Palliative sedation therapy does not hasten death: results from a prospective multicenter study.

BACKGROUND: Palliative sedation therapy (PST) is indicated for and used to control refractory symptoms in cancer patients undergoing palliative care. We aimed to evaluate whether PST has a detrimental effect on survival in terminally ill patients. METHODS: This multicenter, observational, prospective, nonrandomized population-based study evaluated overall survival in two cohorts of hospice patients, one submitted to palliative sedation (A) and the other managed as per routine hospice practice (B). Cohorts were matched for age class, gender, reason for hospice admission, and Karnofsky performance status. RESULTS: Of the 518 patients enrolled, 267 formed cohort A and 251 cohort B. In total, 25.1% of patients admitted to the participating hospices received PST. Mean and median duration of sedation was 4 (standard deviation 6.0) and 2 days (range 0-43), respectively. Median survival of arm A was 12 days [90% confidence interval (CI) 10-14], while that of arm B was 9 days (90% CI 8-10) (log rank = 0.95, P = 0.330) (unadjusted hazard ratio = 0.92, 90% CI 0.80-1.06). CONCLUSION: PST does not shorten life when used to relieve refractory symptoms and does not need the doctrine of double effect to justify its use from an ethical point of view.

Evaluation of the cost of home care for terminally ill cancer patients.

The aim of this work was to carry out a cost evaluation of the home care programme for terminally ill cancer patients run by the Istituto Oncologico Romagnolo (I.O.R.) in the areas of Forlì, Cesena, Ravenna and Rimini (Romagna, Italy). To determine effective home care direct costs, we first selected 1 week of care as an observation unit. We then proceeded to assess the medical and nursing care units together with the clinical protocols administered for each patient. The Karnofsky Performance Status (KPS) was also assessed weekly. In this way, we calculated care costs for each patient and for each week as the sum of medical costs, nursing costs, treatment costs and other costs. A consecutive series of 574 patients were involved in the study from 1 April 1994 to 31 March 1995. A total of 5164 patient-weeks of care was provided, with an average cost per week of 177.6 Ecu. This weekly cost increased in the last 100 days of life (week -15 = 179.5 Ecu; week -8 = 188.3 Ecu; week -2 = 221.0 Ecu; P < 0.001). When single components were analysed in relation to total cost (treatment protocols, physician and nursing care) the increased global cost was found to be mainly attributable to the intensification in nursing care (21.8% of costs in week -15 vs 27.3% of costs in week -2). Examination of the relation between the cost of 1 week of care and KPS values clearly shows that healthcare costs increased as KPS decreased (from 152.2 Ecu with KPS > or = 60 to 292.6 Ecu with KPS < or = 20; P < 0.001). Home care costs were also seen to vary with some clinical characteristics and symptoms present when patients entered the study: asthenia, anorexia, nausea/vomiting, bedsores. Given the good results of home care for cancer patients in terms of quality of life, this method of cost accounting for home-care providers can help to monitor the rising cost of assistance and confirm the cost effectiveness of this type of care.

A new regimen of cisplatin, epirubicin and methotrexate (PEM-3) as primary chemotherapy for locally advanced bladder cancer.

In this phase II study, 41 patients with locally advanced urothelial bladder cancer (T2-4, N0, M0) were treated with primary chemotherapy (cisplatin, epirubicin, methotrexate: PEM-3). All the patients were assessable for response and toxicity. Clinical monitoring was performed with computerized tomography and cystoscopy. Nineteen clinical complete remissions (46%) and 10 partial remissions (24.5%) were obtained (CR + PR, 70.5%; 95% confidence interval, 57%-85%). Ten patients were considered to have clinically stable disease (24.5%), and 2 patients progressed (5%). Surgery after chemotherapy was performed in 22 cases: in 6 patients (27%) a pathologic complete response was achieved. The pathologic stage was lower than the initial clinical stage in 13 patients (59%). After a median follow-up of 3 years (range, 1-4), the median time to progression was 104 weeks. At this writing, 20 patients, 12 of which were submitted to surgery and 8 were not operated, are disease-free. The 3-year survival rate is 52%. No one had to interrupt the treatment because of toxicity. In conclusion, the PEM-3 regimen is a very active and well-tolerated regimen in locally advanced bladder cancer.

Vascular complications in patients receiving chemotherapy - what role do 3rd-generation antiemetics play.

Vascular diseases in oncology are often attributed to several factors (hospitalisation, paraneoplastic syndrome, probable damaging effect on epithelium by chemotherapeutic agents) however they are reasonably infrequent events. From 7/10/1993 to 21/3/1994 we observed 8 cases of vascular diseases (venous and arterial) of varying intensity in patients receiving anticancer chemotherapy in association with third generation antiemetics. On the basis of similar experiences reported in the literature of patients undergoing chemotherapy and serotonin-antagonist antiemetics, we performed a detailed analysis of these 8 cases. Few-cases of vascular diseases have been observed in phase II and III studies inpatients treated with ondansetron but the physiopathological mechanism is still not well understood. Of our 8 patients, 5 were female and 3 male, with ages ranging from 36 to 73 years. All cases had different types of solid tumors and had been treated with different chemotherapeutic schemes (two containing cisplatin). All the patients had received varying doses (from 16 to 96 mg for 5 days) of ondansetron. Vascular complications occurred 1 to 3 weeks after treatment and 3 cases are still receiving therapy. It can be noted that two patients who had previously been treated with ondansetron did not develop vascular problems. This drug has been in use in our department since May 1991, but problems of a vascular nature only arose in October 1993. At present a final conclusion cannot be reached as to the link between ondansetron and vascular complications.
