RESUMEN
BACKGROUND AND METHODS: Although signet ring cell (SRC) histology is associated with resistance to neoadjuvant chemoradiotherapy and worse overall survival (OS) in esophageal adenocarcinoma (EAC), its prognostic relationship among patients who survive the early period following resection is unknown. EAC patients who underwent trimodality therapy at a single institution (2006-2018) were identified. Bayesian multivariable regression (BMR) analyses of OS and additional OS from a 3-year landmark were performed. RESULTS: Of 631 patients, SRCs were present in 16.0% (N = 101). SRC was associated with shorter median OS (45.8 [95% confidence interval: 31.0-96.7] vs. 79.8 [63.0-107.2] months; p = 0.014). In BMR analysis, the absence of an SRC component was moderately associated with improved OS (probability of beneficial effect, PBE = 0.879). Three-year conditional BMR analysis of additional OS (N = 357) showed that SRC status no longer had a prognostic effect (PBE = 0.546); higher pathological stage was strongly associated with worse additional OS (PBE < 0.001). CONCLUSIONS: The presence of SRC portends worse OS following trimodality therapy for EAC. However, this prognostic impact is dynamic and abates by 3 years postoperatively. In contrast, a higher pathological stage is strongly associated with poor overall and 3-year conditional survival. DISCUSSION: These findings may inform postoperative patient counseling and surveillance protocols.
RESUMEN
BACKGROUND: In advanced osteosarcoma, the lung is the most frequent site of distant metastasis, with metastasectomy often used for local disease control. The influence of pulmonary resection margin length on outcomes for osteosarcoma has not been well explored. This study sought to evaluate the impact of margin length relative to tumor size on local recurrence and survival in lung-limited metastatic osteosarcoma. METHODS: Patients with metastatic osteosarcoma who underwent lung resection between 2000 and 2020 were identified from a single institution. Clinicopathologic variables were collected. The margin length-to-tumor size ratio (MTR) was calculated per nodule and classified relative to an MTR of 0.5. The primary outcome was development of local recurrence per nodule. Multivariate logistic regression was used to investigate covariates. RESULTS: A total of 142 patients with 689 nodules met inclusion criteria, with mean age of 35.6 years (interquartile range [IQR], 20.9-46.6 years). Patients were predominantly male (n = 87; 61.3%) and White (n = 106; 72.5%). Most nodules (n = 644; 93.5%) were resected through thoracotomy. The mean tumor size was 0.8 cm (IQR, 0.5-1.70 cm), with an average margin length of 0.3 cm (IQR, 0.1-0.7 cm). Among all nodules, 299 (43.4%) had an MTR >0.5. Systemic therapy was received by 94 patients (66.2%) preoperatively and by 100 patients (70.4%) postoperatively. Importantly, the study found that an MTR >0.5 conferred a protective effect against disease recurrence (hazard ratio, 0.67; 95% CI, 0.52-0.87; P = .003). CONCLUSIONS: In resected pulmonary metastatic osteosarcoma, a margin length greater than one-half the size of the pulmonary nodule is associated with a lower incidence of local disease recurrence. This finding has implications for the subsequent need for additional therapy and disease-free status, thus meriting attentive intraoperative consideration.
RESUMEN
Esophageal cancer is the seventh most common malignancy worldwide, with over 470 000 new cases diagnosed each year. Two distinct histological subtypes predominate, and should be considered biologically separate disease entities.1 These subtypes are esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC). Outcomes remain poor regardless of subtype, with most patients presenting with late stage disease.2 Novel strategies to improve early detection of the respective precursor lesions, squamous dysplasia, and Barrett's esophagus offer the potential to improve outcomes. The introduction of a limited number of biologic agents, as well as immune checkpoint inhibitors, is resulting in improvements in the systemic treatment of locally advanced and metastatic esophageal cancer. These developments, coupled with improvements in minimally invasive surgical and endoscopic treatment approaches, as well as adaptive and precision radiotherapy technologies, offer the potential to improve outcomes still further. This review summarizes the latest advances in the diagnosis and management of esophageal cancer, and the developments in understanding of the biology of this disease.

Purpose: The effectiveness of intensity-modulated proton therapy (IMPT) for esophageal cancer treated with definitive concurrent chemoradiation therapy remains inadequately explored. We investigated long-term outcomes and toxicity experienced by patients who received IMPT as part of definitive esophageal cancer treatment. Patients and Methods: We retrospectively identified and analyzed 34 patients with locally advanced esophageal cancer who received IMPT with concurrent chemotherapy as a definitive treatment regimen at The University of Texas MD Anderson Cancer Center from 2011 to 2021. The median IMPT dose was 50.4 GyRBE in 28 fractions; concurrent chemotherapy consisted of fluorouracil and/or taxane and/or platinum. Survival outcomes were determined by the Kaplan-Meier method, and toxicity was scored according to the Common Terminology Criteria for Adverse Events version 4.0. Results: The median age of all patients was 71.5 years. Most patients had stage III (cT3 cM0) adenocarcinoma of the lower esophagus. At a median follow-up time of 39 months, the 5-year overall survival rate was 41.1%; progression-free survival, 34.6%; local regional recurrence-free survival, 78.1%; and distant metastasis-free survival, 65.0%. Common acute chemoradiation therapy-related toxicities included hematologic toxicity, esophagitis (and late-onset), fatigue, weight loss, and nausea (and late-onset); grade 3 toxicity rates were 26.0% for hematologic, 18.0% for esophagitis and 9.0% for nausea. No patient had grade ≥3 wt loss or radiation pneumonitis, and no patients had pulmonary fibrosis or esophageal fistula. No grade ≥4 events were observed except for hematologic toxicity (lymphopenia) in 2 patients. Conclusion: Long-term survival and toxicity were excellent after IMPT for locally advanced esophageal cancer treated definitively with concurrent chemoradiation therapy. When available, IMPT should be offered to such patients to minimize treatment-related cardiopulmonary toxicity without sacrificing outcomes.
RESUMEN
Purpose: Evidence suggests that proton-beam therapy (PBT) results in less toxicity and postoperative complications compared to photon-based radiotherapy in patients who receive chemoradiotherapy followed by esophagectomy for cancer. Ninety-day mortality (90DM) is an important measure of the postoperative (nononcologic) outcome as proxy of quality-of-care. We hypothesize that PBT could reduce 90DM compared to photon-based radiotherapy. Materials and Methods: From a single-center retrospective database patients treated with chemoradiotherapy before esophagectomy for cancer were selected (1998-2022). Univariable logistic regression was used to study the association of radiotherapy modality with 90DM. Three separate methods were applied to adjust for confounding bias, including multivariable logistic regression, propensity score matching, and inverse probability of treatment weighting. Stratified analysis for the age threshold that maximized the difference in 90DM (ie, ≥67 vs <67 years) was performed. Results: A total of 894 eligible patients were included and 90DM was 5/202 (2.5%) in the PBT versus 29/692 (4.2%) in the photon-based radiotherapy group (P = .262). After adjustment for age and tumor location, PBT versus photon-based radiotherapy was not significantly associated with 90DM (P = .491). The 90DM was not significantly different for PBT versus photon-based radiotherapy in the propensity score matching (P = .379) and inverse probability of treatment weighting cohort (P = .426). The stratified analysis revealed that in patients aged ≥67 years, PBT was associated with decreased 90DM (1.3% vs 8.8%; P = .026). Higher age significantly increased 90DM risk within the photon-based radiotherapy (8.8% vs 2.7%; P = .001), but not within the PBT group (1.3% vs 3.2%; P = .651). Conclusion: No statistically significant difference was observed in postoperative 90DM after esophagectomy for cancer between PBT and photon-based neoadjuvant chemoradiotherapy. However, among older patients a signal was observed that PBT may reduce 90DM risk.
RESUMEN
BACKGROUND: Small extracellular vesicle (sEV) analysis can potentially improve cancer detection and diagnostics. However, this potential has been constrained by insufficient sensitivity, dynamic range, and the need for complex labeling. METHODS: In this study, we demonstrate the combination of PANORAMA and fluorescence imaging for single sEV analysis. The co-acquisition of PANORAMA and fluorescence images enables label-free visualization, enumeration, size determination, and enables detection of cargo microRNAs (miRs). RESULTS: An increased sEV count is observed in human plasma samples from patients with cancer, regardless of cancer type. The cargo miR-21 provides molecular specificity within the same sEV population at the single unit level, which pinpoints the sEVs subset of cancer origin. Using cancer cells-implanted animals, cancer-specific sEVs from 20 µl of plasma can be detected before tumors were palpable. The level plateaus between 5-15 absolute sEV count (ASC) per µl with tumors ≥8 mm3. In healthy human individuals (N = 106), the levels are on average 1.5 ASC/µl (+/- 0.95) without miR-21 expression. However, for stage I-III cancer patients (N = 205), nearly all (204 out of 205) have levels exceeding 3.5 ASC/µl with an average of 12.2 ASC/µl (±9.6), and a variable proportion of miR-21 labeling among different tumor types with 100% cancer specificity. Using a threshold of 3.5 ASC/µl to test a separate sample set in a blinded fashion yields accurate classification of healthy individuals from cancer patients. CONCLUSIONS: Our techniques and findings can impact the understanding of cancer biology and the development of new cancer detection and diagnostic technologies.
Small extracellular vesicles (sEVs) are tiny particles derived from cells that can be detected in bodily fluids such as blood. Detecting sEVs and analyzing their contents may potentially help us to diagnose disease, for example by observing differences in sEV numbers or contents in the blood of patients with cancer versus healthy people. Here, we combine two imaging methods our previously developed method PANORAMA and imaging of fluorescence emitted by sEVsto visualize and count sEVs, determine their size, and analyze their cargo. We observe differences in sEV numbers and cargo in samples taken from healthy people versus people with cancer and are able to differentiate these two populations based on our analysis of sEVs. With further testing, our approach may be a useful tool for cancer diagnosis and provide insights into the biology of cancer and sEVs.
RESUMEN
OBJECTIVE: To investigate overall survival and length of stay (LOS) associated with differing management for high output (>1 L over 24 hours) leaks (HOCL) after cancer-related esophagectomy. BACKGROUND: Although infrequent, chyle leak after esophagectomy is an event that can lead to significant perioperative sequelae. Low-volume leaks appear to respond to nonoperative measures, whereas HOCLs often require invasive therapeutic interventions. METHODS: From a prospective single-institution database, we retrospectively reviewed patients treated from 2001 to 2021 who underwent esophagectomy for esophageal cancer. Within that cohort, we focused on a subgroup of patients who manifested a HOCL postoperatively. Clinicopathologic and operative characteristics were collected, including hospital LOS and survival data. RESULTS: A total of 53/2299 patients manifested a HOCL. These were mostly males (77%), with a mean age of 62 years. Of this group, 15 patients received nonoperative management, 15 patients received prompt (<72 hours from diagnosis) interventional management, and 23 received late interventional management. Patients in the late intervention group had longer LOSs compared with early intervention (slope = 9.849, 95% CI: 3.431-16.267). Late intervention (hazard ratio: 4.772, CI: 1.384-16.460) and nonoperative management (hazard ratio: 4.731, CI: 1.294-17.305) were associated with increased mortality compared with early intervention. Patients with early intervention for HOCL had an overall survival similar to patients without chyle leaks in survival analysis. CONCLUSIONS: Patients with HOCL should receive early intervention to possibly reverse the prognostic implications of this potentially detrimental complication.

BACKGROUND: The current standard of care for locally advanced esophageal and gastroesophageal junction (GEJ) cancers includes neoadjuvant chemoradiotherapy or perioperative chemotherapy with surgical resection; however, disease-free survival in these patients remains poor. Immune checkpoint inhibitors (ICIs) are approved for adjuvant treatment of locally advanced esophageal and GEJ cancers, but their benefit in the perioperative and neoadjuvant settings remains under investigation. METHODS: We used the PubMed online database to conduct a literature search to identify studies that investigated immunotherapy for locally advanced esophageal and GEJ carcinoma. A review of ClinicalTrials.gov yielded a list of ongoing trials. RESULTS: Adjuvant nivolumab for residual disease after neoadjuvant chemoradiotherapy and surgery is the only approved immunotherapy regimen for locally advanced esophageal cancer. Early-phase trials investigating the addition of neoadjuvant or perioperative ICIs to standard-of-care multimodality approaches have observed pathologic complete response rates as high as 60%. Response rates are highest for ICIs plus chemoradiotherapy for esophageal squamous cell carcinoma and dual checkpoint inhibition in mismatch repair-deficient adenocarcinomas. Safety profiles are acceptable, with a pooled adverse event rate of 27%. Surgical morbidity and mortality with immunotherapy are similar to historical controls with no immunotherapy, and R0 resection rates are high. When reported, disease-free survival among patients treated with perioperative immunotherapy is promising. CONCLUSIONS: Outside of clinical trials, immunotherapy for resectable esophageal carcinoma is limited to the adjuvant setting. Phase III trials investigating neoadjuvant and perioperative immunotherapy are now underway and will provide much-needed data on survival that may ultimately lead to practice-changing recommendations.

The use of octreotide in managing intrathoracic chyle leak following esophagectomy has gained popularity in the adult population. While the benefits of octreotide have been confirmed in the pediatric population, there remains limited evidence to support its use in the adults post-esophagectomy. Thus, we performed a single-institution cohort study to characterize its efficacy. The study was performed using a prospective, single-center database, from which clinicopathologic characteristics were extracted of patients who had post-esophagectomy chyle leaks. Kaplan-Meier and multivariable Cox regression analyses were performed to investigate the effect of octreotide use on chest tube duration (CTD), hospital length of stay (LOS), and overall survival (OS). In our cohort, 74 patients met inclusion criteria, among whom 27 (36.5%) received octreotide. Kaplan-Meier revealed no significant effect of octreotide on CTD (P = 0.890), LOS (P = 0.740), or OS (P = 0.570). Multivariable Cox regression analyses further corroborated that octreotide had no effect on CTD (HR = 0.62, 95% confidence interval [CI]: 0.32-1.20, P = 0.155), LOS (HR = 0.64, CI: 0.34-1.21, P = 0.168), or OS (1.08, CI: 0.53-2.19, P = 0.833). Octreotide use in adult patients with chyle leak following esophagectomy lacks evidence of association with meaningful clinical outcomes. Level 1 evidence is needed prior to further consideration in this population.

BACKGROUND: Whereas current guidelines recommend staging laparoscopy for most patients with potentially resectable gastric cancer, such a recommendation for patients with adenocarcinoma of the gastroesophageal junction (AEG) is lacking. This study sought to identify baseline clinicopathologic characteristics associated with peritoneal metastasis (PM) among patients with Siewert II AEG. METHODS: Trimodality therapy-eligible patients with Siewert II AEG (2000-2015, single institution) were retrospectively identified. A composite PM outcome was defined as follows: (1) PM at staging laparoscopy; (2) PM diagnosed during neoadjuvant chemoradiation; or (3) PM ≤6 months postoperatively. Logistic regression was used to identify features associated with PM; bootstrapped analysis (Youden J) identified the distal tumor extension that best discriminated the composite outcome. RESULTS: Of 188 patients, a composite PM outcome was observed in 26 of 188 (13.8%); 12 of 26 had positive staging laparoscopy, 10 of 26 experienced PM during chemoradiation, and 4 of 26 had PM ≤6 months postoperatively. Tumor extension below the GEJ was greater in patients with PM (median, 4.0 cm [interquartile range, 3.0-5.0] vs 3.0 cm [interquartile range, 2.0-3.0]; P < .001). All patients with PM had cT3 to cT4 tumors. Among patients with cT3 to cT4 tumors (n = 168 of 188; 89.4%), distal tumor extent (odds ratio, 1.67/cm; 95% CI, 1.23-2.28; P = .001) was independently associated with increased odds of PM. Gastric tumor extension ≥4 cm remained independently associated with PM (OR, 5.14; 95% CI, 2.11-12.53; P < .001) after adjustment for signet ring cell status. CONCLUSIONS: Distal tumor extent beyond the GEJ is independently associated with increased odds of PM in patients with Siewert II AEG. Patients with extensive gastric involvement should therefore be considered for staging laparoscopy before trimodality therapy.

BACKGROUND AND OBJECTIVES: For patients with colorectal cancer (CRC), the lung is the most common extra-abdominal site of distant metastasis. However, practices for chest imaging after colorectal resection vary widely. We aimed to identify characteristics that may indicate a need for early follow-up imaging. METHODS: We retrospectively reviewed charts of patients who underwent CRC resection, collecting clinicopathologic details and oncologic outcomes. Patients were grouped by timing of pulmonary metastases (PM) development. Analyses were performed to investigate odds ratio (OR) of PM diagnosis within 3 months of CRC resection. RESULTS: Of 1600 patients with resected CRC, 233 (14.6%) developed PM, at a median of 15.4 months following CRC resection. Univariable analyses revealed age, receipt of systemic therapy, lymph node ratio (LNR), lymphovascular and perineural invasion, and KRAS mutation as risk factors for PM. Furthermore, multivariable regression showed neoadjuvant therapy (OR: 2.99, p < 0.001), adjuvant therapy (OR: 6.28, p < 0.001), LNR (OR: 28.91, p < 0.001), and KRAS alteration (OR: 5.19, p < 0.001) to predict PM within 3 months post-resection. CONCLUSIONS: We identified clinicopathologic characteristics that predict development of PM within 3 months after primary CRC resection. Early surveillance in such patients should be emphasized to ensure timely identification and treatment of PM.

OBJECTIVE: Chemotherapy plus nivolumab is the standard of care neoadjuvant treatment for patients with resectable stage IB to IIIA non-small cell lung cancer. The influence of dual checkpoint blockade with chemotherapy on surgical outcomes remains unknown. We aimed to determine operative complexity and perioperative outcomes associated with neoadjuvant chemotherapy and nivolumab with or without ipilimumab. METHODS: A total of 44 patients with stage IB (≥4 cm) to IIIA non-small cell lung cancer were treated on sequential platform arms of the NEOSTAR trial. A total of 22 patients were treated with nivolumab + chemotherapy, and 22 patients were treated with ipilimumab + nivolumab + chemotherapy. The safety of surgical resection after neoadjuvant therapy was estimated using 30-day complication rates. Operative reports and surgeons' narratives were evaluated to determine procedural complexity and operative conduct. RESULTS: All 22 of 22 patients (100%) treated with nivolumab + chemotherapy underwent surgical resection: 20 R0 (90.9%), 17 (77.3%) lobectomies, 1 wedge resection, 2 segmentectomies, and 2 pneumonectomies. The majority, 21 of 22 (95%), were performed by thoracotomy. A total of 13 of 22 (59.1%) were rated as challenging resections. A total of 4 of 22 patients (18.2%) experienced grade 3 or greater Clavien-Dindo complication. A total of 20 of 22 patients (90.9%) treated with ipilimumab + nivolumab + chemotherapy underwent surgical resection: 19 R0 (95%), 18 (90%) lobectomies, 1 pneumonectomy, and 1 segmentectomy. A total of 16 of 20 (80%) resections were performed via thoracotomy, 3 of 20 (15%) via robotics, and 1 of 20 (5%) via thoracoscopy. A total of 9 of 20 (45%) resections were considered challenging. A total of 4 of 20 patients (20%) experienced grade 3 or greater Clavien-Dindo complication. CONCLUSIONS: Surgical resections are feasible and safe, with high rates of R0 after neoadjuvant chemotherapy and nivolumab with or without ipilimumab. Overall, approximately half of cases (22/42, 52.3%) were considered to be more challenging than a standard lobectomy.

Outcomes for patients with esophageal cancer have improved over the last decade with the implementation of multimodality therapy. There are currently no comprehensive guidelines addressing multidisciplinary management of esophageal cancer that have incorporated the input of surgeons, radiation oncologists, and medical oncologists. To address the need for multidisciplinary input in the management of esophageal cancer and to meet current best practices for clinical practice guidelines, the current guidelines were created as a collaboration between The Society of Thoracic Surgeons (STS), American Society for Radiation Oncology (ASTRO), and the American Society of Clinical Oncology (ASCO). Physician representatives chose 8 key clinical questions pertinent to the care of patients with locally advanced, resectable thoracic esophageal cancer (excluding cervical location). A comprehensive literature review was performed identifying 227 articles that met the inclusion criteria covering the use of induction chemotherapy, chemotherapy vs chemoradiotherapy before surgery, optimal radiation dose, the value of esophagectomy, timing of esophagectomy, the approach and extent of lymphadenectomy, the use of minimally invasive esophagectomy, and the value of adjuvant therapy after resection. The relevant data were reviewed and voted on by the panel with 80% of the authors, with 75% agreement on class and level of evidence. These data were then complied into the guidelines document.

OBJECTIVE: We have previously demonstrated the negative impact of travel distance on adherence to surveillance imaging guidelines for resected non-small cell lung cancer (NSCLC). The influence of patient residential location on adherence to recommended postoperative treatment plans remains unclear. We sought to characterize the impact of travel distance on receipt of indicated adjuvant therapy in resected NSCLC. METHODS: We performed a single-institution, retrospective review of patients with stage II-III NSCLC who underwent upfront pulmonary resection, 2012-2016. Clinicopathologic and operative/perioperative details of treatment were collected. Travel distance was measured from patients' homes to the operative hospital. Our primary outcome was receipt of adjuvant systemic or radiotherapy. Travel distance was stratified as <100 or >100 miles. Multivariable logistic regression was performed. RESULTS: In total, 391 patients met inclusion criteria, with mean age of 65.9 years and fairly even sex distribution (182 women, 49.2%). Most patients were Non-Hispanic White (n = 309, 83.5%), and most frequent clinical stage was II (n = 254, 64.9%). Indicated adjuvant therapy was received by 266 (71.9%), and median distance traveled was 209 miles (interquartile range, 50.7-617). Multivariate analysis revealed that longer travel distance was inversely associated with receipt of indicated adjuvant therapy (odds ratio, 0.13; 95% confidence interval, 0.06-0.26; P < .001). In addition, Black patients were less likely to receive appropriate treatment (odds ratio, 0.05; 95% confidence interval, 0.02-0.15; P < .001). CONCLUSIONS: Travel distance >100 miles negatively impacts the likelihood of receiving indicated adjuvant therapy in NSCLC. Indications for systemic therapy in earlier staged disease are rapidly expanding, and these findings bear heightened relevance as we aim to provide equitable access to all patients.

BACKGROUND: Appropriately selected patients clearly benefit from resection of colorectal cancer (CRC) pulmonary metastases (PMs). However, there remains equipoise surrounding optimal chest surveillance strategies following pulmonary metastasectomy. We aimed to identify risk factors that may inform chest surveillance in this population. METHODS: Patients who underwent CRC pulmonary metastasectomy were identified from a single institution's prospectively maintained surgical database. Clinicopathologic and genomic characteristics were collected. Patients were stratified by diagnosis of subsequent PM within 6 months of the index lung resection. Multivariate modeling was used to evaluate risk factors. RESULTS: A total of 197 patients met the study's inclusion criteria, of whom 52.3% (n = 103) developed subsequent PM, at a median of 9.51 months following the index metastasectomy. Patients with KRAS alterations (odds ratio [OR], 3.073; 95% confidence interval [CI], 1.363-6.926; P = .007), TP53 alterations (OR, 3.109; 95% CI, 1.318-7.341; P = .010) were found to be at risk of PM diagnosis within 6 months of the index metastasectomy, while those with an APC alteration (OR, .218; 95% CI, 0.080-0.598; P = .003) were protected. Moreover, patients who received systemic therapy within 3 months of the initial PM diagnosis also were more likely to develop early lung recurrence (OR, 2.105; 95% CI, 0.971-4.563; P = .059). CONCLUSIONS: Patients with KRAS alterations, TP53 alterations, and no APC alterations developed early recurrence in the lung following pulmonary metastasectomy, as did those who received chemotherapy after their initial PM diagnosis. As such, these groups benefit from early lung imaging after metastasectomy, as chest surveillance protocols should be based on patient-centered clinicopathologic and genomic risk factors.

OBJECTIVE: We evaluated self-reported financial burden (FB) after lung cancer surgery and sought to assess patient perspectives, risk factors, and coping mechanisms within this population. METHODS: Patients with lung cancer resected at our institution between January 1, 2016, and December 31, 2021, were surveyed. Descriptive and multivariable analyses were performed to evaluate the association between clinical and financial characteristics with patient-reported major ("significant" or "catastrophic") FB. RESULTS: Of 1477 patients contacted, 31.3% (n = 463) completed the survey. Major FB was reported by 62 (13.4%) patients. multivariable analyses demonstrated increasing age (odds ratio [OR], 0.92; 95% CI, 0.88-0.96), credit score >740 (OR, 0.29; 95% CI, 0.14-0.60), and employer-based insurance (OR, 0.24; 95% CI, 0.07-0.80) were protective factors. In contrast, an out of pocket cost greater than expected (OR, 3.63; 95% CI, 1.67-7.88), decrease in work hours (OR, 4.42; 95% CI, 1.59-12.25), or cessation of work (OR, 5.13; 95% CI, 2.06-12.78), chronic obstructive pulmonary disease diagnosis (OR, 5.39, 95% CI, 1.87-15.50), and hospital readmission (OR, 4.87; 95% CI, 1.11-21.42) were risk factors for FB. To pay for care, some patients reported "often" or "always" decreasing food (n = 102 [23.4%]) or leisure spending (n = 179 [40.7%]). Additionally, use of savings (n = 246 [62.9%]), borrowing funds (n = 72 [16.6%]), and skipping clinic visits (n = 36 [8.3%]) at least once were also reported. Coping mechanisms occurred more often in patients with major FB compared with those without (P < .001). CONCLUSIONS: Patients with resected lung cancer may experience major FB related to treatment with several identifiable risk factors. Targeted interventions are needed to limit the adoption of detrimental coping mechanisms and potentially affect survivorship.

OBJECTIVES: Disparities in cancer care are omnipresent and originate from a multilevel set of barriers. Our objectives were to describe the likelihood of undergoing surgery for early-stage non-small cell lung cancer at minority-serving hospitals (MSHs), and evaluate the association of race/ethnicity with resection based on MSH status. METHODS: A retrospective study using the National Cancer Database (2008-2016) was conducted including patients with clinical stage I non-small cell lung cancer. MSHs were defined as hospitals in the top decile of providing care to Hispanic or African American patients. The primary outcome evaluated was receipt of definitive surgery at MSHs vs non-MSHs. Outcomes related to race/ethnicity stratified by hospital type were also investigated. RESULTS: A total of 142,580 patients were identified from 1192 hospitals (120 MSHs and 1072 non-MSHs). Most patients (85% [n = 121,240]) were non-Hispanic White, followed by African American (9% [n = 12,772]), and Hispanic (3%, [n= 3749]). MSHs cared for 7.4% (n = 10,491) of the patients included. In adjusted analyses, patients treated at MSHs were resected less often than those at non-MSHs (odds ratio, 0.87; 95% CI, 0.76-1.00; P = .0495). African American patients were less likely to receive surgery in the overall analysis (P < .01), and at MSHs specifically (P < .01), compared with non-Hispanic White patients. Hispanic patients had similar rates of resection in the overall analysis (P = .11); however, at MSHs, they underwent surgery more often compared with non-Hispanic White patients (P = .02). Resected patients at MSHs had similar overall survival (median, 91.7 months; 95% CI, 86.6-96.8 months) compared with those resected at non-MSHs (median, 85.7 months; 95% CI, 84.5-86.8 months). CONCLUSIONS: Patients with early-stage non-small cell lung cancer underwent resection less often at MSHs compared with non-MSHs. Disparities related to underutilization of surgery for African American patients continue to persist, regardless of hospital type.
