As an ACCME-accredited continuing medical education (CME) activity, the World Conference in Lung Cancer (WCLC) 2026 must comply with the ACCME Standards for Integrity and Independence. Accordingly, ineligible companies may not register or pay registration fees on behalf of individual healthcare professionals. An ineligible company is defined by the ACCME as any entity whose primary business is producing, marketing, selling, re-selling, or distributing healthcare products used by or on patients. All participants must register and remit payment individually. Any registration that is completed, submitted, or paid for directly by an ineligible company on behalf of an individual learner is not permitted and may be subject to cancellation.

Solicitation of delegates, distribution of promotional materials, marketing activities, hosting events or meetings are only permitted within an organization’s contracted exhibit booth, during their official symposium/meeting space, or with express authorization from the IASLC. Any promotional activity outside of these designated areas, including within the venue or associated hotels, is not permitted. Individuals or organizations engaging in unauthorized activities, regardless of registration type, may be asked to stop immediately and may be removed from the conference without refund.
