Abstract

Post-operatif kemoradyoterapi, ameliyat edilen mide kanseri için terapötik yaklaşımlardan biridir. Radyoterapi planlaması sırasında şimdiye kadar pankreas kritik bir organ olarak kabul edilmemiştir, bu nedenle pankreas toksisitesi dikkate alınmamıştır. Prospektif çalışmamızda, radyoterapi sonrası serum pankreatik enzim düzeyleri ve pankreas hacmi araştırılmıştır. Adjuvan kemoradyoterapi uygu-lanan 71 mide kanserli hasta değerlendirildi. Ortalama pankreas hacmi, ortalama pankreas radyoterapi dozu ve V5, V10, V20 ve V40 değerleri hesaplandı. Açlık kan şekeri, insülin, amilaz ve glikolize hemoglobin düzeyleri radyoterapi öncesi değerlendirildi ve radyoterapi bitiminde, radyoterapiden sonra 1, 3, 6. ve 12. aylarda yeniden değerlendirildi. Pankreas hacmi radyoterapi öncesi değerlendirildi ve radyoterapiden sonraki 12. ayda yeniden değerlendirildi. Radyoterapi öncesi, radyoterapi bitiminde, radyoterapiden sonra 1, 3, 6. ve 12.aylarda serum açlık kan glikozu (p= 0.179), insülin (p= 0.296), HbA1c (p= 0.468) ve amilaz düzeyleri istatistiksel olarak anlamlı değildi (p= 0.069), ancak tedavi sonrası pankreas hacminde istatistiksel olarak anlamlı bir azalma vardı (p= 0.002). Postoperatif kemo-radyoterapi ameliyat edilen mide kanserli hastalarda sağkalımı uzatmakta ve rekürrensi azaltabilmektedir. Prospektif çalışmamızda, bir yıllık periyotta pankreas atrofisi haricinde pankreatik toksisite veya biyokimyasal parametreler üzerine istatistiksel olarak anlamlı bir bulgu tespit edemedik. Erken dönemde herhangi bir diabetes mellitus rapor edilmemesine rağmen, geç toksisite için takibi gereklidir.

Özet

Post-operative chemoradiotherapy is one of the therapeutic approaches for operated gastric cancer. During radiotherapy planning, pancreas has not been accepted as a critical organ until now, thus toxicity to pancreas has not been considered. In our pro-spective study, serum pancreatic enzyme levels and pancreatic volume after RT is investigated. Seventy-one patients with gas-tric cancer were evaluated adjuvant chemoradiotherapy. Mean pancreas volume, mean pancreas radiotherapy dose and V5, V10, V20 and V40 values were calculated. Fasting blood glucose, insulin, amylase and glycosylated hemoglobin levels were evaluated before radiotherapy and re-evaluated at the end of radiotherapy, at 1th, 3rd, 6th and 12th months after radiotherapy. Pancreas volume was evaluated before radiotherapy and re-evaluated at 12th month after radiotherapy. Before the initiation, after the first session and at the 1th, 3th, 6th and 12th months of radiotherapy, difference between serum Fasting blood glucose (p= 0.179), insulin (p= 0.296), HbA1c (p= 0.468) and amylase levels (p= 0.069) levels were not statistically significant but there is statis-tically significant decrease in pancreatic volume after treatment (p= 0.002). Postoperative chemoradiotherapy is able to prolong survival and decrease recurrence in operated gastric cancer patients. In our prospective study, we could not identify any statis-tically significant finding related to pancreatic toxicity or its presentation on biochemical parameters except pancreas atrophy in one-year period. Although, there was not any self-reported diabetes mellitus at early period it, follow-up needed for late toxicity.
