• Selection policy

SIOP Asia Congresses are held on an annual basis, as per decision of the SIOP Asia Board. Please note the following guidance.

1. The bid should be proposed by a SIOP member in active status (with membership fees paid in the current calendar year). Any person with intersts in paediatric oncology may join SIOP as a member at https://siop-online.org/become-a-member/ or contact membership@siop-online.org to check if you are already a member. The SIOP member may be working or be affiliated with the bidding organization (hospital, national pediatric oncology society or center).
2. The Congress takes place in the first half of the calendar year, using April or May (because we need to maintain some distance from the main Annual SIOP Congress which is usually in Sept-Oct).
3. Bids are submitted at least 2 years before the date of the Congress to allow sufficient planning time. Bid deadline should be at least one month prior to the date of the Annual SIOP Congress.
4. The teams bidding to host should make a formal proposal at the SIOP Asia Annual Business Meeting (ABM) which takes place during the SIOP Annual Congress in Sept/Oct.
5. If there is only one submission that year, and if this is supported by the majority of the SIOP Asia members via a vote, the bid will be successful.
6. If there are more than 1 bids, the teams should make presentations at the ABM and answer questions from members. The SIOP Asia members will vote in a vote administered by the SIOP Secretariat.
7. The winning bid shall be announced prior to the end of the calendar year. Asia members should be informed by email.
8. The Local Organizing Committee (LOC) shall collaborate with CCI to organize and deliver a joint program for the Asia Congress.
9. The Scientific Program shall be designed with the SIOP Asia President who may seek inputs and collaboration from the Board if needed.
10. SIOP Asia members shall have discounted rates.

The Congress site will be rotated between the Western Asia and Eastern Asia. Please refer to the map for an indication on which countries fall in what area. The rotation is expected to provide more opportunities for our members to easily access the scientific meetings.
