BackgroundThe evolution of radiotherapy over recent decades has reintroduced the hypofractionation for many tumor sites with similar outcomes to those of conventional fractionated radiotherapy. The use of hypofractionation in locally advanced head and neck cancer (LAHNC) has been already used, however, its use has been restricted to only a few countries. The aim of this trial was to evaluate the safety and feasibility of moderate hypofractionated radiotherapy (HYP-RT) with concomitant cisplatin (CDDP).MethodsThis single-arm trial was designed to evaluate the safety and feasibility of HYP-RT with concomitant CDDP in LAHNC. Stage III and IV patients withnonmetastatic disease were enrolled. Patients were submitted to intensity modulatedradiation therapy, which comprised 55 Gy/20 fractions to the gross tumor and44–48 Gy/20 fractions to the areas of subclinical disease. Concomitant CDDPconsisted of 4 weekly cycles of 35 mg/m2. The primary endpoints were the treatment completion rate and acute toxicity.ResultsTwenty patients were enrolled from January 2015 to September 2016, and 12 (60%) were classified as unresectable. All patients completed the total dose of radiotherapy, and 19 patients (95%) received at least 3 of 4 cycles of chemotherapy. The median overall treatment time was 29 days (27–34). Grade 4 toxicity was reported twice (1 fatigue and 1 lymphopenia). The rates of grade 3 dermatitis and mucositis were 30% and 40%, respectively, with spontaneous resolution. Nasogastric tubes were offered to 15 patients (75%) during treatment; 4 patients (20%) needed feeding tubes after 2 months, and only 1 patient needed a feeding tube after 12 months.ConclusionHYP-RT with concomitant CDDP was considered feasible for LAHNC, and the rate of acute toxicity was comparable to that of standard concomitant chemoradiation. A feeding tube was necessary for most patients during treatment. Further investigation of this strategy is warranted.Trial registrationClinicalTrials, NCT03194061.

Induction TP followed by cisplatin based-CRT was well-tolerated, safe, and had high overall response rate in selected patients with locally advanced HNSCC. © 2015 Wiley Periodicals, Inc. Head Neck 38: E970-E980, 2016.

The use of an ultrasonic scalpel was as safe as that of the conventional technique and had the advantage of a shorter operative time and lower postoperative drainage. Costs were not different between groups.

Fat-forming solitary fibrous tumor (SFT) is a rare variant of solitary fibrous tumor, a mesenchymal fibroblastic neoplasia with a particular branching hypervascular pattern. This tumor is usually classified as benign and only very few fat-forming SFTs with malignant histologic features have been reported. We report a histologically malignant fat-forming solitary fibrous tumor in a 61-year-old man, located in his neck. Ultrasonography examination was first performed showing a heterogeneous lesion, predominantly hyperechoic, with sound beam attenuation, containing two hypoechoic solid nodules. Magnetic resonance imaging and computed tomography examinations demonstrated a heterogeneous and predominantly adipose mass, containing post contrast enhancing solid nodules and thin septations. Treatment consisted of total removal of the lesion. Histologically, the tumor showed hypercellularity, numerous mitoses and cytological atypia, fulfilling the criteria for malignancy. The patient had no metastasis. This rare tumor may be confused with other fat-containing lesions on imaging examinations, mainly liposarcoma.

The authors report the results of a randomized clinical trial of antibiotic prophylaxis for post-operative infection following breast reconstruction with the transverse rectus abdominis myocutaneous (TRAM) flap. The aim was to evaluate the efficacy and tolerability of short-term parenteral prophylaxis with teicoplanin; the endpoint of the study was the reduction of wound contamination assessed by microbiologic culture of drain fluid. From October 1990 to March 1992, 38 patients were recruited: 20 patients were included in the antibiotic prophylaxis arm (teicoplanin i.v. 400 mg one hour before operation and in the following 12 h plus 200 mg i.v. at 24 h after operation) and 18 patients in the control group. Analysis of drain fluid showed a higher contamination (15/18=83%) in the control group (Staphylococcus epidermides, Streptococcus alfa-emoliticus, Enterobacter aerogenes, Peptostreptococcus magnus)as compared to the prophylaxis arm with teicoplanin (2/20=10%) (Staphylococcus coagulase-negative) (p< 0.0001). Moreover, 11 patients in the control group suffered from fever > 37.5 ° C as compared to one patient in the antibiotic prophylaxis group (p<0.0001); the post-operation stay was 13.3+4.3 and 9.0_+1.6 in the control and antibiotic arm, respectively (p = 0.0002). There were no antibiotic related side effect in this study. These results seem to confirm the value of parenteral short-term antibiotic prophylaxis of post-operative infection in this type of "clean" operative procedure.

Background: Tobacco or human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCC) represent different clinical and epidemiologic entities. This study investigated the prevalence of HPV-positive and HPV-negative OPSCC in a reference cancer hospital in Brazil and its association with clinical and demographic data, as well as its impact on overall survival. Methods: HPV infection was determined by p16-IHC in pre-treatment formalin-fixed paraffin-embedded samples from all patients with OPSCC diagnosed at Barretos Cancer Hospital between 2008 and 2018. The prevalence of HPV-positive cases and its temporal trend was assessed, and the association of clinical and demographic data with HPV infection and the impact on patient overall survival was evaluated. Results: A total of 797 patients with OPSCC were included in the study. The prevalence of HPV-associated tumors in the period was 20.6% [95% confidence interval, 17.5–24.0] with a significant trend for increase of HPV-positive cases over the years (annual percentage change = 12.87). In a multivariate analysis, the variables gender, level of education, smoking, tumor sublocation, region of Brazil, and tumor staging had a significant impact in HPV positivity, and a greater overall survival (OS) was observed in HPV-positive patients (5-year OS: 47.9% vs. 22.0%; P = 0.0001). Conclusions: This study represents the largest cohort of Brazilian patients with OPSCC characterized according to HPV status. We report significant differences in demographics and clinical presentation according to HPV status, and an increasing trend in prevalence for HPV-induced tumors. Impact: These findings can potentially contribute to a better stratification and management of patients as well as assist in prevention strategies.
