Dr. Blitzer studies a range of cancer treatments, with a notable emphasis on the use of proton beam therapy and high-dose radiation techniques. He particularly investigates their applications in treating conditions like uveal melanoma, choroidal melanoma, and different forms of gynecological cancers. His research includes examining how the involvement of gynecologic oncologists can lead to better quality of care for endometrial cancer patients and analyzing surgical approaches for localized neuroblastoma in children. His work aims to provide patients with effective treatment options while minimizing side effects.
Key findings
In a study of 14 women with recurrent pelvic cancers, 86% had effective control of their cancer with an average survival time of 20.75 months using high-dose rate interstitial irradiation catheters.
Patients managed by gynecologic oncologists for endometrial cancer had a 94% rate of proper staging, compared to 45% for general gynecologists, potentially reducing unnecessary follow-up radiation.
Using three-dimensional treatment planning enhanced targeting of larynx cancer tumors and reduced harm to healthy tissue, although it increased exposure risk to surrounding areas.
In a study of 241 patients with uveal melanomas treated with proton beam therapy, 94% showed tumor shrinkage after two years, and 47% retained good vision post-treatment.
Out of 60 patients treated for choroidal melanomas, 86% exhibited tumor shrinkage after proton beam therapy, with nearly 58% maintaining good vision at follow-up.

Orr JW, Dosoretz DD, Mahoney D, Roland PY, Kelly FJ +5 more
Plain English This study looked at a new treatment method for women with persistent or recurring pelvic cancers, using special catheters to deliver high doses of radiation directly to the tumors. Out of 14 women treated, 86% had excellent control of their cancer, with an average survival of about 21 months. This approach not only showed strong results but also had few complications, making it a promising option for many women facing this kind of cancer.
Who this helps: Women with persistent or recurrent pelvic cancers.

Gynecologic oncology
Roland PY, Kelly FJ, Kulwicki CY, Blitzer P, Curcio M +1 more
Plain English This study examined how the treatment of endometrial cancer differs depending on whether patients are managed by gynecologic oncologists (GYOs) or general gynecologists (GYNs). It found that GYOs were much more thorough, completing proper staging in 94% of cases compared to 45% for GYNs, and assessed lymph nodes in 83% of cases versus 26% by GYNs. This thoroughness means that GYO patients with less advanced disease received less follow-up radiation therapy, which is important because it can reduce unnecessary treatments and associated side effects.
Who this helps: This helps women with endometrial cancer by ensuring they receive better and more tailored care.
Three-dimensional photon treatment planning in carcinoma of the larynx.

Coia L, Galvin J, Sontag M, Blitzer P, Brenner H +5 more
Plain English Researchers studied how three-dimensional treatment planning can improve radiation therapy for patients with larynx cancer. They created 30 different treatment plans for two patients and found that using 3-D imaging helped better target the tumor while minimizing harm to nearby healthy tissue. This approach showed some improvement, particularly with lower energy beams, but also increased the risk of unwanted radiation to the surrounding larynx area.
Who this helps: This benefits patients with larynx cancer by potentially improving their treatment outcomes.

Plain English Researchers studied the effects of proton beam therapy on 241 patients with uveal melanomas over 7.5 years. They found that 94% of patients with more than two years of follow-up saw their tumors shrink, and 47% had good vision afterwards (20/40 or better). This research shows that proton therapy is effective for treating different sizes of tumors without increasing the risk of cancer spreading.
Who this helps: This benefits patients with uveal melanoma and their doctors by providing an effective treatment option.
Plain English This study looked at 83 young children with localized neuroblastoma, a type of cancer, to see how different factors influenced their chances of recovery. Researchers found that certain characteristics, like the stage of the cancer and specific histology types, were key to predicting outcomes. Specifically, better surgery—when more of the tumor was removed—led to higher chances of living without the disease returning, highlighting the importance of surgical treatment in these cases.
Who this helps: This benefits young patients with neuroblastoma and their doctors by informing treatment decisions.

Plain English This study looked at the effectiveness of proton beam therapy for treating eye tumors called choroidal melanomas, particularly those close to the center of vision. Out of 60 treated eyes, 86% showed signs of tumor shrinkage after an average follow-up of 18 months, and nearly 58% had good vision (20/100 or better) at the final check-up. The results indicate that proton therapy may be a good option to save vision and avoid removing the eye, even in challenging cases.
Who this helps: This research benefits patients with choroidal melanomas who want to preserve their vision.

Plain English This study looked at 317 patients who received treatment with proton beams at the Harvard Cyclotron Laboratory for various types of cancer, including eye, head, neck, and prostate cancers. The findings were very positive, showing that treatments for choroidal melanoma and certain tumors near the brain were particularly effective, while those for prostate cancer and head and neck tumors also showed promise. These results are important because they highlight the potential benefits of using proton therapy, which may lead to improved outcomes for patients facing these challenging cancers.
