These devices are typically placed in the subclavian or internal jugular vein and connected to a subcutaneous port. Following implantation, a chest X-ray is used to confirm catheter placement, detect early complications, and identify the \"pinch-off sign\"-a warning of potential catheter compression between the clavicle and first rib. Complications include malposition, pneumothorax, infection and catheter dysfunction such as pinch-off syndrome (POS), catheter fracture, and migration. POS can cause catheter dysfunction, fracture, and migration, potentially leading to severe cardiovascular or neurological complications, including cardiac perforation and pulmonary embolism. In some cases, catheter migration is asymptomatic and discovered incidentally. When catheter fragments migrate, removal via a percutaneous transvenous approach is preferred to avoid complications. However, in asymptomatic patients, observation may be a suitable alternative if the fragment adheres to the vessel. We report the case of a 25-year-old patient under surveillance for metastatic medullary thyroid carcinoma, whose catheter migrated to the pulmonary artery and remained complication-free for 6 years. This case highlights the importance of routinely checking for pinch-off syndrome whenever a central catheter is placed, and it suggests that removal of migrated catheter fragments may not be necessary in asymptomatic patients.</p>","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"12 1","pages":"uaaf056"},"PeriodicalIF":0.5,"publicationDate":"2025-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12812164/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146003540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment of peritoneal metastasis depends on several factors, including the type of primary cancer, the extent of metastasis and the patient's overall health condition. Apart from systemic chemotherapy and cytoreductive surgery (CRS), locoregional therapies such as hyperthermic intraperitoneal chemotherapy (HIPEC) or pressurized intraperitoneal aerosol chemotherapy (PIPAC) may improve tumour control. CRS is a complex procedure with high morbidity, performed only in approximately 25% of all eligible patients and the efficiency of other non-surgical therapies is not well known. The place of radiation therapy needs to be defined. A 62-year-old woman was referred for surgery for a few days' history of large bowel obstruction. A previous abdominopelvic CT showed an obstructive 3-cm mass in the proximal ascending colon, associated with small bowel dilatation. Right hemi-colectomy was performed. Work-up demonstrated on MRI (magnetic resonance imaging) sub-centimetric secondary liver lesions. ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) ruled out other metastatic lesions. After multidisciplinary discussion, peri-operative systemic therapy based on FOLFOX-Bevacizumab was offered and was associated with stable disease for 7 months. Unfortunately, peritoneal progression was detected on PET/CT imaging. FOLFIRI-Bevacizumab was offered as second line systemic therapy followed by resection of residual masses. The patient was considered in remission for 5 months thereafter. A second isolated peritoneal relapse occurred involving the same 2 distinct sites. Second line chemotherapy was re-challenged. The oligorecurrent PM lesions were considered as non-operable. After multidisciplinary team discussion, stereotactic body radiation therapy (SBRT) was decided. The relapse sites were treated with 48 Gy, delivered in 6 fractions of 8 Gy given every other day. At the 22-month follow-up, the patient showed no signs of relapse on CT imaging and no treatment-related toxicities. Isolated peritoneal oligometastatic metastases are associated with poor prognosis. Cytoreductive surgery remains the historical standard of care treatment but represents a minority of all eligible patients. Our case and few other reports suggest that SBRT is a safe, reasonable, and non-invasive treatment option.</p>","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"11 6","pages":"uaaf060"},"PeriodicalIF":0.5,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12718100/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145805725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An 85-year-old woman was recommended to undergo surgery for locally advanced uterine sarcoma of unknown histological subtype, but she refused because of her poor physical and social circumstances. She instead received chemotherapy; however, the lesion progressed, and the patient opted for best supportive care. Palliative radiation therapy was indicated for genital bleeding. She thereafter received the QUAD shot regimen, in which 3.7 Gy was administered twice a day for 2 consecutive days and repeated every 4 weeks for a total dose of 44.4 Gy in 3 cycles. The lesion significantly decreased in size, and no new regional or distant metastases were identified. Although only palliative radiation therapy was initially intended, the favourable response with no new lesion development prompted us to offer additional brachytherapy for curative intent, and the patient accepted. She underwent 2 sessions of uterine cervical intracavitary and interstitial brachytherapy using a gel spacer, and local control of the lesion was achieved at 1-year and 3 months follow-up of treatment without major adverse events.
