A nationwide analysis of geriatric proximal humerus fractures: trends, outcomes, and cost.

Background: In the USA, proximal humerus fractures (PHF) are the third most common fracture among the elderly. Although most geriatric PHF are treated conservatively, surgical management remains an option. This retrospective study compares annual trends, patient outcomes, and hospital costs between operatively and non-operatively managed geriatric PHF. Methods: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample was queried from 2012 to 2015. Geriatric patients with PHF were identified and those who underwent operative or non-operative management were compared in trends, outcomes and costs. Results: In total, 137 810 patients met inclusion criteria, of which 51 795 (37.6%) underwent operative management. The operative cohort was younger (76.6 vs 80.9, p<0.001) with a greater proportion of females (81.8% vs 77.6%, p<0.001). The operative cohort demonstrated less frailty and lower Elixhauser Comorbidity Scores (both p<0.001). The operative cohort was also more likely to be discharged home (30.4% vs 13.9%, p<0.001). There was no significant linear trend in age-adjusted and sex-adjusted proportions of operative versus non-operative geriatric PHF (p=0.071), but a positive linear trend was statistically significant for total cost of operative geriatric PHF (p<0.001). Multivariable analyses demonstrated similar overall complication rates between cohorts (OR 0.95, 95% CI 0.89 to 1.00; p=0.06), although surgical intervention increased length of stay (LOS) by 0.15 days (95% CI 0.03 to 0.27; p<0.001) and median cost of hospitalization by US$10 684 (95% CI US$10 384 to US$10 984; p<0.001). Conclusions: This study identifies a positive linear trend in total cost of operatively managed geriatric PHF from 2012 to 2015. Operative management of geriatric PHF is associated with a similar overall complication rate and greater likelihood of being discharged home. Although non-operative management is associated with decreased LOS and hospital expenses, providers should consider surgical PHF treatment options when available and appropriate in the context of patient-focused outcomes, particularly long-term disposition after intervention. Level of Evidence: This level IV retrospective study identifies.

The rising incidence of ductal adenocarcinoma and intraductal carcinoma of the prostate: Diagnostic accuracy of biopsy, MRI-visibility, and outcomes.

INTRODUCTION: Ductal adenocarcinoma (DA) and intraductal carcinoma (IDC) of the prostate are associated with higher stage disease at radical prostatectomy (RP). We evaluated diagnostic accuracy of biopsy, MRI-visibility, and outcomes for patients undergoing RP with DA/IDC histology compared to pure acinar adenocarcinoma (AA) of the prostate. MATERIALS AND METHODS: A retrospective cohort study of men receiving RP between 2014 and 2021 revealing AA, DA, or IDC on final pathology was conducted. Multivariable logistic regression and Cox proportional hazards regression models were employed. RESULTS: A total of 609 patients were included with 103 found to have DA/IDC. Patients with DA/IDC were older and had higher PSA, biopsy grade group (GG), RP GG, and other pathologic findings (extraprostatic extension, lymphovascular invasion, perineural invasion, pN stage) compared to AA patients (all P < 0.05). On multivariable analysis, higher age, RP GG, and pT3a were associated with DA/IDC on RP (all P < 0.05). Sensitivity and specificity of biopsy compared to RP for diagnosis of DA/IDC was 29.1% (16.7% DA, 27.8% IDC) and 96.6% (99.3% DA, 96.6% IDC), respectively. In a subset of 281 men receiving MRI, PI-RADS distribution was similar for patients with DA/IDC vs. AA (90.7% vs. 80.7% with PI-RADS 4-5 lesions, P = 0.23) with slightly higher biopsy sensitivity (41.9%). DA/IDC was associated with worse BCR (HR = 1.77, P = 0.02) but not biopsy DA/IDC (P = 0.90). CONCLUSIONS: Sensitivity of prostate biopsy was low for detection of DA/IDC histology at RP. Patients with DA/IDC histology had unfavorable pathologic features at RP and worse BCR. Of patients with DA/IDC at RP, 90.7% were categorized as PI-RADS 4 to 5 on preoperative MRI.

Clinical outcomes and dosimetric predictors of toxicity for re-irradiation of vaginal recurrence of endometrial cancer.

OBJECTIVE: To report clinical outcomes and dosimetric predictors of late toxicity for patients with vaginal recurrence of endometrial cancer treated with brachytherapy in the re-irradiation setting. METHODS: On retrospective review, 32 patients with vaginal recurrence of endometrial cancer received salvage brachytherapy with or without pelvic radiotherapy (RT) from 06/2003-12/2017. Prior RT modalities were vaginal brachytherapy (19, 59%), pelvic RT (7, 22%) or both (6, 19%). Image-guided brachytherapy was performed with CT- (25, 78%) or MR-guidance (7, 22%). Vaginal control, recurrence-free survival (RFS) and overall survival (OS) were estimated by Kaplan-Meier method. Late toxicity was graded by Common Toxicity Criteria for Adverse Events. RESULTS: Median time from prior RT to re-irradiation was 22 months (range, 4-140). Salvage RT modalities were pelvic RT and brachytherapy (25, 78%) or brachytherapy alone (7, 22%). With median follow-up of 47 months, 3/5-year vaginal control, RFS and OS rates were 64/56%, 47/41% and 68/42%, respectively. Six patients (19%) had no evidence of disease at 85-155 months. Late grade 2/3 GI, GU and vaginal toxicity rates were 13%/16%, 19%/13%, and 9%/16%. Cumulative D2cc rectum (sum of prior and salvage RT courses) was predictive of grade 2+ and grade 3 GI toxicity. Cumulative D2cc rectum for an estimated 10% risk of late grade 2+ and 3 GI toxicity was 86 Gy and 92 Gy, respectively. CONCLUSIONS: Salvage image-guided brachytherapy in the re-irradiation setting results in modest local control and increased late toxicity for localized recurrent endometrial cancer. With long-term disease control, cumulative D2cc rectum may be used to reduce late GI complication risk.

MicroRNA profiling in a case-control study of African American women with uterine serous carcinoma.

OBJECTIVE: Uterine serous carcinoma (USC) is an aggressive subtype of endometrial cancer associated with worse survival outcomes in African American (AA) patients. This study evaluated tumor miRNA expression by race, clinical and tumor characteristics, and survival outcomes. METHODS: FFPE tumor tissue from hysterectomy specimens was identified for 29 AA cases. Case matching was performed by computer-based random assignment in a 1:1 ratio with Caucasian controls based on age, stage and histologic subtype (pure vs. mixed). RNA was extracted from 77 specimens (54 tumors and 23 matched normal endometrium). MicroRNA array profiling was performed by microRNA Hi-Power Labeling (Hy3/Hy5) and hybridization to miRCURY LNA microRNA Array 7th Gen. RESULTS: Clinical and treatment characteristics were similar for cases and controls, although use of adjuvant radiation was less common in African Americans (p = 0.03). Of 968 miRNAs analyzed, 649 were differentially expressed in normal endometrium vs. tumor. When compared by race, histologic subtype, stage or presence of LVI, no differentially expressed miRNAs were identified. In patients with disease recurrence at 3 years, the three most upregulated miRNAs were miR-1, miR-21-5p and miR-223. Of these, increased miR-223 expression (>median) was associated with worse OS (p = 0.0496) in an independent dataset (TCGA dataset) comprising of 140 patients with USC (mixed or pure serous). After adjusting for age, ethnicity and BMI, upregulation of miR-223 remained risk factor for death (adjusted HR 2.87, 95% CI 1.00-8.27). CONCLUSIONS: MiRNA profiling did not identify biological differences between AA and Caucasian patients with USC. Upregulation of miR-223 may be a prognostic factor in USC.

Adjuvant Radiation Field Extent and Sites of Failure in Node Positive Endometrioid Endometrial Cancer.

PURPOSE: In patients with node-positive endometrial cancer, adjuvant radiation therapy with chemotherapy decreases local-regional recurrence compared with chemotherapy alone. However, the optimal radiation field borders and extent of nodal coverage have not been well studied. In a multi-institutional cohort, survival outcomes and sites of failure were analyzed for patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IIIC endometrioid endometrial cancer treated with pelvic radiation therapy (PRT) versus extended-field radiation therapy (EFRT), which encompassed high para-aortic lymph nodes. METHODS AND MATERIALS: In a multi-institutional retrospective study, 143 patients with FIGO stage IIIC1 or IIIC2 endometrioid endometrial cancer treated with adjuvant radiation therapy from 2000 to 2016 were identified. Patient subgroups were classified by substage and radiation field extent: stage IIIC1 received EFRT, stage IIIC1 received PRT, and stage IIIC2 received EFRT. Recurrence-free survival (RFS), overall survival (OS), and out-of-field recurrence were calculated by the Kaplan-Meier method. Multivariate analysis was performed using the Cox proportional hazards model. Sites of failure were categorized as within or outside the radiation field. RESULTS: The median follow-up was 59 months; 87% of patients received chemotherapy. The 5-year RFS and OS rates were 73% and 87%, respectively. By subgroup, 5-year RFS rates were 79% for stage IIIC1 EFRT, 73% for stage IIIC1 PRT, and 69% for stage IIIC2 EFRT (P = .4). On multivariate analysis, the recurrence risk was highest for stage IIIC2 EFRT, although this result was not statistically significant (adjusted hazard ratio, 2.0; P = .4). In-field vaginal and nodal recurrences were observed in 2 patients (1%) and 4 patients (3%), respectively. Of 78 patients with stage IIIC1 cancer treated with PRT, 5 (6%) had isolated para-aortic nodal relapse outside the radiation field; 3 were long-term survivors (more than 6 years after salvage therapy). For patients with para-aortic recurrence, 86% had lymphovascular invasion, 71% had myometrial invasion of ≥50%, and 57% had grade 3 disease. CONCLUSIONS: Adjuvant chemoradiation therapy resulted in excellent survival outcomes for patients with FIGO stage IIIC endometrioid endometrial cancer. For patients with positive pelvic nodes, isolated para-aortic relapse outside the PRT field was uncommon and amenable to salvage therapy.

Definitive radiotherapy for vaginal recurrence of early-stage endometrial cancer: survival outcomes and effect of mismatch repair status.

OBJECTIVE: To evaluate clinical outcomes, prognostic factors, and toxicity in patients with vaginal recurrence of early-stage endometrial cancer treated with definitive radiotherapy. METHODS: Retrospective review identified 62 patients with stage I-II endometrial cancer and vaginal recurrence treated with external beam radiotherapy and image-guided brachytherapy with definitive intent from November 2004 to July 2017. All patients had prior hysterectomy without adjuvant radiotherapy and >3 months follow-up. Mismatch repair (MMR) status was determined by immunohistochemical staining of the four mismatch repair proteins (MLH1, MSH2, PMS2, and MSH6) when available in the pathology record. Rates of vaginal control, recurrence-free survival, and overall survival were calculated by Kaplan-Meier. Univariate and multivariate analyses were performed by Cox proportional hazards. RESULTS: Most patients had endometrioid histology (55, 89%), grade 1 or 2 tumor (53, 85%), and vaginal-only recurrence (55, 89%). With a median follow-up of 39 months (range, 3-167), 3- and 5-year rates of vaginal control, recurrence-free survival, and overall survival were 86% and 82%, 69% and 55%, and 80% and 61%, respectively. On multivariate analysis, non-endometrioid histology (HR 12.5, P<0.01) was associated with relapse when adjusted for chemotherapy use. Patients with non-endometrioid histology also had a 4.5-fold higher risk of death when adjusted for age (P=0.02). Twenty patients had known MMR status, all with grade 1-2 endometrioid tumors and 10 (50%) with MMR deficiency. The 3-year recurrence-free survival was 100% for MMR-proficient tumors and 52% for MMR-deficient (P=0.03). Late grade 2 and 3 gastrointestinal, genitourinary and vaginal toxicity was reported in 27% and 3%, 15% and 2%, and 16% and 2% of patients, respectively. CONCLUSION: Definitive radiotherapy with image-guided brachytherapy resulted in 5-year local control rates exceeding 80% and late severe toxicity rates were under 3%. Distant recurrence was common and highest for those with grade 3 or non-endometrioid tumors and MMR deficient grade 1-2 disease.

Low-dose adjuvant vaginal cylinder brachytherapy for early-stage non-endometrioid endometrial cancer: recurrence risk and survival outcomes.

OBJECTIVE: The aim of this study was to evaluate recurrence patterns and survival outcomes for patients with early-stage non-endometrioid endometrial adenocarcinoma treated with adjuvant high-dose rate vaginal brachytherapy with a low-dose scheme. METHODS: A retrospective review was performed of patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II non-endometrioid endometrial cancer who received adjuvant vaginal brachytherapy with a low-dose regimen of 24 Gy in six fractions from November 2005 to May 2017. All patients had >6 months of follow-up. Rates of recurrence-free survival, overall survival, vaginal, pelvic, and distant recurrence were calculated by the Kaplan-Meier method. Prognostic factors for recurrence and survival were evaluated by Cox proportional hazards modeling. RESULTS: A total of 106 patients were analyzed. Median follow-up was 49 months (range 9-119). Histologic subtypes were serous (47%, n=50), clear cell (10%, n=11), mixed (27%, n=29), and carcinosarcoma (15%, n=16). Most patients (79%) had stage IA disease, 94% had surgical nodal assessment, and 13% had lymphovascular invasion. Adjuvant chemotherapy was delivered to 75%. The 5-year recurrence-free and overall survival rates were 74% and 83%, respectively. By histology, 5-year recurrence-free/overall survival rates were: serous 73%/78%, clear cell 68%/88%, mixed 88%/100%, and carcinosarcoma 56%/60% (p=0.046 and p<0.01). On multivariate analysis, lymphovascular invasion was significantly associated with recurrence (HR 3.3, p<0.01). The 5-year vaginal, pelvic, and distant recurrence rates were 7%, 8%, and 21%, respectively. Vaginal and pelvic recurrence rates were highest for patients with carcinosarcoma, lymphovascular invasion and/or FIGO stage IB/II disease. At 5 years, vaginal and pelvic recurrence rates for patients with lymphovascular invasion were 33% and 40%, respectively. Patients with stage IA disease or no lymphovascular invasion had 5-year vaginal recurrence rates of 4% and pelvic recurrence rates of 6% and 3%, respectively. CONCLUSIONS: Adjuvant high-dose rate brachytherapy with a low-dose scheme is effective for most patients with early-stage non-endometrioid endometrial cancer, particularly stage IA disease and no lymphovascular invasion. Pelvic radiation therapy should be considered for those with carcinosarcoma, lymphovascular invasion and/or stage IB/II disease.

Vaginal recurrence of endometrial cancer: MRI characteristics and correlation with patient outcome after salvage radiation therapy.

PURPOSE: To evaluate MRI characteristics in vaginal recurrence of endometrial cancer (EC) including tumor volume shrinkage during salvage radiotherapy, and to identify imaging features associated with survival. METHODS: Patients with vaginal recurrence of EC treated with external beam radiotherapy (EBRT) followed by brachytherapy (BT), and with available pelvic MRI at two time points: baseline and/or before BT were retrospectively identified from 2004 to 2017. MRI features including recurrence location and tissue characteristics on T2- and T1-weighted images were evaluated at baseline only. Tumor volumes were measured both at baseline and pre-BT. Survival rates and associations were evaluated by Cox regression and Fisher's exact test, respectively. RESULTS: Sixty-two patients with 36 baseline and 50 pre-BT pelvic MRIs were included (24/62 with both MRIs). Vaginal recurrence of EC was most commonly located in the vaginal apex (27/36, 75%). Tumors with a post-contrast enhancing peripheral rim or low T2 signal rim at baseline showed longer recurrence-free survival (RFS) (HR 0.2, 95% CI 0.1-0.9, P < 0.05 adjusted for histology; HR 0.2, 95% CI 0.1-0.8, P < 0.05, respectively). The median tumor shrinkage at pre-BT was 69% (range 1-99%). Neither absolute tumor volumes nor volume regression at pre-BT were associated with RFS. Lymphovascular space invasion (LVSI) at hysterectomy and adjuvant RT were associated with recurrence involving the distal vagina (both P < 0.05). CONCLUSION: Vaginal recurrences with rim enhancement at baseline MRI predicted improved RFS, while tumor volume shrinkage at pre-BT did not. Distal vaginal recurrence was more common in patients with LVSI and adjuvant RT at EC diagnosis.

Low-Dose Adjuvant Cylinder Brachytherapy for Endometrioid Endometrial Cancer.

PURPOSE: Our purpose was to evaluate outcomes and sites of failure for women with early stage endometrial adenocarcinoma treated with adjuvant high-dose-rate (HDR) vaginal brachytherapy (VB) with a low dose scheme. METHODS AND MATERIALS: Retrospective review identified 318 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II endometrioid endometrial cancer who received adjuvant HDR VB to a dose of 24 Gray (Gy) in 6 fractions from 2005 to 2017. Patients with <6 months follow-up were excluded. Dose was prescribed to cylinder surface and computerized tomography (CT) imaging was performed before each fraction to assess cylinder placement. Rates of vaginal relapse (VR), pelvic nodal relapse, distant metastasis, recurrence-free survival, and overall survival were calculated by Kaplan-Meier method. Univariate analysis was performed by log rank test or Cox proportional hazards. Pretreatment CT images were analyzed for patients with VR. RESULTS: Median follow-up was 42 months for 243 patients. The 3-year rates of VR, pelvic nodal relapse, distant metastasis, recurrence-free survival, and overall survival were 1.9%, 1.5%, 4.3%, 94.1%, and 98.9%, respectively. The 3-year VR rates by Gynecologic Oncology (GOG)-99 risk groups were 0%, 1.4%, and 3.2% for low risk, low-intermediate risk, and high-intermediate risk (HIR) disease (P = .5). By Post-operative Radiation Therapy in Endometrial Carcinoma (PORTEC) risk stratification, 3-year VR rate was 1.3% for HIR disease. On review of pretreatment CT images of the 6 patients with VR, 3 patients had relapse at the introitus outside of the treated vaginal length, and 3 had in-field recurrence at the vaginal apex. Higher body mass index (BMI) was associated with VR, with a 14% increase in risk per BMI unit (kg/m2, P = .02). There were no reported grade 2 GI or any grade 3 toxicities. CONCLUSIONS: Adjuvant HDR VB with a low-dose regimen results in excellent clinical outcomes for patients with early stage endometrioid endometrial cancer. Patients with higher BMI may be at increased risk of VR, and additional study is needed to optimize brachytherapy treatment parameters.

Salvage radiation therapy for localized recurrent ovarian cancer.

INTRODUCTION: To evaluate clinical outcomes for patients with localized recurrent ovarian cancer treated with salvage radiotherapy. METHODS: In a retrospective single institutional analysis, we identified 40 patients who received salvage radiotherapy for localized ovarian cancer recurrence from January 1995 to June 2011. Recurrent disease was categorized as: pelvic peritoneal (45%, 18), extraperitoneal/nodal (35%, 14), or vaginal (20%, eight). Actuarial disease-free and overall survival estimates were calculated by Kaplan-Meier and prognostic factors evaluated by the Cox proportional hazards model. RESULTS: Median follow-up was 42 months. Median patient age was 54 years (range, 27-78). Histologic subtypes were: serous (58%, 23), endometrioid (15%, six), clear cell (13%, five), mucinous (8%, three), and other (8%, three). At the time of salvage radiotherapy, surgical cytoreduction was performed in 60% (24) and 68% (27) had platinum-sensitive disease. Most patients (63%, 25) received salvage radiotherapy at the time of first recurrence. Relapse after salvage radiotherapy occurred in 29 patients at a median time of 16 months and was outside the radiotherapy field in 62%. 18 At 3 years, disease-free and overall survival rates were 18% and 80%, respectively. On multivariate analysis, non-serous histology (hazards ratio 0.3, 95% CI 0.1-0.7) and platinum-sensitivity (hazards ratio 0.2, 95% CI 0.1-0.5) were associated with lower relapse risk. Platinum-sensitivity was also associated with overall survival (hazards ratio 0.4, 95% CI 0.1-1.0). Four patients (10%) were long-term survivors without recurrence 5 years after salvage radiotherapy. Of the five patients with clear cell histology, none experienced relapse at the time of last follow-up. DISCUSSION: Patients with non-serous and/or platinum-sensitive ovarian cancer had the greatest benefit from salvage radiotherapy for localized recurrent disease. Although relapse was common, radiotherapy prolonged recurrence for > 1 year in most patients and four were long-term survivors.

Engaging women with an embodied conversational agent to deliver mindfulness and lifestyle recommendations: A feasibility randomized control trial.

OBJECTIVE: This randomized controlled trial evaluates the feasibility of using an Embodied Conversational Agent (ECA) to teach lifestyle modifications to urban women. METHODS: Women were randomized to either 1) an ECA (content included: mindfulness, stress management, physical activity, and healthy eating) or 2) patient education sheets mirroring same content plus a meditation CD/MP3 once a day for one month. General outcome measures included: number of stress management techniques used, physical activity levels, and eating patterns. RESULTS: Sixty-one women ages 18 to 50 were enrolled. On average, 51% identified as white, 26% as black, 23% as other races; and 20% as Hispanic. The major stress management techniques reported at baseline were: exercise (69%), listening to music (70%), and social support (66%). After one month, women randomized to the ECA significantly decreased alcohol consumption to reduce stress (p=0.03) and increased daily fruit consumption by an average of 2 servings compared to the control (p=0.04). CONCLUSION: It is feasible to use an ECA to promote health behaviors on stress management and healthy eating among diverse urban women. PRACTICE IMPLICATIONS: Compared to patient information sheets, ECAs provide promise as a way to teach healthy lifestyle behaviors to diverse urban women.

Limited adoption of current guidelines for clinical breast examination by primary care physician educators.

BACKGROUND: In 2004, the CDC and the American Cancer Society (ACS) published performance guidelines recommending a validated method of clinical breast exams (CBE) using the vertical strips method (VSM) along with other key exam components. We examined the use of the VSM by academic medicine physicians and identified predictor variables for its adoption. METHODS: Clinician educators in the Society of General Internal Medicine (SGIM) and physicians in the Society of Teachers of Family Medicine (STFM) were administered web-based surveys on CBE practices in 2009. RESULTS: A total of 1,772 (42%) physicians responded. Only 40% of respondents reported using the VSM, compared with 53% using the circular search method. Variables and their odds ratios (ORs) associated with an increase adoption of the VSM were having a primary teaching hospital affiliation (OR 1.4 [1.1, 1.9]), having taken a course on breast health or breast cancer in the past 5 years (OR 1.5 [1.1, 2.0]), and having completed residency in the past 5 years (OR 2.3 [1.6, 3.4]) and/or 10-15 years (OR 1.6 [1.2, 2.2]) compared to more than 15 years. The extent of teaching responsibilities was not associated with adoption of the VSM. CONCLUSIONS: A majority of physician responders highly involved in education of students and residents continue to practice methods of CBE that do not reflect the current guidelines. Faculty development and training on updated CBE practices may accelerate adoption of guideline-recommended care.

Breast and Prostate Cancer Patient Perspectives and Perceptions of Interprofessional Collaboration during Cancer Treatment: A Pilot Study.

PURPOSE: Interprofessional collaboration (IPC) in radiation oncology is inherent in the care of the cancer patient. Breast and prostate cancer patients encounter a number of health care providers during their cancer diagnosis, treatment and follow up. As the complexity of cancer treatment increases, patients are seen by interprofessional teams of specialists. These include surgeons, medical oncologists, radiation oncologists, radiation therapists, nurses, dietitians, pharmacists, and other professionals from multiple support services. There is a gap in the literature regarding the cancer patients' perspectives and perceptions of how these different professions collaborate and contribute to their cancer journeys. The purpose of this study was to explore patient perspectives and perceptions of interprofessional collaboration that were taking place at the Odette Cancer Centre at Sunnybrook Health Sciences Centre at Toronto, Ontario, Canada. METHODS: Twenty-three patients with breast (n = 11/23) and prostate (n = 12/23) cancer were identified as being eligible to participate in the study during December 2012 to February 2013. Breast cancer patients (BCPs) and prostate cancer patients (PCPs) were invited to participate during their consultation, planning, or follow-up appointments. After a minimum of 2 weeks of treatment, they were asked to complete a survey exploring their perspectives and perceptions regarding IPC during their cancer care. Simple, descriptive statistics were performed, including percentages of Likert scale ratings. An open-ended question was included and reviewed by the team of investigators for common emerging themes. RESULTS: In terms of patient perspective, all surveyed patients (100%) reported IPC among different health care professions was important to them. The majority of patients (91% of BCPs and 100% of PCPs) agreed IPC resulted in better patient care. The largest variation in results was seen in the statement regarding IPC resulting in less repeated information patients have to provide, with 92% of PCPs agreeing and only 55% of BCPs agreeing. In terms of patient perception, IPC at the Odette Cancer Centre was generally assessed positively. The majority of patients (100% of BCPs and 84% of PCPs) agreed that the health care professions worked well as a team. 64% of BCPs and 100% of PCPs reported the health care professionals communicated well with each other. Most patients (82% of BCPs and 92% of PCPs) reported feeling part of the health care team. CONCLUSION: IPC was found to be important to the majority of respondents. Patient experiences were almost uniformly positive with radiation therapists, radiation oncologists, and radiation nurses. An unexpected outcome of 37% of BCPs did not agree that repeating health information to multiple health care professionals was negative to their care.
