Abstract
INTRODUCTION: Osseous metastasis in gynaecological epithelial tumours is an extremely rare phenomenon occurring in less than 1% of these cancers. AIM: To analyse the clinical characteristics and prognosis in patients with gynaecological epithelial cancers with bone metastases. MATERIALS AND METHODS: This was a single institutional retrospective study done with the data available from January 2008 to January 2015. Out of 1686 patients with epithelial gynaecological malignancies there were a total 18 (1.07%) patients with osseous metastasis. Clinico-pathologic characteristics were tabulated in Microsoft Excel 2013 and data were analysed using SPSS software Version 21. A p-value< 0.05 was taken to be statistically significant. Survival analysis was done by using Kaplan-Meier method and log-rank test was used to find out the difference in survivals. RESULTS: Out of the 18 gynaecological epithelial cancer patients with bone metastases, 12 had cervical cancer, three had ovarian cancer, two had endometrial carcinoma and one patient had vulvar malignancy. Twelve patients had squamous cell histology, while the rest had adenocarcinoma. The mean interval from primary diagnosis of cancer to the detection of bone metastases was 31.9 months (range, 1 - 60 months). Solitary bone lesion was present in seven patients. The most common site of bone metastasis was lumbar vertebra. Extra-osseous metastasis was present in 12 patients. The mean follow-up period was 8.3 months. During the follow-up period 12 out of the 18 patients died. There was significant difference in survival (p = 0.005) between patients with solitary bone metastasis and patients with multiple osseous metastases. Near significant survival difference (p = 0.056) was also noted in patients with extra-osseous metastases when compared to the patients without. Improved survival was also found in patients with controlled local disease (p = 0.003) when compared to patients with local failure. CONCLUSION: Bone metastasis in gynaecological epithelial malignancies is a rare phenomenon, but with grave prognosis. Multiple sites of bone involvement, recurrence at the primary tumour site and presence of other non-osseous metastases are poor prognostic indicators. Treatment in these patients should be tailored according to the patient's need.
