ABSTRACT
BACKGROUND: Synchronous occurrence of two malignant tumors is a rare event. With increasing use of sophisticated imaging modalities for staging, synchronous multiple tumors are more commonly detected now. Assuming the second primary malignancy as metastasis will change the intent of treatment from curative to palliative, greater awareness among oncologists is of paramount importance. This study is an example where thorough clinical examination and proper judgment resulted in correct diagnosis and appropriate treatment. MATERIALS AND METHODS: This is a prospective descriptive study. Patients diagnosed with synchronous primary tumors from January 2016 to November 2017 at our center were reviewed. RESULTS: Ten cases of synchronous primary malignancies were detected during this period. A total of 20 primary tumors were diagnosed. Lung carcinoma and gastrointestinal malignancies were the most common (five patients each). The median age was 59.5 years. Seven patients were male. Second primary tumor was suspected in four patients during clinical examination, while in six patients it was suspected on imaging. Even in the presence of two primary tumors, three patients were treated with curative intent. CONCLUSION: Possibility of synchronous second primary malignancy should always be kept whenever a distant deposit is detected at an unusual site. Histopathological evaluation of the lesion before assuming a metastasis will lead to accurate diagnosis, staging, and appropriate treatment.
ABSTRACT
The following is a commentary on the article “Arita I, Breman JG. Evaluation of smallpox vaccination policy. Bulletin of the World Health Organization. 1979;57(1):1-9.” Abstract (of the original article): During 1978 and 1979 the Global Commission for the Certification of Smallpox Eradication will proceed with verification of smallpox eradication in 31 countries. If current surveillance activities do not discover any further cases before the end of 1979, the world will be declared smallpox free. However, the recent occurrence of two laboratory associated smallpox cases in Birmingham, England, revealed that the stocks of variola virus held in at least 12 laboratories in the world pose a real danger to the achievement of smallpox eradication and efforts are being made to reduce the number of laboratories retaining the virus to not more than 4-all WHO collaborating centres-by 1980. Scientific data indicate the unlikelihood of smallpox recurring once it has been eradicated from the human population, although further confirmatory studies are continuing. If the Global Commission verifies the eradication of smallpox, continuation of smallpox vaccination will be unjus-tifiable in view of its severe complications, however infrequent, and the expected global savings that would result from the termination of vaccination programmes.
