Optimal response to tislelizumab plus chemotherapy in metastatic triple-negative breast cancer: a case report and literature review.

Metastatic triple-negative breast cancer (mTNBC) has the worst prognosis among breast cancer subtypes. Immune checkpoint inhibitors (ICIs) plus chemotherapy have promising survival benefits. Herein, we report a 51-year-old woman whose metastatic lesions were diagnosed as triple-negative subtype and who received tislelizumab plus eribulin treatment and achieved excellent efficacy. To our knowledge, this study is the first attempt to present tislelizumab in combination with eribulin for mTNBC treatment. New treatments resulting in prolonged survival and durable clinical responses would benefit mTNBC patients. Then, we summarize the possible influencing factors of the interaction between tislelizumab and eribulin.

Radiomics Analysis on Noncontrast CT for Distinguishing Hepatic Hemangioma (HH) and Hepatocellular Carcinoma (HCC).

Background: To form a radiomic model on the basis of noncontrast computed tomography (CT) to distinguish hepatic hemangioma (HH) and hepatocellular carcinoma (HCC). Methods: In this retrospective study, a total of 110 patients were reviewed, including 72 HCC and 38 HH. We accomplished feature selection with the least absolute shrinkage and operator (LASSO) and built a radiomics signature. Another improved model (radiomics index) was established using forward conditional multivariate logistic regression. Both models were tested in an internal validation group (38 HCC and 21 HH). Results: The radiomic signature we built including 5 radiomic features demonstrated significant differences between the hepatic HH and HCC groups (P < 0.05). The improved model demonstrated a higher net benefit based on only 2 radiomic features. In the validation group, radiomics signature and radiomics index achieved great diagnostic performance with AUC values of 0.716 (95% confidence interval (CI): 0.581, 0.850) and 0.870 (95% CI: 0.782, 0.957), respectively. Conclusions: Our developed radiomics-based model can successfully distinguish HH and HCC patients, which can help clinical decision-making with lower cost.

The impact of awareness and attitudes towards long-action reversible contraceptives on the intention to use: a survey among youth with unintended pregnancies.

PURPOSE: To understand the associations between awareness, attitudes, and intentions to use long-acting reversible contraceptives (LARCs) among youth seeking induced abortion services in Shanghai, China. MATERIALS AND METHODS: A cross-sectional survey was carried out among 1,215 nulliparous youth with unintented pregnancies in 41 hospitals of Shanghai, China, through a stratified sampling process between January and May 2019. Multivariable logistic regression was used to test the associations between awareness, attitudes and intentions to use LARCs. RESULTS: Around 70% of youth had heard of at least one method of LARCs. About 38% of youth perceived that the copper-bearing intrauterine contraceptive device (Cu-IUD) was safe; the rate was 8% and 7%, respectively, for levonorgestrel-releasing intrauterine system (LNG-IUS) and subdermal implants. Less than 40% of youth thought Cu-IUD was effective in contraception, and it was around 6% for LNG-IUS and subdermal implants. Overall, less than 8% of youth expressed intentions to use LARCs. Positive attitudes towards LARCs were highly associated with the intentions to use LARCs [adjusted Odds Ratio (OR) 3.22, 95% confidence interval (CI) 1.96-5.42, p < 0.001]. CONCLUSIONS: Low awareness and negative attitudes towards LARCs were found in this study, and the negative attitudes towards LARCs could contribute to low intentions to use LARCs among youth who had already experienced unintended pregnancies.

Expression and prognostic analyses of the insulin-like growth factor 2 mRNA binding protein family in human pancreatic cancer.

BACKGROUND: Despite advances in early diagnosis and treatment, cancer remains the leading cause of mortality worldwide. The insulin-like growth factor 2 mRNA binding protein (IGF2BP) family has been reported to be involved in a variety of human malignant tumours. However, little is known about their expression and prognostic value in human pancreatic cancer. Therefore, we performed a detailed cancer versus normal differential analysis. METHODS: The Cancer Genome Atlas (TCGA) and Gene Expression Profiling Interactive Analysis (GEPIA) databases were used to analyse the mRNA expression levels of the IGF2BP family in various cancers, including pancreatic cancer. Then, the LinkedOmics and GEPIA databases were used to assess the relation between the expression levels of IGF2BPs and overall survival (OS). Then, univariate and multivariate Cox regression analyses were performed, and subgroups based on grade and stage were analysed. The signalling pathways associated with IGF2BP2 and IGF2BP3 were then investigated via gene set enrichment analysis (GSEA). RESULTS: IGF2BP2 and IGF2BP3 were associated with each subset of OS based on grade and stage. Further clinical correlation analysis of IGF2BP2 and IGF2BP3 confirmed that IGF2BP2 and IGF2BP3 are fundamental factors in promoting pancreatic cancer progression. CONCLUSION: IGF2BP2 and IGF2BP3 are key factors in promoting the progression of pancreatic cancer and are closely related to overall survival.
