Predicting psychological morbidity in Chinese women after surgery for breast carcinoma

P16 Expression in Human Breast Carcinoma and its Relationship to Clinicopathological Parameters

Background

p16 is a cyclin-dependent kinase inhibitor and a cardinal regulator of the cell cycle. The relationship between p16 overexpression and poor prognosis of breast cancer has been reported in some studies. This study aimed to evaluate p16 expression in breast cancer in comparison to normal breast tissue and determine the association between p16 expression and clinicopathological parameters in breast cancer.

Materials and Methods

Paraffin blocks of 110 samples were studied. These included 40 invasive breast carcinoma (tumor group) and normal tissue adjacent to the tumor (tumor control), as well as 30 normal mammoplasty specimens (normal control). Samples were from the pathology archive of Alzahra Hospital, Isfahan, Iran, from 2016 to 2020. p16 expression was studied and compared in these three groups using the immunohistochemistry technique. Moreover, the relationship between p16 expression and age, tumor size, carcinoma subtype, tumor grade, and lymph node involvement was investigated in the tumor group. SPSS version 16 was used to analyze data.

Results

p16 expression showed a significant difference between the tumor group and the two control groups with a significantly higher expression in the tumor group. There was a significant direct relationship between the intensity of p16 expression and the number of involved lymph nodes (P < 0.001). No significant relationship was detected between p16 expression and other clinicopathological factors.

Conclusion

p16 seems to have a rather significant expression in breast cancer in comparison to normal breast parenchyma. However, among clinicopathological parameters, we found only a direct relationship between lymph node involvement and intensity of p16 expression.

Effect of patient decision aids on decisional conflict and regret associated with breast cancer surgery: a randomized controlled trial

BACKGROUND

Patients with breast cancer encounter difficulties in making surgical treatment decisions. Shared decision-making (SDM) with patient decision aids (PDAs) can minimize patients' decisional conflicts. However, the effect of PDAs in Asia remains inconclusive. This study investigated the effect of SDM assisted by PDAs on the decisional conflict of patients with breast cancer.

METHODS

In this two-group, outcome assessor-blind, randomized controlled trial, 151 patients diagnosed as having breast cancer were assigned to the PDA (SDM with PDA) group or the standard (SDM without PDA) group. Demographic and clinical variables were analyzed to identify variables affecting the treatment choice. The patients' decision-making difficulties were evaluated using the four-item SURE scale during preoperative hospitalization, and decisional conflicts were examined using the five-item Decision Regret scale and Hospital Anxiety and Depression Scale (HADS) 1 month after surgery.

RESULTS

The choice of breast conservation therapy and mastectomy did not significantly differ between the PDA and standard groups. The PDA group had a higher level of depression after making decisions (P = 0.029) than did the standard group. No significant difference in the total scores of the SURE scale and Decision Regret scale were noted between the groups.

CONCLUSION

PDAs did not assist the patients with breast cancer in making breast surgery-related decisions. Clinicians should focus on SDM grounded in evidence-based medicine with care and help patients consider their individual preferences.

A preliminary prospective study of health-related quality of life among Chinese-American breast cancer survivors

PURPOSE

This study examined the predictors of health-related quality of life (HRQOL) and changes in HRQOL over a 1-year period among Chinese-American breast cancer survivors (BCS).

METHODS

A two-wave longitudinal research design included participants from hospital-based cancer registries and community organizations in Los Angeles. Participants completed mailed questionnaires at baseline and 12-month follow-up. HRQOL was measured using the Functional Assessment of Cancer Therapy-General (FACT-G v.4). Change in HRQOL was assessed using a 7-point meaningful change score.

RESULTS

Participants were 73 Chinese-American BCS, a majority of whom were middle-aged (M = 54.6, SD = 9.2), lower income (63% < 45K), and diagnosed with stage I-II (83%) breast cancer. Regression analyses showed that multilevel contextual factors including general health perception, quality of care, life stress, and improvement in general health perception significantly predicted HRQOL at baseline and follow-up. The final model explained 72% of the variance of HRQOL. The examination of meaningful change indicated that improvement was reported by 32% (n = 22) and deterioration by 25% (n = 17); the majority indicated minimal change (43%, n = 30). Improvement was associated with increases in family communication, social support, and general health perception, while deterioration was associated with declines in social support, family communication, and general health perception.

CONCLUSION

Findings indicate that among Chinese-American BCS, HRQOL is influenced by socioecological factors such as family communication and life stress. Results suggest that cancer survivorship outcomes research may benefit from theoretical foundations that examine the broader contextual dimensions that seem to impact and predict HRQOL. Implications for research are discussed.

Polymorphisms in genes involved in breast cancer among Iranian patients

This review gives a summary of the important genetic polymorphisms in breast cancer with a focus on people in Iran. Several single nucleotide polymorphisms were considered as breast cancer susceptibility polymorphisms within genes (STK15, ERRs, ESR1, p53, SEP15, AURKA, SHBG, SRC, FAS, VEGF, XRCC1, GST, NFκB1, XPC, XRCC3, sirtuin-3, NKG2D). Cytosine-adenine repeat (IGF-I), rs3877899, G-2548A, GGC (eRF3a/GSPT1), IVS2nt-124A/G have shown an increased risk of breast cancers and a decreased risk has been observed in 4G/5G (PAI-1), rs6505162, tri-nucleotide (GCG TGFBR1). We observed that the signaling pathways and antioxidant related genes are the main molecular processes associated with breast cancer progression. Further studies on types of polymorphisms in breast cancer could validate the prognostic value of biomarkers.

Prevalence of Psychological Symptoms in Community-Dwelling Chinese American Patients with Chronic Cancer Pain

Cancer is common among older Chinese American immigrants. Psychological distress may be associated with cancer pain, yet prior studies have not examined this relationship. We conducted a secondary analysis of 514 Chinese Americans with cancer-related pain. Patients completed validated questionnaires, including the Chinese Health Questionnaire-12 (CHQ-12). Analyses evaluated associations among sociodemographics, acculturation, psychological distress, and pain variables. Most patients had low acculturation and socioeconomic levels. Overall, 51.9% of patients reported moderate-severe psychological distress, 35.8% reported worst pain intensity ≥7/10 over the previous week and 41.2% had high pain-related distress. Higher CHQ-12 scores were associated with younger age (β = -0.13); lower educational level (β = -0.12); birthplace in China (β = -0.18); lack of a caregiver (β = -0.10); higher worst pain intensity (β = 0.15); and higher pain-related distress (β = 0.28; all p < 0.05; R² = 0.23). Chinese American cancer patients with chronic pain experience high psychological distress, which is associated with pain characteristics and other social factors.

Randomized controlled trial of cognitive behavioural therapy for depressive and anxiety symptoms in Chinese women with breast cancer

Depressive and anxiety symptoms are frequently observed in breast cancer survivors. To date, few randomized controlled trials have been conducted on the efficacy of cognitive behavioural therapy (CBT) for depressive and anxiety symptoms in Chinese population. This study aims to verify the efficacy of CBT in Chinese breast cancer survivors. Women (n = 392) with breast cancer were randomly assigned to 3 groups: CBT (n = 98), self-care management (SCM, n = 98), and usual care (UC, n = 196) using the proportion 1:1:2. Women in the CBT and SCM groups received a series of nine sessions for 12 weeks, while women in the UC group received their usual medical care only. Depressive and anxiety symptoms were assessed using the Hamilton Depression Rating Scale (HAMD) and the Hamilton Anxiety Scale (HAMA) score at baseline, 2, 4, 8, 12, 16, and 24 weeks. A significant intergroup difference was found in the HAMD and HAMA scores. Women in the CBT group showed significantly less depressive and anxiety symptoms compared with women in the SCM and UC groups over time. In conclusion, this study supports the efficacy of CBT for depressive and anxiety symptoms in Chinese breast cancer survivors.

Quality of Life in Community-Dwelling Chinese American Patients with Cancer Pain

Although pain can be a powerful influence on health-related quality of life (HRQL) in cancer populations, culturally-based beliefs and behaviors may directly impact HQRL or modify the association between pain and HQRL. Studies of well-defined ethnic groups may clarify these relationships and inform culturally competent clinical practices intended to reduce illness burden. We evaluated HRQL in 121 non-English-speaking Chinese immigrants with cancer pain using the Functional Assessment of Cancer Therapy-General (FACT-G) scale. Overall, 91.2 % were born in China and 86.0 % were Cantonese-speaking; 50.8 % had no formal education (mean age = 63.2 years; 68.6 % women). Although the mean FACT-G score did not differ from U.S. population norms, most subscale scores for Chinese immigrants were lower and the score for social/family well-being was higher (all p < 0.05). Higher educational level, caregiver presence, lower psychological distress, lower pain intensity and interference, and lower symptom distress were associated with better HRQL (all p < 0.05). These findings confirm the importance of diverse influences on HQRL in ethnic Chinese cancer patients with chronic pain and suggest that this group may be distinguished from the majority population by the extent to which social/family well-being is preserved. Future studies in the growing population of Chinese Americans with cancer are needed to evaluate various aspects of social/family well-being and determine whether they modify the association between pain and HRQL.

A longitudinal analysis on pain treatment satisfaction among Chinese patients with chronic pain: predictors and association with medical adherence, disability, and quality of life

BACKGROUND

Patient satisfaction research in chronic pain treatment is scarce internationally and is nonexistent in Chinese communities like Hong Kong. This longitudinal study examined the relationships between medical adherence, pain treatment satisfaction, disability, and quality of life (QoL) in a sample of Chinese patients with chronic pain.

METHODS

A total of 178 patients with chronic pain were assessed at baseline, 3 and 6 months following baseline. Medical adherence and pain treatment satisfaction were assessed by the Participant Compliance Reporting Scale and the Pain Treatment Satisfaction Scale (PTSS), respectively. QoL, depression, pain catastrophizing, and pain-related fear were assessed using SF-12, the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D), the Pain Catastrophizing Scale, and the Tampa Scale for Kinesiophobia, respectively. Linear mixed effects models (LME) were fitted to identify predictors of pain treatment satisfaction, medical adherence, and QoL.

RESULTS

Results of univariate LME analyses showed significant quadratic time effects on four PTSS scores and significant associations between disability grade and PTSS scores (all p < 0.05). Medical adherence was not significantly associated with satisfaction regarding pain medication (model 1). Satisfaction with medication characteristics emerged as an independent predictor of medical adherence (model 2: std β = -0.11, p < 0.05) after controlling for sociodemographic and pain variables. Neither medical adherence nor pain treatment satisfaction predicted QoL outcomes (models 3 and 4).

CONCLUSIONS

Distinct trajectories in pain treatment satisfaction were displayed in the current sample of Chinese patients with different disability grading chronic pain. Within pain treatment, only medication characteristics significantly impacted patients' medical adherence.

Trajectories of Depressive Symptoms in Women Prior to and for Six Months After Breast Cancer Surgery

Depressive symptoms are common in women with breast cancer. This study evaluated how ratings of depressive symptoms changed from the time of the preoperative assessment to 6 months after surgery and investigated whether specific demographic, clinical, and symptom characteristics predicted preoperative levels of and/or characteristics of the trajectories of depressive symptoms. Characteristics that predicted higher preoperative levels of depressive symptoms included being married/partnered; receipt of adjuvant chemotherapy; more fear of metastasis; higher levels of trait anxiety, state anxiety, sleep disturbance, problems with changes in appetite; more hours per day in pain; and lower levels of attentional function. Future studies need to evaluate associations between anxiety, fears of recurrence, and uncertainty, as well as personality characteristics and depressive symptoms.

Cognitive emotion regulation strategies as predictors of depressive symptoms in women newly diagnosed with breast cancer

OBJECTIVE

This study aimed to determine the effects of cognitive emotion regulation strategies on depressive symptoms in women with breast cancer.

METHODS

Five hundred and nine women with breast cancer completed a demographic survey, the Chinese version of Cognitive Emotion Regulation Questionnaire (CERQ-C), and the Center for Epidemiological Studies Depression Scale (CES-D) at the initial assessment (T1). One month later (T2), 504 patients completed the CES-D. Patients were assigned to four groups: H-H (CES-D scores ≥16 at both timepoints), H-L (CES-D score ≥16 at T1, <16 at T2), L-H (CES-D score <16 at T1, ≥16 at T2) and L-L (CES-D scores <16 at both timepoints).

RESULTS

Over 80% patients had mild or no depressive symptoms at both timepoints. There were significant group differences in cognitive emotion regulation strategies. CERQ-C subscale scores for adaptive strategies were higher, and scores for maladaptive strategies were lower among patients in L-L and H-L groups than among those in H-H group. Hierarchical regression analyses showed that cognitive emotion regulation strategies at T1 differentiated depressive symptoms at T2, accounting for 56.5% of variance after controlling for sociodemographic and biological variables and baseline levels of depression. Greater acceptance, positive refocusing, and positive reappraisal at T1 were associated with fewer depressive symptoms at T2.

CONCLUSIONS

Cognitive emotion regulation strategies accounted for considerable variance in depressive symptom scores 1 month later. The strategies of acceptance, positive refocusing, and positive reappraisal may be beneficial for women with breast cancer. Intervention studies are needed to confirm if these associations are causal.

Reducing treatment decision conflict difficulties in breast cancer surgery: a randomized controlled trial

PURPOSE

Breast cancer (BC) decision aid (DA) randomized studies are limited to DA use in consultations among Western populations and for primary surgery. Their effectiveness beyond consultations, for reconstructive surgery and in other populations, has not been evaluated. We developed a DA administered after consultation for Chinese women deciding on BC surgery and, where relevant, immediate breast reconstruction, which was evaluated in this randomized controlled trial (RCT).

PATIENTS AND METHODS

Overall, 276 women considering BC surgery for early-stage BC were randomly assigned to receive a DA (take-home booklet) or the standard information booklet (control condition) after the initial consultation, wherein surgeons disclosed the diagnosis and discussed treatment options with patients. Using block random assignment by week, 138 women were assigned to the DA arm and 138 to the control arm. Participants completed interview-based questionnaires 1 week after consultation and then 1, 4, and 10 months after surgery. Primary outcome measures were decisional conflict, decision-making difficulties, BC knowledge 1 week after consultation, and decision regret 1 month after surgery. Secondary outcome measures were treatment decision, decision regret 4 and 10 months after surgery, and postsurgical anxiety and depression.

RESULTS

The DA group reported significantly lower decisional conflict scores 1 week after consultation (P = .016) compared with women in the control arm. Women receiving the DA had significantly lower decision regret scores 4 (P = .026) and 10 months (P = .014) after surgery and lower depression scores 10 months after surgery (P = .001).

CONCLUSION

This RCT demonstrated DAs may benefit Chinese patients in Hong Kong by reducing decisional conflict and subsequent regret and enhance clinical services for this population.

Measurement of distress in Chinese inpatients with lymphoma

PURPOSE

The aim of this study was to assess the levels and sources of distress in patients with lymphoma. This study also focused on the influence of factors of the level of distress and the cutoff score using the Distress Thermometer (DT) relative to the Hospital Anxiety and Depression Scale (HADS).

METHOD

DT and HADS were used to estimate the psychological status of 323 eligible lymphoma patients. The DT was evaluated against the HADS for its sensitivity and specificity.

RESULTS

One hundred and ninety-three (59.7%) lymphoma patients experienced overall distress on the HADS, with 137 (42.4%) experiencing anxiety and 114 (35.3%) suffering from depression. There were 199 (61.6%) and 163 (50.5%) patients with distress score ≥ 4 and ≥ 5, respectively. DT was significantly correlated with the HADS-total (T) (r=0.820, p<0.001), HADS-depression (D) (r=0.763, p<0.001), and HADS-anxiety (A) (r=0.738, p<0.001). The consistency of the DT and HADS was favorable (coherence index=0.6030, p<0.01) when the cutoff score was 5 for the DT. Referring to the cutoff of 15 on HADS, 5 on DT yielded optimal specificity (0.869, p<0.001) and sensitivity (0.756, p<0.001). In multiple logistic regression analysis, patients with 'B symptoms' were more likely to have a distress score ≥ 5 [OR=4.512, p<0.05, 95% CI 1.953-10.467].

CONCLUSION

DT is efficacious for screening for anxiety and depression in lymphoma patients.

Symptom distress associated with biopsy in women with suspect breast lesions

Purpose. To investigate symptom distress, quality of life, affective states, and inflammatory biomarkers before and after breast biopsy in women undergoing breast biopsy. Methods. A convenience sample of 47 women undergoing breast biopsy was assessed at the pre- and post-biopsy visits. The assessments included evaluation of fatigue, anxiety, depression, sleep disturbances, positive and negative affect, quality of life using validated self report measures, and a blood draw to determine markers of inflammation. Results. At the postbiopsy visit, a total of 15 participants were diagnosed with breast cancer, and 32 participants received negative biopsy result. The mean anxiety and sleep disturbances scores were in the clinically significant range for the total sample and for the biopsy positive (BC+) and biopsy negative (BC−) subgroups at both time points. For both subgroups, anxiety and sleep disturbances scores did not change significantly from pre- to post-biopsy. A subpopulation of participants in both groups reported moderate-to-severe anxiety, depression and fatigue levels at both time points. The inflammatory markers did not show consistent associations with psychosocial symptoms. Conclusions. A subset of participants in BC+ and BC− subgroups experience heightened symptom distress and negative impact on quality of life at both pre- and post-biopsy time points.

Supportive care needs in Hong Kong Chinese women confronting advanced breast cancer

BACKGROUND

Women with advanced breast cancer (ABC) are living longer, so understanding their needs becomes important. This cross-sectional study investigated the type and extent of unmet supportive care needs in Hong Kong Chinese women with advanced breast cancer.

METHODS

Face-to-face interviews were conducted among women with stage III or stage IV disease mostly awaiting chemotherapy (76%) to identify unmet needs using the Supportive Care Needs Survey Short Form, psychological morbidity using the Hospital Anxiety and Depression Scale, symptom distress using the Memorial Symptom Assessment Scale, and satisfaction with care using the Patient satisfaction questionnaire (PSQ-9).

RESULTS

About 27-72% of 198/220 (90%) women (mean age = 53.4 ± 9.74 (standard deviation) years) identified needs from the health system, information, and patient support (HSIPS) domain as the top 15 most prevalent unmet needs. 'having one member of hospital staff with whom you can talk to about all aspect of your condition, treatment, and follow-up' was most cited by 72% of the patients, with remaining unmet needs addressing mostly desire for information. Unmet need strength did not differ between women with stage III and stage IV disease, whereas women with first time diagnosis reported greater health system and information unmet needs compared with women with recurrent disease. Stepwise multiple regression analyses revealed that symptom distress was consistently positively associated with all but sexuality need domains, whereas low satisfaction with care was associated with HSIPS (β = 3.270, p < 0.001) and physical and daily living (β = 2.810, p < 0.01) domains.

DISCUSSIONS

Chinese women with ABC expressed need for continuity of care and improved information provision. High symptom distress was associated with lower levels of satisfaction with care. These unmet needs appear to reflect current care services shortcomings.

The patient-physician relationship in patients with breast cancer: influence on changes in quality of life after rehabilitation

PURPOSE

The objective of this study was to examine whether aspects of the patient-physician relationship for breast cancer patients have an influence on the change in health-related quality of life (HRQOL) after inpatient rehabilitation.

METHODS

N = 329 breast cancer patients undergoing inpatient rehabilitation in Germany were surveyed using questionnaires at the beginning of rehabilitation, end of rehabilitation, and 6 months after rehabilitation. Multiple imputations and multilevel models of change were used in the data analyses.

RESULTS

Even after comprehensive adjustment for sociodemographic, medical, psychological variables, and center effects, aspects of the physician-patient relationship were statistically and clinically relevant predictors of HRQOL after rehabilitation. Satisfaction with physician's care appears to have a rather short-term effect, but the effect of promoting patient participation can still be partially determined 6 months after rehabilitation. Other important predictors of HRQOL improvement are optimism, higher level of education, higher income, living with a partner, and the ability to work.

CONCLUSIONS

By taking into consideration the patient's communication and participation needs, physicians can contribute to an improved HRQOL after rehabilitation. The high predictive power of socioeconomic factors shows that rehabilitation care can be more effective if it accounts for the specific situation of socially disadvantaged individuals.

Meaning making: psychological adjustment to breast cancer by Chinese women

Based on a study exploring the phenomenon of coping among Hong Kong Chinese women afflicted with breast cancer, from diagnosis to completion of treatment, we report the findings on meaning making by the informants. Using the grounded theory method, we conducted 35 interviews with 24 women suffering from breast cancer. Among them, we followed and interviewed 5 women thrice, from diagnosis to 3 months after completion of treatment. We noted the evolution of reframing as the key category in the adjustment process through which the women identified meaning at different points of time in the cancer experience, to achieve different outcomes. Chinese women identified a sustaining force from minimizing social disturbance during treatment. The integration of cancer into their lives after completion of treatment was achieved through positive transformation in their philosophy of life and social relationships. Nurses should aim to understand the cancer patients' interpretation of the situation, explore personally meaningful sustaining forces, and reflect on their cancer experience.

Pain in underserved community-dwelling Chinese American cancer patients: demographic and medical correlates

BACKGROUND

Little is known about cancer pain in Chinese Americans. The objective of this study was to describe the epidemiology of pain in this population. This information is needed to identify and address unmet clinical needs for culturally relevant interventions targeting pain and its consequences.

METHODS

A consecutive sample of underserved ethnic Chinese patients in a large community-based oncology practice was screened for persistent or frequent pain. Those patients with pain completed translated instruments assessing demographics, linguistic acculturation, disease-related characteristics, and pain-related characteristics.

RESULTS

Of 312 patients screened, 178 (57.1%) reported frequent or persistent pain, 175 were eligible, and 170 participated. Most participants (85.9%) were born in China and 84.7% overall spoke Cantonese only. The most common cancers were gastrointestinal (28.2%), lung (21.8%), breast (20.6%), head and neck (12.9%), and genitourinary (4.7%); 43.5% had metastatic disease. The mean worst pain severity on a 0-10 numeric scale was 4.7 (standard deviation, 2.4), with 28.2% of patients rating their worst pain at ≥7 of 10. Although 37.6% used opioids and 47.1% used nonopioids, 45.8% reported "little" or "no" pain relief from medications. Complementary or alternative medicine therapies for cancer pain were used by 35.8%. In multiple regression analyses, worst pain was positively associated with acculturation to the English language and opioid therapy, and pain-related distress was positively associated with opioid therapy.

CONCLUSION

Pain is prevalent among community-dwelling, ethnic Chinese American cancer patients. Additional studies are needed to confirm these results and investigate the finding that higher linguistic acculturation is associated with reports of more intense pain.

Trajectories of psychological distress among Chinese women diagnosed with breast cancer

BACKGROUND

The distinct trajectories of psychological distress over the first year of the diagnosis with breast cancer (BC) and its determinants have not been explored.

METHODS

285 of 405 Chinese women receiving surgery for BC were assessed at 5-day, 1-month, 4-month, and 8-month post-surgery on measures of psychological distress, optimism, treatment decision-making (TDM) difficulties, satisfaction with treatment outcome, satisfaction with medical consultation, and physical symptom distress. Latent growth mixture modelling identified trajectories of psychological response to BC. Multinominal logistic regression compared TDM difficulties, satisfaction with treatment outcome, satisfaction with medical consultation, optimism, and physical symptom distress, by distress pattern adjusted for age, education, employment status, and stage of disease.

RESULTS

Four distinct trajectories of distress were identified, namely, resilience (66%), chronic distress (15%), recovered (12%), and delayed-recovery (7%). TDM difficulties, optimism, satisfaction with consultation, and physical symptom distress predicted distress trajectories. Psychologically resilient women had less physical symptom distress at early post-surgery compared with women with other distress patterns. Compared with the resilient group, women in the recovered or chronic distress groups experienced greater TDM difficulties, whereas women in the delayed-recovery group reported greater dissatisfaction with the initial medical consultation. Women in the chronic distress group reported greater pessimistic outlook.

CONCLUSION

Optimism and better early post-operative treatment outcomes predicted resilience to distress. Pre-operative interventions helping women to establish a realistic expectation of treatment outcome may minimize disappointment with treatment outcome and resultant distress, whereas post-operative rehabilitation should focus on symptom management.

Development and pilot-testing of a Decision Aid for use among Chinese women facing breast cancer surgery

BACKGROUND

Women choosing breast cancer surgery encounter treatment decision-making (TDM) difficulties, which can cause psychological distress. Decision Aids (DAs) may facilitate TDM, but there are no DAs designed for Chinese populations. We developed a DA for Chinese women newly diagnosed with breast cancer, for use during the initial surgical consultation.

AIMS

Conduct a pilot study to assess the DA acceptability and utility among Chinese women diagnosed with breast cancer.

METHODS

Women preferred the DA in booklet format. A booklet was developed and revised and evaluated in two consecutive pilot studies (P1 and P2). On concluding their initial diagnostic consultation, 95 and 38 Chinese women newly diagnosed with breast cancer received the draft and revised draft DA booklet, respectively. Four-day post-consultation, women had questionnaires read out to them and to which they responded assessing attitudes towards the DA and their understanding of treatment options.

RESULTS

The original DA was read/partially read by 66/22% (n = 84) of women, whilst the revised version was read/partially read by 74/16% (n = 35), including subliterate women (χ(2) = 0.76, P = 0.679). Knowledge scores varied with the extent the booklet was read (P1: F = 12.68, d.f. 2, P < 0.001; P2: F = 3.744, d.f. 2, P = 0.034). The revised, shorter version was graphically rich and resulted in improved perceived utility, [except for the 'treatment options' (χ(2) = 5.50, P = 0.019) and 'TDM guidance' (χ(2) = 8.19, P = 0.004) sections] without increasing anxiety (F = 0.689, P = 0.408; F = 3.45, P = 0.073).

CONCLUSION

The DA was perceived as acceptable and useful for most women. The DA effectiveness is currently being evaluated using a randomized controlled trial.

Distress trajectories at the first year diagnosis of breast cancer in relation to 6 years survivorship

PURPOSE

To explore how initial trajectories of distress experienced during the first year following diagnosis with early-stage breast cancer (ESBC) relate to subsequent long-term(6 years) psychosocial outcomes.

METHODS

285/303 Chinese women recruited 1-week post-surgery for predominantly ESBC were assessed for distress with the Chinese Health Questionnaire at 1, 4, and 8 months later.Latent growth mixture modeling revealed four distinct distress trajectories during the first 8 months following surgery (Lam et al., 2010). Six years later we reassessed 186 of these 285 women, comparing scores on the Hospital Anxiety and Depression Scale, Impact of Events Scale, and Chinese Social Adjustment Scale by first 8 months’ distress trajectory.

RESULTS

Distress trajectories over the first 8 months post-operatively predicted psychosocial outcomes 6 years later. Women with stable low levels of distress over the first 8 months postoperatively(resilient group) had the best 6-year psychosocial outcomes. Women who experienced chronic distress had significantly greater longer-term psychological distress, cancer-related distress, and poorer social adjustment in comparison to women in the resilient group. Women in the recovered or delayed-recovery groups were comparable to those in the resilient group, except for concerns about appearance and sexuality, and self-image.

CONCLUSION

Women with an illness trajectory characterized by chronic distress over the first 8 months post-operatively had poorest longer-term psychosocial outcomes. Clarification of determinants of chronic distress and means for early identification of at-risk women are needed.This will enable targeted optimization of interventions to prevent and manage chronic distress,improving ESBC rehabilitation efficiency.

Adaptation process and psychosocial resources of Chinese colorectal cancer patients undergoing adjuvant treatment: a qualitative analysis

OBJECTIVES

To examine how Chinese patients with colorectal cancer (CRC) dynamically adapt to diagnosis and treatment and explore how patients evolve and deploy different resources throughout the illness trajectory.

METHODS

Semi-structured interviews were conducted on a purposive sample of 16 histologically diagnosed Chinese CRC patients about to complete or who had very recently completed all treatment without recurrence. Recorded interviews were transcribed verbatim and analyzed by using grounded theory techniques.

RESULTS

Three major adaptation-related themes were identified: (1) utilization of medical resources, (2) transition of resource utilization, and (3) continuous resistance to demands. Initial prevailing fatalistic views of diagnosis associated predominantly with frequent medical surveillance and with respondents' weighting of treatment and expertise of medical professionals. As treatment progressed, there was a shift toward reliance on personal and social resources to field cancer-related demands concurrent with a gradual distancing from medical care. Upon treatment completion, fatalism re-emerged regarding disease recurrence, which, like diagnosis, was seen as not amenable to individual control, even with close adherence to medical follow-ups and dietary adjustment. Maintaining positive states of mind and good relationships with family and friends were cores strategies respondents adopted to preserve psychological well-being.

CONCLUSIONS

Maintenance and enhancement of personal and social resources throughout the CRC trajectory may have considerably more utility than traditional descriptive studies hitherto suggested. Considering personal and social resources within dynamic rather than static models could avoid the pitfall of attributing maladaptive responses to initial dispositions and socioeconomic conditions that are seemingly unalterable and enduring over time.

Optimism and physical health: a meta-analytic review

BACKGROUND

Prior research links optimism to physical health, but the strength of the association has not been systematically evaluated.

PURPOSE

The purpose of this study is to conduct a meta-analytic review to determine the strength of the association between optimism and physical health.

METHODS

The findings from 83 studies, with 108 effect sizes (ESs), were included in the analyses, using random-effects models.

RESULTS

Overall, the mean ES characterizing the relationship between optimism and physical health outcomes was 0.17, p < .001. ESs were larger for studies using subjective (versus objective) measures of physical health. Subsidiary analyses were also conducted grouping studies into those that focused solely on mortality, survival, cardiovascular outcomes, physiological markers (including immune function), immune function only, cancer outcomes, outcomes related to pregnancy, physical symptoms, or pain. In each case, optimism was a significant predictor of health outcomes or markers, all p < .001.

CONCLUSIONS

Optimism is a significant predictor of positive physical health outcomes.

A longitudinal analysis of patient satisfaction and subsequent quality of life in Hong Kong Chinese breast and nasopharyngeal cancer patients

BACKGROUND

We evaluated the longitudinal course of the relationship between patient satisfaction and quality of life (QoL) in Chinese breast and nasopharyngeal cancer patients.

METHODS

A sample of Chinese breast (n = 250) and nasopharyngeal (n = 242) cancer patients were assessed during their first outpatient visit (baseline) and at 2 follow-up interviews (FU1 and FU2). The Chinese version of the Functional Assessment of Cancer Therapy-General Scale (FACT-G (Ch)) was adopted to assess QoL. Patient satisfaction was assessed by the 9-item Chinese Patient Satisfaction Questionnaire (ChPSQ-9) and the cognitive subscale of the Medical Interview Satisfaction Scale (MISS-Cog). Linear mixed effects models were fitted to identify predictors of patient satisfaction and QoL.

RESULTS

Recurrence after baseline (std beta = 0.58; 95% CI: 0.17, 0.98; P < 0.05) was the only predictor of MISS-Cog, age (std beta = 0.01; 95% CI: 0.00, 0.02; P < 0.05) and depressed mood (std beta = 0.20; 95% CI: 0.10, 0.30; P < 0.001) of ChPSQ-9. After adjusting for sociodemographic and psychosocial variables, both ChPSQ-9 (std beta = 0.13; 95% CI: 0.07, 0.19; P < 0.001) and MISS-Cog (std beta = 0.07; 95% CI: 0.02, 0.12; P < 0.05) independently predicted FACT-G (Ch) scores.

CONCLUSIONS

These findings suggest both general emotional support and informational support are important in predicting QoL among Chinese breast and nasopharyngeal cancer patients.

Tissue array for Tp53, C-myc, CCND1 gene over-expression in different tumors

AIM: To rapidly detect molecular alterations in different malignancies and investigate the possible role of Tp53, C-myc, and CCND1 genes in development of tumors in human organs and their adjacent normal tissues, as well as the possible relation between well- and poorly-differentiated tumors.

METHODS: A tissue array consisting of seven different tumors was generated. The tissue array included 120 points of esophagus, 120 points of stomach, 80 points of rectum, 60 points of thyroid gland, 100 points of mammary gland, 80 points of liver, and 80 points of colon. Expressions of Tp53, C-myc, and CCND1 were determined by RNA in situ hybridization. 3’ terminal digoxin-labeled anti-sense single stranded oligonucleotide and locked nucleic acid modifying probe were used.

RESULTS: The expression level of Tp53 gene was higher in six different carcinoma tissue samples than in paracancerous tissue samples with the exception in colon carcinoma tissue samples (P < 0.05). The expression level of CCND1 gene was significantly different in different carcinoma tissue samples with the exception in esophagus and colon carcinoma tissue samples. The expression level of C-myc gene was different in esophagus carcinoma tissue samples (χ² = 18.495, P = 0.000), stomach carcinoma tissue samples (χ² = 23.750, P = 0.000), and thyroid gland tissue samples (χ² = 10.999, P = 0.004). The intensity of signals was also different in different carcinoma tissue samples and paracancerous tissue samples.

CONCLUSION: Over-expression of the Tp53, CCND1, and C-myc genes appears to play a role in development of human cancer by regulating the expression of mRNA. Tp53, CCND1 and C-myc genes are significantly correlated with the development of different carcinomas.

New insights in symptom assessment: the Chinese Versions of the Memorial Symptom Assessment Scale Short Form (MSAS-SF) and the Condensed MSAS (CMSAS)

There are very few symptom assessment instruments in Chinese. We present the validity and reliability of the Memorial Symptom Assessment Scale Short Form (MSAS-SF) and the Condensed Form MSAS (CMSAS) in Chinese cancer patients. The Chinese version of the 32-item MSAS-SF, a self-report measure for assessing symptom distress and frequency in cancer patients, was administered to 256 Chinese patients with colorectal cancer at a clinical oncology outpatient unit. Highly prevalent symptoms included worrying (59%), dry mouth (54%), lack of energy (54%), feeling sad (48%), feeling irritable (48%), and pain (41%). Both the MSAS-SF and CMSAS demonstrated good validity and reliability. For the MSAS-SF subscales, Cronbach alphas ranged from 0.84 to 0.91, and for CMSAS subscales, from 0.79 to 0.87. Moderate-to-high correlations of MSAS-SF and CMSAS subscales with appropriate European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 subscales (0.42-0.71, Ps<0.001) indicated acceptable convergent validity. Low correlations with the Rosenberg Self-Esteem and Optimism Scale (0.22, P<0.001) indicated divergent validity. MSAS subscales varied as expected with other Chinese scales--the Chinese Health Questionnaire (CHQ) and the Life Orientation Scale. Construct validity of both MSAS versions was demonstrated by effective differentiation between clinically distinct patient groups (Karnofsky scores <80% vs. > or =80% [P<0.001]; no active treatment vs. active treatment [P<0.002-0.034]; CHQ-12 scores < or =4 vs. CHQ-12 scores >4 [P<0.001]). The Number of Symptoms subscale correlated appropriately with the EORTC QLQ-C30 function (-0.46 to -0.60, P<0.001) and symptom scales (0.31-0.64, P<0.001). The average time to complete the MSAS-SF was six minutes. The Chinese versions of the MSAS-SF and CMSAS are valid and practical measures. Further validation is needed for Chinese patients with other cancer types and with other symptom instruments.

Alteration of cyclin D1 in Chinese patients with breast carcinoma and its correlation with Ki-67, pRb, and p53

BACKGROUND

For the female population in Asia, systematic investigation on alterations of cyclin D1 in breast carcinoma is rare, and correlation between cyclin D1 expression with clinicopathological parameters, survival rate, and other prognostic marker associated with cell cycle is unclear.

METHODS

Expression of cyclin D1 protein, Ki-67, pRb, and p53 was determined by immunohistochemistry in 18 cases of early breast carcinomas and 80 cases of invasive ductal carcinomas. Genetic alteration of cyclin D1 gene and overexpression of cyclin D1 mRNA were detected by Southern blot and RT-PCR, respectively.

RESULTS

Expression of cyclin D1 is negative in usual ductal hyperplasia (UDH) and atypical ductal hyperplasia (ADH). However, in 52.0% (51/98) of all breast carcinomas, positive expression of cyclin D1 was observed. Five-year survival rate of the patients with positive expression of cyclin D1 (52.7%) is significantly lower than the cases with negative expression of cyclin D1 (72.1%). Positive rate of cyclin D1 protein in invasive ductal carcinoma (52.5%) is slightly higher than overexpression rate (40.8%) of cyclin D1 mRNA but significantly higher than amplification rate of cyclin D1 gene (18.4%). Expression of cyclin D1 is correlated with Ki-67 expression, but not correlated with pRb and p53 expression.

CONCLUSIONS

Positive expression of cyclin D1 could serve as a poor prognostic marker for Chinese patients with breast carcinoma independent of nodal metastasis and clinical stage. Expression of cyclin D1 protein is affected more directly by overexpression of cyclin D1 mRNA rather than cyclin D1 gene amplification. The cooperation between pRb and p53 with cyclin D1 protein in the carcinogenesis of breast carcinoma is not supported by the results.

Surgical treatment preferences in Chinese-American women with early-stage breast cancer

Breast-conserving treatment (BCT) is considered preferable to radical or modified radical mastectomy (MRM) for most women diagnosed with early-stage breast cancer. Studies have found that Chinese-American women are more likely to be treated with MRM, regardless of age or stage of disease. The central question posed in this study is: what are the cultural factors that influence the selection of treatments by Chinese-American patients and the presentation of treatment options by providers? Focused group discussions, semi-structured interviews, and ethnographic observations were conducted with 69 Chinese-American women and 14 health professionals. Results indicated that (1) many Chinese-American women, regardless of age, migration status, education, and income level, expressed a preference for MRM because it was seen as safer; (2) this was primarily a communal belief that even women who had BCT felt pressure to conform to; (3) some women felt pressured into the BCT decision by their physician and/or were unhappy with their choice; (4) patient and physician bias and difficulties with translation issues and supplemental materials all led to cross-cultural miscommunication; and (5) this miscommunication was cited as a reason for (a) not completing treatment regimes or (b) drastic changes in the treatment selected.

The incidence, indications and outcome for the non-operative management of breast cancer

BACKGROUND AND OBJECTIVES

This study aimed to identify the proportion of patients with breast cancer who do not undergo primary operative treatment, to identify the reasons surgery is not performed, and to determine the outcome for this group of patients.

METHODS

Data was obtained from the Bedford Breast Cancer Registry for all non-metastatic patients presenting between January 1990 and December 2004 who were initially treated non-operatively. Robust diagnostic, therapeutic, and follow-up data on all patients was collected prospectively during this period.

RESULTS

One hundred and eighty-five out of 2110 episodes of breast cancer were treated non-operatively during this period. Sixty-eight percent of patients were unfit for surgery, 15% had inoperable tumours, and 17% refused surgical intervention. Median survival and 5-year survival rate for all non-operative patients were 3.7 years and 41.2%. Median survival for inoperable patients was 3.7 years, compared with 3.5 years for those unfit for surgery and 4.2 years for those who refused surgery. The 5-year survival rate for patients refusing surgery was 43%, compared with 61% for a matched group of patients undergoing standard surgical therapy.

CONCLUSIONS

This study provides useful data on the reasons for, and outcome of, the non-operative management of breast cancer.

Treatment decision difficulties and post-operative distress predict persistence of psychological morbidity in Chinese women following breast cancer surgery

BACKGROUND

The patterns and determinants of longer-term psychological morbidity in women following breast cancer surgery have not been described for Chinese populations.

METHODS

Chinese women were assessed at 3-days, 4-months and 8-months following breast surgery, on treatment decision-making difficulty (TDMD), satisfaction with treatment outcome (E-OI), self efficacy (GSeS), optimism (C-LOT-R), consultation satisfaction (C-MISS-R), physical symptom distress (PSD) and psychological morbidity (CHQ-12) and compared using polynomial logistic models.

RESULTS

Of 303/405 women providing complete data, 33% received chemotherapy and 26% radiotherapy. GSeS, CLOTR and TDMD scores were moderate. Though the proportion of women meeting psychological morbidity case-criteria declined from 78% (95% Confidence Interval 73-83%) at Baseline to 64% (59-69%) at 8-months, almost 50% (44-54%) of women remained distressed over the 8-month period. After adjustment for demographic and clinical factors, severity of psychological morbidity at 4-months was predicted by PSD, disappointment and higher Baseline CHQ12, and among moderate/severe cases only, greater TDMD and pessimistic outlook. At 8-months, CHQ12 scores were predicted by PSD, Baseline CHQ-12, and difficulties with TDM.

CONCLUSION

TDM difficulties, early post-surgical psychological and physical symptom distress indicate risk for prolonged distress in Chinese women following breast cancer surgery.

Quality of life and pain in Chinese lung cancer patients: Is optimism a moderator or mediator?

OBJECTIVE

To clarify if optimism exerts a primarily moderating or mediating influence on the pain-QoL association in Chinese lung cancer patients.

METHODS

About 334 Chinese lung cancer patients were interviewed at baseline during the first outpatient visit (Baseline), at 4 months after Baseline (FU1), and at 8 months after Baseline (FU2). Respondents completed the Chinese version of the FACT-G version-3 scale (FACT-G (Ch)). Optimism and pain were assessed using two 11-point self-rated items. Linear mixed effects (LME) models tested the moderating and mediating effects of optimism on QoL.

RESULTS

Optimism, pain, and QoL were most strongly correlated at FU1. LME models failed to show any moderating effect by optimism on the pain-QoL association (standardized beta = -0.049, 95% CI -0.097 to 0.001). After adjustment for age, cancer stage, and disease recurrence, a modest mediating effect was observed for optimism on the pain-QoL association over the duration of the study (standardized beta = 0.047; Sobel test z = -4.317, p < 0.001).

CONCLUSIONS

Optimism qualifies as a mediator between pain and QoL suggesting that pessimistic lung cancer patients are likely to experience greater QoL decrements in response to pain in the early post-diagnostic period. Effective pain control may be enhanced by inclusion of interventions that facilitate optimistic perspectives in patients. This study lends further support to the view that lung cancer patients' psychological needs are important in both pain control and QoL.
