Tidskriftsartikel (refereegranskat)abstract
- Background: Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer associated with poor survival, in which adjuvant systemic treatments are limited to chemotherapy. Due to competing mortality risks and comorbidities, older patients with TNBC are often undertreated with adjuvant chemotherapy, and clinical trials on this problem are scarce, despite a growing patient population. This study aimed to assess outcomes for patients aged 70 years and older with TNBC with or without chemotherapy in a national population-based registry, to provide information that can assist in treatment decisions for these patients. Methods: In this population-based registry study, data on all patients aged 70 years and older diagnosed with primary early TNBC (larger than 5 mm in diameter and without distant metastasis) and surgically treated between Jan 1, 2009, and Dec 31, 2016, were retrieved from the Swedish National Breast Cancer Register, the Swedish Patient Register, and the Swedish Cause of Death Register. Patients with incomplete data (on oestrogen receptor, progesterone receptor, or human epidermal growth factor receptor 2 status, surgical procedure in the breast, or information about chemotherapy) were excluded. A propensity score-matched (PSM) model was used to examine the outcomes of adjuvant chemotherapy on 5-year breast cancer-specific survival (BCSS) and 5-year overall survival (OS), adjusted for age, tumour size, tumour grade, nodal status, and comorbidities. Findings: Of 1130 women eligible for analysis, 368 (32·6%) received adjuvant chemotherapy, 45 (4·0%) received neoadjuvant treatment, and 717 (63·5%) did not receive chemotherapy. 5-year BCSS was significantly improved in patients who received adjuvant chemotherapy (85% [95% CI 81–89]) compared with patients who did not receive chemotherapy (68% [64–72]; p<0·0001). A similar benefit was observed in 5-year OS (79% [95% CI 75–84] vs 49% [45–53]; p<0·0001). In our PSM analysis, 5-year BCSS in patients treated with adjuvant chemotherapy was 83% (95% CI 78–89), versus 73% (67–80; p=0·014) in patients not treated with chemotherapy. 5-year OS in patients treated with adjuvant chemotherapy was 75% (95% CI 69–82), versus 63% (57–71; p=0·029) in patients who did not receive chemotherapy. Interpretation: In this PSM registry analysis of surgically treated female patients aged 70 years and older with TNBC without distant metastasis, we identified a significant benefit both in 5-year BCSS and 5-year OS with adjuvant chemotherapy versus no chemotherapy, which persisted when adjusting for age and comorbidities. These results underline the importance of considering adjuvant chemotherapy in older patients. Funding: Knut and Alice Wallenberg Foundation, Assar Gabrielsson Foundation.

Ingår i: Breast Cancer Research. - 1465-5411. ; 25:1

Tidskriftsartikel (refereegranskat)abstract
- BackgroundWhen ipsilateral multifocal primary breast cancer (IMBC) is detected, standard routine is to evaluate the largest tumor with immunohistochemistry (IHC). As all foci are not routinely characterized, many patients may not receive optimal adjuvant treatment. Here, we assess the clinical relevance of examining at least two foci present in patients with IMBC.MethodsPatients diagnosed and treated for IMBC at Sahlgrenska University Hospital (Gothenburg, Sweden) between 2012 and 2017 were screened. In total, 180 patients with >= 2 invasive foci (183 specimens) were assessed with IHC and included in this study. Expression of the estrogen (ER) and progesterone (PR) receptors, Ki67, HER2, and tumor grade were used to determine the molecular surrogate subtypes and discordance among the foci was recorded. An additional multidisciplinary team board was then held to re-assess whether treatment recommendations changed due to discordances in molecular surrogate subtype between the different foci.ResultsDiscordance in ER, PR, HER2, and Ki67 was found in 2.7%, 19.1%, 7.7%, and 16.9% of invasive foci, respectively. Discordance in the molecular surrogate subtypes was found in 48 of 180 (26.7%) patients, which resulted in therapy changes for 11 patients (6.1%). These patients received additional endocrine therapy (n = 2), chemotherapy (n = 3), and combined chemotherapy and trastuzumab (n = 6).ConclusionTaken together, when assessing at least two tumor foci with IHC, regardless of shared morphology or tumor grade between the different foci, 6.1% of patients with IMBC were recommended additional adjuvant treatment. A pathologic assessment using IHC of all foci is therefore recommended to assist in individualized treatment decision making.

Tidskriftsartikel (refereegranskat)abstract
- Clinical decision-making for patients with breast cancer (BC) is still primarily based on biomarker characteristics of the primary tumor, together with the evaluation of synchronous axillary lymph node metastasis (LNM). In this study, we investigated the prevalence of discordance in the biomarkers and surrogate subtyping between the primary BC and the LNM, and whether subsequent changes would have altered clinical treatment recommendations. In this retrospective study, 94 patients treated for unifocal primary BC and synchronous LNM at Sahlgrenska UniversityHospital during 2018 were included. Estrogen (ER) and progesterone (PR) receptor, Ki67, and HER2 status were assessed in the primary tumor and LNM using immunohistochemistry. Discordances between the primary tumor and the LNM were analyzed for each individual biomarker and surrogate subtyping. The concordance between the primary tumor and the LNM for ER, PR, Ki67, and HER2 status was 98.9%, 89.4%, 72.3%, and 95.8%, respectively. Discordance in surrogate subtyping was found in 28.7% of the tumors and matched LNMs, the majority (81.5%) of which changed to a more favorable subtype in the LNM; most commonly from Luminal B to Luminal A (48.6%). No changes in surrogate subtyping were detected where ER or HER2 status changed from negativity in the BC to positivity in the LNM, thereby showing no additional value in performing immunohistochemistry on the LNM from a treatment decision-making perspective. However, large studies need to be performed that test both the primary BCs and synchronous LNMs for more accurate diagnostics.

Effect of preoperative injection of superparamagnetic iron oxide particles on rates of sentinel lymph node dissection in women undergoing surgery for ductal carcinoma in situ (SentiNot study)
- 2019
-
Ingår i: British Journal of Surgery. - : Oxford University Press (OUP). - 0007-1323 .- 1365-2168. ; 106:6
-
Tidskriftsartikel (refereegranskat)abstract
- Background: One-fifth of patients with a preoperative diagnosis of ductal carcinoma in situ (DCIS) have invasive breast cancer (IBC) on definitive histology. Sentinel lymph node dissection (SLND) is performed in almost half of women having surgery for DCIS in Sweden. The aim of the present study was to try to minimize unnecessary SLND by injecting superparamagnetic iron oxide (SPIO) nanoparticles at the time of primary breast surgery, enabling SLND to be performed later, if IBC is found in the primary specimen. Methods: Women with DCIS at high risk for the presence of invasion undergoing breast conservation, and patients with DCIS undergoing mastectomy were included. The primary outcome was whether this technique could reduce SLND. Secondary outcomes were number of SLNDs avoided, detection rate and procedure-related costs. Results: This was a preplanned interim analysis of 189 procedures. IBC was found in 47 and a secondary SLND was performed in 41 women. Thus, 78.3 per cent of patients avoided SLND (P<0.001). At reoperation, SPIO plus blue dye outperformed isotope and blue dye in detection of the sentinel node (40 of 40 versus 26 of 40 women; P<0.001). Costs were reduced by a mean of 24.5 per cent in women without IBC (3990 versus 5286; P<0.001). Conclusion: Marking the sentinel node with SPIO in women having surgery for DCIS was effective at avoiding unnecessary SLND in this study. Registration number: ISRCTN18430240 (http://www.isrctn.com).

Tidskriftsartikel (refereegranskat)abstract
- Background: For women diagnosed with hormone-receptor-positive breast cancer, endocrine therapy (ET) is recommended. Patients experience diverse side effects, and difficulties in managing these side effects have been identified as obstacles for treatment continuation. The aim of this study was to describe the development of a support program for patients prescribed ET. Methods: Intervention mapping (IM) a comprehensive theory-based approach was used in the support program development. A participatory design was used and four advisory groups was formed including both patients and healthcare professionals. Results: This study employed the systematic stages of IM to develop a theory-based support program with the goal to empower patients prescribed ET to manage ETrelated symptoms and problems, and to illuminate the healthcare structure. The needs assessment identified three performance objectives: (1) Patients have knowledge of and understand their symptoms and their management strategies. (2) Patients have the knowledge and confidence to express their care needs and to ask for guidance from healthcare professionals. (3) Patients are active in and lead their healthcare process. Conclusion: This is a systematic developed model, built upon aspects of ET both from a patient´ perspective as well as from healthcare professionals’ perspectives.

- Background For patients diagnosed with hormone-receptor-positive breast cancer, endocrine therapy (ET) is prescribed, which reduces recurrence and mortality rates (Early Breast Cancer Trialists’ Collaborative Group, 2011). Despite the prognostic benefits of ET, the adherence to treatment varies, and 30%–70% of the patients discontinue their treatment within five years (Daly et al., 2017; Tinari et al., 2015; Ursem et al., 2015), often during their first year of treatment (He et al., 2015), due to the fact that ET is associated with adverse side-effects (Regan et al., 2011). Methods The study was conducted in a surgical out-patient care unit at a hospital in Sweden. Inclusion criteria were women diagnosed with breast cancer and treated with ET after surgery. Forty-eight patients were invited to participate, of which 23 declined, thus 25 women were included. Seven focus group interviews, with two to five participants in each group, were conducted using an interview guide according to Krueger’s (2014) strategy. The interview guide contained six open-ended questions aiming to explore the women’s experiences of ET after breast cancer surgery. Inductive qualitative content analysis was used (Graneheim & Lundman, 2004). Results The analysis resulted in three categories that described the women’s experiences: the treatment “creates discomfort”; “promotes levels of management”; and “causes feelings of abandonment”. Women’s experiences of treatment could at first glance be seen as positive, as perceived protection, but after further analysis, a deeper meaning was identified: protection with reservation. When experiencing discomfort, the women were urged to manage the situation, although the mode of management sometimes varied. The women reported that they needed support, but when the support did not appear, they felt as though they had been abandoned. Moreover, knowledge about side-effects became an obstacle. The participants described feeling abandoned, but they also described their disease as “cancer light”. Conclusions Professionals need to explore the pre-knowledge and preconceptions that patients might have. This could be achieved by listening to the patient before providing them with information. The information needs to be customized specifically to each person. Funding Assar Gabrielsson’s Foundation, Herbert and Karin Jacobsson’s Foundation, and the Swedish Society of Nursing.

- Objective: For patients diagnosed with hormone-receptor-positive breast cancer, endocrine therapy (ET) is usually prescribed to reduce recurrence and mortality rates. Despite the benefits, compliance with treatment varies. The aim of this study was to provide qualitative data about women's experiences with ET after breast cancer surgery. Methods: Twenty-five women, treated with Tamoxifen after breast cancer surgery, were interviewed in seven focus groups. Six open-ended questions were used to explore their experiences. The interviews were recorded, transcribed verbatim and analysed using inductive content analysis. Results: The analysis resulted in three categories that described the women's experiences: the treatment “creates discomfort”; “promotes levels of management”; and “causes feelings of abandonment”. Women's experiences of treatment could at first glance be seen as positive, as perceived protection, but after further analysis, a deeper meaning was identified: protection with reservation. When experiencing discomfort, the women tried to manage the situation, although the mode of management sometimes varied. The women reported that they needed support, but when the support did not appear, they felt as though they had been abandoned. Moreover, knowledge about side effects became an obstacle, as it could create fear of more severe symptoms. They also described that their disease was perceived by healthcare professionals as “cancer light”. Conclusion: The information needs to be customised specifically to each person. © 2019 John Wiley & Sons Ltd

Tidskriftsartikel (refereegranskat)abstract
- Objective The peRson-cEntred Support Programme EndoCrine Therapy intervention is a complex intervention encompassing a person-centred support programme for patients with breast cancer being treated with endocrine therapy (ET). The aim of this study was to explore the feasibility of the trial design and patient acceptability of the intervention and outcome measures and to provide data to estimate the parameters required to design the final intervention. Design A controlled before-and-after design following the Consolidated Standards of Reporting Trials 2010 statement for feasibility trials. Setting A surgical outpatient clinic in Sweden. Participants Forty-one patients (aged 47-85) with breast cancer who were treated with ET. Interventions Eligible patients were assigned to the control group or intervention group, which included individual education material, an individualised learning plan and a personalised reminder letter using a person-centred approach. The intervention could be delivered as a telephone or digital follow-up during a 12-week follow-up. Outcome measures The aims were to determine the recruitment rate, assess the rate of retention, explore whether the intervention was delivered according to the protocol, assess the preferred form of educational support, rate of education sessions, length per education session and length between each education session, determine the distribution of education materials and assess completion rates of patient-reported instruments, including the General Self-efficacy Scale, the Quality of Care from the Patient's Perspective Questionnaire and the Memorial Symptom Assessment Scale. Results Eighty-six per cent of the patients in the intervention group completed the intervention and questionnaires 3 months after their inclusion. The call attendance was 90%. During the intervention, the contact nurse complied with the intervention protocol. For self-efficacy, symptoms and quality of care, there were no differences in effect size between the control and intervention groups. Conclusions This intervention seems to be feasible and acceptable among patients.

- Abstract Aim: The aim was to explore stressful events, experienced problems and used coping strategies during the first three months of undergoing ET. Design: This study used a mixed method design. Methods: A consecutive sample of 39 women newly diagnosed with breast cancer were included at the start of their adjuvant endocrine therapy. A daily coping assessment was used to create daily reports about stressful events or experienced problems and coping strategies. Results: The most frequently reported physical problems were sleeping difficulties. Anxiety was the most reported emotional problem. Patients used both emotion-and problem-focused coping, and sleeping difficulties were coped by relaxing, and anxiety was coped by thinking about something else. Conclusions: Patients experienced a variety of stressful events or problems during the first three months of endocrine therapy. They also used several coping strategies to endure the treatment.

- Isolated limb perfusion (ILP) is a treatment option for unresectable in-transit melanoma metastases of the extremities. Approximately two-thirds of the patients have a complete response, and known predictive factors mainly regard tumor burden. In an attempt to identify subgroups with higher response rates, we retrospectively analyzed the predictive value of the BRAF V600E/K mutation for response at our institution.Between January 2012 and December 2017, 98 consecutive patients underwent first-time ILP with melphalan for melanoma in-transit metastases and were included in the study. Data was retrieved from our prospectively kept database. Tumor burden was assessed preoperatively as number of lesions and largest tumor diameter. BRAF status was determined according to clinical routine. Response rates were classified according to WHO criteria.Of the 98 patients included in the analysis, 32 patients had a BRAF V600E/K mutation (33%) and 66 patients were BRAF wild type (wt). There was no difference in age, sex or tumor burden between the groups. Comparing response between BRAF V600E/K mutation and BRAF wt, the overall response rate was 69% vs. 77% (p=.36) and the complete response rate was 47% vs. 52% (p=.67). There was no difference in survival, with a median survival of 47 months.In this consecutive series of patients, BRAF V600E/K mutation was not found to be a significant factor for response or survival following ILP.
