There are five ad-hoc committees within the SIOG governance.

Corporate Relations ad-hoc Committee

The SIOG Corporate Relations ad-hoc Committee is responsible for all corporate & industry relations of the Association (including fundraising) and in particular linked to the SIOG annual conference and other educational events. It ensures that corporate activities at SIOG conferences and the investment of industry in other SIOG ventures are in the best interests of the Association. The committee reviews and approves potential, new or alternative revenue generating opportunities with a view of protecting the financial well-being and integrity of the Association. It is also the platform wherein matters concerning industry such as changes in industry regulations, future collaborations and long terms initiatives involving industry are discussed.

Chair: Etienne Brain (France)
Matti Aapro (Switzerland)
Stuart Lichtman (USA)
Hans Wildiers (Belgium)

Geriatricians ad-hoc Committee

The SIOG Geriatrics ad-hoc Committee is for geriatricians who are interested in geriatric oncology, and who seek a forum of fellow geriatricians to share ideas and experiences in clinical practice and research. The committee is also a resource for SIOG to involve dedicated geriatricians in projects and conferences.

Marije Hamaker (Netherlands)

Currently the committee has 28 members from Europe, North America, South America, Asia, and Oceania.
Interested in joining this ad-hoc committee, please contact the SIOG Head Office.

  • To form a support group for geriatricians starting out in geriatric oncology or who have a limited support network in their local/national community, through regular meetings and the possibility of mentorship/buddy system
  • To develop a pool of geriatric experts for
    o SIOG (-related) conferences including the Advanced Courses
    o Cancer specialists seeking geriatric/geriatric oncology expertise
    o Reviewers for the Journal of Geriatric Oncology
  • To discuss study ideas and find collaboration partners for research and clinical projects

The ad-hoc committee has links with the European Geriatric Medicine Society’s special interest group for Geriatric Oncology.

  •  Open invitation to all geriatricians:
    o Who are a SIOG member
    o Who have attended a SIOG conference in 2018 or 2019
    o Who have attend the SIOG advanced course
  • Digital meetings every two months
  • Face-to-face meeting at SIOG conference

Social Media ad-hoc Committee

The SIOG Social Media ad-hoc Committee shall maintain the Twitter channel of SIOG. It will work in conjunction with the SIOG Secretariat to promote the value of SIOG Membership and to support the efforts of the SIOG activities.

Surgical ad-hoc Committee

The SIOG Surgical ad-hoc Committee (SAHC) is an integral part of the SIOG as is surgery an integral part of treatment of senior adults affected by solid malignancies.  As surgery is always evolving so is the SAHC, that is constantly looking for and welcoming new members who share the passion for the care of older patients.

The Surgical ad-hoc Committee is an integral part of the SIOG as is surgery an integral part of treatment of senior adults affected by solid malignancies. As surgery is always evolving so is the SAHC, that is constantly looking for and welcoming new members who share the passion for the care of older patients.

The times we are living in will be remembered by healthcare providers for the significant ‘contradictions’ in the medical and surgical care of older patients with cancer. On one hand it has been documented how chronological age per se does not contraindicate surgical management at any time in life; on the other hand the vast majority of senior cancer patients are routinely undertreated as a consequence of unproven assumptions. This group of cancer patients is likely to receive suboptimal treatment, either under-treatment as well as over-treatment. The function of the SAHC is to eliminate the myth that the senior adults are not candidates for surgery and this is to be done within the society and to the rest of the world per se.

The role of the SAHC inside the International Society of Geriatric Oncology is mainly to establish evidence that could help clinicians in being more aware and proactive about several issues.

There is a poor understanding of cancer in older patients. Solid tumors are detrimental at any age as shown for colorectal, breast and pancreatic cancer while surgery is still the number one option to treat solid cancer, above all in senor adults. When appropriately chosen it could be curative or good palliative procedure.

A prejudice about life expectancy is usually preventing cancer specialists whether it be medical, surgical, radiation oncologists or geriatricians to offer the best possible treatment. In the USA a 75-year old male in good health has 18 more years in front of him and 10 years at the age of 82i. The presence of severe comorbidities shrinks life expectancy to 6 and 2 years respectively, which is still a far longer period when compared to the average overall survival of untreated cancer subtypes.

Even though there is significant education going on among the surgeons there are several among the community who are hesitant to operate on older patients just because of the chronological age. Education is the key and there needs to be a valiant effort on the part of the society to show that there is vast available data demonstrating how fit older individuals can successfully undergo most complex invasive procedures with good quality of life outcomes.

The work of the SAHC began about a decade ago when the PACE studyii proved that the assessment of frailty in every older patients undergoing surgery accurately predicts the operative mortality, morbidity and costs. This was achieved by means of a non-cancer-specific tool (Comprehensive Geriatric Assessment – CGA). In 2014, another SAHC effort, the PREOP studyiii, showed that the complex and time consuming CGA, could be replaced by quick and surgeon-friendly tools like the “Timed Up-and-Go” test and how nutrition has to be optimized to minimize complications. Lately, the SAHC together with the European Society of Surgical Oncology (ESSO), developed the GOSAFE studyiv. The research recently completed accrual and will be soon able to provide prospective, original data about quality of life and functional recovery of older patients undergoing major oncological surgery. The ambitious endpoint of this international prospective registry is to take a real-time-picture of the ultimate outcomes achieved when delivering personalized care to fit, vulnerable and frail cancer patients (including cognitive impairment).

The role of the SIOG-SAHC is precisely to promote an individualized surgical standard. We realize that personalized treatment does not stand on targeting molecular biomarkers but on putting real-life patients needs as the ultimate goal of our care.

The way the SAHC is preparing for the future is primarily to implement the network of clinicians that has been proficiently developed during the process of the PACE, the PREOP and the GOSAFE studies. This group of motivated surgeons with a common goal is open to the challenges that older adults with cancer face and focused on organ-specific malignancies.

The SAHC members are ambassadors not only in the oncological field in general, but in the organ-specific Scientific Societies. Their role is to promote a more rational and personalized treatment of solid cancer in older patients by collaborating on scientific sessions, guidelines, research studies with the main Scientific Societies (i.e. ESSO, ASCRS, ESCP, SSO). In 2018, the first SIOG-SAHC, ESSO, ESCP, ACS Commission on Cancer join work has been published in the form of expert recommendations on personalized management of older patients with Rectal Cancerv.

SAHC members will more and more function as vectors for the knowledge developed by the experience in the SIOG into other scientific groups.

Further research projects by the SIOG-SAHC, following the GOSAFE, will focus on cancer surgery prehabilitation, biological age predictors, cancer biology in senior adult as few of the fields which requires immediate attention.
