Use of tranquilizers and sleeping pills among cancer patients is associated with a poorer quality of life.

PURPOSE: To evaluate the association between sleeping pill/tranquilizer (SP/T) use and quality of life (QOL) among cancer patients. PATIENTS AND METHODS: Oncology patients (n = 909) in three Israeli hospitals were interviewed in clinics, day centers and in-patient departments regarding SP/T use in the previous week. Crude and adjusted QOL scores, measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30), were compared in users vs. non-users. RESULTS: Sleeping pill/tranquilizer use was self-reported by 234 (25.7%) participants, but rarely documented in medical charts. Factors associated with SP/T use were female gender (adjusted Odds ratio, OR: 1.79; 95% Confidence interval, CI: 1.22-2.62, age (OR: 4.6; 95% CI: 1.66-12.53 for age 70+), place of birth (OR: 1.97; 95% CI: 1.19-3.26 for Eastern Europe compared with Israel), concomitant use of painkillers (OR: 2.88; 95% CI: 1.97-4.20) and presence of cardiovascular disease (OR: 2.41; 95% CI: 1.48-3.91). Controlling these factors as well as disease status, users had a poorer QOL on all functional scales (p < 0.001) as well as global QOL. Furthermore, users reported increased severity of symptoms, especially fatigue, insomnia, pain, dyspnea and constipation (p < 0.01), compared to non-users. CONCLUSIONS: Use of SP/T, reported by one fourth of cancer patients, was associated with substantially poorer QOL and increased severity of symptoms. Causal inference is not possible given the cross-sectional design. Periodic inquiry regarding use of these medications in the Oncology Clinic is recommended since it may identify patients with poor QOL and unmet needs.

Determinants of the use of complementary therapies by patients with cancer.

PURPOSE: We performed a survey of Israeli oncology patients to examine the extent of their use of complementary therapies (CT) and to compare sociodemographic, psychologic, and medical characteristics, attitudes, and quality of life of users and nonusers of CT. PATIENTS AND METHODS: Questionnaires were administered to 1,027 patients attending ambulatory and inpatient hematology or oncology facilities at three hospitals. Medical information was extracted from charts. Univariate and multivariate comparisons of users and nonusers of CT were performed. RESULTS: A total of 526 participants (51.2%) had used CT since their diagnosis, and 357 patients (34.9%) had used CT recently (in the past 3 months). Factors that multivariate analysis found to be significantly associated (P <.05) with recent CT use were as follows: female sex; age 35 to 59 years; more education; coming to the hospital by private car; advanced disease status; having a close friend or a relative with cancer; and attending support groups or individual counseling. After controlling for these factors, individually examined psychosocial variables associated with recent CT use included the following (odds ratios [OR] with 95% confidence intervals [CI]): needs unmet by conventional medicine (OR, 2.76; 95% CI, 1.95 to 3.89); helplessness (OR, 1.39; 95% CI, 1.0 to 1.91); incomplete trust in the doctor (OR, 1.49; 95% CI, 1.08 to 2.06); and changed outlook or beliefs since the diagnosis of cancer (OR, 1.47; 95% CI, 1.07 to 2.02). Functional quality of life (including physical, emotional, social, and role function) and symptom (fatigue and diarrhea) scores were significantly worse for recent CT users compared with nonusers, controlling for age, sex, and current disease status. CONCLUSION: Characteristics associated with CT use include age, sex, education, and advanced disease. Significant associations between CT use and attending supportive psychotherapy, unmet needs, helplessness, and worse emotional and social function indicate considerable distress, suggesting that increased attention to psychosocial needs within oncologic settings is warranted.

Strategies to manage the adverse effects of oral morphine: an evidence-based report.

Successful pain management with opioids requires that adequate analgesia be achieved without excessive adverse effects. By these criteria, a substantial minority of patients treated with oral morphine (10% to 30%) do not have a successful outcome because of (1) excessive adverse effects, (2) inadequate analgesia, or (3) a combination of both excessive adverse effects along with inadequate analgesia. The management of excessive adverse effects remains a major clinical challenge. Multiple approaches have been described to address this problem. The clinical challenge of selecting the best option is enhanced by the lack of definitive, evidence-based comparative data. Indeed, this aspect of opioid therapeutics has become a focus of substantial controversy. This study presents evidence-based recommendations for clinical-practice formulated by an Expert Working Group of the European Association of Palliative Care (EAPC) Research NETWORK: These recommendations highlight the need for careful evaluation to distinguish between morphine adverse effects from comorbidity, dehydration, or drug interactions, and initial consideration of dose reduction (possibly by the addition of a co analgesic). If side effects persist, the clinician should consider options of symptomatic management of the adverse effect, opioid rotation, or switching route of systemic administration. The approaches are described and guidelines are provided to aid in selecting between therapeutic options.

Morphine and alternative opioids in cancer pain: the EAPC recommendations.

An expert working group of the European Association for Palliative Care has revised and updated its guidelines on the use of morphine in the management of cancer pain. The revised recommendations presented here give guidance on the use of morphine and the alternative strong opioid analgesics which have been introduced in many parts of the world in recent years. Practical strategies for dealing with difficult situations are described presenting a consensus view where supporting evidence is lacking. The strength of the evidence on which each recommendation is based is indicated.

New strategies in opioid therapy for cancer pain.

BACKGROUND: The last decade has seen a great increase in the range of opioid agents and formulations available for the treatment of chronic pain, raising new clinical questions and options. METHODS: The author conducted an extensive review of the existing medical literature on opioid agents and formulations currently available. RESULTS: Opioids remain the cornerstone of pharmacotherapy for cancer pain. In addition to severity of pain, coexisting disease, response to previous therapy, the drug's pharmacokinetics and available formulations influence the choice of an opioid agent. Short-half-life drugs, such as morphine, hydromorphone, fentanyl, oxycodone, and oxymorphone, are generally favored initially because they are easier to titrate than long-half-life agents. Long-acting controlled-release opioid preparations can lessen the inconvenience of around-the-clock administration of drugs with a short duration of action. In recent years several new formulations have been developed, including controlled-release morphine suppositories and suspensions; controlled-release tablets of oxycodone, hydromorphone, and codeine; and transdermal fentanyl, a patch that allows 3-day dosing and avoids the first-pass effect of the liver. Most patients who receive controlled-release opioids should be provided with a rescue dose of an immediate-release opioid to treat pain that may break through the controlled-release schedule. CONCLUSIONS: Among the important advances in the last decade in the treatment of chronic pain is the realization that the goals of care and the best means of achieving them differ not only among individuals but often for a single patient throughout a long course of care. Physicians must not only be knowledgeable but also flexible in their approach to managing cancer pain. An understanding of the range of opioid agents and the formulations available can allow physicians to maintain the best possible quality of life for their patients with chronic pain.
