Abstract

Colorectal cancer has an important place in worldwide death from cancer causes. Angiogenesis, in which angiogenic factors such as VEGF and basic FGF have a key role, is an important factor in patient survival with respect to progression and metastatic spreading in colorectal cancer. In this study, we aimed to determine whether serum VEGF and bFGF pre- and post-treatment serum levels are decisive in evaluating response to treatment and progression in metastatic colorectal cancer (mCRC) patients treated with FOLFIRI-bevacizumab. In 33 mCRC patients serum VEGF and bFGF levels were monitored at the beginning of treatment and until progression during FOLFIRIbevacizumab. In our study serum VEGF and bFGF levels were significantly higher than the healthy controls (p< 0.001). We found that the patients with pre-treatment high serum bFGF levels have significantly short Progression free survival. In patients with pre-treatment low serum VEGF value (< 147.79 pg/ml) had significantly longer overall survival (27.93 vs 23.27 months p:0.026) in metastatic rectum cancer. In multivariate analysis were found to be prognostic factors VEGF levels, response to treatment and side of the tumor for PFS and VEGF levels, response to treatment and whether to be operated of tumor for overall survival. Conclusions: Serum VEGF level was detected to be one of the factors that determine PFS and overall survival in mCRC. Pre-treatment serum bFGF levels were determined PFS and monitorization of serum bFGF during treatment was found to be related to response to treatment. Although there was no statistical significance, in mCRC patients, whose pre-treatment serum VEGF were high, PFS was longer with bevacizumab treatment. The importance of pretreatment high serum VEGF level to select for treatment of bevacizumab will be planned in metastatic CRC requires to be confirmed in comprehensive, prospective studies.

Özet

Kolorektal kanserin dünyadaki kanser nedenli ölümler içinde önemli bir yeri vardır. VEGF, bFGF gibi anjiojenik faktörlerin anahtar rol oynadığı anjiojenez, tümor progresyonu, metastatik yayılım ve hasta genel sağ kalımında önemli bir faktördür. Bu çalışmada; FOLFIRI-bevacizumab ile tedavi edilen metastatic kolorektal kanserli (mkrk) hastalarda; VEGF, bFGF ‘in tedavi öncesi ve sonrası düzeylerinin tedaviye yanıtı,ve hastalık progresyonunda ki yerini değerlendirmeyi amaçladık. Otuzüç mkrk’li olguda serum VEGF, bFGF düzeyi tedavi başlangıcı ve tedavi sürecinde monitörize edildi. Çalışmamızda hasta grubunda serum VEGF ve bFGF düzeyi sağlıklı kontrol grubuna oranla yüksek saptandı (p< 0.001) .Başlangıç bFGF düzeyi yüksek olan olgularda hastalıksız sağkalım anlamlı olarak kısa saptandı. Metastatik rektum kanserinde; başlangıç VEGF düzeyi düşük olan hastalarda (< 147.79 pg/ml) genel sağ kalım anlamlı olarak uzun bulundu (27.93vs 23.27 ay) .Multivariet analizinde; tüm sağ kalım için prognostic faktörler olarak; VEGF düzeyleri, tedavi yanıt, PFS ve VEGF için tümörün yeri, ve tümörün ameliyat edilip edilmediği olarak bulundu. MKRK’li olgularada tedavi öncesi serum VEGF düzeyi HSK ve GSK için önemli bir faktör olarak değerlendirildi. Tedavi öncesi serum bFGF düzeyleri belirlendi. Hastalıksız sağkalım ve tedavi sırasında serum bFGF düzeylerinin belirlenmesi tedaviye yanıt ile ilişkili bulundu.. Tedavi öncesi VEGF düzeyleri yüksek olan mkrk’lı hastalarda istatistiksel anlamlılık olmamasına rağmen bevacizumab tedavisiyle hastalıksız sağ kalım daha uzundu. MKRK’da Bevacizumab tedavisinin seçiminde ve planlamasında tedavi öncesi yüksek VEGF düzeyinin önemi, kapsamlı, prospektif çalışmalarla da onaylanmalıdır.
