The survival benefit of lymph node dissection in resected T1-2, cN0 supraglottic cancer: A population-based propensity score matching analysis. Head Neck 2020; 43:1300-1310. [PMID: 33372331 DOI: 10.1002/hed.26596] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 12/04/2020] [Accepted: 12/17/2020] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND The survival benefit of clinically negative cervical lymph nodes (cN0) in patients with T1-2 supraglottic cancer (SC) remains unclear. This study aimed to comprehensively evaluate the prognostic value of lymph node dissection (LND) in patients with T1-2, cN0 SC. METHODS We included 1036 confirmed T1-2, cN0 SC patients with clinicopathological characteristics between 2004 and 2015, based on the Surveillance, Epidemiology, and End Results program (SEER) database. The association between LND and overall survival (OS) was investigated by the Kaplan-Meier method. RESULTS Before propensity score matching (PSM), patients selected for LND had better OS, compared to patients did not receive LND (5-year OS: 62.6% vs 51.2%, respectively; p = 0.011). After PSM, the LND group also present significant improvement in prognosis (5-year OS: 64.3% vs 51.7%, respectively; p < 0.01). CONCLUSIONS LND was significantly associated with a more favorable prognosis compared with non-LND in patients with T1-2, cN0 SC.

Xiao W, Liang H, Zhang H, Jia R, Yang Y, Wang Y, Tang P, Yu Z. Ratio between negative and positive lymph nodes is a novel prognostic indicator for patients with esophageal cancer: A Surveillance, Epidemiology and End Results database analysis. Thorac Cancer 2020; 11:3490-3500. [PMID: 33034409 PMCID: PMC7705634 DOI: 10.1111/1759-7714.13688] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 09/20/2020] [Accepted: 09/20/2020] [Indexed: 12/14/2022] Open
Abstract
Background The aim of this study was to explore whether the ratio between negative and positive lymph nodes (RNP) could predict the overall survival (OS) of esophageal cancer (EC) patients with lymph node metastasis following esophagectomy. Methods We utilized the Surveillance, Epidemiology and End Results (SEER) database to include the records of 2374 patients with lymph node metastases post‐surgery. All patients were randomly assigned into the training cohort (n = 1424) and validation cohort (n = 950). Multivariate Cox regression analyses were performed to identify independent prognostic factors. A novel RNP ‐based TRNPM staging system was proposed. The prognostic value of N, RNP, TNM and TRNPM staging system was evaluated using the linear trend χ2 test, likelihood ratio χ2 test, and Akaike information criterion (AIC) to determine the potential superiorities. We constructed nomograms to predict survival in both cohorts, and the calibration curves confirmed the predictive ability. Results Univariate analyses showed that N and RNP stage significantly influenced the OS of patients. Multivariate analyses revealed that RNP was an independent prognostic predictor in both the training and validation cohorts. For the stratification analysis in the two cohorts, we found significant differences in the prognosis of patients in different RNP groups on the basis of the different N stages and the number of dissected lymph nodes. In addition, the lower AIC value of RNP stage and TRNPM staging system represented superior predictive accuracy for OS than the N stage and TNM staging system, respectively. Furthermore, the calibration curves for the probability of three‐ and five‐year survival showed good consistency between nomogram predictive abilities and actual observation. Conclusions We demonstrated that compared to the classical pathological lymph nodal staging system, the RNP stage showed superior predictive accuracy for OS and can serve as a more effective prognostic guidance for lymph node positive EC patients.

[PMID: 32149032 PMCID: PMC7049255 DOI: 10.7717/peerj.8692] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Accepted: 02/05/2020] [Indexed: 12/13/2022] Open
Abstract
Purpose The relationship between examined lymph nodes (ELN) and survival has been confirmed in several single early-stage malignancies. We studied the association between the ELN count and the long-term survival of T1-2N0M0 double primary non-small cell lung cancer (DP-NSCLC) patients after surgery, based on the Surveillance, Epidemiology and End Results (SEER) database. Methods A total of 948 patients were identified and their independent prognostic factors were analyzed. These factors included the ELN count, which related to overall survival (OS) and the cancer-specific survival (CSS) of synchronous (n = 426) and metachronous (n = 522) T1-2N0M0 DP-NSCLC patients after surgery. Results X-tile analysis indicated that the cutoff value for the sum of ELNs was 22 for both OS and CSS in the synchronous DP-NSCLC group. Patients with a sum of ELNs >22 were statistically more likely to survive than those with ≤22 ELNs. X-tile analysis revealed that the ELN count of the second lesion was related to both OS and CSS in the metachronous DP-NSCLC group. The optimal cutoff value was nine. These results were confirmed using univariate and multivariate Cox regression analyses. Conclusion Our findings indicate that ELN count was highly correlated with the long-term survival of T1-2N0M0 double primary NSCLC patients after surgery.
