Treatment Philosophy
I first had the opportunity to treat patients with sarcoma during my oncology fellowship training. I really enjoyed the challenge of this area of oncology because of the many types of tumors and their rarity. When I meet a patient, I work to be certain the pathologic diagnosis is correct and address what we need to do to treat the disease. I collaborate with Fox Chase pathologists, radiologists, surgeons, radiation oncologists and social workers to develop the right treatment plan. We meet as a team weekly at the Sarcoma multi-disciplinary tumor board to review individual patient cases and agree on the best management.
I am also committed to developing new therapies for patients with sarcomas. The strides made in improving cancer care have come from research and clinical trials. I work closely with scientists to better understand gastrointestinal stromal tumors and other sarcomas. I aim to have research studies as a treatment option for my sarcoma patients.

Larry Reddick
Larry Reddick
In the fall of 2015, Larry Reddick, 74, was becoming increasingly frustrated with his hoarse voice. It was difficult to speak and his voice quality continued to get worse. He also began to lose weight without trying. “I had a hunch something wasn’t right so I called my primary doctor to get a referral to see an ear, nose and throat (ENT) specialist. Unfortunately, I didn’t find my local ENT helpful,” recalls Larry.
Michelle Palandro
Michelle Palandro
In the spring of 2011, Michelle Palandro noticed a hard bump on her hip so she had her doctor check it out. The doctor ordered an X-ray which showed “fatty tissue in normal limits.” She followed her doctor’s recommendation and didn't worry about it, especially because she was so healthy and active. Then in July, after a moderate mountain hike, she developed excruciating pain in her lower leg. She went to a general surgeon to have the growth removed the following month. Tests revealed she had malignant stage 3 liposarcoma, a type of tumor that grows within the fat cells in deep soft tissue.

Robert Smith
Robert Smith
Robert W. Smith’s story has a happy ending, but began with fear and uncertainty. In 1998, almost out of the blue, he noticed a lump on the side of his torso. “I was 54 and healthy, and I just felt this lump,” he recalls. He went to a community hospital where doctors ordered testing. The pathology report confirmed that Bob had fibrous spindle cell sarcoma.
Robert Crossfield
Robert Crossfield
In the summer of 2007, Robert Crossfield was digging a trench for new drain line outside of his home. When he finished, his wife Joan noticed a lump on the right side of his chest through his tank top. As a father of five boys, including triplets, this 30-year Philadelphia fireman was concerned about the lump and made an appointment with his primary doctor.
