The combined role of PET/CT metabolic parameters and inflammatory markers in detecting extensive disease in small cell lung cancer
The combined role of inflammatory markers [including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), and systemic immune-inflammation index (SII)] and PET/CT metabolic parameters [including maximum standardized uptake value (SUVmax), mean standard...

Zusammenfassung: | The combined role of inflammatory markers [including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), and systemic immune-inflammation index (SII)] and PET/CT metabolic parameters [including maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and TLG (total lesion glycolysis)] at baseline in evaluating the binary stage [extensive-stage disease (ED) and limited-stage disease (LD)] of small cell lung cancer (SCLC) is unclear. In this study, we verified that high metabolic parameters and inflammatory markers were related to the binary stage of SCLC patients, respectively (
p
< 0.05). High inflammatory markers were also associated with high MTV and TLG in patients with SCLC (
p
< 0.005). Moreover, the incidences of co-high metabolic parameters and inflammatory markers were higher in ED-SCLC (
p
< 0.05) than those in LD-SCLC. Univariate logistic regression analysis demonstrated that
Co-high
MTV/NLR,
Co-high
MTV/MLR,
Co-high
MTV/SII,
Co-high
TLG/NLR,
Co-high
TLG/MLR, and
Co-high
TLG/SII were significantly related to the binary stage of SCLC patients (
p
= 0.00). However, only
Co-high
MTV/MLR was identified as an independent predictor for ED-SCLC (odds ratio: 8.67, 95% confidence interval CI: 3.51–21.42,
p
= 0.000). Our results suggest that co-high metabolic parameters and inflammatory markers could be of help for predicting ED-SCLC at baseline. Together, these preliminary findings may provide new ideas for more accurate staging of SCLC. |
