Ron Duguay Walks Without a Walker as Stage 4 Cancer Fight Enters a New Treatment Phase

On August 12, Shay Thomas watched her father, Ron Duguay, walk without a walker.

For a man who spent 12 NHL seasons moving at full speed through crowded ice, the distance covered inside a rehabilitation facility may have been modest. In the context of what his body has endured over the past few weeks, however, those unaided steps carried considerably more weight.

Duguay, 69, is recovering from a frightening July collapse that left him unconscious, severely dehydrated and nursing significant facial and dental injuries. Doctors also discovered internal bleeding, varices, portal hypertensive gastropathy and an ulcer while treating a patient already living with Stage 4 colon cancer that has spread to his liver.

Now the story has moved again.

Thomas says her father has begun a new cancer treatment while continuing rehabilitation, and the family is waiting to see how his body responds and what upcoming tests reveal. She also shared perhaps the clearest physical sign of progress yet: Duguay walked without the aid of a walker.

There is still no basis for declaring that his cancer is improving, and his family has been careful not to do so. What has changed is his immediate condition. The former New York Rangers star who recently required hospitalization, blood transfusions and close monitoring is out of that acute phase, rebuilding his mobility and receiving treatment again.

After the uncertainty surrounding his late-July collapse, that qualifies as meaningful progress.

The Latest Update Is Encouraging, but It Is Not a Cancer Verdict

Thomas framed the newest development carefully. There was no declaration of remission, shrinking tumors or a dramatic medical breakthrough. Instead, she said her father had started his new treatment and that the family was waiting for upcoming testing to show how his body responds.

That distinction matters.

Cancer treatment can begin long before doctors know whether it is working. Imaging, laboratory testing and other clinical assessments normally help the treating team determine whether a therapy is controlling disease, producing a response or failing to halt progression. Duguay’s family has not publicly released such results from the new treatment.

The positive development is functional rather than oncological, at least for now.

Thomas wrote that there remains “a long road ahead,” but watching her father walk without a walker “felt huge.” Her reaction makes sense when placed against what happened less than three weeks earlier.

The Sports Encounter previously reported how Duguay’s cancer battle suddenly became a medical emergency when he lost consciousness at home on July 24.

At the time, the lost teeth provided the most visually startling evidence of the fall. The deeper concern was what doctors discovered after he reached the hospital.

The Collapse Exposed How Fragile His Physical Condition Had Become

According to his daughter, Duguay had been feeling sick and struggling to eat. By the time he collapsed, doctors found him extremely dehydrated.

Testing also identified varices, portal hypertensive gastropathy, internal bleeding and an ulcer. His family explained that cancer involving his liver, together with the effects of surgery, chemotherapy and previous liver-directed treatment, had contributed to increased pressure in and around the liver. That pressure could affect blood flow toward the stomach and contribute to bleeding.

Duguay received blood transfusions while doctors monitored him.

The fall added another layer of physical damage. Thomas later said he had lost all of his veneers and two natural teeth, while additional teeth came out after he returned home because they may have been loosened during the accident. Dental reconstruction would have to wait until his overall physical condition improved.

Yet the frightening episode did not produce the prolonged decline his family feared.

By early August he was out of the hospital, managing small amounts of food and trying to rebuild his strength. Rehabilitation followed. The latest update suggests that process is beginning to produce visible results.

Why Walking Without a Walker Really Does Matter

It would be easy to turn Duguay’s unaided steps into sports symbolism. The medical significance is more useful.

Physical rehabilitation for people undergoing cancer treatment is designed to restore movement, strength, balance and independence. City of Hope’s rehabilitation program specifically identifies difficulty walking, reduced mobility, weakness, fatigue and recovery after falls among the problems physical therapists address.

That makes Duguay’s progress relevant for reasons beyond emotion.

A patient who can walk more safely and independently has regained a degree of functional capacity after a serious setback. It does not indicate what the cancer itself is doing, but it can improve daily independence and help a patient cope with the wider physical demands of ongoing care.

Duguay’s situation is especially complicated because nutritional problems contributed to the dehydration preceding his collapse. Rebuilding strength therefore involves more than exercise. His body also needs adequate hydration and nutrition while simultaneously coping with advanced disease and treatment.

His daughter previously described him taking recovery one day at a time and trying to manage small amounts of food, including soup.

The walker milestone should be understood in that context. It represents recovery from the consequences of the medical crisis, rather than evidence that the underlying cancer has retreated.

Has Ron Duguay Started Bizengri?

This is where the latest reporting requires precision.

When Thomas announced on August 4 that her father had left the hospital, she identified Bizengri, also known as zenocutuzumab-zbco, as his planned next treatment. She described it as a targeted therapy intended to interfere with signals that can help certain cancer cells grow.

In the newer update, Thomas says Duguay has now “started his new treatment.” The publicly accessible text of that update does not explicitly repeat the name Bizengri.

It is therefore reasonable to connect the two developments as part of the same treatment plan, but The Sports Encounter cannot independently confirm from the latest public statement that the therapy he has begun is Bizengri.

That may sound like a small distinction. In a story involving experimental, targeted or off-label cancer treatment, it is an important one.

What Is Bizengri, and Why Is It Different?

Bizengri is the brand name for zenocutuzumab-zbco, a bispecific antibody designed to target HER2 and HER3 signaling associated with certain cancers carrying a genetic alteration known as an NRG1 fusion.

In simple terms, targeted cancer therapies attempt to interfere with specific biological machinery helping particular tumors grow. That differs from conventional chemotherapy, which generally attacks rapidly dividing cells more broadly.

The FDA first granted Bizengri accelerated approval in December 2024 for certain advanced NRG1 fusion-positive non-small cell lung cancers and pancreatic adenocarcinomas after prior systemic treatment. In 2026, the agency also approved it for advanced NRG1 fusion-positive cholangiocarcinoma, a cancer of the bile ducts.

The current FDA prescribing information does not list colorectal cancer among Bizengri’s approved indications.

That does not allow outsiders to determine why Duguay’s medical team considered it. Physicians can sometimes use FDA-approved drugs outside their labeled indications when they believe the scientific and clinical circumstances support doing so, while other patients may receive therapies through research or special-access mechanisms.

Duguay’s family has not publicly disclosed enough molecular information about his tumor for anyone outside his treating team to explain the precise rationale. In particular, no reliable public source reviewed by The Sports Encounter establishes that his colorectal cancer carries an NRG1 fusion.

That information belongs with his physicians unless the family chooses to make it public.

What can be reported is narrower: his daughter previously identified Bizengri as the planned next therapy, and she now says her father has begun a new treatment while the family waits for testing to reveal the response.

City of Hope Has Been Central to Duguay’s Cancer Fight

Duguay’s family has repeatedly credited his move into the care system in Orange County with stabilizing his condition after an extremely difficult earlier period in Florida.

Public accounts have identified Dr. Pashtoon Kasi as one of the physicians involved in his care. City of Hope lists Kasi as medical director of gastrointestinal medical oncology in Orange County, with expertise in colorectal cancer, gastrointestinal cancers, clinical trials, cancer genomics and precision medicine.

That background is relevant because Duguay’s treatment journey has increasingly involved individualized decisions rather than a simple, uninterrupted chemotherapy schedule.

In March, Duguay reported improved blood markers after a difficult stretch and was being evaluated for an immunotherapy clinical trial. Other public reports later documented his participation in a clinical trial before the treatment plan changed again.

His cancer has required repeated adaptation.

That is one reason the newest update should be interpreted cautiously. Starting another treatment is meaningful, but the decisive information will come later, when doctors can assess whether his disease is responding.

Ron Duguay Has Been Fighting Cancer Since 2024

The public learned about Duguay’s cancer in February 2026, but the fight had already been going on for more than a year.

His daughter has said he was diagnosed with Stage 4 colon cancer in November 2024 after experiencing fatigue and gastrointestinal discomfort. The disease had already reached his liver by the time doctors identified it.

His treatment history has included chemotherapy, surgical procedures and liver-directed care. Duguay has said he lost his appendix and gallbladder during the course of treatment, while his weight at one stage fell from approximately 210 pounds to around 170.

For an athlete whose public image had always been tied to fitness, appearance and physical confidence, the transformation was difficult to accept.

He told reporters earlier this year that part of him initially felt embarrassed because he had viewed himself as a model of good health. Eventually, that thinking changed. Duguay began talking publicly about the disease and about his own decision to avoid colon screening.

His perspective shifted toward awareness.

The Screening Message May Become the Most Important Part of His Public Legacy

Duguay has said he avoided colonoscopy because he considered the procedure invasive. After receiving a Stage 4 diagnosis, he began telling people to get their colon checked.

That message aligns with current guidance from the American Cancer Society, which recommends that adults at average risk begin regular colorectal cancer screening at age 45. People with higher-risk factors may need earlier or more frequent screening based on medical advice.

Colorectal cancer can develop without obvious early symptoms. Potential warning signs can include persistent changes in bowel habits, rectal bleeding or blood in the stool, abdominal pain, unexplained weight loss, weakness and fatigue. Those symptoms can have many causes, which is why evaluation by a healthcare professional matters.

Duguay’s experience does not prove what would have happened had he undergone screening earlier. No responsible report can reconstruct that counterfactual.

His own conclusion is simpler: he wishes he had been checked.

For a former athlete with an audience that spans generations of hockey fans, that may eventually carry more public-health value than any discussion of which treatment he receives next.

The Financial Fight Has Become Part of the Story Too

Advanced cancer care has also transformed Duguay’s finances.

His daughters Shay Thomas and Amber Stavros launched a GoFundMe after watching the physical and financial pressure grow. The family explained that Duguay could no longer work as he normally had, while regular travel between Florida and Orange County added airfare, accommodation and other expenses to treatment costs.

The campaign has attracted more than 1,000 donations and six-figure financial support.

His family initially had difficulty persuading him to accept that help. Duguay had spent much of his public life appearing at charity events and supporting other causes, which made becoming the person asking for assistance uncomfortable.

The response nevertheless shows how far his connection with hockey extends.

Sudbury, where Duguay grew up and became a junior hockey star, has rallied around him. Former opponents and teammates have reached out. NHL alumni have offered support. Rangers fans continue to follow each medical update even though his final NHL game came decades ago.

Why Ron Duguay Still Means So Much to Hockey Fans

For younger readers, the hair and photographs can make Duguay look like a cultural character from another hockey era. He was much more accomplished than the image sometimes suggests.

The New York Rangers selected him 13th overall in the 1977 NHL Draft. He scored 20 goals as a rookie and helped New York reach the 1979 Stanley Cup Final in his second NHL season.

His best Rangers year came in 1981-82, when he scored 40 goals and 76 points in 72 games and earned his only NHL All-Star selection.

He later produced even bigger numbers with Detroit, reaching 80 points in 1983-84 and a career-high 89 points the following season.

According to his official NHL record, Duguay finished with 274 goals, 346 assists and 620 points in 864 regular-season games for the Rangers, Detroit Red Wings, Pittsburgh Penguins and Los Angeles Kings.

He was never in the Wayne Gretzky or Mario Lemieux tier examined in The Sports Encounter’s ranking of the 10 greatest NHL players ever. That was never the reason New York remembered him.

Duguay represented personality at a time when hockey frequently discouraged it. He played without a helmet, wore his hair long, moved through New York celebrity culture and became recognizable outside the sport. His fame took him to Studio 54, an Andy Warhol magazine cover and mainstream advertising while he was still producing at an All-Star level.

After playing, he remained connected to Rangers fans through broadcasting, including more than a decade as an MSG Network analyst.

Hockey careers continue long after statistics stop accumulating. The Sports Encounter recently explored that idea through Jonathan Toews’ retirement after his own long health battle and through the legacies honored in the Hockey Hall of Fame Class of 2026.

Duguay occupies a different place in hockey history, but the emotional principle is similar. Fans do not stop caring about players when their careers end.

What Happens Next?

The next meaningful Ron Duguay health update will probably come from evidence rather than another dramatic event.

His family is waiting for tests to show how his body responds to the new therapy. Until those results arrive, it is impossible to say whether the treatment is controlling his cancer.

Meanwhile, rehabilitation remains important in its own right. Regaining mobility, restoring nutritional intake, avoiding another dehydration episode and recovering from the injuries caused by his fall can determine how much independence he retains during treatment.

The dental damage will also need attention once he is strong enough for further procedures.

None of those challenges is minor. Together they explain why Thomas could celebrate something as basic as walking across a rehabilitation facility without assistance.

Cautious Hope Is the Only Honest Conclusion

There is a temptation in sports writing to turn illness into another competition, complete with the familiar language of toughness, winning and refusing to lose. Cancer does not respect that vocabulary. Great athletes become sick. Determined people sometimes deteriorate. Treatments can work for reasons that have little to do with willpower, and they can fail despite extraordinary courage.

Duguay himself naturally approaches the experience with an athlete’s mentality. Earlier this summer he said that when circumstances demand it, he will fight until he drops and get back up.

The past three weeks have given that statement an uncomfortable literal meaning.

He collapsed. He went to the hospital. Doctors treated dehydration and bleeding while his family confronted another serious interruption in an already exhausting cancer journey. Now he is in rehabilitation, taking independent steps again and receiving a new treatment while doctors prepare to measure what happens next.

That is where Ron Duguay’s story stands today.

There is no evidence yet that the cancer has retreated, and there is no responsible way to predict what the new treatment will accomplish. There is, however, a meaningful difference between the frightening picture that emerged in late July and the one his daughter shared this week.

He is out of the hospital. He is rebuilding strength. Treatment has resumed. He walked without a walker.

For now, that is enough to justify hope without pretending certainty.
