This study aimed to investigate the outcome in patients with aspiration pneumonia during definitive concurrent chemoradiotherapy for head and neck cancer. The data of 595 patients with head and neck cancer treated by chemoradiotherapy were reviewed. Forty-one patients were identified as developing symptomatic aspiration pneumonia during treatment and were analysed for this study. The definition of symptomatic aspiration pneumonia fit three criteria: (1) at least one event of aspiration during the treatment or evidence of grade 2 or above dysphagia during treatment; (2) clinical or radiographic signs of pneumonia or pneumonitis; and (3) no evidence of grade 4 haematological toxicity before the outbreak of pneumonia. Termination of allocated radiotherapy was noted in 10 patients. A treatment break was observed in 26 patients, whereas irradiation was prolonged more than 1 week in 11 patients. Logistic regression analysis showed the dysphagia score during the treatment course and the chest roentgenography pattern following symptomatic aspiration pneumonia were found to independently influence the outcome. Aspiration pneumonia occurring during chemoradiotherapy for head and neck cancer has a detrimental effect on the treatment outcome. Intensive medical care is essential for this group of patients with a dysphagia score of 3 during treatment and an unfavourable chest film pattern.

This study used radiomics image analysis to examine the differences of texture feature values extracted from oropharyngeal and hypopharyngeal cancer positron emission tomography (PET) images on various tumor segmentations, and finds the proper and stable feature groups. A total of 80 oropharyngeal and hypopharyngeal cancer cases were retrospectively recruited. Radiomics method was applied to the PET image for the 80 oropharyngeal and hypopharyngeal cancer cases to extract texture features from various defined metabolic volumes. Kruskal-Wallis one-way analysis of variance method was used to test whether feature value difference exists between groups, which were grouped by stage, response to treatment, and recurrence. If there was a significant difference, the corresponding feature cutoff value was applied to the Kaplan–Meier estimator to estimate the survival functions. For the various defined metabolic volumes, there were 16 features that had significant differences between early (T1, T2) and late tumor stages (T3, T4). Five images and 2 textural features were found to be able to predict the tumor response and recurrence, respectively, with the areas under the receiver operating characteristic curves reaching 0.7. The histogram entropy was found to be a good predictor of overall survival (OS) and primary relapse-free survival (PRFS) of oropharyngeal and hypopharyngeal cancer patients. Textural features from PET images provide predictive and prognostic information in tumor staging, tumor response, recurrence, and have the potential to be a prognosticator for OS and PRFS in oropharyngeal and hypopharyngeal cancer.

Our findings suggest that FDG-PET shows a similar sensitivity and a better accuracy than bone scan for detecting bone metastases in patients with breast cancer.

Background: Phase 3 studies suggest that induction chemotherapy (ICT) of cisplatin and 5-fluorouracil plus docetaxel (TPF) is effective but toxic for patients with squamous-cell carcinoma of the head and neck (SCCHN). Dose-dense chemotherapy may yield favorable outcomes compared with standard-dose chemotherapy, yet the optimal induction regimen remains undefined. We assessed the efficacy and tolerability of biweekly dose-dense TPF ICT in patients with SCCHN. Methods: In this prospective phase II study, We enrolled patients with stage III/IV (AJCC 7th edition) unresectable squamous cell carcinoma of head and neck cancer. Patients received dose-dense TPF (ddTPF) with cisplatin and docetaxel 50 mg/m2 on day 1, leucovorin 250 mg/m2 on day1, followed by 48-h continuous infusion of 2500 mg/ m2 of 5-fluorouracil on day 1 and 2, every 2 weeks for 6 cycles followed by radiotherapy. The primary endpoint was the response rate (RR) after ICT. Results: Fifty-eight patients were enrolled from June 2014 to September 2015. Overall RR after ICT was 89.6% [complete response (CR), 31%; partial response (PR), 58.6%]. Grade 3/4 neutropenia, mucositis, and diarrhea incidences were 25.9, 1.7, and 1.7%, respectively. 94.8% of patients completed all treatment courses of ICT without dose reduction. The 3-year overall survival (OS) was 54.3% (95%CI: 39.7 to 66.8%) and progression-free survival (PFS) was 34.3% (95%CI: 22.0 to 46.9%). Multivariate analysis showed that CR after ICT is an independent prognostic factor for OS and PFS. Conclusions: Six cycles of ddTPF is an active, well-tolerated induction regimen for patients with SCCHN. The presence of CR after ICT predicted long-term survival.
