Ghosh A, Moorthy A. Prevalence and effect of PIK3CA H1047R somatic mutation among Indian head and neck cancer patients. Saudi J Biol Sci 2024; 31:104029. [PMID: 38873617 PMCID: PMC11170471 DOI: 10.1016/j.sjbs.2024.104029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 05/17/2024] [Accepted: 05/25/2024] [Indexed: 06/15/2024] Open
Abstract
PIK3CA is one among the several mutated genes in cancer, including head and neck squamous cell carcinoma (HNSCC). H1047R is a hotspot somatic mutation in PIK3CA that occurs most frequently in several forms of cancers. Distribution of PIK3CA H1047R mutation in Indian HNSCC patients was screened and its effect on disease progression and response to treatment was analysed in this study. Genomic DNA was extracted from tumour biopsies of HNSCC patients (n = 48) and polymerase chain reaction coupled restriction fragment length polymorphism (PCR-RFLP) technique was used to screen for the mutation. Overall survival (OS) and Progression-free survival (PFS) of the patients were calculated in order to study effect of this mutation on survival and response to treatment respectively. Results showed that irrespective of patients' criteria, twenty-five patients (52 %) carried a heterozygous form of mutation (His/Arg) and the rest (48 %) were wild type (His/His). The mean OS of the cohort with the mutation was 20.451 months (SE ± 1.710 months) while 26.31 months (SE ± 2.431) was in wild type population. PFS of the patients with the mutation was 18.612 months (SE ± 2.072), and for the wild type population, it was 26.31 months (SE ± 2.431). These observations suggest that Indian HNSCC patients with PIK3CA H1047R mutation have poor prognosis.

JCO Glob Oncol 2024; 10:e2300464. [PMID: 38513185 PMCID: PMC10965205 DOI: 10.1200/go.23.00464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/12/2024] [Accepted: 01/24/2024] [Indexed: 03/23/2024] Open
Abstract
PURPOSE Head and neck cancer accounts for about one third of the global burden in India. Mucosal high-risk human papillomavirus (HPV) has been hypothesized as a contributory risk factor for head and neck cancer (HNC) but its prevalence in Indian patients is not well established. Therefore, this systematic review and meta-analysis aimed to estimate the prevalence of HPV in HNC in India and their attributable fraction by considering the biomarkers of carcinogenesis, p16, and HPV E6/E7 mRNA. METHODS A systematic literature search was done in Medline via PubMed, Embase, Scopus, ScienceDirect, ProQuest, and Cochrane to identify studies on HPV and HNC in the Indian population, published between January 1990 and October 2022. Fifty-four eligible studies were identified and relevant clinical information was collected. Meta-analysis was conducted to estimate the pooled prevalence of HPV DNA, p16INK4a, and E6/E7 mRNA percent positivity by random-effect logistic regression model using Metapreg, STATA 18. RESULTS Thirty-four high-quality studies were taken for meta-analysis. The pooled prevalence of HPV in HNC was 20% (95% CI, 12 to 32) with a high level of heterogeneity (I2 = 90.79%). The proportion of HPV in oropharyngeal cancer (OPC; 22% [95% CI, 13 to 34]) and laryngeal cancer (LC; 29% [95% CI, 17 to 46]) was higher than in oral cancer (OC; 16% [95% CI, 8 to 30]). The HPV-attributable fraction of OPC, considering the E6/E7 mRNA and p16 positivity, was 12.54% and 9.68%, respectively, almost similar to LC (11.6% and 9.57%), while it was much lower in OC (3.36% and 4%). CONCLUSION The HPV-attributable fraction is considerably lower for OC, suggesting a negligible causative role of HPV in OC. A significant proportion of OPC and LC are attributed to HPV; however, their exact causative role is unclear because of the presence of other known risk factors.

Abstract
BACKGROUND Oral cancer is one of the most common types of cancer worldwide, and India shows a high incidence of oral squamous cell carcinoma (OSCC) cases. Kerala accounts for a sizeable number of these cases, most of which can be attributed to the deleterious habits prevalent in a vast majority of the population. A comprehensive descriptive-prospective study was done in our institution over 18 months to identify the possible risk factors, to describe the clinical and sociodemographic variables of OSCC, and to understand the burden of this dreaded disease in the North Kerala population. MATERIALS AND METHODS Data collection was done using a structured pro forma. The data were tabulated and organized; uni- and bivariate analysis were performed along with cross-tabulations for various parameters and relevant variables. A total of 243 histopathologically confirmed cases of OSCC during 18 months comprised the sample in this study. RESULTS Among the 243 cases, 220 patients had deleterious habits. Betel chewing was the most predominant habit. Buccal mucosa was the commonly affected site. Twenty-three patients had no history of any habits. Majority of the patients presented in stage 3 and 4 of the disease. Moderately differentiated squamous cell carcinoma was the major histologic type. CONCLUSION The majority of the patients had clinical lesions corresponding to the habit usage, showing a low awareness of tobacco cessation and intervention programs and a high burden of OSCC in the North Kerala population.

Abstract
Global trends in human papillomavirus (HPV)-associated head and neck cancers (HNC), specifically in the oropharynx subsite, have been dynamically changing, leading to new staging and treatment paradigms. Epidemiologic studies have noted regional variations in HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). While HPV vaccination remains the main preventative approach, vaccination policy in relation to gender neutrality is heterogeneous and particularly sparse in low- and middle-income countries, where the burden of global cancer cases and HPV-associated HNC are not well-characterized in certain regions. This review summarizes the existing literature on regional variations of HPV-associated OPSCC and gender-neutral vaccine policies. Based on available data, the incidence of HPV-associated OPSCC is highest in North America, Europe, and Oceania. As of 2022, 122 of 195 (63%) World Health Organization (WHO) member states had incorporated HPV vaccinations nationally; of these, 41 of 122 (34%) member states have introduced gender-neutral vaccine coverage. Future research is needed to describe continued evolving trends in HPV-associated OPSCC, understand underlying risk factors leading to regional variation in disease, and implement gender-neutral policy more broadly.

Abstract
BACKGROUND The literature on modern-era outcomes of oropharyngeal squamous carcinoma (OPSCC) in India is limited. MATERIALS AND METHODS We analyzed records of consecutive patients with OPSCC treated using a curative SIB IMRT regimen of 66 Gy/30#/6 weeks. RESULTS One hundred fifteen patients from July 2011 to December 2018 were analyzed. Twenty of 69 patients tested positive for p16. In p16 positive patients, the K-M probability of being disease free and alive at 2 years, with at least one follow-up 3 months after treatment, was 83% (median not reached) compared with 48% if p16 was unknown/negative. Patients staged as IVB p16 negative had a 2-year DFS of 25%. Patients unfit for cisplatin and consequently received other agents had 2-year DFS estimated at 20%. CONCLUSIONS Intensity-modulated radiation therapy (IMRT) with simultaneous integrated boost (SIB) and concurrent chemotherapy was feasible, with toxicity and disease control comparable to available literature. AJCC Stage IVB p16 negative disease had notably poor outcome.

Abstract
It has been over four decades since the launch of the National Cancer Control Programme in India, yet the cancer screening rates for oral cancer remain unremarkable. Moreover, India is bracing a large burden of oral cancer with poor survival rates. An effective public health programme implementation relies on a multitude of factors related to cost-effective evidence-based interventions, the healthcare delivery system, public health human resource management, community behaviour, partnership with stakeholders, identifying opportunities and political commitment. In this context, we discuss the various challenges in the early detection of oral premalignant and malignant lesions and potential solutions.

Abstract
To find if an association could be established between Human Papilloma Virus (HPV) infection and oropharyngeal cancers (OPCs) in a group of patients known to be regular users of tobacco, and to determine the impact of HPV status on clinical outcomes.Case records of 212 patients with AJCC-7 (The American Joint Committee on Cancer 7th edition) stages II-IVB non metastatic squamous cell carcinoma of the oropharynx treated using radical radiotherapy with or without chemotherapy during the years 2015-2018 were retrieved. Formalin-fixed, paraffin-embedded blocks from oropharyngeal biopsies were available for 177 patients and were evaluated for p16 expression by immunohistochemical (IHC) staining. More than 50% nuclear staining with or without cytoplasmic staining was considered HPV+ . The association between tobacco use and HPV, as well as the influence of HPV status on survival outcomes were assessed. p16 expression was found to be positive in 23(13%) patients. Significant association was found between chewable tobacco usage and HPV positivity (p = 0.051). The median follow up was 20.5 months (range: 3-80). 5-year Overall Survival was 43.4% and 29.8% (p = 0.044) in HPV+ and HPV- patients, respectively. Local control was significantly better in HPV+ patients (38.6% vs. 25.3%, p = 0.049). There was also a trend towards improved Disease-free Survival in HPV+ patients (31 months vs. 15 months, p = 0.078). Though less in prevalence among the Indian population, improved outcomes in HPV+ OPC patients and widely available IHC HPV assays signifies the routine implementation of p16 testing in day-to-day clinical practice.

Framework for Machine Learning of CT and PET Radiomics to Predict Local Failure after Radiotherapy in Locally Advanced Head and Neck Cancers. J Med Phys 2021; 46:181-188. [PMID: 34703102 PMCID: PMC8491314 DOI: 10.4103/jmp.jmp_6_21] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 06/07/2021] [Accepted: 06/07/2021] [Indexed: 01/06/2023] Open
Abstract
Context: Cancer Radiomics is an emerging field in medical imaging and refers to the process of converting routine radiological images that are typically qualitatively interpreted to quantifiable descriptions of the tumor phenotypes and when combined with statistical analytics can improve the accuracy of clinical outcome prediction models. However, to understand the radiomic features and their correlation to molecular changes in the tumor, first, there is a need for the development of robust image analysis methods, software tools and statistical prediction models which is often limited in low- and middle-income countries (LMIC). Aims: The aim is to build a framework for machine learning of radiomic features of planning computed tomography (CT) and positron emission tomography (PET) using open source radiomics and data analytics platforms to make it widely accessible to clinical groups. The framework is tested in a small cohort to predict local disease failure following radiation treatment for head-and-neck cancer (HNC). The predictors were also compared with the existing Aerts HNC radiomics signature. Settings and Design: Retrospective analysis of patients with locally advanced HNC between 2017 and 2018 and 31 patients with both pre- and post-radiation CT and evaluation PET were selected. Subjects and Methods: Tumor volumes were delineated on baseline PET using the semi-automatic adaptive-threshold algorithm and propagated to CT; PyRadiomics features (total of 110 under shape/intensity/texture classes) were extracted. Two feature-selection methods were tested for model stability. Models were built based on least absolute shrinkage and selection operator-logistic and Ridge regression of the top pretreatment radiomic features and compared to Aerts' HNC-signature. Average model performance across all internal validation test folds was summarized by the area under the receiver operator curve (ROC). Results: Both feature selection methods selected CT features MCC (GLCM), SumEntropy (GLCM) and Sphericity (Shape) that could predict the binary failure status in the cross-validated group and achieved an AUC >0.7. However, models using Aerts' signature features (Energy, Compactness, GLRLM-GrayLevelNonUniformity and GrayLevelNonUniformity-HLH wavelet) could not achieve a clear separation between outcomes (AUC = 0.51–0.54). Conclusions: Radiomics pipeline included open-source workflows which makes it adoptable in LMIC countries. Additional independent validation of data is crucial for the implementation of radiomic models for clinical risk stratification.

Abstract
Purpose To investigate the impact of genetic variants of DNA repair and pro-fibrotic pathway genes on the severity of radiation-induced subcutaneous fibrosis in patients of oropharyngeal carcinoma treated with radical radiotherapy. Materials and Methods Patients of newly diagnosed squamous cell carcinoma of oropharynx being treated with two-dimensional radical radiotherapy were enrolled in the study. Patients who had undergone surgery or were receiving concurrent chemotherapy were excluded. Patients were followed up at 6 weeks post completion of radiotherapy and every 3 months thereafter for a median of 16 months. Subcutaneous fibrosis was graded according to the Radiation Therapy Oncology Group (RTOG) and the European Organization for Research and Treatment of Cancer (EORTC) grading system and the maximum grade was recorded over the length of the patient’s follow-up. Patients with severe fibrosis (≥G3), were compared to patients with minor (≤G2) fibrotic reactions. Eight single nucleotide polymorphisms of 7 DNA repair genes and 2 polymorphisms of a single pro-fibrotic pathway gene were analyzed by Polymerase Chain Reaction and Restriction Fragment Length Polymorphism and were correlated with the severity of subcutaneous fibrosis. Results 179 patients were included in the analysis. Subcutaneous fibrosis was seen in 168 (93.9%) patients. 36 (20.1%) patients had severe (grade 3) fibrosis. On multivariate logistic regression analysis, Homozygous CC genotype of XRCC3 (722C>T, rs861539) (p=0.013*, OR 2.350, 95% CI 1.089-5.382), Homozygous AA genotype of ERCC4 Ex8 (1244G>A, rs1800067) (p=0.001**, OR 11.626, 95% CI 2.490-275.901) and Homozygous TT genotype of XRCC5 (1401G>T, rs828907) (p=0.020*, OR 2.188, 95% CI 1.652-7.334) were found to be predictive of severe subcutaneous fibrosis. On haplotype analysis, the cumulative risk of developing severe fibrosis was observed in patients carrying both haplotypes of variant Homozygous AA genotype of ERCC4 Ex8 (1244G>A, rs1800067) and Homozygous TT genotype of XRCC5 (1401 G>T, rs828907) (p=0.010*, OR 26.340, 95% CI 4.014-76.568). Conclusion We demonstrated significant associations between single nucleotide polymorphisms of DNA repair genes and radiation-induced subcutaneous fibrosis in patients of oropharyngeal carcinoma treated with radiotherapy. We propose to incorporate these genetic markers into predictive models for identifying patients genetically predisposed to the development of radiation-induced fibrosis, thus guiding personalized treatment protocols.

OBJECTIVE To assess the oncological outcome and prognostic factors for primary Oral Squamous Cell Cancer (OSCC) staged as per AJCC 8th pTNM, and treated by the contemporary standard of primary surgery and pathology directed adjuvant radiation-chemoradiation. METHODS A single institution cohort from a tertiary care academic institution in North India. Case inclusion 2013 to 2016; n = 218, median follow-up 35 months. All patients were restaged as per the AJCC 8th pTNM classification. Analysis for Overall Survival (OS), Disease-free Survival(DFS), and factors impacting outcome (Cox proportionate model Multivariate analysis). RESULTS AJCC pTNM 7th to 8th edition conversion led to upstaging in 16.5%. Stage-II demonstrated greatest stage migration and apparent improvement in OS and DFS (P < .09). Discordance was noted between the presurgical (clinico-radiologic) and postsurgical (pathological) nodal status in 40.3% (88/218; 54 pathologically upstaged;34 downstaged). Pathological downstaging was particularly significant with advanced stage Gingivo-Buccal Cancers (25/73-34.7%). Stage-I-II early cancers had 3 years. OS-86.7% and DFS-78.8%; Stage-III-IV advanced cancers had 3 years. OS-56.7% and DFS-46.6%. Multivariate analysis identified poorer OS and DFS for age < 40 years (HR-1.8; 2.0), skin involvement (HR-2.1; 2.6) and pN+ status (HR-2.4; 3.5). Bone involvement did not compromise survival in this surgically treated set of patients. CONCLUSION Age < 45 is newly identified as significantly compromising DFS and OS in Oral Cancer. Established factors of skin involvement and pN+ are confirmed as impacting DFS-OS. An apparent improvement in survival in Stage II Cancers is noted as consequent to adoption of AJCC 8th edition staging.

Abstract
INTRODUCTION Inclusion of depth of invasion (DOI) and a separate classification for human papillomavirus (HPV)-associated Oropharyngeal Cancers (OPCs) are two of the many major changes in the 8th edition of the American Joint Committee on Cancer staging system. After more than 2 years of implementation, the authors found the need to evaluate if the Indian clinicians found it feasible to apply the system in their practice and if the same has influenced their decision-making. METHODS The survey was done in the form of a questionnaire which was distributed personally and via the internet to 100 clinicians. Seventy-two clinicians responded to the questionnaire. The results were analyzed and frequency distribution was computed. RESULTS Eighty-three percent of the clinicians experienced that palpation of the tumour was not a reliable method to determine the DOI. The common issues stated by the clinicians were difficulty in assessing DOI in certain subsites of the oral cavity (most commonly retromolar trigone-83%), inability to determine DOI in patients with trismus, and inability to correlate pathological and clinical DOI. Thirteen percent of the clinicians did not rely on radiological tools for measuring the DOI. Seventy percent of the clinicians did not perform a P16 assay for patients with oropharyngeal cancers. Fifty percent of the clinicians preferred chemoradiotherapy for early HPV positive oropharyngeal cancers. DISCUSSION Based on the results of the survey, the authors recommend a need for more interpretative guidelines and methods for determining the DOI. The authors also emphasize the need for determining HPV status for all oropharyngeal carcinomas.

Abstract
OBJECTIVE Tobacco consumption is one of the major etiological factors for oral cancer, but it also develops in non-tobacco users, with unknown etiologies. Cellular models for tobacco associated oral cancer are available, however; reports of cellular models for studying non-tobacco associated oral cancer are limiting. We report here the establishment and characterization of two novel buccal mucosal cancer cell lines 'GBC02' and 'GBC035' derived from non-tobacco users. MATERIALS AND METHODS Short tandem repeats (STR) profiling, Next-generation sequencing for whole-genome, exome and copy number alterations, immunofluorescence, flow-cytometry, proliferation, live-cell chemotaxis, 3D-spheroid formation, chemotherapy response, gene-expression microarray, gene-set enrichment analysis and xenograft development were performed. RESULTS Sources of the established cultures were matched to their donors through STR profiling. Genome sequence analysis revealed somatic mutations in TP53, CASP8, CDKN2A for GBC02 with deletions and amplifications encompassing CDKN2A, FAT1 and CCND1, PIK3CA, SOX2, EGFR, MYC genes, respectively. GBC035 harbored mutations in FAT1, NOTCH1, HRAS, CDKN2A, HLA-B, HLA-A genes. While GBC035 cells showed higher E-Cadherin positive cell-cell junctions and collective cell migration in chemotaxis; GBC02 cells were vimentin-positive and demonstrated individual cell migration. Further, exhibiting their relevance to preclinical research, GBC02 3D-spheroids demonstrated enrichment of development-related gene-signatures in microarray transcriptome analysis and were resistant to Cisplatin, but showed sensitivity to cancer stem cells-targeting drug, Salinomycin. Additionally, tumorigenic ability of GBC02 was demonstrated. CONCLUSIONS Altogether, we present here comprehensively characterized unique cell lines established from non-tobacco associated tumors, which may serve as models for preclinical investigations of oral cancers caused independent of tobacco usage.

Abstract
In this article, we highlight the evolution of a multimodal approach in the overall management of squamous cell carcinoma of the head and neck (SCCHN) in India; present advances in technology (newer surgical techniques), novel medical and radiotherapy (RT) approaches; review their roles for an integrated approach for treating SCCHN and discuss the current role of immunotherapy in SCCHN. For locally advanced (LA) SCCHN, the multidisciplinary approach includes surgery followed by RT, with or without chemotherapy (CT) or concurrent chemoradiotherapy. Improved surgical techniques of reconstruction and voice-preservation are being implemented. Advanced forms of high-precision conformal techniques like intensity-modulated radiotherapy are used to deliver highly conformal doses to tumors, sparing the surrounding normal tissue. Compared with RT alone, novel CT regimens and targeted therapeutic agents have the potential to improve locoregional control and survival and reduce treatment-induced toxicities. Several clinical trials have demonstrated efficacy, safety, and quality of life benefits of adding cetuximab to RT regimens in LASCCHN. Studies have also suggested a cetuximab-related laryngeal preservation benefit. At progression, platinum-based CT combined with cetuximab (a monoclonal anti-epidermal growth factor receptor antibody) is the only validated option available as the first-line therapy. Thus, an integrated multidisciplinary approach plays a key role in maximizing patient outcomes, reduction in treatment related morbidities that consequently impact quality of life of survivors.

Abstract
AbstractHead-and-neck cancers pose a serious economic burden, with most countries investing significant resources to reduce the incidence, primarily focusing on understanding addictive etiologies. The traditional literature focused on tobacco and alcohol use, with few studies on contemporary factors such as e-cigarette, waterpipe smoking, and human papillomavirus. This article attempts to collate and present an update on the globally identified etiologic factors.The aim of this study was to identify and review the addictive etiologic factors causing head-and-neck cancers.An electronic search was performed on Medline, Embase, and Google Scholar to identify the etiologies causing head-and-neck cancers and narrowed down on those driven by addiction. Further, we identified their constituents, mechanism of action, and the risks attributable to various forms of products.Substances identified included smoked and chewed tobacco, alcohol, mate, marijuana, areca nut and betel quid, and viruses. An alarming majority of youth are now utilizing these substances. Furthermore, migrant movements have led to the spread of traditional practices across the regions, especially from the Asian subcontinent.Ironically, despite modern advances and technology, we still see that a large proportion of population succumb to these cancers, emphasizing the need for more effective and targeted policies to combat this menace at the grassroots level.

Abstract
Non-communicable diseases contribute to 71% of the deaths worldwide, of which cancers rank second after cardiovascular diseases. Among all the cancers, head and neck cancers (HNC) are consequential in augmenting the global cancer incidence as well as mortality. Receptor tyrosine kinases (RTKs) are emphatic for the matter that they serve as biomarkers aiding the analysis of tumor progression and metastasis as well as diagnosis, prognosis and therapeutic progression in the patients. The extensive researches on HNC have made significant furtherance in numerous targeted therapies, but for the escalating therapeutic resistance. This review explicates RTKs in HNC, their signaling pathways involved in tumorigenesis, metastasis and stemness induction, the association of non-coding RNAs with RTKs, an overview of RTK based therapy and associated resistance in HNC, as well as a sneak peek into the HPV positive HNC and its therapy. The review extrapolates the cardinal role of RTKs and RTK based therapy as superior to other existing therapeutic interventions for HNC.

Abstract
BACKGROUND Recent advances in radiation technology has allowed to significantly reduce toxicity and improve the efficacy of radical radiotherapy in head and neck and oral squamous cell cancers. Insights into molecular biology of carcinogenesis has opened a window for identifying aggressive clinical situations that may benefit with larger clinical target volume (CTV ) margin, broader levels of nodal coverage, or alternative radiation sensitizers. AIM To evaluate the potential role of eukaryotic translation initiation factor 4E (elF4E) and p53 as predictive biomarkers in resected margins of head and neck and oral cancers. MATERIAL AND METHODS Forty patients with oral cancers and 26 patients with head and neck cancers were evaluated for p53 and eIF4E in their negative surgical margins, for pattern of distribution and outcome. RESULTS In oral cancers, 27 patients (67.5%) were positive for p53 and 10 (25%) for eIF4E in surgically negative margins. For head and neck cancer, the values were 13 (50%) for p53 and 9 (34.6%) for eIF4E. Twelve patients with oral cancers and 8 patients with head and neck cancers had local failure or death. The association with these biomarkers did not achieve statistical significance. However, adjuvant radiotherapy had a significant protective value. It improved median survival from 15 to 21 months in patients positive for p53 (P = 0.018) and from 12 to 20 months (P = 0.03) in those with eIF4E. There was no predictive association of subsite, tumor size, or nodal status. CONCLUSION The overexpression of p53 and eIF4E in pathologically negative margins may represent a subset of patients who would benefit from early initiation of adjuvant radiation and tailored intensity-modulated radiotherapy (IMRT).

Abstract
Background: Addition of nimotuzumab to weekly cisplatin and radiation improves outcomes in head and neck cancer. HPV negative oropharyngeal cancer has unsatisfactory treatment outcomes and is a candidate for escalation of treatment. We wanted to determine whether the addition of nimotuzumab to cisplatin-radiation could improve outcomes in these poor-risk tumors. Methods: This was a subgroup analysis of a phase 3 randomized study. In this study, locally advanced head and neck cancer patients undergoing definitive chemoradiation were randomly allocated to weekly cisplatin (30 mg/m2 IV)- radiation (66–70 Gy) {CRT arm} or nimotuzumab (200 mg weekly) -weekly cisplatin (30 mg/m2)-radiation (66–70 Gy) {NCRT arm}. The data of HPV negative oropharyngeal cancer was extracted from the database of this study for the analysis. HPV testing was done with p16 immunohistochemistry (IHC) staining and reported according to the CAP criteria. The outcomes assessed were progression-free survival (PFS), disease-free survival (DFS), locoregional control, and overall survival (OS). Interaction test was performed between the study arms and HPV status prior to doing any HPV specific analysis for each of the studied outcomes. Kaplan Meier estimates for 2 year OS with 95%CI was calculated. The hazard ratio was obtained using COX regression analysis. Results: We had 187 HPV negative oropharyngeal cancers, 91 in the CRT arm and 96 in NCRT arm. The interaction test was significant for PFS (p = 0.000), locoregional control (p = 0.007) and overall survival (p = 0.002) but not for DFS (p = 0.072). The 2- year PFS was 31.5% (95%CI 21.5–42) in CRT arm versus 57.2% (95%CI 45.8–67.1) in NCRT arm (HR -0.54; 95%CI 0.36–0.79, p = 0.002). The 2-year LRC was 41.4% (95%CI 29.8–52.6) in the CRT arm versus in 60.4% (95%CI 48.7–70.2) in the NCRT arm (HR -0.61; 95%CI 0.4–0.94, p = 0.024). The addition of nimotuzumab also lead to an improvement in 2-year OS from 39.0% (95%CI 28.4–49.6) to 57.6% (95%CI 46.3–67.4) (HR-0.63, 95%CI 0.43–0.92, p = 0.018). Conclusions: The addition of nimotuzumab to weekly cisplatin-radiation improves outcomes inclusive of OS in HPV negative oropharyngeal cancers.

Abstract
BACKGROUND Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. METHODS This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. RESULTS In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). CONCLUSIONS The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

Sarmah N, Baruah MN, Baruah S. Immune Modulation in HLA-G Expressing Head and Neck Squamous Cell Carcinoma in Relation to Human Papilloma Virus Positivity: A Study From Northeast India. Front Oncol 2019; 9:58. [PMID: 30859089 PMCID: PMC6397850 DOI: 10.3389/fonc.2019.00058] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Accepted: 01/21/2019] [Indexed: 12/14/2022] Open
Abstract
Background: Tumor specific ectopic expression of the immunomodulatory molecule, HLA-G is known to mediate immune tolerance and promote carcinogenesis. Viruses too employ strategies to evade immune surveillance. Considering the role of both HLA-G and HPV in tumor growth and progression, it is pertinent to investigate the relationship between HLA-G and HPV in context of immune modulation in HNSCC. Method: A hospital based case–control study was conducted in histopathologically confirmed HNSCC tissues. HLA-G isoform expression and HPV association studies were carried out and mRNA levels of HLA-G, markers of proliferation and differentiation (ki-67, keratin 18, cyclin D1), immune checkpoint molecules (IL-10, PD-1. TGF-β), SOCS (SOCS1 and SOCS3) and pro-inflammatory cytokine IFN-γ were determined. Results: Higher expression of HLA-G was noted in HPV positive tumors (5.14 fold, p = 0.002). HLA-G7 was the most frequent isoform (29/80) found in HNSCC particularly in HPV positive tumors (13/16). In HPV negative tumors, all the checkpoint molecules were upregulated along with pro–inflammatory IFN-γ. In contrast, in HPV positive tumors, IFN-γ expression was higher (2.12 fold) but levels of IL-10, PD-1, TGF-β, SOCS1 and SOCS3 were markedly lower (fold change of IL-10 = 0.37, PD1 = 0.41, TGF-β = 0.17, SOCS1 = 0.055, SOCS3 = 0.027). HPV positive tumors were more proliferative and differentiated with higher expression of ki-67 and keratin18 (6.25 fold, p = 0.079 and 10.62 fold, p = 0.009). Decreased expression of cyclin D1 was noted in HPV positive tumors (6.94 fold, p = 0.006) than HPV negative tumors (17.69 fold). Also, HLA-G7 expressing HPV positive tumors showed lowest expression of cyclin D1. Interestingly, SOCS showed normal expression in HLA-G7 expressing HPV negative tumors (1.2 and 1.4 fold). IFN-γ was downregulated in HPV positive tumors without HLA-G7 (0.31 fold). Conclusion: Our data suggests that SOCS were downregulated irrespective of HLA-G positivity and IFN- γ expression appeared to be mediated by HLA-G. SOCS are reported to have anti-tumor activity and also SOCS and soluble HLA-G are known to interfere with cell cycle progression. Hence, through regulating HLA-G expression, HPV positive tumors could mediate immune suppression by manipulating SOCS, IFN-γ, IL-10 and cyclin D1 pathways which needs further exploration.
