OBJECTIVEWith the extremity soft tissue sarcoma close to neurovascular bundle, combined en bloc resection and brachytherapy or simple en bloc resection were performed to evaluate the treatment outcome of the combined en bloc resection and brachytherapy.

METHODSRetrospectively investigation was performed for the extremity soft tissue sarcoma close to neurovascular bundle between 2000 and 2009. Inclusion criteria were primary extremity soft tissue sarcoma, MRI showed that the reaction zone involved the main neurovascular bundle, and the reaction zone closed less than 1 cm to the main neurovascular bundle. 86 cases were included in the study. There were 41 men and 45 women. The average age was 38.5 years old (Range from 15 to 73). There were malignant fibrous histiocytoma, synovial sarcoma, fibrosarcoma, liposarcoma, clear cell sarcoma, epithelioid sarcoma, leiomyosarcoma, rhabdomyosarcoma and vascular sarcoma etc. The stage were IA (8), IIA (12), IIB (10), IIC (7), III (43) and IV (6).

RESULTSDuring an average follow-up of 53 months (range 24 - 102 months), the distant metastasis rate 32.56% (28/86) and the lymph node metastasis rate was 6.98% (6/86). The local recurrence rates was 13.95% (12/86). In the group of combined en bloc resection and brachytherapy with 38 cases, the local recurrence rates was 5.26% (2/38). Four cases had wound infection and six cases had wound delay healing. The MSTS functional score was 21.11 ± 1.79. In the group of simple en bloc resection with 48 cases, the local recurrence rates was 20.83% (10/48). One case had wound infection and four cases had wound delay healing. The MSTS functional score was 84.23% (26.11 ± 1.79). The local recurrence rates was significant different between.

CONCLUSIONWith the extremity soft tissue sarcoma close to neurovascular bundle, combined en bloc resection and brachytherapy could decrease the local recurrence rate.

OBJECTIVETo evaluate the efficacy, toxicity and survival of intraoperative 125I brachytherapy combined with chemotherapy for advanced pancreatic cancer.

METHODSThirty-six patients with advanced pancreatic cancer were randomized to two groups: brachy-chemotherapy group (n = 18) and control group (n = 18). For the combined group, intraoperative 125I implantation and gemcitabine, 5-Fu were given. For the control group, intratumoral injection of absolute alcohol was done.

RESULTSThe CR + PR rate of brachy-chemotherapy group was 38.9% with pain relief in 77.8%, while that of control group was 0 with pain relief in 22.2% (P < 0.05). Although there were some toxicity in brachy-chemotherapy group, treatment was well tolerated. The 6-, 12-month survival rates of brachy-chemotherapy group were 71.4% and 21.4% and those of control group were 38.5% and 7.7%, respectively. The median survival time was 10.6 months and 5.2 months for the two groups, between which the difference was significant (P < 0.05).

CONCLUSIONInteroperative 125I brachytherapy combined with chemotherapy for advanced pancreatic cancer can control tumor, relieve pain and improve quality of life. It is safe and effective.
