ABSTRACT

Immune checkpoint inhibitors (ICIs) have become an important means of cancer treatment, and their application in the clinic is becoming more and more widespread. The adverse reactions caused by ICIs are gradually recognized. Among them, immunotherapy-related diabetes is a rare adverse reaction and type 1 diabetes mellitusis common. With the wide application of ICIs combined with chemotherapy in lung cancer patients, patients with type 2 diabetes mellitus have gradually been discovered during the treatment. However, the effect of continued use of ICIs maintenance therapy on blood glucose and ICIs treatment process in these patients is still unclear. This article reports two cases of type 2 diabetes mellitus induced by immune checkpoint inhibitor combined with chemotherapy, one of whom converted to type 1 diabetes mellitus, in order to increase the understanding of immunotherapy-related diabetes.

ABSTRACT

Immune checkpoint inhibitors (ICIs) are widely used in clinic, and the incidence of rare adverse events are increasing. The aim of this paper is to better define the rare adverse effect of diabetes mellitus associated with ICIs. We report 2 cases of diabetes mellitus associated with ICIs. Literature review was conducted and we discussed the clinical presentation, potential mechanisms and suggestions for optimal management. Two patients were both elderly women, case 1 had increased blood glucose after 7 months of using Durvalumab, and cases 2 had diabetic ketoacidosis after 6 weeks of using Pembrolizumab. Both patients were administered exogenous insulin to control blood glucose. Case 1 has been treated with Durvalumab until now and case 2 discontinued using of Pembrolizumab. HLA genotypes and other factors may explain the risk factors of diabetes associated with ICIs in some individuals. Diabetes mellitus associated with ICIs is an uncommon but potentially life-threatening endocrine system adverse event, which requires doctors to be vigilant. The patients who use ICIs need to monitor blood glucose. If they have hyperglycemia, endocrinologists should be asked to assist in diagnosis and treatment.

ABSTRACT

Lung cancer is the most common malignancy tumor. Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancer. Human epidermal growth factor receptor-2 (HER2) is a tyrosine kinase receptor in ERBB/HER family, which activates downstream signal transduction with other family members such as epidermal growth factor receptor (EGFR). HER2 gene mutation is closely related to the progression of many epithelial cell cancers. Tumors with high expression of HER2 show strong metastasis and invasion ability, poor sensitivity to chemotherapy, and are prone to relapse. At present, lung cancer driven gene targeted therapy has made rapid progress. Although the frequency of HER2 gene mutation in NSCLC is lower than that of EGFR, its driving mechanism in lung cancer is clear and partial targeted therapy is effective, which may become a new standard treatment in the future. This review focuses on the research progress of HER2 gene mutation in the treatment of NSCLC.

ABSTRACT

Patients with sensitive epidermal growth factor receptor (EGFR) mutations often respond to tyrosine kinase inhibitors (TKIs), but acquired resistance will eventually develop. The most common mechanisms of acquired resistance include secondary EGFR mutation, MET amplification, and histologic transformation. Besides, gene fusions could also mediate the process of acquired resistance. Various gene fusions including rearranged during transfection (RET), v-raf murine sarcoma viral oncogene homolog B1 (BRAF) and anaplastic lymphoma kinase (ALK) could take place after TKIs resistance, the incidence of which is around 1%. The clinical cases and experiments both in vitro and in vivo have proved the role of gene fusions in EGFR-TKI resistance. The combination of EGFR inhibitors and gene fusion inhibitors might be an effective therapeutic method. The understanding of gene fusions at EGFR-TKI resistance may contribute to the subsequent diagnosis and treatment strategy.

ABSTRACT

Objective@#To investigate the effect of tumor deposits (TD) on the prognosis of patients with stage III colon cancer, and to explore whether TD number included into regional lymph node count can predict the prognosis more accurately.@*Methods@#A retrospective cohort study was carried out. Case inclusion criteria: (1) primary colon cancer; (2) undergoing colon cancer radical operation; (3) definite pathological diagnosis; (4) colon cancer stage III according to AJCC 8th edition; (5) complete follow-up data; (6) without preoperative neoadjuvant treatment. Clinicopathological data of 296 patients undergoing colon cancer radical operation from January 2005 to December 2008 in the Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively collected. The effect of TD and its amount on the prognosis was evaluated. Colon cancer TNM staging method based on the 8th edition of AJCC was compared with the modified TNM staging (mTNM) adjusted by the number of TD. The differences of the disease-free survival (DFS) and overall survival (OS) between groups were also examined. The Kaplan-Meier curve was used to analyze the survival, and prognostic factors were analyzed by Cox univariate and multivariate analyses.@*Results@#Among 296 patients with stage III colon cancer, 78 patients had TD. The median number of TD was 2 (1-10). Tumor T stage, N stage, vascular tumor thrombus and preoperative carcinoembryonic antigen (CEA) were associated with TD in patients with colon cancer (all P<0.05). The right hemicolon appears likely to have TD than left hemicolon, but the difference was not statistically significant (P=0.059). The median follow-up of the whole group was 71 (6-102) months. During the follow-up period, 129 patients (43.6%) had recurrence or metastasis, and 111 patients died (37.5%). The 5-year DFS in TD group was 44.9%, which was lower than that in the non-TD group (60.6%), with statistically significant difference (P=0.003). The 5-year OS in TD group was 50.0%, which was also lower than 67.0% in the non-TD group, and the difference was statistically significant (P=0.002). According to TD number, patients were divided into 3 groups: 1 TD (25 cases), 2-3 TD (32 cases), ≥4 TD (21 cases). The 5-year DFS in these 3 groups was 68%, 56.3%, and 0, respectively (P<0.001), and 5-year OS was 76%, 59.4%, and 4.8% respectively (P<0.001). Univariate analysis showed that TD presence (95% CI: 1.234-2.694, P=0.003) and TD number (95% CI: 3.531-14.138, P<0.001) were associated with the prognosis of patients with stage III colon cancer. At the same time, age, tumor N stage, tumor location, chemotherapy, and preoperative CEA elevation were also associated with the prognosis of stage III colon cancer patients (all P<0.05). Multivariate analysis revealed that TD presence (HR=1.957, 95%CI: 1.269-3.017, P=0.002) and TD number (HR=8.020, 95% CI: 3.414-18.842, P<0.001) were still independent risk factors for the prognosis of patients with stage III colon cancer.According to the TD number counted as metastatic lymph nodes, in 78 patients with TD, 24 patients were upstaged in N stage, and 16 patients upstaged from TNM stage IIIB to stage IIIC. For 16 stage IIIB cases with staging modification, 30 unadjusted stage IIIB cases with TD, and 148 stage IIIB cases without TD, the 5-year OS was 37.5%, 73.3% and 76.4%, respectively with significant difference (P<0.001). However, for 16 patients adjusted as stage IIIC (mTNM), 32 patients with unchanged stage IIIC with TD (TNM, AJCC 8th edition), and 63 stage IIIC cases without TD, the 5-year OS was 37.5%, 36.4%, and 41.3%, respectively without significant difference (P=0.707).@*Conclusions@#TD presence and TD number are independent risk factors for prognosis of stage III colon cancerpatients. TNM staging evaluation with lymph node number including TD number can predict the prognosis of patients more accurately.

ABSTRACT

Objective@#To observe the species distribution, clinical features, efficacy and safety of anti-fungus therapy in advanced elderly patients with fungemia.@*Methods@#Clinical data of patients aged 70 years and over with fungemia admitted into geriatric intensive care unit (GICU) of our hospital from Nov. 2012 to Nov. 2017 were retrospectively analyzed. The specie distribution, liver toxicity, differences in biochemical liver and renal functions before and after 28 days of treatment between the caspofungin group and the azole group (fluconazole plus voriconazole), and 28-d survival rate and its risk factors for death were analyzed.@*Results@#A total of 72 patients were enrolled, with a median age of 85.5 years (83, 90), a median score of Acute Physiology and Chronic Health Enquiry (APACHE-Ⅱ) of 25.5 (20.3, 31.5), a median score of Sequential Organ Failure Assessment (SOFA) 7 (4.0, 9.8). There were 33 patients (45.8%) with diabetes, 2 patients (2.8%) with hematological diseases, 44 patients (61.1%) with solid tumors and 18 patients (25.0%) with renal insufficiency. Thirty patients (41.7%) needed mechanical ventilation. The detection rate of Candida parapsilosis was 73.6% (53 cases), Candida famata 9.7% (7 cases), Candida tropicalis 5.6% (4 cases), Candida albicans 2.8% (2 cases), Candida glabrata 2.8% (2 cases) and others 5.6% (4 cases). The incidence rate of total liver toxicity was 23.6% after anti-fungus treatment. After 28 days of treatment, 29 patients survived in the caspofungin group (n=42) and 16 patients survived in the azole group (n=30). There were no significant differences in liver and renal function between the two groups before and after treatment. Logistic regression analysis showed that solid tumors (OR: 19.904, 95%CI: 1.944-203.808) and the median APACHE Ⅱ score were the independent risk factors for 28-day death in advanced patients with fungemia.@*Conclusions@#Fungemia is becoming more and more prominent in the GICU, which requires clinician’s constant attention in order to provide more basis for the treatment of fungemia in elderly patients.

ABSTRACT

Tyrosine kinase inhibitor (TKI) have been proved to be effective in the treatment of advanced non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) sensitive mutation, which is superior to chemotherapy. However, there are still some patients with sensitive mutations have primary drug resistance. It may be related to the coexistence of susceptible and resistant mutations of EGFR gene, downstream mutations of EGFR pathway, MET amplification and BIM deletion polymorphism. We present 2 cases of primary drug resistance and analyze the reasons.

ABSTRACT

With the development of sequencing technology, the detection rate of de novo T790M mutation is increasing. The emergence of the third generation of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) provide treatment opportunities. Secondary T790M mutation is often emphasized in clinic, but de novo T790M mutation is neglected. This review found that the incidence of de novo T790M mutation fluctuated greatly, which was mainly affected by sequencing techniques. The de novo T790M mutation is mainly low in mutation abundance, easy to combine with other gene changes, a poor predictor and prognostic factor and the efficacy of the first and second generation EGFR-TKIs is limited. The therapeutic value of osimertinib needs to be studied.

ABSTRACT

BRAF gene mutation is found in about 2%-4% of the patients with non-small cell lung cancer (NSCLC). This type of NSCLC is characterized by high malignancy, low efficacy of chemotherapy and poor prognosis. Although the combination treatment of BRAF inhibitor and MEK inhibitor has achieved remarkable results in advanced NSCLC patients with BRAF V600E mutation, which has been written into the National Comprehensive Cancer Network (NCCN) guidelines, severe side effects of the combination therapy are frequently observed. There isn't effective treatment strategy after drug resistance, and targeted therapy for non-V600E mutation patients is still lacking. In this paper, we summarized the researches on expression of immune markers in NSCLC patients with mutant BRAF and analyzed the studies on efficacy of immune checkpoint inhibitor (ICI), so as to provide more options for prolonging survival of the patients.

ABSTRACT

Objective To observe the clinical features of senile patients suffering from fungemia of Candida parapsilosis, and the effect and safety of antifungal therapy in treatment of this disease in geriatric intensive care unit (GICU). Methods The clinical data of patients with fungi positive either in peripheral blood culture or catheter culture admitted to the GICU of Tianjin Medical University General Hospital from November 2012 to June 2015 were retrospectively analyzed, of them 45 cases were of infection of Candida parapsilosis (parapsilosis group) and 15 cases infection of non-Candida parapsilosis (non-parapsilosis group). The clinical features of the two groups were collected, such as sex, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, timing of antifungal therapy, number of patients mechanical ventilation, concomitant disease, catheter-related infection, method of catheter-indwelling, levels of creatinine (Cr), hemoglobin (Hb), platelet count (PLT), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), etc.; the differences in above indicators were compared between the two groups; multifactor Cox-regression-analysis was used to analyze the risk factors that could affect the patients' prognosis; the patients' survival rates on 7, 14 and 28-day were calculated and compared between the two groups, and the therapeutic effects of different anti-fungal drugs on patients' survival rates and liver function damage were recorded and compared. Results The non-parapsilosis group had a higher rate in mechanical ventilation than parapsilosis group [73.3% (11/15) vs. 33.3% (15/45), P < 0.05], and in the comparisons of other clinical features, there were no statistical significant differences between the two groups (all P > 0.05). There were no statistical significant differences in survival rates in the duration of 7, 14 and 28 days between the two groups[7 days: 82.2% (37/45) vs. 66.7% (10/15), 14 days: 75.6% (34/45) vs. 60.0% (9/15), 28 days: 66.7% (30/45) vs. 46.7% (7/15), all P > 0.05]. When the patients in parapsilosis group treated with echinocinomycin were compared with those treated with azolol, no statistical significant differences were found between the 2 types of therapy in the survival rates in the duration of 7, 14, and 28 days after treatment [7 days: 100.0% (23/23) vs. 82.4% (14/17), 14 days: 91.3% (21/23) vs. 76.5% (13/17), 28 days: 78.3% (18/23) vs. 70.6% (12/17), all P > 0.05]. Multifactor Cox-regression-analyses showed:diabetes [odds ratio (OR) = 0.268, 95% confidence interval (95%CI) = 0.077 - 0.928, P = 0.038), infection of Candida parapsilosis (OR = 0.260, 95%CI = 0.072 - 0.946, P = 0.041), APACHE Ⅱ score (OR = 1.241, 95%CI = 1.051 - 1.466, P = 0.011) and SOFA score (OR = 1.405, 95%CI = 1.005 - 1.966, P = 0.047) were the risk factors affecting the prognosis of the patients. When the patients in parapsilosis group treated with echinocinomycin were compared with those treated with azolol, there were no statistical significant differences in incidences of aggravation of liver damage and newly developed liver damage (aggravation of liver damage: 18.8% vs. 21.0%, newly developed liver damage: 6.2% vs. 10.5%, both P > 0.05). Conclusion The patients with fungemia in GICU are mainly the infection of Candida parapsilosis, and diabetes, infection of parapsilosis, APACHE Ⅱ score and SOFA score are the risk factors affecting the prognosis of the patients.

ABSTRACT

Targeted therapy is one of the major treatment modalities in advanced non-small cell lung cancer (NSCLC) with sensitive driver gene mutations. BRAF is considered a promising oncogenic driver in NSCLC after the discovery of epidermal growth factor receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) fusion and ROS1 rearrangement. BRAF V600E mutation accounts for more than half of BRAF mutations, which is a potential therapeutic target for advanced NSCLC. This review aims to summarize the advancements of BRAF gene mutation and targeted therapy for BRAF mutation in NSCLC.

ABSTRACT

Molecular target therapy is one of the most popular field of non-small cell lung cancer (NSCLC) treatmnet. Epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) rearragement are the most important two oncogenic drivers in NSCLC, early studies suggested that EGFR mutations and ALK rearrangements are mutually exclusive, but isolated cases or small sample research with concomitant EGFR and ALK alterations have been constantly reported. The co-occurrence of EGFR mutations and anaplastic lymphoma kinase (ALK) rearrangements constitutes a rare molecular, the frequency of EGFR/ALK co-alterations was about 1%, however, little has been known about clinicopathologic feature and treatment. This review summarized published case report, EGFR and ALK alterations are common in female, Asian origin, never smoker, IV stage, and denocarcinomas. First-line treatment can choose EGFR or ALK tyrosine kinase inhibitors (TKIs). However, studies about the origin and resistance mechanism in EGFR/ALK co-alterations are little, require more experimental and clinical research.

ABSTRACT

BACKGROUND@#Chemotherapy is the most important method for cancer treatment. However, chemotherapy induced nausea and vomiting (CINV) has a profound effect on patients. In recent years, there have been new antiemetic drugs, such as aprepitant. We review the curative effect of aprepitant with tropisetron and dexamethasone for prevention of nausea and vomiting in patients receiving Cisplatin chemotherapy.@*METHODS@#Observation is divided into three stages. Whole study phase (0-120 h after chemotherapy administration), acute phases (0-24 h), and delayed phase (24 h-120 h). The primary endpoints were complete response (CR) and complete prevention (CP) during the three different study phase.@*RESULTS@#In the whole study phase, 86.02% of patients achieved CR; in acute phases and delayed phases were 89.25%, 87.1%, respectively. CP were 46.22%, 83.87%, 45.16%, respectively. Anti-CINV effect was significantly associated with age distribution (P=0.008).@*CONCLUSIONS@#Aprepitant with tropisetron and dexamethasone prevented effectively CNIV for patients receiving Cisplatin chemotherapy. This combination could improve the quality of life and the compliance of patient with chemotherapy.

ABSTRACT

Small cell lung cancer (SCLC), which accounts for about 15% of lung cancer cases, is an aggressive disease characterized by rapid growth and early widespread metastasis. Despite sensitive to chemotherapy and radiotherapy, SCLC is vulnerable to get resistant and has high recurrence rates. In recent years, immunotherapy has shown good antitumor activity, especially programmed death receptor-1/ligand-L1 (PD-1/L1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) Checkpoint inhibitors have changed the pattern of tumor treatment, and SCLC has high immunogenicity, high mutation load and other favorable immune factors, so immuno-checkpoint inhibitors may become an important breakthrough in SCLC treatment. This article will briefly review the clinical research of immunotherapy for small cell lung cancer.

ABSTRACT

Objective To discuss the serum value of human epididymis protein 4(HE4) in the diagnosis of lung can-cer and to analyse the serum levels of HE4 in different pathological types and TNM staging of lung cancer patients. Meth-ods Forty-seven patients with lung cancer and thirty-one healthy controls were selected to join this study. According to various pathological types and TNM staging, the selected lung cancer patients were divided into different subgroups under the two categories. The serum HE4 levels were compared between subgroups. ROC curves of serum HE4 level and serum CEA level were drawn for the diagnosis of lung cancer with the pathological diagnosis as the golden standard. Results There was significantly higher level of serum HE4 in lung cancer group[(253.47±170.03) pmol/L] than that of healthy group [(84.09±51.03) pmol/L](t=5.365). There were no significant differences in serum levels of HE4 between different pathological subgroups of lung cancer patients [non-small cell carcinoma group (241.34±161.81) pmol/L vs small cell carcinoma group (293.5±198.76) pmol/L, t=0.847;squamous cell carcinoma group (304.29±287.61) pmol/L, adenocarcinoma group (224.39± 122.15) pmol/L and small cell carcinoma group F=0.969;and different TNM staging subgroups [ (stageⅠ~Ⅲgroup (255.27± 183.04) pmol/L vs stageⅣgroup (288.16±216.49) pmol/L, t=0.528]. Compared with ROC curves of serum HE4 and serum CEA,the area under the curve (AUC) of serum HE4 (0.902) was larger than that of serum CEA(0.765),( P>0.001). When the serum level of HE4 was 149.145 pmol/L, the sensitivity and specificity in the diagnosis of lung cancer were 72.3% and 90.3%. When the serum level of CEA was 4.685μg/L, the sensitivity and specificity in the diagnosis of lung cancer were 57.4%and 83.9%. Conclusion The serum level of HE4 is a sensitive and specific tumor marker in lung cancer. There are no significant differences in the serum levels of HE4 between different pathological types and different TNM staging in lung cancer patients. The detection of serum levels of HE4 are useful for the diagnosis of lung cancer.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Fourty years ago, Tokuhata and Lilienfeld provided the first epidemiologic evidence of familial aggregation of lung cancer. Familial aggregation and increased familial risk for lung cancer have been reported in several studies, subsequently. But the results are not consistent with each other. The aim of this study is to further explore the relationship between family history of lung cancer and lung cancer risk.</p><p><b>METHODS</b>By searching PubMed, CENTRAL, CBM, CNKI and VIP, we collected both domestic and overseas published documents before November, 2009 on family history of lung cancer and lung cancer risk. RevMan version 4.2 was used to perform meta-analysis on the case-control study results, the combined odds ratio (OR) and the 95% confidence interval (CI) were calculated as well.</p><p><b>RESULTS</b>Twenty-eight publications were included into the combined analysis, which indicated that the lung cancer risk of the probands' first-degree relatives was 1.88 times higher than that of their controls' (P < 0.001). In the sub-study, compared with the controls' father mother and siblings, the OR of the probands' father mother and siblings was 1.62 (P < 0.001), 1.96 (P < 0.001) and 1.92 (P < 0.001), respectively. For smoking status, lung cancer risk in first-degree relatives of smoking probands was 1.73 (P < 0.001) times higher than that of their corresponding controls'. And for non-smoking subjects the lung cancer risk was 1.42 (P = 0.02) times higher in proboands' first-degree relatives. For gender categories, lung cancer risk in first-degree relatives of female probands was 1.89 (P < 0.001) times higher than that of their corresponding controls'. And for male subjects, the lung cancer risk was 1.99 (P < 0.001) times higher in proboands' first-degree relatives.</p><p><b>CONCLUSION</b>Lung cancer risk was increased in probands' first-degree relatives, and obvious familial aggregation of lung cancer was observed in this study.</p>
