Abstract
Cetuximab (EGFR-targeted IgG1 monoclonal antibody) has shown to improve the treatment outcomes in head and neck cancer. The evidence on the beneficial outcomes of cetuximab with radiotherapy (RT) in unresectable patients of locally advanced squamous cell carcinoma of head and neck (LA-SCCHN) is limited in real-life practice. The present study evaluated the treatment outcomes of cetuximab concurrent with RT in Indian patients with unresectable LA-SCCHN. We retrospectively reviewed fifty-one patients with unresectable LA-SCCHN between January 2013 and December 2017, who were treated with cetuximab concurrently with RT. Tumor response and disease-free survival (DFS) were estimated. Tumor response using RECIST (1.1) criteria reported complete response in 66.7%, partial response in 31.4% and progressive disease in 1.9% of the patients. The overall response rate was 98%. The 1-year and 2-year DFS was 85% and 69% respectively. The median DFS was significantly better in stage 3 than stage 4. The most common toxicity observed was mucositis and skin reactions (grade 3). Cetuximab concurrent with RT was effective in Indian patients with unresectable, LA-SCCHN and had an acceptable toxicity profile in real-life practice. The real-life beneficial evidence of the combination is consistent with the results documented in the randomized controlled trials.

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
Concurrent chemoradiotherapy with high-dose cisplatin (100 mg/m2 every 3 weeks) is the preferred regimen with curative intent for patients with unresected locally advanced squamous cell carcinoma of the head and neck (LA SCCHN). This treatment is associated with acute and late toxicities, including myelosuppression, severe nausea/vomiting, irreversible renal failure, hearing loss, and neurotoxicity. Because of cisplatin's safety profile, treatment adherence to high-dose cisplatin can be suboptimal. Patients commonly receive less than the total cumulative target dose of 300 mg/m2 or the minimum recommended dose of 200 mg/m2, which can have a negative impact on locoregional control and survival. Alternatively, cetuximab plus radiotherapy may be most suitable for patients at high risk of non-adherence to high-dose cisplatin. We discuss the baseline characteristics dictating the unsuitability/borderline unsuitability of cisplatin and the available alternative evidence-based treatment regimens for patients with LA SCCHN. We non-systematically reviewed published phase II and III trials and retrospective analyses of high-dose cisplatin-based chemoradiation in LA SCCHN conducted between 1987 and 2018, focusing on recent key phase III studies. We defined the baseline characteristics and associated prescreening tests to determine unsuitability and borderline unsuitability for high-dose cisplatin in combination with radiotherapy in patients with LA SCCHN. Patients with any pre-existing comorbidities that may be exacerbated by high-dose cisplatin treatment can be redirected to a non-cisplatin-based option to minimize the risk of treatment non-adherence. High-dose cisplatin plus radiotherapy remains the preferred treatment for fit patients with unresected LA SCCHN; patients who are unsuitable or borderline unsuitable for high-dose cisplatin could be identified using available tests for potential comorbidities and should be offered alternative treatments, such as cetuximab plus radiotherapy.

Abstract
Radiotherapy is one of the most common form of treatment in oncology care. Indeed, radiotherapy proved to be very effective in treating a wide range of malignancies. Nevertheless, certain tumours are intrinsically radioresistant or may evolve to become radioresistant. Resistance to radiotherapy is often associated with dysregulated DNA damage response and repair. Recently, a number of strategies have been developed to improve radiotherapy efficacy by targeting the DNA damage response and repair pathways. Ongoing clinical trials showed the potential of some of these approaches in enhancing radiotherapy, but also highlighted the possible limitations. Here, we will describe (i) the main mechanisms involved in double-strand break repair; (ii) available strategies that target these DNA repair processes to improve radiotherapy and (iii) the clinical outcomes and challenges that have emerged so far.

Abstract
The epidermal growth factor receptor (EGFR) is one of the most comprehensively studied molecular targets in head and neck squamous cell carcinoma (HNSCC). However, inherent and acquired resistance are serious problems and are responsible for limited clinical efficacy and tumor recurrence. In this study, we evaluated the feasibility of immuno-positron emission tomography (PET) imaging and radioimmunotherapy (RIT) with 64Cu-/177Lu-PCTA-cetuximab in cetuximab-resistant SNU-1066 HNSCC xenografted model. The cellular uptake of 64Cu/177Lu-3,6,9,15-tetraazabicyclo[9.3.1]-pentadeca-1(15),11,13-triene-3,6,9,-triacetic acid (PCTA)-cetuximab showed good correlation with western blot and flow cytometry analysis in EGFR expression level of various HNSCC cells. 177Lu-PCTA-cetuximab selectively killed cetuximab-resistant SNU-1066 cells in vitro. 64Cu-/177Lu-PCTA-cetuximab specifically accumulated in SNU-1066 tumor and those uptakes were peaked at 48 h and 7 day, respectively in biodistribution, PET and single-photon emission computed tomography/computed tomography (SPECT/CT) imaging. RIT with single dose of 177Lu-PCTA-cetuximab exhibited significant tumor regression and markedly reduced 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) uptake, compared to other groups. Proliferation index were dramatically decreased and apoptotic index increased in RIT group. These results suggest that a diagnostic and therapeutic convergence radiopharmaceutical, 64Cu-/177Lu-PCTA-cetuximab has the potential of target selection using immuno-PET imaging and targeted therapy by RIT in EGFR expressing cetuximab-resistant HNSCC tumors.

Abstract
We review clinical trials of squamous cell carcinoma of the head and neck (SCCHN) to address the current and potential uses of cetuximab (CTX). PubMed was reviewed to identify papers published between 2010 and 2016. The search terms used were "cetuximab" and "head and neck cancer." A total of 634 articles were identified. Phase II or III studies with CTX in patients with advanced SCCHN without treatment or with recurrent/metastatic tumors were selected. Forty-six registries were obtained. Information was critically reviewed and relevant information presented. As definitive treatment of advanced squamous cells carcinomas and as palliative treatment of recurrent/metastatic disease, CTX alone or associated with chemotherapy and/or radiotherapy is an alternative to chemoradiotherapy because of its distinct and favorable toxicity profile.

Abstract
OBJECTIVE This study aimed to investigate the efficacy of induction chemotherapy followed by concurrent chemotherapy and helical tomotherapy in patients with T4b squamous cell carcinoma of the nasal cavity and paranasal sinus in regard to orbital organ preservation and quality of life. METHODS Clinical data of 28 cases of patients with orbital involvement of T4b squamous cell carcinoma of the nasal cavity and paranasal sinus who received multimodal treatment for orbital organ preservation between May 2008 and September 2015 were retrospectively analysed. The treatment efficacy and side effects were assessed. The study included 18 male and 10 female patients. All patients were treated with induction chemotherapy followed by concurrent chemoradiotherapy and/or epidermal growth factor receptor inhibitor. Helical tomotherapy was applied as radiotherapy. Adverse reactions to the chemotherapy were assessed according to Common Terminology Criteria for Adverse Events, Version 4. The overall survival rate, local control rate and rate of effective orbital preservation were calculated using the Kaplan-Meier method. RESULTS All patients completed the planned chemotherapy, and 27 (96.4%) of the patients completed the planned radiotherapy cycle. After the multimodal treatment, the 3-year overall survival, local control rate and rate of effective orbital preservation of the patients were 59.2%, 80.2% and 77.8%, respectively. CONCLUSIONS Multimodal treatment could preserve the orbital organs of patients with T4b squamous cell carcinoma of the nasal cavity and paranasal sinus, achieve relatively ideal organ protection and survival rates and improve the quality of life of patients with advanced squamous cell carcinoma of the nasal cavity and paranasal sinus, thus providing a new treatment option for these patients.

Abstract
The epidermal growth factor receptor (EGFR) has evolved over years into a main molecular target for the treatment of different cancer entities. In this regard, the anti-EGFR antibody cetuximab has been approved alone or in combination with: (a) chemotherapy for treatment of colorectal and head and neck squamous cell carcinoma and (b) with external radiotherapy for treatment of head and neck squamous cell carcinoma. The conjugation of radionuclides to cetuximab in combination with the specific targeting properties of this antibody might increase its therapeutic efficiency. This review article gives an overview of the preclinical studies that have been performed with radiolabeled cetuximab for imaging and/or treatment of different tumor models. A particularly promising approach seems to be the treatment with therapeutic radionuclide-labeled cetuximab in combination with external radiotherapy. Present data support an important impact of the tumor micromilieu on treatment response that needs to be further validated in patients. Another important challenge is the reduction of nonspecific uptake of the radioactive substance in metabolic organs like liver and radiosensitive organs like bone marrow and kidneys. Overall, the integration of diagnosis, treatment and monitoring as a theranostic approach appears to be a promising strategy for improvement of individualized cancer treatment.
