Alex Duong’s battle continued until the very end. The actor and stand-up performer—recognized for playing gang leader Sonny Le in recurring appearances on CBS’s “Blue Bloods” and his dedicated performances at The Comedy Store in West Hollywood—passed away Saturday morning, March 28, 2026, at St. John’s Hospital in Santa Monica, California, after a year-long battle with an uncommon, fast-spreading cancer. He was 42.
On Friday evening, Duong experienced septic shock, which proved too much for his system after enduring months of chemotherapy and radiation treatments. Christina, his wife, along with Everest, their five-year-old daughter, visited him the evening prior to his passing, and he maintained sufficient consciousness to bid farewell to his young child.
A Dallas, Texas native, Duong was the sixth and youngest child born to parents who immigrated from Vietnam and China. He first sought a medical profession at Baylor University on a complete scholarship before changing direction toward show business—a risk that would transform him from a comedy club doorman in 2021 into a network television performer.
The diagnosis of alveolar rhabdomyosarcoma arrived after Duong experienced a headache in early 2025. What appeared to be a trivial concern became serious when coworkers observed his left eye protruding so dramatically that his supervisor ordered him to leave work. Doctors discovered a tumor obstructing blood circulation to his optic nerve, and a biopsy confirmed the mass was exceptionally aggressive.
The uncommon soft-tissue malignancy resulted in Duong losing sight in the afflicted eye and spread to his spinal column despite comprehensive radiation and chemotherapy treatments. The family lacked health coverage at the time of his diagnosis. By February, he had been confined to bed. Treatment expenses totaled approximately $400,000.
Throughout his professional life, Duong secured roles in numerous television programs. He portrayed Sonny Le on “Blue Bloods” in three episodes spanning 2021 to 2024, performing opposite Donnie Wahlberg in a recurring storyline that established him as a familiar presence to the program’s loyal viewership. Additional appearances featured “Dexter,” “The Young and the Restless,” “Pretty Little Liars,” “Everybody Hates Chris,” “90210,” “Mad TV,” and “Death Valley.” He contributed writing to Netflix’s “Historical Roasts” and participated in Comedy Central’s “Jeff Ross Presents Roast Battle” in 2018, where he became the first Vietnamese cis-male to perform on the show.
As reported by Deadline, Wahlberg had recently informed Duong to get ready for a forthcoming “Blue Bloods” spinoff—another part he would ultimately never perform. Prior to his diagnosis, Duong had arranged to tour 41 states during 2025, with certain performances alongside “The Daily Show” correspondent Ronny Chieng. His professional trajectory was ascending to unprecedented levels precisely when sickness intervened.
Throughout his medical battle, the Los Angeles stand-up community mobilized in Duong’s support. During August 2025, performers including Chieng, Atsuko Okatsuka, Andrea Jin, and Fumi Abe coordinated “The Alex Duong Has Cancer In His Eye Comedy Benefit Show” at Largo in Los Angeles, generating $10,000 for his medical care and household costs. Admission cost $60 per person, with supporters and fellow artists filling the space to assist a colleague in need.
“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.”
In 2021, Duong became part of the Comedy Store’s entrance staff—a role traditionally occupied by emerging comedians advancing toward the venue’s performance roster. Jeff Ross, a comedian who collaborated with Duong on “Jeff Ross Presents Roast Battle,” additionally shared condolences via social media, describing his passing as a “BIG loss for our @roastbattle @thecomedystore family.”
Since 2009, Duong maintained SAG-AFTRA membership, amassing appearances spanning comedy, drama, and soap opera categories during his almost twenty-year entertainment industry tenure. In motion pictures, he had roles in “Formosa Betrayed,” “The Beyond,” and “Sideways for Attention.”
Soft tissue is affected by alveolar rhabdomyosarcoma, which predominantly strikes adolescents and young adults. The American Cancer Society reports that between 350 to 400 new childhood rhabdomyosarcoma diagnoses happen annually throughout the United States, with the alveolar variant accounting for roughly 20 to 30 percent of such instances. Among adults like Duong, the condition occurs far less frequently and presents worse prognoses—median overall survival for adult patients is just 3.6 years from diagnosis.
The fundraising initiative created on GoFundMe for Duong’s treatment costs has exceeded $124,000 toward an adjusted $200,000 target. The contributions will assist his family’s continuing requirements. Contributors have included businessman, producer, and comic Byron Allen. A celebration of life is planned for April 17 at Hollywood Forever Cemetery in Los Angeles. Rather than flowers, the family requests that contributions be directed toward supporting his daughter Everest’s future.
Christina, his wife, and Everest, his daughter, survive Duong. In his last Instagram update on January 28, 2026, Duong shared a video from a friend providing supporters with information about his worsening health. His message below the video—”I will walk out of here”—embodied the determination of a warrior who declined to give up, even as circumstances became insurmountable.
