We employed 4 to 6 marks, depending on tumor location and size. The average marking duration was 14 minute (1 to 21\u2009min); the average surgery duration, 73 minute (37 to 143\u2009min). The smallest resection median margin was 2.0\u2009mm (1.0 to 5.0\u2009mm); the largest, 7.0\u2009mm (2.0 to 12.0\u2009mm).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n
