Exploring the Relationship Between Health-Illness Transition Experiences and Distress Among Patients With Pancreatic Cancer.

OBJECTIVES: To explore the correlation between health-illness transition (HIT) experiences and distress among patients with pancreatic cancer. SAMPLE & SETTING: 55 patients with a diagnosis of pancreatic cancer receiving chemotherapy at a tertiary cancer center in New York. METHODS & VARIABLES: A prospective correlational study was performed to explore the frequency, extent, and management of HITs. HITs were evaluated using the Measurement of Transitions in Cancer Scale, and distress was measured with the National Comprehensive Cancer Network Distress Thermometer. RESULTS: All patients experienced at least one HIT. The extent of HITs decreased over time. Patients reported that they managed HITs moderately well. There was a significant correlation between unmanaged HITs and distress. As distress increased, the extent of the physical and emotional HITs increased and management worsened. IMPLICATIONS FOR NURSING: HITs are ubiquitous among patients diagnosed with pancreatic cancer. Associated distress inhibits management. Nurses are well suited to assess for potential HITs and to support self-management of HITs.

The Acknowledge-Normalize-Partner (ANP) Framework: A novel empathic communication tool for oncology nurses.

OBJECTIVE: To describe the development and implementation of a novel tool designed to enhance nurse-patient communication in a major academic cancer center, which nurses can learn quickly, incorporate into their primary palliative care practice, and broadly disseminate in order to improve the patient experience. METHOD: An evidence-based empathic communication tool and educational program were designed to provide essential skills to oncology nurses in having discussions with patients about their personal values. Evaluation included nurse focus groups, pre- and post-course evaluations and interviews, and patient questionnaires. RESULTS: Nurses were satisfied with the educational program and found the communication tool effective in a variety of clinical situations including discussions about personal values. Patients reported increased occurrences of these discussions when nurses utilized the framework (97% vs. 58%, p < 0.0001) and a higher quality of clinician communication (mean [SD] from 0 = very worst to 10 = very best: 7.18 [2.3] vs. 5.04 [2.9], p = 0.001). SIGNIFICANCE OF RESULTS: Skilled, empathic communication is an essential component of high-quality primary palliative care. Oncology nurses are well suited to lead communication and provide this care as part of an interprofessional team. The training and tool described here are targeted and efficient, and prepare nurses to respond skillfully to emotion while facilitating important discussions about patient values.

Beyond 9 to 5: Expansion of an Inpatient Specialist Palliative Care Service to 24/7 Onsite Presence.

For seriously ill hospitalized patients with a diagnosis of cancer, there exists a need for specialist palliative care, 24 hours a day, 7 days a week. This article describes the expansion of a palliative care consult service in a metropolitan, dedicated cancer hospital to provide 24/7 specialist palliative care including onsite overnight presence by advanced practice registered nurses and to evaluate the impact of this change on nighttime utilization of the consult service. Inpatient management encounters and outpatient calls were compared before and after the expansion. The onsite availability of a palliative care specialist between midnight and 8 am increased from less than 10% of the time in 2019 to 100% of the time in 2021. The number of inpatient overnight calls and pages increased from a median of 4 to 16, and the number of follow-up visits evaluated increased from a median of 0 to 6. However, the number of overnight palliative care consults and outpatient calls evaluated did not change significantly. Expansion of a hospital-based palliative care service to include 24/7 onsite overnight presence increased patient, family, and night staff access to high-quality palliative care, prompt symptom management, and staff coaching on primary palliative care skills.

Recognizing spiritual injury in cancer: A case study.

BACKGROUND: Spiritual distress is a common symptom among patients with cancer. Spiritual injury (SI), a type of spiritual distress, occurs when there is a breakdown in the relationship between the individual and their higher power. Patients who experience spiritual injury may have poor health outcomes. METHODS: A case report of a woman with stage IV non-small cell lung cancer who had experienced a SI. RESULTS: The palliative care team, in collaboration with the palliative care chaplain, was able to recognize that the patient had experienced a SI. They were able to help the patient to process and reflect upon this experience and ultimately treat her suffering. SIGNIFICANCE OF RESULTS: All palliative care providers should assess their patients' spiritual health and monitor for the existence of SI.

Three-Year Nursing PhD Model Recommendations from the RWJF Future of Nursing Scholars.

BACKGROUND: In response to the 2011 Future of Nursing report, the Robert Wood Johnson Foundation created the Future of Nursing Scholars (FNS) Program in partnership with select schools of nursing to increase the number of PhD-prepared nurses using a 3-year curriculum. METHOD: A group of scholars and FNS administrative leaders reflect on lessons learned for stakeholders planning to pursue a 3-year PhD model using personal experiences and extant literature. RESULTS: Several factors should be considered prior to engaging in a 3-year PhD timeline, including mentorship, data collection approaches, methodological choices, and the need to balance multiple personal and professional loyalties. Considerations, strategies, and recommendations are provided for schools of nursing, faculty, mentors, and students. CONCLUSION: The recommendations provided add to a growing body of knowledge that will create a foundation for understanding what factors constitute "success" for both PhD programs and students.

Illness Understanding, Prognostic Awareness, and End-of-Life Care in Patients With GI Cancer and Malignant Bowel Obstruction With Drainage Percutaneous Endoscopic Gastrostomy.

PURPOSE: Malignant bowel obstruction (MBO) is common in advanced GI cancer, and MBO management, including drainage percutaneous endoscopic gastrostomy (dPEG), is palliative. How patients understand the goals of dPEG and its impact on disease is inadequately understood in the literature. Therefore, we analyzed these issues in patients with GI cancer. METHODS: Demographics, clinical variables, and patient outcomes were abstracted from the medical record. Illness understanding and future expectations were retrieved from palliative care notes. We described additional treatment and outcomes after dPEG and estimated overall survival (OS). RESULTS: From January 2015 to June 2017, 125 admitted patients with metastatic GI cancer underwent dPEG for MBO. Cancers were most commonly colorectal (34%) and pancreatic/ampullary (25%). During the dPEG admission, 32% (40 of 125) of patients had a palliative care consultation, and 22% (28 of 125) were asked about illness understanding and future expectations. All (28 of 28) reported good understanding of the advanced nature of their disease, but few were accurate about prognosis given their stage IV disease (10 of 28). Of the 117 (94%) discharged, 13% (15 of 117) received additional chemotherapy, which rarely prevented progression; half (63 of 117) had a do-not-resuscitate order; and most (101 of 117) were enrolled in hospice at death. Median time to death was 37 days (95% CI, 29 to 45 days); 6-month OS was 3.7% (95% CI, 1.2% to 8.4%). CONCLUSION: dPEGs are placed close to end of life in patients with advanced GI cancer. A minority of patients receive additional chemotherapy post-dPEG. Many have adequate disease understanding, but chemotherapy benefit is low, and future expectations vary. This may be an opportunity for improved communication regarding palliative procedures in advanced cancer.

Outcomes of ICU Admission of Patients With Progressive Metastatic Gastrointestinal Cancer.

BACKGROUND: Data on the outcomes of intensive care unit (ICU) admissions for patients with advanced incurable chemoresistant solid tumor malignancies, and the benefits of subsequent/post-ICU anticancer treatments are limited but have end-of-life and ethical implications. METHODS: An institutional database was queried to identify patients of the gastrointestinal (GI) medical oncology service of Memorial Sloan Kettering Cancer Center with ≥1 ICU admission during 2014. Records were reviewed for evidence of cancer control from cancer treatment after the ICU admission. RESULTS: Twenty-eight patients who had progressed beyond at least first-line chemotherapy for metastatic GI adenocarcinoma were admitted to the ICU for sequelae of progressive clinical deterioration. The most frequent reasons for ICU admission were sepsis (39%) and acute respiratory failure (29%). Ten patients died in the ICU, 3 died during the same hospitalization after ICU discharge, and 15 were discharged from the hospital. Of these 15, the median survival from hospital discharge was 2.2 months and 6 received further chemotherapy but with no evidence of clinical benefit. Of these 6, 3 lived over 5 months but the treatment of 5 entailed recycling of previously ineffective chemotherapy agents (3) or those originally used in the adjuvant setting (2). Two of these patients received liver-directed therapy without benefit. CONCLUSIONS: Admissions to the ICU in this cancer population were associated with high morbidity and mortality and did not result in benefit from subsequent cancer treatment. These data can be used to help establish realistic expectations and care goals in previously treated patients having metastatic GI cancer with clinical deterioration.

Self-Management Interventions for Psychological Distress in Adult Cancer Patients: A Systematic Review.

Psychological distress is prevalent among cancer patients, who may be vulnerable to distress at times of transition, such as a change in symptom experience, employment, or goal of treatment. Independently, both psychological distress and transitions impair patients' quality of life, and together their adverse impact may be intensified. Self-management allows patients to engage in tasks that influence the disease experience and can include strategies to help mitigate distress associated with transitions. The purpose of this systematic review was to examine research on the relationship between self-management interventions and distress in adult cancer patients receiving active tumor-directed therapy. From a search of seven electronic databases, 5,156 articles were identified; however, nine studies met inclusion criteria. Our review suggested that self-management interventions may help address psychological distress in patients receiving cancer treatment but that the current evidence is not robust enough to support a definitive conclusion.

Giving Voice to Patient Values Throughout Cancer: A Novel Nurse-Led Intervention.

CONTEXT: Optimal advance care planning allows patients to articulate their values as a touchstone for medical decision making. Ideally, this occurs when patients are clinically stable, and with opportunities for iteration as the clinical situation unfolds. OBJECTIVES: Testing feasibility and acceptability in busy outpatient oncology clinics of a novel program of systematic, oncology nurse-led values discussions with all new cancer patients. METHODS: Within an institutional initiative integrating primary and specialist palliative care from diagnosis for all cancer patients, oncology nurses were trained to use specific questions and an empathic communication framework to discuss health-related values during outpatient clinic visits. Nurses summarized discussions on a template for patient verification, oncologist review, and electronic medical record documentation. Summaries were reviewed with the patient at least quarterly. Feasibility and acceptability were evaluated in three clinics for patients with hematologic or gastrointestinal malignancies. RESULTS: Oncology nurses conducted 177 total discussions with 67 newly diagnosed cancer patients (17 with hematologic and 50 with gastrointestinal malignancies) over two years. No patient declined participation. Discussions averaged eight minutes, and all patients verified values summaries. Clinic patient volume was maintained. Of 31 patients surveyed, 30 (97%) reported feeling comfortable with the process, considered it helpful, and would recommend it to others. Clinicians strongly endorsed the values discussion process. CONCLUSION: Nurse-led discussions of patient values soon after diagnosis are feasible and acceptable in busy oncology clinics. Further research will evaluate the impact of this novel approach on additional patient-oriented outcomes after broader dissemination of this initiative throughout our institution.

1-2-3 Project: A Quality Improvement Initiative to Normalize and Systematize Palliative Care for All Patients With Cancer in the Outpatient Clinic Setting.

BACKGROUND: Prior work to integrate early palliative care in oncology has focused on patients with advanced cancer and primarily on palliative care consultation. We developed this outpatient clinic initiative for newly diagnosed patients at any stage, emphasizing primary (nonspecialist) palliative care by oncology teams, with enhanced access to palliative care specialists. METHODS: We piloted the project in two medical oncology specialty clinics (for patients with myelodysplastic syndrome and GI cancer, respectively) to establish feasibility. On a visit-based schedule, patients systematically reported symptoms, information/decision-making preferences, and illness understanding. They also participated in discussions of their core values with their oncology nurse. Oncology teams were first responders to palliative care needs, whereas specialists were available for clinician support and direct patient consultation. RESULTS: All 58 eligible patients were enrolled. In both clinics, patient self-reports documented a heavy symptom burden. Information/decision-making preferences and illness understanding levels varied across patients. Patients prepared new advance directives. Oncology nurses documented discussions of core values. Requests for palliative care consultation decreased over time as oncology teams embraced their primary palliative care role with coaching from the specialists. Clinic workflow and patient volume were maintained. CONCLUSION: Our pilot experience suggests that in outpatient oncology clinics, a structured, scheduled, and systematic approach is feasible to deliver palliative care to newly diagnosed patients with cancer at any stage and throughout their illness trajectory. This novel approach identified important, actionable palliative care needs, relying primarily on oncology teams to respond to these needs, while enhancing access to palliative care specialist input. Expansion to additional clinics will allow evaluation of scalability and generalizability, along with measurement of a broader range of important outcomes.

Nursing Education: Review of Assessment, Clinical Care, and Implications for Practice Regarding Older Adult Patients With Cancer.

BACKGROUND: As the population of older adults continues to increase, the healthcare system must adapt to respond to their unique and complicated health needs. More than half of all patients diagnosed with cancer in America are aged 65 years or older. The appropriate care for older adult patients with cancer requires a holistic approach with careful coordination of interprofessional providers. OBJECTIVES: This article aims to describe the components of the comprehensive geriatric assessment, summarize the importance of exercise in older adults, discuss the harms of polypharmacy, and evaluate the initiatives to improve geriatric nursing education. METHODS: The literature was reviewed and summarized to provide information on comprehensive geriatric assessment, exercise, polypharmacy, and geriatric nursing education. FINDINGS: Numerous assessment tools can help guide the care of older adult patients with cancer. Because many nurses have little formal geriatric-specific training, there is a growing need for targeted education to ensure best practices.

Morbidity of sentinel node biopsy: relationship between number of excised lymph nodes and patient perceptions of lymphedema.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is associated with reduced morbidity, although lymphedema remains a significant complication. Previously, we found no association between number of excised lymph nodes (LNs) and measured lymphedema in SLNB patients. In this analysis, we examined the relationship between number of LNs excised during SLNB and patient-perceived lymphedema. METHODS: A total of 600 women who underwent SLNB for breast cancer were prospectively studied. Measured lymphedema was evaluated by circumferential bilateral upper-extremity measurements taken preoperatively and 3-8 years postoperatively. Patient-perceived lymphedema was evaluated by interview at follow-up. The relationship between lymphedema, total LNs excised, and clinicopathologic variables was assessed with Fisher's exact test, Wilcoxon rank-sum test, kappa statistic, and McNemar's test. RESULTS: At a median of 5 years, 18 (3%) patients reported perceived lymphedema. More LNs were excised in patients with perceived lymphedema compared with those without (median, 5.5 vs. 3; p = 0.01). Only 6 of 18 women with perceived lymphedema had objectively measured lymphedema (kappa = 0.22). Patients with numbness more likely reported perceived lymphedema (p = 0.03) and had more LNs excised (p = 0.02). Women with surgery on the nondominant axilla were less likely to perceive arm swelling, regardless of the presence of measured lymphedema. CONCLUSIONS: After SLNB alone, patient-perceived lymphedema is uncommon, but its prevalence increases with more LNs excised. There is poor agreement between patient perceptions and objective measures. Our data suggest that factors other than limb enlargement, such as sensory nerve injury resulting from retrieval of more LNs and laterality of surgery, may play a significant role in patient perception of lymphedema after SLNB.

Nomogram for predicting the risk of local recurrence after breast-conserving surgery for ductal carcinoma in situ.

PURPOSE: While the mortality associated with ductal carcinoma in situ (DCIS) is minimal, the risk of ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) is relatively high. Radiation therapy (RT) and antiestrogen agents reduce the risk of IBTR and are considered standard treatment options after BCS. However, they have never been proven to improve survival, and in themselves carry rare but serious risks. Individualized estimation of IBTR risk would assist in decision making regarding the various treatment options for women with DCIS. PATIENTS AND METHODS: From 1991 to 2006, 1,868 consecutive patients treated with BCS for DCIS were identified. A multivariate Cox proportional hazards model was constructed using the 1,681 in whom data were complete. Ten clinical, pathologic, and treatment variables were built into a nomogram estimating probability of IBTR at 5 and 10 years after BCS. The model was validated for discrimination and calibration using bootstrap resampling. RESULTS: The DCIS nomogram for prediction of 5- and 10-year IBTR probabilities demonstrated good calibration and discrimination, with a concordance index of 0.704 (bootstrap corrected, 0.688) and a concordance probability estimate of 0.686. Factors with the greatest influence on risk of IBTR in the model included adjuvant RT or endocrine therapy, age, margin status, number of excisions, and treatment time period. CONCLUSION: The DCIS nomogram integrates 10 clinicopathologic variables to provide an individualized risk estimate of IBTR in a woman with DCIS treated with BCS. This tool may assist in individual decision making regarding various treatment options and help avoid over- and undertreatment of noninvasive breast cancer.

Morbidity of sentinel node biopsy in breast cancer: the relationship between the number of excised lymph nodes and lymphedema.

BACKGROUND: Despite the reduced morbidity associated with sentinel lymph node biopsy (SLNB), lymphedema remains a clinically relevant complication. We hypothesized that a higher number of lymph nodes (LNs) removed during SLNB is associated with a higher risk of lymphedema. METHODS: Six hundred patients with clinically node-negative breast cancer who underwent SLNB were prospectively studied. Circumferential bilateral upper extremity measurements were performed preoperatively and at 3-8 years after surgery. Association of lymphedema with total number of LNs excised and other clinicopathologic variables was analyzed by the Spearman rank correlation coefficient, Fisher's exact test, Wilcoxon rank sum test, and logistic regression. RESULTS: At a median follow-up of 5 years, 5% of patients had developed lymphedema. Factors associated with lymphedema included weight and body mass index. There was no association between the number of LNs removed and the change in upper extremity measurements or in the incidence of lymphedema. Among patients with lymphedema (n = 31) compared to those without, the mean (3.9 vs. 4.2), median (4 vs. 3), and range (1-9 vs. 1-17) of number of LNs removed were similar (P = 0.93). Among the 33 women with ≥ 10 LNs removed, none developed lymphedema. CONCLUSIONS: In this population of 600 women who underwent SLNB, there is no correlation between number of LNs removed and change in upper extremity circumference or incidence of lymphedema. These data suggest that other factors, such as the global disruption of the lymphatic channels during axillary lymph node dissection, play a larger role in development of lymphedema than does the number of LNs removed.

Minimal disease in the sentinel lymph node: how to best measure sentinel node micrometastases to predict risk of additional non-sentinel lymph node disease.

BACKGROUND: Volume of disease in the sentinel lymph node (SLN) is a significant predictor of additional nodal metastasis. This study assesses incidence of residual non-SLN disease in a large cohort of women with minimal SLN metastases and compares three methods of SLN micrometastasis volume measurement to determine which best predicts residual disease on completion axillary lymph node dissection (cALND). METHODS: A total of 505 patients with invasive breast cancer and minimal SLN metastasis (pN1mi or pN0(i+)) underwent cALND and had complete data. All SLNs were evaluated by three measurement methods for volume of metastasis: (1) method of detection (frozen section, routine hematoxylin and eosin, serial hematoxylin and eosin, immunohistochemistry), (2) American Joint Committee on Cancer's AJCC Cancer Staging Manual, 7th edition, N category, and (3) number of metastatic cells (1-100, 101-999, ≥1000). Multivariable logistic regression models were used to predict the presence of additional non-SLN disease. RESULTS: A total of 251 patients (50%) had pN0(i+) and 254 patients (50%) had pN1mi disease. Twelve percent of those with pN0(i+) and 20% with pN1mi had additional non-SLN disease. On multivariate analyses including eight variables, only lymphovascular invasion (odds ratio >2.2, P < 0.01) and volume of nodal metastasis as assessed by any method of measurement (method of detection, AJCC, and cell count) were significantly correlated with additional non-SLN disease (P = 0.04, 0.03, and 0.02, respectively). All three models had similar goodness of fit and discrimination (Akaike information criterion = 442, 442, 441; -2log likelihood = 416, 420, 417; concordance index = 0.680, 0.675, 0.676, respectively). CONCLUSIONS: A significant proportion of women with minimal SLN metastases have additional non-SLN disease at cALND. Assessments of SLN volume of disease by three different methods of measurement are equivalent for prediction of additional non-SLN metastases.

The influence of margin width and volume of disease near margin on benefit of radiation therapy for women with DCIS treated with breast-conserving therapy.

OBJECTIVE AND SUMMARY BACKGROUND DATA: There remains variation in the use of radiation therapy (RT) in women with ductal carcinoma in situ (DCIS), despite prospective randomized trials documenting its benefit in reducing the risk of ipsilateral breast tumor recurrence (IBTR). METHODS: Patients with DCIS treated with excision alone or excision plus RT from 1991 to 1995 were identified. Margin width, number of involved ducts at closest margin, age, presence of palpable mass, presence of lobular neoplasia, nuclear grade, and necrosis were tested in uni- and multivariate analysis for association with risk of IBTR and added value of RT. RESULTS: Two hundred ninety-four patients with a median follow-up of 11 years had actuarial 10- and 15-year overall IBTR rates of 22% and 29%, respectively. For lesions excised with margins of <1 mm, 1 to 9 mm, and >or=10 mm, the actuarial 10-year IBTR rates were 28%, 21%, and 19%, respectively. RT reduced adjusted IBTR rates by 62% (P = 0.002) for all patients; 83% for lesions with <1 mm margins (P = 0.002), 70% for 1 to 9 mm (P = 0.05), and 24% (P = 0.55) for >or=10 mm. After adjustment for other variables, higher volume of disease near the margin was associated with risk of IBTR in the no RT group (HR = 3.37, P = 0.002) and greater benefit of RT (HR 0.14; P = 0.004). CONCLUSION: Effect of RT on IBTR risk is influenced by both margin width and number of involved ducts at nearest margin. Patients with higher volume of disease near the margin derive a greater benefit from the addition of RT. Despite margins of >or=10 mm, the risk of IBTR remains substantial in patients with DCIS.

Concurrent lobular neoplasia increases the risk of ipsilateral breast cancer recurrence in patients with ductal carcinoma in situ treated with breast-conserving therapy.

BACKGROUND: Multiple clinicopathologic factors have been analyzed for their association with an increased risk of ipsilateral breast tumor recurrence (IBTR) after women receive breast-conserving treatment (BCT) for ductal carcinoma in situ (DCIS). The reported incidence of proliferative lesions, such as atypical ductal hyperplasia (ADH), columnar cell changes (CCC), and lobular neoplasia associated with breast cancer, has been as high as 23%; however, the relevance of these lesions on the natural history of DCIS and the risk of IBTR remains unknown. METHODS: Two hundred ninety-four patients with DCIS who received BCT between 1991 and 1995 were identified from the authors' institutional database. Slides were reviewed by a dedicated breast pathologist with particular attention to the presence of lobular neoplasia, ADH, and CCC. The actuarial 5-, 10-, and 15-year IBTR rates were calculated using the Kaplan-Meier method and were compared using the log-rank test. RESULTS: Concurrent lobular neoplasia was present in 41 of 294 patients (14%), ADH was present in 37 of 294 patients (13%), and CCC was present in 71 of 294 patients (24%). The median follow-up was 11 years. IBTR occurred in 40 of 227 patients without lobular neoplasia (18%) versus 15 of 41 patients with lobular neoplasia (37%; P=.005; hazard ratio [HR], 2.49). The 5-, 10-, and 15-year cumulative incidence rates of IBTR were twice as high in women who had DCIS and lobular neoplasia compared with women who had DCIS alone (P=.002). Concomitant ADH (HR, 1.53) and CCC (HR, 1.24) were not associated significantly with IBTR (P=.20 and P=.44, respectively). CONCLUSIONS: Concurrent lobular neoplasia is associated with a significantly higher risk of IBTR in women with DCIS who received BCT. Women with coexisting DCIS and lobular neoplasia who receive BCT should consider using additional risk-reducing strategies.

Outcomes for women with ductal carcinoma-in-situ and a positive sentinel node: a multi-institutional audit.

BACKGROUND: A positive sentinel lymph node (SLN) has been reported in 6% to 13% of patients with ductal carcinoma in situ (DCIS). Although it is well established that nodal status for invasive disease is prognostically important, the clinical relevance of a positive SLN in patients with DCIS remains undetermined. METHODS: SLN biopsy was performed on 470 high-risk patients with DCIS (22% of all patients with DCIS) at 3 institutions. Of these, 43 (9%) had SLN metastases. Pathology findings of positive cases were reviewed, and follow-up was obtained. At 2 of the 3 institutions, data were also collected on DCIS patients who had negative findings on SLN biopsy. For these 414 patients, univariate analyses of tumor characteristics were performed to identify factors associated with node positivity. RESULTS: Extensive disease requiring mastectomy (p = 0.02) and the presence of necrosis (p = 0.04) were associated with an increased risk of nodal positivity. Three (7%) of the 43 SLN-positive patients had macrometastases (pN1), 4 (9%) had micrometastases (pN1mi), and 36 (84%) had single tumor cells or small clusters (pN0(i+)). Of the 25 women that underwent completion axillary dissection, one was found to have a macrometastasis. On pathological review of the primary lesion, 2 (5%) of 43 patints were found to have microinvasion, and 2 (5%) lymphovascular invasion. Nine of 43 (21%) high-risk DCIS patients with a positive SLN and 9/470 (2%) of all high-risk DCIS patients were upstaged to AJCC stage I or II as a result of the SLN biopsy. At a median (range) follow-up of 27 (3-88) months, 1 patient had developed hepatic metastases. This patient had immunohistochemistry detected isolated tumor cells in her SLN (N0(i+)), and upon pathologic review, was found to have high-grade DCIS with microinvasion. CONCLUSION: SLN biopsy for high-risk DCIS patients is a mean of detecting those who may have unrecognized invasive disease and therefore are at risk for distant disease.

Clinicopathologic features and long-term outcomes of 293 phyllodes tumors of the breast.

BACKGROUND: Phyllodes tumors (PT) are rare fibroepithelial neoplasms of the breast with unpredictable behavior. We reviewed our single institution experience with PT over 51 years to identify factors predictive of local recurrence (LR) and metastasis. METHODS: From 1954 to 2005, a total of 352 cases of PT were identified; 293 had follow-up. All available pathology slides (90%) were rereviewed for margins, borders, fibroproliferation in the surrounding breast tissue, stromal pattern, stromal cellularity, frequency of mitoses, and necrosis. RESULTS: All cases occurred in women, with a median age of 42, with 203 originally categorized as benign and 90 as malignant. Median follow-up was 7.9 years. A total of 35 patients developed LR at a median of 2 years. In univariate analyses, a higher actuarial LR rate was associated with positive margins (P = .04), fibroproliferation (P = .001), and necrosis (P = .006). PT classified as malignant did not have a higher risk of LR (P = .79). Five patients developed distant disease at a median of 1.2 years. These patients constituted 71% of the seven patients who had uniformly aggressive pathologic features, including large tumor size (>or=7.0 cm), infiltrative borders, marked stromal overgrowth, marked stromal cellularity, high mitotic count, and necrosis. CONCLUSIONS: Positive margins, fibroproliferation in the surrounding breast tissue, and necrosis are associated with a marked increase in LR rates. Efforts should be made to achieve negative surgical margins to reduce risk of LR. Death from PT is rare (2%), and only PT that demonstrate uniformly aggressive pathologic features seem to be associated with mortality.

Breast cancer susceptibility testing: past, present and future.

Breast cancer is a genetic disease. The cancer phenotype is defined by a complex interplay between oncogenes, tumor-suppressor genes and epigenetic factors. Only 5-10% of all breast cancers can be attributed to one of several breast cancer familial syndromes, the most common of which is the hereditary breast and ovarian syndrome caused by deleterious mutations of the BRCA1 or BRCA2 tumor-suppressor genes. The functions of the BRCA proteins are not fully understood, although it is clear that they play a role in the control of transcription, regulation of the cell cycle and management of DNA damage. The inheritance of a deleterious BRCA mutation is accompanied by a 50-80% risk of developing breast cancer, 60% risk of developing a contralateral breast cancer and 15-25% risk of developing ovarian cancer. The clinical management of BRCA heterozygotes involves several strategies of primary, secondary and tertiary prevention. These include risk-reducing surgery, chemoprevention, lifestyle changes and increased surveillance. As we move beyond the 10-year anniversary of the discovery of the BRCA genes, we are inevitably led to thoughtful reflection on the impact of these genes in regards to the greater problem of sporadic breast cancer.
