BACKGROUND & OBJECTIVE: H101 is an E1B-55 kDa gene-deleted replication-selective adenovirus, which showed a significant antitumor activity. This study was to compare effects and toxicities of intratumoral H101 injection combined with cisplatin plus 5-fluorouracil (PF) regimen or adriamycin plus 5-fluorouracil (AF) regimen versus PF or AF regimen alone in treating patients with head and neck or esophagus squamous cell cancer. METHODS:A total of 160 patients were recruited. PF regimen (cisplatin 20 mg/m(2) ivgtt, qd x 5d; 5-fluorouracil 500 mg/m(2) ivgtt, qd x 5d) was administered to patients have no history of PF chemotherapy,or sensitive to PF chemotherapy,while AF regimen (adriamycin 50 mg/m(2) iv,d1; 5-fluorouracil 500 mg/m(2) ivgtt, qd x 5d) was administered to patients didn't response to PF regimen. All patients were randomized to either receive intratumoral H101 injection (5.0x 10(11)-1.5 x 10(12) VP/day for 5 consecutive days every 3 weeks) or not. Treatment repeated every 3 weeks,all patients have to receive at least 2 cycles of chemotherapy. RESULTS: Among 123 accordant patients,overall response rate of PF plus H101 group (group A1) was 78.8% (41/52),of PF alone group (group B1) was 39.6% (21/53),of AF plus H101 group (group A2) was 50.0% (7/14),of AF alone group (group B2) was 50.0% (2/4). Differences of response rates between group A1 and group B1,between group A1+A2 and group B1+B2 were significant (P=0.000). Main side effects were fever (45.7%), injection site reaction (28.3%),and influenza-like symptoms (9.8%). CONCLUSION: Intratumoral H101 injection showed a distinct efficacy in patients with squamous cell cancer of head and neck or esophagus,and was relatively safe.
