The role of neoadjuvant therapy in the treatment of locally advanced squamous cell cancer of the cervical oesophagus]

Cervical oesophagus represents a critical location for squamous cell carcinoma, which usually requires extensive surgery (pharyngo-laryngo-oesophagectomy). In the last decade, neoadjuvant chemo-radiotherapy was reported to be beneficial in the treatment of locally advanced squamous cell oesophageal cancer.Between November 1997 and January 2012, 55 patients with locally advanced (T3-4) squamous cell oesophageal cancer received preoperative chemo-radiotherapy, where the tumour was localized in the upper third. Patients received preoperative irradiation of 3960 cGy in 180 cGy fractions and simultaneously Cisplatin and 5-FU chemotherapy. Restaging was carried out after four weeks and patients considered operable were underwent surgery.In patients with cervical oesophageal cancer 35 of 55 (64%) underwent oesophageal resection or pharyngo-laryngectomy. In 16 out of 35 resected specimens (46%) complete histopathological remission (pCR) was observed. Perioperative mortality and anastomotic leaks were the same: 5/35 (14%). R0 resection rate was 82% and the 2- and 5 years survival rates were 41% and 18%. In 19 cases a larynx preserving pharyngo-oesophagectomy was performed and a free jejunal graft was used for reconstruction after a pharyngo-laryngectomy in 11 cases.The high rate of pCR (46%) confirmed that upper third oesophageal cancer has superior sensitivity to multimodal treatment. In 30 cases neoadjuvant chemo-radiotherapy was able to achieve tumour regression and render pharyngo-laryngo-oesophagectomy unnecessary.
