s the value of non-predominant micropapillary pattern to predict poor prognosis. A reliable nomogram model was constructed to provide personalized survival predictions.
Tumor-associated macrophages (TAMs) are the major immune cells in tumor microenvironment. The prognostic significance of TAMs has been confirmed in various tumors. However, whether TAMs can be prognostic factors in clear cell renal cell carcinoma (ccRCC) is unclear. In this study, we aimed to clarify the prognostic value of TAMs in ccRCC.
We searched PubMed, Embase, and the Web of Science for relevant published studies before December 19, 2020. Evidence from enrolled studies were pooled and analyzed by a meta-analysis. Hazard ratios (HRs) and odd ratios (ORs) with 95% confidence intervals (CIs) were computed to evaluate the pooled results.
Both of high CD68+ TAMs and M2-TAMs were risk factors for poor prognosis in ccRCC patients. The pooled HRs indicated that elevated CD68+ TAMs correlated with poor OS and PFS (HR 3.97, 95% CI 1.39-11.39; HR 5.73, 95% CI 2.36-13.90, respectively). For M2-TAMs, the pooled results showed ccRCC patients with high M2-TAMs suffered a worse OS and shorter PFS, with HR 1.32 (95% CI 1.16-1.50) and 1.40 (95% CI 1.14-1.72), respectively. Also, high density of TAMs was associated with advanced clinicopathological features in ccRCC.
TAMs could be potential biomarkers for prognosis and novel targets for immunotherapy in ccRCC. Further researches are warranted to validate our results.

Non-small cell lung cancer (NSCLC) patients with
mutations and amplification may benefit from HER2-targeted therapy, including afatinib. However, the data regarding the clinical activity of afatinib in Chinese patients with NSCLC harboring
alterations are limited.
We retrospectively included metastatic NSCLC patients harboring
alterations who treated with afatinib. The clinical outcomes included overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). The genomic profiling data after progression on afatinib were analyzed.
We included 54 patients harboring
mutations and 12 patients harboring
amplification. The ORR was 24% (95% CI, 16-36%), the median PFS was 3.3 months (95% CI, 2.2-4.4), and the median OS was 13.9 months (95% CI, 11.4-16.5). Patients with
exon 20 mutations had numerically worse ORR (17%
42%), shorter PFS (2.6
5.8 months, HR, 2.5; 95% CI, 1.2-5.5;
= 0.015) and OS (12.9
33.3 months, HR, 4.4; 95% CI, 1.3-14.8;
= 0.009) than patients with other mutations. For HER2-amplified patients, the ORR was 33% (95% CI, 14-61%), the median PFS was 3.3 months (95% CI, 2.6-4.0), and the median OS was 13.4 months (95% CI, 0-27.6). The most frequently mutated genes in afatinib-resistant patients were
(44%) and
(33%). Three afatinib-resistant patients harbored secondary
alterations.
Our results suggest that afatinib has a promising anti-tumor activity in patients with NSCLC harboring
alterations. To our knowledge, this is the largest retrospective study about the clinical activity of afatinib in NSCLC patients with
alterations.

Amine oxidase copper containing 1 (
) is a gene whose biological function in colorectal cancer (CRC) has not been elucidated. Therefore, the purpose of this study was toinvestigate the clinical significanceof
expression in CRC and its biological function in CRC cell lines.
expression levels were examined in paired CRC and peritumoral tissues, and distant liver metastatic tissues were examined using quantitative real-time PCR, western blotting, and immunohistochemistry staining. The log-rank test and Cox regression model were used to analyze the relationship between
expression and prognosis. Proliferation assays (Cell Counting Kit-8 and colony formation assays), migration assays (Transwell and wound healing assays) and xenograft tumor formationin nude mice were performed to assess the biological role of

Patients with small hepatocellular carcinoma (HCC) (3 cm) still have a poor prognosis. The purpose of this study was to develop a radiomics nomogram to preoperatively predict early recurrence (ER) (2 years) of small HCC.
The study population included 111 patients with small HCC who underwent surgical resection (SR) or radiofrequency ablation (RFA) between September 2015 and September 2018 and were followed for at least 2 years. Radiomic features were extracted from the entire tumor by using the MaZda software. ICG-001 in vivo The least absolute shrinkage and selection operator (LASS0) method was applied for feature selection, and radiomics signature construction. A rad-score was then calculated. Multivariable logistic regression analysis was used to establish a prediction model including independent clinical risk factors, radiologic features and rad-score, which was ultimately presented as a radiomics nomogram. The predictive ability of the nomogram was evaluated using the area under the receiver operating characteristic (ROC) curve and internal validation was performed
bootstrap resampling and 5-fold cross-validation method.
