Reductions in sleep quality and circadian activity rhythmicity predict longitudinal changes in objective and subjective cognitive functioning in women treated for breast cancer.

PURPOSE: To examine long-term cognitive effects of chemotherapy and identify predictors among women with breast cancer (WBC). PATIENTS AND METHODS: Sixty-nine WBC scheduled to receive chemotherapy, and 64 matched-controls with no cancer, participated. Objective and subjective cognition, total sleep time, nap time, circadian activity rhythms (CAR), sleep quality, fatigue, and depression were measured pre-chemotherapy (Baseline), end of cycle 4 (Cycle-4), and one-year post-chemotherapy (1-Year). RESULTS: WBC showed no change in objective cognitive measures from Baseline to Cycle-4 but significantly improved from both time points to 1-Year. Matched-controls showed an increase in test performance at all time points. WBC had significantly higher self-reported cognitive dysfunction at Cycle-4 and 1-Year compared to baseline and compared to matched-controls. Worse neuropsychological functioning was predicted by less robust CARs (i.e., inconsistent 24 h pattern), worse sleep quality, longer naps, and worse cognitive complaints. Worse subjective cognition was predicted by lower sleep quality and higher fatigue and depressed mood. CONCLUSION: Objective testing showed increases in performance scores from pre- and post-chemotherapy to one year later in WBC, but matched-controls showed an increase in test performance from baseline to Cycle-4 and from Cycle-4 to 1-Year, likely due to a practice effect. The fact that WBC showed no practice effects may reflect a form of learning deficit. Compared with the matched-controls, WBC reported significant worsened cognitive function. In WBC, worse objective and subjective cognitive functioning were predicted by worse sleep and sleep-related behaviors (naps and CAR). Interventions that target sleep, circadian rhythms, and fatigue may benefit cognitive function in WBC.

Prostate-Specimen Antigen (PSA) Screening and Shared Decision Making Among Deaf and Hearing Male Patients.

Some deaf men who use American Sign Language (ASL) experience barriers in patient-physician communication which may leave them at disparity for shared decision making compared to hearing men. Transparent communication accessibility is needed between deaf male ASL users and their physicians to maximize the benefit to risk ratio of using the prostate-specific antigen (PSA) as a screening tool for early detection. The objective is to compare shared decision-making outcomes between deaf and hearing males who are (1) age-eligible for PSA screening and (2) younger than 45 years old with a family history of cancer. An accessible health survey including questions about PSA test, PCC, modes of communication, and cancer history was administered in ASL to a nationwide sample of deaf adults from February 2017 to April 2018. Two subsamples were created: (1) 45- to 69-year-old men who were age-eligible for PSA testing and (2) 18- to 44-year-old men with a family history of cancer. Age-eligible and younger deaf men with a family history of cancer are at disparity for shared decision making compared to their hearing peers. Regardless of age and PSA testing status, deaf men felt significantly less engaged in shared decision making with their health care providers compared to hearing men. Participation in shared decision making requires not only accessible communication but also cultural competency in working with deaf patients. This is critical in the shared decision-making era in maximizing the benefit of prostate cancer screening in deaf male patient population.

Genetic testing and eHealth usage among Deaf women.

In the past decade, accessible information in American Sign Language (ASL) about cancer and genetic testing is expanding on eHealth platforms, including social network sites, commercial sites, and mobile apps. Primary data on genetic testing awareness and genetic testing for BRCA 1/2 among Deaf women were gathered using HINTS-ASL survey between November 2016 and April 2018, and secondary data for hearing women were drawn from NCI's HINTS 5 Cycle 1 survey in 2017. Deaf women who had heard of DNA testing (63%) were more likely to be young adults, college graduates, and/or have a family history of cancer. Compared to hearing women, Deaf women who had heard of genetic testing were more likely to use social networking sites to read or share information about medical topics and watch health-related videos. Making eHealth platforms accessible in ASL and easy-to-understand text can help reduce knowledge gap in genetic testing, since some Deaf women may not be using genetic testing to help identify whether they are at increased risk for breast and ovarian cancer early on, before they are diagnosed with cancer.

Validity of the multidimensional fatigue symptom inventory-short form in an African-American community-based sample.

OBJECTIVES: This study examined the psychometric properties of the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) in a community-based sample of African-Americans. DESIGN: A sample of 340 African-Americans (116 men, 224 women) ranging in age from 18-81 years were recruited from the community (e.g., churches, health fairs, and beauty salons). Participants completed a brief demographic survey, the MFSI-SF and the Positive and Negative Affect Schedule. RESULTS: The structural validity of the MFSI-SF for a community-based sample of African-Americans was not supported. The five dimensions of fatigue (General, Emotional, Physical, Mental, Vigor) found for Whites in prior research were not found for African-Americans in this study. Instead, fatigue, while multidimensional for African-Americans, was best represented by a unique four-four profile in which general and emotional fatigue are collapsed into a single dimension and physical fatigue, mental fatigue, and vigor are relatively distinct. Hence, in the absence of modifications, the MFSI-SF cannot be considered to be structurally invariant across ethnic groups. A modified four-factor version of the MFSI-SF exhibited excellent internal consistency reliability and evidence supports its convergent validity. Using the modified four-factor version, gender, and age were not meaningfully associated with MFSI-SF scores. CONCLUSION: Future research should further examine whether modifications to the MFSI-SF would, as the findings suggest, improve its validity as a measure of multidimensional fatigue in African-Americans.

Health care access and breast cancer screening among Latinas along the California-Mexican border.

Latinas are more likely to exhibit late stage breast cancers at the time of diagnosis and have lower survival rates compared to white women. A contributing factor may be that Latinas have lower rates of mammography screening. This study was guided by the Behavioral Model of Health Services Use to examine factors associated with mammography screening utilization among middle-aged Latinas. An academic-community health center partnership collected data from community-based sample of 208 Latinas 40 years and older in the San Diego County who completed measures assessing psychosocial factors, health care access, and recent mammography screening. Results showed that 84.6 % had ever had a mammogram and 76.2 % of women had received a mammogram in the past 2 years. Characteristics associated with mammography screening adherence included a lower acculturation (OR 3.663) a recent physician visit in the past year (OR 6.304), and a greater confidence in filling out medical forms (OR 1.743), adjusting for covariates. Results demonstrate that an annual physical examination was the strongest predictor of recent breast cancer screening. Findings suggest that in this community, improving access to care among English-speaking Latinas and addressing health literacy issues are essential for promoting breast cancer screening utilization.

Adenoid cystic breast carcinoma: is axillary staging necessary in all cases? Results from the California Cancer Registry.

Adenoid cystic carcinoma (ACC) is an uncommon type of breast cancer. There are limited data about its epidemiology, tumor characteristics, and outcomes. Using a large, population-based data base, this study aimed to identify specific characteristics of patients with adenoid cystic breast cancer, investigate its natural history, and determine its long-term prognosis. The California Cancer Registry, a population-based registry, was reviewed from the years 1988 to 2006. The data were analyzed with relation to patient age, tumor size and stage, and overall survival. Relative cumulative actuarial survival was determined using the Berkson-Gage life table method. A total of 244 cases of invasive adenoid cystic cancer were identified in women during this time period. The patients' median age was 61.9 years. Most cases were diagnosed in non-Hispanic White women (82%, n = 200), followed by African American (6%, n = 15), Asian/Pacific-Islander (5.7%, n = 14) and Hispanic women (4.4%, n = 12). The remainder of the patients was of unknown or other ethnicity. Tumors were between 1 and 140 mm in size. At the time of diagnosis, 92% (n = 225) of patients had localized disease, 5% (n = 12) of patients had regional disease, and even fewer (n = 7) had either distant or unknown staged disease. Lymph node involvement was not present in any tumors smaller than 1.4 cm. The relative cumulative survival of patients with adenoid cystic breast carcinoma was 95.6% at 5 years and 94.9% at 10 years. ACC of the breast is a rare disease with an overall good prognosis. Knowing that this cancer usually presents as localized disease, with lymph node involvement seen only with larger tumors, can help clinicians plan the operative management of these tumors.

Individual cognitive behavioral therapy for insomnia in breast cancer survivors: a randomized controlled crossover pilot study.

PURPOSE: Estimates of insomnia in breast cancer patients are high, with reports of poor sleep lasting years after completion of cancer treatment. This randomized controlled crossover pilot study looked at the effects of individual cognitive behavioral therapy for insomnia (IND-CBT-I) on sleep in breast cancer survivors. PATIENTS AND METHODS: Twenty-one participants were randomly assigned to either a treatment group (six weekly IND-CBT-I sessions followed by six weeks of follow up) or a delayed treatment control group (no treatment for six weeks followed by six weekly IND-CBT-I sessions). Of these, 14 participants completed the pilot study (six in the treatment group and eight in the delayed treatment control group). RESULTS: Self-rated insomnia was significantly improved in the treatment group compared to the waiting period in the delayed treatment control group. The pooled pre-post-IND-CBT-I analyses revealed improvements in self-rated insomnia, sleep quality, and objective measures of sleep. CONCLUSIONS: These preliminary results suggest that IND-CBT-I is appropriate for improving sleep in breast cancer survivors. Individual therapy in a clinic or private practice may be a more practical option for this population as it is more easily accessed and readily available in an outpatient setting.

Predictors of inflammation in response to anthracycline-based chemotherapy for breast cancer.

Although chemotherapy for breast cancer can increase inflammation, few studies have examined predictors of this phenomenon. This study examined potential contributions of demographics, disease characteristics, and treatment regimens to markers of inflammation in response to chemotherapy for breast cancer. Thirty-five women with stage I-III-A breast cancer (mean age 50 years) were studied prior to cycle 1 and prior to cycle 4 of anthracycline-based chemotherapy. Circulating levels of inflammatory markers with high relevance to breast cancer were examined, including C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), Interleukin-1 receptor antagonist (IL1-RA), vascular endothelial growth factor (VEGF), soluble intercellular adhesion molecule-1 (sICAM-1), Interleukin- (IL-6), soluble P-selectin (sP-selectin), and von Willebrand factor (vWf). Chemotherapy was associated with elevations in VEGF (p < or = 0.01), sICAM-1 (p < or = 0.01), sP-selectin (p < or = 0.02) and vWf (p < or = 0.05). Multiple regression analysis controlling for age and body mass index (BMI) showed that higher post-chemotherapy levels of inflammation were consistently related to higher pre-chemotherapy levels of inflammation (ps < or =0.05) as well as to certain disease characteristics. Post-chemotherapy IL-6 levels were higher in patients who had larger tumors (p < or = 0.05) while post-chemotherapy VEGF levels were higher in patients who had smaller tumors (p < or = 0.05). Post-chemotherapy sP-selectin levels were highest in women who had received epirubicin, cytoxan, 5-fluorouracil chemotherapy (p < or = 0.01). These findings indicate that chemotherapy treatment can be associated with elevations in certain markers of inflammation, particularly markers of endothelial and platelet activation. Inflammation in response to chemotherapy is most significantly related to inflammation that existed prior to chemotherapy but also potentially to treatment regimen and to certain disease characteristics.

Malignant phyllodes tumors: a review of 752 cases.

Malignant phyllodes tumor (MPT) is a rare breast malignancy. Because of the scarcity of the disease, there are no evidence-based treatment or follow-up guidelines established. This study evaluated the survival of MPT patients to create recommendations for management. We identified 752 cases of malignant phyllodes tumors in the California Cancer Registry from the years 1988 to 2003. Relative survival was determined using Berkson-Gage life table analysis which was then compared with the relative survival of nonphyllodes breast cancer patients. For MPT patients, the relative annual survival at 1 year was 94 per cent and at 10 years was 99.6 per cent. Thus, after 10 years, these patients are no more likely to die than the general population. At 10 years, the relative cumulative survival of the MPT patients was 87.4 per cent, whereas the nonphyllodes breast cancer patients had only a 57.2 per cent relative cumulative survival. MPT patients with localized disease had a higher 10-year relative cumulative survival than those with regional disease (90.9% vs. 61.5%, P < 0.001). MPT has a good prognosis, particularly in patients with localized disease. After 10 years, MPT patients have no increased mortality relative to the general population. Clinicians should plan these patients' follow-up accordingly.

Korean American women's beliefs about breast and cervical cancer and associated symbolic meanings.

PURPOSE/OBJECTIVES: To explore Korean American women's symbolic meanings related to their breasts and cervix, to examine attitudes and beliefs about breast and cervical cancer, and to find relationships between the participants' beliefs and their cancer screening behaviors. RESEARCH APPROACH: Descriptive, qualitative analysis. SETTING: Southwestern United States. PARTICIPANTS: 33 Korean-born women at least 40 years of age. METHODOLOGIC APPROACH: In-depth, face-to-face, individual interviews were conducted in Korean. A semistructured interview guide was used to ensure comparable core content across all interviews. Transcribed and translated interviews were analyzed using descriptive content analysis. MAIN RESEARCH VARIABLES: Breast cancer, cervical cancer, cancer screening, beliefs, and Korean American women. FINDINGS: Korean American women's symbolic meaning of their breasts and cervix are closely related to their past experiences of bearing and rearing children. Negative life experiences among older Korean American women contributed to negative perceptions about cervical cancer. Having information about cancer, either correct or incorrect, and having faith in God or destiny may be barriers to obtaining screening tests. CONCLUSIONS: Korean American women's symbolic meanings regarding their breasts and cervix, as well as their beliefs about breast cancer and cervical cancer and cancer screening, are associated with their cultural and interpersonal contexts. Their beliefs or limited knowledge appear to relate to their screening behaviors. INTERPRETATION: Interventions that carefully address Korean American women's beliefs about breast cancer and cervical cancer as well as associated symbolic meanings may increase their cancer screening behaviors. Clinicians should consider Korean American women's culture-specific beliefs and representations as well as their life experiences in providing care for the population.

Breast cancer knowledge, attitudes, and screening behaviors among African American women: the Black cosmetologists promoting health program.

BACKGROUND: African American women have higher rates of breast cancer mortality than their white counterparts. Studies have suggested that this is partly caused by discovery of cancer at a later stage, highlighting the importance of encouraging early detection of breast cancer in this population. To guide the creation of a breast cancer education intervention and help focus other health educators' and clinicians' health promotion efforts, this study explored whether a cohort of African American women living in San Diego would demonstrate the possession of adequate baseline knowledge about breast cancer screening and adherence to widely recommended screening guidelines. METHODS: African American women (N = 1,055) from San Diego, California participated in a beauty salon-based survey about breast cancer knowledge, attitudes, and screening practices. Women's ages ranged from 20 to 94 years, with average age of 42.20 (SD = 13.53) years. Thirty-four percent reported completing college and/or some graduate school training, and 52% reported having some college or post high school formal training. Seventy-five percent of the sample reported working outside their home. Participating cosmetologists and their salons were recruited to the study through word-of-mouth referral by highly respected African American community leaders. RESULTS: Salon clients reported low rates of adherence to recommended breast cancer screening guidelines. Of the 1,055 participants, 31% reporting performing breast self-exam every month. Of those participants 40 and older, 57% reported having had a clinical breast exam and 43% reported having had a mammogram in the past year. Knowledge of breast cancer was associated with adherence to screening guidelines. While women recognized the serious health threat that breast cancer poses and that early detection of breast cancer is important, only 30% of women reported feeling well informed about the disease. Many participants demonstrated a lack of basic knowledge about breast cancer. The Health Belief Model postulates that access to such information is an essential element in the progression toward engaging in screening behaviors. CONCLUSION: Data from this study reflect a continuing need for increased breast cancer education for African American women. In light of the considerable mainstream information available related to breast cancer, these data reinforce the need for more breast cancer education programs that are clearly intended to attract the attention of African American women.

Early cancer detection among rural and urban Californians.

BACKGROUND: Since the stage of cancer detection generally predicts future mortality rates, a key cancer control strategy is to increase the proportion of cancers found in the early stage. This study compared stage of detection for members of rural and urban communities to determine whether disparities were present. METHODS: The California Cancer Registry (CCR), a total population based cancer registry, was used to examine the proportion of early stage presentation for patients with breast, melanoma, and colon cancer from 1988 to 2003. Cancer stage at time of detection for these cancers was compared for rural and urban areas. RESULTS: In patients with breast cancer, there were significantly more patients presenting at early stage in 2003 compared to 1988, but no difference in the percentage of patients presenting with early stage disease between rural and urban dwellers. There were no differences in incidence in early stage cancer incidence between these groups for melanoma patients, as well. In colorectal cancer in 1988, significantly more patients presented with early stage disease in the urban areas (42% vs 34%, p < 0.02). However, over time the rural patients were diagnosed with early stage disease with the same frequency in 2003 as 1988. CONCLUSION: This analysis demonstrates that people in rural and urban areas have their breast, melanoma or colorectal cancers diagnosed at similar stages. Health care administrators may take this information into account in future strategic planning.

Factors of breast cancer screening among Korean immigrants in the United States.

The purpose of this paper is to assess breast cancer screening rates and explore factors related to all three measures of breast cancer screening, mammography, clinical breast examination (CBE), and breast self-examination (BSE), among Korean immigrants in the United States. A telephone survey was conducted with 189 Korean women aged 40 and older in Cook County, Illinois. Of this group, 78% had had a mammogram at some point, and 38.6% had had one within the previous year. Fifty-three percent had had a CBE, while 26.1% had had one within the previous year. Whereas 58.1% had examined their breasts before, 46.3% did monthly BSE. Korean women's breast cancer screening rates are improving even though the rates are still lower than screening rates in the United States. Having a regular check-up and being married were strongly related to all three measures of cancer screening. Further in-depth research is suggested to understand KA women's perspectives on having access to care.

Correspondence between daily and weekly fatigue reports in breast cancer survivors.

Fatigue is a contributor to decreased quality of life and one of the most common symptoms reported by cancer survivors. Most assessment of fatigue has been retrospective and/or unidimensional. Single-item visual analogue scale ratings are commonly used, despite arguments that fatigue is better conceptualized as multidimensional. The relationships of daily to weekly ratings of fatigue, or of unidimensional to multidimensional assessments, have not been explored. Twenty-five breast cancer survivors provided daily ratings of fatigue and completed the Multidimensional Fatigue Symptom Inventory-Short Form weekly for one month. Using hierarchical linear modeling, stronger relationships of weekly ratings to average and peak rather than most recent daily ratings were found. Visual analogue scale ratings shared more variance with the General Fatigue subscale than with the other four fatigue dimensions measured. Findings suggest that different information is captured by daily versus weekly reports, and that although visual analogue scale ratings can provide a quick assessment of general fatigue, they do not capture other important dimensions.

The effects of standard anthracycline-based chemotherapy on soluble ICAM-1 and vascular endothelial growth factor levels in breast cancer.

PURPOSE: The circulating soluble form of intercellular adhesion molecule-1 (sICAM-1) and vascular endothelial growth factor (VEGF) are elevated in women with breast cancer and associated with tumor progression and poor prognosis. This study examined the effects of anthracycline-based chemotherapy on plasma sICAM-1 and VEGF, as well as soluble P-selectin, von Willebrand factor, and interleukin-6 levels. EXPERIMENTAL DESIGN: Twenty-six women diagnosed with stage I-IIIA breast cancer (mean age, 48.4 +/- 10.4 years; range, 34-79 years) were studied before (week 1) and at weeks 2 and 3 of cycles 1 and 4 of chemotherapy. RESULTS: The initial effect of chemotherapy was to reduce sICAM-1 levels; compared with pretreatment, sICAM-1 levels were decreased at week 2 of both cycles (P values < 0.01). sICAM-1 levels were elevated, however, at the start of cycle 4 as compared with pretreatment (P < 0.01). Chemotherapy led to an increase in sICAM-1 levels in node-positive but not node-negative patients (P < 0.01). VEGF levels were decreased at week 2 of cycle 4 (P = 0.001) and remained so at week 3. Similar to sICAM-1, VEGF levels were elevated at the start of cycle 4 as compared with pretreatment (P < 0.006). Soluble P-selectin levels decreased during week 2 of cycle 4 (P = 0.026). Neither interleukin-6 or von Willebrand factor were significantly changed in response to chemotherapy. CONCLUSIONS: The findings support prior studies suggesting that sICAM-1 levels derive from sources other than endothelial cells. In addition, whereas the more immediate effect of chemotherapy is to reduce sICAM-1 and VEGF, continued treatment may lead to significant elevations.
