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.
