Inclusion Criteria

• Histologic diagnosis of Classical Hodgkin lymphoma, confirmed by the department of hematopathology at MSKCC. Patients who have relapsed after an autologous stem cell transplant must have a biopsy after transplant to confirm relapsed Hodgkin's disease. Patients who have relapsed after an allogeneic transplant must also have a biopsy posttransplant.
• Age > or = to 18
• All patients must have PET avid measurable disease.
• Last chemotherapy > or = to 4 weeks from the start of Bendamustine HCl
• Receiving no other treatment for HL
• Patients must have normal baseline cardiac function based upon echocardiogram or gated blood pool scan (MUGA) with an ejection fraction > or = to 50%
• Patients must have a serum creatinine of 1.5 mg/dl creatinine clearance must be >60 ml/minute.
• Patients must have ANC>1000/mcl and Platelets>100,000/mcl.
• Patients must have a bilirubin level of < 2.0 mg/dl in the absence of a history of Gilbert's disease (or pattern consistent with Gilbert's).
• Patients must be Hepatitis B surface antigen and Hepatitis B core antibody negative and Hepatitis C negative.
• Patients must have failed an autologous stem cell transplant or be ineligible for an autologous stem cell transplant due to chemo-refractory disease(as defined as <50% response to standard salvage chemotherapy).
• Women who are pre-menopausal must have a negative pregnancy test
• Subjects must agree to use appropriate contraception until 4 weeks after the completion of chemotherapy.
• Patients must be HIV negative.
• If patients have a history of malignancy other than cutaneous basal cell or squamous cell carcinoma, they must be disease-free for ≥ 5 years at the time of enrollment.

Exclusion Criteria

• Patients with either parenchymal brain or lepto-meningeal involvement.
• 7 or more consecutive days of prednisone therapy prior to therapy.

This includes patients with uncontrolled infection, chronic renal insufficiency, myocardial infarction within the past 6 months, unstable angina, cardiac arrhythmias other than chronic atrial fibrillation and chronic active or persistent hepatitis
• History of any malignancy for which the disease-free interval is <5 years, excluding curatively treated cutaneous basal cell or squamous cell carcinoma and carcinoma in-situ of the cervix.
• Relapse <6 months post allogeneic stem cell transplant
