The purpose of the trial is to establish whether adjuvant therapy with lenalidomide + dexamethasone after radiotherapy can improve progression free survival in patients with high risk solitary bone plasmacytoma compared with RT only.

Solitary bone plasmacytoma (SBP) is a localised proliferation of malignant plasma cells (PCs) in the skeleton. The annual UK incidence is 0.4/100,000 (lower than multiple myeloma (MM)) with a peak age incidence at 68 years and there are estimated to be about 260 new cases per year in the United Kingdom (UK). The majority of patients with SBP ultimately progress to myeloma and this is likely due to occult disease not detected by conventional staging methods. Standard care for these patients is involved field radiotherapy (IFRT), but despite radical doses, two-thirds develop multiple myeloma at a median of 2 years, more so if there are high risk features.

The IDRIS Trial is a phase III study where the investigators hope to demonstrate that adjuvant lenalidomide + dexamethasone following IFRT prevents the development of multiple myeloma in patients with high risk solitary bone plasmacytoma. Whilst a proportion of solitary bone plasmacytoma is cured with IFRT, it is clear that the majority will progress to multiple myeloma. The investigators are seeking to prevent this outcome by using adjuvant therapy in this study.

Phase III Randomised Trial of Immunomodulatory Therapy in High Risk Solitary Bone Plasmacytoma

Progression free survival rate and will be analysed using Kaplan-Meier survival analysis. PSF time will be measured from date of randomisation until progression or death.

Time from randomisation to death of any cause will be compared between arms

The time from end of radiotherapy to first date of any non-protocol treatment for plasmacytoma or myeloma will be compared between arms

The number and proportion of patients on the lenalidomide + dexamethasone arm who achieve normalisation of the SFLCr and/or the disappearance of aberrant plasma cell phenotype following Lenalidomide + Dexamethasone treatment will be documented.

During treatment and follow up, the frequency and percentages of adverse events with a maximum severity of grade 3-5 (according to CTCAE v4.03) will be collected.

Second primary malignancies occurring during treatment and in the 5 years after treatment will be recorded in patients on the lenalidomide + dexamethasone arm

Compliance with lenalidomide and dexamethasone treatment will be assessed using descriptive statistics. The number of reductions, delays and omissions of lenalidomide and dexamethasone will be presented as well as the median time on study treatment

RATIONALE: A PET scan may help doctors learn how the cancer responded to combination chemotherapy and whether radiation therapy is also required.

PURPOSE: This randomized phase III trial is studying giving a PET scan to see how well it works in deciding whether patients who have received combination chemotherapy for stage IA or stage IIA Hodgkin lymphoma also need radiation therapy.

OBJECTIVES:

* Determine whether patients with stage IA or IIA Hodgkin lymphoma who have a negative fludeoxyglucose F 18 positron emission tomography (FDG-PET) imaging after 3 courses of chemotherapy comprising doxorubicin hydrochloride, bleomycin sulfate, vinblastine, and dacarbazine (ABVD) require consolidation radiotherapy (to areas of previous involvement) in order to delay or prevent disease progression.

OUTLINE: Patients receive doxorubicin hydrochloride IV, bleomycin sulfate IV, vinblastine IV, and dacarbazine IV (ABVD) on days 1 and 15. Treatment repeats every 28 days for 3 courses. On day 15 of the third course of chemotherapy, patients undergo a CT scan of the neck, thorax, abdomen and pelvis. Patients with nonresponsive disease or progressive disease are removed from the study. Patients who achieve response undergo fludeoxyglucose F 18 positron emission tomography (FDG-PET). Patients with a positive FDG-PET scan receive an additional course of ABVD and undergo involved field radiotherapy. Patients with a negative FDG-PET scan are randomized to 1 of 2 treatment arms.

* Arm I: Within 6 weeks after completion of course 3 of chemotherapy, patients undergo involved field radiotherapy to disease areas.
* Arm II: Patients receive no further treatment. After completion of study therapy, patients are followed up every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter.
