Abstract
Head and neck squamous cell carcinoma (HNSCC) is well known as a serious health problem worldwide, especially in low-income countries or those with limited resources, such as most countries in Latin America. International guidelines cannot always be applied to a population from a large region with specific conditions. This study established a Latin American guideline for care of patients with head and neck cancer and presented evidence of HNSCC management considering availability and oncologic benefit. A panel composed of 41 head and neck cancer experts systematically worked according to a modified Delphi process on (1) document compilation of evidence-based answers to different questions contextualized by resource availability and oncologic benefit regarding Latin America (region of limited resources and/or without access to all necessary health care system infrastructure), (2) revision of the answers and the classification of levels of evidence and degrees of recommendations of all recommendations, (3) validation of the consensus through two rounds of online surveys, and (4) manuscript composition. The consensus consists of 12 sections: Head and neck cancer staging, Histopathologic evaluation of head and neck cancer, Head and neck surgery-oral cavity, Clinical oncology-oral cavity, Head and neck surgery-oropharynx, Clinical oncology-oropharynx, Head and neck surgery-larynx, Head and neck surgery-larynx/hypopharynx, Clinical oncology-larynx/hypopharynx, Clinical oncology-recurrent and metastatic head and neck cancer, Head and neck surgery-reconstruction and rehabilitation, and Radiation therapy. The present consensus established 48 recommendations on HNSCC patient care considering the availability of resources and focusing on oncologic benefit. These recommendations could also be used to formulate strategies in other regions like Latin America countries.

Abstract
Objective United States oncology trends consistently demonstrate that nearly half of T4a larynx carcinoma patients are treated with larynx preservation, despite national guidelines favoring laryngectomy. This study identifies clinical decision-making drivers and defines patient subsets that should become targets for care improvement. Methods Retrospective analysis of patients with cT4 squamous cell carcinoma of the larynx from US National Cancer Database 2005-2016. Demographic data and survival rates between clinical pathways were compared. Survival was estimated by Kaplan-Meier method with statistical comparisons assessed by log-rank test. Results Of 11,556 patients with cT4 disease, laryngectomy (TL) was the initial treatment for 4627 (40%) patients. Larynx preservation via chemoradiation (CRT) occurred for 4307 patients. TL and CRT patients had similar Charlson-Deyo comorbidity indices and insurance status. TL patients had higher total tumor size, lower N3 rates and were more often seen at academic institutions (p < .0001). N0 surgery patients with adjuvant treatment demonstrated superior median survival (MS) compared to CRT (surgery + radiation MS: 69 months, surgery + chemoradiation MS: 66, CRT MS: 37.7), p < .0001. MS for N1/N2 disease patients was 56.5 months for surgery + radiation and 35.5 months for surgery + CRT, superior to CRT, MS 30.8 months, p < .0001. Tri-modality N3 patients with up front surgery had similar MS compared to CRT (surgery + chemoradiation 21.3 months vs. CRT 16.1), p = .95. Conclusion National quality improvement initiatives are needed to promote guideline adherence and improve survival in advanced larynx cancer. Targets for such initiatives should be patients with limited or no nodal disease burden, that meet clear T4a imaging criteria. Level of Evidence Level IV, non-randomized controlled cohort.

Abstract
Background Cytoplasmic activation/proliferation-associated protein-1 (CAPRIN1) plays an important role in carcinogenesis, whereas its role in laryngeal squamous cell carcinoma remains unclear. This study was designed to investigate the roles of CAPRIN1 in glycolysis and chemoresistance and its underlying mechanisms in laryngeal squamous cell carcinoma. Methods Cell viability was evaluated by using CCK-8 and colony formation assays. qRT-PCR, Western blotting, and immunohistochemistry were used to determine the expressions of target genes. Gene knockdown and overexpression cell lines were constructed by performing transfection of siRNAs and plasmids, respectively. Luciferase reporter assay, RNA pull-down, and RNA immunoprecipitation assays were applied to evaluate the RNA-protein interactions. The Kaplan-Meier analysis was performed to evaluate the relationship between gene expression and overall survival rate. Results An elevation of CAPRIN1 was identified to be associated with chemoresistance and poor prognosis in patients with laryngeal cancer. The increase of CAPRIN1 promoted glycolysis and chemoresistance, whereas the knockdown of CAPRIN1 inhibited glycolysis and chemoresistance in laryngeal cancer cells. The underlying mechanistic investigation revealed that CAPRIN1 promoted glycolysis and chemoresistance of laryngeal cancer cells by the regulation of Zic Family Member 5 (ZIC5). Conclusion CAPRIN1 promoted laryngeal squamous cell carcinoma glycolysis and chemoresistance by the regulation of ZIC5.

Recent insights in the PI3K/Akt pathway as a promising therapeutic target in combination with EGFR-targeting agents to treat head and neck squamous cell carcinoma. Med Res Rev 2021; 42:112-155. [PMID: 33928670 DOI: 10.1002/med.21806] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 02/17/2021] [Accepted: 03/31/2021] [Indexed: 12/20/2022]
Abstract
Resistance to therapies targeting the epidermal growth factor receptor (EGFR), such as cetuximab, remains a major roadblock in the search for effective therapeutic strategies in head and neck squamous cell carcinoma (HNSCC). Due to its close interaction with the EGFR pathway, redundant or compensatory activation of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway has been proposed as a major driver of resistance to EGFR inhibitors. Understanding the role of each of the main proteins involved in this pathway is utterly important to develop rational combination strategies able to circumvent resistance. Therefore, the current work reviewed the role of PI3K/Akt pathway proteins, including Ras, PI3K, tumor suppressor phosphatase and tensing homolog, Akt and mammalian target of rapamycin in resistance to anti-EGFR treatment in HNSCC. In addition, we summarize PI3K/Akt pathway inhibitors that are currently under (pre)clinical investigation with focus on overcoming resistance to EGFR inhibitors. In conclusion, genomic alterations in and/or overexpression of one or more of these proteins are common in both human papillomavirus (HPV)-positive and HPV-negative HNSCC tumors. Therefore, downstream effectors of the PI3K/Akt pathway serve as promising drug targets in the search for novel therapeutic strategies that are able to overcome resistance to anti-EGFR treatment. Co-targeting EGFR and the PI3K/Akt pathway can lead to synergistic drug interactions, possibly restoring sensitivity to EGFR inhibitors and hereby improving clinical efficacy. Better understanding of the predictive value of PI3K/Akt pathway alterations is needed to allow the identification of patient populations that might benefit most from these combination strategies.

Medicine (Baltimore) 2020; 99:e23004.

Abstract
The option of T1a glottic cancer treatments remarkably varied in different countries. This study aimed to construct predictive models to predict overall survival (OS) and cancer-specific survival (CSS) of patients with initially diagnosed T1a glottic cancer. And we used propensity score matching (PSM) to reassess the effect of treatments.Data of patients with initially diagnosed T1a glottic cancer were extracted from the Surveillance, Epidemiology, and End Results database. Patients with complete information were randomly divided into the training and the validation cohorts (7:3). Cox regression was conducted to screen significant predictors of the OS and the CSS. PSM was performed to mimic randomized controlled trials. Survival analyses were performed by Kaplan-Meier survival methods, and log-rank tests were utilized.A total of 2342 patients met the inclusion criteria. Survival analyses showed that patients who underwent primary site surgery would have better OS and CSS. Univariate analyses and multivariate analyses proved that stage, N stage, primary site surgery, and chemotherapy significantly affected both the OS and the CSS. Predictive nomograms were established to predict patients' prognosis. Finally, the OS and the CSS for patients who underwent primary site surgery alone were significantly longer than those who underwent radiation alone before and after PSM.We constructed nomograms predicting the OS and the CSS of patients with initially diagnosed T1a glottic cancer. Compared to our previous studies, this study indicated that primary site surgery may be superior to radiation and chemotherapy. At present, chemotherapy should be not recommended for T1a glottic cancer patients.

Abstract
BACKGROUND In head and neck cancer, docetaxel, cisplatin and 5-fluorouracil (TPF) is often given in two or three cycles. The purpose of this study was to perform single-cycle TPF for chemoselection in patients with advanced hypopharyngeal laryngeal cancer. PATIENTS AND METHODS The study included 56 patients with stage III/IV advanced hypopharyngeal/laryngeal squamous cell carcinoma. The primary endpoint was progression-free survival (PFS), and secondary endpoints were overall survival (OS), TPF response rate, laryngeal sparing, and grade 3 or more adverse events. RESULTS The median PFS was 34.8 months. The median OS was not evaluable. The response rate was 71%. The median laryngeal preservation period was not estimable. Grade 3 or 4 adverse events were reported in 46 patients. CONCLUSION PFS rate in this study may have been improved by selecting surgical treatment for patients for whom chemoradiotherapy seemed less effective. One cycle of TPF in induction chemotherapy appeared effective for chemoselection.

Abstract
Laryngeal carcinoma (LCC) is a common malignant tumor with low radiosensitivity and generally poor response rates. The ubiquitin protein ligase E3 component n-recognin 5 (UBR5) has prognostic implications in several neoplasms; however, its role in LCC and radiotherapy sensitivity remains unknown. Immunohistochemistry and bioinformatics analyses were performed to measure UBR5 protein and mRNA expression in LCC and adjacent non-tumor tissues. The gene and protein expression of UBR5 in LCC and HuLa-PC cell lines were measured using quantitative PCR and western blot analyses. Following transfection with small interfering RNA or UBR5 overexpression plasmid in LCC cells, the proliferation, cell cycle distribution, invasion, migration and radiosensitivity of LCC cells were analyzed. UBR5-related lncRNA, targeted miRNA and protein-protein interaction networks were analyzed using bioinformatics. Finally, the expression of the p38/mitogen-activated protein kinase (MAPK) pathway was evaluated following UBR5 silencing in M2E cells treated with radiation. Increased UBR5 expression was observed in LCC tissues compared with adjacent non-tumor tissues, and it was correlated with poor overall survival of LCC patients. After overexpression or silencing of UBR5 in M2E and M4E LCC cells, cell proliferation and radiosensitivity were significantly increased or decreased, respectively, compared with the control groups. The percentage of S phase cells decreased in the UBR5 si-RNA group compared with that in the control group, while overexpression of UBR5 exerted no effect on the cell cycle. In addition, the expression of Bcl-2 and p38 was decreased in the si-UBR5 combined with radiation groups. The level of phosphorylated p38 expression was increased after combination of si-UBR5 with radiation. The small molecule inhibitor of p38/MAPK signaling, SB203580, decreased the viability of UBR5-overexpressing cells and the survival fraction when cells were exposed to radiation. These findings demonstrated that UBR5 may be involved in regulating cell proliferation and sensitivity to radiotherapy in LCC via the p38/MAPK pathway, thereby highlighting its possible value for the development of new therapeutic strategies and targets for the treatment of this disease.

Silencing of miR-17-5p suppresses cell proliferation and promotes cell apoptosis by directly targeting PIK3R1 in laryngeal squamous cell carcinoma. Cancer Cell Int 2020; 20:14. [PMID: 31938022 PMCID: PMC6954602 DOI: 10.1186/s12935-020-1096-3] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Accepted: 01/02/2020] [Indexed: 02/07/2023] Open
Abstract
Background Increasing evidence has suggested that microRNAs (miRNAs) act as key post-transcriptional regulators in tumor progression. Previous studies have confirmed that miR-17-5p functions as an oncogene in multiple cancers and contributes to tumor progression. However, the role and biological functions of miR-17-5p in the development of laryngeal squamous cell carcinoma (LSCC) still remain unknown. Methods qRT-PCR was used to detect miRNA and mRNA expression levels in LSCC tissues and cell lines. CCK-8 assay was used to measure cell viability and flow cytometry was performed to evaluate cell apoptosis. Western blot analysis was used to detect the protein levels of BAX, BCL-2, cleaved Caspase-3, PIK3R1 and AKT. Luciferase reporter assay was used to detect the effect of miR-17-5p on PIK3R1 expression. Xenograft animal model was used to test the effect of miR-17-5p on LSCC cell in vivo. Results In the present study, we found that miR-17-5p expression level was upregulated in LSCC tissues and cell lines. Depletion of miR-17-5p in LSCC cells significantly reduced cell proliferation and promoted cell apoptosis in vitro and in vivo. Mechanically, knockdown of miR-17-5p in LSCC cells inhibited BCL-2 expression while enhanced BAX and cleaved Caspase-3 protein expression. Moreover, depletion of miR-17-5p in LSCC cells suppressed AKT phosphorylation but did not influence PTEN expression. Importantly, miR-17-5p positively regulated PIK3R1 expression by directly binding to its 3′-untranslated region (UTR). Additionally, PIK3R1, which expression was downregulated in LSCC tissues and cell lines, was involved in LSCC cell survival by modulating the activation of AKT signal pathway. Dysregulation of miR-17-5p/PIK3R1 axis was participated in LSCC cell proliferation and apoptosis by inhibiting the activation of the PI3K/AKT signaling pathway. Conclusions In conclusion, our study indicates that the miR-17-5p/PIK3R1 axis plays an essential role in the development of LSCC and provides a potential therapeutic target for LSCC treatment.

Abstract
Population-based studies indicate that chemoradiation has become the most popular treatment for advanced laryngeal cancers; however, by extrapolating trial results to the general population, several issues have emerged, such as reduced overall survival, non-functional laryngeal preservation, and poor response to treatment. Although included in these trials, T4 laryngeal and hypopharyngeal cancers with cartilage invasion formed a small percentage of these patients and questions over whether they were appropriately staged remain unanswered. Literature on the use of chemoradiation in this set of patients, including the challenges, treatment considerations, and factors predicting response to treatment and outcomes, was reviewed. Current evidence indicates that all patients of T4 laryngeal and hypopharyngeal cancer are not suitable candidates for organ preservation; this modality should be offered only to select patients with good performance status and access to rehabilitative care and regular follow-up in order to achieve good results.

Abstract
Introduction: Subsequent to the 2006 FDA approval of cetuximab, a variety of molecular targeting agents have been evaluated in head and neck squamous cell carcinoma (HNSCC). The treatment outcomes of recurrent and/or metastatic (R/M) HNSCC, in particular, remain dismal. The 2016 FDA approval of PD-1 immune checkpoint inhibitors has expanded the treatment options for R/M HNSCC and highlights the potential for immune-based therapies. Areas covered: We will review the clinical application of EGFR-targeted agents, alone and in combination with other drugs. Molecular targeting agents directed against the IL6/PI3K/STAT3 signaling pathway will be covered. In addition, evaluation of immune checkpoint inhibitors in HNSCC, along with ongoing combination trials incorporating these agents, will be discussed. The expanded indications of emerging drugs and the potential clinical benefit of new drugs and treatment combinations will be summarized. Expert opinion: In recent years, there has been a major shift toward immunotherapy-based approaches for the treatment of HNSCC, leading to significant improvements in outcomes for a subset of patients. Leveraging the increased understanding of the genetic alterations that characterize individual HNSCC tumors will facilitate precision medicine approaches using targeted agents, immunotherapies, as well as standard chemotherapy and radiation.

Radiotherapy for locally advanced resectable T3-T4 laryngeal cancer-does laryngeal preservation strategy compromise survival? JOURNAL OF RADIATION RESEARCH 2018; 59:77-90. [PMID: 29190391 PMCID: PMC5778501 DOI: 10.1093/jrr/rrx063] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/02/2017] [Revised: 08/14/2017] [Indexed: 06/07/2023]
Abstract
With the advancement of chemotherapy, a laryngeal preservation (LP) strategy was explored with the aim of improving maintenance of quality of life. Induction chemotherapy (ICT) following radiotherapy (RT) was considered a viable option because of its high initial response rate without hampering of overall survival (OS). Subsequently, concurrent chemoradiotherapy (CCRT) using CDDP became the standard of care for LP, showing the best LP ratio. For enhancing treatment intensity, ICT with taxan + CDDP + 5-FU (TPF-ICT) followed by RT showed superiority over ICT with CDDP + 5-FU (PF-ICT) followed by RT. Given that almost all randomized controlled trials investigating ICT include not only operable (endpoint, LP) but also inoperable (endpoint, OS) cases, physicians are faced with a dilemma regarding application in daily practice. In addition, increased treatment intensity causes augmentation of adverse events, which might reduce compliance. Thereafter, cetuximab, an effective drug with fewer adverse effects [bioradiotherapy (BRT)], emerged as another option. However, little evidence has confirmed its superiority over RT (or CCRT) in laryngeal cancer subpopulations. In spite of these developments, the OS of patients with laryngeal cancer has not improved for several decades. In fact, several studies indicated a decrease in OS during the 1990s, probably due to overuse of CCRT. Fortunately, the latter was not the case in most institutions. Currently, no other treatment has better OS than surgery. The eligibility criteria for LP and/or surgery largely depend upon the available expertise and experience, which differ from one institution to another. Therefore, a multidisciplinary team is required for the treatment of LP.

Abstract
Objective To evaluate the radiosensitivity effect of CpG oligodeoxyribonucleotide (ODN)
7909 on human epidermoid cancer strain-2 (Hep-2) cells in
vitro and discuss the potential for improved radiotherapy
treatment in patients with laryngeal squamous cell carcinoma. Methods Toll-like receptor (TLR) 9 expression was assessed in Hep-2
cells using Western blots and reverse transcription polymerase chain
reaction. Cell Counting Kit-8 was used to detect Hep-2 cell viability at 24
and 48 h following treatment with different CpG ODN7909 concentrations.
Cellular colonization was evaluated using microscopy. Cell cycle
distribution and apoptosis rate was determined with flow cytometry.
Interleukin (IL)-12 and tumour necrosis factor (TNF)-α concentrations were
detected by enzyme-linked immunosorbent assay. Results Hep-2 cells were found to express TLR9, and CpG ODN7909
treatment suppressed Hep-2 cell viability in a dose- and time-dependent
manner. Cell survival curve analyses revealed a sensitivity enhancement
ratio of the mean death dose of 1.225 for CpG ODN7909 plus irradiation
versus irradiation alone. Furthermore, the population of Gap 2/mitotic-phase
cells, apoptosis rate and secreted IL-12 and TNF-α levels were significantly
increased in Hep-2 cells treated with CpG ODN7909 plus irradiation versus IR
alone. Conclusion CpG ODN7909 enhanced the radiosensitivity of Hep-2 cells in
vitro.

Abstract
For early-stage head and neck cancer (HNC), surgery (S) or radiotherapy (RT) is a standard treatment. The multidisciplinary approach, which includes multimodality treatment with S followed by RT, with or without chemotherapy (CT) or concurrent chemoradiotherapy (CRT), is required for locally advanced head and neck cancer (LAHNC). CRT improves prognosis, locoregional control (LRC), and organ function in LAHNC, compared to RT alone. Prognosis in recurrent/metastatic HNC (R/M HNC) is dismal. Platinum-based CT, combined with the anti-Epidermal Growth Factor Receptor (EGFR) antibody (Ab) cetuximab, is used in first-line setting, while no further validated options are available at progression. The complexity of disease is, in part, due to the heterogeneity of organs and functions involved and the need for a multimodality approach. In addition, the patient population (often elderly and/or patients with smoking and alcohol habits) argues for an individually tailored treatment plan. Furthermore, treatment goals - which include cure, organ, and function preservation, quality of life and palliation - must also be considered. Thus, optimal management of patients with HNC should involve a range of healthcare professionals with relevant expertise. The purpose of the present review is to 1) highlight the importance and necessity of the multidisciplinary approach in the treatment of HNC; 2) update the knowledge regarding modern surgical techniques, new medical and RT treatment approaches, and their combination; 3) identify the treatment scenario for LAHNC and R/M HNC; and 4) discuss the current role of immunotherapy in HNC.

Single-cycle induction chemotherapy for resectable advanced hypopharyngeal cancer. Int J Clin Oncol 2017; 22:442-447. [PMID: 28062933 DOI: 10.1007/s10147-016-1084-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Accepted: 12/26/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND The role of induction chemotherapy (IC) in the treatment of resectable advanced head and neck squamous cell carcinoma has not been elucidated, and the most effective IC regimen for chemoselection is still unknown. At our institute we have not used the triple combination of docetaxel, cisplatin, fluorouracil (TPF) for chemoselection, but rather the double combination of docetaxel + cisplatin (TP). The aim of this study is to report the outcome of patients with advanced hypopharyngeal cancer treated by single cycle of IC with TP followed by chemoradiation (CRT) or surgery. METHODS A total of 29 patients with resectable advanced hypopharyngeal cancer who were treated with a single cycle of IC were entered into the study. Responders were treated by CRT while nonresponders underwent surgery. Outcomes were analyzed using the Kaplan-Meier method. RESULTS A single cycle of IC with TP achieved response in 21 of the 29 patients. The major side effect was neutropenia which could be managed without delaying the sequential treatment. The 2-year overall survival and disease-specific survival were both 74.0% (stage III 100%, stage IVA 69.1%). The cumulative 2-year laryngeal preservation rate was 100% for stage III and 53.6% for stage IVA. CONCLUSION A single cycle of IC with the combination of docetaxel + cisplatin may be sufficient to select advanced hypopharyngeal cancer patients with radio-sensitivity. IC intended for organ preservation strategies should be low toxic. Our strategy may be a useful for providing the benefits of IC and the opportunity for curative surgery without delay.
