Shorter, Intensive Radiation Can Be Recommended in Early Prostate Cancer

This study has implications for public policy,” said the study’s principal investigator, W. Robert Lee, M.D., a professor in the Department of Radiation Oncology at Duke. “Because the shorter regimen has advantages such as greater patient convenience and lower costs, it’s important to establishing whether we can cure as many patients with the shorter regimen. Our study provides that information for the first time.” Lee and colleagues, working as part of NRG Oncology, a non-profit cancer research organization, enrolled about 1,100 men whose prostate cancer was diagnosed early, before it had spread. Roughly half the patients were randomly assigned to receive the typical regimen of 41 treatments; the other half received the higher dose over just 28 treatments. At five years, disease-free survival was no different between the two groups, with 85.3 percent of men in the traditional group being cancer-free, compared to 86.3 percent of men in the shorter regimen group. Overall survival at five years was also no different, at 93.2 percent and 92.5 percent respectively. Mild gastrointestinal and genitourinary toxicity as reported by doctors was observed more frequently in patients getting the higher daily dose, shorter frequency radiation, but no differences were observed in more severe side effects, which were rare (less than 5 percent) with either regimen. The researchers also asked patients to describe their own experiences of side-effects, but these d...

ConclusionsMaxillofacial manifestation of bone metastasis is common but is often overlooked. Therefore, it should be considered in the differential diagnosis when a patient with a history of antiresorptive medications presents with a gingival mass and/or exophytic bone. Good clinical judgment and well-timed bone biopsy and diagnostic imaging can lead to the correct diagnosis and optimal treatment.

Conclusions: Hypofractionated radiotherapy appears to be equally tolerated compared to conventional fractionation in the early setting. Longer follow up is needed to assess the late toxicity profile of the patients and any potential differences between the control and experimental arm.

For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late toxicities to nearby genitourinary and gastrointestinal organs at risk. Brachytherapy is a method to deliver dose escalation in conjunction with EBRT with a potentially improved late toxicity profile and improved prostate cancer related outcomes. At least three randomized controlled trials have demonstrated improved biochemical control with the addition of either low-dose rate (LD...

Abstract PURPOSE: Knowledge-based planning (KBP) techniques have been reported to improve plan quality, efficiency, and consistency in radiation therapy. However, plan complexity and deliverability have not been addressed previously for treatment plans guided by an established in-house KBP system. The purpose of this work was to assess dosimetric, mechanical, and delivery properties of plans designed with a common KBP method for prostate cases treated via volumetric modulated arc therapy (VMAT). METHODS: Thirty-one prostate patients previously treated with VMAT were replanned with an in-house KBP method based...

ConclusionIMRT at a dose up to 78  Gy combined with short-term neoadjuvant ADT resulted in excellent long-term disease-free outcomes with acceptable morbidities among patients with IR PCa. In addition, the incidence of late recurrence was very low. Further investigation is warranted to confirm our findings.

We present 3 cases with false-negatives for local (recurrent) prostate cancer on 68Ga-PSMA PET/CT, using multiparametric MRI and histopathology as reference standard. Metal artifact of prostate gold markers placed for external beam radiation therapy, low level of PSMA uptake, and bladder spillover are potential causes of misinterpretation. Awareness of these diagnostic pitfalls may improve 68Ga-PSMA PET/CT interpretation.
