Background: The Leo W. Jenkins Cancer Clinic has adopted a programmatic, multidisciplinary approach to thoracic tumors, which has involved the implementation of new therapeutic and diagnostic approaches. In 2012 we began using electromagnetic navigational bronchoscopy (ENB) as a new diagnostic tool. ENB uses a guidance system that combines CT imaging with magnetic field–guided spatial information to allow tissue sampling or placement of fiducial markers to guide radiation therapy. Methods: The numbers of early-stage (I and II) and late-stage (III and IV) lung cancers were compared before and after the introduction of ENB. We also examined the number of cases of fiducial marker placement using bronchoscopy versus interventional radiology before and after ENB was introduced. Fisher's exact test was used to compare the early- versus late-stage lung cancers found at diagnosis pre- and post-ENB introduction, fiducial marker placements using interventional radiology versus bronchoscopy pre- and post-ENB introduction, and pneumothorax rates. Results: More early-stage cancers were diagnosed after ENB introduction (67 of 286 cases vs 116 of 290; P<.0001). Bronchoscopy was also used more frequently to place fiducial markers post-ENB (53 of 86 pre-ENB vs 105 of 117 post-ENB; P<.0001) and had a lower pneumothorax rate (4% vs 22%) than fiducial placement in interventional radiology (P<.001). Conclusions: The addition of ENB to a multidisciplinary thoracic oncology program may permit the diagnosis of lung cancer at an earlier stage and offers the ability to safely place fiducial markers for therapeutic purposes, such as radiation therapy, within the same procedure, potentially improving safety and decreasing time to treatment.

Abstract

The National Comprehensive Cancer Network (NCCN) first published the NCCN Breast Cancer Treatment Guidelines in 1996. The Guidelines address the treatment of all stages of breast cancer across the spectrum of patient care and have been updated yearly. Adjuvant therapy for breast cancer has undergone an especially rapid evolution over the past few years. Therefore, the NCCN Breast Cancer Guidelines Panel was supplemented by additional experts to form the Adjuvant Therapy Task Force to provide a forum for an extended discussion and expanded input to the adjuvant therapy recommendations for the Breast Cancer Treatment Guidelines. Issues discussed included methods of risk-stratification for recurrence; how biologic markers such as HER2 status, quantitative estrogen receptor, or genetic markers can be incorporated as prognostic or predictive factors; and how age, menopausal status, and estrogen receptor levels impact benefits from chemotherapy and endocrine therapy. Additionally, the task force discussed the strategies for use of aromatase inhibitors in postmenopausal women and the potential incorporation of trastuzumab into adjuvant therapy of women with HER2/neu positive breast cancer. This supplement summarizes the background data and ensuing discussion from the Adjvuant Task Force meeting. (JNCCN 2006;4[suppl 1]:S-1–S-26)

The NCCN Guidelines for Central Nervous System Cancers provide multidisciplinary recommendations for the clinical management of patients with cancers of the central nervous system. These NCCN Guidelines Insights highlight recent updates regarding the management of metastatic brain tumors using radiation therapy. Use of stereotactic radiosurgery (SRS) is no longer limited to patients with 3 or fewer lesions, because data suggest that total disease burden, rather than number of lesions, is predictive of survival benefits associated with the technique. SRS is increasingly becoming an integral part of management of patients with controlled, low-volume brain metastases.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Central Nervous System (CNS) Cancers provide interdisciplinary recommendations for managing adult CNS cancers. Primary and metastatic brain tumors are a heterogeneous group of neoplasms with varied outcomes and management strategies. These NCCN Guidelines Insights summarize the NCCN CNS Cancers Panel's discussion and highlight notable changes in the 2015 update. This article outlines the data and provides insight into panel decisions regarding adjuvant radiation and chemotherapy treatment options for high-risk newly diagnosed low-grade gliomas and glioblastomas. Additionally, it describes the panel's assessment of new data and the ongoing debate regarding the use of alternating electric field therapy for high-grade gliomas.
