Prognostic nutritional index and neutrophil-lymphocyte ratio predict toxicities and prognosis in patients with cervical cancer treated with curative radiochemotherapy.

This study aimed to investigate the influence of immunonutritional factors on treatment-related toxicities and survival outcomes in patients with cervical cancer undergoing definitive radiochemotherapy. Patients with cervical cancer who received curative radiochemotherapy between 2016 and 2021 were retrospectively investigated. Pretreatment prognostic nutritional index (PNI), neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) were measured. Survival outcomes, acute and late toxicities were evaluated. Among the 138 patients, those with larger tumor diameters had significantly lower pre-treatment PNI (p = 0.005). Pre-treatment immunonutritional factors were predictive of clinical survival, whereas post-treatment factors did not correlate with prognosis. Patients with low pre-treatment PNI (<49.5) or high NLR (>2.4) had shorter progression-free survival (PFS, HR: 1.86, p = 0.045 for PNI; HR: 3.15, p = 0.002 for NLR) and overall survival (OS, HR: 1.80, p = 0.048 for PNI; HR: 3.83, p = 0.015 for NLR). High pre-treatment NLR was associated with an increased risk of acute diarrhea (p = 0.049) and late severe toxicities (p = 0.046). Combined analysis revealed that pre-treatment good nutritional status and low systemic inflammation were linked to longer PFS (p = 0.007) and OS (p = 0.002), and poor nutritional status and substantial systemic inflammation were associated with higher rates of late severe toxicities (p = 0.036), with higher prognostic value in advanced stage patients. Pretreatment immunonutritional measures serve as quantitative biomarkers for predicting survivals and treatment toxicities in patients with cervical cancer treated with definitive radiochemotherapy.

Prognostic biomarkers in metastatic colorectal cancer: delta prognostic nutritional index, delta neutrophil to lymphocyte ratio, and delta platelet to lymphocyte ratio.

The aim of this study is to determine the prognostic value of the prognostic nutritional index (PNI), the neutrophil to lymphocyte ratio (NLR), and the platelet to lymphocyte ratio (PLR) and their dynamic changes on survival outcomes in metastatic colorectal cancers (mCRC). The data of 199 patients with mCRC were retrospectively analyzed. To evaluate the temporal relation between the PNI, NLR, and PLR values and survival, pre-chemotherapy PNI, NLR, and PLR levels were assessed from peripheral blood cell counts on admission; post-chemotherapy PNI, NLR, and PLR levels were assessed with follow-up blood cell counts within two weeks after chemotherapy; and the difference between pre-chemotherapy PNI, NLR, and PLR levels and post-chemotherapy PNI, NLR, and PLR levels was evaluated as delta PNI, delta NLR, and delta PLR. The median PNI, PLR, and NLR were 39.01, 150.2 and 2.53 before chemotherapy and 38.2, 146.6, and 3.31 after chemotherapy, respectively. The median OS was 23.7 months (95%CI:17.8-29.7) and 28.9 months (95%CI:24.8-33.08) for pre-chemotherapy PNI level < 39.01 vs. PNI level ≥ 39.01, respectively(p = 0.035) The positive delta PNI was significantly higher for OS than the negative delta PNI(p < 0.009). Delta PLR and delta NLR were not significant for OS and PFS(p > 0.05 for all). The results of this study clearly show that the negative delta PNI to be an independent predictor of poor OS and poor PFS in patients with colon cancer who received first line treatment. In addition, delta NLR and delta PLR were shown not to predict survival outcomes.
