Recent advancements in cancer treatment have increased the incidence of secondary tumors and metachronous tumors by means of improving survival rates. Increased risk of secondary cancer is observed after radiotherapy and chemotherapy episodes. It is a clinical observation to now encounter recurrences many years after a successful treatment or a primary resection of a tumor. How a tumor cell persists alive but stable and how it demonstrates its tumorigenic potential remain to be clarified. A patient with colon adenocarcinoma and coexisting malignant melanoma who presented synchronic metastasis in the follow-up is presented in this manuscript.

Metakron tümörde senkron metastaz: Olgu sunumu

Öz

Son zamanlarda kanser tedavisindeki ilerlemeler hastaların kanserden kür olmalarını sağlayarak sağkalım süreçlerini artırdığı için ikinci tümör, metakron tümör görülme insidansında da artışa neden olmuştur. İkincil kanser risk artışı, radyoterapi, kemoterapi veya kombine tedaviler sonrasında gözlenmiştir. Başarılı bir tedavi ya da primer tümörün başarıyla çıkarılmasından yıllar sonra nüks görülmesi sık bir klinik gözlemdir. Tümör hücresinin sabit ancak canlı kalması ve daha sonraki bir zamanda tümörojenik potansiyelini göstermesi hala açıklanamamış bir konudur. Yazımızda kolon adenokarsinom karaciğer metastazı ve malign melanom tanısı ile izlenen, takibinde senkron metastaz saptanan olgu sunuldu.
