The Impact of Hematologic Parameters on Histopathologic Features of Colorectal Cancer

Area of Science:

• Oncology
• Hematology
• Pathology

Background:

• Colorectal cancer (CRC) research is actively exploring novel biomarkers for prognosis.
• Hematological parameters are being investigated for their potential predictive value in CRC.
• This study focuses on accessible inflammatory markers: platelet (PLT) levels, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-CRP ratio (LCR).

Purpose of the Study:

• To evaluate the relationship between specific hematological parameters and histopathological features in colorectal adenocarcinoma.
• To determine if PLT, NLR, PLR, and LCR can serve as indicators of prognosis in CRC patients.

Main Methods:

• A retrospective cross-sectional study included 111 patients with colorectal adenocarcinoma.
• Exclusion criteria included infection, recurrent CRC, hematological disease, and neoadjuvant therapy.
• Data collected included demographic, histopathological, and preoperative blood parameters (PLT, NLR, PLR, LCR, CRP).

Main Results:

• Platelet count was significantly associated with lymphovascular invasion, perineural invasion, radial surgical margin status, lymph node metastasis, tumor localization, and stage.
• Neutrophil-to-lymphocyte ratio (NLR) showed significant correlations with perineural invasion, lymph node metastasis, and tumor stage.
• No significant relationships were found between platelet-to-lymphocyte ratio (PLR) or lymphocyte-to-CRP ratio (LCR) and the evaluated histopathological features.

Conclusions:

• Perineural invasion, lymph node metastasis, and tumor stage are potentially linked to hematologic parameters in colorectal cancer.
• Platelet count and NLR may hold prognostic significance, warranting further investigation.
• Larger studies are recommended to validate these hematologic parameters as reliable prognostic markers for colorectal cancer.
