BACKGROUND: Peritoneal carcinomatosis is a rare clinical event in lung cancer and the prognosis is very poor. There are limited data on what factors predict peritoneal progression and affect the outcome. The aim of this study is to investigate investigate the factors associated with peritoneal carcinomatosis. METHODS: The patients with non-small cell lung cancer (NSCLC) from the Department of Medical Oncology and Radiation Sickness, Peking University Third Hospital were eligible for retrospective analysis between August 2010 and August 2018. Clinical factors such as age, gender, histology, pleural effusion and gene mutations with epidermal growth factor receptor/anaplastic lymphoma kinase/ROS proto-oncogene 1 receptor tyrosine kinase (EGFR/ALK/ROS1) were analyzed. Overall survival (OS) was calculated by the Kaplan-Meier method. RESULTS: 1.44% (12/836) patients in this study developed peritoneal carcinomatosis and 12 patients with adenocarcinoma had metachronous NSCLC diagnosis and PC. Malignant pleural effusion rates at baseline and at PC diagnosis were separately 50% (6/12) and 100.0% (12/12). Among the 12 patients, 9 patients harbored EGFR/ALK/ROS1 mutation. The outcome of patients with EGFR/ALK/ROS1 mutation was significantly better than that of patients without EGFR/ALK/ROS1 mutation, the mOS1 and mOS2 were separately 26.0 months and 6.0 months versus 10.0 months and 1.5 months (P<0.05). The mOS2 of patients with aggressive treatment after PC diagnosis was 6.0 months, significantly better than 1.0 month of patients with best supportive care (P<0.05). The mOS2 of the patients with angiogenesis inhibitors based-treatment after PC diagnosis was 8.5 months, significantly longer than that of patients with other treatments (P<0.05). CONCLUSIONS Adenocarcinoma and malignant pleural effusion are highly associated with peritoneal carcinomatosis in patients with advanced NSCLC. Aggressive treatment for lung cancer with PC is encouraged when possible. More patients with PC may benefit from the treatment strategies with angiogenesis inhibitors. Further prospective trials are urgently needed.

BACKGROUND: The incidence and the mortality of lung cancer rank first among all malignant tumors and it seriously affects human health. The common types of non-small cell lung cancer (NSCLC) are adenocarcinoma and squamous carcinoma with clinical research and more attention, while adenosquamous carcinoma is a rare pathological subtype of lung cancer, which clinical features and prognostic factors are not yet fully understood. The purpose of this study is to analyze the clinical features and prognosis of lung adenosquamous carcinoma, and construct a nomogram to predict the patients' prognosis. METHODS: We obtained the data of adenosquamous carcinoma patients diagnosed between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database of the United States, and compared their clinical features and prognosis with those of lung adenocarcinoma and lung squamous cell carcinoma patients in the same period. Then we used univariate and multivariate analyses to explore the independent prognostic factors of adenosquamous carcinoma. Finally, we constructed and validated a nomogram to visually predict the outcomes of lung adenosquamous carcinoma. RESULTS: 1,453 patients with lung adenosquamous carcinoma were finally included. Compared with patients with lung adenocarcinoma and lung squamous cell carcinoma, the distributions of lung adenocarcinoma patients in most of the variables were medium between lung adenocarcinoma and squamous cell carcinoma. The prognosis of adenosquamous carcinoma was better than that of lung squamous cell carcinoma, but worse than that of lung adenocarcinoma. Multivariate analysis showed that age, differentiation, tumor-node-metastasis (TNM), surgery, and chemotherapy were independent prognostic factors (all P were less than 0.001). We constructed a nomogram with a C-index of 0.783 (0.767-0.799). The distinction test and consistency test showed that the nomogram could predict the patient's prognosis effectively. CONCLUSIONS Lung adenosquamous carcinoma has unique clinical, pathological, and prognostic characteristics. Age, differentiation, T, N, M, surgery, and chemotherapy status are independent predictors of prognosis in patients with adenosquamous carcinoma. Our nomogram can efficiently predict the prognosis of patients.

BACKGROUND: Lung cancer is the leading cause of cancer-related deaths, patients with non-small cell lung cancer (NSCLC) usually have distant metastases, such as bone metastasis, brain metastasis, and lung metastasis. The purpose of this study was to explore the risk factors for bone metastasis in NSCLC patients. METHODS: A total of 176 cases of NSCLC were selected from May 2009 to May 2011, and patients were divided into two groups, namely the bone metastasis group and non-bone metastasis group. The general clinicopathological data of the two groups and analyzing the independent risk factors of bone metastasis were compared. RESULTS: In the general clinicopathological data of NSCLC patients. The thrombus or not and tumor-node-metastasis (TNM) stage were closely related to the occurrence of bone metastasis, and were statistically significant (all P<0.01). Prothrombin time, activated partial thromboplastin time, Fibrinogen, thrombin time, blood platelet, D-Dimer and alkaline phosphatase have significantly difference between the two groups (all P<0.05). Logistic regression analysis showed that fibrinogen, activated partial thromboplast in time, alkaline phosphatase, T4 phase, N3 phase and d-dimer were independent risk factors for bone metastasis in NSCLC patients. CONCLUSIONS Fibrinogen, alkaline phosphatase, T3, N2 stage and D-Dimer is the independent risk factors of bone metastases in patients with NSCLC.

OBJECTIVES: To investigate the clinical and pathological features of patients with unilateral sinonasal disease (USD). METHODS: A retrospective analysis was completed on 376 adult patients with USD from January 2015 to December 2016. Their presenting symptoms, nasal endoscope, CT scanning, and pathology were analyzed respectively. RESULTS: Among the 267 (71.01%) patients with inflammatory disease, there were 4 pathological types. And there were 8 pathological types in 60 (15.96%) patients with benign tumor. Of the 49 patients with malignant tumor, there were 15 pathological types which included squamous carcinoma, malignant melanoma, and lymphoma, as well as myoepithelial carcinoma and Mesodermal mesoderm. The onset age of inflammation group was younger than that of benign (<0.05) or malignant tumor groups (<0.05). The misdiagnosis rate was 8.33% in benign tumor (5/60), and 10.20% in malignant tumor (5/49). Nasal polyps was the most common misdiagnosis in the groups of benign and malignant tumor. CONCLUSIONS The pathology of adult patients with USD is complicated, and no specific clinical feature was found for distinguishing between benign and malignant lesions. The tumor took a quite proportion in adult patients with USD. Therefore, careful consideration should be taken before diagnosing patients with USD in order to reduce misdiagnosis rate.

In recent years, series of driver genes, such as EGFR, KRAS/NRAS, BRAF, PIK3CA, ALK and ROS1 and so on, have been found in non-small cell lung cancer (NSCLC) one after another with the development of molecular detecting technology. Targeted drugs bring benefits for these NSCLC patients with driver gene variations. However, some NSCLC did not have any known driver gene variations; we called it pan-negative lung cancer. In this paper, we summarize the concept, clinical pathological characteristics, the epidemiological characteristics, treatment and prognosis of pan-negative NSCLC.

Lung cancer is one of the most important malignant tumors in the world. The morbidity and mortality rank the first in all kinds of cancer. Long non-coding RNA (lncRNA) is at least 200 nt long and has no protein coding capacity. It plays an important role in the epigenetic regulation, cell cycle regulation, the regulation of cell differentiation, and many other life activities. The studies indicate that dysregulation of lncRNAs in non-small cell lung cancer (NSCLC) tissue and blood circulation is associated with the occurrence and development of cancer. The lncRNAs play an significant role in proliferation, differentiation, migration and apoptosis of the tumor cells. Explore the potential mechanism between lncRNAs and NSCLC is beneficial for the early diagnosis, target therpy and improve prognosis. Therefore, the study aims to demonstrate the latest studies on the lncRNAs related to occurence, diagnosis, therpy and prognosis of NSCLC. It can help to deeply understanding of lncRNA, and provide new ideas for the prevention of NSCLC.

BACKGROUNDLiver abscess is a serious complication following transcatheter arterial chemoembolization (TACE). Much attention has been paid to this condition as it may interfere with the treatment process and result in a poor prognosis of the patient. This study aimed to analyze the causes of liver abscess, a complication, after TACE for hepatic tumors and to summarize management approaches.

METHODSFrom June 2012 to June 2014, of 1480 consecutive patients who underwent TACE at our hospital, five patients developed liver abscess after TACE procedures for hepatic tumors. Of the five patients, each receiving conventional TACE, one underwent three sessions, two underwent two sessions, and the remaining two underwent one session of TACE. Demographic and clinical characteristics, together with management approaches and prognosis, were collected through a review of medical records.

RESULTSThese five patients were confirmed to have post-TACE liver abscess through clinical manifestations, laboratory, and imaging tests. After percutaneous drainage and anti-inflammatory treatments, the symptoms present in four patients with liver abscess significantly improved as evidenced by shrinkage or disappearance of the abscess cavity, and the patients recovered completely after sufficient drainage. The remaining patient experienced recurrent symptoms and abdominal abscess, achieved no significant improvement after treatment, and eventually died of severe infection and multiple organ failures.

CONCLUSIONSTACE must be implemented with extreme caution to avoid liver abscess. An effective management relies on an early diagnosis, prompt use of sufficient doses of appropriate antibiotics, and active implementation of abscess incision, drainage, and aspiration.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of patients with primary gastric adenosquamous cell carcinoma.

METHODSA total of 5 562 patients with gastric neoplasm were admitted in Tianjin Medical University Cancer Institute and Hospital from January 2001 to January 2011. Among them 42 patients were diagnosed as primary gastric adenosquamous cell carcinoma, accounting for 0.76% of all the patients. The clinicopathological and follow-up data of these 42 patients with primary gastric adenosquamous cell carcinoma were retrospectively analyzed, and Cox proportional hazard model was used to analyze the prognostic factors of gastric adenocarcinoma squamous cell carcinoma.

RESULTSAmong above 42 patients, 32 were male and 10 were female, with a male-to-female ratio of 3.2/1.0 and the average age was 63 years (range: 46 to 77 years). Five patients (11.9%) were confirmed as adenosquamous cell carcinoma by preoperative pathological examination, while other 37 patients were diagnosed as adenocarcinoma preoperatively. According to the 7th edition AJCC TNM classification system for gastric adenocarcinoma, 5 patients (11.9%) were in stage II(, 30 patients (71.4%) in stage III( and 7 patients (16.7%) in stage IIII(. The maximum tumor diameter was > 5 cm in 18 patients (42.9%). Borrmann type III(-IIII( was found in 29 patients (69.0%), and poorly differentiated (or undifferentiated) tumor was found in 32 patients (76.2%). Radical operations were performed in 31 patients (73.8%), the reasons of non radical operations included infiltration of pancreas in 3 patients, infiltration of radices mesocili transvers in 1 patient and classification of stage IIII( in 7 patients. Lymph node dissection was performed in 37 patients, 83.8% of them (31/37) was found with lymphatic metastases. Twenty-five patients received adjuvant chemotherapy except for 7 patients in stage IIII( and 10 patients who refused adjuvant chemotherapy. All the patients had an average survival time of 36.4 months and median survival time of 28.0 months, and the overall 1-, 3- and 5-year survival rates were 82.2%, 42.3% and 18.2% respectively. Univariate analysis revealed that tumor size (χ=4.039, P=0.044), Borrmann type (χ=18.728, P=0.000), tumor differentiation (χ=19.612, P=0.000), radical gastectomy (χ=41.452, P=0.000), lymph node metastasis (χ=9.689, P=0.002) and clinical stage (χ=26.277, P=0.000) were associated with postoperative survival. Multivariate analysis revealed that tumor differentiation (HR=10.560, 95%CI:2.263-49.281, P=0.003), radical gastrectomy (HR=4.309, 95%CI:1.311-14.168, P=0.016) and clinical stage (HR=2.392, 95%CI:1.022-5.600, P=0.044) were independent prognosis factors.

CONCLUSIONSPrimary gastric adenosquamous cell carcinoma is rare with poor prognosis. Radical gastrectomy is recommended. Tumor differentiation, radical gastrectomy and clinical stage are important indicators to evaluate prognosis of primary gastric adenosquamous cell carcinoma.

OBJECTIVE: This is a retrospective study aimed at clarifying the details of recurrence patterns and sites in patients with cervical cancer treated with definitive radiation therapy (RT). METHODS: Data were analyzed from consecutive patients, admitted to the University of Tokyo Hospital (Tokyo, Japan) between 2001 and 2013, who had received definitive RT, with or without chemotherapy, for International Federation of Gynecology and Obstetrics stages IB-IVA cervical cancer. RESULTS: One hundred and thirty-seven patients formed the patient cohort. The median follow-up period for surviving patients was 57.0 months. A complete response was achieved in 121 patients (88%). Of these, 36 (30%) developed a cancer recurrence during follow-up. The first sites of recurrence were located in intra-RT fields in nine, outside RT fields in 20, and both in seven patients. In the intra-RT field group, all patients showed a local recurrence, while no one experienced an isolated pelvic lymph node (PLN) recurrence. In the outside RT field group, the most frequent site of recurrence was lung (60%), and three-quarters of patients were free from intra-RT field recurrence until the last follow-up. Of the entire cohort, including 48 PLN-positive patients, only seven patients (5.1%) developed PLN persistence or recurrence, all in the common iliac, internal iliac, and/or obturator nodes, and all with another synchronous relapse. CONCLUSION: Local disease was a major type of intra-RT field recurrence, while PLN control was favorable even in initially PLN-positive patients. The predominance of outside RT field recurrence alone highlights issues concerning distant control, including the intensity enhancement of systematic therapy.

Many guidelines for hepatocellular carcinoma (HCC) have been published and updated globally. In contrast to other cancers, there is a range of treatment options for HCC involving several multidisciplinary care of the patient. Consequently, enormous heterogeneity in management trends has been observed. To support standard care for HCC, we systematically appraised 8 current guidelines for HCC around the world, including 3 guidelines from Asia, 2 from Europe, and 3 from the United States according to the selection criteria of credibility influence and multi-faceted. After a systematic appraisal, we found that these guidelines have both similarities and dissimilarities in terms of surveillance and treatment allocation recommendations due to regional differences in disease and other variables (diagnosis, staging systems) secondary to the lack of a solid, high level of evidence. In contrast to other tumors, the geographic differences in tumor biology (i.e., areas of increased hepatitis B prevalence) and available resources (organ availability for transplantation, medical technology, accessibility to treatment, health systems, and health resources) make it impractical to have an internationally universal guideline for all patients with HCC. Although Barcelona-Clinic Liver Cancer (BCLC) has long been dominant system for treatment-guiding staging of HCC, many Asia-pacific experts do not fully agree with its principle. The concepts of BCLC, for surgical resection or other locoregional therapy, are considered too conservative. Asian guidelines represent consensus about surgical resection and TACE indication for more advanced tumor.
