Factors of influence upon the SF-36-based health related quality of life of patients following surgery for petroclival and lateral posterior surface of pyramid meningiomas.

OBJECTIVE

To describe the patient's self assessed health related quality of life (saHRQoL) based upon the medical outcome study 36-item short form health survey (SF-36) as well as the factors of influence upon the saHRQoL following surgery for petroclival (PCM) and lateral posterior surface of the pyramid (LPPM) meningiomas.

PATIENTS AND METHODS

In a series of 78 patients operated consecutively for PCM (n = 46) or LPPM (n = 32) the preoperative, intraoperative and postoperative data were collected retrospectively. The saHRQoL was obtained by mailing the SF-36 questionnaire to the patients. The SF-36 data of the whole patients group was compared with a healthy population. The SF-36 data of the PCM- and LPPM were compared to each other. The influence of pre-, intra- and postoperative findings upon the SF-36 was assessed by uni- and multifactorial analysis.

RESULTS

58 (69%) out of the 78 patients answered the SF-36 questionnaire at a median postoperative follow-up of 59 months. The patients, who answered the SF-36 questionnaire, had a significant lower perioperative complication rate than those who did not (46% vs. 75%, p = 0.019). The saHRQoL of the LPPM and PCM was reduced on several sub-scales, when compared to the German reference population. The outcome of PCM is, assessed by saHRQoL as well as by conventional neurosurgical grading scales, inferior to that of LPPM. The saHRQoL of LPPM correlated in the uni- and multivariate analysis with the early postoperative KPI on the sub-scales SF1 (physical functioning) and SF5 (vitality). Accordingly, the sub-scale SF2 (role-physical) of PCM correlated with the change of the KPI from preoperative to the last follow up.

CONCLUSIONS

The saHRQoL of the evaluable patients was lower than that of the normal population. The saHRQoL score of PCM-patients was lower than that of LPPM-patients. For the future the saHRQol should be assessed routinely; It reflects the patients' perspective upon postoperative outcome and enables the comparison with other treatment modalities of these difficult to treat tumors.
