Diagnostic Challenge

Squamous cell carcinoma is the most common mucosal malignancy of the head and neck. Adenoid pseudo-angiosarcomatous SCC is a rare variant occurring commonly in the skin of the head and neck. However, involvement of oral cavity is extremely rare, with only few case reports in the English literature. Morphologically, the tumor shows marked acantholysis, with anastomozing channels mimicking vascular neoplasms. This variant represents a diagnostic challenge for pathologists, and immunohistochemical analysis remains essential for an accurate diagnosis. Herein, we describe the case of a pseudovascular SCC of the oral cavity in a 67 years old man with a brief revue of the literature to raise awareness on this rare variant; presenting diagnostic difficulties.

Well Differentiated

Verrucous carcinoma is a rare variant of well-differentiated squamous cell carcinoma. It usually occurs in the oral cavity, genital area, and sole. Verrucous carcinoma of the sole, also called epithelioma cuniculatum, often presents a diagnostic challenge both clinically and histopathologically. The authors report such a case that mimics infected epidermal cyst and gout clinically

The development of infra-clavicular lymph node metastasis from head and neck squamous cell carcinoma is an uncommon event. We present a rare case of bilateral axillary nodal metastasis that developed in a patient previously treated for a primary ethmoidal squamous cell carcinoma. To our knowledge, there have only been five case reports in the English literature, accounting for a total of 10 patients, which documented a clinically apparent metastasis to axillary lymph nodes from various head and neck malignancies. Significantly however, the simultaneous ipsilateral and contralateral lymphatic spread of disease from a tumour in the para-nasal sinus, so as to involve bi-axillary nodes, has not been previously reported. We discuss the possible pathogenesis and the prognostic significance of this manifestation.

Rare Malignancy

Leiomyosarcoma (LMS) of the trachea is an extremely rare malignancy with only a few reported cases in English literature. As such the diagnosis can be frequently missed or delayed. We present a case of a 69-year-old male who underwent tracheostomy for airway obstruction secondary to glottic squamous cell carcinoma and treated definitely with radiation therapy. Subsequently, the patient developed LMS of the tracheostomy site. The case further details multiple risk factors that could contribute to development of LMS including radiation exposure, prior malignancy, and chronic inflammation. These risk factors have been well established for LMS in other sites but less so in the head and neck region, which is the subject of our discussion. We also review the current guidelines for head and neck as well as limb sarcomas and discussed role of surgery or radiation and their accompanying challenges in management of this rare malignancy.

Research Model

Squamous cell carcinoma of oral cavity (OCSCC) accounts for approximately 25% of cases of head and neck squamous cell carcinoma (HNSCC). Tobacco and alcohol consumption are the main risk factors for both cancers. Surgical resection, combined with adjuvant radiotherapy or radiochemotherapy in patients with high risk of relapse, is the key element in management in the initial stages. However, despite the availability of aggressive multidisciplinary treatments, advanced resectable OCSCC carries poor prognosis; only half of the patients are disease-free 5 years after the surgery. Immunotherapy based on the use of immune checkpoint inhibitors has been proven to be effective in a wide variety of tumours, including recurrent and metastatic HNSCC. These positive results resulted in investigations into its effectiveness in earlier stages of the disease with OCSCC emerging as an interesting research model because of the accessible location of the tumours. This article reviews the potential advantages of emerging immunotherapeutic agents [mainly monoclonal antibodies against programmed cell death-1 ( PD-1) immune checkpoint inhibitors] as neoadjuvant treatment for OCSCC at locoregional stages as well as the ongoing clinical trials, challenges in evaluating tumour response, and possible predictive biomarkers of response with highlights regarding the role of oral microbiota as modulators of immune response. The efficacy and safety of anti- PD-1 drugs in these patients have been proven in preliminary trials. If there is a decrease in the relapse rate and an improvement in the overall survival after surgical resection in ongoing trials, preoperative immunotherapy may be established as a treatment option for patients with early stages of the disease.

Nodal Yield

AbstractBackground:Nodal metastasis is an important prognostic factor in head and neck squamous cell carcinoma. This study aimed to determine the average nodal basin yield per level of neck dissection, and to investigate if age, gender, body mass index, tumour size, depth of tumour invasion and p16 status influence nodal yield.Method:A retrospective review of 185 patients with head and neck squamous cell carcinoma generated 240 neck dissection specimens.Results:The respective mean nodal yields for levels I, II, III, IV and V were 5.27, 9.43, 8.49, 7.43 and 9.02 in non-cutaneous squamous cell carcinoma patients, and 4.2, 7.57, 9.65, 4.33 and 12.29 in cutaneous squamous cell carcinoma patients. Multiple regression analysis revealed that p16-positive patients with mucosal squamous cell carcinoma yielded, on average, 2.4 more nodes than their p16-negative peers (p = 0.04, 95 per cent confidence interval = 0.116 to 4.693). This figure was 3.84 (p = 0.008, 95 per cent confidence interval = 1.070 to 6.605) for p16-positive patients with oral cavity squamous cell carcinoma.Conclusion:In mucosal squamous cell carcinoma, p16-positive status significantly influenced nodal yield, with the impact being more pronounced in oral cavity squamous cell carcinoma patients.

6040 Background: Concomitant chemoradiotherapy (CT/RT) is the standard treatment for locally advanced head and neck squamous cell carcinoma. However, late toxicity is substantial.This phase II trial explores the feasibility and efficacy of combining neoadjuvant TPF and accelerated RT where the concomitant cytostatic component is replaced with cetuximab (E), a chimeric IgG1 mAb against EGFR. Methods: Patients (pts) had previously untreated stage III/IV M0,WHO 0–1, unresectable squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx and were scheduled for 2 cycles of TPF (docetaxel 75 mg/m2 and cisplatin 75 mg/m2 day 1 and 5-FU 1,000 mg/m2 96 hours CI) every 3 weeks followed by RT (68 Gy/4.5 weeks) with E given one week before (400 mg/m2) and weekly during RT (250 mg/m2). A brachytherapy boost of 8 Gy was given to pts with oral cavity or oropharyngeal tumours. Neck dissection was planned for pts with N2–3 and complete response (CR) at the primary tumour. Tumour response was evaluated according to RECIST with CT, MRI or PET/CT after CT and at 6 weeks follow up. Toxicity (CTC 3.0) and quality of life (EORTC QLQ 30) was registered during and after treatment. Results: From 070401 to 081115 68 pts were enrolled, 56 had stage IV disease (T4, n = 14, N3, n = 9). Median age 57, 60 males, 3 oral cavity, 44 oropharynx, 10 larynx, and 11 hypopharynx. 30 pts were followed beyond 6 weeks and evaluated for response and early toxicity: stage IV disease 24 (T4, n = 6, N3, n = 3), median age 60, 25 males, 18 oropharynx, 5 larynx, and 7 hypopharynx. Remissions after TPF/after RT: CR 1/10, PR 15/18, SD 14/1, and PD 1. TPF as prescribed: 28/30 (pat refusal 1, renal insuff 1, dose reduction 0/28); E as prescribed: 22/30 (dermatitis 4, hypersensitivity 3, liver tox 1). Vital tumour in resected specimen 0/13. Alive at follow-up 29/30 (1 local failure). Conclusions: TPF followed by RT concomitant with E is feasible with manageable toxicities. Dermatitis in the irradiated neck, at least with the present accelerated fractionation, is troublesome to some patients but does not interrupt treatment and heals rapidly. To dispose of feeding tubes after disappearance of acute mucosal reactions has not been a problem. Early survival results are promising. Toxicity and survival results will be updated.
