To explore the development of global tumor immunotherapy in the past 20 years, and analyze the research status, hotspots and trends to provide theoretical support for subsequent research. CiteSpace 5.6.R2 software were used to analyze 290 articles related to tumor immunotherapy research from the Web of Science core data set from 2000 to 2019. CiteSpace was used to draw related visual maps and tables of coauthors, cooperating countries, cooperating institutions, literature and journal co‐citation, keyword co‐occurrence, and cluster analysis. The total amount of papers published in the field of tumor immunotherapy research has gradually increased. After receiving the Nobel Prize in Physiology or Medicine in 2018, the number of papers published in the field of research in tumor research reached 20. We found that the United States has the largest number of papers in all countries and China ranks 6. “Proceedings of the National Academy of Sciences of the United States of America,” “Journal of Immunology,” “Cancer Research,” “New England Journal of Medicine,” “Blood” is the top five core academic journals in this field. Cancer, disease, and tumor necrosis factor are the three keywords with the highest highlighting intensity. Comprehensive analysis shows that the coauthors, co‐institutions, and co‐cited journals of the literature are mostly concentrated in the United States. The rise of immunotherapy provides a new direction for tumor treatment. From 2018 to 2019, the number of literatures on tumor immunotherapy worldwide increased sharply. Immunotherapy combined with specific diseases is the current research frontier and hotspot.

To explore the application and effect evaluation of case management nursing practice mode in patients with nasopharyngeal carcinoma receiving precision radiotherapy. Fifty patients with nasopharyngeal carcinoma diagnosed for the initial treatment in our hospital from February 2020 to October 2020 were selected as the control group and 50 patients with the same condition in the same period were selected as the experimental group. The experimental group was trained by nurses to implement case management nursing practice mode for nasopharyngeal cancer patients; in the control group, nasopharyngeal cancer patients were treated with general nursing routine, such as health education and discharge guidance before chemotherapy and radiotherapy. Compared with the control group, self‐care ability and patient satisfaction of experimental group were improved to a certain extent, and the differences were statistically significant (p < .05). The nursing practice mode of case management is suitable for patients with cancer and chronic diseases. The mode can provide continuous and high‐quality nursing for patients, improve patients' self‐care ability, satisfaction with hospitalization, and so forth, and thus is worthy of clinical application.

Adverse drug reaction (ADR) is quite common and poses a huge medical and economic burden all over the world. Understanding the role of genetic variant and microbes in drug response and using this knowledge in prescribing drugs will help to reduce ADR and improve drug efficacy. We have collected pharmacogenomic and pharmacomicrobiomics data currently available for several drugs. We found both the associated genetic variants and microbes for only five drugs (Fluorouracil, Irinotecan, Methotrexate, Ribavirin, Warfarin). Among them, 14 single nucleotide polymorphisms (SNPs) were found to be associated with response to fluorouracil, 6 with Ribavirin, 8 with warfarin, 1 with irinotecan, and 3 with methotrexate. Allelic distribution shows significant differences among different populations and African population have lower extent of linkage disequilibrium than non‐Africans. Various microbial species are associated with either increasing or decreasing drug effectivity or toxicity of those drugs. This study indicates a great potential if these two fields are explored more and used in combination for drug therapy.

We retrospectively enrolled 325 gastric cancer (GC) patients to investigate the associations of programmed death ligand‐1 (PD‐L1) expression with clinicopathological characteristics by different scoring methods and different cutoff values. PD‐L1 expression was evaluated by the tumor proportion score (TPS) and the combined positive score (CPS). The positive rate of PD‐L1 TPS ≥1%, CPS ≥1, CPS ≥5 and CPS ≥10 in our study were 12.0%, 87.4%, 69.8% and 42.2%, respectively. Multivariate analysis showed that PD‐L1 CPS ≥5 was related to high expression of Ki67 (OR = 2.658, 95% CI: 1.401–5.045, p = .003) and pTNM staging (p = .033). PD‐L1 CPS ≥10 was correlated with larger tumor size (OR = 2.322, 95% CI: 1.052–5.127, p = .037) and lymph node metastasis (OR = 2.495, 95% CI: 1.293–4.814, p = .006). It is expected that these results can provide a reference for screening GC patients with high PD‐L1 expression level.

With the change of medical model, the cancer nurses should not only pay attention to patients' physical pain, but also patients' psychological distress, which requires cancer nurses to have a high quality of humanistic care. This study aims to explore the humanistic care quality of new nurses in cancer hospital and effects of the narrative medicine‐based training program on the new nurses of cancer hospital. A total of 101 new nurses in a cancer hospital received the narrative medicine‐based training in 2020. Before and after the training, they were investigated with humanistic care quality questionnaire and empathy ability questionnaire. The course included narrative therapy overview, narrative medicine overview, narrative nursing, psychological nursing cases of cancer patients, and so on. After training, the total score of the humanistic care and quality empathy ability increased significantly, and the comparison was statistically significant. The total score of empathy after the training (98.44 ± 2.23) was higher than the score before the training (86.35 ± 7.53) (p < .05). The total score of humanistic care quality after the training (184.45 ± 14.34) was higher than the score before the training (161.45 ± 15.45) (p < .01). The scores of all dimensions were statistically significant. The narrative medicine‐based training program could increase the empathy ability of the new cancer nurses and improve the humanistic care quality. This program is suitable for clinical promotion and application. The study findings could have implications for medical institute to increase the humanistic care quality of new nurses.

ALKBH5 is the major demethylase of ribonuclease m6A and exerts these multiple biological functions in cancer. In this study, we mainly explore the use of ALKBH5 in the development and progression of osteosarcoma and elucidate the potential molecular mechanisms by which it functions. Relative to human osteoblast cell lines (NHOst), we detected ALKBH5 expression in osteosarcoma cell lines (HOS, U2OS, and MG‐63) by RT‐PCR and western blot. By overexpression and knockout of ALKBH5 gene, to observe the effect of ALKBH5 on apoptosis, invasion and epithelial‐mesenchymal transition (EMT) of osteosarcoma cells, as well as the effect of Notch signaling pathway. We found that ALKBH5 was significantly higher in osteosarcoma cell lines than in osteoblastic cell lines. In addition, ALKBH5 overexpression promoted the proliferation, migration, and invasion of osteosarcoma cells, and simultaneously activated Notch signaling pathway and up‐regulated E‐cadherin protein. Knockout of ALKBH5 inhibited these effects in osteosarcoma cells. It was also found that up‐regulation of ALKBH5 could promote the proliferation of osteosarcoma cells in vitro and in vivo. ALKBH5 can be involved in osteosarcoma development through Notch signaling pathway regulation. ALKBH5 is therefore expected to be a new target in the treatment of osteosarcoma.

Hypocalcemia is a fatal electrolytic disorder defined as corrected serum total calcium levels <2.12 mmol/L (8.5 mg/dl). Drug‐induced hypocalcemia is uncommon. A female patient was admitted to Jiangsu Cancer Hospital and diagnosed with nasopharyngeal carcinoma; she developed hypocalcemia after chemotherapy with albumin‐bound paclitaxel. Its diagnosis is incredibly difficult. Confirmatory diagnosis depends on serum total calcium levels and electrocardiogram.

Long noncoding RNA (lncRNA) may act as a biomarker to predict the overall survival (OS) of cancer patients. This study is to explore the prognostic signature of gastric cancer based on N7‐methylguanosine‐related lncRNAs to evaluate the prognosis and immune status of patients. The lncRNAs were identified by co‐expression analysis, univariate and, stepwise multivariate Cox regression. Then, patients were divided into the high‐ and low‐risk groups. Time‐dependent receiver operating characteristics, log‐rank test, principal component analysis, and nomogram were used to analyze the risk model. Finally, different immune status between the two groups was revealed by gene set enrichment/variation analysis (GSEA/GSVA), CIBERSORTx, and ESTIMATE algorithm. The difference in tumor mutation burden and drug sensitivity between the two groups was also explored. Three lncRNAs (LINC00412, REPIN1‐AS1, and RPH3AL‐AS1) were employed to construct the prognostic model. The OS rate of the high‐risk group was lower than the low‐risk group. GSEA and GSVA indicated this model was associated with immune‐related function, such as negative regulation of humoral immune response. Furthermore, the relative fractions of regulatory T cells, activated NK cells, and so forth, were significantly higher in the high‐risk group. And ESTIMATE revealed the different immune scores between the two groups. Finally, six compounds were screened out as candidate therapy drugs, and the prognostic model revealed higher performance than TP53 mutation status. The prognostic signature was competent in predicting the prognosis of gastric cancer and the immune microenvironment, which could guide individualized treatment for gastric cancer in the clinic.
