A Comparative Study of Two Chemo-Radiation Regimens for the Cancer of Larynx

The region of head and neck is critical for respiration, nutrition, and speech. The management of laryngeal tumours can stimulate mutilations and cosmetic deformities and worsen the life. A “non-operative approach” is preferred for patients to whom radiation following surgery, possibly, will direct severe functional destruction predominantly in advanced stage patients having a bulk of carcinoma larynx. The case material for the study was selected from the cross-section of patients registered at the J. K. Cancer Institute, Kanpur. Histologically squamous cell carcinoma 64 patients were registered and equally and randomly placed into Arm I and Arm II. “Arm I” patients and “Arm II” was comprised of randomly selected 64 patients, having histopathologically proven squamous cell carcinoma of the larynx. All patients (32 patients) belonging to “Arm I” received concurrent chemoradiotherapy of Inj. Cisplatin 100 mg/m2 for three-weekly underwent EBRT with 60 Co/LINAC and photon radiation of 70 Gy in 35 fractions for 7 weeks (2 parallel opposed fields). All the patients (32 patients) belongs to “Arm II” received chemo boost as Inj. Cisplatin 6 mg/m2 on last 15 fractions of treatment underwent EBRT with 60 Co/ LINAC photon radiation of 70 Gy in 35 fractions for 7 weeks. Radiotherapy was delivered in supine position by parallel opposing fields including the primary tumour, disease extension, and neck nodes. The study concluded that the loco-regional responses are analogous in Arm I and Arm 2, however Arm II had additional treatment allied toxicities and resulting from numerous of treatment breaks.
