Treatment of the neck in residual/recurrent disease after chemoradiotherapy for advanced primary laryngeal cancer.

Concomitant chemoradiotherapy (CRT) is extensively used as primary organ preservation treatment for selected advanced laryngeal squamous cell carcinomas (LSCC). The oncologic outcomes of such regimens are comparable to those of total laryngectomy followed by adjuvant radiotherapy. However, the management of loco-regional recurrences after CRT remains a challenge, with salvage total laryngectomy being the only curative option.

A new prognostic model in chemotherapy-treated patients with recurrent or metastatic head and neck cancer: An analysis of ECOG-ACRIN E1305.

Introduction: For patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) periodic reassessment of prognostic factors provides valuable information that can aid in patient stratification.

Patients And Methods: This post hoc analysis included all patients with R/M HNSCC enrolled in the ECOG-ACRIN E1305 phase III clinical trial who received first-line treatment with platinum-containing chemotherapy doublet with or without bevacizumab. Overall survival (OS) was estimated using the Kaplan-Meier method.

Novel Immunotherapeutic Approaches to Treating HPV-Related Head and Neck Cancer.

Head and neck cancer (HNC) is the seventh most common malignancy, with oropharyngeal squamous cell carcinoma (OPSCC) accounting for a majority of cases in the western world. While HNC accounts for only 5% of all cancers in the United States, the incidence of a subset of OPSCC caused by human papillomavirus (HPV) is increasing rapidly. The treatment for OPSCC is multifaceted, with a recently emerging focus on immunotherapeutic approaches.

Phase III Prospectively Randomized Trial of Perioperative 5-FU After Curative Resection for Colon Cancer: An Intergroup Trial of the ECOG-ACRIN Cancer Research Group (E1292).

Background: Studies suggest that adjuvant chemotherapy should be initiated at the earliest possible time. The Eastern Cooperative Oncology Group (ECOG) and Intergroup evaluated the effect of perioperative fluorouracil (5-FU) on overall survival (OS) for colon cancer.

Patients And Methods: This phase III trial randomized patients to receive continuous infusional 5-FU for 7 days starting within 24 h after curative resection (arm A) or no perioperative 5-FU (arm B).

TP53 mutations in head and neck cancer.

Head and neck squamous cell carcinomas (HNSCCs) arising in the mucosal linings of the upper aerodigestive tract are highly heterogeneous, aggressive, and multifactorial tumors affecting more than half a million patients worldwide each year. Classical etiological factors for HNSCC include alcohol, tobacco, and human papillomavirus (HPV) infection. Current treatment options for HNSCCs encompass surgery, radiotherapy, chemotherapy, or combinatorial remedies.

De-escalation studies in HPV-positive oropharyngeal cancer: How should we proceed?

Human papilloma virus (HPV) is a well-established causative factor in a subset of squamous cell carcinomas of the head and neck (HNSCC). Although HPV can be detected in various anatomical subsites, HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) is the most common HPV-related malignancy of the head and neck, and its worldwide incidence is constantly rising. Patients with OPSCC are generally younger, have less co-morbidities and generally have better prognosis due to different biological mechanisms of carcinogenesis.

A systematic review and recommendations on the use of plasma EBV DNA for nasopharyngeal carcinoma.

Introduction: Nasopharyngeal carcinoma (NPC) is an endemic malignancy in Southeast Asia, particularly Southern China. The classical non-keratinising cell type is almost unanimously associated with latent Epstein-Barr virus (EBV) infection. Circulating plasma EBV DNA can be a useful biomarker in various clinical aspects, but comprehensive recommendations and international guidelines are still lacking.

ECOG-ACRIN 2399: analysis of patient related outcomes after Chemoradiation for locally advanced head and neck Cancer.

Background: We conducted a correlative study for E2399, a function preservation trial for resectable locally advanced oropharynx and larynx cancer, to prospectively assess effects of chemoradiation (CCR) on quality of life (QOL), swallowing and voice. We correlated the results of swallow assessments done via questionnaires and objective assessments by modified barium swallow (MBS).

Methods: The Functional Assessment of Cancer-HN (FACT-HN), the Performance Status Scale - Head and Neck (PSS-HN), swallow assessments (including modified barium swallow studies), and voice assessments: Voice Handicap Index (VHI), the Voice Disability Assessment (VDA), and American Speech-Language Hearing Association's Functional Communication Measure (FCM) were conducted at baseline and periodically post-treatment for 2 years.

GEAMP, a novel gastroesophageal junction carcinoma cell line derived from a malignant pleural effusion.

Gastroesophageal junction (GEJ) cancer remains a clinically significant disease in Western countries due to its increasing incidence, which mirrors that of esophageal cancer, and poor prognosis. To develop novel and effective approaches for prevention, early detection, and treatment of patients with GEJ cancer, a better understanding of the mechanisms driving pathogenesis and malignant progression of this disease is required. These efforts have been limited by the small number of available cell lines and appropriate preclinical animal models for in vitro and in vivo studies.

Prognostic and predictive factors in recurrent and/or metastatic head and neck squamous cell carcinoma: A review of the literature.

The pattern of clinical behaviour and response to treatment of recurrent and/or metastatic head and neck squamous cell carcinoma is heterogeneous. Treatment strategies that can be employed vary from potentially curative salvage surgery and re-irradiation to palliative systemic therapies and best supportive care. The advent of new therapeutic options, in terms of more sophisticated surgical approaches and techniques, highly conformal and precise radiation techniques and immunotherapy may offer improved control of disease and longer survival.

PTEN loss is associated with resistance to cetuximab in patients with head and neck squamous cell carcinoma.

Introduction: Cetuximab, a monoclonal antibody to the epidermal growth factor receptor (EGFR), extends survival in combination with standard therapy in head and neck squamous cell carcinoma (HNSCC). However, as effects are modest, and patients experience side effects, a biomarker to predict resistance and personalize therapy is needed. Activation of signaling pathways downstream from receptor tyrosine kinases predicts resistance to such therapies in other cancers.

Pattern of planned systemic therapy usage in newly diagnosed, nonmetastatic squamous cell carcinoma of the head and neck in a commercially insured population in the United States.

Background: We analyzed systemic therapy plans submitted for commercially insured patients with untreated, newly diagnosed squamous cell carcinoma of the head and neck (SCCHN) to investigate patterns of practice.

Methods: Consecutive chemotherapy treatment plans were submitted using Eviti Connect (https://www.marylandphysicianscare.

Phase II Study of Irinotecan Plus Panitumumab as Second-Line Therapy for Patients with Advanced Esophageal Adenocarcinoma.

Lesson Learned: Panitumumab plus irinotecan is not active for the treatment of esophageal adenocarcinoma.

Background: Esophageal adenocarcinoma (EAC) is a lethal cancer with increasing incidence. Panitumumab (Pa) is a fully humanized IgG2 monoclonal antibody against human EGFR.

Radiation Therapy for Oropharyngeal Squamous Cell Carcinoma: American Society of Clinical Oncology Endorsement of the American Society for Radiation Oncology Evidence-Based Clinical Practice Guideline.

Purpose The American Society for Radiation Oncology (ASTRO) produced an evidence-based guideline on radiation therapy in oropharyngeal squamous cell carcinoma (OPSCC) that was determined to be relevant to the American Society of Clinical Oncology (ASCO) membership. After applying standard critical appraisal policy and endorsement procedures, ASCO chose to endorse the ASTRO guideline. Methods The ASTRO guideline was reviewed by ASCO content experts for clinical accuracy and by ASCO methodologists for developmental rigor.

Response assessment after induction chemotherapy for head and neck squamous cell carcinoma: From physical examination to modern imaging techniques and beyond.

Significant correlations between the response to induction chemotherapy and success of subsequent radiotherapy have been reported and suggest that the response to induction chemotherapy is able to predict a response to radiotherapy. Therefore, induction chemotherapy may be used to tailor the treatment plan to the individual patient with head and neck cancer: following the planned subsequent (chemo)radiation schedule, planning a radiation dose boost, or reassessing the modality of treatment (eg, upfront surgery). Findings from reported trials suggest room for improvement in clinical response assessment after induction chemotherapy, but an optimal method has yet to be identified.

Organ preservation with chemoradiation in advanced laryngeal cancer: The problem of generalizing results from randomized controlled trials.

Background: The primary goal of treatment in advanced laryngeal cancer is to achieve optimal oncologic outcomes while preserving function and quality of life. Combination of chemotherapy and radiation has been popularized as an alternative to surgery for patients facing total laryngectomy. However, survival analyses from large, population-based databases have not duplicated results reported from randomized trials.

Head and Neck Squamous Cell Carcinoma: Update on Epidemiology, Diagnosis, and Treatment.

Squamous cell carcinoma arises from multiple anatomic subsites in the head and neck region. The risk factors for development of cancers of the oral cavity, oropharynx, hypopharynx, and larynx include tobacco exposure and alcohol dependence, and infection with oncogenic viruses is associated with cancers developing in the nasopharynx, palatine, and lingual tonsils of the oropharynx. The incidence of human papillomavirus-associated oropharyngeal cancer is increasing in developed countries, and by 2020, the annual incidence could surpass that of cervical cancer.
