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

Brief description of study

This pilot phase I trial studies the side effects of direct tumor microinjection and fludeoxyglucose F-18 positron emission tomography (FDG-PET) in testing drug sensitivity in patients with non-Hodgkin lymphoma, Hodgkin lymphoma, or stage IV breast cancer that has returned after a period of improvement or does not respond to treatment. Injecting tiny amounts of anti-cancer drugs directly into tumors on the skin or in lymph nodes and diagnostic procedures, such as FDG-PET, may help to show which drugs work better in treating patients with non-Hodgkin lymphoma, Hodgkin lymphoma, or breast cancer.

Detailed Study Description


I. To assess the safety of in vivo in host drug sensitivity testing in patients with breast cancer and patients with lymphoma (nodal, extranodal or cutaneous lesions).


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.


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.


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, nivolumab, trastuzumab, daratumumab, obinutuzumab, pembrolizumab, or rituximab intralesionally per investigator on day 1. Beginning 5 days later, patients with nodal disease undergo restaging FDG-PET and biopsy (if clinically feasible). Within 3-7 days, patients with cutaneous disease undergo restaging FDG-PET, photography, and biopsy.

After completion of study treatment, patients are followed up at 3 months.
