- BACKGROUND
Mutations of c-MYC have been described in cervical cancer. However, association between c-MYC gene status and its prognostic significance have not been clarified.
METHODS
Tissue microarray sections from 144 patients with stage IB-IIB cervical cancer treated by radical hysterectomy were analyzed by fluorescence in situ hybridization using a region-specific probe for c-MYC and a centromere-specific probe for chromosome 8.
RESULTS
Seventy five percent (108/144) of c-MYC gain and 6.9% (10/144) of c-MYC gene amplification were observed.
c-MYC gene alteration was more frequently observed in squamous cell carcinoma than adenocarcinoma or adenosquamous carcinoma and were associated with low Ki67 labeling index (p=0.013). c-MYC amplification was not associated with clinicopathologic parameters except absence of bcl2 expression (p=0.048). Survival analysis revealed that patients with c-MYC amplification were significantly associated with higher risk of disease recurrence (p=0.007) and cancer related death (p=0.020). However, c-MYC gain was not associated with unfavorable outcome. Multivariate analysis proved c-MYC amplification as independent prognostic factors of shorter disease free survival and cancer-related death (p=0.028 and p=0.025, respectively).
CONCLUSIONS
c-MYC amplification, not gain, is an independent prognostic marker for shorter disease free and cancer specific survival in cervical cancer treated by radical hysterectomy.

Abstract

- BACKGROUND
Human papillomavirus (HPV) infection can be detected by in situ hybridization (ISH), in which a punctate signal pattern indicates integrated HPV DNA and a diffuse pattern denotes the presence of episomal viral DNA. This study was conducted to evaluate the usefulness of an HPV ISH assay for invasive cervical cancer.
METHODS
The HPV ISH assay for high-risk HPV and immunohistochemical staining for p16(INK4a), p53, bcl-2, and Ki-67 were performed in a tissue microarray of 279 cervical cancers.
RESULTS
High-risk HPV ISH was positive in 194 (69.5%) of the samples. Punctate, diffuse, and mixed signal patterns were observed in 157 (56.3%), one (0.4%), and 36 cases (12.9%), respectively. Positive results in high-risk HPV ISH were associated with p16 and bcl-2 expression (p = 0.01 and p < 0.01, respectively). According to a Cox regression analysis, HPV infection and its surrogate immunohistochemical markers such as p16, bcl-2, and Ki-67 were not independent prognostic factors, but stage and grade were independent prognostic factors.
CONCLUSIONS
Our results confirm that an HPV ISH assay is reasonably sensitive for HPV infection and that it might be useful to identify integrated HPV DNA in formalin-fixed and paraffin-embedded specimens. Further study encompassing HPV type, E2/E6 ratio, and therapeutic modality is necessary to understand the clinical meaning of HPV status in cervical cancer.
