ASO Visual Abstract: Occult Nodal Disease in Gallbladder Cancer: An International Multi-institutional Analysis and Preoperative Risk Stratification.
Kawashima J, et al
A new international, multi-institutional study investigated the problem of occult nodal disease in gallbladder cancer — lymph node metastases that are present at surgery but not detected by standard preoperative imaging. Researchers pooled data from multiple institutions across different countries to better understand how frequently this hidden spread occurs and which patient or tumor characteristics predict its presence. The study developed a preoperative risk stratification tool designed to help surgeons identify which patients are most likely to harbor undetected lymph node involvement before they undergo an operation. These findings are clinically significant because unrecognized nodal disease can lead to incomplete surgery and poorer outcomes; better preoperative identification may guide more thorough lymph node dissection or influence decisions about neoadjuvant therapy. Overall, this work provides oncology teams with a practical framework to improve surgical planning and potentially extend survival for patients with gallbladder cancer.

Source →Safety and feasibility of combined transanal total mesorectal excision with delayed coloanal anastomosis in high-risk patients with low rectal cancer.
Yue Y, et al
A prospective cohort study published in Techniques in Coloproctology evaluated two surgical strategies for patients with low rectal cancer considered at high risk for complications: transanal total mesorectal excision (taTME) combined with either immediate coloanal anastomosis (ICAA) protected by a temporary stoma, or delayed coloanal anastomosis (DCAA) without a stoma. Among 65 patients analyzed, anastomotic leakage — a serious and potentially life-threatening complication where the bowel connection fails to heal — occurred in 12.1% of patients in the ICAA group but in none of the patients who underwent DCAA. Patients in the DCAA group also showed lower levels of C-reactive protein, a marker of inflammation, in the early postoperative period, suggesting less physiological stress following surgery. Crucially, bowel functional outcomes measured at 3 and 12 months were similar between the two groups, meaning the delayed approach did not compromise long-term quality of life. These findings suggest that delaying the anastomosis after taTME may be a safer alternative for high-risk patients, eliminating both the risk of anastomotic leakage and the burden of stoma-related complications while preserving comparable functional recovery.

Source →Rhabdomyosarcoma of the temporal bone in children - a systematic review.
Gierlotka A, et al
A new systematic review published in the International Journal of Pediatric Otorhinolaryngology examines rhabdomyosarcoma of the temporal bone, a rare and aggressive cancer of the ear region that primarily affects children. Researchers analyzed data from 35 studies encompassing 68 pediatric patients, finding that the most common symptoms included persistent ear discharge in 73% of cases, ear pain in 42%, and facial nerve paralysis in as many as 69% of patients. Imaging consistently revealed a destructive soft-tissue mass in the middle ear and mastoid, frequently extending to the skull base or brain. A critical finding is that this cancer is often mistaken for chronic ear infection, leading to dangerous delays in diagnosis and more advanced disease at the time of correct identification. The standard treatment approach involved a combination of chemotherapy and radiotherapy. The authors urge clinicians to consider this diagnosis in any child with persistent ear symptoms, especially when facial nerve palsy is present or when standard antibiotic treatment fails, as early imaging and tissue biopsy are essential for improving survival outcomes.

Source →Bilayered Porcine Derived Collagen Membranes for Soft Tissue Augmentation in the Oral Cavity.
Munkwitz SE, et al
Researchers investigated whether newly developed porcine-derived collagen membranes (PDCMs) could serve as effective alternatives to autografts for soft tissue augmentation in the oral cavity, a challenging environment due to mechanical stress and salivary enzymes. The study compared two crosslinked PDCMs—one with high crosslinking (HXL) and one with low crosslinking (LXL)—against a widely used noncrosslinked bilayer membrane called Mucograft in a canine model involving 24 beagles observed over 12 weeks. Results showed that all membranes supported successful healing with inflammation decreasing over time, but key differences emerged: the low-crosslinked membrane (LXL) produced superior subepithelial healing at 12 weeks, with more organized collagen and better tissue integration compared to Mucograft. The high- and low-crosslinked membranes also degraded more completely than Mucograft by 8 weeks, suggesting a more physiologically harmonious remodeling process. These findings indicate that LXL membranes offer a promising off-the-shelf alternative to patient-derived tissue grafts, potentially reducing surgical complexity and donor-site morbidity for patients requiring oral soft tissue reconstruction.

Source →Living evidence-informed guideline on the early detection of oral squamous cell carcinoma and potentially malignant disorders: Vital staining adjuncts to determine the need for biopsy, Version 2026 1.0.
Martins-Pfeifer C, et al
A new living evidence-informed guideline published in the Journal of the American Dental Association evaluated the use of vital staining, particularly toluidine blue, as an adjunct tool for the early detection of oral potentially malignant disorders (OPMDs) and oral squamous cell carcinoma. The guideline panel conducted systematic reviews assessing both the benefits and harms of vital staining and considered patient and clinician values, resource requirements, equity, and feasibility. Based on very low certainty evidence, the panel issued a conditional recommendation against using vital staining as a screening or biopsy-decision adjunct in adults, regardless of whether mucosal abnormalities are present. The guideline reaffirms that biopsy remains the gold standard for definitively diagnosing OPMDs and oral cancer, and that clinical oral examination should be performed routinely in all adult patients. These findings are important for dental and medical clinicians because they clarify that widely marketed staining adjuncts do not provide sufficient added value to justify their routine use in early oral cancer detection.
