For relief from cancer pain, we developed critical pathway (CP) as an effective strategy for the medical staff treating cancer patients. This CP was made out of Microsoft Excel, and was used on personal computers. "Good sleeping" was set as the first goal and the second was "No pain in rest position." To achieve this, physicians and nurses evaluate medical efficacy and complications including nausea/vomiting, constipation, somnolence and hallucination everyday using controlled release oxycodone in addition to NSAIDs and prochlorperazine, stool softener and peristaltic stimulant for adverse effects. These outcomes lead to the medication change the next day by calculation using visual basic function due to opioid titration theory. In twelve patients this CP was acceptable, and all of them achieved the second goal within a week without severe adverse effects except constipation.

The physiochemical characteristics of the potent synthetic opioid agonist fentanyl make it ideal for noninvasive transmucosal delivery. Studies of oral transmucosal fentanyl citrate (OTFC), a candied matrix formulation administered orally as a palatable lozenge on a stick, have investigated and determined this analgesic's pharmacokinetics and pharmacodynamics in a number of clinical settings, including premedication before surgery, acute analgesia for painful medical procedures, and, most recently, for the control of breakthrough cancer pain. The onset to meaningful pain relief in patients with acute pain from surgery or breakthrough pain from cancer is between 5 and 10 minutes after initiating OTFC use, equivalent to intravenous morphine. Analgesic dose equivalency studies suggest that OTFC is, on average, about 10 times more potent than morphine, although, in randomized, controlled, and blinded studies, many patients who were using relatively high doses of opioid anlagesics on an around the- clock schedule for control of cancer pain reported that even a low dose of OTFC (i.e., 200 microg) provided adequate relief from breakthrough pain. Side effects from OTFC are similar in character and frequency to other opioids, including sedation, nausea, and pruritus. These effects appear to wane rapidly with repeated use of this medication. To date there have been no reported serious adverse events in any of the population groups studied or treated with OTFC.

The transdermal matrix patch formulation of buprenorphine has been shown to be effective in managing moderate-to-severe cancer pain and severe pain unresponsive to nonopioid analgesics. Clinical trials have revealed that it is possible to switch from weak opioids or low doses of step III opioids to transdermal buprenorphine without any problems. With buprenorphine patches, the sublingual buprenorphine intake was dose-dependently reduced and was superior to placebo in this respect. The proportion of responders increased with the buprenorphine dose, and a higher proportion of patients receiving buprenorphine patches reported uninterrupted sleep for longer than 6 h compared with those receiving placebo. In a long-term, open, follow-up study in which the mean duration of treatment was 7.5 months, analgesia was rated as at least satisfactory by 90% of patients. Almost 60% of patients could manage their pain with one patch alone or with one additional sublingual tablet a day during the whole period of treatment, indicating a low incidence of tolerance development. The buprenorphine transdermal patch was assessed as user friendly by 94.6% of patients. In a postmarketing surveillance study, pain relief with transdermal buprenorphine was rated as good or very good by 70% of the responders. Postmarketing surveillance studies have shown that transdermal buprenorphine is also effective in the management of nociceptive and neuropathic pain, which some studies have shown to be relatively insensitive to mu-opioid analgesics, such as morphine. Transdermal buprenorphine was well tolerated. Most adverse events were either local reactions to the patch that generally subsided within 24 h or systemic events typical of treatment with opioid analgesics, such as nausea, vomiting and constipation.

The synthetic opioid methadone has generated much interest in recent years among clinicians involved in the management of intractable chronic cancer pain. Its use as an analgesic is starting to extend to the treatment of noncancer pain, particularly neuropathic pain. Unfortunately, the evidence for its use in the management of neuropathic pain is limited to a few case studies. We examined retrospectively during a 12-month study period the clinical response of all 13 patients at our pain clinic who were prescribed methadone in an attempt to control neuropathic pain resistant to conventional analgesics. A questionnaire was also administered to the 9 patients who continued to take methadone at 12 months posttreatment. A total of 4 patients (31%) discontinued it by the end of the 12-month study period. Patients discontinued methadone due to the absence of pain relief and due to various intractable, undesirable side effects. Somnolence was the most common adverse effect reported, followed by nausea, constipation, and vomiting. All patients took coanalgesics (eg, amitriptyline, gabapentin) or other analgesics (eg, morphine, nonsteroidal anti-inflammatory drugs) during methadone treatment to control pain. The 9 patients who continued to take methadone at 12 months reported experiencing on average 43% pain relief (range 0-80%), 47% improvement in quality of life (range 0-100%), and 30% improvement in quality of sleep (range 0-60%). Methadone was effective at relieving pain and ameliorating quality of life and sleep in 62% of patients. These findings suggest that methadone can offer an acceptable success rate for the treatment of neuropathic pain. Prospective randomized, placebo-controlled studies are now needed to examine more rigorously the benefits of methadone for this type of pain.

Cancer pain treatment should follow the recommendations of the World Health Organisation. Treatment should be with oral application, regular application times and following the analgesic step-ladder. Non-opioids such as dipyrone or non-steroids are used for slight to moderate pain, step-2 opioids such as tramadol or tilidine/naloxone for moderate pain and step-3 opioids such as morphine, oxycodone or hydromorphone for severe pain. Transdermal application of fentanyl or buprenorphine offer a non-invasive parenteral alternative for patients with stable pain syndromes. Cannabinoids such as tetrahydrocannabinol offer a valuable add-on option for cancer patients with refractory pain, spasticity, nausea or appetite loss.

The majority of patients with advanced cancer experience weight loss, reduced appetite, fatigue, and weakness. Chronic nausea and early satiety may also occur. This constellation of symptoms is known as the cancer anorexia-cachexia syndrome. Together with cancer pain, cancer anorexia-cachexia syndrome has been identified as 1 of the 2 most frequent and devastating problems affecting individuals with advanced malignancies. Research examining the issue of cancer anorexia-cachexia syndrome has been conducted; however, such work is largely biomedical in orientation. In contrast, the psychologic dimensions of the cancer anorexia-cachexia syndrome experience from the perspective of terminally ill patients and their family members is less well explored or described. The ability to provide psychosocial support to patients and families requires that caregivers appreciate the psychologic effect of cancer anorexia and cachexia on these individuals. This article examines that effect in light of existing knowledge and discusses the clinical implications arising from this work.

Adverse events of opioids may restrict their use in non-cancer pain. Analysis of the incidence of common adverse events in trials conducted in non-cancer pain has usually been limited to opioids used to treat severe pain according to the WHO three-step ladder. To examine the incidence of common adverse events of opioids in non-cancer pain, a systematic review and meta-analysis of information from randomised trials of all opioids in non-cancer pain was undertaken. Studies used were published randomised trials of oral opioid in non-cancer pain, with placebo or active comparator. Thirty-four trials with 5,546 patients were included with 4,212 patients contributing some information on opioid adverse events. Most opioids used (accounting for 90% of patients) were for treating moderate rather than severe pain. Including trials without a placebo increased the amount of information available by 1.4 times. Because of clinical heterogeneity in condition, opioid, opioid dose, duration, and use of titration, only broad results could be calculated. Use of any oral opioid produced higher rates of adverse events than did placebo. Dry mouth (affecting 25% of patients), nausea (21%), and constipation (15%) were the most common adverse events. A substantial proportion of patients on opioids (22%) withdrew because of adverse events. Because most trials were short, less than four weeks, and because few titrated the dose, these results have limited applicability to longer-term use of opioids in clinical practice. Suggestions for improved studies are made.

Therapeutic massage as a cancer pain intervention appears to be safe and effective. Patients who receive massage have less procedural pain, nausea, and anxiety and report improved quality of life. The use of massage in cancer care centers and hospitals is on the rise. Massage has a positive effect on biochemistry, increasing levels of dopamine, lymphocytes, and natural killer cells. Specialized training of massage therapists in caring for people with cancer is recommended. Most studies to date are small but promising. Exact methodology and best practices warrant further investigation by the industry. More randomized clinical trials and case studies must be conducted.

Complementary and alternative medicine (CAM) use among cancer patients varies according to geographical area, gender, and disease diagnosis. The prevalence of CAM use among cancer patients in the United States has been estimated to be between 7% and 54%. Most cancer patients use CAM with the hope of boosting the immune system, relieving pain, and controlling side effects related to disease or treatment. Only a minority of patients include CAM in the treatment plan with curative intent. This review article focuses on practices belonging to the CAM domains of mind-body medicine, CAM botanicals, manipulative practices, and energy medicine, because they are widely used as complementary approaches to palliative cancer care and cancer symptom management. In the area of cancer symptom management, auricular acupuncture, therapeutic touch, and hypnosis may help to manage cancer pain. Music therapy, massage, and hypnosis may have an effect on anxiety, and both acupuncture and massage may have a therapeutic role in cancer fatigue. Acupuncture and selected botanicals may reduce chemotherapy-induced nausea and emesis, and hypnosis and guided imagery may be beneficial in anticipatory nausea and vomiting. Transcendental meditation and the mindfulness-based stress reduction can play a role in the management of depressed mood and anxiety. Black cohosh and phytoestrogen-rich foods may reduce vasomotor symptoms in postmenopausal women. Most CAM approaches to the treatment of cancer are safe when used by a CAM practitioner experienced in the treatment of cancer patients. The potential for many commonly used botanical to interact with prescription drugs continues to be a concern. Botanicals should be used with caution by cancer patients and only under the guidance of an oncologist knowledgeable in their use.

Little information is available about the incidence, prevalence, or severity of morphine side effects during repeated individualized dosing for chronic cancer pain, although it has been widely used in this way for more than 30 years. The authors' aim was to describe the prevalence of symptoms possibly attributable to morphine side effects in a convenience sample of patients with pain due to advanced cancer. They used a prospective survey of inpatients and outpatients on regularly dosed morphine, with a questionnaire administered weekly for 4 weeks. Forty-two of 56 eligible patients completed at least the first questionnaire, with 30 completing all 4. Dry mouth was the most common symptom reported (point prevalence, 95%); this was often moderate to severe in intensity (57%) and was the most persistent symptom (period prevalence, 20%). Sedation and constipation were frequent (point prevalence, 88%) and was often moderate or severe at some point (55% and 62%, respectively) but had low period prevalence. Nausea was reported by less than half the patients. Myoclonus was common (point prevalence, 83%) but was usually mild and not persistent. Total daily morphine dose had little impact on side-effect patterns. Constipation, dysphoria, myoclonus, nausea, and sedation were more likely to be severe following dose increases. In conclusion, although constipation, nausea, and sedation are well described as side effects of morphine administration, others such as dry mouth and myoclonus appear to be underestimated. Validated patient-based measures of opioid side effects are needed.
