Long-term effect of a watch and wait policy versus immediate systemic treatment for asymptomatic advanced-stage non-Hodgkin lymphoma: a randomised controlled trial.

Background: Neither chemotherapy with a single-alkylating agent nor aggressive combination chemotherapy cures advanced stage low-grade non-Hodgkin lymphomas, even when combined with radiotherapy. Our aim was to compare administration of immediate chlorambucil treatment with a policy of delaying chlorambucil until clinical progression necessitated its use, in asymptomatic patients with advanced-stage, low-grade non-Hodgkin lymphoma.

Methods: 309 patients with asymptomatic, advanced-stage, low-grade non-Hodgkin lymphomas were recruited from 44 UK centres between Feb 1, 1981, and July 31, 1990.

A British National Lymphoma Investigation randomised trial of single agent chlorambucil plus radiotherapy versus radiotherapy alone in low grade, localised non-Hodgkins lymphoma.

Local radiotherapy (RT) alone was compared with radiotherapy plus continuous oral chlorambucil (RT+CHL) for the treatment of localised, low grade non-Hodgkins lymphoma (NHL) in a prospective randomised study of 148 patients. After a maximum of 18 years follow up there was no significant difference in overall survival or disease free survival between the two treatment groups. Age greater than 50 years and low serum albumin at diagnosis correlated with a poor prognosis in the series overall.

British National Lymphoma Investigation randomised study of MOPP (mustine, Oncovin, procarbazine, prednisolone) against LOPP (Leukeran substituted for mustine) in advanced Hodgkin's disease--long term results.

From 1979-1983, 299 patients with stage III or IV Hodgkin's disease (HD) were randomised to receive cyclical chemotherapy with MOPP (mustine, Oncovin, procarbazine, prednisone) or LOPP (Leukeran substituted for mustine). Two hundred and ninety patients were evaluable. There was no statistically significant difference between the complete remission (CR) rates (63% for MOPP, 57% for LOPP), percentage of patients remaining disease free at 5 years (38% for MOPP, 35% for LOPP) and overall survival at 5 years (65% for MOPP, 64% for LOPP).

Relationship of histopathologic features to survival and relapse in nodular sclerosing Hodgkin's disease. A study of 1659 patients.

Nodular sclerosing (NS) Hodgkin's disease (HD) with extensive areas of lymphocyte depletion or with numerous anaplastic Hodgkin's cells, termed Grade II NS, is associated with a poor response to initial therapy, an increased relapse rate, and decreased survival when compared with other NS variants, termed Grade I NS. The histopathologic subdivision of NS HD into Grade I and Grade II is easy to perform and provides essential prognostic information that is independent of stage. Patients with Grade II NS HD may require more aggressive initial therapy if their survival is to be improved.

Localized grade I non-Hodgkin's lymphoma: results of treatment with radiotherapy alone in 88 patients.

Eighty-eight patients entered into the British National Lymphoma Investigation with clinical stage I and II, grade I non-Hodgkin's lymphoma were treated initially with involved field radiotherapy alone. Eighty-one per cent presented with nodal disease. The duration of follow-up was 25-116 months, with a median of 54 months.
