Radiation Oncology

Spectrum Healthcare Partners Radiation Oncology

If radiation therapy is part of your cancer treatment, it’s reassuring to know that, through our partnership with Maine Medical Center’s Cancer Institute, Spectrum Healthcare Partners offers today’s most advanced radiation oncology care at four convenient locations in Portland, Scarborough, Bath and York County.

Each year, our board-certified and fellowship-trained experts deliver over 30,000 treatments to adults and children—making us the most experienced radiation oncology team in Maine.

We’re also the only radiation oncology group in the state that’s a member of the Radiation Therapy Oncology Group (RTOG). RTOG is a national cooperative group, funded by the National Cancer Institute (NCI), that conducts radiation therapy research and clinical trials to improve survival and quality of life for cancer patients.

This means we can offer you truly cutting-edge treatments and investigational protocols that aren’t available anyplace else in this region—tailored to your unique situation.

The conditions we treat with radiation therapy

Spectrum’s radiation oncologists treat adults and children with all types of cancer, including:

  • Bone cancer
  • Brain tumors
  • Breast cancer
  • Gastrointestinal cancer
  • Genitourinary cancer
  • Head and neck cancer
  • Lung Cancer
  • Metastatic cancer
  • Non-Hodgkins and Hodgkins lymphomas
  • Oral cancer
  • Pediatric cancers
  • Prostate cancer
  • Skin cancers

We also use radiation therapy to treat benign (non-cancerous) conditions such as:

  • Heterotopic bone formation (extra bone growth after joint replacement surgery)
  • Vascular conditions to reduce the possibility of repeated blockage (restenosis) of a blood vessel
  • Keloids (fibrous growths on the skin) 

The types of radiation therapy we offer

Spectrum’s radiation oncology team offers a full range of today’s most advanced types of radiation therapy, including:

The most common type of radiation therapy used for cancer treatment, external beam radiation uses a machine (called a linear accelerator) to aim high-energy radiation beams from outside the body into the tumor to destroy cancer cells.

  • 3-dimensional conformal external beam radiation therapy enables us to deliver a higher dose of radiation to a tumor with less damage to the surrounding healthy tissue
  • Intensity modulated radiation therapy (IMRT) is a type of conformal EBRT that uses computer-generated images to show the size and shape of a tumor. The radiation oncologist can then more precisely shape the beam to the tumor and vary its intensity, reducing damage to nearby healthy tissue.
  • Image-guided radiation therapy (IGRT), the most advanced form of radiation therapy, combines image-guided accuracy with intensity modulated precision, ensuring that radiation targets the tumor and spares nearby healthy tissue
  • Stereotactic radiosurgery is a non-invasive way to treat brain tumors without the risks of surgery. Despite its name, radiosurgery isn’t actual surgery, but a radiation therapy technique that uses extremely precise equipment and 3-dimensional computer planning to focus a beam of high-dose x-rays on a brain lesion.

This is a type of radiation therapy in which radioactive material is placed directly into or near a tumor. It’s also called implant radiation therapy or internal radiation therapy.

  • High-dose rate (HDR) brachytherapy is a technique that delivers a higher dose of radiation in a shorter period. This therapy can be used alone or to boost standard EBRT. We were the first in Maine to perform HDR brachytherapy.
  • Accelerated Partial Breast Irradiation (APBI) is a form of HDR brachytherapy that can shorten radiation therapy for early-stage breast cancer from the standard 6 to 7 weeks of treatment to just 1 week in appropriate patients. APBI involves twice-daily outpatient treatments over a 5-day period, versus daily visits over a six-week period for conventional, whole-breast EBRT.
  • Low-dose rate (LDR) brachytherapy: Sometimes called permanent seed implants, this technique uses tiny radioactive seeds that are implanted, usually in the prostate. The seeds emit low levels of radiation over several weeks, eventually becoming harmless. They are left in place permanently. LDR brachytherapy is primarily used to treat early-stage prostate cancer.

Radiation therapy for children

Spectrum’s radiation oncologists have undergone specialized training in delivering radiation therapy to children and young adults. We use the latest technologies and techniques to safely destroy cancer cells while sparing normal, healthy tissue.

In coordination with the Maine Children’s Cancer Program, each year we treat over 60 children with cancer. As part of a network that includes Boston Children’s Hospital, Dana Farber Cancer Institute, and the Children’s Oncology Group, we have access to the latest research and clinical trials—for each child’s optimal care.

A commitment to the highest-quality cancer care

Spectrum is Maine’s only radiation oncology practice that’s part of the National Comprehensive Cancer Network (NCCN), an alliance of 28 U.S. cancer cancers that have earned NCI designation for the thoroughness of their care. This demonstrates our commitment to complete, effective and compassionate cancer care.

In addition, our practice sites are accredited by the American College of Radiology (ACR), so you know we’ve met rigorous national standards for quality and safety.
