Project description:PurposeStage T1 esophageal cancer (EC) with distant metastasis (DM) is rare and poorly understood. In this study, we aimed to construct and validate a novel nomogram for predicting the probability of DM in T1 EC patients.MethodsA total of 1,663 eligible T1 EC patients were enrolled from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. The patients were randomly divided into training and validation cohorts. Univariate and multivariate logistic analyses in the training cohort were used to identify risk factors related to DM, and then these risk factors were applied to construct the nomogram. Receiver operating characteristic (ROC) curves, the area under the curve (AUC), calibration plots, the Hosmer-Lemeshow (HL) test, and decision curve analysis (DCA) were used to evaluate the nomogram.ResultsAmong the 1,663 patients identified, 143 (8.6%) had DM. Five risk factors (tumor location, lymph node status, tumor length, T1 subtype, and grade) were significant predictors of DM. The AUC values were 0.828 and 0.851 in the training cohort and validation cohort, respectively, revealing good discrimination. The calibration plots in the training cohort and validation cohort both showed good consistency. DCA showed that the nomogram was clinically effective. In addition, the nomogram has a good risk stratification ability to identify patients with different risks according to the nomogram score. In terms of survival analysis, univariate and multivariate Cox analyses showed that age, race, tumor length, grade, lymph node status, M stage and treatment were significant prognostic factors for overall survival (OS). For cancer-specific survival (CSS), the independent prognostic factors were age, tumor length, histology, grade, lymph node status, M stage and treatment.ConclusionThe nomogram could effectively predict the probability of DM in T1 EC patients. It can aid clinicians in detecting high-risk patients and making individual clinical decisions.

Project description:BackgroundLymph node negative (N0) breast cancer can be found coexisting with distant metastasis (DM), which might consequently make clinicians underestimate the risk of relapse and insufficient treatment for this subpopulation.MethodsThe clinicopathological characteristics of N0 breast cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database between January 2010 and December 2015 were retrospectively reviewed. Multivariate logistic and Cox analyses were used to identify independent risk factors in promoting DM and the 1-, 3-, and 5- year cancer-specific survival (CSS) in this subpopulation.ResultSeven factors including age (<40 years), tumor size (>10 mm), race (Black), location (central), grade (poor differentiation), histology (invasive lobular carcinoma), and subtype (luminal B and Her-2 enriched) were associated with DM, and the area under curve (AUC) was 0.776 (95% CI: 0.763-0.790). Moreover, T1-3N0M1 patients with age >60 years at diagnosis, Black race, triple-negative breast cancer subtype, no surgery performed, and multiple DMs presented a worse 1-, 3-, and 5-year CSS. The areas under the ROC for 1-, 3-, and 5- year CSS in the training cohort were 0.772, 0.741, and 0.762, respectively, and 0.725, 0.695, and 0.699 in the validation cohort.ConclusionThe clinicopathological characteristics associated with the risk of DM and the prognosis of female breast cancer patients without lymph node metastasis but with DM are determined. A novel nomogram for predicting 1-, 3-, 5- year CSS in T1-3N0M1 patients is also well established and validated, which could help clinicians better stratify patients who are at a high-risk level for receiving relatively aggressive management.

Project description:It is rare and understudied for patients with stage T1 colorectal cancer to have synchronous distant metastasis. This study was to determine the clinicopathological factors associated with distant metastasis and prognosis. T1 colorectal cancer patients diagnosed between 2010 and 2015 were obtained from the SEER database. Logistic regression was applied to determine risk factors related to distant metastasis. Cox-proportional hazard models were used to identify the prognostic factors for patients with distant metastasis. Among 21,321 patients identified, 359 (1.8%) had synchronous distant metastasis and 1807 (8.5%) had lymph node metastasis. Multivariate analysis revealed that younger age, positive serum CEA, larger tumor size, positive tumor deposit, perineural invasion, lymph node metastasis, histology of non-adenocarcinoma and poorer differentiation were significantly associated with the increased risk of synchronous distant metastasis. Older age, female, Black, positive CEA, positive lymph node metastasis, positive tumor deposit, larger tumor size, no chemotherapy, inadequate lymph node harvesting and no metastasectomy were correlated with worse survival in these patients with synchronous distant metastasis. Patients with metastasis to the liver displayed the highest rate of positive CEA. We conclude that T1 colorectal cancer patients with multiple risk factors need thorough examinations to exclude synchronous distant metastasis. Chemotherapy, adequate lymph node cleaning and metastasectomy are associated with improved survival for those patients with distant metastases. Positive serum CEA may be useful in predicting distant metastases in patients at stage T1.

Project description:BackgroundDespite their excellent prognosis, children and young adults (CAYA) with differentiated thyroid cancer (DTC) tend to have more frequent occurrence of distant metastasis (DM) compared to adult DTC. Data about DM in CAYA from Middle Eastern ethnicity is limited.MethodsMedical records of 170 patients with DTC ≤18 years were retrospectively reviewed. Clinico-pathological factors associated with lung metastasis in CAYA, their clinical presentation and outcome were analyzed. Rick factors related to distant metastasis-free survival (DMFS) for the whole cohort were evaluated.ResultsDM was observed in 27 patients and all were lung metastasis. Lung metastasis was significantly associated with younger age (≤15 years), extrathyroidal extension (ETE), multifocal tumors, bilaterality, presence of lymph node (LN) disease and high post-operative stimulated thyroglobulin (sTg). Highest negative predictive values were seen with low post-operative sTg (97.9%), absence of LN disease (93.8%), absence of ETE (92.2%) and age older than 15 years (92.9%). Post-therapy whole body scan (WBS) identified most of the lung metastasis (21 of 27; 77.8%). Upon evaluating patients response according to ATA guidelines, excellent response was seen in only one patient, while biochemical persistence and structural persistence were seen in 11.1% (3/27) and 77.8% (21/27), respectively. Elevated post-operative sTg (>10ng/ml) was the only risk factor found to be significantly associated with both biochemical persistence (with or without structural persistence (p = 0.0143)) and structural persistence (p = 0.0433). Cox regression analysis identified age and post-operative sTg as independent risk factors related to DMFS. Based on these two risk factors for DMFS, patients were divided into 3 groups: low risk (no risk factors), intermediate risk (1 risk factor) and high risk (both risk factors). 20-year DMFS rates in the low-, intermediate- and high-risk groups were 100.0%, 81.3% and 23.7% respectively (p < 0.0001).ConclusionHigher suspicion for metastatic pediatric DTC should be considered in patients who are young, have LN disease, extrathyroidal extension and elevated post-operative sTg. Persistent disease, despite therapy, is very common and it appears to be related to post-operative sTg level. Hence, risk adaptive management is desirable in CAYA with DTC.

Project description:BackgroundThe distant metastasis in liposarcoma is not thoroughly investigated. Based on a large cohort, we attempted to evaluate the survival in liposarcoma patients with distant metastasis and to reveal the risk factors.MethodsThe records of liposarcoma patients with or without distant metastasis were extracted from the Surveillance, Epidemiology, and End Result (SEER) database from 2010 to 2016. Survival was calculated by the Kaplan-Meier method. Cox hazard regression was scheduled to investigate prognostic factors for liposarcoma patients with distant metastasis. Risk factors for metastasis were identified by the logistic regression analysis.ResultsA total of 227 liposarcomas with distant metastasis were identified in 4,181 patients. The 5-year survival rate for patients with and without metastasis was 12.1% (95% CI: 5.0%-19.0%) and 75.4% (95% CI: 73.6%-77.2%), respectively. Age ≥60 years (HR=1.73; 95% CI: 1.11-2.69) and surgery (HR=0.26; 95% CI: 0.17-0.41) were independent prognostic factors for patients with metastasis. The annual incidence of distant metastasis was from 3.76% to 7.3%. Liposarcoma in trunk (OR=1.69; 95% CI: 1.02-2.79), myxoid type (OR=2.65; 95% CI: 1.16-6.05), grade III (OR=2.62; 95% CI: 1.17-5.88), grade IV (OR=4.07; 95% CI: 1.84-9.00), T2 stage (OR=2.71; 95% CI: 1.15-6.40), and N1 stage (OR=9.44; 95% CI: 4.63-19.26) were associated with the development of metastasis. Homogeneous and heterogeneous factors were found for patients with different metastatic organs.ConclusionsThe survival was significantly dismal in liposarcoma patients with distant metastasis. The risk and prognostic factors provide a reference to clinical screening and prevention for distant metastasis in liposarcoma.

Project description:Tumor microenvironment of metastasis (TMEM), consisting of direct contact between a macrophage, an endothelial cell, and a tumor cell, has been associated with metastasis in both rodent mammary tumors and human breast cancer. We prospectively examined the association between TMEM score and risk of distant metastasis and compared risk associated with TMEM score with that associated with IHC4. We conducted a case-control study nested within a cohort of 3760 patients with invasive ductal breast carcinoma diagnosed between 1980 and 2000 and followed through 2010. Case patients were women who developed a subsequent distant metastasis; control subjects were matched (1:1) on age at and calendar year of primary diagnosis. TMEM was assessed by triple immunostain and IHC4 by standard methods; slides were read by pathologists blinded to outcome. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression, adjusted for clinical variables. A Receiver Operating Characteristic analysis was performed, and the area under the curve was estimated. All statistical tests were two-sided. TMEM score was associated with increased risk of distant metastasis in estrogen receptor (ER)(+)/human epidermal growth factor receptor (HER2)(-) tumors (multivariable OR high vs low tertile = 2.70; 95% CI = 1.39 to 5.26; P trend = .004), whereas IHC4 score had a borderline positive association (OR10 unit increase = 1.06; 95% CI = 1.00 to 1.13); the association for TMEM score persisted after adjustment for IHC4 score. The area under the curve for TMEM, adjusted for clinical variables, was 0.78. Neither TMEM score nor IHC4 score was independently associated with metastatic risk overall or in the triple negative or HER2(+) subgroups. TMEM score predicted risk of distant metastasis in ER(+)/HER2(-) breast cancer independently of IHC4 score and classical clinicopathologic features.

Project description:Circulating microRNAs have recently emerged as a new class of promising non-invasive cancer biomarkers. The purpose of this study was the identification by a high-throughput approach (miRNA microarray) of circulating miRNAs associated with breast cancer-derived distant metastasis. To achieve this goal, we resorted to archival plasma samples collected from patients in the control arm of a randomized clinical trial on stage I breast cancer. We compared plasma miRNA levels in patients that developed distant metastasis after a radical or conservative surgery and in those long-term disease-free. Microarray results were technically and independently validated by Real Time PCR. Subsequent in vitro, in vivo and in silico analyses were performed to investigate the miRNA biological/clinical significance in relation with breast cancer progression. We demonstrated that high circulating miR-1246 levels were associated to distant metastasis and that high tissue expression of this miRNA was correlated with unfavorable outcome in ER+HER2- breast cancer patients. In addition, miR-1246 expression was also found to be related with stem-like features. 64 samples (32 patients with metastasis and 32 patients with no metastasis) were considered from a total of 208 hybridized samples collected between 1987 and 2004 (including 94 paired samples according to tumor ER status, age at drawing, drawing year, time from surgery, 7 additional samples from 'no evidence of disease' (NED) patients, 10 references, 1 healthy donor and 2 replicated samples)

Project description:BackgroundDistant metastases (DM) at presentation in meningiomas is a very rare event, and the incidence and factors predicting this are uncertain. This population-based study also aimed to investigate the prognostic implication of DM at presentation and clinical parameters to prognosticate the overall survival (OS) of meningiomas presenting with DM (M1).MethodsWe accessed the Surveillance, Epidemiology, and End Results program to search for patients who were diagnosed with meningioma between 2004 and 2016. The log-rank test was used to compare Kaplan-Meier survival curves and multivariate Cox regression model was utilized to evaluate the prognostic parameters of meningiomas with DM at presentation.ResultsThe incidence of DM at presentation among all meningiomas was 0.18%. Clinical variables associated with this event were male gender, large tumor size, and WHO grade III. The presence of DM at diagnosis conferred a shorter survival in comparison to those without DM (HR = 2.015; 95% CI = 1.600-2.536). Older patient age, male gender, malignant histology, and the lesser extent of resection were independent prognostic factors that could negatively impact OS of M1 meningiomas. Radiotherapy and chemotherapy were not associated with an improved outcome for these patients.ConclusionOur study highlighted the clinical and prognostic factors of M1 meningiomas. These data suggest that a greater extent of resection is associated with increased OS across a nationwide analysis and emphasize the need to establish the standards of care in these patients.

Project description:BackgroundAlthough the overall global incidence of gastric cancer has been declining, the number of new cases in people under the age of 50 is increasing, which is related to metastasis, late pathological stages, and poor prognosis. There is a scarcity of large-scale studies to evaluate and predict distant metastasis in patients with early-onset gastric cancer.MethodsFrom January 2010 to December 2019, data on early-onset GC patients undergoing surgery were gathered from the Surveillance, Epidemiology, and End Results (SEER) database. We investigated the independent risk factors for distant metastasis in patients with early-onset gastric cancer. Based on these risk factors, we developed a nomogram to predict distant metastasis. The model underwent internal validation on the test set and external validation on 205 patients from the First Affiliated Hospital of Sun Yat-sen University and the seventh Affiliated Hospital of Sun Yat-sen University. The novel nomogram model was then evaluated using the receiver operating characteristic (ROC) curve, calibration, the area under the curve (AUC), and decision curve analysis (DCA). The training set nomogram score was used to classify the different risk clusters of distant metastasis.ResultsOur study enrolled 2217 patients after establishing the inclusion and exclusion criteria, with 1873 having no distant metastasis and 344 having distant metastasis. The tumor size, total lymph nodes, whether or not receiving radiotherapy and chemotherapy, T stage, and N stage were significant predictors of advanced distant metastasis (p < 0.05). The AUC of the ROC analysis demonstrated our model's high accuracy. Simultaneously, the prediction model shows high stability and clinical practicability in the calibration curve and DCA analysis.ConclusionsWe developed an innovative nomogram containing clinical and pathological characteristics to predict distant metastasis in patients younger than 50 years old with gastric cancer. The tool can alert clinicians about distant metastasis and help them develop more effective clinical treatment plans.
