The purpose of this study is to evaluate the effectiveness and tolerability of Once-Daily OROS ("Osmotic Release Oral System" \[a controlled release oral medication delivery system in the form of a tablet\]) hydromorphone for cancer pain treatment in Korean cancer patients.
This is a prospective (expected to happen), open-label (type of clinical study in which both the researchers and participants know which treatment is being administered), multicenter (conducted at multiple centers), single-arm (only one group), study to evaluate the effectiveness and tolerability (capable to tolerate) of Once-Daily OROS hydromorphone for cancer pain treatment. This is a 14-week study consisting of 2-week efficacy evaluation period (1st evaluation on Day 1 and 2nd evaluation on Days 15±2) and a 12-week extension phase. 99 patients will receive Once-Daily OROS hydromorphone for 2 weeks .After 2 weeks, if a patient has continuous cancer pain and the investigator deems it necessary to administer the same medicine as the study medication then the patient may participate voluntarily in the 12 weeks extension phase. At the extension phase, other continuous-type strong opioid analgesics (painkiller) may be administered at the same time for the adjustment of cancer pain based on the discretion of the investigator.

Type= exact number, unit= mg, number= 4, form= tablet, route= oral, administered from 1st evaluation day (Day 1) to 2nd evaluation day (Day 15±2). Dosage adjustment: If NRS (Numeric Rating Scale) =4 or more then dose can be increased by 4mg until the average pain intensity for the past 24 hours is adjusted to lower than NRS 3. For the treatment of breakthrough pain, if necessary the one-time administration dose of quick-effect OROS Hydromorphone shall be 2mg up to the daily dosage of the study medicine, 12mg.

Number of patients with 50% or more average Pain Intensity Difference (PID) from 1st evaluation day (Day 1) to the 2nd evaluation day (Days 15±2)
Average pain intensity is calculated (on 1st and 2nd evaluation days) for the past 24 hours of the patient using the NRS (Numeric Rating Scale) (0 = No pain, 10 = Unimaginably acute pain). PID (pain intensity difference) %= \[NRS (1st evaluation day) - NRS (2nd evaluation day)\]/ NRS (1st evaluation day).
Time frame: up to 17 days
Korean Brief Pain Inventory (K-BPI) scores
A survey (questionnaire) to measures the pain intensity, the effect of pain on the performance of everyday life, effect of medicines for pain treatment and degree of pain reduction.
Time frame: up to 17 days
European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) scores
Quality of life measurement survey with 30 questions that ask about the health status of cancer patients.
Time frame: up to 17 days
Patient's Global Assessment (PGA) scores
Patient checks any of the 5 stages: 1 = Not effective, 2 = Normal, 3 = Effective, 4 = Very Effective, 5 = Excellently effective based on how effective the study medication is in their treatment of pain after the last evaluation.
Time frame: up to 17 days
Investigator's Global Assessment scores
Study investigator checks any of the 5 stages: 1 = Not effective, 2 = Normal, 3 = Effective, 4 = Very Effective, 5 = Excellently effective based on how effective the study medication is in their treatment of pain after the last evaluation.
Time frame: up to 17 days
