RECOMMENDATIONS

MAJOR RECOMMENDATIONS

The recommendations that follow are those from the guideline's executive summary; detailed recommendations can be found in the original guideline document. Each recommendation is rated based on the level of the evidence and the grades of recommendation. Definitions of the grades of the recommendations (A, B, C, Good Practice Points) and level of the evidence (Level I-Level IV) are presented at the end of the Major Recommendations field.

Screening

B - To reduce the incidence and mortality rate of cervix cancer, effective screening and preventive strategy must be actively pursued, in addition to early detection of disease and effective therapy (Anderson et al., 1995; Laara, Day, & Hakama, 1987). (Grade B, Level IIa)

Stage IA

B - Total hysterectomy is the treatment of choice for microinvasive cervical cancer in patients who have completed their family. In selected patients, fertility-sparing surgery may be considered. (Grade B, Level III)

Stage IB – IIA

A - Current evidence indicates that both radical surgery and pelvic radiotherapy result in equivalent cure rates for early localized cervical cancer (Landoni et al., 1997). (Grade A, Level Ib)

A - The addition of post-operative treatment using a combination of chemotherapy and radiotherapy has been shown to improve survival outcome for patients with tumour involvement of pelvic lymph nodes, resection margins, and/or parametrial tissue (Sedlis et al., 1999; Peters et al., 2000). (Grade A, Level Ib)

The optimal treatment for bulky (>4cm) cervical cancer remains controversial.

Stage IIB – IVA

A - The treatment of choice for locally advanced cervical cancer is concurrent chemoradiation. (Grade A, Level Ia)

Metastatic Cancer

B - The main aim of treatment for patients with metastatic cancer is palliation of symptoms. (Grade B, Level IIa)

Recurrent Cancer

B - The treatment employed for patients with recurrent cervical cancer is dependent on their previous treatment modality and the exact anatomical site of relapse. (Grade B, Level IIa)

Ovarian Conservation

B - Ovarian conservation should be considered for young patients (Sutton et al., 1992). (Grade B, Level IIa)

Hormone Replacement Therapy

B - There is no clinical evidence that Hormone Replacement Therapy should be withheld from patients with a history of cervical cancer (Gadducci et al., 1997; Burger et al., 1999; Ploch, 1987; Sadan et al., 1989; Wren, 1994). (Grade B, Level IIa)

Definitions:

Grade C (evidence level IV): Requires evidence obtained from expert committee reports or opinions and/or clinical experiences of respected authorities. Indicates absence of directly applicable clinical studies of good quality.

Good Practice Points: Recommended best practice based on the clinical experience of the guideline development group.

Levels of Evidence

BENEFITS/HARMS OF IMPLEMENTING THE GUIDELINE RECOMMENDATIONS

POTENTIAL BENEFITS

Overall Benefits

  • Guideline implementation may help reduce the incidence and mortality of cervical cancer and improve cure rates and survival rates.
  • Cervical cancer screening will allow doctors to detect pre-invasive disease and early-stage cervical cancer, both of which carry a good prognosis.
  • Well-run population-based cervical cancer screening programmes with good coverage can reduce the incidence and mortality of cervical cancer.

Specific Benefits

  • The addition of concurrent weekly intravenous platinum-based chemotherapy, up to a total of 6 cycles, has been found to improve survival outcome in three randomised studies, in particular for patients without extra-pelvic nodal involvement.
  • Current evidence indicates that both radical surgery and pelvic radiotherapy result in equivalent cure rates for early localized cervical cancer.
  • The addition of post-operative treatment using a combination of chemotherapy and radiotherapy has been shown to improve survival outcome for patients with tumour involvement of pelvic lymph nodes, resection margins, and/ or parametrial tissue.

POTENTIAL HARMS

  • Side effects/complications of treatment
  • False-negative Pap-smear results, even in women who have regular screening

CONTRAINDICATIONS

CONTRAINDICATIONS

Contraindications for Chemotherapy

  • Poor patient performance status
  • Advanced age
  • Inadequate bone marrow and renal function

QUALIFYING STATEMENTS

QUALIFYING STATEMENTS

  • These guidelines are not intended to serve as a standard of medical care. Standards of medical care are determined on the basis of all clinical data available for an individual case and are subject to change as scientific knowledge advances and patterns of care evolve.
  • The contents of the guideline document are guidelines to clinical practice, based on the best available evidence at the time of development. Adherence to these guidelines may not ensure a successful outcome in every case, nor should they be construed as including all proper methods of care or excluding other acceptable methods of care. Each physician is ultimately responsible for the management of his/her unique patient in the light of the clinical data presented by the patient and the diagnostic and treatment options available.
  • This set of management guidelines covers the majority, and common aspects, of cervical cancer but is not meant to be exhaustive. Where situation necessitates, the treatment of a patient must be tailored to the individual.

IMPLEMENTATION OF THE GUIDELINE

DESCRIPTION OF IMPLEMENTATION STRATEGY

Clinical Audit

  • All patients treated for cervical cancer must have histopathological confirmation before commencement of treatment.
  • The diagnosis of microinvasive disease of the cervix requires a single large cone biopsy with clear margins.
  • All patients must be assigned a clinical stage based on recognized criteria and investigative procedures set out in the main guidelines.
  • The reasons for deviation from these practice guidelines must be documented.
