OBJECTIVES: Soft tissue metastasis (STM) is an uncommon condition in carcinoma. Although various case series related to STM have been reported, few reports have examined prognostic factors. This study aimed to evaluate the characteristics of STM and the factors affecting its prognosis. MATERIALS AND METHODS: Patients with STM from carcinoma were retrospectively studied. The patients' information, including age, sex, primary tumor, metastasis location, size of the metastatic tumor, presence of pain, histological classification, history of primary tumor treatment, and other metastasis at diagnosis of STM were collected and associated with prognosis. RESULTS: Overall, 16 patients with a mean age of 68.7 years were evaluated. The overall survival rate was not significantly different between lung cancer and non-lung cancer patients. The overall survival rate was significantly better in patients undergoing definitive treatment for the primary tumor than in those without history of treatment (p = 0.046). The overall survival rate of STM patients with no metastasis was significantly better than those with other metastasis at the diagnosis of STM (p = 0.041). On multivariate analysis, no history of primary tumor treatment and STM without pain were risk factors for prognosis (p = 0.0340 and 0.0474, respectively). None of the patients who developed STM under the skin experienced pain, while 92.3% of the patients who developed STM in the deep layer had pain. CONCLUSION: The risk factors for poor diagnosis of STM were no past treatment of the primary tumor and absence of pain. STM in the deep layer is prone to pain.
