Association of Medicaid expansion with 2-year survival and time to treatment initiation in gastrointestinal cancer patients: A National Cancer Database study. J Surg Oncol 2023; 128:1285-1301. [PMID: 37781956 DOI: 10.1002/jso.27456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 09/10/2023] [Accepted: 09/17/2023] [Indexed: 10/03/2023]
Abstract
INTRODUCTION We evaluated whether Medicaid expansion (ME) was associated with improved 2-year survival and time to treatment initiation (TTI) among patients with gastrointestinal (GI) cancer. METHODS GI cancer patients diagnosed 40-64 years were queried from the National Cancer Database. Those diagnosed from 2010 to 2012 were considered pre-expansion; those diagnosed from 2014 to 2016 were considered post-expansion. Cox models estimated hazard ratios and 95% confidence intervals (CIs) for 2-year overall survival. Generalized estimating equations (GEE) estimated odds ratios (OR) and 95% CI of TTI within 30- and 90 days. Multivariable Difference-in-Difference models were used to compare expansion/nonexpansion cohorts pre-/post-expansion, adjusting for patient, clinical, and hospital factors. RESULTS 377,063 patients were included. No significant difference in 2-year survival was demonstrated across ME and non-ME states overall or in site-based subgroup analysis. In stage-based subgroup analysis, 2-year survival significantly improved among stage II cancer, with an 8% decreased hazard of death at 2 years (0.92; 0.87-0.97). Those with stage IV had a 4% increased hazard of death at 2 years (1.04; 1.01-1.07). Multivariable GEE models showed increased TTI within 30 days (1.12; 1.09-1.16) and 90 days (1.22; 1.17-1.27). Site-based subgroup analyses indicated increased likelihood of TTI within 30 and 90 days among colon, liver, pancreas, rectum, and stomach cancers, by 30 days for small intestinal cancer, and by 90 days for esophageal cancer. In subgroup analyses, all stages experienced improved odds of TTI within 30 and 90 days. CONCLUSION ME was not associated with significant improvement in 2-year survival for those with GI cancer. Although TTI increased after ME for both cohorts, the 30- and 90-day odds of TTI was higher for those from ME compared with non-ME states. Our findings add to growing evidence of associations with ME for those diagnosed with GI cancer.

Abstract
ABSTRACT We report a case of ulcerative fungal esophagitis with elevated activity of 18 F-FDG and 68 Ga-FAPI (fibroblast-activating protein inhibitor). Our findings suggest that ulcerative fungal esophagitis should be considered in the differential diagnosis of cancer-like esophageal mass with increased 68 Ga-FAPI uptake.

Abstract
MAGEA family proteins are immunogenic and can produce corresponding autoantibodies, and we aim to evaluate the diagnostic value of anti-MAGEA family protein autoantibodies in esophageal squamous cell carcinoma (ESCC). Protein chip was used to detect the expression level of anti-MAGEA autoantibodies (IgG and IgM) in 20 mixed serum samples. Enzyme linked immunosorbent assay was adopted to determine the expression level of autoantibodies in 1019 serum samples (423 ESCC, 423 healthy control (HC), 173 benign esophageal disease (BED)), and stepwise logistic regression analysis was used for developing a diagnostic model. Eight anti-MAGEA autoantibodies were screened out based on the protein chip. The levels of 7 autoantibodies (MAGEA1-IgG, MAGEA3-IgG, MAGEA3-IgM, MAGEA4-IgG, MAGEA6-IgG, MAGEA10-IgG, MAGEA12-IgG) in ESCC were significantly higher than that in HC, and the levels of anti-MAGEA1 IgG, anti-MAGEA3-IgG, anti-MAGEA4-IgG, anti-MAGEA10-IgG and anti-MAGEA12-IgG autoantibodies in ESCC group were significantly higher than those in BED group. The area under curve (AUC), sensitivity and specificity of the logistic regression model (MAGEA1-IgG, MAGEA4-IgG, MAGEA6-IgG, MAGEA12-IgG) in the training set and the validation set were 0.725 and 0.698, 55.2% and 51.8%, 80.4% and 84.5%, respectively, in distinguishing ESCC and HC. The model also could distinguish between ESCC and BED, with the AUC of 0.743, sensitivity of 55.4% and specificity of 89.0%. The positive rate of the model combined with cytokeratin 19 fragment to diagnose ESCC reached 78.0%. The study identified anti-MAGEA autoantibodies with potential diagnostic value for ESCC, which may provide new promising for the detection of the disease.

Abstract
BACKGROUND We investigated the associations between postoperative delirium (POD) and both the relative ratio of the alpha (α)-power of electroencephalography (EEG) and inflammatory markers in a prospective, single-center observational study. METHODS We enrolled 84 patients who underwent radical cancer surgeries with reconstruction for esophageal cancer, oral floor cancer, or pharyngeal cancer under total intravenous anesthesia. We collected the perioperative EEG data and the perioperative data of the inflammatory markers, including neutrophil gelatinase-associated lipocalin, presepsin, procalcitonin, C-reactive protein, and the neutrophil-lymphocyte ratio (NLR). The existence of POD was evaluated based on the Intensive Care Delirium Screening Checklist. We compared the time-dependent changes in the relative ratio of the EEG α-power and inflammatory markers between the patients with and without POD. RESULTS Four of the 84 patients were excluded from the analysis. Of the remaining 80 patients, 25 developed POD and the other 55 did not. The relative ratio of the α-power at baseline was significantly lower in the POD group than the non-POD group (0.18 ± 0.08 vs 0.28 ± 0.11, P < .001). A time-dependent decline in the relative ratio of α-power in the EEG during surgery was observed in both groups. There were significant differences between the POD and non-POD groups in the baseline, 3-h, 6-h, and 9-h values of the relative ratio of α-power. The preoperative NLR of the POD group was significantly higher than that of the non-POD group (2.88 ± 1.04 vs 2.22 ± 1.00, P < .001), but other intraoperative inflammatory markers were comparable between the groups. Two multivariable logistic regression models demonstrated that the relative ratio of the α-power at baseline was significantly associated with POD. CONCLUSIONS Intraoperative frontal relative ratios of the α-power of EEG were associated with POD in patients who underwent radical cancer surgery. Intraoperative EEG monitoring could be a simple and more useful tool for predicting the development of postoperative delirium than measuring perioperative acute inflammatory markers. A lower relative ratio of α-power might be an effective marker for vulnerability of brain and ultimately for the development of POD.

Abstract
BACKGROUND Dynamic alterations of the tumor immune microenvironment in esophageal squamous cell carcinoma (ESCC) after different neoadjuvant therapies were understudied. METHODS We used mass cytometry with a 42-antibody panel for 6 adjacent normal esophageal mucosa and 26 tumor samples (treatment-naïve, n=12; postneoadjuvant, n=14) from patients with ESCC. Single-cell RNA sequencing of previous studies and bulk RNA sequencing from The Cancer Genome Atlas were analyzed, flow cytometry, immunohistochemistry, and immunofluorescence analyses were performed. RESULTS Poor tumor regression was observed in the neoadjuvant chemotherapy group. Radiotherapy-based regimens enhanced CD8+ T cells but diminished regulatory T cells and promoted the ratio of effector memory to central memory T cells. Immune checkpoint blockade augmented NK cell activation and cytotoxicity by increasing the frequency of CD16+ NK cells. We discovered a novel CCR4+CCR6+ macrophage subset that correlated with the enrichment of corresponding chemokines (CCL3/CCL5/CCL17/CCL20/CCL22). We established a CCR4/CCR6 chemokine-based model that stratified ESCC patients with differential overall survival and responsiveness to neoadjuvant chemoradiotherapy combined with immunotherapy, which was validated in two independent cohorts of esophageal cancer with neoadjuvant treatment. CONCLUSIONS This work reveals that neoadjuvant therapy significantly regulates the cellular composition of the tumor immune microenvironment in ESCC and proposes a potential model of CCR4/CCR6 system to predict the benefits from neoadjuvant chemoradiotherapy combined with immunotherapy.

Abstract
In the last decade, the use of immunomodulating treatments (IMT) at integrative oncology providers (IOP) increased. IMTs are used to modulate the tumor microenvironment, which might lead to increased response-to-treatment, and the indication of immune checkpoint inhibitors might also be widened. The efficacy and safety of IMTs in advanced/metastatic gastrointestinal cancers were compared with conventional chemo(radio)therapy (CT). 21 colorectal- (CRC), 14 pancreatic- (PC), 5 cholangiocellular- (CCC), 5 gastric- (GC) and 4 esophageal cancer (EC) patients received IMT. IMT and CT were compared in CRC and PC. CT was administered at an academic oncology center. After the initiation of IMT, a median survival of ~ 20 (CRC, PC and EC) and ~ 10 months (CCC and GC) was observed. Of the IMTs, locoregional modulated electro-hyperthermia had the most positive effect on overall survival (HR: 0.3055; P = 0.0260), while fever-inducing interleukin-2, and low-dose ipilimumab showed a positive tendency. IMT was superior to CT in PC (HR: 0.1974; P = 0.0013), while modest effect was detected in CRC (HR: 0.7797; P = 0.4710). When the whole study population was analyzed, IMTs showed minimal effect on patient survival, still CT had the greatest effect if introduced as early as possible (HR: 0.0624; P < 0.0001). The integrative IMTs in the presented form have mild impact on gastrointestinal cancer patients' survival, however, we observed its benefit in PC, which warrants further investigations.

Abstract
Homeodomain (HD)-containing proteins are typically recognized as transcription factors. Engrailed 2 (EN2) is an HD-containing protein that is highly expressed in various types of cancers, however, the mechanism underlying the biological function of EN2 is not fully understood. Here, we report a transcription-independent function of EN2 in addition to its role as a transcription factor. EN2 expression leads to the activation of multiple signaling pathways mediated by phosphorylation cascades. A phosphoproteomic analysis revealed that the phosphorylation status of numerous protein sites was altered after EN2 is expressed. Notably, EN2 was shown to interact with a myriad of proteins implicated in phosphorylation signaling cascades, as determined by immunoprecipitation-mass spectrometry (IP-MS). We validated the interaction between EN2 and B55α, the regulatory subunit of the PP2A-B55α complex, and confirmed that the phosphatase activity of the complex was suppressed by EN2 binding. To target EN2-induced malignancy, two kinds of small molecules were utilized to inhibit the EN2-activated NF-κB and AKT signaling pathways. A clear synergistic effect was observed when the activation of the two pathways was simultaneously blocked. Collectively, the data show that EN2 functions in a transcription-independent manner in addition to its role as a transcription factor. This finding may have therapeutic implications in treating esophageal squamous cell carcinoma (ESCC).

Abstract
Chinese doctors are required to inform patients' direct relatives of a cancer diagnosis rather than the patients themselves. The disease may be hidden from patients by their family members, which could result in severe outcomes. We selected postoperative T3 esophageal cancer (EsC) patients hospitalized from June 2015 to December 2019 as research subjects. The patients were divided into a direct-notification group and an indirect-notification group. Several variables were used to evaluate both groups' 36-month progress-free survival (PFS). A risk prediction model of prognosis based on the risk score was established, which was assessed using the area under the curve (AUC) of the receiver operating characteristic curve. One hundred and thirteen patients were enrolled in the training group and forty-eight in the validation group. Cox multivariate regression analysis revealed that males, late stage, poor pathological differentiation, and indirect notification were independent worse risk factors for postoperative T3 stage EsC patients at 36-month PFS (hazard ratio (HR) = 0.454, 95% confidence interval (CI): 0.254-0.812, P = .008; HR = 1.560, 95% CI: 1.006-2.420, P = .047; HR = 0.595, 95% CI: 0.378-0.936, P = .025; HR = 2.686, 95% CI: 1.679-4.297, P < 0.001, respectively). The type of notification was the best correlation factor. The risk score was calculated as follows: risk score = 0.988 × cancer notification (indirect = 1, direct = 0)-0.790 × sex (female = 1, Male = 0) + 0.445 × stage (IIIB = 1, IIA + IIB = 0)-0.519 × pathological differentiation (moderately + well = 1, poorly = 0). The model had a sensitivity of 64.8% and specificity of 81.8%, with the AUC at 0.717 (95% CI: 0.614-0.810) in internal verification, and a sensitivity of 56.8% and specificity of 100%, with the AUC at 0.705 (95% CI: 0.651-0.849) in external validation. The model had good internal and external stability. The model showed a Brier score of 0.18. Indirect notification of a cancer diagnosis was an important negative predictor of postoperative EsC patients' PFS. The model displayed good accuracy and stability in the prediction of risk for cancer progression.

Abstract
BACKGROUND Residual tumor at the proximal or distal margin after esophagectomy is associated with worse survival outcomes; however, the significance of the circumferential resection margin (CRM) remains controversial. In this study, we sought to evaluate the prognostic significance of the CRM in patients with esophageal cancer undergoing resection. MATERIALS AND METHODS We identified patients who underwent esophagectomy for pathologic T3 esophageal cancer from 2000 to 2019. Patients were divided into three groups: CRM- (residual tumor >1 mm from the CRM), CRM-close (residual tumor >0 to 1 mm from the CRM), and CRM+ (residual tumor at the surgical CRM). CRM was also categorized and analyzed per the Royal College of Pathologists (RCP) and College of American Pathologists (CAP) classifications. RESULTS Of the 519 patients included, 351 (68%) had CRM-, 132 (25%) had CRM-close, and 36 (7%) had CRM+. CRM+ was associated with shorter disease-free survival [DFS; CRM+ vs. CRM-: hazard ratio (HR), 1.53 [95% CI, 1.03-2.28]; P =0.034] and overall survival (OS; CRM+ vs. CRM-: HR, 1.97 [95% CI, 1.32-2.95]; P <0.001). Survival was not significantly different between CRM-close and CRM-. After adjustment for potential confounders, CAP+ was associated with poor oncologic outcomes (CAP+ vs. CAP-: DFS: HR, 1.47 [95% CI, 1.00-2.17]; P =0.050; OS: HR, 1.93 [95% CI, 1.30-2.86]; P =0.001); RCP+ was not (RCP+ vs. RCP-: DFS: HR, 1.21 [95% CI, 0.97-1.52]; P =0.10; OS: HR, 1.21 [95% CI, 0.96-1.54]; P =0.11). CONCLUSION CRM status has critical prognostic significance for patients undergoing esophagectomy: CRM+ was associated with worse outcomes, and outcomes between CRM-close and CRM- were similar.

Abstract
OBJECTIVE To determine the impact of delayed surgical intervention following chemoradiotherapy (CRT) on survival from esophageal cancer. BACKGROUND CRT is a core component of multimodality treatment for locally advanced esophageal cancer. The timing of surgery following CRT may influence the probability of performing an oncological resection and the associated operative morbidity. METHODS This was an international, multicenter, cohort study, including patients from 17 centers who received CRT followed by surgery between 2010 and 2020. In the main analysis, patients were divided into 4 groups based upon the interval between CRT and surgery (0-50, 51-100, 101-200, and >200 days) to assess the impact upon 90-day mortality and 5-year overall survival. Multivariable logistic and Cox regression provided hazard ratios (HRs) with 95% CIs adjusted for relevant patient, oncological, and pathologic confounding factors. RESULTS A total of 2867 patients who underwent esophagectomy after CRT were included. After adjustment for relevant confounders, prolonged interval following CRT was associated with an increased 90-day mortality compared with 0 to 50 days (reference): 51 to 100 days (HR=1.54, 95% CI: 1.04-2.29), 101 to 200 days (HR=2.14, 95% CI: 1.37-3.35), and >200 days (HR=3.06, 95% CI: 1.64-5.69). Similarly, a poorer 5-year overall survival was also observed with prolonged interval following CRT compared with 0 to 50 days (reference): 101 to 200 days (HR=1.41, 95% CI: 1.17-1.70), and >200 days (HR=1.64, 95% CI: 1.24-2.17). CONCLUSIONS Prolonged interval following CRT before esophagectomy is associated with increased 90-day mortality and poorer long-term survival. Further investigation is needed to understand the mechanism that underpins these adverse outcomes observed with a prolonged interval to surgery.

Abstract
OBJECTIVE We previously reported that dickkopf WNT signaling inhibitor 3 (DKK3) would modulate malignant potential of oral squamous cell carcinoma (OSCC) via activating Akt. Recently, cytoskeleton associated protein 4 (CKAP4) functions as receptor of DKK3, which activates Akt in esophageal squamous cell carcinoma, but its expression and function in OSCC were unclear. METHODS We studied DKK3 and CKAP4 protein expression in OSCC tissue and investigated the correlation between protein expression and clinical data. We also investigated whether antibodies (Ab) for DKK3 or CKAP4 could suppress malignant potential of the cancer cells. RESULTS DKK3/CKAP4 protein expression was observed in majority of OSCC cases and was associated with significantly higher T-stage and TNM stage. Multivariate analysis revealed that DKK3 and CKAP4 were independent prognostic biomarkers for overall survival (OS) and disease-free survival (DFS), respectively. Survival analyses revealed that DKK3-positive cases and CKAP4-positive cases showed significantly shorter OS and DFS, respectively, and that DKK3/CKAP4 double-negative cases showed significantly favorable prognosis. Both anti-DKK3Ab and anti-CKAP4Ab could suppress cancer cell proliferation, migration, and invasion. CONCLUSION DKK3/CKAP4 axis is thought to be important in OSCC, and it would be a promising therapeutic target.

Abstract
BACKGROUND Neoadjuvant therapy in combination with surgery increases survival in gastroesophageal cancer; however, little is known about its impact on health-related quality of life. This study compared the impact of neoadjuvant therapy with that of surgery alone on the health-related quality of life in patients treated for gastroesophageal cancer. METHODS A single-centre cohort study with prospectively collected data from patients undergoing curative intended treatment for gastroesophageal cancer between 2013 and 2020 was performed. Health-related quality of life was assessed prior to surgery and patients stratified according to neoadjuvant therapy or surgery alone. The primary endpoint was self-assessed health-related quality of life, evaluated using validated cancer-specific questionnaires. A pre-specified multivariable model adjusted for age, ASA score, and clinical T- and N-stage was used. RESULTS A total of 361 patients were included, of whom 239 (61%) were treated with neoadjuvant therapy. Patients treated with neoadjuvant therapy reported less difficulties with eating restrictions (-11.9, p = 0.005), pain (-10.9, p = 0.004), and insomnia (-12.6, p = 0.004) than patients treated with surgery alone. Patients with oesophageal cancer and neoadjuvant therapy reported less dysphagia (-16.6, p < 0.001), eating restrictions (-23.2, p < 0.001), and odynophagia (-18.0, p = 0.002) than those who underwent surgery alone. CONCLUSION Neoadjuvant therapy was associated with a significant reduction in symptoms affecting malnutrition and improved health-related quality of life in patients with gastroesophageal cancer. These results indicates that more patients might be available for neoadjuvant therapy, despite the baseline burden of gastroesophageal cancer.

Abstract
The programmed cell death 1 protein (PD-1)/programmed cell death ligand 1 (PD-L1) axis plays a crucial role in tumor immunosuppression, while the cancer-associated fibroblasts (CAFs) have various tumor-promoting functions. To determine the advantage of immunotherapy, the relationship between the cancer cells and the CAFs was evaluated in terms of the PD-1/PD-L1 axis. Overall, 140 cases of esophageal cancer underwent an immunohistochemical analysis of the PD-L1 expression and its association with the expression of the α smooth muscle actin, fibroblast activation protein, CD8, and forkhead box P3 (FoxP3) positive cells. The relationship between the cancer cells and the CAFs was evaluated in vitro, and the effect of the anti-PD-L1 antibody was evaluated using a syngeneic mouse model. A survival analysis showed that the PD-L1+ CAF group had worse survival than the PD-L1- group. In vitro and in vivo, direct interaction between the cancer cells and the CAFs showed a mutually upregulated PD-L1 expression. In vivo, the anti-PD-L1 antibody increased the number of dead CAFs and cancer cells, resulting in increased CD8+ T cells and decreased FoxP3+ regulatory T cells. We demonstrated that the PD-L1-expressing CAFs lead to poor outcomes in patients with esophageal cancer. The cancer cells and the CAFs mutually enhanced the PD-L1 expression and induced tumor immunosuppression. Therefore, the PD-L1-expressing CAFs may be good targets for cancer therapy, inhibiting tumor progression and improving host tumor immunity.

Usefulness of Biopsy Specimens for Evaluating CD103 + Tumor-resident Memory T Cells in Esophageal Cancer. Anticancer Res 2023; 43:4823-4832. [PMID: 37909993 DOI: 10.21873/anticanres.16679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/07/2023] [Accepted: 09/11/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND/AIM CD103+ tissue-resident memory T cells (TRM) in tumor sites are associated with a favorable prognosis and predict the effectiveness of immune checkpoint inhibitors. The detection of CD103+ TRM infiltration in biopsy samples could be beneficial for patients without surgical indications. However, the usefulness of TRM detection in biopsy tissue and the difference in TRM status between biopsy and surgical specimens' post-neoadjuvant chemotherapy have not been elucidated. In the present study, we aimed to elucidate whether we can detect TRM in biopsy specimens and the impact of chemotherapy on TRM infiltration. MATERIALS AND METHODS Tissue sections were obtained from 46 patients with esophageal cancer who received neoadjuvant chemotherapy and underwent radical esophagectomy in 2017. Immunohistochemistry was performed using an anti-CD103 antibody for biopsy and surgical specimens. We examined the relationship between CD103 expression, clinicopathological features, and prognosis for each patient. RESULTS TRM infiltration was detected in the biopsy specimens. CD103 expression in biopsy specimens correlated with that in surgical specimens. Although there was no statistical significance in clinicopathological findings between CD103high and CD103low, patients with CD103high biopsy specimens exhibited favorable prognosis. The number of CD103+ cells was increased by chemotherapy: though with no survival benefit. CONCLUSION Regardless of surgical indication, we were able to determine the TRM status even in biopsy specimens. CD103 evaluation at biopsy may be more useful and practical than evaluation in surgical specimens, enabling prediction of prognosis and response to immune therapy.

Abstract
RNA N6-methyladenosine (m6A) modification is implicated in cancer progression, yet its role in regulating long noncoding RNAs during cancer progression remains unclear. Here, we report that the m6A demethylase fat mass and obesity-associated protein (FTO) stabilizes long intergenic noncoding RNA for kinase activation (LINK-A) to promote cell proliferation and chemoresistance in esophageal squamous cell carcinoma (ESCC). Mechanistically, LINK-A promotes the interaction between minichromosome maintenance complex component 3 (MCM3) and cyclin-dependent kinase 1 (CDK1), increasing MCM3 phosphorylation. This phosphorylation facilitates the loading of the MCM complex onto chromatin, which promotes cell-cycle progression and subsequent cell proliferation. Moreover, LINK-A disrupts the interaction between MCM3 and hypoxia-inducible factor 1α (HIF-1α), abrogating MCM3-mediated HIF-1α transcriptional repression and promoting glycolysis and chemoresistance. These results elucidate the mechanism by which FTO-stabilized LINK-A plays oncogenic roles and identify the FTO/LINK-A/MCM3/HIF-1α axis as a promising therapeutic target for ESCC.

Cancer and Atrial Fibrillation Comorbidities Among 25 Million Citizens in Shanghai, China: Medical Insurance Database Study. JMIR Public Health Surveill 2023; 9:e40149. [PMID: 37847541 PMCID: PMC10618890 DOI: 10.2196/40149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 11/13/2022] [Accepted: 09/19/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND With population aging, the prevalence of both cancer and atrial fibrillation (AF) have increased. However, there is scarce epidemiological data concerning the comorbid state of cancer and AF in low- and middle-income countries, including China. OBJECTIVE We aimed to evaluate the site-, sex-, and age-specific profiles of cancer and AF comorbidities in Chinese populations. METHODS Data from the Shanghai Municipal Health Commission database between 2015 and 2020 were screened, covering all medical records of Shanghai residents with medical insurance. Site-specific cancer profiles were evaluated for the population with AF relative to the age- and sex-adjusted population of residents without AF. The sex distribution and peak age of cancer diagnosis were also assessed. RESULTS A total of 25,964,447 adult patients were screened. Among them, 22,185 patients presented cancers comorbid with AF (median 77, IQR 67-82 years of age; men: n=13,631, 61.44%), while 839,864 presented cancers without AF (median 67, IQR 57-72 years of age; men: n=419,020, 49.89%), thus yielding a higher cancer prevalence among residents with AF (8.27%) than among those without AF (6.05%; P<.001). In the population with AF, the most prevalent cancer type was lung cancer, followed by colorectal, male genital organ, stomach, breast, liver, bladder, thyroid, leukemia, and esophageal cancers. AF was associated with an average of nearly 1.4-fold (prevalence ratio [PR] 1.37, 95% CI 1.35-1.38) increased prevalence of cancer after adjusting for age and sex. For site-specific analyses, an increased prevalence of cancer in the population with AF was observed in 20 of 21 cancer sites. This increased prevalence was most prominent for nonsolid tumors, including multiple myeloma (PR 2.56, 95% CI 2.28-2.87), leukemia (PR 1.73, 95% CI 1.57-1.90), and non-Hodgkin lymphoma (PR 1.59, 95% CI 1.43-1.77); intrathoracic malignancies, including mediastinum (PR 2.34, 95% CI 1.89-2.90), lung (PR 1.64, 95% CI 1.59-1.69), and esophageal cancers (PR 1.41, 95% CI 1.28-1.56); bone and soft tissue neoplasms (PR 1.56, 95% CI 1.37-1.77); and kidney cancer (PR 1.53, 95% CI 1.36-1.72). Cancer prevalence in the population with AF relative to that in the population without AF was higher in men than in women in 14 of 18 cancer sites, and female predominance was only observed for thyroid cancer. The peak age of index cancer diagnosis was lower in the population with AF (age group: 70-74 years) than in that without AF (age group: 75-79 years), especially for specific cancer types, including thyroid, central nervous system, mediastinum, esophageal, bladder, and biliary cancers. CONCLUSIONS Patients with AF are associated with increased prevalence, heightened male predominance, and younger peak age of cancer. Further studies are needed to determine whether early screening of specific cancers is cost-effective and beneficial for patients with AF.

Support Care Cancer 2023; 31:633. [PMID: 37843658 PMCID: PMC10579144 DOI: 10.1007/s00520-023-08100-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 10/02/2023] [Indexed: 10/17/2023]
Abstract
PURPOSE Nutritional management of patients with esophageal cancer is a significant issue. This systematic review aimed to comprehensively synthesize qualitative research evidence on the experiences and requirements in nutritional management from the perspective of patients with esophageal cancer. METHODS A systematic review and meta-synthesis of qualitative studies were conducted. Studies written in Chinese or English were retrieved from nine databases, namely, PubMed, Web of Science, Cochrane Library, CINAHL, Embase, CNKI, WanFang, VIP, and SinoMed, from inception to December 23, 2022. After screening the titles, abstracts, and full texts, 19 articles were finally included for quality assessment and meta-synthesis. RESULTS Three comprehensive themes were derived. These were dietary experiences (perception of symptoms and dietary behaviors), emotional experiences (negative and positive emotions), and social support (inappropriate social support and inadequate nutritional management). CONCLUSIONS The experiences and requirements of esophageal cancer patients in terms of nutritional management during treatment and rehabilitation were reviewed and factors influencing nutritional management were discussed. The findings suggested that medical institutions should expedite the development of comprehensive nutritional management systems, create conducive nutritional environmental facilities, and establish interdisciplinary teams to implement personalized comprehensive interventional models for the management of patient nutrition. These steps would maximize the effectiveness of nutritional therapy, promote early patient recovery, and bridge the gap between healthcare professionals and patients in the understanding of nutritional management.

Cancer Epidemiol Biomarkers Prev 2023; 32:1284-1293. [PMID: 37505927 PMCID: PMC10543962 DOI: 10.1158/1055-9965.epi-23-0532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 06/26/2023] [Accepted: 07/26/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND Geographic variability in esophageal cancer has been reported in China, but data are lacking at the local level. We aimed to investigate changes in disparities in esophageal cancer-related mortality among Chinese counties and whether county-level socioeconomic status was associated with this variation. METHODS We used data from a nationwide survey and population-based cancer registries to calculate esophageal cancer-related mortality rates for 782 Chinese counties for the periods of 1973-1975 and 2015-2017. We performed hotspot analysis to identify spatial clusters. We used a multivariable negative binomial regression model to estimate the associations between county-level socioeconomic factors and mortality. RESULTS From 1973-1975 to 2015-2017, the age-standardized esophageal cancer-related mortality rate decreased from 27 to 8 per 100,000 person-years in China. By county, 577 (74%) of 782 counties experienced decreasing mortality. Geographic disparities in mortality substantially narrowed, with the gap in mortality rates between 90th and 10th percentile counties decreasing from 55 per 100,000 person-years in 1973-1975 to 16 in 2015-2017. However, clusters of elevated rates persisted across north-central China. Rurality [adjusted mortality rate ratio (MRR) 1.15; 95% confidence interval (CI), 1.10-1.21], per capita gross domestic product (adjusted MRR, 0.95; 95% CI, 0.91-0.98), and percentage of people with a high-school diploma (adjusted MRR, 0.86; 95% CI, 0.84-0.87) in a county were significantly associated esophageal cancer-related mortality rates. CONCLUSIONS China has made substantial progress in reducing esophageal cancer-related mortality and disparities, but the intercounty differences remain large. IMPACT Continued efforts are needed to address the geographical and socioeconomic disparities in esophageal cancer.

Abstract
This study aimed to retrospectively evaluate the treatment strategies and possible prognostic factors in patients with brain metastases (BMs) from esophageal squamous cell carcinoma (ESCC). We retrospectively reviewed 30 patients with BMs from ESCC who were treated at our center between November 2011 and January 2022. Clinicopathological characteristics and clinical outcomes were analyzed. The median follow-up time was 2 (range, 0.5-33) months. The median survival time after diagnosis of BMs was 2 months. The 1-year overall survival (OS) rate was 13.6%. The OS was better in patients with intracranial benefit. Multivariate analysis showed that local treatment of BMs influenced OS. The median survival with or without local treatment of BMs was 4 and 1 month, respectively. The median time interval between the diagnosis of the primary tumor and BMs was 11 (range, 1-156) months. Among these BMs, 55.6% of the BM occurred within the first year after diagnosis of the primary tumor, 66.7% in the first 2 years, and 85.2% in the first 3 years. The median time interval from lung metastasis to BMs was 3 months, from liver metastasis to BMs 3.5 months, and from bone metastasis to BMs 0.5 months. Local treatment of BMs was an independent prognostic factor for patients with BMs from ESCC. Earlier detection followed by an aggressive local therapeutic approach for BMs had a great influence on treatment outcomes as well as the long-term prognosis and quality of life for appropriately selected patients.

Abstract
OBJECTIVE This study aimed to explore the predictive values of serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 199, CA125 and CA724 in the diagnosis of gastrointestinal tumors. METHODS Among patients treated for gastrointestinal tumors at the First Affiliated Hospital of Wannan Medical College between December 2020 and March 2022, 572 patients were reviewed as the tumor group, and 700 healthy subjects from the physical examination center of the same hospital were reviewed as the control group. We evaluated the correlation between serum CEA, CA199, CA125, CA724 levels and pathological features in 572 patients with gastrointestinal tumors.The levels of serum CEA, CA199, CA125 and CA724 were compared between the two groups, and the area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate the diagnostic efficacy of these markers alone and in combination. RESULTS Serum CEA level was correlated with tumor stage and metastasis, and CA199 was correlated with tumor stage, lymph node involvement and metastasis. CA125 and CA724 have no correlation with tumor pathological features. The levels of serum CEA, CA199 and CA125 were significantly increased in the tumor group compared with the control group, while serum CA724 levels did not significantly differ between groups (p > 0.05). In addition, in patients with gastric cancer (GC), esophageal cancer (EC), pancreatic cancer (PC), gallbladder cancer (GBC) or colorectal cancer (CRC), the serum CEA, CA199 and CA125 levels were significantly higher than those in the control group (p < 0.05). However, serum CA724 levels were increased only in CRC patients (p < 0.05). ROC curve evaluation results showed that while CA199, CA125 and CA724 alone had poor diagnostic efficacy in the tumor group, CEA was better. Specifically, CEA had better diagnostic efficacy in GC, PC, GBC and CRC; additionally, CA199 and CA125 had better diagnostic efficacy in PC. However, CA724 showed no diagnostic value in the tumor group and the single gastrointestinal tumor group. For diagnosis with multiple-marker combinations, CEA + CA199 + CA125 had the best diagnostic performance (AUC = 0.776, AUC = 0.650, AUC = 0.896, AUC = 0.840, AUC = 0.793) in the GC, EC, PC, GBC and CRC groups, and the sensitivity of multiple-marker combined detection was better than that of single-marker detection. CONCLUSIONS Serum CA724 has no diagnostic value for gastrointestinal tumors, and it cannot evaluate the pathological status of tumors. Serum CEA has excellent diagnostic efficacy in GC, PC, GBC and CRC, and its expression level is related to tumor stage and metastasis. Additionally, CA199 and CA125 have good diagnostic efficacy in PC. Among them, CA199 level was related to tumor stage, lymph node involvement and metastasis, and CA125 level was not related to pathological status. In addition, the multiple-marker combination CEA + CA199 + CA125 has the best diagnostic efficacy in GC, EC, PC, GBC and CRC.

Abstract
The hemoglobin, albumin, lymphocyte and platelet (HALP) score and the Gustave Roussy immune score (GRIm⁃Score) are prognostic markers in several types of malignant tumors. The prognostic values of HALP score and GRIm⁃Score in concurrent chemoradiotherapy for unresectable esophageal cancer remain unknown. METHODS We enrolled 150 esophageal squamous cell carcinoma (ESCC) patients who underwent concurrent chemoradiotherapy in our institution between 2013 and 2018. The cutoff values for HALP, and GRIm⁃Score were defined by using receiver's operating characteristic curves. Survival was analyzed with the Kaplan- Meier method, with differences analyzed with the log-rank test. Multivariate Cox proportional-hazards models were used to evaluate the prognostic significance of HALP and GRIm for ESCC. RESULTS HALP was significantly associated with the Zubrod ECOG WHO performance status, tumor location, and the clinical tumor, node, metastasis stage. Modified GRIm (mGRIm) was only significantly associated with metastasis / recurrence before radiotherapy (χ2 = 6.25). Univariate Cox regression analysis showed that higher mGRIm (HR 1.9 95%CI 1.3-2.9) and lower HALP (HR 2.4 95%CI 1.6-3.7) were all associated with worse OS. Multivariate COX analysis found that higher mGRIm score (HR 1.7 95%CI 1.1-2.6), and lower HALP score (HR 2 95%CI 1.3-3.2) were both independent risk factors of overall survival. The nomogram c-index in inside validation was 0.66. CONCLUSION Both HALP and mGRIm are independent prognostic factors for patients with unresectable ESCC.

Abstract
BACKGROUND Radical chemoradiation is the standard of treatment for locally advanced squamous cell carcinoma of esophagus and for patients with operable disease, but who are medically unfit or unwilling for surgery. As the esophagus is a central organ, the planning target volume (PTV) is central, lies close to the spinal cord and heart, and is surrounded by the lung, which is a radiosensitive organ. Irradiation of these critical structures is reduced by the use of three-dimensional conformal radiation therapy (3DCRT). Intensity-modulated radiation therapy (IMRT) has the potential to improve the uniformity of dose distribution to the tumor and reduce the dose received by surrounding normal tissues. AIM AND OBJECTIVES 1. To compare the dose distribution, conformity, and homogeneity indices in radical radiotherapy of squamous cell carcinoma of esophagus using 3DCRT and IMRT techniques 2. To compare the doses received by critical structures such as heart, lung, spinal cord, and liver. MATERIALS AND METHODS All cases of squamous cell carcinoma esophagus treated with radical chemoradiation to a dose of 50 Gy in 25 fractions using 3DCRT technique from January 2018 to July 2019 were included. IMRT plans were generated for these cases.The parameters that represent dose distribution to the target volume and the dose received by the organs at risk were obtained from the dose-volume histogram. The difference in the mean values of the parameters between the two techniques was calculated. The statistical significance of the difference was determined using Student's t-test and Wilcoxon signed-rank test. RESULTS The volume of PTV receiving 105% and 107% of prescribed dose was significantly lower with IMRT (3.540% and 0.008%, respectively) compared to 3DCRT (7.654% and 0.623%). The homogeneity index was better with IMRT (0.088 vs. 0.107) than 3DCRT. Conformity index was found to be better with IMRT (1.149 vs. 1.573). Mean heart dose (18.216 vs. 24.591 Gy) and the volume of heart receiving 30 Gy were reduced with IMRT. The volume of lung receiving 20 Gy and the volume receiving 5 Gy were not significantly different between 3DCRT and IMRT. Maximum dose to spinal cord was similar with 3DCRT and IMRT. CONCLUSIONS IMRT avoids areas of excessive irradiation within the PTV. IMRT improves dose conformity to the target volume and homogeneity of dose distribution within the PTV. The cardiac dose is significantly reduced with IMRT. The mean lung dose remains similar to 3DCRT. There is no significant increase in the volume of lung receiving low-dose radiation with IMRT.

Abstract
BACKGROUND Time intervals and number of prior consultations in primary care (PC) are recognised metrics of diagnostic timeliness of cancer and are interrelated. However, whether and how the two measures correlate with each other in the emergency diagnostic pathway is unknown. We investigated the association between the number of prereferral consultations and the length of intervals from PC presentation to cancer diagnosis following emergency referral to hospital. METHODS Patients were eligible if they first consulted in PC and were diagnosed with cancer following emergency or nonemergency referral to hospital. We analysed for differences in PC and diagnostic intervals and number of consultations between emergency and nonemergency presenters and determined their associations by cancer type. Differences in presenting symptoms and stage at diagnosis between populations and according to number of consultations were also examined. RESULTS There were 796 emergency and 865 nonemergency presenters with comparable sociodemographic and comorbidity data. Correlation analysis in emergency presenters revealed a strong positive association between number of consultations and intervals for seven of 13 different cancers, including cancers characterised by high proportions of > 3 consultations and long intervals (pancreatic, lung, and colorectal cancer) and vice versa for others (e.g., endometrial, cervical, or oesophageal cancer). Additionally, emergency presenters with > 3 consultations were more likely than those with 1-2 to report nonspecific symptoms (60 vs. 40%, respectively) and to be diagnosed at a later stage. CONCLUSION System level interventions are needed to reduce unnecessary delays in the emergency diagnostic pathway, particularly in cancer patients with multiple prereferral consultations. The findings also suggest opportunities to reduce the proportion of emergency diagnoses by targeting symptomatic individuals pre-presentation.
