AI Article Synopsis
- The study evaluates the effectiveness of laparoscopic sentinel lymph node (SLN) biopsy in staging patients with localized prostate cancer, emphasizing its role in detecting lymph node metastasis.
- 93 patients participated, achieving a 93.5% detection rate during surgery, with 19 patients confirmed to have lymph node metastases, indicating the method's potential for accurate diagnosis.
- Laparoscopic SLN biopsy allows for targeted removal of affected lymph nodes, reducing the need for extensive surgery while preserving the accuracy of staging, which is crucial for determining prognosis.
Article Abstract
Purpose: Lymph node metastasis is an important prognostic factor in prostate cancer (PC). The aim of this prospective study was to evaluate the accuracy of sentinel lymph node (SLN) biopsy by laparoscopy in staging locoregional patients with clinically localized PC.
Methods: A transrectal ultrasound-guided injection of 0.3 ml/100 MBq (99m)Tc-sulphur rhenium colloid in each prostatic lobe was performed the day before surgery. Detection was performed intraoperatively with a laparoscopic probe (Gamma Sup CLERAD) followed by extensive resection. SLN counts were performed in vivo and confirmed ex vivo. Histological analysis was performed by haematoxylin-phloxine-saffron staining, followed by immunohistochemistry (IHC) if the SLN was free of metastasis.
Results: The study included 93 patients with PC at intermediate or high risk of lymph node metastases. The intraoperative detection rate was 93.5% (87/93). Nineteen patients had lymph node metastases, nine only in SLN. The false-negative rate was 10.5% (2/19). The internal iliac region was the primary metastatic site (43.3%). Metastatic sentinel nodes in the common iliac region beyond the ureteral junction were present in 13.3%. Limited or standard lymph node resection would have ignored 73.2 and 56.6% of lymph node metastases, respectively.
Conclusion: Laparoscopy is suitable for broad identification of SLN metastasis, and targeted resection of these lymph nodes significantly limits the risk of extended surgical resection whilst maintaining the accuracy of the information.

The persistent emergence of COVID-19 variants and recurrent waves of infection worldwide underscores the urgent need for vaccines that effectively reduce viral transmission and prevent infections. Current intramuscular (IM) COVID-19 vaccines inadequately protect the upper respiratory mucosa. In response, we have developed a nonadjuvanted, interferon-armed SARS-CoV-2 fusion protein vaccine with IM priming and intranasal (IN) boost sequential immunization.

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Purpose: Recent advancements in imaging, particularly 18F-fluorodeoxyglucose positron-emission tomography-computed tomography (FDG-PET/CT), have improved the detection of involved lymph nodes, thus influencing staging accuracy and potentially treatment outcomes. This study is a post hoc analysis of the GAZAI trial data to evaluate the impact of FDG-PET/CT versus computed tomography (CT) alone on radiation target volumes for involved-site radiotherapy (IS-RT) in early-stage follicular lymphoma (FL).
Methods: All patients in the GAZAI trial underwent pretherapeutic FDG-PET/CT examinations, which were subject to central quality control.

Background: Preoperative chemoradiotherapy combined with total mesorectal excision (TME) is a standard treatment for locally advanced rectal cancer (LARC). However, lateral pelvic lymph nodes (LPLNs) are often inadequately treated with standard regimens. This study examines the treatment and postoperative outcomes in LARC patients receiving a simultaneous integrated boost (SIB) for LPLNs during long-course chemoradiotherapy.
