Abstract
Opioids are widely administered to alleviate pain, including chronic pain in advanced cancer patients. Among opioids, morphine
is one of the most clinically effective drugs for the palliative management of severe pain. In the last few decades, there has been a
debate around the possible influence of opioids such as morphine on tumour growth and metastasis. Whilst several in vitro and
in vivo studies suggest the possible modulatory effects of morphine on tumour cells, little is known about the impact of this
analgesic drug on other mediators such as matrix metalloproteinases (MMPs) that play a key role in the control of cancer cell
invasion and metastasis. MMP-9 has been considered as one of the principal mediators in regulation of not only the initial steps of
cancer but during the invasion and spreading of cancer cells to distant organs. Herein, current studies regarding the direct and
indirect effects of morphine on regulation of MMP-9 production are discussed. In addition, drawing from previous in vivo and
in vitro studies on morphine action in regulating MMP-9 production, the potential roles of several underlying factors are
summarised, including nuclear factor kappa-B and intracellular molecules such as nitric oxide.
