Predictive markers, including total lesion glycolysis, for the response of lymph node(s) metastasis from head and neck squamous cell carcinoma treated by chemoradiotherapy.

BACKGROUND: Chemoradiotherapy (CRT) is used to treat cervical lymph node(s) metastatic head and neck cancer patients. Evaluation and treatment of lymph node(s) after CRT is important to improve the prognosis. METHODS: Prior to CRT, we determined the TNM stage by visual and imaging examinations. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were calculated from the results of fluorodeoxyglucose-positron emission tomography (FDG-PET). After CRT, the patients were divided in two groups-complete response (CR) and non-CR-and their responses were compared with the clinical characteristics. RESULTS: T4, N2b, N2c and TLG2.5 ≥ 18.8 were statistically significant predictive indices before CRT. The odds ratio, 95 % confidence interval and p value were, respectively-T4: 2.73, 1.15-6.51, 0.0230; N2b: 6.96, 1.50-32.3, 0.0132; N2c: 11.80, 2.37-58.50, 0.00258; and TLG2.5 ≥ 18.8: 6.25, 2.17-18.00, 0.000672. CONCLUSIONS: TLG was found to be a good predictive factor for metastatic lymph node(s) prior to CRT treatment. After CRT treatment, FDG-PET was found to be highly specific and useful for negative screening.

Treatment results and prognostic factors for advanced squamous cell carcinoma of the head and neck treated with salvage surgery after concurrent chemoradiotherapy.

BACKGROUND: For primary organ preservation, concurrent chemoradiotherapy (CCRT) is performed for advanced squamous cell carcinoma of the head and neck (SCCHN). In this organ-preservation setting with CCRT, surgery is reserved as a salvage treatment in cases of locoregional failure after CCRT. The purpose of the study was to review our experience with salvage surgery after CCRT for patients with SCCHN and to evaluate the effectiveness and prognostic factors affecting survival. METHODS: The records of patients with stage II-IVB SCC of the larynx, oropharynx, or hypopharynx treated with salvage surgery after CCRT between 1998 and 2012 were reviewed. RESULTS: A total of 645 patients with previously untreated, resectable SCC of the larynx, oropharynx, or hypopharynx received CCRT. Salvage surgery was performed for 78 of 225 patients with residual or recurrent tumors. The 5-year overall survival (OS) and disease-specific survival rates for patients who received salvage surgery were 61.0 and 65.5 %, respectively. Stage IV, poorly differentiated, synchronous double cancer, and surgical complications were significant predictors of unfavorable OS on multivariate analysis. Postoperative complications were observed in 30 patients (38.5 %). CONCLUSIONS: Salvage surgery is the best therapeutic option for failure after CCRT for SCCHN because of its good survival rate, although a high surgical complication rate is seen. Patients with initial stage IV tumors, poorly differentiated SCC, or synchronous double cancer are considered for further adjuvant treatment.

Imaging strategy for response evaluation to chemoradiotherapy of the nodal disease in patients with head and neck squamous cell carcinoma.

BACKGROUND: Definitive chemoradiotherapy (CRT) is used to treat lymph node metastatic head and neck cancer patients. Regional control of the neck disease is important to improve the prognosis, and the accuracy of the method used to evaluate the metastatic lymph node(s) after CRT is crucial to the decision-making process for any following salvage surgery. METHODS: Patients undergoing CRT were divided in two groups of patients of those showing complete clinical response (CR) and those showing clinical non-response (non-CR), as assessed by computed tomography (CT) and/or magnetic resonance imaging (MRI), ultrasonography, fluorodeoxyglucose-positron emission tomography (FDG-PET), and fine needle aspiration cytology. The responses (CR vs. non-CR) were compared with the actual clinical outcomes. For the interim analysis, the study period was broken down into two periods, namely, the exploratory phase (patients treated between January 2002 and April 2012) and the validating phase (patients treated between May 2012 and January 2014). RESULTS: The sensitivity, specificity, and accuracy were as follows: CT and/or MRI, 66.7, 73.8, and 72.8 %, respectively, in the exploratory phase; ultrasonography, 91.7, 70.6, and 73.4 %, respectively, in the exploratory phase and 80.0, 82.8, and 82.4 %, respectively, in the validating phase; FDG-PET, 50.0, 97.5, and 91.3 %, respectively, in the exploratory phase and 60.0, 100, and 94.1 %, respectively, in the validating phase; cytology, 68.4, 95.9, and 90.3 %, respectively, in the exploratory phase and 66.7, 100, and 85.7 %, respectively, in the validating phase. CONCLUSIONS: Based on our results, CT and/or MRI appear to be inadequate methods for the evaluation of the response of lymph node(s) to CRT. In contrast, ultrasonography appears to be a highly sensitive and useful tool for positive screening at 6-8 weeks after CRT, and FDG-PET appears to be a highly specific and useful tool for negative screening at 8-12 weeks after CRT.

Phase II study of concurrent chemoradiotherapy with S-1 in patients with stage II (T2N0M0) squamous cell carcinoma of the Pharynx or Larynx.

OBJECTIVE: The goals of treatment for head and neck cancer are cure and organ-function preservation. For organ preservation, primary treatment via radiotherapy alone is thought to be insufficient for Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx. The objective of the present study was to investigate the efficacy and safety of concurrent chemoradiotherapy with S-1 for patients with Stage II squamous cell carcinoma of the pharynx or larynx for primary organ preservation. METHODS: Previously untreated patients with Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx received three courses of S-1 (40 or 50 mg twice a day; 2 weeks of administration followed by 1 week of rest every 3 weeks) during conventional radiotherapy (a single daily fraction of 1.8 Gy) to a total dose of 70.2 Gy. The primary endpoint was the local control rate at 3 years. RESULTS: From August 2009 to October 2012, 37 patients were evaluated for the study. The overall response rate was 100%. The 3-year local control rate was 89.0% (95% confidence interval, 78.9-99.2%), and the 3-year overall survival rate was 97.2% (95% confidence interval, 91.8-100%). Mucositis and dermatitis in the radiation field were the most common acute adverse events observed. The rates of Grade 3 mucositis and dermatitis were 27 and 35%, respectively. No patients experienced Grade 4 acute adverse events. The treatment completion rate was 89.2%. CONCLUSION: Concurrent chemoradiotherapy with S-1 was safe and effective in improving local control for Stage II squamous cell carcinoma of the pharynx or larynx.

Concurrent chemoradiotherapy with docetaxel, cisplatin and 5-fluorouracil (TPF) in patients with locally advanced squamous cell carcinoma of the head and neck.

OBJECTIVE: Compared with radiotherapy alone, concurrent chemoradiotherapy significantly improves survival rates for patients with squamous cell carcinoma of the head and neck. The aim of this study was to retrospectively evaluate the efficacy, toxicity and long-term prognosis of concurrent chemoradiotherapy with docetaxel, cisplatin and 5-fluorouracil chemotherapy. METHODS: A total of 140 patients were enrolled and evaluated. Patients were received two cycles of docetaxel, cisplatin and 5-fluorouracil chemotherapy (docetaxel [50 mg/m(2): Day 1], cisplatin [60 mg/m(2): Day 4] and continuous 5-fluorouracil [600 mg/m(2)/day: Days 1-5]) during definitive radiotherapy. RESULTS: The overall response rate was 97.1%. The 3 and 5-year overall survival rates were 83.3 and 79.2%, respectively. The 3 and 5-year disease-specific survival rates were 84.2 and 80.0%, respectively. Among patients with laryngeal or hypopharyngeal carcinoma, the 5-year laryngectomy-free survival rate was 64.9%. CONCLUSIONS: Concurrent chemoradiotherapy with docetaxel, cisplatin and 5-fluorouracil showed excellent survival and organ preservation rates for the patients with locally advanced squamous cell carcinoma of the head and neck.

[A study of surgical procedures for inverted papilloma in the nasal cavity and paranasal sinuses].

Inverted papilloma, although benign, recurs frequently and may become malignant, making definitive initial resection extremely important. We evaluated surgical procedures for recurrence and sites, with special reference to management of the orbital plate of the ethmoid and lacrimal bones, in 24 patients (32 cases) with inverted papilloma of the nasal cavity and paranasal sinuses undergoing surgical resection from 2000. Nine of the 32 showed recurrence, all around the ethmoid orbital plate. Up to 2002, recurrence was noted in 7 of 17 cases (41%), so we changed surgical selection criteria. Since 2003, we have conducted partial and combined excision of the orbital plate of the ethmoid and lacrimal bones (extended operation of the extranasal ethmoid and frontal sinuses) in cases in which tumors adhered to the orbital plate, noting recurrences in only 2 of 15 cases (13%). A number of reports advocate endoscopic sinus surgery to minimize invasiveness for inverted papilloma, but partial and combined excision of the orbital plate is indispensable, in progressive inverted papilloma cases to reduce recurrent.

Postoperative Bio-Chemoradiotherapy Using Cetuximab and Docetaxel in Patients With Cis-Platinum-Intolerant Core High-Risk Head and Neck Cancer: Protocol of a Phase 2 Nonrandomized Clinical Trial.

BACKGROUND: We confirmed the safety of postoperative bio-chemoradiotherapy using cetuximab and docetaxel in a small number of patients with cis-platinum-intolerant core high-risk head and neck cancer. OBJECTIVE: To assess treatment efficacy, we planned a phase 2 study of postoperative bio-chemoradiotherapy for patients with cis-platinum-intolerant core high-risk head and neck cancer and will compare the results to those of previously collected radiotherapy data. METHODS: Patients who underwent definitive surgery for oral cavity, laryngeal, oropharyngeal, or hypopharyngeal advanced cancer, whose postoperative pathological results indicated core high risk for recurrence (eg, positive margin in the primary site or extranodal extension) and who were cis-platinum-intolerant, will undergo postoperative bio-chemoradiotherapy. The primary end point is 2-year disease-free survival. RESULTS: The expected 2-year disease-free survival is set at 55%, and the calculated sample size is 35 patients, according to a statistical analysis based on previous reports. CONCLUSIONS: This treatment method is expected to improve the survival rate of patients with severe head and neck cancer.

Efficacy and safety of postoperative bio-chemoradiotherapy using cetuximab and docetaxel for high-risk head and neck cancer patients in Japan.

PURPOSE: To confirm the efficacy and safety of cetuximab and docetaxel in postoperative radiotherapy for high-risk head and neck cancer patients who cannot to be administered high-dose cisplatin. PATIENTS AND METHODS: The eligibility criteria required stage III-IVB head and neck cancer patients who had undergone total resection, and for whom pathological evaluation revealed positive or close margins in the primary site and/or extracapsular nodal extension and/or two or more nodal metastases. In each case, the patients general condition prevented the use of high-dose cisplatin. Instead, they received cetuximab and docetaxel every week during a 66.6 Gy course of postoperative radiotherapy. RESULTS: Eleven patients were enrolled; the median follow-up period was 22 months, and the 1- and 2-year disease free survival rates were 91 and 55%, respectively. Grade 3 adverse events included oral mucositis, radiation dermatitis, reduced white blood cell and neutrophil counts, lung infection, aspiration, and hyponatremia; however, no grade 4 adverse events were observed. CONCLUSION: Administration of cetuximab and docetaxel during postoperative radiotherapy for high-risk poor condition head and neck cancer patients in poor general condition was both feasible and tolerable. With the safety of this treatment confirmed, we propose a phase trail to further clarify the efficacy of cetuximab and docetaxel use for high-risk cisplatin-intolerant patients.

Surgery-based versus radiation-based treatment strategy for a high metabolic volume laryngeal cancer.

OBJECTIVE/HYPOTHESIS: We previously reported that the metabolic tumor volume (MTV) of a primary tumor was an independent prognostic factor for survival in laryngeal carcinoma treated by radiotherapy (RT)-based protocol. The purpose of this study was to evaluate the difference in survival outcomes between surgery-based and RT-based treatment in patients with a MTV laryngeal cancer. STUDY DESIGN: An individual retrospective cohort study. METHODS: We reviewed the records of 63 patients with laryngeal cancer showing a primary tumor with a high MTV value (≥ 4.9 mL). The patients were separated into two groups by primary treatment strategy: 22 patients were included in the surgery group, and 41 patients were included in the RT group. Clinical factors and treatment modalities were analyzed for their association with survival. RESULTS: Multivariate analysis, including age, sex, subsite, T classification, nodal metastasis, and treatment modality, showed that the subsite (hazard ratio [HR] 2.55, P = 0.043) and treatment modality (HR 3.98, P = 0.019) were independent predictors for survival. The Kaplan-Meier curves for 2-year relapse-free survival rates and overall survival rates for patients in the surgery and RT groups were 74.2% versus 38.8% (P = 0.025) and 80.1% versus 66.7% (P = 0.078). CONCLUSIONS: Patients with a high metabolic volume laryngeal cancer treated by a surgery-based protocol showed better relapse-free survival and overall survival than did those undergoing RT-based treatment. Pretreatment MTV assessment could be useful in planning the treatment strategy for patients with a laryngeal cancer. LEVEL OF EVIDENCE: 2b. Laryngoscope, 127:862-867, 2017.

Actinomycosis arising from the nasal cavity, with rare fatal progression.

Actinomycosis is a common treatable disease caused by Actinomyces, and generally has a good prognosis. However, we report a fatal case of actinomycosis of the nasal cavity. A 54-year-old man, reporting of left nasal obstruction, swelling and sharp pain around the root of the nose, was referred to our hospital. Histopathological examinations led to a definitive diagnosis of actinomycosis, and oral antibiotics were administered in an outpatient setting. However, the patient discontinued follow-up at the outpatient clinic because of the adverse effects of intravenous delivery, and poor compliance with oral antibiotic therapy led to him receiving a less than adequate dose. Thus, in the absence of sufficient antibiotic treatment, necrosis gradually progressed in the lesion, and the patient died of multiple organ failure and disseminated intravascular coagulation caused by local infection.

Prognostic significance of metabolic tumor volume in patients with piriform sinus carcinoma treated by radiotherapy with or without concurrent chemotherapy.

BACKGROUND: The purpose of this study was to elucidate the prognostic significance of the pretreatment metabolic tumor volume (MTV) in patients with piriform sinus carcinoma treated by radiation-based therapy. METHODS: This retrospective study included 100 patients with piriform sinus carcinomas who had received treatment by radiation-based therapy. The MTV values were obtained from pretreatment positron emission tomography (PET). The association between clinical factors, including the MTV, and survival was analyzed. RESULTS: Kaplan-Meier estimates revealed the 5-year disease-free survival (DFS) rates were significantly poorer for patients with a high MTV compared to those with a low MTV. In the multivariate analysis, MTV (p < .001), nodal metastasis (p = .011), and applied chemotherapy regimen (p = .004) were found to be independent prognostic factors for DFS. CONCLUSION: The locoregional MTV is a prognostic factor for DFS in patients with piriform sinus carcinoma treated by radiation-based therapy. © 2016 Wiley Periodicals, Inc.

Phase II trial of concurrent bio-chemoradiotherapy using docetaxel, cisplatin, and cetuximab for locally advanced head and neck squamous cell carcinoma.

PURPOSE: Although locally advanced head and neck squamous cell carcinoma (HNSCC) can be effectively treated using chemoradiotherapy (CRT) with docetaxel (DTX), and cisplatin (CDDP) plus 5-fluorouracil (TPF-CRT), severe adverse events (especially neutropenia) can limit treatment adherence. Therefore, we evaluated the safety and efficacy of a new chemotherapy regimen that consisted of DTX and CDDP plus cetuximab (Cmab) with concurrent radiotherapy. METHODS: Bio-chemoradiotherapy (B-CRT) using DTX, CDDP, and Cmab was administrated to patients with locally advanced HNSCC, and its safety and efficacy were evaluated. RESULTS: Interim analysis of nine patients revealed severe neutropenia in five patients (56 %) and leukopenia in seven patients (78 %); hence, the study was terminated. One patient experienced disease-free survival using only B-CRT. CONCLUSIONS: Neutropenia was equally severe for B-CRT, compared to TPF-CRT. Based on the limited sample size, it is impossible to conclude that B-CRT has non-inferior efficacy, compared to TPF-CRT.

Differential expression of periostin in the nasal polyp may represent distinct histological features of chronic rhinosinusitis.

OBJECTIVE: Chronic rhinosinusitis (CRS) is thought to be a multifactorial disease, and it is classified into a number of subtypes according to clinicohistological features. Periostin, a 90-kDa secreted protein, was reported to exist in nasal polyps (NPs) associated with CRS. We compared the expression of periostin with the degree of eosinophilic infiltration as well as tissue remodeling. MATERIALS AND METHODS: Tissue samples were collected from 28 patients of CRS with NPs, and clinicohistological features were evaluated. The pattern of periostin expression was assessed immunohistochemically. RESULT: Two patterns of periostin expression was observed in nasal polyps: "diffuse type", in which periostin was expressed throughout the lamina propria starting just below the basement membrane, and "superficial type", in which the protein was detected only in the subepithelial layers between the basement membrane and the nasal gland. The average infiltrated eosinophil count in the diffuse type was significantly higher than that in the superficial type (diffuse type 360.5±393.0 vs. superficial type 8.46±13.81, p=0.001). Tissue remodeling was observed in 17 (85.0%) of the 20 diffuse-type nasal polyps, but only in one (12.5%) of the eight superficial-type nasal polyps (p<0.001). CONCLUSION: At least two distinct patterns of periostin expression were observed in the nasal polyps associated with CRS in accordance with the heterogeneous mechanisms underlying the pathogenesis of CRS with NPs.

Concurrent Chemoradiotherapy with Docetaxel, Cisplatin and 5-Fluorouracil (TPF) in Patients with Nasopharyngeal Carcinoma.

BACKGROUND/AIM: Several randomized trials have shown that concurrent chemoradiotherapy (CCRT) either with or without adjuvant chemotherapy is more effective than radiotherapy-alone for treating nasopharyngeal carcinoma (NPC). The present study retrospectively evaluated the efficacy and toxicity of CCRT with docetaxel, cisplatin, and 5-fluorouracil (TPF) chemotherapy in patients with NPC. PATIENTS AND METHODS: The study regimen consisted of two cycles of TPF chemotherapy [docetaxel (90 mg/m(2)), cisplatin (60 mg/m(2)), and continuous 5-fluorouracil (600 mg/m(2)/day: 5 days)] during definitive radiotherapy. Radiotherapy was performed 5 days a week with a single daily fraction of 1.8 or 2.0 Gy totalling to 70-Gy doses. A total of 24 patients with NPC were enrolled and evaluated. RESULTS: Treatment completion rate was 70.8%, with an overall response rate of 100%. The 5-year overall survival rate was 82.4%, and 5-year progression-free survival rate was 78.3%. CONCLUSION: CCRT with TPF resulted in excellent survival rates for patients with NPC.

Predictive and prognostic value of metabolic tumor volume (MTV) in patients with laryngeal carcinoma treated by radiotherapy (RT) / concurrent chemoradiotherapy (CCRT).

PURPOSE: To evaluate the predictive and prognostic value of pretreatment metabolic tumor volume (MTV) in patients with treated by radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). METHODS: We reviewed the records of 118 patients with newly diagnosed laryngeal carcinoma, who had been treated by RT or CCRT. Pretreatment positron emission tomography (PET) was performed, and MTV values were obtained by contouring margins of standardized uptake value. Clinical factors and MTV were analyzed for their association with survival. RESULTS: Patients with residual disease showed a significantly higher MTV than those with a complete response (CR) after primary treatment. Univariate analysis showed that the patients with a high MTV had a significantly lower disease-free survival (DFS) (p < 0.001). Subsite (p = 0.010), T-stage (p < 0.001), nodal metastasis (p < 0.001) and clinical stage (p < 0.001) also correlated significantly with DFS. In the multivariate analysis, MTV and clinical stage were both found to be independent prognostic factors for DFS (p = 0.001, p = 0.034, respectively). The 3-year DFS for patients with a high MTV were significantly poorer than those with a low MTV (p < 0.001). CONCLUSIONS: MTV of the primary tumor is a significant prognostic factor for DFS in patients with laryngeal carcinoma treated by RT or CCRT. The results imply that MTV could be an important factor when planning treatment and follow-up for patients with laryngeal carcinoma.

Temporary facial nerve dysfunction after parotidectomy correlates with tumor location.

OBJECTIVE: To investigate the clinical factors associated with temporary facial nerve dysfunction (TFND) following surgery for benign parotid gland tumors. METHODS: We reviewed the records of 175 patients with benign parotid gland tumors who underwent partial parotidectomy at Yokohama City University Medical Center in Japan. TFND was found in 33 patients (18.9%). We used two hypothetical lines in magnetic resonance imaging (MRI) images to define the tumor location (upper/lower or anterior/posterior) in the parotid gland. We then studied the associations of TFND with the following clinical factors: patient age, tumor size, histopathological diagnosis, and the location of the tumor within the parotid gland (superficial lobe/deep lobe; upper part/lower part; and anterior part/posterior part). RESULTS: Tumors located in the upper parts, anterior parts or the deep lobes of the parotid gland had statistically higher incidences of TFND compared with tumors located in the lower parts, posterior parts or the superficial lobe (P<0.001, <0.001, <0.01, respectively). The odds ratio for the risk of TFND was significantly high if tumors were located in the upper parts, the anterior parts or the deep lobes with stepwise multivariate regression analysis. The other factors, including patient's age, tumor size, histopathology of the tumor, and inadequate surgeon's experience, were not apparent risks for TFND. CONCLUSIONS: Parotid gland tumors located in the upper parts, the anterior parts or the deep lobes had a higher risk of TFND. The two hypothetical lines we used were shown to be useful to define the tumor location, eventually the risk of TFND.

Chemoradiation as a definitive treatment for cervical lymph node metastases from unknown primary cancer.

AIM: To assess the treatment outcomes of chemoradiation for cervical lymph node metastases from an unknown primary site (CUP), and to identify for prognostic factors. PATIENTS AND METHODS: Thirty patients diagnosed as having CUP, and receiving chemoradiation as a definitive treatment were included in the analysis. Locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) rates were estimated, and the factors affecting treatment outcomes were analyzed. RESULTS: After a median follow-up period of 25 months for surviving patients, the two- and five-year LRC, DFS, and OS rates were 56%/45%, 46%/36%, and 69%/52%, respectively. On univariate analysis, lower performance status (PS; p=0.001), and limitation of disease to level 2 or 3 lymph nodes (p=0.009) were significantly associated with better DFS. Low PS (p=0.002) was significantly associated with better LRC. No late toxicity of grade 3 or greater was observed. CONCLUSION: Definitive chemoradiation for CUP was well-tolerated, with improvement of DFS/LRC for those with good PS and disease limited to level 2 or 3 lymph nodes.

Treatment results and prognostic factors for advanced squamous cell carcinoma of the larynx treated with concurrent chemoradiotherapy.

OBJECTIVE: To review our experience with concurrent chemoradiotherapy (CCRT) for patients with advanced resectable squamous cell carcinoma (SCC) of the larynx and to evaluate the factors affecting survival and larynx preservation. STUDY DESIGN: Retrospective study. SUBJECTS AND METHODS: The records of 102 patients with stage III or IV resectable SCC of the larynx treated with CCRT between February 1994 and March 2009 were reviewed. Of 102 patients, 59 were treated with high-dose regimens, including cisplatin, 5-fluorouracil (5-FU), methotrexate, and leucovorin or docetaxel, cisplatin, and 5-FU, and 43 were treated with low-dose regimens, including carboplatin and uracil-tegafur or S-1. Radiotherapy was delivered 5 days a week using a single daily fraction of 1.8­2.0 Gray (Gy), to a total dose of 66.0­70.2 Gy. Overall survival (OS), disease-specific survival (DSS), and DSS with larynx preservation were estimated using Kaplan­Meier methods. The log-rank test and Cox proportional hazards regression were used to identify significant prognostic factors for DSS and DSS with larynx preservation. RESULTS: The 5-year OS and DSS for all patients treated with CCRT were 63.9 and 70.7 %, respectively. The 5-year DSS with larynx preservation was 54.1 %. On multivariate analysis, N stage, synchronous multiple primary cancers, and the contents of chemotherapy were significant predictors of OS for patients undergoing CCRT; T stage, N stage, and the contents of chemotherapy were significant prognostic factors for larynx preservation. CONCLUSION: The treatment method including the indication for CCRT may be determined by the contents of the chemotherapy and the T and N stages of laryngeal SCC. It is important to diagnose multiple synchronous primary cancers before CCRT.

Comparison of concurrent chemoradiotherapy versus induction chemotherapy followed by radiation in patients with nasopharyngeal carcinoma.

PURPOSE: The study aimed to evaluate the efficacy of concurrent chemoradiotherapy (CCRT) with platinum-based chemotherapy as a primary treatment for nasopharyngeal carcinoma (NPC) and to further compare the results of CCRT with these of neoadjuvant chemotherapy (NAC) followed by radiotherapy (RT). PATIENTS AND METHODS: Before 1998, 21 patients with NPC received NAC followed by RT (NAC-RT). Between 1999 and 2008, a total of 25 NPC patients received CCRT. The CCRT group received a regimen including docetaxel (50 mg/m(2), day1), cisplatin (CDDP, 60 mg/m(2), day4) and continuous 5-fluorouracil (5-FU) infusion (600 mg/m(2), day 1-5), the TPF regimen, or a regimen including CDDP (60 mg/m(2), day4), continuous 5-FU infusion (600 mg/m(2), day 1-5), methotrexate (MTX, 30 mg/m(2), day 1) and leucovorin (LV, 20 mg/m(2), day 1-5), PFML regimen. The CCRT group received 2 cycles of chemotherapy during definitive RT. The NAC group of patients received a PFML regimen. RESULTS: The overall response rate after CCRT was 96%. The 3-year and 5-year disease-specific survival rates were 75.6% and 60.1%, respectively. In patients receiving NAC-RT, the 3-year and 5-year disease-specific survival rates were 84.1% and 67.3%, respectively. There was no difference observed in terms of survival rates between the group receiving CCRT and that receiving NAC-RT. CONCLUSION: CCRT with the TPF or PFML regimen was tolerable, and the NPC patients receiving this treatment showed excellent survival rates. In comparison to the group receiving NAC-RT, CCRT had no advantage in terms of the survival rate. In the future, the control of distant metastasis might play an important role in improving the survival rate of patients with advanced NPC receiving CCRT.
