RATIONALE: Observation is watching a patient's condition but not giving treatment unless symptoms appear or change. Lenalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. It is not yet known whether observation or lenalidomide is more effective in treating patients who are in complete or partial response after receiving previous gemcitabine hydrochloride or doxorubicin hydrochloride liposome for cutaneous T-cell lymphoma or mycosis fungoides/Sézary syndrome.
PURPOSE: This randomized phase III trial is studying observation to see how well it works compared with lenalidomide in treating patients who are in complete or partial response after receiving previous gemcitabine hydrochloride or doxorubicin hydrochloride liposome for stage IIB, stage III, or stage IV cutaneous T-cell lymphoma or stage IIB, stage III, or stage IV mycosis fungoides/Sézary syndrome.
- To determine if observation versus lenalidomide maintenance therapy after debulking with gemcitabine hydrochloride or pegylated liposomal doxorubicin hydrochloride with or without radiotherapy prolongs progression-free survival of patients with advanced stage IIIB or IV T-cell cutaneous lymphoma or mycosis fungoides/Sézary syndrome not previously treated with other intravenous chemotherapy.
OUTLINE: This is a multicentre study. Patients are stratified according to institution, response to debulking treatment (complete response vs partial response), and disease (mycosis fungoides [MF] vs erythrodermic MF/Sézary syndrome). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Beginning 4-6 weeks after completion of prior debulking therapy, patients undergo observation for 560 days.
- Arm II: Beginning 4-6 weeks after completion of prior debulking therapy, patients receive oral lenalidomide once a day on days 1-21. Treatment repeats every 28 days for 20 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed at 4 weeks and then every 3 months thereafter.

A group of disorders having a benign course but exhibiting clinical and histological features suggestive of malignant lymphoma. Pseudolymphoma is characterized by a benign infiltration of lymphoid cells or histiocytes which microscopically resembles a malignant lymphoma. (From Dorland, 28th ed & Stedman, 26th ed)
The act of regarding attentively and studying facts and occurrences, gathering data through analyzing, measuring, and drawing conclusions, with the purpose of applying the observed information to theoretical assumptions. Observation as a scientific method in the acquisition of knowledge began in classical antiquity; in modern science and medicine its greatest application is facilitated by modern technology. Observation is one of the components of the research process.
A leukemia/lymphoma found predominately in children and young adults and characterized LYMPHADENOPATHY and THYMUS GLAND involvement. It most frequently presents as a lymphoma, but a leukemic progression in the bone marrow is common.
B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.
