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 03/2011; 12(3):344-51.

ABSTRACT: The incidence of maxillary sinus cancer (MSC) is extremely rare, representing less than 1% of all cancers. Because of its rarity, the management of locally advanced MSC is a challenging issue. The objective of the present study was to retrospectively compare the efficacy of 2 traditional treatment strategies, concurrent chemoradiotherapy (CCRT) versus combination of surgery and radiotherapy and/or chemotherapy (SRCT) in MSC. From 1989 to 2010, 65 patients with histologically confirmed stage III or IVA/IVB were retrospectively analyzed. The median age of our subjects was 60 years (range 36 to 81). The present study involved 18 women (27.7%) and 47 men (72.3%). Of the 65 patients, 52 (80.0%) had squamous cell carcinoma. The TNM stage was stage III, as determined by the American Joint Committee on Cancer, 6th edition, in 27 patients (41.5%). Stage IVA or IVB was observed in 38 patients (58.5%). Of the 65 patients, 41 underwent treatment. Of these 41 patients, 26 and 15 patients underwent SRCT and CCRT, respectively. During the 75.6 months (range 6.4 to 249.4) of median follow-up, the median progression-free survival duration was 45.1 months (95% confidence interval 0.0 to 142.7). The 5-year overall survival rate was 64.8%. However, the patients who had undergone surgery had better progression-free survival (hazard ratio 2.363, 95% confidence interval 1.098 to 5.085, P = .028) and overall survival (hazard ratio 4.989, 95% confidence interval 1.646 to 15.118, P = .004). The SRCT group had a better progression-free survival (P = .043) and overall survival (P = .029) duration than did the CCRT group. SRCT might be superior to CCRT for locally advanced MSC. Additional studies comparing the treatment outcomes of CCRT with SRCT are warranted.Journal of oral and maxillofacial surgery: official journal of the American Association of Oral and Maxillofacial Surgeons 09/2011; 70(7):1717-23.
