[Progress in treatment for malignant pleural mesothelioma].

Malignant pleural mesothelioma (MPM) is a kind of invasive malignant tumor originated from pleural tissue. The incidence of MPM is not high in the population, but the prognosis is very poor. The median survival time is only about 12 months.

A Cost-Effective and Non-Invasive pfeRNA-Based Test Differentiates Benign and Suspicious Pulmonary Nodules from Malignant Ones.

The ability to differentiate between benign, suspicious, and malignant pulmonary nodules is imperative for definitive intervention in patients with early stage lung cancers. Here, we report that plasma protein functional effector sncRNAs (pfeRNAs) serve as non-invasive biomarkers for determining both the existence and the nature of pulmonary nodules in a three-stage study that included the healthy group, patients with benign pulmonary nodules, patients with suspicious nodules, and patients with malignant nodules. Following the standards required for a clinical laboratory improvement amendments (CLIA)-compliant laboratory-developed test (LDT), we identified a pfeRNA classifier containing 8 pfeRNAs in 108 biospecimens from 60 patients by sncRNA deep sequencing, deduced prediction rules using a separate training cohort of 198 plasma specimens, and then applied the prediction rules to another 230 plasma specimens in an independent validation cohort.

[The progress of Chinese surgery in 2017].

The article outlined the speeches of Surgeon Branch during the Annual Scientific Conference of Chinese Medical Association in 2018.From the perspectives of inheritance, innovation, standardization and improvement, it summarizes the major progress of Chinese surgery in 2017 and introduces the objectives and action plans of Chinese Medical Association Branch of Surgery this year.

[Thought of the present application situation and the future trends of minimally invasive surgery in colorectal cancer].

Laparoscopic surgery has been increasingly used in rectal cancer surgery. Though there are still some controversies, most of the research results support that the outcome is similar for rectal cancer patients with either laparoscopic or open surgery, in term of short-term such as safety and efficacy and long-term such as oncologic outcome. Standardization of laparoscopic training together with the comprehensive management concept are the prerequisites of laparoscopic rectal cancer surgery.

A piRNA-like Small RNA Induces Chemoresistance to Cisplatin-Based Therapy by Inhibiting Apoptosis in Lung Squamous Cell Carcinoma.

Lung cancer is the leading cause of cancer-related death worldwide. Although advanced drugs have benefitted patients, therapeutic success has largely been hampered because of rapid development of resistance. Here we report that PIWI-interacting RNA likes (piR-Ls), a novel type of functional sncRNAs, play key roles in chemoresistance to cisplatin (CDDP)-based chemotherapy in lung squamous cell carcinoma (LSCC).

[Low-dose methotrexate combined with vinorelbine for inoperable desmoid tumor: efficacy and the prognostic factors].

Objective: To characterize the clinical features of desmoid tumor, assess the efficacy of conservative chemotherapy for inoperable desmoid tumor and analyze the prognostic factors.

Methods: From August 2009 to December 2013, 52 patients with inoperable desmoid tumor were treated in our department and received chemotherapy with vinorelbine combined with low-dose methotrexate. The clinical data of the patients were analyzed retrospectively.
