Poor tumor differentiation is an independent adverse prognostic variable in patients with locally advanced oral cavity cancer––Comparison with pathological risk factors according to the NCCN guidelines

This study aimed to review clinical experiences using whole-field simultaneous integrated boost (SIB) intensity-modulated radiotherapy (IMRT) and sequential IMRT in postoperative patients with oral cavity cancer (OCC). From November 2006 to December 2014, a total of 182 postoperative patients with OCC who underwent either SIB-IMRT (n = 63) or sequential IMRT (n = 119) were enrolled retrospectively and matched randomly according to multiple risk factors by a computer. The differences were well balanced after patient matching ( P = .38). The median follow-up time was 65 months. For patients treated with the SIB technique and the sequential technique, the respective mortality rates were 36.8% and 20.0% ( P = .04). The primary recurrence rates were 26.3% and 10.0% ( P = .02), respectively. The respective marginal failure rates were 26.7% and 16.7%. A multivariate logistic regression analysis showed that patients who received the SIB technique had a 2.74 times higher risk of death than those who received the sequential technique (95% confidence interval = 1.10-6.79, P = .03). Sequential IMRT provided a significantly lower dose to the esophagus (5.2 Gy, P = .02) and trachea (4.6 Gy, P = .03) than SIB-IMRT. For patients with locally advanced OCC, postoperative sequential IMRT may overcome an unpredictable geographic miss, potentially with a lower marginal failure rate in the primary area. Patients treated by sequential IMRT show equal overall survival benefits to those treated by SIB-IMRT and a lower mortality rate than those treated by SIB-IMRT. Additionally, a reduced dose to the esophagus and trachea compared to sequential IMRT was noted.

The Impact

Objectives: Evaluation of the hemostatic effect of trans-arterial embolization on patients with advanced oral cavity cancer who had bleeding complications while undergoing definitive concurrent chemoradiotherapy (CCRT). Additionally, assess the effect of trans-arterial embolization on treatment response following concurrent chemoradiotherapy, as well as overall survival (OS) and progression-free survival (PFS) in the group of patients following the intervention. Method: From September 2018–June 2021, a retrospective descriptive study was conducted on 16 patients with inoperable, locally advanced oral cavity cancer who received definitive concurrent chemoradiotherapy, experienced acute bleeding complications, and received selective intravascular intervention with various embolization materials at Vietnam National Cancer Hospital. Results: After selective embolization, 16/16 patients ceased bleeding; 1 patient re-bled for the second time after 3 weeks. The average duration of chemoradiotherapy interruption due to intervention was 6.7 days. After CCRT, 15/16 (93.75%) patients achieved a response, with 9/16 (56.25%) patients achieving a complete response. The median OS was 14 months (range, 3–26 months), and the median PFS was 10 months (range, 3–20 months). There were no significant complications, particularly neurological side effects. ConclusionsTumor bleeding is a common and serious complication of CCRT treatment in patients with locally advanced oral cavity cancer. Embolization is a safe and effective method of controlling acute bleeding that has no adverse effect on the outcome of definitive concurrent chemoradiotherapy.

Visual Screening

Introduction: The purpose of this study was to analyze the risk factors affecting precancerous lesions, and cancer of oral cavity, and to assess efficacy of visual screening for oral mucosal lesions. Methods: The medical records of patients older than 30 years of age with history of habitual cigarette smoking or betel quid chewing that received screening for oral mucosal lesions between January 2012 and December 2012 were retrospectively reviewed. The patients' age, gender, risk factors, screening findings, and histopathology results of biopsy were included for further analysis. Results: A total of 1341 patients were enrolled in this study. There were 1080 males and 261 females ranging from 30 to 96 years of age, with a mean age of 53.9±13.6 years. After screening, 226 (16.9%) were found to be positive of oral lesions. Among these 226 patients, 69 (30.5%) underwent biopsy under local anesthesia, and the histopathology showed malignancy in 13 (5.8%). All of the confirmed malignant cases were squamous cell carcinoma. Among them, 12 received further staging examination and one was lost to follow-up resulting in unknown stage. The early stage oral cavity cancer (stage I and II) accounted for 84.6% (11/13). Conclusions: The detection rate of early stage oral cavity cancer in our study was reasonable. Therefore, visual screening for oral cavity cancer is recommended for patients with habitual cigarette smoking or betel quid chewing.

Oral Cavity Carcinoma

Abstract Background: Oral cavity cancer is the most common cancer among rural India. There is a paucity of data for outcomes of operable oral cavity cancer from rural India. Use of maintenance metronomic may delay or avoid relapse. Aim: To evaluate outcomes of operable oral cavity carcinoma and evaluate impact of maintenance metronomic chemotherapy. Objectives: To evaluate disease-free survival (DFS), overall survival (OS), and factors affecting the outcome in operable oral cavity cancer. Materials and Methods: Data of patients diagnosed with oral cavity cancer registered between May 2008 and May 2014 were retrieved. Only those patients with operable oral cavity cancer and upfront definitive surgery were included in the study. Demographic profile, stage, tobacco consumption, adjuvant therapy, and pattern of failure were collected. Kaplan-Meir survival analysis was used to determine DFS and OS. Log-rank test was used to evaluate factors affecting outcome. Results: Median follow-up is 24 months. Out of 335 patients, 225 (67%) had advanced operable cancer with 42/225 (18%) and 183/225 (82%) as Stages III and IVA, respectively. Buccal mucosa was the most common subsite (178/335, 53%) followed by tongue (63/335, 19%). Ninety-two percent patients were addicted to smokeless tobacco, whereas 27% were smokers. Median DFS is 13 months with 2 years relative DFS 32%. Median OS is 30 months, with 2 years OS of 54%. Metronomic adjuvant oral chemotherapy was given in 130/225 (58%); Stage III and IVA patients with median of 14 months (3-18 months). Use of metronomic chemotherapy improved DFS (8 vs. 14 months, P = 0.22) and OS (14 vs. 26 months, P = 0.04). Conclusion: Oral cavity cancer is a major health care problem in rural India. Presentation at advanced stage leads to suboptimal outcomes. Benefit of metronomic maintenance chemotherapy in locally advanced oral cavity needs to be further evaluated prospectively.
