BACKGROUND: The present study aims at determining whether there is a statistically significant difference in postoperative survival time after VATS talc pleurodesis for palliative treatment of MPEs with VATS surgical methods - conventional and single-port, as well as revealing whether the histological variation of the primary tumor is a determining factor for postoperative survival time.
METHODS: Total 147 patients with MPEs were treated at the Clinic of Thoracic Surgery. Of all 147 patients 117 underwent VATS talc pleurodesis. Survival analysis was performed by the Kaplan-Meier method. The test for comparing the equality of the survival distributions between the study groups was done by use of the Mantel-Cox Log Rank.
RESULTS: For conventional VATS talc pleurodesis the Mean Survival Time was estimated at 8.170 months with SEM 1.305. Median Survival Time was estimated at 4.133 months with standard error of Mean (SEM) of 0.731. For single-port VATS talc pleurodesis Mean Survival Time was estimated at 14.849 months with SEM of 4.965. Median Survival Time was estimated at 2.900 months with standard error of 0.907.
CONCLUSIONS: Histologically different variants of primary tumor after VATS talc pleurodesis cannot be interpreted as a statistically significant factor for survival (P>0.05). Histologically different types of the pulmonary carcinoma can be interpreted as a statistically significant factor for survival after VATS talc pleurodesis for treating MPE (P<0.05).
