Comparative evaluation of quality of life in oral cancer patients undergoing 3-dimensional conformal radiation therapy with or without concomitant chemotherapy - A longitudinal study.

OBJECTIVES: To assess and compare the quality of life (QOL) in Oral Cancer patients undergoing 3-DCRT with or without concomitant Chemotherapy at three different time intervals. MATERIALS AND METHODS: This unicentric longitudinal study included 50 patients of oral cancer undergoing 3-DCRT with or without concomitant chemotherapy. QOL was recorded using the EORTC H and N 35 Questionnaire at baseline, end of treatment (EOT), and 3 months after treatment. RESULTS: Maximum deterioration of most QOL domains were noted at End of treatment (EOT) in all the patients. A highly statistically significant difference was noted between different time intervals with the highest scores noted at the EOT (P < 0.01). There was a statistically significant difference in patients undergoing 3DCRT with chemotherapy when compared to those with 3DCRT without chemotherapy (P < 0.05). CONCLUSION: There is substantial deterioration in QOL at the EOT after head-neck irradiation by 3-DCRT with or without concomitant Chemotherapy although it gradually improves over time. However, 3DCRT results in clinically meaningful and statistically better QOL scores at 3 months after treatment compared to baseline and EOT.

Basal cell adenoma of the floor of the mouth masquerading as ranula- A rare case in an unusual location.

A 65-year-old female patient with a history of wearing a denture for 15 years reported with a complaint of pain in the floor of the mouth. On examination, a swelling measuring about 2.2 X1.2 cms was noted in the floor of the mouth on the left side. The lesion was excised under local anesthesia. Histopathology revealed a cystic lesion with basaloid cells arranged in tubules, nests and cribriform pattern. A diagnosis of basal cell adenoma was made and confirmed by immunohistochemistry. We report a rare case of Basal Cell Adenoma of the floor of the mouth which mimicked a ranula. The predominantly cystic nature of this basaloid tumor posed a diagnostic challenge. Histopathological and immunohistochemical analysis to arrive at a definitive diagnosis aid in treatment planning and prognostication.

Comparative evaluation of oral mucositis in oral cancer patients undergoing 3-dimensional conformal radiation therapy and intensity modulated radiation therapy with or without chemotherapy.

Context: Oral cancer is a significant cause of death across the world. A combined multimodal approach integrating surgery and radiation therapy (RT) with or without chemotherapy (CT) is commonly employed in advanced oral cancer to prevent recurrences and locoregional spread. Oral mucositis is a common acute toxicity reported in patients undergoing RT and CT. The delivery of optimal cancer therapy protocols is compromised due to morbidity caused by oral mucositis. Aims: To compare the severity of oral mucositis in oral cancer patients undergoing 3-Dimensional Conformal Radiation Therapy (3DCRT) and Intensity Modulated Radiation Therapy (IMRT) with or without concomitant CT. Settings and Design: This was a prospective, unicentric and longitudinal study conducted in a cancer centre. Methods and Material: One hundred four patients with locally advanced oral cancer were enrolled in this study. Fifty-two patients were treated with IMRT and 52 patients with 3DCRT to a dose of >60 Gy, along with concurrent cisplatin weekly CT. Mucositis was recorded before the start, in the end, 1 month, and 3 months post-chemoradiotherapy treatment. Statistical Analysis Used: Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) software (v. 21.0, Chicago. 2012). Descriptive and frequency statistics were performed for different parameters assessed in 3DCRT and IMRT group. Results: Grade 3 mucositis was the most predominant grade observed in both groups at the end of treatment. Thirty-six patients (69.3%) versus 24 patients (46.1%) developed grade 3 mucositis in 3DCRT and IMRT group, respectively (P = 0.013). Healing was better with IMRT group when compared to 3DCRT group 1 month and 3 months post-RT. Mucositis was severe in patients undergoing concomitant CT. Conclusions: IMRT reduced the incidence of severe mucositis and also improved the treatment-compliance compared to 3DCRT in locally advanced head neck cancer patients treated by chemoradiotherapy.
