Direct Tumor Microinjection and FDG-PET in Testing Drug Sensitivity in Patients With Relapsed or Refractory Non-Hodgkin Lymphoma, Hodgkin Lymphoma, or Stage IV Breast Cancer

PRIMARY OBJECTIVE: I. To assess the safety of in vivo in host drug sensitivity testing in patients with breast cancer and patients with lymphoma (nodal, extranodal masses, or cutaneous lesions). SECONDARY OBJECTIVES: I. To assess the feasibility of in vivo in host drug sensitivity testing in this patient population. II. To identify targeted therapies with potential activity in relapsed lymphoma and metastatic breast cancer. III. To evaluate the adverse event profile within each patient population. CORRELATIVE OBJECTIVES: I. To assess for apoptosis in response to intratumoral injection using known biomarkers (e.g., by morphology, Ki-67, caspace-3 assay as a marker of early apoptosis). II. To evaluate intratumoral biomarkers, intratumoral cell populations, and distribution, identify potential biomarkers that correlate with response to therapy based on individual therapies. OUTLINE: Patients undergo FDG-PET and receive saline intralesionally on day 1. Patients also receive up to five additional injections of gemcitabine hydrochloride, romidepsin, belinostat, carfilzomib, copanlisib hydrochloride, nivolumab, trastuzumab, daratumumab, obinutuzumab, pembrolizumab, or rituximab intralesionally per investigator on day 1. Beginning 5 days later, patients with nodal/extranodal mass undergo restaging FDG-PET and biopsy (if clinically feasible). Within 3-7 days, patients with cutaneous disease undergo restaging photography and biopsy. After completion of study treatment, patients are followed up at 3 months.
