RESUMO

Purpose To report the results of the Trans Tasman Radiation Oncology Group randomized phase III trial designed to determine whether the addition of concurrent chemotherapy to postoperative radiotherapy (CRT) improved locoregional control in patients with high-risk cutaneous squamous cell carcinoma of the head and neck. Patients and Methods The primary objective was to determine whether there was a difference in freedom from locoregional relapse (FFLRR) between 60 or 66 Gy (6 to 6.5 weeks) with or without weekly carboplatin (area under the curve 2) after resection of gross disease. Secondary efficacy objectives were to compare disease-free survival and overall survival. Results Three hundred twenty-one patients were randomly assigned, with 310 patients commencing allocated treatment (radiotherapy [RT] alone, n = 157; CRT, n = 153). Two hundred thirty-eight patients (77%) had high-risk nodal disease, 59 (19%) had high-risk primary or in-transit disease, and 13 (4%) had both. Median follow-up was 60 months. Median RT dose was 60 Gy, with 84% of patients randomly assigned to CRT completing six cycles of carboplatin. The 2- and 5-year FFLRR rates were 88% (95% CI, 83% to 93%) and 83% (95% CI, 77% to 90%), respectively, for RT and 89% (95% CI, 84% to 94%) and 87% (95% CI, 81% to 93%; hazard ratio, 0.84; 95% CI, 0.46 to 1.55; P = .58), respectively, for CRT. There were no significant differences in disease-free or overall survival. Locoregional failure was the most common site of first treatment failure, with isolated distant metastases as the first site of failure seen in 7% of both arms. Treatment was well tolerated in both arms, with no observed enhancement of RT toxicity with carboplatin. Grade 3 or 4 late toxicities were infrequent. Conclusion Although surgery and postoperative RT provided excellent FFLRR, there was no observed benefit with the addition of weekly carboplatin.

RESUMO

Molecular profiling of metastatic disease may greatly influence the systemic therapy recommended by oncologists and chosen by patients, allowing treatment to be more targeted. Comprehensive care of patients with advanced breast cancer now includes percutaneous image-guided biopsy if this has the potential to influence systemic treatment [1]. Interventional radiologists can contribute significantly to the care of patients affected by breast cancer, in diagnostic and supportive procedures and importantly also in treatment. Interventional radiologists carry out image guided percutaneous biopsies not only of the primary tumour but also of metastases. They insert percutaneous ports and tunnelled central venous catheters. They ablate painful bone metastases, and can treat or prevent pathological fractures. Most importantly they can ablate liver metastases in patients with limited or oligometastatic disease. The inhomogeneity and variety of cell populations in metastatic tumours from breast cancer, which is an important consideration in systemic therapy, is not an important consideration in the treatment of metastatic tumours using percutaneous ablative techniques, which are the major focus of this article. The treatment of primary tumours in the breast is also being explored, but is considered in its infancy at this stage.

RESUMO

BACKGROUND: Swallowing and nutrition guidelines for patients with head and neck cancer are available for identification of proactive gastrostomy placement in patients with high nutritional risk. The purpose of this study was to investigate improvements to the validity of these guidelines. METHODS: A multivariate analysis was fitted to the original dataset (n = 501) to examine the variables that may predict gastrostomy placement (eg, tumor site, treatment, sex, and age). Using these factors, the high risk category was modified and retrospectively validated in the same cohort to provide new measures of sensitivity and specificity. RESULTS: The following were positive predictors of gastrostomy placement: T3 (p = .01), T4 (p < .001), and chemoradiotherapy (p < .001). Laryngeal (p = .02) and skin cancer (p < .001) were negative predictors. Modification of the high risk definition improved sensitivity to 58% and maintained specificity at 92%. CONCLUSION: Minor modifications to the high risk definition in the guidelines have improved the guideline sensitivity for future use. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1163-E1171, 2016.

RESUMO

BACKGROUND: The "Swallowing and Nutrition Guidelines for Patients with Head and Neck Cancer" were developed to guide early identification and management of dysphagia and nutritional risk before, during, and after cancer treatment. The purpose of this study was to validate these guidelines. METHODS: Patients attending a Combined Head and Neck Clinic at a major tertiary hospital in 2007 to 2008 were assessed using the guidelines, with high-risk category patients recommended for proactive gastrostomy. Data were collected on guideline adherence, gastrostomy tube insertion, and weight. Sensitivity, specificity, and positive predictive value were calculated for validation. RESULTS: Proactive gastrostomy tubes were inserted in 173 of 501 patients (25%). Overall guideline adherence was 87%. High-risk category adherence was 75%. Validation outcomes were sensitivity 54%, specificity 93%, and positive predictive value 82%. CONCLUSION: The risk categories in the guidelines are valid to assist early identification of swallowing and nutritional risk and guide decision-making on proactive gastrostomy tube insertion.
