cellular adoptive immunotherapy in treating a patient who has undergone a donor stem cell transplant for breast cancer that has spread to the lung

Conditions: Breast Cancer; Metastatic Cancer

Summary: rationale: biological therapy, such as cellular adoptive immunotherapy, may stimulate the immune system in different ways and stop tumor cells from growing. purpose: this phase i trial is studying how well cellular adoptive immunotherapy works in treating a patient who has undergone a donor stem cell transplant for breast cancer that has spread to the lung.

objectives: primary * determine the antitumor response in a patient with persistent metastatic breast cancer after prior allogeneic hematopoietic stem cell transplantation (sct) treated with tumor-derived, ex vivo expanded and costimulated t-lymphocytes. secondary * evaluate the immune function of tumor-derived t-lymphocytes and the biology of residual tumor cells present after allogeneic hematopoietic sct. outline: this is a pilot study. the patient undergoes surgical resection of the accessible lesions from which t cells are isolated, costimulated, and expanded ex vivo to produce the tumor-derived t-lymphocytes (tdtl). beginning at least 2 weeks after surgery, the patient receives tdtl iv every 4 weeks for up to 5 doses in the presence of disease progression (dp) and in the absence of ≥ grade 2 graft-versus-host disease. the patient is assessed 4 weeks after every dose. in case of stable disease, partial response, or complete response, the patient is followed without intervention until dp. in case of dp after dose 1 or 2 of the tdtl, the patient receives dose 2 or 3 of the tdtl. in case of dp after dose 3 of the tdtl, the patient receives low-dose interleukin-2 subcutaneously (sc) daily for 3 days and dose 4 of the tdtl. in case of dp after dose 4 of the tdtl, the patient receives 1 course of chemoimmunotherapy for cytoreduction and immunomodulation comprising paclitaxel iv over 3 hours once and trastuzumab (herceptin®) iv over 30-90 minutes once weekly for 3 weeks (the patient may receive gemcitabine hydrochloride, vinorelbine ditartrate, docetaxel, or capecitabine in combination with trastuzumab \[herceptin®\] as chemoimmunotherapy at the discretion of the principal investigator); interleukin-2 sc daily for 3 days; and dose 5 of the tdtl. in case of dp after dose 5 of the tdtl, the patient may receive cytotoxic chemotherapy and/or fda-approved biologic therapy and/or immunotherapy with donor lymphocyte infusions from the same donor used for the prior allogeneic stem cell transplantation. the patient may undergo core biopsy of the left mediastinal nodule in case of tumor regression of the indexing lesion at anytime or after receiving dose 5 of the tdtl. after completion of study treatment, the patient is followed periodically for 5 years. projected accrual: one patient will be accrued for this study.

Eligibility criteria:
