Six of the twenty two patients, however, are alive and 16 had median survival of 15 months with median tumor-free interval of 14 months.
In 20 of the twenty two treated with repeated or bilateral thoracotomies, there was a correlation between decrease number of metastatic lesions with number of thoracotomies and survival.
Wedge excision performed repeatedly produced only minimal loss of vital capacity, compared with lobectomy.
Dn bloc resection of pericardium, chest wall, and diaphragm enhanced no survival.
The patients with tumor-free interval of greater than 8 months survived or succumbed to the disease and was associated with mitotic ratio of more than 10 or less.
Both of chest X-ray and CT scan had a positive diagnostic rate of 41 % and 67%, respectively.
Currently, we conclude that modified Thomfold’s indication is applicable to the patient with pulmonary metastatic osteosarcoma with bilateral or multiple nodules and more than 8 months of tumorfree interval.
