Synchronous and metachronous malignancies: analysis of the Minneapolis Veterans Affairs (VA) tumor registry

Abstract: Multiple primary malignancies are a growing area of interest in cancer survivorship. At our institution, approximately 1 in 9 new cancer diagnoses during the 5-year study period represented second-order malignancies. Our data suggest that the VA population is at risk of developing second primary cancers. Further analysis of this population to identify unique risk factors is warranted.

“…The field cancerization effect of tobacco has been suggested as the reason for this predilection, but the authors were not able to explain why it is more frequently seen with synchronous than with metachronous malignancies [17,18]. While our patient fits into the profile mentioned by them, the other two cases of synchronous presentation did not fit this profile as they did not involve the aerodigestive tract.…”

“…Деление ПМЗН на синхронные (период между их обнаружением ≤6 мес) и метахронные (период меж-ду их обнаружением >6 мес) принято для удобства изу-чения канцерогенеза при ПМЗН. Синхронные ЗН составляют около 25 % в структуре ПМЗН [4]. В их случае высока вероятность того, что организм больного подвергся действию единого внешнего или внутреннего фактора риска, что послужило тол-чком к развитию сразу нескольких опухолей.…”

“…Yine aynı şekilde multifokal üst üriner THK'sinin de mesane kanserinin ortaya çıkışında bağımsız bir risk faktörü olduğu iddia edilmiştir (57). Bir çalışmada mesane kanserinin sekonder tümörleri istatistiksel olarak anlamlı olmak üzere senkron tümörler lehine (%21,8 senkron, %10,8 metakron tümör) bildirilmiştir (8). Yine aynı çalışmada mesane ve üreter kanserleri birlikte değerlendirildiğinde en sık prostat (%7,3) ve akciğer kanseri (%2) birlikteliği bildirilmiştir (8).…”

“…Metakron tümörler daha ziyade önceki kanser tedavilerinin bir sonucu olarak gelişirken, senkron tümörler sigara ve alkol gibi organ spesifik karsinojenlerle ilişkilidir. Bu nedenle senkron tümörler sıklıkla sigara ile ilişkili olarak aerodigestif (baş-boyun, akciğer ve üst özogafus) ve üriner sistemi tutma eğilimindedir (8). Sekonder tümör gelişme riskini artıran kemoterapötik tedavilerden özellikle alkalen ajanlar en sık yassı hücreli kansere neden olurken, radyoterapi her tip kanser sıklığını artırabilmektedir (9).…”
