Second primary malignant neoplasms in patients treated for Hodgkin's disease at St Bartholomew's Hospital

Acute leukemia

This article provides a review of the acute leukemias with updated basic and practical information. The main emphasis is on techniques used to arrive at the correct diagnosis. Although morphology and cytochemistry were the mainstays of diagnosis in the past, new developments in immunophenotyping, cytogenetics, molecular biology, and in vitro assays have improved the understanding of this disease dramatically and enable the identification of new entities with distinct clinicobiologic features.

Second cancer after the treatment for Hodgkin's disease: a report from the International Database on Hodgkin's Disease

Twenty institutions/cooperative groups tabulated second cancers among 12,411 patients diagnosed with Hodgkin's disease between 1960 and 1987, giving 82,850 person-years of observation. Overall, 631 second cancers were observed, as compared with 223.25 expected (observed (O) to expected (E) ratio 2.83, p < 0.001) at least one year after the diagnosis of Hodgkin's disease. Second cancers were acute leukaemias (AL) in 158 cases as compared with 5.75 expected (O/E = 27.48, p < 0.001), non-Hodgkin's lymphomas (NHL) in 106 cases as compared with 3.34 expected (O/E = 31.77, p < 0.001), and solid tumors (ST) in 367 cases as compared with 214.16 expected (O/E = 1.71, p < 0.001), with no differences between males and females. Excess of ST was observed for the following anatomic sites: salivary gland, small intestine, colon, bronchus, pleura, bone, skin other than melanoma and thyroid in males; salivary gland, bronchus, pleura, skin other than melanoma and breast in females. While the excess of second AL and NHL was significant over the 1-14 year period after the start of initial therapy, that of second ST became apparent after the fifth year, increasing with time. Overall, the 15-year cumulative incidence rate of second cancer was 11.2%. It was 2.2%, 1.8% and 7.5% for second AL, NHL and ST, respectively. While the cumulative incidence of AL and NHL plateaued after 17 years, that of ST was still increasing. To analyse whether a particular treatment category was associated with an increased risk of second cancer, a prognostic study was performed on the 11,241 patients who achieved a complete remission and were continuously disease-free. Overall, 87 patients developed an AL, 68 a NHL, and 231 a ST. Combined modality treatments including MOPP or MOPP-like chemotherapy were associated with the higher risk of second AL (Relative risk (RR) = 17.11; p < 0.001) followed by age above 50 (RR > 4.50; p < 0.001), advanced clinical stage (RR > 2.50; p < 0.001), splenectomy (RR = 1.65; p < 0.05) and MOPP or MOPP-like chemotherapy used alone (RR = 2.20; p < 0.05). Factors associated with an increased risk of second NHL were age above 30 (RR > 3.5; p < 0.001), male gender (RR = 1.82; p < 0.05) and clinical stage III (RR = 1.70; p < 0.05).(ABSTRACT TRUNCATED AT 400 WORDS)

Management of stage II Hodgkin's disease: 15 years experience at St. Bartholomew's Hospital

One hundred seventy-seven consecutive patients with newly diagnosed stage II Hodgkin's disease (HD) (supradragmatic 157; infra diaphragmatic 20) were treated at St. Bartholomew's Hospital on the basis of pathologic stage (PS) in 84 (IIA 69; IIB 15) and clinical stage (CS) in 93 (IIA 33, IIB 60) between January 1968 and December 1984. The median follow up is 13 years. Overall, complete remission (CR) was achieved in 143 patients (75%) of whom 53 have had a recurrence. One hundred twenty-seven patients remain alive, the cumulative predicted survival at 15 yrs being 70%. Mantle radiotherapy was prescribed to 88 patients with supradiaphragmatic HD, of whom 75 entered CR and 9 achieved good partial remission (GPR) (95%). The duration of remission correlated strongly with ESR (greater than 50 mm/h) and mediastinal thoracic ratio (less than 33% vs. greater than 33%) in a multivariate analysis (p = 0.05 and 0.02, respectively). 46/88 patients remain in continuous first remission, the median duration of remission having not reached at 15 years. Combined modality therapy or chemotherapy alone was prescribed to 69 patients with supradiaphragmatic HD, CR being achieved in 51 patients and GPR in 8 at the completion of all therapy. 48/59 patients continue in first remission. The duration of remission of patients receiving combined modality therapy or CT alone was significantly longer (p = 0.002) than that of patients receiving RT alone, in spite of the fact that the former group comprised predominantly of patients with unfavourable features.(ABSTRACT TRUNCATED AT 250 WORDS)

Patterns of survival in patients with advanced Hodgkin's disease (HD) treated in a single centre over 20 years

A total of 164 consecutive adults with newly confirmed stage IIIB, IVA or IVB Hodgkin's disease (HD) commenced cyclical combination chemotherapy comprising mustine, vinblastine, prednisolone and procarbazine (MVPP) every 6 weeks (145 patients) or minor variants (19) at St Bartholomew's Hospital between 1968 and 1984. The median follow-up period is 14 years. Complete remission (CR) was achieved in 97/164 (59%) and partial remission (PR) in 23/164 (14%) with lesser responses or death being documented in 44. Achievement of CR correlated with stage, serum albumin and serum beta2 microglobulin level at presentation on univariate and multivariate analysis; 55/97 (58%) remain in continuous CR, the median duration of remission not having been reached. Twelve patients died in first remission; there have been 30 recurrences, one occurring after 13 years. Second remission was achieved in 17/30; 6/17 remain in continuous second remission and two have died in second remission. There have been nine second recurrences, third remission being achieved in 6/9. Two continue in third remission, two patients have died in third remission: 82/164 patients are alive with a minimum follow-up of 6 years. Eighty-two patients have died; 66 with evidence of HD, six with second malignancy, one each of haemorrhage and infection, eight of unrelated causes, the cause of death was unknown in one. The overall median survival from presentation is 14 years, being the same for patients in CR and PR with minimal residual abnormality (good partial remission, GPR), and being better for those for whom remission was achieved than those for whom it was not. The median survival following first recurrence is 4 years, being significantly longer for younger patients (less than 50 years). These results emphasise the importance of long-term follow-up to determine the clinical course of HD and are vital for planning experimental chemotherapy at the time of early treatment failure or recurrence.

Prognostic factors for survival in stage IIIB and IV Hodgkin's disease: a multivariate analysis comparing two specialist treatment centres

A multivariate analysis of prognostic factors was carried out on 301 patients with clinical or pathological stage III/IV Hodgkin's disease treated using the same combination chemotherapy (MVPP) at two centres (Christie Hospital, Manchester, 151 patients, St. Bartholomew's Hospital, London, 150 patients). There were no significant difference in CR or relapse free and overall survival at 5 and 10 years between the two groups. Cox analysis of the Christie data alone produced four significant factors for survival - age, sex, lymphocyte count and stage. The latter three factors showed the same trend for the St. Bartholomew's Hospital patients but failed to reach statistical significance. Analysis of the combined data showed all four factors to be of importance in predicting survival. Three different prognostic groups were identified which separated patients with good, intermediate or poor prognosis in both centres. The good prognostic group included patients aged less than 45 years, lymphocyte count greater than 0.75 x 10(9) l-1 and female patients with stage IIIB disease (5 year survival 85%). The rest were of poorer prognosis with male stage IV patients faring particularly badly (5 year survival 40%). Problems associated with the use of multivariate analysis to produce useful prognostic groupings in patients from different centres, are discussed.

Risk of therapy-related leukaemia and preleukaemia after Hodgkin's disease. Relation to age, cumulative dose of alkylating agents, and time from chemotherapy

391 patients treated intensively for Hodgkin's disease were followed for up to 15 years to evaluate the risk of therapy-related acute non-lymphocytic leukaemia (t-ANLL) and preleukaemia. Only two independent factors, patient age and cumulative dose of alkylating agents, were related to the risk of t-ANLL. The hazard rate of t-ANLL was roughly proportional to the square of patient age and to the total cumulative dose of alkylating agents. In 320 patients treated with alkylating agents the cumulative risk of t-ANLL increased steadily from 1 year after the start of treatment and reached 13.0% (SE 3.0) at 10 years after which time there were no further cases. Calculated from cessation of therapy with alkylating agents, however, the cumulative risk curve increased steeply during the first 1-2 years then gradually levelled out and no new cases were observed beyond 7 years. With a 15-year follow-up the general risk of solid tumours was not increased.

Unusual myeloid leukaemia in patient with Hodgkin's disease

An unusual case of leukaemia in a patient with Hodgkin's disease is described. The leukaemic blast cell population was typified by the presence of a substantial proportion of binucleate and multinucleate cells, many of which had the morphological features of Sternberg-Reed cells. The circulating and bone marrow blast cells were shown by immunophenotyping to be of myeloid origin.
