Latest Lymph node biopsy Stories

Contrary to a trend in treatment, breast cancer patients with suspicious lymph nodes should have an ultrasound-guided axillary node biopsy, and if that biopsy is positive these patients should undergo an axillary dissection, a new study shows. The study, conducted at the University of Pittsburgh Medical Center, compared 199 patients with a positive ultrasound-guided axillary node biopsy to 434 patients with a positive sentinel lymph node biopsy. "About 50% of patients with a positive...

Pathology evaluations done on-site cut operating time, reduced cost, study shows ANN ARBOR, Mich., March 1, 2012 /PRNewswire-USNewswire/ -- Nearly one in three women who have breast cancer surgery will need to return to the operating room for additional surgery after the tumor is evaluated by a pathologist. A new service at the University of Michigan Comprehensive Cancer Center cuts that number drastically by having pathologists on-site in the operating suite to assess tumors...

Patients with Merkel Cell Carcinoma who underwent a procedure called sentinel lymph node biopsy (SNLB) had a lower risk of cancer recurrence after two years, according to a study by researchers from Fox Chase Cancer Center. When the biopsy's results were used to guide subsequent tests and treatment, these patients had longer survival rates than patients who had not undergone the procedure. "Sentinel lymph node biopsy, or SNLB, can be used to recommend which way to proceed with a patient's...

Study refutes controversy about technique in delicate head, neck regionA common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area, according to a new study from the University of Michigan Comprehensive Cancer Center.Sentinel lymph node biopsy involves injecting a special dye to identify the first node where cancer would likely spread. If that node is clean, patients can avoid further debilitating surgery to...

Study reported in Journal of the American Medical AssociationA new study shows that removing lymph nodes due to the presence of occult, or microscopic, cancer cells found in the sentinel lymph node "“ the one closest to the tumor -- has no impact on survival outcomes of women with early-stage breast cancer. The principal investigator of the study is Armando E. Giuliano, MD, of Cedars-Sinai, who already is renowned for his clinical expertise and for his seminal research on lymph node removal...

Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a second breast cancer surgery, a new study in shows.Patients with early breast cancer undergo a sentinel lymph node biopsy to determine if their cancer has spread, said Dr. Ali Sever, lead author of the study. Ultrasound, on its own, can't distinguish the sentinel lymph node from other...

Photoacoustics technology could make some lab processes more efficient, says MU researcherKnowing the stage of a patient's melanoma is important when choosing the best course of treatment. When the cancer has progressed to the lymph nodes, a more aggressive treatment is needed. Examining an entire lymph node for cancer takes much effort and time; a new technique might help make the process more efficient. University of Missouri researchers in the Christopher S. Bond Life Sciences Center are...

University of Michigan Health System researchers have published new data to help answer two dreaded questions: "Is it cancer?" and "What type of treatment should I have?"Cancer is the primary concern when abnormal skin lesions are detected. Macroscopic and microscopic features of a lesion usually provide clues about whether it is benign or malignant. However, the distinction is not always clear-cut, and doctors are faced with the question of how to best treat such...

Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. For the first time, Lihong Wang, Ph.D., Gene K. Beare Distinguished Professor in the Department of Biomedical Engineering, with a joint appointment in Radiology, and Younan Xia, Ph.D., James M. McKelvey Professor in Biomedical Engineering, with a joint appointment in chemistry in Arts & Sciences, both at Washington University in St. Louis, have used gold...

By Lachar, Whitney A Shahab, Imran; Saad, A Joe * Context.-Lymphomas have traditionally been diagnosed on excisional biopsies of lymph nodes in order to evaluate tissue architecture and cytomorphology. Recent lymphoma classification schemes emphasize immunophenotypic, genetic, and molecular aspects in addition to morphology as diagnostic features. Core needle biopsies are increasingly being used to obtain tissue for diagnosis in patients with lymphadenopathy and a clinical suspicion of...
