Background: Radium-223 (Ra-223) radioisotope has been reported to increase median survival in bone metastatic prostate carcinoma. The addition of Ra-223 to abiraterone was associated with an increased risk of bone fractures. There has been no comprehensive data for using Ra-223 in veterans who were exposed to Agent Orange (AO+).

Purpose: To identify factors that condition or moderate the impact of a previously described set of interventions on psychological and physical adjustment after diagnosis and treatment for early-stage breast cancer.

Patients And Methods: Younger women (age < 51 years, N = 252) with early-stage breast cancer within 2 months of having completed active nonhormonal adjuvant therapy were randomly assigned to a three-arm clinical trial, consisting of a control arm, an education arm, and a nutrition arm. Primary end points, assessed before random assignment and 4 and 13 months later, included mental functioning, physical functioning, and depressive symptoms.

Breast, chest wall, and regional nodal irradiation have been associated with an improved outcome in high-risk breast cancer patients. Complex treatment planning is often utilized to ensure complete coverage of the target volume while minimizing the dose to surrounding normal tissues. The 2 techniques evaluated in this report are the partially wide tangent fields (PWTFs) and the 4-field photon/electron combination (the modified "Kuske Technique").

Skin doses from brachytherapy using MammoSite HDR, Intensity Modulated Radiation Therapy (IMRT), and conventional tangential fields techniques were compared. For each treatment technique, skin doses were measured using paired thermoluminescent dosimeters placed on the patient's skin: (i) directly above the balloon catheter during MammoSite HDR brachytherapy treatments and (ii) 4 cm inside the treatment borders during the IMRT and conventional breast treatments. The mean dose measured was about 58% of the prescription dose for the patients treated using the MammoSite technique.

Purpose: The study aimed to assess the outcome of locally advanced cervical and vaginal cancer treated with high-dose-rate interstitial brachytherapy (HDRB).

Methods And Materials: Between 1998 and 2004, 16 previously unirradiated patients with locally advanced cervical and vaginal cancer not suitable for intracavitary brachytherapy because of distorted anatomy or extensive vaginal disease were treated with HDRB in combination with external beam radiotherapy. All patients received whole pelvis external beam radiation therapy (EBRT) followed by interstitial implantation.

Objective: To assess kidney function via creatinine clearance before and after radiotherapy in gynecologic cancer patients treated to the para-aortic (PA) area via Intensity Modulated Radiotherapy (IMRT).

Methods: Twenty-three patients underwent IMRT to the para-aortic area, were followed for at least 5 months, and had the necessary laboratory data to calculate creatinine clearance. Various patient-related factors and radiotherapy-treatment related factors were analyzed to determine their association with changes in CrCl.

Purpose: To measure respiration-induced abdominal organ motion using four-dimensional computed tomography (4D CT) scanning and to examine the organ paths.

Methods And Materials: During 4D CT scanning, consecutive CT images are acquired of the patient at each couch position. Simultaneously, the patient's respiratory pattern is recorded using an external marker block taped to the patient's abdomen.

Objective: To assess local control and chronic toxicity with IMRT for adjuvant treatment of endometrial carcinoma.

Methods: Forty-seven patients with endometrial cancer were treated with adjuvant IMRT and HDR brachytherapy (HDRB). The external beam dose was between 45 and 50.

Purpose: Medically inoperable patients with uterine cancer pose a therapeutic challenge. We developed a twice-daily schedule of high-dose-rate brachytherapy (HDRB) after a single insertion procedure that required a hospitalization of 3 days.

Methods And Materials: Favorable patients were offered brachytherapy alone, and all other patients received HDRB after pelvic external beam radiation therapy (EBRT).

Objectives: To assess the acute tolerance of delivering concurrent cisplatin and extended field radiotherapy (EFRT) using intensity-modulated radiotherapy technique (IMRT) for cancer of the cervix.

Methods: All patients receiving definitive treatment for cervical cancer were treated with EFRT using IMRT technique and concurrent cisplatin. The treatment volume included the cervix, uterus, parametria, presacral space, upper vagina, pelvic, common iliac, and paraaortic nodes to the top of L1.

Objective: To evaluate outcomes in cervical cancer patients treated with high-dose-rate (HDRB) or low-dose-rate (LDRB) brachytherapy.

Methods: A retrospective chart review compared control rates, survival, and complications in the two groups.

Results: All patients received pelvic EBRT (45 Gy/5 weeks).

Objectives: To assess early clinical outcome of intensity-modulated radiation therapy (IMRT) in the treatment of vulvar cancer and compare dosimetric parameters with 3D conformal radiotherapy (3D CRT).

Methods: Fifteen patients with vulvar cancer were treated with IMRT. Seven patients were treated with preoperative chemoradiation, and 8 patients were treated with adjuvant postoperative radiation therapy.

Objective: A twice daily (BID) radiation treatment schedule (interval of 4-6 h) delivered concurrent with chemotherapy for advanced or critically located carcinoma of the vulva was modeled on the schema developed by the Gynecology Oncology Group (GOG). Inguinal nodes were included in the treatment fields even if clinically negative. This review analyzed the outcomes using this approach.

Purpose: To conduct a clinical trial to determine if an educational intervention and a nutritional intervention could enhance physical and psychological functioning among younger women completing treatment for early-stage breast cancer.

Patients And Methods: Younger women (50 years of age or younger, N = 252), within 2 months of having completed active nonhormonal adjuvant therapy, diagnosed with stage 0, I, or II breast cancer with 10 or fewer positive lymph nodes were randomly assigned to a three-arm clinical trial. Women in the control arm of the trial received standard medical care.
