Predictors of Quality of Life Decline in Patients with Oligometastases treated with Stereotactic Ablative Radiotherapy: Analysis of the Population-Based SABR-5 Phase II Trial.

AIMS: Most patients experience stable quality of life (QoL) after stereotactic ablative radiotherapy (SABR) treatment for oligometastases. However, a subset of patients experience clinically relevant declines in QoL on post-treatment follow-up. This study aimed to identify risk factors for QoL decline. MATERIALS AND METHODS: The SABR-5 trial was a population-based single-arm phase II study of SABR to up to five sites of oligometastases. Prospective QoL was measured using treatment site-specific tools at pre-treatment baseline and 3, 6, 9, 12, 15, 18, 21, 24, 30 and 36 months after treatment. The time to persistent QoL decline was calculated as the time from SABR to the first decline in QoL score meeting minimum clinically important difference with no improvement to baseline score on subsequent assessments. Univariable and multivariable logistic regression analyses were carried out to determine factors associated with QoL decline. RESULTS: One hundred and thirty-three patients were included with a median follow-up of 32 months (interquartile range 25-43). Thirty-five patients (26%) experienced a persistent decline in QoL. The median time until persistent QoL decline was not reached. The cumulative incidence of QoL decline at 2 and 3 years were 22% (95% confidence interval 14.0-29.6) and 40% (95% confidence interval 28.0-51.2), respectively. In multivariable analysis, disease progression (odds ratio 5.23, 95% confidence interval 1.59-17.47, P = 0.007) and adrenal metastases (odds ratio 9.70, 95% confidence interval 1.41-66.93, P = 0.021) were associated with a higher risk of QoL decline. Grade 3 or higher (odds ratio 3.88, 95% confidence interval 0.92-16.31, P = 0.064) and grade 2 or higher SABR-associated toxicity (odds ratio 2.24, 95% confidence interval 0.85-5.91, P = 0.10) were associated with an increased risk of QoL decline but did not reach statistical significance. CONCLUSIONS: Disease progression and adrenal lesion site were associated with persistent QoL decline following SABR. The development of grade 3 or higher toxicities was also associated with an increased risk, albeit not statistically significant. Further studies are needed, focusing on the QoL impact of metastasis-directed therapies.

Prospective Longitudinal Assessment of Quality of Life After Stereotactic Ablative Radiotherapy for Oligometastases: Analysis of the Population-based SABR-5 Phase II Trial.

AIMS: To evaluate longitudinal patient-reported quality of life (QoL) in patients treated with stereotactic ablative radiotherapy (SABR) for oligometastases. MATERIALS AND METHODS: The SABR-5 trial was a population-based single-arm phase II study of SABR to up to five sites of oligometastases, conducted in six regional cancer centres in British Columbia, Canada from 2016 to 2020. Prospective QoL was measured using treatment site-specific QoL questionnaires at pre-treatment baseline and at 3, 6, 9, 12, 15, 18, 21, 24, 30 and 36 months after treatment. Patients with bone metastases were assessed with the Brief Pain Inventory (BPI). Patients with liver, adrenal and abdominopelvic lymph node metastases were assessed with the Functional Assessment of Chronic Illness Therapy-Abdominal Discomfort (FACIT-AD). Patients with lung and intrathoracic lymph node metastases were assessed with the Prospective Outcomes and Support Initiative (POSI) lung questionnaire. The two one-sided test procedure was used to assess equivalence between the worst QoL score and the baseline score of individual patients. The mean QoL at all time points was used to determine the trajectory of QoL response after SABR. The proportion of patients with 'stable', 'improved' or 'worsened' QoL was determined for all time points based on standard minimal clinically important differences (MCID; BPI worst pain = 2, BPI functional interference score [FIS] = 0.5, FACIT-AD Trial Outcome Index [TOI] = 8, POSI = 3). RESULTS: All enrolled patients with baseline QoL assessment and at least one follow-up assessment were analysed (n = 133). On equivalence testing, the patients' worst QoL scores were clinically different from baseline scores and met MCID (BPI worst pain mean difference: 1.8, 90% confidence interval 1.19 to 2.42]; BPI FIS mean difference: 1.68, 90% confidence interval 1.15 to 2.21; FACIT-AD TOI mean difference: -8.76, 90% confidence interval -11.29 to -6.24; POSI mean difference: -4.61, 90% confidence interval -6.09 to -3.14). However, the mean FIS transiently worsened at 9, 18 and 21 months but eventually returned to stable levels. The mean FACIT and POSI scores also worsened at 36 months, albeit with a limited number of responses (n = 4 and 8, respectively). Most patients reported stable QoL at all time points (range: BPI worst pain 71-82%, BPI FIS 45-78%, FACIT-AD TOI 50-100%, POSI 25-73%). Clinically significant stability, worsening and improvement were seen in 70%/13%/18% of patients at 3 months, 53%/28%/19% at 18 months and 63%/25%/13% at 36 months. CONCLUSIONS: Transient decreases in QoL that met MCID were seen between patients' worst QoL scores and baseline scores. However, most patients experienced stable QoL relative to pre-treatment levels on long-term follow-up. Further studies are needed to characterise patients at greatest risk for decreased QoL.

Validation of the Prognostic Utility of ESTRO/EORTC Oligometastatic Disease Classification: A Secondary Analysis From the Population-Based Phase II SABR-5 Trial.

PURPOSE: The recently developed European Society for Radiotherapy and Oncology (ESTRO)/European Organization for Research and Treatment of Cancer (EORTC) oligometastatic disease (OMD) classification has not been validated in terms of its prognostic significance. This study stratified patients from the phase II SABR-5 trial based on ESTRO/EORTC criteria and compared progression-free survival (PFS) and overall survival (OS) to determine the prognostic significance of the classification scheme. METHODS AND MATERIALS: The SABR-5 trial was a single arm phase II study conducted at the 6 regional cancer centers across British Columbia (BC), Canada, where SABR for oligometastases was only offered on trial. Patients with up to 5 oligometastases (total or not controlled by prior treatment and including induced OMD) underwent SABR to all lesions. Patients were 18 years of age or older, Eastern Cooperative Oncology Group 0 to 2, and life expectancy ≥6 months. PFS and OS were calculated using the Kaplan-Meier method and differences between OMD groups were assessed with log-rank tests. Univariable and multivariable analyses were performed using Cox regression modeling. RESULTS: Between November 2016 and July 2020, 381 patients underwent SABR on trial. Median follow-up was 27 months (interquartile range, 18-36). The most frequent OMD group was de novo OMD (69%), followed by repeat (16%) and induced (13%). OMD groups differed significantly in PFS (P < .001) but not OS (P = .069). The OMD classification was an independent predictor of both PFS (P = .005) and OS (P = .002). Of the 5 classification factors, only chronicity (synchronous, hazard ratio, 0.52; P = .027) and oligoprogression (hazard ratio, 2.05; P = .004) were independently prognostic for OS. CONCLUSIONS: In this large prospective cohort, the ESTRO/EORTC classification was an independent predictor of PFS and OS and should be used to identify specific patient groups for clinical trials. In this trial population, the prognostic power is largely attributable to chronicity and oligoprogression. Simplification of the framework may be possible in the future and allow for greater ease of use; however, further data on underrepresented OMD groups and histologies will be required.

The Effect of Breast Cancer Subtype on Symptom Improvement Following Palliative Radiotherapy for Bone Metastases.

AIM: To assess the relationship between breast cancer subtypes and patient-reported outcomes (PRO) following palliative radiotherapy for bone metastases. MATERIALS AND METHODS: Prospectively collected PRO for all breast cancer patients treated with palliative, bone metastasis-directed radiotherapy from 2013 to 2016 in the province of British Columbia were analysed. The PRO questionnaire scored pain severity, level of function and symptom frustration at baseline and at 3-4 weeks following palliative radiotherapy using a 12-point scale. The primary outcome was the rate of overall response (any improvement in score); the secondary outcome was the rate of complete improvement in PRO (final PRO score of 0). Multivariate logistic analysis was used to compare response rates between molecular subgroup approximations of luminal A (LumA), luminal B (LumB), HER2-enriched (HER2) and triple negative (TN), as defined by grade and immunohistochemical staining. RESULTS: There were 376 patients who underwent 464 courses of palliative radiation for bone metastases. Subtypes included: 243 LumA, 146 LumB, 46 HER2 and 29 TN. There were 216 multifraction radiotherapy courses (median dose 20 Gy) and 248 single-fraction radiotherapy courses (median dose 8 Gy). The overall response rate was 85% and the complete response rate was 25%. In comparison with LumA breast cancers, TN breast cancers were associated with a lower rate of overall response (69% versus 86%, P = 0.021) and a lower rate of complete response (10% versus 28.8%, P = 0.045) on multivariate analyses. CONCLUSION: Patients with TN breast cancer have lower rates of pain, function and symptom frustration improvement following palliative radiation for bone metastases.

Spine and Non-spine Bone Metastases - Current Controversies and Future Direction.

Bone is a common site of metastases in advanced cancers. The main symptom is pain, which increases morbidity and reduces quality of life. The treatment of bone metastases needs a multidisciplinary approach, with the main aim of relieving pain and improving quality of life. Apart from systemic anticancer therapy (hormonal therapy, chemotherapy or immunotherapy), there are several therapeutic options available to achieve palliation, including analgesics, surgery, local radiotherapy, bone-seeking radioisotopes and bone-modifying agents. Long-term use of non-steroidal analgesics and opiates is associated with significant side-effects, and tachyphylaxis. Radiotherapy is effective mainly in localised disease sites. Bone-targeting radionuclides are useful in patients with multiple metastatic lesions. Bone-modifying agents are beneficial in reducing skeletal-related events. This overview focuses on the role of surgery, including minimally invasive treatments, conventional radiotherapy in spinal and non-spinal bone metastases, bone-targeting radionuclides and bone-modifying agents in achieving palliation. We present the clinical data and their associated toxicity. Recent advances are also discussed.

A catalyst for transforming health systems and person-centred care: Canadian national position statement on patient-reported outcomes.

Background: Patient-reported outcomes (pros) are essential to capture the patient's perspective and to influence care. Although pros and pro measures are known to have many important benefits, they are not consistently being used and there is there no Canadian pros oversight. The Position Statement presented here is the first step toward supporting the implementation of pros in the Canadian health care setting. Methods: The Canadian pros National Steering Committee drafted position statements, which were submitted for stakeholder feedback before, during, and after the first National Canadian Patient Reported Outcomes (canpros) scientific conference, 14-15 November 2019 in Calgary, Alberta. In addition to the stakeholder feedback cycle, a patient advocate group submitted a section to capture the patient voice. Results: The canpros Position Statement is an outcome of the 2019 canpros scientific conference, with an oncology focus. The Position Statement is categorized into 6 sections covering 4 theme areas: Patient and Families, Health Policy, Clinical Implementation, and Research. The patient voice perfectly mirrors the recommendations that the experts reached by consensus and provides an overriding impetus for the use of pros in health care. Conclusions: Although our vision of pros transforming the health care system to be more patient-centred is still aspirational, the Position Statement presented here takes a first step toward providing recommendations in key areas to align Canadian efforts. The Position Statement is directed toward a health policy audience; future iterations will target other audiences, including researchers, clinicians, and patients. Our intent is that future versions will broaden the focus to include chronic diseases beyond cancer.

Metabolic tumour volume is prognostic in patients with non-small-cell lung cancer treated with stereotactic ablative radiotherapy.

Introduction: Stereotactic ablative radiotherapy (sabr) is a relatively new technique for the curative-intent treatment of patients with inoperable early-stage non-small-cell lung cancer (nsclc). Previous studies have demonstrated a prognostic value for positron emission tomography-computed tomography (pet/ct) parameters, including maximal standardized uptake value (suvmax), metabolic tumour volume (mtv), and total lesion glycolysis (tlg) in lung cancer patients. We aimed to determine which pet/ct parameter is most prognostic of local control (lc) and overall survival (os) in patients treated with sabr for nsclc. Methods: We conducted a retrospective review of patients treated with sabr for stage I inoperable nsclc at BC Cancer between 2009 and 2013. The Akaike information criterion was used to compare the prognostic value of the various pet/ct parameters. Results: The study included 134 patients with a median age of 76 years. Median tumour diameter was 2.2 cm, gross tumour volume was 8.1 mL, suvmax was 7.9, mtv was 2.4 mL, and tlg was 10.9 suv·mL. The 2-year lc was 92%, and os was 66%. On univariate and multivariate analysis, imaging variables including tumour size, gross tumour volume, suvmax, mtv, and tlg were all associated with worse lc. Tumour size was not associated with significantly worse os, but other imaging variables were. The pet/ct parameter most prognostic of lc was mtv. Compared with suvmax, tlg and mtv were more prognostic of os. Conclusions: In patients with early-stage nsclc treated with sabr, mtv appears to be prognostic of lc and os.

Prescribing practices of endocrine therapy for ductal carcinoma in situ in British Columbia.

Purpose: The mainstay of treatment for ductal carcinoma in situ (dcis) involves surgery in the form of mastectomy or lumpectomy. Inconsistency in the use of endocrine therapy (et) for dcis is evident worldwide. We sought to assess the variation in et prescribing for patients with dcis across a population-based radiotherapy (rt) program and to identify variables that predict its use. Methods: Data from a breast cancer database were obtained for women diagnosed with dcis in British Columbia from 2009 to 2014. Associations between et use and patient characteristics were assessed by chi-square test and multilevel multivariate logistic regression. The Kaplan-Meier method, with propensity score matching and Cox regression analysis, was used to assess the effects of et on overall survival (os) and relapse-free survival (rfs). Results: For the 2336 dcis patients included in the study, et use was 13% in dcis patients overall, and 17% in patients with estrogen receptor-positive (er+) tumours treated with breast-conserving surgery and rt. Significant variation in et use by treatment centre was observed (range: 8%-23%; p < 0.001), and prescription of et by individual oncologists varied in the range 0%-40%. After controlling for confounding factors, age less than 50 years [odds ratio (or): 1.72; p = 0.01], treatment centre, er+ status (or: 5.33; p < 0.001), and rt use (or: 1.77; p < 0.001) were significant predictors of et use. No difference in os or rfs with the use of et was observed. Conclusions: In this population-based analysis, 13% of patients with dcis in British Columbia received et, with variation by treatment centre (8%-23%) and individual oncologist (0%-40%). Age less than 50 years, er+ status, and rt use were most associated with et use.

Factors affecting radiotherapy prescribing patterns in the post-mastectomy setting.

Background: Radiation therapy (rt) after mastectomy for breast cancer can improve survival outcomes, but has been associated with inferior cosmesis after breast reconstruction. In the literature, rt dose and fractionation schedules are inconsistently reported. We sought to determine the pattern of rt prescribing practices in a provincial rt program for patients treated with mastectomy and reconstruction. Methods: Women diagnosed with stages 0-iii breast cancer between January 2012 and December 2013 and treated with curative-intent rt were identified from a clinicopathology database. Patient demographic, tumour, and treatment information were extracted. Of the identified patients, those undergoing mastectomy were the focus of the present analysis. Results: Of 4016 patients identified, 1143 (28%) underwent mastectomy. The patients treated with mastectomy had a median age of 57 years, and 37% of them underwent reconstruction. Treatment with more than 16 fractions of rt was associated with autologous reconstruction [odds ratio (or): 37.2; 95% confidence interval (ci): 11.2 to 123.7; p < 0.001], implant reconstruction (or: 93.3; 95% ci: 45.3 to 192.2; p < 0.001), and treating centre. Hypofractionated treatment was associated with older age (or: 0.94; 95% ci: 0.92 to 0.96; p < 0.001), and living more than 400 km from a treatment centre (or: 0.37; 95% ci: 0.16 to 0.86; p = 0.02). Conclusions: Prescribing practices in breast cancer patients undergoing mastectomy are influenced by reconstruction intent, age, nodal status, and distance from the treatment centre. Those factors should be considered when making treatment decisions.

Assessing post-radiotherapy handover notes from a family physician perspective.

BACKGROUND: Across our province, post-radiotherapy (rt) handover notes are sent to family physicians (fps) after rt. Based on previous fp feedback, we created a revised post-radiotherapy handover note with more information requested by fps. The purpose of this study was to determine whether the revised handover note improved the note as a communication aid. METHODS: Potential common and rare treatment side effects, oncologist contact information, and treatment intent were added to the revised handover note. Both versions were sent alongside a questionnaire to fps. Paired t-tests were carried out to compare satisfaction differences. RESULTS: There was a response rate of 37% for the questionnaires. Significantly greater clarity in the following categories was observed: responsibility for patient follow-up (mean score improvement of 1.2 on a 7-point Likert scale, p < 0.001), follow-up schedule (1.1, p < 0.001) as well as how and when to contact the oncologist (1.4, p = 0.001). Family physicians were also more content with how the institute transitioned care back to them (1.5, p = 0.012). Overall, fps were generally satisfied with the content of the revised post-rt handover note and noted improvement over the previous version. The frequency of investigations and institute supports initiated such as counselling services were suggested further additions. CONCLUSIONS: The inclusion of potential treatment side effects, oncologist contact information, treatment intent and a well-laid out follow-up schedule were essential information needed by fps for an effective post-rt completion note. With these additions, the revised post-rt handover note showed significant improvement.

Patient-reported outcome use in oncology: a systematic review of the impact on patient-clinician communication.

PURPOSE: Patient-reported outcomes (PROs) are an increasingly popular tool to optimize care and bridge the gap between patient experience and clinician understanding. The aim of this review was to identify mechanisms through which PROs facilitate patient-clinician communication in the adult oncology population. METHODS: We conducted a systematic review of the published literature using the following data sources: MEDLINE, EMBASE, CINAHL, PsycINFO, Cab Direct, and CDSR. Studies included in this review reported on the outcomes of PRO use, used PROs as an intervention and not as a study outcome measurement tool, included cancer patients or survivors as study participants, and analyzed patient-clinician communication. RESULTS: We identified 610 unique records, of which 43 publications met the inclusion and exclusion criteria. Synthesis of the reviewed studies provided evidence of the usefulness of PROs in facilitating patient-clinician communication on a variety of topics. We identified mechanisms though which PROs influenced patient-clinician communication to include increasing symptom awareness, prompting discussion, streamlining consultations, and facilitating inter-professional communication. Barriers to PRO use in communication improvement include technical problems impeding its administration and completion, compliance issues due to lack of incentive or forgetfulness, and use of PROs that do not appropriately assess issues relevant to the patient. Facilitators include increased education on PRO use, using PRO tools that patients find more acceptable, and providing patient data summaries in an easily accessible format for clinicians. CONCLUSIONS: Our review suggests that PROs facilitate patient-clinician communication through various mechanisms that could perhaps contribute to improvements in symptom management and survival. The impact of PROs on clinical outcomes, however, remains poorly studied.

Neoadjuvant systemic therapy in breast cancer: use and trends in radiotherapy practice.

BACKGROUND: The use of neoadjuvant systemic therapy (nast) in the treatment of breast cancer is increasing, and the role of adjuvant radiation therapy (rt) in that setting is uncertain. We sought to review and report the use of nast, its trends over time, and its relationship with the prescribing patterns of locoregional rt in a provincial cancer system. METHODS: Patients with stages i-iii breast cancer diagnosed during 2007-2012 were identified using a provincial database. Patient, tumour, and treatment characteristics were extracted. Multivariable logistic regression analyses were used to assess associations with the use of nast. Kaplan-Meier and Cox regression were used for survival analyses. RESULTS: Of the 11,658 patients who met the inclusion criteria, 602 (5%) had received nast. Use of nast was more frequent in stage iii patients (53%) than in stages i and ii patients (2%). In clinically lymph-node positive patients, a pathology assessment was made approximately 50% of the time. Higher clinical tumour stage and increasing clinical nodal stage predicted for increasing use of nast and of nodal rt after nast, but pathologic nodal status after nast was not associated with use of nodal rt. A statistically significant survival difference was observed between patients in the nast and no-nast groups, but that significance disappeared in a multivariable Cox regression analysis. CONCLUSIONS: This population-based study demonstrated 5% use of nast for breast cancer. Most patients received nodal rt after nast, and nodal rt was not associated with pathologic stage after nast. Findings likely reflect the realities of clinical practice and show that reliance on clinical nodal staging results in outcomes similar to those reported in the literature.

Patient preferences for timing and access to radiation therapy.

PURPOSE: Patient preferences for radiation therapy (rt) access were investigated. METHODS: Patients completing a course of rt at 6 centres received a 17-item survey that rated preferences for time of day; day of week; actual, ideal, and reasonable travel times for rt; and actual, ideal, and reasonable times between referral and first oncologic consultation. Patients receiving single-fraction rt or brachytherapy alone were excluded. RESULTS: Of the respondents who returned surveys (n = 1053), 54% were women, and 74% had received more than 15 rt fractions. With respect to appointment times, 88% agreed or strongly agreed that rt between 08h00 and 16h30 was preferred; 14%-15% preferred 07h30-08h00 or 16h30-17h00; 10% preferred 17h00-18h00; and 6% or fewer preferred times before 07h30 or after 18h00. A preference not to receive rt before 07h30 or after 18h00 was expressed by 30% or more of the respondents. When days of the week were considered, 18% and 11% would have preferred to receive rt on a Saturday or Sunday respectively; 52% and 55% would have preferred not to receive rt on those days. A travel time of 1 hour or less for rt was reported by 82%, but 61% felt that a travel time of 1 hour or more was reasonable. A first consultation within 2 weeks of referral was felt to be ideal or reasonable by 88% and 73% of patients respectively. CONCLUSIONS: An rt service designed to meet patient preferences would make most capacity available between 08h00 and 16h30 on weekdays and provide 10%-20% of rt capacity on weekends and during 07h30-08h00 and 16h30-18h00 on weekdays. Approximately 80%, but not all, of the responding patients preferred a 2-week or shorter interval between referral and first oncologic consultation.

Genome-wide screening for DNA variants associated with reading and language traits.

Reading and language abilities are heritable traits that are likely to share some genetic influences with each other. To identify pleiotropic genetic variants affecting these traits, we first performed a genome-wide association scan (GWAS) meta-analysis using three richly characterized datasets comprising individuals with histories of reading or language problems, and their siblings. GWAS was performed in a total of 1862 participants using the first principal component computed from several quantitative measures of reading- and language-related abilities, both before and after adjustment for performance IQ. We identified novel suggestive associations at the SNPs rs59197085 and rs5995177 (uncorrected P ≈ 10(-7) for each SNP), located respectively at the CCDC136/FLNC and RBFOX2 genes. Each of these SNPs then showed evidence for effects across multiple reading and language traits in univariate association testing against the individual traits. FLNC encodes a structural protein involved in cytoskeleton remodelling, while RBFOX2 is an important regulator of alternative splicing in neurons. The CCDC136/FLNC locus showed association with a comparable reading/language measure in an independent sample of 6434 participants from the general population, although involving distinct alleles of the associated SNP. Our datasets will form an important part of on-going international efforts to identify genes contributing to reading and language skills.

25 year survival outcomes for squamous cell carcinomas of the head and neck: population-based outcomes from a Canadian province.

OBJECTIVES: Long term outcomes of patients with head and neck cancer (HNC) are rarely reported, but of potential benefit to clinicians and researchers. Squamous cell carcinomas (SCC) of the head and neck represent a heterogeneous group of cancers. The purpose of this population based study is to describe primary site specific, long term outcomes of HNC. METHODS: All patients from a Canadian province diagnosed between 1986 and 1990 with SCC of the oral cavity, pharynx, and larynx were identified. Chart review and patient data were abstracted through the provincial cancer registry database. Survival analysis was performed with Kaplan Meier methods, while differences in survival between groups were assessed with log-rank tests. Multivariable analysis was performed using Cox-regression. RESULTS: 1657 patients were analyzed during the study period. Almost half (50.9%) of the cases were advanced stage (stage III IV) at presentation. Two, 5, 15 & 25year overall survival (OS) and HNC specific survival for all the patients were 64%, 46%, 21%, 11% and 74%, 63%, 53% & 49%, respectively. OS and HNC-specific mortality were statistically inferior among men, older age at diagnosis, advanced stages of disease, and was primary cancer site specific, with worse survival in oropharyngeal & hypopharyngeal sites, p<0.001. CONCLUSIONS: Survival rates vary by primary HNC site, and the overall survival & HNC specific survival differ over this long follow up assessment. Head and neck cancer specific death is most common in the first five years, and is subsequently dominated by competing causes of mortality. These results are useful as a reference tool for clinicians, researchers, and trainees.

Prospective evaluation of unmet needs of rural and aboriginal cancer survivors in Northern British Columbia.

BACKGROUND: The unmet needs of cancer survivors in rural, remote, and aboriginal communities are largely unexplored. We explored potential differences between rural survivors (rss) in 4 general population (gp) and 4 First Nations (fn) communities. METHODS: We approached 4 gp and 4 fn rs communities to participate in a mixed-methods project. Participants completed the Hospital Anxiety and Depression Scale (hads) and the Survivor Unmet Needs Survey (suns) and provided demographic information. Each question on the suns can be scored from 0 to 4, with 0 representing "no unmet need" and 4 representing "very high unmet need." A directed approach to content analysis of focus group and interview data was used to triangulate the hads and suns results. RESULTS: We prospectively accrued 23 fn rss and 56 gp rss for this study. More fn rss had borderline or abnormal anxiety (5% vs. 21%, p = 0.02). Compared with gp rss, fn rss had higher unmet needs scores in all categories: Information (2.29 vs. 0.8, p < 0.001), Work and Financial (1.66 vs. 0.5, p < 0.001), Access and Continuity of Health Care (1.83 vs. 0.44, p < 0.001), Coping and Sharing (2.22 vs. 0.62, p < 0.001), and Emotional (2.12 vs. 0.63, p < 0.001). The qualitative findings provided examples and insight into the unmet needs experienced by rss. CONCLUSIONS: First Nations rss had significantly higher anxiety and unmet needs compared with their gp rs counterparts. In addition, different qualitative themes were identified in the groups. Our findings support the development of tailored approaches to survivorship for these populations.

Indefinite loss: the experiences of carers of a spouse with cancer.

Cancer trajectories now follow a jagged path based on multiple probabilities. Thus, uncertainty now typifies cancer caregiving. What impact does uncertainty have on cancer carer grief? This article explores cancer carers' experiences of loss, based on qualitative interviews with 32 Australian carers of a spouse with cancer. Findings suggest that in addition to conventional and anticipatory grief, many carers experience indefinite loss. Indefinite loss characterised the experiences of spouses caregiving outside of the terminal stage. They experienced the current loss of a taken-for-granted certain future, but the future loss of their spouse remained uncertain. They described a heightened awareness of mortality, and an inability to plan for the future. Losses that are uncertain and potential are largely neglected within the grief literature. In this article, I offer the concept indefinite loss and extend health professionals' understanding of cancer carer loss.

A time-sovereignty approach to understanding carers of cancer patients' experiences and support preferences.

Much of the literature on informal carers of cancer patients is quantitative and psycho-oncology based. This literature has established that cancer carers experience higher rates of stress, depression and anxiety than their non-caregiving counterparts, with younger female carers reporting higher rates of burden and unmet needs. The reasons behind this variation and variations in support preferences are poorly understood: some carers prefer support groups and others prefer practical support. This study takes a sociological approach to exploring carers' varied experiences. Longitudinal interviews were conducted with 32 carers of a spouse with cancers of varying stages and diagnoses in the Australian Capital Territory. Analysis, informed by the discretionary time literature, shows time-sovereignty illuminates much of the variation in carers' emotional experiences and support preferences. Carers with few competing commitments and less onerous caregiving responsibilities had time to experience and unpack the range of emotions associated with cancer, and reconnect with their spouse. These carers preferred emotion-focused support. In contrast, carers with multiple commitments had little time to themselves and viewed emotions as an indulgence. These carers preferred practical support. A time-sovereignty framework offers health and support professionals a means of understanding carers' varying needs and tailoring support services.

Comparison of recurrence and survival rates after breast-conserving therapy and mastectomy in young women with breast cancer.

Multiple randomized trials have demonstrated that breast-conserving therapy with partial mastectomy and radiotherapy provides survival equivalent to that seen with mastectomy for patients with early-stage breast cancer. Breast-conserving therapy has been associated with better quality of life relative to mastectomy and has become the standard of care for patients with early-stage breast cancer. Young age has been identified as a risk factor for recurrence and death from breast cancer. Some studies have suggested that young women (less than 35 or 40 years of age) have inferior outcomes with breast-conserving therapy, implying that such women may be better served by mastectomy. On review of the available literature, there is no definitive evidence that mastectomy provides a consistent, unequivocal recurrence-free or overall survival benefit over breast-conserving therapy. However, available meta-analyses have not compared outcomes in young women specifically, and such analyses should be performed. In the interim, breast-conserving therapy is not contraindicated in young women (less than 40 years of age) and can be used cautiously; however, such women should be advised of the lack of unequivocal data proving that survival is equivalent to that with mastectomy in their age group.
