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.
In 1969, Chavez actually led a march to the Mexican border to protest illegal immigration, accompanied by Sen. Walter Mondale and Ralph Abernathy, whom alert readers will recognize as Martin Luther King's successor as head of the Southern Leadership Conference.ccording to a 2006 article in The American Conservative by Steve Sailer, although Chavez's union, the United Farm Workers, did manage to raise wages significantly for stoop laborers from 1965 to 1981, those gains have largely disappeared for one reason: illegal immigration.
