23 Primary Outcome

Primary Parameters:
The primary parameters are:
The dose of TTS-fentanyl:
The investigator will record the dose of TTS-fentanyl used by the patient and the date of change.

Pain Score Assessment:
The severity of pain will be evaluated by average pain score in 24 hours using Numerical Rating Scale (NRS). The patient will complete his/her diary daily.

Overall Satisfaction in Pain Control:
The patient will make a global assessment of his/her pain treatment using a 4-point scale (excellent, good, fair, poor) at the start of the study (visit 2), visit 3 and at the end of the study (day 28, visit 4) with investigator.

24 Secondary Outcome

Secondary Parameters:
Nausea, Vomiting and Sedation:
The severity will be evaluated using a 4-point scale: absent, mild, moderate, severe and recorded in the patient’s diary. The frequency of vomiting and his concomitant medication will be recorded on the diary. It will also be evaluated by investigator at each study visits.

Gastrointestinal disturbances
The investigator will assess the effects on the gastrointestinal track by evaluating the number, the consistency and the passage of stools, the presence of abdominal pain and bloating and the use of laxatives at each visit.

Evaluation of the use of the patches.
The patient will be asked to rate the convenience of the patches on a 4-point scale (excellent, good, fair, poor) at visit 3 and 4. The patient must be instructed to report any early removal of patch (<3days) immediately to the investigator. An overall evaluation on patient’s preference will also be made at visit 4 or end of the trial.

General condition.
The investigator will record the patients’ general condition using the Palliative Performance Scale at the start of the study (visit 2) and further at all study visits.
