Mac Sinise dead at 33: Son of Forrest Gump star Gary Sinise passes away after battle with rare cancer Chordoma – as actor pays heartful tribute: ‘In our hearts forever’

  • Mac Sinise died on January 5 this year after years of cancer treatments
  • He had worked with his father at the Gary Sinise Foundation
  • Mac also supported his father in the Lt. Dan Band on drums

Gary Sinise has shared the heartbreaking news that his son Mac Sinise has passed away at the age of 33.

The 68-year-old Forrest Gump actor revealed that his son died on January 5 after a years-long battle with the rare spine cancer Chordoma in a post shared on the Gary Sinise Foundation website on Tuesday.

Mac had worked with the foundation and supported his father’s Lieutenant Dan Band on drums until repeated spinal surgeries and the worsening of his cancer in recent years forced him to resign.

In a lengthy tribute to his son, Sinise recalled the twin tragedies of 2018, when his wife Moria was diagnosed with stage 3 breast cancer in June, before Mac was diagnosed with a cordoma in August.

While Moira would eventually go into remission after successful surgery to remove the lymph nodes, followed by chemotherapy and radiation, her son was not so lucky.

WHAT IS CHORDOMA?

Chordoma is a rare form of cancer in the bones of the skull and spine.

It is part of a family of cancers called sarcoma, which also includes cancers of the bones, cartilage, muscles and other connective tissue.

Chordomas generally grow slowly but are relentless and tend to come back after treatment.

Due to their proximity to critical structures such as the spinal cord, brain stem, nerves and arteries, they are difficult to treat and require highly specialized care.

1 in 125,000 people live with an agreement, and it mainly occurs in older people. There are no approved medications to treat it.
