  • Inflammatory cells in node-negative breast cancer
  • 2012
  • Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 51:5, s. 680-686

    • Background.To study the impact of inflammatory cells in a clinically well-defined cohort of women with node-negative breast cancer in a nested case-control study design.Material and methods.The cohort was comprised of 190 women who died from breast cancer and 190 women still alive at the date of death for the corresponding breast cancer patients were used as controls. The inclusion criteria included; a tumour size ≤ 50 mm, no lymph node metastases and no initiation of adjuvant chemotherapy. Immunohistochemical stainings for CD3, CD4, CD8, FoxP3, CD20, tryptase and CD68 were performed on TMA blocks, evaluated and correlated to each other and to age, tumour size, histological grade, ER, PgR, Ki67 and cyclin A.Results.There was no difference regarding the amount or content of inflammatory cells in the cases compared to controls. T- and B-cells were highly correlated to each other but these cell types correlated to a lesser extent to macrophages and not at all to mast cells. A weak tendency of correlations between all the subsets of inflammatory cells and histological grade, Ki67 and cyclin A was observed, although a negative correlation was seen for mast cells.Conclusion.The amount or content of inflammatory cells in invasive breast cancer did not appear to influence death in node-negative breast cancer.

    • A large proportion of women with lymph node negative breast cancer treated with chemotherapy do not benefit from such treatment. Proliferation markers have been shown to recognize patients at high risk for recurrence. Ki67 has recently been included in the St Gallen guidelines. We investigated the prognostic importance of cyclin B1 in node negative breast cancer and included a study of reproducibility. In a population-based case-control study 190 women who died from breast cancer were defined as cases and 190 women alive at the time for the corresponding case's death as controls. Inclusion criteria were tumor size < 50 mm, no lymph node metastases, and no adjuvant chemotherapy. Tumor tissue was immunostained for cyclin B1. Two investigators evaluated the staining independently by counting approximately 100, 200, 500, and 1000 cells. Cyclin B1 was statistically significantly associated to breast cancer death, in both uni- and multivariate analyses (adjusted for tumor size, age, and endocrine therapy), with odds ratios 2-3 for both investigators. The agreement between the two investigators was good to very good, regardless of the number of counted cells (kappa values between 0.74 and 0.82).Cyclin B1 is a prognostic factor for breast cancer death in a population-based node negative patient cohort which can identify high-risk patients with a good to very good reproducibility.

  • Breast cancer with neoductgenesis : histopathological criteria and its correlation with mammographic and tumour features
  • 2014
  • Ingår i: International Journal of Breast Cancer. - 2090-3170 .- 2090-3189. ; 2014
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction. Breast cancer with mammographic casting type calcifications, high grade DCIS with an abnormal number of ducts, periductal desmoplastic reaction, lymphocyte infiltration, and tenascin-C (TN-C) overexpression has been proposed to represent a more aggressive form of breast cancer and has been denominated as breast cancer with neoductgenesis. We developed histopathological criteria for neoductgenesis in order to study reproducibility and correlation with other tumour markers.Methods. 74 cases of grades 2 and 3 DCIS, with or without an invasive component, were selected. A combined score of the degree(s) of concentration of ducts, lymphocyte infiltration, and periductal fibrosis was used to classify cases as showing neoductgenesis, or not. Diagnostic reproducibility, correlation with tumour markers, and mammographic features were studied.Results. Twenty-three of 74 cases were diagnosed with neoductgenesis. The kappa value between pathologists showed moderate reproducibility (0.50) (95% CI; 0.41-0.60). Neoductgenesis correlated significantly with malignant type microcalcifications and TN-C expression (P = 0.008 and 0.04) and with ER, PR, and HER2 status (P &lt; 0.00001 for all three markers).Conclusions. We developed histological criteria for breast cancer with neoductgenesis. Neoductgenesis, by our applied histopathological definition was related to more aggressive tumour biology and malignant mammographic calcifications.

  • Annan publikation (övrigt vetenskapligt)abstract
    • Background: A new subgroup of breast cancer has been proposed: breast carcinoma with neoductgenesis. Cases presenting with casting type calcifications on the mammogram, histologically high grade DCIS with an abnormal number of ducts, periductal desmoplastic reaction and lymphocyte infiltration has been suggested to represent a more aggressive form of breast cancer. Treatment decision based on traditional histopathology showing DCIS might be challenged if neoductgenesis is diagnosed. We evaluated a histological classification system proposed for neoductgenesis and studied tumor biology in cases with and without neoductgenesis. Material and Method: Seventy-four tumors with DCIS grade 2-3, with or without an invasive component, were blocked in TMAs. A classification system based on a pathological evaluation and Tenascin-C (Tn-C) expression was used to categorize tumors as showing neoductgenesis or not. Immunohistochemical staining for known tumor markers and correlation with mammographic features was performed. Logistic regression model was use to evaluate the correlation between breast carcinoma with neoductgenesis and molecular- and mammographic features. Results: Four pathologists could categorize cases as “possible neoductgenesis” with an overall correlation of 72% and a kappa value of 0.44. Adding Tn-C staining resulted in a group with neoductgenesis (n=37) and one without (n=31). Neoductgenesis correlated significantly with mammographic casting- and crushed stone microcalcifications and estrogen receptor status (p-values 0.04 and 0.03, respectively). High nuclear grade, HER2 positivity, progesterone receptor negativity and high proliferation were also more often seen in the group with neoductgenesis, but this was not statistically significant (0.10, 0.07, 0.20 and 0.29). Discussion: We developed reproducible histologic criteria for a new entity: breast carcinoma with neoductgenesis. The system seemed to be useful in receiving reproducibility between pathologists making the diagnosis. Neoductgenesis was related to more aggressive tumor biology and to the mammographic features. Our findings have to be repeated and the relation to prognosis further studied. However, we can already predict a potential benefit for women earlier considered having a pure DCIS but now diagnosed as breast carcinoma with neoductgenesis and a need to develop appropriate treatment regiments.

  • Tumor Markers Predicting Type of Recurrence after a Primary Ductal Carcinoma In Situ
  • 2012
  • Ingår i: Breast Cancer Research. - 1465-5411 .- 1465-542X.
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Introduction: About half of all recurrences after a primary ductal carcinoma in situ (DCIS) are invasive. The determinants for type of recurrence, in situ or invasive, are not known. We studied markers in primary DCIS in relation to type of recurrence.Methods:Two hundred and sixty six primary DCIS with a known recurrence were included. One hundred were from a population based cohort with 458 women diagnosed 1986-2004 in Uppland/Västmanland region, Sweden, and all 166 women with a recurrence from the randomized nationwide SweDCIS Trial (1987-1999). The 358 women without a recurrence were used as a reference group. TMA-blocks were constructed and estrogen receptor- (ER), progesterone receptor- (PR), HER2, EGFR, cytokeratin 5/6, Ki67, FOXA1, FOXC1, GATA-3 and CD10 status were evaluated in the primary tumors. Logistic regression was used to calculate odd ratios and 95% confidence intervals in univariate and multivariate analyses (adjusted for age, free margin, surgical method and molecular subtype).Results:One hundred and thirty of the recurrences were in situ and 136 invasive. In multivariate analyses, a recurrence was more often invasive if the primary was ER positive (OR 2.5, CI 95 1.2 – 5.1). Primaries being HER2 positive (OR 0.5, CI 95 0.3-0.9), EGFR positive (OR 0.4, CI 95 0.2-0.9) and ER-/HER2+ (OR 0.2, CI 95 0.1-0.6) had a lower risk of the recurrence being invasive. Primaries of the molecular subtype ER+/HER2+ had higher risk of any recurrence (OR 1.9, CI 95 1.1-3.4) as did primaries expressing FOXA1 (OR 3.1, CI 95 1.5-6.2) and FOXC1 (OR 2.9, CI 95 1.7-5.0).Conclusions:Surprisingly, recurrences after an ER-/HER2+, ER negative or EGFR positive primary DCIS were more often of the in situ type. The molecular subtype ER+/HER2+, FOXA1 positivity and FOXC1 positivity were risk factors for any recurrence.

  • Aberrant expression of cyclin E in low-risk node negative breast cancer
  • 2008
  • Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 47:8, s. 1539-1545
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. Cyclin E is a cell cycle regulatory protein which occurs in G1, peaks in late G1 and is degraded in early S-phase. Cyclin E overexpression appears to be an independent prognostic factor for overall survival in breast cancer. Material and Methods. Nuclear cyclin A is a reliable marker for S-and G2-phases. Consequently, aberrant expression of cyclin E can be detected by simultaneous immunostainings for cyclin A and cyclin E. Studies have shown that aberrant cyclin E might provide additional prognostic information compared to that of cyclin E alone. This study aimed to investigate cyclin E and aberrant cyclin E expression in low-risk node negative breast cancer. We compared women that died from their breast cancer (n=17) with women free from relapse&gt;8 years after initial diagnosis (n=24). All women had stage I, low risk breast cancer. The groups were matched regarding tumour size, receptor status, adjuvant chemotherapy and tumour differentiation. Tumour samples were analysed regarding expression of cyclin A, cyclin E and double-stained tumour cells using immunoflourescence staining and digital microscopy. Results. No differences were seen regarding expression of cyclin E or aberrant cyclin E in cases compared to controls. Discussion. We conclude that neither cyclin E nor aberrant cyclin E is a prognostic factor in low-risk node negative breast cancer patients.

  • Colored body images reveal the perceived intensity anddistribution of pain in women with breast cancer treated with adjuvant taxanes: : a prospective multi-method study of pain experience
  • 2018
  • Ingår i: Scandinavian Journal of Pain. - Berlin/Boston. - 1877-8860 .- 1877-8879. ; s. 581-591
  • Forskningsöversikt (övrigt vetenskapligt)abstract
    • Background and aims:Breast cancer is the most prevalent adult cancer worldwide. A broader use of screening for early detection and adjuvant systemic therapy with chemotherapy has resulted in improved survival rates. Taxane-containing chemotherapy is one of the cornerstones of the treatment. However, taxane-containing chemotherapy may result in acute chemotherapy-induced nociceptive and neuropathic pain. Since this pain may be an additional burden for the patient both during and after taxane chemotherapy, it is important to rapidly discover and treat it. There is yet no gold standard for assessing taxane-induced pain. In the clinic, applying multiple methods for collecting information on pain may better describe the patients’ pain experiences. The aim was to document the pain during and after taxane through the contribution of different methods for collecting information on taxane-induced pain. Fifty-three women scheduled for adjuvant sequential chemotherapy at doses of ≥75 mg/m2 of docetaxel and epirubicin were enrolled in the study.Methods:Prospective pain assessments were done on a visual analog scale (VAS) before and during each cycle of treatment for about 5 months, and using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire’s (EORTC-QLQ-C30) two pain questions at baseline, 3 months, and 12 months. Participants scoring pain on the VAS &gt;30 and undergoing an interview also colored their pain on a body image during treatment and at 12 months.Results:Surprisingly widespread, intense pain was detected using a multi-method approach. The colored body image showed pain being perceived on 51% of the body surface area during treatment, and on 18% 12 months after inclusion. In general, the pain started and peaked in intensity after the first cycle of taxane. After Cycle 3, most women reported an increase in pain on the VAS. Some women continued to report some pain even during the epirubicin cycles. The VAS scores dropped after the last chemotherapy cycle, but not to the baseline level. At baseline, 3 months and 12 months after inclusion, the women who estimated VAS &gt;30 reported higher levels of pain on the pain questions of the EORTC-QLQ-C30.Conclusions:This study contributes information on how different pain assessment tools offer different information in the assessment of pain. The colored body image brings another dimension to pain diagnostics, providing additional information on the involved body areas and the pain intensities as experienced by the women. A multi-method approach to assessing pain offers many advantages. The timing of the assessment is important to properly assess pain.Implications:Pain relief needs to be included in the chemotherapy treatment, with individual assessment and treatment of pain, in the same way as is done in chemotherapy-triggered nausea. There is a time window whereby the risk of pain development is at its highest within 24–48 h after receiving taxane chemotherapy. Proper attention to pain evaluation and treatment should be in focus during this time window.

    • Male breast cancer is poorly understood with a large proportion arising in the familial context particularly with the BRCA2 germline mutation. As phenotypic and genotypic differences between sporadic and familial male breast cancers have been noted, we investigated the importance of a hypoxic drive in these cancers as this pathway has been shown to be of importance in familial female breast cancer. Expression of two major hypoxia-induced proteins, the hypoxia-inducible factor-1α (HIF1A) and the carbonic anhydrase IX (CA9), examined within a large cohort including 61 familial (3 BRCA1, 28 BRCA2, 30 BRCAX) and 225 sporadic male breast cancers showed that 31% of all male breast cancers expressed either HIF1A (25%) and/or CA9 (8%) in the combined cohort. Expression of HIF1A correlated with an increased incidence of a second-major malignancy (P=0.04), histological tumor type (P=0.005) and basal phenotype (P=0.02). Expression of CA9 correlated with age (P=0.004) in sporadic cases and an increased tumor size (P=0.003). Expression of HIF1A was prognostic for disease-specific survival in sporadic male breast cancers (HR: 3.8, 95% CI: 1.5-9.8, P=0.006) but not within familial male breast cancer, whereas CA9 was only prognostic in familial male breast cancers (HR: 358.0, 95% CI: 9.3-13781.7, P=0.002) and not in sporadic male breast cancer. This study found that hypoxic drive is less prevalent in male breast cancer compared with female breast cancer, possibly due to a different breast microenvironment. The prognostic impact of HIF1A is greatest in sporadic male breast cancers with an alternate dominant mechanism for the oncogenic drivers suggested in high risk familial male breast cancers.Modern Pathology advance online publication, 24 January 2014; doi:10.1038/modpathol.2013.231.
