“…The authors reported only one complication of a rectus sheath haematoma. A second earlier study by the same institution [10] involved 35 female patients, 31 of whom had CT-guided biopsy using an 18-gauge cutting needle. The authors reported a high accuracy rate of 92%.…”

“…There have been few publications on the use of imageguided percutaneous biopsy to determine management in advanced ovarian carcinoma [9][10][11], with most studies describing results of computed tomography (CT)-guided percutaneous biopsy in patients with peritoneal carcinomatosis. The aims of the current study are: (1) to report the accuracy of image-guided percutaneous biopsy in patients with suspected ovarian cancer prior to start of neo-adjuvant chemotherapy; (2) to evaluate if large-gauge (14-16 swg) biopsy needles are as safe as small-gauge (18-20 swg) needles, and (3) to compare the accuracy and safety of USguided biopsy with CT-guided biopsy.…”

Image-guided biopsy in patients with suspected ovarian carcinoma: a safe and effective technique?

In patients with suspected advanced ovarian carcinoma, a precise histological diagnosis is required before commencing neo-adjuvant chemotherapy. This study aims to determine the diagnostic accuracy and complication rate of percutaneous biopsies performed under ultrasound or computed tomography guidance. Between 2002 to 2007, 60 consecutive image-guided percutaneous biopsies were performed in patients with suspected ovarian cancer. The following variables were recorded: tissue biopsied, imaging technique, experience of operator, biopsy needle gauge, number of passes, complications, and final histology. Forty-seven patients had omental biopsies, 12 pelvic mass biopsies, and 1 para-aortic lymph node biopsy. Thirty-five biopsies were performed under ultrasound, 25 under computed tomography guidance. Biopsy needle gauges ranged from 14-20 swg with two to five passes for each patient. There were no complications. Histology was obtained in 52 (87%) patients. Percutaneous image-guided biopsy of peritoneal disease or pelvic mass is safe with high diagnostic accuracy. The large-gauge biopsy needle is as safe as the small gauge needle, but has the added value of obtaining tissue samples for immunohistochemistry and genomic studies.

“…However, the immunohistochemical marker profi le was unlike that of primary peritoneal cancer. 15 Therefore, ectopic peritoneal mesothelium was probably not the origin of the carcinoma. Because S-1 has been used effectively in the treatment of pancreatic, gastric, or colorectal cancer, we gave S-1 as an adjuvant chemotherapy agent to this patient based on the aforementioned immunohistochemical fi ndings.…”

Adenocarcinoma in an intrapancreatic accessory spleen: Report of a case

et al. 2011

We report a case of adenocarcinoma in an intrapancreatic accessory spleen (IPAS). A 78-year-old woman presented with abdominal discomfort, and investigations revealed an elevated serum carbohydrate antigen 19-9 level, to 161.8 U/ml (normal, <37 U/ml). Ultrasonography showed a heterogeneous echogenic tumor with a vascular hilum. Computed tomography showed a heterogeneously enhanced tumor, 8 cm in diameter, adjacent to the pancreatic body, accompanying a feeding artery arising from the splenic artery, and a drainage vein flowing into the splenic vein. We performed a distal pancreaticosplenectomy. The tumor was surrounded by a fibrous capsule and was in contact with the pancreatic body. Histological examinations revealed invasive growth of adenocarcinoma in a structure identical to the spleen. The results of both radiological and histological examinations suggested that the tumor originated from an intrapancreatic accessory spleen. Extensive examinations revealed no other malignancy, based on which we concluded that the adenocarcinoma was primary. Surgical intervention is strongly recommended when a malignancy in an IPAS cannot be ruled out.

“…14 In patients with indeterminate clinical and radiological findings of benign and malignant peritoneal masses, imageguided peritoneal core biopsy can be safely done for determining the tumor type. 20 In recent published papers, color Doppler US has been reported to be useful in differentiating malignancies from benign tumors and predicting and assessing the chemotherapy response of tumors. Quantitative flow parameters, RI and PI, measured from tumor vessels were compared in benign and malignant conditions.…”

Peritoneal Carcinomatosis: Image-guided Peritoneal Core Biopsy for Tumor Type and Patient Care

Abstract: Image-guided peritoneal core biopsy with hematoxylin-eosin analysis supplemented with immunohistochemical analysis is a simple, safe, and accurate technique for providing site-specific diagnoses in women with undiagnosed peritoneal carcinomatosis.
