RESUMO

We aim to compare the outcomes of patients undergoing R0 esophagectomy by a multidisciplinary team (MDT) with outcomes after surgery alone performed by surgeons working independently in a UK cancer unit. An historical control group of 77 consecutive patients diagnosed with esophageal cancer and undergoing surgery with curative intent by six general surgeons between 1991 and 1997 (54 R0 esophagectomies) were compared with a group of 67 consecutive patients managed by the MDT between 1998 and 2003 (53 R0 esophagectomies, 26 patients received multimodal therapy). The proportion of patients undergoing open and closed laparotomy and thoracotomy decreased from 21% and 5%, respectively, in control patients, to 13% and 0% in MDT patients (chi2 = 11.90, DF = 1, P = 0.001; chi2 = 5.45, DF = 1, P = 0.02 respectively). MDT patients had lower operative mortality (5.7%vs. 26%; chi2 = 8.22, DF = 1, P = 0.004) than control patients, and were more likely to survive 5 years (52%vs. 10%, chi2 = 15.05, P = 0.0001). In a multivariate analysis, MDT management (HR = 0.337, 95% CI = 0.201-0.564, P < 0.001), lymph node metastases (HR = 1.728, 95% CI = 1.070-2.792, P = 0.025), and American Society of Anesthesiologists grade (HR = 2.207, 95% CI = 1.412-3.450, P = 0.001) were independently associated with duration of survival. Multidisciplinary team management and surgical subspecialization improved outcomes after surgery significantly for patients diagnosed with esophageal cancer.

RESUMO

Haemoglobin A2 levels were assessed using a modular high performance liquid chromatography (HPLC) system with a protocol designed for the measurement of haemoglobin A1C. There was good correlation (r = 0.96; P < 0.001) between this technique and the International Committee for Standardisation in Haematology (ICSH) recommended method of microchromatography. The range of haemoglobin A2 was found to be 2.3-3.2% in apparently normal individuals, and 4.0-6.7% in those with beta-thalassaemia trait. The HPLC system produced reliable results quickly for haemoglobin A2 with no alteration to the protocol used for measuring haemoglobin A1C.
