Neutrophil-to-lymphocyte ratio and C-reactive protein-to-albumin ratio as prognostic factors for unresectable advanced or recurrent gastric cancer

Proposal of a nutrition screening algorithm for patients with incurable cancer receiving palliative care: Data from a prospective cohort

OBJECTIVE

To propose and evaluate the clinical utility of a new nutrition screening algorithm, NutriPal, to detect the degree of nutritional risk in patients with incurable cancer receiving palliative care.

METHODS

It is a prospective cohort conducted in an oncology palliative care unit. The NutriPal algorithm was used in a three-step process: (i) administration of the Patient-Generated Subjective Global Assessment short form; (ii) calculation of the Glasgow Prognostic Score; and (iii) application of the algorithm to classify patients into four degrees of nutritional risk. The higher the degrees of NutriPal, the worse the nutritional risk, comparing nutritional measures, laboratory data, and overall survival (OS).

RESULTS

The study included 451 patients that were classified using the NutriPal. They were allocated to the degrees: 1 (31.26%), 2 (27.49%), 3 (21.73%), and 4 (19.71%). Statistically significant differences were found in most of the nutritional and laboratory parameters and in OS with each increment in the NutriPal degrees, and OS was reduced (log-rank <0.001). In addition, NutriPal was able to predict a 120-day mortality: there was a significantly higher risk of death in the patients classified as degrees 4 (hazard ratio [HR], 3.03; 95% confidence interval [95% CI], 2.18-4.19), 3 (HR, 2.01; 95% CI, 1.46-2.78), and 2 (HR, 1.42; 95% CI; 1.04-1.95) than in those classified as degree 1. It also showed good predictive accuracy (concordance statistic, 0.76).

CONCLUSION

The NutriPal is associated to nutritional and laboratory parameters and can predict survival. It could therefore be incorporated into clinical practice for patients with incurable cancer receiving palliative care.

Prognostic significance of the cachexia index in patients with unresectable advanced gastric cancer receiving palliative chemotherapy: a retrospective single-center study

PURPOSE

To investigate the prognostic utility of the cachexia index (CXI) in unresectable advanced gastric cancer (UAGC).

METHODS

The relationship between CXI and the outcomes was evaluated in 102 patients with UAGC who had received first-line palliative 5-fluorouracil-based chemotherapy between January 2012 and December 2021.

RESULTS

The median survival time (MST) from first-line chemotherapy initiation was 16.2 months, and the cohort included 60 and 42 patients with high and low CXIs, respectively, based on the optimal CXI cutoff. The rates of patients with a performance status score of 0, recurrence, third-line chemotherapy, and all grade 3-4 side effects, including febrile neutropenia (FN), were significantly higher in the CXIhigh group than in the CXIlow group. The prognosis based on MST was significantly better in the CXIhigh group than in the CXIlow group (22.5 vs. 11.6 months, p < 0.001). According to a multivariate analysis, a low CXI and performance status score of 1-2 were poor prognostic factors.

CONCLUSIONS

Patients with UAGC and a low CXI had poorer prognoses and more frequent grade 3-4 side effects, including FN, than those with a high CXI. Patients with UAGC and a low CXI should be carefully managed to control for side effects to receive subsequent treatment.

Neural Invasion is an Independent Prognostic Factor in Young and Lymph Node Negative Gastric Cancer Patients Underwent Curative Gastrectomy

BACKGROUND

The prognostic significance of neural invasion (NI) in gastric cancer (GC) has not been established. This study is to investigate the characteristic and prognostic value of NI in GC.

METHODS

592 patients who had undergone gastrectomy for GC were retrospectively analyzed. NI was defined when cancer cells infiltrated into the perineurium or neural fascicles by hematoxylin and eosin staining of surgical specimens. NI and the other clinical factors were analyzed.

RESULTS

NI was detected in 270 of the 592 patients. NI was associated with tumor size, site, depth of invasion, lymph node metastasis, TNM stage, D dissection, tumor differentiation, Lauren classification, and blood vessel invasion. NI was associated with the overall survival. Multivariate analysis indicated that NI was not an independent prognostic factor for total patients, while NI independently predicted prognosis for age < 60 and lymph node metastasis negative patients by subgroup analysis. Concomitant existence of NI with tumor size ≥3cm, TNM stage III, or diffused Lauren classification independently predicted prognosis.

CONCLUSIONS

The frequency of NI is high in GC patients and increases with disease progression. NI is related to poor survival in GC patients who underwent curative gastrectomy and provides independent prognostic value for young and lymph node metastasis negative patients.

The neutrophil-to-lymphocyte ratio as a new prognostic factor in cancers: a narrative review

The increasing incidence of cancer globally has highlighted the significance of early diagnosis and improvement of treatment strategies. In the 19th century, a connection was made between inflammation and cancer, with inflammation recognized as a malignancy hallmark. The neutrophil-to-lymphocyte ratio (NLR), calculated from a complete blood count, is a simple and accessible biomarker of inflammation status. NLR has also been proven to be a prognostic factor for various medical conditions, including mortality classification in cardiac patients, infectious diseases, postoperative complications, and inflammatory states. In this narrative review, we aim to assess the prognostic potential of NLR in cancer. We will review recent studies that have evaluated the association between NLR and various malignancies. The results of this review will help to further understand the role of NLR in cancer prognosis and inform future research directions. With the increasing incidence of cancer, it is important to identify reliable and accessible prognostic markers to improve patient outcomes. The study of NLR in cancer may provide valuable insights into the development and progression of cancer and inform clinical decision-making.

Clinical Effect of the C-Reactive Protein to Serum Albumin Ratio in Patients with Metastatic Gastric or Gastroesophageal Junction Cancer Treated with Trifluridine/Tipiracil

Trifluridine/tipiracil (FTD/TPI) is an oral anticancer agent used as a third- or later-line treatment for patients with metastatic gastric cancer/gastroesophageal junction cancer (mGC/GEJC). The C-reactive protein-to-serum albumin ratio (CAR) is an inflammation-based prognostic marker in gastric cancer. This retrospective study evaluated CAR's clinical significance as a prognostic factor in 64 patients with mGC/GEJC administered FTD/TPI as a third- or later-line therapy. Patients were categorized into high- and low-CAR groups based on pre-treatment blood data. This study evaluated associations between CAR and overall survival (OS), progression-free survival (PFS), clinicopathological features, treatment efficacy, and adverse events. The high-CAR group had significantly worse Eastern Cooperative Oncology Group performance status, a higher prevalence of patients administered with a single course of FTD/TPI, and a higher rate of patients not administered chemotherapy after FTD/TPI therapy than the low-CAR group. Median OS and PFS were significantly poorer in the high-CAR group than in the low-CAR group (113 vs. 399 days; p < 0.001 and 39 vs. 112 days; p < 0.001, respectively). In multivariate analysis, high CAR was an independent prognostic factor for OS and PFS. The overall response rate was not significantly different between the high- and low-CAR groups. Regarding adverse events, the high-CAR group had a significantly lower incidence of neutropenia and a higher incidence of fatigue than the low-CAR group. Therefore, CAR may be a potentially useful prognostic factor for patients with mGC/GEJC treated with FTD/TPI as third- or later-line chemotherapy.

Predictive role of preoperative geriatric nutritional risk index for clinical outcomes in surgical gastric cancer patients: A meta-analysis

PURPOSE

The association between the preoperative Geriatric Nutritional Risk Index (GNRI) and postoperative short-term and long-term clinical outcomes remains unclear. The aim of this meta-analysis was to identify the predictive role of the preoperative GNRI for postoperative clinical outcomes of gastric cancer patients based on current evidence.

METHODS

Several databases were searched up to July 28, 2022. The primary and secondary outcomes were long-term survival, including overall survival (OS), cancer-specific survival (CSS) and postoperative complications. Meanwhile, the hazard ratios (HRs) and relative risks (RRs) with 95% confidence intervals (CIs) were combined to assess the association of preoperative GNRI with postoperative survival and complications separately. The results Eight studies involving 4,189 patients were included, and they were all from Japan. The pooled results demonstrated that a lower preoperative GNRI was significantly related to worse OS (HR = 1.72, 95% CI: 1.18-2.53, P = 0.005) and CSS (HR = 1.67, 95% CI: 1.20-2.32, P = 0.002). Meanwhile, a lower preoperative GNRI was significantly associated with postoperative complications (RR = 1.97, 95% CI: 1.51-2.58, P < 0.001). Further analysis focusing on elderly patients showed similar results.

CONCLUSION

Preoperative GNRI is related to postoperative short-term and long-term clinical outcomes of Japanese gastric cancer patients, and a lower GNRI predicts poorer prognosis.

Pretreatment C-Reactive Protein/Albumin Ratio is Associated With Poor Survival in Patients With 2018 FIGO Stage IB-IIA HPV-Positive Cervical Cancer

Objectives: The present study aimed to identify the predictive value of inflammatory indexes stratified according to human papillomavirus (HPV) infection status in women with FIGO 2018 stage IB∼IIA cervical cancer. We also explored the influences of HPV infection status on the survival of cervical cancer patients.

Methods: We collected data for 583 women with stage IB∼IIA cervical cancer in Sun Yat-sen University Cancer Center between 2009 and 2017. The t-test, chi-squared (χ²) test and Fisher’s exact test were applied to compare the differences of inflammatory indexes and clinicopathological features between HPV-positive and HPV-negative groups. Univariate and multivariate analyses were used to identify clinicopathological factors that were associated with the prognosis of cervical cancer patients.

Results: There were no differences in overall survival (OS) and progression-free survival (PFS) between HPV-positive and HPV-negative groups. In HPV-positive group, the maximum tumor size, neoadjuvant chemotherapy and the body mass index (BMI) correlated significantly with C-reactive protein/albumin ratio (CAR). The maximum tumor size and the prognostic nutritional index (PNI) correlated significantly with the platelet-lymphocyte ratio (PLR). The maximum tumor size, neoadjuvant chemotherapy and PLR correlated significantly with PNI. Univariate and multivariate analyses showed that the depth of tumor invasion (HR: 3.651, 95% CI: 1.464–9.103, p = 0.005; HR: 2.478, 95% CI: 1.218–5.043, p = 0.012) and CAR (HR: 5.201, 95% CI: 2.080–13.004, p < 0.0001; HR: 2.769, 95% CI: 1.406–5.455, p = 0.003) were independent predictors of poor OS and PFS. PNI was an independent protective factor of OS (HR: 0.341, 95% CI: 0.156–0.745, p = 0.007). PLR was an independent factor of PFS (HR: 1.991, 95% CI: 1.018–3.894, p = 0.044). In HPV-negative group, BMI correlated significantly with CAR. Only depth of invasion (HR: 9.192, 95% CI: 1.016–83.173, p = 0.048) was the independent predictor of poor OS, and no inflammation indexes were independent predictors of prognosis.

Conclusion: In patients with HPV-positive cervical cancer, depth of invasion, PNI and CAR are independent factors of OS, and depth of invasion, PLR and CAR are independent factors for PFS. For patients with HPV-negative disease, no inflammation indexes had predictive value for prognosis. The predictive value of inflammation indexes on prognosis is more significant in patients with HPV-positive cervical cancer. Stratification of HPV infection status promotes a more precise clinical application of inflammation indexes, thus improving their accuracy and feasibility.

Preoperative Prognostic Nutritional Index and Neutrophil-to-Lymphocyte Ratio Predict Survival Outcomes of Patients With Hepatocellular Carcinoma After Curative Resection

Increasing evidence indicates that preoperative prognostic indices can serve as independent predictors of survival in patients with cancer. However, the applicability of these indices in patients with hepatocellular carcinoma (HCC) is controversial. This study aims to investigate the prognostic value of these indices in patients with HCC after curative hepatectomy. We retrospectively analyzed the data of 215 patients who underwent curative resection for HCC. Prognostic indices including prognostic nutritional index (PNI) and neutrophil-to-lymphocyte ratio (NLR) were evaluated by comparing by the area under the curve (AUC). Univariate analysis and multivariate analysis were performed to identify independent prognostic factors. Additionally, risk factors were combined to predict the survival of patients. We found that serum albumin concentration, tumor diameter, tumor stage, degree of differentiation, PNI, and NLR were independent prognostic factors for overall survival (OS). Vascular invasion, tumor stage, degree of differentiation, and PNI were independent prognostic factors for recurrence-free survival (RFS). The cutoff value of the PNI and NLR was 43.75 and 3.29, respectively. Patients with low NLR and high PNI had the best outcomes, potentially indicative of the intensive antitumor effects of the immune system. Moreover, patients with at least three risk factors had a significantly lower OS and RFS compared with those with two or fewer risk factors. This new nomogram based on PNI and NLR may provide an accessible and individualized prediction of survival and recurrence for HCC patients.
