The tumors of central nervous system refer to a group of benign and malignant diseases originating from tissues or structures within the central nervous system. Common tumors of central nervous system are sporadic, but a few have familial onset. Compared with sporadic brain tumors, the clinical symptoms, diagnostic ideas and follow-up review plans of familial brain tumors are more complicated. The multidisciplinary diagnosis and treatment (MDT) mode usually refers to a treatment mode in which a case involving multiple organs and systems is discussed, and the best treatment plan is formulated for the patient based on the comprehensive opinions of various disciplines. Because familial brain tumors often involve multiple organs, multiple disciplines and multiple systems, and their low incidence leads to less clinical experience for neurosurgeons, the MDT model is more conducive to efficient diagnosis, treatment and management of familial brain tumors. This review elaborates on the neurosurgeon-led MDT model, and introduces the latest research on the epidemiology, genetic characteristics, clinical manifestations, diagnostic ideas and multidisciplinary management of familial brain tumors.

Although the diagnosis of glioma is constantly changing with the update of WHO diagnostic guidelines, the current treatment methods are still mainly surgical treatment, supplemented by radiotherapy and chemotherapy. It is a pity that the treatment effect of high-grade glioma is still unsatisfactory. How to improve the prognosis of patients is the key problem in the field of medical exploration of glioma. It is gratifying that many new ideas and methods have emerged in the diagnosis and treatment of glioma, in which some trials represented by tumor treating fields have achieved good results in clinical research, moreover, the fields of immunotherapy and targeted therapy have developed too. This paper aims to share and explore these new methods and summarize the progress of diagnosis and treatment of glioma.

Objective To investigate the indications of optic canal decompression in the patients with front-orbital fibrous dysplasia and the methods of intraoperative optic canal localization and decompression. Methods We collected 30 cases of fibrous dysplasia. All patients had sufficient images assessment. Patients with symptoms underwent surgery, including front-orbital cranioplasty and optic canal decompression. The frontotemporal epidural approaches were used. If there was a proptosis, the approach was extended with the removal of superior orbital ridge. Six patients undertook intraoperative CT and MRI fusion navigation, assisting in confirming the trunk, orbital and cranial orifice of optic nerve. During the operation, the optic canals were decompressed by three-bits method, to confirm the position of optic nerve. Results There were 30 cases of optic canal decompression and one case of vision loss. The visual acuity and vision field of the remaining patients improved to varying degrees. The proptosis disappeared or alleviated after the operation. Thirteen cases were reconstructed with normal internal plate, five cases with titanium plate, nine cases without reconstruction, and two cases were paved with proliferative broken bone on the orbital top; one case recurred with exophthalmos again after five years, but the visual acuity did not decline. Conclusion For the patients with front-orbital fibrous dysplasia, active surgical treatment should be taken, optic canal decompression should be chosen for diminution of vision, craniofacial anaplasty and orbital decompression should be performed in patients with facial deformity. The epidural approach is a good option to locate the optic nerve from the orbital orifice or cranial orifice. Combined with the three-bits method, we can achieve safe and meticulous optic nerve decompression.

Immunotherapy is considered as the fourth cancer treatment after surgery, radiotherapy and chemotherapy. With the in-depth research on immunotherapy in recent years, especially immuno-checkpoint inhibitors, PD-1/PD-L1 pathway inhibitors have been approved for the treatment of many cancer species. But due to the immune response of tumor cells through multiple drug-resistant mechanisms, immuno-checkpoint blockade has some problems, such as low overall response rate, primary or secondary drug resistance and so on. This paper expounds the mechanism of tumor immune resistance and explores strategies for further treatment after drug resistance, which provides a new theoretical and clinical basis for improving the response rate of immune checkpoint inhibitors and reducing the probability of immune resistance.

ZHENG Jianzhou, BAI Yu, QI Chunjian
Cancer Research on Prevention and Treatment. 2022, 49 (06): 563-568.   DOI: 10.3971/j.issn.1000-8578.2022.21.1193
Abstract( 91 PDF (9482KB)  ( 77 ) )   HTML ()
Objective To investigate the effects of lncRNA FENDRR on the proliferation, migration, invasion and apoptosis of LUSC H226 cells and its molecular mechanism. Methods The expression levels of FENDRR in normal lung epithelial cells BEAS, lung adenocarcinoma A549 and H1299 cells and LUSC H226 cells were detected by qRT-PCR. H226 cells were transfected with FENDRR-siRNA as the experimental group, or with FENDRR-siNC as a negative control group. Cell proliferation was detected by CCK-8 assay. Cell migration and invasion were detected by Transwell assay. Cell apoptosis was detected by flow cytometry. The protein expression levels of MEK, p-MEK, ERK and p-ERK were determined by Western blot. Results FENDRR levels in H226 cells were significantly lower than those in normal lung epithelial cells. Compared with the negative control group, the knockdown of FENDRR could significantly promote the proliferation, migration and invasion of H226 cells, inhibit the cell apoptosis, and increase the protein levels of p-MEK and p-ERK. The addition of ERK inhibitor U0126 rescued the effect of FENDRR knockdown on H226 cells. Conclusion The knockdown of lncRNA FENDRR can promote the proliferation, migration and inhibit the apoptosis of H226 cells through ERK/MAPK pathway.

Cancer Research on Prevention and Treatment. 2022, 49 (06): 569-574.   DOI: 10.3971/j.issn.1000-8578.2022.21.1181
Abstract( 141 PDF (5601KB)  ( 60 ) )   HTML ()
Objective To explore the related genes that play a key regulatory role in cisplatin resistance in lung adenocarcinoma. Methods Bioinformatics methods were used to download the differentially-expressed genes between cisplatin sensitive group and drug resistant group in patients with lung adenocarcinoma in TCGA database and GDSC database. GO function analysis and KEGG pathway enrichment analysis were carried out to analyze the differentially-expressed genes. The protein-protein interaction network was constructed and hierarchical cluster analysis was carried out to screen the key genes. The key genes were verified at the cell level by real-time fluorescence quantitative PCR and ELISA. Then the expression of the selected key gene in A549/DDP cells was silenced by siRNA and its sensitivity to cisplatin was detected. Results We screened out 1 78 differentially-expressed genes. After cluster analysis, CXCL9, CXCL10, NKX2-1 and SFTPA1 were regarded as the key genes of cisplatin resistance in lung adenocarcinoma. CXCL10 was temporarily selected for subsequent verification and function experiment. The mRNA expression of CXCL10 in A549/DDP cells was significantly higher than that in A549 cells (P<0.001), and the expression of CXCL10 protein in the supernatant of A549/DDP cells was higher than that in A549 cells, which were consistent with the prediction of bioinformatics. The sensitivity of A549/DDP cells to DDP increased after silencing CXCL10 expression. Conclusion CXCL10 is a key gene to regulate cisplatin resistance in lung adenocarcinoma. Downregulating the expression of CXCL10 can become a potential target for reversing cisplatin resistance in lung adenocarcinoma.

Objective To investigate the expression of Pin1 protein in HepG2 cells under endoplasmic reticulum stress (ERS) and its effect on cell proliferation and apoptosis. Methods The THLE3 cells were treated with tunicamycin (TM) (TM group) or DMSO (DMSO group) for 48h. The HepG2 cells were treated with TM (TM group), ATRA(ATRA group), TM+ATRA (TM+ATRA group) or DMSO (DMSO group) for 48h. The protein levels of Bip and Pin1 were detected by Western blot, cell proliferation was detected by CCK-8 assay, and cell apoptosis was detected by flow cytometry. Results The expression of Bip both increased in THLE3 and HepG2 cells treated with TM, indicated that TM effectively induced ERS in cells. Compared with the DMSO group, the protein level of Pin1 in THLE3 cells in TM group was decreased with the increasing of TM concentration (P<0.001). In TM+ATRA group, with the increasing of TM concentration, the expression of Pin1 was decreased in HepG2 cells (P<0.01). The inhibitory rates was (29.33±4.73)% in HepG2 cells in TM group, significantly lower than (60.33±2.08)% in THLE3 cells in TM group (P<0.001). In TM+ATRA group, the growth inhibition rates was increased to (60.33±6.03)% in HepG2 cells. The apoptosis rate of THLE3 cells in TM group was (22.25±0.78)%, significantly higher than (3.57±0.31)% in DMSO group (P<0.01). The apoptosis rates of HepG2 cells in ATRA group and TM+ATRA group were significantly higher than that in the DMSO group ((10.03±0.49)% vs. (5.10±1.00)%, P<0.05 and (23.70±0.75)% vs. (5.10±1.00)%, P<0.01). Conclusion HepG2 cells resist ERS-induced apoptosis by maintaining Pin1 protein level. Reducing the protein level of Pin1 can significantly inhibit the cell proliferation and induce apoptosis.

Abstract( 93 PDF (7838KB)  ( 48 ) )   HTML ()
Objective To investigate the expression of MAD2L1 in lung adenocarcinoma and its effect on the prognosis and immune microenvironment of patients. Methods The difference of MAD2L1 expression in lung adenocarcinoma tissue and normal lung tissue was analyzed by TCGA and GEO database. Survival analysis was carried out to evaluate the prognostic significance of MAD2L1 gene expression in lung adenocarcinoma patients. StarBase database was used to construct miRNA-MAD2L1 regulatory network of lung adenocarcinoma. The relation between the expression of MAD2L1 and immune cell infiltration in lung adenocarcinoma was analyzed by TIMER database. Results The expression of MAD2L1 was upregulated in lung adenocarcinoma, and the high expression of MAD2L1 was significantly correlated with pathological stage and lymph node metastasis of lung adenocarcinoma. The patients with high expression of MAD2L1 had a poor prognosis. miR-101-3p/MAD2L1 axis was identified as the most potential upstream regulation pathway of MAD2L1 in lung adenocarcinoma. The expression level of MAD2L1 was significantly correlated with tumor immune cell infiltration and immune checkpoint expression. Conclusion MAD2L1 is highly expressed in lung adenocarcinoma, which is related to poor prognosis and tumor immune infiltration. MAD2L1 can be used as a potential target for the treatment of lung adenocarcinoma.

Objective To investigate the expression of lncRNA HOTAIR, HOTAIR, CRNDE and AFAP1-AS1 in lung cancer patients with bone metastasis (LCWBM), and to elucidate the diagnostic value of lncRNAs for LCWBM. Methods Serum was collected from 38 LCWBM patients and 38 lung cancer without bone metastasis (LCWOBM) patients. Questionnaires were used to collect basic information of patients. Fasting peripheral venous blood of patients was collected to separate serum. qRT-PCR was used to measure the expression levels of four serum lncRNAs, and their diagnostic value for LCWBM was analyzed. Results The expression of serum HOTAIR was decreased in LCWBM patients, compared with LCWOBM patients (P<0.05); the AUC of serum HOTAIR diagnosing LCWBM was 0.722 (sensitivity was 70.0%, specificity was 81.3%). And the level of serum HOTTIP was significantly increased in LCWBM patients, compared with LCWOBM patients (P<0.05); AUC of serum HOTTIP diagnosing LCWBM was 0.784 (sensitivity was 100.0%, specificity was 45.5%). The AUC of serum HOTAIR combined with HOTTIP diagnosing LCWBM was 0.818 (sensitivity, specificity, positive predictive value and negative predictive value were 87.5%, 72.7%, 70.0% and 88.9%, respectively). Conclusion Serum lncRNA HOTAIR and HOTTIP might be potential diagnostic biomarkers for bone metastases in lung cancer patients.

Cancer Research on Prevention and Treatment. 2022, 49 (06): 599-605.   DOI: 10.3971/j.issn.1000-8578.2022.21.1240
Abstract( 106 PDF (4848KB)  ( 42 ) )   HTML ()
Abstract: Objective To identify the potential prognostic biomarkers of the immune-related genes signature for patients with hepatocellular carcinoma (HCC). Methods Original HCC data were downloaded from TCGA, and the immune activity of each sample was calculated by ssGSEA. HCC samples were divided into high and low immune cell infiltration groups by “GSVA” package and “hclust” package. The ESTIMATE algorithm scored the tumor microenvironment in each HCC sample. The “limma” package and Venn diagram identified effective immune-related genes. Univariate Cox, Lasso regression and multivariate Cox regression analyses were used to explore key genes. The “rms” package was used to create nomograms and draw calibration curves. Results Compared with the high immune cell infiltration group, the tumor purity of the samples in the low immune cell infiltration group was higher, the immune score, ESTIMATE score and stromal score were lower. In the high immune cell infiltration group, the immune components were more abundant, and the expression levels of TIGIT, PD-L1, PD-1, LAG3, TIM-3, CTLA4 and HLA family were higher. Multivariate Cox regression analysis showed that four immune-related genes (S100A9, HMOX1, IL18RAP and FCER1G) were used to construct the prognosis model. Compared with other clinical features, the risk score of this prognostic model was recognized as an independent prognostic factor. Conclusion This study identified the immune-related core genes which may be used in targeted therapy and immunotherapy of HCC.

Abstract( 129 PDF (8241KB)  ( 55 ) )   HTML ()
Objective To establish a lncRNA prognostic risk model for gastrointestinal tumors based on the TCGA database and evaluate the prognosis of patients. Methods We collected the data of patients with esophageal cancer, gastric cancer, colon cancer and rectal cancer in the TCGA database. Univariate Cox analysis, Lasso and multivariate Cox analysis were performed to construct the prognostic risk scoring model. The model was validated and tested for independence. Time-dependent ROC curve analysis was performed to evaluate the clinical application value of the model. Results We established a prognostic risk model based on 1 3 lncRNAs. The three-year AUC of the training set and the validation set were 0.746 and 0.704, respectively. The pan-cancer data set was divided into high- and low-risk groups for survival analysis. The 5-year survival rate of the low-risk group was significantly higher than that of the high-risk group; among all cancer types, the five-year survival rates of the low-risk group were higher than those of the high-risk group. Multivariate Cox analysis showed that the risk score could be an independent indicator of prognosis. Conclusion The 1 3-gene prognostic risk score model is constructed successfully. The risk score obtained by this model can be used as an independent prognostic predictor of the patients with gastrointestinal cancer.

Objective To determine the prosthesis survival and limb function after revision of global modular replacement system (GMRS) tumor prosthesis. Methods We retrospectively analyzed the clinical data of 16 patients who developed aseptic loosening of lower extremity tumor prosthesis and subsequently received revision with GMRS from 2009 to 2012. Kaplan-Meier method was used to calculate the 5- and 8-year survival rates of the prosthesis. The MSTS function scale was used to evaluate the functional outcomes. Results The average follow-up time was 90 months (52-11 8 months). The 5- and 8-year survival rates of GMRS prosthesis were both 94%. After revision, two patients failed, including one case of infection and one case of repeated aseptic loosening. The average interval between the first joint replacement and revision surgery was 81 months (27-187 months). Until the last follow-up, 93.3%(14/15) of the patients did not develop repeated aseptic loosening, 85.7%(12/14) of the patients who underwent GMRS revision had a longer loosening-free survival than those with the primary joint replacement (90.6±19.3 vs. 43.4±29.7 months, P=0.001). The average MSTS functional score was 27.7(24-30). Conclusion The incidence of repeated aseptic loosening for GMRS prosthesis is low and the limb function is good. The reported technique is satisfactory in the middle and long term.

The papillary thyroid cancer (PTC) patients have general good prognosis, but the relapse occurred in 20%-30% patients after initial treatment, which resulted in poor prognosis and treatment difficulty. 131I can act as a part of postoperative adjuvant therapy for the initial standard treatment of middle- or high-risk PTC patients, and it still could play important roles in the diagnosis and treatment of recurrent PTC. 131I can contribute to early detection, accurate location and iodine uptake evaluation of recurrence foci and is helpful for the subsequent treatment scheme. 131I can serve as a part of radical treatment for small recurrent foci, postoperative adjuvant treatment for resectable lesions and palliative treatment for unresectable ones. This paper reviews the value of 131I treatment as the adjuvant therapy followed by reoperation in recurrent PTC.
