AbstractRadiofrequency Ablation of subcapsular lesions poses a challenge due to the risks of tumour seeding along the track, hemorrhage and lower efficacy. “No touch ablation” is a relatively novel technique used in the ablation of subcapsular HCC with good results. This technique avoids direct puncture of the tumour by inserting more than one electrodes adjacent to and outside the tumor and activating them sequentially to perform ablation. The risk of track site seeding and haemorrhage is significantly reduced. We describe a case of a subcapsular HCC in a 65-year-old female patient which was successfully treated with this novel technique.

IntroductionAbdominal pain and distention are common in ovarian tumours. When the ovarian tumour grows too large, the tumour can cause these symptoms. Percutaneous drainage from ovarian tumours, which can alleviate symptoms, is traditionally discouraged for its potential risk of peritoneal tumour seeding.CaseA 73-year-old woman with a multilocular ovarian tumour reporting abdominal fullness and pain was referred to the palliative care outpatient department. The multilocular tumour occupied most of the intra-abdominal space, which was determined to cause her symptoms. To alleviate her symptoms, we performed intermittent percutaneous drainage for 1.5 years. A clinical autopsy revealed the tumour was an ovarian mucinous carcinoma. Despite iterative tumour drainage, we observed no feature of peritoneal dissemination.ConclusionIntermittent percutaneous drainage of ovarian tumours could reduce tumour-related abdominal symptoms without pathological evidence of peritoneal dissemination. This procedure can be a new palliative treatment option for ovarian tumour-related abdominal symptoms.

The role of percutaneous tumour biopsies had gain importance in the management of renal cell carcinoma to provide diagnostic specimen for the patients with metastatic disease that could benefit a systemic treatment. Among the possible complications of this procedure, however, there is the risk of tumoral cells seeding along the biopsy’s tract; this complication, albeit being reported as anecdotal, could have devastating effects. Here we report a case of a young male who developed subcutaneous chest metastasis of renal cell carcinoma after a biopsy of a lung nodule. We subsequently reviewed other cases reported in literature

Abstract Objectives Percutaneous liver biopsy (PLB) poses specific challenges in oncological patients such as bleeding and tumour seeding. This study’s aim was to compare a coaxial (C-PLB) and non-coaxial (NC-PLB) biopsy technique in terms of diagnostic yield, safety and seeding risk of image-guided PLB techniques in an oncological setting. Methods Local research committee approval was obtained for this single-site retrospective study. Patients who underwent a PLB between November 2011 and December 2017 were consecutively included. Medical records were reviewed to determine diagnostic yield and complications. Follow-up imaging was re-reviewed for seeding, defined as visible tumour deposits along the PLB track. Mann-Whitney U and chi-squared tests were performed to investigate differences between biopsy techniques in sample number, complications and seeding rate. Results In total, 741 patients (62 ± 13 years, 378 women) underwent 932 PLB (C-PLB 72.9% (679/932); NC-PLB 27.1% (253/932)). More tissue cores (p < 0.001) were obtained with C-PLB (median 4 cores; range 1–12) compared with NC-PLB (2 cores; range 1–4) and diagnostic yield was similar for both techniques (C-PLB 92.6% (629/679); NC-PLB 92.5% (234/253); p = 0.940). Complication rate (9.3%; 87/932) using C-PLB (8.2% (56/679)) was lower compared with NC-PLB (12.3% (31/253); p = 0.024). Major complications were uncommon (C-PLB 2.7% (18/679); NC-PLB 2.8% (7/253)); bleeding developed in 1.2% (11/932; C-PLB 1.2% (8/679); NC-PLB 1.2% (3/253)). Seeding was a rare event, occurring significantly less in C-PLB cases (C-PLB 1.3% (7/544); NC-PLB 3.1% (6/197); p = 0.021). Conclusions C-PLB allows for high diagnostic tissue yield with a lower complication and seeding rate than a NC-PLB and should be the preferred method in an oncological setting. Key Points • A coaxial percutaneous liver biopsy achieves a significant higher number of cores and fewer complications than a non-coaxial biopsy technique. • The risk of tumour seeding is very low and is significantly lower using the coaxial biopsy technique. • In this study, a larger number of cores (median = 4) could be safely acquired using the coaxial technique, providing sufficient material for advanced molecular analysis.

AbstractIntraperitoneal chemotherapy has shown promising results for the treatment of peritoneal carcinomatosis in gastric cancer. However, the implantation of an intraperitoneal chemotherapy port may be associated with catheter-related complications. The authors describe a case of cutaneous port-site recurrence secondary to tumour seeding from an intraperitoneal chemotherapy access port.
