Non-invasive prenatal testing (NIPT) based on fetal free DNA is a non-invasive technique to screen for common fetal aneuploidies by analyzing cell-free fetal DNA (cffDNA) in the peripheral blood of pregnant women. This technique has opened a new era of prenatal screening for its high safety and reliability. In recent years, it has been shown that NIPT can not only screen for fetal aneuploidies, but may also reveal maternal genomic abnormalities. The incidental detection of maternal tumors has aroused widespread concern in the clinical settings. The aim of this review is to systematically summarize the research progress of NIPT technique in incidental detection of maternal tumors, and to discuss its clinical significance, technical challenges, and future development direction. It has been found that multiple chromosome aneuploidies (MCAs) in NIPT detection is one of the important biomarkers suggesting occult maternal malignant tumors. In this paper, the relevant progress of NIPT technique in the incidental discovery of maternal tumors were reviewed in order to provide a reference for individualized and standardized application of NIPT technique in maternal health monitoring.

OBJECTIVE: Angiogenesis is a critical target for hepatocellular carcinoma (HCC) treatment. The previous studies indicated that Jiedu Fang (JDF) could inhibit hypoxia-induced angiogenesis through interleukin-8 (IL-8). Therefore, the present study further explores the mechanisms behind JDF's inhibition of HCC angiogenesis. METHODS: Angiogenesis was assessed with the capillary-like tube formation assay in vitro and the matrigel plug angiogenesis assay in vivo. A liver cancer-related gene set and genes associated with angiogenesis and the hypoxic microenvironment were analyzed using a bioinformatics platform. Real-time reverse transcription-polymerase chain reaction and Western blotting assays were used to assess the targeted mRNA and protein levels, respectively. The Transwell assay was used to assess the migration and invasion potential of EA.hy 926 cells. The orthotopic tumor xenograft model was established, and immunohistochemistry and immunofluorescence assays were used to detect cluster of differentiation 31 and angiopoietin 2 expression, while an enzyme-linked immunosorbent assay was used to detect vascular endothelial growth factor and IL-8 protein levels. RESULTS: In vitro and in vivo assays showed that IL-8 promoted angiogenesis, and JDF could antagonize this effect. Bioinformatics analysis indicated that aurora kinase A (Aurora A) was an important candidate, which can promote IL-8 expression through activation of signal transducer and activator of transcription 3 (STAT3). The overexpression of Aurora A increased IL-8 secretion and promoted HCC migration, invasion, and angiogenesis, which was partly inhibited by JDF. Such effects were validated by in vivo assays. Further validation using the STAT3 inhibitor S3I-201 demonstrated that STAT3 was regulated by Aurora A. CONCLUSION JDF exhibits efficacy in reducing hypoxia-induced angiogenesis in HCC through a mechanism involving the Aurora A/STAT3/IL-8 signaling pathway. Therefore, JDF holds promise as a potential therapeutic approach for targeting HCC angiogenesis. Please cite this article as: Zhong MF, Luo YJ, Guo YY, Xiang S, Lin WF.

Glioma, the most prevalent primary tumor of the central nervous system (CNS), is also the most lethal primary malignant tumor. Currently, there are limited chemotherapeutics available for glioma treatment, necessitating further research to identify and develop new chemotherapeutic agents. A significant approach to discovering anti-glioma drugs involves isolating antitumor active ingredients from natural products (NPs) and optimizing their structures. Additionally, targeted drug delivery systems (TDDSs) are employed to enhance drug solubility and stability and overcome the blood-brain barrier (BBB). TDDSs can penetrate deep into the brain, increase drug concentration and retention time in the CNS, and improve the targeting efficiency of NPs, thereby reducing adverse effects and enhancing anti-glioma efficacy. This paper reviews the research progress of anti-glioma activities of NPs, including alkaloids, polyphenols, flavonoids, terpenoids, saponins, quinones, and their synthetic derivatives over the past decade. The review also summarizes anti-glioma mechanisms, such as suppression of related protein expression, regulation of reactive oxygen species (ROS) levels, control of apoptosis signaling pathways, reduction of matrix metalloproteinases (MMPs) expression, blocking of vascular endothelial growth factor (VEGF), and reversal of immunosuppression. Furthermore, the functions and advantages of NP-based TDDSs in anti-glioma therapy are examined. The key information presented in this review will be valuable for the research and development of NP-based anti-glioma drugs and related TDDSs.

Both carcinoembryonic antigen and CA19-9 are considered as predictive markers of intestinal cancer recurrence and metastasis.In addition,CA19-9 elevation is considered as a predictive marker of connective tissue disease-related interstitial lung disease.The incidence of oxaliplatin and capecitabine-associated interstitial lung disease is low,and there is no report about CA19-9 as a predictive marker of oxaliplatin and capecitabine-associated interstitial lung disease.This paper reports a case of interstitial lung disease with CA19-9 elevation caused by oxaliplatin and capecitabine adjuvant therapy for ileocecal carcinoma.The change trend of serum carcinoembryonic antigen in this patient was consistent with tumor recurrence and metastasis,and that of serum CA19-9 was consistent with the severity of interstitial lung disease.Therefore,CA19-9 elevation after intestinal cancer surgery does not necessarily indicate the tumor recurrence and metastasis,and attention should be paid to the possibility of oxaliplatin and capecitabine-associated interstitial lung disease.

OBJECTIVE: To evaluate the effectiveness of the innervated medial plantar flap for reconstructing soft tissue defects, particularly in the weight-bearing zone, after resection of foot tumors. METHODS: A retrospective analysis was conducted on 12 patients with malignant skin and soft tissue tumors of the foot treated between October 2023 and December 2024. The cohort included 8 males and 4 females, aged 42-67 years (mean, 57.5 years). Tumor types comprised malignant melanoma (5 cases), squamous cell carcinoma (4 cases), arsenical keratosis (2 cases), and tumor-induced osteomalacia (1 case). Soft tissue defects located in the heel weight-bearing region in 10 cases and non-weight-bearing ankle region in 2 cases, with defect sizes ranging from 4.0 cm×3.0 cm to 6.0 cm×4.0 cm. Preoperative photon-counting CT angiography (PC-CTA) was performed to assess the medial plantar artery and its perforators. All patients underwent radical tumor resection with confirmed negative margins. The resulting defects were reconstructed using a innervated medial plantar flap incorporating sensory branches of the medial plantar nerve. The flap donor site was covered with a split-thickness skin graft harvested from the ipsilateral inguinal region. RESULTS: The operation was successfully completed in all 12 patients. All flaps survived completely without vascular compromise, partial necrosis, or total loss. Incisions healed primarily without dehiscence or infection. Minor skin graft necrosis occurred at the donor site in 3 patients, which healed within 2-3 weeks with routine dressing changes. No donor site complication (e.g., tendon or nerve injury) occurred. Patients were followed up 2-16 months (mean, 10.3 months). At last follow-up, there was no tumor recurrence. Flaps exhibited good color and texture match with surrounding tissue, restored sensation, and all feet achieved normal weight-bearing activity. CONCLUSION The innervated medial plantar flap, precisely designed based on PC-CTA localization, provides reliable blood supply and effective sensory restoration. It is an ideal method for reconstructing soft tissue defects after foot tumor resection, especially in the heel weight-bearing region.

OBJECTIVE: To compare the effectiveness of single-stage vascularized lymph node transfer (VLNT) combined with lymphaticovenular anastomosis (LVA) and liposuction (LS) (3L) versus LVA combined with LS (2L) for the treatment of moderate-to-late stage upper limb lymphedema following breast cancer surgery. METHODS: A retrospective analysis was conducted on the clinical data of 16 patients with moderate-to-late stage upper limb lymphedema after breast cancer surgery, treated between June 2022 and June 2024, who met the selection criteria. Patients were divided into 3L group (n=7) and 2L group (n=9) based on the surgical approach. There was no significant difference (P>0.05) in baseline data between the groups, including age, body mass index, duration of edema, volume of liposuction, International Society of Lymphology (ISL) stage, preoperative affected limb volume, preoperative circumferences of the affected limb at 12 levels (from 4 cm distal to the wrist to 42 cm proximal to the wrist), preoperative Lymphoedema Quality of Life (LYMQoL) score, and frequency of cellulitis episodes. The 2L group underwent LS on the upper arm and proximal forearm and LVA on the middle and distal forearm. The 3L group received additional VLNT in the axilla, with the groin serving as the donor site. Outcomes were assessed included the change in affected limb volume at 12 months postoperatively, and comparisons of limb circumferences, LYMQoL score, and frequency of cellulitis episodes between preoperative and 12-month postoperative. Ultrasound evaluation was performed at 12 months in the 3L group to assess lymph node viability. RESULTS: Both groups were followed up 12-20 months, with an average of 15.13 months. There was no significant difference in the follow-up time between the groups (t=-1.115, P=0.284). All surgical incisions healed by first intention. No adverse events, such as flap infection or necrosis, occurred in the 3L group. At 12 months after operation, ultrasound confirmed good viability of the transferred lymph nodes in the 3L group. Palpation revealed significant improvement in skin fibrosis and improved skin softness in both groups. Affected limb volume significantly decreased in both groups postoperatively (P<0.05). The reduction in limb volume significantly greater in the 3L group compared to the 2L group (P<0.05). Circumferences at all 12 measured levels significantly decreased in both groups compared to preoperative values (P<0.05). The reduction in circumference at all 12 levels was better in the 3L group than in the 2L group, with significant differences observed at 7 levels (8, 12, 16, 30, 34, 38, and 42 cm) proximal to the wrist (P<0.05). Both groups showed significant improvement in the frequency of cellulitis episodes and LYMQoL scores postoperatively (P<0.05). While the improvement in LYMQoL scores at 12 months did not differ significantly between groups (P>0.05), the reduction in cellulitis episodes was significantly greater in the 3L group compared to the 2L group (P<0.05). CONCLUSION The combination of VLNT+LVA+LS provides more durable and comprehensive outcomes for moderate-to-late stage upper limb lymphedema after breast cancer surgery compared to LVA+LS, offering an improved therapeutic solution for patients.

OBJECTIVE: To explore the technical key points and effectiveness of the facial artery perforator myomucosal flap (FAPMF) in repairing oral and perioral tissue defects. METHODS: Between June 2023 and December 2024, 8 patients with oral and perioral tissue defects were repaired with the FAPMF. There were 4 males and 4 females, with an average age of 57.6 years (range, 45-72 years). Among them, 4 cases had floor-of-mouth defects and 3 cases had buccal mucosa defects remaining after squamous cell carcinoma resection, and 1 case had lower lip defect caused by trauma. The size of tissue defects ranged from 4.5 cm×3.0 cm to 6.0 cm×5.0 cm. The preoperative mouth opening was (39.55±1.88) mm, and the preoperative swallowing score of the University of Washington Quality of Life Questionnaire (UW-QOL) was 64.64±8.47. Preoperatively, CT angiography and Doppler ultrasound were used to locate the perforator vessels. A myomucosal flap pedicled with the perioral perforators of the facial artery was designed, with the harvesting size ranging from 4.0 cm×2.5 cm to 6.5 cm×4.0 cm. The length of the vascular pedicle was 4.2-6.8 cm (mean, 5.2 cm). Postoperatively, FAPMF survival, complications, and functional recovery were observed. RESULTS: All 8 surgeries were successfully completed without conversion to other repair methods or complications such as facial nerve injury. The total operation time ranged from 110 to 180 minutes, with an average of 142.5 minutes; among this, the harvesting time of the FAPMF ranged from 35 to 65 minutes, with an average of 48.7 minutes. The intraoperative blood loss was 50-150 mL, with an average of 85.6 mL. All FAPMFs survived completely. One patient developed venous reflux disorder at 24 hours after operation, which relieved after conservative treatment. All patients were followed up 7-16 months (mean, 12.4 months). All FAPMFs achieved complete epithelialization at 3 months after operation, showing a similar soft texture to the surrounding mucosa. At 7 months after operation, the mouth opening was (39.11±1.79) mm, slightly lower than preoperative level, but the difference was not significant (P>0.05). The swallowing score of the UW-QOL was 63.78±8.31, which was significantly lower than preoperative score (P<0.05). The visual analogue scale (VAS) score for patient satisfaction was 7-10, with an average of 8.9. CONCLUSION The FAPMF has advantages such as reliable blood supply, high mucosal matching degree, and concealed donor site, making it an ideal option for repairing small and medium-sized oral and perioral tissue defects.

OBJECTIVE: To explore the feasibility and effectiveness of repairing surgical defect in pharyngo-laryngeal malignant tumor with free rectus femoris flap. METHODS: The clinical data of 34 patients with surgical defects in pharyngo-laryngeal malignant tumor who met the selection criteria between July 2014 and August 2024 were retrospectively analyzed. There were 25 males and 9 females, aged 25-82 years, with a median age of 54 years. The disease duration ranged from 2 months to 2 years, with a median of 7 months. The tumor locations included the oropharynx, hypopharynx, cervical esophagus, and larynx. Pathological types included squamous cell carcinoma (29 cases), myoepithelial carcinoma (2 cases), adenoid cystic carcinoma (1 case), and diffuse large B-cell lymphoma (2 cases). TNM staging: 16 cases of T ₄N ₁M ₀, 3 cases of T ₄N ₂M ₀, 3 cases of T ₄N ₀M ₀, 10 cases of T ₃N ₁M ₀, and 2 cases of T ₃N ₀M ₀. The 2017 American Joint Committee on Cancer (AJCC) staging was stage Ⅲ in 2 cases and stage Ⅳ in 32 cases. The blood supply of the proximal rectus femoris muscle was observed by enhanced CT of the lower limb vessels before operation, and the surgical defects ranged from 3.0 cm×2.0 cm to 12.0 cm×8.5 cm. The blood supply and perforators of rectus femoris muscle were explored during operation, and the free rectus femoris flap pedicled with the direct vascular stem of rectus femoris muscle was used to repair the defect. For the patients with pharyngeal fistula or obvious neck swelling after operation, the blood supply of the flap was analyzed by vascular enhanced CT to determine the corresponding strategies of nutritional support, anti-infection, dressing change and drainage. Radiotherapy and chemotherapy were supplemented in 27 patients with lymph node metastasis after operation. RESULTS: All the 34 patients were followed up 1-10 years, with an average of 3 years. The flap was found to be necrotic by fibrolaryngoscopy at 1 week after operation in 2 cases, and the incision healed after dressing change and nutritional support, and no reoperation was performed. The flap was in good condition at 1 week after operation in 4 cases, and the signs of gradual necrosis of the flap were found within 1 month after operation, of which 2 cases were healed after dressing change, 1 case was removed the necrotic tissue by reoperation, and 1 case was healed after pectoralis major myocutaneous flap was used to repair the pharyngeal tissue defect. The flaps survived in 28 cases, including 4 cases of pharyngeal fistula, which healed by dressing change. Twenty-two cases achieved satisfactory results in swallowing or phonation. Two patients with total laryngectomy and voice reconstruction underwent reoperation to seal the voice tube because of postoperative aspiration. During the follow-up, 1 case had tracheal stomal recurrence, 2 cases had bone metastasis, and 1 case had bone and lung metastasis. CONCLUSION The free rectus femoris flap has good flexibility, the volume of the flap is easy to adjust, and the incision of the donor site is concealed, which is expected to become a new choice for the repair of the surgical defect in pharyngo-laryngeal malignant tumor.

Objective To precisely identify the para-Bombay blood types in cancer patients at our hospital, establish a robust system for the identification of challenging blood types in our laboratory, and provide a foundation for precise transfusion practices. Methods We retrospectively analyzed the blood type results of 91 874 cancer patients from January 1, 2019, to December 31, 2023. Conventional serological methods were used to screen for blood types, and suspected para-Bombay blood types were identified. Further analysis was performed using Pacific Biosciences (PacBio) single-molecule real-time sequencing and Sanger sequencing was used to determine the genotypes of the ABO, FUT1, and FUT2 genes. Results Eight cases of para-Bombay blood type were confirmed through serological and molecular biological methods. The FUT1 genotypes identified were: 5 cases of h1h1 (homozygous mutation 551_552delAG) and 3 cases of h1h2 (compound heterozygous mutations of 551_552delAG and 880_882delTT). The FUT2 genotypes identified were: 2 cases of Se³⁵⁷/Se^{357, 716} and 4 cases of Se³⁵⁷/Se³⁵⁷. Additionally, one sample revealed a novel heterozygous mutation, 818C>T, in exon 7 of the ABO gene, which was confirmed by PacBio sequencing to be located on the O haplotype. Conclusion PacBio sequencing technology demonstrates significant advantages in analyzing the haplotypes of para-Bombay blood type genes. This approach supports the establishment of a robust system for the identification of challenging blood types and provides novel evidence for precise transfusion practices in cancer patients.

Objective To investigate the causal relationship between serum total bile acid (TBA) levels and gastric cancer (GC) using regression discontinuity design (RDD). Methods A total of 1244 GC patients and 1333 healthy controls were included in the study. Demographic characteristics, gallbladder disease history, tumor markers, and serum TBA levels were collected from both groups. Logistic regression was used to construct a risk prediction model to estimate the risk of GC. RDD was employed with serum TBA as the grouping variable and the individual risk of developing GC as the outcome variable. Results The predictive factors in the GC risk prediction model included age, sex, body mass index(BMI), serum TBA, carcinoembryoniv antigen(CEA), alpha fetoprotein(AFP), carbohydrate antigen 199(CA199), and CA125. Serum TBA was identified as an independent risk factor for GC (OR=1.054, 95% CI: 1.030 to 1.079). RDD analysis indicated that when serum TBA levels reached 8 μmol/L, the probability of developing GC increased sharply by 23.7%. The breakpoint remained statistically significant following validity and robustness assessments. Conclusion The study demonstrates a positive causal relationship between serum TBA levels and GC, when the serum TBA level reaches 8 μmol/L, the risk of an individual developing GC increases sharply.
