In pre-terminal and terminal gynaecological patients with persistent cancer pain, now it is possible to carry out some anthalgic methods associated or not to parenteral administration of non-narcotic or narcotic analgesic, i.e. intrathecal neurolytic injections and epidural narcotic administration. Many favourable results have been obtained by means of single or repeated 7% phenol in glycerine injections to patients with advanced but not terminal cancer affected by somatic and segmental pain or by perineal pain. In order to control more extensive pains, epidural injections of morphine in saline have been employed in preterminal patients. This method appears to be the best answer to many problems complained by the patients: pain, depression, malaise. As a matter of fact, low doses of epidural morphine induce both complete pain relief and sedation or slight drowsiness.

Most pre-clinical analgesic efficacy assays still involve nociceptive testing in rodents. This is despite concerns as to the relevance of these tests for evaluating the pain-preventative properties of drugs. More appropriate methods would target pain rather than nociception, but these are currently not available, so it remains unknown whether animal pain equates to the negatively affective and subjective/emotional state it causes in humans. Mouse cancer models are common despite the likelihood of substantial pain. We used Conditioned Place Preference (CPP) testing, assessments of thermal hyperalgesia and behaviour to determine the likelihood that MBT-2 bladder cancer impacts negatively on mouse welfare, such as by causing pain. There was no CPP to saline, but morphine preference in tumour bearing mice exceeded that seen in tumour-free controls. This occurred up to 10 days before the study end-point alongside reduced body weight, development of hyperalgesia and behaviour changes. These effects indicated mice experienced a negative welfare state caused by malaise (if not pain) before euthanasia. Due to the complexity of the assessments needed to demonstrate this, it is unlikely that this approach could be used for routine welfare assessment on a study-by-study basis. However, our results show mice in sufficiently similar studies are likely to benefit from more intensive severity assessment and re-evaluation of end-points with a view to implementing appropriate refinements. In this particular case, a refinement would have been to have euthanased mice at least 7 days earlier or possibly by provision of end-stage pain relief. CPP testing was found to be a helpful method to investigate the responses of mice to analgesics, possibly on a subjective level. These findings and those of other recent studies show it could be a valuable method of screening candidate analgesics for efficacy against cancer pain and possibly other pain or disease models.

A 61-year-old woman was introduced for consultation with a chief complaint of frequent vomiting. CT revealed a pancreatic body cancer approximately 40mm in size; an invading stenosis from the horizontal part of the duodenum to the jejunum, superior mesenteric artery, and portal vein, splenic vein obstruction, lymphadenopathy, and some ascitic fluid. We diagnosed a passage disorder due to the invasive stenosis from the horizontal part of the duodenum of the pancreatic body cancer to the jejunum, and subsequently performed a duodenum and jejunum bypass operation. We controlled cancer pain with opioid analgesia, and S-1 monotherapy was chosen as the primary chemotherapy. A tendency to increase and the cancer pain of the tumor was aggravated when 5 courses took effect, so gemcitabine plus nab-paclitaxel(GEM plus nab-PTX)therapy was chosen as the second-line chemotherapy because of adverse Grade 3 events due to difficulties with S-1 internal use. We tapered off the opioid analgesia dosage because the cancer pain was relieved after 1 course. The imaging top indicated stable disease at the end of 5 courses, but the pain was relieved so opioid pain killers were unnecessary. Foreign continuation is under treatment with 10-course GEM plus nab-PTX therapy after initial diagnosis. Currently, the patient has undergone 5 courses of S-1 for approximately 18 months, and has achieved stable disease. The only adverse events were nausea, fatigue, Grade 1 malaise, and Grade 2 alopecia, as detected with imaging.
