The most appropriate dose fractionation for whole-breast irradiation (WBI) remains uncertain.To assess acute and 6-month toxic effects quality of life (QOL) with conventionally fractionated WBI (CF-WBI) vs hypofractionated (HF-WBI).Unblinded randomized trial CF-WBI (n = 149; 50.00 Gy/25 fractions + boost [10.00-14.00 Gy/5-7 fractions]) HF-WBI 138; 42.56 Gy/16 [10.00-12.50 Gy/4-5 following breast-conserving surgery administered in community-based academic cancer centers to 287 women 40 years...

Although surgery is considered standard therapy for unicentric Castleman disease, favorable responses to radiotherapy also have been documented. The authors undertook this study analyze the clinical factors, treatment approaches, and outcomes of patients with or multicentric report disease treated radiotherapy.The reviewed medical records 22 who had received a histologic diagnosis at University Texas M. D. Anderson Cancer Center between 1988 1999. One patient concurrent histopathologic...

[(18)F]Fluorodeoxyglucose positron emission tomography (FDG-PET)/computed (CT) imaging may improve assessment of radiation response in patients with head and neck cancer, but it is not yet known for which this most useful. We conducted a prospective trial to identify patient populations likely benefit from the addition functional radiotherapy response.

The adoption of hypofractionated whole-breast irradiation (HF-WBI) remains low, in part because concerns regarding its safety when used with a tumor bed boost or patients who have received chemotherapy large breast size. To address this, we conducted randomized, multicenter trial to compare conventionally fractionated (CF-WBI; 50 Gy/25 fx + 10 14 Gy/5 7 fx) HF-WBI (42.56 Gy/16 12.5 Gy/4 5 fx).

Abstract Background Pathologic extranodal extension (pENE) is a crucial prognostic factor in oropharyngeal cancer (OPC), but determining pENE from imaging has high inter‐observer variability. The role of clinician specialty the accuracy imaging‐detected (iENE) remains unclear. purpose this study to assess influence on preoperative iENE detection human papillomavirus (HPV)‐positive OPC using computed tomography (CT) imaging. Methods This prospective observational evaluated pretherapy CT...

Abstract BACKGROUND Lymphocyte‐predominant Hodgkin disease (LPHD) is rare and has a natural history different from that of classic disease. There little information in the literature regarding role chemotherapy patients with early‐stage LPHD. The objective this study was to examine recurrence free survival (RFS), overall (OS), patterns first LPHD who were treated radiotherapy alone or followed by radiotherapy. METHODS From 1963 1996, 48 consecutive ages 16–49 years (median, 28 years) Ann...

PURPOSE Clinical efficiency is a key component of value-based health care. Our objective here was to identify workflow inefficiencies by using time-driven activity-based costing (TDABC) and evaluate the implementation new clinical in high-volume outpatient radiation oncology clinics. METHODS quality improvement study conducted with Departments GI, Genitourinary (GU), Thoracic Radiation Oncology at large academic cancer center four community network sites. TDABC used create process maps...

We describe the development of 3D-printed stents using our digital workflow and their effects on patients enrolled in lead-in phase a multi-center, randomized Phase-II trial. Digital dental models were created for intraoral scanning. processes implemented to develop mouth-opening, tongue-depressing, tongue-lateralizing stereolithography. Time spent material 3D-printing costs measured. Physicians assessed mucositis Oral Mucositis Assessment Scale (OMAS) collected MD Anderson Symptom Inventory...

Abstract BACKGROUND The relative importance of prognostic factors in patients with early‐stage Hodgkin disease remains controversial. purpose this study was to evaluate among who received chemotherapy before radiotherapy. METHODS From 1987 1995, 217 consecutive ranging age from 16 88 years (median, 28 years) Ann Arbor Stage I ( n = 55) or II 162) underwent radiotherapy at a single center. Most were treated on prospective studies. Patients median three cycles induction chemotherapy....
