Abstract:
e17027 Background: Neoadjuvant chemotherapy administration is associated with significant amount of morbidity and around 2-3% mortality in the Western world protocol settings. In developing countries where malnourishment is prevalent, the same data might not apply. Methods: This analysis was performed on a database of patients undergoing NACT for oral cancers at our center from 2010- 2012. The toxicity was graded according to CTCAE version 4.02 scale. Descriptive analysis, univariate and multivariate analysis were performed to determine factors affecting toxicity. Results: There were 528 patients, the median age was 45 years (22-78 years). The regimens administered were TPF in 35 patients (6.6%) and taxane with platinum in the rest. At least one cycle of chemotherapy was taken at our center by 94.8% (494). The median number of cycles were 2. The any grade toxicity after 1 st cycle of chemotherapy were vomiting, diarrhea, mucositis, fatigue, febrile neutropenia (FN), peripheral neuropathy, hyponatremia, hypokalemia, hperkalemia, transaminitis were in 41.3% (204), 43.9% (217), 44.3% (219), 47.2% (233), 7.2% (35), 3.0% (15), 33.8% (167), 14.4% (71), 4.9% (24) and 12.3% (61).Toxicity details of second cycle of chemotherapy were available for 390 patients. The any grade toxicity after 2 nd cycle of chemotherapy were vomiting, diarrhea, mucositis, fatigue, febrile neutropenia, peripheral neuropathy, hyponatremia, hypokalemia, hyperkalemia, transaminitis were in 28.6% (113), 37.3% (108), 31.3% (124), 39.3% (116), 3.1 % (12), 3.2% (13), 19.7 % (74), 7.4% (30), 3.1% (12) and 4.9% (19). For diarrhoea, female sex, nutrition (BMI below 18.5 KG/m2) and use of 3 drug regimen were predictive. For development of mucositis only nutrition was predictive. Use of 3 drug regimen and overnourishment were predictive of FN. Use of 3 drug regimen and use of docetaxel were predictive for hyponatremia. On multivariate analysis for diarrhoea only nutrition was predictive (p=0.017), for FN both drug regimen (p=0.003) and over nutrition (p=0.035) were predictive and for hyponatremia only use of 3 drug regimen was significant (p=0.017). Conclusions: 3 drug regimen, malnourishment and use of docetaxel are important predictors of acute toxicity associated with NACT in oral cancers.
