      Evans, D Gareth R; Birch, Jillian M; Orton, Clive I; CRC Department of Cancer Genetics, Paterson Institute for Cancer Research, Manchester, UK. (1991)
      We describe the occurrence of a medulloblastoma and an astrocytoma in successive generations of a family with the Gorlin syndrome. The appearance of thousands of invasive basal cell carcinomata after craniospinal irradiation led to the death of one patient from intracranial involvement.

      Pathological mutations in BRCA1, BRCA2 and TP53 are associated with an increased risk of breast cancer. This study evaluated mutation frequency of these genes in early-onset breast cancer patients, and correlated this with family history and determined relative risks to family members. Patients with breast adenocarcinoma diagnosed 30 years were ascertained between 1980 and 1997. Family history was established and mutation screening of BRCA1, BRCA2 and TP53 genes was performed. Estimates of penetrance and relative risk were undertaken. DNA was obtained from 100/139 women. 17/36 familial cases had a BRCA1, BRCA2 or TP53 mutation. Of 64 non-familial cases, one BRCA2, two BRCA1 and two TP53 mutations were detected. Penetrance estimates (by age 70) for breast cancer were 84% for BRCA1 mutations and 91% for BRCA2 mutations and for ovarian cancer, 60% and 26%, respectively. Relative risks associated with mutations were consistent with previous studies. BRCA1 and BRCA2 mutations in patients with breast cancer 30 years are predicted strongly by family history. The majority of families with ovarian cancer were due to mutations in BRCA1/2 whereas these mutations only accounted for 30-50% of the excess breast cancers.

    • Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK 'Alert Level 4' phase of the B-MaP-C study

      Dave, R. V.; Kim, B.; Courtney, A.; O'Connell, R.; Rattay, T.; Taxiarchi, V. P.; Kirkham, J. J.; Camacho, E. M.; Fairbrother, P.; Sharma, N.; et al. (2021)
      Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated 'standard' or 'COVID-altered', in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had 'COVID-altered' management. 'Bridging' endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2-9%) using 'NHS Predict'. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of 'COVID-altered' management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown.
    • Breast cancer stem cells and their role in resistance to endocrine therapy.

      O'Brien, Ciara S; Farnie, Gillian; Howell, Sacha J; Clarke, Robert B; School of Cancer and Imaging Sciences, Paterson Institute for Cancer Research, University of Manchester, Manchester, M20 4BX, UK. (2011-04)
      Developmentally, tumours can be viewed as aberrant versions of normal tissues. For example, tumours often retain differentiation markers of their tissue of origin. In addition, there is evidence that they contain cancer stem-like cells (CSCs) that drive tumourigenesis. In this review, we summarise current evidence that breast CSCs may partially explain endocrine resistance in breast cancer. In normal breast, the stem cells are known to possess a basal phenotype and to be mainly oestrogen receptor-α-negative (ER-). If the hierarchy in breast cancer reflects this, the breast CSC may be endocrine resistant because it expresses very little ER and can only respond to treatment by virtue of paracrine signalling from neighbouring, differentiated ER+ tumour cells. Normal breast epithelial stem cells are regulated by the epidermal growth factor receptor and other growth factor receptor signals. The observed increase in growth factor receptor expression in endocrine-resistant breast cancers may reflect a bigger proportion of CSCs selected by endocrine therapies. There is evidence from a number of studies that breast CSCs are ER- and EGR+/HER2+, which would support this view. It is reported that CSCs express mesenchymal genes, which are suppressed by ER expression, further indicating the mutual exclusion between ER+ cells and the CSCs. As we learn more about CSCs, differentiation and the expression and functional activity of the ER in these cells in diverse breast tumour sub-types, it is hoped that our understanding will lead to new modalities to overcome the problem of endocrine resistance in the clinic.
    • Breast cancer stem cells: something out of notching?

      We and others have established that the developmental Notch receptor signaling pathway is active in breast cancer cell lines, as well as in preinvasive and invasive primary samples. Recently, a role for Notch in regulating the hierarchy of stem and progenitor cells in both normal and cancer epithelium has been elucidated. Because inhibiting the Notch receptor signaling pathway is a possible future breast cancer therapy, here, we review the expression and activity of the different ligands and receptors and summarize the various ways in which the pathway's activity can be inhibited, and the likely effects of inhibition on different tumor cell subpopulations.
    • Breast cancer stromal clotting activation (Tissue Factor and thrombin): A pre-invasive phenomena that is prognostic in invasion

      BACKGROUND: Tumor stroma, of which fibroblasts are the most abundant cell, resembles a non-healing wound, where a procoagulant environment creates a permissive milieu for cancer growth. We aimed to determine if tumor expression of coagulation factors (procoagulant phenotype), and systemic hypercoagulability, occur at the preinvasive (ductal carcinoma in situ; DCIS) stage and correlate with breast cancer subtype, disease-free survival (DFS), and overall survival (OS). METHODS: In a prospective cohort of early breast cancer (DCIS, n = 76; invasive, n = 248) tumor, normal breast and plasma were examined. Fibroblast and epithelial expression of Tissue Factor (TF), thrombin, PAR1, PAR2, and plasma thrombin-antithrombin (TAT) and D-dimer were correlated with clinicopathological data, and 5-year survival. RESULTS: Fibroblast expression of TF, thrombin, and PAR1 was increased in DCIS and invasive cancer compared to normal breast fibroblasts (P ? .003, all). Fibroblast TF, thrombin, PAR1, and PAR2 was increased in cancers with high Ki67, high grade, ER- (vs ER+), and HER2+ (vs HER2-) (all P < .05). On univariate analysis, fibroblast TF expression was inversely associated with DFS (P = .04) and OS (P = .02). D-dimer was higher in node positive (507 (CI: 411-625) ng/mL, n = 68) vs negative patients (428 (CI: 387-472) ng/mL, n = 171, P = .004) and inversely associated with OS (P = .047). On multivariate analysis, plasma TAT was associated with reduced OS (HR 3.26, CI 1.16-3.1, P = .02), with a high plasma TAT (?3.2 ng/mL) associated with > 3-fold mortality risk compared to low TAT. CONCLUSION: This demonstrates procoagulant phenotypic changes occur in fibroblasts at the preinvasive stage. Fibroblast procoagulant phenotype is associated with aggressive breast cancer subtypes and reduced survival. Coagulation may be a therapeutic target in breast cancer.

      Recent results have increased our understanding of normal stem cells and the signalling pathways which regulate them during the development of the mammary gland. Tumours in many tissues are now thought to develop from dysregulated stem cells and depend on activated stem cell self-renewal pathways such as Notch for their tumourigenic capacity. These cancer stem cells are recognised by specific cell surface proteins that they express and their capacity to grow tumours in vivo or spheres in vitro. We have described human breast DCIS mammospheres grown from cancer stem cells and demonstrated their dependence on the EGF and Notch receptor pathways. Stem cell self-renewal pathways such as these may represent novel therapeutic targets to prevent recurrence of pre-invasive and invasive breast cancer.

    • Brentuximab Vedotin (SGN-35) in Patients With Relapsed or Refractory Systemic Anaplastic Large-Cell Lymphoma: Results of a Phase II Study.

      Pro, B; Advani, R; Brice, P; Bartlett, N; Rosenblatt, J; Illidge, Timothy M; Matous, J; Ramchandren, R; Fanale, M; Connors, J; et al. (2012-06-20)
      PURPOSE Systemic anaplastic large-cell lymphoma (ALCL) is an aggressive subtype of T-cell lymphoma characterized by the uniform expression of CD30. The antibody-drug conjugate brentuximab vedotin delivers the potent antimicrotubule agent monomethylauristatin E to CD30-positive malignant cells. A phase II multicenter trial was conducted to evaluate the efficacy and safety of brentuximab vedotin in patients with relapsed or refractory systemic ALCL. PATIENTS AND METHODS Patients with systemic ALCL and recurrent disease after at least one prior therapy received brentuximab vedotin 1.8 mg/kg intravenously every 3 weeks over 30 minutes as an outpatient infusion. The primary end point of the study was overall objective response rate as assessed by independent central review. Results Of 58 patients treated in the study, 50 patients (86%) achieved an objective response, 33 patients (57%) achieved a complete remission (CR), and 17 patients (29%) achieved a partial remission. The median durations of overall response and CR were 12.6 and 13.2 months, respectively. Grade 3 or 4 adverse events in ≥ 10% of patients were neutropenia (21%), thrombocytopenia (14%), and peripheral sensory neuropathy (12%). CONCLUSION Brentuximab vedotin induced objective responses in the majority of patients and CRs in more than half of patients with recurrent systemic ALCL. Targeted therapy with this CD30-directed antibody-drug conjugate may be an effective treatment for relapsed or refractory systemic ALCL and warrants further studies in front-line therapy.

    • Brr6 drives the Schizosaccharomyces pombe spindle pole body nuclear envelope insertion/extrusion cycle.

      Tamm, T; Grallert, Agnes; Grossman, Emily P S; Alvarez-Tabares, Isabel; Stevens, Frances E; Hagan, Iain M; Cancer Research UK Cell Division Group, Paterson Institute for Cancer Research, Manchester M20 4BX, England, UK. (2011-10-31)
      The fission yeast interphase spindle pole body (SPB) is a bipartite structure in which a bulky cytoplasmic domain is separated from a nuclear component by the nuclear envelope. During mitosis, the SPB is incorporated into a fenestra that forms within the envelope during mitotic commitment. Closure of this fenestra during anaphase B/mitotic exit returns the cytoplasmic component to the cytoplasmic face of an intact interphase nuclear envelope. Here we show that Brr6 is transiently recruited to SPBs at both SPB insertion and extrusion. Brr6 is required for both SPB insertion and nuclear envelope integrity during anaphase B/mitotic exit. Genetic interactions with apq12 and defective sterol assimilation suggest that Brr6 may alter envelope composition at SPBs to promote SPB insertion and extrusion. The restriction of the Brr6 domain to eukaryotes that use a polar fenestra in an otherwise closed mitosis suggests a conserved role in fenestration to enable a single microtubule organizing center to nucleate both cytoplasmic and nuclear microtubules on opposing sides of the nuclear envelope.
    • Bryostatin 1 induces productive Epstein-Barr virus replication in latently infected cells: implications for use in immunocompromised patients.

      Stewart, James P; McGown, Alan T; Prendiville, Joseph A; Pettit, G R; Fox, Brian W; Arrand, John R; CRC Department of Molecular Biology, Paterson Institute for Cancer Research, Christie CRC Cancer Centre, Manchester, UK. (1993)
      Bryostatin 1 is a novel anti-tumor agent currently undergoing clinical trial. We investigated the effect of this drug on B-lymphocyte cell lines that carry the Epstein-Barr virus and found that it induces these latently infected cells into the production of transforming virus particles over a wide range of concentrations. These results may have clinical implications, particularly with regard to the use of the drug in the immunocompromised patient.
    • Bryostatin 1-tamoxifen combinations show synergistic effects on the inhibition of growth of P388 cells in vitro.

      McGown, Alan T; Jayson, Gordon C; Pettit, G R; Haran, M S; Ward, Timothy H; Crowther, Derek; Paterson Institute for Cancer Research, Christie Hospital NHS Trust, Manchester, UK. (1998)
      This study shows that combinations of bryostatin 1, a novel modulator of protein kinase C currently under clinical evaluation, with the anti-oestrogenic agent tamoxifen caused a large synergistic enhancement of growth inhibition in P388 cells in vitro. The growth-inhibitory effects of bryostatin 1 in the presence of non-inhibitory concentrations of tamoxifen were increased by approximately 200-fold, whereas growth inhibition by tamoxifen in the presence of non-inhibitory concentrations of bryostatin 1 were increased over 30-fold. These data have been confirmed by isobologram analysis. The precise mechanism underlying this effect is unknown, although preliminary data implicating protein kinase C is presented. The magnitude of this synergistic effect, together with evidence of clinical responses seen when these agents were given sequentially in ovarian cancer, merits further study.

    • Building better chimeric antigen receptors for adoptive T cell therapy.

      The last few years have seen the transfer of two decades of research into Chimeric Antigen Receptors (CARs) into clinical trials. Despite this extensive research, there is still a great deal of debate into the optimal design strategy for these, primarily, anti-cancer entities. The archetypal CAR consists of a single-chain antibody fragment, specific to a tumour-associated antigen, fused to a component of the T-cell receptor complex (typically CD3zeta) which on antigen binding primes the engrafted T-cell for anti-tumour activity. The modular nature of these artificial receptors has enabled researchers to modify aspects of their structure, including the extracellular spacer, transmembrane and cytoplasmic domain, to achieve laboratory defined optimal activity. Despite this there is no consensus on the optimal structure, a problem exacerbated by conflicting results using identical receptors. In this review, we provide a structural overview of CAR development and highlight areas that require further refinement. We also attempt to identify possible reasons for conflicting results in the hope that this information will inspire future rational design strategies for optimal tumour targeting using CARs.
