ConclusionsCompared with larynx cancers salvage rates are poorer for hypopharyngeal cancers and the role of primary surgery seems to be significantly higher and more decisive in overall survival (OS). Hypopharyngeal cancers therefore warrant a closer follow-up after an organ preservation protocol, to detect recurrence at the earliest stage and plan for an effective salvage surgery.ObjectiveTo evaluate the survival and morbidity of patients treated by surgery for carcinoma of the larynx and hypopharynx according to site.Patients And MethodsAll patients who had undergone laryngectomy at the Division of Surgical Oncology Regional Cancer Center (RCC) from June 1995 to December 2005 were included in the study, which retrospectively recorded the age and sex distribution, TNM stage, indication, type of laryngectomy and reconstructive option used. The therapeutic outcome, disease-free survival (DFS), OS, voice preservation and postoperative voice rehabilitation were analysed.ResultsOf a total of 167 cases, 123 (74%) had salvage surgery for failed chemoradiotherapy/radical radiotherapy and 44 (26%) had primary surgical treatment. Conservation surgery was undertaken in 4 cases, near total laryngectomy or pharyngectomy (NTL/NTLP) was done in 14 and total laryngectomy (TLPE) with gastric pull up was done in 5. Total laryngectomy (TL) or TL with partial or subtotal pharyngectomy was done in 144 cases. Concomitant neck dissection (ND) was done in 46 cases, 14 posterolateral selective, 15 radical neck dissections (RNDs), 2 extended RNDs, 12 bilateral NDs and 3 modified neck dissections (MNDs). Five patients received platinum-based neoadjuvant chemotherapy and nine had postoperative chemotherapy. In 116 patients the pharyngeal remnant was closed primarily, 21 patients had pectoralis major myocutaneous flap patch reconstruction, 18 had tubed pectoralis major myocutaneous (PMMC) flap reconstruction, 4 had folded (bipaddled) PMMC flap reconstruction, 7 had PMMC and 3 patients had deltopectoral (DP) flap for skin cover. Pathological margin positivity was seen in seven cases and perinodal disease was seen in nine. There was a statistically significant survival difference between salvage and primary surgical cases among cancers of the larynx and hypopharynx. Hypopharyngeal salvage rate was significantly lower in the present study. Sixty-two (37%) patients had postoperative leaks. Five leaks persisted to form pharyngocutaneous fistulae. All of these patients had either wound infection with or without flap necrosis or previous radiation. Two were repaired and in two cases speech prosthesis insertion was possible due its anatomical position. One patient refused further surgical closure after a partially failed repair. Fifty-six (34%) patients recurred locoregionally, 4 (2.3%) patients developed a second primary and 5 (2.9%) had distant metastasis. Thirty patients were voice rehabilitated with an electronic larynx. Seventeen patients had voice prosthesis insertion (6 primary and 10 secondary), 3 patients developed good oesophageal speech and voice preservation was possible in 18 patients. Seventy-nine patients were alive at the time of completing the study.
