WHO Referral Guidelines for Breast and Cervical Cancers in LMICs

 

The draft referral guidelines were based upon a review of evidence that had been prepared by a committee charged with assisting the WHO Guidelines Development Group to ensure that recommendations are based on the available evidence. Immediate referral of cases with clinical characteristics consistent with the possibility of cancer to higher level of care facilities is fundamental to a strategy for early detection and diagnosis and should translate into better treatment outcomes for patients at lower cost. Evidence-based guidelines for referral of patients with suspected cancer at the PHC level have so far not been developed by WHO or by any LMIC.

 

Discussions were held about the methodology used by WHO to develop referral guidelines. One issue that arose was that the evidence provided upon which to base the guidelines was almost exclusively risk factors for the development of the disease. However, it is the clinical features that determine referral - the symptoms noted by the patient or signs noted by the doctors. It was agreed that risk factors have little or no influence on referral, although they may alter the likelihood that a given sign is caused by cancer.

 

On the second day, Drs Sankaranarayanan, Sepulveda and Magrath continued with the development of the guidelines and held a teleconference with the advisory committee to discuss the guidelines. A relatively small number of revisions to the draft were required and there was considerable agreement among the committee members about signs and symptoms that could lead to a diagnosis of breast or cervical cancer. The modified guidelines are presently undergoing final editing and should be ready for publication early next year.
