- A group of Swedish radiation oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy in a facility where one of the principal aims is to facilitate randomized and other studies in which the advantage of protons can be shown and the magnitude of the differences compared with optimally administered conventional radiation treatment, also including intensity-modulated radiation therapy (IMRT) and brachytherapy, can be shown. The estimations have been based on current statistics of tumour incidence in Sweden, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours together with information on normal tissue complication rates. In Sweden, it is assessed that between 2200 and 2500 patients annually are eligible for proton beam therapy, and that for these patients the potential therapeutic benefit is so great as to justify the additional expense of proton therapy. This constitutes between 14-15% of all irradiated patients annually.

Forskningsöversikt (refereegranskat)abstract
- This report by The Swedish Council on Technology Assessment in Health Care (SBU) reviews, classifies, and grades the scientific literature on cancer chemotherapy in some major tumour types, describes the practice of chemotherapy in Sweden, compares practice with scientific knowledge, and analyses the costs and cost-effectiveness of chemotherapy. The report is intended primarily for decision-makers at various levels, both practitioners and administrators. It is also of interest for the medical profession. The extensive body of scientific literature was reviewed according to strict criteria that reflected the scientific weight of the literature. Sixteen experts representing different disciplines (oncology, surgery, internal medicine, health economy and quality of life research) participated in the literature review. Each section was discussed within the project group and was reviewed by at least one, but usually two international researchers. Additional input was provided by national experts representing different scientific disciplines. For the final evaluation to be as close to the objective truth as possible, a concerted effort was made to guarantee objectivity and thorough assessment of current knowledge about the effects of chemotherapy on the selected cancers. The tumour types selected for this assessment include firstly those types where three investigations had shown an increased use of chemotherapy in Sweden during the latest decade. These were non-small cell lung cancer (NSCLC), gastric cancer, pancreatic cancer, colorectal cancer and urinary bladder cancer. Secondly, the two tumour types comprising the greatest number of patients treated with chemotherapy in Sweden, breast cancer and haematological malignancies, were included. Among the haematological malignancies, the most prevalent ones, acute myeloid leukaemia (AML), chronic lymphocytic leukaemia (CLL), Hodgkin's disease (HD), aggressive non-Hodgkin's lymphoma (NHL) of the large B-cell type and indolent NHL of follicular type were evaluated. These constitute about 75%, of all haematological malignancies. Thirdly, ovarian cancer was included since chemotherapy has been extensively used and since, at the time of the planning of this overview, a group of very expensive drugs, the taxanes, had preliminarily shown promising results. A wealth of scientific literature has been published on cancer therapy. The review presented in this report is limited to scientific studies judged to be important for evaluating chemotherapy efficacy. Assessments of the content and quality of these studies, and a critical summary of the results in all stages of the selected tumours, have never before been attempted in this way. However, similar comprehensive overviews of certain stages of the tumours have previously been made. These overviews were also critically evaluated. Totally 1,496 studies involving 558,743 patients were reviewed. The survey of practice of chemotherapy use involved all departments of surgery, urology, gynaecology, internal medicine including haematologic units, pulmonary medicine and general and gynaecologic oncology at 16 hospitals in two health care regions in Sweden, covering 39% of the Swedish population. During the 4 weeks of the survey, all patients with the diagnoses concerned who received chemotherapy were registered. The study included 1,590 patients. The working group's general conclusions are summarised in the following points: The literature on the effects of chemotherapy is extensive. Chemotherapy has a well-documented role in the curative and palliative treatment of patients with several types of cancer. The use of chemotherapy is of utmost importance for the possibility of cure in certain tumour types. In other tumours, chemotherapy increases the possibility of cure when added to local and regional treatments, particularly surgery. In the instances of no possibility of cure, chemotherapy may to a variable extent improve both patient survival and well-being. In Sweden chemotherapy is largely used in accordance with that documented in the scientific literature. The extent of both over- and under-treatment seems to be limited but cannot be excluded at the individual patient level. The literature-based knowledge is scientifically of lower quality in the most chemotherapy sensitive tumours than in tumours showing more limited sensitivity. In the more sensitive tumours, positive effects on a symptomatic stage and survival were seen several decades ago. In those days, clinical treatment studies did not fulfil the current high quality requirements. Small life-prolonging effects of chemotherapy are sometimes very well documented in large, high quality scientific studies. Some of these s

Tidskriftsartikel (refereegranskat)abstract
- In Sweden a National Care Programme provides treatment principles for Hodgkin's lymphoma (HL) since 1985, for early and intermediate stages often less extensive than international recommendations. The purpose is to evaluate long-term results of these principles. A total of 308 patients (167 men and 141 women), 17-59 yr old (median 31), diagnosed during 1985-92, pathological stage (PS) I-III1A and I-IIB and clinical stage (CS) I-IIA, mean follow-up 8.8 yr, were studied. Staging laparotomy was recommended in CS IIA. Recommended treatment was mantle or mini-mantle radiotherapy (RT) alone in CS IA, and PS I-IIA and subtotal nodal irradiation in PS III1A if the disease was not bulky. Patients in PS I-IIA and III1A with bulky disease, and PS I-IIB received one cycle of mechlorethamine, vincristine, prednisone, procarbazine/doxorubicin, bleomycin, vinblastine, lacarbazine (MOPP/ABVD) before irradiation. The remaining patients received three to four cycles of MOPP/ABVD with RT to bulky disease. Relapse-free (RFS), Hodgkin specific (HLS), and overall survival (OS) at 10 yr were 74%, 92% and 85%. In the individual stages, RFS ranged from 53% (PSIII1A) to 90% (PS IA). RFS (P = 0.006), HLS, and OS were significantly better in patients treated with chemotherapy compared with those treated with RT alone, especially in patients with bulky disease (P = 0.0005). The international prognostic score did not provide any prognostic information. The OS rates are in agreement with results from international centres during that time. The recommended treatment was sufficient to produce the desired results of <20-30% recurrences, except in PS III1A. Most relapses could be salvaged. Patients with risk factors treated with one MOPP/ABVD and RT had an excellent outcome, superior to those without risk factors treated with RT alone. These results favour the trend to treat early and intermediate stages with a short course of chemotherapy followed by limited RT.

Tidskriftsartikel (refereegranskat)abstract
- To evaluate the efficacy and safety of Navoban (tropisetron) three different Nordic multicentre trials were conducted during the period 1988-92. In all, 1050 patients were recruited from 15 centres. In the first study, Navoban monotherapy was compared with a high-dose metoclopramide cocktail. In the second, Navoban +/- dexamethasone was evaluated for those patients not fully protected by Navoban alone. In the third trial, Navoban was evaluated for various chemotherapy regimens, for long-term efficacy, and for various risk groups of patients. Spontaneous intercycle variations were also evaluated. Navoban was found to be as effective as the antiemetic cocktail but with a more favourable spectrum of side effects and a simpler schedule of administration. Navoban was more effective during the acute than the delayed phase. Addition of dexamethasone significantly improved prevention of both acute and delayed emesis. Long term efficacy seemed to be stable up to 10 cycles of chemotherapy. Patients treated with noncisplatin regimens showed significantly higher protection rates than patients treated with cisplatin. Various cancer diagnoses and cytostatic agents were also evaluated. Gender and age were important risk factors. Navoban was found to be an efficacious antiemetic agent, especially regarding acute nausea and vomiting. Addition of a corticosteroid significantly improved the effect during highly emetogenic chemotherapy. The role of Navoban for delayed emesis must be evaluated in future trials. The two most common side effects were headache and constipation. Overall, Navoban was well tolerated and patient compliance with the drug was high.
