Triple Malignancy: A Series of Three Cases

Abstract

Occurrence of Multiple Primary Malignancies (MPM) in an individual is an uncommon phenomenon. It can occur synchronously or metachronously, and the incidence ranges from 1 to 16%. There has been a dramatic increase in the incidence of multiple primaries in patients in the last few years. The diagnosis and treatment of these malignancies pose a clinical challenge as there is no consensus on the optimal management of this condition. It is important to distinguish this condition from the metastasis of an existing malignancy as it can alter the treatment and prognosis of these patients. So far, there have been few case reports published in the literature on triple malignancies, and to the best of authors knowledge, no series have been published yet. Here, authors report a series of three patients (one male and two females) who developed three primary malignancies either synchronously or metachronously. The management of all the patients was decided in a multidisciplinary board based on the stage of each disease and patient tolerance. Two of these patients are alive and on regular follow-up, while one patient was lost to followup during treatment. These cases highlight the importance of evaluating and closely following up patients, as well as considering histopathological examination of lesions in unusual sites of metastasis.
