Criteria
Inclusion Criteria:

1. Inclusion Criteria: (Must be met within 28 days prior to initiating lymphodepleting
conditioning regimen) The first two patients enrolled in this protocol, if they have
undergone a previous autologous transplant, will need to be at least 6 months
post-transplant and/or have available prior cryopreserved autologous peripheral blood
stem cells. This criterion safeguards against the possibility that the lymphodepletion
regimen may lead to prolonged myelosuppression in this patient population.

2. Evidence of relapse or progression of neuroblastoma after autologous peripheral blood
stem-cell transplantation or similar aggressive therapy; high risk neuroblastoma that
is refractory to standard induction therapy.

3. Measurable disease, with at least one of the following: One or more measurable
radiographic abnormalities (X-ray, CT, MRI, PET); MIBG (metaiodobenzylguanidine) scan
with uptake at a minimum of 1 site; Bone marrow with tumor cells seen on routine
morphology (not by neuron specific enolase (NSE) staining or by immunocytology only).
If the only bony or soft tissue lesion available for evaluation has been previously
irradiated, the lesion must either a) have viable neuroblastoma on biopsy at least 4
weeks after radiation therapy or b) have measurable growth in the lesion after
radiation.

4. Donor must be related to the recipient.

5. Off all systemic chemotherapeutic agents or retinoids for at least 21 days prior to NK
infusion.

6. Platelets >/= 50,000 * 10^ 9/L and hemoglobin (Hgb) >/= 9 g/dL, unsupported by
transfusions in last seven days.

7. absolute neutrophil count (ANC) >/= 1,000 * 10^ 9/L, unsupported by cytokines in last
seven days.

8. Off prednisone or other immunosuppressive medications for at least 3 days prior to
both the lymphodepleting regimen and the NK infusion (This excludes chronic low dose
steroids for adrenal replacement which may be continued).

9. Karnofsky score or Lansky score >/= 60.

10. Adequate renal function defined as: Serum creatinine (Cr), for adults less than or
equal to 2 mg/dL, for children less than or equal to 2 mg/dL or less than or equal to
2 times upper limit of normal (ULN) for age (whichever is less). If these criteria are
not met, then recipient must have a Cr clearance greater than 60 mL/min/1.73m^2.

11. Adequate liver function defined as: Total bilirubin pyruvate transaminase (SGPT/Alanine aminotransferase, ALT) (unless Gilbert's disease or abnormal liver function due to primary disease).

12. Pulmonary symptoms controlled by medication and pulse oximetry greater than or equal
to 92% room air.

13. Females of childbearing potential (non childbearing is defined as premenarchal,
greater than one year post-menopausal or surgically sterilized) must have a negative
serum pregnancy test obtained within 2 weeks prior to registration and may not be
breast feeding during the study. All males and females of childbearing potential are
required to use a form of contraception considered effective and medically acceptable
by the Investigator during the time of the study.

14. Donor must meet standard medical eligibility criteria for allogeneic stem cell
donation and be able and willing to undergo apheresis.

15. Donor must have infectious disease marker testing [Hepatitis B, Hepatitis C, HIV,
cytomegalovirus (CMV), Syphilis (RPR), Chagas, human T-cell lymphoma virus (HTLV), and
West Nile Virus] and complete blood count (CBC), differential and platelet studies
that meet standard medical eligibility criteria for allogeneic blood stem cell
donation within 7 days of apheresis.

16. Donor, if a female of childbearing potential (non-childbearing is defined as
premenarchal, greater than one year post-menopause or surgically sterilized), must
have a negative serum pregnancy test obtained within 14 days of apheresis and may not
be breast feeding.

Exclusion Criteria:

1. Exclusion Criteria: These criteria apply to both the start of the lymphodepleting
regimen and to the NK infusion

2. Evidence of HIV (human immunodeficiency virus) disease or positive serology for HIV.

3. Currently requiring supplemental oxygen or on a ventilator.

4. Currently undergoing dialysis.

5. New detected cardiac arrhythmia not controlled with medical management within prior 72
hour period.

6. Hypotension requiring pressor support within prior 72 hour period.

7. Uncontrolled infection, daily fever greater than or equal to 39 degrees Celsius or new
positive culture for bacteria, fungus, or virus within the 72 hours prior to NK-cell
infusion.

8. Ascites requiring paracentesis within prior 72 hour period.

9. Seizure activity, clinically detectable encephalopathy or new focal neurologic
deficits within prior 72 hour period.

10. Donor may not have an uncontrolled infection within 7 days of apheresis.
