Abstract PurposeThis study sought to analyze the predicting role of dosimetric parameters for nonclassic radiation-induced liver disease (RILD) after helical tomotherapy (HT) in Child-Pugh (CP) class A primary liver carcinoma (PLC) patients.Patients and methodsA total number of 71 CP class A PLC patients treated with HT from June 2011 to June 2015 were retrospectively reviewed. Clinical characteristics and dose-volume histogram (DVH) were recorded, and liver functions were followed up for 4 months after radiotherapy.ResultsIn all, 57 patients (80.3%) were male, and 14 (19.7%) were female, with a median age of 53 years. The mean gross tumor volume (GTV) was 226.8 cm3. A median dose of 55.0 Gy was delivered by HT with a median fraction size of 2.6 Gy. Twelve patients (16.9%) were diagnosed with nonclassic RILD. The mean dose to normal liver (MDTNL) and the percentage of total liver volume receiving more than 25 - 35 Gy irradiations (V25 - V35) were related to nonclassic RILD. MDTNL showed the highest AUC (0.705, p=0.026). The optimal cut-off value of MDTNL was 21.3 Gy with a sensitivity, specificity and accuracy of 83.3%, 62.7% and 67.6%, respectively. The tolerable volume percentages for DVH were less than: V25 of 42.3%, V30 of 33.9%, and V35 of 28.3%.ConclusionThis study suggests that MDTNL, V25, V30 and V35 are dosimetric predictors for nonclassic RILD in CP class A PLC patients. MDTNL < 21.3Gy, V25 < 42.3%, V30 < 33.9%, and V35 < 28.3% may be used to optimize HT planning.

Purpose: To evaluate factors associated with survival following transarterial 90Y (yttrium) radioembolization (TARE) in patients with advanced intrahepatic cholangiocarcinoma (ICC). Methods: This retrospective multicenter study analyzed the outcome of three tertiary care cancer centers in patients with advanced ICC following resin microsphere TARE. Patients were included either after failed previous anticancer therapy, including relapse after surgical resection, or for having a minimum of 25% of total liver volume affected by ICC. Patients were stratified and response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria at 3 months. Kaplan–Meier analysis was performed to analyze survival followed by cox regression to determine independent prognostic factors for survival. Results: 46 patients were included (19 male, 27 female), median age 62.5 years (range 29–88 years). A total of 65% of patients had undergone previous therapy, while 63% had a tumor volume > 25% of the entire liver volume. Median survival was 9.5 months (95% CI: 6.1–12.9 months). Due to loss in follow-up, n = 37 patients were included in the survival analysis. Cox regression revealed the extent of liver disease to one or both liver lobes being associated with survival, irrespective of tumor volume (p = 0.041). Patients with previous surgical resection of ICC had significantly decreased survival (3.9 vs. 12.8 months, p = 0.002). No case of radiation-induced liver disease was observed. Discussion: Survival after 90Y TARE in patients with advanced ICC primarily depends on disease extent. Only limited prognostic factors are associated with a general poor overall survival.

Cystic Liver

In a subset of autosomal dominant polycystic kidney disease patients, hepatic cysts dominate the clinical picture. These patients may develop polycystic liver disease, and enlargement of the liver leads to compression of adjacent abdominal and thoracic organs. The main risk factors for growth of liver cysts are female sex, exogenous oestrogen use, multiple pregnancies, and severity of renal disease. Treatment is only indicated in those with symptoms, and choice of treatment depends on total liver volume, size, and location of the liver cysts. Current radiological and surgical therapies include aspiration-sclerotherapy, fenestration, segmental hepatic resection, and liver transplantation. They all are palliative in nature and are partially effective and have non-negligible morbidity and mortality. Somatostatin analogues are still in development for polycystic liver disease.

Background Percutaneous transhepatic portal vein embolization (PTPE) can increase the future liver remnant (FLR) volume before extended liver resection; however, there is no current consensus regarding the best embolic material for PTPE. Purpose To evaluate the efficacy of PTPE using gelatin sponge particles and coils. Material and Methods The medical records of 136 patients who underwent PTPE using gelatin sponge particles and metal coils were retrospectively reviewed. We evaluated the procedural details, liver volume on CT, and clinical status before and after PTPE. Results The mean FLR volume increased significantly from 390 ± 147 cm3 to 508 ± 141 cm3 ( P < 0.001). A mean of 22.1 ± 9.4 days after PTPE, the mean increase in the ratio of FLR volume to total liver volume was 9.4 ± 6.5%. Complications related to PTPE occurred in five patients, including arterial damage (n = 4) and biloma (n = 1). The white blood cell count and C-reactive protein level increased significantly and then returned to baseline within seven days. Aspartate aminotransferase and alanine aminotransferase showed no significant changes. Fever (defined by the Common Terminology Criteria for Adverse Events v4.0) was reported in 74 patients (54%), but it was generally mild (Grade 1/2; n = 72). None of the patients experienced severe complications that required cancellation of surgery. Conclusion PTPE with gelatin sponge particles and coils may impose low physical stress on patients and is a safe method of inducing a significant increase of FLR.

Abstract Objective We aimed to evaluate improvement in the pain, motor, and sensory functions after neurosurgical intervention, by objective methods in patients with radiation-induced brachial plexopathy (RIBP), as a complication of radiotherapy (RT). Materials and Methods In our study, 11 patients, who experienced grade 3 or 4 brachial plexopathy according to the LENT-SOMA (late effects of normal tissue—subjective, objective, management, analytic) side-effect index, as a complication of RT which was performed after being operated for breast cancer, were included. In the postoperative period pain, sensation, and motor function loss were followed. Results There was apparent regression in the pain. The mean visual analogue scale (VAS) value decreased to 4 from the preoperative VAS value of 9.4. However, no significant improvement was observed in either sensory and motor functions. Conclusion RIBP is a progressive disease in breast cancer patients after radiotherapy. Evaluation of the results of applied surgical treatments and changes in the results with time is important to direct the treatment. Neurolysis should only be considered when other treatment methods fail and should be considered as an irreversible and potentially permanent procedure.
