Study Description

Brief Summary: A multi-centre, double-blind, randomized-controlled trial to study the efficacy and safety of gabapentin to reduce the need for strong opioid use in the treatment of radiation-induced pain in head and neck cancer (HNCA) patients undergoing a curative 7-week radio(chemo)therapy course with curative intent. The aim of this study is to establish if addition of gabapentin is more effective in reducing the need to start (or dosage-increase) a strong opioid for HNCA pain than a matching placebo additional to standard pain management (WHO-ladder step 2 and 3).

Detailed Description: Although pain is a major symptom in head and neck cancer (HNCA) patients, few studies focus on pain management in this population. Current optimal HNCA pain control usually requires the use of a strong opioid (WHO-ladder step 3), increasing the risk of opioid side effects and toxicities. Gabapentin, originally an anticonvulsant drug, has been effectively used off-label to treat multiple neuropathic pain syndromes such as cancer pain, and has been suggested to reduce the need for high doses of strong opioids in HNCA patients under radio(chemo)therapy. A multi-centre, phase III, double-blind, randomised-controlled trial will be set up randomising patients between the experimental group (E) receiving gabapentin, or the control group (C) receiving a matching placebo, both in addition to standard analgesic therapy (steps 2 and 3 on WHO-ladder). The investigators aim to establish if addition of gabapentin is more effective in reducing the need to start (or dosage-increase) a strong opioid for HNCA pain than a matching placebo additional to standard pain management (WHO-ladder step 2 and 3), in HNCA patients scheduled for a curative 7-week radio(chemo)therapy course.
