Alex Duong maintained his fighting spirit until the end. The performer and comedian—recognized for his repeating character as gang leader Sonny Le on CBS’s “Blue Bloods” and his dedicated performances at The Comedy Store in West Hollywood—passed away on Saturday morning, March 28, 2026, at St. John’s Hospital in Santa Monica, California, after a year-long battle with a rare, aggressive cancer. He was 42.
Duong experienced septic shock on Friday night, which overtook his body following months of chemotherapy and radiation. His wife, Christina, and their five-year-old daughter, Everest, visited him the evening prior to his passing, and he stayed conscious enough to bid farewell to his young child.
Born in Dallas, Texas, Duong was the sixth and final child to Vietnamese and Chinese immigrant parents. He first aimed for a career in medicine at Baylor University on a full scholarship before changing his path to entertainment—a risk that would carry him from comedy club doorman in 2021 to network television actor.
Duong’s diagnosis with alveolar rhabdomyosarcoma occurred after he experienced a headache in early 2025. What began as an apparently minor problem intensified when coworkers observed his left eye bulging so dramatically that his boss directed him home from work. Medical testing uncovered a tumor obstructing blood flow to his optic nerve, and a biopsy confirmed the growth was extremely aggressive.
The rare soft-tissue cancer resulted in Duong losing his vision in the affected eye and spread to his spine despite comprehensive radiation and chemotherapy. The family lacked health insurance when he was diagnosed. By February, he had become bedridden. Medical costs totaled approximately $400,000.
Duong performed in dozens of television shows throughout his career. He portrayed the role of Sonny Le on “Blue Bloods” across three episodes between 2021 and 2024, collaborating alongside Donnie Wahlberg in a recurring arc that made him a recognizable face to the show’s dedicated audience. His credits also included “Dexter,” “The Young and the Restless,” “Pretty Little Liars,” “Everybody Hates Chris,” “90210,” “Mad TV,” and “Death Valley.” He wrote for Netflix’s “Historical Roasts” and competed on Comedy Central’s “Jeff Ross Presents Roast Battle” in 2018, where he became the first Vietnamese cis-male to perform on the show.
According to Deadline, Wahlberg had recently told Duong to prepare for an upcoming “Blue Bloods” spinoff—one more role he would never get to play. Before his diagnosis, Duong planned to tour 41 states throughout 2025, with some dates alongside “The Daily Show” correspondent Ronny Chieng. His career was reaching new heights just as illness struck.
The Los Angeles comedy community mobilized around Duong throughout his illness. In August 2025, comedians including Chieng, Atsuko Okatsuka, Andrea Jin, and Fumi Abe organized “The Alex Duong Has Cancer In His Eye Comedy Benefit Show” at Largo in Los Angeles, raising $10,000 for his treatment and family expenses. Tickets sold for $60 each, with fans and fellow performers packing the venue to support one of their own.
“Comedians always have each other’s backs when times are ****,” Duong told the Los Angeles Times about the support he received during treatment. “We know how hard it is to pine and struggle and scrape by in this lifestyle, just so we can do these jokes and keep improving.”
Duong joined the Comedy Store’s door staff in 2021—a position historically held by aspiring comedians working their way into the club’s lineup. Comedian Jeff Ross, who worked with Duong on “Jeff Ross Presents Roast Battle,” also paid tribute on social media, calling his death a “BIG loss for our @roastbattle @thecomedystore family.”
Duong had been a member of SAG-AFTRA since 2009, accumulating credits across comedy, drama, and soap opera genres throughout his nearly two-decade career in entertainment. On the film side, he appeared in “Formosa Betrayed,” “The Beyond,” and “Sideways for Attention.”
Alveolar rhabdomyosarcoma affects soft tissue and typically impacts adolescents and young adults. According to the American Cancer Society, roughly 350 to 400 new pediatric cases of rhabdomyosarcoma occur each year in the United States, with the alveolar subtype representing about 20 to 30 percent of those cases. In adults like Duong, the disease is significantly rarer and carries poorer outcomes—median overall survival for adult patients is just 3.6 years from diagnosis.
The GoFundMe campaign established to help with Duong’s medical expenses has surpassed $124,000 toward a revised $200,000 goal. The funds will support his family’s ongoing needs. Donors have included businessman, producer, and comic Byron Allen. A memorial service is scheduled for April 17 at Hollywood Forever Cemetery in Los Angeles. Instead of flowers, the family asks that donations be made to support his daughter Everest’s future.
Duong is survived by his wife, Christina, and daughter, Everest. In his final Instagram post on January 28, 2026, Duong reposted a video from a friend updating fans on his deteriorating condition. His comment beneath the video—”I will walk out of here,”—captured the spirit of a fighter who refused to surrender, even when the odds turned impossible.
