This study examines sentinel lymph node tissue from early stage cervical cancer patients treated with radical hysterectomy and removal of pelvic sentinel lymph nodes (SLN). SLNs are tested for the presence of human papilloma virus (HPV), and results are compared to the HPV-type found in the patients cervical tissue. We hereby examine whether pathologic status of SLNs in patients with early-stage cervical cancer correlates to the HPV status in the SLNs. By means of an up to 5-years follow-up period, we furthermore examine whether cervical cancer recurrence correlates to the histopathologic status of the SLNs and/or the SLN HPV status. This will contribute to the clarification on whether HPV status of the SLNs plays a crucial role for predicting LN metastasis of cervical cancer and also, whether the HPV status in SLNs may have a clinical value as a prognostic factor for disease recurrence in cervical cancer patients and perhaps even a better clinical value than SLN mapping.
Eccrine porocarcinoma (EPC) is a slow-growing carcinoma arising from the eccrine sweat glands. Based on its clinical presentation it can be confused with malignant and benign skin lesions, both. Histological examination is essential to formulate a correct diagnosis. Surgical excision with clear margins is the standard therapeutic approach while the role of sentinel lymph node biopsy (SNLB) remains controversial. The Authors report two cases of EPC of the lower limbs occurred in two women. Patients were treated by wide surgical excision of the lesion and SNLB.
The primary aim of this study is to determine whether black ink tattoo injected into the axillary lymph node can be visualized intra-operatively in the same fashion blue sentinel nodes are identified. The second objective is to determine the concordance between tattooed, biopsied axillary lymph node and sentinel node. The third objective is to compare the preoperative pathological assessment on needle biopsy with the histological findings of resected nodes.
In patients undergoing breast-conserving surgery and having positive sentinel lymph nodes (SLNs), the ACOSOG Z0011 trial showed equivalent overall survival(OS) and disease-free survival(DFS) outcomes for patients receiving SLN dissection (SLND) alone and those receiving axillary lymph node dissection (ALND). We conducted a prospective single-arm study to confirm the applicability of the Z0011 criteria to Chinese patients with breast cancer.
This clinical trial is a prospective, multicenter, self-controlled clinical study. In order to meet the requirements of this plan, 130 breast cancer patients need the sentinel lymph node biopsy with novel near-infarred fluorescence imaging system produced by Beijing digital precision medical technology co., LTD. The fluorescence molecular imaging of indocyanine green (ICG) on imaging detection and the control group, routine medical using methylene blue test .The safety and efficacy of fluorescence and staining in sentinel lymph node biopsy of breast cancer were compared.
The present study aims at investigating the feasibility, the detection rate and the negative predictive value of sentinel node in predicting the presence or absence of lymph node metastasis in ovarian cancer patients
Investigators aimed to determine the validity of the investigator's novel tumor targeted fluorescent peptide TMTP1-ICG to increased accuracy of laparoscopic SLN mapping
This study has been designed to validate a non-radioactive method to identify the sentinel lymph node using a superparamagnetic iron-oxide (SPIO) tracer respect to the traditional isotopic method. Both methods are used in every included patient and each patient is its own control.
The objective of this study is to determine if fluorescence lymphangiography can be used alone to localize sentinel nodes in patients with melanoma or breast cancer. The hypothesis is that sentinel nodes can be identified using only indocyanine green (ICG) and fluorescence lymphangiography, without the need for technetium99 and a gamma probe.
Purpose: To prove the feasibility of sentinel node navigation surgery (SNNS) in early gastric cancer patients with the risk of lymph node metastasis after endoscopic resection and preparation of multicenter phase 3 trial of stomach preserving surgery in these patients. Contents: The number of enrollment is 247 patients. The patients underwent endoscopic resection for early gastric cancer, and the tumor was defined to be out of indication for endoscopic resection pathologically. So, additional gastrectomy is recommended for them. The investigators will enroll patients who agree this study. After general anesthesia, Tc99m-Phytate with indocyanine green will be injected with endoscopy. Then sentinel basin will be detected using gamma probe and laparoscopic basin dissection will be done. Sentinel lymph node will be identify in back table dissection, and patients will undergo conventional gastrectomy. Detection rate and false negative rate will be evaluated by pathological review.
