Popis: 138 Background: Surgery is considered the best treatment for patients (pts) with non-metastatic locally advanced squamous cell carcinoma of the esophagus who have responded to neoadjuvant chemoradiotherapy (CRT) in terms of locoregional control. However, in these pts PFS and OS have not been proved superior to those achieved by CRT alone. Besides, the addition of surgery to CRT increases treatment-related morbidity and mortality. Unfit pts are usually declined for surgical procedures and included in definitive CRT programs. The aim of this study was to define the role of non-surgical strategies (CRT, CT or RT) in unfit pts considered non-optimal for surgical procedures. Methods: We retrospectively reviewed 90 pts with squamous cell carcinoma of the esophagus who had been diagnosed and treated at our institution from January 2004 to December 2009. Fifty-one pts were non-metastatic among which 19 underwent surgery and 32 a non-surgical procedure (CRT, CT, RT or BSC). Our aim was to identify OS, PFS, RR, data on comorbidity and toxicity in these 32 pts. Results: Thirty out of the 32 pts were men with a median age of 62 years (range 41-90). Comorbidity was detected in 17 pts (53%) as means of respiratory disorders (21.9%), cardiopathy (12.5%), hepatopathy (21.9%), synchronic tumors (25%) and metachronic tumors (25%). Seventeen pts received CRT, 7 received CT, 1 received RT and 7 received BSC alone (53%, 22%, 3% and 22% respectively). Grade 3 and 4 toxicities were observed in 15 pts (46.9%) as means of mucositis (18.8%), oesophagitis (15.6%), diarrhoea (12.5%) and neutropaenia (12.5%). One patient in the CRT group died of toxicity. RR was 43.8% (70.6% for CRT, 14.3% for CT alone). Median follow-up was 17.2 months. Median PFS was 11.3 ± 6.12 months (17.9 for CRT, 5.1 for CT alone). Median OS was 15.6 ± 7.6 months (6.9 for CT alone). Conclusions: Our experience with CRT alone in unfit pts with locally advanced squamous cell carcinoma of the oesophagus supports its use with a median PFS of 17.9 months and controllable toxicity. Data on median OS are lacking due to pending long-term follow-up. No significant financial relationships to disclose.
