The impact of mastectomy, breast-conserving treatment and immediate breast reconstructions on the quality of life of Chinese women

Kin Wah Fung; Yvonne Lau; A Or; Andrew Wai Chun Yip

Background: The psychosocial impact of breast surgery has been extensively studied in the Western population. There is a relative paucity of comparable data in Oriental women who are increasingly affected by cancer of the breast. The present study investigates the effects that different types of breast surgery have on the quality of life of Chinese women.

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.

Help-seeking patterns in Chinese women with symptoms of breast disease: a qualitative study

BACKGROUND Prompt utilization of health services on detecting breast symptoms can improve breast cancer (BC) survival. Little is known about Chinese womens help-seeking behaviour. Our aim was to determine patterns of self-referral among Hong Kong Chinese women with self-detected breast symptoms. METHODS We recruited 37 women awaiting their first consultation at public hospitals for breast symptoms. Interviews were transcribed and analysed based on the grounded theory approaches. RESULTS A two-stage help-seeking model provided the best interpretation of the data. Symptom recognition was triggered by symptom interpretation, symptom progression and social messages. Painful lumps were seen as symptomatic, but atypical symptoms were often dismissed as benign as they responded to dietary change. Symptom intensification and discussions with someone who had faced BC prompted consultation. Service utilization involved fear of consequences, confirmation need, symptom distress, lay referral, media prompts and opportunistic presentation. Fearing cancer as incurable delayed consultation. Utilization barriers included cost, uncertainty about referral pathways, competing priorities and embarrassment. CONCLUSIONS Atypical and painless presentation was more common among women delaying presentation. Barriers included cost, access, time and embarrassment. Education should emphasize atypical symptoms, the high-cure rate and the need for early presentation. Reduced cost and improved access to clinics would enhance early consultation.

Waiting to see the doctor: understanding appraisal and utilization components of consultation delay for new breast symptoms in Chinese women

Wylie W. Y. Li; Wendy Wing Tak Lam; J Wong; April Chiu; Miranda Chan; A Or; Ava Kwong; Dacita Suen; Sharon W. W. Chan

Delayed consultation for potential cancer symptoms influences treatment outcomes and remains problematic. Delay components (Appraisal versus Utilization) and respective associations are poorly understood.

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

Angel H. Y. Au; Wendy Wing Tak Lam; Miranda C.M. Chan; A Or; Ava Kwong; Dacita Suen; Annie L. Wong; Ilona Juraskova; Teresa W.T. Wong

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.

Background: How breast cancer surgery affects social adjustment among Chinese women is unknown, as are factors predicting such adjustment.

Communicative characteristics of interactions between surgeons and Chinese women with breast cancer in oncology consultation: a conversation analysis

Sungwon Yoon; Miranda Chan; Wai Ka Hung; Marcus Ying; A Or; Wendy Wt Lam

While previous studies have analysed features of interaction in cancer consultations using observational coding frames, relatively little attention is being given to how actual interactions are sequentially organized and achieved by participants in the course of talk‐in‐interaction. Research into the interactional practices in consultations, which involves Chinese patients, is largely absent.
