Background: The first line definitive treatment for early-stage indolent B-cell lymphoma is radiation therapy (RT). Due to the sensitivity of orbital structures to radiation, ultra-low-dose RT (4 Gy in 2 fractions, "boom-boom") has and been utilized as an attractive option for orbital lymphoma. In this retrospective study, we evaluated the outcome and toxicity of "boom-boom" RT for indolent orbital lymphoma with an emphasis on ophthalmologic toxicity.

Despite advances in molecular and genetic profiling studies identifying several predictive biomarkers, none has been translated into routine clinical use. Our aim was to investigate the prognostic significance of a panel of diverse cellular molecular markers of tumor formation and growth in an annotated glioblastoma tissue microarray (TMA).

Purpose: To describe outcomes of 6 patients treated with plaque radiotherapy for medulloepithelioma.
Design: Retrospective review.
Methods: Computerized medical records were reviewed for patients with cytopathologically confirmed medulloepithelioma and treated with plaque radiotherapy from January 1970 to December 2017.
Importance: Early detection of choroidal melanoma at a small tumor size is emphasized in the literature. However, there is little published information on the specific risks of plaque-irradiated small choroidal melanoma on visual acuity and metastasis.
Objective: To analyze outcomes of plaque radiotherapy for small choroidal melanoma 3 mm in thickness or less.
Purpose: This registry trial studied the long-term outcomes of women receiving accelerated partial breast irradiation (APBI) using strut-based applicators and reports on the local control, toxicity, and survival for the first 250 patients treated with this device.
Methods And Materials: Patients were treated using the strut-based brachytherapy device with conventional dose and fractionation of 34 Gy in 10 twice-daily fractions. Planning goals for the planning target volume were V > 90%, V < 50 cc, and V < 20 cc.
Objective: Few studies have evaluated re-irradiation of lung cancer recurrences with stereotactic body radiotherapy (SBRT). This study evaluates outcomes with SBRT re-irradiation for recurrent lung cancer.
Methods: Two hundred and seventy-eight patients treated with SBRT for lung cancer were retrospectively reviewed.
Importance: The treatment of juxtapapillary choroidal melanoma is challenging because of the proximity of the tumor to visually important structures.
Objective: To report the complications of treatment of juxtapapillary choroidal melanoma with plaque radiotherapy.
Design, Setting, And Participants: In this retrospective case series of patients from the Ocular Oncology Service, Wills Eye Hospital, 650 consecutive eyes with juxtapapillary choroidal melanoma (≤1 mm to optic disc) treated with plaque radiotherapy from October 1, 1974, through November 30, 2005, were studied.
Importance: Conjunctival squamous cell carcinoma (SCC) is surgically managed with wide surgical excisional biopsy, superficial keratectomy, and cryotherapy. In eyes with residual tumor showing scleral invasion or intraocular involvement, enucleation is advised.
Objective: To explore the role of plaque radiotherapy for residual invasive conjunctival SCC as an alternative to enucleation.
Purpose: To identify risk factors and outcome of scleral necrosis after plaque radiotherapy of uveal melanoma.
Design: Case-control study.
Participants: A total of 73 cases with scleral necrosis and 73 controls without necrosis after plaque radiotherapy.
Purpose: To evaluate the outcomes of iris melanoma managed with plaque radiotherapy on the basis of the initial presence or absence of glaucoma.
Design: Retrospective, comparative case series.
Participants: A total of 144 patients.

Purpose: To provide a retrospective analysis of the efficacy of hyperbaric oxygen therapy (HBOT) for treating hemorrhagic cystitis (HC) and proctitis secondary to pelvic- and prostate-only radiotherapy.
Methods And Materials: Nineteen patients were treated with HBOT for radiation-induced HC and proctitis. The median age at treatment was 66 years (range, 15-84 years).
Purpose: To evaluate plaque radiotherapy for management of residual or recurrent iris melanoma after surgical resection.
Design: Retrospective, nonrandomized interventional case series.
Participants: We included 32 patients with residual or recurrent iris melanoma after surgical resection.
Purpose: Because of the risk of skin toxicity with single dwell position, single-lumen brachytherapy devices are sometimes contraindicated for tumor cavities 5-7mm from the skin surface. We discuss the use of multicatheter device to treat patients with tumor bed-to-skin distances <7mm.
Methods And Materials: We treated 117 patients with accelerated partial-breast irradiation brachytherapy: 77 single-lumen and 40 multicatheter devices.
We compare long-term outcomes in patients with node negative early stage breast cancer treated with breast radiotherapy (RT) without the axillary RT field after sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND). We hypothesize that though tangential RT was delivered to the breast tissue, it at least partially sterilized occult axillary nodal metastases thus providing low nodal failure rates. Between 1995 and 2001, 265 patients with AJCC stages I-II breast cancer were treated with lumpectomy and either SLND (cohort SLND) or SLND and ALND (cohort ALND).

Design: Retrospective, comparative case series.
Participants: We included 650 consecutive eyes with juxtapapillary choroidal melanoma within 1 mm of the optic disc.
Objective: To evaluate tumor control with plaque radiotherapy for juxtapapillary choroidal melanoma that overhangs the optic disc.
Methods: Retrospective medical record review of 141 consecutive patients with data on complications of treatment, final visual acuity, visual loss, enucleation, tumor recurrence, metastasis, and death.
Results: The median patient age was 61 years.
Objective: To report results of plaque radiotherapy for choroidal melanoma that completely encircles the optic disc (circumpapillary melanoma).
Methods: Retrospective medical record review over a 31-year period of 37 consecutive patients. The main outcome measures were treatment complications, long-term visual acuity, enucleation, tumor recurrence, metastasis, and death.
Purpose: To assess tumor control and complications of iodine 125 (I125) plaque radiotherapy for retinoblastoma recurrence after chemoreduction (CRD).
Design: Interventional retrospective case series.
Participants: Children with retinoblastoma treated on the Oncology Service, Wills Eye Hospital, initially examined from July 1994 to April 2005.
The purpose of this study was to determine patterns of ipsilateral breast tumor recurrence (IBTR) and local-regional recurrence (LRR) after neoadjuvant chemotherapy and breast-conserving therapy (BCT). A total of 153 breast cancer patients were treated with neoadjuvant chemotherapy followed by conservative surgery and radiation therapy between 1980 and 2002. The clinical stage (American Joint Committee on Cancer [AJCC] 1997) at diagnosis was IIA in 22%, IIB in 28%, IIIA in 39%, and IIIB in 11%.

Methods: A custom-designed Iodine-125 plaque, designed to deliver a target dose of 50 Gray, was placed surgically in the region from which an orbital malignancy was partially resected. The mean dose to the target area was 50 Gray.
Purpose: Positive surgical margins adversely influence local tumor control in breast conservation therapy (BCT). However, reports have conflicted regarding whether an increased radiation dose can overcome this poor prognostic factor. In this study, we evaluated the influence of an increased radiation dose on tumor control in women with positive surgical margins undergoing BCT.
