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: Sinonasal carcinomas are uncommon neoplasms accounting for approximately 3% to 5% of all upper respiratory tract malignancies. Sinonasal malignancies in most cases do not cause early symptoms and present in an advanced stage of disease. Exact staging necessitates a clinical and endoscopic examination with biopsy and imaging. Tumor resection using an open or endoscopic approach is usually considered the first treatment option. In general, sinonasal carcinomas are radiosensitive, so adjuvant or neoadjuvant radiation treatment may be indicated in advanced disease. Multidisciplinary surgical and medical oncologic approaches, including ablation and reconstruction, have enhanced the survival outcome over the past few decades.Neurosurgery clinics of North America 01/2013; 24(1):39-49.

ABSTRACT: Squamous cell carcinoma arising at maxillary sinus is a rare neoplasm, characterized by aggressive growth pattern and glooming prognosis. There are no studies describing specifically its epidemiology in the South America. The aim of the current paper is to characterize a Brazilian maxillary sinus squamous cell carcinoma sample and to compare such data with others worldwide relevant series. The records of the Brazilian National Cancer Institute (1997-2006) were gathered and plotted. Additionally, an extensive literature review was carry out using electronic database (PUBMED/MEDLINE and LILACS) over a period of 54 years. A descriptive statistics and univariate survival test (log rank) were employed. Maxillary sinus squamous cell carcinoma was the commonest malignancy of sinonasal epithelium found. It affected mainly mid-age white men and most of them were diagnosed at advanced stage. Surgery combined with radiotherapy was the most therapeutic modalities given. The overall mortality rate in our sample was of 65.5%. Overall 1-, 2- and 5-year survival rate was 57.9%, 44.8%, and 17.7%, respectively. Maxillary sinus squamous cell carcinoma is an aggressive tumor normally diagnosed at the advanced stage and most patients present an unfavorable prognosis and reduced survival rate.International journal of clinical and experimental pathology 01/2014; 7(12):8823-32. · 1.78 Impact Factor
