RESUMO

Introduction: Cancer pain is known to be one of the Most severe pain anyone in life and is the primary reason for discontinuation of treatment.Sphenopalatine ganglion block (SPGB) can be useful in alleviating pain of carcinoma buccal mucosa. The study aims to analyze the effect of transnasal SPGB in pain management of patients suffering from carcinoma buccal mucosa. Materials and Methods: It was a hospital‑based study done on 150 patients with carcinoma buccal mucosa using a prospective cross‑sectional study design. To do statistical analysis, paired t‑test was used having SPSS software. Results: On visual analogue scale, intensity of pain was found to be notably reduced from 7.42±2.02 to 3.45±1.21 (P < 0.0001), after first sitting. Preprocedure and postprocedure morphine requirement were 90.24 ± 30.24 and 60.42 ± 0.93 mg/day (P > 0.05) At the conclusion of study, the results were found to be statistically significant. Conclusion: Transnasal SPGB is beneficial in improving patient compliance and reducing pain scores and morphine requirement in patients suffering from carcinoma buccal mucosa

RESUMO

Introduction: Several studies regarding tumor-stroma ratio (TSR) in colorectal, esophageal, breast, endometrial, and cervical carcinomas have been done in the past with significant results. Objectives: The objectives of this study were to (1) study and grade TSR in buccal mucosa and tongue squamous cell carcinoma (SCC), (2) grade inflammatory cell infiltrate surrounding the tumor, and (3) correlate the above two parameters with tumor grade, lymph node metastasis, lymphovascular invasion (LVI), and perineural invasion (PNI). Materials and Methods: Totally, 25 patients of buccal SCC and 16 cases of tongue SCC were included in the study. TSR was assessed visually on the hematoxylin and eosin-stained tissue sections by two independent observers. Cases were categorized into two groups: One with high TSR >50% (stroma poor) and the other with low TSR <50% as the stroma-rich group. TSR was correlated with tumor size, lymph node metastasis, inflammatory cell infiltrate, LVI, and PNI. Data were analyzed by the Statistical Package for the Social Sciences version 16.0 (Chicago, IL, USA) for Windows. The Chi-square and Fischer's exact tests were applied in the analysis of categorical variable. Results and Conclusion: SCC of buccal mucosa showed a significant correlation between TSR and size of the tumor (P = 0.001). We found that smaller the tumor size ≤2 cm (Stage T1), lesser the TSR, and size >2 cm was found to be associated with higher TSR. Hence, higher TSR (stroma poor) was associated with an adverse pathological characteristic, i.e., advanced T significantly. There was no significant correlation between TSR and inflammatory infiltrate with grade of the tumor, lymph node metastasis, LVI, and PNI. In 16 cases of SCC of the tongue; no correlation was observed between TSR and inflammatory infiltrate with tumor size, grade of the tumor, lymph node metastasis, LVI, and PNI. TSR has been studied in various malignancies (mostly adenocarcinomas) including laryngeal SCCs; however, it has never been studied on oral SCCs

RESUMO

Purpose/Objective(s): In India > 1 million new cases of cancer diagnosed every year. 40-50% of these cases are of head and neck cancer because of tobacco overuse. In our institute we have almost 1000-1300 new cases of Carcinoma Buccal Mucosa reported every year. From which 70-75% are surgically operable. For post-operative Radiotherapy treatment, we treat most of our patients by 2 Dimensional conventional treatments. Purpose of this study is to assess toxicity & long term results of postoperative carcinoma buccal mucosa cases treated by 2 Dimensional conventional treatment planning. Materials/Methods: From January 2009 to January 2012, almost 1980 postoperative cases of Carcinoma Buccal mucosa were referred for radiotherapy treatment. From which 1584 cases were suitable for postoperative 2 Dimensional Conventional planning. In selected cases, 71%, 18%, 11% cases were of Stage IV, III, II (close margin) respectively. Postoperative chemotherapy and radiotherapy was indicated in 475 patients. For all patients Plaster of Paris cast was prepared & X-ray was taken on Simulator machine. Target volume was drawn on x-ray & treatment plan generated on contour drawn with 90-95% isodose line covering the target, with hot spot of +10% on 2D Plato treatment planning system. All patients were treated with unilateral Anterior Posterior Lateral wedge pair technique for buccal mucosa and unilateral lower neck was given in indicated patients. Dose prescribed was 60 Gy/30#, 2Gy/#, 5 days a week, total 6 weeks treatment. Treatment plan verified on day 2 and treatment started. In patients where postoperative chemotherapy and radiotherapy was used, chemotherapy was given Cisplatin 30mg/m2 every weekly for 6 weeks. In most of the patients, treatment break was not required. All patients completed treatment successfully. Patients were assessed for locoregional control, acute & late toxicity and followed up for 3 years for disease free survival and overall survival. Results: Grade II & III acute mucositis was 82% & 18% respectively in 1109 patients who received only postoperative radiotherapy. For patients who received postoperative radiotherapy and chemotherapy Grade II and Grade III acute mucositis was seen in 75% & 25% respectively and side effects related to Cisplatin were managed conservatively. Almost all patients had Grade II skin reactions. Grade III skin reactions were observed in 8% of patients on post operative radiotherapy alone and 19% of patients on postoperative radiotherapy and chemotherapy but were manageable. All patients tolerated treatment well. For 1584 patients, follow up dropout rate was 20%. None of the patients developed significant late toxicity. As opposite parotid spared, no late complication of xerostomia observed. For 1268 patients, 1-, 2-, 3- year locoregional control rates were 82%, 75%, 68% respectively. Disease free survival rate was 63% (799 patients) & overall survival was almost 55% (697 patients) at median follow up for 40 months. Conclusion: 2D Conventional Radiotherapy Treatment Planning in our set up has shown very good results with almost 50% survival rates. It is less toxic treatment with fewer complications & less time consuming. It is highly cost effective treatment approach & results are very much encouraging.
