  • Yttrium 90 radioembolization for primary and metastatic liver tumors
  • Collaboration with medical oncology colleagues to optimize personalized concomitant therapies including chemotherapy, immunotherapy, and targeted molecules

We also provide Pediatric Radiation Oncology services in collaboration with colleagues at Connecticut Children’s Medical Center.


Our Multidisciplinary Team

Our multidisciplinary team includes radiation oncologists, nurses, medical physicists, dosimetrists, engineers, and radiation therapists. Collaborating closely with social workers, dietitians, and speech therapists, the team tailors optimal treatment plans for each patient and focuses on optimal support strategies for patients and family members. In addition to new patient management, the team meets regularly to focus on quality improvement, peer review, and patient satisfaction.

In a field like radiation oncology, technology moves fast. Ongoing education is imperative, and includes:

  • Participating in as many as 10 tumor conferences each week, reviewing patient cases with each site-specific team across the Cancer Institute. This is an important way we teach residents, fellows and students.
  • Mentoring the next generation of oncologists through clinical rotations with our experts. Residents and fellows, medical students, and APRN students from UCONN Medical school, Hartford Hospital Residency Programs, and other institutions learn best practices from our team.
  • Serving as a main clinical training site for the highly acclaimed Radiation Therapy Technology School. Many of our physicians, physicists, dosimetrists and staff also lecture at the school.

More Treatment Options for Patients

The depth and breadth of our radiation oncology services means we can offer patients more treatment options.

Prostate Cancer

Intensity modulated radiation therapy (IMRT) is the hallmark external beam treatment, combined with daily image guided radiation that assures highly accurate positioning of the treatments. IMRT can usually be delivered with conventional fractionation over 8-9 weeks or over 5.5 weeks with moderate hypofractionation. We are also conducting research on ultra-hypofractionation using stereotactic body radiation therapy with 5 fractions over 1.5 weeks in highly selected cases.We also offer several brachytherapy options for prostate cancer patients. These include low dose rate (LDR) permanent seed implants of Pd-103 or I-125 seeds, either as monotherapy or in combination with IMRT, or high dose rate (HDR) temporary implants with Ir-192 in combination with IMRT. Temporary seed implant programs are an alternative for selected patients whose glands are too large for permanent seed implantation or for whom seed implantation is not appropriate. With Temporary High-Dose Rate brachytherapy seed implant, we use CT imaging to guide placement of catheters into the prostate through the perineum. Through the catheters, we deliver homogeneous doses of high activity iridium-192 seed in two 15-30 minute treatment applications. Patients stay in the hospital for just two days, and then usually have five weeks of external irradiation to the prostate and surrounding tissues.

In selected prostate cancer cases, we enhance the radiation effectiveness by combining it with androgen deprivation therapy.

Breast Cancer

Treatments are always personalized to each patient's situation, using the most innovative practices in radiation oncology. For instance, we routinely use deep inspiration breath hold (DIBH) techniques for appropriate patients with left breast cancer. We have adopted this best practice to avoid exposing patients' heart tissue to potentially damaging radiation.

In many cases we can now deliver external breast radiation therapy in three to four weeks, much shorter than the traditional daily treatments over 6 weeks. We also offer partial breast irradiation when possible, delivered straight to the lumpectomy region. This technique uses a balloon catheter with HDR brachytherapy twice daily for 5 days (10 treatments). Lymph node radiation to the axilla, supraclavicular area, and internal mammary area, is also provided in selected cases. IMRT approaches are also available for selected patients to treat nodal tissue while avoiding heart and lung tissues.

Lung Cancer

Our radiation oncology team is very experienced with stereotactic body radiation therapy (SBRT), often used to treat small lung cancers with no lymph node involvement. This highly-targeted treatment can be delivered in 3-5 fractions over 1-1.5 weeks, and minimizes normal lung tissue exposure to potential radiation injury.

More advanced breast cancers are often treated with radiation in combination with chemotherapy. Some patients need radiation before surgery to shrink their tumor, or after surgery to eradicate residual microscopic disease. We also routinely use 4D CT simulation to monitor radiation targets and avoidance injuring normal tissues that move during the respiratory cycle.

Gastrointestinal Cancer

Certain gastrointestinal cancers (rectal cancer, esophageal cancer, and pancreatic cancer) need treatment with a combination of chemotherapy and radiation before they can be surgically removed. In some cases we use a combination of chemotherapy and radiation therapy after surgery, or even as a definitive treatment alternative to surgery.

Liver Cancer

Hartford HealthCare's liver cancer program includes physicians and staff from the organ transplant program, interventional radiology, hepatobiliary surgery, medical oncology, and radiation oncology disciplines. This comprehensive multidisciplinary approach enables us to offer patients with liver tumors the entire gamut of liver directed and systemic therapies for primary or metastatic disease. Radiation therapy approaches include external radiation therapy to isolated lesions with stereotactic body radiation therapy (SBRT), or infused Y90 radioembolization with SIR spheres for selected patients in collaboration with interventional radiology.

Head and Neck Cancer

We work closely with all members of the multidisciplinary team including head and neck surgery, medical oncology, dentistry, oral surgery, speech therapy, dietary, research and nursing to develop an appropriate tailored plan for each patient. IMRT and IGRT with concomitant chemotherapy are frequently used to treat tumors and minimize normal tissue exposure and other acute and late effects of treatment. All patients are surrounded by a very supportive team during treatment.

Brain Tumors

We are actively involved in the Neuro Oncology multidisciplinary team which includes neurosurgeons, neurologists, medical oncologists, neuroradiologists and neuropathologists. Treatments include IMRT, stereotactic radiosurgery (single treatment) and stereotactic radiation therapy (2-5 treatments). This highly sophisticated therapy features accurate positioning confirmed by state of the art ExacTrac X-ray monitoring. We often combine this therapy with chemotherapy.

Gynecologic Cancer

Our radiation oncologists use advanced techniques to maximize gynecologic cancer treatments and minimize side effects. Our experienced specialists use both external beam radiation therapy (3D conformal, IMRT, IGRT) and internal radiation (brachytherapy) to manage gynecologic cancers including endometrial cancer, cervical cancer, vaginal cancer, and vulvar cancer.
