  • Research area: Breast Cancer
  • Description: Please register your interest through the enquiry button (quote not currently available) Human breast cancer-derived xenograft that retains high fidelity to original tumour and provides valuable resources for drug discovery and precision oncology. This panel of Patient Derived Xenografts provide models for some of the deadliest forms of breast cancer including drug-resistant, metastatic tumours, and endocrine-resistant estrogen receptor-positive (ER+) and HER2+ tumours. Sample collected from lung met of Caucasian female, age 60 at time of collection with a primary diagnosis of DCIS; 2005, breast recurrence 2015, lung mets 2017. Patient had no former history of smoking and had clinical metastasis in lung and chest wall detected. Patient had undergone radiation therapy of breast 2005-2006 and had received systemic treatment of tamoxifen 2006; dose dense doxorubicin, cyclophosphamide 2015- 2016; taxol low dose 2016; carboplatin 2016; capecitabine 2016 prior to sample collection. Patient and PDX characteristics were as follows - ER status: negative, PR status: negative, HER2 status: negative. PDX information: PAM50 subtype not done and metastasis tests not done.

Patient Details

  • Cancer type: Breast Cancer
  • Cancer subtype: Ductal Darcinoma in Situ, Lung metastasis
  • Biopsy site: Lung metastasis
  • Gender: Female
  • Patient ethnicity: Caucasian
  • Treatment history: Pretreated: Patient had undergone radiation therapy of breast 2005-2006 and had received systemic treatment of tamoxifen 2006; dose dense doxorubicin, cyclophosphamide 2015- 2016; taxol low dose 2016; carboplatin 2016; capecitabine 2016 prior to sample collection

Engraftment Details

  • Mice passaged: Yes
  • Engraftment site: Cleared mammary fat pad
  • Host strain: Immunocompromised mice NOD scid gamma (NSG) Jackson Laboratory 5557; NOD/scid, Jackson Laboratory 1303 or NOD rag gamma (NRG), Jackson Laboratory 7799
  • Production details: Fresh or thawed human breast tumour fragments were implanted into the cleared inguinal mammary fat pad of female Immune-compromised mice. For bone metastasis samples, bone fragments were coimplanted. For liquid specimens, pleural effusion, or ascites fluid, 1-2 milion cells were injected into cleared mammary fat pads in Matrigel. For ER+ tumours, mice were dosed with E2 beeswax pellets and given supplemental E2 via drinking water. When tumours reached 1-2 cm in diameter, tumours were aseptically collected and reimplanted into new m ice or banked. Estrogen-independent ER+ breast PDX models were generated when ER+ PDX tumours were transplated into overiectomized mice without E2 supplementation.

Handling

  • Initial handling information: Implant into the cleared inguinal mammary fat pad of female Immune-compromised mice NSG and NRG. Both NSG (fresh) and NRG (fresh) time to growth: 4 months to 2 cm
