Regardless of residence, nearly 25% of patients with cancer overall miss at least 10% of the doses in their radiation treatment plans—but the implications on outcomes are far greater for patients living in rural areas than their urban counterparts, according to new research findings published in the International Journal of Radiation Oncology, Biology, Physics.

November 7, 2022, is the 155th birthday of Maria Sklodowska, who is better known as Madame Marie Curie, one of the greatest minds of chemistry, physics, and radiation oncology. The day also marks the fifth anniversary of #WomenWhoCurie, a social media campaign from the Society for Women in Radiation Oncology that supports and increases visibility of women in radiation oncology.

Sally is a 65-year-old patient with T3N1M0 human papillomavirus–negative cancer of the supraglottic larynx who is beginning treatment with radiation and chemotherapy. She has a history of type 1 diabetes mellitus, diabetic retinopathy, diabetic nephropathy, and hospital admissions for diabetic ketoacidosis. She has been using a continuous glucose monitor and insulin pump to help her effectively manage her diabetes. She is concerned that her chemotherapy regimen will involve taking dexamethasone, which will affect her hard-to-control diabetes. Sally tells you she wants to wear her CGM and IP during treatment.

Immunotherapy has revolutionized cancer treatment, especially for patients with diseases considered otherwise incurable. Since May 2017, the U.S. Food and Drug Administration (FDA) has approved 27 immunotherapy combinations, including chemoimmunotherapy and regimens with targeted therapies, and researchers are reporting highly promising data from clinical trials of its combination with radiation.

More than 90% of patients report that telehealth consultations during radiotherapy treatment are high quality and may be even better for understanding information from their healthcare team than in-person visits, researchers reported in the Journal of the National Comprehensive Cancer Network.

Bob is a 68-year-old patient with early-stage cancer of the glottic larynx (right true vocal cord). He is receiving a hypofractionated three-dimensional conformal therapy without concurrent chemotherapy, 225 cGy each day for five days a week to a total dose of 6,075 cGy. He is now in his fourth week of treatment at 4,000 cGy and experiencing side effects. His voice is a high-pitched whisper and talking requires a lot of effort. He reports pain when swallowing his favorite foods like nachos and has lost 2 kg since his last weight check four days ago. Bob also reports some dizziness with position changes, and his pulse and blood pressure screenings show that he’s mildly orthostatic.

Initially studied for its radioprotective effects on healthy cells, avasopasem may also increase cancer cells’ response to radiation treatment, researchers reported in Science Translational Medicine.

Palliative radiation targeted directly to the tumor with stereotactic body radiation therapy eliminated metastatic pain in 33% of patients for six months compared to 16% with standard radiation therapy. Researchers reported the study findings at the American Society for Radiation Oncology annual meeting.

Sharon is a 60-year-old woman with metastatic breast cancer that was originally diagnosed in 2005 and treated with a mastectomy, deep inferior epigastric artery perforator flap reconstruction, chemotherapy, post mastectomy radiation, and five years of tamoxifen. Three months ago, her breast cancer recurred, and staging scans demonstrated metastatic disease in the lungs, left axilla, liver, and left iliac bone. A biopsy of the left iliac bone was ER positive, PR negative, and HER2 negative. Sharon began treatment with radiation to the painful left hip and letrozole, with the plan to start palbociclib once radiation was completed. 

Prostate cancer is one of the most common cancers treated with radiotherapy (RT). Conventional RT for low-risk patients usually involves 40–45 treatments given over eight or nine weeks. Several studies suggest that hypofractionated RT—fewer treatments but with a higher dose per treatment—may produce a similar survival benefit. When two treatments have similar survival outcomes, the decision process looks at symptom profiles, quality of life, and cost.

Radiation therapy (RT) has been used as a safe and effective treatment option for patients with cancer for more than a century. Like any cancer therapy, it does carry risks and side effects, but RT has improved drastically over the past 20 years and has even been shown to enhance the effectiveness of immunotherapy.

Included in the treatment plan for approximately 50% of all patients with cancer, radiotherapy (RT) is a significant component of cancer care. RT is a technology-driven oncology modality, which means it has continually evolved since being introduced in cancer care in the early 20th century.

Women receiving pelvic radiation therapy for gynecologic cancers are at higher risk for significant decreases in bone mineral density (BMD), with 7.8% of women in the study diagnosed with a pelvic fracture, according to findings from a study published in Cancer.

Proton beam radiation therapy is safer and equally effective as traditional radiation for adults with advanced cancers, researchers reported in study findings in JAMA Oncology.

The abscopal effect is a unique phenomenon in cancer treatment that occurs when radiation shrinks untreated tumors found elsewhere in the body in addition to the targeted tumor. The effect has a long history, dating back to the 1950s, but it doesn’t commonly occur in practice and the mechanisms are not fully understood. Research has shown that combining immunotherapy with radiation increases the rate at which the abscopal effect occurs. Understanding how it appears in practice could potentially lead to new cancer treatments and a novel approach to combining immunotherapies with radiation.

The Adjuvant Radiotherapy Intensification Classifier (ARTIC) predicts which women with early-stage breast cancer will benefit the most from radiotherapy, as well as their risk for locoregional recurrence after radiation, researchers reported in study findings published in the Journal of Clinical Oncology. 

Children with acute lymphoblastic leukemia (ALL) at risk for cancer recurrence in the brain don’t need prophylactic radiation therapy, researchers reported in the Journal of Clinical Oncology. 

Global radiation oncology research has seen an increased commitment to addressing disparities in the world and at home. The more radiation oncology proves and improves itself as a therapeutic modality, the more we are faced with the reality that the odds for survival are related to geography, poverty, education, and race.

Patients receiving hypofractionated external-beam radiation therapy (EBRT) for early-stage prostate cancer experienced similar outcomes and toxicities as those receiving standard radiation at lower doses over a longer period of time, the American Society for Radiation Oncology, American Society of Clinical Oncology, and American Urological Association say in a new clinical guideline.

Which of the Following Represents the Rate of Radioactive Decay Equal to One Disintegration per Second?

Nurse practitioners provide quality and value in radiation oncology clinics. By managing the effects of radiation during and after treatment, as well as following patients into survivorship, nurse practitioners are continually improving the quality of care that patients receive during and following treatment.

Misconceptions about radiation treatments, associated side effects, and impact on patient care still permeate medical oncology for patients and providers alike. As educators, patient advocates, and caregivers, radiation oncology nurses play a critical role in the successful treatment and support of patients with cancer.

Radiation therapy is a precise cancer treatment that targets tumor cells specifically and spares healthy surrounding tissues. Contrary to pharmacologic treatment methodologies, side effects are predominantly site-specific.
