Abstract
BACKGROUND To compare patterns-of-care and clinical outcomes among uninsured versus insured patients (IPs) with anorectal malignancies referred for radiotherapy at an urban safety-net hospital. This topic is important because uninsured patients (UPs) in the US often have limited access to health care, which can result in worse health outcomes. METHODS We reviewed the medical records of 59 patients with biopsy-proven, non-metastatic anal and rectal cancers who received curative-intent primary or neoadjuvant/adjuvant radiotherapy between May 2002 and August 2012. Data regarding patient and disease characteristics, weight loss, insurance status at symptom onset, date of first therapeutic intervention, and survival status at last follow-up, were collected and analyzed. RESULTS The percentage of IPs presenting with T4 tumors was 7% versus 40% among the uninsured (P=0.005). The median interval between first symptom onset and diagnosis date was 89 (range, 0-1,428) days for IPs and 221 (range, 0-1,576) days for UPs (P=0.01). The median interval between first symptom onset and treatment initiation was 172 (range, 9-1,498) days for IPs and 302 (range, 35-1,624 days) days for UPs (P=0.01). The 5-year overall survival rate was 59% for the entire cohort, 62% for the insured patients, and 55% for the uninsured patients (P=0.76). CONCLUSIONS Differences in health insurance status demonstrated various disparities in patterns-of-care, including significant delay in diagnosis, more advanced-stage disease at presentation, and treatment initiation delays among UPs. Nevertheless, overall survival at 5 years was not statistically significant between the insured and the uninsured.

Abstract
OBJECTIVE Compared with radical resection alone, perioperative radiation therapy (RT) combined with neurovascular preserving surgery is the standard for the management of virgin soft-tissue sarcomas. Yet, the optimal management of a local recurrence remains unclear. We report outcomes of patients with locally recurrent soft-tissue sarcoma treated with resection and reirradiation at the University of Florida. MATERIALS AND METHODS We reviewed the records of patients treated with primary conservative surgery and radiation for soft-tissue sarcoma followed by salvage resection and reirradiation for a local recurrence at our institution. RESULTS We analyzed 23 patients treated between 1976 and 2014 (median follow-up, 46 mo). Tumor sites included: proximal extremity, 11 patients; trunk, 6; distal extremity, 5; and head and neck, 1. All patients had conservative gross total resection of their recurrent tumor, without amputation. For reirradiation, 16 patients received external-beam RT alone, 6 received external-beam RT and brachytherapy, and 1 received brachytherapy alone. Two patients received chemotherapy. After retreatment, the 5-year overall survival, cause-specific survival, local control, and distant control rates were 39%, 42%, 46%, and 60%, respectively. Ten patients experienced local recurrences, 1 experienced regional recurrence, and 9 developed distant metastases. Retreatment-related complications ranged from delayed wound healing to limb amputation; 8 patients required amputation. Only 3 patients remained disease-free at last follow-up. No statistically significant associations were found between treatment factors (eg, RT dose) and local control. CONCLUSIONS Achieving local control of recurrent soft-tissue sarcoma is challenging. Treatment with reoperation and reirradiation can lead to debilitating complications affecting function and quality of life.

Abstract
Purpose Postprostatectomy radiation improves disease control, but limited data exist regarding outcomes, toxicities, and patient-reported quality of life with proton therapy. Method and Materials The first 102 patients who were enrolled on an outcome tracking protocol between 2006 and 2017 and treated with double-scattered proton therapy after prostatectomy were retrospectively reviewed. Eleven (11%) received adjuvant radiation, while 91 (89%) received salvage radiation. Seventy-four received double-scattered proton therapy to the prostate bed only. Twenty-eight received a double-scattered proton therapy prostate-bed boost after prostate-bed and pelvic-node treatment. Eleven adjuvant patients received a median dose of 66.6 GyRBE (range, 66.0-70.2). Ninety-one salvage patients received a median dose of 70.2 GyRBE (range, 66.0-78.0). Forty-five patients received androgen deprivation therapy for a median 9 months (range, 1-30). Toxicities were scored using Common Terminology Criteria for Adverse Events v4.0 criteria, and patient-reported quality-of-life data were reviewed. Results The median follow-up was 5.5 years (range, 0.8-11.4 years). Five-year biochemical relapse-free and distant metastases-free survival rates were 72% and 91% for adjuvant patients, 57% and 97% for salvage patients, and 57% and 97% overall. Acute and late grade 3 or higher genitourinary toxicity rates were 1% and 7%. No patients had grade 3 or higher gastrointestinal toxicity. Acute and late grade 2 gastrointestinal toxicities were 5% and 2%. The mean values and SDs of the International Prostate Symptom Score, International Index of Erectile Function, and Expanded Prostate Cancer Index Composite bowel function and bother were 7.5 (SD = 5.9), 10.2 (SD = 8.3), 92.8 (SD = 11.1), and 91.2 (SD = 6.4), respectively, at baseline, and 12.1 (SD = 9.1), 10.1 (SD = 6.7), 87.3 (SD = 18), and 86.7 (SD = 13.8) at the 5-year follow-up. Conclusion High-dose postprostatectomy proton therapy provides effective long-term biochemical control and freedom from metastasis, with low acute and long-term gastrointestinal and genitourinary toxicity.

Abstract
We updated the University of Florida experience treating head and neck small cell carcinoma. Eight patients received a median of 67.7 Gy between 1989 and 2017. The 2-year rates of local, regional, distant, and disease control were 73, 60, 33, and 13%, respectively. The 2-year overall survival rate was 38%; median survival was 1.4 years. The longest disease-free period was 9.5 years after treatment with no evidence of disease. Radiotherapy is an acceptable treatment for these patients, who tend to have poor outcomes and distant metastatic disease. Superior systemic chemotherapy may improve outcomes and decrease the likelihood of distant recurrence.

Abstract
Purpose Due to the excellent outcomes with image-guided stereotactic body radiotherapy for patients with early-stage non–small cell lung cancer (NSCLC) and the low treatment-related toxicities using proton therapy (PT), we investigated treatment outcomes and toxicities when delivering hypofractionated PT. Materials and Methods Between 2009 and 2018, 22 patients with T1 to T2 N0M0 NSCLC (45% T1, 55% T2) received image-guided hypofractionated PT. The median age at diagnosis was 72 years (range, 58-90). Patients underwent 4-dimensional computed tomography simulation following fiducial marker placement, and daily image guidance was performed. Nine patients (41%) were treated with 48 GyRBE in 4 fractions for peripheral lesions, and 13 patients (59%) were treated with 60 GyRBE in 10 fractions for central lesions. Patients were assessed for CTCAEv4 toxicities with computed tomography imaging for tumor assessment. The primary endpoint was grade 3 to 5 toxicity at 1 year. Results The median follow-up for all patients was 3.5 years (range, 0.2-8.8 years). The overall survival rates at 3 and 5 years were 81% and 49%, respectively. Cause-specific survival rates at 3 and 5 years were 100% and 75%, respectively. The 3-year local, regional, and distant control rates were 86%, 85%, and 95%, respectively. Four patients experienced in-field recurrences between 18 and 45 months after treatment. One patient (5%) developed a late grade 3 bronchial stricture requiring hospitalization and stent. Conclusion Image-guided hypofractionated PT for early-stage NSCLC provides promising local control and long-term survival with a low likelihood of toxicity. Regional nodal and distant relapses remain a problem.

Abstract
BACKGROUND The treatment of centrally-located early-stage non-small cell lung cancer (NSCLC) with image-guided stereotactic body radiotherapy (SBRT) is challenging due to the proximity of critical normal structures to the tumor target. The purpose of this study was to report the results of our experience in treating centrally-located early-stage NSCLC with hypofractionated proton therapy (PT). MATERIAL AND METHODS Between 2009 and 2018, 23 patients with T1-T2N0M0 NSCLC (T1, 46%; T2, 54%) were treated with image-guided hypofractionated double-scattering PT. The median age at the time of treatment was 74 years (range, 58-88). Patients underwent 4-dimensional computed tomography (CT) simulation following fiducial marker placement, and daily image guidance was performed. All patients were treated with 60 GyRBE in 10 fractions. Patients were assessed for CTCAEv4 toxicities weekly during treatment, and at regular follow-up intervals with CT imaging for tumor assessment. Overall survival, cause-specific survival, local control, regional control, and metastases-free survival were evaluated using cumulative incidence with competing risks. RESULTS Median follow-up for all patients was 3.2 years (range, 0.2-9.2 years). Overall survival rates at 3 and 5 years were 81% and 50% (95% CI, 27-79%), respectively. Cause-specific survival rates at 3 and 5 years were 81% and 71% (95% CI, 46-92%). The 3-year local, regional, and distant control rates were 90%, 81%, and 87%, respectively. Three patients (13%) experienced local recurrences as their first recurrence, at a median time of 28 months from completion of radiation (range, 18-61 months). Two patients (9%) experienced late grade 3 toxicities, including 1 patient who developed a bronchial stricture that required stent placement. CONCLUSION Image-guided hypofractionated PT for centrally-located early-stage NSCLC provides excellent local control with low rates of grade ≥3 toxicities. For tumors in sensitive locations, PT may provide safer treatment than photon-based treatments due to its dosimetric advantages.

Abstract
PURPOSE Despite the dosimetric advantages of proton therapy, little data exist on patients who receive proton therapy for Ewing sarcoma of the cranium and skull base. This study reports local disease control and toxicity in such patients. MATERIALS/METHODS We reviewed 25 patients (≤21 years old) with nonmetastatic Ewing sarcoma of the cranium and skull base treated between 2008 and 2018. Treatment toxicity was graded per the Common Terminology Criteria for Adverse Events v4.0. The Kaplan-Meier product limit method provided estimates of disease control and survival. RESULTS Median patient age was 5.9 years (range, 1-21.7). Tumor subsites included the skull base (48%), non-skull-base calvarial bones (28%), paranasal sinuses (20%), and nasal cavity (4%). All patients underwent multiagent alkylator- and anthracycline-based chemotherapy; 16% underwent gross total resection (GTR) before radiation. Clinical target volume (CTV) 1 received 45 GyRBE and CTV2 received 50.4 GyRBE following GTR or 54-55.8 GyRBE following biopsy or subtotal resection. Median follow-up was 3.7 years (range, 0.26-8.3); no patients were lost. The 4-year local control, disease-free survival, and overall survival rates were 96%, 86%, and 92%, respectively. Two patients experienced in-field recurrences. One patient experienced bilateral conductive hearing loss requiring aids, two patients developed intracranial vasculopathy, and 6 patients required hormone replacement therapy for neuroendocrine deficits. None developed a secondary malignancy. CONCLUSION Proton therapy is associated with a favorable therapeutic ratio in children with large Ewing tumors of the cranium and skull base. Despite its high conformality, we observed excellent local control and no marginal recurrences. Treatment dosimetry predicts limited long-term neurocognitive and neuroendocrine side effects.

Abstract
Radiation therapy (RT) can be lethal to a developing fetus; therefore, determining pregnancy status before RT is essential. We here sought to determine how many women treated with RT at our institution for over one year were at risk for pregnancy when starting RT. We retrospectively reviewed the medical records of all female patients 12–55 years old treated with radiation, i.e. 1 October 2012 to 31 September 2013. Patients were categorised as ‘at risk’ if they had a uterus and ‘no risk’ if they had a hysterectomy. Documented birth control, pregnancy test status, and timing of the pregnancy test in relation to the radiation start date were recorded. We included 131 female patients with a median age of 48 years (range 14–55 years). Breast cancer was the most prevalent disease site (18%) followed by head/neck and central nervous system (both 11%). Of the 131 patients, 35 were deemed ‘no risk’ and 95 (72%) were ‘at risk’. Pregnancy testing of the ‘at risk’ population was done in 47%, but only 17% of the pregnancy testing was performed accurately, which we defined as a test performed within 14 days before starting RT. Over one year, 66% (63/95) of ‘at risk’ women were not tested appropriately before starting RT. Most (66%) women of child-bearing age with an intact uterus receiving RT at our institution were not appropriately tested for pregnancy before the initiation of RT. These data laid the foundation for our formal pregnancy testing policies for women undergoing RT.
