Conclusion: Calculating tumor volume using the Cavalieri method in laryngeal tumors before and after treatment may be useful to optimize the treatment and to minimize the side-effects of radiotherapy.

Purpose: This study aimed to estimate the pre-treatment and post-treatment tumor volumes of the patients to whom radiotherapy or radio-chemotherapy was applied as a treatment using Cavalieri's Principle as a stereological method and to assess tumor regression rates in the patients with Laryngeal Squamous Cell Carcinoma (LSCC) statistically.

Materials And Method: Sixteen patients (eight patients with stage T3 and eight patients with stage T4) diagnosed with LCCC bearing the appropriate characteristics to criteria in the otorhinolaryngology clinic were included. Patients had computerized tomography (CT) scans in the axial plane before treatment and 2 months after the treatment. Pre-treatment and post-treatment tumor volumes on CT images were calculated using Cavalieri's principle as a stereological method and then compared.

Findings: Average tumor volumes in patients with stage T3 before and after treatment were 10.12 ± 3.58 cm(3) and 1.33 ± 1.74 cm(3), respectively (p = 0.008). These volumes were 11.92 ± 4.61 cm(3) and 2.17 ± 2.34 cm(3) (p = 0.008) for patients with stage T4, respectively. Post-treatment tumor volumes were statistically reduced compared to pre-treatment volumes in all stages.

Objective: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest.

Methods: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.

Background And Purpose: Whether differences in the O-methylguanine-DNA methyltransferase () promoter methylation status of glioblastoma (GBM) are reflected in MRI markers remains largely unknown. In this work, we analyze the ADC in the perienhancing infiltration zone of GBM according to the corresponding status by using a novel distance-resolved 3D evaluation.

Materials And Methods: One hundred one patients with wild-type GBM were retrospectively analyzed.

Purpose: Basal Cell Carcinoma (BCC), the most common subtype of non-melanoma skin cancers (NMSC), is prevalent worldwide and poses significant challenges due to their increasing incidence and complex treatment considerations. Existing clinical approaches, such as Mohs micrographic surgery, are time-consuming and labour-intensive, requiring meticulous layer-by-layer excision and examination, which can significantly extend the duration of the procedure. Current optical imaging solutions also lack the necessary spatial resolution, penetration depth, and contrast for effective clinical use.

Background: Patients with Crohn's disease face an elevated risk of colorectal cancer, in part due to underlying chronic inflammation. Biologic therapy is the mainstay of medical treatment; however, the impact of treatment on colorectal cancer-related outcomes remains unclear.

Objective: To investigate the association between prior exposure to biologic treatment and colorectal cancer-related outcomes in patients with underlying Crohn's disease.
