Objective To evaluate the efficacy of PHOTOFRIN-mediated photodynamic therapy (PDT) for treatment of diffuse ‘field cancerization’ and Tis-T2N0M0 squamous cell carcinoma (SqCCa) of the oral cavity and oral pharynx in patients not amenable to or that failed conventional head and neck treatment. Methods This is nonrandomized prospective study of 28 patients with field cancerization and early stage Tis-T2N0M0 squamous cell carcinoma of the oral cavity/oropharynx treated with PHOTOFRIN-mediated PDT. Intravenous PHOTOFRIN (porfimer sodium)(dose 2.0 mg/kg) was administered outpatient, followed 48–60 hours later by intraoperative photoactivation at 630nm via fiberoptic microlens surface delivery (surgical light dose 50–100 J/cm2). Results 21 of 27 patients (77%) have demonstrated complete remission (follow-up 1 month to 12 years). There were 5 patients that had partial remission with recurrence observed at 3, 3, 8, 22, and 23 months subsequently retreated with conventional therapy. All locally disease-free individuals were followed up between 1 to 144 months. 14 of the 21 patients in complete remission were disease-free for a period greater than 1 year following photodynamic therapy. Conclusions PHOTOFRIN-mediated photodynamic therapy can be used as a primary modality to treat Tis-T2N0 tumors of the oral cavity and oropharynx or for treatment for those that have failed prior surgery and/or radiation therapy. PDT allows for preservation of function and structure with absence of systemic toxicity, and patients may have multiple drug administrations and laser light retreatments for local disease control.

ABSTRACT Aim To evaluate the existing body of literature and impact of depth of invasion (DOI) in early-stage oral cavity squamous cell carcinoma (OCSCC) and its role in predicting occult cervical lymph node metastases. Background The prognosis for early-stage T1 to T2 disease OCSCC is relatively poor compared with other mucosal subsites within the head and neck. Primary tumor DOI can help prognosticate high-risk tumors for additional treatment. Review results There are unequivocal management implications in the literature demonstrating a role for elective neck dissection in early-stage OCSCC based on DOI. Following appropriate patient selection, there may be a role for sentinel lymph node biopsy in regional lymph node staging in early-stage OCSCC. Conclusion There are a multitude of studies demonstrating novel strategies to appropriately treat early-stage OCSCC, which are increasingly becoming standard of care. These strategies are altering the overall and disease-free survival of early-stage OCSCC. Despite advances, locoregional recurrence remains a challenge in this disease. Clinical significance Herein, the authors highlight a number of advances in the management of early-stage OCSCC as described in the literature, which are having an impact on disease-free and overall survival.

Background: Head and neck cancer is typically treated with surgery, radiotherapy, chemoradiation, or a combination of these treatments. This study aims to retrospectively analyse oncological outcomes, adverse events and toxicity of treatment with temoporfin-mediated photodynamic therapy at a single tertiary referral center. More specifically, in a selected group of patients with otherwise (functionally) inoperable oral or oropharyngeal head and neck squamous cell carcinoma.Methods: Twenty-six consecutive patients who received photodynamic therapy for oral or oropharyngeal squamous cell carcinoma from January 2002 until July 2019 at the University Hospitals Leuven were included. These were (1) patients with an accessible recurrent or new primary tumor in an extensively treated area of the head and neck, not suitable for standard treatment, or (2) patients that were judged medically unfit to undergo standard treatment modalities.Results: Complete tumor response immediately after PDT was obtained in 76.9% of cases. During follow-up, a proportion of CR patients did recur, to reach recurrence-free rates at six months, one year and two years of 60.6%, 48.5% and 32.3%. Local control at the PDT treated area was 42.3% with a median recurrence free interval time of 9 months. Recurrence-free interval was statistically more favorable for oropharyngeal squamous cell carcinoma (with or without oral cavity extension) in comparison to oral cavity squamous cell carcinoma alone (p < 0.001). During a median follow-up period of 27 months, we report new tumor activity in 80.8% of patients. Median overall and disease-specific survival time was 31 and 34 months, respectively. Most reported adverse events were pain after treatment and facial edema. At the end of follow-up, swallowing and upper airway functionality were preserved in 76.9 and 95.7% of patients, respectively.Conclusion: Photodynamic therapy is a valuable treatment option in highly selected patients with oral and/or oropharyngeal (functionally) inoperable head and neck squamous cell carcinoma. Treatment with this alternative modality can induce durable local control in an important fraction of treated patients, with an acceptable toxicity profile.

Abstract Background: Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. Objective: To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM) staging in oral cavity squamous cell carcinoma (OCSCC) patients and any impact of the same on survival. Materials and Methods: Retrospective chart review from year 2007 to 2013, at a tertiary care center. Statistical Analysis: All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA). Disease-free survival curves were generated using Kaplan-Meier algorithm. Results: One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2%) were males and 48 (37.8%) females with a mean age at presentation 43.6 years (29-79 years). The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Conclusion: Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.
