Nomogram based on CMTM6 expression and clinical characteristics to predict postoperative overall survival in patients with hepatocellular carcinoma.

BACKGROUND: The purpose of this study was to investigate the expression of CMTM6 in HCC tissues and its prognostic value, and to try to develop a nomogram prognostic model based on CMTM6. METHODS: In this retrospective study, immunohistochemical (IHC) staining was performed in 178 patients who underwent radical hepatectomy in the same surgical team. R software was used to construct the nomogram model. The Bootstrap sampling method was used for internal validation. RESULTS: CMTM6 is significantly expressed in HCC tissues and is closely associated with decreased overall survival (OS). PVTT (HR = 6.2, 95% CI: 3.06 12.6, P<0.001), CMTM6 (HR=2.30, 95% CI: 1.27 4.0, P=0.006) and MVI (HR=10.8, 95% CI: 4.19-27.6, P<0.001) were independent predictors of OS. The nomogram combined with CMTM6, PVTT and MVI was more predictive than the traditional TNM scoring system, and the prediction effects of 1-year and 3-year OS were accurate. CONCLUSIONS: The prognosis of a patient may be predicted using high levels of CMTM6 expression in HCC tissues, and the nomogram model including CMTM6 expression has the best predictive ability.

Low pretreatment prognostic nutritional index predicts poor survival in breast cancer patients: A meta-analysis.

BACKGROUND: Prognostic nutritional index (PNI), as an indicator of nutritional immune status, has been shown to be associated with therapeutic effects and survival of solid tumors. However, the prognostic role of PNI before treatment in human breast cancer (BC) is still not conclusive. Hence, we performed this meta-analysis to assess the value of it in prognosis prediction for BC patients. MATERIALS AND METHODS: We searched PubMed, Embase, Web of Science and EBSCO to identify the studies evaluating the association between PNI and survival such as overall survival (OS), disease-free survival (DFS) of BC, and computed extracted data into hazard ratios (HRs) for OS, DFS and clinicopathological features with STATA 12.0. RESULTS: A total of 2322 patients with BC from 8 published studies were incorporated into this meta-analysis. We discovered that low pretreatment PNI was significantly associated with worse OS, but not with DFS in BC patients. In stratified analyses, the result showed that decreased PNI before treatment was remarkably related with lower 3-year, 5-year, 8-year and 10-year OS, but not with 1-year survival rate in BC. In addition, although reduced PNI could not impact 1-year, 3-year or 5-year DFS, it considerably deteriorated 8-year and 10-year DFS in patients. CONCLUSION: Low pretreatment PNI deteriorated OS, 8-year and 10-year DFS in BC patients, implicating that it is a valuable prognostic index and improving the nutritional immune status may offer a therapeutic strategy for these patients.

Elevated baseline circulating platelet-to-lymphocyte ratio and survival in initial stage â £ gastric cancer patients: A meta-analysis.

BACKGROUND: Systemic inflammatory response (SIR) plays important roles in initiation, promotion and progression of tumor. However, the prognostic role of baseline circulating platelet-to-lymphocyte ratio (PLR) (known as a marker of SIR) in human initial stage Ⅳ gastric cancer (GC) remains controversial. Hence, we performed this meta-analysis to assess the value of it in prognosis prediction for these patients. MATERIALS AND METHODS: We searched PubMed, Embase and EBSCO to identify the studies and computed extracted data with STATA 12.0. RESULTS: A total of 3025 patients with initial stage Ⅳ GC from 13 published studies were incorporated into this meta-analysis. We found that elevated baseline circulating PLR was significantly associated with decreased overall survival (OS), but not with progression-free survival (PFS) in stage Ⅳ GC patients. However, in stratified analyses, high PLR was only associated with worse 1-year and 2-year OS, but not with 3-year or 4-year OS; In addition, it was considerably related with reduced 6-month PFS, but not with 1-year or 2-year PFS. Moreover, high PLR markedly correlated with peritoneal metastasis of GC. CONCLUSION: Elevated baseline circulating PLR decreased 1-year OS and 6-month PFS in initial stage Ⅳ GC patients, implicating that it is a valuable prognostic index for these patients and modifying the inflammatory responses may have a potential for effective treatment.

LAG-3+ tumor-infiltrating lymphocytes ameliorates overall survival in triple-negative breast cancer patients.

Purpose: Immune checkpoint molecule lymphocyte-activating gene-3 (LAG-3), which is expressed on active lymphocytes, has proven to be associated with immunosuppression and cancer progression in a variety of solid tumors. However, the role of LAG-3+ lymphocytes in human breast cancer (BC) is still not conclusive. We therefore performed a meta-analysis to clarify the role of these cells in prognosis prediction for BC. Methods: We searched PubMed, Embase, and EBSCO to identify the studies evaluating the association of LAG-3+ lymphocyte infiltration and overall survival (OS) and/or disease-free survival (DFS) in BC patients, then combined extracted data with STATA 12.0. Results: Eight published studies involving 5,859 BC patients were incorporated into this meta-analysis. We noted that a high number of LAG-3+ tumor-infiltrating lymphocytes were not appreciably associated with OS and DFS in BC patients. Strikingly, in stratified analyses based on the molecular type of BC, LAG-3+ lymphocyte infiltration was remarkably associated with better OS rather than DFS in triple-negative breast cancer (TNBC), whereas it significantly influenced neither OS nor DFS in Her2-positive BC. However, an increased density of these lymphocytes indicated a trend for better OS in Her2-positive BC. In addition, we found that LAG-3+ lymphocyte infiltration was also remarkably associated with prolonged OS in Her2-positive BC patients when they were measured by immunohistochemistry (IHC). In addition, an elevated number of these lymphocytes did not correlate with pathological complete response rate or clinicopathological features including lymph node metastasis. Conclusion: The infiltration of LAG-3+ lymphocytes ameliorates OS in TNBC and Her2-positive BC, implicating that it is a valuable prognostic biomarker, and applications of anti-LAG-3 antagonists may possibly be not a promising therapeutic strategy for human BC especially for TNBC.

Impact of Lin28 on lymph node metastasis in papillary thyroid carcinoma.

Lin28 is involved in the progression of several types of tumors. Data collected from clinical trials have suggested that Lin28 expression is correlated with poor prognosis in thyroid carcinoma. The present study was conducted to investigate the association between Lin28 expression and the clinicopathological parameters of papillary thyroid carcinoma (PTC). Accordingly, the clinical data and diagnostic results from 237 patients with PTC were collected. Immunohistochemical staining was performed to evaluate the Lin28 expression levels in thyroid tissue samples. Associations between the expression levels and clinicopathological parameters were evaluated. Lin28 was expressed in 96/237 (40.5%) of PTC specimens. Compared with patients with no Lin28 expression, patients with expression had higher rates of lymph node metastasis (P<0.001) and larger tumors (P=0.011). Multivariate analysis revealed that Lin28 was associated with lymph node metastasis. Next, bioinformatics analysis was performed based using the Gene Expression Omnibus database and The Cancer Genome Atlas database. Lin28 expression was associated with aggressive tumor characteristics, such as lymph node metastasis and larger tumors. In conclusion, the present study revealed that Lin28 expression served as a risk factor for lymph node metastasis. Accordingly, Lin28 expression may be used as a prognostic marker to predict lymph node metastasis in patients with PTC. In addition, Lin28 may serve as a therapeutic target in the management of this tumor type, which may help improve patient outcomes.

Cellular immunotherapy plus chemotherapy ameliorates survival in gastric cancer patients: a meta-analysis.

The efficacy of cellular immunotherapy plus chemotherapy in treatment of gastric cancer (GC) remains inconsistent even controversial. Hence, we performed a meta-analysis to better comprehend the clinical value of cellular immunotherapy plus chemotherapy for GC patients. We searched PubMed, Embase and EBSCO databases to identify the studies evaluating the association of cellular immunotherapy plus chemotherapy and overall survival (OS) and/or disease-free survival (DFS) in patients with GC, and then combined relevant data into hazard ratios (HRs) for OS, DFS and clinicopathological features such as TNM stage, etc. with STATA 12.0. Eleven studies with 1244 patients were included in this meta-analysis. We found that cellular immunotherapy plus chemotherapy remarkably improved overall survival (OS) and diseases-free survival (DFS) as compared to the chemotherapy for GC patients. In subgroup analyses, pooled data showed that the combined therapy was significantly associated with better 3-year and 5-year survival rate, but not with 1-year survival rate of patients; the application of cellular immunotherapy based on either CIK or DC-CIK cells could enhance survival as well as NK, γδT and CIK cells-based immunotherapy. More importantly, the addition of cellular immunotherapy considerably improved OS and DFS only in patients with stage III rather than stage II. In addition, we also discovered that the combined therapy did not cause intolerable side effects to patients. Cellular immunotherapy plus chemotherapy ameliorates survival in GC, especially in patients with stage III, implicating that it is a valuable therapeutic strategy for these patients.

Management of a metal foreign body entering the thyroid via the esophagus: a case report.

The entry of a metallic foreign body into the thyroid gland via the esophagus is a rare occurrence, with no previously reported cases. We present a 42-year-old woman who was admitted to hospital with right-sided neck pain, reporting that she had inadvertently swallowed a fish bone. She underwent laryngoscopy, which showed no fish bone in the throat, and no obvious bleeding in the bilateral tonsils and pear-shaped fossa. X-ray examination showed a needle-shaped foreign body in the neck, and a computed tomography scan of her neck showed a 0.1-cm diameter, 2.0-cm long foreign body in the right thyroid. She underwent emergency surgery and a needle of the corresponding size was found in the thyroid gland. This case demonstrates the importance of adequate preoperative assessment and an appropriate surgical approach for thyroid metallic foreign bodies.
