Abstract
An 80-year-old woman who had been diagnosed with an endobronchial carcinoid tumor visited our hospital for treatment with an endoscopic technique. However, a bronchoscopic examination at our hospital showed spontaneous regression of the tumor at the orifice of the right middle lobar bronchus. Chest computed tomography five months later revealed no local recurrence. This is the second report of an endobronchial carcinoid tumor vanishing after an endoscopic biopsy.

Diagnosis of atypical carcinoid can be made on biopsies > 4 mm 2 and is accurate. Virchows Arch 2022; 480:587-593. [PMID: 35089404 PMCID: PMC8989857 DOI: 10.1007/s00428-022-03279-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 12/15/2021] [Accepted: 01/13/2022] [Indexed: 10/29/2022]
Abstract
In the 2021 WHO thoracic tumors, gradation of lung carcinoids in biopsies is discouraged. We hypothesized that atypical carcinoid (AC) could be reliably diagnosed in larger preoperative biopsies. Biopsy-resection paired specimens of carcinoid patients were included, and definitive diagnosis was based on the resection specimen according to the WHO 2021 classification. A total of 64 biopsy-resection pairs (26 typical carcinoid (TC) (41%) and 38 AC (59%)) were analyzed. In 35 patients (55%), tumor classification between the biopsy and resection specimen was concordant (26 TC, 9 AC). The discordance in the remaining 29 biopsies (45%, 29 TC, 0 AC) was caused by misclassification of AC as TC. In biopsies measuring < 4 mm2, 15/15 AC (100%) were misclassified compared to 14/23 AC (61%) of biopsies ≥ 4 mm2. Categorical concordance of Ki-67 in biopsy-resection pairs at threshold of 5% was 68%. Ki-67 in the biopsy was not of additional value to discriminate between TC and AC, irrespective of the biopsy size. Atypical carcinoid is frequently missed in small bronchial biopsies (< 4 mm2). If the carcinoid classification is clinically relevant, a cumulative biopsy size of at least 4 mm2 should be considered. Our study provides strong arguments to make the diagnosis of AC in case of sufficient mitosis for AC on a biopsy and keep the diagnosis "carcinoid NOS" for carcinoids with ≤ 1 mitosis per 2 mm2. Ki-67 has a good concordance but was not discriminative for definitive diagnosis.

Abstract
OPINION STATEMENT Primary neuroendocrine tumors (NETs) of the lung represent a heterogeneous group of malignancies arising from the endocrine cells, involving different entities, from well differentiated to highly undifferentiated neoplasms. Because of the predominance of poorly differentiated tumors, advanced disease is observed at diagnosis in more than one third of patients making chemo- or chemoradiotherapy the only possible treatment. Complete surgical resection, as defined as anatomical resection plus systematic lymphadenectomy, becomes a reliable curative option only for that little percentage of patients presenting with stage I (N0) high-grade NETs. On the other hand, complete surgical resection is considered the mainstay treatment for localized low- and intermediate-grade NETs. Therefore, in the era of the mini-invasive surgery, their indolent behavior has suggested that parenchyma-sparing resections could be as adequate as the anatomical ones in terms of oncological outcomes, leading to discuss about the correct extent of resection and about the role of lymphadenectomy when dealing with highly differentiated NETs.

Abstract
Gastrointestinal stromal tumors and neuroendocrine tumors in adult and pediatric populations differ immensely. Despite these established differences, the extreme rarity of gastrointestinal stromal tumors and neuroendocrine tumors in the pediatric population has resulted in the lack of consensus management guidelines, making optimal surgical approaches unclear. Comprehensive management principles to guide surgical approaches in adult literature are extensive. However, these are still lacking for pediatric patients. International cooperation to develop standardized pediatric-specific guidelines is urgently warranted in the future. This article highlights the vast differences between adult and pediatric parameters and provides recommendations on optimal and novel surgical approaches in children.

Abstract
BACKGROUND Atypical pulmonary carcinoid tumors represent a subset of non-small cell lung cancer; however, their relative infrequency has left prognosis, management and long-term survival associated with atypical carcinoids, incompletely characterized. METHODS Patients aged 18 years or more diagnosed with atypical or typical pulmonary carcinoid between 2010 and 2015 within the National Cancer Database were evaluated. Survival was measured using Kaplan-Meier survival and multivariable Cox proportional hazards regression, adjusting for patient and tumor attributes. RESULTS A total of 816 atypical and 5688 typical carcinoid patients were identified in the cohort. Patients with atypical carcinoids tended to be older, have larger tumors, and later stage disease. The unadjusted overall 5-year survival for atypical carcinoid patients was 84%, 74%, 52%, and 51% for stages I, II, III, and IV, respectively. The unadjusted 5-year survival for typical carcinoids was 93%, 93%, 89%, and 87% for stages I, II, III, and IV, respectively. Nodal upstaging (ie, lymph node metastases identified in surgical specimens of clinically staged N0 patients) was seen in 16% of atypical and 7% of typical carcinoid patients. Increasing age, comorbidities, and stage were identified as significant predictors of mortality for atypical patients in multivariable analysis. Extent of surgical resection (lobectomy vs sublobar) was not identified as a predictor of survival for atypical carcinoid. CONCLUSIONS Atypical carcinoid tumors represent a distinct subset of carcinoid tumors, with a tendency toward more aggressive behavior. Further study of the optimal surgical management is warranted.

Abstract
Here, we report a case of a bronchial tumor in the proximal left mainstem bronchus in a 19‐year‐old male. Diagnosis of the tumor was typical carcinoid, which was established by bronchoscopic biopsy preoperatively. Under femoral veno‐venous extracorporeal membrane oxygenation (ECMO), the patient underwent left mainstem bronchus sleeve resection through median sternotomy. The surgical resection margins were confirmed to be tumor‐free on frozen section and all lymph nodes were free of tumor. This report describes a carcinoid in the proximal mainstem bronchus which was successfully resected without lobectomy or pneumonectomy and concludes that sleeve resection under extracorporeal membrane oxygenation should be considered in the surgical treatment of mainstem bronchial carcinoid.

Abstract
Background The diagnosis of lung typical carcinoid tumors results challenging when limited size and unfavorable sampling location is associated. It has been reported that bronchoscopy with endobronchial ultrasound (EBUS) significantly increases the diagnostic yield of peripheral nodules smaller than 2 cm. Case presentation A 70-year-old Caucasian male complained of persistent fever and cough despite several antibiotic courses and steroid treatment. Chest radiology revealed the presence of a small single nodular opacity in the left upper lobe, whose standardized maximum uptake value (SUV) at fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) was significantly high (4.5). The patient underwent bronchial endoscopy but any appreciable sign of endobronchial or intramural involvement was detected. Only radial ultrasound-guided bronchoscopy (R-EBUS) allowed transbronchial sampling whose pathological analysis revealed a typical carcinoid tumor. The patients underwent surgical lobectomy and clinic-radiological follow was started. Conclusions With this case we aim at stressing the importance of ultrasound in the diagnostic process of lung small peripheral carcinoid, especially if they present without mucosal or sub mucosal involvement.

Abstract
OBJECTIVE Primary tracheobronchial tumors (PTTs) are rare heterogeneous lesions arising from any part of the tracheobronchial tree. Nonspecific symptoms may lead to delayed diagnosis that requires more aggressive surgical treatment. An analysis of cases collected by the International Network of Pediatric Airway Team was undertaken to ensure proper insight into the behavior and management of PTTs. METHODS Patients <18 years of age with a histological confirmation of PTT diagnosed from 2000 to 2015 were included in this multicenter international retrospective study. Medical records, treatment modalities, and outcomes were analyzed. The patient presentation, tumor management, and clinical course were compared between malignant and benign histotypes. Clinical and surgical variables that might influence event-free survival were considered. RESULTS Among the 78 children identified, PTTs were more likely to be malignant than benign; bronchial carcinoid tumor (n = 31; 40%) was the most common histological subtype, followed by inflammatory myofibroblastic tumor (n = 19; 25%) and mucoepidermoid carcinoma (n = 15; 19%). Regarding symptoms at presentation, wheezing (P = 0.001) and dyspnea (P = 0.03) were more often associated with benign growth, whereas hemoptysis was more frequently associated with malignancy (P = 0.042). Factors that significantly worsened event-free survival were age at diagnosis earlier than 112 months (P = 0.0035) and duration of symptoms lasting more than 2 months (P = 0.0029). CONCLUSION The results of this international study provide important information regarding the clinical presentation, diagnostic workup, and treatment of PTTs in children, casting new light on the biological behavior of PTTs to ensure appropriate treatments. LEVEL OF EVIDENCE NA Laryngoscope, 130:E243-E251, 2020.

Abstract
The treatment of pulmonary carcinoid has changed over the last decades. Although surgical resection is still the gold standard, minimally invasive endobronchial procedures have emerged as a parenchyma sparing alternative for tumors located in the central airways. This review was performed to identify the optimal treatment strategy for pulmonary carcinoid, with a particular focus on the feasibility and outcome of parenchyma sparing techniques versus surgical resection. A systematic review of the literature was carried out using MEDLINE, Embase and the Cochrane databases, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Two separate searches of publications in endobronchial and surgical treatment in patients with pulmonary carcinoid, were performed. Outcomes were overall survival, disease free survival, recurrence rate, complications, quality of life, and healthcare costs. Combining the two main searches for endobronchial therapy and surgical therapy yielded 3111 records. Finally, 43 studies concerning surgical treatment and 9 studies related to endobronchial treatment for pulmonary carcinoid were included. Assessment of included studies showed that lymph node involvement, histological grade, tumor location and tumor diameter were identified as poor prognostic factors and seem to be important for patients with pulmonary carcinoid. For patients with a more favorable prognosis, tumor location and tumor diameter are important factors that can help decide on the optimal treatment strategy. Centrally located small intraluminal pulmonary carcinoids, without signs of metastasis can be treated with minimally invasive alternatives such as endobronchial treatment or parenchyma sparing surgical resection. Patients with parenchyma sparing resections should be followed with long term follow up to exclude recurrence of disease. In a multidisciplinary setting, it should be determined whether individual patients are eligible for parenchyma sparing procedures or anatomical resection. Overall evidence is of low quality and future studies should focus on prospective trials in the treatment of pulmonary carcinoid.

Abstract
BACKGROUND Pulmonary carcinoids (PC) are histologically classified into typical carcinoid (TC) and atypical carcinoid (AC). The diagnosis of pulmonary carcinoid and possibly the differentiation between TC and AC could make a significant effect on the treatment planning as well as prognosis. Several studies have explored the utility of Ga-DOTA-Peptide (Ga-labelled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-peptide) and F-flurodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the evaluation of primary pulmonary carcinoids. Therefore, we performed a meta-analysis to evaluate the diagnostic accuracy and prediction efficiency of histological subtypes of these two imaging modalities in primary PC. METHODS Relevant studies were identified by searching PubMed, Web of Science, and EMBASE published from 2006 to 2016. Two authors extracted characteristics of patients and their lesions using predefined criteria. RESULTS Fourteen studies comprising 352 patients were included in this meta-analysis. The pooled sensitivity of Ga-DOTA-Peptide and F-FDG PET/CT in detecting pulmonary carcinoid were 90.0% (95% CI = 82.0-95.0%; P = .07; I = 49.6%) and 71.0% (95% CI = 66.0-76.0%; P < .001; I = 59.3%), respectively. An SUVmax ratio between Ga-DOTA-Peptide and F-FDG higher than the cutoff value of 4.28 was predictive of TC with 89.3% sensitivity and 100% specificity (AUC, 96.4%; 95% CI, 91.1-100%). The ratio of tumor uptake to atelectatic lung uptake was significantly higher for Ga-DOTA-peptide (2.5-91, mean 30.5 ± 28.1) than for F-FDG (0.3-10.3, mean 2.1 ± 2.3) (P < .001). CONCLUSIONS Both Ga-DOTA-peptide and F-FDG are highly sensitive in detecting pulmonary carcinoid, while Ga-DOTA-peptide is more sensitive than F-FDG (90.0% vs 71.0%). The SUVmax ratio was an accurate predictor of the histopathologic variety of the carcinoid tumor, and Ga-DOTA-peptide was better than F-FDG in cases with atelectasis.

Abstract
The incidence of stage I and II nonsmall cell lung cancer is likely to increase with the ageing population and introduction of screening for high-risk individuals. Optimal management requires multidisciplinary collaboration. Local treatments include surgery and radiotherapy and these are currently combined with (neo)adjuvant chemotherapy in specific cases to improve long-term outcome. Targeted therapies and immunotherapy may also become important therapeutic modalities in this patient group. For resectable disease in patients with low cardiopulmonary risk, complete surgical resection with lobectomy remains the gold standard. Minimally invasive techniques, conservative and sublobar resections are suitable for a subset of patients. Data are emerging that radiotherapy, especially stereotactic body radiation therapy, is a valid alternative in compromised patients who are high-risk candidates for surgery. Whether this is also true for good surgical candidates remains to be evaluated in randomised trials. In specific subgroups adjuvant chemotherapy has been shown to prolong survival; however, patient selection remains important. Neoadjuvant chemotherapy may yield similar results as adjuvant chemotherapy. The role of targeted therapies and immunotherapy in early stage nonsmall cell lung cancer has not yet been determined and results of randomised trials are awaited.

Abstract
The trachea and bronchus surgery is generally performed due to stenosis, traumatic injury, foreign body and tumors. Preoperative evaluation and anesthesia management are very important issues because of higher mortality and morbidity rates. Patients may be asymptomatic, but airway difficulties, hypoxia, stridor, cough, hemoptysis are common conditions in these patient population. The collaboration between the surgeon and the anesthesiologist is very substantial and necessary. Anesthetic techniques include various applications such as one lung ventilation, fiberoptic intubation, jet ventilation, and apneic oxygenation, general anesthesia with or without neuromuscular blockade. In this review, anesthesia management of the trachea and bronchus surgery is evaluated in the light of new knowledge.

Abstract
Inflammatory myofibroblastic tumor (IMT) is an uncommon solid tumor that was originally described in the lung. A 4-year-old girl was admitted to hospital with urticarial rash. On chest radiographs, an opacity was seen in the inferior zone of the left lung, and computed tomography showed a mass in the left lower lobe. Left lower sleeve lobectomy was performed, and the diagnosis was confirmed as IMT. Sleeve resection is the best option in lesions located in the mainstem bronchus or secondary carina. Herein, we present a rare case of IMT of the lung that was successfully treated with sleeve lobectomy. There have been fewer than 15 childhood cases of IMT reported in the literature, and the present 4-year-old patient is one of the youngest.

Abstract
BACKGROUND Paediatric tracheobronchial tumours are very rare, and pneumonectomy and lobectomy procedures are rarely indicated due to their surgical difficulties and high sequelae. Bronchoplastic techniques preserving lung parenchyma allow the resection and reconstruction of the main bronchi and carina. CASE PRESENTATION Here, we present a 6-year-old boy suffering from a carcinoid tumour of the right main bronchus which was successfully managed with a right upper sleeve lobectomy and a 4-year-old girl with an endobronchial carcinoid tumour narrowing the left main bronchus that received a sleeve resection of that bronchus. CONCLUSION Bronchoplastic techniques are widely used in adults, can be very successful in paediatric patients where the preservation of the lung parenchyma is more important.

Abstract
BACKGROUND Preoperative bronchoscopic tumour ablation has been suggested as a beneficial treatment for bronchopulmonary carcinoid tumours, although data regarding its effects and long-term outcome are lacking. METHODS In our case-matched cohort study with 208 patients with bronchopulmonary carcinoid tumours we investigated the role of preoperative bronchoscopic interventions before subsequent surgery and analysed the safety of this Procedure of Endobronchial Preparation for Parenchyma-sparing Surgery (PEPPS) based on metastasis and recurrence rates as well as survival data from 1991 to 2010. The subsequent surgery was classified into parenchyma-sparing procedures and classical lobectomies, bilobectomies and pneumonectomies. Data were obtained from the tumour registry and medical reports. Outcomes were the frequency of parenchyma-sparing surgery after bronchoscopic treatment as well as rates of metastasis, recurrence and survival. RESULTS 132 of 208 carcinoids were located centrally. Among them, 77 patients could be recanalised preoperatively. After bronchoscopic preparation, the rate of subsequent parenchyma-sparing surgery methods was higher (p=0.021). The effect was measured by the number of segments removed. The 10-year survival rate was 89% (typical carcinoids) and 68% (atypical carcinoids), respectively. After applying PEPPS, long-term survival was slightly higher (p=0.23). Metastasis and recurrence rates showed no relevant differences between the bronchoscopically treated or non-treated groups, or between the two types of surgery classes or between the PEPPS and non-PEPPS groups. CONCLUSIONS After preoperative bronchoscopic treatment, parenchyma-sparing surgery techniques can be applied more frequently. Furthermore, we detected no negative effects after PEPPS based on metastasis, recurrence and survival rates.

Abstract
BACKGROUND The purpose is to delineate the clinical and pathological characteristics of rare primary malignant pulmonary tumors in children. METHODS Utilizing the National Cancer Data Base (NCDB), we analyzed all children (≤ 18 years) with a primary malignant pulmonary tumor from 1998 to 2011 to identify factors associated with better survival. RESULTS Of 211 children identified, the most common histology was carcinoid tumor (n=133, 63%) followed by mucoepidermoid carcinoma (MEC) (n=37, 18%), squamous cell carcinoma (SCC) (n=19, 9%), adenocarcinoma (n=16, 8%), bronchoalveolar carcinoma (BAC) (n=4, 2%), and small cell carcinoma (SCLC) (n=2, <1%). Factors that significantly affected survival include histology, race, tumor size, lymph node status, and extent of surgery. Patients with MEC and carcinoid tumors had a better overall survival compared to patients with other histologies (p<0.0001). The 5-year overall survival for MEC and carcinoid tumors was 100% and 95% (95% CI 87-98), respectively, versus 50% (95%CI 1-91) for BAC, 28% (95%CI 9-52) for SCC, and 26% (95%CI 5-55) for adenocarcinoma. CONCLUSION The majority of pediatric patients with a primary malignant pulmonary tumor present with carcinoid tumor or MEC and have an excellent prognosis. Lung cancers which are common in adults, but rare in children, have a worse prognosis.

Abstract
BACKGROUND Surgery is the gold standard of lung carcinoid treatment. However, bronchoscopic treatment may provide a complete cure in selected patients. The aim of the study was to review the results of laser treatment of bronchial carcinoids and to compare the outcome after laser resection against the outcome after surgical resection. METHODS Seventy-three patients, 29 men and 44 women, median age 53 years (range, 23 to 78 y), with bronchial carcinoids were treated by surgical resection (n=48) or endobronchial ablation (n=25). Bronchoscopic treatment was also performed in 5 of 48 surgical patients as a part of the surgical treatment strategy. RESULTS Among 25 patients treated endoscopically, 16 were successfully treated with laser, whereas 9 were operated subsequently. One major complication was registered, as an inadvertent ventilation caused a nonfatal fire of the bronchoscope during Nd:YAG laser procedure. Forty-eight patients underwent surgical resection. Most of the patients underwent lobectomy and bilobectomy (30 and 5 patients, respectively). Four of the patients were dead by the end of the study, 1 was treated with laser, and 3 treated with surgical resection. The overall survival was 94.5% in the surgical group and 94.4% in the group treated with endoscopic ablation (P=0.9). None of the 69 survivors had any sign of recurrence on computed tomographic scans and bronchoscopy by the end of the study. CONCLUSIONS This is a retrospective study and no randomization has been performed. However, the results add evidence to the view that transbronchial laser treatment may be offered as a safe, stand-alone procedure in the treatment of typical carcinoid tumor in the central airways.

Abstract
We conducted a 16-year retrospective review of 31 cases of tracheobronchial carcinoid tumors treated in our institution between 1995 and 2011, to determine their characteristic features and outcome of management. There were 12 men and 19 women. The most common presenting symptoms were cough and hemoptysis (71%) with a mean duration of 4 years. Preoperative bronchoscopy confirmed the diagnosis in 80% of patients. Right-sided tumors accounted for 60% of cases. Most tumors arose from the mainstem bronchi. Histologic analysis revealed typical carcinoids in 28 cases and atypical carcinoids in 3. Surgical treatment was mainly radical resection (pneumonectomy in 19 patients). A parenchymal-preserving surgery (sleeve resection of left main bronchus and end-to-end anastomosis) was only possible in 2 cases. Mediastinal lymph nodes were involved in 30% of cases. Most patients had widespread extraluminal extension. Follow-up revealed recurrence in one patient. No deaths were recorded, and complications were mainly atelectasis and air leak. Radical resection remains the mainstay of surgical management of bronchial carcinoids in cases of late presentation with destroyed and bronchiectatic distal pulmonary parenchyma. Parenchymal-preserving surgery should only be carried out when indicated.

Abstract
Background Left main bronchus resection and reconstruction (LMBRR) is a complex surgical procedure indicated for management of inflammatory, benign and low grade malignant lesions. Its application provides maximal parenchymal sparing. Methods Out of 98 bronchoplastic procedures performed at the Authors' Institution in the 1995-2011 period, 4 were LMBRR. Indications were bronchial carcinoid in 2 cases, inflammatory pseudotumor in 1 case, TBC stricture in 1 case. All patients underwent preoperatively a rigid bronchoscopy to restore the airway lumen patency. At surgery a negative resection margin was confirmed by frozen section in the neoplastic patients. In all patients an end-to-end bronchial anastomosis was constructed according to Grillo. Results There were neither mortality nor major complications. Airway lumen was optimal in 3 patients, good in 1. Conclusion LMBRR is a valuable option for the thoracic surgeon. It maximizes the parenchyma-sparing philosophy, broadening the spectrum of potential candidates for cure. It remains a technically demanding procedure, to be carried out by an experienced surgical team. Correct surgical planning affords excellent results, both in the short and long term.

Abstract
Carcinoid tumors are the most common endobronchial tumors in the pediatric population, and represent a rare cause of airway obstruction. Clinical manifestations are unspecific, and diagnosis is often delayed due to low clinical suspicion. These tumors are considered low-grade malignant neoplasms, and their evolution is usually favorable after surgery. However, local recurrence and/or metastases can occur with both typical and atypical carcinoid tumors, justifying the need of prompt diagnosis and long-term follow-up.

Abstract
OBJECTIVES To investigate the clinical characteristics and treatment outcomes in Chinese pediatric and adolescent patients with primary tracheobronchial tumors by focusing upon the exploration of prognostic factors. METHODS A retrospective review of medical records collected from January 1996 through June 2009 was conducted within a single institution, inclusive of the total 19 treated pediatric and adolescent patients (3 benign tumors, 16 malignant tumors). A parallel comparison of adult cases with tracheobronchial tumor was performed to the pediatric and adolescent cases. RESULTS The chart review of pediatric and adolescent case reports revealed 19 cases with primary tracheobronchial tumors. Final pathologic diagnosis included 14 (73.68%) mucoepidermoid carcinoma (ME), 2 (10.53%) carcinoid tumor, 2 (10.53%) papillomatosis and 1 (5.26%) neurofibroma. Median age upon diagnosis was 12 years (range 4-18 years). Chest imaging revealed common abnormal radiographic atelectasis (12/19). Patients with localized disease received surgical tumor resection. There were a total of 8 (42.1%) sleeve resections, 4 (21.1%) resection of anatomically related lung parenchyma (1 bilateral lobectomies, 2 lobectomies, 1 pneumonectomy) and 7 local tumor resections. No surgery-related deaths or complications were observed. 16 patients (84.2%) remained disease free with a median follow-up of 70.5 months (range 44-168 months). CONCLUSIONS Our hospital data indicated a high incidence of ME, presenting the difference in the incidence rates between Chinese and western populations. Sleeve lobectomy provides efficient treatment with excellent prognosis among Chinese pediatric and adolescent patients.

Abstract
PURPOSE This study aimed to investigate the expression of the ErbB family of receptor tyrosine kinases in pulmonary typical carcinoid and atypical carcinoid tumors and to understand the role of epidermal growth factor receptor (EGFR) signaling in pulmonary carcinoid tumor proliferation. EXPERIMENTAL DESIGN Surgically resected typical carcinoid (n = 24) and atypical carcinoid (n = 7) tumor tissues were analyzed by immunohistochemical staining for EGFR, ErbB2, ErbB3, and ErbB4. Sequencing of tumor DNA of exons 18 to 21 of the EGFR gene and the KRAS gene was carried out. Biochemical analysis of lung carcinoid cell lines was used to investigate EGFR signal transduction and response to erlotinib inhibition. RESULTS The analysis showed that 45.8% of typical carcinoid and 28.6% of atypical carcinoid tumors express EGFR, 100% of the tumors lack expression of ErbB2, and 100% have moderate to intense staining for ErbB3 and ErbB4. Sequencing of tumor DNA of exons 18 to 21 of the EGFR gene revealed the absence of tyrosine kinase domain mutations in these tumors. Instead, 80.6% tumors harbored a synonymous single nucleotide polymorphism in exon 20. Because EGFR and KRAS mutations tend not to be present at the same time, we sequenced the KRAS gene from pulmonary carcinoid tumor DNA and found that 100% were wild-type. Using a lung carcinoid cell line that expresses EGFR, we found that erlotinib reduced proliferation by inhibiting EGFR signal transduction. CONCLUSIONS Our findings suggest clinical potential for the use of EGFR inhibitors in the treatment of patients with pulmonary carcinoid tumors, particularly for patients with EGFR-positive pulmonary carcinoid tumors not amenable to surgical resection.
