RATIONALE: Diagnostic procedures, such as lymph node mapping and sentinel lymph node identification, performed before and during surgery, may improve the ability to detect lymph node metastases in patients who have cervical cancer.
PURPOSE: This clinical trial is studying how well lymph node mapping and sentinel lymph node identification work in finding lymph node metastases in patients with stage IB1 cervical cancer.
- Determine the sensitivity of the sentinel lymph node in the determination of lymph node metastases, using preoperative or intraoperative lymphatic mapping, in patients with stage IB1 cervical cancer.
- Determine the false-negative predictive value of the sentinel lymph node in the determination of lymph node metastases in these patients.
OUTLINE: This is a multicenter study.
Patients receive radiolabeled technetium Tc 99m sulfur colloid injected around the tumor 6 hours prior to or after induction of anesthesia right before surgery. Patients then undergo radical hysterectomy and complete pelvic and low para-aortic lymphadenectomy. Intraoperatively, patients undergo lymphatic mapping and sentinel lymph node identification using isosulfan blue or methylene blue injected at 4 locations in the cervix and a hand-held gamma counter.
PROJECTED ACCRUAL: A total of 295-590 patients will be accrued for this study within 18-36 months.

The goal of this clinical research study is to compare methylene blue (an oral rinse) to standard therapy to learn if one is better, the same, or worse than the other in controlling mucosi...
We hypothesized that pre-treatment with methylene blue could potentiate the effects of general anaesthetic agents in patients undergoing parathyroidectomy
The purpose of this study is to map the arm lymphatic drainage system in the axilla with blue dye and the breast drainage system with a radioactive material. By identifying the arm lymphat...
RATIONALE: Diagnostic procedures, such as visceral lymphatic mapping using isosulfan blue, may help find cancer of the pancreas, colon, stomach, small intestine, or gallbladder and find ou...
Open label prospective, non-randomised proof of principle study assessing the use of methylene blue fluorescence cholangiography.
An oral formulation of methylene blue with colonic delivery (MB-MMX) has been developed to increase detection of colorectal polys during colonoscopy. Traditionally, there have been safety concerns ...
Curcumin and salicylic acid are both phenolic compounds and they can both affect cancer treatment efficacy. In this study, the effects of methylene blue-curcumin (CU-MB) and methylene blue-salicylic a...
We compared the safety and feasibility of single-incision laparoscopic surgery (SILS) and conventional laparoscopic-assisted anorectoplasty (CLAARP).
A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
The metal-free blue phycobilin pigment in a conjugated chromoprotein of blue-green algae. It functions as light-absorbing substance together with chlorophylls.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
