thoracic tumor board

In-Jae Oh, Sung-Ja Ahn
Locally advanced non-small cell lung cancer (LA-NSCLC) is composed of heterogeneous subgroups that require a multidisciplinary team approach in order to ensure optimal therapy for each patient. Since 2010, the National Comprehensive Cancer Network has recommended chemoradiation therapy (CRT) for bulky mediastinal disease and surgical combination for those patients with single-station N2 involvement who respond to neoadjuvant therapy. According to lung cancer tumor boards, thoracic surgeons make a decision on the resectability of the tumor, if it is determined to be unresectable, concurrent CRT (CCRT) is considered the next choice...

PURPOSE: To develop an adaptive prior knowledge guided image estimation technique to reduce the scan angle needed in the Limited-Angle Intrafraction Verification (LIVE) system for 4D-CBCT reconstruction. METHOD: The LIVE system has been previously developed to reconstruct 4D volumetric images on-the-fly during arc treatment for intrafraction target verification and dose calculation. In this study, we developed an adaptive constrained free-form deformation reconstruction technique in LIVE to further reduce the scanning angle needed to reconstruct the 4D-CBCT images for faster intrafraction verification...

PURPOSE: The target volume for Whole Breast Irradiation (WBI) is dictated by location of tumor mass, breast tissue distribution, and involvement of lymph nodes. Dose coverage and Organs at Risk (OARs) sparing can be difficult to achieve in patients with unfavorable thoracic geometries. For these cases, inverse-planned and 3D-conformal prone treatments can be alternatives to traditional supine 3D-conformal plans. A dosimetric comparison can determine which of these techniques achieve optimal target coverage while sparing OARs...

Breast cancer (BC) in men represents between 0.5% and 1% of all BC diagnosed each year. We report a case of advanced BC in a 62-year-old male treated at our interdisciplinary Breast Cancer Center. The patient presented with a newly diagnosed large, symptomatic mass in his left breast. Clinical examination showed a not movable mass of 16 cm diameter, deforming the whole breast; the overlying skin was livid and hypervascularized. Enlarged lymph nodes were palpable in the axillary pit. He had no concomitant diseases at time of presentation...

BACKGROUND: Multiple primary lung cancer is a relatively rare nosological entity. This case report is a reminder and points out the pitfalls of its diagnosis and therapy. CASE REPORT: A 62-year-old patient was indicated for surgical therapy for non-small cell lung cancer of the middle lobe and right lung, which were diagnosed during a screening investigation after the patient had undergone previous mastectomy of the right breast with axillary dissection for invasive ductal adenocarcinoma...

INTRODUCTION: Positron emission tomography (PET) imaging with fluorine-18-fluorodeoxyglucose (18F-FDG) is widely known for its use in the diagnosis and tracking of primary and metastatic tumors via uptake and retention of the radiopharmaceutical by hypermetabolic cells. 18F-FDG is also used to study the normal physiology of glucose uptake, metabolism, and muscle activity during and after exercise. BACKGROUND: A pilot study adding PET imaging to the diagnostic evaluation of canine patients undergoing computed tomography (CT) for mild or intermittent thoracic and pelvic limb lameness is ongoing...

PURPOSE: To prospectively evaluate the capability of amide proton transfer-weighted chemical exchange saturation transfer magnetic resonance (MR) imaging for characterization of thoracic lesions. MATERIALS AND METHODS: The institutional review board approved this study, and written informed consent was obtained from 21 patients (13 men and eight women; mean age, 72 years) prior to enrollment. Each patient underwent chemical exchange saturation transfer MR imaging by using respiratory-synchronized half-Fourier fast spin-echo imaging after a series of magnetization transfer pulses...

BACKROUND: Colorectal carcinoma has the third highest incidence of all tumor diseases in the world. In the long term, Slovak republic is among countries with highest occurrence of this disease. About 25% of patients have distant metastases at the time of diagnosis, and about 50% of patients progress. The first possibility of colorectal carcinoma lung metastases treatment is metastasectomy which may have a curative character. MATERIALS AND METHODS: In this paper, the authors retrospectively evaluated 50 patients who had undergone surgical treatment to establish the diagnosis of colorectal carcinoma lung metastases at the Clinic of thoracic surgery of JLF UK and UH Martin between 2003 and 2014...

UNLABELLED: The purpose of this study was to compare the diagnostic accuracy of whole-body unenhanced PET/MR with that of PET/CT in determining the stage of non-small cell lung cancer. METHODS: This study was approved by the institutional review board and by national government authorities. Forty-two consecutive patients referred for the initial staging of non-small cell lung cancer underwent whole-body imaging with a sequential trimodality PET/CT/MR system. PET/MR and PET/CT datasets were evaluated separately, and a TNM stage was assigned on the basis of the image analysis...

BACKGROUND: The Summa Cancer Institute in Akron, Ohio, sought to improve access to and the timeliness of lung cancer care by hiring an oncology-certified nurse navigator. The nurse navigator was charged with coordinating diagnostic procedures and specialty oncology consultations, and with facilitating a multidisciplinary thoracic oncology tumor board. OBJECTIVE: To test the hypothesis that nurse navigation would improve the timeliness of and access to diagnostic medical services among men and women with newly diagnosed lung cancer...

The present study aimed to evaluate the role of adjuvant radiotherapy (RT) following nipple-sparing mastectomy (NSM) for patients with ductal carcinoma in situ and invasive breast cancer, based on the published literature. Currently, there is no standard for RT following NSM. NSM aims to spare the nipple areola complex (NAC) without compromising locoregional control. Long-term follow-up studies have begun to show promising results. A search of the English literature was performed using the Medline database and Cochrane central library, with the keywords 'nipple/areola-sparing mastectomy', 'whole skin mastectomy' and 'NAC preservation'...

PURPOSE: 4D-CBCT facilitates assessment of tumor motion at treatment position. We investigated the effect of gantry speed on 4D-CBCT image quality and dose using the Varian Edge On-Board Imager (OBI). METHODS: A thoracic protocol was designed using a 125 kVp spectrum. Image quality parameters were obtained via 4D acquisition using a Catphan phantom with a gating system. A sinusoidal waveform was executed with a five second period and superior-inferior motion. 4D-CBCT scans were sorted into 4 and 10 phases...

BACKGROUND: This study evaluated the 2-year overall survival rate, adverse event rate, local control rate, and impact on pulmonary function tests for medically inoperable patients with stage IA non-small cell lung cancer (NSCLC) undergoing computed tomography (CT)-guided radiofrequency ablation (RFA) in a prospective, multicenter trial. METHODS: Fifty-four patients (25 men and 29 women) with a median age of 76 years (range, 60-89 years) were enrolled from 16 US centers; 51 patients were eligible for evaluation (they had biopsy-proven stage IA NSCLC and were deemed medically inoperable by a board-certified thoracic surgeon)...

OBJECTIVE OF THE STUDY: To identify risk factors for the adverse events and determine the diagnostic yield of a large series of image-guided thoracic biopsies performed in a single institution. MATERIALS AND METHODS: We reviewed a consecutive series of 811 patients (546 males; average age: 68 years.) who underwent 824 image-guided biopsies of pulmonary lesions performed between 2009 and 2013. Indications for biopsy were always evaluated by a multidisciplinary board...

BACKGROUND: National and subspecialty guidelines for lung and esophageal cancers recommend treatment decisions to be made in a multidisciplinary tumor board (MTB). This study prospectively analyzes the actual impact of presentation at the thoracic tumor board on decision making in thoracic cancer cases. METHODS: During the electronic submission process for presentation at MTB managing physicians documented their current treatment plan. The initial treatment plan was compared with the MTB final recommendation...
