Abstract
Background. Rectal laterally spreading tumors (LSTs) are macroscopically divided into granular (LST-G) and non-granular (LST-NG). LST-Gs have in turn two types: homogeneous and nodular mixed.
Subjects and methods. The retrospective study analyzed the data of 20 patients (11 men and 9 women) in whom homogenous LSTs were removed by argon plasma coagulation (APC). The patients» mean age was 65.8 ± 6 years. Therapeutic effectiveness was evaluated by Ki-67 proliferation index and the frequency of complications and recurrences.
Results. The average size of removed homogeneous LST-Gs was 12.3 ± 3.8 cm2. The average number of APC sessions to achieve a LST-G reduction was 4.4 ± 0.9. Three days before APC, Ki-67 in the neoplasia biopsy specimens amounted to as much as 67.8 ± 4.4 % on average; it reduced to an average of 33.0 ± 3.0 % at 14 days of APC initiation, 16.5 ± 1.8 and 4.2 ± 0.4 % after 21 and 180 days, respectively.
Discussion. Inability to receive complete histological data on removed LST-Gs is a main pitfall in APC.
Conclusion. Stepwise tumor APC may be the method of choice in elderly and senile patients with a family history of comorbidity. APC can precisely remove LSTs along the boundary of the dentate line. This technique requires no single-use tools.
