ABSTRACT

BACKGROUND: Cancer clinicians do not receive routine training in the psychosocial aspects of patient care such as how to communicate bad news or respond to patients who have unrealistic expectations of cure. Postgraduate workshops may be an effective way to increase interpersonal skills in managing these stressful patient encounters. METHODS: The authors conducted 2 half-day workshops for oncology faculty, one on breaking bad news and one on dealing with "problem situations." Participants met in a large group for didactic presentations and then small groups in which they used role-play and discussion to problem-solve difficult cases from their practices. The small groups were assisted in their work by trained physician facilitators. The workshops were evaluated by means of a follow-up satisfaction questionnaire as well as a self-efficacy measure, which was administered before and after the workshops. RESULTS: Twenty-seven faculty and 2 oncology fellows participated in the training programs. Satisfaction questionnaires showed that the programs met the educational objectives and were considered to be useful and relevant by the participants. Self-efficacy questionnaires revealed an increase in confidence in communicating bad news and managing problem situation cases from before to after the workshop. The majority of attendees welcomed the opportunity to discuss their difficult cases with colleagues. A number resolved to implement newly learned approaches to common patient problems they encountered frequently. CONCLUSIONS: Communication skills workshops may be a useful modality to provide training to oncologists in stressful aspects of the physician-patient relationship. Further research is needed to assess whether long term benefits accrue to the participants.

ABSTRACT

Because most patients now want to know the truth about their diagnosis and prognosis, the ability to discuss the cancer diagnosis, disease recurrence, or treatment failure, and to solicit patients' views about resuscitation or hospice care, are important verbal skills for oncologists and other oncology health care providers. Moreover, the ability to clearly articulate a treatment plan or elicit patient preferences for treatment are a prerequisite to informed consent. Despite these imperatives, clinicians do not routinely receive training in key communication skills that could enable them to accomplish these tasks. A body of literature is available, however, that identifies communication strategies that can (1) facilitate the establishment of a close rapport with the patient, (2) identify the patient's information preferences, (3) ensure comprehension of key knowledge and information, (4) address the patient's emotions in a supportive fashion, (5) elicit the patient's key concerns, and (6) involve the patient in the treatment plan. In this article, we use dialogues between a physician and a hypothetical patient with advanced ovarian cancer to illustrate how communication techniques can be applied to accomplish these goals. We identify important benefits of the use of these techniques for both the physician and patient, and pose several questions regarding the training of physicians in this area.

ABSTRACT

BACKGROUND & AIMS: Despite the high prevalence of the hyperplastic polyp, little is known about its etiology. The aim of this study was to assess the relationship between diet and other lifestyle factors and the presence of colorectal hyperplastic polyps. METHODS: Information on diet and other known or suspected risk factors for colorectal cancer or adenoma was collected among 81 subjects with hyperplastic polyps and 480 controls. RESULTS: The multivariate-adjusted odds ratio (OR) for hyperplastic polyps for individuals in the upper vs. the lower quartile was 0.30 (95% confidence interval [CI], 0.10-0.88) for dietary fiber, 0.32 (95% CI, 0.11-0.96) for dietary calcium, 0.90 (95% CI, 0.27-2.95) for total fat, and 2.02 (95% CI, 1.05-3.91) for alcohol consumption. Compared with individuals in the lower category, those in the upper category of body mass index had a higher risk for hyperplastic polyps (OR, 4.50; 95% CI, 1.84-10.97). Cigarette smoking was associated with a higher risk (OR, 1.97; 95% CI, 1.02-3.81 for > 20 pack-years vs. never), whereas an inverse association was seen for use of aspirin and other nonsteroidal anti-inflammatory drugs (OR, 0.29; 95% CI, 0.12-0.67 for once per day or more vs. never). CONCLUSIONS: Hyperplastic polyps share common lifestyle risk factors with colorectal adenomas and carcinomas.

ABSTRACT

BACKGROUND & AIMS: Precise quantitative and spatial analysis of cell cycle-related biomarkers in colonic crypts is often vital for studies of colon carcinogenesis and cancer prevention. To overcome the limitations of histology, confocal laser microscopy of microdissected whole crypts was used to quantitate S phase and mitotic cells. METHODS: Microdissected distal colonic crypts were studied in a modified rat starvation refeeding model. S phase cells were labeled in vivo with 5-bromodeoxyuridine. Mitotic cells were labeled with MPM2 (antibody to mitosis-specific epitope) and also assessed for chromatin morphology with propidium iodide. Sequential optical crypt sections, produced by confocal microscopy, were digitally imaged. S phase labeling indices per whole crypt were also compared with those derived by conventional immunohistochemistry. RESULTS: S phase and mitotic cells were clearly discriminated without background staining. The labeled S phase cell number and fraction per whole crypt were significantly decreased with starvation and increased with refeeding. Variability in the labeling index between whole crypts analyzed by confocal microscopy was significantly smaller than between histological crypt sections. Consequently, the intervention contributed to 92.2% of the total variability of the labeling index in whole crypts but only to 59% of the variability in histological sections. CONCLUSIONS: Major limitations of histology are overcome by crypt microdissection and confocal microscopic analysis. The total crypt cell population as well as labeled M phase and S phase cells can be imaged, localized, and quantitated with improved precision.

ABSTRACT

Use of calcium supplements has increased dramatically in recent years yet little is known about the effect of calcium supplementation on colon physiology. We supplemented 22 individuals with a history of resected adenocarcinoma of the colon, but currently free of cancer, with 2000 or 3000 mg calcium for 16 wk. The effects of supplementation on duodenal bile acids and important fecal characteristics including total fecal output, wet and dry weight, pH, bile acids (in solids and in fecal water), and concentrations and total excretion of calcium, magnesium, phosphates (organic and inorganic), unesterified fatty acids and total fat were determined. Calcium supplementation significantly decreased the proportion of water in the stool (P = 0.03), doubled fecal excretion of calcium (P = 0.006), and increased excretion of organic phosphate (P = 0.035) but not magnesium. Calcium supplementation significantly decreased the proportion of chenodeoxycholic acid in bile (P = 0.007) and decreased the ratio of lithocholate to deoxycholate in feces (P = 0.06). The concentration of primary bile acids in fecal water decreased after 16 wk Ca supplementation. Together with other reports of a "healthier" bile acid profile with respect to colon cancer when changes such as those observed in this study were achieved, these results suggest a protective effect of calcium supplementation against this disease.

ABSTRACT

Measurements of cell cycle phase fractions, particularly S-phase, are useful for studies of cell biology and carcinogenesis. Up-regulation of histone gene expression is tightly coupled to the G1-S-phase transition of the cell cycle, and mRNA levels rise 30-100-fold during S-phase. Labeling of histone H3 mRNA using in situ hybridization (ISH) was assessed as a measure of S-phase cells and compared with that found using in vivo 5-bromodeoxyuridine (BrdUrd) labeling in formalin-fixed rat colonic crypts under baseline, modified 72-h starvation, and 24-h refeeding conditions. The labeling index scored in single-labeled sections by histone H3 ISH tightly correlated with that found by in vivo BrdUrd labeling (r = 0.99, p < 0.0001) and clearly discriminated between the control, starved, and refed states (P < 0.001). In 180 crypt sections double labeled using histone H3 ISH and BrdUrd, 92% of 1572 labeled cells exhibited both nuclear BrdUrd and cytoplasmic histone H3 label. It is concluded that histone H3 ISH is an accurate measure of the S-phase fraction and provides an alternative to in vivo BrdUrd labeling in rat colon. This finding warrants validation in human studies.

ABSTRACT

A telephone survey was conducted among women 35 years old or older in Nueces County, Tex., to assess ethnic differences between Hispanic and non-Hispanic white women in self-reported cancer-screening practices and knowledge, attitudes, and beliefs about cancer and to evaluate the effect of ethnicity as a predictor for screening practices. A total of 233 Hispanic and 332 non-Hispanic white women participated in the survey. Hispanics were younger and had lower educational and income levels. Overall, Hispanics had lower rates than did non-Hispanics of lifetime mammography (65% versus 79%), clinical breast examination (86% versus 96%), monthly performance of breast self-examination (37% versus 49%), and lifetime fecal occult blood testing (36% versus 69%). After control for confounding factors, Hispanics were still less likely to have ever had a clinical breast examination and fecal occult blood test. Our results suggest the need for more culturally sensitive health promotion efforts to improve knowledge about cancer and early detection practices among Hispanic women.

ABSTRACT

Fecal occult blood test kits were distributed throughout the ethnically diverse Hawaiian Islands during a 3-week period in 1989. Occult blood was detected in 1,631 persons (11.8%). At least 83% of the participants with positive tests sought medical advice. Subsequently, 76 (4.7%) were diagnosed as having colorectal adenomas and an additional 1.4% had malignant neoplasms (3 gastric and 20 colorectal adenocarcinomas). Three quarters of the colorectal cancers were localized and node-negative. Participation in this program and the type of diagnostic studies done on participants with positive tests varied according to sex and ethnicity. Therefore, these demographic variables must be considered in designing fecal occult blood screening programs.

ABSTRACT

Because of its multiracial character, Hawaii presents a unique opportunity to carry out demographic investigations of the etiology of certain common cancers. Tumors with substantially different incidence rates among the major ethnic groups in the Islands, or between a given immigrant group and its country of origin, are of particular interest for such studies. Among the cancer sites meeting these criteria, nasopharynx, stomach, prostate, large bowel, liver, female breast, uterine corpus, ovary, bladder, and thyroid are particularly prominent.

ABSTRACT

Among 6860 50-77 year old men of Japanese ancestry examined in Honolulu 291 were known to have had a gastrectomy for benign gastric (189) or duodenal (102) ulcer, and 132 had documented peptic ulcer disease treated medically. Total serum cholesterol averaged 12 mg% lower in the surgical group than in the general population (p less than 0.01) while the medically treated men had intermediate values. Fasting lipoprotein determinations done in a sub-sample showed that the lower total cholesterol in the surgical group was due to depressed LDL, while HDL was higher in the operated men than in either the general population or the medically treated patients (p less than 0.01). The surgical patients were heavier users of cigarettes, beer and coffee and averaged about 10 lb. lighter than either the medically treated patients or the rest of the population. However, in multivariate analysis these differences did not not account for the differences in lipoproteins. A small decrement in blood pressure in the surgical patients as compared to the rest of the population became non-significant when weight and others factors were taken into account.

ABSTRACT

A 10-year prospective study of Hawaii Japanese males with partial gastrectomy shows that the age-adjusted mortality rates in men with partial gastrectomy were slightly higher than in those with an intact stomach, but the difference failed to achieve statistical significance. This excess of mortality is due, in part, to excess smoking by men who had ulcers of the stomach. Although death due to stroke and lung cancer showed the most substantial deviations from the base population, this can be attributed only in part to the tendency of men with these diseases to be smokers. Other factors, possibly related to nutrition, also contribute to the increased risk of mortality from these diseases. Death from coronary heart disease, an illness with a substantial association with smoking in men with an intact stomach was less frequent in men with gastrectomy but the difference was not statistically significant. It would appear that men with partial gastrectomy had other characteristics that weakened the impact of smoking upon coronary disease risk--low blood pressure, low serum cholesterol, low body weight and increased alcohol consumption.

ABSTRACT

A middle-aged woman suffered from chronic diarrhea and malnutrition as a result of a small intestinal infection with a coccidial protozoan--Cryptosporidium. This parasite has been found among a wide range of reptilian, avian and mammalian hosts, but rarely in human beings. This woman ultimately died as a result of disseminated toxoplasmosis of the type usually encountered in an adult whose immune responses were compromised. There was clinical evidence of both humoral and cellular immunologic incompetence, such as depressed levels of complement and immunoglobulins, and decreased T cell reactivity, respectively. The former could be accounted for on the basis of malnutrition causing deficient protein synthesis, and the latter may have been a manifestation of altered function of transformed T cells.

ABSTRACT

HLA antigens were identified for 99 Japanese patients with stomach cancer and for 222 controls in Hawaii. There were 68 patients with the intestinal/other histological type of stomach cancer and 31 patients with the diffuse type who may be genetically predisposed towards developing the disease. No significant differences in antigen frequency were noted between cases of the diffuse or intestinal/other histological type and the controls, or between the diffuse and intestinal/other type stomach cancer cases.

ABSTRACT

Some workers have associated fecal bile acids with colon cancer frequency. They suggest that the risk for colon cancer increases with a rise in the level of total and degraded fecal bile acids. The Japanese in Hawaii, who are at high risk for this cancer, had higher concentrations of deoxycholic acid (a degraded bile acid) in their fecal specimens than did the people in Akita, Japan, who are at low risk. However, the findings for the other bile acids were unremarkable or inconsistent. These data were suggestive, but not strongly supportive, of a relationship between fecal bile acid patterns and colon cancer risk.

ABSTRACT

Fecal samples of 165 Japanese men in Hawaii, age 43 to 74, were analyzed for bile acid content by their conversion to the methyl ester and the trimethylsilyl ether derivative followed by separation on a gas chromatograph. The arithmetic mean of total bile acids for the 165 specimens was 10.96 mg/g dry weight feces. Each of the following bile acids was detectable in over 77% of the fecal specimens: cholic, deoxycholic, lithocholic, and cholanic acid. The intake of Western foods was not positively correlated with the fecal content of secondary or modified bile acids, even though other workers have observed that these bile acids predominated in persons from Westernized countries. Two of the Japanese foods were negatively correlated with the levels of modified bile acids, which suggested that these foods contributed to a decrease in modified bile acids in fecal specimens. Fecal bile acid measurements appeared to be associated with age, but not with weight, height, or serum cholesterol levels.

ABSTRACT

It has been suggested that the risk of cancer, polyposis, and diverticulosis of the large bowel increases with bowel transit-time. Hence, Japanese inhabitants of Hawaii, in whom the risk of these diseases is high, would be expected to have longer transit-times than Japanese in Japan, in whom such risks are low. However, bowel transit-times were similar in Japanese groups. Stools from the Hawaii Japanese did weight significantly less than the specimens from Japan, and this factor may be indirectly related to the risk of colorectal cancer, polyposis, or diverticulosis in the Japanese.

ABSTRACT

The validity of a dietary recall questionnaire was tested among 50 men of Japanese ancestry, participating in a prospective epidemiologic study of gastrointestinal cancer in Honolulu. The questionnaire included 33 food items consumed in Hawaii and suggested as possibly carcinogenic or possibly protective. Estimated intakes of frequencies and amounts during the previous day and previous 7 days were obtained. The validity study consisted of a comparison of a 7 day diary of the frequencies and amounts of the 33 items with a subsequent recall of the same items. The sensitivity (proportion of men recording an item who subsequently recalled it) was better for 24 of the 33 items during the 7-day period than the 1-day period. The overall agreement between the two methods on whether the item was eaten or not was only marginally less for the 7 days than for the 1 day. Estimated intakes tended to be higher for the diary than the recall method. The Spearman rank correlation coefficients among persons recording the items generally were good (greater than 0.7) for items eaten habitually and for those associated with specific events. Further, rank order correlations for quantitative recell of particular food items has considerable validity and is a reasonable choice of method for studies of large groups concerning the role of particular food items in the etiology of cancer.
