Introduction:
Radiation plays a major role in treatment of locoregional control of Head and Neck Squamous cell carcinoma (HNSCC). Anaemia is considered a contributor to intra-tumour hypoxia and tumour resistance to ionizing radiation and most evidences are from developed world, we prospectively investigated the exact role of anaemia in treatment outcome of Stage III/IVA HNSCC in our patient population.
Aim Of The Study:
Primary end point: To analyse the Pre-Radiotherapy haemoglobin level and early response of treatment in stage III/IVA HNSCC and to determine the relationship of Pre-Radiotherapy haemoglobin level with other prognostic factors.
Materials And Methods:
This non-interventional single blinded randomized study enrolled patients attending the OPD consecutively, who met our eligibility criteria.
Inclusion Criteria:
HNSCC patients of Stage III/IVA aged ≥18 years and ≤ 70 years with ECOG status of 1or 2 and willing for concurrent chemoradiation and at least 6 weeks of follow up.
Exclusion Criteria:
1) Previous history of treatment for malignancy or radiation in head and neck site. 2) Patients with other fatal and non-fatal pre-morbid or co-morbid conditions that can affect the outcome or the overall survival. Patients with Pre-radiotherapy haemoglobin status < 10 g/dl were given haematinic support and/or blood transfusion. All patients received concurrent chemotherapy (weekly cisplatin) and radiation in conventionally fractionated dose of 66Gy. Early treatment responses were evaluated with Revised RECIST version 1.1 and Data analysis using SPSS version 17.0.
Results:
Ninety one patients enrolled had mean age of 55.63 (range: 32-69), a median of 56 and mode of 60. Seventy one were males (78%) and 20 females (22%) with a performance status of ECOG 1 in 43 (47%) patients and ECOG 2 in 48 (53%); Pre-RT Hb level of <10.7 g/dl in 38 (42%) patients and ≥10.7 in 53 (58%) patients; Pre-RT Hb level was <12 g/dl in 67 (74%) patients and ≥12 in 24 (26%) patients. Tumour sites were - Nasopharynx 7 (8 %), Oral Cavity 18 (20 %), Oropharynx 32 (35 %), Hypopharynx 23 (25 %) and Larynx 11 (12 %). Twenty five (27%) had Grade 2 mucositis and 66 (73%) had Grade 3 mucositis. Fifty eight (64%) patients completed treatment with NO breaks and 33 (36%) with treatment breaks for ≥5 days. Pre-radiotherapy haemoglobin ≥ 10.7 g/dl (p < 0.001), ECOG performance status (p = 0.0002), Treatment interruptions for > 5 days (p = <0.0001), Mucositis reaction (p = <0.0001) showed statistical significance with outcome of response.
Conclusion:
The study found that performance status, pre-RT haemoglobin level, radiotherapy interruptions > 5 days and non-development of grade III mucositis was found to be significantly associated with good loco-regional control. Haemoglobin level ≥10.7 g/dl was associated with better treatment outcome, higher performance status, fewer treatment interruptions and lesser degree of mucositis. Transfusion did not affect the outcome. Definitive conclusions and recommendations need further expansion of our study for better statistical power.
