One hundred forty-eight patients with newly diagnosed follicular lymphoma were treated over a 12-year period. Twenty-two patients received radiotherapy for stage I and II disease, followed by adjuvant chemotherapy in 14 patients. One hundred thirteen were treated at presentation with short courses of chemotherapy, most often with single-agent chlorambucil for bulky stage II and stages III and IV disease. Thirteen patients were managed expectantly until there was evidence of disease progression. The median survival was 9 years. Patients treated with radiotherapy for stage I and II disease had an 83% relapse-free survival, but those with bulky stage II or stages III and IV disease treated with chemotherapy pursued a remitting and relapsing course with a 70% response rate at initial and subsequent retreatments, but a median duration of remission of 4 years in stage III and 1 year in stage IV disease (P = .041). Patients were observed in relapse and retreatment was administered as appropriate, once every 33 months on average. Poor prognosis patients could be identified by a combination of the presentation characteristics: B symptoms, hepatosplenomegaly, anemia, and abnormal liver function. These factors predicted a poor response to treatment and correlated with a short survival. Histologic subgroups were not associated with differences in survival, but transformation to a diffuse high-grade lymphoma was observed in 23 of the 72 patients (32%) at risk, with a median follow-up of 6 years and 6 months, and was associated with a very poor prognosis. The present treatment strategy has proved successful for most patients with localized disease and those older patients with indolent small volume disseminated follicular lymphoma. New approaches are being investigated for the younger poor prognosis patients.
SummarySeventy-three patients with active acromegaly were treated for three to 25 months with bromocriptine 10-60 mg/day. Seventy-one patients showed symptomatic and objective clinical improvement. This included reduction in excessive sweating, hand and foot size, and the number of headaches; improved facial appearance; and increased energy and libido. Abnormal visual fields became normal in two patients, one of whom had concomitant radiotherapy. Mean circulating growth hormone levels, obtained by averaging serial samples through the day, fell by more than 7 pg/l or became undetectable in 58 patients (79%) but did not reach normal values: only 15 patients had mean levels on treatment of 5 ,tg/l or less. Twenty-three patients were diabetic before treatment, and glucose tolerance became normal in 15 and improved in a further five. Provided the drug was started slowly side effects were minor when compared with the considerable clinical benefit obtained.
Development of a new testing machine, which stabilizes the pelvis, allowed us to evaluate the lumbar extensor muscles before and after training. Fifteen healthy subjects (29.1 +/- 8 years of age) trained 1 day per week for 10 weeks and 10 healthy subjects (33.7 +/- 16 years of age) acted as controls. Training consisted of 6 to 15 repetitions of full range of motion variable resistance lumbar extension exercise to volitional fatigue and periodic maximal isometric contractions taken at seven angles through a full range of motion. Before and after the 10 week training period, subjects completed a maximum isometric strength test at seven angles through a 72 degrees range of motion (0 degrees, 12 degrees, 24 degrees, 36 degrees, 48 degrees, 60 degrees, and 72 degrees of lumbar flexion). The training group significantly improved in lumbar extension strength at all angles (P less than or equal to 0.01). The result at 0 degrees (full extension) showed an increase from 180.0 +/- 25 Nm to 364.1 +/- 43 Nm (+102%) and at 72 degrees (full flexion) from 427.4 +/- 44.1 to 607.4 +/- 68 (+42%) Nm. Results from the control group showed no change (P greater than or equal to 0.05). The magnitude of gain shown by the training group reflects the low initial trained state of the lumbar extensor muscles. These data indicate that when the lumbar area is isolated through pelvic stabilization, the isolated lumbar extensor muscles show an abnormally large potential for strength increase.
