Prevalence and impact of constipation and bowel dysfunction induced by strong opioids: a cross-sectional survey of 520 patients with cancer pain: DYONISOS study.

OBJECTIVE: To describe the prevalence of opioid-induced constipation (OIC) in patients with cancer pain according to the Knowles-Eccersley-Scott symptom score (KESS), the different symptoms of opioid-induced bowel dysfunction (OIBD), and to assess the impact of OIBD on patient's quality-of-life. METHODS: A cross-sectional observational study, using the KESS questionnaire and the physician's subjective assessment of constipation, and other questionnaires and questions on constipation, OIBD, and quality-of-life, carried out on 1 day at oncology day centres and hospitals. RESULTS: Five hundred and twenty patients were enrolled at 77 centres in France; 61.7% of patients (n = 321) showed a degree of constipation that is problematic for the patient according to KESS (between 9-39). Even more patients, 85.7% (n = 438), were considered constipated according to the physician's subjective assessment-despite laxative use (84.7% of patients). Quality-of-life was significantly reduced in constipated vs non-constipated patients for both PAC-QoL (p < 0.0001 for total score and each dimension) and the SF-12 questionnaires (statistically significant for all dimensions except physical state and role physical). OIC and OIBD led to hospitalization (16% of patients), pain (75% of patients), and frequent changes in opioid and laxative treatment. KEY LIMITATIONS: This cross-sectional study, in a selected population of cancer patients, has measured prevalence and impact of OIBD. Further confirmation could be sought through the use of longitudinal studies, and larger populations, such as non-cancer pain patients treated with opioids. CONCLUSIONS: Cancer patients taking opioids for pain are very frequently constipated, even if they are prescribed laxatives. This leads to relevant impairments of quality-of-life.

Doubling of the epirubicin dosage within the 5-fluorouracil, epirubicin and cyclophosphamide regimen: a prospective, randomized, multicentric study on antitumor effect and quality of life in advanced breast cancer.

In metastatic breast cancer (MBC) doubling the epirubicin (EPI) dose intensity (DI) within the FEC (5-fluorouracil, EPI, cyclophosphamide) regimen could increase the response rate (RR) and ameliorate the quality of life (QoL) over standard FEC. From May, 1995, 74 consecutive patients with MBC were randomly treated with 6 courses of two FEC regimens containing 60 (60FEC) or 120 (120FEC, supported by primary G-CSF) mg/m2 of EPI. Drugs were administered every 21 days. The QoL was assessed over and after treatment by the EORTC QLQ-C30 (VER 2.0) and QLQ-BR23 questionnaires, compiled by the patient, and the Spitzer's QL-index, compiled by the physician. The study was prematurely closed in May, 1997, due to RR and QoL data of 4th interim analysis. The delivered EPI DI was 20.0 and 37.9 mg/m2/week in 60- and in 120FEC, respectively. Among the two regimens, there was no statistically significant difference in RR or in improvement of baseline overall QoL. With respect to 60FEC patients, the 120FEC patients had longer time to progression (19.2 vs 13.1 mos, p=0.04). Over baseline, the 120- but not the 60FEC patients had significantly greater pain decrease and lower deterioration of body image. In MBC, both 60- and 120FEC regimens furnished the same RR and improvement in overall baseline QoL. With respect to 60FEC patients, the 120FEC patients experienced longer time to progression. Over baseline, pain decrease and preservation of body image were also greater in these patients.

Metastatic endometrial adenocarcinoma to the skin of a toe.

A 55-year-old woman had a history of prolonged vaginal bleeding. Dilatation and curettage confirmed poorly differentiated endometrial adenocarcinoma. After hysterectomy, salpingo-oophorectomy, and 5,040 cGy of postoperative irradiation, lung metastases developed, which temporarily responded to chemotherapy that included adriamycin and cisplatin. Metastatic lesions developed later in the left acetabulum and the hallux. The latter, clinically reminiscent of pyogenic granuloma, affected only skin. The poorly differentiated toe metastasis duplicated areas of the primary endometrial adenocarcinoma and was immunohistochemically similar to it. While appearing quite rarely, and generally late in the disease, pedal skin lesions may represent metastases from known or occult visceral cancers.

A common source outbreak of gastroenteritis in a teaching hospital.

An outbreak of gastroenteritis at a large teaching hospital affected at least 52 workers. Investigation implicated a tuna salad, and the circumstances suggested Clostridium perfringens as the etiologic agent. The risk of such outbreaks may be reduced by cooling of ingredients prior to mixing and refrigeration in small steel containers.
