Eligibility Criteria:
Inclusion Criteria:~* Synovial sarcoma that has been treated with standard chemotherapy containing ifosfamide and/or doxorubicin and remains: unresectable or metastatic or progressive/persistent or recurrent disease~* Measurable disease~* Patients must have proven positive tumor sample for NY-ESO-1 as follows:~  * Cohort 1 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.~ * Cohort 2 -Positive expression is defined as ≥1+ by immunohistochemistry in ≥1% cells, but not to exceed 2+ and/or 3+ in ≥ 50% of cells.~ * Cohort 3 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.~ * Cohort 4 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.~* HLA-A\*02:01, HLA-A\*02:05, and/or HLA-A\*02:06 by high resolution testing at a local or central laboratory~* Weigh more than 18 kg~* All previous cytotoxic chemotherapy, monoclonal antibody therapy, or immune therapy must be washed out 3 weeks before apheresis and must be completed at least 3 weeks prior to pre-infusion lymphodepletive chemotherapy.~* Systemic corticosteroid or other immunosuppressive therapy should be washed out 2 weeks before apheresis and must be completed at least 2 weeks prior to pre-infusion lymphodepletive chemotherapy.~* Biologic or other approved molecular targeted small molecule inhibitors should be washed out 1 week or 5 half-lives (whichever is longer) before apheresis and must be completed at least 1 week or 5 half-lives (whichever is longer) prior to pre-infusion lymphodepletive chemotherapy.~* Any grade 3 or 4 hematologic toxicity of any previous therapy must have resolved to grade 2 or less prior to apheresis and any grade 3 or 4 toxicity must have resolved to grade 2 or less prior to pre-infusion lymphodepletive chemotherapy.~* ECOG 0-1, or for children ≤10 years of age, Lansky \> 60~* Life expectancy \> 3 months~* Left ventricular ejection fraction ≥ 40% or fractional shortening ≥ 28%~* T. bilirubin \< 2 mg/dl (Patients with Gilbert Syndrome total bilirubin \<3xULN and direct bilirubin ≤ 35%)~* AST, ALT ≤ 2.5 x upper limit of normal~* ANC ≥ 1.0 x 10⁹/L~* Platelets ≥ 75 x 10⁹/L~* Age-adjusted normal serum creatinine or a creatinine clearance ≥ 40 ml/min~* Ability to give informed consent for patients greater than 18 years of age. For patients less than 18 years of age the legal guardian must give informed consent.~* Male patients must be willing to practice birth control (including abstinence) during and for 4 months after treatment. Female patients must be willing to practice birth control (including abstinence) during treatment and for 4 months after gene modified cells are no longer detected in body.~Exclusion Criteria:~* Active HIV, HBV, HCV or HTLV 1/2 infection (due to increased risk of complications during lymphodepleting regimen and confounding effects on the immune system). Active hepatitis B or C infection is defined by seropositive for hepatitis B surface antigen (HbSAg) or hepatitis C antibody.

- Healthy Volunteers: f

Study Arms:
- Cohort 1 treated with NY-ESO-1 T Cells (Type: EXPERIMENTAL): High NY-ESO-1 expression and the use of cyclophosphamide plus fludarabine as the lymphodepleting chemotherapy.
- Cohort 2 treated with NY-ESO-1 T Cells (Type: EXPERIMENTAL): Low NY-ESO-1 expression and the use of cyclophosphamide plus fludarabine as the lymphodepleting chemotherapy.
- Cohort 3 treated with NY-ESO-1 T Cells (Type: EXPERIMENTAL): High NYESO-1 expression and the use of cyclophosphamide only for lymphodepletion rather than fludarabine as the lymphodepleting chemotherapy.
- Cohort 4 treated with NY-ESO-1 T Cells (Type: EXPERIMENTAL): High NY-ESO-1 expression and the use of reduced dose cyclophosphamide plus fludarabine regimen as the lymphodepleting chemotherapy.

Based on this trial design, predict the completion outcome and termination type (if applicable).
