ABSTRACT

PURPOSE: To estimate the radiation dose and biodistribution of (18)F-5-fluorouracil ([(18)F]-5-FU) from positron emission tomography/computed tomography (PET/CT) data, and to extrapolate mouse data to human data in order to evaluate cross-species consistency. METHODS: Fifteen cancer patients (head and neck cancer (n=11), colon cancer (n=4)) were enrolled. Sequential PET/CT images were acquired for 2h after intravenous administration of [(18)F]-5-FU, and the percent of the injected dose delivered to each organ was derived. For comparison, [(18)F]-5-FU was administered to female BALB/cAJcl-nu/nu nude mice (n=19), and the percent of the injected dose delivered to mouse organs was extrapolated to the human model. Absorbed radiation dose was calculated using OLINDA/EXM 1.0 software. RESULTS: In human subjects, high [(18)F]-5-FU uptake was seen in the liver, gallbladder and kidneys. The absorbed dose was highest in the gallbladder wall. In mice, the biodistribution of [(18)F]-5-FU corresponded to that of humans. Estimated absorbed radiation doses for all organs were moderately correlated, and doses to organs (except the gallbladder and urinary bladder) were significantly correlated between mice and humans. The mean effective [(18)F]-5-FU dose was higher in humans (0.0124mSv/MBq) than in mice (0.0058mSv/MBq). CONCLUSION: Biodistribution and radiation dosimetry of [(18)F]-5-FU were compared between humans and mice: biodistribution in mice and humans was similar. Data from mice underestimated the effective dose in humans, suggesting that clinical measurements are needed for more detailed dose estimation in order to ensure radiation safety. The observed effective doses suggest the feasibility of [(18)F]-5-FU PET/CT for human studies.

ABSTRACT

The aim of this study was to verify the effectiveness of PET (positron emission tomography) or PET/CT (fusion images of PET with computed tomography) in detecting synchronous cancer in patients with head and neck carcinoma. We reviewed 682 patients with carcinoma of the head and neck between January 2001 and December 2010. In 98 patients, 111 synchronous cancers were diagnosed. Of these 98 patients, the index cancer was predominantly located in the hypopharynx (47 cases), followed by the larynx (23 cases), oropharynx (12 cases) and the oral cavity (6 cases). Esophageal cancer was diagnosed as the most synchronous cancer (57 lesions), followed by gastric cancer (20 lesions), lung cancer (9 lesions) and head and neck cancer (8 lesions). Among these 98 patients, PET or PET/CT was performed in 82 patients. Of these 82 patients, PET or PET/CT detected 34 out of 94 (36.2 %) synchronous cancers. No significant difference was observed between PET and PET/CT in terms of lesion detectability (p = 0.21). Regarding synchronous T1 and Tis upper gastrointestinal (UGI) cancer, PET or PET/CT detected 4 out of 43 (9.3 %) of the cancers. No statistical difference in detectability was observed in patients who underwent PET or PET/CT scanning before or after histological examination of synchronous UGI cancer. In conclusion, synchronous cancer was most frequently observed in the UGI, especially in the esophagus in patients with head and neck carcinoma. PET and PET/CT have limitations in the detection of these lesions.

ABSTRACT

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.

ABSTRACT

Congenital cholesteatoma of the tympanic membrane is rare, and lesions without a history of otitis media or any other adverse events involving the tympanic membrane are extremely rare. We report two cases of this lesion; one was a 3-year-old girl who underwent removal of a cholesteatoma using retroauricular approach and a partial myringoplasty with an underlay technique, and the other was a 2-year-old girl in whom a cholesteatoma was enucleated without grafting. This disease is thought to be of embryonic origin.

ABSTRACT

OBJECTIVE: This study evaluates the utility of fluorodeoxyglucose-positron emission tomography (FDG-PET) in patients with head and neck squamous cell carcinoma (HNSCC) who received concurrent chemoradiotherapy (CCRT). METHODS: Sixty-five patients were recruited for this study between November 2002 and April 2007. The FDG-PET scan was performed before treatment and 4-6 weeks after treatment. RESULTS: The mean of maximum standardized uptake value (SUVmax) before treatment at the primary tumor site was 8.1 (range, 2-22). The sensitivity of FDG-PET for the diagnosis of primary tumor site was 98%. The mean of SUVmax after treatment was 2.6 (range, 2-5). The sensitivity, specificity, and accuracy of FDG-PET for the diagnosis of primary tumor site after treatment were 100%, 40%, and 46%, respectively. The mean of SUVmax before treatment at the nodal site was 4.7 (range, 2-16). The mean of SUVmax after treatment was 2.0 (range, 2-6.7). The pre-treatment SUVmax of T2, T3, and T4 stages were significantly higher than that of the T1 stage. The N stage had no correlation in terms of the pre-treatment nodal site SUVmax. CONCLUSION: Our results indicate that FDG-PET is a useful imaging method for evaluating the response of CCRT in patients with HNSCC. However, performing FDG-PET 4-6 weeks after treatment may be too early as it may give false-positive results due to fibrosis and scarring.

ABSTRACT

OBJECTIVE: In radiotherapy and chemotherapy tumor hypoxia is recognized as a major obstacle to effective treatment. We undertook a pilot study in patients with locally advanced head and neck cancer to determine whether there is a relationship between tumor uptake of (62)Cu-ATSM and response to chemoradiotherapy. METHODS: Seventeen patients were studied using PET/CT with (62)Cu-ATSM and (18)F-FDG prior to the initiation of radiotherapy and chemotherapy. All patients had locally advanced head and neck cancer (stage III or IV). Tumor uptake in all patients was measured by region of interest analysis using the maximal standardized uptake value (SUVmax). A total dose of 50.4-70.2 Gy (median 70.2 Gy) was delivered in 29-39 fractions (median 39 fractions) to tumor. In patients with (non CR) and without (CR) residual/recurrent tumors at 2-year post irradiation, the statistical significance of the differences in tumor (62)Cu-ATSM SUVmax, T/M ratio, (18)F-FDG SUVmax and tumor volume were analyzed using Student's t test and Welch test. The relationship between clinical outcome and (62)Cu-ATSM/(18)F-FDG uptake patterns was analyzed using Kruskal-Wallis test. The correlation between SUVmax of (62)Cu-ATSM and (18)F-FDG was compared by Spearman's rank correlation test. RESULTS: Two of the 17 patients that were enrolled in our study were excluded from the final analysis. Of the 15 remaining patients, 9 patients were free of disease and 6 patients had residual/recurrent tumors. The SUVmax differed significantly (p < 0.05) between patients with or without residual/recurrent tumor on (62)Cu-ATSM PET/CT. Six of the 10 patients with tumors SUVmax >5.00 had residual/recurrent tumor, whereas all of the 5 patients with tumors SUVmax <5.00 were free of disease. There was no significant difference in FDG uptake between patients with and without residual/recurrent tumor. CONCLUSIONS: The results of this pilot study suggested that (62)Cu-ATSM uptake may be a predictive indicator of tumor response to chemoradiotherapy in patients with locally advanced head and neck cancer.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the feasibility and toxicity of concurrent chemoradiotherapy (CCRT) with docetaxel, cisplatin (CDDP) and 5-fluorouracil (5-FU) (TPF regimen) or with CDDP, 5-FU, methotrexate and leucovorin (PFML regimen) in previously untreated patients with advanced oropharyngeal squamous cell carcinoma (SCC). METHODS: Fifty-six eligible patients with stage III or IV oropharyngeal SCC were treated with CCRT. Forty-four patients were men and 12 were women, and the average age of the patients was 58.8 years (range, 37-72 years). In the TPF group, patients received CCRT with the TPF regimen [docetaxel (50 mg/m(2), day 1), CDDP (60 mg/m(2), day 4) and a continuous 5-FU infusion (600 mg/m(2)/day, days 1-5)]. In the PFML group, patients received CCRT with the PFML regimen [CDDP (60 mg/m(2), day 4), a continuous 5-FU infusion (600 mg/m(2)/day, days 1-5), methotrexate (30 mg/m(2), day 1) and leucovorin (10 mg/m(2)/day, days 1-5)]. The total radiation dose was between 66.6 and 70.2 Gy. RESULTS: The overall 5-year survival rate was 64.6% in all patients, 68.6% in the resectable group and 47.4% in the unresectable group. The 5-year disease-specific survival rate was 72.2% in all patients, 78.1% in the resectable group and 47.7% in the unresectable group. Regarding clinical stage, the 5-year disease-specific survival rates were 91% in stage III, 72% in stage IVa and 44% in stage IVb. CONCLUSION: CCRT with TPF or PFML regimen for advanced oropharyngeal SCC is tolerable and effective, especially in patients with resectable disease.

ABSTRACT

Mucosal melanoma of the head and neck (MMHN) is a rare malignant tumor associated with a poor prognosis. A retrospective study of case records of patients treated at our department between 1992 and 2010 was carried out. Thirteen patients were enrolled. The median age of the patients (3 males and 10 females) was 61 years (range 39-78). The median follow-up period was 48 months (range 10-115). Two common primary sites were the nasal cavity (8 cases) and sinonasal complex (5 cases). Ten patients (77%) received curative surgery. Chemotherapy was administered to 10 patients. In addition, lymphokine-activated killer (LAK) cell therapy was administered to 7 patients as adjunctive immunotherapy after the initial treatment course. The overall 5-year, cause-specific survival rate was 56%. Patients who received adjunctive LAK cell therapy had a survival rate of 67% at 5 years, while patients who did not receive adjunctive LAK cell treatment had a survival rate of 33%. MMHN is associated with a poor survival rate. The most common cause of death is distant metastasis. Surgery, radiotherapy and chemotherapy are common strategies for MMHN, but the control of metastasis is difficult. The use of immunotherapy remains uncommon for MMHN. However, from the viewpoint of a systemic disease, due to its high rate of metastases, immunotherapy using LAK cell treatment may contribute to the improvement of prognosis in patients with MMHN.

ABSTRACT

The aim of this study was to verify the effectiveness of positron emission tomography (PET) in detecting primary sites in carcinoma of unknown primary (CUP) patients. In this study, CUP represented a group of heterogeneous tumors that shared the clinical manifestation of metastatic carcinoma with no obvious primary site at the time of first diagnosis, which included clinical investigations, computed tomography, magnetic resonance imaging and panendoscopy. We reviewed the records of 24 patients with CUP between January 1995 and December 2009. The patients who demonstrated additional tracer uptake sites other than previously known metastatic lesions by PET scan were done direct biopsies for the sites of accumulation. Patients who had a negative PET scan or for whom the primary site could not be identified by direct biopsies underwent examination under anesthesia of the at-risk occult tumor sites. PET scan demonstrated focal accumulation suspicious for primary tumor in 12 (50.0%) of 24 patients: tonsil 5, nasopharynx 3, hypopharynx 1, tongue 1, larynx 1, and maxillary sinus 1. A subsequent biopsy of these sites revealed primary cancer in 9 (37.5%) of 24 patients: tonsil 5, nasopharynx 1, hypopharynx 1, tongue 1, and maxillary sinus 1. In the remaining three patients, no malignant cells were found by the biopsy of the accumulated area: nasopharynx 2, larynx 1. PET scans increase the yield of primary tumor by 37.5%. The sensitivity, specificity for PET scan were 80.8, 76.9%, respectively. PET scanning is useful in detecting primary cancer of CUP patients.

ABSTRACT

We compared concurrent chemoradiotherapy (CCRT) with docetaxel, cisplatin (CDDP), and 5-fluorouracil (5-FU) (TPF) with CCRT with CDDP, 5-FU, methotrexate and leucovorin (PFML) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) in terms of safety and efficacy on survival. A total of 100 patients were enrolled. The TPF group received CCRT with the TPF regimen [docetaxel (50 mg/m(2): day 1), CDDP (60 mg/m(2): day 4), and continuous 5-FU infusion (600 mg/m(2)/day: days 1-5)]. In the PFML group, patients received CCRT with the PFML regimen [CDDP (60 mg/m(2): day 4)], continuous 5-FU infusion (600 mg/m(2)/day: days 1-5), methotrexate (30 mg/m(2): day 1) and leucovorin (20 mg/m(2)/day: days 1-5)]. Both groups received 2 cycles of chemotherapy during definitive radiotherapy. The total radiation dose was between 66.6 and 70.2 Gray. The overall response rates after CCRT were 98 with 90% of a pathologically complete response (pCR) in the TPF group and 94 with 77% in the PFML group. For grade 3/4 adverse events, mucositis was more frequent in the PMFL group, and the TPF group showed a higher incidence of hematological toxicity. CCRT with TPF or PMFL for advanced SCCHN was tolerable and produced excellent survival rates.

ABSTRACT

18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a nuclear medicine imaging technique which has been increasingly applied as a diagnostic tool. The usefulness of FDG-PET may be described as follows: I . Early detection of cancer; II. Diagnosis of cancer; III. Detection of nodal or distant metastasis, and double cancer; IV. Detection of unknown primary tumor with metastatic neck lesions; and V. Evaluation of treatment of head and neck cancer. FDG-PET is especially useful to detect distant metastasis, double cancer with head and neck cancer and unknown primary tumor with metastatic neck lymph nodes. The conventional modalities, e. g., CT or MRI, show anatomical images in the body. On the other hand, FDG-PET reveals three-dimensional images of functional processes of the glucose metabolism. FDG-PET can estimate metabolic activity in cancer and is useful in evaluating or monitoring the response to concurrent chemoradiotherapy of the head and neck cancer. However, we should recognize the limitations of FDG -PET. An acute inflammatory disease shows high FDG uptake like cancer. It is difficult to detect early-stage esophageal cancer or to diagnose parotid gland cancer.

ABSTRACT

We report two successful remnant and recurrent cases of head and neck cancer treated with S-1. Case 1, a 52-year-old man, was diagnosed as supraglottic laryngeal carcinoma (T3N2cM0, squamous cell carcinoma: SCC) on January 25, 2000, and concurrent chemoradiotherapy (CCRT) was applied. After the treatment, a remnant tumor in the larynx was found by biopsy. He was followed using UFT at 400mg/day because he had refused surgery. Pulmonary metastasis was detected by chest CT on June 14, 2001, and the administration of S-1 was started. After 2 courses, the mass in the lung disappeared, and the primary lesion was also judged to be a complete response(CR). The administration of S-1 is still continuing and remnant tumors have not been found. Case 2, a 76-year-old man, was diagnosed with hypopharyngeal carcinoma (T3N2bM0, SCC) on December 14, 2001, and CCRT was applied resulting in CR in the hypopharynx and the neck. He was followed using UFT at 300 mg/day after discharge. A supraclavicular lymph node became palpable on March 27, 2003. Pathological examination by fine needle aspiration cytology showed SCC, class V. After 2 courses administering S-1 at 100mg/day, the supraclavicular lymph node disappeared. S-1 was changed to UFT at 300 mg/day on July 31, 2003, because adverse events of grade 3 appeared. Administration of UFT was continued for one year. No recurrence has been found for 5 years.

ABSTRACT

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) remains a significant problem for patients and is associated with a substantial deterioration in quality of life; appropriate use of antiemetic drugs is crucial in maintaining the quality of life in patients undergoing chemotherapy. METHODS: This randomized, crossover trial evaluated the antiemetic efficacy and safety of 8 mg per day (low-dose) and 16 mg per day (standard-dose) dexamethasone, in combination with the 5-HT(3) receptor antagonist granisetron, in 36 patients receiving cisplatin (CDDP)-containing chemotherapy for head and neck cancer. Following chemotherapy, the antinausea/vomiting inhibition rate for each dexamethasone dose was measured. RESULTS: During the 24-h period following administration of chemotherapy (acute phase), the antinausea/vomiting inhibition rates (no nausea and no episodes of vomiting) for 8 mg and 16 mg dexamethasone were comparably high (58.3% and 63.8%, respectively; P = 0.8092). Similar results were seen on days 2-5 following chemotherapy. Efficacy during the acute phase, based on the number of instances of vomiting and degree of nausea, was also comparably high for the two dexamethasone doses (overall efficacy rates were 94.4% and 88.8%, respectively, for 8 mg and 16 mg dexamethasone; P = 0.7637). Both doses maintained an 80% or higher response rate until day 3, and neither dose produced severe side effects. CONCLUSION: The results suggest that granisetron and dexamethasone combination therapy is useful in controlling acute and delayed nausea and vomiting induced by CDDP-containing chemotherapy for head and neck cancer. Furthermore, 8 mg and 16 mg dexamethasone have equivalent antiemetic efficacy.

ABSTRACT

BACKGROUND: Although the survival rate of early-stage laryngeal squamous cell carcinoma (SCC) patients treated by radiotherapy (RT) is sufficient, the larynx preservation rate is unsatisfactory. To improve the larynx preservation rate, such patients have been treated by RT with chemotherapeutic agents. PATIENTS AND METHODS: RT with or without uracil-tegafur (UFT) was performed for T1 cases, and UFT and carboplatin for T2 cases. RESULTS: In T1 cases, 30 patients received RT and 16 patients received concurrent chemoradiotherapy (CCRT). In T2 cases, 28 patients received RT and 45 patients received CCRT. There were no significant differences in the response and survival rates between the treatment methods both in T1 and T2 cases. The 5-year larynx preservation survival rate was improved significantly by CCRT in T2 cases (66.7% vs. 93.3%; p < 0.01). CONCLUSION: CCRT for early-stage laryngeal SCC patients was efficacious to improve the larynx preservation survival rate.

ABSTRACT

PURPOSE: The aim of our study was to prospectively evaluate whether intravenous contrast media in integrated positron emission tomography and computed tomography (PET/CT) with (18)F-fluorodeoxyglucose ((18)F-FDG) significantly contributes to evaluation of primary head and neck cancers compared with unenhanced PET/CT, regional contrast-enhanced CT of head and neck (neck CE-CT) and regional magnetic resonance imaging of head and neck (neck MRI). METHODS: Subjects were 42 consecutive patients (35 men, 7 women; age range: 36-91 years) with biopsy-proven primary head and neck cancers. Lesion detection of primary and nodal sites and TNM classification were assessed on a per-patient basis. McNemar test and kappa statistics were employed for statistical analyses. RESULTS: Forty patients (95%) were successfully followed up: 24 patients had nodal disease and 3 had distant metastasis. Contrast-enhanced and unenhanced PET/CT detected 98 and 95% of the primary tumours, respectively, and both detected 92% of patients with nodal disease, which revealed no statistically significant difference. Accuracy for T status was 75 and 73%, respectively, which proved significantly more accurate than neck CE-CT, which had an accuracy of 53% (p = 0.0133 and 0.0233, respectively). Neck MRI correctly classified the T status in 58% of patients; however, no statistically significant difference was found between PET/CT and neck MRI. Contrast-enhanced PET/CT, unenhanced PET/CT, neck CT and neck MRI correctly staged the N status in 90, 90, 79 and 90% of patients, respectively, with no statistically significant difference. Overall TNM classification was correctly classified in 68 and 65% of patients, respectively. Weighted kappa values between enhanced and unenhanced PET/CT for primary tumour detection, nodal detection, T status and N status were 0.655, 1.000, 0.935 and 1.000, respectively. CONCLUSION: We found almost perfect correlation between enhanced and unenhanced PET/CT for lesion detection and initial staging of primary head and neck cancers. Routine contrast administration for PET/CT imaging may not be justified.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the feasibility and toxicity of concurrent chemoradiotherapy (CCRT) with S-1 in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) in elderly cases and/or cases with comorbidity. METHODS: Fifty eligible patients with stage III (15 cases) or stage IV (35 cases) SCCHN were treated with CCRT. Thirteen cases had an advanced age of over 75 years and 37 cases had comorbidity. Definitive radiotherapy was delivered up to a total dose of 66-70.2 Gy. The patients received two courses of oral S-1 (40 or 50 mg twice a day [80 or 100 mg/day]) for 2 weeks followed by 1 week of rest while receiving CCRT. RESULTS: All the patients received the planned radiotherapy and at least one course of S-1. Grade 3 mucositis occurred in 20% of the patients (10/50). Grade 3 neutropenia occurred in 12% (6/50) and leukocytopenia occurred in 6% (3/50) of the cases. Pathologically, the complete response rates were 93% in stage III and 54% in stage IV. CONCLUSION: Concurrent chemoradiotherapy with S-1 is a safe, well-tolerated and effective regimen for locally advanced SCCHN in elderly cases and/or cases with comorbidity.

ABSTRACT

OBJECTIVE: Combined treatment modality, e.g., definitive surgery followed by radiotherapy (RT) and definitive RT with concurrent chemotherapy, has been applied for advanced maxillary sinus squamous cell carcinoma (MSSCC) patients to obtain a better survival with organ preservation in Japan. METHODS: The outcome of 40 patients with MSSCC between 1991 and 2007 in our institute was analyzed retrospectively. There were 36 males and 4 females, the average age being 59.5 years (ranging from 34 to 81 years). The median follow-up time was 66.1 months. All the patients had received a combined treatment consisting of definitive surgery, RT, and intra-arterial or systemic chemotherapy. The chemotherapeutic regimen was different depending on the performance status and/or complications of the patients. Since 1998, concurrent chemoradiotherapy with cisplatin, 5-fluorouracil, methotrexate and leucovorin regimen (CCRT-PFML) instead of neo-adjuvant chemotherapy has been applied. RESULTS: The overall 5-year survival rate was 59.2%, the 5-year disease-specific survival rate was 71.7%, and the 5-year organ preservation survival rate was 42.4%. In the group receiving CCRT-PFML, the overall 5-year survival rate was 60.0%, the 5-year disease-specific survival rate was 76.0%, and the 5-year organ preservation survival rate was 60.3%. CONCLUSION: CCRT-PFML for advanced MSSCC patients is feasible to preserve the organs without reducing the survival rate.

ABSTRACT

OBJECTIVE: To review our experience in the treatment of concurrent chemoradiotherapy (CCR) for patients with advanced squamous cell carcinoma of the head and neck (SCCHN) and to evaluate the different factors affecting survival and primary organ preservation. METHODS: We reviewed the records of 101 patients with SCCHN treated with CCR between February 1998 and April 2004. Of 101 patients, 76 were treated with a cisplatin, 5-fluorouracil, methotrexate, and leucovorin (PFML) regimen and 25 were treated with a carboplatin and uracil-tegafur (CBDCA-UFT) regimen. Overall survival (OS), disease-specific survival (DSS) and DSS with primary organ preservation were estimated using Kaplan-Meier methods. The log-rank test and Cox proportional hazards regression were employed to identify significant prognostic factors for OS, DSS, and DSS with primary organ preservation. RESULTS: The 5-year OS and DSS for all patients were 51.6 and 67.4%, respectively. On multivariate analysis, resectability of the tumor and degree of histological differentiation were significant predictors of survival for patients undergoing CCR; T stage and differentiation were significant prognostic factors for primary organ preservation. CONCLUSION: In the treatment of CCR for advanced SCCHN, the survival rate of the patients with resectable tumors was excellent and significantly greater compared with the patients with unresectable tumors. T1 to T3 disease in patients with advanced resectable SCCHN is a good predictor of organ preservation. CCR may improve not only primary organ preservation (local control) but also survival in patients with poorly differentiated tumors.

ABSTRACT

OBJECTIVE: One reason for the difficulty in accurate preoperative pathological diagnosis of major salivary gland tumors with fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET) is the tendency of pleomorphic adenomas to have a high, standardized uptake value (SUV). The expression of glucose transporter 1 (GLUT1) and the quantity of GLUT1 messenger RNA (mRNA) were analyzed in specimens of pleomorphic adenoma to identify whether GLUT1 is responsible for the increased glucose uptake in FDG-PET examinations of these tumors. METHODS: Eighty salivary gland tumors resected at Yokohama City University Hospital were retrospectively investigated. FDG-PET was performed prior to surgery. PET images were evaluated by two experienced radiologists. GLUT1 was immunohistochemically stained, and GLUT1 mRNA density was quantified using real-time polymerase chain reaction in 10 of 40 pleomorphic adenomas. RESULTS: The pleomorphic adenomas stained positively for GLUT1, and there was significant correlation between the GLUT1 index and the SUV in FDG-PET. CONCLUSIONS: GLUT1 is expressed in salivary gland pleomorphic adenomas. Furthermore, the GLUT1 index shows significant correlation with the SUV of FDGPET. This result suggests that GLUT1 plays an important role in increasing FDG uptake in salivary gland pleomorphic adenomas.
