Purpose:
Cancer poses a significant global health challenge, demanding precise genomic testing for individualized treatment strategies. Targeted-panel sequencing (TPS) has improved personalized oncology but often lacks comprehensive coverage of crucial cancer alterations. Whole-genome sequencing (WGS) addresses this gap, offering extensive genomic testing. This study demonstrates the medical potential of WGS.
Materials and Methods:
This study evaluates target-enhanced WGS (TE-WGS), a clinical-grade WGS method sequencing both cancer and matched normal tissues. Forty-nine patients with various solid cancer types underwent both TE-WGS and TruSight Oncology 500 (TSO500), one of the mainstream TPS approaches.
Results:
TE-WGS detected all variants reported by TSO500 (100%, 498/498). A high correlation in variant allele fractions was observed between TE-WGS and TSO500 (r=0.978). Notably, 223 variants (44.8%) within the common set were discerned exclusively by TE-WGS in peripheral blood, suggesting their germline origin. Conversely, the remaining subset of 275 variants (55.2%) were not detected in peripheral blood using the TE-WGS, signifying them as bona fide somatic variants. Further, TE-WGS provided accurate copy number profiles, fusion genes, microsatellite instability, and homologous recombination deficiency scores, which were essential for clinical decision-making.
Conclusion
TE-WGS is a comprehensive approach in personalized oncology, matching TSO500’s key biomarker detection capabilities. It uniquely identifies germline variants and genomic instability markers, offering additional clinical actions. Its adaptability and cost-effectiveness underscore its clinical utility, making TE-WGS a valuable tool in personalized cancer treatment.

Annals of Surgical Treatment and Research 2025;108(5):302-309
Purpose:
Pathologic lesions may occur in an axillary accessory breast (AAB). This study aimed to evaluate the characteristics of tumors arising from AABs and to recommend appropriate treatment.
Methods:
This retrospective study involved 3,544 women (18–65 years old) with AAB at Damsoyu Hospital in Korea from 2014 to 2023. The patients were divided into an AAB with benign tumors (TAAB) group and an AAB without tumors (AAB) group, and the tumors’ pathologies were reviewed. A core biopsy was performed on tumors with possible malignancy identified by preoperative ultrasonography. All patients underwent complete excision of accessory mammary gland (AMG) tissue, including tumors. The postoperative results were checked 6 months after surgery.
Results:
Fifty-two out of 3,554 patients had tumors confirmed by preoperative ultrasonography. Preoperative core biopsies were performed on 11 patients. Two patients had malignant tumors (invasive ductal carcinoma) identified by core biopsy.Fifty patients had benign tumors identified by postoperative pathological analysis (46 fibroadenomas, 2 fibrocystic changes, and 2 sclerosing adenoses). Carcinoma in situ was confirmed in 2 patients using postoperative pathological analysis. No patients in either group developed tumors in the axilla during the follow-up period. All patients were satisfied with the axillary pain relief and the disappearance of bulging lesions.
Conclusion
We recommend a core biopsy if preoperative ultrasonography indicates a possibly malignant tumor. AAB patients may experience tumors, pain, and bulging appearance of an AMG; thus, complete AMG excision is necessary.

Asthma is a chronic inflammatory disorder of the lungs that results in airway inflammation and narrowing. BS012 is an herbal remedy containing Asarum sieboldii, Platycodon grandiflorum, and Cinnamomum cassia extracts. To elucidate the anti-asthma effect of BS012, this study analyzed the immune response, respiratory protection, and changes in metabolic mechanisms in an ovalbumininduced allergic asthma mouse model. Female BALB/c mice were exposed to ovalbumin to induce allergic asthma. Bronchoalveolar lavage fluid and plasma were analyzed for interleukin and immunoglobulin E levels. Histological analyses of the lungs were performed to measure morphological changes. Apoptosis-related mediators were assayed by western blotting. Plasma and lung tissue metabolomic analyses were performed to investigate the metabolic changes. A T-helper-2-like differentiated cell model was used to identify the active components of BS012. BS012 treatment improved inflammatory cell infiltration, mucus production, and goblet cell hyperplasia in lung tissues. BS012 also significantly downregulated ovalbumin-specific immunoglobulin E in plasma and T-helper-2-specific cytokines, interleukin-4 and -5, in bronchoalveolar lavage fluid. The lungs of ovalbumin-inhaled mice exhibited nerve growth factor-mediated apoptotic protein expression, which was significantly attenuated by BS012 treatment. Ovalbumin-induced abnormalities in amino acid and lipid metabolism were improved by BS012 in correlation with its anti-inflammatory properties and normalization of energy metabolism. Additionally, the differentiated cell model revealed that N-isobutyl-dodecatetraenamide is an active component that contributes to the anti-allergic properties of BS012. The current findings demonstrate the anti-allergic and respiratory protective functions of BS012 against allergic asthma, which can be considered a therapeutic candidate.

10.Characteristics of pantaloon inguinal hernia and evaluation of added laparoscopic iliopubic tract repair to transabdominal preperitoneal hernioplasty: a retrospective observational study
Annals of Surgical Treatment and Research 2024;106(6):361-368
Purpose:
Pantaloon hernia (PH), defined as concurrent ipsilateral direct and indirect inguinal hernias, is known for its high postoperative recurrence rate. This study retrospectively investigated the characteristics of PHs and evaluated the safety and efficacy of incorporating laparoscopic iliopubic tract repair (IPTR) into transabdominal preperitoneal (TAPP) hernioplasty.
Methods:
A total of 3,355 patients who underwent TAPP hernioplasty for groin hernias between October 2014 and December 2021 were analyzed. These patients were divided into 2 groups: PH (97 patients) and non-PH (3,258 patients). The PH group was further subdivided based on the surgical technique used: TAPP hernioplasty without IPTR (TAPP group, 39 patients) and TAPP hernioplasty with IPTR for defect closure (TAPP + IPTR group, 58 patients).
Results:
The study included 93 male and 4 female patients with PH. Patients with PH were generally older and predominantly male compared to the non-PH group. The recurrence rate in the PH group was notably higher than in the non-PH group (2.1% [2 of 97] vs. 0.2% [6 of 3,258], respectively; P = 0.007). Among the PH group, reoperations were more frequent in the TAPP group compared to the TAPP + IPTR group (10.3% [4 of 39] vs. 0% [0 of 58], respectively; P = 0.048). The reasons for reoperation in the PH group included recurrences (2 patients), mesh bulge (1 patient), and chronic seroma (1 patient).
Conclusion
TAPP + IPTR hernioplasty is an acceptable approach in PH treatment, reducing reoperation.
