Discussion of Emotions Among Newly Diagnosed Non-Hispanic White and Chinese American Patients With Breast Cancer and Their Oncologists.

This qualitative study analyzed how Chinese American (CA) and non-Hispanic White (NHW) breast cancer patients and their oncologists communicated about patients' emotional concerns. Data included twenty-four recordings of clinical encounters between oncologists and four CA and eight NHW women with a new breast cancer diagnosis between 2013 and 2015. Using an interactional sociolinguistics approach to discourse analysis, we examined how CA and NHW patients and their oncologists initiated conversations about patients' emotions. We also categorized oncologists' responses by whether oncologists turned toward, turned away, or remained neutral to patients' emotions. When bringing up emotions with oncologists, NHW patients brought up social and personal life topics, whereas CA patients only brought up biomedical topics. We also observed that oncologists initiated discussions about emotions with only English-speaking patients of both racial groups. There were no observed differences in how oncologists remained neutral to or turned away from both CA and NHW patients' emotional expressions. When oncologists turned away from patients' emotions, they did so to solve administrative or biomedical problems. In conclusion, the findings suggest that CA patients' racial backgrounds and the language spoken during the encounters may influence how patients and oncologists initiate discussion about patients' emotions. Furthermore, the findings suggest that oncologists remain neutral and turn away from CA and NHW patients' emotions in similar ways. This study provides preliminary data for more comprehensive investigations of Asian American cancer patients' actual communication with their providers regarding emotions and treatment decisions to facilitate patient-provider communication quality.

Patient COUNTS: A pilot navigation program for Asian American cancer patients.

Many Asian American cancer patients face barriers to cancer care but little is known about their navigational needs. We designed and implemented a pilot study to provide culturally- and linguistically-appropriate navigation for Asian American cancer patients. We recruited Asian American adults age 21+ years, who spoke English, Cantonese, Mandarin, or Vietnamese, with newly diagnosed, stage I-III colorectal, liver, or lung cancer in the Northern California Bay Area. Participants were assigned a language-concordant patient navigator, who provided support and resources over 6 months. Surveys were administered at baseline, 3-, and 6-months to assess sociodemographic characteristics, healthcare access, quality of life (FACT-G), and cancer care needs. Participants' mean age was 65 years (range 38-81); 62% were men, 67% spoke Chinese, and 75% reported limited English proficiency. Forty-two percent of participants had lung, 38% colorectal, and 21% liver cancer. Of 24 participants who enrolled, 67% completed the program and 75% completed standard of care cancer treatment. The average total FACT-G score was 72.6 (SD 17) at baseline, 68.0 (SD 20) at 3 months, and 69.9 (SD 22) at 6 months. All participants reported that the program was culturally appropriate and would recommend it. Asian American cancer patients in a patient navigation program reported lower quality of life compared to the general adult cancer population. Even with navigation, 75% of participants reported completing standard of care treatment. While participants were satisfied with the program, more research is needed to address the quality of cancer care Asian American cancer patients receive.

Health disparity viewed from public historic cancer mortality data in the US: Advocacy for gastrointestinal cancers, for tailored prevention measures, and for inter-agency population data harmonization.

152 Background: We searched public datasets released by CDC to answer the question ”Can we have a bird’s-eye view of health disparity in cancer care in the US?” By looking into historic data, we hope to identify not only health disparity reflected by the different cancer mortality rates for major cancer types, but also signs of missing data. Methods: We analyzed 2016-2020 US Cancer Statistics (USCS) cancer burden data to assess cancer disparity as reflected by rates of death in different races or ethnicities. Since the 2022 AACR report on cancer in Asian Americans raised concerns, we then looked into the “Single Race 15” grouping for the underlying cause-of-death data in WONDER@CDC to count liver cancer deaths (ICD10: C22) 2018-2021 among 6 Asian minority groups with population data from 2021 Census ACS data. 2020 GLOBOCAN estimated liver cancer mortality data were also compared. With anecdotal stories suggesting immigrants may seek end-of-life care in the birth country to access culture-concordant services, we looked into how cancer deaths abroad was reported. Results: Gastrointestinal (GI) cancers emerged as an area of cancer health disparity from USCS data. 5 GI cancers (colon and rectum, pancreas, liver and bile duct, stomach, and esophagus) contributed to 1/4 of US cancer deaths, and cancers in the pancreas, liver and bile duct, and esophagus still have poor outcomes. Black non-hispanic Americans are more likely to die from cancers of colon/rectum or pancreas. All minority races or ethnicities are more likely to die from cancers in liver and bile duct, or stomach than white non-Hispanic Americans. Cancers in colon and rectum, liver and bile duct, or stomach also cause high numbers of death in US under-50 population. Liver cancer mortality of US East Asian alone groups shown in the table were lower than GLOBOCAN estimated ASR of 16.1, with the greatest discrepancy in the Chinese (9.1 vs 17.2). Difference between the Vietnamese and Asian Indians may reflect that liver cancer is #1 cause of death in Vietnam, or HepB infection is low in India. Census data excluded expat US citizens, and consulate reports of death abroad have neither cause of death nor race/ethnicity data. Conclusions: We identified gastrointestinal cancers as a focus for cancer health disparity advocacy. Divergent risks for liver cancer in Asian Americans call for tailored prevention measures. Cross-agency death abroad data harmonisation to include race/ethnicity information will complete views of cancer mortality data in US. [Table: see text]

A bird's-eye view of disparity from public historic cancer mortality data in the US: Advocacy for gastrointestinal cancers and for inter-agency data harmonization.

e13723 Background: We searched into public datasets released by CDC to answer a question raised during an NCI Health Disparity Workshop: "Can we have a bird’s-eye view of health disparity in cancer care in the US?" By looking into the historic data reported, we hope to identify not only health disparity reflected by the different cancer mortality rates for major cancer types, but also what might be missing from the data-reporting. Methods: We analyzed 2016-2020 US Cancer Statistics (USCS) cancer burden data to assess cancer disparity as reflected by rates of death in different races or ethnicities. We then looked into the recently available “Single Race 15” grouping for the underlying cause-of-death data in WONDER@CDC to count cancer deaths 2018-2021 in California comparing cancer mortality among 7 Asian minority groups, including Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, and other Asians. We then matched census data for these Asian minority groups published by Census 2020. Results: We identified gastrointestinal (GI) cancers as an area of cancer health disparity. 5 GI cancers (colon and rectum, pancreas, liver and bile duct, stomach, and esophagus) contributed to a quarter of cancer deaths, and cancers in the pancreas, liver and bile duct, and esophagus still have very poor outcomes. Based on USCS data, Black non-Hispanic Americans are more likely to die from cancers of colon/rectum or pancreas. All minority races or ethnicities are more likely to die from cancers in liver and bile duct, or stomach than white non-Hispanic Americans. Cancers in colon and rectum, liver and bile duct, or stomach also cause high numbers of death in the under-50 US population. Since the 2022 AACR report on cancer in Asian Americans raised concerns on liver and stomach cancers, we counted cancer deaths in recent 4 years for different Asian groups in California that numbered about 7 million (alone or in combination) in 2020 Census. This includes 1.8 million Chinese, 1.7 million Filipino, 900k Asian Indian, 800k Vietnamese, 560k Korean, 470k Japanese, and other Asian ethnicities. Chinese has the highest numbers of deaths (2.8k) in 4 years from these 5 GI cancers followed by Filipino (2k), Vietnamese (1.2k), Korean (1.1k), Japanese (800), other Asians (1.1k), and Asian Indian (< 400). The lower cancer deaths in Asian Indians may be associated with their younger median age based on Census. With anecdotal stories suggesting immigrants may seek end-of-life care in their birth country to access more culture-concordant services, we looked into how cancer deaths abroad were reported. The data appeared missing. Conclusions: We identified gastrointestinal cancers as focuses for cancer health disparity advocacy. Harmonized consulate report of death abroad to include detailed race/ethnicity information will complete view of cancer mortality data in the US.

Health-related Quality of Life in Elderly Asian American and Non-Hispanic White Cancer Survivors.

The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors. We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey. Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language. The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

Patient-reported supportive care needs among Asian American cancer patients

PurposeCancer is the leading cause of death for Asian Americans. However, few studies have documented supportive care needs from the perspective of Asian American cancer patients. This study describes the needs reported by Asian American patients with colorectal, liver, or lung cancer over a 6-month period during their treatment.MethodsParticipants were recruited through the Greater Bay Area Cancer Registry and from cancer care providers in San Francisco. Participants self-identified as Asian or Asian American; were age 21 or older; spoke English, Chinese, or Vietnamese; and had stage I–III colon, rectum, liver, or lung cancer. Participants were matched with a language concordant patient navigator who provided support during a 6-month period. Needs were assessed by surveys at baseline, 3, and 6 months.ResultsAmong 24 participants, 58% were 65 years or older, 42% did not complete high school, and 75% had limited English proficiency (LEP). At baseline, the most prevalent needs were cancer information (79%), nutrition and physical activity (67%), language assistance (54%), and daily living (50%). At the 3- and 6-month follow-up surveys, there was a higher reported need for mental health resources and healthcare access among participants.ConclusionIn this pilot study of Asian American cancer patients who predominantly had LEP, participants reported many needs, with cancer information and language assistance as the most prominent. The findings highlight the importance of culturally and linguistically appropriate patient navigators in addressing supportive care needs among cancer patients with LEP.Trial registrationClinicalTrials.gov identifier: NCT03867916.

Charting a Path Towards Asian American Cancer Health Equity: A Way Forward.

On July 29, 2021, the US Food and Drug Administration’s Oncology Center of Excellence convened Conversations on Cancer. This Conversation, the first ever by the US Food and Drug Administration, focused on Asian Americans and served as the platform for this Commentary. Panelists elaborated on topics ranging from heterogeneity in Asian American demographics to racism through a path to health equity and supplemented this Commentary with literature citations. Asian Americans are the fastest-growing US race group, yet data aggregation obscures distinctions and cancer disparities within the more than 24 million Asians living in the United States with harmful impacts on communities and patients, as illustrated by breast cancer survivor Susan Shinagawa’s patient-to-advocate journey. Bigotry against Asian Americans has been pervasive since the 19th century, but especially during the COVID-19 pandemic. Asian Americans are unique as the first US population to experience cancer as the leading cause of death. Asian Americans are disproportionately affected by cancers because of infectious origins and have the highest rates of lung cancer among never-smoking women. The infinitesimal proportion of the National Institutes of Health’s budget compared with experiencing the highest percentage increases of any US racial population more than 3 decades highlights the dearth of focused research among Asian Americans. Recognizing the heterogeneity of Asian Americans and that disaggregated data are critical for accurately characterizing distinct ethnic groups, focusing on the impact of racism and COVID-19 on cancer disparities, and focusing and prioritizing funding resources are necessary steps forward for achieving health equity for Asian Americans.

Abstract PO-032: Cancer supportive care needs and resource use among Asian American cancer patients: Preliminary findings from a pilot patient navigation intervention, “Patient COUNTS”

Abstract Background: Cancer is the leading cause of death for Asian Americans. Patient navigation has shown benefits in enhancing cancer treatment outcomes and quality of life. Navigational needs in accessing cancer supportive care among Asian American cancer patients and how to address such needs, however, remain understudied. Asian Americans face unique language and cultural barriers in cancer care. We designed a culturally and linguistically-tailored pilot patient navigation intervention, Patient COUNTS, to better understand and address the needs of Asian American cancer patients. Objective: To examine cancer supportive care needs and resource use among patients, who participated in a pilot study that aimed to provide culturally and linguistically-tailored navigation for Asian American cancer patients. Methods: We recruited Asian American adults diagnosed with stage I-III colorectal, liver, or lung cancer from the Greater Bay Area Cancer Registry and San Francisco hospitals. Participants spoke English, Chinese, or Vietnamese and had not completed treatment. Participants were assigned a language-concordant patient navigator, who provided support for six months. This study describes participants' cancer supportive care needs and resource use from telephone and self-administered surveys collected at baseline, three, and six months. Participants included 24 Asian Americans with cancer who completed the baseline survey, with 18 (75%) who completed at least one of the follow-up surveys. Results: Of the study sample (n=24), 63% were men, 55% were 65 years or older, and 42% did not complete high school. A majority (75%) spoke limited English; participants' preferred language included Cantonese/Mandarin (61%), Vietnamese (26%) and English (13%). Most participants had stage I (54%) or III (42%) cancer of the lung (42%), colon (37%), or liver (21%). Across the three surveys, the most frequently reported types of needs by the 24 participants were: cancer information (83%), language translation (54%), basic resources such as financial, transportation, legal, housing, and food access resources (50%), access to healthcare (42%), and mental health (33%). Among the 18 participants who completed the three- or six-month surveys, 90% reported using one or more resources that navigators directed them to. Specifically, of the 18 patients, the most frequently used resources included healthcare (77%), basic needs (67%), language translation (56%), and mental health (28%). Conclusions: The Asian American cancer patients enrolled in Patient COUNTS, a pilot patient navigation program, had a variety of cancer supportive care needs. Findings provided preliminary support of Patient COUNTS as a promising approach to assess cancer supportive care needs and assist navigation of resources among Asian American cancer patients. These findings will inform future interventions to improve the care that Asian American cancer patients receive.

Cancer Mortality in U.S.-Born versus Foreign-Born Asian American Groups (2008-2017).

Asian Americans (AA) are the fastest growing ethnic group in the United States with high proportions of immigrants. Nativity is important as cancer risk factors vary by country. We sought to understand differences in cancer mortality among AAs by nativity (foreign-born vs. U.S.-born). Ninety-eight thousand eight hundred and twenty-six AA (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese) decedents with cancer-related deaths from U.S. death certificates (2008-2017) were analyzed. Thirteen cancers that contribute significantly to Asian-American cancer mortality were selected and categorized by etiology: tobacco-related, screen-detected, diet-/obesity-related, and infection-related. Ten-year age-adjusted mortality rates [AAMR; 95% confidence interval (CI); per 100,00] and standardized mortality ratios (SMR; 95% CI) using foreign-born as the reference group were calculated. Overall, foreign-born AAs had higher mortality rates than U.S.-born. Japanese U.S.-born males had the highest tobacco-related mortality rates [foreign-born AAMR: 43.02 (38.72, 47.31); U.S.-born AAMR: 55.38 (53.05, 57.72)]. Screen-detected death rates were higher for foreign-born than U.S.-born, except for among Japanese males [SMR 1.28 (1.21-1.35)]. Diet-/obesity-related AAMRs were higher among females than males and highest among foreign-born females. Foreign-born males and females had higher infection-related AAMRs than U.S.-born; the highest rates were foreign-born males-Korean [AAMR 41.54 (39.54, 43.53)] and Vietnamese [AAMR 41.39 (39.68, 43.09)]. We observed substantial heterogeneity in mortality rates across AA groups and by nativity. Contrary to the Healthy Immigrant Effect, most foreign-born Asians were dying at higher rates than U.S.-born AAs. Disaggregated analysis of AA cancers, targeted and culturally tailored cancer screening, and treatments for infections among foreign-born Asians is critical for cancer prevention efforts.

Cytochrome P450-2D6: A novel biomarker in liver cancer health disparity.

Liver cancer morbidity and mortality rates differ among ethnic groups. In the United States, the burden of liver cancer in Asian Americans (AS) is higher compared to Caucasian Americans (CA). Research on liver cancer health disparities has mainly focused on environmental and socioeconomic factors yet has ignored the genotypic differences among various racial/ethnic groups. This lack of molecular level understanding has hindered the development of personalized medical approaches for liver cancer treatment. To understand the genetic heterogeneity of liver cancer between AS and CA, we performed a systematic analysis of RNA-seq data of AS and CA patients from The Cancer Genome Atlas (TCGA). We used four differential gene expression analysis packages; DESeq2, limma, edgeR, and Superdelta2, to identify the differentially expressed genes. Our analysis identified cytochrome P450-2D6 enzyme (CYP2D6) as the gene with the greatest differential expression with higher levels in AS compared to CA. To scrutinize the underlying mechanism of CYP2D6, Ingenuity Pathway Analysis (IPA) and Cytoscape were conducted and found hepatocyte nuclear factor-4α (HNF4A) and interleukin-6 (IL6) in direct association with CYP2D6. IL6 is downregulated in AS compared to CA, while HNF4A is not significantly different. Herein, we report that CYP2D6 may serve as a putative biomarker in liver cancer health disparities. Its negative association with IL6 proclaims an intricate relationship between CYP2D6 and inflammation in the ethnic differences seen in AS and CA liver cancer patients. The goal of the present study was to understand how genetic factors may contribute to the interethnic variability of liver cancer prevalence and outcomes in AS and CA patients. Identifying ethnic-specific genes may help ameliorate detection, diagnosis, surveillance, and treatments of liver cancer, as well as reduce disease-related incidence and mortality rates in the vulnerable population.

Abstract C017: The Patient COUNTS Study: Patient Cancer OUtreach, Navigation, Technology, and Support

Abstract Background: While cancer is the most common cause of death for Asian Americans, many Asian American cancer patients do not receive appropriate treatment nor supportive care. The Patient COUNTS project aims to provide these patients and their caregivers with accessible, culturally-relevant, and linguistically-appropriate navigation resources that utilize technology to reduce disparities and improve quality of life. Methods: With feedback from a Patient Advisory Council and focus groups with cancer patients and caregivers, we developed a patient navigation program for Asian Americans that is currently being pilot tested with patients in Northern California. We are also developing an online patient portal that will enable newly diagnosed colorectal, liver, and lung cancer patients to access appropriate resources and virtual navigation. The portal and navigation will be available in English, Chinese (Cantonese/Mandarin), and Vietnamese, with ability to collect patient-generated health data (e.g., quality of life) and provide tailored resources and navigation. Results: We conducted 4 focus groups and 3 individual interviews with 17 participants in 4 languages (English, Mandarin, Cantonese, or Vietnamese). Key emerging themes include: 1) information unawareness or overload; 2) emotional support; 3) navigation needs; and 4) resource access. Participants with limited English proficiency often did not know to ask or what to ask for regarding their diagnosis or treatment. Some, however, were confused and overwhelmed by the amount of information from many sources. Receiving encouragement to fight cancer was described as crucial in their cancer care; family, friends, doctors, nurses or hospital staff were the primary sources of such emotional support. Although most participants were unfamiliar with navigation, they thought it was very desirable once an explanation was provided. Participants wanted information on symptoms and side effects management. They recommended providing information on sensitive topics (e.g., stigma, dying) only when asked by the patient. Access to information in both their native language and English are important for their comprehensive and communication with others. For participants with end-stage disease, information on palliative care and clinical trials should be provided. These findings guided the development of our patient navigation program to provide information on cancer, treatment, living with cancer, emotional well-being, resources (access to health care, financial, transportation, housing, food and nutrition, child/adult care). Conclusions: Our formative research found significant needs among Asian American cancer patients and suggestions for how to address those needs. Implementing the in-person pilot and online portal will enable us to identify key elements of an effective, sustainable, and disseminable navigation program for Asian American cancer patients and their caregivers.

Emerging genomic biomarkers for improving kidney, prostate, and bladder cancer health disparities outcomes.

Recent advances in genomic and genetic technologies have facilitated better health outcomes for urologic cancer patients. Genomic and genetic heterogeneity may contribute to differences in tumor biology and urologic cancer burden across various populations. To examine how emerging genomic and genetic biomarkers, self-reported race, and ancestry-informative markers are associated with kidney, prostate, and bladder cancer outcomes. Genomic and genetic alterations found in African American kidney cancer patients included distinct somatic mutations, somatic copy number alterations, chromosomal instability, germ-line risk alleles, and germ-line genetic variants. These changes correlated with improved risk prediction, prognosis, and survival; and a predicted decrease in response to targeted therapies. SNP risk alleles and ancestry-informative markers were associated with improved risk prediction in prostate cancer patients of both African and European descent. AKT activation suggest differential response to AKT-targeted therapies in African American, Asian American, and Tunisian bladder cancer patients. Both self-reported race and genetic ancestry predicted urologic cancer risk prediction. Precision medicine approaches that integrate population-specific genomic and genetic information with other known urologic cancer-specific characteristics can improve outcomes and be leveraged to reduce cancer health disparities. Further investigations are necessary to identify novel genomic biomarkers with clinical utility.

Patient Portal and Navigation Program in Providing Information for Asian American Cancer Patients

Patient Portal and Navigation Program in Providing Information for Asian American Cancer Patients

The Asian American Network for Cancer Awareness, Research, and Training (AANCART)'s contributions toward reducing Asian American cancer health disparities, 2000-2017.

In 2000 and in 2 subsequent 5-year cycles, the National Cancer Institute funded grantees on a regional and national basis to address community needs for cancer awareness, research, and training. The Asian American Network for Cancer Awareness, Research and Training (AANCART) is fortunate to have been funded since 2000 to focus on mitigating cancer health disparities facing Asian Americans residing primarily in California and Hawaii. This article highlights AANCART's achievements with respect to the original specific aims and unanticipated outcomes in its most recent funded cycle. Sources included reports to the National Cancer Institute and peer-reviewed articles as well as the insights of the 3 principal investigators. All aims of the original application (infrastructure, outreach, research, and training) were attained or exceeded. Most distinctive was the completion and publication of 8 randomized controlled trials to address Asian American cancer health disparities and its nurture of 14 new and early stage investigators who have been productive in terms of research career trajectories. AANCART is contributing to mitigating Asian American cancer health disparities by catalyzing academic and community collaborations that have resulted in linguistically specific and culturally tailored educational products, scientifically rigorous interventions addressed at cancer risk factors, and nurturing new and early stage Asian American cancer investigators.

Time, trust, and transparency: Lessons learned from collecting blood biospecimens for cancer research from the Asian American community.

Biospecimens from racially diverse groups are needed to advance cancer research. The Asian American Cancer Education Study was developed to increase the number and proportion of blood biospecimen donations from Asian Americans for cancer research. The authors' targeted approach included 2 types of community engagement, in-reach (within institution to Asian American patients with cancer) and outreach (external to institution to the general Asian American community). Participants received in-language biospecimen education followed by the opportunity to donate blood biospecimens. Outreach participants donated through our community biospecimen blood drives, and in-reach participants consented to donating an extra tube of blood during their routine blood draws as a patient. Donated blood biospecimens were spun down to serum and plasma to be stored in a biorepository or were sent to the laboratory to test for cancer-related risk factors. Three hundred eighty-eight Asian Americans donated 1127 blood biospecimens for cancer research. Four hundred twenty tubes of plasma and serum are currently being stored at the cancer center's biorepository, 39 tubes have been used for cancer genomic research, and 668 tubes were used to characterize cancer-related risk factors. Building upon the past decade of the National Cancer Institute-funded Asian American Network for Cancer Awareness, Research, and Training's foundation of trust and service among Asian Americans, researchers were able to leverage relationships not only to introduce the idea of biospecimen contribution to the community but to also exceed expectations with regard to the quantity of blood biospecimens collected from Asian Americans.

Perceived Stress as a Mediator Between Social Support and Posttraumatic Growth Among Chinese American Breast Cancer Survivors.

Studies have shown that social support is positively associated with posttraumatic growth (PTG) among white cancer survivors. Whether the same relationship holds among Asian American cancer survivors and through what mechanism social support may influence PTG is unclear. This study examined the association between social support and PTG among Chinese American breast cancer survivors and proposed perceived stress as a mediator. Chinese American breast cancer survivors (n = 118) were recruited from Southern California. Participants' social support, perceived stress, and PTG were measured in a questionnaire package. Social support was associated with lower perceived stress (r= -0.34, P<.001) and higher PTG (r=0.44, P<.001). Perceived stress was negatively associated with PTG (r=-0.36, P< .001). Results from structural equation modeling supported the mediation model, with satisfactory model fit indices (χ37= 65.55, comparative fit index= 0.98, Tucker-Lewis Index = 0.97, root-mean-square error of approximation = 0.08). Both the indirect effect from social support to PTG via perceived stress (β = .07, P< .05) and the direct effect from social support and PTG (β= .40, P< .001) were statistically significant, suggesting a partial mediation effect of perceived stress between social support and PTG. The positive association between social support and Chinese American breast cancer survivors' PTG was supported. Our findings also suggested that social support may facilitate PTG through reduction of perceived stress. Interventions that help to enhance Chinese American breast cancer survivors' social support may also facilitate their PTG.
