Abstract

Background/aims: This study aimed to demonstrate the efficacy and tolerability of low-dose weekly gemcitabine as a radiosensitizer in unresectable pancreatic cancer patients treated with chemoradiotherapy. Methods: Twenty-four histologically confirmed pancreatic carcinoma patients (female/male: 10/14, median age: 60) were evaluated. Seven (29%) patients received gemcitabine either as a single agent or in combination prior to chemoradiotherapy. Concurrent 75 mg/m2 gemcitabine was infused weekly. Radiotherapy was delivered to the primary tumor and positive lymphatics with 3D-conformal radiotherapy to a total dose of 4500 cGy. Local progression-free survival, distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier method. Results: Median follow-up was 36 weeks. Median local progression-free survival, distant metastasis-free survival and overall survival were 22 weeks (95% confidence interval [CI]: 5-59 weeks), 19 weeks (95%CI: 6.9-31 weeks) and 36 weeks (95%CI: 28-43 weeks), respectively. All patients completed radiotherapy as scheduled. Concurrent gemcitabine was given fully in 58.3% of patients. Gemcitabine was terminated in four (16.6%) patients due to grade 3 neutropenia (n=1), grade 3 nausea/vomiting (n=2) or patient’s reluctance (n=1). Patients with local response and stable disease to chemoradiotherapy revealed a median survival of 39 weeks (95%CI: 30-47.9 weeks) compared to 36 weeks (95%CI: 9.7-62.2 weeks) in patients with locally progressive disease (p=0.52). Pain was improved in 50% of patients. Conclusions: Weekly low-dose radiosensitizing gemcitabine is effective and safe in unresectable pancreatic cancer patients.

Özet

Amaç: Bu çalışmada kemoradyoterapiyle tedavi edilen rezeke edilemeyen ve metastatik olmayan pankreas kanserinde radyosensitizan amaçlı düşük doz gemsitabininin, etkinliği ve tolerabilitesi araştırıldı. Yöntem: Histolojik olarak tanı konmuş 24 pankreas kanseri hastası (kadın/erkek: 10/14; ortanca yaş 60) değerlendirildi. Yedi (%29) hastada gemsitabin, tek başına ya da diğer ajanlarla birlikte indüksiyon amaçlı kullanılmıştı. Eş zamanlı gemsitabin 75 mg/m2 olarak haftalık uygulandı. Üç boyutlu konformal radyoterapi ile primer tümöre ve pozitif lenfatiklere 4500 cGy verildi. Lokal progresyonsuz sağkalım, uzak metastazsız sağkalım ve tüm sağkalım Kaplan-Meier metodu ile hesaplandı. Bulgular: Ortanca takip 36 hafta idi. Ortanca lokal progresyonsuz sağkalım, uzak metastazsız sağkalım ve tüm sağkalım sırasıyla 22 hafta (%95 GA 5-59 hafta), 19 hafta (9%5 GA 6.9-31 hafta) ve 36 hafta (%95 GA 28-43 hafta) idi. Bütün hastalar radyoterapiyi planlandığı dozda tamamladı. Eş zamanlı gemsitabin tam olarak %58.3 hastaya uygulandı. Gemsitabin dört (%16.6) hastada derece 3 nötropeni (n=1), derece 3 bulantı/kusma (n=2) ve hastanın reddi (n=1) nedeniyle kesildi. Kemoradyoterapi sonrası lokal tümörü cevap veren ya da stabil kalan hastalarda ortanca sağkalım 39 hafta (%95 GA 30-47.9 hafta) iken progresyon gösterenlerde 36 hafta (%95 GA 9.7-62.2 hafta) idi (p=0.52). Hastaların %50’sinde ağrı palyasyonu sağlandı. Sonuç: Rezeke edilemeyen pankreas kanserinde radyosensitizan haftalık düşük doz gemsitabin etkili ve güvenlidir.
