Purpose: Postmastectomy radiation therapy (PMRT) reduces locoregional recurrence (LRR) and improves overall survival (OS) in patients with breast cancer. Young age has been recognized as a risk factor for LRR. The primary objective of this study was to determine if recommendations for PMRT differed among patients younger than 50 years as compared to women aged 50 years or older., Methods: We reviewed medical records of patients with breast cancer who underwent mastectomy with or without PMRT from 2010 through 2018. Univariable and multivariable models were used to estimate the association of age with PMRT., Results: Of 2471 patients, 839 (34%) were <50 years; 1632 (66%) were ≥50 years. Patients <50 years had a higher percentage of grade 3 tumors, hormone receptor (HR) negative and/or Her-2/neu positive tumors, clinical stage T2/T3 tumors, and nodal involvement. Compared with patients ≥50 years, patients <50 years were more likely to undergo PMRT (OR 1.57; P = .001) and regional node irradiation (RNI) to the internal mammary nodes. Advanced clinical and pathologic stage, invasive tumor histology, the presence of lymphovascular invasion, and treatment with systemic chemotherapy were predictors of PMRT receipt for patients <50 years (P < .05). PMRT was associated with improved OS and recurrence free survival (RFS) among all patients (P < .01)., Conclusion: Patients <50 years were more likely to undergo PMRT and to receive RNI to the internal mammary nodes but were also more likely to have other risk factors for recurrence that would warrant a PMRT recommendation. PMRT improved OS and RFS for all patients., Competing Interests: Disclosure The authors have no relevant financial or non-financial interests to disclose., (Copyright © 2024 Elsevier Inc.

Background: The purpose of this study was to evaluate the delay in initiating adjuvant radiation therapy (RT) after breast-conserving surgery (BCS) in patients with early-stage breast cancer who underwent oncoplastic reduction mammoplasty (ORM) following BCS compared with a matched cohort of patients who did not undergo ORM between BCS and RT., Methods: Medical records of 112 women (56 ORMs and 56 matched non-ORMs) with carcinoma in situ or early-stage breast cancer treated with BCS were reviewed. ORM was performed in a delayed manner following BCS, allowing confirmation of negative surgical margins. Time to RT was defined as time from last oncologic surgery to start of RT., Results: The median follow-up time was 6.8 years for the ORM cohort and 6.7 years for the control non-ORM cohort. Patients who underwent ORM following BCS experienced a significant delay in initiating RT (>8 weeks) than matched patients not undergoing ORM (66% vs. 34%; p < 0.001). Wound complications occurred in 44.6% (n = 25) of patients in the ORM cohort, which were mostly minor, including delayed wound healing and/or infection (39%). There was no significant difference in local recurrence between patients in the non-ORM and ORM cohorts (p = 0.32)., Conclusions: This study demonstrates that ORM following BCS has the potential to delay RT >8 weeks, largely as a result of increased risk of wound complications; however, this delay did not impact local control. ORM can be safely considered for appropriately selected patients with breast cancer., (© 2023. Society of Surgical Oncology.)

Background: There are few quality metrics and benchmarks specific to surgical oncology. Development of a surgeon-level performance metrics system based on peer comparisons is hypothesized to positively influence surgical decision-making. This study established a tracking and reporting system comprised of evidence and consensus-based metrics to assess breast care delivered by individual surgeons., Methods: Surgeons' performance is assessed by a surveillance tracking system of metrics pertaining to referrals and surgical elements. This retrospective analysis of prospectively collected breast care data reports on recurring 6-month and cumulative data from nine care locations from 2015 to 2021., Results: Breast care was provided to 6659 patients by 41 surgeons. A total of 27 breast care metrics were evaluated over 7 years. Metrics with consistent, proficient results were retired after 18 months, including the rate of core biopsy, specimen orientation, and referrals to medical oncology, genetics, and fertility, among others. In clinically node-negative, hormone receptor-positive patients 70 years of age or older, the cumulative rate of sentinel lymph node (SLN) biopsy significantly decreased by 40% over 5.5 years (p < .001). The overall breast conservation rate for T0-T2 cancer increased 10% over 7 years. At the surgeon level, improvements were made in the median number of SLNs removed and in operative note documentation., Conclusions: Implementation of a surgeon-specific, peer comparison-based metric and tracking system has yielded substantive changes in breast care management. This process and governance structure can serve as a model for quantification of breast care at other institutions and for other disease sites., (© 2023 The Authors.

Purpose: Cancer patients are at high risk of developing severe illness from SARS-CoV-2 infection, but risk is lowered with receipt of COVID-19 vaccine. COVID-19 vaccination uptake among previously infected cancer patients may be influenced by an assumption of natural immunity, predicted weak immune response, or concerns about vaccine safety. The objective of this study was to evaluate COVID-19 vaccine uptake trends in cancer patients previously infected with SARS-CoV-2., Materials and Methods: Medical records of 579 sequential cancer patients undergoing active treatment at Levine Cancer Institute who tested positive for COVID-19 between January 2020 and January 2021 were evaluated. Patients who died prior to vaccine eligibility were excluded from the analysis. Demographic, clinical, and COVID-19 related characteristics were analyzed to identify prognostic factors for COVID-19 vaccine uptake as this information could be important for health policy design for future pandemics., Results: Eighty-one patients died prior to the availability of COVID-19 vaccines. The acceptance rate of COVID-19 vaccination among 498 previously infected cancer patients was 54.6%. Of the patients with known vaccination dates, 76.8% received their first vaccine by April 17th, 2021. As of November 30, 2021, 23.7.% of eligible patients were boosted. In univariate models, older age, female sex, higher income, solid tumor cancer type, and hormone therapy were significantly associated with higher vaccine uptake, while Hispanic/Latino ethnicity was significantly associated with lower vaccine uptake. In a multivariable model, age (OR 1.18, 95% CI 1.10-1.28; p < 0.001), female sex (OR 1.80, 95% CI 1.22-2.66; p = 0.003), and higher income (OR 1.11, 95% CI 1.01-1.22; p = 0.032), were predictive of COVID-19 vaccine uptake., Conclusions: Overall, vaccine uptake was low among our cohort of previously infected cancer patients. Older age, female sex, and higher income were the only variables associated with COVID-19 vaccine uptake within this vulnerable patient population., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 Published by Elsevier Ltd.)

The National Surgical Quality Improvement Project (NSQIP) dataset was used to identify perioperative variables associated with the length of stay (LOS) and early discharge among cancer patients undergoing colectomy. Patients who underwent non-emergent right colectomy for colon cancer from 2012 to 2019 were identified from the NSQIP and colectomy-targeted databases. Postoperative LOS was analyzed based on postoperative day (POD) of discharge, with patients grouped into Early Discharge (POD 0-2), Standard Discharge (POD 3-5), or Late Discharge (POD ≥ 6) cohorts. Multivariable ordinal logistic regression was performed to identify risk factors associated with early discharge. The NSQIP query yielded 26,072 patients: 3684 (14%) in the Early Discharge, 13,414 (52%) in the Standard Discharge, and 8974 (34%) in the Late Discharge cohorts. The median LOS was 4.0 days (IQR: 3.0-7.0). Thirty-day readmission rates were 7% for Early Discharge, 8% for Standard Discharge, and 12% for Late Discharge. On multivariable regression analysis, risk factors significantly associated with a shorter LOS included independent functional status, minimally invasive approach, and absence of ostomy or additional bowel resection (all p < 0.001). Perioperative variables can be used to develop a model to identify patients eligible for early discharge after right colectomy for colon cancer. Efforts to decrease the overall median length of stay should focus on optimization of modifiable risk factors.

Background: Neutropenia is the most common adverse event with palbociclib, an oral cyclin-dependent kinase 4/6 inhibitor, with grade 3/4 neutropenia occurring in up to 67% of patients in phase III trials evaluating this agent in metastatic breast cancer. This retrospective chart review assessed characteristics of patients on palbociclib to evaluate for risk factors in the development of grade 3/4 neutropenia., Patients and Methods: Patients with metastatic breast cancer who received palbociclib were included. Patient demographics collected included age, gender, race, body mass index, breast cancer treatment history, palbociclib starting dose, baseline absolute neutrophil count, baseline platelet count, concomitant hormonal therapy, concomitant use of denosumab, and use of concomitant strong CYP3A4 inhibitors/inducers. Events of interest occurring within 30 days of initiation of palbociclib were also noted including antibiotic and corticosteroid use, mucosal conditions, open wounds, or surgery. The incidence and potential risk factors for grade 3/4 neutropenia in the first 6 months of treatment were analyzed., Results: A total of 257 patients were included in the analysis with 206 patients (80.2%) and 139 patients (54.1%) experiencing all-grade neutropenia and grade 3/4 neutropenia, respectively. Multivariate analysis found baseline myelosuppression and recent antibiotic use to be independent predictors of grade 3/4 neutropenia. Normal weight patients had an increased risk for grade 3/4 neutropenia compared to obese patients by multivariate analysis., Conclusion: The results of this study showed baseline myelosuppression and recent antibiotic use within 30 days of palbociclib initiation were predictive of a higher incidence of grade 3/4 neutropenia. Obese patients were less likely to develop grade 3/4 neutropenia compared to normal weight patients., (© 2022.

Objective: United States oncology trends consistently demonstrate that nearly half of T4a larynx carcinoma patients are treated with larynx preservation, despite national guidelines favoring laryngectomy. This study identifies clinical decision-making drivers and defines patient subsets that should become targets for care improvement., Methods: Retrospective analysis of patients with cT4 squamous cell carcinoma of the larynx from US National Cancer Database 2005-2016. Demographic data and survival rates between clinical pathways were compared. Survival was estimated by Kaplan-Meier method with statistical comparisons assessed by log-rank test., Results: Of 11,556 patients with cT4 disease, laryngectomy (TL) was the initial treatment for 4627 (40%) patients. Larynx preservation via chemoradiation (CRT) occurred for 4307 patients. TL and CRT patients had similar Charlson-Deyo comorbidity indices and insurance status. TL patients had higher total tumor size, lower N3 rates and were more often seen at academic institutions ( p  < .0001). N0 surgery patients with adjuvant treatment demonstrated superior median survival (MS) compared to CRT (surgery + radiation MS: 69 months, surgery + chemoradiation MS: 66, CRT MS: 37.7), p  < .0001. MS for N1/N2 disease patients was 56.5 months for surgery + radiation and 35.5 months for surgery + CRT, superior to CRT, MS 30.8 months, p  < .0001. Tri-modality N3 patients with up front surgery had similar MS compared to CRT (surgery + chemoradiation 21.3 months vs. CRT 16.1), p  = .95., Conclusion: National quality improvement initiatives are needed to promote guideline adherence and improve survival in advanced larynx cancer. Targets for such initiatives should be patients with limited or no nodal disease burden, that meet clear T4a imaging criteria., Level of Evidence: Level IV, non-randomized controlled cohort., Competing Interests: The authors have no relevant conflicts of interest to disclose., (© 2022 The Authors.

Background/aim: Survivorship care programs (SCPs) educate patients on post-treatment side-effects, which may lead to earlier identification and mitigation of their impact. This study assessed the impact of SCP on identification and management of post-treatment hypothyroidism in a head and neck cancer population and evaluated socio-demographic factors in the effectiveness of SCPs., Patients and Methods: A retrospective analysis was performed of sociodemographic and clinical characteristics of patients with head and neck cancer treated with radiation therapy between January 2011 and January 2019 at a large community cancer institution. Development of hypothyroidism was defined as elevated thyroid-stimulating hormone (TSH) or initiation of supplementation post-treatment. Cumulative incidence of hypothyroidism was analyzed with Gray's method., Results: Of 608 patients, 483 (79%) had post-treatment TSH surveillance. A total of 203 (42%) of those patients developed hypothyroidism; 53 (11%) patients completed SCPs. The median follow-up was 1.4 (interquartile range=0.7-2.6) years with a median time until diagnosis of hypothyroidism of 1.2 (interquartile range=0.7-2.1) years. The median time to diagnosis was 12.0 months with SCP versus 14.2 months without. Race and insurance status were not associated with differences in thyroid surveillance. Patients with laryngeal cancer were at greatest risk of developing hypothyroidism (hazard ratio=1.92, confidence interval=1.44-2.56; p<0.077). Cumulative incidence of post-treatment hypothyroidism was higher in patients managed with SCP, 65.4% at 4 years, compared to those without (49.0%). Receipt of SCP was independently associated with an increased incidence of hypothyroidism detection (hazard ratio=1.51, confidence interval=1.04-2.20; p=0.030)., Conclusion: In our experience, SCP utilization was independently associated with a diagnosis of hypothyroidism. This study supports implementation of a survivorship program for identification and management of post-treatment sequelae., (Copyright © 2022 International Institute of Anticancer Research (Dr. George J.

Introduction: Co-surgeon approach for bilateral mastectomy may lead to shorter operative times and improved outcomes compared with single-surgeon approach, but cost differences remain unclear. Economic models were applied to determine whether either approach offered a lower cost opportunity., Methods: A retrospective review of 409 patients undergoing single-surgeon or co-surgeon bilateral mastectomy between January 1, 2010 through April 30, 2016 was conducted. Outcomes included narcotic and antinausea doses, length of stay (LOS), and operative time. Analyses stratified by reconstruction and no reconstruction included Wilcoxon tests, Poisson regression, generalized linear models, and a cost calculator., Results: Of 409 patients, 310 had reconstruction and 99 had no reconstruction. Compared with single-surgeon approach, co-surgeon approach was associated with less operative time and shorter LOS (233 vs. 250 min and 1.0 vs. 1.8 days no reconstruction; and 429 vs. 493 min and 2.2 vs. 2.8 days reconstruction). Economic analysis demonstrated less operative time, shorter LOS, and lower average cost for co-surgeon approach ($32,400 vs. $34,400 no reconstruction; and $76,700 vs. $79,400 reconstruction)., Conclusion: Compared with the single-surgeon, the co-surgeon approach with reconstruction was associated with a statistically significant decrease in operative time and LOS. Economic analysis estimated the co-surgeon approach could lead to lower costs., (© 2022 Wiley Periodicals LLC.)

Background: Prognostic nomograms for patients with resected extremity soft tissue sarcoma (STS) include the Sarculator and Memorial Sloan Kettering (MSKCC) nomograms. We sought to validate these two nomograms within a large, modern, multi-institutional cohort of resected primary extremity STS patients., Methods: Resected primary extremity STS patients from 2000 to 2017 were identified across nine high-volume U.S. institutions. Predicted 5- and 10-year overall survival (OS) and distant metastases cumulative incidence (DMCI), and 4-, 8-, and 12-year disease-specific survival (DSS) were calculated with Sarculator and MSKCC nomograms, respectively. Predicted survival probabilities stratified in quintiles were compared in calibration plots to observed survival assessed by Kaplan-Meier estimates. Cumulative incidence was estimated for DMCI. Harrell's concordance index (C-index) assessed discriminative ability of nomograms., Results: A total of 1326 patients underwent resection of primary extremity STS. Common histologies included: undifferentiated pleomorphic sarcoma (35%), fibrosarcoma (13%), and leiomyosarcoma (9%). Median tumor size was 8.0 cm (IQR 4.5-13.0). Tumor grade distribution was: Grade 1 (13%), Grade 2 (9%), Grade 3 (78%). Median OS was 172 months, with estimated 5- and 10-year OS of 70% and 58%. C-indices for 5- and 10-year OS (Sarculator) were 0.72 (95% CI 0.70-0.75) and 0.73 (95% CI 0.70-0.75), and 0.72 (95% CI 0.69-0.75) for 5- and 10-year DMCI. C-indices for 4-, 8-, and 12-year DSS (MSKCC) were 0.71 (95% CI 0.68-0.75). Calibration plots showed good prognostication across all outcomes., Conclusions: Sarculator and MSKCC nomograms demonstrated good prognostic ability for survival and recurrence outcomes in a modern, multi-institutional validation cohort of resected primary extremity STS patients. External validation of these nomograms supports their ongoing incorporation into clinical practice., (© 2022. Society of Surgical Oncology.)

Background: Low socioeconomic status (SES) has been linked to worse survival in patients with colorectal cancer (CRC); however, the impact of SES on early-onset CRC remains undescribed., Materials and Methods: Retrospective analysis of data from the National Cancer Database (NCDB) between 2004 and 2016 was conducted. We combined income and education to form a composite measure of SES. Logistic regression and χ 2 testing were used to examine early-onset CRC according to SES group. Survival rates and Cox proportional hazards models compared stage-specific overall survival (OS) between the SES groups., Results: In total, 30,903 patients with early-onset CRC were identified, of whom 78.7% were White; 14.5% were Black. Low SES compared with high SES patients were more likely to be Black (26.3% vs. 6.1%) or Hispanic (25.3% vs. 10.5%), have T4 tumors (21.3% vs. 17.8%) and/or N2 disease (13% vs. 11.1%), and present with stage IV disease (32.8% vs. 27.7%) at diagnosis (p < .0001, all comparisons). OS gradually improved with increasing SES at all disease stages (p < .001). In stage IV, the 5-year survival rate was 13.9% vs. 21.7% for patients with low compared with high SES. In multivariable analysis, SES (low vs. high group; adjusted hazard ratio [HR adj ], 1.35; 95% confidence interval [CI], 1.26-1.46) was found to have a significant effect on survival (p < .0001) when all of the confounding variables were adjusted. Insurance (not private vs. private; HR adj , 1.38; 95% CI, 1.31-1.44) mediates 31% of the SES effect on survival., Conclusion: Patients with early-onset CRC with low SES had the worst outcomes. Our data suggest that SES should be considered when implementing programs to improve the early detection and treatment of patients with early-onset CRC., Implications for Practice: Low socioeconomic status (SES) has been linked to worse survival in patients with colorectal cancer (CRC); however, the impact of SES on early-onset CRC remains undescribed. In this retrospective study of 30,903 patients with early-onset CRC in the National Cancer Database, a steady increase in the yearly rate of stage IV diagnosis at presentation was observed. The risk of death increased as socioeconomic status decreased. Race and insurance status were independent predictors for survival. Implementation of programs to improve access to care and early diagnostic strategies among younger adults, especially those with low SES, is warranted., (© 2021 The Authors.

Background and Objectives: Prognostic nomograms for patients undergoing resection of retroperitoneal sarcoma (RPS) include the Sarculator and Memorial Sloan Kettering (MSK) sarcoma nomograms. We sought to validate the Sarculator and MSK nomograms within a large, modern multi-institutional cohort of patients with primary RPS undergoing resection., Methods: Patients who underwent resection of primary RPS between 2000 and 2017 across nine high-volume US institutions were identified. Predicted 7-year disease-free (DFS) and overall survival (OS) and 4-, 8-, and 12-year disease-specific survival (DSS) were calculated from the Sarculator and MSK nomograms, respectively. Nomogram-predicted survival probabilities were stratified in quintiles and compared in calibration plots to observed survival outcomes assessed by Kaplan-Meier estimates. Discriminative ability of nomograms was quantified by Harrell's concordance index (C-index)., Results: Five hundred and two patients underwent resection of primary RPS. Histologies included leiomyosarcoma (30%), dedifferentiated liposarcoma (23%), and well-differentiated liposarcoma (15%). Median tumor size was 14.0 cm (interquartile range [IQR], 8.5-21.0 cm). Tumor grade distribution was: Grade 1 (27%), Grade 2 (17%), and Grade 3 (56%). Median DFS was 31.5 months; 7-year DFS was 29%. Median OS was 93.8 months; 7-year OS was 51%. C-indices for 7-year DFS, and OS by the Sarculator nomogram were 0.65 (95% confidence interval [CI]: 0.62-0.69) and 0.69 (95%CI: 0.65-0.73); plots demonstrated good calibration for predicting 7-year outcomes. The C-index for 4-, 8-, and 12-year DSS by the MSK nomogram was 0.71 (95%CI: 0.67-0.75); plots demonstrated similarly good calibration ability., Conclusions: In a diverse, modern validation cohort of patients with resected primary RPS, both Sarculator and MSK nomograms demonstrated good prognostic ability, supporting their ongoing adoption into clinical practice., (© 2021 Wiley Periodicals LLC.)

Purpose: Little is known about the use of palliative and hospice care and their impact on healthcare utilization near the end of life (EOL) in early-onset pancreatic cancer (EOPC)., Methods: Patients with EOPC (≤ 50 years) were identified using the institutional tumor registry for years 2011-2018, and demographic, clinical, and rates of referral to palliative and hospice services were obtained retrospectively. Predictors of healthcare utilization, defined as use of ≥ 1 emergency department (ED) visit or hospitalization within 30 days of death, place of death (non-hospital vs. hospital), and time from last chemotherapy administration prior to death, were assessed using descriptive, univariable, and multivariable analyses including chi-square and logistic regression models., Results: A total of 112 patients with EOPC with a median age of 46 years (range, 29-50) were studied. Forty-four percent were female, 28% were Black, and 45% had metastatic disease. Fifty-seven percent received palliative care at a median of 7.8 weeks (range 0-265) following diagnosis. The median time between last chemotherapy and death was 7.9 weeks (range 0-102). Seventy-four percent used hospice services prior to death for a median of 15 days (range 0-241). Rate of healthcare utilization at the EOL was 74% in the overall population. Black race and late use of chemotherapy were independently associated with increase in ED visits/hospitalization and hospital place of death., Conclusions: Although we observed early referrals to palliative care among patients with newly diagnosed EOPC, short duration of hospice enrollment and rates of healthcare utilization prior to death were substantial.

Introduction: The National Comprehensive Cancer Network (NCCN) developed clinical practice guidelines for germline pathogenic variants in highly penetrant genes, such as TP53 and PTEN, and in moderately penetrant genes, such as CHEK2, ATM and PALB2. Whether the practice of radiographic surveillance of patients with pathogenic variants in genes other than BRCA1/2 complies with current NCCN guidelines remains unclear., Methods: Retrospective review of patients identified with pathogenic variants in genes other than BRCA1/2 from 2007 through 2017 to determine if radiographic surveillance was in accordance with NCCN guidelines for mammography and consideration of magnetic resonance imaging (MRI). Exclusions included variants of unknown significance, pathogenic variants not associated with an increased risk of breast cancer, and previous breast cancer diagnosis., Results: After exclusions, 35 patients with pathogenic variants in ATM, CDH1, CHEK2, NBN, PALB2, PTEN, and STK11 genes were reviewed to assess whether radiographic surveillance was in accordance with NCCN guidelines. Guidelines for those with variants in ATM, CHEK2 and NBN includes annual mammography with tomosynthesis and consideration of breast MRI at age 40, variants in CDH1 and PALB2 at age 30, variants in PTEN at age 30-35 or 5-10 years before the earliest family breast cancer, and variants in STK11 at age 25. Of these 35 patients, 11 (31%) received mammography only; 11 (31%) received mammography and MRI, and 13 (37%) received no radiographic surveillance. Two of the 35 (6%) patients who received radiographic surveillance were diagnosed with ductal carcinoma in situ or invasive breast cancer., Conclusion: Thirty-one percent of patients with pathogenic variants in genes other than BRCA1/2 received both mammography and MRI. Thirty-seven percent of patients with these highly penetrant and moderately penetrant genes received no radiographic follow-up, clearly demonstrating an opportunity for improvement.

There has been increasing utilization of minimally invasive surgical approaches. This study evaluates the effect of surgical approach on total lymph node harvest in gastrectomy. Patients undergoing gastrectomy for gastric adenocarcinoma between 2007 and 2018 were reviewed retrospectively. Data collected included age, gender, race, BMI, neoadjuvant therapy, tumor stage, surgical approach, and total number of lymph nodes harvested. The total number of harvested lymph nodes for open, laparoscopic, and robotic gastrectomy was compared using the Kruskal-Wallis test for univariate analysis and a Poisson regression model for multivariable analysis. One hundred four patients were identified. Median node harvest for open, laparoscopic, and robotic approaches were 16, 17, and 36, respectively. Multivariable analysis controlling for gender, BMI, pathological T stage, and year of operation demonstrates that surgical approach is statistically significantly associated with lymph node harvest ( F = 83.4, P < 0.0001). In multivariable analysis, robotic approach was associated with greater lymph node harvest than both open ( P < 0.0001) and laparoscopic ( P < 0.0001) approaches, whereas laparoscopic approach was associated with greater lymph node harvest than open ( P < 0.0001) approach. These data demonstrate that for patients undergoing gastrectomy for gastric adenocarcinoma at our institution, robotic approach is associated with greater lymph node harvest than both laparoscopic and open approaches.

Some authors report that patients receiving neoadjuvant chemotherapy have fewer lymph nodes harvested during axillary dissection and more dissections with < 10 nodes compared with patients who undergo surgery initially. We sought to determine whether there was a difference between these patient groups in terms of number of nodes harvested and number of dissections with < 10 nodes. Retrospective review of 258 patients diagnosed with breast cancer who underwent an axillary lymph node dissection between July 1, 2015, and December 31, 2017 was performed. Chi-squared test was used to assess differences between patient groups. Of 258 patients undergoing dissection, 48 per cent received neoadjuvant chemotherapy; 52 per cent underwent surgery as first therapeutic intervention. Mean number of nodes resected; 14.3 + 6.3 for patients with no prior chemotherapy versus 14.9 + 6.6 for patients with neoadjuvant chemotherapy ( P = 0.48). For patients undergoing surgery as first intervention, 21 per cent had < 10 nodes harvested. For patients receiving neoadjuvant chemotherapy, 20 per cent had < 10 nodes harvested. Patients who received neoadjuvant chemotherapy showed no statistically significant difference in the number of lymph nodes harvested during axillary dissection compared with patients undergoing surgery as first intervention. Neoadjuvant chemotherapy does not reduce the node harvest at the time of axillary dissection.

Background: Optimal nutrition after esophagectomy is challenging due to alterations in eating, both from the tumor and during surgical recovery. Enteral nutrition via feeding tube is commonly used. The impact of feeding tubes on post-esophagectomy outcomes was examined in a large national data set., Methods: Patients with esophageal cancer (1998-2013) undergoing esophagectomy were extracted from the Surveillance Epidemiology and End Results-Medicare database. Chi-square and t tests were used to compare categorical and continuous variables. Time trend analyses were performed with Cochran-Armitage survival using log-rank and multivariable analysis with generalized linear modeling., Results: The study examined 2495 patients. The majority had enteral feeding access (71%, n = 1794) during the perioperative period. Mortality among the patients with feeding tubes was lower at 30 days (5.4% vs 8.4%), 60 days (9.0% vs 13.0%), and 90 days (12.2% vs 15.8%). In the multivariable analysis, the patients with feeding tubes had improved short-term survival at 30 days (odds ratio [OR], 0.65, 95% confidence interval [CI], 0.46-0.93), 60 days (OR, 0.64; 95% CI, 0.49-0.85), and 90 days (OR, 0.70; 95% CI, 0.54-0.90). The hospital stay was shorter for the patients undergoing enteral feeding tube placement (17.9 vs 19.5 days; p = 0.04). Discharge destination (home vs health care facility) showed no difference., Conclusions: Feeding tubes in patients undergoing esophagectomy were associated with an increase in short-term survival up to 90 days after surgery. Feeding tube placement was not associated with higher rates of non-home discharges and did not prolong the hospital stay.

Purpose: Radial scars (RS) commonly present mammographically as architectural distortions, but these lesions may be associated with non-invasive and invasive breast cancer. Digital breast tomosynthesis (DBT) has resulted in higher detection rates of architectural distortion particularly in patients with dense breast tissue. We hypothesized that rates of clinically relevant lesions confirmed surgically would be lower in patients who received DBT imaging compared with those who received standard digital breast imaging., Methods: We performed a retrospective review of 223 patients diagnosed with pure RS by core biopsy and surgical excision before and after DBT was introduced. The rate of upgrading to malignancy or high-risk lesion was evaluated. Demographics, biopsy type, and histologic data were analyzed. Univariable logistic regression analysis was used to identify variables that may be associated with upgrading., Results: The rate of identifying RS increased from 0.04-.13% (P < 0.0001) with DBT imaging. The upgrade rate on surgical specimen to invasive or non-invasive cancer was similar before and after DBT; 6% versus 3%, as were findings of a high-risk lesion; 12% versus 22%. No predictive factors were identified for patients upgraded to malignant neoplasms or high-risk lesions., Conclusions: The likelihood of identifying RS has increased with DBT imaging, but rates of upgrading to a malignant neoplasm or high-risk lesion were similar to those before DBT. Although the rate of upgrading to malignancy after DBT was low, an excisional biopsy should be considered as 22% of patients were upgraded to high-risk lesions. These patients are candidates for chemoprevention and/or high-risk surveillance.

Patients receiving immunosuppressive cancer treatments in settings where there is a high degree of human-animal interaction may be at increased risk for opportunistic zoonotic infections or reactivation of latent infections. We sought to determine the seroprevalence of selected zoonotic pathogens among patients diagnosed with haematologic malignancies and undergoing chemotherapeutic treatments in Romania, where much of the general population lives and/or works in contact with livestock. A convenience sample of 51 patients with haematologic cancer undergoing chemotherapy at a referral clinic in Cluj-Napoca, Romania, was surveyed regarding animal exposures. Blood samples were obtained and tested for evidence of infection with Bartonella species, Coxiella burnetii and Toxoplasma gondii, which are important opportunistic zoonotic agents in immunocompromised individuals. 58.8% of participants reported living or working on a farm, and living or working on a farm was associated with contact with livestock and other animals. 37.5% of participants were IgG seroreactive against one or more of five Bartonella antigens, and seroreactivity was statistically associated with living on farms. Farm dwellers were 3.6 times more likely to test IgG seroreactive to Bartonella antibodies than non-farm dwellers. 47.1% of the participants tested T. gondii IgG positive and 13.7% tested C. burnetii IgG positive, indicating past or latent infection. C. burnetii IgM antibodies were detected in four participants (7.8%), indicating possible recent infection. These results indicate that a large proportion of patients with haematologic cancer in Romania may be at risk for zoonotic infections or for reactivation of latent zoonotic infections, particularly with respect to Bartonella species. Special attention should be paid to cancer patients' exposure to livestock and companion animals in areas where much of the population lives in rural settings., (© 2017 Blackwell Verlag GmbH.)

Background: Little is known about the environmental and public health impact of unconventional natural gas extraction activities, including hydraulic fracturing, that occur near residential areas., Objectives: Our aim was to assess the relationship between household proximity to natural gas wells and reported health symptoms., Methods: We conducted a hypothesis-generating health symptom survey of 492 persons in 180 randomly selected households with ground-fed wells in an area of active natural gas drilling. Gas well proximity for each household was compared with the prevalence and frequency of reported dermal, respiratory, gastrointestinal, cardiovascular, and neurological symptoms., Results: The number of reported health symptoms per person was higher among residents living < 1 km (mean ± SD, 3.27 ± 3.72) compared with > 2 km from the nearest gas well (mean ± SD, 1.60 ± 2.14; p = 0.0002). In a model that adjusted for age, sex, household education, smoking, awareness of environmental risk, work type, and animals in house, reported skin conditions were more common in households < 1 km compared with > 2 km from the nearest gas well (odds ratio = 4.1; 95% CI: 1.4, 12.3; p = 0.01). Upper respiratory symptoms were also more frequently reported in persons living in households < 1 km from gas wells (39%) compared with households 1-2 km or > 2 km from the nearest well (31 and 18%, respectively) (p = 0.004). No equivalent correlation was found between well proximity and other reported groups of respiratory, neurological, cardiovascular, or gastrointestinal conditions., Conclusion: Although these results should be viewed as hypothesis generating, and the population studied was limited to households with a ground-fed water supply, proximity of natural gas wells may be associated with the prevalence of health symptoms including dermal and respiratory conditions in residents living near natural gas extraction activities. Further study of these associations, including the role of specific air and water exposures, is warranted.

Natural gas extraction activities, including the use of horizontal drilling and hydraulic fracturing, may pose potential health risks to both human and animal populations in close proximity to sites of extraction activity. Because animals may have increased exposure to contaminated water and air as well as increased susceptibility to contaminant exposures compared to nearby humans, animal disease events in communities living near natural gas extraction may provide "sentinel" information useful for human health risk assessment. Community health evaluations as well as health impact assessments (HIAs) of natural gas exploration should therefore consider the inclusion of animal health metrics in their assessment process. We report on a community environmental health survey conducted in an area of active natural gas drilling, which included the collection of health data on 2452 companion and backyard animals residing in 157 randomly-selected households of Washington County, Pennsylvania (USA). There were a total of 127 reported health conditions, most commonly among dogs. When reports from all animals were considered, there were no significant associations between reported health condition and household proximity to natural gas wells. When dogs were analyzed separately, we found an elevated risk of 'any' reported health condition in households less than 1km from the nearest gas well (OR = 3.2, 95% CI 1.07-9.7), with dermal conditions being the most common of canine disorders. While these results should be considered hypothesis generating and preliminary, they suggest value in ongoing assessments of pet dogs as well as other animals to better elucidate the health impacts of natural gas extraction on nearby communities.

Objective: Family accommodation of patients with obsessive-compulsive disorder, i.e., participation in symptoms and modification of personal and family routines, was assessed in relation to family stress, functioning, and attitudes toward the patient., Method: Primary caretakers for 34 patients with obsessive-compulsive disorder were interviewed to assess the nature and frequency of accommodating behaviors. The caretakers also completed several measures of family functioning., Results: Of the 34 spouses or parents, 30 (88.2%) reported accommodating the patient. Family accommodation correlated with poor family functioning, rejecting attitudes toward the patient, and several types of family stress., Conclusions: Family accommodation of patients with obsessive-compulsive disorder was associated with global family dysfunction and stress. This study suggests that families' efforts to accommodate patients may be intended to reduce patient anxiety or anger directed at relatives.

Patients with obsessive-compulsive disorder may experience severely disabling symptoms and require hospitalization. Based on treatment of 77 such patients admitted to a long-term general psychiatric research unit over a seven-year period, the authors present pharmacologic, psychosocial, and behavioral management strategies for treating these patients on general psychiatric units. The treatment guidelines require only modest modifications of standard practice and can be adapted for use on general units without specialized staff training. Some patients with obsessive-compulsive disorder exhibit strong control and dependency needs and disrupt the milieu in characteristic ways. These patients may generate conflict among staff about whether the patients can control obsessive-compulsive behaviors; they may anger other patients because of the large amount of staff attention they demand. Educating staff about obsessive-compulsive patients' control and dependency needs and enlisting the support of fellow patients can improve the milieu.
