    • I randomiserade studier har det visats att antibiotikaprofylax minskar infektionsfrekvensen med cirka 30–40 procent vid bröstcancerkirurgi.Statens beredning för medicinsk utvärdering rekommenderar därför sedan 2010 antibiotikaprofylax vid bröstcancerkirurgi.I Uppsala läns landsting fick totalt cirka 10 procent postoperativ infektion efter bröstkirurgi under 2009 och 2010. Ingreppets omfattning relaterar klart till risken för infektion.Vi diskuterar i denna artikel när det kan vara indicerat att ge eller inte ge antibiotikaprofylax vid bröstcancerkirurgi.

  • The prognostic role of HER2 expression in ductal breast carcinoma in situ (DCIS); a population-based cohort study
  • 2015

  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Background: HER2 is a well-established prognostic and predictive factor in invasive breast cancer. The role of HER2 in ductal breast carcinoma in situ (DCIS) is debated and recent data have suggested that HER2 is mainly related to in situ recurrences. Our aim was to study HER2 as a prognostic factor in a large population based cohort of DCIS with long-term follow-up. Methods: All 458 patients diagnosed with a primary DCIS 1986-2004 in two Swedish counties were included. Silver-enhanced in situ hybridisation (SISH) was used for detection of HER2 gene amplification and protein expression was assessed by immunohistochemistry (IHC) in tissue microarrays. HER2 positivity was defined as amplified HER2 gene and/or HER2 3+ by IHC. HER2 status in relation to new ipsilateral events (IBE) and Invasive Breast Cancer Recurrences, local or distant (IBCR) was assessed by Kaplan-Meier survival analyses and Cox proportional hazards regression models. Results: Primary DCIS was screening-detected in 75.5 % of cases. Breast conserving surgery (BCS) was performed in 78.6 % of whom 44.0 % received postoperative radiotherapy. No patients received adjuvant endocrine-or chemotherapy. The majority of DCIS could be HER2 classified (N = 420 (91.7 %)); 132 HER2 positive (31 %) and 288 HER2 negative (69 %)). HER2 positivity was related to large tumor size (P = 0.002), high grade (P &lt; 0.001) and ER-and PR negativity (P &lt; 0.001 for both). During follow-up (mean 184 months), 106 IBCRs and 105 IBEs were identified among all 458 cases corresponding to 54 in situ and 51 invasive recurrences. Eighteen women died from breast cancer and another 114 had died from other causes. The risk of IBCR was statistically significantly lower subsequent to a HER2 positive DCIS compared to a HER2 negative DCIS, (Log-Rank P = 0.03, (HR) 0.60 (95 % CI 0.38-0.94)). Remarkably, the curves did not separate until after 10 years. In ER-stratified analyses, HER2 positive DCIS was associated with lower risk of IBCR among women with ER negative DCIS (Log-Rank P = 0.003), but not for women with ER positive DCIS. Conclusions: Improved prognostic tools for DCIS patients are warranted to tailor adjuvant therapy. Here, we demonstrate that HER2 positive disease in the primary DCIS is associated with lower risk of recurrent invasive breast cancer.</p>

  • Time from breast cancer diagnosis to therapeutic surgery and breast cancer prognosis : : a population-based cohort study
  • 2018
  • Ingår i: International Journal of Cancer. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 1097-0215. ; 1104.
  • Tidskriftsartikel (refereegranskat)abstract
    • Theoretically, time from breast cancer diagnosis to therapeutic surgery should affect survival. However, it is unclear whether this holds true in a modern healthcare setting in which breast cancer surgery is carried out within weeks to months of diagnosis. This is a population- and register-based study of all women diagnosed with invasive breast cancer in the Stockholm-Gotland healthcare region in Sweden, 2001 - 2008, and who were initially operated. Follow-up of vital status ended 2014. 7017 women were included in analysis. Our main outcome was overall survival. Main analyses were carried out using Cox proportional hazards models. We adjusted for likely confounders and stratified on mode of detection, tumor size and lymph node metastasis. We found that a longer interval between date of morphological diagnosis and therapeutic surgery was associated with a poorer prognosis. Assuming a linear association, the hazard rate of death from all causes increased by 1.011 (95% CI 1.006 to 1.017) per day. Comparing, e.g., surgery 6 weeks after diagnosis to surgery 3 weeks after diagnosis, thereby confers a 1.26-fold increased hazard rate. The increase in hazard rate associated with surgical delay was strongest in women with largest tumors. Whilst there was a clear association between delays and survival in women without lymph node metastasis, the association may be attenuated in subgroups with increasing number of lymph node metastases. We found no evidence of an interaction between time to surgery and mode of detection. In conclusion, unwarranted delays to primary treatment of breast cancer should be avoided.

  • The Nordic SentiMag trial: a comparison of super paramagnetic iron oxide (SPIO) nanoparticles versus Tc-99 and patent blue in the detection of sentinel node (SN) in patients with breast cancer and a meta-analysis of earlier studies
  • 2016
  • Ingår i: Breast Cancer Research and Treatment. - SPRINGER. - 0167-6806 .- 1573-7217. ; 157:2, s. 281-294
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The aim of the study is to compare the efficacy of SPIO as a tracer in sentinel node biopsy (SNB) in breast cancer with Tc and patent blue in a multicentre prospective study and perform a meta-analysis of all published studies. It also aims to follow skin discoloration after SPIO injection and describe when and how it resolves. Totally 206 patients with early breast cancer were recruited. Tc and patent blue were administered in standard fashion. Patients were injected with SPIO (Sienna+) preoperatively. SNB was performed and detection rates were recorded for both methods. Skin discoloration was followed and documented postoperatively. Data extraction and subsequent meta-analysis of all previous studies were also performed. SN detection rates were similar between standard technique succeeded and SPIO both per patient (97.1 vs. 97.6 %, p = 0.76) as well as per node (91.3 vs. 93.3 %, p = 0.34), something which was not affected by the presence of malignancy. Concordance rates were also consistently high (98.0 % per patient and 95.9 % per node). Discoloring was present in 35.5 % of patients postoperatively, almost exclusively in breast conservation. It fades slowly and is still detectable in 8.6 % of patients after 15 months. Meta-analysis depicted similar detection rates (p = 0.71) and concordance rates (p = 0.82) per patient. However, it seems that SPIO is characterized by higher nodal retrieval (p amp;lt; 0.001). SPIO is an effective method for the detection of SN in patients with breast cancer. It is comparable to the standard technique and seems to simplify logistics. Potential skin discoloration is something of consideration in patients planned for breast conservation.</p>

  • Oral health of individuals aged 3-80 years in Jonkoping, Sweden during 40 years (1973-2013)
  • 2015
  • Ingår i: Swedish Dental Journal. - Swedish Dental Journal. - 0347-9994. ; 39:2, s. 69-86
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The aim of this epidemiological study performed in 2013 was to analyze various clinical and radiographic data on oral health and compare the results to those of four cross-sectional studies carried out 1973-2003. In 1973,1983,1993,2003, and 2013 random samples of 1,000;1,104;1,078; 987; and 1,010 individuals, respectively, were studied.The individuals were evenly distributed in the age groups 3,5,10,15, 20,30,40,50, 60,70, and 8o years. Eighty-year-olds were not included in 1973. All subjects were inhabitants of the city of Jonkoping, Sweden. The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations, oral hygiene, calculus, periodontal status, and endodontic treatment. The frequency of edentulous individuals aged 40-70 years was 16,12, 8,1, and 0.3% in 1973,1983,1993, 2003, and 2013, respectively. No complete denture wearer younger than 80-years old was found in 2013. During the 40-year period, the mean number of teeth in the age groups 30-80 years increased. In 2013, the 60-year-olds had nearly complete dentitions. Implants were found in all age groups from 30 years of age.The total number of individuals with implants was 36 in 2013.This was higher than earlier surveys,4 in 1993, and 18 in 2003. The percentage of children and adults without caries and restorations increased during the 40-year period. It was found that the percentage of caries-free 3- and 5-year-olds were 79% and 69%, respectively, of the individuals in 2013. In the age groups 10-20 years, the percentage of caries-free individuals increased between 2003 and 2013. In 2013,43% of the 15-year-olds were completely free from caries and restorations compared to 20% in 2003. In all age groups 5-60 years, DFS was lower in 2013 compared to the earlier examinations.There was no major change in DFS between 2003 and 2013 in the age groups 70 and 80 years.The most obvious change was the decrease in number of FS over the 40 year period of time. Regarding crowned teeth the most clear changes between 1973 to 2013 were the decrease in percentage of crowned teeth in the age goups 4o and 50-year-olds.The percentage of endodontically treated teeth decreased between 1973 and 2013 in all age groups. In age groups-Jo-30-year-olds a major reduction from about 3o% to 15% in mean plaque score was seen between 1973-2003. Only a minor change in plaque score was seen during the last decade. For the age groups 40 years and older, a decrease in the percentage of surfaces with plaque was observed between 2003-2o13.The percentage of tooth sites with gingivitis was for zo years and older about 4o% in 1973. In 2013, the percentage was about15%.The frequency of sites with gingivitis was generally lower in 2013 compared with the other years:1973-1993. The percentage of individuals with probing pocket depths >4mm increased with age. Between 2003-2013 a clear reduction was seen in all age groups in frequency of individuals with probing pocket depth >4mm. Over the 40-year period an increase in the number of individuals with no marginal bone loss and a decrease in the number of subjects with moderate alveolar bone loss were seen. The continuous improvement in oral health and the reduced need of restorative treatment will seriously affect the provision of dental helath care and dental delivery system in the near future.</p>

    • <p>The aim of the this study was to present data on oral care habits and knowledge of oral health in 2013, and to compare these data with results from a series of four previous cross-sectional epidemiological studies. All these studies were carried out in the city ofionkoping, Sweden, in 1973,1983,1993, 2003, and 2o13.The 1973 study constituted a random sample of L000 individuals evenly distributed in the age groups 3, 5,10,15, 20, 30,40, 50, 6o, and 7o yea rs.The same age groups with addition of a group of 8o-year-olds were included in the 1983,1993, 2003, and 2013 studies, which comprised 1,104;1,078; 987; and 1,010 individuals, respectively. A questionnaire about dental care habits and knowledge of oral health was used. The questionnaire contained the same questions in all the five studies, although some had to be slightly modernised during the 40-year period. During the period 1973-2013, a continous increase of individuals in the age group 20-6o years were treated by the Public Dental Service amounting to about 5o%. Almost 7o% of the 70- and 80-year-olds were treated by private practitioners. In 2013,10-20% of the individuals in the age groups 30-40 years did not regularly visit neither Public Dental Service nor a private practitioner.The corresponding figures for the individuals 50-80 years old were 4-7%. Similar number of avoidance was reported in the previous studies. In the survey 2013, about 20-30% of the individuals in the age groups 20-50 felt frightened, sick, or ill at ease at the prospect of an appointment with the dentist.These findings were in agreement with the results from the surveys 1973-2003. Among the younger age groups, 10-15 years, a reduction in self-reported "ill at ease" was found in the surveys 2003 and 2013 compared to the previous surveys in this series. In 2013, the knowledge of the etiology of caries was known by about 6o% of the individuals which was similar to that reported 1973 zoo3.Twenty per cent of the individuals stated that they did not know which etiological factors that causes caries.This percentage was equivalent during the period 1973-2013. About 85% of the individuals in all age groups brushed their teeth with fluoride tooth paste at least two times a day.These frequencies have gradually increased during the 40-year period. Around 40% in the age groups 50-8o years used toothpicks regularly in 2013.This is a about 1/3-1/2 less compared to 2003. In the age groups 20-40 years 3-14% used toothpicks for proximal cleaning in 2013. In 2013, about 35% of the individuals never consumed soft drinks, in comparison with 20% in 2003. In the age groups 3-20 years about 20% were consuming soft drinks every day or several times a week, which is a reduction by half compared to 2013</p>

  • Identification and validation of single-sample breast cancer radiosensitivity gene expression predictors
  • 2018
  • Ingår i: Breast Cancer Research. - BioMed Central (BMC). - 1465-5411. ; 20:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Adjuvant radiotherapy is the standard of care after breast-conserving surgery for primary breast cancer, despite a majority of patients being over- or under-treated. In contrast to adjuvant endocrine therapy and chemotherapy, no diagnostic tests are in clinical use that can stratify patients for adjuvant radiotherapy. This study presents the development and validation of a targeted gene expression assay to predict the risk of ipsilateral breast tumor recurrence and response to adjuvant radiotherapy after breast-conserving surgery in primary breast cancer. Methods: Fresh-frozen primary tumors from 336 patients radically (clear margins) operated on with breast-conserving surgery with or without radiotherapy were collected. Patients were split into a discovery cohort (N = 172) and a validation cohort (N = 164). Genes predicting ipsilateral breast tumor recurrence in an Illumina HT12 v4 whole transcriptome analysis were combined with genes identified in the literature (248 genes in total) to develop a targeted radiosensitivity assay on the Nanostring nCounter platform. Single-sample predictors for ipsilateral breast tumor recurrence based on a k-top scoring pairs algorithm were trained, stratified for estrogen receptor (ER) status and radiotherapy. Two previously published profiles, the radiosensitivity signature of Speers et al., and the 10-gene signature of Eschrich et al., were also included in the targeted panel. Results: Derived single-sample predictors were prognostic for ipsilateral breast tumor recurrence in radiotherapy-treated ER+ patients (AUC 0.67, p = 0.01), ER+ patients without radiotherapy (AUC = 0.89, p = 0.02), and radiotherapy-treated ER- patients (AUC = 0.78, p < 0.001). Among ER+ patients, radiotherapy had an excellent effect on tumors classified as radiosensitive (p < 0.001), while radiotherapy had no effect on tumors classified as radioresistant (p = 0.36) and there was a high risk of ipsilateral breast tumor recurrence (55% at 10 years). Our single-sample predictors developed in ER+ tumors and the radiosensitivity signature correlated with proliferation, while single-sample predictors developed in ER- tumors correlated with immune response. The 10-gene signature negatively correlated with both proliferation and immune response. Conclusions: Our targeted single-sample predictors were prognostic for ipsilateral breast tumor recurrence and have the potential to stratify patients for adjuvant radiotherapy. The correlation of models with biology may explain the different performance in subgroups of breast cancer.
