Vulval Cancer Multiple Choice Questions for Vol. 17, No. 4 Chapter 1: Dhar and Woolas 1.
Historically, in the management of vulval cancer: a. Early concepts in management included en bloc radical resection of the vulva and a bilateral inguinofemoral node dissection. b. Pelvic lymph node dissection was advised. c. Early studies indicated that the draining lymphatics from the vulva crossed the labio-crural folds. d. Prior to 1988, the FIGO staging of vulval cancer was independent of surgicalhistopathological features. e. Lesion size, and perineal location of the cancer are relevant in the current FIGO staging.
2.
Important developments in newer approaches to treatment included: a. Recognition that wound problems following the butterfly incision were related, in part, to compromising basic surgical principles. b. In most vulval cancers spread to the groin nodes was embolic such that a skin bridge between the vulva and groins could be preserved. c. Pelvic node resection should only be performed when the groin nodes contained metastatic disease. d. Squamous cell cancer of the vulva of less than 2 cm diameter rarely had lymph node metastases. e. Vulval cancers that were truly lateral, did not have contralateral node metastases.
3.
In vulval cancer management: a. Imaging of primary vulval cancer and the groin nodes by CT or MRI is an important assessment prior to definitive treatment. b. Compared to lateral vulval cancer, central disease, is more likely to require multi-modal therapy. c. Exenterative surgery continues to have a place in surgical management. d. Multifocal disease is common in younger patients with vulval cancer. e. Centralisation of care with involvement of the multi-disciplinary team (MDT) is standard of care.
