Is There an Opportunity to De-Escalate Treatments in Selected Patients with Metastatic Hormone-Sensitive Prostate Cancer?

The treatment landscape for metastatic hormone-sensitive prostate cancer continues to evolve, with systemic treatment being the mainstay of current treatment. Prognostic and predictive factors such as tumour volume and disease presentation have been studied to assess responses to different treatments. Intensification and de-escalation strategies arouse great interest, so several trials are being developed to further personalize the therapy in these populations. Is there an optimal sequence and a possible option to de-intensify treatment in selected patients with a favourable profile? This and other goals will be the subject of this review

Quality of life improvement in patients with bone metastases undergoing palliative radiotherapy.

The aim of the study was to analyze the impact of palliative radiotherapy on quality of life (QoL) in patients with symptomatic bone metastases. We present the results from a prospective multicentric study including 128 patients who provided pre- and post-radiotherapy (one month after treatment) brief pain inventory (BPI) assessments. Worst pain was recorded using the BPI (range: 0-10). Pain response was described according to the International Bone Metastases Consensus on palliative radiation. Regarding QoL, for each pre- and post-radiation BPI-questionnaire, scores from the interference domains were summed and averaged to obtain an overall interference score. There was a significant correlation between radiation treatment response and improvement in all functional interference domains except sleeping. Patients > 75 years old presented a significantly higher improvement in general activity, mood and relationships with others compared to patients ≤ 75 years old. Patients presenting a baseline pain score ≥ 8 showed a higher improvement in the general activity item (p = 0.049). There was no statistically significant association between pretreatment ECOG, chemotherapy, primary tumor location and radiation schedule with any of the functional interference items. Patients who report pain relief after palliative radiotherapy also present a better quality of life including physical and psychosocial aspects

Journal Article; Research Support, Non-U.S. Gov't;BACKGROUND Palliative radiotherapy (RT) is an effective treatment for symptomatic bone metastases. Pain flare, a transient worsening of the bone pain after RT, has been described in previous reports with different incidence rates. The aim of the study was to prospectively evaluate the incidence of pain flare following RT for painful bone metastases and evaluate its effects on pain control and functionality of the patients. METHODS Between June 2010 and June 2014, 204 patients were enrolled in this study and 135 patients with complete data were evaluable. Pain flare was defined as a 2- point increase in worst pain score as compared with baseline with no decrease in analgesic intake or a 25% increase in analgesic intake as compared with baseline with no decrease in worst pain score. All pain medications and worst pain scores were collected before, daily during, and for 10 days after RT. The Brief Pain Inventory (BPI) was filled out on the pretreatment and at the 4 weeks follow-up visit. RESULTS There were 90 men (66.7%) and 45 women (33.3%). Mean age was 66 years (SD 9.8). The most common primary cancer site was lung in 42 patients (31.1%), followed by prostate in 27 patients (20.0%). Forty-two patients (31.1%) patients received a single fraction of 8 Gy and 83 (61.5%) received 20 Gy in five fractions. The overall pain flare incidence across all centers was 51/135 (37.7%). The majority of pain flares occurred on days 1-5 (88.2%). The mean duration of the pain flare was 3 days (SD: 3). There were no significant relationships between the occurrence of pain flare and collected variables. All BPI items measured four weeks after end of RT showed significant improvement as compared with pretreatment scores (p < 0.001). No significant differences in BPI time trends were found between patients with and without flare pain. CONCLUSION Pain flare is a common event, occurring in nearly 40% of the patients that receive palliative RT for symptomatic bone metastases. This phenomenon is not a predictor for pain response.This study was supported by the Health Department of Basque Government Research Grant (RECORD NUMBER: 2010111072) and a FIS Carlos III Health Institute Grant (RECORD NUMBER: PI11/01930).Ye
