Benefit of Lymph Node Biopsies May Be Limited in Microinvasive Breast Cancer
Researchers sought to determine the benefit of managing microinvasive breast cancer similarly to invasive tumors in a retrospective study.
Lymph Nodes
New Evidence Shows Metastases May Spread Independently of Lymph Nodes
A recent study found that nodal tumors and distant metastases originate from different areas of the primary tumor, suggesting that cancer spreads independently of the lymph nodes.
Staging by Lymph Node Categories Shown to Better Predict Survival in Patients With Oropharyngeal Cancer
The current staging system for oropharyngeal cancer does not adequately differentiate HPV-positive from HPV-negative OPC. These researchers suggest regional OPC lymph node (N) categories and nasopharyngeal N categories might be more useful in staging HPV-positive OPC.
Interferon Has Little Benefit for Patients With Small Amounts of Melanoma in the Lymph Nodes
No evidence that interferon is necessary or helpful in cases of melanoma with minimal metastasis to the lymph nodes, according to the final results of the Sunbelt Melanoma Trial.
Radiotherapy to the Axilla Can Replace Axillary Lymph Node Dissection in Select Patients
Recent trial data indicate that axillary lymph node dissection (ALND) can be safely omitted in select patients, according to a research presented at the 2015 San Antonio Breast Cancer Symposium.
Internal Mammary Lymph Nodes Discovered With MRI Likely to Be Benign
Internal mammary lymph nodes (IMLNs) identified at implant-protocol breast magnetic resonance imaging (MRI) are more likely to be benign than malignant.
Adding regional nodal irradiation to whole-breast irradiation reduces breast cancer recurrence
Radiation to the lymph nodes as well as the standard treatment of whole-breast irradiation after breast-conserving surgery does not confer an overall survival benefit.
Regional node irradiation in breast cancer improves overall survival
The effect of irradiation of regional nodes in patients with stage I, II, or III breast cancer on overall survival is very limited, according to a study.
Extended-Field IMRT Does Not Increase Risk of Duodenal Toxicity
Women with cervical or endometrial cancer can safely receive extended-field intensity modulated radiation therapy (EF-IMRT) without increased risk of duodenal toxicity.
Growth of lymph node metastases does depend on new blood vessel development
The growth of metastases in lymph nodes does not require new blood vessels, but rather utilizes existing blood vessels.
