RESUMO
Objective: To evaluate the efficacy of concurrent Chemoradiation in patients with locally advanced inoperable squamous cell carcinoma of oral cavity in terms of local control and toxicity
Study Design: Case series
Place and Duration of Study: Institute of Nuclear Medicine and Oncology [INMOL], Lahore, from January 2008 to December 2013
Methodology: Sixty-nine patients with locally advanced inoperable oral cavity cancer, registered in INMOL hospital from January 2008 to December 2013 who fulfilled a pre-defined eligibility criteria, were enrolled in the study
Concurrent Chemoradiation protocol consisted of conventional fractionation delivering 70 Gy with weekly Cisplatin [50 mg/m[2]] during the course of radiation
Tumor response was calculated by RECIST criteria version 1.1 along with the median overall survival and disease-free survival. Acute treatment related toxicities were graded as [G]
Results: Thirty-six [52.17%] patients showed complete response; while 19 [27.54%], 8 [11.59%] and 6 [8.7%] were observed with partial response, stable and progressive disease, respectively. Treatment response was significant [p<0.001] in terms of responders vs. nonresponders to treatment. Median overall survival was 18.00 months; whereas, median disease-free survival remained 14.00 months. Main toxicities included mucositis [G3 and G4, 71%], xerostomia [G2 and G3, 82.5%], vomiting [G3 and G4, 51%], myelosuppression [G3 and G4, 26.2%], dermatitis [G3 and G4, 49.2%], and fatigue [G3 and G4, 57.9%]
Conclusion: Platinum based CCRT remained effective for inoperable oral cancer patients
