Long-term analysis of hematological parameters as predictors of recurrence patterns and treatment outcomes in cervical cancer patients undergoing definitive chemoradiotherapy.

PURPOSE: This study sought to determine the predictive and prognostic value of clinicopathological parameters and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and hemoglobin (Hgb) level in predicting recurrence patterns and locoregional relapse-free survival (LRFS) and distant metastasis-free survival (DMFS) in cervical cancer patients receiving definitive chemoradiotherapy (ChRT). METHODS: This study included 261 cervical cancer patients treated with ChRT. The primary endpoints were the predictors of local recurrence (LR) and distant metastasis (DM), whereas the secondary endpoints were LRFS and DMFS. The association of survival with potential prognostic factors was analyzed using Cox regression analysis, and the predictors of LR and DM were identified using logistic regression analysis. RESULTS: The median follow-up time was 10.9 years. Recurrences occurred in 132 patients (50.6%) within a median of 11.2 months after definitive ChRT. NLR and PLR values were significantly higher in patients with LR and DM than in those without, with no significant differences in Hgb levels in patients with or without LR and DM. In the multivariable logistic regression analysis, lymph node metastasis, elevated NLR, and low Hgb level were significantly correlated with LR and DM. In the multivariable analysis, large tumor size, presence of lymph node metastasis, and elevated NLR were the independent predictors for poor LRFS and DMFS, and Hgb level was an additional prognostic factor for DMFS. CONCLUSION: Hematological markers, particularly NLR and Hgb, may serve as cost-effective and readily accessible indicators for predicting recurrence and survival in cervical cancer patients, contributing to their practical use in routine assessments.

Addressing radiotherapy-induced fibrosis: the potential of platelet-rich plasma and infliximab for improved breast cancer management.

Breast cancer treatment encompasses various therapeutic modalities, including surgery, radiotherapy, and chemotherapy. Breast-conserving surgery has been an integral part of breast cancer management. However, radiotherapy, an important component of breast cancer management, can lead to complications, particularly fibrosis, affecting reconstructive surgery outcomes. We conducted an in vivo study using 48 female Wistar Albino rats, employing segmental mastectomy and radiotherapy to simulate post-mastectomy conditions. The rats were divided into six groups: control, mastectomy, mastectomy + radiotherapy, mastectomy + platelet-rich plasma (PRP) + radiotherapy, mastectomy + infliximab + radiotherapy, and mastectomy + infliximab + PRP + radiotherapy. Edema, hyperemia, inflammation, and fibrosis were assessed as indicators of tissue response. Histopathological analysis revealed that mastectomy + infliximab and mastectomy + infliximab + PRP groups showed significant reductions in fibrosis compared to other groups. Edema, hyperemia, and inflammation were also less severe in these groups compared to the control group. Radiotherapy-induced fibrosis is a major concern in breast reconstruction. Our study suggests that local PRP application and systemic infliximab administration, either alone or in combination, could mitigate the adverse effects of radiotherapy. This approach has the potential to improve reconstructive outcomes in patients undergoing or having the possibility to undergo radiotherapy. This is the first study showing the effectiveness of infliximab and PRP combination on wound healing. The provided experimental rat model might offer guidance for further research. This study provides insights into optimizing outcomes in reconstructive breast surgery, paving the way for further research and clinical studies.
