Distribution of symptoms within subgroups stratified according to the recurrence site and number of lesions (solitary or multiple). The numbers in the bars indicate percentages and their 95% confidence intervals. Abdominal pain, abdominal distention, and intestinal obstruction, as shown in Supplementary Table 1, were categorized as abdominal discomfort. Vulva swelling was included as a limb symptom. Respiratory symptoms and chest pain were combined as respiratory symptoms and/or chest pain. Generally, the symptoms were specific to the recurrence site and lesion number.
