- BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.

- We studied the effect of postoperative radiotherapy (RT) after breast sector resection for ductal carcinoma in situ (DCIS). The study protocol stipulated radical surgery but microscopically clear margins were not mandatory. We randomised 1,046 operated women to postoperative RT or control between 1987 and 1999. The primary endpoint was ipsilateral local recurrence. Secondary endpoints were contralateral breast cancer, distant metastasis and death. After a median follow-up of 5.2 years (range 0.1-13.8) there were 44 recurrences in the RT group corresponding to a cumulative incidence of 0.07 (95% confidence interval (CI) 0.05-0.10). In the control group there were 117 recurrences giving a cumulative incidence of 0.22 (95% CI 0.18-0.26) giving an overall hazard ratio of 0.33 (95% CI 0.24-0.47, p < 0.0001). Twenty two percent of the patients had microscopically unknown or involved margins. We found no evidence for different effects of RT on the relative risk of invasive or in situ recurrence. Secondary endpoints did not differ. Women undergoing sector resection for DCIS under conditions of population based screening mammography benefit from postoperative RT to the breast. Seven patients needed RT-treatment to prevent one recurrence.

Quality improvement in palliative care : the role of a national quality register and perceptions of information during palliative chemotherapy
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- IntroductionThere is a need in palliative care for development of structured methods to assess quality and support improvement. This need is present both within and outside specialised palliative care.Honest information from physicians is regarded as an important part of palliative care. Information about the transition to end-of-life care (ITEOL), conveyed by physicians to patients, has also been described as a ‘breakpoint conversation’.Quality registers enable monitoring and improvement of quality of care, and clinical research. The Swedish Register of Palliative Care (SRPC) is a Swedish national quality register that collects data from hospitals, hospices, nursing homes and home care, with an end-of-life questionnaire (ELQ) about palliative care content focusing on the last week of life.AimsStudy I – The aim was to examine the validity of the ELQ from the SRPC.Study II – The aim was to examine whether participation in the SRPC increases the quality of palliative care over a three-year period regarding eight items in the ELQ.Study III – The aim was to examine whether an educational intervention for physicians and nurses in nursing homes and hospitals increases the proportion of patients who receive ITEOL.Study IV – The aim was to describe how patients with cancer perceive the information they receive from physicians during palliative chemotherapy.MethodsStudy I – Data from 100 medical records and data from the paper versions of the ELQ filled in at a specialised palliative unit were compared with data reported to the SRPC.Study II – Data from eight items in the ELQ reported to the SRPC from all healthcare units that had reported patients continuously during a three-year period were compared year-by-year with logistic regression.Study III – Two municipalities (in charge of nursing homes) and two hospitals were randomised to receive an interactive half-day course about ITEOL for physicians and nurses. Four hospitals and four municipalities were assigned matched controls. The proportion of patients who received ITEOL before and after the intervention was measured with the ELQ. The effect of the intervention was analysed with a multivariable logistic regression model.Study IV – Fifteen semi-structured interviews with patients with incurable cancer were conducted, transcribed verbatim and analysed with qualitative content analysis.ResultsStudy I – The questions in the ELQ showed a congruity of 22% to 100% when comparing data from medical records with data reported to the SRPC. Eight questions fell below 80%. The paper versions filled in at the unit and the data reported to the SRPC showed a congruity of between 91% and 100%.Study II – The prevalence of six symptoms decreased. The prescription of PRN (pro re nata – ‘as needed’) medications for pain, nausea, anxiety and death rattle increased. A higher proportion of patients died in their place of preference. The patient’s next of kin was more often offered a follow-up appointment after the patient’s death. There was no change in the proportion of patients or next of kin who received ITEOL.Study III – The proportion of patients in the intervention group who received ITEOL increased from 35.1% (during a six-month period before the intervention) to 42.0% (during a six-month period after the intervention). The proportion in the control group increased from 30.4% to 33.7%. The effect of the intervention was significant (p=0.005) in the multivariable model.Study IV – Three categories were disclosed during the analytical process: ‘living with a death sentence’, ‘depending on chemotherapy’, and ‘living with uncertainty’.ConclusionsA national quality register has the potential of contributing to quality improvement in palliative care. Study I showed varied validity in the ELQ, implying a need to modify the questionnaire. Study II showed that participation in the SRPC was covariant with quality improvements in end-of-life care over time. Study III showed that more patients received ITEOL after an educative half-day intervention directed to physicians and nurses. Study IV showed that patients undergoing palliative chemotherapy perceived that their disease was incurable and deadly, and that conditions for future treatment and survival were uncertain.

- Aims: The reported long waiting times for cancer patients have mostly been related to prognostic outcome and less to patient-related experience to outcome. We assessed waiting times for patients with cancer of the breast, prostate, colon or rectum in Sweden.Methods: The median time from referral to start of treatment was assessed using data from clinical cancer registers for patients who received curative treatment during 2011, 2012 and 2013.Results: The median overall waiting time in different counties ranged from 7 to 28 days for breast cancer, from 117 to 280 days for prostate cancer, from 27 to 64 days for colon cancer and from 48 to 80 days for rectal cancer. For the entire nation, the median time from referral to start of treatment remained unchanged from 2011 to 2013 for each cancer diagnosis.Conclusions: Large variations were found in waiting times between different counties in Sweden and between different types of cancer. The long waiting times identified in this study emphasize the need to improve national programmes for more rapid diagnosis and treatment.

- Purpose Four randomized studies show that adjuvant radiotherapy (RT) lowers the risk of subsequent ipsilateral breast events (IBEs) after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS) by approximately 50% after 10 to 15 years. We present 20 years of follow-up data for the SweDCIS trial. Patients and Methods Between 1987 and 1999 1,046 women were randomly assigned to RT or not after BCS for primary DCIS. Results up to 2005 have been published, and we now add another 7 years of follow-up. All breast cancer events and causes of death were registered. Results There were 129 in situ and 129 invasive IBEs. Absolute risk reduction in the RT arm was 12.0% at 20 years (95% CI, 6.5 to 17.7), with a relative risk reduction of 37.5%. Absolute reduction was 10.0% (95% CI, 6.0 to 14.0) for in situ and 2.0% (95% CI, -3.0 to 7.0) for invasive IBEs. There was a nonstatistically significantly increased number of contralateral events in the RT arm (67 v 48 events; hazard ratio, 1.38; 95% CI, 0.95 to 2.00). Breast cancer-specific death and overall survival were not influenced. Younger women experienced a relatively higher risk of invasive IBE and lower effect of RT. The hazard over time looked different for in situ and invasive IBEs. Conclusion Use of adjuvant RT is supported by 20-year follow-up. Modest protection against invasive recurrences and a possible increase in contralateral cancers still call for a need to find groups of patients for whom RT could be avoided or mastectomy with breast reconstruction is indicated.
