Fetal adenocarcinoma is a rare lung malignancy associated with improved outcomes compared to more common adenocarcinoma variants. We describe a case of a 31-year-old woman who presented with right-sided chest pain, and was subsequently diagnosed with an intermediate-grade stage IV fetal adenocarcinoma with chest wall invasion. She was treated with surgical resection and adjuvant radiation., (Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

Adjuvant radiotherapy after complete resection of localized, invasive thymic epithelial tumors is considered by many to be the standard of care, despite little supporting literature. We hypothesized that individual studies may lack statistical power to demonstrate a reduction in recurrence with this approach, but meta-analysis of published data may allow for more adequate statistical evaluation. Analysis of data from 592 patients with completely resected stage II or III thymic epithelial tumors, however, revealed no statistically significant reduction in recurrence after adjuvant radiotherapy (odds ratio 1.05; 95% confidence interval: 0.63 to 1.75; p = 0.840). Additionally, the majority of publications suggest that the most common sites of recurrence are the lung, pleura, and diaphragm, even when incompletely resected patients are included.

Background: The current international staging system for lung cancer designates intralobar satellites as T4 disease. In this study, we sought to determine the impact of multifocal, intralobar non-small cell lung cancer (NSCLC) on patient survival and its potential relevance to stage designation., Methods: We conducted a retrospective review of our thoracic surgical cancer registry from 1990 to 2005. Included were 53 patients with a resected lung cancer containing intralobar satellites detected preoperatively (n = 8) or in the resected specimen (n = 45). Patients with multicentric bronchioloalveolar cancer were excluded. All patients had an anatomic resection with mediastinal lymph node dissection. Median follow-up for the entire group was 31 months. Survival was calculated by the Kaplan-Meier method. A Cox proportional hazards regression model was performed to examine simultaneously the effects on overall survival of age, gender, nodal disease, number of satellite lesions, lymphatic invasion, and T status., Results: The median age of the 53 patients with multifocal, intralobar (T4) disease was 68 years and 31 were women. Ten patients had more than one satellite lesion. Overall 5-year survival was 47.6% (95% confidence interval [CI], 27.36% to 65.30%) for all patients with resected intralobar satellites. Patients without nodal metastases had a 5-year survival of 58.4% (95% CI, 28.76% to 79.30%). The Cox regression identified female gender (adjusted hazard ratio [HR], 0.31; 95% CI, 0.10 to 0.96; p < 0.04) as a significant prognostic variable but only a trend towards significance for nodal status (adjusted HR, 2.3; 95% CI, .83 to 6.26; p < 0.11)., Conclusions: Patients with intralobar multifocal NSCLC detected in the resected specimen have a more favorable prognosis after surgical resection than might be predicted by their stage T4 designation. Five-year survival rates, especially in T4N0 patients, more closely approximate those with stages IB or II NSCLC.

Background: To determine the eventual outcome of abnormalities detected on surveillance computed tomography (CT) in patients with previously resected nonsmall-cell lung cancer (NSCLC), and to assess the accuracy of CT when used by the thoracic surgeon, and to determine the characteristics of abnormalities on CT that correlate with the development of recurrent NSCLC., Methods: A cohort of patients who had abnormal postoperative CT scans of the chest and upper abdomen in 2002 were followed up into 2005. Abnormalities consisted of pulmonary nodules, pleural effusions, or adenopathy. Data collected included recurrence patterns, the availability of previous scans for comparison, the interval between initial resection and the abnormal CT, nodule size, growth, and multiplicity, as well as progression of pleural effusions or adenopathy., Results: In all, 105 scans in 92 patients were read as abnormal in 2002 by the radiologist. After further investigation or follow-up, or both, for a mean of 3.2 years, 78% of patients who had recurrent NSCLC had their site of first recurrence inside the chest. The negative predictive value of CT when used by the thoracic surgeon was 99%; however, the positive predictive value was only 53%. Abnormalities that correlated with the diagnosis of recurrent cancer included pulmonary nodules that either grew or were larger than 1 cm and pleural effusions that developed after the first postoperative year., Conclusions: Intrathoracic recurrent NSCLC was rarely missed by the surgeon utilizing surveillance CT, but a significant number of negative investigations were generated by its use. Characteristics of abnormal surveillance CT findings exist that correlate with the presence of malignancy.

Background: The purposes of this study were to determine the frequency of downstaging of T or N after neoadjuvant chemotherapy and radical resection in patients with carcinoma of the esophagus, and to evaluate the effect of tumor downstaging on survival., Methods: A cohort of patients who underwent neoadjuvant chemotherapy followed by radical surgical resection for carcinoma of the esophagus was identified from a large, prospectively maintained, single-institution database of esophageal cancer patients. Patients were included if they had an accurate pretreatment clinical stage determined by the authors. Data collected included demographic data, the type of staging regimen, the chemotherapy agents used, clinical and pathologic data and stages, and survival data. Downstaging of T or N was determined by comparing the pretreatment, clinical stage to the postresection, pathologic stage. Downstaging was then evaluated in the context of survival., Results: Seventy-seven patients were identified who had an accurate clinical stage assigned and underwent neoadjuvant chemotherapy followed by radical resection. Patients were clinically staged before treatment using computed tomography, positron emission tomography, and endoscopic ultrasonography. Thirty-seven patients (48%) experienced downstaging of T or N, and this group of patients had a 5-year overall actuarial survival of 63%, compared with 23% for those who were not downstaged (p = 0.002). Three patients had a complete pathologic response to neoadjuvant chemotherapy (3.9%)., Conclusions: Patients who experience downstaging of T or N after neoadjuvant chemotherapy and radical surgical resection for esophageal carcinoma have a significantly higher survival rate compared with those who do not experience downstaging. This enhanced survival is comparable to survival rates reported in complete pathologic responders after neoadjuvant chemoradiation.
