High Complication Rate after Introduction of Transbronchial Cryobiopsy into Clinical Practice at an Academic Medical Center

DiBardino, David M; Haas, Andrew R; Lanfranco, Anthony R; Litzky, Leslie A; Sterman, Daniel; Bessich, Jamie L
RATIONALE: Transbronchial cryobiopsy is an emerging technique for obtaining biopsies of lung parenchyma. Despite limited evidence of safety and efficacy in direct comparison to other available biopsy procedures, pulmonologists are integrating this technique into clinical practice with the hope of avoiding the risks of surgical lung biopsy. OBJECTIVES: To report the rate of severe complications and diagnostic outcomes immediately after introduction of transbronchial cryobiopsy into the clinical practice of a single-center, high-volume, interventional pulmonary group at a large academic medical center in the United States. METHODS: Retrospective review of a case series. RESULTS: Twenty-five consecutive patients underwent transbronchial cryobiopsy for a variety of indications over a period of 14 weeks. In the absence of a strict protocol, a variety of techniques was employed by four attending interventional pulmonologists and one advanced interventional pulmonology fellow to plan and complete the procedures. Three patients (12%) experienced serious hemorrhage immediately after biopsy, including one patient who survived a life-threatening bleed. Two procedures were complicated by an iatrogenic pneumothorax. One patient experienced hypercapnic respiratory failure shortly after the procedure. A definitive diagnosis was made on 14 cryobiopsies (56%). Another 5 biopsies (20%) contributed to a presumptive diagnosis achieved by multidisciplinary consensus. CONCLUSIONS: Transbronchial cryobiopsy may have diagnostic and safety limitations that are not yet well appreciated given the state of the published medical literature. Major questions remain regarding the safest procedural protocol to be used when performing transbronchial cryobiopsy. Thorough planning and a high degree of caution are encouraged on first introduction of this technique into a clinical practice.

Recent Advances in Bronchoscopic Treatment of Peripheral Lung Cancers

Harris, Kassem; Puchalski, Jonathan; Sterman, Daniel
The detection of peripheral lung nodules is increasing due to expanded use of computed tomography (CT) and implementation of lung cancer screening recommendations. Although surgical resection of malignant nodules remains the treatment modality of choice at present, many patients are not surgical candidates, thus prompting the need for other therapeutic options. Stereotactic body radiotherapy (SBRT) and percutaneous thermal ablation are emerging as viable alternatives to surgical resection. For safety, efficacy, and cost-effectiveness purposes, however, alternative bronchoscopic methods for treatment of peripheral lung cancer are currently under active exploration. We searched the Cochrane Library and Medline from 1990 to 2015 to provide the most comprehensive review for bronchoscopic treatment of malignant lung nodules. We used the following search terms: bronchoscopy; lung nodule; peripheral lung lesion; and bronchoscopic treatment. We focused on peripheral pulmonary nodules that are confirmed or highly likely to be malignant. Seventy-one articles were included in this narrative review. We provide herein an overview of advanced bronchoscopic modalities that have been utilized or are under active investigation for definitive treatment of malignant pulmonary nodules. We concisely discuss the use of direct intratumoral chemotherapy or gene therapies, transbronchial brachytherapy, bronchoscopy-guided radiofrequency ablation, placement of markers to guide real time radiation and surgery, cryotherapy and photodynamic therapy. We also briefly report on emerging technologies such as vapor ablation of lung parenchyma for lung cancers. Advances in bronchoscopic therapy will bring additional treatment options to patients with peripheral lung malignancies, with putative advantages over other minimally invasive modalities.

Extended Pleurectomy-Decortication-Based Treatment for Advanced Stage Epithelial Mesothelioma Yielding a Median Survival of Nearly Three Years

Friedberg, Joseph S; Simone, Charles B; Culligan, Melissa J; Barsky, Andrew R; Doucette, Abigail; McNulty, Sally; Hahn, Stephen M; Alley, Evan; Sterman, Daniel H; Glatstein, Eli; Cengel, Keith A
BACKGROUND:The purpose of this study was to assess survival for patients with malignant pleural mesothelioma (MPM), epithelial subtype, utilizing extended pleurectomy-decortication combined with intraoperative photodynamic therapy (PDT) and adjuvant pemetrexed-based chemotherapy. METHODS:From 2005 to 2013, 90 patients underwent lung-sparing surgery and PDT for MPM. All patients had a preoperative diagnosis of epithelial subtype, of which 17 proved to be of mixed histology. The remaining 73 patients with pure epithelial subtype were analyzed. All patients received lung-sparing surgery and PDT; 92% also received chemotherapy. The median follow-up was 5.3 years for living patients. RESULTS:Macroscopic complete resection was achieved in all 73 patients. Thirty-day mortality was 3% and 90-day mortality was 4%. For all 73 patients (89% American Joint Commission on Cancer stage III/IV, 69% N2 disease, median tumor volume 550 mL), the median overall and disease-free survivals were 3 years and 1.2 years, respectively. For the 19 patients without lymph node metastases (74% stage III/IV, median tumor volume 325 mL), the median overall and disease-free survivals were 7.3 years and 2.3 years, respectively. CONCLUSIONS:This is a mature dataset for MPM that demonstrates the ability to safely execute a complex treatment plan that included a surgical technique that consistently permitted achieving a macroscopic complete resection while preserving the lung. The role for lung-sparing surgery is unclear but this series demonstrates that it is an option, even for advanced cases. The overall survival of 7.3 years for the node negative subset of patients, still of advanced stage, is encouraging. Of particular interest is the overall survival being approximately triple the disease-free survival, perhaps PDT related. The impact of PDT is unclear, but it is hoped that it will be established by an ongoing randomized trial.

PILOT AND FEASIBILITY TRIAL OF IMMUNO-GENE THERAPY OF MALIGNANT MESOTHELIOMA USING INTRAPLEURAL DELIVERY OF ADENOVIRUS- INTERFERON-ALPHA COMBINED WITH CHEMOTHERAPY

Sterman, Daniel H; Alley, Evan; Stevenson, James P; Friedberg, Joseph; Metzger, Susan; Recio, Adri; Moon, Edmund K; Haas, Andrew R; Vachani, Anil; Katz, Sharyn I; Sun, Jing; Heitjan, Daniel; Hwang, Wei-Ting; Litzky, Leslie; Yearley, Jennifer H; Tan, Kay See; Papasavvas, Emmanouil; Kennedy, Paul; Montaner, Luis; Cengel, Keith A; Simone, Charles B; Culligan, Melissa; Langer, Corey; Albelda, Steven M
PURPOSE: "In situ vaccination" using immuno-gene therapy has the ability to induce polyclonal anti-tumor responses directed by the patient's immune system. EXPERIMENTAL DESIGN: Patients with unresectable MPM received two intrapleural doses of a replication-defective adenoviral vector containing the human interferon-alpha2b gene (Ad.IFN) concomitant with a 14-day course of celecoxib followed by chemotherapy. Primary outcomes were safety, toxicity, and objective response rate; secondary outcomes included progression-free and overall survival. Bio-correlates on blood and tumor were measured. RESULTS: Forty subjects were treated: 18 received first-line pemetrexed-based chemotherapy, 22 received second-line chemotherapy with pemetrexed (n=7) or gemcitabine (n=15). Treatment was generally well tolerated. The overall response rate was 25% and the disease control rate was 88%. Median overall survival (MOS) for all patients with epithelial histology was 21 months versus 7 months for patients with non-epithelial histology. MOS in the first-line cohort was 12.5 months, while MOS for the second-line cohort was 21.5 months, with 32% of patients alive at 2 years. No biologic parameters were found to correlate with response, including numbers of activated blood T cells or NK cells, regulatory T cells in blood, peak levels of interferon-alpha in blood or pleural fluid, induction of anti-tumor antibodies, nor an immune-gene signature in pretreatment biopsies. CONCLUSIONS: The combination of intrapleural Ad.IFN, celecoxib, and chemotherapy proved safe in patients with MPM. Overall survival rate was significantly higher than historical controls in the second-line group. Results of this study support proceeding with a multi-center randomized clinical trial of chemo-immunogene therapy versus standard chemotherapy alone.

Enrichment of the lung microbiome with oral taxa is associated with lung inflammation of a Th17 phenotype

Segal, Leopoldo N; Clemente, Jose C; Tsay, Jun-Chieh J; Koralov, Sergei B; Keller, Brian C; Wu, Benjamin G; Li, Yonghua; Shen, Nan; Ghedin, Elodie; Morris, Alison; Diaz, Phillip; Huang, Laurence; Wikoff, William R; Ubeda, Carles; Artacho, Alejandro; Rom, William N; Sterman, Daniel H; Collman, Ronald G; Blaser, Martin J; Weiden, Michael D
Microaspiration is a common phenomenon in healthy subjects, but its frequency is increased in chronic inflammatory airway diseases, and its role in inflammatory and immune phenotypes is unclear. We have previously demonstrated that acellular bronchoalveolar lavage samples from half of the healthy people examined are enriched with oral taxa (here called pneumotypeSPT) and this finding is associated with increased numbers of lymphocytes and neutrophils in bronchoalveolar lavage. Here, we have characterized the inflammatory phenotype using a multi-omic approach. By evaluating both upper airway and acellular bronchoalveolar lavage samples from 49 subjects from three cohorts without known pulmonary disease, we observed that pneumotypeSPT was associated with a distinct metabolic profile, enhanced expression of inflammatory cytokines, a pro-inflammatory phenotype characterized by elevated Th-17 lymphocytes and, conversely, a blunted alveolar macrophage TLR4 response. The cellular immune responses observed in the lower airways of humans with pneumotypeSPT indicate a role for the aspiration-derived microbiota in regulating the basal inflammatory status at the pulmonary mucosal surface.
