Objective:To investigate the therapeutic efficacy of venetoclax combined with avapritinib in treatment of refractory/relapsed acute myeloid leukemia (AML) with KIT gene mutation.Methods:The clinical data of 2 AML patients with KIT gene mutation who received venetoclax combined with avapritinib admitted to Canglang Hospital of Suzhou in October 2022 and November 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:Both patients with high-risk relapsed/refractory AML and KIT gene mutation were females; the one was 53 years and the other was 17 years. Case 1 was diagnosed with AML-M 2, and genetic testing revealed positive mutations in ASXL1, KIT, and RUNX1. The patient relapsed after transplantation and then was treated with venetoclax combined with avapritinib achieving morphologic leukemia-free status (MLFS). Case 2 was diagnosed with AML, and RUNX1-RUNX1T1 (AML1-ETO) fusion gene and KIT and DX15 gene mutations were detected. The patient was treated with venetoclax combined with avapritinib regimen after relapse, and the treatment regimen significantly reduced the tumor load. Complete remission was achieved after bridging to allogeneic hematopoietic stem cell transplantation. Conclusions:AML with KIT gene mutation is heterogeneous and some patients are difficult to treat with very poor prognosis. Bridging (secondary) hematopoietic stem cell transplantation can be the better treatment choice for relapsed patients achieving MLFS or complete remission after venetoclax combined with avapritinib treatment regimen.

Objective:To investigate the value of radiomics signatures based on 18F-FDG PET/CT for predicting molecular classification and Ki-67 expression of breast cancer. Methods:A total of 134 female patients ((55.4±13.3) years) who underwent 18F-FDG PET/CT examination and were diagnosed with breast cancer by pathology in the First Affiliated Hospital of Soochow University from April 2016 to May 2023 were retrospectively enrolled. LIFEx software was used to extract radiomics features and the least absolute shrinkage and selection operator (LASSO) algorithm and independent-sample t test were used to screen potentially meaningful features and calculate the radiomics score, which were considered as radiomics models. Clinical characteristics were selected by supervised logistic regression and clinical models were established. Radiomics features and clinical characteristics were incorporated to logistic regression analysis to establish combined models. ROC curves were drawn and the differences among AUCs were analyzed by Delong test. Results:Among 134 patients, 22 were with triple negative breast cancer (TNBC), 47 were human epidermal growth factor receptor 2 (HER2) over-expression type, 37 were Luminal A type and the rest 28 were Luminal B type. The expression of Ki-67 was high in 85 patients, and was low in the rest 49 patients. The AUCs (95% CI) of the combined models for predicting TNBC, HER2 overexpression type, Luminal A type and Ki-67 expression were 0.843(0.770-0.900), 0.808(0.723-0.876), 0.825(0.711-0.908) and 0.836(0.762-0.894), respectively, which were higher than those of clinical models ( z values: 1.97-3.06, all P<0.05). Conclusion:The predictive model combining radiomics signatures based on 18F-FDG PET/CT and clinical characteristics can well predict the molecular classification and Ki-67 expression level of breast cancer.

Objective:To investigate the effect of autologous fat grafting in hand rejuvenation and to provide effective clinical treatment for the aging hand.Methods:A total of 52 patients received autologous fat grafting in hand. Fat was collected by liposuction from the abdomen or thigh regions utilizing the superwet technique. The harvested fat was washed and injected to the dorsal hand. Standardized photographs were taken before and after the operation, and the patients＇ satisfaction was evaluated.Results:Picture scores between preoperative and postoperative had statistically significant differences ( P<0.01). The majority of patients (75%) were satisfied with their results. All patients were followed up for 6 months with no infection, fat liquefaction, cysts and other complications occurred. Conclusions:This study provides the clinical basis for fat grafting in hand rejuvenation with high satisfactory rates.

Objective:To prospectively guide the change of chemotherapy regimen in mouse 5-fluorouracil (5-FU) resistance subcutaneous xenograft tumor model derived from gastric cancer patients by the early changes of MRI apparent diffusion coefficient (ADC), and to compare the difference of tumor load between ADC guided dressing change group and volume guided dressing change group.Methods:From January to June 2020, thirty patient-derived xenografts mouse models were established using 5-FU resistant gastric cancer cells coming from patients, and were randomly divided into experimental group and control group by AdaBoost algorithm, with 15 mice in each group. On the 26th day after transplantation, all mice began chemotherapy with 5-FU as the first-line chemotherapy drug, and underwent MR examination once every two days, including T 2WI and diffusion weighted imaging (DWI). Volumes of tumors were measured using an open-source software ITK-SNAP and values of ADC were measured on ADC maps. According to the change rate of tumor ADC value in the experimental group and the tumor volume growth rate in the control group, the replacement time of chemotherapy drugs was determined, and 5-FU was replaced by paclitaxel. The end point of the experiment was the day that the mice entered the cachexia state. Independent-sample t test was used to compare the difference of tumor load between the two groups. Results:After 5-FU treatment, the ADC value of the two groups both increased. The ADC value began to decline on the 4th day after chemotherapy, and the experimental group continued chemotherapy with paclitaxel instead of 5-FU at this time point. The tumor volume growth rate of the control group increased significantly on the 6th day after chemotherapy (from 8.6% to 16.1%), and the control group used paclitaxel instead of 5-FU chemotherapy at this time point. The observed end point was on the 18th day after chemotherapy. The tumor load of the experimental group [(1.82±0.09) cm 3] was lower than that of the control group [(2.01±0.09) cm 3], and the difference was statistically significant ( t=2.25, P=0.033). On the 16th day after chemotherapy in the experimental group and the 18th day after chemotherapy in the control group, the time of paclitaxel administration in both groups was 12 days. The tumor load in the experimental group [(1.61±0.12) cm 3] was also lower than that in the control group [(2.01±0.09) cm 3], and the difference was statistically significant ( t=2.03, P=0.040). Conclusions:For the subcutaneous transplantation model of 5-FU resistant gastric cancer mice, according to the early changes of tumor ADC value after chemotherapy, the replacement of chemotherapy drugs can obtain a lower tumor load, suggesting that it is a feasible method to optimize the chemotherapy regimen.

Background/Aims: Existing hepatocellular carcinoma (HCC) prediction models are derived mainly from pretreatment or early on-treatment parameters. We reassessed the dynamic changes in the performance of 17 HCC models in patients with chronic hepatitis B (CHB) during long-term antiviral therapy (AVT). Methods: Among 987 CHB patients administered long-term entecavir therapy, 660 patients had 8 years of follow-up data. Model scores were calculated using on-treatment values at 2.5, 3, 3.5, 4, 4.5, and 5 years of AVT to predict threeyear HCC occurrence. Model performance was assessed with the area under the receiver operating curve (AUROC). The original model cutoffs to distinguish different levels of HCC risk were evaluated by the log-rank test. Results: The AUROCs of the 17 HCC models varied from 0.51 to 0.78 when using on-treatment scores from years 2.5 to 5. Models with a cirrhosis variable showed numerically higher AUROCs (pooled at 0.65–0.73 for treated, untreated, or mixed treatment models) than models without (treated or mixed models: 0.61–0.68; untreated models: 0.51–0.59). Stratification into low, intermediate, and high-risk levels using the original cutoff values could no longer reflect the true HCC incidence using scores after 3.5 years of AVT for models without cirrhosis and after 4 years of AVT for models with cirrhosis. Conclusions The performance of existing HCC prediction models, especially models without the cirrhosis variable, decreased in CHB patients on long-term AVT. The optimization of existing models or the development of novel models for better HCC prediction during long-term AVT is warranted.

Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancer, with a 5-year survival rate of less than 15%-19%, and more than 80% of the patients with lung cancer have progressed to advanced stage (Stage IIIb-IV) when they are clearly diagnosed. The comprehensive treatment mainly based on chemotherapy as the primary form is now considered as the major therapy method for advanced NSCLC without actionable driver gene mutations. Pemetrexed plus platinum doublet as well as single-agent pemetrexed are respectively the first-line major regimens recommended by guidelines and the second-line optional regimens. Yet the third-line treatment or beyond in advanced NSCLC is not evidence-based but conducted based on patients' previous medications, which is one of the most commonly used clinical methods. As pemetrexed is a multi-target chemotherapy drug with high efficiency but low toxicity, pemetrexed re-challenge strategy in advanced NSCLC is also a reasonable choice. We report one effective individual case that adopted pemetrexed re-challenge strategy in advanced NSCLC for three times, and at the same time conduct the relevant literature review.

Objective: To observe the effects of Chinese herbalprescription Tizhi-Pingtiao Powder (TP) based on Five-Yun Six-Qi theory to treat hyperlipidemia (HLP). Methods: This study included 641 HLP patients from Constitution medicine clinic in Dongzhimen hospital from January 2015 to November 2017. The embryonic period’s (ten months) Five-Yun Six-Qi endowments of the enrolled patients were analyzed and TP were prescribedaccordingly, in the absent of lipid-lowering drugs. The curative effect was observed after three months’ TP treatment and reviewed ofeach 3 months, and long-term effects will be observed for 1 year,either take the priscription or not. Curative effect is based on blood lipids maintain normal as well as constitution improved while stopped lipid-lowering drugs. Results: Among the 641 patients who met the inclusion criteria, 379 patients take on complete, and 300 patients (79.2%) were clinically cured (with blood lipid decreased to normal, overall constitution and complication condition improved), 375 patients (99.0%) were completely cured. Among 262 patients without dietary restriction, 143 patients (54.6%) were clinically cured, 240 patients (91.6%) were completely cured. Long-term effects showed that 210 patients stopped the TP after 3 months' treatment, the recurrence rate at the end of the 3rd month, 6th month and 12th month in the patients who were on complete dietary restriction were 4.1%, 48.8% and 76.9%, while the recurrence rate in the patients who had not implemented dietary restriction were 37.1%, 70.8%, 89.9%. A total of 115 patients continued the TP for the other 12 months, the recurrence rate at the end of 3rd month, 6th month and 12th month in the patients who were on complete dietary restriction were 2.5%, 4.8% and 6.0%, while the recurrence rate in the patients who had not implemented dietary restriction were 6.5%, 16.1%, 29.0%. The difference between the four groups was significant. All recrudescent patients could gain recovery in a month after re-taking the herbs. Conclusions Chinese herbal priscription TP combined with dietary modification showed long term effect for HLP and improve the constitution comprehensively.

Patients with cancer are at increased risk of severe infections. From a cohort including 3060 patients with confirmed COVID-19, 109 (3.4%) cancer patients were included in this study. Among them, 23 (21.1%) patients died in the hospital. Cancer patients, especially those with hematological malignancies (41.6%), urinary carcinoma (35.7%), malignancies of the digestive system (33.3%), gynecological malignancies (20%), and lung cancer (14.3%), had a much higher mortality than patients without cancer. A total of 19 (17.4%) cancer patients were infected in the hospital. The clinical characteristics of deceased cancer patients were compared with those of recovered cancer patients. Multivariate Cox regression analysis indicated that a Nutritional Risk Screening (NRS2002) score ⩾ 3 (adjusted hazard ratio (HR) 11.00; 95% confidence interval (CI) 4.60-26.32; P < 0.001), high-risk type (adjusted HR 18.81; 95% CI 4.21-83.93; P < 0.001), tumor stage IV (adjusted HR 4.26; 95% CI 2.34-7.75; P < 0.001), and recent adjuvant therapy (< 1 month) (adjusted HR 3.16; 95% CI 1.75-5.70; P < 0.01) were independent risk factors for in-hospital death after adjusting for age, comorbidities, D-dimer, and lymphocyte count. In conclusion, cancer patients showed a higher risk of COVID-19 infection with a poorer prognosis than patients without cancer. Cancer patients with high-risk tumor, NRS2002 score ⩾ 3, advanced tumor stage, and recent adjuvant therapy (< 1 month) may have high risk of mortality.
