Abstract
Cisplatin is the standard for the chemoradiation of squamous cell carcinoma of the head and neck (HNSCC). Many patients cannot receive cisplatin due to impaired renal function. This study investigated carboplatin as an alternative option. In total, 131 patients assigned to two courses of cisplatin (20 mg/m2/d1--5 or 25 mg/m2/d1-4) were matched to 45 patients not suitable for cisplatin and receiving carboplatin (AUC 1.0/d1-5 or AUC 1.5/d1-4). The endpoints included loco-regional control (LRC), metastases-free survival (MFS), overall survival (OS), toxicities, and the completion of chemotherapy. The patients in the carboplatin group were significantly older and had more G3 tumors. Otherwise, the baseline characteristics were balanced. The LRC rates at 2 and 3 years were 77% and 76% in the cisplatin group vs. 69% and 65% in the carboplatin group (p = 0.21). The MFS rates were 83% and 78% vs. 78% and 74% (p = 0.34) and the OS rates 83% and 79% vs. 83% and 75% (p = 0.64), respectively. The outcomes were not significantly different in the subgroups receiving definitive or adjuvant chemoradiation. No significant differences were found regarding toxicities. Non-significantly more patients in the carboplatin group completed their chemotherapy (78% vs. 66%, p = 0.15). Carboplatin was associated with similar outcomes and toxicities as cisplatin, although these patients had worse renal function, more aggressive tumors, and were older. Given the limitations of this study, carboplatin appears an option for patients not suitable for cisplatin.

Cancer Radiother 2020; 24:559-566. [PMID: 32753240 DOI: 10.1016/j.canrad.2020.05.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Accepted: 05/22/2020] [Indexed: 01/16/2023]
Abstract
PURPOSE Patients with synchronous metastatic head and neck squamous cell carcinomas often present associated locoregional symptoms and a risk of life-threatening primary tumour progression. Few data have been published about the use of radiation therapy in the management of newly diagnosed metastatic disease associated with advanced locoregional disease. In this article, we aim to determine the role of radiation therapy of the primary tumour in the overall therapeutic strategy for these diseases. We further address radiation therapy modalities (technique, volumes, and fractionation) in such a context. MATERIAL AND METHODS We conducted a literature survey on locoregional radiotherapy for newly diagnosed metastatic head and neck squamous cell carcinomas. RESULTS Several retrospective studies have reported that locoregional radiotherapy is associated with improved overall survival of patients with synchronous metastatic head and neck squamous cell carcinomas. However, data about modalities such as timing of radiotherapy in the overall strategy, dose, fractionation and delineation volumes are scarce. Two schematic situations can be distinguished with respect to prognosis and treatment adaptations: polymetastatic/bulky or oligometastatic disease. In polymetastic/bulky disease associated with poor prognosis, standard-of-care is systemic therapy, but locoregional radiotherapy can be discussed either upfront, mainly for symptomatic palliation, or as consolidation after downsizing obtained by systemic therapy. As for oligometastatic disease, with the rise in use of efficacious and well-tolerated local ablative treatments of metastases, aggressive curative-intent locoregional radiotherapy can be considered with or without systemic therapy. CONCLUSION Because locoregional disease is a major cause of disease failure in patients with synchronous metastatic head and neck squamous cell carcinomas, aggressive locoregional radiation therapy to the primary tumour may be discussed in the initial management of the disease where systemic therapy alone may not induce sufficient primary tumour reduction. With recent technological advances in radiotherapy, the delivery of radiotherapy is safe and feasible even in metastatic setting. Clinical trials assessing radiotherapy use for metastatic head and neck squamous cell carcinomas are warranted.

Abstract
Purpose Radiochemotherapy (RCT) is an effective standard therapy for locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Nonetheless, toxicity is common, with patients often requiring dose modifications. Methods To investigate associations of RCT toxicities according to CTCAE version 5.0 and subsequent therapy modifications with short- and long-term treatment outcomes, we studied all 193 patients with HNSCC who received RCT (70 Gy + platinum agent) at an academic center between 03/2010 and 04/2018. Results During RCT, 77 (41%, 95% CI 34–49) patients developed at least one ≥ grade 3 toxicity, including seven grade 4 and 3 fatal grade 5 toxicities. The most frequent any-grade toxicities were xerostomia (n = 187), stomatitis (n = 181), dermatitis (n = 174), and leucopenia (n = 98). Eleven patients (6%) had their radiotherapy schedule modified (mean radiotherapy dose reduction = 12 Gy), and 120 patients (64%) had chemotherapy modifications (permanent discontinuation: n = 67, pause: n = 34, dose reduction: n = 7, change to other chemotherapy: n = 10). Objective response rates to RCT were 55% and 88% in patients with and without radiotherapy modifications (p = 0.003), and 84% and 88% in patients with and without chemotherapy modifications (p = 0.468), respectively. Five-year progression-free survival estimates were 20% and 50% in patients with and without radiotherapy modifications (p = < 0.001), and 53% and 40% in patients with and without chemotherapy modifications (p = 0.88), respectively. Conclusions Reductions of radiotherapy dose were associated with impaired long-term outcomes, whereas reductions in chemotherapy intensity were not. This suggests that toxicities during RCT should be primarily managed by modifying chemotherapy rather than radiotherapy.

Abstract
OBJECTIVE To assess the feasibility in routine practice of postoperative chemoradiotherapy in head and neck squamous cell carcinoma (HNSCC) at high risk of recurrence. METHOD A single-center retrospective study recruited all patients receiving postoperative cisplatin chemoradiotherapy for HNSCC at high risk of recurrence. The main endpoints were the rate of complete postoperative chemoradiotherapy and the impact of various clinical factors. Secondary endpoints comprised the impact of completion of therapy on survival and on acute and late toxicity. RESULTS One hundred and six patients were included. 24.5% showed severe comorbidity. Chemoradiotherapy was complete in 61 patients (57.5%). Radiation therapy was interrupted for >3 days in 16 patients (15.1%). The 3rd concomitant cisplatin course could not be implemented in 34 patients (32.1%). Low pre-treatment glomerular filtration rate was significantly associated (p=0.003) with treatment interruption; >5% weight-loss during treatment showed suggestive association (p=0.026). Completion of treatment was not associated with any significant difference in overall survival (p=0.441) or progression-free survival (p=0.81). 14.9% of patients showed post-treatment kidney failure; there were 10 cases of osteoradionecrosis (9.4%). CONCLUSION The rate of complete postoperative chemoradiotherapy was comparable to that reported in clinical trials, despite frequent comorbidity and poor nutritional status. Early nutritional support is a key factor for treatment under optimal conditions.

Abstract
Background Based on previous observations that the nutraceutical CELLFOOD™ (CF), the 'physiological modulator' that aimed to make oxygen available 'on demand', inhibits the growth of cancer cells, this study was designed to investigate the role of CF in the regulation of hypoxia-inducible factor 1 alpha (HIF1α) and its correlated proteins, phosphoglycerate kinase 1 and vascular endothelial growth factor. Our idea was that CF, acting on HIF1α, in combination with current anticancer therapies could improve their effectiveness. Methods To evaluate the effect of CF in association with radiotherapy and chemotherapy, different human cancer cell lines and mice with mesothelioma were analysed by tumour growth, clonogenic assay, western blot and immunohistochemical analysis. Results CF in combination with radiation with or without cisplatin increases the death rate of cancer cells. In vivo, 70% of mice treated with CF before the mesothelioma graft did not show any tumour growth, indicating a possible preventive effect of CF. Moreover, in mouse mesothelioma xenografts, CF improves the effect of radiotherapy also in combination with chemotherapy treatment. Immunohistochemical analysis of tumour explants showed that HIF1α expression was reduced by the combination of CF and radiotherapy treatment and even more by the combination of CF and radiotherapy and chemotherapy treatment. Mechanistically, CF increases the fraction of oxygenated cells, making the radiotherapy more effective with a greater production of reactive oxygen species (ROS) that in turn, reduce the HIF1α expression. This effect is amplified by further increase in ROS from chemotherapy. Conclusions Collectively, results from preclinical trials suggest that CF could be a useful intervention to improve the efficacy of radiotherapy or combined treatment strategies and could be a promising treatment modality to counteract cancer.

Abstract
OBJECTIVES Radiological extranodal extension (rENE) upon CT is obtained before concurrent chemoradiation therapy (CCRT) for head and neck squamous cell carcinoma (HNSCC). We evaluated the prognostic value of rENE, rather than pathologically proven ENE, in patients who received CCRT for HNSCC. MATERIALS AND METHODS We reviewed 117 patients. We divided the patients into rENE(+) and rENE(-) groups and evaluated overall survival (OS) and disease-specific survival (DSS), and factors affecting these outcomes. RESULTS Median follow-up was 37.4 months; 31 patients (26.2%) died and 26 (22.2%) had recurrence. Thirty patients were rENE(+) and these had worse 5-year OS (74% vs. 94%, p < .01) and DSS (42% vs. 84%, p < .01) rates compared with the rENE(-) group (n = 87). rENE (hazard ratio [HR] 3.57, p < .05) and complete response (HR 3.55, p < .05) affected OS. Clinical T stage (HR 2.86, p < .05), rENE (HR 2.88, p < .05), and complete response (HR 7.03, p < .01) affected DSS. rENE(+) increased risk of incomplete response (IR) compared with the rENE(-) group (p < .05). CONCLUSIONS CT findings suggesting ENE predicts treatment response to CCRT and prognosis, and could be used to determine the treatment modality for HNSCC.

Abstract
Objectives Concurrent chemoradiotherapy is standard of care in locally advanced oropharyngeal cancer (LA-OPC). This treatment regimen results in significant acute toxicities. This study investigates the effect of treatment-related toxicity on patient outcomes. Methods Patient information was retrospectively collected for patients treated for LA-OPC between 2007 and 2014. Factors analyzed included age, gender, pretreatment ECOG performance status, smoking history, patient BMI prior to and following treatment, tumor histology, disease stage, disease recurrence, incidence, and timing of feeding tube placement, radiation dose received, chemotherapy regimen used and if it was completed, and patient survival. All statistical analysis was provided through the University of Nebraska Medical Center Department of Biostatistics. Results 74 patients were identified with a median follow-up of 3.4 years and a median age of 58.5. Most patients were male (87.8%) and had squamous cell histology (98.7%). Most patients underwent chemoradiotherapy alone (98.6%) and received concurrent cisplatin (78.4%) with approximately half (53.4%) receiving all planned chemotherapy. Upon multivariate analysis, both disease-free (DFS) and overall survival (OS) rates were improved by lower pretreatment BMI, increased weight lost during treatment, and lack of percutaneous endoscopic gastrostomy (PEG) tube placement prior to treatment initiation. Neither DFS nor OS was impacted by placement of a PEG tube during active treatment. Conclusion These data suggest that weight loss and PEG tube placement during chemoradiotherapy for LA-OPC, presumably due to treatment-associated mucositis and xerostomia, are not associated with worse outcomes.
