Abstract

ÖZET
Amaç: Yakın zamanda metastatik kolon kanseri üzerinde yapılan çalışmaların geriye dönük verilerine dayanarak,
primer tümör lokalizasyonunun sağ kalımı ve kemoterapi (KT) yanıtını etkileyen bir faktör olduğu
görülmüştür. Bu çalışmaların çoğunda metastatik halde tanı alan hastalar dahil edilmiştir. Çalışmamızda tanı
anında erken evrede olan, cerrahi ve veya adjuvan tedaviler sonrası nükseden hastalarda primer tümörün
lokalizasyonunun önemi olup olmadığı incelendi.
Hastalar ve Metod: Tıbbi Onkoloji kliniğince 2013 ile 2017 yılları arasında kolorektal kanser tanısıyla takip
edilmiş, tanı anında Evre II ve Evre III olup sonrasında metastaz gelişen 79 hasta çalışmaya dahil edildi. Hastalar
primer tümörün lokalizasyonuna göre, sağ ve sol olarak iki gruba ayırıldı. Hastaların demografik verileri
sağkalım süreleri primer tümör lokalizasyonuna göre karşılaştırıldı.
Bulgular: Toplam 79 hastanın ortalama yaşları sağ ve sol grupta sırasıyla 60 ve 59 yıl olarak benzerken (P =
0.965), demografik verilere bakıldığında iki grup arasında sağ kolonda Tip2 diabetes mellitus (Tip2DM) görülme
oranının yüksekliği (sırasıyla %34.5 ve %4.4, P = 0.002) haricinde anlamlı fark saptanmadı. Neoadjuvan
KT sol gurupta ve nodal tutulum varlığı ise sağ tarafta yüksek saptansa da fark istatistiksel olarak anlamlı
değildi. Yine her iki gurup arasında adjuvan KT almış olma, adjuvan KT ve palyatif KT rejimleri arasında fark
saptanmadı. Sağkalım analizinde, sağ ve sol guruplar arasında progresyonsuz sağkalım (PS) ve toplam sağkalım
(TS) oranları benzerdi [PS sırasıyla 11.9 (6-17.9) ay’a karşı 16.7 (13.1-20.4) ay, P = 0.976 ve TS sırasıyla
36.1 (14.6-57) ay’a karşı 40.8 (35.3-46) ay, P = 0.636].
Sonuç: Çalışmamızda tanı anında metastatik olmayan bu hasta gurubunda, primer tümör lokalizasyonunun
sağ kalım üzerine etkili bir faktör olmadığı saptandı. Bu durum, cerrahi, neoadjuvan ve adjuvant tedavilerin
etkinliklerinin, primer tümör lokalizasyonunun önemini gölgelediğini düşündürmektedir.

ABSTRA
Objective: Based on retrospective data from previous studies on metastatic colon cancer, it has recently
been found that primary tumor localization is a factor affecting survival and response to chemotherapy (CT).
Most of these studies included de-novo metastatic patients. In this study, investigation indicated that whether
primary tumor localization was helpful in patients relapsed after surgical and-or adjuvant treatment
rather than metastatic at the time of diagnosis.
Patients and Methods: A total of 79 patients with stage II and stage III metastatic colorectal cancer disease
whom diagnosed in the Department of Medical Oncology, between 2013 and 2017, were included in the
study. Patients were divided into two groups according to localization of the primary tumor as right and
left. Demographic data of the patients were compared with survival time according to primary tumor
localization.
Findings: The mean ages of 79 patients were similar in the right and left groups (59 vs 60 years, P = 0.965).
According to demographic features, there were no significant differences was found between the two
groups except for the high incidence of Type2 diabetes mellitus (T2DM) in right-sided (34.5% and 4.4%, P =
0.002, respectively). Neoadjuvant CT in the left group and nodal involvement in the right side were higher,
however not statistically significant. Again, there was no difference between the two groups in terms of
receiving adjuvant CT, regimens of adjuvant CT and palliative CT. Survival analysis showed that the PS and TS
ratios were similar between the right and left groups [PS was 11.9 (6-17.9) months versus 16.7 (13.1-20.4)
months, P = 0.976 and TS, respectively, 36.1 (14.6-57) months 40.8 (35.3-46) months, P = 0.636].
Conclusion: According to results of our study, it was determined that primary tumor localization was not
an important factor on survival in patients with early colorectal cancer. This suggests that the efficacy of
surgery, neoadjuvant, and adjuvant treatments may be more important than primary tumor localization.
