Another related concept is that neoadjuvant therapy acts on micrometastatic disease. The downstaging is then a surrogate marker of efficacy on undetected dissemination, resulting in improved longtime survival compared to the surgery-alone strategy.
Mexican-American Cesar Chavez (1927-1993) was a prominent union leader and labor organizer. Hardened by his early experience as a migrant worker, Chavez founded the National Farm Workers Association in 1962. His union joined with the Agricultural Workers Organizing Committee in its first strike against grape growers in California, and the two organizations later merged to become the United Farm Workers.
Today we tell about one of the great labor activists, Cesar Chavez. He organized the first successful farm workers union in American history. Cesar Chavez was born on a small farm near Yuma, Arizona in 1927. In the late 19th century, Cesario Chavez, Cesar's grandfather, had started the Chavez family farm after escaping slavery on a Mexican farm. Cesar Chavez spent his earliest years on this farm.
