Pretreatment total lymphocyte count as a prognostic factor of survival in patients with recurrent cervical cancer after definitive radiation-based therapy: a retrospective study.

ABSTRACT:

Objective

This study evaluated the association between pretreatment total lymphocyte count (TLC) and overall survival (OS) in patients with recurrent cervical cancer.

Methods

We retrospectively reviewed 290 patients with recurrent cervical cancer with definite complete responses to either definitive radiotherapy or concurrent chemoradiotherapy between January 2009 and December 2022. The associations between pretreatment TLC and progression-free survival (PFS) and OS rates were evaluated.

Results

Ninety-three patients (32%) had a pretreatment TLC <1,000 cells/mm3. Patients with a pretreatment TLC <1,000 cells/mm3 had lower treatment response rates than their counterparts (P=0.045). The OS and PFS rates were significantly higher in patients with pretreatment TLC ≥1,000 cells/mm3 than in those with pretreatment TLC <1,000 cells/mm3 (10.74 vs. 3.89 months, P<0.0001; 8.32 vs. 4.97 months, P=0.042; respectively). Moreover, pretreatment TLC ≥1,000 cells/mm3 was identified as an independent prognostic factor for OS in both univariate analysis (hazard ratio [HR], 0.57; 95% conficence interval [CI], 0.44-0.74; P<0.001) and multivariate analysis (HR, 0.64; 95% CI, 0.47-0.86; P=0.003). However, TLC ≥1,000 cells/mm3 was identified as a prognostic factor for PFS only in univariate analysis (HR, 0.71; 95% CI, 0.51-0.99; P=0.043) but not in the multivariate analysis (HR, 0.81; 95% CI, 0.55-1.18; P=0.3).

Conclusion

Pretreatment TLC was associated with treatment response and was identified as an independent prognostic factor associated with the survival outcomes of patients with recurrent cervical cancer.

Project description:BackgroundImmunotherapy has become the standard of treatment for recurrent metastatic esophageal cancer (EC), and the value of efficacy predictive markers represented by programmed death-ligand 1 (PD-L1) is limited. The purpose of this study is to analyze the prognostic value of peripheral blood absolute lymphocyte count (ALC) at baseline in patients with recurrent metastatic EC treated with immunotherapy, and to further investigate the relationship between the minimal ALC value (Min ALC) and radiotherapy (RT) parameters.MethodsThe main inclusion criteria were: histologically or imaging confirmed recurrent or metastatic EC; complete routine blood test data. A total of 105 patients were included in a single-center institution, 65 of whom had previously received RT. The optimal cut-off value for baseline lymphopenia was determined by the receiver operating characteristic (ROC) curve. The prognostic value of baseline phase lymphopenia for immunotherapy were determined by cox regression analysis and the associated factors affecting lymphopenia were explored by logistic regression analysis.ResultsThe cut-off value for baseline ALC predicting 1-year overall survival (OS) was 625 cells/µL. The OS was significantly lower in the lymphopenia group (ALC ≤625 cells/µL) than in the non-lymphopenia group (ALC >625 cells/µL) (median OS: 6 vs. 12 months, P=0.002). Multivariate analysis showed that pre-immunotherapy lymphopenia was an important factor influencing patient prognosis [hazard ratio (HR): 1.771, 95% confidence interval (CI): 1.051-2.985; P=0.032)] (adjusted for clinical factors including sex, age, tumor location, histology, degree of differentiation, distant metastasis, use of RT). Patients with a previous grade 4 (G4) Min ALC during RT were more likely to develop pre-immunotherapy lymphopenia following diagnosis of recurrent metastasis [odds ratio (OR): 10.809, 95% CI: 2.185-53.471; P=0.004]. Planning target volume (PTV) volume greater than 521.2 cm3 (OR: 19.981, 95% CI: 1.372-290.985; P=0.028) was an independent risk factor affecting the G4 Min ALC during RT.ConclusionsLymphopenia is associated with a poorer immunotherapy prognosis in patients with recurrent metastatic EC and those with previous G4 Min ALC after RT. RT-related parameters, especially irradiation volume, can significantly affect lymphocyte counts.
