Low-Dose Radiotherapy

Low-dose radiotherapy for primary cutaneous anaplastic large-cell lymphoma while on low-dose methotrexate.

Primary cutaneous anaplastic large-cell lymphoma (pcALCL) is part of a spectrum of CD30+ primary cutaneous lymphoproliferative disorders (pcLPDs) that also includes lymphomatoid papulosis (LyP). Localized radiotherapy at doses of 34 to 44 Gy is first-line treatment of pcALCL, but the use of low-dose radiotherapy for pcALCL has not been reported. We present the case of a patient with a history o...

Surgical Excision Followed by Low Dose Rate Radiotherapy in the Management of Resistant Keloids

BACKGROUND Depending on the cause, 40-90% of every deep dermis insult ends up in scar formation. Several modalities have been suggested as a treatment but a high rate of recurrence is reported in most of those interventions. High dose radiotherapy has been shown to be effective in reducing the recurrence rate. This study tried to determine the effectiveness of low dose rate radiotherapy follow...

Use of Pulsed Low–Dose Rate Radiotherapy in Refractory Malignancies12

BACKGROUND Most tumor cell lines exhibited low-dose hyperradiosensitivity (LDHRS) to radiation doses lower than 0.3 Gy. Pulsed low-dose rate radiotherapy (PLDR) took advantage of LDHRS and maximized the tumor control process. In this study, we retrospectively analyzed patients receiving PLDR for refractory malignancies. PATIENTS AND METHODS In total, 22 patients were included in our study: 9 ...

Salvage low-dose-rate 125I partial prostate brachytherapy after dose-escalated external beam radiotherapy

PURPOSE To report outcomes on 5 patients treated with salvage partial low-dose-rate (LDR) 125-iodine ((125)I) permanent prostate seed brachytherapy (BT) for biopsy-proven locally persistent prostate cancer, following failure of dose-escalated external beam radiotherapy (EBRT). MATERIAL AND METHODS A retrospective review of the Fox Chase Cancer Center prostate cancer database identified five p...
