RESUMO
Clinical implementation of evidence-based practice (EBP) tools is a healthcare priority. The Dynamic Grade of Swallowing Toxicity (DIGEST) is an EBP tool developed in 2016 for videofluoroscopy in head and neck (H&N) oncology with clinical implementation as a goal. We sought to examine: (1) feasibility of clinical implementation of DIGEST in a national comprehensive cancer center, and (2) fidelity of DIGEST adoption in real-world practice. A retrospective implementation evaluation was conducted in accordance with the STARI framework. Electronic health record (EHR) databases were queried for all consecutive modified barium swallow (MBS) studies conducted at MD Anderson Cancer Center from 2016 to 2021. Implementation outcomes included: feasibility as measured by DIGEST reporting in EHR (as a marker of clinical use) and fidelity as measured by accuracy of DIGEST reporting relative to the decision-tree logic (penetration-aspiration scale [PAS], residue, and Safety [S] and Efficiency [E] grades). Contextual factors examined included year, setting, cancer type, MBS indication, and provider. 13,055 MBS were conducted by 29 providers in 7,842 unique patients across the lifespan in diverse oncology populations (69% M; age 1-96 years; 58% H&N cancer; 10% inpatient, 90% outpatient). DIGEST was reported in 12,137/13,088 exams over the 6-year implementation period representing 93% (95% CI: 93-94%) adoption in all exams and 99% (95% CI: 98-99%) of exams excluding the total laryngectomy population (n = 730). DIGEST reporting varied modestly by year, cancer type, and setting/provider (> 91% in all subgroups, p < 0.001). Accuracy of DIGEST reporting was high for overall DIGEST (incorrect SE profile 1.6%, 200/12,137), DIGEST-safety (incorrect PAS 0.4% 51/12,137) and DIGEST-efficiency (incorrect residue 1.2%, 148/12,137). Clinical implementation of DIGEST was feasible with high fidelity in a busy oncology practice across a large number of providers. Adoption of the tool across the lifespan in diverse cancer diagnoses may motivate validation beyond H&N oncology.
RESUMO
BACKGROUND: Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) is a validated method to grade the severity of pharyngeal swallowing impairment as a toxicity of cancer based on the degree and patterns of penetration/aspiration and pharyngeal residue over a standardly acquired radiographic modified barium swallow (MBS) study. Since its implementation in 2016, areas for the refinement of grading mild safety impairments have been identified by clinical and research users. The objective of this study was to assess the performance and validity of refined DIGESTsafety grading criteria (per DIGEST version 2 [DIGESTv2 ]). METHODS: Refined safety criteria were developed and vetted with clinical and research users. DIGESTv2 included 2 changes to the safety criteria. All MBSs with blinded DIGEST version 1 grading were sampled from a registry database (1331 patients underwent MBS over the period of December 2005 to July 2019). New criteria were applied to derive DIGESTsafety grading version 2. Measures of criterion validity, including the MD Anderson Dysphagia Inventory [MDADI] composite score, the Modified Barium Swallow Impairment Profile (MBSImP) pharyngeal total, the MBSImP hyolaryngeal components (items 8-11), and the Performance Status Scale for Head and Neck Cancer Patients [PSS-HN] diet, were correlated with DIGESTsafety and overall DIGEST grades from versions 1 and 2 and were compared pairwise between reassigned grades. RESULTS: With the application of version 2 safety criteria, 112 of 1331 examinations (8.4%) and 79 of 1331 examinations (5.9%) changed in their DIGESTsafety and overall grades, respectively. The safety and overall DIGEST grades (versions 1 and 2) significantly correlated with criterion measures, including the MBSImP pharyngeal total, laryngeal MBSImP parameters of interest, MDADI, and PSS-HN (P < .0001); correlations maintained a similar magnitude between versions 1 and 2. Forty-six upgraded examinations (reassigned from safety grade 1 per version 1 to grade 2 per version 2) performed similarly to other safety grade 2 examinations (version 1), and this was likewise true for 66 downgraded examinations (reassigned from safety grade 1 per version 1 to grade 0 per version 2). CONCLUSIONS: Refined criteria defining mild safety impairments with the DIGEST methodology changed grades in small numbers of examinations. DIGESTv2 criteria maintained criterion validity, demonstrated ordinality, and improved the performance of the method in these rare scenarios. LAY SUMMARY: Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) is a method developed and validated by the investigators in 2016 to grade the severity of pharyngeal swallowing dysfunction (dysphagia) with a decision tree or flowsheet to guide the clinician's review of a standard radiographic modified barium swallow study. This work reports on the validity of updated DIGEST criteria (version 2) that incorporate 2 modifications to the decision tree.

BACKGROUND: Delirium, poor performance status, and dyspnea predict short survival in the palliative care setting. OBJECTIVE: Our goal was to determine whether these three conditions, which we refer to as a "triple threat," also predict mortality among patients with advanced cancers in the emergency department (ED). METHODS: The study sample included 243 randomly selected, clinically stable patients with advanced cancer who presented to our ED. The analysis included patients who had delirium (Memorial Delirium Assessment Scale score ≥ 7), poor performance status (Eastern Cooperative Oncology Group performance status score of 3 or 4), or dyspnea as a presenting symptom. We obtained survival data from medical records. We calculated predicted probability of dying within 30 days and association with number of symptoms after the ED visit using logistic regression analysis. RESULTS: Twenty-eight patients died within 30 days after presenting to the ED. Death within 30 days occurred in 36% (16 of 44) of patients with delirium, 28% (17 of 61) of patients with poor performance status, and 14% (7 of 50) of patients with dyspnea, with a predicted probability of 30-day mortality of 0.38 (95% confidence interval [CI] 0.25-0.53), 0.28 (95% CI 0.18-0.40), and 0.15 (95% CI 0.07-0.29), respectively. The predicted probability of death within 30 days for patients with two or three of the conditions was 0.49 (95% CI 0.34-0.66) vs. 0.05 (95% CI 0.02-0.09) for patients with none or one of the conditions. CONCLUSIONS: Patients with advanced cancers who present to the ED and have at least two triple threat conditions have a high probability of death within 30 days.

Purpose Acute radiation-induced esophagitis (ARIE) leads to treatment delays, decreased quality of life (QOL), and secondary adverse events such as weight loss. Grade 3 ARIE occurs in 15%-30% of patients undergoing radiotherapy to the esophagus, leading to disruption or discontinuation of treatment. The purpose of this study was to assess the effects of glutamine, a common nutritional supplement, on ARIE in patients with thoracic malignancies. Patients and methods This double-blind, placebo-controlled trial enrolled patients with advanced thoracic malignancies receiving concurrent chemotherapy/radiotherapy or radiotherapy alone, with radiation doses to the esophagus ≥45 Gy. Patients were randomized (1:1) to receive 4 g of glutamine or glycine placebo twice daily. The primary objective was to determine whether glutamine decreases the severity of ARIE in these patients. Secondary objectives included assessment of the effects of glutamine on other measures of ARIE, weight, symptom burden measure assessed by the MD Anderson Symptom Inventory (MDASI-HN) questionnaire and the toxicity profile of glutamine. Results At the time of interim analysis, 53 patients were enrolled: 27 in the glutamine arm and 26 in the placebo arm. There was no difference in the incidence of esophagitis in the first 6 weeks of radiotherapy between the glutamine and placebo arms (74% versus 68%; P = 1.00). There were no significant differences between the two arms for time to onset of esophagitis. The duration of ARIE was shorter (6.3 versus 7.1 weeks; P = 0.54) and median weight loss was lower (0.9 kg versus 2.8 kg; p = 0.83) in the glutamine arm versus the placebo arm. The groups differ significantly in core symptom severity (2.1 vs 1.5, p < .03) but not in head and neck specific symptom severity (1.2 vs 1.1, p < .60) nor in symptom interference (2.1 vs 1.7, p < .22). There was no grade 3 or higher adverse event at least possibly related to glutamine. The study was terminated for futility following interim analysis. Conclusion Oral glutamine was not associated with significant improvement in severity of ARIE, weight loss, head and neck specific symptoms or symptom interference compared with placebo in patients with advanced thoracic malignancies receiving radiotherapy to the esophagus.Clinical trial information. NCT01952847, and date of registration is September 30, 2013.

BACKGROUND: Optimal hepatitis C virus (HCV) screening strategies for cancer patients have not been established. We compared the performance of selective HCV screening strategies. METHODS: We surveyed patients presenting for first systemic anticancer therapy during 2013-2014 for HCV risk factors. We estimated the prevalence of positivity for HCV antibody (anti-HCV) and examined factors associated with anti-HCV status using Fisher's exact test or Student's t test. Sensitivity was calculated for screening patients born during 1945-1965, patients with ≥ 1 other risk factor, or both cohorts ("combined screening"). RESULTS: We enrolled 2122 participants. Median age was 59 years (range, 18-91); 1138 participants were women. Race/ethnicity distribution was white non-Hispanic, 76% (n = 1616); Hispanic, 11% (n = 233); black non-Hispanic, 8% (n = 160); Asian, 4% (n = 78); and other, 2% (n = 35). Primary cancer distribution was non-liver solid tumor, 78% (n = 1664); hematologic cancer, 20% (n = 422); and liver cancer, 1% (n = 28). Prevalence of anti-HCV was 1.93% (95% CI, 1.39%-2.61%). Over 28% of patients with detectable HCV RNA were unaware of infection. Factors significantly associated with anti-HCV positivity included less than a bachelor's degree, birth in 1945-1965, chronic liver disease, injection drug use, and blood transfusion or organ transplant before 1992. A total of 1315 participants (62%), including 39 of 41 with anti-HCV, reported ≥ 1 risk factor. Sensitivity was 80% (95% CI, 65-91%) for birth-cohort-based, 68% (95% CI, 52-82%) for other-risk-factor-based, and 95% (95% 83-99%) for combined screening. CONCLUSION: Combined screening still missed 5% of patients with anti-HCV. These findings favor universal HCV screening to identify all HCV-infected cancer patients.

BACKGROUND: Patients with metastatic breast cancer with bone-only metastases (BOM) are a unique patient population without consensus regarding high-risk characteristics, which we sought to establish. METHODS: We identified 1,445 patients with BOM followed for at least 6 months at MD Anderson Cancer Center from January 1, 1997, to December 31, 2015. RESULTS: Seventy-one percent (n = 936) of the 1,325 patients with BOM with available pain characterization were symptomatic at time of BOM diagnosis. Pain was more common in patients with lytic compared with blastic or sclerotic metastases (odds ratio [OR], 1.79; 95% confidence interval [CI,] 1.26-2.53) and multiple versus single bone metastases (OR, 1.37; 95% CI, 1.03-1.83). Poorer overall survival (OS) was also noted in patients with multiple bone metastases (median OS, 4.80 years; 95% CI, 4.49-5.07) compared with single bone metastasis (median OS, 7.54 years; 95% CI, 6.28-10.10) and in patients with metastases in both the axial and appendicular skeleton (median OS, 4.58 years; 95% CI, 4.23-4.96) compared with appendicular-only (median OS, 6.78 years; 95% CI, 5.26-7.96) or axial-only metastases (median OS, 5.62 years; 95% CI, 4.81-6.69). Black/non-Hispanic patients had poorer outcomes, and patients aged 40-49 years at time of breast cancer diagnosis had significantly better OS compared with both younger and older patient groups. CONCLUSION: Overall, several risk features for decreased OS were identified, including multiple bone metastases and both axial and appendicular skeleton involvement. Multiple bone metastases and lytic bone metastases were associated with increased pain. IMPLICATIONS FOR PRACTICE: Patients with metastatic breast cancer and bone-only metastases (BOM) represent a poorly characterized patient subset. The ability to identify unique patient characteristics at time of BOM diagnosis associated with increased morbidity or mortality would allow for recognition of patients who would benefit from more aggressive therapy. In this study, the largest sample of patients with BOM thus far reported is characterized, highlighting several higher-risk BOM groups, including those with multiple bone metastases and bone metastases in both the axial and appendicular skeleton at time of BOM diagnosis. In addition to tailoring current practices for these high-risk patients, ongoing studies of these patients are indicated.

BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is an aggressive, often fatal soft tissue sarcoma that lacks an optimal salvage regimen. We retrospectively reviewed data from 29 pretreated DSRCT patients who received pazopanib at MD Anderson Cancer Center after failure of standard chemotherapies. SUBJECTS, MATERIALS, AND METHODS: Medical records of patients treated from January 2012 to December 2016 were reviewed and regression analyses were performed. Median progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method and differences in survival were assessed by a log-rank test. A landmark statistical analysis was used to assess OS at a predefined 12-week time point following pazopanib initiation. RESULTS: The mean age at pazopanib treatment was 27.5 years (range, 6.3-50.1 years). According to RECIST 1.1 criteria, 16 patients (55%) had stable disease, 1 patient (3%) had partial response, 1 patient (3%) had complete response, and 11 patients (38%) had progressive disease. Estimated median PFS was 5.63 months (95% confidence interval [CI]: 3.23-7.47). Median OS was 15.7 months (95% CI: 10.3-32.4). As of December 2016, 11 patients (38%) were still alive, with a median follow-up time of 16.8 (range 3.8-30.1) months. Doses between 400 and 800 mg were included. Pazopanib was well tolerated and 23 (79%) of the patients continued it until progression or death, 4 discontinued because of side effects, and 2 were still on pazopanib at the time of data analysis. CONCLUSION: In the largest study conducted to date in DSRCT, pazopanib was well tolerated and clinically active in heavily pretreated patients who otherwise lack good treatment options. IMPLICATIONS FOR PRACTICE: Desmoplastic small round cell tumor (DSRCT) is a rare, extremely aggressive soft tissue sarcoma subtype that most commonly occurs in adolescent and young adult males. No DSRCT-specific therapies exist, and for lack of a better treatment approach, current therapies have relied upon U.S. Food and Drug Administration-approved drugs like pazopanib that exhibit clinical activity in other sarcoma subtypes. This article describes the largest experience to date using pazopanib as salvage treatment in heavily pretreated DSRCT patients. Pazopanib was well tolerated and clinically active, surpassing predefined metrics proposed by the European Organization for Research and Treatment of Cancer indicative of "active" sarcoma drugs (5.63 months progression-free survival [PSF], with 62% of the study population achieving progression-free survival at 12 weeks).

Clinician-reported toxicity grading through common terminology criteria for adverse events (CTCAE) stages dysphagia based on symptoms, diet, and tube dependence. The new dynamic imaging grade of swallowing toxicity (DIGEST) tool offers a similarly scaled five-point ordinal summary grade of pharyngeal swallowing as determined through results of a modified barium swallow (MBS) study. This study aims to inform clinicians on the similarities and differences between dysphagia severity according to clinical CTCAE and MBS-derived DIGEST grading. A cross-sectional sample of 95 MBS studies was randomly selected from a prospectively-acquired MBS database among patients treated with organ preservation strategies for head and neck cancer. MBS DIGEST and clinical CTCAE dysphagia grades were compared. DIGEST and CTCAE dysphagia grades had "fair" agreement per weighted κ of 0.358 (95% CI .231-.485). Using a threshold of DIGEST ≥ 3 as reference, CTCAE had an overall sensitivity of 0.50, specificity of 0.84, and area under the curve (AUC) of 0.67 to identify severe MBS-detected dysphagia. At less than 6 months, sensitivity was 0.72, specificity was 0.76, and AUC was 0.75 while at greater than 6 months, sensitivity was 0.22, specificity was 0.90, and AUC was 0.56 for CTCAE to detect dysphagia as determined by DIGEST. Classification of pharyngeal dysphagia on MBS using DIGEST augments our understanding of dysphagia severity according to the clinically-derived CTCAE while maintaining the simplicity of an ordinal scale. DIGEST likely complements CTCAE toxicity grading through improved specificity for physiologic dysphagia in the acute phase and improved sensitivity for dysphagia in the late-phase.

BACKGROUND: To improve the management of advanced cancer patients with delirium in an emergency department (ED) setting, we compared outcomes between patients with delirium positively diagnosed by both the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS), or group A (n = 22); by the MDAS only, or group B (n = 22); and by neither CAM nor MDAS, or group C (n = 199). MATERIALS AND METHODS: In an oncologic ED, we assessed 243 randomly selected advanced cancer patients for delirium using the CAM and the MDAS and for presence of advance directives. Outcomes extracted from patients' medical records included hospital and intensive care unit admission rate and overall survival (OS). RESULTS: Hospitalization rates were 82%, 77%, and 49% for groups A, B, and C, respectively (p = .0013). Intensive care unit rates were 18%, 14%, and 2% for groups A, B, and C, respectively (p = .0004). Percentages with advance directives were 52%, 27%, and 43% for groups A, B, and C, respectively (p = .2247). Median OS was 1.23 months (95% confidence interval [CI] 0.46-3.55) for group A, 4.70 months (95% CI 0.89-7.85) for group B, and 10.45 months (95% CI 7.46-14.82) for group C. Overall survival did not differ significantly between groups A and B (p = .6392), but OS in group C exceeded those of the other groups (p < .0001 each). CONCLUSION: Delirium assessed by either CAM or MDAS was associated with worse survival and more hospitalization in patients with advanced cancer in an oncologic ED. Many advanced cancer patients with delirium in ED lack advance directives. Delirium should be assessed regularly and should trigger discussion of goals of care and advance directives. IMPLICATIONS FOR PRACTICE: Delirium is a devastating condition among advanced cancer patients. Early diagnosis in the emergency department (ED) should improve management of this life-threatening condition. However, delirium is frequently missed by ED clinicians, and the outcome of patients with delirium is unknown. This study finds that delirium assessed by the Confusion Assessment Method or the Memorial Delirium Assessment Scale is associated with poor survival and more hospitalization among advanced cancer patients visiting the ED of a major cancer center, many of whom lack advance directives. Therefore, delirium in ED patients with cancer should trigger discussion about advance directives.

BACKGROUND: Inflammatory breast cancer (IBC) is an aggressive form of breast cancer characterized by rapid progression and early metastatic dissemination. The purpose of this study was to assess contemporary rates of local regional recurrence (LRR) in the era of trimodality therapy for nonmetastatic IBC and identify risk factors leading to local failure. METHODS: A total of 114 patients with nonmetastatic IBC receiving trimodality therapy (neoadjuvant chemotherapy, surgery, and radiation therapy) were identified from a prospectively collected database from 2007 to 2015 and outcomes analyzed. RESULTS: Median age at diagnosis was 52 years, and the median follow-up was 3.6 years. Sixty-three (55%) patients presented with N2 IBC, and 52 patients (45%) presented with N3 IBC. Local regional recurrence was observed during follow-up for four patients; 25 died, and 85 were censored at last follow-up. Surgical margins were negative in 99% of patients (n = 113). The 2-year probability of LRR was 3.19% (95% confidence interval 1.03-9.90%). Five-year overall survival for this cohort was 69.14%. Improvement in disease-free survival was seen among patients with HER2+ subtype, clinical stage IIIB, complete or partial radiologic response to neoadjuvant therapy, pathologic complete response, and lower nodal burden on presentation. CONCLUSIONS: Locoregional recurrences were rare at a median of 3.6 years follow-up in a contemporary cohort of IBC patients treated with trimodality therapy. Although longer follow-up is needed, aggressive surgical resection to negative margins in the frame of trimodality therapy with curative intent can lead to LRR rates that mirror non-IBC rates.

BACKGROUND: The frequency of delirium among patients with cancer presenting to the emergency department (ED) is unknown. The purpose of this study was to determine delirium frequency and recognition by ED physicians among patients with advanced cancer presenting to the ED of The University of Texas MD Anderson Cancer Center. METHODS: The study population was a random sample of English-speaking patients with advanced cancer who presented to the ED and met the study criteria. All patients were assessed with the Confusion Assessment Method (CAM) to screen for delirium and with the Memorial Delirium Assessment Scale (MDAS) to measure delirium severity (mild, ≤15; moderate, 16-22; and severe, ≥23). ED physicians were also asked whether their patients were delirious. RESULTS: Twenty-two of the 243 enrolled patients (9%) had CAM-positive delirium, and their median MDAS score was 14 (range, 9-21 [30-point scale]). The median age of the enrolled patients was 62 years (range, 19-89 years). Patients with delirium had a poorer performance status than patients without delirium (P < .001); however, the 2 groups did not differ in other characteristics. Ten of the 99 patients who were 65 years old or older (10%) had CAM-positive delirium, whereas 12 of the 144 patients younger than 65 years (8%) did (P = .6). According to the MDAS scores, delirium was mild in 18 patients (82%) and moderate in 4 patients (18%). Physicians correctly identified delirium in 13 of the CAM-positive delirious patients (59%). CONCLUSIONS: Delirium is relatively frequent and is underdiagnosed by physicians in patients with advanced cancer who are visiting the ED. Further research is needed to identify the optimal screening tool for delirium in ED. Cancer 2016. © 2016 American Cancer Society. Cancer 2016;122:2918-2924. © 2016 American Cancer Society.

INTRODUCTION: The differentiation of benign parathyroid gland atypia and true parathyroid carcinoma (PC) can be challenging. In some instances, patients are classified as having 'atypical parathyroid neoplasms' (APNs), explicitly acknowledging that the distinction between benign and malignant disease appears impossible to determine. This 'grey area' diagnosis makes rendering an accurate prognosis difficult, and clouds clinical management and treatment planning. METHODS: We performed a retrospective chart review of all patients undergoing operation for primary hyperparathyroidism in our institution (2000-2014). Patients with a histopathological diagnosis of PC or APN were included. Demographics, clinical characteristics, and survival rates were analyzed, and analysis was conducted using SAS 9.4 (SAS Institute, Inc., Cary, NC, USA). RESULTS: Fifty-four patients were included in the study-31 (57.41 %) with PC and 23 (42.59 %) with APN. PC versus APN was associated with higher parathyroid hormone (PTH) (p = 0.005) and with males (p = 0.002). Five-year overall survival (OS) from diagnosis was 82.64 % [95 % confidence interval (CI) 59.82-93.17] for the PC group and 93.33 % (95 % CI 61.26-99.03) for the APN group, while the 5-year recurrence-free survival rate was 59.63 % (95 % CI 36.32-76.81) in the PC group and 90.91 % (95 % CI 50.81-98.67) in the APN group. CONCLUSION: PC and APN are distinct clinical entities with differences in tumor biology reflected in overall recurrence rates, disease-free survival, and OS. APNs present with a less accentuated biochemical profile and demonstrate an indolent clinical course compared with PCs. Efforts to improve categorization and staging of PC and APN are needed.

BACKGROUND AND OBJECTIVES: Parathyroid carcinoma (PC) is rare but potentially lethal. No standardized staging system or treatment guidelines have been established. We aimed to determine whether management of PC and patient outcomes have changed at our institution over the past 35 years. METHODS: Retrospective review of patients with PC at our institution between 1980 and 2015. Patients were grouped by date of initial surgery: group 1, 1980-2001; group 2, 2002-2015. RESULTS: About 57 patients (26 in group 1; 31 in group 2) were included. Group 2 had more female patients (61%) than group 1 (31%; P = 0.033). Patients in group 2 were older at the time of initial operation (mean age 48 years in group 1 (SD:14.3) and 56 years (SD:14.6) in group 2; P = 0.034). The 5-year OS rates were 82% (95%CI 59.6%, 93%) for group 1 and 72% (95%CI 45.0%, 87.7%) for group 2. The 5-year DFS rates were 62% (95%CI 36.4%, 79.9%) for group 1 and 66% (95%CI 40.6%, 82.2%) for group 2. CONCLUSION: Management of PC and patient outcomes (OS and DFS) have not significantly changed over the past 35 years at our institution. This rare malignancy needs oncologic improvement. J. Surg.

BACKGROUND: Angiogenesis plays a role in tumor growth and is partly mediated by factors in both the fibroblast growth factor (FGF) and vascular endothelial growth factor (VEGF) pathways. Durable clinical responses with VEGF tyrosine kinase inhibitors (TKIs) may be limited by intrinsic tumor resistance. We hypothesized that FGF signaling may impact clinical responses to sorafenib. METHODS: Nephrectomy material was available from 40 patients with metastatic renal cell carcinoma (RCC) enrolled in a phase II clinical trial of sorafenib ± interferon (ClinicalTrials.gov Identifier NCT00126594). Fibroblast growth factor receptor 1 (FGFR1) and fibroblast growth factor receptor substrate 2 alpha (FRS2α) expression was assessed by in situ hybridization and immunofluorescence, respectively. The relationship between fibroblast growth factor pathway marker levels and progression-free survival (PFS) was analyzed using Kaplan-Meier and Cox proportional hazards regression methods. RESULTS: Univariate analysis indicated that more intense FGFR1 staining was associated with shorter PFS (log-rank P = 0.0452), but FRS2α staining was not significantly associated with PFS (log-rank P = 0.2610). Multivariate Cox proportional hazards regression models were constructed for FGFR1 and FRS2α individually, adjusting for baseline Eastern Cooperative Oncology Group performance status, treatment arm and anemia status. When adjusted for each of these variables, the highest intensity level of FGFR1 (level 3 or 4) had increased progression risk relative to the lowest intensity level of FGFR1 (level 1) (P = 0.0115). The highest intensity level of FRS2α (level 3 or 4) had increased progression risk relative to the lowest intensity level of FRS2α (level 1) (P = 0.0126). CONCLUSIONS: Increased expression of FGFR1 and FRS2α was associated with decreased PFS among patients with metastatic RCC treated with sorafenib. The results suggest that FGF pathway activation may impact intrinsic resistance to VEGF receptor inhibition.

PURPOSE: Merkel cell carcinoma is a rare but potentially deadly cancer of the eyelid. To date, no studies have reported on clinical parameters at initial presentation of the eyelid tumor that may correlate with disease-free survival (DFS). The purpose of this study was to determine whether the American Joint Committee on Cancer (AJCC) T category for eyelid carcinoma correlates with metastasis and DFS in patients with Merkel cell carcinoma of the periocular region. METHODS: This is a retrospective cohort study from a tertiary referral cancer center. All consecutive patients treated for eyelid or periocular Merkel cell carcinoma between November 1, 1998, and November 1, 2012, were reviewed. The main outcome measures included AJCC T category for eyelid carcinoma and Merkel cell carcinoma at presentation, nodal metastasis at presentation, metastasis during follow up, and DFS. RESULTS: The study included 18 patients, 7 men and 11 women, with median age of 68.5 years. The AJCC T categories for both eyelid carcinoma and Merkel cell carcinoma were significantly correlated with DFS. Using the T categories for eyelid carcinoma, when TX and T2a were grouped into a single category and T2b and T3a into another category, the estimated DFS rate at 3 years was 100% for patients with TX or T2a lesions and 57% for patients with T2b or T3a lesions (p=0.0298). Four patients (22%) had lymph node metastasis at presentation. Presence of lymph node metastasis at presentation was the strongest single predictor of shorter DFS and an increased risk of metastasis during follow up (p=0.0222). CONCLUSIONS: The AJCC eyelid carcinoma T at presentation correlates with DFS in patients with Merkel cell carcinoma of the periocular region. The DFS rate at 3 years was significantly worse for patients with T2b or more extensive tumors by eyelid carcinoma T category. Presence of lymph node metastasis at presentation was predictive of shorter DFS and an increased risk of metastasis during follow up.

BACKGROUND: The purpose of this analysis was to compare disease-free survival (DFS), progression-free survival (PFS), and overall survival (OS) between pregnant and nonpregnant patients with breast cancer. METHODS: From 1989 to 2009, 75 women were treated with chemotherapy during pregnancy. Each pregnant case was matched on age and cancer stage to two nonpregnant patients with breast cancer (controls). Fisher's exact test, the Kaplan-Meier method, and Cox proportional hazards regression models were used. RESULTS: Median follow-up time for patients who were alive at the end of follow-up (n = 159) was 4.20 years (range: 0.28-19.94 years). DFS at 5 years was 72% (95% confidence interval [CI]: 58.3%-82.1%) for pregnant patients and 57% (95% CI: 46.7%-65.8%) for controls (p = .0115). Five-year PFS was 70% (95% CI: 56.8%-80.3%) for pregnant patients and 59% (95% CI: 49.1%-67.5%) for controls (p = .0252). Five-year OS was 77% (95% CI: 63.9%-86.4%) for pregnant patients and 71% (95% CI: 61.1%-78.3%) for controls (p = .0461). Hazard ratio estimates favored improved survival for pregnant patients in univariate analyses and multivariate analyses, controlling for age, year of diagnosis, stage, and tumor grade. CONCLUSIONS: For patients who received chemotherapy during pregnancy, survival was comparable to-if not better than-that of nonpregnant women. Pregnant patients with breast cancer should receive appropriate local and systemic therapy for breast cancer.

BACKGROUND: American Thyroid Association (ATA) guidelines suggest that thyroidectomy can be delayed in some children with multiple endocrine neoplasia syndrome 2A (MEN2A) if serum calcitonin (Ct) and neck ultrasonography (US) are normal. We hypothesized that normal US would not exclude a final pathology diagnosis of medullary thyroid cancer (MTC). METHODS: We retrospectively queried a MEN2A database for patients aged<18 years, diagnosed through genetic screening, who underwent preoperative US and thyroidectomy at our institution, comparing preoperative US and Ct results with pathologic findings. RESULTS: 35 eligible patients underwent surgery at median age of 6.3 (range 3.0-13.8) years. Mean MTC size was 2.9 (range 0.5-6.0) mm. The sensitivity of a US lesion≥5 mm in predicting MTC was 13% [95% confidence interval (CI) 2%, 40%], and the specificity was 95% [95% CI 75%, 100%]. Elevated Ct predicted MTC in 13/15 patients (sensitivity 87% [95% CI 60%, 98%], specificity 35% [95% CI 15%, 59%]). The area under the receiver operating characteristic curve (AUC) for using US lesion of any size to predict MTC was 0.50 [95% CI 0.33, 0.66], suggesting that US size has poor ability to discriminate MTC from non-MTC cases. The AUC for Ct level at 0.65 [95% CI 0.46, 0.85] was better than that of US but not age [AUC 0.62, 95% CI 0.42, 0.82]. CONCLUSIONS: In asymptomatic children with MEN2A diagnosed by genetic screening, preoperative thyroid US was not sensitive in identifying MTC of any size and, when determining the age for surgery, should not be used to predict microscopic MTC.

Melanoma, due to its metastatic rate, is among the most aggressive forms of skin cancer. Human formyl peptide receptor (FPR) and its variant FPR-like 1 (FPRL1) have been associated with cell migration and invasiveness in neoplasms. We have studied the in situ expression of these receptors in a large series of melanocytic lesions and correlated the expression with clinicopathological features and prognosis. Tissue microarray blocks of 141 cases including nevi (31 cases), primary (84 cases), and metastatic melanomas (26 cases) were semiquantitatively evaluated by immunohistochemistry for the expression of FPR and FPRL1 proteins. A significant association was observed regarding diagnosis and percentage of cells showing expression of FPR (P = 0.0311) and FPRL1 (P = 0.0053). A gain of FPR immunoreactivity was observed in the lesions having ulceration (P = 0.0194) and Breslow thickness (P = 0.044). Also, high FPRL1 cytoplasmic immunoreactivity was seen in lesions without tumor regression (P = 0.04). In addition, in patients with increased cytoplasmic staining for FPR, the probability of disease-specific survival was significantly lower (log rank test, P = 0.0089). Our findings reveal that FPR and FPRL1 are overexpressed in primary melanoma and correlate with aggressive tumor characteristics, underscoring them as potential therapeutic targets.

BACKGROUND: We explored the use of a novel smart phone-based application (APP) for delivery and monitoring of meditation to treat mood symptoms experienced by cancer patients. METHODS: We assessed the feasibility of using a meditation delivery and tracking APP over 2-weeks and its impact on cancer patients' self-reported anxiety and depression. Outpatients reporting depression and/or anxiety were recruited and randomized to the APP or waitlist control group. Assessments included an expectancy scale, exit survey, mood rating before and after each meditation, and the Edmonton Symptom Assessment Scale (ESAS-FS), Hospital Anxiety and Depression Scale (HADS), and Pittsburgh Sleep Quality Index (PSQI) at baseline and after 2-weeks. The primary aim was to assess feasibility; secondary aims included satisfaction with the APP, association between meditation frequency and length with self-reported symptoms, and change in symptom measures (symptoms, anxiety, depression, and sleep). RESULTS: Our study included 35 participants (17 meditation group; 18 controls) who were primarily female (94%) with breast cancer (60%). The 61% enrollment rate and 71% adherence rate met pre-specified feasibility criteria. Most meditation group participants described the APP as "Useful" to "Very Useful" and would "Probably" or "Definitely" recommend its use. Mixed model analysis revealed a statistically significant association between meditation length (5, 10, or 15 minutes) and change in anxiety, with 15-minute sessions associated with greater reductions in anxiety. In the exit survey, more meditation group vs. control group participants reported improved focus, mood, and sleep. Study groups differed significantly by ESAS fatigue score change; the meditation group decreased a median of 1.5 pts (IQR 2.5) and the control group increased a median of 0.5 points (IQR 2). The meditation group, but not the control group, experienced statistically significant improvement in ESAS fatigue, depression, anxiety, appetite, and physical, psychological, and global distress. Change in PSQI and HADS anxiety and depression scores did not reveal any statistically significant between-group differences. CONCLUSIONS: This pilot study demonstrated the feasibility and acceptability of a meditation APP for cancer patients. Meditation APP users reported improvement in several measures of symptom distress. Future studies should explore ways to enhance the APP's usability and clinical benefit.

INTRODUCTION: Overweight women diagnosed with breast cancer have greater recurrence and mortality risks. Recent studies in advanced cancer showed that the combination of sarcopenia and an overweight or obese body mass index (BMI) is associated with poor clinical outcomes. OBJECTIVES: To compare pathological complete response (pCR) cases with controls and evaluate associations among a pCR, survival outcome, and sarcopenia as well as the combination of both sarcopenia and a BMI ≥25 kg/m(2). METHODS: Sixty-seven breast cancer patients with a pCR to neoadjuvant chemotherapy (NC) were matched with controls who did not have a pCR to NC. Patients were matched by age, Black's nuclear grading system, clinical cancer stage, and estrogen receptor and progesterone receptor status. Body composition was analyzed using computed tomography images taken prior to NC. RESULTS: BMI was associated with pCR. Among normal weight patients, the pCR rate was higher in sarcopenic patients and the progression-free survival (PFS) interval was significantly longer than in overweight or obese BMI patients. The death hazard was 2% higher for each unit higher skeletal muscle index and 0.6% higher for each unit higher visceral adipose tissue. CONCLUSIONS: Overweight patients treated with NC had a lower pCR rate and shorter PFS time. Among patients with a normal BMI, the pCR rate was better in sarcopenic patients. More research is required to evaluate the negative impact of sarcopenic obesity on prognosis and the contributors to better response rates in operable, normal weight breast cancer patients with sarcopenia.
