title: An evaluation comparing Californium252 neutron brachytherapy with neoadjuvant intra-arterial embolism chemotherapy assisted surgery effect for treating advanced cervical carcinoma patients.
abstract: OBJECTIVE
  To compare the therapeutic and side effects of using Californium252 (252Cf) neutron brachytherapy with neoadjuvant intra-arterial embolism chemotherapy in combination with surgery for treating Stage Ib2-IIb cervical cancers (CCs).
  
  
  METHODS
  Thirty-two Stage Ib2-IIb CC patients were enrolled and randomly divided into two groups from January 2007 to April 2010 in the present Hospital. Prior to surgery within four weeks, a total of 17 cases were treated with 252Cf neutron brachytherapy (700-800 cGy doses at point A) once a week (Group A), and 15 cases were treated by neoadjuvant intra-arterial embolism chemotherapy using a combination of bleomycin, carboplatin, and cyclophosphamide twice (Group B). The clinical symptoms and signs, side effects, and relapse condition follow up until July 2013 were compared between the two groups for the perioperation.
  
  
  RESULTS
  Reductions in tumor mass and CR+PR were not significantly different between the groups before the surgery (p > 0.05). Abdominal pain and pelvic adhesions were significantly more severe in Group B (p < 0.05). There were no significant differences in surgical time, blood loss or the other side effects between Groups A and B (p > 0.05). The percentage of pelvic tumor recurrences in Group A was lower than that of the patients in Group B (11.8% vs 20.0%) although with no significant difference at present. No distant metastasis has been found in both two groups.
  
  
  CONCLUSIONS
  Except for less abdominal pain and pelvic adhesions, 252Cf neutron brachytherapy has perioperative effects similar to those of neoadjuvant intra-arterial embolism chemotherapy.
