The literature on transplacental cancer transmission is sparse, consisting mainly of case reports, small cohort studies, and reviews. Examples of cancers that have been transmitted in this way include melanoma, choriocarcinoma, leukaemia, and lymphoma. Understanding this phenomenon is important because it has direct clinical implications for managing pregnant women with cancer and the infant, raises questions about the placental barrier and immune interactions between mother and fetus, and offers insights that could influence cancer biology and treatment strategies. This review aims to evaluate existing data, identify and synthesize evidence on transplacental cancer transmission cases, evaluate cancer types involved, their transmission mechanisms, and clinical outcomes for both mothers and infants. A comprehensive electronic search of databases was conducted for relevant case reports and series, using specific keywords related to vertical and transplacental transmission of cancer.

In both Cases 2, 3, the surgeon used a curved vascular clamp to bluntly separate and fully expose the pelvic part of the ureter and then coagulated and divided the vessels. The separation started when the ureter traced the base of the posterior lobe of the broad ligament until it entered below the uterine artery. The uterine artery dissection site differed in Cases 2 and 3, with Case 2 being at the origin of the internal iliac artery and Case 3 in an area close to the CF, depending on the space between the CF and uterine artery.
