  • Background: Recurrent nasopharyngeal carcinoma (NPC) after previous radiotherapy is challenging. There is no standard approach for salvage treatment. Here we present toxicity and treatment results for recurrent NFC patients who underwent fractionated stereotactic radiotherapy (FSRT) as second line radiotherapy (RT). Materials and Methods: Between April 2009 and July 2012, 24 patients, with a male to female ratio of 3:1, were treated with CykerKnife$^{(R)}$ FSRT for recurrent NFC in our institution. Seven out of 24 patients had metastatic recurrent disease. Median age was 53 years (range, 20-70 years). Initial RT dose was 70Gy. The time period between initial RT and FSRT was a median of 33.2 months. The median prescription dose for FSRT was 30Gy (range, 24-30 Gy) in a median of 5 fractions (range, 4-6). Results: The median follow-up for all patients was 19.5 months (IQR: 12.2.-29.2 months). The locoregional control; progression free survival and overall survival (OS) rates for 1-, 2- and 3-year were 64%, 38%, 21%; 60%, 30%, 17% and 83%, 43%, 31%, respectively. Median OS for the entire cohort was 22 months (95% CI: 16.5-27.5). On multivariate analysis recurrent tumor stage was the only prognostic factor for OS (p=0.004). One patient exhibited grade III temporal lobe necrosis. One died because of grade IV mucositis and overlapping infection. Conclusions: The treatment of recurrent NPC is controversial. Fractionated stereotactic radiotherapy is promising. However, the published trials are heterogeneous with respect to the selection criteria and treatment details. Prospective studies with long term follow-up data are warranted.

  • Objective : We retrospectively evaluated the efficacy of Gamma Knife radiosurgery (GKS) for recurrent nasopharyngeal carcinoma (NPC) in patients who previously underwent radiotherapy, and analyzed the treatment outcomes over 14 years. Methods : Ten patients with recurrent NPC who had previously received radiotherapy underwent stereotactic radiosurgery using a Gamma Knife® (Elekta Inc, Atlanta, GA, USA) between 2005 and 2018. The median target volume was 8.2 ㎤ (range, 1.7-17.8), and the median radiation dose to the target was 18 Gy (range, 12-30). The median follow-up period was 18 months (range, 6-76 months). Overall and local failure-free survival rates were determined using the Kaplan-Meier method. Results : The NPCs recurred at the primary cancer site in seven patients (70%), as distant brain metastasis in two (20%), and as an extension into brain in one (10%). The recurrent tumors in seven of the 10 patients (70%) were found on the routine follow-up imaging studies. Two patients presented with headache and one with facial pain. Local failure after GKS occurred in five patients (50%) : two of whom died eight and 6 months after GKS, respectively. No adverse radiation effects were noted after GKS. The 1- and 3-year overall survival rates after GKS were 90% and 77%, respectively. The local failure-free survival rates at 6 months, 1 year, and 3 years after GKS were 80%, 48%, and 32%, respectively. The median interval from GKS to local failure was 8 months (range, 6-12). Univariate analysis revealed that using co-registration with positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) was associated with a lower local failure rate of recurrent NPC (p=0.027). Conclusion : GKS is an acceptable salvage treatment option for patients with recurrent NPC who previously received radiation therapy. PET-CT and MRI co-registration for dose planning can help achieve local control of recurrent NPC.

  • Background and Objectives : The objective of this study was to investigate clinical factors associated with recurrence of nasopharyngeal carcinoma(NPC). Materials and Methods : We performed a retrospective review of 112 diagnosed as nasopharyngeal carcinoma, treated concurrent chemo-radiotherapy(CCRT) and had complete response from March 1, 1995, to March 31, 2012. Results : Of the recurrent NPC patients, patients received 2nd line chemotherapy had more recurrence within 2 years(p=0.010). Especially, patients received 2nd line chemotherapy longer than 4 months tend to have recurrence early(p=0.035). Other factors are not different between recurrent and non-recurrent NPC patients. Conclusion : The presence and the duration of 2nd line chemotherapy are associated with early recurrence.

  • Background: We assessed the efficacy and toxicity of ifosfamide and doxorubicin combination chemotherapy (CT) regimen retrospectively in Turkish patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) previously treated with platinum-based chemotherapy. Methods: A total of thirty patients who had received cisplatin based chemotherapy/chemoradiotherapy as a primary treatment received ifosfamide 2500 $mg/m^2$ days 1-3, mesna 2500 $mg/m^2$ days 1-3, doxorubicin 60 mg/m2 day 1 (IMA), repeated every 21 days. Eligible patients had ECOG PS< 2, measurable recurrent or metastatic disease, with adequate renal, hepatic and hematologic functions. Results: Median age was 47 (min-max; 17-60). Twenty six (86.7 %) were male. Median cycles of chemotherapy for each patient were 2 (range:1-6). Twenty patients were evaluable for toxicity and response. No patient achieved complete response, with nine partial responses for a response rate of 30.0% in evaluable patients. Stable disease, and disease progression were observed in five (16.7%) and six (20.0%) patients, respectively. Clinical benefit was 46.7%. Median time to progression was 4.0 months. Six patients had neutropenic fever after IMA regimen and there were one treatment-related death due to tumor lysis syndrome in first cycle of the CT. No cardiotoxicity was observed after CT and treatments were generally well tolerated. Conclusion: Ifosfomide and doxorubicin combination is an effective regimen for patients with recurrent and metastatic NPC. For NPC patients demonstrating failure of cisplatin based regimens, this CT combination may be considered as salvage therapy.

  • Background: To evaluate the treatment outcome and major late complications of all patients with recurrent nasopharyngeal carcinoma (NPC) treated with intracavitary brachytherapy (ICBT) in Hospital Kuala Lumpur. Materials and Methods: This retrospective study was conducted at the Department of Radiotherapy and Oncology, Hospital Kuala Lumpur, Malaysia. All patients with histologically confirmed recurrent NPC in the absence of distant metastasis treated in the period 1997-2010 were included in this study. These patients were treated with ICBT alone or in combination with external beam radiotherapy (EBRT). Treatment outcomes measured were local recurrence free survival (LRFS), disease free survival (DFS) and overall survival (OS). Results: Thirty three patients were eligible for this study. The median age at recurrence was 56 years with a median time to initial local recurrence of 27 months. Majority of patients were staged as rT1-2 (94%) or rN0 (82%). The proportion of patients categorised as stage III-IV at first local recurrence was only 9%. Twenty one patients received a combination of ICBT and external beam radiotherapy while 12 patients were treated with ICBT alone. Median interval of recurrence post re-irradiation was 32 months (range: 4-110 months). The median LRFS, DFS and OS were 30 months, 29 months and 36 months respectively. The 5 year LRFS, DFS and OS were 44.7%, 38.8% and 28.1% respectively. The N stage at recurrence was found to be a significant prognostic factor for LRFS and DFS after multivariate analysis. Major late complications occurred in 34.9% of our patients. Conclusions: Our study shows ICBT was associated with a reasonable long term outcome in salvaging recurrent NPC although major complications remained a significant problem. The N stage at recurrence was a significant prognostic factor for both LRFS and DFS.

  • Background: To explore the independent prognostic factors for the recurrence/metastasis of patients with locoregionally advanced nasopharyngeal carcinoma (LANPC). Materials and Methods: A total of 604 patients initially diagnosed as LANPC by pathohistology in Fujian Provincial Cancer Hospital were selected to analyze the relationship between the clinical pathological patterns, therapeutic protocols and clinical stages with the recurrence/metastasis of LANPC. Results: The 1-, 3- and 5-year locoregionally recurrent rates of LANPC patients were 2.0%, 9.5% and 12.9% respectively, with average recurrent period being 78 months. Univariate analysis results indicated that clinical stages had certain influence on the recurrent period of LANPC patients. However, COX regression models showed that ages, genders and clinical stages were not the independent prognostic factors influencing the recurrence. The 1-, 3- and 5-year metastatic rates of LANPC patients were 6.6%, 17.5% and 18.8% respectively, with average metastatic period of 73 months. Univariate analysis results demonstrated that ages, N stages, clinical stages, locations of lymph node, retropharyngeal lymph node and extracapsular invasion of lymph node had certain influence on the metastatic period of LANPC patients. Additionally, further COX regression analysis results suggested that T stages, reduction protocols and extracapsular invasion of lymph node were the independent prognostic factors influencing the metastasis of patients with LANPC, in which T stages and extracapsular invasion of lymph node were the pestilent factors while reduction protocols the protective factor. Conclusions: Induction chemotherapy is beneficial to LANPC patients with initial treatment, and the metastatic rate decreases greatly after the application of reduction chemotherapy.

  • Nasopharyngeal carcinoma(NPC) is a disease whose primary initial treatment is radiation. Results of radiation therapy in early stage disease is promising; however, in stage IV disease, the best reported five-year survival is only about 30%. In patients with post-radiation recurrent disease, radiation controls only a small portion of patients, as well as being associated with significant radiation injury. In this paper we discuss the use of salvage treatment modalities for post-radiation recurrence. A retrospective chart review and analysis of salvage treatment results were performed for 39 patients with recurrent post-radiation NPC and positive cervical lymph nodes during the period beginning 1985 until 1995. Mean age of these patients was 52.3$\pm$10.37 years and male: female ratio was 1.8 : 1. Twenty patients were treated with salvage treatment, and ten patients were treated by salvage chemotherapy. A total of nine patients underwent surgical salvage treatment, including neck dissection(6), transnasal laser surgery and booster radiotherapy(2), and primary surgery(1). Salvage treatment were effective in reducing patients' pain in twenty patients (51.3%) and prolonging life in nine patients(23.1%); however, recurrence of disease within six months and/or residual disease by clinical or radiologic exam was noted in all patients receiving salvage radiotherapy, chemotherapy, laser surgery with radiotherapy, and primary site surgery. In the group undergoing salvage neck dissection, three patients(50%) were disease free for at least two years. Of the different modalities, radiotherapy was associated with the best quality of life while catastrophic salvage surgery resulting in insignificant prolongation of life was associated with the poorest quality of life. We conclude that salvage surgery is the optimal choice of treatment for regional recurrence such as nodal failure, however palliative salvage therapy could be preferred in other cases with recurrent post-radiation NPC.

  • Background: Palliative chemotherapy with cisplatin/5-fluorouracil (5FU) is the commonest regimen employed for metastatic and recurrent head and neck squamous cell carcinoma (SCCHN) and nasopharyngeal carcinoma (NPC). However, this regimen is cumbersome requiring 5 days of admission to hospital. Carboplatin/5FU may be an alternative regimen without compromising survival and response rates. This study aimed to compare the efficacy and toxicity of carboplatin/5FU regimen with the cisplatin/5FU regimen. Materials and Methods: This retrospective study looked at patients who had palliative chemotherapy with either cisplatin/5FU or carboplatin/5FU for metastatic and recurrent SCCHN and NPC. It included patients who were treated at UKMMC from $1^{st}$ January 2004 to $31^{st}$ December 2009 with either palliative IV cispaltin 75 $mg/m^2$ D1 only plus IV 5FU 750 $mg/m^2$ D1-5 infusion or IV Carboplatin AUC 5 D1 only plus IV 5FU 500 $mg/m^2$ D1-2 infusion plus IV 5FU 500 $mg/m^2$ D1-2 bolus. The specific objectives were to determine the efficacy of palliative chemotherapy in terms of overall response rate (ORR), median progression free survival (PFS) and median overall survival (OS) and to evaluate the toxicities of both regimens. Results: A total of 41 patients were eligible for this study. There were 17 in the cisplatin/5FU arm and 24 in the carboplatin/5FU arm. The ORR was 17.7 % for cisplatin/5FU arm and 37.5 % for carboplatin/5FU arm (p-value=0.304). The median PFS was 7 months for cisplatin/5FU and 9 months for carboplatin/5FU (p-value=1.015). The median OS was 10 months for cisplatin/5FU arm and 12 months for carboplatin/5FU arm (p-value=0.110). There were 6 treatment-related deaths (6/41=14.6%), four in the carboplatin/5FU arm (4/24=16.7%) and 2 in the cisplatin/5FU arm (2/17=11.8%). Grade 3 and 4 hematologic toxicity was also more common with carboplatin/5FU group, this difference being predominantly due to grade 3-4 granulocytopenia (41.6% vs. 0), grade 3-4 anemia (37.5% vs. 0) and grade 3-4 thrombocytopenia (16.6% vs. 0). Conclusions: Carboplatin/5FU is not inferior to cisplatin/5FU with regard to its efficacy. However, there was a high rate of treatment-related deaths with both regimens. A better alternative needs to be considered.

  • Herpes virus family is highly infectious to patients, their families and dentists. The diagnosis of herpes infection is based on the characteristic clinical appearance and the location of the lesions. Herpes Simplex Virus(HSV) usually acquired through direct contact with infected lesions or body fluids, and the prevalence of HSV infection increases progressively from childhood. Primary infections provoke herpetic gingivostomatis typically affects the tongue, lips, gingival, buccal mucosa and palate. Recurrent infections give rise to vesiculo-ulcerative lesions at vermilion border of lip(herpes labialis). In the form of chickenpox, Varicella Zoster Virus(VZV) usually is infected in childhood. VZV spreads in the affected primary afferent nerve to the skin and produces a vesicular rash and pain. Epstein-Barr Virus(EBV) infects B cells and cause infectious mononucleosis. Latent EBV infection has also been implicated in Burkitt lymphoma, nasopharyngeal carcinoma. Cytomegalovirus(CMV) is associated with immune-compromised patient such as organ transplantation and AIDS patients.
