Trial Outcomes & Findings for Morphine After Radiofrequency Ablation of Painful Bone Metastases in Patients With Cancer (NCT NCT00712712)

NCT ID: NCT00712712

Last Updated: 2025-08-29

Results Overview

Difference in maximum pain scores between inclusion and 2 months after radiofrequency ablation (RFA) according to an 11-point numerical scale Rate of patients with a decrease of two or more points in their most intense pain, 2 months after the radiofrequency ablation. This rate is calculated for the evaluable population for the principal outcome measure. This rate is equal to the ratio of the number of patients with a decrease of two or more points in their maximum pain divided by the size of the evaluable population. The response rate considered acceptable is 50%, above this threshold the treatment will be considered potentially effective and may be proposed in phase III.

PRIMARY outcome

Timeframe: 2 months after radiofrequency ablation (RFA)

Population: Pre-selected patients meeting the inclusion and exclusion criteria. Excluded patients who died, were lost to follow-up, or dropped out of the study within eight weeks after radiofrequency. If 25 patients or more are observed with pain reduction of 2 or more points, then the treatment will be considered potentially effective.

SECONDARY outcome

Timeframe: Inclusion and 2 months after radiofrequency ablation (RFA)

Population: Pre-selected patients meeting the inclusion and exclusion criteria. Excluded patients who died, were lost to follow-up, or dropped out of the study within eight weeks after radiofrequency.

Difference in maximum pain scores between inclusion and 2 months after radiofrequency ablation (RFA) according to a discrete 11-points numerical scale. Increased/decreased pain is considered as a variation of at least one point on the numerical scale. If 25 patients or more are observed with pain reduction of 2 or more points, then the treatment will be considered potentially effective.

SECONDARY outcome

Timeframe: First algology assessment at pre-selection visit

Population: Pre-selected patients meeting the inclusion and exclusion criteria. Excluded patients who died, were lost to follow-up, or dropped out of the study within eight weeks after radiofrequency.

According to a discrete 11-points numerical scale which ranges from 0 (low pain) to 11 (intense pain), intensity of pain (Minimum, Average, Maximum) has been evaluated at different time point between pre-selection and up to 3 months after radiofrequency. Assessment of intensity of pain has been done in this order at: * Pre-selection visit: First algology assessment within a week (± 3 days) after the radiology consultation, * Inclusion visit: Second algology assessment (One week after the first algology assessment) * J-1: one day before radiofrequency * J+1: One day after radiofrequency * Discharge from hospital * 7 days after discharge from hospital * 1 month after radiofrequency * 2 months after radiofrequency * 3 months after radiofrequency Here, are presented only data collected at the pre-selection visit.

Quality of life Questionnaire -Core 30 (QLQ-C30) developed in 1986 by the European Organization for Research and Treatment of Cancer (EORTC) assesses quality of life across 15 dimensions : 5 functional dimensions : Physical functioning, Role functioning, Emotional, Cognitive functioning, Social functioning; 9 symptomatic dimensions: Fatigue, Nausea and vomiting, Pain, Dyspnea, Insomnia, Appetite loss, Diarrhoea, Financial difficulties; 1 global health dimension: Global health status/QoL Each dimension is a standardised score ranges from 0 to 100. A low score corresponds to a low functional level, an absence of symptoms or a low level of QoL/ overall health and, conversely, so that a high score corresponds to a high functional level, a high presence of symptoms or a high level of QoL/overall health.

SECONDARY outcome

Timeframe: 2 months after radiofrequency

Population: Pre-selected patients meeting the inclusion and exclusion criteria. Excluded patients who died, were lost to follow-up, or dropped out of the study within eight weeks after radiofrequency.

Quality of life Questionnaire -Core 30 (QLQ-C30) developed in 1986 by the European Organization for Research and Treatment of Cancer (EORTC) assesses quality of life across 15 dimensions : 5 functional dimensions : Physical functioning, Role functioning, Emotional, Cognitive functioning, Social functioning; 9 symptomatic dimensions: Fatigue, Nausea and vomiting, Pain, Dyspnea, Insomnia, Appetite loss, Diarrhoea, Financial difficulties; 1 global health dimension: Global health status/QoL Each dimension is a standardised score ranges from 0 to 100. A low score corresponds to a low functional level, an absence of symptoms or a low level of QoL/ overall health and, conversely, so that a high score corresponds to a high functional level, a high presence of symptoms or a high level of QoL/overall health.
