AbstractObjective:In the treatment of locally advanced head and neck cancer (LA-HNC), both dose escalation and hypo-fractionation can improve tumour control rates with uncertain role of addition of concurrent chemotherapy. We aimed at developing a new radiotherapy protocol for patients not eligible to receive the standard concurrent chemo-radiation therapy (CCRT) with little toxicity profile.Methods:A total of 63 LA-HNC patients were randomised to receive either: 70 Gy in 35 fx in 7 weeks concurrently with cisplatin 100 mg/m2 every 3 weeks for 3 doses (Arm A) or 74 Gy in 33 fx in 6·5 weeks (Arm B). Volumetric modulated arc therapy plans were created for both treatment arms. We compared the local control (LC), progression-free survival (PFS), overall survival (OS) and acute and late toxicity between the two arms.Results:A total of 33 patients were in Arm A versus 30 patients in Arm B with median follow-up 24·2 months. No significant differences in LC, PFS and OS between the two arms. Complete remission occurred in 54·5 and 63·3% of patients in Arms A and B, respectively. All toxicities were significantly less in Arm B than Arm A.Conclusion:Slightly dose-escalated hypo-fractionated regimen is safe and feasible and has comparable efficacy and less acute and late side effects than conventional dose CCRT with avoidance of chemotherapy-related toxicities in LA-HNC patients.

BACKGROUND Concurrent chemotherapy is a well-established treatment modality for locally advanced head and neck cancer. The concept of concurrent chemotherapy and radiation was introduced in an attempt to improve the local control and possibly influence the survival because of the high rate of local and distant failures observed with the combination of surgery and postoperative radiation. The relevance of this study was to assess the efficacy of our treatment and patience compliance and also study the effect in patients treated with cisplatin based concurrent chemo radiotherapy in advanced head and neck cancer. METHODS The prospective study was conducted in the Department of Radiotherapy, Government Medical college, Thrissur, Kerala comprising the newly diagnosed patients with locally advanced head & neck cancers over one year. Conventional radiotherapy with a dose of 66 Gy in 33 fractions over 6.5 weeks was given concurrently with Inj cisplatin 100 mg / 2 IV every 3 weeks and periodically followed up for one year. RESULTS This study revealed that complete response rate was higher in 61 – 70 year age group compared to lower age groups. Complete response cases were slightly higher in T1 disease compared to higher stages. Regarding nodal status, complete response and DFS were more in N0 tumours and worst in N3 tumours. It was found that complete response rates were slightly higher in stage III than stage IV. Comparing the grade of the tumour, complete response cases were slightly higher in WD and MD compared to PD. Complete response rate and disease free survival (DFS) were slightly higher in cases who had more than two chemotherapy cycles compared to one cycle. CONCLUSIONS Concurrent chemo radiation was not well tolerated in our study group. Only 23.5 % patients were able to complete the planned treatment. The positive side was that complete response was found in about 79.4 % of study patients & DFS at one year was 80 %. KEY WORDS Concurrent Chemo Radiation, Head and Neck Cancer, Cisplatin

AbstractIntroduction:Currently, concomitant chemoradiation using cisplatin is one of the standards of care for the management of head and neck cancer, but at the cost of increased acute toxicity. Our aim was to assess whether vinorelbine was less toxic and of at least comparable efficacy, if not better, compared with cisplatin.Materials and methods:A total of 72 patients with squamous cell carcinoma in the head and neck region were recruited, 40 in arm A and 32 in arm B. Patients in arm A received 40 mg/m2 cisplatin weekly. Patients in arm B received 6 mg/m2 vinorelbine weekly. Both arms also received 66 Gy of radiation in conventional fractionation.Results and analysis:There was no statistically significant difference in response rate or toxicities between the two arms, except for nausea and/or vomiting, which was significantly less frequent in the vinorelbine arm.Conclusion:Vinorelbine was as effective as cisplatin in controlling locoregional disease in locally advanced head and neck cancer, but was only marginally less toxic than cisplatin.
