[Percutaneous intratumoral injection with pingyangmycin lipiodol emulsion for treatment of recurrent sacrococcygeal chordomas].

Objective: To evaluate the effectiveness and safety of fluoroscopy-guided percutaneous intratumor injection of pingyangmycin lipiodol emulsion (PLE) in the management of recurrent sacrococcygeal chordomas.

Methods: Seven patients with recurrent sacrococcygeal chordomas presenting with severe local pain with visual analogue score (VAS)≥8 received treatment sessions of fluoroscopy-guided percutaneous intratumor injection of PLE. The patients were followed up every 3 months after the last session to assess their clinical responses and observe the changes in the tumor size measured by computed tomography.

[Three-dimensional conformal radiotherapy combined with transcatheter arterial chemoembolization for massive primary liver cancer].

Objective: To evaluate the outcomes of patients with unresectable massive primary liver cancer (PLC) receiving three-dimensional conformal radiotherapy (3-DCRT) combined with transcatheter arterial chemoembolization (TACE).

Methods: From January 2001 to December 2004, 84 patients with unresectable massive PLC (tumor size> or =10 cm) received 3-DCRT combined with TACE, including 49 cases in UICC/AJCC T(3) stage and 35 cases in T(4) stages. Lymph node metastasis was found in none of the patients, and portal vein tumor thrombosis (PVTT) was detected in 30 cases.

[Percutaneous intradiscal oxygen-ozone injection for lumbar disc herniation: no need of perioperative antibiotic prophylaxis].

Objective: To evaluate the feasibility of no antibiotic administration to prevent infection during the perioperative period of percutaneous intradiscal ozone-injection for treatment of lumbar disc herniation.

Methods: Seventy-two patients with lumbar disc herniation but normal body temperature as well as normal results of three routine tests (blood, urine, stool) and C-reactive protein (CRP) level were randomly divided into two groups. The patients in prophylaxis group were given cephalothin V(2.

[Necessity of prophylactic antibiotics in patients with primary liver cancer undergoing transcatheter arterial chemoembolization: a prospective study].

Objective: To investigate the necessity of prophylactic administration of antibiotic in patients with primary liver cancer undergoing transcatheter arterial chemoembolization (TACE).

Methods: Sixty patients without preoperative infection were randomized into two groups to receive a single dose of cefazolin (PA group) prior to TACE or no prophylactic antibiotics (NONE group). The incidence of postoperative infection was compared.
