  • Skull base osteoradionecrosis(ORN)is a rare complication of radiotherapy for nasopharyngeal carcinoma, but is one of the most severe and possibly fatal condition followed by radiotherapy. However, the treatment of skull base ORN has seldom been thoroughly described yet. Here we report a case of skull base ORN that was successfully treated with hyperbaric oxygen therapy(HBO). A 52-year-old man visited our department complaining of trismus and foul odor. He was diagnosed with nasopharyngeal cancer with multiple lymph node metastasis one year ago and underwent concurrent chemoradiotherapy. On the physical examination, mucopus and crusts with exposed necrotic bone was seen in the right nasopharynx. On the paranasal sinus magnetic resonance imaging, osteoradionecrosis which was extending from the right nasopharynx to the clivus, petrous apex, and cavernous sinus was noted. Nasopharynx biopsy resulted of ulcer with no malignant cells. HBO therapy was performed with debridement of nasopharynx for 3 months. There was no sign of recurrence or residual ORN 18 months after HBO therapy.

  • Objectives: To analyze underlying disease, fatality rate and the major causes of death of in-patients with malignant tumors in Sichuan Cancer Hospital. Methods: Clinical data of in-patients from 2002 to 2012 were retrospectively analyzed. Results: The top 10 tumors (82.0%of the total) of the malignant tumors of the in-patients were lung, cervical, esophagus, breast, colorectal, nasopharynx, liver and gastric cancers, lymphomas and ovarian cancers. The overall fatality rate was 2.7% during these eleven years, 3.4% and 2.0% for male and females, respectively with statistical significance for the difference (${\chi}^2$=164.737, P<0.001). The top 10 death causes were lung cancer, liver cancer, colorectal cancer, esophagus cancer, gastric cancer, lymphoma, breast cancer, pancreatic cancer, ovarian cancer and nasopharynx cancer. In-patients with pancreatic cancer had the highest fatality rate (9.6%). There were different ranks of death causes in different sex groups and age groups. Conclusion: Prevention and control work of cancer should be enhanced not only for cancers with high incidence such as lung cancer, esophageal cancer but also for the cancers which have low incidence but high fatality rate, such as pancreatic cancer and gallbladder cancer, which would help to improve the survival rate and quality of life of cancer patients in the future.

  • Concurrent chemoradiation therapy (CCRT) has played the most important and central role in the definitive therapy for the patients with locoregionally advanced stage nasopharynx cancer. The addition of induction chemotherapy (IC) or adjuvant chemotherapy (AC) to CCRT have been widely accepted with the rationale of improving distant control in the clinical practices. This review article investigated the role of IC and AC based on 11 recent meta-analysis publications, and found that the clinical benefits obtained by the additional IC or AC to CCRT, at the cost of the increased risks of more frequent and more severe side effects, seemed not big enough. More intervention is not always better, however, less seems frequently good enough. The author would speculate that 'less is more' and would advocate CCRT alone as the current standard.

  • Thirty nine cases of nasopharyngeal malignant tumor from 1981 to 1989 in Korea univeristy hospital were reviewed retrospectively. The results were as follows; 1) The most common initial symptom was neck mass(41.0%), and cranial nerve involvement was found in 6 cases. Lateral wall of the nasopharynx including $Rosenm\"{u}ller's$ fossa was the frequent predelection site(68.4%). 2) Histopathologically, squamous cell carcinoma was the most common and stage IV were 71.8%. 3) Thirty four cases were treated by radiation therapy alone and 5 cases were treated by combined modality(radiation therapy+chemotherapy). Overall 5 year survival rate was 28.2%(squamous cell carcinoma; 23.5%, undifferentiated carcinoma; 35.7%).

  • RTOG proposed a multivariate modelling system predicting the response of head and neck cancers to radiation therapy in 1984. The aim of this study was to veri(y whether PPC (Probaility of primary clearance calculated by a multivariate modelling system) had any correlation with the survival in the patients with carcinoma of the nasopharynx following radiation therapy Analysing 81 patients with carcinoma of the nasopharynx treated with radiotherapy between January 1, 1971 and December 31, 1983 at Yonsei University College of Medicine, Yonsei Cancer Center the actuarial 5 year survival rate was $36\%$ and median survival was 39 months. The survivals for Group 1 (27 who had more than $80\%$ of PPC), Group 2 (20 who had between 71 and $80\%$ of PPC), and Group 3 (29 who had less than $71\%$ of PPC) were $66\%$ (median survival months : more than 72), $27\%$ (31), and $4\%$ (12) respectively. There was a definite correlation between PPC and survival among the three groups.

  • Purpose : This study is to report experience with Fractionated Stereotactic Radiation Therapy (FSRT) for locally recurrent nasopharynx cancer after curative conventional radiation therapy. Materials and Methods : Three Patients with locally recurrent and symptomatic nasopharynx cancer were given FSRT as reirradiation method between the Period of September of 1995 and August of 1996 For two Patients, application of FSRT is their third radiation therapy directed to the nasopharynx. Two patients were given low dose chemotherapy as radiation sensitizer concurrently with FSRT Authors used 3-dimensional coordinate system by individually made, relocatable Gill-Thomas-Cosman (GTC) stereotactic frame and multiple non-coplanar arc therapy dose Planning was done using Xknife-3. Total of 45 Gy/18 fractions or 50 Gy/20 fractions were given. Results : Authors observed satisfactory symptomatic improvement and remarkable objective tumor size decrease by follow-up MR images taken 1 month Post-FSRT in ali three patients, while no neurologic side effect attributable to reirradiation was noticed. Two died at 7 and 9 months with loco-regional and distant seeding outside FSRT field, while one patient is living for 4 month. Conclusion Authors experienced satisfactory therapeutic effectiveness and safety of FSRT as reirradiatlon method for locally recurrent nasopharynx cancer Development of more effective systemic chemotherapeutic regimen is desired for distant metastasis

  • The actual burden of head and neck cancer in India is much greater than reflected through the existing literature and hence can be regarded as a 'tip of iceberg' situation. This has further been evident by the recent reports of 'Net-based Atlas of Cancer in India'. South-east Asia is likely to face sharp increases of over 75% in the number of cancer deaths in 2020 as compared to 2000. Since the percentage increase of Indian population has been nearly twice that of the world in last 15 years there is a likelihood of increase in cancer burden with the same proportion. The distribution of population based cancer registries is grossly uneven with certain important parts of the country being not represented at all and hence the current cancer burden is not reflected by registry data. However, the pathetic situation of health care system in major parts of the country as also emphasized by the World Bank, is not suitable to provide anywhere near accurate data on cancer burden. Head and neck cancer (including thyroid lesions) is third most common malignancy seen in both the sexes across the globe but is the commonest malignancy encountered in Indian males. Also oral cavity cancer is the most prevalent type amongst the males and one of the highest across the globe. This article reviews the latest global and national situation with an especial emphasis on head and neck cancer. Furthermore this review focuses on burden in different sub sites at national and global levels.

  • Background: Mean platelet volume (MPV) is a marker which has been investigated in many cancers but data for head and neck lesions are limited. We aimed to study the MPV levels in head and neck cancers as a diagnostic marker. Materials and Methods: A total of 96 head and neck cancer patients and 31 control patients who did not meet exclusion criteria were enrolled in the study. The cancer locations, the platelet and MPV levels at the first diagnosis time were collected. Results: The head and neck cancer location distribution between these patients was 2 (2.1%) buccal, 9 (9.4%) tongue, 6 (6.3) lip, 1 (1%) gingiva, 1 (1%) hypopharynx, 1 (1%) ear, 58 (60.4%) larynx, 2 (2.1%) maxilla, 2 (2.1%) nasal, 1 (1%) nasopharynx, 2 (2.1%) palatal, 3 (3.1%) primary unknown, 1 (1%) retromolar, 1 (1%) thyroid, 2 (2.1%) tonsil, and 4 (4.2%) salivary gland. MPV levels were significantly different between cancer and control group (p=0.002). The cut-off point for MPV predicting head and neck cancer is >10 fL (sensitivity=55.21, specificity=87.10). Conclusions: MPV level increase, a readily assessable parameter which does not bring extra costs can warn us regarding head and neck cancer risk.

  • Multiple primary cancer is defined as two or more malignant neoplasms in a single individual. The incidence of multiple primary cancer is likely to increase due to earlier and accurate diagnosis and prolonged life span. Above all, the incidence of quintuple primary malignant tumors is reportedly extremely rare. Herein, we present a case of 65-year-old who had quintuple primary cancers of the liver, rectum, nasopharynx, oropharynx and hypopharynx.
