This is a peripheral blood Collection Protocol to study the T-cell immune responses of patients with malignancies displaying one of three different patterns of antigen expression: (1) Cohort 1 focuses on cancers displaying a high (80-90%) frequency of MUC1 expression and variably high (unreported to 50%) HER2/neu (“HER2”) expression; (2) Cohort 2 focuses on primary or secondary myelofibrosis (MF) displaying mutated calreticulin (muCALR); (3) Cohort 3 focuses on glioblastoma multiforme (GBM) which often displays the cytomegalovirus tegument protein CMVpp65. Cohort 1 includes blood collections for in vitro studies which are a component of NIH-funded Project 3 within the Mayo Clinic Pancreatic SPORE, “Optimal Immunotargeting of MUC1 for Advanced Pancreatic Cancer” (Principal Investigator Dr. Gendler). Eligibility Criteria, keep current Eligibility Criteria, but precede by:: "Three cohorts of patients will be collected.:Cohort 1 includes (1) advanced unresectable pancreatic cancer, (2-4) advanced, unresectable breast cancer (up to 6 donors per phenotype: triple negative [HER2, estrogen and progesterone receptor (ER and PR) all negative], HER2 positive whatever the ER/PR status,, and HER2 negative/ER positive), (5) advanced, unresectable colorectal cancer, (6) advanced, unresectable ovarian cancer, (7) advanced, unresectable clear cell kidney cancer, (8) advanced, unresectable bladder cancer, (9) advanced, unresectable lung adenocarcinoma, (10) advanced, unresectable multiple myeloma. Also eligible are (11) up to 6 donors with triple negative breast cancer and (12) up to 6 donors with colorectal cancer who have no clinical evidence of residual (macroscopic) disease following an attempt to perform definitive treatment (including surgery, radiation and/or adjuvant or neoadjuvant chemotherapy). Cohort 2 includes (1) muCALR+ primary MF, and (2) muCALR+ secondary MF. Cohort 3 includes (1) CMVpp65 absent and (2) CMVpp65 present GBM.. Patients in all subcohorts except 1.11 and 1.12 currently have unresectable advanced or recurrent cancers, and may undergo the collection: (1) prior to initiation of systemic therapy; (2) if patient is already engaged in an ongoing cyclical systemic therapy, collection should be within three days prior to the end of the current therapy cycle, if necessary delayed until all clinical parameters are acceptable to proceed with the next planned cycle of therapy; (3) if patient is completing non-cyclical therapy, collection should be at least 2.5-3.0 weeks after completion of the therapy, or delayed until all clinical parameters are acceptable to proceed with any planned follow-up therapy. Patients in cohorts 1.11 and 1.12 (currently lacking detectable cancer) will undergo the collection at least 4 weeks after conclusion of therapy. In addition to belonging to one of these 16 subcohorts, patients will be required to have bloodwork demonstrating a blood hemoglobin ≥ 10 g/dL, a neutrophil count ≥ 1,500 /microliter, and platelets ≥ 100,000 /microliter, performed within 7 days prior to the collection.
