Spontaneous infarction of superficial lymph nodes.

Five cases of extensive infarction of lymph nodes were traced in just over 16 years' surgical material. All presented with painful swelling in a superficial lymph node chain. None was diagnosed clinically; two were interpreted as fibroadenoma of the axillary tail of the breast, and two as a femoral hernia. Microscopically the lymph nodes in the first three weeks after infarction were characterized by extensive necrosis of medullary and cortical lymphoid cells, but the central reticulin architecture and a narrow, incomplete rim of viable subcapsular lymphoid tissue were preserved. Reactive perinodal inflammation and the formation of granulation tissue resembled the reaction to myocardial infarction. The late stage of the lesion was characterized by incomplete regeneration of lymphoid tissue in the lymph nodes. The lesions appeared attributable to thrombosis of veins within the substance and the hila of the nodes.

Combination chemotherapy in generalized Hodgkin's disease.

Fifty-two patients with generalized Hodgkin's disease were treated with a combination of mustine hydrochloride, vinblastine, procarbazine, and prednisolone. Complete remissions were obtained initially in six out of seven patients (86%) who had previously received no treatment, in 15 out of 19 (79%) who had had only radiotherapy in the past, and in 9 out of 26 (35%) who had previously been given chemotherapy with or without radiotherapy. Of these 30 patients in whom a complete remission was obtained 22 have been free of any symptoms or signs of disease for periods ranging from 4 to 22 months. The response to treatment was rapid, and toxicity was not a major problem, except in those who had previously been treated with cytotoxic drugs used continuously and not in courses. A comparative trial of radiotherapy and combination therapy in the treatment of Stage III Hodgkin's disease is strongly recommended.

Prolonged survival after portal decompression of patients with non-cirrhotic intrahepatic portal hypertension.

In a series of 251 good-risk patients undergoing portal decompression for intrahepatic portal hypertension, one fifth have been found not to have hepatic cirrhosis. Of these, 44 had only minor changes in hepatic architecture, and the clinical features and subsequent course have been compared and contrasted with a group of 201 cirrhotic patients who underwent portal decompression for similar indications. The degree of portal hypertension was comparable in both groups and it was not possible confidently to differentiate the condition from hepatic cirrhosis on either clinical or biochemical grounds in the individual case. The histological lesion was not progressive in the non-cirrhotic group and this was reflected in the far better survival of these patients. After five years 83% (30 of 36) of this group were alive compared with 43% (65 of 152) of the cirrhotic patients. After 10 years the cumulative survival was 77% (20 of 26) for those without cirrhosis, contrasted with 22% (19 of 87) for the cirrhotic patients.

The histological diagnosis of toxoplasmic lymphadenitis.

The commonest presenting sign of acquired toxoplasmosis in man is enlargement of superficial lymph nodes. The persistence of the nodes may lead to a suspicion of malignant lymphoma and the diagnosis then hinges on the lymph node biopsy. Three cases of toxoplasmic lymphadenitis are described in each of which the diagnosis was unsuspected clinically. The chance discovery of a toxoplasma cyst in the lymph node section of Case 1 led to the correct diagnosis, after an initial diagnosis of Hodgkin's disease had been made. In the other two, strikingly similar histological changes in the lymph node biopsies suggested the diagnosis, which was confirmed serologically in each case. The histological changes are described and the clinical and pathological aspects of toxoplasmic lymphadenitis are briefly reviewed, with special reference to the differentiation from malignant lymphomatous conditions and to the specificity of the histological picture. It is concluded that the histology is, in many instances, sufficiently distinctive for a tentative diagnosis of toxoplasmic lymphadenitis to be made on the lymph node biopsy. The diagnosis should always be confirmed by isolation of the parasite or by serological tests. It is exceedingly rare for toxoplasma cysts to be found in lymph nodes and only one previous observation of this kind has been reported.

The management of localized, infradiaphragmatic Hodgkin's disease: experience of a rare clinical presentation at St Bartholomew's Hospital.

Between 1969 and 1982, 23 previously untreated patients with Hodgkin's disease (HD) confined to infradiaphragmatic sites were treated at St Bartholomew's Hospital. The distinguishing clinical characteristics of the patient population were a male: female ratio of 20:3. The mean age was 39 years, which was significantly older (P less than 0.05) than the mean age of patients with supradiaphragmatic HD (32 years) referred during the same period. Sixteen patients underwent formal pathological staging while one additional patient underwent a diagnostic laparotomy without splenectomy. The final pre-treatment stages were PS IA: 5; PS IIA: 11; CS IIA: 1; PS IIB: 1; CS IIB 5. Splenic involvement correlated closely with the number of nodal sites involved, being detected in 1/7 patients with one site only compared with 8/9 with more (P less than 0.001). Complete remission (CR) was achieved in 21 (91 per cent) patients: 12/12 following 'inverted Y' radiotherapy (RT) and 9/11 following combination chemotherapy. Twenty patients remain alive and 18 continue without recurrence of HD between 15 months and 12 years. All patients who failed to enter CR or who relapsed had presented with three or more sites of involvement or with constitutional ('B') symptoms. These results confirm the generally good prognosis of this uncommon presentation of HD and also suggest that prognosis is determined by the bulk of disease rather than its precise anatomical localization, provided that appropriate therapy is administered.

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

The incidence of second malignant neoplasms (SMN's) was investigated in a group of 529 patients with Hodgkin's Disease (HD) treated at St Bartholomew's Hospital (SBH). SMN's were seen in 27 of these patients giving an incidence rate three and a half times that expected in an age and sex matched normal population (p = much less than 0.001). The incidence rate was higher in those receiving multiple chemotherapy and radiotherapy for relapsed HD compared with those receiving primary radiotherapy, chemotherapy or chemotherapy with adjuvant radiotherapy (p = 0.02). However, the increased incidence rate in those patients treated with chemotherapy on relapse, may reflect in part a delayed effect of their primary therapy, since the incidence rate in the primary treatment group only becomes significantly raised after six years. When allowance was made for this delay the difference between the two groups was no longer significant. The incidence rates for Non-Hodgkin's Lymphoma (NHL) and myelogenous leukaemia were 32 and 57 times those expected, compared with only two and a half times the expected rate for non-haematological SMN's (p = much less than 0.001). The four acute myeloid leukaemias (AML) all occurred within five years of treatment compared to wide-ranging intervals between treatment and occurrence of SMN in the other groups. The increased incidence of NHL may be an alternative expression of lymphoid abnormality rather than a treatment-related occurrence. Multiple SMN's were diagnosed in three patients. This represented a highly significant (p = much less than 0.001) increase over the expected incidence of multiple neoplasia in the general population. Several factors may contribute to the development of SMN's in HD, including an inherent disposition of HD itself. The time-dependent incidence pattern of SMN's with a delay followed by an increased incidence rate, suggests that treatment plays a key role. It is not yet clear whether more intensive, or multiple treatments add to the risk accrued for the initial treatment.

Management of localized non-Hodgkin's lymphoma: the experience at St. Bartholomew's Hospital 1972-1985.

A retrospective study of 202 patients with clinical stage I and II non-Hodgkin's lymphoma managed at St. Bartholomew's Hospital between 1972 and 1985 was conducted. Patients were treated either with radiotherapy alone, radiotherapy and adjuvant chemotherapy, or chemotherapy (with or without adjuvant radiotherapy). At the onset of the study it was intended that all patients with localized NHL should be treated with involved field radiotherapy and adjuvant 'CVP'. As it became apparent that this was inadequate for some patients and too toxic for others a flexible approach was later adopted. Treatment selection depended on age, volume, distribution of disease and histological subtype. The actuarial 5 year overall survival for the whole group was 70 per cent. Death from lymphoma after 5 years was very rare. Increasing age and high grade histology were highly significant adverse prognostic factors by multivariate analysis. The results for patients with high grade and low grade histology were therefore analysed separately, as was the outcome for patients presenting with either gastrointestinal or skin lymphomas. During the latter part of the study period intensive chemotherapy was given as the initial treatment to patients with high grade histology and bulky, or stage II disease. Twenty out of 24 patients so treated achieved complete remission and only one has relapsed to date. These results are encouraging and probably explain the absence of a difference in prognosis between patients with stage I and IE disease and those with stage II and IIE disease observed over the whole period of the study. Remission was achieved in the overwhelming majority of patients with low grade histology for whom radiotherapy was selected as primary therapy. Duration of remission was better in patients who received adjuvant chemotherapy than in those treated with radiation alone, but no difference in overall survival was observed between these groups. Neither stage nor the presence of a follicular histological pattern correlated with prolonged survival in patients with low grade histology.

Lymphoplasmacytoid and small cell centrocytic non-Hodgkin's lymphoma--a retrospective analysis from St Bartholomew's Hospital 1972-1986.

Lymphoplasmacytoid (lpc) and small cell centrocytic (scc) lymphoma are the two major sub-types of diffuse low grade non-Hodgkin's Lymphoma (NHL) within the Kiel classification. The presentation features and outcome for all 112 patients with these diagnoses (60 lpc, 52 scc) managed at St Bartholomew's Hospital between 1972 and 1986 are presented. The outcome for these patients is compared with that for patients with follicular and high grade lymphomas managed at this hospital during the same period. Nineteen of the 112 patients had localized (stages I-IIE) disease. In 18 of these cases the primary site of disease was extranodal, the gastrointestinal tract being involved in 12 cases. The survival for patients with localized disease was excellent. Eighteen are currently alive with median follow-up of 8 years. Ninety-three patients had advanced disease. A high incidence of splenomegaly, hepatomegaly, bone marrow and peripheral blood involvement was observed in both histological subgroups. A monoclonal paraprotein band was detected in the serum of nearly 50 per cent of patients with advanced lpc lymphoma. Patients with advanced disease were treated with either chlorambucil or cyclophosphamide, vincristine and prednisolone (CVP). The outcome was similar for both histological groups. Survival for these patients was poor (median 40 months) with less than 20 per cent surviving 5 years. Advanced age, elevated aspartate transaminase and failure to respond to treatment were identified by multivariate regression analysis as adverse prognostic factors.
