RESUMO

RATIONALE: Transcatheter arterial chemoembolization (TACE) is a widely adopted treatment for advanced stage hepatocellular carcinoma (HCC). Nevertheless, several complications may occur, such as hepatic artery injury, nontarget embolization, pulmonary embolism, hepatic abscess, biloma, biliary strictures, and hepatic failure. However, bronchobiliary fistula is rarely mentioned before. PATIENT CONCERNS: A 65-year-old man with HCC underwent the TACE procedure, and then he encountered fever, dyspnea, abdominal pain, and abundant yellowish purulent bronchorrhea. DIAGNOSIS: Bronchobiliary fistula was diagnosed based on the computed tomography (CT) scan of his chest, which revealed the right lower lobe of his lung was connected to a hepatic cystic lesion. INTERVENTIONS: Percutaneous transhepatic cystic drainage was performed, and we obtained yellowish bile, showing the same characteristics as the patient's bronchorrhea. OUTCOMES: We kept drainage of his biloma and provided supportive care as the patient wished. Unfortunately, the patient passed away due to progressive right lower lobe pneumonia 2 weeks later. LESSONS: This case exhibits a typical CT scan image that was helpful for the diagnosis of post-TACE bronchobiliary fistula. Post-TACE bronchobiliary fistula formation hypothesis includes biliary tree injuries with subsequent biloma formation and diaphragmatic injuries. Moreover, the treatment of bronchobiliary fistula should be prompt to cease pneumonia progression. Therefore, we introduce this rare complication of post-TACE bronchobiliary fistula in hopes that future clinicians will keep earlier intervention in mind.

RESUMO

Breast cancer is the most common diagnosed malignancy in women. This study genotyped blood samples from 236 Han Chinese women with breast cancer and 128 healthy controls for single nucleotide polymorphisms (SNPs) rs2977537, rs2929970, rs2929973, rs2977530, and rs62514004, to determine whether these WNT1-inducible signaling pathway protein 1 (WISP-1) genetic polymorphisms increase the risk of developing breast cancer. Compared with wild-type (AA) carriers, those carrying the WISP1 rs62514004 AG or AG + GG genetic variants had a greater risk of developing breast cancer. In an evaluation of the association between clinicopathological aspects and the WISP1 SNP rs62514004 in the breast cancer cohort, patients with the GG genotype were less likely than those with the AA genotype to develop stage III/IV disease. Patients carrying the WISP1 rs2929973 GG + TT variant were almost twice as likely as those carrying the GT genotype to have estrogen receptor (ER)- and progesterone receptor (PR)-positive tumors, while those with the WISP1 rs62514004 AG + GG genetic variants were around twice as likely as those with the AA genotype to have HER2-positive tumors. This study details risk associations between WISP1 SNPs and breast cancer susceptibility in women of Han Chinese ethnicity.
