Comparison of psychosocial adaptation of advanced stage Hodgkin's disease and acute leukemia survivors. Cancer and Leukemia Group B

BACKGROUND

The purpose of this study was to compare the long-term psychosocial adaptation of Hodgkin's disease and adult acute leukemia survivors.

PATIENTS AND METHODS

Two hundred seventy-three Hodgkin's disease (HD) and 206 adult acute leukemia (AL) survivors were interviewed by telephone concerning their psychosocial adjustment and problems they attributed to having been treated for cancer, using identical research procedures and a common set of instruments. The following measures were used: Psychosocial Adjustment to Illness Scale (PAIS); Brief Symptom Inventory (BSI); current Conditioned Nausea and Vomiting triggered by treatment-related stimuli (CNVI); Indices of Employment, Insurance and Sexual Problems Attributed to Cancer; Negative Socioeconomic Impact of Cancer Index (NSI). All participants had been treated on one of nine Hodgkin's disease or 13 acute leukemia Cancer and Leukemia Group B (CALGB) clinical trials from 1966-1988, and had been off treatment for one year or more (mean years: HD = 5.9; AL = 5.6).

RESULTS

HD survivors' risk of having a high distress score on the BSI was almost twice that found for AL survivors (odds ratio = 1.90), with 21% of HD vs. 14% of AL survivors (P < 0.05) having scores that were 1.5 standard deviations above the norm, suggestive of a possible psychiatric disorder. HD survivors reported greater fatigue (POMS Fatigue, P = 0.01; Vigor Subscales, P = 0.001), greater conditioned nausea (CNVI, P < 0.05), greater impact of cancer on their family life (PAIS Domestic Environment, P = 0.004) and poorer sexual functioning (PAIS Sexual Relationships, P = 0.0001), than AL survivors.

CONCLUSIONS

Treatment-related issues may have placed HD survivors at a greater risk for problems in long-term adaptation than AL survivors.

A comparative study of the long term psychosocial functioning of childhood acute lymphoblastic leukemia survivors treated by intrathecal methotrexate with or without cranial radiation

BACKGROUND

Although previous research has delineated medical, cognitive, and neuropsychologic late effects of central nervous system (CNS) prophylaxis for childhood acute lymphoblastic leukemia (ALL), it has been difficult to draw conclusions about the long term psychosocial sequelae of these treatments due to methodologic problems that led to inconclusive results in past studies. In the current study, the authors examined the long term psychosocial functioning of childhood ALL survivors who had been treated on a Phase III clinical protocol (Cancer and Leukemia Group B [CALGB] 7611) between 1976 and 1979, in which they were randomized to receive either 2400 centigray of cranial radiation (CRT) with intrathecal methotrexate (IT-MTX) or intermediate dose systemic methotrexate (IV-MTX) with IT-MTX.

METHODS

One hundred ten survivors of childhood ALL (mean age, 20.8 years) treated on CALGB 7611 who were age 14 years or older and disease free for at least 1 year were studied a mean of 14.7 years after their entry on CALGB 7611. In a telephone interview, a psychosocial assessment battery was administered to the patients, consisting of measures that assessed psychologic, sexual, social, and vocational functioning as well as any delayed physical effects.

RESULTS

Survivors who had received CRT + IT-MTX had significantly poorer academic achievement (P = 0.0001), poorer self-images with regard to their bodies (P = 0.001), and greater psychologic distress (P = 0.005).

CONCLUSIONS

Cranial radiation used to treat children with ALL has significant long term sequelae in terms of poorer academic achievement and psychosocial functioning. These data add weight to the conclusion that CRT prophylaxis should only be used to treat children who are at high risk of CNS relapse.

Quality of life for adult leukemia survivors treated on clinical trials of Cancer and Leukemia Group B during the period 1971-1988: predictors for later psychologic distress

BACKGROUND

To identify predictors of psychosocial adjustment for survivors of adult acute leukemia, the adaptation of 206 survivors (77% with acute myelogenous leukemia, and 23% with acute lymphocytic leukemia) treated on any of 13 Cancer and Leukemia Group B trials during the period 1971-1988 was examined.

METHODS

Survivors (median age, 41 years) who were at least 1 year from completion of all treatment (median, 5 years) were interviewed by telephone about psychologic symptoms; social, sexual, and vocational function; and beliefs about control over health. Standardized psychologic instruments were used to evaluate survivors' responses.

RESULTS

Most survivors adapted well; however, 14% were 1.5 standard deviations above normal on the Global Severity Index of the Brief Symptom Inventory. Predictors of greater psychologic distress included less education, younger age, anticipatory distress during chemotherapy treatment, and the combination of more medical problems after treatment with poorer family function. Anticipatory nausea and distress during chemotherapy predicted persistent visceral distress later, which occurred with reminders of treatment. Anticipatory vomiting predicted a greater tendency toward cancer-related intrusive thoughts and avoidance of reminders.

CONCLUSIONS

Patients experiencing anticipatory distress during treatment who are younger and less educated should be monitored for depressive syndromes later.

Preliminary guidelines for the treatment of distress

The National Comprehensive Cancer Network (NCCN) has provided those working in psycho-oncology with an important opportunity to examine the unique issues that relate to the development of psychological treatment guidelines. There are special problems in managing distress and in developing guidelines for its management. First, we need a nonstigmatizing word that encompasses all levels of psychological problems--from those considered "normal" to diagnosable psychiatric disorders. Distress is an example of such a word that can be used for a range of problems. It is objective and nonjudgmental. Attitudes of patients, staff, and institutions about psychological issues have created barriers to the prompt recognition and treatment of distressed patients. The major issue for implementation is the development of ways to rapidly identify distressed patients and triage them to the proper level of mental health intervention. A national plan by a multidisciplinary consortium, such as the NCCN, should be developed to recommend an agenda for clinical, educational, and research activities.

A psychosocial intervention for patients with soft tissue sarcoma

Support groups have increasingly been demonstrated to be an effective intervention in reducing psychological difficulties and emotional problems in patients with cancer. This report describes a pilot support group intervention based upon a modified version of Cain and colleagues' (1986) thematic counseling model for patients who have been treated for soft tissue sarcoma and are free of disease. The modified thematic counseling model consisted of eight group sessions that focused on providing information about soft tissue sarcoma, management of stress, relaxation techniques, and coping skills. In addition, time was set aside for general discussion of personal concerns. Common themes reported by patients were: communication with family, friends and physicians, anxiety about lack of information about soft tissue sarcoma, and major financial disruption because of their illness. At the conclusion of the eighth session, patients were given an informal survey and asked to rate the value of different aspects of the program for them. They reported that feelings of isolation, anger, depression, and anxiety significantly decreased; and their level of self-confidence increased dramatically. This pilot support group intervention is recommended as a model for enhancing the quality of life of patients with soft tissue sarcoma.

Do oncologists have an increasing interest in the quality of life of their patients? A literature review of the last 15 years

The aim of this review is to evaluate the extent to which Quality of Life (QoL) assessment has been incorporated into clinical oncological trials in the last 15 years. All phase II and III trials published in the Journal of Clinical Oncology, Cancer, The British Journal of Cancer and the European Journal of Cancer during the years 1980, 1985, 1990 and 1995 were reviewed (n = 827). During this period, while the number of studies assessing performance status (PS) increased from 15% in 1980 to 56% in 1995, the number of trials noting a QoL assessment increased only slightly, from 0% in 1980 to 3% in 1995. Moreover, only four of the 13 studies with a QoL evaluation met our criteria for adequate QoL assessment. Thus, despite an increasing interest in QoL, it is still rarely included as an objective in clinical trials, or adequately assessed.

Supportive telephone intervention for patients receiving chemotherapy. A pilot study

Psychosocial interventions have been shown to improve quality of life (QOL) for many cancer patients. A pilot study was conducted to assess the feasibility of a psychoeducational intervention for cancer patients receiving chemotherapy. Eight patients receiving chemotherapy for colorectal carcinoma participated. The intervention is based on a modification of Interpersonal Therapy. It consisted of four sessions, administered biweekly, using a manual format, by a psychiatric nurse clinician over the telephone. The participants also completed a set of QOL measures by telephone to assess tolerance of the planned assessment. The patients received assistance with treatment-related side effects, reported improved ability to communicate with their physician, and gained an understanding of the stresses they discussed. The patients felt satisfied with the emotional support and medical information provided. A randomized trial is planned to test the intervention for patients participating in a cooperative trial sponsored by the National Cancer Institute.

Quality of life of maxillectomy patients using an obturator prosthesis

BACKGROUND

The psychosocial adaptation of patients who had undergone a resection of the maxilla for cancer of the maxillary antrum and/or hard palate with the placement of an obturator prosthesis to restore speech and eating function was studied.

METHODS

Forty-seven patients were interviewed who had a maxillectomy with an obturator prosthesis at Memorial Sloan-Kettering Cancer Center, an average of 5.2 years (SD = 2.4 years) ago, 94% of whom had some of their soft palate resected. Interviews were conducted by telephone by a trained research interviewer, using a series of questionnaires to assess their satisfaction with the functioning of their obturator, and the psychological, vocational, family, social, and sexual adjustment. Measures included the Obturator Functioning Scale (OFS). Psychosocial Adjustment to Illness Scale (PAIS), Mental Health Inventory (MHI), Impact of Event Scale, and Family Functioning Scale.

RESULTS

Using multiple regression and discriminant function analyses, satisfactory functioning of the obturator prosthesis, as measured by the OFS, was found to be (1) the most highly significant predictor of adjustment, as measured by the PAIS (p < .0001) and the MHI Global Psychological Distress Subscale (MHI-GPD) (p < .001), and (2) significantly related to their perception of the negative socioeconomic impact of cancer upon their lives. The most significant predictor of better obturator functioning were the extent of resection of their soft palate (one third or less, p < .001), and hard palate (one fourth or less, p < .01). Specific aspects of obturator functioning that most significantly correlated with better adjustment (PAIS, MHI-GPD) were: less difficulty in pronouncing words (r = .40 and r = .51, respectively, p < .01), chewing and swallowing food (r = .27-.46, p < .05), and less change in their voice quality after surgery (r = .52 and r = .56, respectively, p < .001).

CONCLUSIONS

These findings suggest that a well-functioning obturator significantly contributes to improving the quality of life of maxillectomy patients.

Psychological symptoms and disease-free and overall survival in women with stage II breast cancer. Cancer and Leukemia Group B

BACKGROUND

The possible link between psychological factors and length of cancer survival has generated a literature of contradictory findings. Associations usually have not been found when general psychological symptoms are assessed. Associations usually have been found for predictors related to expressive versus repressive emotional coping (e.g., depression, "fighting spirit," hostility, and type C personality); however, even these associations have been relatively small, when compared with those for medical factors. Yet few studies have adequately controlled for medical and treatment-related factors.

PURPOSE

Within a Cancer and Leukemia Group B (CALGB) national clinical trial of four adjuvant therapy regimens for stage II breast cancer (CALGB 8082), this study prospectively examined the contribution of potential psychological predictors to length of disease-free and overall survival over a 15-year period.

METHODS

Subjects were 280 women with stage II breast cancer, out of a total of 899, who were randomly assigned to receive CMFVP (cyclophosphamide-methotrexate-fluorouracil-vincristine-prednisone) for two 6-week cycles or six 4-week cycles, then subsequently randomly assigned to receive or not to receive VATH (vinblastine-doxorubicin-thiotepa-fluoxymesterone). Subjects were recruited during the period between October 1980 and August 1984, inclusive, and followed until January 1996. Prior to chemotherapy, psychological symptoms were assessed using the Symptom Check List-90-Revised (SCL-90-R). SCL-90-R scores were trichotomized into categories representing high, medium, and low distress. Basic base-line sociodemographic data (including age, ethnicity, education, and marital status) and medical data (including lymph node status, estrogen receptor status, menopausal status, and performance status) were collected. Subjects with psychosocial data differed from those without psychosocial data solely in their higher percentage of classification in the mild limitation category of the Zubrod (Eastern Cooperative Oncology Group) performance status rating (subjects with psychosocial data: 14%; subjects without psychosocial data: 8%).

RESULTS

In stepwise Cox regression analyses that controlled for sociodemographic and medical variables, there was no significant predictive effect of the level of distress (as measured by the SCL-90-R trichotomized scores) on length of disease-free and overall survival of the study subjects. Risk ratios for low versus high distress were 1.01 (95% confidence interval [CI] = 0.62-1.66) for disease-free survival and 1.03 (95% CI = 0.58-1.82) for overall survival.

CONCLUSIONS

This study failed to provide evidence that psychological factors contributed to length of disease-free or overall survival of women who received adjuvant chemotherapy (either CMFVP alone or CMFVP followed by VATH) for treatment of stage II breast cancer.

IMPLICATIONS

In the context of far more potent medical factors, the contribution of psychological factors to disease-free and overall survival is likely to be relatively small. Future research should focus on specific theory-driven predictors rather than on general psychological symptoms. Moreover, it should be based on clinical studies using a controlled, prospective design, in which the effects of medical factors may be distinguished and psychological predictors are clear antecedents of survival outcomes.

Cardiorespiratory fitness and coronary heart disease risk factor association in women

OBJECTIVES

The purpose of this study was to examine the association between cardiorespiratory fitness and coronary risk factors in healthy, nonsmoking adult women.

BACKGROUND

A sedentary life-style is recognized as an independent risk factor for coronary heart disease, and increasing physical activity is strongly recommended to reduce this risk. However, studies examining the effects of increased physical activity on coronary heart disease risk factors in women are relatively few, and the findings have been equivocal.

METHODS

Subjects provided written informed consent, completed a questionnaire on medical history and performed an exercise tolerance test. Blood chemistry and lipid levels were determined from fasting blood samples. Three fitness categories were established on the basis of treadmill time to exhaustion and were adjusted for age.

RESULTS

The women in the lowest fitness category had less favorable lipid profiles, blood glucose levels, blood pressures and anthropometric indexes than those in the moderate and high fitness categories.

CONCLUSIONS

Moderate fitness (equivalent to 10 metabolic equivalents [METs]) is required to improve the coronary risk profile in women.

Breast reconstruction after mastectomy: who seeks it, who refuses?

Recent Food and Drug Administration hearings on silicone gel implants have drawn attention to the paucity of information about women who seek reconstruction after mastectomy compared with those who do not. New analyses of data gathered in the early 1980s address this issue. Three groups of mastectomy patients were compared: 117 women who sought and obtained delayed reconstruction, 26 who sought but decided against delayed reconstruction, and a comparison group of 53 who were not seeking reconstruction. Results indicated that although younger and more knowledgeable about reconstruction, patients in the reconstruction group were similar to those in the comparison group. However, the women who sought but chose not to proceed with reconstruction appear to have been at greater risk for physical and emotional disappointment with the results of reconstruction, which suggests that poor candidates for reconstruction may select themselves out at the time of consultation.

Miles run per week and high-density lipoprotein cholesterol levels in healthy, middle-aged men. A dose-response relationship

OBJECTIVE

To examine the association between miles run per week and high-density lipoprotein cholesterol levels in healthy middle-aged men.

BACKGROUND

Regular exercise increases levels of high-density lipoprotein cholesterol. However, the exercise requirements for such increases are not well defined.

METHODS

Healthy, nonsmoking men (n = 2906; age, 43 +/- 4 years) completed a questionnaire on health habits and physical activities and a symptom-limited exercise test. They were then stratified on the basis of the number of miles run per week. Six groups, with mileages of 0, 5, 9, 12, 17, and 31 per week, were established.

RESULTS

A gradual increase in high-density lipoprotein cholesterol level was observed with increased miles (0.008-mmol/L [0.308-mg/dL] increase in high-density lipoprotein cholesterol level per mile). Most of the changes were associated with distances of 7 to 14 miles per week. Levels of low-density lipoprotein cholesterol, triglycerides, and the ratio of total cholesterol to high-density lipoprotein cholesterol also improved with weekly mileage. The high-density lipoprotein cholesterol level correlated significantly with all exercise components, anthropometric measures, and alcohol consumption. Group comparisons disclosed significant differences (P < .05) in exercise time to exhaustion, miles run per week, body fat, body weight, and body mass index. Age and alcohol consumption were similar across groups.

CONCLUSIONS

These results indicate a dose-response relationship between miles run per week, high-density lipoprotein cholesterol level, and other lipoprotein-lipid levels. Most changes were noted in those who ran 7 to 14 miles per week at mild to moderate intensities. A mile-age threshold for changes in high-density lipoprotein cholesterol level was not observed. However, when compared with those of the nonexercising group, high-density lipoprotein cholesterol levels attained statistical significance at 7 or more miles per week.

Hypnotic efficacy and safety of triazolam administered during the postoperative period

This study examined the hypnotic efficacy and safety of short-term use of triazolam following elective surgery. One hundred women (ages 26-69) who had received 0.125 mg of traizalam the evening before breast cancer surgery were enrolled in a randomized, double-blind study comparing triazolam to placebo. Study medication was begun on the first or second evening following surgery, depending on the patient's level of postoperative alterness, and was administered in the hospital for three consecutive evenings. The starting dose of triazolam was 0.125 mg, with the option of increasing the dose to 0.25 mg on subsequent nights if sleep response was inadequate. Relative to patients in the placebo group, patients in the triazolam group reported significantly (p < 0.05) less difficulty falling asleep, fewer nightime awakenings, better overall sleep quality, and a greater sense of restfulness. No clinically significant adverse reactions were encountered and no adverse reactions occurred more frequently in the triazolam group than in the placebo group. Results indicate that administration of traizalam is a safe and effective method of improving sleep in patients recovering from surgery.

Depression and suicide in patients with cancer

Depression is a prevalent psychiatric syndrome in the cancer population. We review the spectrum of conditions in which depressive features are present, from normal responses to crises in cancer to depression secondary to organic causes. The different modalities of treatment, including pharmacologic, psychotherapeutic and social interventions, are described. Specific guidelines for the management of the suicidal cancer patient are given and physician-assisted death is discussed.

Quality of life of patients with prostate cancer and their spouses. The value of a data base in clinical care

BACKGROUND

Because of the dearth of information concerning the quality of life of patients with prostate cancer, a data base was established to examine the nature and extent of problems in patients' and spouses' adaptation and their interrelationships and to examine the effect of disease stage combined with treatment regimen on patients' quality of life.

METHODS

One hundred seventy-two patients and 83 spouses/partners completed quality of life questionnaires in a prostate cancer health education lecture series. The measures used were the European Organization for Research and Treatment of Cancer (EORTC) Prostate Cancer Quality of Life Questionnaire, the Intrusion subscale (IS) of the Impact of Event Scale; and Selby's QL Uniscale. Fifty-five percent of patients had received medical and/or surgical hormonal therapy, 28% had received a radical prostatectomy and/or radiation therapy only, and 18% had not been placed on any treatment.

RESULTS

Patients experiencing problems in adaptation were significantly more likely to have advanced stage disease; received surgical or medical hormonal therapy; and were reporting greater pain, fatigue, urinary problems, and deteriorating physical functioning. Spouses reported significantly greater psychological distress than did patients (EORTC Psychological Distress subscale, P < 0.001; IS, P < 0.001).

CONCLUSIONS

A two-stage clinical evaluation is recommended, in which quality of life questionnaires would initially be used to identify patients and spouses experiencing problems in adaptation for further evaluation by a mental health professional for appropriate treatment.

Quality of life in patients with limited small-cell carcinoma of the lung receiving chemotherapy with or without radiation therapy, for cancer and leukemia group B

Quality of life was assessed in 57 patients with limited small-cell carcinoma of the lung utilizing psychological scales that measured mood, functional status, and cognitive impairment. These patients received chemotherapy with or without radiotherapy to the primary tumor. All patients received prophylactic cranial radiation. Patients who received the combination of chemotherapy and radiotherapy to both the primary tumor and CNS had an increase in overall survival. However, because of the increased toxicity experienced by these patients, a decrease in quality of life was documented by measures of psychological distress when compared to patients receiving chemotherapy alone. The findings support the importance of utilizing quality of life measures in addition to measures of physical toxicity so that patients can make an informed choice regarding treatment options.

Artificial duplication of the R67 dihydrofolate reductase gene to create protein asymmetry. Effects on protein activity and folding

R67 dihydrofolate reductase (DHFR), encoded by an R plasmid, provides resistance to the antibacterial drug trimethoprim. This enzyme does not exhibit any structural or sequence homologies with chromosomal DHFR. A recent crystal structure of tetrameric R67 DHFR (D. Matthews, X. Nguyen-huu, and N. Narayana, personal communication) shows a single pore traversing the length of the molecule. Numerous physical and kinetic experiments suggest the pore is the active site. Since the center of the pore possesses exact 222 symmetry, mutagenesis of residues designed to explore substrate binding will probably also affect cofactor binding. As a first step in breaking this inevitable symmetry in R67 DHFR, the gene has been duplicated. The protein product, R67 DHFRdouble, is twice the molecular mass of native R67 DHFR and is fully active with kcat = 1.2 s-1, Km(NADPH) = 2.7 microM and Km(dihydrofolate) = 6.3 microM. Equilibrium unfolding studies in guanidine-HCl indicate R67 DHFRdouble is more stable than native R67 DHFR at physically reasonable protein concentrations. Microcalorimetry studies show native R67 DHFR undergoes fully reversible thermal unfolding. Unfolding can be described by a two-state process since a ratio of delta Hcalorimetric to delta Hvan't Hoff equals 0.96. In contrast, thermal unfolding of R67 DHFRdouble is not fully reversible and possesses an oligomerization component introduced by the gene duplication event.
