abstract
Background: Paraaortic lymph nodes represent the second level in the lymphatic spread of cervical cancer.
Recent studies have confirmed the association of HPV DNA in pelvic lymph nodes in early-stage disease
with metastatic involvement and a less favourable prognosis.
Objective: The aim of our study was to detect 13 high-risk genotypes of HPV in paraaortic nodes harvested
from patients with FIGO IB2–IIIB tumours and correlate findings with histopathology.
Study design: The study involved patients with advanced cervical cancer who had undergone low paraaor-
tic lymphadenectomy. The cytobrush technique was used for perioperative sample collection from the
tumour and fresh lymphatic tissue. Patients with non-HPV related cancers were used as a control group.
Results: The study involved 24 cervical cancer patients. High-risk HPV DNA was found in the primary
tumour of all cases and in PALN in 16 (67%) cases. The most frequent genotype was HPV 16, both in
the tumour and in the paraaortic lymph nodes (83% and 54%, respectively). Metastatic involvement of
paraaortic lymph nodes was identified in 8 cases (33%), which all were also HPV DNA positive. No HPV
DNA was detected in PALN in any of 22 control group cases.
Conclusions: Using the cytobrush technique, the presence of at least one HR HPV genotype in the primary
tumour was identified in all the patients. The metastatically involved paraaortic lymph nodes always
contained the DNA of at least one HPV genotype present in the primary tumour. Determination of clinical
significance of HR HPV DNA presence in histologically negative lymph nodes requires further follow-up
of the cohort.

1. Background
Almost all cases of cervical cancer are caused by human papil-
lomavirus (HPV) infection. One of the most important prognostic
factors in cervical cancer patients is the metastatic involvement
of the lymph nodes which, depending on the stage of the dis-
ease, shortens the five-year survival rate by 25–60%.

Even when
lymph nodes are negative, a part of the surgically treated patients
suffer from relapse of the disease.

One possible cause of retroperi-
toneal relapses may be the presence of subclinical metastatic lymph
node involvement. There have been several references in literature
of high-risk (HR) HPV DNA presence in lymph nodes as a pos-
sible marker of such subclinical involvement. Recent prospective

studies have confirmed the simultaneous presence of HPV DNA in
metastatically involved pelvic lymph nodes.

Paraaortic lymph nodes (PALN) represent the second level in the
lymphatic spread of cervical cancer. Their metastatic involvement
has been documented in about 25% of locally advanced stages.

Clinical staging of the PALN is a decisive parameter for the deter-
mination of the extent of the radiation field.

2. Objectives
No study has so far evaluated prevalence and significance of HR
HPV DNA presence in the PALN in patients with advanced cervical
cancer. It was the aim of our study to detect 13 HR genotypes of
HPV in PALN harvested from patients with FIGO IB2–IIIB tumours
and correlate findings with histology. The control group consisted
of patients with non-HPV related tumours (ovarian or endometrial
cancer).
