Overview
- Coverage notes Landon publicly announced a pancreatic cancer diagnosis in early April 1991 after doctors found the tumor had spread to his liver.
- He began chemotherapy on April 18, 1991 and received an experimental drug in early May as he pursued both medical and complementary approaches.
- Archival footage and memoirs record that his May 9, 1991 appearance on Johnny Carson’s Tonight Show showed visible weight loss and a recognition that recovery was unlikely.
- Friends and colleagues say Landon stayed in close contact with loved ones during his final weeks, called Carson to offer condolences during a family tragedy on June 21, 1991, and died at his Malibu ranch on July 1, 1991 with his wife Cindy at his side.
- The pieces place his death within a long TV career—from Bonanza to Little House on the Prairie—and note that five-year survival for pancreatic cancer was about 4% then and has only modestly improved to roughly 10–13% today, underscoring the bleak prognosis he faced.
