Computed tomography-guided 125I seed interstitial implantation in the treatment of recurrent ovarian cancer

Objective The aim of this study was to evaluate the effectiveness and safety of percutaneous interstitial implantation with 125I seed under computed tomographic (CT) guidance for recurrent ovarian cancer (ROC). Materials and Methods A retrospective review was performed on 17 patients with ROC who were treated with 125I seed brachytherapy. Treatment planning system was used preoperatively to determine the estimated seeds number and distribution; 125I seeds were implanted into recurrent lesions under CT guidance. Therapeutic effectiveness and complications were noted during follow-up time. Results Months are counted from the time of 125I seed brachytherapy, and the median duration of follow-up was 10.5 months (3-23 months). The objective response rates after 1, 3, 6, 12, and 18 months were 76.5%, 75.0%, 61.5%, 42.9%, and 40%, respectively. The pain relief rate was 61.5%, and the general living quality was improved dramatically. The median progression-free survival time was 5.4 months, the median overall survival time was 11.3 months, and the 1-year survival rate was 41.2%. Complications in this study were very mild; severe adverse events such as massive bleeding, intestinal fistula, and treatment-related deaths did not occur. Conclusions Our initial experience showed that CT-guided 125I seed interstitial implantation is safe and feasible in the treatment of patients with ROCs after multiple therapies.ObjectiveThe aim of this study was to evaluate the effectiveness and safety of percutaneous interstitial implantation with 125I seed under computed tomographic (CT) guidance for recurrent ovarian cancer (ROC).

Sorafenib combined with cryoablation to treat unresectable hepatocellular carcinoma

ObjectiveTo evaluate the efficacy and tolerability of sorafenib combined with cryoablation in treating unresectable hepatocellular carcinoma (HCC).MethodsPatients with unresectable advanced HCC received cryoablation and sorafenib at a dose of 400 mg twice daily in 4-week cycles on the same day of the cryoablation. Tumor response, median overall survival and the median time to radiological progression were calculated and the toxicity was evaluated.ResultsSeventy-eight patients with unresectable HCC were involved in this study. The median age was 52 years (range, 22–81 years). The Eastern Cooperative Oncology Group (ECOG) performance status scores were 0 (39.7%), 1 (55.1%), and 2 (5.1%). Nine (11.5%) patients were at Barcelona clinic liver cancer (BCLC) stage A, twenty-four (30.8%) patients were at stage B and 45 (57.7%) patients were at stage C. Five (6.4%) achieved partial responses, and 34 (43.6%) achieved stable disease. The median time to progression (TTP) for all enrolled patients was 6.6 months and the median overall survival (OS) was 12.2 months.ConclusionCryoablation combined with sorafenib demonstrates good efficacy and acceptable tolerability in treating unresectable advanced HCC patients.

CT-guided 125 I brachytherapy for recurrent ovarian cancer

This retrospective study was to evaluate the local control and survival of 125I brachytherapy for recurrent ovarian cancer. 52 125I brachytherapy procedures were performed in 47 patients with 51 recurrent ovarian cancer lesions. The follow-up period was 1-55 months (median 12 months). The local control rate (LC) of 3, 6, 12, 24 and 36 months was 93.3%, 77.7%, 58.9%, 38.7% and 19.3%, respectively. Patients with tumor size ≤ 4cm (85.7% vs 40.0%, P = 0.037) and actual D90 between 110 to 130Gy (47.4% vs 66.7% vs 62.5%, P = 0.029) had better LC. The 1, 2 and 3 years of overall survival (OS) was 79.3%, 63.0% and 52.5%, respectively. The poor performance status (HR 3.821, 95% CI 1.383-10.555; P = 0.010), concurrent distant metastasis (HR 9.222, 95% CI 1.710-49.737; P = 0.010) and large postoperative residual tumor size (HR 6.157, 95% CI 1.438-26.367; P = 0.014) were closely correlated with a poor OS. Our data indicate thatCT-guided 125I brachytherapy is an effective and safe modality for the local treatment of recurrent ovarian cancer.This retrospective study was to evaluate the local control and survival of 125I brachytherapy for recurrent ovarian cancer. 52 125I brachytherapy procedures were performed in 47 patients with 51 recurrent ovarian cancer lesions.
