A comparison of the characteristics, treatment and outcome after 5 years, of Australian women aged 70+ with those aged <70 years at the time of diagnosis of breast cancer.

BACKGROUND: Management of older women with breast cancer (BC) is challenging, as age-related comorbidities may limit treatment. We present 5-year follow-up data from women aged 70 years or older (70+), at the time of diagnosis of their BC, compared with younger women (<70 years). METHODS: Data is from an Australian cohort study of women with their first episode of invasive BC (Bupa study). Participants completed an enrollment questionnaire (EQ) within 12 months of diagnosis and annual follow-up questionnaires (FQ) for 5 years (FQ1-5). Data collected included details of the BC and its treatment. Psychological wellbeing was measured by the Psychological General Wellbeing Index (PGWB). RESULTS: At diagnosis, 274 (16%) women were aged 70+ and of them, 90% were aged 70-79 years. Compared with women aged <70 years, the women aged 70+ were less likely to have positive nodes, they were less likely to receive radiotherapy and chemotherapy and were more likely to have pre-existing cardiovascular morbidities. By FQ5 women aged 70+ were less likely to be taking oral adjuvant endocrine therapy (OAET) and were more likely to have died from causes other than BC. At FQ5, women 70+ reported less anxiety and better self-control. CONCLUSIONS: Women aged 70+, compared to <70 years, had less advanced disease, received radiation and chemotherapy less often, were more likely to have cardiovascular disease at the time of diagnosis, were less likely to be taking OAET at the 5-year assessment, and were more likely to die of causes other than breast cancer.

Persistent breast pain 5 years after treatment of invasive breast cancer is largely unexplained by factors associated with treatment.

PURPOSE: The aim of our study was to establish the prevalence of breast pain persisting 5 years after the initial treatment of breast cancer (BC) and the relationship between those persistent symptoms and general well-being. METHODS: The study involved women from Victoria, Australia, who had survived at least 5 years from diagnosis, remained free from recurrence or new BC and completed the fifth annual follow-up questionnaire. Analysis involved both multivariable logistic and linear regression. RESULTS: Of 1,205 women, 45 % reported breast pain which persisted for at least 3 months following initial treatment, and of these, 80 % reported pain persisting for at least 5 years. The factor contributing most to the likelihood of persistent breast pain was current lymphedema; however, a full multivariable model explained <10 % of the likelihood of breast pain persisting for 5 years. The presence of breast pain at 5 years was associated with only a modest reduction in general well-being. CONCLUSIONS: Breast pain persisting for at least 5 years after treatment for BC is common. As the pain is largely unexplained by factors associated with the characteristics of the cancer or its treatment, the contribution of patient expectations to persistent breast pain may be considerable. IMPLICATIONS FOR CANCER SURVIVORS: Where persistent pain occurs, referral for the management of pain and, where appropriate, lymphedema is warranted.

Pregnancy-associated breast cancer and pregnancy following treatment for breast cancer, in a cohort of women from Victoria, Australia, with a first diagnosis of invasive breast cancer.

BACKGROUND: This study examined pregnancy-associated breast cancer (PABC) and pregnancy following treatment for breast cancer. METHODS: We analysed data from a questionnaire-based, prospective study of women diagnosed with breast cancer. Timing of diagnosis in relation to pregnancy was self-reported in the enrolment questionnaire. Women reported subsequent pregnancies in annual follow-up questionnaires, up to at least 5 years from diagnosis. RESULTS: Women with PABC made up 3.3% of women <48 years at diagnosis and 14.3% of women aged <35 years at diagnosis. Nine of 46 (19.6%) women who were aged <40 years at diagnosis, and had either no children, or only one child, became pregnant subsequent to their diagnosis, and 8 experienced a live birth. DISCUSSION: As the number of women with PABC was small, conclusions from this study are limited. However, young women should be alert to PABC, especially in the post-partum period. Some women, with incomplete families at diagnosis, are choosing to have one or more pregnancies following treatment.

Patterns of use of oral adjuvant endocrine therapy in Australian breast cancer survivors 5 years from diagnosis.

OBJECTIVE: Oral adjuvant endocrine therapy (OAET) substantially improves the survival of women with hormone receptor-positive (HR) breast cancer. However, we reported previously that at 3 to 4 years after diagnosis, 18% of affected women are not using OAET primarily because of estrogen deficiency symptoms. The aim of this study was to determine the use of OAET in women with HR breast cancer 5 to 6 years from diagnosis. METHODS: Analysis was carried out using data from the Bupa Health Foundation's Health and Wellbeing After Breast Cancer Study, a cohort study of 1,683 women with breast cancer who were recruited in Victoria, Australia between 2004 and 2006. All women completed an enrollment questionnaire within 12 months of diagnosis and an annual follow-up questionnaire (FQ) for 5 years. The fifth FQ was completed 5.7 years from the time of diagnosis. Use of OAET was self-reported in response to a series of questions. RESULTS: A minimal exposure to OAET of at least 5 years (OAET in all six FQs) was reported by 19.7% of the women (n = 212), and another 46.7% (n = 503) received a minimal exposure of at least 4 years (OAET in five questionnaires). In total, 82.1% (n = 883) of the women would have received at least 3 years of treatment (OAET in at least four questionnaires). Only 7.8% (n = 84) reported never using OAET. CONCLUSIONS: Most women with HR breast cancer who survive at least 5 years have persisted with OAET despite the adverse effects of estrogen depletion.

Lymphedema: experience of a cohort of women with breast cancer followed for 4 years after diagnosis in Victoria, Australia.

PURPOSE: The aim of this work was to study the incidence and prevalence of self-reported lymphedema in breast cancer survivors between 2 and 4 years following diagnosis, the factors associated with the development of lymphedema and the impact of lymphedema on psychological well-being. METHODS: We assessed self-reported lymphedema in the BUPA Health Foundation Health and Wellbeing After Breast Cancer Study, a questionnaire-based study of 1,683 women newly diagnosed with their first episode of invasive breast cancer in Victoria, Australia. Psychological well-being was assessed using the Psychological General Well-being Index. RESULTS: Two years after diagnosis, nearly 20 % of women reported lymphedema and this proportion remained above 18 % 2 years later. However, self-reported lymphedema was a dynamic phenomenon, with the condition resolving in some women and others reporting onset for the first time up to 4 years from diagnosis. Lymphedema 2 years from diagnosis was positively associated with the number of nodes removed at initial surgery, although this variable only explained a small proportion of the likelihood of reporting lymphedema. The presence of lymphedema was associated with lower psychological general well-being. CONCLUSIONS: Lymphedema after breast cancer treatment frequently has a dynamic pattern and may emerge as an issue for women several years after their initial treatment. It is associated with a lower level of general well-being.

Use of imaging in surveillance of women with early stage breast cancer.

BACKGROUND: There is no evidence of benefit in terms of survival or quality of life for intensive surveillance of women with early breast cancer (BC) and current guidelines reflect this. We have examined whether Victorian women, nearly 4 years from a diagnosis of localized BC, were being managed according to these guidelines. METHODS: Participants are women in the BUPA Health Foundation Health and Wellbeing after Breast Cancer prospective cohort study. All participants completed an enrolment questionnaire within 12 months of diagnosis and then completed follow-up questionnaires every 12 months thereafter. In the third follow-up questionnaire, completed nearly 4 years from the time of diagnosis, women were asked about imaging tests they had in the previous 12 months. RESULTS: The analysis was completed on 673 women who were stage 1 at the time of diagnosis and had not reported evidence of recurrence or a new BC since diagnosis. Of the 673, 603 (89.5%) reported having had a mammogram in the previous 12 months and 319 (52.9% of those having a mammogram) reported a breast ultrasound. Seventy-one per cent of women reported no other imaging investigations in the previous 12 months. CONCLUSIONS: Our study shows that, nearly 4 years from diagnosis, Australian practitioners are generally adhering to guidelines about imaging surveillance of BC survivors. Practitioners could use the guidelines for the education of BC survivors about appropriate health surveillance.

Understanding discontinuation of oral adjuvant endocrine therapy by women with hormone receptor-positive invasive breast cancer nearly 4 years from diagnosis.

OBJECTIVE: The aim of this study was to investigate the extent of discontinuation of oral adjuvant endocrine therapy (OAET) in women nearly 4 years from the diagnosis of their first episode of invasive breast cancer and the reasons for such discontinuation. METHODS: We used a large, prospective cohort study of women who had been diagnosed with their first episode of invasive breast cancer between 2004 and 2006, recruited through a state-based cancer registry. All participants completed an enrollment questionnaire (EQ) within 12 months of diagnosis and annual follow-up questionnaires (FQs) thereafter. The data in this report were obtained from the EQ and the first three FQs. RESULTS: A total of 1,370 women with hormone receptor-positive disease completed the EQ. At the completion of the third FQ nearly 4 years from diagnosis, 1,193 women remained in the study. Use of OAET peaked by 2 years postdiagnosis. At nearly 4 years from diagnosis, 18% of the 1,193 women remaining in the study were not taking OAET. Of these women, just more than half had ceased therapy mainly owing to a range of adverse effects, predominantly estrogen deficiency symptoms, but the remainder (8% of women remaining in the study) had never used OAET. CONCLUSIONS: Our study confirms that early discontinuation of OAET due to estrogen deficiency symptoms remains an important issue despite calls for strategies to address this problem. The number of women potentially suitable for OAET but not receiving it was almost as great as the number of those who have discontinued therapy.

Changes in patterns of use of cigarettes and alcohol in women after a first diagnosis of invasive breast cancer: a cohort study of women from Victoria, Australia.

PURPOSE: Smoking and alcohol consumption after breast cancer diagnosis have received little attention. The aim of this study was to describe the change in smoking and alcohol consumption of women in the BUPA Health Foundation Health and Wellbeing After Breast Cancer Study in the first 2 years after diagnosis. METHODS: We documented cigarette and alcohol use at diagnosis in a prospective cohort study of 1,588 Australian women with invasive breast cancer in an enrolment questionnaire and again 2 years later (follow-up questionnaire, FQ1). RESULTS: Twelve percent of participants smoked at diagnosis. Nearly one third of these had quit by FQ1 and of those continuing, 1 in 4 were smoking fewer cigarettes per day. Smoking more at diagnosis was significantly associated with smoking at FQ1.Over 70% of women reported consuming alcohol in each questionnaire. The proportion of women consuming more than four alcoholic drinks per occasion at least weekly dropped between the time of diagnosis and FQ1, although by FQ1, 1 in 12 women still reported this drinking pattern. CONCLUSIONS: Smoking and alcohol consumption are important health issues for women with breast cancer. Health care providers should consider using evidence-based interventions to reduce smoking and drinking in this group.

An exploration of the dynamics and influences upon second medical opinion consultations in cancer care.

AIM: The aim of this study was to explore the dynamics within second medical opinion consultations in patients with cancer. METHODS: Semi-structured interviews were held with four oncologists and were subjected to a thematic analysis to define the broad issues. These formed the basis of a survey distributed to Australian medical oncologists. RESULTS: Overall 65 surveys were returned representing an overall response rate of 30% (10% and 63% electronic and hardcopy response rates, respectively). The dynamics in giving second medical opinions are influenced by the collegiate relationships of the doctors. Nearly two-thirds of oncologists believed that the first doctors' treatment and recommendations influenced the outcome of the second opinion, more than one-third believed the outcome was influenced by the relationship between the two doctors, and 41% believed the public nature of a second opinion was influential. In each case, these figures were more than double their assessments of patients' beliefs of these influences. Care was taken not to criticise the primary doctor. CONCLUSION: Second medical opinions provide an opportunity for oncologists to review medical care and engage in enhanced communication with patients who have additional needs. These consultations do not, however, occur in a vacuum but are influenced by the need to attend to relationships between the patient and their primary doctor and between the doctors themselves. The second medical opinion is embedded within a network of relationships and within the illness journey.

Use of complementary and alternative therapy by women in the first 2 years after diagnosis and treatment of invasive breast cancer.

OBJECTIVE: Our aim was to document patterns of consultation with alternative practitioners, use of complementary and alternative medicine (CAM) commonly used to alleviate menopausal symptoms, and lifestyle changes made by women in the first 2 years after their diagnosis with invasive breast cancer. METHODS: A total of 1,588 women in the MBF Foundation Health and Wellbeing After Breast Cancer Study completed both the enrollment questionnaire and the first follow-up questionnaire (FQ1), on average, 41 and 92 weeks after diagnosis, respectively. The Menopause Quality of Life Questionnaire and the Psychological General Wellbeing Index were included in the FQ1. Logistic regression analysis was used to examine characteristics associated with consulting a CAM practitioner or using CAMs. RESULTS: At the time of completion of the FQ1, 16.4% of women had consulted a CAM practitioner and 10.6% reported using at least one CAM commonly used to alleviate menopausal symptoms. Women who consulted a CAM practitioner and women who were using at least one CAM at the time of completion of the FQ1 were, on average, younger and more educated and had a higher Menopause Quality of Life Questionnaire score than did women who did not. Of the women, 33.6% reported having made a dietary change, and the most common lifestyle change was an increase in physical activity, which was reported by 29.0% of women. CONCLUSIONS: The frequency of use of CAMs in common usage for menopausal symptoms by women with breast cancer was lower than anticipated, increased with time from diagnosis, and is associated with more severe menopausal symptoms.

The relationship between hormone therapy use at the time of diagnosis of breast cancer and tumor characteristics.

Exposure to postmenopausal hormone therapy (HT) may affect the stage, histological type, and hormone receptor (HR) status of invasive breast cancer at the time of diagnosis. One thousand six hundred eighty-four women with newly diagnosed first invasive breast cancer were recruited to the "MBF Foundation Health and Wellbeing after Breast Cancer Study." Women using systemic HT estrogen (E) or E combined with progesterone (P) at the time of diagnosis of breast cancer were compared with those not using HT. Breast cancer tumor data were obtained from the Victorian Cancer Registry. Regression analysis was used to determine the associations between HT use or not at the time of diagnosis and tumor histology (ductal vs lobular), stage (I vs II, III, IV), HR status (ER+ or PR+ or both vs ER- or PR-). Of 1,377 women included in the analysis, 226 (16%) were using HT at the time of diagnosis. Of HT users, 20.4% had lobular breast cancer, 50% were stage I, and 85.8% had HR-positive tumors. Of non-users, 13.6% had lobular breast cancer, 48.2% were stage I, and 82.4% had HR-positive tumors. Use of systemic HT was associated with increased odds of having lobular compared with ductal breast cancer (OR = 1.75, 95% CI = 1.14-2.69, p = 0.01). There were no associations between HT use and either breast cancer stage or HR status. Women using systemic HT at the time of diagnosis were more likely to have lobular rather than ductal breast cancer compared with women not on HT.

Psychological well-being in a cohort of women with invasive breast cancer nearly 2 years after diagnosis.

PURPOSE: The aim of this study was to document the psychological well-being of a group of women with invasive breast cancer (BC) on an average of nearly 2 years after their diagnosis. METHODS: Participants were women in the Medical Benefits Fund Australia Limited Foundation Health and Wellbeing after Breast Cancer Study, a cohort study of 1,684 women recruited within 12 months of their diagnosis with invasive BC, who completed their first annual follow-up questionnaire. Psychological well-being was measured using the Psychological General Well Being Index questionnaire (PGWB) in women with BC. RESULTS: The PGWB questionnaire was completed by 1,589 women on an average of 92 weeks after their BC diagnosis, of whom 46 had evidence of active disease. PGWB total scores for all age groups of the BC cohort were lower than community-based norms (p < 0.001 for age groups > or =70, 60-<70, 50-60; p = 0.002 for age group 40-<50 and p = 0.05 for age group <40). PGWB total scores for the BC cohort were positively associated with age (p < 0.001) and living with others (p < 0.01) and inversely associated with active disease (p < 0.001) and education beyond secondary school (p = 0.03). For the domain of anxiety, there was no statistically significant association with living with others but an inverse association with education beyond school. CONCLUSION: A higher level of education may be associated with increased anxiety and lower well-being. Social support is particularly important for women with BC who are known to live alone.

Second medical opinions: the views of oncology patients and their physicians.

INTRODUCTION: Second medical opinions (SMOs) are common in oncology practice, but the nature of these consultations has received relatively little attention. This study examines the views of patients with advanced cancer and their physicians of SMOs. METHOD: Parallel, concurrent surveys were developed for patients and physicians. The first was distributed to outpatients with advanced cancer-attending specialist clinics in an Australian quaternary hospital. The second survey, developed on the basis of results of exploratory interviews with medical oncologists, was distributed to medical oncologists in Australia. RESULTS: Seventeen of fifty two (33%) patients had sought a SMO, most commonly prompted by concerns around communication with their first doctor, the extreme and desperate nature of their medical condition and the need for reassurance. Most (94%) patients found the SMO helpful, with satisfaction related to improved communication and reassurance. Patients were concerned that seeking a second medical opinion may affect their relationship with their primary doctor. Most physicians (82%) reported seeing between one and five SMO per month, with patients being motivated by the need for additional information and reassurance. Physicians regarded SMO patients as having greater information needs (84%), greater psychosocial needs (58%) and requiring more of the physician's time and energy (77%) than other patients. CONCLUSION: SMOs are common in cancer care with most patients motivated by the need for improved communication, additional information and reassurance. Physicians identify patients who seek SMOs as having additional psychosocial needs compared with other oncology patients.

Evaluation of the exposure equivalence of oral versus intravenous temozolomide.

PURPOSE: Oral temozolomide is approved in many countries for malignant glioma and for melanoma in some countries outside the USA. This study evaluated the exposure equivalence and safety of temozolomide by intravenous infusion and oral administration. METHODS: Subjects with primary central nervous system malignancies (excluding central nervous system lymphoma) received 200 mg/m(2) of oral temozolomide on days 1, 2 and 5. On days 3 and 4, subjects received 150 mg/m(2) temozolomide either as a 90-min intravenous infusion on one day or by oral administration on an alternate day. RESULTS: Ratio of log-transformed means (intravenous:oral) of area under the concentration-time curve and maximum concentration of drug after dosing for temozolomide and 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC) met exposure equivalence criteria (90% confidence interval = 0.8-1.25). Treatment-emergent adverse events were consistent with those reported previously in subjects with recurrent glioma treated with oral temozolomide, except for mostly mild and transient injection site reactions with intravenous administration. CONCLUSIONS: This study demonstrated an exposure equivalence of a 90-min intravenous infusion of temozolomide and an equivalent oral dose.

Patients' views on decision making in advanced cancer.

OBJECTIVE: To explore patients' understanding of decision making in the treatment of advanced cancer and to determine the factors they believe important to these processes in their care. METHODS: Surveys were distributed to consecutive outpatients with advanced malignancy attending a comprehensive cancer treatment center. RESULTS: Patients believed that the medical condition (94%), their doctors' experience (81%), and the medical literature (73%) are the most important factors for decisions made in their care. They also value their relationship with the doctor (63%) and their own (the patients') values (63%), and just over a third considered their family's values and the doctors' personality important. Most did not believe the doctors' values should influence decisions made. They were mindful of the uncertainty involved in decisions in the setting of advanced cancer. SIGNIFICANCE OF RESULTS: Overall, patients were satisfied with the decision-making processes and they understood and highly regarded the incorporation of factors, other than their medical condition, in their care.

The relationship between knowledge of family history and cancer characteristics at diagnosis in women newly-diagnosed with invasive breast cancer.

AIM: To document the prevalence of family history of breast cancer (BC) amongst women newly-diagnosed with invasive BC and to explore the relationship between family history and cancer size and stage. METHODS: A cross-sectional analysis was conducted on baseline questionnaire data from a cohort study of 1,684 women diagnosed with invasive BC within the previous 12 months and recruited between 2004 and 2006 in Victoria, Australia. RESULTS: Women with affected first degree relative(s) were more likely to have a smaller BC (odds ratio for

Lack of knowledge of hormone receptor status and use of endocrine therapy in invasive breast cancer.

OBJECTIVE: The aim of this study was to investigate the level of understanding in women with newly diagnosed invasive breast cancer of the key clinical features of their disease that are important determinants in treatment decision making. METHODS: The 1684 women aged between 26 and 88 years at diagnosis enrolled in a 5-year cohort study were asked by questionnaire about their estrogen receptor (ER) and progesterone receptor (PR) status and about their past or current treatment with adjuvant endocrine therapy. Information was linked with their ER and PR status determined from the histopathology report. Logistic regression analysis was used to explore the relationship between age and education status and the likelihood of being able to correctly report hormone receptor status, as well as the relationship between the likelihood of receiving adjuvant endocrine therapy and knowledge of hormone receptor status in women who were ER or PR positive. RESULTS: Not being able to correctly report hormone receptor status was associated with being older and having a lower level of education. Of women who were ER positive or PR positive or both and were at least 40 weeks from diagnosis, having received some form of endocrine therapy was significantly associated with self-identification as being ER or PR positive (OR=1.82, 95% CI 1.24-2.68, p=0.002), even when age was taken into account. CONCLUSIONS: That self-knowledge of hormone receptor status was independently associated with likelihood of receiving endocrine therapy suggests that the methods of helping women understand the nature of their breast cancer are worthy of review.

Incidence of malignancies in heart and/or lung transplant recipients: a single-institution experience.

BACKGROUND: The purpose of this study was to determine the incidence and type of malignancies in heart and/or lung transplant recipients at a single institution in Victoria, Australia, and to compare these findings with the non-transplant general Victorian population. METHODS: Recipients of heart and/or lung transplants at the Alfred Hospital between February 1989 and January 2004 were cross-referenced with the Victorian Cancer Registry. The medical records of all patients with a cancer diagnosis by January 1, 2005 were reviewed. Data were collected on baseline demographics, including cancer type, stage, treatment and survival. Cancer incidence was then compared with rates found in the Victorian population. RESULTS: There were 907 transplants (Tx) conducted between February 1989 and January 1, 2004 on 905 patients, which included 424 heart (HTx), 56 heart-lung (HLTx), 200 single-lung (SLTx), and 227 double-lung (DLTx) procedures. Of these patients, 606 (67%) were male and 299 (33%) were female. Mean age at transplantation was 46.4 years (range 12.6 to 70.4 years). Four hundred twenty-four (47%) deaths have occurred. Median survival for all patients after transplantation was 8.6 years. One hundred two cancers were confirmed, translating to a 7.1-fold increased incidence compared with the non-transplant population. The most common cancer diagnoses were lymphoproliferative disorders (692 per 100,000 person-years), head and neck cancer (336 per 100,000 person-years) and lung cancer (251 per 100,000 person-years). Compared with the non-transplant population this translates into a 26.2-, 21.0- and 9.3-fold increased risk for developing these cancers, respectively, after cardio-pulmonary transplantation. CONCLUSIONS: Certain malignancies are more common after heart and/or lung transplantation. The most predominant in our cohort were lymphoproliferative disorders, head and neck cancer and lung cancer.

Multiple periungual pyogenic granulomas following systemic 5-fluorouracil.

A 65-year-old man presented with a 7-month history of eight bleeding periungual lesions on both feet. The clinical diagnosis of multiple pyogenic granulomas was confirmed by histological examination. Historically, the pyogenic granulomas appeared 3 months after commencing 5-fluorouracil chemotherapy for rectal carcinoma, suggesting a possible causative relationship. Chemotherapy was ceased by the supervising oncologist. Resolution occurred after two lesions had been treated with curettage and diathermy, and the remaining lesions with occlusive dressings over Kenacomb ointment (triamcinolone acetonide 0.1%, neomycin sulphate 0.25%, gramicidin 0.025%, nystatin 100,000 U/g) topically twice daily for a period of 3 months.

Achieving equal standards in medical student education: is a national exit examination the answer?

Although it is commonly assumed that the quality of medical school education in Australia is uniformly high, there is no national process for assessing its outcomes. There is substantial variability in the content of medical school curricula, and the process of curriculum change is becoming more challenging because of intense competition for time and space in the course. A national exit examination could provide a uniform standard of assessment for all medical school graduates in Australia, as well as foreign graduates applying to work in Australia. Such an examination could assess medical school outcomes, monitor the effects of curriculum change, and provide a benchmark for new medical schools that would help medical curricula evolve to better meet society's needs.
