Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Forty three patients with stage II-IV histologically confirmed mantle cell lymphoma (MCL) in need of systemic chemotherapy were enrolled at the H. Lee Moffitt Cancer Center between February 2004 and July 2008.

Reporting Groups
  Description
Vaccine and Conventional Therapy

Patients were treated with 3-6 cycles of chemotherapy +/- rituximab, with type and duration at the discretion of the individual clinician.

Chemotherapy: 6 courses of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) OR 3 courses of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with high-dose methotrexate and cytarabine (hyper-CVAD) for patients who have relapsed after CHOP.

Patients who achieve a partial or complete response after completion of chemotherapy proceed to autologous tumor cell-based vaccine therapy.

Patients who have stable or responding disease at 12 months receive 4 additional courses of booster vaccine and low-dose IL-2.

Treatment continues in the absence of disease progression or unacceptable toxicity.

  Hide Outcome Measure 2

Measure Type Secondary
Measure Title Occurrence of Related Serious Adverse Events (SAEs)
Measure Description Patients were monitored for toxicity every 4 weeks in clinic throughout the 4-month vaccination phase. This included clinical and laboratory evaluation (CBC, blood urea nitrogen (BUN), creatinine, electrolytes, liver function test (LFT), and serum LDH). Toxicity was defined according to the NCI Common Terminology Criteria for Adverse Events (CTCAE-3) Version 3.0 (www.ctep.cancer.gov). Grade 3 or higher SAEs attributed to vaccination: Toxicity was assessed in the 23 patients who received at least one vaccine injection.
Time Frame 4 months per participant  
Safety Issue Yes

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
With a median follow-up of 67 months, the median overall survival (OS) has not yet been reached.
