RESUMEN

The primary treatment for glioblastoma (GBM) is removing the tumor mass as defined by magnetic resonance imaging (MRI). However, MRI has limited diagnostic and predictive value. Tumor-associated macrophages (TAMs) are abundant in GBM microenvironment (TME) and are found in peripheral blood (PB). FKBP51 expression, with its canonical and spliced isoforms, is constitutive in immune cells and aberrant in GBM. Spliced FKBP51s supports M2-polarization. To find an immunological signature that combined with MRI could advance in diagnosis, we immunophenotyped the macrophages of TME and PB from 37 GBM patients using FKBP51s and classical M1-M2 markers. We also determined the tumor levels of FKBP51s, PD-L1, and HLA-DR. Tumors expressing FKBP51s showed an increase in various M2 phenotypes and Tregs in PB, indicating immunosuppression. Tumors expressing FKBP51s also activated STAT3 and were associated with reduced survival. Correlative studies with MRI and tumor/macrophages co-cultures allowed to interpret TAMs. Tumor volume correlated with M1 infiltration of TME. Co-cultures with spheroids produced M1 polarization, suggesting that M1 macrophages may infiltrate alongside cancer stem-cells. Co-cultures of adherent cells developed the M2 phenotype CD163/FKBP51s expressing pSTAT6, a transcription factor enabling migration and invasion. In patients with recurrences, increased counts of CD163/FKBP51s monocyte/macrophages in PB correlated with callosal infiltration and was accompanied by a concomitant decrease in TME-infiltrating M1 macrophages. PB PD-L1/FKBP51s connoted necrotic tumors. In conclusion, FKBP51s identifies a GBM subtype that significantly impairs the immune system. Moreover, FKBP51s marks PB macrophages associated with MRI features of glioma malignancy that can aid in patient monitoring.

RESUMEN

BACKGROUND: Tumor deposits (TDs) are emerging as an adverse prognostic factor in colorectal cancers (CRCs). However, TDs are somewhat neglected in the current staging system. It has been proposed either to add the TD count to the number of metastatic lymph nodes or to consider TDs as distant metastases; however, the scientific basis for these proposals seems questionable. This study aimed to investigate a new staging system. METHODS: A total of 243 consecutive patients with stage III CRC who were undergoing curative resection and adjuvant chemotherapy were included. Each substage of stage III TNM was split according to the absence or presence of TDs. Receiver operating characteristic (ROC) curves and bootstrap methods were used to compare the current vs the new competing staging system in terms of oncologic outcome prediction. RESULTS: A high rate of TDs was recorded (124 cases [51%]). TDs were correlated with other adverse prognostic indicators, particularly vascular and perineural invasions, and showed a negative correlation with the number of removed lymph nodes, suggesting a possible multimodal origin. In addition, TDs were confirmed to have a negative impact on oncologic outcome, regardless of their counts. Compared with the current staging system, the new classification displayed higher values at survival ROC analysis, a significantly better stratification of patients, and effective identification of patients at high risk of recurrence. CONCLUSIONS: TDs negatively affect the prognosis in CRCs. A revision of the staging system could be useful to optimize treatments. The proposed new classification is easy to implement and more accurate than the current one. This study was registered online on the ClinicalTrials.gov website under the following identifier: NCT05923450.

RESUMEN

BACKGROUND: Mallory-Weiss syndrome (MWS), representing a linear mucosal laceration at the gastroesophageal junction, is a quite frequent cause of upper gastrointestinal bleeding, usually induced by habitual vomiting. The subsequent cardiac ulceration in this condition is likely due to the concomitance of increased intragastric pressure and inappropriate closure of the gastroesophageal sphincter, collectively inducing ischemic mucosal damage. Usually, MWS is associated with all vomiting conditions, but it has also been described as a complication of prolonged endoscopic procedures or ingested foreign bodies. CASE SUMMARY: We described herein a case of upper gastrointestinal bleeding in a 16-year-old girl with MWS and chronic psychiatric distress, the latter of which deteriorated following her parents' divorce. The patient, who was residing on a small island during the coronavirus disease 2019 pandemic lockdown period, presented with a 2-mo history of habitual vomiting, hematemesis, and a slight depressive mood. Ultimately, a huge intragastric obstructive trichobezoar was detected and discovered to be due to a hidden habit of continuously eating her own hair; this habit had persisted for the past 5 years until a drastic reduction in food intake and corresponding weight loss occurred. The relative isolation in her living status without school attendance had worsened her compulsory habit. The hair agglomeration had reached such enormous dimensions and its firmness was so hard that its potential for endoscopic treatment was judged to be impossible. The patient underwent surgical intervention instead, which culminated in complete removal of the mass. CONCLUSION: According to our knowledge, this is the first-ever described case of MWS due to an excessively large trichobezoar.

RESUMEN

A deficient DNA mismatch repair (MMR) system is identified in a non-negligible part of sporadic colorectal cancers (CRCs), and its prognostic value remains controversial. High tumor mutational burden, along with a poor response to conventional chemotherapy and excellent results from immunotherapy, are the main features of this subset. The aim of this study was to evaluate the predictive value of DNA MMR system status for its best treatment. Four hundred and three CRC patients, operated on from 2014 to 2021 and not treated with immunotherapy, entered this study. Immunohistochemistry and polymerase chain reaction, as appropriate, were used to unequivocally group specimens into microsatellite stable (MSS) and instable (MSI) tumors. The win-ratio approach was utilized to compare composite outcomes. MSI tumors accounted for 12.9% of all series. The right tumor location represented the most important factor related to MSI. The status of the DNA MMR system did not appear to correlate with outcome in early-stage CRCs not requiring adjuvant treatment; in advanced stages undergoing conventional chemotherapy, MSI tumors showed significantly poorer overall and disease-free survival rates and the highest win ratio instead. The determination of DNA MMR status is crucial to recommending correct management. There is clear evidence that instable CRCs needing adjuvant therapy should undergo appropriate treatments.

RESUMEN

Inflammatory pseudotumour-like follicular/fibroblastic dendritic cell sarcoma (IPT-like FDCS) is a rare EBV-associated variant of follicular dendritic cell sarcoma, usually arising in the liver or spleen and characterized by a favourable prognosis. The neoplastic cells show variable follicular dendritic cell or fibroblastic reticular cell differentiation and their immunoprofile is still poorly characterized. We describe a case of splenic IPT-like FDCS with unexpected CD31 expression and provide a concise review of English literature on the topic.

RESUMEN

BACKGROUND: Retroperitoneal liposarcoma (RLPS) is a rare malignant tumor of the connective tissue and usually grows to a large size, undetected. Diagnosis is currently based on collective findings from clinical examinations and computed tomography (CT) and magnetic resonance imaging, the latter of which show a fat density mass and possible surrounding organ involvement. Surgical resection is the main therapeutic strategy. The efficacy and safety of further therapeutic choices, such as chemotherapy and radiotherapy, are still controversial. CASE SUMMARY: A 61-year-old man presented with complaint of a large left inguinal mass that had appeared suddenly, after a slight exertion. Ultrasonography revealed an omental inguinal hernia. During further clinical examination, an enormous palpable abdominal mass, continuing from the left inguinal location, was observed. CT revealed a giant RLPS, with remarkable mass effect and wide visceral dislocation. After multidisciplinary consultation, surgical intervention was performed. Subsequent neoadjuvant chemotherapy and radiotherapy were precluded by the mass' large size and retroperitoneal localization, features typically associated with non-response to these types of treatment. Instead, the patient underwent conservative treatment via radical surgical excision. After 1 year, his clinical condition remained good, with no radiological signs of recurrence. CONCLUSION: Conservative treatment via surgery resulted in a successful outcome for a large RLPS.

RESUMEN

Background: A less-invasive surgery is often required today for many tumors, when oncologic radicality is strictly ensured, both to minimize hospital stay and health costs and to guarantee aesthetical results. Breast surgery for cancer has been radically changed in the last years since conservative interventions are widely performed everywhere. Methods: The authors present 75 cases of early breast cancer, randomly treated with standard quadrantectomy and subcutaneous quadrantectomy; the totally subcutaneous surgical technique implies only a short periareolar skin incision and a complete quadrant resection with skin and subcutaneous layer preservation. Continuous data were analyzed by unpaired Student's t-test. The Chi-square test was used to cumulate categorical variables. The Kaplan-Meyer method and log-rank test were used to compare the overall survival and disease-free survival. Results: No difference was found among the two groups in terms of the type of tumor, overall survival (OS), disease-free survival (DFS), early complications, radicality, and mortality. The only significant differences were both found in the length of hospital stay and in postoperative breast deformity that required further intervention in some cases. Conclusion: In the era of mini-invasive surgery and quality assurance, the authors conclude that subcutaneous quadrantectomy is a safe procedure that allows less health cost and a better aesthetical result.

RESUMEN

Background Coronavirus disease 2019 (COVID-19) can be complicated by interstitial pneumonia, possibly leading to severe acute respiratory failure and death. Because of variable evolution ranging from asymptomatic cases to the need for invasive ventilation, COVID-19 outcomes cannot be precisely predicted on admission. The aim of this study was to provide a simple tool able to predict the outcome of COVID-19 pneumonia on admission to a low-intensity ward in order to better plan management strategies for these patients. Methods The clinical records of 123 eligible patients were reviewed. The following variables were analyzed on admission: chest computed tomography severity score (CTSS), PaO2/FiO2 ratio, lactate dehydrogenase (LDH), neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio, C-reactive protein (CRP), fibrinogen, D-dimer, aspartate aminotransferase (AST), alanine aminotransferase, alkaline phosphatase, and albumin. The main outcome was the intensity of respiratory support (RS). To simplify the statistical analysis, patients were split into two main groups: those requiring no or low/moderate oxygen support (group 1); and those needing subintensive/intensive RS up to mechanical ventilation (group 2). Results The RS intensity was significantly associated with higher CTSS and NLR scores; lower PaO2/FiO2 ratios; and higher serum levels of LDH, CRP, D-dimer, and AST. After multivariate logistic regression and ROC curve analysis, CTSS and LDH were shown to be the best predictors of respiratory function worsening. Conclusions Two easy-to-obtain parameters (CTSS and LDH) were able to reliably predict a worse evolution of COVID-19 pneumonia with values of >7 and >328 U/L, respectively.

RESUMEN

BACKGROUND: Microsatellite instability (MSI) is a predictive biomarker for immune checkpoint inhibitors. The main goal was to investigate the discordance between IHC and PCR/NGS for MSI testing in gastrointestinal cancers. METHODS: Two series were analyzed through IHC for mismatch-repair-system proteins (MMRP) and PCR, with one series of 444 colorectal cancers (CRC) and the other of 176 gastric cancers (GC). All cases with discordant results between IHC and PCR were analyzed by NGS. IHC staining was evaluated as follows: proficient MMR (pMMR), with all MMR positive; deficient MMR (dMMR), with the loss of one heterodimer; and cases with the loss/patchy expression of one MMR (lo-paMMR). Cases with instability in at least two markers by PCR were MSI-high (MSI-H) and with instability in one marker, MSI-low (MSI-L). Cases without instability were evaluated as microsatellite-stable (MSS). RESULTS: In the CRC cohort, 15 out of 444 cases were dMMR and 46 lo-paMMR. Among the 15 dMMR, 13 were MSI-H and 2 MSS. Among the 46 lo-paMMR, 13 were MSI-H and 33 were MSS. In the GC cohort, 13 out of 176 cases were dMMR and 6 cases lo-paMMR. Among the 13 dMMR, 12 were MSI-H and only 1 was MSS. All six lo-paMMR cases were MSS. All NGS results were in agreement with PCR. CONCLUSIONS: In clinical practice, MMR-IHC could be used as a screening test and additional molecular analysis is mandatory exclusively in cases carrying loss/patchy MMR-IHC.

RESUMEN

Despite recent progresses, locally advanced gastric cancer remains a daunting challenge to embrace. Perioperative chemotherapy and D2-gastrectomy depict multimodal treatment of gastric cancer in Europe, shows better results than curative surgery alone in terms of downstaging, micrometastases elimination, and improved long-term survival. Unfortunately, preoperative chemotherapy is useless in about 50% of cases of non-responder patients, in which no effect is registered. Tumor regression grade (TRG) is directly related to chemotherapy effectiveness, but its understanding is achieved only after surgical operation; accordingly, preoperative chemotherapy is given indiscriminately. Conversely, Naples Prognostic Score (NPS), related to patient immune-nutritional status and easily obtained before taking any therapeutic decision, appeared an independent prognostic variable of TRG. NPS was calculated in 59 consecutive surgically treated gastric cancer patients after neoadjuvant FLOT4-based chemotherapy. 42.2% of positive responses were observed: all normal NPS and half mild/moderate NPS showed significant responses to chemotherapy with TRG 1-3; while only 20% of the worst NPS showed some related benefits. Evaluation of NPS in gastric cancer patients undergoing multimodal treatment may be useful both in selecting patients who will benefit from preoperative chemotherapy and for changing immune-nutritional conditions in order to improve patient's reaction against the tumor.

RESUMEN

PURPOSE: Oncological outcome depends not only on tumor behaviour but also on nutritional and immune-inflammatory host status. Data in gastric cancer are limited. The main aim of this study was to prospectively assess Naples prognostic score (NPS) in gastric cancer patients. NPS was also compared with prognostic nutritional index (PNI), controlling nutritional status (CONUT) score and systemic inflammation score (SIS). METHODS: Overall survival (OS) and complication rates of 415 patients undergoing gastric cancer surgery from January 2000 to December 2015 were calculated. Disease-free survival (DFS) rates were assessed in 307 radically resected patients. MaxStat analysis was used to identify the best cut-off values. NPS scores were divided into 3 groups (NPS 0-3). The receiver-operating-characteristic (ROC) curve for censored survival data was used to compare the prognostic performance of scoring systems. RESULTS: NPS positively correlated with current scoring systems (p<0.001) and advanced tumor stages (p<0.001). Patients with elevated NPS scores experienced more postoperative complications (all patients: p=0.003; radically resected patients: p=0.010). NPS1 and NPS2 patients had a higher hazard ratio (HR) than NPS0 patients for OS (NPS1 HR 2.04, NPS2 HR 4.27; p<0.001) and DFS (NPS1 HR 1.70, NPS2 HR 4.98; p<0.001). Among the different scoring systems, only NPS was selected as an independent significant predictor for OS (p=0.024) and DFS (p=0.009). NPS was assigned the best prognostic performance by ROC analysis, equalling TNM staging system, and correctly identified highrisk patients. CONCLUSIONS: NPS is an easy to calculate prognostic score strongly associated with outcome in patients undergoing gastric cancer surgery. KEY WORDS: Gastric cancers, Immune-nutritional and inflammatory host status, Naples prognostic score.

RESUMEN

Neoadjuvant chemotherapy (NAC) of breast cancer (BC) improves outcomes, especially in patients with locally advanced and inflammatory cancer. Further insight into clinic-pathological factors influencing outcomes is essential to define the optimal therapeutic strategy for each category of patients and to predict the response to the treatment. In total, 117 patients with BC were treated with NAC with or without trastuzumab between 2010 and 2015. The histologic response to NAC was defined as a pathological complete response (pCR) when there was no evidence of residual invasive tumor in the breast or axillary lymph nodes. Relapse-free survival (RFS) was estimated using the Kaplan-Meier method and compared using log rank analysis. P-value <0.05 was considered statistically significant. The median age of the 117 patients enrolled in the present study was 52 years (age range, 35-85 years). The overall response rate (complete and partial responses) assessed by radiological and pathological evaluation were 76 and 72%, respectively. pCR was achieved in 35 out of 117 patients (~30%). In total, 6 patients (5%) developed progressive disease during chemotherapy. The RFS was 85 months (SE=3; 95% CI 79-91). The median was not reached and the mean follow-up time was 55 months (median 52 months; range 11-100 months). In this time, 20 patients (17%) experienced tumor recurrence. From the univariate analysis, the pathological response was significantly associated with receptor-based subtype, menopausal status and T-stage. From the multivariate analysis by using linear multiple regression and including receptor- menopausal status and T-stage, the model was not significant (P=0.062). However, by using the multiple logistic regression, and including age, pCR was significantly associated with ER+ HER2neg (P=0.006), T2 (P=0.043) and T3 (P=0.018). T-stage, menopausal status and receptor status are significantly associated with the pathological response in patients with inoperable BC treated with NAC.

RESUMEN

BACKGROUND: Neoangiogenesis has proven to be a relevant pathogenetic mechanism in gastric cancer (GC) and lymphatic spread represents an important well-known prognostic factor. Vascular endothelial growth factor C (VEGF-C) plays a key role in lymphangiogenesis and its blood levels in GC patients are easily measurable. This analysis aimed to investigate the prognostic role of preoperative VEGF-C blood levels. METHODS: VEGF-C serum levels were determined by enzyme-linked immunoadsorbent assay (ELISA) in 186 patients observed at our institution from January 2004 until December 2009 and 82 healthy subjects. Statistical analyses were performed using SPSS 21.0. RESULTS: VEGF-C levels were significantly higher in GC patients (median: 287.4 pg/mL; range, 76.2-865.2 pg/mL) than in the control group (median VEGF-C: 31 pg/mL; range, 12-97 pg/mL). A significant correlation between VEGF-C levels, T, N and tumor stage has been described. The median overall survival (OS) was statistically significantly higher in pts with low serum VEGF-C levels [median: not reached (NR) vs. 26 months; P<0.0001]. Higher preoperative VEGF-C levels correlated also with earlier disease relapse and poor disease-free survival (DFS) (median NR in each subgroup, P=0.005). Furthermore, high VEGF-C levels [hazard ratio (HR) =2.7; P=0.018] and tumor grading (HR =0.44; P=0.007) were independent prognostic factors for OS at multivariate analysis. CONCLUSIONS: Our study showed that increased VEGF-C levels are significantly associated with advanced regional lymph node involvement and poor OS and DFS in pts with resected GC paving the way to a possible application as prognostic factor in the clinical practice.

RESUMEN

BACKGROUND: After surgery for liver tumors, recurrence rates remain high because of residual positive margins or undiagnosed lesions. It has been suggested that detection of hepatic tumors can be obtained with near-infrared fluorescence imaging (FI). Indocyanine green (ICG) has been used with contrasting results. The aims of this study were to explore ICG-FI-guided surgery methodology and to assess its potential applications. MATERIALS AND METHODS: Out of 14 patients with liver tumors, 5 were not operated on, and 9 patients (3 primary and 6 metastatic tumors) underwent surgery. ICG (0.5 mg/kg) was injected intravenously 24 hours before surgery. Fluorescence was investigated prior to resection to detect liver lesions, during hepatic transection to guide surgery, on both cross-section and benchtop to assess surgical margins, and for pathological evaluation. RESULTS: All operations were successful and had a short duration. ICG-FI detected all already known lesions (n = 10), and identified 2 additional small tumors (1 hepatocarcinoma and 1 metastasis, diagnostic improvement = 20%). Two hepatocarcinomas were hyperfluorescent; the remaining one, with a central hypofluorescent area and a hyperfluorescent ring, was indeed a mixed cholangiohepatocarcinoma. All metastatic nodules were hypofluorescent with a hyperfluorescent rim. In all cases, in vivo and ex vivo fluorescence revealed clear liver margins. Postoperative pathological examination greatly benefited of liver fluorescence to assess radicality. CONCLUSION: ICG-FI-guided surgery was shown to be an effective tool to improve both intraoperative staging and radicality in the surgical treatment of primary and metastatic liver tumors.

RESUMEN

BACKGROUND: Indocyanine green (ICG) is a near-infrared fluorescent contrast agent, which preferentially accumulates in cancer tissue. The aim of our study was to investigate the role of fluorescence imaging (FI) with ICG (ICG-FI) for detecting peritoneal carcinomatosis (PC) from colorectal cancer (CRC). METHODS: Four CRC patients with PC scheduled for cytoreductive surgery + hyperthermic intraperitoneal chemotherapy were enrolled in this prospective study. At a median time of 50 min after 0.25 mg/kg ICG injected intravenously, intraoperative ICG-FI using Fluobeam® was performed in vivo and ex vivo on all specimens. The Peritoneal Cancer Index was used to estimate the likelihood of complete cytoreduction. RESULTS: No severe complications were recorded. ICG-FI took a median of 20 min (range 10-30, IQR 15-25). Sixty-nine nodules were harvested. Fifty-two nodules had been diagnosed preoperatively by conventional imaging (n = 30; 43%) or intraoperatively by visual inspection/palpation (n = 22; 32%). With ICG-FI, 47 (90%) nodules were hyperfluorescent, and five hypofluorescent. Intraoperative ICG-FI identified 17 additional hyperfluorescent nodules. On histopathology, 16 were metastatic nodules. Sensitivity increased from 76.9%, with the conventional diagnostic procedures, to 96.9% with ICG-FI. The positive predictive value of ICG-FI was 98.4%, and test accuracy was 95.6%. Diagnostic performance of ICG-FI was significantly better than preoperative (p = 0.027) and intraoperative conventional procedures (p = 0.042). The median PCI score increased from 7 to 10 after ICG-FI (p < 0.001). CONCLUSIONS: Our results suggest that intraoperative ICG-FI can improve outcomes in patients undergoing CS for PC from CRC. Further studies are needed to determine the role of ICG-FI in this patient population.

RESUMEN

BACKGROUND: The prognosis of right colon cancer remains disappointing. Complete mesocolic excision (CME) with central vascular ligation (CVL), based on the same oncological principles of total mesorectal excision, has been speculated to result in a better outcome. To evaluate the oncological adequacy of CME with CVL, we carried out a comparative study with propensity score-matched analysis between two different surgical procedures performed at Italian and Egyptian University cancer centers. METHODS: Forty-six Egyptian patients underwent conventional right hemicolectomy, while eighty-eight Italian patients underwent CME with sharp dissection between the embryological planes, exposure of the superior mesenteric vessels with extended lymphadenectomy, and CVL. RESULTS: All operations were successful with no increase in postoperative complications (10% in the patients undergoing CME vs. 19.5% in Egyptian patients). Number of harvested nodes (21 vs. 13) and lymph node ratio (0.08 vs. 0.22) were significantly different in patients undergoing CME (P=0.0001 and P=0.005, respectively). In these patients, the risk of cancer relapse was reduced to as much as one third (8% vs. 22%), even in node-positive tumors, and locoregional recurrences were never experienced. The classic operation was significantly associated with poor outcome (5-year disease-free survival rates were 89.2% in the group undergoing CME and 49.1% in the classic group, P=0.02). Propensity score-matched analysis warranted optimal balance and confirmed overall results. CONCLUSIONS: Right colon cancer patients undergoing CME benefitted from more oncological adequacy, with no increased postoperative complication rate, a decreased locoregional recurrence rate, and a better long-term outcome than patients operated on with the conventional procedure.

RESUMEN

BACKGROUND: The existing scores reflecting the patient's nutritional and inflammatory status do not include all biomarkers and have been poorly studied in colorectal cancers. OBJECTIVE: The purpose of this study was to assess a new prognostic tool, the Naples prognostic score, comparing it with the prognostic nutritional index, controlling nutritional status score, and systemic inflammation score. DESIGN: This was an analysis of patients undergoing surgery for colorectal cancer. SETTINGS: The study was conducted at a university hospital. PATIENTS: A total of 562 patients who underwent surgery for colorectal cancer in July 2004 through June 2014 and 468 patients undergoing potentially curative surgery were included. MaxStat analysis dichotomized neutrophil:lymphocyte ratio, lymphocyte:monocyte ratio, prognostic nutritional index, and the controlling nutritional status score. The Naples prognostic scores were divided into 3 groups (group 0, 1, and 2). The receiver operating characteristic curve for censored survival data compared the prognostic performance of the scoring systems. MAIN OUTCOME MEASURES: Overall survival and complication rates in all patients, as well as recurrence and disease-free survival rates in radically resected patients, were measured. RESULTS: The Naples prognostic score correlated positively with the other scoring systems (p < 0.001) and worsened with advanced tumor stages (p < 0.001). Patients with the worst Naples prognostic score experienced more postoperative complications (all patients, p = 0.010; radically resected patients, p = 0.026). Compared with group 0, patients in groups 1 and 2 had worse overall (group 1, HR = 2.90; group 2, HR = 8.01; p < 0.001) and disease-free survival rates (group 1, HR = 2.57; group 2, HR = 6.95; p < 0.001). Only the Naples prognostic score was an independent significant predictor of overall (HR = 2.0; p = 0.03) and disease-free survival rates (HR = 2.6; p = 0.01). The receiver operating characteristic curve analysis showed that the Naples prognostic score had the best prognostic performance and discriminatory power for overall (p = 0.02) and disease-free survival (p = 0.04). LIMITATIONS: This is a single-center study, and its validity needs additional external validation. CONCLUSIONS: The Naples prognostic score is a simple tool strongly associated with long-term outcome in patients undergoing surgery for colorectal cancer.

RESUMEN

BACKGROUND: Cancer outcome is considered to result from the interplay of several factors, among which host inflammatory and immune status are deemed to play a significant role. The neutrophil-to-lymphocyte ratio (NLR) and the lymphocyte-to-monocyte ratio (LMR) have been profitably used as surrogate markers of host immunoinflammatory status and have also been shown to correlate with outcome in several human tumors. However, only a few studies on these biomarkers have been performed in gastric cancer patients, yielding conflicting results. METHODS: Data were retrieved from a prospective institutional database. Overall survival (OS) of 401 patients undergoing surgery for gastric cancer between January 2000 and June 2015 as well as disease-free survival (DFS) rates in 297 radically resected patients were calculated. MaxStat analysis was used to select cutoff values for NLR and LMR. RESULTS: NLR and LMR did not significantly correlate with tumor stage. Patients with a high NLR and a low LMR experienced more tumor recurrences (p < 0.001) and had a higher hazard ratio (HR) for both OS (HR = 2.4 and HR = 2.10; p < 0.001) and DFS (HR = 2.99 and HR = 2.46; p < 0.001) than low NLR and high LMR subjects. Both biomarkers were shown to independently predict OS (HR = 1.65, p = 0.016; HR = 2.01, p = 0.002, respectively) and DFS (HR = 3.04, p = 0.019; HR = 4.76, p = 0.002, respectively). A score system combining both biomarkers was found to significantly correlate with long-term results. CONCLUSIONS: A simple prognostic score including preoperative NLR and LMR can be used to easily predict outcome in gastric cancer patients undergoing surgery.
