Abstract

The primary aim of this study was to evaluate the long-term treatment outcomes of definitive chemoradiotherapy (CRT) of locally advanced cervical cancer and beside this to identify prognostic factors and related toxicities. Between February 2001 and September 2013, 327 patients were retrospectively evaluated. The median age was 56 years (range, 24-82 years). Ninety-five percent of patients had ≥Stage IIB disease. External pelvic radiotherapy (RT) (45-50.4 Gy) and concomitant chemotherapy followed by 28 Gy in 4 fractions high dose rate brachytherapy was administered. Boost doses of 10-15 Gy were administered to <2 cm lymph nodes (LNs) or distal parametrial involved sites. The median follow-up time was 68 months (range, 45-90 months). Two-, 5- and 10-year cancer specific survival (CSS) rates were 80%, 68%, and 65%; disease-free survival (DFS) rates were 73%, 66%, and 64%; local recurrence-free survival (LRFS) rates were 94%, 92%, and 91%; loco-regional recurrence-free survival (LRRFS) were 92%, 89%, and 86%; distant metastases-free survival (DMFS) were 81%, 76%, 75%, respectively. In multivariate analysis, age, clinical stage and LN metastasis at diagnosis were independent prognostic factors for both CSS and DFS. Third month response to treatment was the most important prognostic factor for all end points in univariate and multivariate analysis. With the aggressive radiotherapeutic approach, it seems that distant metastases rather than locoregional recurrence determines the survival rates. Consolidation chemotherapy may be a good option after definitive CRT which needs to be supported with future phase III studies

Özet

Çalışmamızın primer amacı, lokal ileri evre serviks kanserlerinde definitif kemoradyoterapi (KRT) ile tedavinin uzun dönem sonuçlarının değerlendirilmesi ve bunun yanında ilişkili prognostik faktörlerin ve toksisite sonuçlarının tanımlanmasıdır. Şubat 2001 ve Eylül 2013 tarihleri arasında, 327 hasta dosyası retrospektif olarak incelenmiştir. Ortanca yaş 56 yıldır (aralık, 24-82 yıl). Hastaların %95'i >=evre IIB hastalığa sahiptir. Eksternal pelvik radyoterapi (RT) (45-50.4 Gy) ile eş zamanlı kemoterapiyi takiben 4 fraksiyonda 28 Gy yüksek doz hızlı brakiterapi uygulanmıştır. Distal parametriyal tutulum olan bölgeye ya da <2 cm lenf nodlarına (LN) 10-15 Gy ek doz verilmiştir. Ortanca izlem süresi 68 aydır (aralık, 45-90 ay). Sırasıyla 2-, 5- ve 10-yıllık kanser spesifik sağkalım (CSS) oranları %80, %68 ve %65; hastalıksız sağkalım oranları (DFS) %73, %66 ve %64; lokal rekürrenssiz sağkalım (LRFS) oranları %94, %92 ve %91; lokal-bölgesel rekürrenssiz sağkalım oranları (LRRFS) %92, %89 ve %86; uzak metastazsız sağkalım oranları (DMFS) %81, %76 ve %75'tir. Çok değişkenli analizde; yaş, klinik evre ve tanıda LN metastazı varlığı, CSS ve DFS için bağımsız prognostik faktör olarak bulunmuştur. Tek ve çok değişkenli analizde, 3. aydaki tedavi yanıtı tüm sonlanım noktaları için anlamlı prognostik faktör olarak saptanmıştır. Agresif RT yaklaşımına karşın, sağkalım oranlarını lokal-bölgesel rekürrensten çok uzak metastazların belirlediği görülmektedir. Definitif KRT sonrası konsolidasyon kemoterapisi, faz III çalışmalarla desteklenmesi gereken iyi bir seçenek olabilir
