Abstract

Introduction: Cancers of the vulva are relatively rare and, therefore, little is known about the pathophysiological role of tumor oxygenation in this entity. Methods: Data are presented on the oxygenation status of primary (n = 15) and recurrent (n = 19) cancers of the vulva, as mea­sured by the Eppendorf pO2, histography system. Results: Contrary to other tumor entities, no significant differences in the oxygenation status between primary (median pO2 = 13 mmHg; hypoxic fraction ≤5 mmHg = 37%) and recurrent (median pO2 = 11 mmHg; hypoxic fraction ≤5 mmHg = 45%) tumors were found. Oxygenation was significantly lower in cancers of the vulva than in the subcutis. Anemic patients had significantly poorer tumor oxygenation compared with patients whose cHb values were within the normal range (p = 0.02). Conclusions: The oxygenation of vulvar cancers is similar to other tumor entities, but does not show more severe hypoxia in recurrent cases. Anemia is associated with a poorer oxygenation status in vulvar cancers, whereas in the normal tissue no impact of cHb values on the median pO2 was observed.
