Monocytes-to-lymphocytes ratio increases the prognostic value of circulating tumor cells in non-small cell lung cancer: a prospective study.

ABSTRACT:

Background

Circulating tumor cells (CTCs) has shown important prognostic value in non-small cell lung cancer (NSCLC). However, the present low sensitivity of CTC capture technology restricts their clinical application. This study aims to explore the feasibility of combining the peripheral blood cell (PBC)-derived inflammation-based score with CTCs to increase the prognostic value of CTCs in NSCLC.

Methods

Sixty volunteers diagnosed with NSCLC were recruited. CTC count and six inflammation-based scores were examined and the association with progression-free survival (PFS) and overall survival (OS) was explored. The changes in the CTC counts before and after the immunotherapy were observed.

Results

Multivariate analysis showed that CTCs >7 [hazard ratio (HR) =9.07; 95% confidence interval (CI): 3.68-22.37, P<0.001] and monocytes-to-lymphocytes ratio (MLR) > 0.2 (HR =3.07; 95% CI: 1.21-7.84; P=0.01) were associated with shorter OS and PFS in patients with NSCLC. Patients with CTCs >7 and MLR >0.2 had 12.30 times increased risk of death (P<0.001) and 6.10 times increased risk of disease progression (P=0.002) compared with those with CTCs ≤7 and MLR ≤0.2. Decreased CTC counts after immunotherapy were closely related to disease control (r=0.535, P=0.01).

Conclusions

CTCs and MLR are both independent risk factors for prognosis in patients with NSCLC. The combination of CTCs with MLR significantly increased the prognostic value of CTCs, which would contribute to stratification of NSCLC patients and providing precise treatment. Dynamic monitoring of CTCs efficiently shows the immunotherapy response in NSCLC.

Project description:BackgroundThe assessment of tumor-infiltrating lymphocytes (TILs) has led to the development of various immunotherapies beyond their predictive potential in gastrointestinal malignancies. However, the clinicopathologic and prognostic values of TILs have yet to be well elucidated in distal extrahepatic bile duct carcinoma (DBDC).Patients and methodsWe evaluated stromal TILs (sTILs) and intraepithelial TILs (iTILs) in 405 surgically resected DBDCs to analyze their correlations with overall survival (OS) and recurrence-free survival (RFS) and with clinicopathologic parameters according to the eighth edition of the American Joint Committee on Cancer scheme.ResultsHigh levels of sTIL density (sTILHigh; >5%) and iTIL count (iTILHigh; >3) were found in 245 (61%) and 74 cases (18%), respectively. sTILHigh was more commonly found in larger tumors (P = 0.048) diffusely involving both intra- and extrapancreatic bile ducts (P = 0.013), in tumors with lower T category (P = 0.002), and in tumors without pancreatic (P = 0.003) or duodenal invasion (P < 0.001). iTILHigh was associated with tumors with papillary or nodular growth pattern (P < 0.001) without perineural invasion (P = 0.006). Both sTILHigh and iTILHigh significantly predicted better OS (P = 0.009 and 0.036, respectively) and RFS (P = 0.003 and 0.026, respectively). sTIL consistently provided prognostic predictability in OS, even when tested with different quantitative cut-offs and prognostically stratified OS (P = 0.006) and RFS (P = 0.005) on multivariate analysis. The survival benefit of sTILHigh persisted regardless of the stage in both OS (P = 0.010 for lower stages I and II and P = 0.001 for higher stages III and IV) and RFS (P = 0.004 and 0.025 for lower- and higher-stage tumors, respectively).ConclusionssTILs were superior to iTILs in predicting survival, and it was shown to be a strong prognosticator for DBDC patients regardless of the stage. The utility of sTILs may extend beyond prognostication to aid in predicting therapeutic responses in DBDC patients.

Project description:BackgroundSeveral recent studies have reported the increasing application of preoperative circulating tumor DNA (ctDNA) as a biomarker of tumor burden for guiding potential postoperative treatment strategies.MethodsA meta-analysis of prospective/retrospective cohort studies was conducted to compare the prognosis of preoperatively genetically positive and genetically negative NSCLC patients. The endpoints used in the included studies were overall survival (OS) and recurrence-free survival (RFS). The objective of the meta-analysis was to comprehensively explore the prognostic value of preoperative ctDNA for patients with non-small-cell lung cancer (NSCLC) and its significance in guiding postoperative adjuvant therapy (AT) in patients with NSCLC.ResultsThe preliminary analysis identified 1565 studies, among which only 11 studies fulfilled the eligibility criteria and were finally included in the present systematic review and meta-analysis. The statistical results revealed that the expression of preoperative ctDNA was associated with worse RFS (HR = 3.00; 95% CI 2.26-3.98; I2 = 0%) and OS (HR = 2.77; 95% CI 1.67-4.58; I2 = 0%), particularly in lung adenocarcinoma (LUAD) patients (RFS: HR = 3.46; 95% CI 2.37-5.05; I2 = 0%; OS: HR = 3.52; 95% CI 1.91-6.49; I2 = 0%) and patients with I-II stage of NSCLC (RFS: HR = 2.84; 95% CI 1.88-4.29; I2 = 0%; OS: HR = 2.60; 95% CI 1.43-4.74; I2 = 0%). Moreover, compared to patients with negative preoperative ctDNA, patients with positive preoperative ctDNA presented greater survival benefits (HR = 0.39; 95% CI 0.22-0.67; I2 = 2%) from postoperative AT.ConclusionThe evaluation of the prognostic value of preoperative ctDNA revealed that preoperative ctDNA might be used as a prognostic biomarker for patients with LUAD or those with stage I-II NSCLC. In addition, postoperative AT is recommended for NSCLC patients with positive preoperative ctDNA, regardless of the disease stage and subtype.
