STAMFORD — Frank Colandro has thrown some crazy parties in his day. He’s done Hawaiian luaus, traveling keg parties that got him kicked out of all corners of Stamford — even a celebration of his divorce.

On Saturday, Colandro continued his wild tradition with a disco-themed soirée to mark more than a year cancer-free.

The 58-year-old stopped short of wearing bell-bottoms and platform shoes. But he had tie-dye shirts, a shimmering disco ball and hula hoops for the 200 guests who descended on his North Stamford home.

“I went a little overboard,” he said over the phone just days before, in between directing a delivery of tables and chairs. “But the more, the better, in my eyes.”

In some respects, Colandro applied this principle to attacking his non-Hodgkin lymphoma. He fought hard and was open to trying an experimental treatment that despite nearly killing him, may end up saving his life.

Many people know Colandro from his Darien deli, Mama Carmela’s. It was there eight years ago that a customer who was a physician’s assistant spotted a lump behind Colandro’s right ear that he had put off getting checked. The customer pushed him to finally see a doctor.

“I got the phone call the Monday before Thanksgiving. I didn’t expect to hear cancer and then I didn’t tell anybody in my family, and they got pissed off,” he said. “Why ruin everyone’s holiday? It wasn’t going to help anybody, me telling them before.”

Colandro sought treatment with Dr. Steve Lo, an oncologist at Stamford Hospital’s Bennett Cancer Center who started him on chemotherapy. For the type of B-cell lymphoma Colandro has, Lo prescribed a chemo cocktail called CHOP, which Colandro explained is an acronym for “the kind of poisons they’re putting in you.”

It was a powerful treatment that cost Colandro his hair — once it started falling out he and his 10 nieces and nephews shaved it off together — but bought him nearly two years in remission.

Two weeks shy of the two-year mark, the point at which the odds of the cancer returning are greatly reduced, Colandro learned it was back.

He went through more chemotherapy. After sitting for hours under an IV drip, he would often return to the deli for 10 or 12 hours.

Around that time another customer told Colandro about an experimental cancer treatment called CAR-T therapy, which described sounds impossibly futuristic.

It involves extracting immune system T-cells from a patient’s blood, sharpening the cells’ ability to spot and kill cancer by altering their DNA and injecting them back into the patient.

CAR-T therapy is believed to be effective for patients battling advanced lymphoma and leukemia, but it’s not without serious side effects. The latter part of the treatment causes the immune system to go haywire, resulting in extreme flu-like symptoms. It can also damage the brain, causing memory loss and hallucinations.

For Colandro, who by that time had developed a dozen tumors across his body, including one pressed up against his esophagus that made it difficult to eat and breathe, the risks were worth it.

“I could barely control his disease month by month. That’s how precarious it was,” Lo said.

Colandro was the first lymphoma patient accepted into a clinical trial for CAR-T therapy through the Dana-Farber Cancer Institute and Brigham and Women’s Hospital in Boston.

The treatment nearly killed him. Colandro’s white blood cell count dropped dangerously low. He developed an outbreak of the shingles virus on his face. Little else from that time he remembers.

Within days of the infusion, the tumors on his spleen, stomach and elsewhere had nearly disappeared.

Colandro has been in remission since February 2016.

“He’s one tough guy,” Lo said. “Hopefully, his immune system has learned how to keep him well and keep this under control. Without this experimental therapy, I don’t think he would be alive.”

Colandro was driving home recently and thinking about his first party in more than 10 years when a song by one of his favorite groups, the Bee Gees’ “Stayin’ Alive,” came on the radio — a fitting anthem for his cancer battle. Right then, Colandro’s ’70s theme was born.

“I’m strong mentally, even though I’m a cry baby,” he said. “I always said to myself from day one this isn’t going to take me down.”
