This study compared the efficacy and the adverse effects of controlled-release morphine (CRM) suspension (SAR 213) and CRM tablets (Moscontin) in the treatment of cancer pain. This multicenter, randomized, double-blind, double-dummy, crossover study was carried out on 52 patients. Each patient received both study treatments given at an equivalent dosage of morphine during each of two 7-day periods. The primary outcome variable was the severity of pain assessed three times daily by means of a visual analogue scale. Secondary criteria of efficacy were the severity of pain assessed by verbal rating scale, the need for "rescue" doses of immediate-release morphine, treatment preference, and indices of quality of life (activity, mood, sleep). There were no statistically significant differences in the parameters assessed when comparing the two groups. This study shows that, when prescribed at the same doses, CRM suspension and CRM tablets have similar efficacy and adverse effects, as well as the same duration of action. The results of this first clinical study carried out on CRM suspension are especially relevant for patients with cancer pain who have difficulty swallowing.

In a prospective study, the prevalence of 15 physical symptoms and symptom groups was evaluated in 1635 cancer patients referred to a pain clinic. In addition to pain, patients suffered an average of 3.3 symptoms: insomnia (59%), anorexia (48%), constipation (33%), sweating (28%), nausea (27%), dyspnea (24%), dysphagia (20%), neuropsychiatric symptoms (20%), vomiting (20%), urinary symptoms (14%), dyspepsia (11%), paresis (10%), diarrhea (6%), pruritus (6%), and dermatological symptoms (3%). While symptom prevalence was influenced by tumor site, pain intensity, and opioid treatment, only a minor relationship was seen between symptoms and gender, age, or tumor stage. The data emphasize that it is not sufficient to simply address pain during the treatment of patients with cancer pain; a more global approach to symptom management is necessary.

Basic guidelines for cancer pain treatment can be found in many different handbooks published in the last years. Particularly those of the World Health Organisation published in 1986 and revised in 1996, furnish useful indication for cancer pain treatment. The authors therefore focused on resuming the most recent development in this field. In the research regarding alternative routes of administration of opioids in alternative to the oral route, the rectal administration of morphine and methadone and the transdermal route for fentanyl have proved to be efficacious. The subcutaneous route (for morphine) as well as the intravenous, peridural and subaracnoid routes, being known for some time are not taken in consideration in this paper. Various studies suggest that alternative routes are necessary in 53-70% of patients in their last days or months of live. The most frequent causes for the need to stop oral administration are dysphagia, nausea, and uncontrollable vomiting, bowel obstruction, malabsorption, cognitive failure, coma, and pain syndromes requiring anaesthetics which need be administered via the spinal route. Among the drugs, tramadol seems to be effective in the control of moderate pain. Tramadol is a centrally acting analgesic drug; it has an agonist effect on mu 1 receptors of opioids and acts also by inhibiting the re-uptake of noradrenaline and serotonine which activates descending monoaminergic inhibitory pathways. Recent clinical studies revealed that pamidronate has an analgesic effect in pain due to bone metastasis. Pamidronate is part of the biphosphonates, which are active on bone metabolism and are usually being used for the treatment of hypercalcaemia in cancer. The authors also describe briefly the indication of ketamin in association with morphine for the treatment of neuropathic pain.

Fentanyl TTS, the only transdermal opioid, represents a real tool for a better quality of life in patients with cancer pain. In this paper we report a short description of the pharmacologic properties and administration procedures of this drug that is a useful alternative when other opioids recommended on the third step of the WHO analgesic ladder, are ineffective or present unbearable side effects (nausea and/or vomiting-severe mucosites and dysphagia). In particular we indicated some changes and adjustments switching from morphine per os to fentanyl TTS. In addition we report the results of a study carried out in our Pain Therapy Center on 49 patients with severe oncologic pain, previously treated with opioids and other drugs associations. Our results indicated a good control of continuous nociceptive cancer pain, with a better quality of life and lesser side effects to respect the previous regime of orally opioids.

Methadone can be an effective drug for cancer pain but it can also be difficult to use safely. It has been recommended that rotation to methadone from other opioids be undertaken in a hospital setting. The purpose of the study was to characterize the safety, toxicities, and outcomes of outpatient rotation to methadone for severe cancer pain in a heavily pretreated cohort of cancer patients. Data were collected through a retrospective review of consecutive patients from a tertiary level cancer pain clinic. Twenty-nine patients were rotated to methadone, 13 (45%) due to opioid toxicity and 16 (55%) because of either cost or difficulty swallowing their prior opioid. Eleven of 29 patients (38%) failed methadone due to rapidly progressive cancer, dose-limiting side effects, or other reasons, but the other patients were successfully rotated to methadone. Pain usually improved following rotation to methadone, but drowsiness from methadone was common. On average, it took 32 days to successfully rotate to methadone in the outpatient setting. Cancer patients with advanced disease and severe pain can be safely and effectively rotated to methadone in the outpatient setting. It takes considerably longer to stabilize these patients than patients on lower doses of opioid or those titrated in the inpatient setting. A careful monitoring system is needed to screen for evidence of toxicity.

Most patients with advanced cancer develop diverse symptoms that can limit the efficacy of pain treatment and undermine their quality of life. The present study surveys symptom prevalence, etiology and severity in 593 cancer patients treated by a pain service. Non-opioid analgesics, opioids and adjuvants were administered following the WHO-guidelines for cancer pain relief. Other symptoms were systematically treated by appropriate adjuvant drugs. Pain and symptom severity was measured daily by patient self-assessment; the physicians of the pain service assessed symptom etiology and the severity of confusion, coma and gastrointestinal obstruction at each visit. The patients were treated for an average period of 51 days. Efficacy of pain treatment was good in 70%, satisfactory in 16% and inadequate in 14% of patients. The initial treatment caused a significant reduction in the average number of symptoms from four to three. Prevalence and severity of anorexia, impaired activity, confusion, mood changes, insomnia, constipation, dyspepsia, dyspnoea, coughing, dysphagia and urinary symptoms were significantly reduced, those of sedation, other neuropsychiatric symptoms and dry mouth were significantly increased and those of coma, vertigo, diarrhea, nausea, vomiting, intestinal obstruction, erythema, pruritus and sweating remained unchanged. The most frequent symptoms were impaired activity (74% of days), mood changes (22%), constipation (23%), nausea (23%) and dry mouth (20%). The highest severity scores were associated with impaired activity, sedation, coma, intestinal obstruction, dysphagia and urinary symptoms. Of all 23 symptoms, only constipation, erythema and dry mouth were assessed as being most frequently caused by the analgesic regimen. In conclusion, the high prevalence and severity of many symptoms in far advanced cancer can be reduced, if pain treatment is combined with systematic symptom control. Nevertheless, general, neuropsychiatric and gastrointestinal symptoms are experienced during a major part of treatment time and pain relief was inadequate in 14% of patients. Cancer pain management has to be embedded in a frame of palliative care, taking all the possibilities of symptom management into consideration.

(1) For the treatment of cancer pain resistant to WHO step I and II analgesics, several oral morphine preparations are available, in immediate-release and sustained-release formulations. (2) A sustained-release form of oxycodone, an old opiate, was marketed in France in 2002 for oral treatment of cancer pain, in two daily doses. (3) The results of three comparative double-blind trials suggest that 1 mg oxycodone is similarly effective to 1.5 mg of morphine. According to another comparative double-blind trial, 1 mg oxycodone has about the same analgesic efficacy as 0.25 mg of hydromorphone. (4) Oxycodone has the usual opiate side effects including constipation, sedation, nausea and vomiting, and pruritus. (5) Oxycodone has not been tested in comparative trials in patients in whom morphine is ineffective or poorly tolerated. (6) The available product range of sustained-release oxycodone does not allow the dose to be adjusted rapidly at the outset of treatment, and is poorly suited to patients who have difficulty swallowing. (7) In practice, oral morphine remains the reference treatment for cancer pain resistant to WHO step I and II analgesics.

Pain control in patients with cancer represents a significant aspect of radiation therapy practice. Radiation therapy is one of the most effective, and often the only, therapeutic option to relieve pain caused by nerve compression or infiltration by malignant tumor, pain from liver and bony metastases and it provides also successful palliation of dysphagia caused by oesophageal carcinoma and of pain due to pancreatic cancer. Various instruments are avaliable for pain evaluation but a valid methodology to assess the pain status in the patient with cronic cancer pain is still an important clinical problem. In this complex and wide scene this contribution wants to confirm the role of radiotherapy in cancer pain control, in paricular in bone metastases, and to involve the patient himself in the survey of radiation treatement response by a subjective evaluation of bone pain, elaborating a reliable and valid unidimensional method by which recording the self-rating of the patient's sensation. Materials and Methods For the subjective evaluation of pain caused by bone metastases we used an application form with which drawing information in the course of time in terms of: response to the treatment, duration of symptom relief and quality of life. Results Considering as cut-off a dose of 30 Gy, which is commonly considered the conventional treatment for bone metastases, the partial and complete response were, respectively, of 54% and 30% in the patients treated with dose higher than or equal to 30 Gy, and 60% and 20% in the ones treated with doses lower than 30 Gy. In the whole, in 84 patients, the global response was of 82%, in accordance with literature. Conclusion In this retrospective study, the analysis of patient's subjective experience confirmed the effectiveness of radiotherapy in reducing pain caused by bone metastases and in improving quality of life of the patient himself. Given the conflicting opinions on low-dose short-course radiotherapy versus prolonged or higher dose schedules on initial pain relief, we are going to define categories of homogenous patients on whom starting treatment schedules with the aim or of palliation of the symptom or of the functional restitutio, on the base of the expectation and the quality of life.

Oral medication is the simplest way in treatment of chronic pain. For cancer pain oral analgesics are efficacious in more than 90% of the patients. When a causal therapy of pain (e.g. chemotherapy, operation) fails an analgesic ladder with oral analgesics is instituted. This ladder starts with a non-narcotic analgesic in a sufficient dose. The regular dose of acetylsalicylic acid or paracetamol is 4 g daily. When this dose does not work sufficiently, a weak opioid (e.g. dihydrocodeine) is given concomitantly at an individual dose. When the weak opioid fails, strong opioids are given (e.g. morphine). The drugs should be given by mouth whenever possible. The most important point is the regular application according to a time-schedule. This time-schedule is related to the action time of the drug. Patients with severe vomiting or dysphagia can receive a continuous subcutaneous infusion. These measures are based on recommendations of the WHO.The same medications can be employed in patients with chronic non-malignant pain, provided that all other conventional measures in pain treatment fail. However, many states of pain are not opioid-responsive. Pain related to the sympathetic nervous system is more responsive to antidepressants than to opioids or NSAID. Neuropathic pain as in trigeminal neuralgia responds to anticonvulsants. Pain from muscle spasm is better controlled by muscle relaxants than by analgesics. Bone pain is more sensitive to NSAID than to any other drug.In any state of pain the response to the different groups of drugs should be evaluated first. Then a stepwise pharmacological approach should be performed. In most cases pain can be treated effectively by oral drugs.

Patients with chronic pain often develop dysphagia during the course of an advanced disease such as cancer. Opioids are the cornerstone of the management of cancer pain and are commonly administered orally. However, the oral route does not suit patients with dysphagia, who require alternative methods to administer analgesic drugs. Opioids given by parenteral or transdermal routes provide adequate pain control, being at least as efficacious as the oral route, but knowledge and experience in conversion ratios are mandatory when using these routes of administration. For breakthrough pain, transmucosal fentanyl preparations should be the preferred option and these can be given as needed due to the route of absorption. In addition, a new class of opioid formulations has been developed for use in dysphagic patients that are administered via nasogastric or enteral tubes while maintaining their sustained-release properties.
