Comparison of wait times across the breast cancer treatment pathway among screened women undergoing organized breast assessment versus usual care.

OBJECTIVE: The benefit of organized breast assessment on wait times to treatment among asymptomatic women is unknown. The Ontario Breast Screening Program (OBSP) offers screening and organized assessment through Breast Assessment Centres (BAC). This study compares wait times across the treatment pathway among screened women diagnosed with breast cancer through BAC and usual care (UC). METHODS: A retrospective design identified two concurrent cohorts of postmenopausal women aged 50-69 within the OBSP diagnosed with screen-detected invasive breast cancer and assessed in BAC (n = 2010) and UC (n = 1844) between 2002 and 2010. Demographic characteristics were obtained from the OBSP. Medical chart abstraction provided prognostic and treatment data. Multinomial logistic regression examined associations of assessment type with wait times from abnormal mammogram to surgery, chemotherapy or radiotherapy. RESULTS: Compared with through UC, postmenopausal women diagnosed through BAC were significantly less likely to have longer wait times (days) from an abnormal mammogram to definitive surgery (> 89 vs. ≤ 47; OR = 0.63; 95% CI = 0.52-0.77), from final surgery to radiotherapy (> 88 vs. ≤ 55; OR = 0.71; 95% CI = 0.54-0.93) and from final chemotherapy to radiotherapy (> 41 vs. ≤ 28; OR = 0.52; 95% CI = 0.36-0.76). Conversely, women assessed through BAC compared with through UC were more likely to experience longer wait times from final surgery to chemotherapy (> 64 vs. ≤ 40; OR = 1.49; 95% CI = 1.04-2.14). CONCLUSION: Shorter wait times to most treatments for postmenopausal women diagnosed in BAC further supports that women with an abnormal mammogram should be managed through organized assessment. Continued evaluation of factors influencing wait times to treatment is essential for quality improvement and patient outcomes.

The impact of organized breast assessment on survival by stage for screened women diagnosed with invasive breast cancer.

PURPOSE: Since 1998, the Ontario Breast Screening Program (OBSP) has offered organized assessment through Breast Assessment Centres (BAC). This study compares survival between screened women diagnosed with breast cancer who have undergone assessment through a BAC and usual care (UC). METHODS: A retrospective design identified two concurrent cohorts of women aged 50 to 69 within the OBSP diagnosed with screen-detected invasive breast cancer at a BAC (n = 2010) and UC (n = 1844) between 2002 and 2010 and followed until 2016. Demographic and assessment characteristics were obtained from the OBSP. Abstraction of medical charts provided prognostic and treatment data. Death data were assessed from the Registered Person's Database and the Ontario Registrar General All-Cause Mortality File. Multivariable Cox proportional hazards models compared overall survival by assessment type (BAC/UC), stratified by stage. RESULTS: There were 505 deaths during the study (BAC = 239; UC = 266). Among women with stage I screen-detected breast cancer, those diagnosed through a BAC had 31% reduced risk of all-cause mortality (HR = 0.69, 95% CI = 0.53-0.90) compared to UC. Diagnosis within 7 weeks of an abnormal mammogram reduced the hazard of death from all causes by 34% among all women with stage I breast cancers (HR = 0.66, 95% CI = 0.47-0.91), and was more likely in BAC (79.7%) than UC (66.9%). CONCLUSION: The significant improvement in overall survival for women with stage I screen-detected invasive breast cancer assessed through BACs further supports the recommendation that women with abnormal mammograms should be managed through organized assessment.

Validity of Administrative Databases in Comparison to Medical Charts for Breast Cancer Treatment Data.

OBJECTIVE: Medical chart abstraction is the gold standard for collecting breast cancer treatment data for monitoring and research. A less costly alternative is the use of administrative databases. This study will evaluate administrative data in comparison to medical charts for breast cancer treatment information. STUDY DESIGN AND SETTING: A retrospective cohort design identified 2,401 women in the Ontario Breast Screening Program diagnosed with invasive breast cancer from 2006 to 2009. Treatment data were obtained from the Activity Level Reporting and Canadian Institute of Health Information databases. Medical charts were abstracted at cancer centres. Sensitivity, specificity, positive and negative predictive value, and kappa were calculated for receipt and type of treatment, and agreement was assessed for dates. Logistic regression evaluated factors influencing agreement. RESULTS: Sensitivity and specificity for receipt of radiotherapy (92.0%, 99.3%), chemotherapy (77.7%, 99.2%), and surgery (95.8%, 100%) were high but decreased slightly for specific radiotherapy anatomic locations, chemotherapy protocols, and surgeries. Agreement increased by radiotherapy year (trend test, p < 0.0001). Stage II/III compared to stage I cancer decreased odds of agreement for chemotherapy (OR = 0.66, 95% CI: 0.48-0.91) and increased agreement for partial mastectomy (OR = 3.36, 95% CI: 2.27-4.99). Exact agreement in treatment dates varied from 83.0% to 96.5%. CONCLUSION: Administrative data can be accurately utilized for future breast cancer treatment studies.

Prevalence of Physiologic Sexual Dysfunction Is High Following Treatment for Rectal Cancer: But Is It the Only Thing That Matters?

BACKGROUND: Although several studies have reported high rates of sexual dysfunction in patients treated for rectal cancer, most studies have been limited by retrospective design, failure to use validate instruments, and a limited number of female patients. OBJECTIVES: The objectives of this study were to 1) prospectively assess changes in sexual function before and after treatment for rectal cancer and 2) identify potential areas for improved care of patients who have rectal cancer with sexual dysfunction. DESIGN: This study is a prospective, longitudinal survey. SETTINGS: This study was conducted at 4 tertiary care academic hospitals. PATIENTS: The patients included had newly diagnosed rectal cancer. MAIN OUTCOME MEASURES: Subjects completed the European Organization for Research and Treatment Quality of Life Cancer Module and Colorectal Cancer Module, International Index of Erectile Function, and Female Sexual Function Index questionnaires before the start of treatment, after the completion of preoperative chemoradiotherapy, and 1 year after surgery. RESULTS: Forty-five patients completed the study, and the overall results showed significant sexual dysfunction in both male and female subjects that continued to increase from baseline up to 1 year after surgery. In male subjects, sexual activity, interest, and enjoyment remained relatively stable, despite increasing sexual problems. However, for female patients, although sexual activity and interest remained relatively stable, sexual enjoyment worsened as sexual problems increased. LIMITATIONS: The study closed before reaching the target sample size owing to lower than anticipated accrual rates. Post hoc analysis included qualitative interviews with patients to explore reasons for low recruitment. CONCLUSIONS: The results of this study show that sexual problems continue to increase up to 1 year after surgery. Despite this, sexual interest in both male and female patients remained relatively unchanged suggesting that other aspects of sexuality, not just physiologic function, also need to be evaluated. Future studies to assist and educate physicians on how to initiate a discussion about sexuality and identify patients in "distress" because of sexual problems are important.

Introducing a patient-focused care map in colorectal surgery: a pilot qualitative study of patients' and surgical oncology nurses' experiences.

Care maps for patient care have been around for many years. Key stakeholders at our institution developed and implemented a care map for patients undergoing surgery for colorectal cancer. The purpose of this descriptive, qualitative pilot study was twofold. First was to understand the lived experience of patients being cared for under a newly-implemented care map utilizing patient diaries and interviews. The second goal was to describe the experiences of surgical oncology nurses caring for these patients using a focus group technique. The results of our small study indicated that patients appreciated having a document that outlines daily activities and goals, and were anxious to get home, but were disappointed in the discharge planning process. Nurses were positive about the care map overall, but felt they could have contributed more in the development and planning stages of the care map. Overall, the implementation of our patient-centred care map was a success.

Compliance, attitudes and barriers to post-operative colorectal cancer follow-up.

RATIONALE: Meta-analyses demonstrate that surveillance following curative-intent colorectal cancer (CRC) surgery can improve survival. Our multidisciplinary team adopted a stringent CRC follow-up (FU) guideline in 2000. The purpose of this study was to assess adherence and barriers to FU for CRC. METHODS: Patients with primary CRC aged 19-75 years, treated with curative intent surgery from July 2000 to December 2002 were identified from a prospective database. Compliance with FU was assessed primarily by chart review. We also surveyed patients and providers to explore attitudes and barriers to surveillance adherence using tenets of the Health Belief Model. RESULTS: 96 patients met inclusion criteria and were appropriate for FU. Median FU was 34 months. Guideline targets were met for 70% of clinic visits; 49% of carcinoembryonic antigen (CEA) determinations; and 62% of abdominal imaging studies. Post-operative colonoscopy did not occur in 6/93 patients. Seventy per cent of health care providers and 55% of patients completed a survey. Access to testing and confusion about which provider orders investigations were identified as important barriers to FU. CONCLUSION: Patterns of CRC FU were widely variable despite implementation of a guideline. Despite patient and provider agreement with the principles of CRC FU, adoption was inhibited by confusion among multiple providers regarding investigation coordination.

Interest and participation in support group programs among patients with colorectal cancer.

Previous studies have demonstrated that support intervention improved quality of life and survival for patients with breast, melanoma, prostate, and gastrointestinal cancer. A standardized approach to encourage participation in support group programs among patients with colorectal cancer (CRC) had been initiated at this study site. The purpose of this study was to examine the characteristics of patients with CRC interested in this type of intervention and to identify barriers to attendance at an established patient support program. Consecutive patients with CRC were informed and encouraged to attend Wellspring, a nonprofit patient support program that offers a wide range of services. A patient survey was conducted and correlated with data on the clinical, social, and demographic characteristics of patients. Factors predictive of interest in the Wellspring support program and barriers to attendance were examined.Fifty-eight patients were eligible for this study. A total of 44 (76%) surveys were completed. Predictors of interest in patient support were age less than 65 years, encouragement from medical staff to attend, level of education, comfort in spiritual beliefs, religious affiliation, and complementary/alternative medicine use. Disease stage, gender, ethnicity, and level of social supports were not significant in this population. Although patients were routinely informed about the program in a standardized fashion, a significant proportion (36.4%) of patients did not recall receiving encouragement. Multiple logistic regression showed that level of education and recollection of encouragement from medical staff were independent predictors of interest. Although 14 patients were interested in attending (32%), only 4 ultimately attended Wellspring programs (9.1%). The most frequently cited barrier to attendance was a perception of adequate support at home, followed by living too far away, no perceived need of supports, and not feeling well.A significant proportion of patients with CRC are interested in structured support programs, but only a minority of patients ultimately participate in such programs. Further participation may be achieved by recognizing common barriers to participation and optimizing strategies to enhance attendance. Optimizing use of support services such as Wellspring has the potential to improve the effectiveness of the multidisciplinary cancer care of patients with CRC.
