Task: Answer Verification
Input (English): Question: Is intratumoral oxygenation of invasive squamous cell carcimoma of the vulva correlated with regional lymph node metastasis?
Answer: Although this analysis failed to demonstrate a strong correlation between various measures of tumour oxygenation with nodal metastasis, it may be due to the small number of patients. Only preoperative anaemia is correlated with nodal metastasis in early ISCC of the vulva.
Output (English): no
