OCANTO, Abrahams et al. Relationship between haematological markers and patological complete response to neoadjuvant treatment in locally advanced rectal cancer. JONNPR [online]. 2020, vol.5, n.11, pp.1356-1366.  Epub 18-Dez-2023. ISSN 2529-850X.  https://dx.doi.org/10.19230/jonnpr.3754.

Introduction.

Multiple haematological markers of inflammation might be related with poor prognosis in oncological patients.

Purpose.

This study evaluated whether changes of haematological markers before and after chemoradiotherapy treatment in rectal cancer might be associated to pathological complete response.

Material and Methods.

Medical records of 140 patients with rectal cancer who received neoadjuvant radiotherapy followed by surgical resection were retrospectively review. Complete bloods counts (CBC) was measured days before and after period of RT. We assessed white blood cells count (WBC), hemoglobin levels (Hb), neutrophils count, lymphocytes count, monocytes count, neutrophil-to-lymphocye ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR).

Results.

The overall rate of pCR was 17,5%. Hematological markers had a statistically significant decrease after CRT treatment (p<0,05), however in our analysis they do not predict complete pathological response.

Conclusion.

Haematological markers before and after neoadjuvant treatment do not predict tumor responses in this study. However, a larger sample can show statistically significant results, especially in monocytes ratio.
