Qualitative Assessment of Perceived Organizational Support for Employed Breast Cancer Survivors.

OBJECTIVE: A more detailed understanding of unmet organizational support needs and workplace-based best practices for supporting cancer survivors is needed. METHODS: Ninety-four working breast cancer survivors responded to an open-ended survey question regarding the desired types of organizational support that were and were not received during early survivorship. We performed content-analysis of qualitative data. RESULTS: Major themes included instrumental support, emotional support, and time-based support. The need for flexible arrangements and reduced workloads was mostly met. Unmet needs included navigation/coordination, understanding/empathy, and time off for treatment and recovery. CONCLUSIONS: Organizational support can help cancer survivors manage their health and work roles, diminishing work-health conflict and turnover intent. Study findings can be used to design targeted interventions to fulfill cancer survivors' unmet organizational support needs, which may also apply to workers with other chronic health conditions.

Perceptions of clinical support for employed breast cancer survivors managing work and health challenges.

PURPOSE: A substantial portion of breast cancer survivors are active in the workforce, yet factors that allow survivors to balance work with cancer management and to return to work are poorly understood. We examined breast cancer survivors' most valued/desired types of support in early survivorship. METHODS: Seventy-six employed breast cancer survivors answered an open-ended survey question assessing the most valued/desired support to receive from healthcare providers during early survivorship to manage work and health. Cutrona's (Journal of Social and Clinical Psychology 9:3-14, 1990) optimal matching theory and House's (1981) conceptualization of social support types informed our analyses. Data were content-analyzed to identify themes related to support, whether needed support was received or not, and the types of healthcare providers who provided support. RESULTS: We identified six themes related to types of support. Informational support was valued and mostly received by survivors, but they expected more guidance related to work. Emotional support was valued but lacking, attributed mainly to providers' lack of personal connection and mental health support. Instrumental (practical) support was valued but received by a small number of participants. Quality of life support to promote well-being and functionality was valued and often received. Other themes included non-specific support and non-support. CONCLUSIONS: This study expands our understanding of how breast cancer survivors perceive work-related support from healthcare professionals. Findings will inform targeted interventions designed to improve the support provided by healthcare professionals. IMPLICATIONS FOR CANCER SURVIVORS: Breast cancer survivors managing work and health challenges may benefit by having their unmet support needs fulfilled.

A Predictor of Pathological Complete Response to Neoadjuvant Chemotherapy Stratifies Triple Negative Breast Cancer Patients with High Risk of Recurrence.

We developed a test to predict which patients will achieve pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) and which will have residual disease (RD). Gene expression data from pretreatment biopsies of patients with all breast cancer subtypes were combined into a 519-patient cohort containing 177 TNBC patients. Two RNA classifiers of 16 genes each were sequentially applied to the total cohort, classifying patients into 3 distinct classes. The test performance was further validated in an independent 304-patient cohort. The test accurately identified 70.5% (79/112) of pCR and 83.5% (340/407) of RD patients in the total population, and 75.0% (45/60) of pCR and 75.2% (88/117) of RD patients in the TNBC subset. For the independent cohort, the test identified 91.5% RD patients in the total population and 86.2% RD patients in the TNBC subset. However, the identification of pCR in both total and TNBC population are as low as 21.1% and 30%, respectively. The TNBC RD patients were subdivided by our classifiers, with one class showing significantly higher levels of Ki67 expression and having significantly poorer survival rates than the other classes. This stratification of patients may allow predicted residual disease classes to be assigned an alternative therapy.

Late recurrence of gastric cancer with isolated brain metastasis.

A 70-year-old woman presented to our clinic in 2007 after an evaluation for dysphagia revealed a poorly differentiated adenocarcinoma of the gastroesophogeal junction. Workup for metastatic disease was negative at presentation. She had a complete response to treatment, which was completed in November 2007. She continued to follow up regularly until 2011 when she presented again with neurologic symptoms and was found to have an isolated brain metastasis. She underwent resection of the lesion, and pathology was consistent with her originally diagnosed gastric cancer. The patient received adjuvant radiation therapy, however, unfortunately had rapid progression of disease 1 month later and was transitioned to hospice. Here, we report a rare case of late recurrence of gastric cancer with isolated brain metastasis with a review of literature.

The perfect storm: hemophagocytic lymphohistiocytosis complicating disseminated yersiniosis.

Hemophagocytic lymphohistio-cytosis (HLH) is a rare but serious medical condition with variable clinical outcome. HLH presents real diagnostic and therapeutic challenges to the treating physician despite the major advances in molecular laboratory testing and the immune-chemotherapeutic interventions. Here we present a unique case ofHLH in the setting of hemoglobin H disease provoked by disseminated Yersinia enterocolitica infection. The hemoglobinopathy led to an iron overload state, which provided an optimal milieu for the siderophilic bacterium, Y. enterocolitica, to disseminate. This over whelming infection triggered an uncontrolled and dysregulated inflammatory cytokine cascade with resulting clinical sequelae. The patient was treated conservatively without immunosuppressive therapy and recovered quickly. The long-term outcome of such cases needs further definition.

Breast cancer: assessing response to neoadjuvant chemotherapy by using US-guided near-infrared tomography.

PURPOSE: To assess initial breast tumor hemoglobin (Hb) content before the initiation of neoadjuvant chemotherapy, monitor the Hb changes at the end of each treatment cycle, and correlate these findings with tumor pathologic response. MATERIALS AND METHODS: The HIPAA-compliant study protocol was approved by the institutional review boards of both institutions. Written informed consent was obtained from all patients. Patients who were eligible for neoadjuvant chemotherapy were recruited between December 2007 and May 2011, and their tumor Hb content was assessed by using a near-infrared imager coupled with an ultrasonography (US) system. Thirty-two women (mean age, 48 years; range, 32-82 years) were imaged before treatment, at the end of every treatment cycle, and before definitive surgery. The patients were graded in terms of their final pathologic response on the basis of the Miller-Payne system as nonresponders and partial responders (grades 1-3) and near-complete and complete responders (grades 4 and 5). Tumor vascularity was assessed from total Hb (tHb), oxygenated Hb (oxyHb), and deoxygenated Hb (deoxyHb) concentrations. Tumor vascularity changes during treatment were assessed from percentage tHb normalized to the pretreatment level. A two-sample two-sided t test was used to calculate the P value and to evaluate statistical significance between groups. Bonferroni-Holm correction was applied to obtain the corrected P value for multiple comparisons. RESULTS: There were 20 Miller-Payne grade 1-3 tumors and 14 grade 4 or 5 tumors. Mean maximum pretreatment tHb, oxyHb, and deoxyHb levels were significantly higher in grade 4 and 5 tumors than in grade 1-3 tumors (P = .005, P = .008, and P = .017, respectively). The mean percentage tHb changes were significantly higher in grade 4 or 5 tumors than in grade 1-3 tumors at the end of treatment cycles 1-3 (P = .009 and corrected P = .009, P = .002 and corrected P = .004, and P < .001 and corrected P < .001, respectively). DISCUSSION: These findings indicate that initial tumor Hb content is a strong predictor of final pathologic response. Additionally, the tHb changes during early treatment cycles can further predict final pathologic response.

Prevalence and prognostic role of triple-negative breast cancer by race: a surveillance study.

INTRODUCTION: Emerging research suggests a substantially greater prevalence of the adverse triple-negative (TN) subtype (human epidermal growth factor receptor [HER]2(-), estrogen receptor [ER](-), and progesterone receptor [PR])(-)) among black patients with breast cancer. No reports however have been generated from a statewide cancer registry. PATIENTS AND METHODS: The study consisted of all black patients (N = 643) and a random sample of white patients (n = 719) diagnosed with primary invasive breast cancer (2000-2003) listed in the National Cancer Institute-Surveillance Epidemiology and End Results (NCI-SEER) Connecticut Tumor Registry (CTR). HER2 status was obtained from pathology reports submitted to the registry. Remaining data were obtained from the registry database. RESULTS: TN tumors were more prevalent in black compared with white patients (30.8% vs. 11.2%, respectively; P < .001.) There was a 2-fold greater frequency of ER(-) and PR(-) phenotypes among black patients, but HER2 status did not differ by race. Patients with lobular cancer were less likely to have TN breast cancer compared with patients with ductal tumors (odds ratio [OR] = 0.23; 95% confidence interval [CI], 0.10-0.58). Among patients with regional disease, black patients exhibited increased risk of death (relative risk [RR] = 2.71; 95% CI, 1.48-4.97) independent of TN status. No survival disparity was found among patients with local disease. DISCUSSION: These registry-based data corroborate reports that TN breast cancer varies substantially by race and histologic subtype. A survival disparity among patients with advanced disease, but not local disease, casts some doubt on TN status as an explanation for differences. CONCLUSION: More research is warranted to understand why black patients with advanced breast cancer may be at increased risk for death whether or not their tumors express the TN phenotype.

Early-stage invasive breast cancers: potential role of optical tomography with US localization in assisting diagnosis.

PURPOSE: To investigate the potential role of optical tomography in the near-infrared (NIR) spectrum with ultrasonographic (US) localization as a means of differentiating early-stage cancers from benign lesions of the breast. MATERIALS AND METHODS: The protocol was approved by the institutional review boards and was HIPAA compliant; all participants signed an informed consent. One hundred seventy-eight consecutive women (mean age, 52 years; range, 21-89 years) who underwent US-guided biopsy were imaged with a hand-held probe consisting of a coregistered US transducer and an NIR imager. The lesion location provided by coregistered US was used to guide optical imaging. Light absorption was measured at two optical wavelengths. From this measurement, tumor angiogenesis was assessed on the basis of calculated total hemoglobin concentration (tHb) and was correlated with core biopsy results. For patients diagnosed with carcinomas and followed up with subsequent excision, the tHb was correlated with pathologic parameters. RESULTS: There were two in situ carcinomas (Tis), 35 T1 carcinomas, 24 T2-T4 carcinomas, and 114 benign lesions. The mean maximum and mean average tHb of the Tis-T1 group were 102.0 micromol/L +/- 28.5 (standard deviation) and 71.9 micromol/L +/- 18.8, and those of the T2-T4 group were 100.3 micromol/L +/- 26.4 and 67.0 micromol/L +/- 18.3, respectively. The mean maximum and mean average tHb of the benign group were 55.1 micromol/L +/- 22.7 and 39.1 micromol/L +/- 14.9, respectively. Both mean maximum and mean average tHb levels were significantly higher in the malignant groups than they were in the benign group (P < .001). The sensitivity, specificity, positive predictive value, and negative predictive value for Tis-T1 cancers were 92%, 93%, 81%, and 97%. The corresponding values for T2-T4 tumors were 75%, 93%, 69%, and 95%. CONCLUSION: The angiogenesis (tHb) contrast imaged by using the NIR technique with US holds promise as an adjunct to mammography and US for distinguishing early-stage invasive breast cancers from benign lesions.

Combination of imatinib mesylate with autologous leukocyte-derived heat shock protein and chronic myelogenous leukemia.

PURPOSE: To test the feasibility, safety, immunogenicity, and clinical efficacy of an autologous vaccine of leukocyte-derived heat shock protein 70-peptide complexes (Hsp70PC), in conjunction with imatinib mesylate, in patients with chronic myeloid leukemia (CML) in chronic phase. EXPERIMENTAL DESIGN: Patients had cytogenetic or molecular evidence of disease, despite treatment with imatinib mesylate for all except one patient, at the beginning of study. Hsp70PCs were purified from the leukopheresed peripheral blood mononuclear cells and were administered in eight weekly intradermal injections at 50 microg/dose without adjuvant. Clinical responses were assessed by bone marrow analysis before and after vaccinations. An IFN-gamma enzyme-linked immunospot assay was used to estimate the effect of treatment on natural killer cells and T cells against CML. RESULTS: Twenty patients were treated. The manufacturing of Hsp70PCs was successful and the administration was safe for all patients. Minimal or no side effects were reported. Clinical responses were seen in 13 of 20 patients as measured by cytogenetic analysis of bone marrow Philadelphia chromosome-positive cells in metaphases and/or, when possible, the level of Bcr/Abl transcript by PCR. Immunologic responses were observed in 9 of 16 patients analyzed, characterized by an increase in the frequency of CML-specific IFN-gamma-producing cells and IFN-gamma-secreting natural killer cells in the blood. A significant correlation between clinical responses and immunologic responses was observed. CONCLUSIONS: Autologous Hsp70PC vaccination is feasible and safe. When combined with imatinib mesylate, it is associated with immunologic and possible clinical responses against CML in chronic phase.
