Prognostic Factor In Stage Research Articles

The primary tumor location in colorectal cancer: A focused review on its impact on surgical management.

The primary tumor location (PTL) has attracted increasing attention in recent years for colorectal cancer (CRC) patients. Although the underlying mechanisms for differences caused by PTL remain still unclear, right-sided colon (RCC) and left-sided colon (LCC) are now considered as distinct entities because of their different molecular profile and clinical response to surgery and chemotherapy. In this article, we review the influence of PTL particularly on surgical management of primary and metastatic CRC settings. For nonmetastatic CRC, RCC could be a slightly superior prognostic factor after curative resection in stage I-II CRC, while RCC could be an inferior prognostic factor in stage III CRC with worse survival after recurrence, suggesting the oncological aggressiveness of recurrent RCC. For metastatic CRC, RCC could be a predictor of worse survival after hepatectomy of liver metastases from CRC with aggressive recurrence pattern and lower chance of re-resection. In lung metastases from CRC, the role of PTL still remains uncertain because of the limited number of studies. As to the impact of PTL on survival outcome after cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy for peritoneal metastases from CRC, a discrepancy exists among studies and further investigation will be needed. The very simple clinical factor of PTL could provide important information for the prediction of the survival outcome after surgery in CRC. Further clinical and basic research will facilitate the clinical application of PTL in a more specified and personalized manner.

The Prognostic Role of Blood Inflammatory Biomarkers and EGFR Mutation Status in Stage IIIA/N2 Non-Small Cell Lung Cancer Patients Treated With Trimodality Therapy.

ObjectivesVarious blood inflammatory biomarkers were associated with treatment response and prognosis of non-small cell lung cancer (NSCLC) in previous studies. In this study, we retrospectively evaluated the prognostic role of pretreatment blood inflammatory biomarkers and epidermal growth factor receptor (EGFR) mutation status in stage IIIA/N2 NSCLC patients with trimodality therapy.MethodsCompletely resected stage IIIA/N2 NSCLC patients with adjuvant chemotherapy and postoperative radiotherapy (PORT) were assessed in this study. Cutoff values of blood inflammatory factors were calculated by the R package SurvivalROC of R software. SPSS Statistics software was used for survival analyses. Kaplan-Meier survival curve and log-rank test were used to compare the survival difference between every two groups. Univariate and multivariate analyses of predictive factors were performed by Cox proportional hazards regression model.ResultsThe univariate analysis showed that T stage (p=0.007), EGFR mutation status (p=0.043), lymphocyte-to-monocyte ratio (LMR) (p=0.067), and systemic immune-inflammation index (SII) (p=0.043) were significant prognostic factors of disease-free survival (DFS). In the multivariate analysis, T2 (HR=0. 885, 95% CI: 0.059-0.583, p=0.004), EGFR mutation-positive (HR=0.108, 95% CI: 0.023-0.498, p=0.004) and elevated pretreatment SII (HR=0.181, 95%CI: 0.046-0.709, p=0.014) were independently related to shorter DFS. High pretreatment neutrophil counts (HR=0.113, p=0.019) and high systemic inflammation response index (SIRI) (HR=0.123, p=0.025) were correlated with worse overall survival (OS) by the univariate analysis. In the multivariate analysis, only high pretreatment SIRI was an independent predictor for poorer OS (HR=0.025, 95% CI: 0.001-0.467, p=0.014).ConclusionsIn conclusion, we identified that high pretreatment SII and SIRI were unfavorable prognostic factors in stage IIIA/N2 NSCLC patients treated with surgery, adjuvant chemotherapy and PORT. Patients with high pretreatment SII, high pretreatment SIRI, T2, and EGFR mutation-positive may need more forceful adjuvant treatment. Further prospective studies with large-scale are needed to validate our results and identify the proper cut-off values and optimum adjuvant treatment for distinct patient population.

Prognostic Value of the Distribution of Lymph Node Metastasis in Locally Advanced Rectal Cancer After Neoadjuvant Chemoradiotherapy

Background: The objective of this study is to assess the prognostic value of lymph node metastasis distribution (LND) in locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (nCRT).Methods: This study included 179 patients with pathological stage III LARC who underwent nCRT followed by radical surgery. LND was classified into three groups: LND1, lymph node metastasis at the mesorectum (140/179, 78.2%); LND2, lymph node metastasis along the inferior mesenteric artery trunk nodes (26/179, 14.5%); LND3, lymph node metastasis at the origin of the IMA (13/179, 7.3%). Clinicopathologic characteristics were analyzed to identify independent prognostic factors.Result: LND showed better stratification for 3-year DFS (LND1 66.8, LND2 50, and LND3 15.4%, P < 0.01) compared to the ypN (3-year DFS: N1 59.9 and N2 60.3%, P = 0.34) and ypTNM (3-year DFS: IIIA 68.6%, IIIB 57.5%, and IIIC 53.5, P = 0.19) staging systems. Similar results were found for 3-year LRFS and DMFS. According to multivariate survival analysis, LND was shown to be an independent prognostic factor for DFS, LRFS, and DMFS in patients with positive lymph nodes (P < 0.01, in all cases).Conclusion: LND is an independent prognostic factor in stage III rectal cancer after nCRT. LND can be used as a supplementary indicator for the ypTNM staging system in patients with LARC after nCRT.

Comparison of Vascular Invasion With Lymph Node Metastasis as a Prognostic Factor in Stage I-III Colon Cancer: An Observational Cohort Study.

Purpose: This study aimed to evaluate the prognostic impact of vascular invasion (VI) in comparison with that of lymph node metastasis (LNM) in non-metastatic colon cancer.Methods: Patients who underwent curative surgery for stage I-III colon cancer were divided into four groups depending on the status of VI and LNM (Group I: VI-/LNM-; Group II: VI+/LNM-; Group III: VI-/LNM+; Group IV: VI+/LNM+). Group III was subdivided according to the nodal (N) stage (Group IIIA: VI-/N1; Group IIIB: VI-/N2). Oncological outcomes were compared between Groups II and III.Results: In total, 793 non-metastatic colon cancer patients were included. Group II [hazard ratio (HR) 2.34, 1.01–5.41] and Group III (HR 1.91, 1.26–2.89) were independently associated with poor disease-free survival (DFS). The 5-year DFS rates were comparable in Groups II (71.6%) and III (72.5%) (P = 0.637). When Group III was subdivided into Groups IIIA and IIIB, DFS deteriorated in the following order: Groups IIIA, II, and IIIB. The 5-year DFS rates were 79.7, 71.6, and 61.4% in Groups IIIA, II, and IIIB, respectively. Group II had a tendency toward early recurrence. The 1- and 2-year DFS rates were 76.3 and 71.6% in Group II and 88.3 and 79.8% in Group III, respectively (P = 0.067 and 0.247). All recurrences in Group II were distant metastases.Conclusion: VI is a prognostic factor as significant as LNM and may be a stronger prognostic factor than N1 stage in non-metastatic colon cancer. Furthermore, a potential association was observed between VI and recurrence patterns, such as early recurrence and distant metastasis.

Evaluation of Traditional Prognostic Factors for Stage I-III Colorectal Cancer Patients Who Survived for Over Five Years After Surgery

The aim of this study was to explore the prognostic factors in stage I-III colorectal cancer (CRC) patients who had survived for over five years. A total of 9754 stage I-III CRC patients who received curative surgery in the Department of Colorectal Surgery, Fudan University Shanghai Cancer Center were enrolled in this study. Of them, 3640 patients had survived for over five years after surgery. Univariate and multivariate Cox regression analyses were performed in the entire cohort and those who had survived for over five years. Compared with patients in the entire cohort, patients who had survived for over five years were more likely to be younger, have less disease of signet ring cell histology, perineural invasion and vascular invasion, more well differentiated tumors and stage I disease. In the entire cohort, increased age, signet ring cell, poor differentiation, more advanced pathological stage, perineural invasion and vascular invasion were inversely associated with disease-free survival (DFS) and overall survival (OS) using multivariable Cox regression analyses. Only age, pathological stage and perineural invasion remained significant in patients who had survived for over five years. Moreover, tumor location was an independent factor for OS in this subgroup. Predictors for prognosis of CRC change over time. Age, pathological stage and perineural invasion deserve more attention among patients who have survived for over five years.

388MO Tumor budding, an important prognostic factor in stage III colon cancer patients treated with oxaliplatin-based chemotherapy

Histological growth characteristics at the invasive front may reflect tumor aggressiveness. Specifically, tumor budding (TB), defined as single cancer cells or cluster comprising less than five cells and representing the dynamic process of epithelial-mesenchymal transition, is listed among prognostic markers in colon cancer (CC). However, its use for a better disease stratification needs to be further explored. Its prognostic role was thus evaluated in a phase III trial investigating 3 vs 6 months of oxaliplatin-based adjuvant treatment in stage III CC patients.

714P Prognostic factors in stage I seminoma: Data from the phase III, randomised TRial of Imaging and Surveillance in Seminoma Testis (TRISST)

Outcomes in stage I seminoma are excellent. 15% relapse when managed with surveillance and survival approaches 100%. Risk stratification would allow management to be tailored, avoiding unnecessary treatment and/or irradiation. However, validated factors based on contemporary data are lacking. The Trial of Imaging and Surveillance in Seminoma Testis (TRISST, ISRCTN65987321) - the largest in this setting - investigated optimal frequency and modality of imaging. Here, trial data are used to determine prognostic factors for relapse.

The Prognostic Role of PORT and EGFR Mutation Status in Completely Resected Stage IIIA/N2 Non-Small Cell Lung Cancer Patients with Postoperative Chemotherapy.

Background: The treatment choice for completely resected stage IIIA/N2 non-small cell lung cancer (NSCLC) patients is still controversial now. Our study aims to identify potential prognostic factors in stage IIIA/N2 NSCLC patients with complete surgical resection and postoperative chemotherapy.Methods: In this study, we screened the stage IIIA/N2 NSCLC patients diagnosed in the Affiliated Cancer Hospital of Zhengzhou University from 2015 to 2019. Completely resected patients with postoperative chemotherapy (PCT) were enrolled. The univariate and multivariate COX proportional hazards regression analyses were used to identify the prognostic factors. The Kaplan-Meier survival curve was used to compare the disease-free survival (DFS) and overall survival (OS) in the subgroup analyses.Results: 180 patients were collected, including 142 patients with PCT treatment alone and 38 patients with postoperative radiotherapy (PORT) treatment. The median DFS was 17.8 months (95% CI: 16.5–19.1 months) and the median OS was 50.6 months (47.4–53.9 months) in all the patients. The median DFS of the PORT group was significantly longer than the PCT group (38.7 vs 16.7 months, p < 0.001). Epidermal growth factor receptor (EGFR) mutation-positive patients had a worse DFS compared with EGFR mutation-negative patients (16.8 vs 18.0 months, p = 0.032). Possible prognostic factors were evaluated through univariate COX regression analysis. The further multivariate COX regression analysis showed that patients with PORT (HR: 0.318, 95% CI: 0.185–0.547, p < 0.001), EGFR mutation-negative (HR: 0.678, 95% CI: 0.492–0.990, p = 0.044), T1 (HR: 0.661, 95% CI: 0.472–0.925, p = 0.016), and lobectomy (HR: 0.423, 95% CI: 0.191–0.935, p = 0.034), had better DFS. The only independent prognostic factor of OS was the type of surgery (p = 0.013).Conclusion: PORT might improve the DFS of stage IIIA/N2 NSCLC patients with complete surgical resection and PCT, but it cannot increase OS. Besides, EGFR mutation status, T stage, and type of surgery are possible independent prognostic factors for DFS, and type of surgery is associated with OS. These factors remain to be clarified in further studies.

Preoperative Lymphocyte-to-Monocyte Ratio in the Prognostication of Advanced Resectable Colon Cancer: a Retrospective Observational Study

Lymphocyte-to-monocyte ratio (LMR) has been reported as a biomarker for predicting the prognosis of colorectal cancer. However, the clinical usefulness of LMR requires detailed research, which can contribute to better therapeutic strategies. A cohort of 554 patients with resectable advanced colon cancer in our institution was analyzed retrospectively. An analysis of stages II and III resectable advanced colon cancer was performed. LMR was useful for predicting overall survival (OS) and relapse-free survival (RFS). The ROC curve revealed an LMR value of 2.77 as a cutoff for OS. A high LMR was an independent prognostic factor and was associated with a high hazard ratio (HR) in all cases for OS (HR = 0.530, 95% confidence interval (CI) = 0.334–0.842, p = 0.007). A high LMR was not an independent prognostic factor in stage II cases but was a predictor with the strongest association with prognosis in patients with stage III cases for OS (HR = 0.383, 95% CI = 0.160–0.915, p = 0.031). LMR is a strong predictor of prognosis in patients with stage III colon cancer and may be useful in postoperative treatment options.

Prognostic Implications of Chemotherapy-Induced Neutropenia in Stage III Colorectal Cancer

Previous studies have reported chemotherapy-induced neutropenia (CIN) as a prognostic factor in stage IV colorectal cancer (CRC). However, only few reports analyzed the prognostic value of CIN in patients with stage III CRC who received adjuvant chemotherapy with oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX). We aimed to investigate the prognostic implications of CIN in patients with stage III CRC who received adjuvant chemotherapy with FOLFOX. We retrospectively analyzed patients with stage III CRC who received adjuvant chemotherapy with FOLFOX at a tertiary hospital between January 2007 and December 2017. Severe CIN was defined as an absolute neutrophil count of less than 1000/mm3. Three-y disease-free survival (DFS) and overall survival (OS) were analyzed as primary endpoints. Among the 199 patients included in this study, 110 patients (55.3%) experienced severe CIN. There were no significant differences in survival outcomes between the control and CIN groups (control group versus CIN group: 3-y OS, 82.0 % versus 72.7 %; log rank, P=0.250 and 3-y DFS, 71.9 % versus 62.7; log rank, P=0.294). Univariate and multivariate analyses revealed that CIN did not affect DFS and OS in patients with stage III CRC who received adjuvant FOLFOX chemotherapy. Severe CIN occurring during adjuvant FOLFOX chemotherapy did not play a significant role in the prognosis of patients with stage III CRC.

P-127 Lymphocyte to monocyte ratio as a prognostic factor in stage IV pancreatic ductal adenocarcinoma naive patients before gemcitabine-nab-paclitaxel chemotherapy

The prognostic role of inflammation parameters have long been evaluated in several histological types of tumor. The most studied were the neutrophil to lymphocyte ratio (NLR), the platelet to lymphocyte ratio (PLR), and lymphocyte to monocyte ratio (LMR). In the case of pancreatic ductal adenocarcinoma, the literature described a significant correlation between LMR and outcomes, especially in patients with resectable disease (disease free survival, DFS and overall survival, OS). The aim of our study was to identify a cut off for this index with a prognostic value in patients with stage IV disease and subsequently treated with a gemcitabine plus nab-paclitaxel schedule.

The association between molecular type and prognosis of patients with stage IV breast cancer: an observational study based on SEER database.

Molecular subtype, the basis for personalized treatment of breast cancer, is of great value in evaluating prognosis and guiding treatment of early-stage breast cancer. However, its value in stage IV patients remains unclear. In this study, we investigated the association between molecular subtype and prognosis of de novo stage IV breast cancer using Surveillance, Epidemiology, and End Results (SEER) database with the purpose to provide evidence for optimal therapeutic options for breast cancer patients. We retrospectively analyzed de novo stage IV breast cancer patients with the SEER Program data from 2010 to 2015. Characteristics of patients with different molecular subtypes were compared by chi-square test and survival curves for breast cancer specific survival (BCSS) according to subtypes were plotted by Kaplan-Meier method. The Cox proportional hazards model was performed to search for independent prognostic factors in stage IV breast cancer patients. A total of 11,974 patients were included in this study, among which 7,100 (59.30%) patients were of HR+/HER2-, 2,093 (17.48%) of HR+/HER2+, 1,139 (9.51%) of HR-/HER2+ and 1,642 (13.71%) of HR-/HER2-. Multivariate Cox analysis revealed that molecular subtype, age, race, marital status, grade, surgery and chemotherapy were independent prognostic factors for BCSS in de novo stage IV patients. Taking HR+/HER2- patients as reference, HR+/HER2+ patients had better BCSS (HR =0.81, 95% CI: 0.75-0.88, P<0.001), HR-/ HER2- patients had worse BCSS (HR =1.42, 95% CI: 1.29-1.46, P<0.001) and HR-/HER2+ patients had no significant difference (HR =1.03, 95% CI: 0.98-1.08, P=0.188). In patients with different single organ metastases, the prognosis of HR+/HER2+ subtype was the best (except brain metastasis), while that of HR-/HER2- subtype was the worst. Molecular subtypes were closely associated with the prognosis of de novo stage IV breast cancer. Among the four subtypes, HR+/HER2+ patients had the best prognosis while HR-/HER2- patients had the worst. The prognosis of patients with different single organ metastases was the same, but in patients with brain metastases, HR+/HER2+ ones did not have a significantly better prognosis than other subtypes except triple-negative type.

High expression of microRNA-126 relates to favorable prognosis for colon cancer patients

miR-126 has been identified both as a tumor suppressor and an oncogene in different types of cancer. The aim of this study was to investigate the prognostic impact of miR-126-expression in colon cancer patients. Tumor tissue from 452 patients operated for stage I–III colon cancer was retrospectively collected and tissue microarrays were constructed. miR-126 expression was evaluated by in situ hybridization and analyzed using digital pathology. To isolate the compartment specific contribution of miR-126, tumor and adjacent tumor stroma were considered separately. In univariate analyses, high expression of miR-126 in tumor and stroma was related to increased disease-specific survival (p < 0.001 and p = 0.005, respectively). In multivariate analyses, high miR-126 expression in tumor remained a significant independent predictor of improved disease-specific survival (HR = 0.42, CI 0.23–0.75, p = 0.004). Within different TNM-stages there was a tendency towards the same results, but with statistically significant results in stage II only (p = 0.007). High expression of miR-126 is an independent positive prognostic factor in stage I–III colon cancer. This finding may be used to identify patients in need of adjuvant chemotherapy.

Impact of Inferior Mesenteric Artery Lymph Node Metastasis on the Prognosis of Left-sided Colorectal Cancer.

This study aimed to investigate the impact of the inferior mesenteric artery (IMA) lymph node metastasis [IMALN (+)] on prognosis in left-sided colorectal cancer (LCRC). A total of 285 patients with stage III LCRC and 118 patients with stage IV LCRC who underwent resection of primary tumor between 2005 and 2016 were included. IMALN (+) patients (n=10) had worse overall survival (OS) than patients without IMA lymph node metastasis [IMALN (-); n=275] in stage III LCRC (p=0.007). Multivariate analysis revealed that IMALN (+) was a prognostic factor in stage III LCRC (OS, HR=3.09, p=0.043). Conversely, there was no difference between the OS of IMALN (+) and stage IV LCRC with distant lymph node metastasis only [stage IV LCRC (LYM); n=21; p=0.434]. The prognosis of IMALN (+) was worse than that of IMALN (-); it was similar to that of stage IV LCRC (LYM).

Znaczenie kliniczne umiejscowienia ogniska pierwotnego raka jelita grubego

Rak jelita grubego jest jednym z najczęściej występujących nowotworów złośliwych na świecie. Heterogenny przebieg choroby oraz różnice genetyczne i molekularne pomiędzy guzami występującymi w różnych odcinkach jelita grubego przyczyniły się do próby oceny znaczenia umiejscowienia ogniska pierwotnego nowotworu oraz podziału tego nowotworu na raka jelita grubego z prawostronną lub lewostronną lokalizacją ogniska pierwotnego. Wyniki retrospektywnych analiz badań III fazy wskazują, iż prawostronna lokalizacja nowotworu jest negatywnym czynnikiem rokowniczym w IV i III stopniu zaawansowania choroby. Korzyść z dodania przeciwciała anty-EGFR do I linii chemioterapii paliatywnej wykazano dla chorych z guzem pierwotnym zlokalizowanym po stronie lewej, a efekt leczenia wydaje się być lepszy niż terapia anty-VEGF połączona z cytostatykami. Wyniki leczenia pacjentów z prawostronną lokalizacją guza pierwotnego są gorsze niezależnie od rodzaju zastosowanego leczenia. U chorych z prawostronną lokalizacją nowotworu wydaje się, iż leczenie bewacyzumabem przynosi większą korzyść w porównaniu z terapią anty-EGFR, choć powyższe wnioski wyciągane są na podstawie analiz mniej licznych grup chorych. Skuteczność leczenia bewacyzumabem jest niezależna od lokalizacji ogniska pierwotnego nowotworu. Nie jest pewne, czy pierwotne umiejscowienie nowotworu należy uznać za samodzielny czynnik prognostyczny lub predykcyjny, czy też powinno się poszukiwać specyficznych zaburzeń genetycznych i molekularnych odpowiadających za wykazane i potencjalne różnice.

GRP75-mediated upregulation of HMGA1 stimulates stage I lung adenocarcinoma progression by activating JNK/c-JUN signaling.

BackgroundRecurrence is a major challenge in early‐stage lung adenocarcinoma (LUAD) treatment. Here, we investigated the role and mechanism of high‐mobility group AT‐hook 1 (HMGA1) and glucose‐regulated protein 75‐kDa (GRP75) in stage I LUAD and evaluated their potential as biomarkers for predicting the recurrence and prognosis of stage I LUAD.MethodsThe TCGA dataset was used to investigate the clinical significance of HMGA1 and GRP75 in early‐stage LUAD. The biological functions of HMGA1 and GRP75 in LUAD were investigated both in vitro and in vivo through overexpression and knockdown experiments. The interaction and regulation between HMGA1 and GRP75 were evaluated with coimmunoprecipitation and ubiquitination assays. The downstream signaling pathway of the GRP75/HMGA1 axis was investigated by mRNA‐sequencing analysis.ResultsBoth HMGA1 expression levels and GRP75 expression levels were associated with recurrence in stage I LUAD patients. In particular, HMGA1 had potential as an independent prognostic factor in stage I LUAD patients. Overexpression of GRP75 or HMGA1 significantly stimulated LUAD cell growth and metastasis, while silencing GRP75 or HMGA1 inhibited LUAD cell growth and metastasis in vitro and in vivo. Importantly, GRP75 inhibited ubiquitination‐mediated HMGA1 degradation by directly binding to HMGA1, thereby causes HMGA1 upregulation in LUAD. In addition, the GRP75/HMGA1 axis played its role by activating JNK/c‐JUN signaling in LUAD.ConclusionsThe activation of GRP75/HMGA1/JNK/c‐JUN signaling is an important mechanism that promotes the progression of stage I LUAD, and a high level of HMGA1 is a novel biomarker for predicting recurrence and a poor prognosis in stage I LUAD patients.

Lymphatic permeation and vascular invasion should not be integrated as lymphovascular invasion in lung adenocarcinoma.

Lymphatic permeation (LY) and vascular invasion (VI) are well-known as postoperative prognostic factors in non-small cell lung cancer (NSCLC). Some reports use the term "lymphovascular invasion (LVI)" in reference to the integration of LY and VI. The purpose in this study is to elucidate whether NSCLC with LY or VI can be labeled as LVI-positive NSCLC or it should be treated as an LY- or VI-positive tumor, respectively. We reviewed 601 completely resected lung adenocarcinomas and squamous cell carcinomas, and examined the respective prognostic and biological significance of LY and VI. Among 454 adenocarcinomas, multivariate survival analyses showed that LY and VI were unfavorable prognostic factors in stages II and III and stages I and II, respectively. Conversely, this relationship was not found among 147 squamous cell carcinomas. Patients with adenocarcinomas with LY and VI had a significantly worse prognosis than those with adenocarcinomas with LY or VI in stage II, but not in stage I. Among 149 recurrent adenocarcinomas, only VI had a strong effect on early recurrence and shorter post-recurrence survival. LY and VI were predictors for multiple organ recurrence of adenocarcinoma. The recurrence of adenocarcinoma with LY was high in the ipsilateral mediastinal lymph nodes, whereas VI was significantly correlated with distant metastasis to organs, such as the brain, liver, and adrenal gland. LY and VI have differing effects postoperative prognosis and recurrence-relevant events, suggesting that these pathological findings should not be integrated as LVI.

Novel Optical Coherence Tomography Parameters as Prognostic Factors for Stage 3 Epiretinal Membranes.

Purpose We aimed to describe the visual prognosis of eyes with ectopic inner foveal layers (EIFLs) after epiretinal membrane (ERM) surgery. Methods This retrospective study enrolled patients diagnosed with stage 3 ERM based on the EIFL staging scheme who underwent ERM surgery with a minimum follow-up period of 12 months. Central foveal thickness (CFT), EIFL thickness, and the length of the ellipsoid zone defect were evaluated at baseline and at 1 month, 6 months, and 12 months after surgery based on pre- and postoperative swept-source optical coherence tomography (OCT) images. The association of EIFL thickness and other OCT parameters with pre- and postoperative best-corrected visual acuity (BCVA) was analyzed. Results Sixty-nine eyes with stage 3 ERMs were analyzed. Preoperative BCVA was correlated with preoperative CFT (r = 0.517, p < 0.001) and preoperative EIFL thickness (r = 0.652, p < 0.001). At 12 months, postoperative BCVA was correlated negatively with preoperative CFT (r = 0.470, p=0.016) and preoperative EIFL thickness (r = 0.582, p=0.004). The improvement in BCVA was not associated with postoperative reduction in CFT (p=0.06), although it was significantly associated with postoperative reduction in EIFL thickness (r = 0.635, p=0.007). Conclusions EIFL thickness should be considered a negative prognostic factor for postoperative anatomical and functional recovery in patients with stage 3 ERMs.

Postoperative, but not preoperative, inflammation-based prognostic markers are prognostic factors in stage III colorectal cancer patients

BackgroundRecent evidence suggests that both preoperative and postoperative inflammation-based prognostic markers are useful for predicting the survival of colorectal cancer (CRC) patients. However, associations between longitudinal changes in inflammation-based prognostic markers and prognosis are controversial.MethodsThe subjects of this study were 568 patients with stage III CRC between 2008 and 2014. Preoperative and postoperative neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), C-reactive protein/albumin ratio (CAR) and lymphocyte-to-C-reactive protein ratio (LCR) were calculated to assess the inflammatory state of subjects. Subjects were stratified into three groups for each marker: preoperatively low inflammatory state (normal group), preoperatively high but postoperatively low inflammatory state (normalised group) and persistently high inflammatory state (elevated group). Multivariable analyses for overall survival (OS) and recurrence-free survival (RFS) were performed to adjust for well-established clinicopathologic factors.ResultsFor all assessed markers, the normalised group had a significantly better prognosis than the elevated group and a similar prognosis as the normal group for both OS and RFS.ConclusionsPostoperative, but not preoperative, inflammation-based prognostic markers more accurately predict OS and RFS in patients with stage III CRC.

Significance of Neutrophil-Lymphocyte Ratio (NLR) as a Prognostic Factor in Stage II Colorectal Cancer

Objective The purpose of this study was to determine the prognostic significance of preoperative neutrophil-lymphocyte ratio for disease-free survival and overall survival in patients with stage II colorectal cancer. Summary of Background Data Previous reports have indicated an association between neutrophil-lymphocyte ratio and poor prognosis and tumor progression in patients with colorectal cancer. However, the role of neutrophil-lymphocyte ratio as a prognostic marker specifically in patients with stage II colorectal cancer has not been well studied. Methods A total of 124 patients with colorectal cancer were included in this study. The disease-free survival and overall survival of patients were compared using preoperative neutrophil-lymphocyte ratio. Univariate and multivariate analyses using the Cox proportional-hazards model were performed to determine the prognostic significance of neutrophil-lymphocyte ratio. Results The overall survival and disease-free survival rates of patients with a neutrophil-lymphocyte ratio ≥ 4.0 were significantly lower than those of patients with a neutrophil-lymphocyte ratio &amp;lt; 4.0. Multivariate analysis showed that a neutrophil-lymphocyte ratio ≥ 4.0, performance status ≥ 1, and depth of tumor invasion (T4) were independent prognostic factors for disease-free survival, whereas age &amp;gt; 80 years, a neutrophil-lymphocyte ratio ≥ 4.0, and performance status ≥ 1 were independent prognostic factors for overall survival. Conclusion Neutrophil-lymphocyte ratio is an independent poor prognostic factor in patients with stage II colorectal cancer undergoing curative resection.
