Immunotherapy has improved the prognosis of patients with advanced non-small cell lung cancer (NSCLC), but only a small subset of patients achieved clinical benefit. The purpose of our study was to integrate multidimensional data using a machine learning method to predict the therapeutic efficacy of immune checkpoint inhibitors (ICIs) monotherapy in patients with advanced NSCLC. We retrospectively enrolled 112 patients with stage IIIB-IV NSCLC receiving ICIs monotherapy.

Background: Thymic carcinoma (TC) is a rare type of a malignant tumor. The optimal treatment for Masaoka-Koga stage IVB TC patients is controversial due to the rarity of the disease. Chemotherapy is still the preferred option, but the outcomes are unsatisfactory.

Oligometastatic non-small-cell lung cancer (NSCLC) is potentially curable. Oligo-recurrence occurs with oligometastatic disease characterized by well-controlled primary lesion. The purpose of the present study was to explore the value of definitive local therapy (DLT) for extracranial single-organ oligorecurrent NSCLC.

Pulmonary sarcomatoid carcinoma (PSC) is an aggressive and poorly differentiated type of non-small cell lung carcinoma. Because of the rarity of PSC, the efficacy and toxicity of immunotherapy remain unclear. Hence, the aim of this study was to evaluate the efficacy and safety of immune checkpoint inhibitors (ICIs) for the treatment of advanced PSC.

We aimed to explore the treatment efficacy of first-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) for lung squamous cell carcinoma (SCC) patients and identify potential beneficial subgroups of EGFR-mutated lung SCC patients in this study. Between February 1st, 2013 and December 1st, 2021, 657 advanced lung SCC patients were enrolled at Zhejiang Cancer Hospital. Amplification refractory mutation system PCR or next-generation sequencing were used to detect gene abnormality.

Objectives: The 2015 World Health Organization classification defines pulmonary large-cell neuroendocrine carcinoma (LCNEC) as a high-grade neuroendocrine carcinoma. However, the clinical characteristics and prognostic factors of pure LCNEC and combined LCNEC remain unclear. Hence, we performed a multi-center retrospective study to compare the clinical outcomes of pure versus combined LCNEC.

Background: The thoracic radiotherapy (TRT) target volume for limited-stage small-cell lung cancer (SCLC) has been controversial for decades. In this report, the final results of a prospective randomized trial on the TRT target volume before and after induction chemotherapy are presented.

Methods: After 2 cycles of etoposide and cisplatin, patients arm were randomized to receive TRT to the postchemotherapy or prechemotherapy tumor volume in a study arm and a control arm.

In non-small cell lung cancer (NSCLC), driver gene alterations, such as , and , are usually mutually exclusive. Few clinical cases with co-existing fusion and de-novo amplification have been reported. In addition, the efficacy of crizotinib in Chinese patients with driver co-existing alterations is uncertain.

Background: ALK rearrangement-advanced NSCLC patients respond to crizotinib. ALK rearrangement is currently determined with RT-PCR. VENTANA IHC is a standard method to identify ALK protein overexpression in NSCLC; however, VENTANA IHC has rarely been used to determine the response to crizotinib in Chinese patients with NSCLC and ALK overexpression.

The most frequent epidermal growth factor receptor (EGFR) mutations of lung cancer include exon 19 in deletion and the exon 21 L858R mutation. And EGFR-tyrosine kinase inhibitor (TKI) as the standard first line treatment show good response to classical/sensitizing EGFR mutations. With the development of detection methods, some uncommon genomic mutation events such as exon 18-25 kinase domain duplications (KDD) and EGFR rearrangements (EGFR-RAD51 or EGFR-PURB) are found.

Preoperative elevation of serum C-reactive protein (CRP) is reportedly associated with poor prognosis in several types of cancer. This study investigated the role of serum CRP as a prognostic factor in early-stage esophageal squamous cell carcinoma (ESCC). The preoperative serum CRP levels were measured in 156 newly diagnosed pT1-2N0M0 patients using an enzyme-linked immunosorbent assay.

Background: Several clinical trials showed that erlotinib was effective after the failure of gefitinib in advanced non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the feasibility of erlotinib treatment after the failure of gefitinib based on the data from our hospital.

Methods: The clinical data of 20 patients with advanced NSCLC who were admitted to Shanghai Chest Hospital from August 2007 to December 2008 were retrospectively analyzed.

Background: To study the cost-efficacy of docetaxel and pemetrexed as single agents versus platinum-based combination agents in second-line treatment of stage IIIb or IV non-small cell lung cancer (NSCLC) patients by evaluating chemotherapeutic indexes and medical costs.

Methods: Treatment responses were evaluated by progression-free survival (PFS), overall survival (OS), hematological and gastrointestinal toxicities.

Results: Two hundred and seven stage IIIb or IV NSCLC patients were recruited to this clinical observation retrospective study.
