Randomized controlled trial to assess the effectiveness of a videotape about radiotherapy.

In a randomized controlled trial, the additional provision of information on videotape was no more effective than written information alone in reducing pre-treatment worry about radiotherapy. Images of surviving cancer patients, however, may provide further reassurance to patients once therapy is completed.

The concerns of patients under palliative care and a heart failure clinic are not being met.

Patients with a terminal illness, identified by palliative care teams working in Manchester, and patients attending a heart failure clinic, were asked to participate in a prospective survey to determine their main concerns. Data were collected from 213 palliative care (PC) patients (mostly with cancer) and 66 patients with heart failure (HF). The median ages of the two patient groups were similar, but the HF patients were more likely to be male and living with a partner; 13% of PC and 7% of HF patients reported that they had no carer. The PC patients had more district nurse, hospice, social work and physiotherapy input. The most frequently reported troublesome problems for PC patients were pain (49%), loss of independence (30%) and difficulty walking (27%). HF patients reported dyspnoea (55%), angina (32%) and tiredness (27%) as the most troublesome problems. From a checklist of symptoms, the frequency of tiredness (PC = 77%, HF = 82%) and difficulty getting about (PC = 71%, HF = 65%) were high in each group. Psychological problems were reported by 61% of PC and 41% of HF patients. Cardiac patients reported more breathlessness and cough than PC patients (83% vs 49% and 44% vs 26%, respectively). Reduced libido was more common in cardiac patients (42% vs 21%). Patient disclosure of troublesome problems to professional carers was high (>87% in both PC and HF patients). Documented action was greater for physical than social or psychological problems. For PC patients, documented action was recorded for 83% physical, 43% social/functional and 52% psychological problems. For HF patients documented action was recorded for 74% cardiac, 60% physical - non-cardiac, 30% social/functional and 28% psychological problems. Clearly many patients' troublesome problems were not being addressed. As a result of this study, specific action by health care professionals was taken in 50% of PC patients and 71% of HF patients. We plan to target specific educational events on the treatment of physical problems, psychological assessment and social service provision.

An audit of primary surgical treatment for women with ovarian cancer referred to a cancer centre.

Ovarian cancer is the commonest cause of gynaecological cancer death in the UK, and guidelines for initial surgery and staging of this disease are widely available. We report a retrospective audit of the surgical management of patients with newly diagnosed ovarian cancer referred to the Christie Cancer Centre in Manchester in 1996. The aim was to assess compliance with surgical guidelines. The authors found that the majority of patients (92%) presented via an outpatient clinic and for these individuals surgery was therefore elective. This mode of presentation should allow management by a small number of dedicated gynaecologists at each hospital, but up to seven consultants in each hospital performed surgery on a relatively small number of patients. Furthermore, less than half the patients underwent the recommended surgical procedure. Although some patients may have 'inoperable' disease, these data suggest that a greater compliance with national and international guidelines are required to provide an optimal level of care.

Follow up policy after treatment for Hodgkin's disease: too many clinic visits and routine tests? A review of hospital records.

OBJECTIVE: To examine the effectiveness of routine clinic review in detecting relapse after treatment for Hodgkin's disease. DESIGN: Review of hospital records. SETTING: Regional centre for cancer treatment and research. SUBJECTS: 210 patients with Hodgkin's disease recruited to a chemotherapy trial protocol between 1984 and the end of 1990 who had achieved a complete or partial remission after treatment. MAIN OUTCOME MEASURES: The number of clinic visits made by patients over the period of observation, the number of relapses occurring during that time, and the route by which relapse was detected. RESULTS: The 210 patients generated 2512 outpatient reviews, and 37 relapses were detected. Thirty relapses (81%) were diagnosed in patients who described symptoms, which in 15 cases had resulted in an earlier appointment being arranged. In only four cases (11%; 95% confidence interval 4% to 25%) was relapse detected as a result of routine physical examination on investigation of a patient who did not have symptoms. CONCLUSIONS: Relapse of Hodgkin's disease after treatment is usually detected as a result of the investigation of symptoms rather than by routine screening of asymptomatic patients. It is therefore proposed that the frequency of routine follow up visits should be reduced and greater emphasis placed on patient education. This should underline the importance of symptoms and encourage patients to arrange an earlier appointment if these develop.

Early mortality and the retinoic acid syndrome in acute promyelocytic leukemia: impact of leukocytosis, low-dose chemotherapy, PMN/RAR-alpha isoform, and CD13 expression in patients treated with all-trans retinoic acid.

All-trans retinoic acid (RA) has proven a major advance in the treatment of acute promyelocytic leukemia (APL). However, the proper management of patients who present with or develop leukocytosis during remission induction with all-trans RA is not established, nor is there a clear relation between leukocytosis and the development of the retinoic acid syndrome. We reviewed the course of our patients who underwent induction with all-trans RA to identify potential factors that might predict for the development of this syndrome and to identify which patients, if any, might specifically benefit from additional treatment with cytotoxic chemotherapy. Seventy-eight courses of all-trans RA therapy were administered to patients with a molecular diagnosis of APL. Initial and peak leukocyte counts, their rate of rise, leukocyte count criteria developed in Europe, and cell surface marker expression were all analyzed relative to subsequent development of both the RA syndrome as well as all causes of early mortality. The outcome of patients who received specific treatment for retinoid-induced leukocytosis was also examined. No factor was found to consistently predict for the development of the RA syndrome. Although the occurrence of the syndrome was positively associated with the peak value of the peripheral blood leukocyte count (P = .001), neither the initial leukocyte count nor the rate of rise in leukocyte counts on days preceding onset of the syndrome were sufficiently well-correlated to be clinically useful (P = .21). The leukocyte count criteria developed in Europe had a sensitivity of 62%, a specificity of 69%, and a positive predictive value that ranged from only 44% to 72%. However, we unexpectedly found that basal expression of CD13 (aminopeptidase N), a cell surface enzyme previously linked to tumor cell invasion and an inferior outcome in patients with acute myeloid leukemia, was highly associated with both development of the syndrome (P < .05) as well as an elevated leukocyte count (P = .006). Neither low-dose chemotherapy nor leukapheresis prevented development of the syndrome nor ameliorated its effects. In fact, 9 of 11 patients who received these interventions sustained fatal or near-fatal events, most of which were due to hemorrhage. However, early treatment with a short-course of high-dose corticosteroids halted progression of the syndrome in most cases. Finally, we found that expression of the type "A" isoform of PML/RAR-alpha (also known as bcr3 or "short") was associated with a significantly shorter duration of relapse-free and overall survival (P = .005).(ABSTRACT TRUNCATED AT 400 WORDS)

Treatment of acute promyelocytic leukemia with all-trans retinoic acid: an update of the New York experience.

In an ongoing study, we treated 79 patients with a molecular diagnosis of acute promyelocytic leukemia (APL) using all-trans retinoic acid (RA) for remission induction. Newly diagnosed patients received cytotoxic chemotherapy for consolidation, and previously treated patients received extended all-trans RA therapy, or a radionuclide-conjugated monoclonal antibody as post-remission treatment. Unlike studies in Europe, full-dose chemotherapy was not given during induction for patients who developed leukocytosis. Overall, 43 of 49 newly diagnosed patients (88%) and 25 of 30 previously treated patients (83%) achieved complete remission. We did not encounter de novo resistance to all-trans RA in any patient who was positive for PML/RAR-alpha rearrangements by reverse transcription polymerase chain reaction analysis. Ten patients died during induction from intracranial or pulmonary hemorrhage (six patients) or the 'retinoic acid syndrome' (four patients). The use of leukapheresis or low-dose chemotherapy (hydroxyurea or cytosine arabinoside) for drug-induced leukocytosis did not decrease early mortality. Compared to historical controls, early mortality was not affected by treatment with all-trans RA; however, both relapse-free and overall survival were significantly increased. Maintenance therapy with all-trans RA was associated with short remission duration, and relapses while taking the drug were universally associated with resistance to further retinoid treatment. We conclude that the use of all-trans RA for remission induction, with or without full-dose chemotherapy, has significantly increased the survival of patients with APL. While early mortality has not yet been reduced, the avoidance of full-dose chemotherapy during induction has significantly reduced early morbidity. The major outstanding clinical issue is the development of strategies that maximize safety in high-risk patients for whom intracranial hemorrhage remains the major cause of death.

Morbidity and costs of remission induction therapy with all-trans retinoic acid compared with standard chemotherapy in acute promyelocytic leukemia.

With the recent pressure to control health care expenditures, the costs of patient participation in clinical trials, especially in their earliest phases, have come under increasingly intense scrutiny. We therefore reviewed our experience in patients with acute promyelocytic leukemia (APL) who were treated during the first US trial of a new experimental drug, all-trans retinoic acid (RA). The purpose of the review was to evaluate parameters of patient morbidity and financial cost associated with the use of all-trans RA compared with standard chemotherapy for induction of complete remission in newly-diagnosed patients with APL. We retrospectively compared outcomes of consecutive patients treated during the first 2 years of our studies that used all-trans RA for remission induction (1990-1992) with an identical number of patients consecutively treated with standard chemotherapy (cytosine arabinoside plus an anthracycline) during the immediately preceding period (1985-1990). Responding patients in both groups received post-remission chemotherapy. Evaluation parameters included transfusions of packed red blood cells and platelets, use of anti-bacterial and anti-fungal drugs, duration of fever, time to remission, length of hospital stay, hospital charges, and both overall and relapse-free survival. Thirty patients were evaluated in each group. Complete remission was achieved in 26 patients (87%) treated with all-trans RA, and 24 patients (77%) treated with chemotherapy (p = 0.5). In the chemotherapy group, there were five early deaths (four from hemorrhage, one from sepsis); one other patient was resistant to treatment and died at 6 months. Four patients in the all-trans RA group died prior to response from complications of the 'retinoic acid syndrome'. The median time to complete response by all criteria was 41 days (range, 18-78) for the all-trans RA group and 50 days (range, 24-121) for patients who received conventional chemotherapy (p = 0.2). Looking only at patients who achieved remission, chemotherapy-treated patients required a significantly greater number of platelet transfusions (medians, 14 vs. 4; p < 0.001) and packed red blood cell transfusions (15 vs. 4; p < 0.001). Patients who received chemotherapy also experienced a significantly larger number of days with fever (13 vs. 6; p = 0.01) that was reflected in a greater median number of days on combination antibiotics (35 vs. 21; p = 0.001) and Amphotericin B (20 vs. 0; p < 0.001).(ABSTRACT TRUNCATED AT 400 WORDS)

All-trans retinoic acid for acute promyelocytic leukemia. Results of the New York Study.

OBJECTIVE: To evaluate the safety and efficacy of all-trans retinoic acid to induce complete remission and to examine its effects on duration of remission and survival in patients with acute promyelocytic leukemia. DESIGN: Phase II evaluation and comparison with historical control patients. SETTING: Tertiary care cancer referral center. PATIENTS: Consecutive patients with morphologic diagnoses of acute promyelocytic leukemia were treated during a 2-year period with all-trans retinoic acid (daily oral dose, 45 mg/m2). Newly diagnosed patients discontinued the drug approximately 30 days after they achieved complete remission, at which time they received three courses of combination chemotherapy. Patients treated with previous cytotoxic chemotherapy who then relapsed were continued on all-trans retinoic acid as "maintenance" therapy until they relapsed again. RESULTS: 56 patients entered the study: 34 were newly diagnosed and 22 had relapsed from previous treatment. Fifty-one patients subsequently were found to have the PML/RAR-alpha gene rearrangement indicative of acute promyelocytic leukemia, and 44 of these patients achieved complete remission (86%; 95% Cl, 76% to 96%). A distinctive respiratory distress syndrome developed in 13 patients (23%) during treatment, and 5 patients (9%; Cl, 3% to 20%) died of this complication. The 5 patients who lacked PML/RAR-alpha rearrangements were withdrawn and given chemotherapy. The 13 patients given all-trans retinoic acid alone as maintenance therapy (10 of whom had relapsed from a chemotherapy-induced remission) had a median duration of remission of only 3.5 months (range, 1 to 23 months). Only 3 of 19 patients who relapsed from a remission induced by all-trans retinoic acid could be brought into remission again using this drug. The median survival time of all newly diagnosed patients has not been reached, but it now exceeds 31 months (range, 0.4 to 36+ months). No decrease in the early mortality rate was observed compared with a historical control group composed of 80 consecutive, newly diagnosed patients treated only with chemotherapy at this center; however, overall survival was superior. CONCLUSIONS: All-trans retinoic acid is an effective agent to induce remission in patients with a molecular diagnosis of acute promyelocytic leukemia, but remissions are short and resistance develops rapidly. Although the incidence of early death was not reduced, the use of all-trans retinoic acid to induce remission, followed by cytotoxic chemotherapy for "consolidation," was associated with longer survival times when compared with historical controls treated only with chemotherapy. Additional studies to prevent or mitigate consequences of the "retinoic acid syndrome" and to identify specific patients who might benefit from earlier intervention with chemotherapy are needed to maximize the advantages of this approach.

The "retinoic acid syndrome" in acute promyelocytic leukemia.

OBJECTIVE: To describe a novel complication of therapy with all-trans retinoic acid in patients with acute promyelocytic leukemia. DESIGN: Case series. SETTING: Comprehensive cancer center. PATIENTS: Consecutive patients with a morphologic diagnosis of acute promyelocytic leukemia who underwent remission induction treatment with all-trans retinoic acid, 45 mg/m2 body surface area per day. MEASUREMENTS AND RESULTS: Nine of 35 patients (26%; 95% CI, 9% to 52%) with acute promyelocytic leukemia who were treated with all-trans retinoic acid developed a syndrome consisting primarily of fever and respiratory distress. Additional prominent signs and symptoms included weight gain, lower-extremity edema, pleural or pericardial effusions, and episodic hypotension. The onset of this symptom complex occurred from 2 to 21 days after starting treatment. Three deaths occurred; post-mortem examinations in two patients showed pulmonary interstitial infiltration with maturing myeloid cells. Six other patients survived, each achieving complete remission (five patients with all-trans retinoic acid only; 1 patient with chemotherapy). In six of the nine cases, the onset of the syndrome was preceded by an increase in peripheral blood leukocytes to a level of at least 20 x 10(9) cells/L. Certain therapeutic interventions, including leukapheresis, temporary cessation of therapy with all-trans retinoic acid, and cytotoxic chemotherapy in moderate doses were not useful after respiratory distress was established. However, the administration of high-dose corticosteroid therapy (dexamethasone, 10 mg IV intravenously every 12 hours for 3 or more days) early in the course of the syndrome resulted in prompt symptomatic improvement and full recovery in three of four patients. CONCLUSIONS: The use of all-trans retinoic acid to induce hematologic remission in patients with acute promyelocytic leukemia is associated in some patients with the development of a potentially lethal syndrome that is not uniformly accompanied by peripheral blood leukocytosis. Early recognition of the symptom complex of fever and dyspnea, combined with prompt corticosteroid treatment, may decrease morbidity and mortality associated with this syndrome.

Ethical issues in psychosocial research among patients with cancer.

The ethical implications of psychosocial research among patients with cancer are discussed. Two key issues were identified: obtaining informed consent and the impact of participating in research. Barriers to obtaining genuinely informed consent are described, as well as the costs and benefits of participation in research. Recommendations are made for the conduct of future research, relating to the removal of barriers to informed consent and monitoring the impact of the research process on its subjects.

How district health authorities organise cervical screening.

OBJECTIVES: To examine how district health authorities organised cervical screening with respect to Department of Health guidelines and to determine their assessment of the problems encountered. DESIGN: Postal questionnaire sent to all 190 district health authorities in England in 1989. PARTICIPANTS: 190 District health authorities in England. MAIN OUTCOME MEASURES: Population coverage of screening, quality of smear testing, and follow up of abdominal test results in comparison with national guidelines for district cervical screening services, and problems encountered by districts. RESULTS: Replies were received from 178 (94%) of districts, in 143 of which the person named as responsible for cervical screening contributed. All districts implemented a computer managed scheme, 150 by the target date of 31 March 1988, but not all of these conformed with the guidelines. At the time of the survey only just over half called women in the target age group of 20-64 and only 70% expected to meet the target date of 13 March 1993 for completing the call. Considerable variation was evident among the schemes with regard to how they dealt with issues related to population coverage, quality of testing, and follow up of abnormal results. The problems most commonly identified by the districts (n = 174) were laboratory workload (107, 61%), computer software (104, 60%), availability of resources (78, 45%), non-attendance (77, 44%), rate of opportunistic screening (62, 36%), and investigation and treatment (60, 34%). CONCLUSIONS: Current practice in running cervical screening schemes needs to be examined to determine the extent to which it contributes to the goal of reducing mortality from cervical cancer.
