6th LAG-CLL Meeting 2026

WELCOME

The LAG-CLL Meeting is the biennial flagship event of the Latin American Group on Chronic Lymphocytic Leukemia, born out of the growing interest in CLL in the region. Bringing together leaders in basic and clinical research, it has evolved into a unique platform for the exchange of biological and clinical data in Latin America.

Since its inception in 2013, the meeting has expanded with each edition: the first three meetings took place in Uruguay, Brazil and Argentina, respectively; the 2022 meeting was held online, and in 2024, it went back to an in-person format, turning into a regional benchmark in the field.

Welcome to the 6th LAG-CLL Meeting in 2026!

We will meet again on April 16 and 17, 2026, for a new edition, featuring two days of intense networking and outstanding academic discussions on CLL.. This time the setting will be the beautiful city of Mendoza, Argentina, at the foot of the Andes, recognized worldwide as the cradle of the Argentinian Vineyards.

This will be a golden opportunity to strengthen ties in the scientific community, inspire new collaborations, share advances in research, exchange ideas and deepen our knowledge on CLL, Join us for an unforgettable experience of science, discussion and networking in the heart of the Andes.
