Special Issue Information
Dear Colleagues,
Thoracic Neuroendocrine Tumors (NETs) are classified into well-differentiated (low-grade typical carcinoids [TCs] and intermediate-grade atypical carcinoids [ACs]) and poorly differentiated (high-grade large cell neuroendocrine carcinoma LCNEC) or small cell lung carcinoma (SCLC) neuroendocrine carcinoma. Despite the increasing incidence of thoracic NETS, awareness [1] and the development of personalized approach therapies in these patients lag.
Well-differentiated carcinoids, as atypical carcinoid tumors in the lung, can recur and become challenging. Unfortunately, the guidelines regarding adjuvant therapies remain unclear, and current regimens' survival benefit is questionable [2]. There is a critical need to update the classification, diagnosis, and treatment of lung NETs. The development of molecular markers to provide evidence supporting the treatment of this underserved type of NET is an area of unmet need.
Effective systemic therapies for patients with advanced, progressive neuroendocrine lung tumors are very rare. However, recently, everolimus was associated with significant improvement in progression-free survival in patients with progressive lung neuroendocrine tumors [3]. Further drug development is needed.
To date, there is only one biomarker-based clinical trial, S1929, in the poorly differentiated NETs; SCLC that has recently completed enrollment for screening, that attempts to stratify patients with SCLC to receive PARP inhibitor based on SLFN11 that is expressed by more than half of patients with SCLC. Further knowledge of predictive factors and novel therapies is needed.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract: Background: Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of non-small cell lung cancer (NSCLC) with aggressive clinical nature and poor prognosis. New ways to effectively diagnose and treat PSC are evolving, with a promise of novel targeted therapeutics. In this study, we analyze demographics, tumor characteristics, treatment modalities, and outcomes of PSC. Methods: Data from the Surveillance, Epidemiology, and End Results (SEER) database was reviewed to analyze cases of pulmonary sarcomatoid carcinoma from 2000 to 2018. Results: A total of 5,259 patients with PSC were identified. Most patients were between 70-79 years of age (32.2%), males (59.1%) and Caucasians (83.7%). The male-to-female ratio was 1.45:1. Most tumors were between 1-7 cm in size (69.4%) and poorly differentiated (grade III) (72.9%). The overall 5-year survival was 15.6% (95% confidence interval (95% CI) = 14.4-16.9)), and the cause-specific 5-year survival was 19.7% (95% CI = 18.3-21.1). The five-year survival for those treated with each modality were as follows: chemotherapy, 19.9% (95% CI = 17.7-22.2); surgery, 41.7% (95% CI = 38.9-44.6); radiation, 19.1% (95% CI=15.1-23.5); and combination therapy, 24.8% (95% CI=17.6-32.7) respectively. On multivariable analysis, age, male gender, distant stage, tumor size, bone metastasis, brain metastasis, and liver metastasis were associated with increased mortality, and chemotherapy and surgery were associated with reduced mortality (p<0.001). Best survival outcomes were achieved with combination of surgery and chemotherapy or surgery only. Conclusion: PSC is a rare and aggressive subtype of NSCLC, usually affecting Caucasian males between 70-79 years of age. Male gender, older age, and distant spread were associated with poor clinical outcomes; treatment with chemotherapy and surgery were associated with better survival outcomes.
