Independent Prognostic Factor For Disease-free Survival Research Articles

Clinicopathological Characteristics and Prognosis of HER2-Low Early-Stage Breast Cancer: A Single-Institution Experience.

BackgroundHuman epidermal growth factor 2 (HER2)-low breast cancer, which is defined as HER2 1+ or 2+ in immunohistochemistry without gene amplification, accounts for a considerable part of all breast cancers. However, it remains controversial whether HER2-low breast cancer is a distinct entity. Our aim was to compare the clinicopathological features and survival outcomes between HER2-zero and HER2-low early breast cancer.MethodsThe study was a retrospective analysis that enrolled 1,039 patients with available HER2 expression data in a single institute from 2013 to 2014, of whom 262 HER2-positive patients were excluded from the subsequent analysis. The remaining patients were divided into HER2-zero and HER2-low groups. Each group was further categorized into a hormone receptor (HR)-positive and an HR-negative subgroup. Clinicopathological characteristics were collected and compared between HER2-zero and HER2-low groups. The primary endpoint was disease-free survival (DFS) and overall survival (OS), which were analyzed using the Kaplan–Meier method with log-rank test, landmark analysis, and Cox proportional hazards model.ResultsA total of 777 non-HER2-positive patients were included in this analysis, of whom 126, 552, 53, and 46 patients were HR-positive/HER2-zero, HR-positive/HER2-low, HR-negative/HER2-zero, and HR-negative/HER2-low, respectively. No significant difference in DFS and OS was detected between the HER2-zero group and the HER2-low group when paired by HR status. Landmark analysis with a time point set at 5 years indicated that HR-positive/HER2-low patients had a better DFS compared with HR-positive/HER2-zero patients after 5 years (p = 0.0047). HER2-low status was an independent prognostic factor for DFS after 5 years [hazard ratio (HR) 0.31, 95% confidence interval (CI) 0.13–0.75, p = 0.01].ConclusionThe clinicopathological characteristics and prognosis of HER2-zero and HER2-low breast cancer were similar regardless of HR status. Patients with HR-positive/HER2-low tumors tended to have a better DFS than their HR-positive/HER2-zero counterparts after 5 years.

Prognostic Value of Radiological Extranodal Extension Detected by Computed Tomography for Predicting Outcomes in Patients With Locally Advanced Head and Neck Squamous Cell Cancer Treated With Radical Concurrent Chemoradiotherapy.

ObjectiveExtra Nodal Extension (ENE) assessment in locally advanced head and neck cancers (LAHNCC) treated with concurrent chemo radiotherapy (CCRT) is challenging and hence the American Joint Committee on Cancer (AJCC) N staging. We hypothesized that radiology-based ENE (rENE) may directly impact outcomes in LAHNSCC treated with radical CCRT.Materials and MethodsOpen-label, investigator-initiated, randomized controlled trial (RCT) (2012–2018), which included LAHNSCC planned for CCRT. Patients were randomized 1:1 to radical radiotherapy (66–70 grays) with concurrent weekly cisplatin (30 mg/m2) [cisplatin radiation arm (CRT)] or same schedule of CRT with weekly nimotuzumab (200 mg) [nimotuzumab plus CRT (NCRT)]. A total of 536 patients were accrued and 182 were excluded due to the non-availability of Digital Imaging and Communications in Medicine (DICOM) computed tomography (CT) data. A total of 354 patients were analyzed for rENE. Metastatic nodes were evaluated based on five criteria and further classified as rENE as positive/negative based on three-criteria capsule irregularity with fat stranding, fat invasion, and muscle/vessel invasion. We evaluated the association of rENE and disease-free survival (DFS), loco-regional recurrence-free survival (LRRFS), and overall survival (OS).ResultsA total of 244 (68.9%) patients had radiologically metastatic nodes (rN), out of which 140 (57.3%) had rENE. Distribution of rENE was balanced in the two study groups CRT or NCRT (p-value 0.412). The median follow-up period was 39 months (ranging from 35.5 to 42.8 months). Complete response (CR) was seen in 204 (57.6%); incomplete response (IR), i.e., partial response plus stable disease (PR + SD), in 126 (35.6%); and progressive disease (PD) in 24 (6.8%). rENE-positive group had poor survival compared to rENE-negative group 3-year OS (46.7% vs. 63.6%), poor DFS (48.8% vs. 87%), and LRRFS (39.9% vs. 60.4%). rENE positive had 1.71 times increased risk of IR than rENE negative. Overall stage, site, clinical metastatic node (cN), response, and rENE were the significant factors for predicting OS, DFS, and LRRFS on univariate analysis. After making adjustment on multivariate analysis, rENE was an independent prognostic factor for DFS and trending to be significant for OS.ConclusionPre-treatment rENE is an independent prognostic marker for survival in patients with LAHNSCC treated radically with CCRT that can be used as a potential predictive marker for response to treatment and hence stratify patients into responders vs. non-responders. We propose the mahajan rENE grading system applicable on CT, magnetic resonance imaging, positron emission tomography–contrast-enhanced CT, and ultrasound.

A real-world comparison between neoadjuvant chemoimmunotherapy and chemotherapy alone for resectable non-small cell lung cancer.

The impact of neoadjuvant chemoimmunotherapy on pulmonary resection and related outcomes had been poorly reported in previous studies. The present study aims to clarify the efficacy and safety of neoadjuvant chemoimmunotherapy, and intraoperative difficulty in the following surgery, in comparison with chemotherapy alone in non-small cell lung cancer (NSCLC). Patients with newly diagnosed clinical stages IB-IIIB(T3-4N2) NSCLC, received neoadjuvant chemotherapy + PD-1 inhibitors (PD-1 + Chemo group) or chemotherapy alone (Chemo group) followed by surgery between December 2018 and December 2020 were included. The clinicopathological characteristics were retrospectively reviewed and analyzed. There were 69 NSCLC patients in the PD-1 + Chemo group and 121 in the Chemo group. The major pathological response (MPR) rate in the PD-1 + Chemo group was 49.3%, higher than that of 19.0% in the Chemo group (p < 0.001). The 2-year disease-free survival (DFS) rate was 79.3% and 60.2%, respectively, in the two groups (p=0.048). Multivariate analysis identified surgical radicality (hazard ratio (HR), 2.954, 95% confidence interval (CI), 1.527-5.714, p=0.001), and pathological response (MPR(CR) vs. SD(PD), HR, 0.248, 95% CI, 0.107-0.572, p=0.001) to be independent prognostic factors for DFS. Lobectomy was performed in 73.9% and 66.1% of patients, respectively, and bronchial sleeve resection/bronchoplasty rate was also comparable (43.4% vs. 40.5%, p=0.688). More patients in the PD-1 + Chemo group received vascular sleeve resection/angioplasty (15.9% vs. 6.6%, p=0.039) and pericardial resection (10.1% vs. 2.5%, p=0.038). After propensity score matching analysis, pericardial resection rate was still slightly higher in the PD-1 + Chemo group (9.4% vs. 1.6%, p=0.05). Perioperative morbidities within 30 days and mortality in 90 days were comparable between groups (p > 0.05). Neoadjuvant chemoimmunotherapy for NSCLC is safe and feasible, with higher MPR rates, as well as favorable DFS than chemotherapy alone. Surgical complexity might be increased in certain patients, with comparable perioperative morbidity and mortality.

Adjuvant chemotherapy after curative D2 gastrectomy in Latin American patients with gastric cancer.

BackgroundGastric cancer (GC) is the fourth most common cause of cancer deaths around the world and the first cause of cancer deaths in Peru; however, there are no prospective trials for adjuvant chemotherapy in GC after curative gastrectomy in this country. The objective of this study was to evaluate the effectiveness of adjuvant chemotherapy in stage II–III gastric cancer patients who underwent D2 gastrectomy.MethodsWe included patients with stage II–III gastric cancer who underwent radical gastrectomy and D2 dissection between 2014 and 2016 at our institution. Patients received 3-week cycles of capecitabine (1,000 mg/m2 twice daily on days 1–14) plus oxaliplatin (130 mg/m2 on day 1) for 6 months. Survival curves were estimated with the Kaplan–Meier method, and the Cox proportional hazards model was used to identify prognostic factors for survival.ResultsIn total, 173 patients were included: 100 (57.8%) patients received adjuvant chemotherapy and surgery (AChS) and 73 (42.2%) surgery alone (SA). Three-year disease-free survival (DFS) was higher in the AChS groups (69%) than in the SA group (52.6%) (p = 0.034). Regarding overall survival (OS), 31 patients (31%) died in the AChS group compared with 34 (46.6%) in the SA group (p = 0.027). In the multivariate analysis, adjuvant chemotherapy was an independent prognostic factor for DFS (HR = 0.60; 95% CI = 0.37–0.97; p = 0.036) and OS (HR = 0.58; 95% CI = 0.36–0.95; p = 0.029). ACh showed consistent benefit in DFS and OS for patients with albumin >3.5 g/dL, lymphovascular and perineural invasion, pT4, pN2–3, pathologic stage (PS) IIIA and IIIB and lymph node ratio (LNR) > 13.1.ConclusionThese data suggest that adjuvant capecitabine and oxaliplatin reduce the recurrence and mortality in patients with stage II–III gastric cancer who underwent D2 gastrectomy. PS IIIA and IIIB and LNR > 13.1 benefited more from receiving adjuvant chemotherapy and poorly cohesive gastric carcinoma did not significantly reduce the rates of survival.

Predictive value of renal tumor contour irregularity score in pathological T3a upstaging of clinical T1 renal cell carcinoma: A multi-institutional study.

To explore the predictive value of renal tumor contour irregular degree (CID) in pathological T3a upstaging of clinical T1 renal cell carcinoma (RCC). We performed a retrospective multi-institutional review of 1,487 patients with clinical T1N0M0 RCC between January 2009 and June 2019. Kaplan-Meier survival curve and Cox regressions were used to analyze the prognostic factors of disease-free survival (DFS). Logistic regressions were performed to determine predictors of pathological T3a upstaging in clinical T1 RCC. Among 1,487 patients with cT1 RCC, 96 (6.5%) were pathological T3a upstaging. Multivariable logistic regression analysis showed that age (odds ratio [OR] = 1.022, 95% confidence interval [CI] = 1.001-1.042, P = 0.036), tumor maximum diameter(OR = 1.242, 95% CI = 1.042--1.480, P = 0.015) and CID (OR = 1.067, 95% CI = 1.051-1.083, P < 0.001) were independent predictors of pathological T3a upstaging. The area under the curve (AUC) of the prediction model that included the CID was 0.846, while the AUC of the prediction model that did not include CID was only 0.741, the difference was statistically significant (P < 0.001). Kaplan-Meier survival curve showed that patients with pathological T3a upstaging had significantly worse DFS than patients without pathological T3a upstaging (P < 0.001). Multivariable Cox analysis showed that pathological T3a upstaging (HR = 1.836, 95% CI = 1.013-3.329, P = 0.002) is an independent prognostic factor for DFS in patients with cT1N0M0 RCC. The predictive model of CID combined with tumor maximum diameter and age significantly improved the ability to predict pathological T3a upstaging in clinical T1 RCC, compared with the prediction model of tumor maximum diameter combined with age. The predictive model of CID combined with tumor maximum diameter and age may be applicable to patients considering partial vs. radical nephrectomy.

Prognostic Significance of HER3 Expression in Patients with Cervical Cancer.

Simple SummaryHuman epidermal growth factor receptors (HER) are involved in important signaling pathways such as cell growth, proliferation, and cell death. HER3 overexpression is associated with poor prognosis in various tumors, but prognostic relevance of HER3 in cervical cancer was not studied. We analyzed HER3 expression in cervical cancer tissue using immunohistochemistry (IHC) and compared disease-free survival (DFS) and overall survival (OS) based on HER3 expression. The presence of the HER3 protein was linked to a poor prognosis in cervical cancer. DFS and OS were linked to lymph node metastasis, histology, and HER3 protein expression. HER3 expression was connected to poor DFS and OS in both low- and high-risk groups of cervical cancer patients. We suggest that HER3 IHC testing might be a useful method for recognizing cervical cancer patients who are likely to progress.HER3 has been recognized to have an oncogenic role in various types of cancer. However, its prognostic significance has not been elucidated in cervical cancer. The aim of this study was to investigate the prognostic significance of HER3 expression in cervical cancer using immunohistochemistry (IHC). HER3 immunohistochemical staining was performed on the tumor tissue samples of 336 cervical cancer patients. The association between the clinicopathological characteristics and patient survival analysis was assessed according to HER3 expression. HER3 IHC staining was positive in 31.0% (104/336) of the cervical cancer patients. A higher proportion of adeno-/adenosquamous carcinoma was observed in the HER3-positive group (34.6%) than in the HER3-negative group (18.8%). In survival analysis, HER3 expression was significantly associated with poorer disease-free survival (DFS) and overall survival (OS) (p < 0.001 and p = 0.002, respectively). Multivariate analysis also indicated that HER3 expression was an independent prognostic factor for DFS (hazard ratio (HR) = 2.58, 95% confidence interval (CI) 1.42–4.67, p = 0.002) and OS (HR = 3.21, 95% CI, 1.26–8.14, p = 0.014). HER3 protein expression was a poor prognostic factor of survival in patients with cervical cancer. This finding could help to provide individualized management for these patients.

Prognostic value of pre-operative systemic immune-inflammation index and platelet to lymphocyte ratio in peritoneal carcinomatosis of ovarian origin

Background and objectivesThe aim of this study was to investigate the impact of systemic immune-inflammation index (SII), platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) on the survival outcomes of patients who underwent to cytoreductive surgery (CRS) and HIPEC for ovarian peritoneal carcinomatosis. MethodsA retrospective analysis of 68 cases following surgery at our department between 2015 and 2020 was performed. Receiver Operating Characteristic (ROC) curve was used with Youden index to calculate the optimal cutoff values for SII, PLR and NLR. ResultsUnivariate analysis revealed that high preoperative values of SII, PLR and NLR were correlated with worse overall survival (OS) and disease-free survival (DFS) in these patients. In the multivariable analysis, high SII was recognized as an independent prognostic factor for OS (CI 95%: 0.002- 3.835, p = 0.097) and high PLR was recognized as an independent prognostic factor for DFS (CI 95%: 0.253–2.248, p = 0.007). ConclusionSII and PLR could be useful prognostic tools to predict outcomes of patients who underwent to CRS and HIPEC for ovarian peritoneal carcinomatosis.

Expression comparison and clinical significance of PD-L1 (22C3) and PD-L1 (SP142) in triple negative breast cancer

Objective: To investigate the expression of programmed death ligand-1 (PD-L1, SP142) and PD-L1 (22C3) in triple-negative breast cancer (TNBC), and analyze their correlation with the clinicopathological factors and prognosis. Methods: The clinicopathologic data of 259 patients with TNBC treated in Cancer Hospital from August 2010 to December 2013 were collected. Whole section of surgical tissue samples were collected to conduct PD-L1 (SP142) and PD-L1 (22C3) immunohistochemical (IHC) staining. The PD-L1 expression in tumor cells and tumor infiltrating immune cells were visually assessed respectively, the relationship between PD-L1 expression and clinicopathologic characterizes were analyzed. Univariable and multivariable Cox proportional hazards regression models were used to test the correlations between PD-L1 expression and disease-free survival (DFS) and overall survival (OS). Results: The positive rates of SP142 (immune cell score, ICs≥1%) and 22C3 (combined positive score, CPS≥1) were 42.1%(109/259) and 41.3%(107/259) in TNBC tissues, respectively, with a total coincidence rate of 82.3%. The Kappa value of positive expression cases was 0.571 and the distribution difference of SP142 and 22C3 positive expression cases was statistically significant (P<0.001). The PD-L1 positive patients were less likely to have vascular invasion (P<0.05), but with higher histological grade and Ki-67 proliferation index (P<0.05). The recurrence/metastasis cases(8) of the patients with positive PD-L1 (SP142) was significantly lower than that of patients with negative PD-L1(SP142, 27, P=0.016). The positive expression of PD-L1 (SP142) patients were longer DFS (P=0.019). The OS of patients with positive PD-L1 (SP142) were longer than those with negative PD-L1 (SP142), but without significance (P=0.116). The positive expression of PD-L1 (22C3) was marginally associated with DFS and OS of patients (P>0.05). Conclusions: The expression of PD-L1 (22C3) is different from that of PD-L1 (SP142) in TNBC, and the two antibodies can't be interchangeable for each other in clinical tests. PD-L1 (SP142) status is an independent prognostic factor of DFS in TNBC. The DFS is significantly prolonged in patients with positive expression of PD-L1 (SP142).

Calculated Tumor-Associated Neutrophils Are Associated with the Tumor-Stroma Ratio and Predict a Poor Prognosis in Advanced Gastric Cancer.

The tumor-associated neutrophils (TANs) value and tumor—stroma ratio (TSR) are promising prognostic parameters in the tumor microenvironment. We aimed to evaluate the prognostic role and relationship of TANs and TSR in gastric cancer. Our study comprised 157 patients who underwent gastrectomy for advanced gastric cancer. TANs were assessed by immunohistochemical staining (CD15 and CD66b) and were analyzed with an image analyzer. TANs have been known to have different functional subpopulations of N1 (anti-tumor) and N2 (pro-tumor). We developed “calculated TANs with pro-tumor function (cN2; CD15 minus CD66b)”. The TSR was evaluated using hematoxylin and eosin staining. High-grade CD15-positive, cN2 in the tumor center, and TSR were significantly related to poor disease-free survival (DFS). TSR and cN2 were independent prognostic factors for DFS (hazard ratio (HR) = 2.614; p = 0.001, HR = 3.976; p = 0.002) and cN2 in the tumor center showed a positive correlation with TSR (R = 0.179, p = 0.025). While CD66b stained both N1 and N2, CD15 detected most of N2. Combining both markers revealed a novel cN2, which was an independent marker of poor prognosis. The transformation from N1 to N2 predominantly occurred in the tumor center, and was associated with TSR.

Postoperative Adjuvant Transarterial Chemoembolization Plus Tyrosine Kinase Inhibitor for Hepatocellular Carcinoma: a Multicentre Retrospective Study.

PurposeThis study aimed to assess the efficacy and safety of adjuvant transarterial chemoembolization (TACE) plus tyrosine kinase inhibitor (TKI) treatment in patients with hepatocellular carcinoma (HCC) with a high risk of early recurrence after curative resection.Patients and MethodsPatients from multiple centres were divided into postoperative adjuvant TACE with (n=57) or without (n=142) TKI administration groups. The disease-free survival (DFS) curve was depicted by the Kaplan–Meier method, and the difference between the two groups was tested using the log rank test. Univariate and multivariate Cox analyses were performed to identify independent risk factors for DFS. Additionally, three propensity score analyses were performed to minimise the potential confounding factors to facilitate a more reliable conclusion. Adverse events (AEs) were assessed according to the Common Terminology Criteria for Adverse Events, version 4.0.ResultsThe 1-and 2-year DFS rates of the TACE plus TKI treatment group were 45.5% and 34.9%, respectively, which were significantly better than those of the TACE alone group (26.8% and 18.3%, respectively). Multivariate analysis identified adjuvant TACE plus TKI treatment as an independent prognostic factor for DFS (hazard ratio: 0.611, 95% confidence interval: 0.408–0.915, P=0.017). Further analysis based on the various propensity score methods yielded similar results. Subgroup analysis showed that patients with tumour diameter ≥5 cm, tumour number <3, absence of hepatic vein tumour thrombus and bile duct tumour thrombus, ruptured tumours, and stage IIIB could benefit more from TACE plus TKI treatment (all P<0.05). Some patients (33.33%) experienced grade ≥3 AEs in the TACE plus TKI group.ConclusionTACE plus TKI treatment can reduce the incidence of early recurrence with tolerable adverse events in HCC patients at high risk of recurrence after hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.

Clinical significance and outcomes of bilateral and unilateral recurrent laryngeal nerve lymph node dissection in esophageal squamous cell carcinoma: A large-scale retrospective cohort study.

BackgroundThe survival benefits of recurrent laryngeal nerve lymph node dissection (RLNLD) in esophageal squamous cell carcinoma (ESCC) are still under debate, and the prognostic value of unilateral RLNLD has been rarely studied. Therefore, the aim of the present study was to investigate the clinical significance and outcomes of RLNLD in ESCC in a large‐scale cohort study, to shed light on the outcomes of unilateral RLNLD, and to identify the factors that affect the prognostic outcome of RLNLD.MethodsWe retrospectively reviewed 1153 patients with thoracic ESCC who underwent right thoracotomy with lymphadenectomy. The impact of RLNLD on disease‐free survival (DFS) and overall survival (OS) was estimated using the Kaplan–Meier method and Cox proportional hazard models. Inverse probability of treatment weighting (IPTW) was performed to adjust for differences in baseline variables in pairwise comparisons. Subgroup analysis of survival and postoperative complications was conducted for selective RLNLD.ResultsRLN lymph node (LN) metastasis was independently associated with tumor location and most other LN station metastases. RLNLD was an independent prognostic factor for DFS and OS. Both patients who underwent unilateral and bilateral RLNLD had significantly better DFS and OS than the non‐RLNLD patients. Furthermore, pairwise comparisons with IPTW confirmed these results, and we found that patients who underwent bilateral RLNLD had better survival than those who underwent unilateral RLNLD. However, subgroup analysis showed that there was no survival benefit and higher morbidity after bilateral RLNLD for patients with cancer in the lower thoracic esophagus, and elderly and female patients.ConclusionRLN LN metastasis is very frequent in ESCC, and both unilateral and bilateral RLNLD have considerable survival benefits. Selective RLNLD with better survival and lower morbidity was recommend for some defined subgroups.

The prognostic and predictive value of ESR1 fusion gene transcripts in primary breast cancer

BackgroundIn breast cancer (BC), recurrent fusion genes of estrogen receptor alpha (ESR1) and AKAP12, ARMT1 and CCDC170 have been reported. In these gene fusions the ligand binding domain of ESR1 has been replaced by the transactivation domain of the fusion partner constitutively activating the receptor. As a result, these gene fusions can drive tumor growth hormone independently as been shown in preclinical models, but the clinical value of these fusions have not been reported. Here, we studied the prognostic and predictive value of different frequently reported ESR1 fusion transcripts in primary BC.MethodsWe evaluated 732 patients with primary BC (131 ESR1-negative and 601 ESR1-positive cases), including two ER-positive BC patient cohorts: one cohort of 322 patients with advanced disease who received first-line endocrine therapy (ET) (predictive cohort), and a second cohort of 279 patients with lymph node negative disease (LNN) who received no adjuvant systemic treatment (prognostic cohort). Fusion gene transcript levels were measured by reverse transcriptase quantitative PCR. The presence of the different fusion transcripts was associated, in uni- and multivariable Cox regression analysis taking along current clinico-pathological characteristics, to progression free survival (PFS) during first-line endocrine therapy in the predictive cohort, and disease- free survival (DFS) and overall survival (OS) in the prognostic cohort.ResultsThe ESR1-CCDC170 fusion transcript was present in 27.6% of the ESR1-positive BC subjects and in 2.3% of the ESR1-negative cases. In the predictive cohort, none of the fusion transcripts were associated with response to first-line ET. In the prognostic cohort, the median DFS and OS were respectively 37 and 93 months for patients with an ESR1-CCDC170 exon 8 gene fusion transcript and respectively 91 and 212 months for patients without this fusion transcript. In a multivariable analysis, this ESR1-CCDC170 fusion transcript was an independent prognostic factor for DFS (HR) (95% confidence interval (CI): 1.8 (1.2–2.8), P = 0.005) and OS (HR (95% CI: 1.7 (1.1–2.7), P = 0.023).ConclusionsOur study shows that in primary BC only ESR1-CCDC170 exon 8 gene fusion transcript carries prognostic value. None of the ESR1 fusion transcripts, which are considered to have constitutive ER activity, was predictive for outcome in BC with advanced disease treated with endocrine treatment.

Retrospective literature review of primary neuroendocrine neoplasms of the breast (BNEN) in 209 Chinese patients: Treatment and prognostic factor analysis.

BackgroundThe prognostic factors and optimal choice of treatment for primary neuroendocrine neoplasms of the breast (BNEN) remain to be defined.MethodsPatients diagnosed with BNEN in China were retrospectively reviewed from the literature following the systematic search of China National Knowledge Infrastructure (CNKI), Chinese biomedical literature service system (sinomed), wanfang medical network, and Pubmed database. The clinical characteristics and different treatment modalities of patients with BNEN were evaluated.ResultsA total of 209 cases with BNEN were enrolled. There were 204 female and 5 male patients. The median age was 51 years old (range, 17–82). Out of 209 patients with BNEN, 208 (99.5%) patients were treated with surgery (SG), 44 patients (21.1%) had received radiotherapy (RT), 173 patients (82.8%) experienced chemotherapy (CT). A total of 158 patients with hormone receptor (HR) positive (87.8%, 158/180) were treated with endocrine treatment (ET). The median follow-up time was 52.4 months (range, 6–144). The 3-year overall survival (OS) rate and 3-year disease-free survival (DFS) rate for the whole group were 93.7% and 85.3%, respectively. In univariate analyses, Ki67 expression ≥20%, HR negative, neuroendocrine carcinomas (NECs) were associated with decreased OS and DFS (P < 0.05). Patients treated with anthracycline/taxane-containing CT regimens, or taxane-containing CT regimens had superior OS and DFS than patients without those (P < 0.05). Among 69 patients with stage I who received CT had no significant differences in OS or DFS compared to those without CT. Multivariate Cox regression analysis showed that gender, HR expression, pathologic subtype, and CT were independent prognostic factors for DFS but not OS (P > 0.05).ConclusionsThe best selection of patients to get the most benefit from different treatment modalities warrant further exploration. The clinicopathological parameters including gender, HR expression, ki67 expression, pathologic type, stage, tumor size, and lymph node status may serve as both indicators of diagnosis and prognosis, and guide treatment decisions for BNEN.

Use of the Advanced Lung Cancer Inflammation Index as a Prognostic Indicator for Patients With Cholangiocarcinoma.

BackgroundThis study aimed to assess the clinical utility of the advanced lung cancer inflammation index (ALI) as a prognostic indicator for patients with cholangiocarcinoma (CCA) and construct a prognostic nomogram based on ALI.MethodsA total of 97 CCA patients who received radical resection were included. The optimal cut-off point for ALI was identified by X-tile analysis. COX regression analysis were used to identify risk factors of overall survival (OS) and disease-free survival (DFS). A predictive nomogram for DFS was constructed.ResultsThe optimal cut-off value for preoperative ALI was 31.8. 35 (36.1%) patients were categorized into the low-ALI group and 62 (63.9%) patients into the high-ALI group. Low ALI was independently associated with hypoproteinemia and lower body mass index (BMI) (all P < 0.05). COX regression analysis revealed that preoperative ALI level (HR = 0.974, P = 0.037) and pathological TNM stage (HR = 7.331, P < 0.001) were independently correlated with OS for patients with CCA, and preoperative ALI level (HR = 0.978, P = 0.042) and pathological T stage (HR = 1.473, P = 0.035) remained to be independent prognostic factors for DFS in CCA patients. Using time-dependent ROC analysis, we found that ALI was better at predicting prognosis than other parameters, such as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and prognostic nutritional index (PNI) in terms of OS and DFS. A nomogram predicting DFS was built (C-index: 0.73 95%CI: 0.67–0.79).ConclusionsALI may be useful for prognosis assessment for patients with CCA.

Prognostic Significance of the Serosal Invasion in Hepatocellular Carcinoma

Background: The prognostic significance of serosal invasion (SI) was not clarified in patients with hepatocellular carcinoma (HCC). We investigated the impact of serosal invasion (SI) for the long-term outcome after curative surgical resection in patients with HCC. Methods: In total, 783 consecutive patients with HCC who underwent curative surgical resection without any preoperative treatment were histologically evaluated for SI. Patients with SI were classified into two groups: positive for SI (pSI; n=333) and negative for SI (nSI; n=450). Clinicopathologic features, disease-free survival (DFS), and overall survival (OS) were compared between patients with pSI and nSI. Results: The pSI group showed more aggressive tumor characteristics, such as higher tumor marker levels (alpha-fetoprotein, P=.023; protein induced by vitamin K absence-II, P=.016), larger tumor size (P<.001), higher prevalence of microvascular invasion (P=.002), and poorer differentiation (P=.002), than the nSI group. In survival analysis, 5-year DFS was 48.1%, 61.2% in the pSI, nSI, respectively (P<.001), while 5-year OS was 74.8%, 86.1%, respectively (P=.002). In multivariate analysis, SI was an independent prognostic factor for DFS (P=.043) and OS (P=.042). Conclusions: The SI was associated with more aggressive clinicopathologic characteristics and a higher risk of poor survival. Therefore, intensive careful follow-up is essential for patients with pSI after curative surgical resection in patients with HCC.

TRIM39 is a poor prognostic factor for patients with estrogen receptor-positive breast cancer and promotes cell cycle progression.

Tripartite motif (TRIM) family proteins are involved in various biological processes and the pathophysiology of cancers. However, the roles of TRIM39, a TRIM family member, in breast cancer is not well-understood. Here, we performed immunohistochemical study of TRIM39 protein in clinical estrogen receptor-positive (ER+ ) breast cancer tissues from 108 patients. TRIM39 immunoreactivity (IR) was positively correlated with advanced stage (p < 0.001), large invasive tumor size (p = 0.012), and positive lymph node status (p = 0.002). Positive TRIM39 IR was significantly correlated with short disease-free survival (DFS) (p = 0.001). Multivariate analysis revealed that the TRIM39 status is an independent prognostic factor in DFS (p = 0.049). Microarray analysis of MCF-7 breast cancer cells treated with siRNA revealed that TRIM39 knockdown downregulated the cell cycle- and cell division-related genes, including MLLT11, CDCA3, CDC25C, BIRC5, and ANP32E. Consistently, TRIM39 knockdown significantly suppressed proliferation and cell cycle transition to S phase in MCF-7 and 4-hydroxytamoxifen-resistant (OHTR) breast cancer cells. These results suggest that TRIM39 promotes ER+ breast cancer growth by promoting cell cycle progression.

Significance of preoperative blood tests in the prognosis of colorectal cancer: A prospective, multicenter study from Hungary.

BackgroundThe focus of this study was to analyze the prognostic value of different combinations of inflammatory and coagulation factors using preoperative blood and to appraise the clinical importance of these biomarkers in colorectal cancer patients.MethodsA prospective, multicenter study included patients undergoing radical colorectal surgery in three county hospitals. Inflammatory and coagulation markers were analyzed preoperatively.ResultsTwo hundred and one patients were included. We examined patients based on their tumor localization. Colon cancer group involved patients with the tumor localized in the colon (n = 105, 52.24%) and rectal cancer group the patients with the tumor in the rectum (n = 96, 47.76%). Examining coagulation factors, univariate Cox analysis of colon cancer patients showed that activated partial thromboplastin time (p = 0.020) was significantly associated with overall survival, but we could not prove it in multivariate analysis. In colon cancer patients, neutrophil‐to‐lymphocyte ratio (NLR, p < 0.001) was positively correlated with tumor size and had significant association (χ 2 = 5.48, p = 0.019, df = 1) with perineural invasion. Univariate and multivariate Cox analysis of colon cancer patients showed that NLR (p = 0.011 and p = 0.048) was significantly associated with disease‐free survival (DFS).ConclusionNLR was proved to be an independent prognostic factor for DFS in patients with non‐metastatic colon cancer. NLR might help to recognize the high‐risk patients between patients with the same tumor‐node‐metastasis stage and could help with the decision on adjuvant chemotherapy. Since the biomarkers in preoperative blood tests are habitually evaluated, NLR could be an inexpensive prognostic marker that can be easily assessed in clinical practice.

Impact of cumulative cisplatin dose in childhood nasopharyngeal carcinoma based on neoadjuvant chemotherapy response in the intensity-modulated radiotherapy era: a real-world study

BackgroundWe aimed to comprehensively investigate the optimal cumulative cisplatin dose during concurrent chemoradiotherapy (CC-CCD) for locoregionally advanced nasopharyngeal carcinoma (CA-LANPC) with different tumor responses after neoadjuvant chemotherapy (NAC).MethodsPatients with CA-LANPC who underwent NAC followed by cisplatin-based concurrent chemoradiotherapy were retrospectively analyzed. Evaluation of tumor response in patients was conducted by Response Evaluation Criteria for Solid Tumor (RECIST) 1.1 after two to four cycles NAC. Multivariate Cox proportional hazards models were used for prognosis. Recursive partitioning analysis (RPA) was conducted to classify participates and predict disease-free survival (DFS).ResultsOne hundred and thirty-two patients with favorable response after NAC were included. The median CC-CCD was 163 mg/m2 (IQR, 145–194 mg/m2), and 160 mg/m2 was selected as the cutoff point to group patients into low and high CC-CCD groups (< 160 vs. ≥ 160 mg/m2). There was significant improvement in 5-year DFS (91.2% vs. 72.6%; P = 0.003) for patients receiving high CC-CCD compared to those receiving low CC-CCD. Multivariate analysis revealed that CC-CCD, T stage, and Epstein–Barr virus (EBV) DNA were independent prognostic factors for DFS (P < 0.05 for all). Patients were further categorized into two prognostic groups by RPA: the low-risk group (T1-3 disease with regardless of EBV DNA, and T4 disease with EBV DNA < 4000 copy/mL), and the high-risk group (T4 disease with EBV DNA ≥ 4000 copy/mL). Significant 5-year DFS improvement was observed for the high-risk group (P = 0.004) with high CC-CCD. However, DFS improvement was relatively insignificant in the low-risk group (P = 0.073).ConclusionsCC-CCD was a positive prognostic factor for responders after NAC in CA-LANPC. Furthermore, CC-CCD ≥ 160 mg/m2 could significantly improve DFS in the high-risk group with CA-LANPC, but the benefit of high CC-CCD in the low-risk group needs further study.

Matrix metalloproteinase‑1 expression is regulated by HIF‑1‑dependent and epigenetic mechanisms and serves a tumor‑suppressive role in gastric cancer progression.

The matrix metalloproteinase (MMP) family is associated with degradation of the extracellular matrix and is known to promote cancer invasion. The present study aimed to investigate the biological role of MMP-1 in gastric cancer cells and analyze the association between MMP-1 expression and the clinical outcomes of gastric cancer patients. In the present study, hypoxia accelerated invasion, accompanied by elevated MMP-1 expression in the gastric cancer cell line 58As9. Additionally, hypoxia-inducible factor-1α (HIF-1α) knock- down in 58As9 cells reduced MMP-1 expression under hypoxic conditions. Treatment with 5-aza-2-deoxycytidine and trichostatin A restored MMP-1 expression in the MMP-1-deficient cell lines MKN45 and MKN74. These results indicated that MMP-1 expression was controlled by both HIF-1α-dependent and epigenetic mechanisms in gastric cancer cell lines. In addition, MMP-1 knockdown impaired the hypoxia-induced invasiveness of 58As9 cells, implicating MMP-1 in the elevated invasion. By contrast, knockdown enhanced the proliferative ability of 58As9 cells, whereby expression of cell cycle-related genes was subsequently altered. In nude mouse models, the knockdown accelerated the growth of xenograft tumor and the development of peritoneal dissemination. In an immunohistochemical study using 161 surgically resected cancer tissues, the Ki67 score was significantly higher in the group with low MMP-1 expression (P<0.001). Disease-free survival (DFS) and disease-specific survival (DSS) were both significantly reduced in patients with low MMP-1 expression (log-rank test; DFS: P=0.005; DSS: P=0.022). Multivariate analysis demonstrated that MMP-1 expression was an independent prognostic factor for DFS and DSS [DFS: HR=2.11 (1.22–3.92) P=0.005, DSS: HR=2.90 (1.23–8.50) P=0.012]. In conclusion, the present study indicated that MMP-1 may serve as a tumor-suppressive factor that inhibits gastric cancer progression, although it promoted invasion in vitro.
