Editor,
We read the article by Sharma et al. "Evaluation of central nervous system metastases with immunohistochemistry correlation" with interest. [1] In this regard we would like to share our experience from a tertiary care center. We had encounered 40 central nervous system metastatic tumors in our study period. Most common primary was lung in our study as reported by the authors. There were 10 cerebellar metastatic adenocarcinomas unlike that reported in literature. With our limited available immunohistochemical panels, we were not able to detect primary in 12 cases. In these cases the routine chest X-ray did not detect any abnormality. [2] There were a couple of cases of metastatic melanoma in our study group unlike the authors. We had a single case of metastatic carcinoma of breast this we attribute to the fact that in developing countries females with advanced malignancy rarely come forward for treatment.
We are of the opinion that a thorough history, good morphological assessment, relevant investigations and judicious use of immunohistochemistry can help to detect the primary tumor. In Indian subcontinent delayed presentation of the patients, poor financial condition and lack of follow-up are major obstacles in detecting the primary tumor, establishing diagnosis as well as in rendering treatment.
As rightly pointed out by Saha, a long-term follow-up study with survival analysis and assessment of Karnofsky performance status should be carried out to predict prognosis and to select appropriate therapeutic protocol. [3]
