The efficacy and safety of concurrent chemoradiotherapy for maxillary sinus squamous cell carcinoma patients.
ABSTRACT 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.
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.
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%.
CCRT-PFML for advanced MSSCC patients is feasible to preserve the organs without reducing the survival rate.

ABSTRACT: The objective of this preliminary investigation was to evaluate the test-retest reliability of a new pain assessment method referred to as 3-D pain mapping. In Study 1, 101 chronic noncancer pain patients from four sites reported their pain using the method on two occasions (separated by approximately 10 days). The patients marked intensity, surface location, and depth of pain on a 3-D computer display of a male or female body. The model body could be rotated in order to mark multiple pain locations. In Study 2, 25 patients from a single site were tested with a revised version of the mapping program used in Study 1. Each patient gave ratings on two occasions separated by approximately 1 week. In Study 1, the intra-class correlations of the 3-D pain mapping measures were moderate to high for maximum pain intensity (0.73), vertical location of the point of maximum pain (0.94), and the number of pain marks (0.84). Correlations were low for the horizontal location of the point of maximum pain (0.56) and for the depth of pain (0.50). In Study 2, using the revised program, intra-class correlations were moderate for pain intensity (0.76), and high for the vertical (0.99) and horizontal (0.98) locations of the point of maximum pain, number of pain marks (0.89), and the depth of pain (0.84). Three-dimensional pain mapping enables patients to report the location and intensity of their pain on all parts of the body, and such ratings are highly reliable. Future studies are needed to determine whether the clinical value of this method can improve the accuracy of pain diagnoses and the quality of pain management.Pain Medicine 01/2011; 12(3):344-51. · 2.46 Impact Factor

ABSTRACT: 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). 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. 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. CCRT with TPF or PFML regimen for advanced oropharyngeal SCC is tolerable and effective, especially in patients with resectable disease.Cancer Chemotherapy and Pharmacology 01/2011; 68(4):855-62. · 2.80 Impact Factor
