAP+) and endothelial (CD62E+) derivedMPs, AV+ and tissue factor-bearing (TF+) MPs were measured using flow cytometry. Baselinelevels of GFAP+/TF-, TF+/GFAP-, and GFAP+/TF+ MPs were significantly higher in GBMpatients than in healthy controls, and significantly increased at each time point after surgery; at7 months, a further significant increase over the level found a week after surgery was only seenin the subtotally resected patients. The number AV+/CD62E- MPs increased in GBM patientsand correlated with MP activity. TF+/GFAP- MPs numbers were significantly higher in 11 GBMpatients who developed VTE than in those who did not (p 0.04). TF+/GFAP- MPs levels abovethe 90th percentile (calculated in GBM patients without VTE) were associated with a higher riskof VTE (RR 4.17, 95% CI 1.57-11.03). In conclusion, the numbers of glial-derived and/or TF-bearing MPs were high in GBM patients both before and even more after the neoplasmwas treated, especially in patients with subtotal resection likely according to diseaseprogression. A contribution of TF+/GFAP- MPs to the risk of VTE is suggested.Thromb Haemost. 2013 Jun 27;110(2)http://www.ncbi.nlm.nih.gov/pubmed/23803674
Jan 2013: Mechanisms of evasive resistance to anti-VEGF therapy in glioblastoma.
Angiogenesis inhibitors targeting the VEGF signaling pathway have been US FDA approved for various cancers including glioblastoma (GBM), one of the most lethal and angiogenic tumors. This has led to the routine use of the anti-VEGF antibody bevacizumab in recurrent GBM, conveying substantial improvements in radiographic response, progression-free survival and quality of life. Despite these encouraging beneficial effects, patients inevitably develop resistance and frequently fail to demonstrate significantly better overall survival. Unlike chemotherapies, to which tumors exhibit resistance due to genetic mutation of drug targets, emerging evidence suggests that tumors bypass antiangiogenic therapy while VEGF signaling remains inhibited through a variety of mechanisms that are just beginning to be recognized. Because of the indirect nature of resistance to VEGF inhibitors there is promise that strategies combining angiogenesis inhibitors with drugs targeting such evasive resistance pathways will lead to more durable antiangiogenic efficacy and improved patient outcomes. Further identifying and understanding of evasive resistance mechanisms and their clinical importance in GBM relapse is therefore a timely and critical issue.

In collaboration with the NOSC lead-faculty members in Mashhad, Dr. Anvarihas notably contributed to the so far conducted NOSC activities there. He has been a member of the NOSC founding panel and the moderator of the so far conducted scientific activities. He also functions as a member of NOSC steering committee across the country. Since last year, Dr. Anvari has invited distinguished oncologists - pathologist -immunologist and geneticist to form a CNS tumor study group in Mashhad. This study group has been working on defined brain tumor research projects in collaboration with the Oncology Research Center and related authorities in Mashhad University of Medical Sciences.
The rationale for the continuation of NOSCs scientific patient-oriented activities was agreed upon during this meeting. Everybody was in line with the pre-specified mission and vision of this scientific club. Attendees agreed that further steering board meetings should be conducted during which many detailed questions will be addressed. Exploring some central questions such as : Radio-diagnostic advances in CNS tumors; how this can optimize care?; Safe maximal resection of brain tumors and functional surgery set up; where? when? how?; Brain tumor tissue bank, ifs and buts!; Brain tumor collaborative registry (BTCR), how to make it a real success?; Priorities in forth coming provincial NOSC meetings?; Co-chair panel and speakers for the following NOSC sessions?; Newsletter, comments? NOSC case study periodical, how to boost contributions? NOSC membership?; International collaborations (International members/patrons?); International speakers board?; NOSC member, faculty and lead-faculty definition?; Brain tumor joint seminars (problem case discussions)? Where/when to hold such a thing? would line up NOSCs future strategies even clearer, and are expected to be the main constituent of the future steering board meetings.Cancer society has graciously accepted to host this session and even
further gatherings while re-emphasized that NOSC belongs to all contributing societies. Participants were delighted for this invitation and agreed to expect invitation to the following NOSC steering board meeting issued by the cancer society of Iran aiming to catalyze the steering boards planned activities.NOSC is to receive support from national scientific societies contributing to such a viable field; the Neuro-Oncology.
Disclosure: Conduction of the NOSCs steering board meeting was made possible through logistic supports from Behestan Darou PJS.
