Basal cell carcinoma with bone invasion: A systematic review and pooled survival analysis

BACKGROUND

Although basal cell carcinoma (BCC) tends to follow an indolent course, some tumors can exhibit locally aggressive behavior and invade into bone.

OBJECTIVE

To analyze all published demographic, clinical, and treatment data on recurrence patterns, disease progression, disease-specific death, and overall mortality of BCC with bone invasion.

METHODS

A systematic review and pooled-survival analysis was performed, including case reports and case series of BCC with bone invasion.

RESULTS

The study included 101 patients from 70 publications. BCC tumors invading into bone were most often large, neglected tumors located in high-risk face areas. At 5 years, patients had a 30% risk probability of disease recurrence (after negative margins), a 72.1% risk of disease progression or death (with ambiguous margin status), an 18.2% risk of BCC-related death, and a 20.7% overall probability of death.

LIMITATIONS

Limitations include the reliance on case reports and series for individual patient data, which has the potential to introduce selection bias.

CONCLUSION

The high rate of disease progression and suboptimal 5-year survival rate highlights the poor prognosis of BCC with bone invasion and further underscores the importance of early detection and treatment.
