OBJECTIVE:
This study aimed to evaluate the risk factors of radiation-induced caries by using a multiple linear regression equation and to provide the basis for the effective prevention of radioactive caries.
METHODS:
A total of 166 patients with head and neck cancer who underwent radiotherapy were selected as subjects. The number of decayed, missing or filled surfaces were recorded. Questionnaire contents included age, sex, radiation dose, and radiotherapy techniques. Multiple stepwise regression analyses were performed to identify the risk factors of radiation-induced caries.
RESULTS:
Multiple stepwise regression analyses indicated that the main risk factors of radiation-induced caries were plaque index, radiotherapy techniques, time after radiotherapy, and radiotherapy dose.
CONCLUSIONS
The awareness of dental care and caries treatment should be improved to reduce the occurrence of radiation-induced caries in patients with head and neck cancer. In addition, intensity modulated radiation therapy should be employed to decrease the radiation exposure dose received by teeth.

OBJECTIVE:
To sum up the experiences of diagnosis, treatment and medical evaluation of head and neck tumors in aircrew.
METHOD:
Sixty-seven cases of pilot patients with head and neck tumors in our hospital since September in 1979 to July in 2009 were retrospective analyzed in the study.
RESULT:
Among 44 aircrew with benign head and neck tumors there were 37 cases continued their flying jobs and 7 cases were permanently grounded; whereas in 23 aircrew with malignant tumors there were 6 cases qualified for flight and 17 patients unqualified.
CONCLUSION
Benign or malignant of the head and neck neoplasm in the pilots are not the exclusive basis for their medical assessment. Tumor nature, location, efficacy of treatment and the impact on the function of their body should be considered as making the flight medical evaluation for the aircrew with head and neck tumors. Early diagnosis and treatment of head and neck tumors in aircrew are very important for reducing the rate of grounded.

As the patients population ages, cancer screening increases, and cancer treatments improve, millions more head and neck carcinoma (HNC) patients will be classified as cancer survivors in the future. Change in epidemiology with human papillomavirus related HNC leads to a number of young treated patients. After treatment for HNC intensive surveillance, including ear, nose and throat (ENT) endoscopy, imaging, and serology, confers a survival benefit that became less evident in unresectable recurrence. We performed a comprehensive revision of literature and analyzed the experience of our centre. We revised publications on this topic and added data derived from the interdisciplinary work of experts within medical oncology, ENT, and radiation oncology scientific societies. We retrospectively collected local and distant recurrence of chemoradiation treated patients at Santa Croce and Carle University Hospital. A HNC follow-up program is not already codified and worldwide accepted. There is a need of scheduled follow-up. We suggest adopting a standardized follow-up guideline, although a multidisciplinary approach is frequently requested to tailor surveillance program and treatment on each patient.

PURPOSE: The purpose of this study was to compare the survival of patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) undergoing concurrent chemoradiotherapy (CRT) alone with that of patients undergoing induction chemotherapy (IC) using docetaxel, cisplatin, and 5-fluorouracil (TPF) followed by CRT. MATERIALS AND METHODS: A search of the PubMed, EMBASE, and Cochrane Library databases was performed in April 2015 and abstracts from the American Society of Clinical Oncology meetings (2008-2014) were reviewed. Summaries of the results were pooled using a fixed-effect model, and the risk of bias was evaluated using the Cochrane tool. RESULTS: A total of six relevant trials comprising 1,280 patients were identified. There was no statistically significant overall survival (OS) advantage for TPF prior to CRT (TPF/CRT) over CRT alone (hazard ratio [HR] 0.92; 95% confidence interval [CI], 0.79 to 1.09; p=0.339). Progression-free survival (PFS) was significantly longer in the TPF/CRT arms (HR, 0.82; 95% CI, 0.70 to 0.95; p=0.009). Patients with non-oropharyngeal LA-HNSCC obtained the greatest OS and PFS benefits from TPF (HR, 0.68; 95% CI, 0.47 to 0.99; p=0.043 and HR, 0.67; 95% CI, 0.48 to 0.94; p=0.022, respectively). The complete response rate was significantly increased (risk ratio [RR], 1.34; 95% CI, 1.14 to 1.56; p < 0.001), and the distant metastasis rate tended to decrease (RR, 0.65; 95% CI, 0.40 to 1.04; p=0.071) in the TPF/CRT arms. CONCLUSION: IC with TPF followed by CRT is not superior to CRT alone for OS. However, PFS and the complete response rate were significantly improved in the TPF/CRT arms. TPF/CRT for patients with nonoropharyngeal LA-HNSCC provided clear survival advantages.

High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

INTRODUCTIONNon-melanoma skin cancer is one of the commonest cancers in Singapore and worldwide. The aim of our study was to evaluate the demographic and clinicopathological patterns of squamous cell carcinoma (SCC) and Bowen's disease (BD) of the skin, in order to better understand the characteristics of these tumours in our population.
MATERIALS AND METHODSHistologically proven cases of SCC and BD seen at our centre between 2002 and 2003 were retrospectively analysed according to age, sex, race, predisposing factors such as immunosuppression and ultraviolet therapy, site and size of tumour, histological differentiation and subtype, and treatment method.
RESULTSA total of 161 patients were studied--81 with SCC, 68 with BD, and 12 with both tumours. There were 199 tumours in total--105 SCC and 94 BD. For both SCC and BD, males outnumbered females (ratio of 2.4:1 and 1.5:1 respectively); patient age averaged 72.9 years and 66.8 years respectively; and Chinese were the majority race. The mean duration to presentation was 21.2 months for SCC compared with 39.9 months for BD, and common symptoms were itch, pain and bleeding for both. The mean tumour size was 19.0 mm and 18.5 mm, and the commonest site was the head and neck for both.
CONCLUSIONSSCC and BD show rather similar patient characteristics, with a predominance among males, having a predilection for the head and neck region, and with a tendency towards slow growth. As incidences increase worldwide, it is important for healthcare providers to be adept at recognising and managing nonmelanoma skin cancers.

9.International collaborations preparing for a cancer "moon shot": a summary of the Sino-US Symposium on Head and Neck Cancer.
Chinese Journal of Cancer 2012;31(3):121-125
Oncologists and scientists in the field of head and neck cancer exchanged their research findings and clinical experiences in the Sino-USA Symposium on Head and Neck Cancer, which was held January 6-7, 2012 in Guangzhou, China. The symposium was jointly organized by Sun Yat-sen University Cancer Center (SYSUCC) and the University of Texas MD Anderson Cancer Center (MDACC). The Guangdong Provincial Anti-Cancer Association and the Chinese Journal of Cancer also helped in organizing the conference. Speakers were from China (SYSUCC, the Chinese University of Hong Kong, Tianjin Medical University Cancer Institute and Hospital, and Fudan University Shanghai Cancer Center) and the United States (MDACC). The presentations covered most kinds of head and neck cancers and included both basic and clinical research progress. In particular, NPC was discussed in depth. The symposium explored the reality that cancer is complex and numerous questions remain to be answered, even though there has already been an enormous effort into research. International exchanges of experience and in-depth cooperation are definitely needed to improve our capability of caring for cancer patients. In this article, we provide highlights of the presentations.

Objective: To investigate the safety and efficacy of enhanced recovery after surgery (ERAS) in the clinical management of hypopharyngeal squamous cell carcinoma (HSCC). Methods: In this retrospective study, a total of 168 patients with pyriform sinus carcinoma in Qilu Hospital of Shandong University from January 2015 to January 2019 were divided into two groups, based on the different perioperative interventions that patients received, i.e. the ERAS group (n=64) and the conventional group (n=104), including 164 males and 4 females, whose ages ranged from 42 to 84 years old. The difference between two groups in the operative time, postoperative nutritional status, incidences of postoperative complications and postoperative hospitalization time were compared using the student's t test, Chi-squared test or Fisher's exact test. Results: Compared with the conventional group, patients in the ERAS group had significantly shorter operative time [(166.8±58.2) min vs. (183.3±39.9) min,t=-2.72, P=0.031], higher levels of postoperative serum albumin [(38.3±4.2) μmol/L vs. (36.6±3.3) μmol/L, t=2.73, P=0.007] and more body weight [(65.4±9.4) kg vs. (62.1±9.4) kg, t=2.22, P=0.028], lower incidences of postoperative subcutaneous infection [7.8% (5/64) vs. 20.2% (21/104), χ²=4.64, P=0.03] and severe pneumonia [4.7% (3/64) vs. 15.4% (16/104), χ²=4.52, P=0.03], and shorter postoperative hospitalization time [(16.5±3.9) d vs. (18.2±4.3) d, t=-2.65, P<0.05]. Conclusion: ERAS is effective and safe in the surgical management of HSCC, with benefits in reducing the operative stress via saving operation time, shortening the hospitalization time, ameliorating nutritional status and decreasing the incidences of complications.
