- The aim of this study was to investigate the information needs among patients with ovarian cancer and whether these information needs change over time. The information needs were evaluated three times, through structured interviews, and were based on the paired comparison approach developed by Degner and colleagues. A consecutive sample of patients (n=82) with recently diagnosed ovarian cancer was asked to participate.Sixty-four patients (78%) chose to participate. The three different measurements of participants' information needs revealed only small changes in these needs. The three most important information needs, in all measurements, were information about the likelihood of cure, information about the stage and spreading of the disease, and information about different treatment options. Information regarding sexual attractiveness was the lowest ranked item in all measurements. Regarding subgroups (age, education) the only significant difference throughout all measurements was that younger patients rated issues of sexual attractiveness higher than older patients (p=0.005).In this longitudinal study patients with ovarian cancer ranked information about the disease and its treatment (i.e. likelihood of cure, stage of disease, and treatment options) highest, and information about psychosocial aspects and self-care lowest. These findings are in accordance with the results from studies of women diagnosed with other types of cancer, which used the same methodology. © 2004 Elsevier Ltd. All rights reserved.

- In order to survey the side effects after cancer treatment, quality of life data were collected from females in clinical remission. MATERIALS AND METHODS The study was cross-sectional; every patient that visited the outpatient clinic during a period of three months was asked to anonymously complete the EORTC QLQ-C30 questionnaire and five additional specific questions related to gynaecological cancer. RESULTS In total, 235 patients (90%) returned the questionnaire. In general, both the levels of functioning and symptomatology were time-dependent. Patients with short treatment-free intervals reported more problems than the others. When using treatment modality as an independent variable in the statistical calculations, a treatment-related effect on functioning and symptomatology was demonstrated (p < 0.05 to p < 0.001). Patients previously treated with chemotherapy had poorer role- and cognitive functioning and more problems with fatigue, nausea, vomiting, dyspnoea, constipation and financial problems, compared with those not treated with chemotherapy (p < 0.05 to p < 0.01). Those patients who had been treated with external radiotherapy and/or brachytherapy had significantly more problems with flatulence and diarrhoea (p < 0.05 to p < 0.001). In conclusion, patients who underwent treatment for gynaecological cancer reported long-term side effects also many years after finishing treatment. The problems where related to treatment modality which should be considered, especially when planning adjuvant treatment.

- Topoisomerase II-alfa (topo IIalfa) is the key target enzyme for the topoisomerase inhibitor class of anti-cancer drugs. In normal cells, topo IIalfa is expressed predominantly in the S/G2/M phase of the cell cycle. In malignant cells, in vitro studies have indicated that the expression of topo IIalfa is both higher and less dependent on proliferation state in the cell. We studied fresh specimens from 50 cases of primary breast cancer. The expression of topo IIalfa in different cell cycle phases was analyzed with two-parameter flow cytometry using the monoclonal antibody SWT3D1 and propidium iodide staining. The expression of topo IIalfa was significantly higher in the S/G2/M phase of the cell cycle than in the G0/G1 phase in both DNA diploid and DNA nondiploid tumors. In 18 of 21 diploid tumors, and in 25 of 29 nondiploid tumors, >50% of the topo IIalfa–positive cells were in the G0/G1 phase. This significant expression of topo IIalfa in the G0/G1 phase of the cell cycle may have clinically important implications for treatment efficacy of topoisomerase II inhibitors.

- AIMS: The aim of this study was to describe variability in compliance to clinical guidelines in colorectal cancer surgery related to hospital structure.METHODS: All patients registered in the databases of the Regional Oncologic Centre, operated upon electively for colon cancer between the start of the register in 1997 until 2000 (n=1771) and for rectal cancer between the start of the register in 1995 until 2000 (n=1841) were selected for analysis.RESULTS: There was no difference in 5-year survival rate between colon and rectal cancer (mean follow-up 2.6 and 3.0 years, respectively; p=0.22). There was a significant difference in frequency of preoperative liver scan depending on hospital category with an increase in colon cancer from 39 to 46% (p=0.02) and in rectal cancer from 42 to 64% (p<0.001). For colon cancer there was no difference, according to hospital category, in quotient sigmoid and high anterior resection to left-sided resection. Furthermore, high anterior resection was more common at university and general district hospitals (8%) compared with district hospitals (4%) (p=0.01). Sphincter-saving surgery was more common at university hospitals and district general hospitals than at district hospitals (low anterior/abdomino-perineal resection quotients 2.3, 2.4 and 1.6, respectively; p<0.001).CONCLUSIONS: Population-based audit forms an appropriate and valuable basis for quality assurance projects. In addition to describing compliance to guidelines and pointing to process steps that can be improved, such investigations may also indicate changes due to scientific development. Linked to case-costing data, such results may form an important basis for decisions about modifications in health care.

- Distressing and positive experiences for adolescents with cancer with regard to being told the diagnosis, receiving chemotherapy and being admitted to the ward, and important aspects of care for adolescents with cancer was investigated. Data were gathered through semi-structured interviews with 23 adolescents and 21 nurses, and analysed by content analysis. The findings indicate that cancer during adolescence is connected with a range of negative experiences such as fears of alienation, fears of altered appearance, fears of dying, and various physical concerns. Positive experiences include positive relations to staff and being well cared for. Important care for adolescents treated for cancer consists mainly of meeting nice, friendly, supportive, and competent staff, who provide them with age-appropriate information. The findings indicate that adolescents with cancer experience a range of negative and positive experiences related to disease and treatment and that good care for adolescents with cancer is a broad, complex, and multidimensional phenomenon.

- The aims of this study were to investigate ‘satisfaction with care’ and its possible relationships to hope, health-related quality of life, anxiety and depression. Eighty-five patients with endocrine gastrointestinal (GI) tumours responded to questionnaires a few days after a hospital visit. ‘Satisfaction with care’ was assessed by the Comprehensive Assessment of Satisfaction with Care (CASC), health-related quality of life by the EORTC QLQ C-30 and anxiety and depression by the Hospital Anxiety and Depression Scale (HADS). Patients’ highest satisfaction scores were obtained for ‘general satisfaction’ and ‘nurses’ and doctors’ technical skills’. The lowest satisfaction was expressed for ‘doctors’ interpersonal skills’, ‘nurses’ communication skills’ and ‘care organization’. Patients reporting a clinically relevant level of anxiety were less satisfied with several care aspects than those reporting less anxiety. Satisfaction with ‘nurses’ communication skills’ and ‘doctors’ interpersonal skills’ was associated with several aspects of health-related quality of life, whereas satisfaction with ‘doctors’ information’, ‘nurses’ technical skills’ and ‘general satisfaction’ was not. Satisfaction with psychosocial aspects of care is related to the psychosocial function of patients with endocrine GI tumours.

- Satisfaction with care may be closely related to quality of life in cancer patients. This evaluation is especially relevant when quality of care is considered. The present study assessed whether equivalent scaling properties could be found in a comprehensive assessment of satisfaction with care (CASC) administered in cancer patients from French, Polish and Swedish oncology settings, in comparison to the scaling properties previously evidenced in the CASC with an Italian sample. A total of 140, 186 and 133 oncology patients were approached in France, Poland and Sweden, respectively. Specific items in the CASC were identified as consistently omitted across country samples. Multitrait scaling analysis on an item-grouping adapted for the French, Polish, Swedish and Italian samples provided excellent internal consistencies and convergent validity estimates. Discriminant validity proved less satisfactory, evidencing overlap between hypothesised care dimensions across country samples. The identification of omitted or overlapping items will lead to the design of a revised CASC version to further test in larger cross-cultural samples.

On the Use of 76Br-labelled Monoclonal Antibodies for PET : Preclinical Evaluation of Halogenated Antibodies for Diagnosis and Treatment of Cancer
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Radioactive substances are used in vivo to localize and characterize malignant tumours, generally by scintigraphic methods. In this context positron emission tomography (PET) in combination with radiolabelled monoclonal antibodies (mAbs) may provide a sensitive and specific method for detection of cancer. Individual dose calculations, based on such PET measurements, may be carried out to predict the possible use of mAbs labelled with therapeutic nuclides. The positron emitter 76Br, with a half-life of 16 h, is a well-suited candidate for radiolabelling and PET imaging. One drawback of radiobromine is that bromide, the ultimate catabolite after degradation of brominated mAb, is only tardily excreted from the body and is evenly distributed throughout the extracellular space, thereby increasing the background radioactivity. The aim of this work was to produce 76Br-mAb preparations with high accumulation and retention in tumour tissue together with a quick clearance of 76Br-labelled catabolites. Furthermore, the possibility to use brominated or iodinated mAbs in combination with PET to predict 211At-mAb dosimetry was evaluated.Monoclonal Abs directed against colorectal cancer were labelled with 76Br using the direct Chloramine-T-method or indirectly by labelling the precursor molecule N-succinimidyl para-(tri-methylstannyl) benzoate with 76Br, which was subsequently conjugated to the mAbs. Monoclonal Ab A33 labelled with 76Br using the two labelling protocols was characterized in vitro and in vivo in a rat tumour xenograft model. The mAb A33 was also labelled with 125I for comparison. In addition, mAb A33 was labelled with 211At, 125I and 76Br using the indirect labelling protocol and the mAb pharmacokinetics was studied in normal rats in order to estimate if data from brominated or iodinated mAb could be used for dosimetry of 211At in healthy organs and tissue.In conclusion, both direct and indirect labelling resulted in high yields and mAbs with preserved immunoreactivity. In vivo characterization of 76Br-brominated mAb A33 showed that the indirect labelling method makes 76Br-brominated mAb A33 a promising candidate for tumour imaging with PET due to the faster excretion of radiolabelled catabolites compared with direct bromination. Finally, mAb A33 labelled with 76Br and 124/125I can be used to predict the 211At dose of astatinated mAb A33 in most organs given that a correction factor is applied for organs with varying uptake.

- Pseudohypoaldosteronism type I (PHA1) is a condition associated with salt wasting leading to dehydration, hypotension, hyperkalemia, and metabolic acidosis. Sporadic cases and two familial forms, one autosomal dominant and one autosomal recessive form, have been described. The autosomal dominant or sporadic form manifests milder salt wasting that remits with age. Mutations in the gene encoding the mineralocorticoid receptor (MR) have been identified in patients with the autosomal dominant inheritance. However, recent studies suggest that the autosomal dominant and sporadic forms are genetically heterogeneous and that additional genes might be involved. We report on the study of 15 members of a Swedish five-generation family with the autosomal dominant form of PHA1. Interestingly, neuropathy was found in two of five affected individuals. A novel heterozygous nonsense mutation C436X in exon 2 was identified in the index patient by linkage analysis, PCR, and direct sequencing of the MR gene. Analysis of the family demonstrated that the mutation segregated with PHA1 in the family. It is unclear whether the neuropathy is associated with the mutation found. Our results together with previously published data suggest that loss-of-function mutations of the MR gene located at 4q31.1, commonly are associated with the autosomal dominant form of PHA1.
