Ann Diagn Pathol 2023; 66:152167. [PMID: 37329750 DOI: 10.1016/j.anndiagpath.2023.152167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 05/15/2023] [Accepted: 05/18/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVES Adenocarcinoma is the tumor group with the highest incidence among lung cancers with poor prognosis. Tumor budding (TB) is the migration of single tumor cells or small clusters of cells from the neoplastic epithelium to the invasive front of the tumor. Focal adhesion kinase (FAK) and survivin are considered as poor prognostic factors in several tumors. Hence, we investigated TB, FAK, and survivin expression in lung adenocarcinoma. METHODS The study included 103 cases of lung adenocarcinoma in the resection materials. In tumoral tissues; TB was counted and scored in one high-power field (HPF), as low if <5 in 1 HPF and high if ≥5 in 1 HPF. FAK and survivin were studied immunohistochemically. RESULTS The mean number of TB in 1 HPF is 3.96 ± 2.8. Low-grade TB was observed in 45 (43.7 %) and high-grade TB was observed in 58 (56.3 %) patients. There was a positive correlation between TB and pT stage (p = 0.017), clinical stage (p = 0.002), lymphovascular invasion (p = 0.001), and perineural invasion (p = 0.045). The 4-year survival rate in patients was 90 % in those with low-grade TB and 60 % in those with high-grade TB (p = 0.001). FAK and survivin expressions were significantly increased in tumors with high-grade TB (p < 0.05). CONCLUSION A significant correlation was found between the grade of TB and pT stage, clinical stage, lymphovascular and perineural invasion in lung adenocarcinoma. TB can be considered as a histological parameter showing poor prognosis. It is thought that high expression of FAK and survivin also affect the prognosis in these patients by increasing TB.

Clinicopathological and Prognostic Significance of Inhibitor of Apoptosis Protein (IAP) Family Members in Lung Cancer: A Meta-Analysis. Cancers (Basel) 2021; 13:cancers13164098. [PMID: 34439255 PMCID: PMC8392569 DOI: 10.3390/cancers13164098] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 08/07/2021] [Accepted: 08/11/2021] [Indexed: 12/25/2022] Open
Abstract
Lung cancer is the most common cause of cancer-related death worldwide. Approximately 85% is non-small-cell and 15% is small-cell lung cancer. The inhibitor of apoptosis proteins (IAPs) represent a heterogeneous family of anti-apoptotic proteins, some members of which have been reported to correlate with clinical outcome in lung cancer. We screened PubMed, Web of Science, and Scopus for studies that investigated the prognostic value and clinicopathological features of IAPs in lung cancer. Forty-five eligible studies with 4428 patients assessed the expression of the IAPs survivin, XIAP, livin, and BRUCE. The pooled hazard ratio (HR) of 33 studies that analyzed overall survival (OS) revealed a positive correlation between survivin expression and poor prognosis. Seven studies displayed a strong association between survivin and disease recurrence. Two studies that assessed the expression of XIAP and livin, respectively, proved a significant relationship of these IAPs with poor OS. Meta-analyses of clinicopathological variables revealed a significant association between survivin and T stage, UICC stage, the presence of lymph node metastasis, and grade of differentiation. In conclusion, high expression of distinct IAPs significantly correlates with prognosis in lung cancer. Therefore, lung cancer patients might benefit from a targeted therapy against specific IAPs.

Abstract
BACKGROUND The potential prognostic value of survivin is variably reported depending on the lung cancer stage. This study examines the correlation between tumor survivin expression before and after chemoradiation therapy, therapeutic response, and prognosis in stage III non-small cell lung cancer (NSCLC) patients who were treated with platinum-based chemoradiation therapy and surgery. METHODS This retrospective study included stage III NSCLC patients with adequate pre- and posttreatment tumor tissues. Tissues were stained using immunohistochemistry, and the degree of staining was scored. Clinical and biological variables were assessed using univariate and multivariate analyses to determine the prognostic relationship with overall survival (OS) and time to recurrence (TTR). RESULTS Fifty-three patients were enrolled. Tumor survivin expression in pretreatment tissues was determined in 47 patients (88.7%). The pretreatment survivin score was unrelated with TTR and OS (p = 0.249 and 0.601, respectively). There was no correlation between the pre- and posttreatment survivin scores (p = 0.309). Downregulated survivin and the posttreatment survivin score (0-1) after chemoradiation were significantly correlated with improved OS (p = 0.04 and p = 0.033, respectively). Age, downregulated survivin score, and posttreatment survivin score (0-1) were significant prognostic factors for survival according to the multivariate analysis. CONCLUSION Downregulated and low posttreatment survivin scores are prognostic in stage III NSCLC patients who receive platinum-based chemoradiation therapy followed by surgery regardless of the pretreatment survivin score. These results suggest that additional studies on the relationship between survivin and platinum-based chemoradiation therapy are warranted in NSCLC patients.

Abstract
Recent studies have shown that cancer immunotherapy could be a promising therapeutic approach for the treatment of cancer. In the present study, to identify novel tumor-associated antigens (TAAs), the proteins expressed in a panel of cancer cells were serologically screened by immunoblot analysis and the eukaryotic elongation factor 2 (eEF2) was identified as an antigen that was recognized by IgG autoantibody in sera from a group of patients with head and neck squamous cell carcinoma (HNSCC) or colon cancer. Enzyme-linked immunosorbent assay showed that serum eEF2 IgG Ab levels were significantly higher in colorectal and gastric cancer patients compared to healthy individuals. Immunohistochemistry experiments showed that the eEF2 protein was overexpressed in the majority of lung, esophageal, pancreatic, breast and prostate cancers, HNSCC, glioblastoma multiforme and non-Hodgkin's lymphoma (NHL). Knockdown of eEF2 by short hairpin RNA (shRNA) significantly inhibited the growth in four eEF2-expressing cell lines, PC14 lung cancer, PCI6 pancreatic cancer, HT1080 fibrosarcoma and A172 glioblastoma cells, but not in eEF2-undetectable MCF7 cells. Furthermore, eEF2-derived 9-mer peptides, EF786 (eEF2 786-794 aa) and EF292 (eEF2 292-300 aa), elicited cytotoxic T lymphocyte (CTL) responses in peripheral blood mononuclear cells (PBMCs) from an HLA-A*24:02- and an HLA-A*02:01-positive healthy donor, respectively, in an HLA-A-restricted manner. These results indicated that the eEF2 gene is overexpressed in the majority of several types of cancers and plays an oncogenic role in cancer cell growth. Moreover, the eEF2 gene product is immunogenic and a promising target molecule of cancer immunotherapy for several types of cancers.

Nuclear survivin and its relationship to DNA damage repair genes in non-small cell lung cancer investigated using tissue array. PLoS One 2013; 8:e74161. [PMID: 24066112 PMCID: PMC3774659 DOI: 10.1371/journal.pone.0074161] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2013] [Accepted: 07/29/2013] [Indexed: 11/19/2022] Open
Abstract
PURPOSE To investigate the predictive role and association of nuclear survivin and the DNA double-strand breaks repair genes in non-small cell lung cancer (NSCLC): DNA-dependent protein kinase catalytic subunit (DNA-PKcs), Ku heterodimeric regulatory complex 70-KD subunit (Ku70) and ataxia-telangiectasia mutated (ATM). METHODS The protein expression of nuclear survivin, DNA-PKcs, Ku70 and ATM were investigated using immunohistochemistry in tumors from 256 patients with surgically resected NSCLC. Furthermore, we analyzed the correlation between the expression of nuclear survivin, DNA-PKcs, Ku70 and ATM. Univariate and multivariate analyses were performed to determine the prognostic factors that inuenced the overall survival and disease-free survival of NSCLC. RESULTS The expression of nuclear survivin, DNA-PKcs, Ku70 and ATM was significantly higher in tumor tissues than in normal tissues. By dichotomizing the specimens as expressing low or high levels of nuclear survivin, nuclear survivin correlated significantly with the pathologic stage (P = 0.009) and lymph node status (P = 0.004). The nuclear survivin levels were an independent prognostic factor for both the overall survival and the disease-free survival in univariate and multivariate analyses. Patients with low Ku70 and DNA-PKcs expression had a greater benefit from radiotherapy than patients with high expression of Ku70 (P = 0.012) and DNA-PKcs (P = 0.02). Nuclear survivin expression positively correlated with DNA-PKcs (P<0.001) and Ku70 expression (P<0.001). CONCLUSIONS Nuclear survivin may be a prognostic factor for overall survival in patients with resected stage I-IIIA NSCLC. DNA-PKcs and Ku70 could predict the effect of radiotherapy in patients with NSCLC. Nuclear survivin may also stimulates DNA double-strand breaks repair by its interaction with DNA-PKcs and Ku70.

Abstract
Lung cancer is the leading cause of cancer deaths worldwide and one of the most common types of cancers. The limited success of chemotherapy and radiotherapy regimes have highlighted the need to develop new therapies like antitumor immunotherapy. CD8+ T-cells represent a major arm of the cell-mediated anti-tumor response and a promising target for developing T-cell-based immunotherapies against lung cancer. Lung tumors, however, have been considered to possess poor immunogenicity; even so, lung tumor-specific CD8+ T-cell clones can be established that possess cytotoxicity against autologous tumor cells. This paper will focus on the alterations induced in CD8+ T-cells by lung cancer. Although memory CD8+ T-cells infiltrate lung tumors, in both tumor-infiltrating lymphocytes (TILs) and malignant pleural effusions, these cells are dysfunctional and the effector subset is reduced. We propose that chronic presence of lung tumors induces dysfunctions in CD8+ T-cells and sensitizes them to activation-induced cell death, which may be associated with the poor clinical responses observed in immunotherapeutic trials. Getting a deeper knowledge of the evasion mechanisms lung cancer induce in CD8+ T-cells should lead to further understanding of lung cancer biology, overcome tumor evasion mechanisms, and design improved immunotherapeutic treatments for lung cancer.

Abstract
Among new biological markers that could become useful prognostic factors for non-small cell lung cancer (NSCLC). Survivin is one of the most commonly over-expressed oncogenes, however, its role in NSCLC remains controversial. We performed a systematic review of the literature with meta-analysis to clarify this issue. Electronic databases were used to identify published studies before August 2011. Pooled hazard ratio (HR) with 95 % confidence interval (95 % CI) was used to estimate the strength of the association of survivin expression with survival of NSCLC patients. Heterogeneity and publication bias were also assessed. Overall 29 relevant published studies including 2,517 lung cancer patients were identified from electronic databases. We found that overexpression of survivin in NSCLC patients might be a poor prognostic factor for survival 1.95 (95 % CI: 1.65-2.29; P < 0.001). Heterogeneity testing indicated that there was heterogeneity among studies. When stratified by histology types, the heterogeneity was absent. We should point out that the publication bias may partly account for the result, but the conclusion might not be affected deeply by the publication bias. When we accounted for publication bias using the trim and fill method, the results remained significant (HR = 1.71, 95 % CI: 1.44-2.02, P < 0.001), suggesting the stability of our results. Therefore, our study suggested that survivin overexpression had a poor prognosis value in patients with NSCLC.

Abstract
Resistance to cell death induction has been recognized as a hallmark of cancer. Increasing understanding of the underlying molecular events regulating different cell death mechanisms like apoptosis, endoplasmic reticulum stress, autophagy, necroptosis and others has opened new possibilities for targeted interference with these pathways. While conventional chemotherapeutic agents usually inhibit cell cycle progression, DNA replication or mitosis execution, novel agents like small molecule kinase inhibitors also target survival-related kinases and signaling pathways and contribute to overcome resistance to chemotherapy and apoptosis. Additionally, antibodies targeting cellular death receptors have been described to specifically target tumor cells only. This review briefly highlights the pathways involved in (apoptotic) cell death and summarizes the current state of development of specific modulators of cell death and how they can help to improve the tolerability of chemotherapy regimens and increase survival rates in patients with advanced cancer diseases.

Abstract
PURPOSE The potential prognostic value of survivin in resected non-small cell lung carcinoma (NSCLC) is variably reported. The objective of this study was to conduct a systematic review of literatures evaluating survivin expression in resected NSCLC as a prognostic indicator. METHODS Relevant literatures were identified using PubMed, EMBASE and Chinese Biomedicine Databases. We present the results of a meta-analysis of the association between survivin expression and overall survival (OS) in NSCLC patients. Studies were pooled and summary hazard ratios (HR) were calculated. Subgroup analyses and publication bias were also conducted. RESULTS We performed a final analysis of 2703 patients from 28 evaluable studies. Combined HRs suggested that survivin overexpression had an unfavorable impact on NSCLC patients' survival with no evidence of any significant publication bias (HR = 2.03, 95%CI: 1.78-2.33, Egger's test, P = 0.24) and no severe heterogeneity between studies (I² = 26.9%). Its effect also appeared significant when stratified according to the studies categorized by histological type, HR estimate, patient race, cutoff point (5%, 10%), detection methods and literature written language except for disease stage. Survivin was identified as a prognostic marker of advanced-stage NSCLC (HR = 1.93, 95%CI: 1.49-2.51), but not early-stage NSCLC (HR = 1.97, 95%CI: 0.76-5.14), in spite of the combined data being relatively small. CONCLUSION This study shows that survivin expression appears to be a pejorative prognostic factor in terms of overall survival in surgically treated NSCLC. Large prospective studies are now needed to confirm the clinical utility of survivin as an independent prognostic marker.

Abstract
Non-small cell lung cancer (NSCLC) is the biggest cancer killer in the United States and worldwide. In 2011, there are estimated to be 221,130 new cases of lung cancer in the United States. Over a million people will die of lung cancer worldwide this year alone. When possible, surgery to remove the tumor is the best treatment strategy for patients with NSCLC. However, even with adjuvant (postoperative) chemotherapy and radiation, more than 40% of patients will develop recurrences locally or systemically and ultimately succumb to their disease. Thus, there is an urgent need for developing superior approaches to treat patients who undergo surgery for NSCLC to eliminate residual disease that is likely responsible for these recurrences. Our group and others have been interested in using immunotherapy to augment the efficacy of current treatment strategies. Immunotherapy is very effective against minimal disease burden and small deposits of tumor cells that are accessible by the circulating immune cells. Therefore, this strategy may be ideally suited as an adjunct to surgery to seek and destroy microscopic tumor deposits that remain after surgery. This review describes the mechanistic underpinnings of immunotherapy and how it is currently being used to target residual disease and prevent postoperative recurrences after pulmonary resection in NSCLC.

Abstract
Survivin, an anti-apoptotic protein, was described as strongly expressed in human cancers including breast cancer. However, little is known about the association between Survivin variants (Survivin-2B, Survivin-ΔEx3, Survivin-3B, and Survivin-2α) and the other apoptotic-related genes. In this study, we analyzed the apoptosis gene signature of Survivin and its variant expression in breast cancer. Human Apoptosis Gene Arrays were used to screen genes that could be associated with Survivin variants. Expression of the five transcripts was measured by RT-PCR in 135 breast carcinomas and Cox survival analysis was analyzed according to the patient outcome. Significant associations between Survivin transcripts and apoptotic genes were found. Interestingly, Survivin-3B variant showed major inverse correlations with pro-apoptotic genes. In addition, in vitro results indicated that overexpression of Survivin-3B strongly inhibits 5-fluorouracil/epirubicin/cyclophosphamide-induced apoptosis in breast tumor cell lines. In breast carcinomas, uni- and multivariate analysis showed patients with high level of Survivin-3B expression had a shorter overall (P=0.030 and P=0.042 respectively), and disease-free (P=0.024 and P=0.009) survival. Our data suggest that Survivin-3B contributes to cell survival through the anti-apoptotic pathway and that its expression level could be an important factor in determining therapeutic strategies for breast carcinoma.

Abstract
Hu antigen R (HuR) is a member of the human family of embryonic-lethal, abnormal vision-like proteins, which serves as an mRNA-binding protein. In the cytoplasm, HuR can stabilize the mRNA of cyclooxygenase-2 (COX-2), an enzyme that catalyses the synthesis of prostaglandins and is associated with promotion of carcinogenesis and tumor cell resistance to apoptosis. Intracellular (cytoplasmic and nuclear) localization of survivin has a prognostic significance as an apoptosis inhibitor and a regulator of cell division in tumors. Patients with 151 squamous cell carcinomas and 93 adenocarcinomas underwent lobectomy or pneumonectomy with hilar and mediastinal lymph node sampling. Paraffin-embedded tumor sections were retrieved for evaluation of nuclear and cytoplasmic staining of survivin and HuR, and cytoplasmic staining of COX-2. In squamous cell carcinomas, COX-2 expression was correlated with a difference of survivin (cytoplasmic-nuclear; P=0.004), cytoplasmic HuR (P=0.018), total HuR (cytoplasmic+nuclear; P=0.009), and difference of HuR (P=0.020). COX-2 was inversely correlated with nuclear survivin (P=0.006). In a univariate analysis by log-rank test, survival was associated with cytoplasmic survivin (adenocarcinoma, P<0.001; squamous cell carcinoma, P=0.005), difference of survivin (adenocarcinoma, P<0.001; squamous cell carcinoma, P=0.014), and COX-2 (squamous cell carcinoma, P=0.001). Survival was inversely associated with nuclear survivin (adenocarcinoma, P=0.006, squamous cell carcinoma, P=0.014). In a multivariate survival analysis, cytoplasmic survivin (adenocarcinoma, P=0.002; squamous cell carcinoma, P=0.015) and COX-2 (squamous cell carcinoma, P=0.020) were determined as independent prognostic factors. Cytoplasmic HuR expression is associated with COX-2 expression in squamous cell carcinomas. The expression of COX-2 in squamous cell carcinomas, and cytoplasmic survivin in adenocarcinomas and squamous cell carcinomas could be useful independent prognostic markers.

Abstract
DNA damage, chromosomal abnormalities, oncogene activation, viral infection, substrate detachment and hypoxia can all trigger apoptosis in normal cells. However, cancer cells acquire mutations that allow them to survive these threats that are part and parcel of the transformation process or that may affect the growth and dissemination of the tumor. Eventually, cancer cells accumulate further mutations that make them resistant to apoptosis mediated by standard cytotoxic chemotherapy or radiotherapy. The inhibitor of apoptosis (IAP) family members, defined by the presence of a baculovirus IAP repeat (BIR) protein domain, are key regulators of cytokinesis, apoptosis and signal transduction. Specific IAPs regulate either cell division, caspase activity or survival pathways mediated through binding to their BIR domains, and/or through their ubiquitin-ligase RING domain activity. These protein-protein interactions and post-translational modifications are the subject of intense investigations that shed light on how these proteins contribute to oncogenesis and resistance to therapy. In the past several years, we have seen multiple approaches of IAP antagonism enter the clinic, and the rewards of such strategies are about to reap benefit. Significantly, small molecule pan-IAP antagonists that mimic an endogenous inhibitor of the IAPs, called Smac, have demonstrated an unexpected ability to sensitize cancer cells to tumor necrosis factor-alpha and to promote autocrine or paracrine production of this cytokine by the tumor cell and possibly, other cells too. This review will focus on these and other developmental therapeutics that target the IAPs in cancer.

Abstract
Inhibition of apoptosis is a critical step in tumorigenesis in many cancers, including Merkel cell carcinoma; however, the exact regulatory mechanisms are not fully understood. Survivin is an inhibitor of apoptosis that is undetectable in most terminally differentiated normal human tissues, strongly expressed in embryonic and fetal organs and is strongly expressed in many different human cancers. In this study, we investigated the expression of survivin in cutaneous Merkel cell carcinoma using immunohistochemistry and correlated the findings with long-term clinical follow-up. We collected and immunostained 19 cases of Merkel cell carcinoma with antibodies to survivin. The median patient age was 79 years, with an average follow-up of 17 months, and a male/female ratio of 7:11. All but one sample represented primary lesions and two cases were obtained from one patient. Clinical follow-up was obtained in 15 cases (79%). All 19 cases of Merkel cell carcinoma demonstrated strong immunoreactivity for survivin. Survivin protein was localized and classified into predominately nuclear (N=8) or cytoplasmic (N=4) compartments. A mixed pattern of survivin expression was also seen in three cases. Cases with a nuclear staining pattern were distinguished by an aggressive clinical course, with seven of eight patients developing metastases or dead of disease on follow-up. Furthermore, all of the cases with predominately cytoplasmic survivin localization (N=4) were free of disease on follow-up. Merkel cell carcinomas represent aggressive malignancies regulated by apoptotic pathways. We demonstrate that survivin, a protein with a dual role in inhibition of apoptosis and regulation of cellular proliferation is expressed in Merkel cell carcinoma. Moreover, nuclear subcellular localization of survivin in Merkel cell carcinomas may portend a poor prognosis and identification of these cases may assist clinical management.
