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...

Lymph nodes help to fight off infections by producing immune cells and filtering foreign materials from the body, such as bacteria or cancer cells. Thus, one of the first places that cancer cells are found when they leave the primary tumor is in the lymph nodes. The spread of cancer cells to the lymph nodes, lymphatic metastasis, is known to indicate a poor prognosis in many types of cancers; how tumor cells reach the lymph nodes, however, is not well understood. A new study by Dr. Heide...

Metastasis of tumors to level IIb lymph nodes is rare in patients with laryngeal squamous cell carcinoma (LSCC); this area can be ignored during selective neck dissection (SND) to avoid damaging the spinal accessory nerve (SAN), making this surgery more conservative and minimizing SAN morbidity, according to the March 2012 issue of Otolaryngology—Head and Neck Surgery. The authors acknowledge that the medical literature stresses the importance of preserving the SAN to prevent...

(Ivanhoe Newswire) -- A new study shows removing lymph nodes because of the presence of microscopic cancer cells found in the sentinel node has no impact on survival among women with early-stage breast cancer. Researchers studied more than 5,000 women with breast cancer at 126 sites around the country. All the participants underwent breast-conserving surgery and sentinel lymph node dissection. The sentinel lymph node is the one that is closest to the tumor. Results showed survival outcomes...

Study reported in Journal of the American Medical Association A 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...

In the largest reported series yet to compare transcervical extended mediastinal lymphadenectomy (TEMLA) with endoscopic and surgical primary staging and restaging of non-small cell lung cancer (NSCLC), TEMLA showed a significantly higher diagnostic yield, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC). Diagnostic yield refers to the likelihood that a procedure will provide...

Surgeon Naia Uribe-Etxebarria has used a radioactive substance which, injected into a lung tumour, enables the detection of the path that the carcinoma intends to take in order to propagate itself. Concretely she applied technetium 99 in resectable non-small cell lung cancers (NSCLC) at an early stage (I or II), and in an intraoperative manner. Thanks to this, she detected with precision the sentinel node (SNOL); the primary node or ganglion of cells to receive lymphatic drainage from the...

Current status and future directions explored in issue of Breast Disease The sentinel node (SN) procedure in breast cancer is based on the premise that if the first node into which breast tissue drains is clean, the remaining lymph nodes in the armpit are likely not involved, with no need for removal. This was developed to limit surgical overtreatment and reduce morbidities such as blockage of lymph vessels and shoulder dysfunction. However, in the initial years of the SN procedure, surgeries...

Photodynamic ablation of lymphatic vessels and intralymphatic cancer cells prevents metastasis Tumor cells have several routes that enable them to move from the primary tumor to distant tissues, a process called metastasis. It is metastasis of the primary tumor that kills most cancer patients. One of the least studied routes of metastasis is the lymphatic system. Many tumors produce factors that promote the formation of new lymphatic vessels (lymphangiogenesis). The newly formed lymphatic...
