[PMID: 37033050 PMCID: PMC10073750 DOI: 10.3389/fpubh.2023.1120671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 03/03/2023] [Indexed: 04/11/2023] Open
Abstract
Background There is limited research on the incidence of secondary lung cancer (SLC) after radiotherapy (RT) for oral cavity cancer (OCC). Therefore, we investigated the association between RT for OCC and the risk of SLC and the overall survival of these patients. Methods Patients diagnosed with OCC between 1975 and 2015 were selected from the Surveillance, Epidemiology, and End Results database. The cumulative incidence of SLC, relative risk (RR) of RT vs. no RT (NRT), standardized incidence ratios (SIR), and survival outcomes were assessed. Results A total of 10,936 patients with OCC were included. Of these, 429 (3.92%) patients developed SLC, where 136 (5.02%) received RT and 293 (3.56%) did not. The cumulative incidence of SLC during follow-up was 6.89% and 4.84% in the RT and NRT patients, respectively. RT was associated with a higher risk of SLC. In the subset analysis, the results showed that a higher risk of developing SLC among patients with index OCC in most subgroups. Dynamic RR and SIR revealed a decreased risk of SLC with increasing latency time. No difference was observed in the 10-year survival rates for patients with SLC who received RT or not or compared with primary lung cancer. Conclusion RT was associated with a higher risk of SLC, and patients diagnosed with OCC could be followed for 5-10 years after diagnosis.

Cancers (Basel) 2020; 12:cancers12030732. [PMID: 32244899 PMCID: PMC7140062 DOI: 10.3390/cancers12030732] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 03/05/2020] [Accepted: 03/16/2020] [Indexed: 12/27/2022] Open
Abstract
For the treatment of early and locally advanced glottic laryngeal cancer, multiple strategies are available. These are pursued and supported by different levels of evidence, but also by national and institutional traditions. The purpose of this review article is to compare and discuss the current evidence supporting different loco-regional treatment approaches in early and locally advanced glottic laryngeal cancer. The focus is kept on randomized controlled trials, meta-analyses, and comparative retrospective studies including the treatment period within the last twenty years (≥ 1999) with at least one reported five-year oncologic and/or functional outcome measure. Based on the equipoise in oncologic and functional outcome after transoral laser surgery and radiotherapy, informed and shared decision-making with and not just about the patient poses a paramount importance for T1-2N0M0 glottic laryngeal cancer. For T3-4aN0-3M0 glottic laryngeal cancer, there is an equipoise regarding the partial/total laryngectomy and non-surgical modalities for T3 glottic laryngeal cancer. Patients with extensive and/or poorly functioning T4a laryngeal cancer should not be offered organ-preserving chemoradiotherapy with salvage surgery as a back-up plan, but total laryngectomy and adjuvant (chemo) radiation. The lack of high-level evidence comparing contemporary open or transoral robotic organ-preserving surgical and non-surgical modalities does not allow any concrete conclusions in terms of oncological and functional outcome. Unnecessary tri-modality treatments should be avoided. Instead of offering one-size-fits-all approaches and over-standardized rigid institutional strategies, patient-centered informed and shared decision-making should be favored.

Abstract
Heat shock protein 47 (HSP47) is a 47 kDa collagen binding protein that has a close relationship with the development and progression of tumours. However, little is known concerning the expression profile of HSP47 in laryngeal squamous cell carcinoma (LSCC) patients and there is still insufficient data concerning the underlying mechanisms. The aim of the present study was to explore the expression of HSP47 in LSCC and provide an overview of its association with tumourigenicity and clinical prognosis. The expression of HSP47 in LSCC and adjacent non-cancerous laryngeal tissues was assessed via western blotting and immunohistochemical studies. The prognostic significance of HSP47 expression was analysed using a Kaplan-Meier survival curve. To investigate the influence of HSP47 on the viability, invasion and apoptosis of a LSCC cell line, we performed an in vitro analysis with plasmid vectors and small interfering RNA (siRNA). Our results showed that HSP47 protein expression in the LSCC tissues was markedly decreased compared to that noted in the adjacent non-cancerous tissues, and low expression of HSP47 was correlated with poor prognosis in LSCC patients. Upregulation of HSP47 via plasmid vectors inhibited the proliferation, reduced the invasive ability, increased the sensitivity to cisplatin chemotherapy, promoted apoptosis, and induced the G1 phase arrest of LSCC cells in vitro. The expression of apoptosis-regulating proteins was also altered when HSP47 was upregulated, involving increased expression of cleaved caspase-7/-8/-9, PARP, and Bax and decreased expression of Bcl-2. Our present data suggest that HSP47 is an important prognostic factor and an attractive therapeutic target in LSCC due to its influence on the biological behaviour of LSCC cells.

Abstract
BACKGROUND The optimal treatment strategy for stage I-II glottic squamous cell carcinoma (SCC) is not well-defined. This study analyzed treatment results and prognostic factors. PATIENTS AND METHODS This is a single-institution retrospective analysis of 244 patients with T1-2 glottic SCC who underwent normofractionated radiotherapy (RT) and/or surgery between 1990 and 2013. The primary endpoint was relapse-free survival (RFS). RESULTS Median age was 65 years (range: 36-92 years), the majority (82%) having stage I disease. Definitive RT was used in 82% (median dose: 68 Gy, 2 Gy per fraction). Median follow-up was 59 months. The 5‑year RFS rates were 83 and 75% (p = 0.05) for stage I and 62 and 50% (p = 0.47) for stage II in the RT and surgery groups, respectively. Multivariate analyses indicate T1 vs. T2 and RT vs. surgery as independent prognostic factors for RFS, with hazard ratios of 0.38 (95% confidence interval, CI: 0.21-0.72) and 0.53 (95% CI: 0.30-0.99), respectively (p < 0.05). The 5‑year overall and cause-specific survival rates in the whole cohort were 92 and 96%, respectively, with no significant differences between treatment groups. Anterior commissure involvement was neither a prognostic nor a predictive factor. The incidence of secondary malignancies was not significantly different between patients treated with and without RT (22 vs. 9% at 10 years, respectively, p = 0.18). CONCLUSION Despite a possible selection bias, our series demonstrates improved RFS with RT over surgery in stage I glottic SCC.

Abstract
Background Emerging evidences proposed that microRNAs are associated with regulation of distinct physio-pathological processes including development of normal stem cells and carcinogenesis. In this study we aimed to investigate microRNA profile of cancer stem-like cells (CSLCs) isolated form freshly resected larynx cancer (LCa) tissue samples. Methods CD133 positive (CD133+) stem-like cells were isolated from freshly resected LCa tumor specimens. MicroRNA profile of 12 pair of CD133+ and CD133− cells was determined using microRNA microarray and differential expressions of selvected microRNAs were validated by quantitative real time PCR (qRT-PCR). Results MicroRNA profiling of CD133+ and CD133− LCa samples with microarray revealed that miR-26b, miR-203, miR-200c, and miR-363-3p were significantly downregulated and miR-1825 was upregulated in CD133+ larynx CSLCs. qRT-PCR analysis in a total of 25 CD133+/CD133− sample pairs confirmed the altered expressions of these five microRNAs. Expressions of miR-26b, miR-200c, and miR-203 were significantly correlated with miR-363-3p, miR-203, and miR-363-3p expressions, respectively. Furthermore, in silico analysis revealed that these microRNAs target both cancer and stem-cell associated signaling pathways. Conclusions Our results showed that certain microRNAs in CD133+ cells could be used as cancer stem cell markers. Based on these results, we propose that this panel of microRNAs might carry crucial roles in LCa pathogenesis through regulating stem cell properties of tumor cells.

Abstract
OBJECTIVE Head and neck cancer is the sixth most common cancer in worldwide with an increasing incidence rate in recent years. LOXL4 is expressed in several tissues, and its expression has been shown to display a significant correlation with local lymph node metastasis. In this study, we aimed to explore the LOXL4 expression level in metastatic and non-metastatic LSCC tissues and to determine its prognostic significance. STUDY DESIGN Basic science research study. SETTING University hospital. PARTICIPANTS A total of 40 patients were included in the study. MAIN OUTCOME MEASURE LOXL4 expression status in metastatic, non-metastatic LSCC and normal tissue samples was investigated by quantitative reverse-transcription PCR. RESULTS We demonstrated that LOXL4 was significantly overexpressed in LSCC tumour tissue samples in comparison with the corresponding normal tissues (P < 0.001); however, no significant relationship has been found between LOXL4 expression and either the metastatic potential or the T classification of the specimens. CONCLUSIONS Although expression of LOXL4 is not statistically associated with neck metastases, we showed that LOXL4 expression significantly increased in laryngeal cancer.

Abstract
The cancer stem-like cells (CSLCs) are tumorigenic cells promoting initiation, progression, and spread of the tumor. Accumulating evidences suggested the presence of CSLCs in distinct tumors including laryngeal squamous cell carcinoma (LSCC). MicroRNAs have been proposed as significant regulators of carcinogenesis, and several of them have been demonstrated to have direct roles in survival of CSLCs. In this study, we aimed to explore the role of miR-145, which is downregulated in LSCC, on cancer stem cell potency of laryngeal cancer cells. We initially showed the downregulation of miR-145 expression in tumor tissue samples and in CD133-enriched CSLCs. Quantitative reverse-transcription PCR (qRT-PCR) analysis of miR-145-transfected Hep-2 cells demonstrated the inhibitory role of miR-145 on stem cell markers like SOX2, OCT4, KLF4, and ABCG2. We, then, investigated the stem cell features of miR-145-overexpressing Hep-2 cells by sphere formation assay, single-cell cloning assay, and aldehyde dehydrogenase (ALDH) assay, which all demonstrated the inhibition of stem cell potency upon miR-145 overexpression. Further qRT-PCR analysis demonstrated altered expression of epithelial to mesenchymal transition markers in miR-145-overexpressing Hep-2 cells. In conclusion, we demonstrated the regulatory role of miR-145 in stem cell characteristics of Hep-2 cells. Based on these results, we propose that miR-145 might carry crucial roles in LSCC tumorigenesis, prognosis, metastasis, chemoresistance, and recurrence through regulating stem cell properties of tumor cells.

Abstract
Background Neutrophil-lymphocyte ratio (NLR) has been shown to be associated with prognosis in various solid tumors. This study aimed to evaluate the prognostic role of NLR in patients with laryngeal squamous cell carcinoma (LSCC). Methods A total of 141 LSCC patients were retrospectively reviewed. Patients’ demographics were analyzed along with clinical and pathologic data. The optimal cutoff value of NLR was determined using receiver operating characteristic (ROC) curve analysis. The impact of the NLR and other potential prognostic factors on disease-free survival (DFS) and overall survival (OS) was assessed using the Kaplan-Meier method and multivariate Cox regression analysis. Results The optimal cutoff value of the NLR was 2.17. In the NLR ≤ 2.17 group, the 1-, 3-, and 5-year DFS rates were 88.2, 73.9 and 69.1 %, respectively, while in the NLR > 2.17 group, the DFS rates were 83.0, 54.6 and 49.2 %, respectively. Correspondingly, the 1-, 3-, and 5-year OS rates were 98.9, 85.1 and 77.4 % in the NLR ≤ 2.17 group and 97.9, 63.8 and 53.3 % in the NLR > 2.17 group, respectively. The multivariate Cox proportional hazard model analysis showed that NLR > 2.17 was a prognostic factor for both DFS [hazard ratio (HR) = 1.869; 95 % confidence interval (CI) 1.078–3.243; P = 0.026] and OS (HR =2.177; 95 % CI 1.208–3.924; P = 0.010). Conclusion Our results showed that elevated preoperative NLR was an independent predictor of poor prognosis for patients with LSCC after surgical resection.

Abstract
OBJECTIVE In order to identify a plasma microRNA (miRNA) signature of larynx cancer (LCa), we examined miRNAs profile of plasma samples obtained from 30 LCa patients (preoperative and postoperative serum samples) and 30 healthy controls. STUDY DESIGN Basic science research study. METHODS MicroRNA profiling of eight plasma samples (four from preoperative, four from control individuals) were performed using miRNA microarray. Two of the significantly deregulated miRNAs were selected for further confirmation in the remaining samples using quantitative reverse-transcription polymerase chain reaction (qRT-PCR). RESULTS Microarray profiling and qRT-PCR analysis showed that miR-221 was upregulated in LCa plasma samples. Further qRT-PCR analysis demonstrated that miR-221 was at normal levels in postoperative plasma samples. CONCLUSIONS Plasma miR-221 may have a potential as a novel diagnostic/prognostic marker and might be considered as a therapeutic target in LCa. LEVEL OF EVIDENCE N/A.

Abstract
BACKGROUND Laryngeal squamous cell carcinoma (SCC), being an aggressive malignancy, is one of the most commonly diagnosed malignant types of head and neck SCC worldwide. The recent studies suggested that αB-crystallin might play an important role in tumorigenesis. The purpose of this study was to investigate the αB-crystallin expression level in metastatic and nonmetastatic laryngeal SCC tissues and to determine its prognostic significance. METHODS Alpha-B-crystallin expression status in metastatic, nonmetastatic laryngeal SCC, and normal tissue samples was investigated by quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS We demonstrated that the expression of αB-crystallin was significantly upregulated in laryngeal SCC tumor tissue samples in comparison with the corresponding normal tissues (p < .001), although no significant association has been found between αB-crystallin expression and either the metastatic potential or the T classification of the specimens. CONCLUSION Although expression of αB-crystallin is not statistically correlated with neck metastases, we demonstrated that αB-crystallin is significantly overexpressed in laryngeal cancer.

Causes of death of patients with laryngeal cancer. Eur Arch Otorhinolaryngol 2013; 271:425-34.

Abstract
Despite remarkable advances in the care of patients with laryngeal cancer over the past several decades, including a growing awareness of therapeutic complications and attention to quality of life, little is known about the causes of mortality in this population. In addition to the laryngeal malignancy itself, acute and late or chronic treatment-associated causes, second primary cancers, intercurrent disease and psychosocial factors are all responsible for patient morbidity and mortality. We examine the current literature related to the causes of death in patients with laryngeal cancer, in the hope of guiding future interventions to improve the longevity and quality of life of individuals with this cancer.

Abstract
Treatment options for laryngeal carcinoma, one of the most common head and neck malignancies, consist of radiotherapy, surgery, chemotherapy or a combination thereof. The functional treatment of laryngeal carcinoma poses a considerable challenge because of its resistance to chemotherapy and radiotherapy, and its tendency for local recurrence. Finding ways to inhibit the energy supply of malignant tumours is becoming an increasingly attractive proposition. Glucose transporter-1 (Glut-1; encoded by the SLC2A1 gene in humans) is the main transporter of glucose in solid carcinomas and has become a focus of cancer research. Recently, it was shown that the increased expression of SLC2A1 in head and neck carcinomas is correlated with lymph node metastasis, poor survival and clinical stage, and revealed that the suppression of SLC2A1 expression by antisense oligodeoxynucleotides decreased glucose uptake and inhibited the proliferation of Hep-2 cells. Thus, the authors propose the suppression of SLC2A1 expression as a new therapeutic target for laryngeal carcinoma.
