Individual psychosocial support for breast cancer patients : Quality of life, psychological effects, patient satisfaction, health care utilization and costs
- 2007

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A randomized intervention study, with the aim to compare the effects of individual psychosocial support provided by (1) oncology nurses specially trained in psychological techniques (INS), or (2) psychologists (IPS), to (3) standard care (SC). Breast cancer patients, living in Uppsala County, and about to start adjuvant treatment at the Department of Oncology, Uppsala, were consecutively included between 1998 and 2000. The patients were assessed seven times during two years by self-administered questionnaires. Study I revealed positive effects of both INS and IPS as compared to SC on global quality of life, side effects, and post-traumatic distress. A lower proportion of patients in the intervention groups had psychosocial support provided in routine care compared with the SC group. In study II the patients reported being highly satisfied with the intervention, irrespective of profession providing the support. However, patients in the INS group reported higher levels of benefit regarding disease-related problems than those in the IPS group. In study III total Health Care costs were lower in the intervention groups and since a gain in quality-adjusted life years (QALY) was seen (mean .1 QALY), the interventions dominated. The costs for the interventions were 44 291- 48 978 SEK. In study IV, daily reporting of anxiety, depression and activity on Visual Analogue Scales (VAS) were completed during two weeks before and after the Hospital Anxiety and Depression Scale (HADS) assessments. A point assessment with the HADS captured the situation better than four weeks assessment on three VAS in the diary. The HADS was considered preferable to the diary. The conclusion is that psychosocial support is beneficial for breast cancer patients and that the intervention delivered by nurses was as effective as that given by psychologists. The costs for the interventions were limited.

Cancer of the Colon and Rectum : Population Based Survival Analysis and Study on Adverse Effects of Radiation Therapy for Rectal Cancer
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Swedish Cancer Register was used to determine the relative survival rate in colon and rectal cancer and to estimate the occurrence of second cancers related to radiation therapy for rectal cancer. The Swedish Hospital Discharge Register and hospital records were used to estimate the rate of late adverse effects due to radiation therapy for rectal cancer. The whole Swedish population was the source of the survival studies. Patients participating in the Uppsala Trial and the Swedish Rectal Cancer Trial on radiation therapy for rectal cancer constituted the subjects of the studies on late adverse effects and second cancers.The main results of the survival analysis revealed a significant improvement in the 5-year relative survival rate for both colon and rectal cancer. During the time period 1960-1999, the survival improved from 39.6% to 57.2% in colon cancer and from 36.1% to 57.6% in rectal cancer.Patients irradiated for rectal cancer, in addition to surgery, were at increased risk for a second cancer compared to those treated by surgery alone. This risk increase was mainly found for cancers developing in organs within or adjacent to the irradiated target (relative risk (RR) 2.04; 95% confidence interval (CI) 1.10–3.79). Furthermore, the most important late adverse effects of radiation therapy seem to be those on the gastrointestinal tract, in the form of small bowel obstruction (RR 1.88; 95%CI 1.10–3.20) and abdominal pain (RR 1.92; 95% CI 1.14–3.23). Overall, the benefit of radiation therapy was greater than its drawbacks, as a large reduction in local recurrences and better survival was noted in patients treated preoperatively with irradiation for rectal cancer.In conclusion, significant improvements in the survival of patients with colon and rectal cancers have occurred in the last decades, especially in patients with rectal cancer. These improvements probably are related to advances in surgical and adjuvant treatment. The radiation therapy has several drawbacks, however, including an increased risk of second cancers and of bowel obstruction. This emphasises the need to further improve the radiation technique and to select only those patients for radiation therapy who are most likely to benefit from it.

Factors Influencing Selection of Treatment for Colorectal Cancer Patients
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In Sweden and elsewhere there is evidence of poorer cancer survival for patients of low socioeconomic status (SES), and in some settings differences in treatment by SES have been shown.The aim of this thesis was to explore factors which influence cancer treatment decisions, such as knowledge reaped from clinical trials, patient-related factors, and physician-related factors. In a register study of colorectal cancer, all stages, patients were stratified for SES-factors. Differences were seen with regards to clinical investigation, surgical and oncological treatment and survival, with the highly educated group being favored. Survival was better for highly educated patients in stages I, II and III but not in stage IV.In a Scandinavian cohort of newly metastasized colorectal cancer patients, recruitment to clinical trials was studied. Patients entering clinical trials had better performance status and fewer cancer symptoms than those who were treated with chemotherapy outside of a clinical trial. Median survival was 21.3 months for trial-patients and 15.2 months for those treated with chemotherapy outside a trial. Those not treated with chemotherapy had a median survival of just 2.1 months. Patients in clinical trials are highly selected and conclusions drawn from studies cannot be applied to all patients.In the same cohort, treatment and survival were stratified for education, smoking and indicators of social structure. Highly educated patients did not have a survival advantage. Patients who lived alone were offered less combination chemotherapy and surgery of metastases than other patients and had 4 months shorter survival than those who lived with a spouse or child. In a fourth study, 20 Swedish gastrointestinal oncologists were interviewed on which factors they considered when deciding on oncological treatment. Oncologists feared chemotherapy complications due to lack of social support, and ordered less combination chemotherapy for patients living alone. Highly educated patients were seen as well-read and demanding, and giving in to these patients’ requests for treatment was regarded as a way of pleasing patients and relatives and of avoiding conflict.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- OBJECTIVE: The effect of alcohol intake on risk of NHL is unclear. We therefore conducted a population-based case-control study to examine the association between alcohol and NHL risk. METHODS: 613 NHL cases and 480 population controls in Sweden reported their average consumption of beer, wine, and liquor 2 years before the study. Unconditional logistic regression was used to estimate the odds ratios (OR) and corresponding 95% confidence intervals (CI) for associations between alcohol intake and NHL risk. RESULTS: Intake of total alcohol, beer, wine, or liquor was not associated with risk of overall NHL. There was no difference in risk of NHL among those who habitually consumed above 19.1 g of ethanol per day, compared to those who consumed on average 0-2.2 g of ethanol per day (OR = 1.2 (95% CI: 0.8, 1.7); Ptrend = 0.29). However, the association was significantly positive among males (OR = 1.8 (95% CI: 1.1, 2.9); Ptrend = 0.06). Total alcohol, beer, wine, or liquor intake was not associated with any major histopathologic subtype of NHL examined, apart from an association between high wine consumption and increased risk of chronic lymphocytic leukemia. CONCLUSIONS: Alcohol does not appear to be a major etiologic factor for overall NHL, nor its common subtypes.
