Objective:To improve the understanding of pediatric acute promyelocytic leukemia with TTMV::RARA fusion gene positive caused by torque teno mini virus (TTMV).Methods:A retrospective analysis was conducted on the clinical data of a patient with relapsed TTMV::RARA fusion gene-positive acute promyelocytic leukemia who was admitted to Children's Hospital Affiliated to Zhengzhou University in July 2024, and literature review was conducted.Results:The patient was a girl with the age of 5 years and 7 months. She presented with joint pain and fever. Combined with bone marrow cell morphology and whole transcriptome sequencing, she was diagnosed with TTMV::RARA fusion gene-positive acute promyelocytic leukemia. After induction therapy with regimens such as retinoic acid +daunorubicin+cytarabine and retinoic acid+venetoclax+homoharringtonine, the joint pain was relieved, but the primary disease did not improve. Subsequently, there was no regular treatment. One year later, the disease recurred and was complicated with severe infection. Her condition improved following anti-infection and induction therapy.Conclusions:TTMV::RARA fusion gene-positive pediatric acute promyelocytic leukemia is a special type of acute promyelocytic leukemia caused by the insertion of viral sequences from TTMV infection. It is rare in clinical practice and difficult to treat, and the overall prognosis may be poor.

Objective:To systematic review the efficacy and safety of external application of traditional Chinese medicine on treatment of breast cancer related lymphedema.Methods:CNKI, Wanfang Data, VIP, Sino-Med, The Cochrane Library, PubMed, Web of Science were searched for related randomized controlled trials, the retrieval time was from inception to May 25, 2020. Two researchers independently screened and evaluated the included studies. Meta-analysis was performed by RevMan 5.4 software.Results:A total of 16 studies involving 1 315 patients with breast cancer related lymphedema were included, and the methodological quality of the included studies was not high. Compared with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment had advantages in improving the total efficiency( P<0.01) and quality of life( P<0.01), reducing pain( P<0.01) and improving upper limb function( P<0.01), without obvious adverse reactions( P>0.05), but there was no improvement in depression( P>0.05). Compared with conventional treatment, external application of traditional Chinese medicine could improve the total efficiency( P<0.01). Compared with placebo sticker combined with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment can reduce circumference( P<0.05) and reduce pain( P<0.01), without obvious adverse reactions( P>0.05). Conclusions:Available evidence suggests that external application of traditional Chinese medicine may be a potential treatment method for breast cancer related lymphedema. Due to the poor methodological quality of the included studies, high-quality randomized controlled trials are still needed.

Objective:To investigate the implementation procedures and dosimetric verification of the first patient treated with total body irradiation (TBI) based on volumetric modulated arc therapy (VMAT).Methods:Two sets of CT images were acquired under the head-in first and foot-in first to contour the planning target volume (PTV) of the cranial and caudal segments to accomplish the treatment of the whole body length, on which two interrelated plans of 5 subsequent isocenters with a total of 15 VMAT fields were performed to cover all PTVs. The plans were prescribed to ensure 90% PTV dose coverage with a total dose of 12 Gy in 6 fractions. Firstly, a dose optimization was performed on the caudal CT images, then the cranial CT images were optimized based on the dose distribution of the caudal CT images. The evaluation of the final treatment plan was carried out based on a plan sum of both two sets of images. The parameters of PTV and organs at risk (OARs) were measured by dose volume histograms from the accumulated plan. The quality assurance comprised the verification of the VMAT plans for each individual isocenter via Delta4 phantom. The dose distribution in the overlapped region between two adjacent central fields was verified with EBT3 film. The absolute dose at the overlapped region between two images was measured via Pinpoint chamber. In vivo dosimetry on the patient′s skin was monitored by MOSFET dosimeters. The results of planning parameters and treatment duration were analyzed. Results:The mean doses of two segments of PTVs were 12.45 Gy and 12.37 Gy. The mean dose for the lung was 10.8 Gy. The machine unit (MU) and mean treatment delivery time were 2 883 MU and 24.3 min, and the mean total time per fraction was 121 min. The mean 3%/3 mmγ-analysis pass rate for each isocenter VMAT plan was (99.74±0.42)%, and the mean 5%/5 mmγ-analysis pass rate for the overlapped region was (90.11±2.72)%. The average deviation of absolute dose in the overlap region of the caudal and cranial images was (3.6±0.4)%. In vivo measurement of 8 points on the patient showed that the dose of each region was ranged from 1.57 Gy to 2.04 Gy. Conclusion:According to the results of dosimetric verification, TBI based on multi-isocenter VMAT can be applied in clinical practice, which remains to be improved in terms of dose distribution, measurement results and clinical efficiency.
