Predictive and prognostic value of prognostic nutritional index for locally advanced breast cancer.

ABSTRACT: Background:The prognostic nutritional index (PNI) is an indicator of nutritional immune status. Recently, the PNI has been found to be significantly associated with the clinical outcome of various solid tumors. Few patients with newly diagnosed breast cancer are in a state of malnutrition. In contrast, breast cancer is usually an overnutrition-related disease. This study aimed to explore the relationship of an excessively high PNI with sensitivity to neoadjuvant therapy and the prognosis of patients with locally advanced breast cancer. Methods:A total of 202 patients from two clinical trials, SHPD002 and SHPD003, were included. Binary logistic regression analysis was used to assess the association between the PNI and pathological complete response (pCR). Univariate and multivariate survival analyses were performed to assess the prognostic factors used to predict disease-free survival (DFS). Results:An excessively high PNI was more difficult to achieve pCR (OR =0.322; 95% CI, 0.132-0.788, P=0.013) and was associated with a worse DFS (log-rank P=0.013). The PNI was an independent prognostic factor for DFS in all patients (HR =3.027; 95% CI, 1.207-7.592, P=0.018), the premenopausal (HR =8.292; 95% CI, 1.670-41.17, P=0.010), clinical T3 and T4 (HR =3.405; 95% CI, 1.141-10.16, P=0.028), ER negative (HR =9.698; 95% CI, 1.205-78.07, P=0.033), HER2 negative (HR =3.765; 95% CI, 1.101-12.88, P=0.035) and pCR subgroups (HR =11.912; 95% CI, 1.326-107.0, P=0.027). Conclusions:An excessively high PNI was a risk factor for sensitivity to neoadjuvant therapy and prognosis of patients with locally advanced breast cancer.

Project description:BackgroundSarcopenia is associated with poor clinical outcomes in patients with locally advanced gastric cancer (LAGC). Currently, the diagnostic criteria for sarcopenia are complex and laborious. Increased evidence suggests the inflammatory state of the body is closely associated with the development of sarcopenia. The systemic immune-inflammatory index (SII) and the prognostic nutritional index (PNI) are representative blood indicators of the status of the systemic inflammatory response, but the clinical significance of the combined testing of these two indicators remains unclear. We aimed to develop a simple and practical risk score (SII-PNI score) to screen patients with LAGC for sarcopenia on admission for early diagnosis.MethodsWe registered a prospective clinical study from January 2011 to May 2016 involving 134 patients with LAGC undergoing radical surgical resection. All patients followed the definition of sarcopenia in the Asian Working Group on Sarcopenia (AWGS) guidelines and were divided into sarcopenia and non-sarcopenia groups. SII-PNI score 0-2 was scored as 2 for high SII (≥432.9) and low PNI ( ≤ 49.5); score 1, either high SII or low PNI; score 0, no high SII or low PNI.ResultsAll patients underwent radical surgery, including 31 patients (23.13%) with sarcopenia according to AWGS criteria. The SII-PNI score was significantly lower in the non-sarcopenic patients than in the sarcopenic patients (p < 0.001). Logistic multivariate analysis showed that the SII-PNI score predicted an independent prognostic factor for sarcopenia (p < 0.001). Patients with high SII-PNI scores had significantly worse prognosis than those with low SII-PNI scores (p < 0.001). The SII-PNI score was an independent prognostic factor for predicting overall survival and disease-free survival (p = 0.016, 0.023).ConclusionPeripheral blood parameters SII-PNI scores accurately identify sarcopenia in patients with LAGC and could be used as potential systemic markers.

Project description:BackgroundWe examined the predictive value of mismatch repair (MMR) status in relation to responses to neoadjuvant therapy and the prognosis of locally advanced rectal cancer patients.MethodsA total of 854 consecutive patients with locally advanced rectal cancer with MMR status who underwent neoadjuvant therapy followed by curative surgery between January 2013 and December 2018 were included this retrospective study. MMR status was determined by an analysis of MMR protein expression by immunohistochemistry (IHC). Propensity score matching was performed to reduce imbalances in baseline characteristics. The categorical variables were compared using the Chi-square test or Fisher's exact test. Local recurrence-free survival (LRFS) and disease-free survival (DFS) curves were estimated using the Kaplan-Meier method.ResultsDeficient MMR (dMMR) was detected in 63 of the 854 (7.4%) patients. Patients with dMMR had a lower proportion of tumor regression grade (TRG) of 0-1 compared with proficient MMR (pMMR) (28.6% vs. 43.7%; P=0.027). After propensity score matching at 1:4 for patients who received chemotherapy alone, proportion of TRG of 0-1 was observed to be significantly lower in dMMR than pMMR patients (9.1 vs. 30.3%%; P=0.013). For patients who received chemoradiation, after matching, no significant difference in the proportion of TRG 0-1 and the pathological complete response (pCR) rate was observed. The multivariable analysis revealed that patients whose tumors had dMMR had significantly longer DFS than those whose tumors had pMMR [hazards ratio (HR) =0.38, 95% confidence interval (CI): 0.18-0.81, P=0.013]. In the subgroup analysis, dMMR was only a statistically significant prognostic factor for DFS in patients with ypStage II/III (HR =0.38, 95% CI: 0.17-0.86; P=0.020).ConclusionsWe found that patients with dMMR responded worse to chemotherapy alone than patients with pMMR, in terms of TRG. Also, dMMR is a good prognostic marker for DFS in patients with ypStage II/III after neoadjuvant therapy.

Project description:BackgroundTo construct an effective prognostic index to predict overall survival (OS) and triplet regimen efficacy for advanced gastric cancer (AGC) patients treated with platinum-based and fluorouracil-based chemotherapy.ObjectivesBetween 2011 and 2021, 679 patients from two randomized phase III trials and one phase II trial were enrolled.DesignsWe collected 11 baseline clinicopathological and 14 hematological parameters to establish a prognostic index.MethodsUnivariate and multivariate Cox analyses were used to screen prognostic factors, and a prognostic index nomogram was conducted.ResultsSeven prognostic factors were identified: primary tumor site in the non-proximal gastric area, signet-ring cell carcinoma (SRCC)/mucinous carcinoma, peritoneal metastasis, neutrophil count higher than the upper limit of normal value (ULN), lymphocyte count lower than the lower limit of normal value, lactate dehydrogenase level higher than the ULN, and alkaline phosphatase level higher than the ULN as significant for prognosis. A prognostic nomogram named the Fudan advanced gastric cancer prognostic risk score (FARS) index was constructed, and patients in the high-risk group had significantly shorter OS than those in the low-risk group (median OS, 15.5 versus 8.0 months, p < 0.001). The areas under the curve of the FARS index for 1-, 2-, and 3-year OS were 0.70, 0.72, and 0.77, respectively. A validation and external cohort verified the prognostic value of the FARS index. Moreover, three triplet regimen efficacy parameters were identified: SRCC/mucinous adenocarcinoma, primary tumor location in the non-proximal gastric area, and peripheral neutrophil count higher than the ULN; a TRIS index was subsequently conducted. In patients with any two of the three parameters, the triplet regimen showed significantly longer OS than the doublet regimen (p = 0.018).ConclusionThe constructed FARS index to predict the OS of AGC patients and the TRIS index to screen out the dominant population for triplet regimens can be used to aid clinical decision-making and individual risk stratification.

Project description:BackgroundThe efficacy of neoadjuvant chemotherapy is closely related to the long-term prognosis of colorectal cancer (CRC) patients. Apparent diffusion coefficient (ADC) is an index in dynamic enhanced magnetic resonance imaging (MRI), reflecting the density of tumor cells. ADC has been shown to be related to the efficacy of neoadjuvant chemotherapy in other malignant tumors, but there is still a lack of relevant research in CRC patients.MethodsA total of 128 patients with CRC treated with neoadjuvant chemotherapy in The First Affiliated Hospital of Xiamen University from January 2016 to January 2017 were retrospectively collected. According to the response after neoadjuvant chemotherapy, the patients were divided into an objective response group (n=80) and a control group (n=48). The clinical characteristics and ADC levels of the two groups were compared, and the predictive value of ADC on the efficacy of neoadjuvant chemotherapy was analyzed. The patients were followed up for 5 years to observe the difference of survival rate between the two groups, and further analyzed the correlation between ADC and survival rate.ResultsCompared with the control group, the tumor size in the objective response group was significantly reduced (3.32±1.60 vs. 5.07±2.19 cm, P=0.000); ADC significantly increased (1.23±0.18 vs. 0.98±0.18 ×10-3 mm2/s, P=0.000); albumin significantly increased (39.32±4.14 vs. 37.46±4.18 g/L, P=0.016); the proportion of patients with poorly differentiated or undifferentiated tumor cells was significantly lower (51.25% vs. 72.92%, P=0.016); and the 5-year mortality decreased significantly (40.00% vs. 58.33%, P=0.044). ADC had the highest predictive value of objective response for locally advanced CRC patients after neoadjuvant chemotherapy, and the area under the curve (AUC) was 0.834 [95% confidence interval (CI): 0.765-0.903, P=0.000]; ADC had certain predictive value for the 5-year survival of locally advanced CRC patients, and the AUC was 0.778 (95% CI: 0.696-0.861, P=0.000). ADC >1.055×10-3 mm2/s, tumor size <4.1 cm, and moderately or well differentiated tumors were favorable factors for patients with locally advanced CRC to obtain objective response after neoadjuvant chemotherapy (P<0.05).ConclusionsADC could be used as a predictor of the efficacy of neoadjuvant chemotherapy in locally advanced CRC patients.
