eComment. The definition of neuroendocrine tumour and sublobar resection.

ranged between 51.9% [9] and 86.7% [11], with many series not providing either or both of these data. As a result, a lobectomy or greater resection was necessary on anatomical or diagnostic grounds and led to a low number of sublobar resections in these series. No series compared postoperative morbidity between lobectomy or greater resection and sublobar resection. Owing to the high heterogeneity within and between series, small numbers of peripheral tumours and low reporting rates of disease recurrence and postoperative morbidity, it is difficult to draw conclusions. There is a lack of comprehensive randomized studies to compare a lobectomy or greater resection and sublobar resection. Although a typical carcinoid is reported as having good long-term disease-free prognosis, there is little objective evidence to show the equivalence or superiority of a lobectomy over sublobar resection in terms of disease recurrence and longterm survival. With an atypical carcinoid, there is insufficient data that can be used for evidence-based practice.
