Publication Open Access Concurrent chemoradiotherapy with low dose weekly gemcitabine in stage III non-small cell lung cancer(BMC, 2005-12) YUMUK, PERRAN FULDEN; Abacioglu, U; Yumuk, PF; Caglar, H; Sengoz, M; Turhal, NSBackground: Combined chemoradiotherapy (CRT) is the treatment of choice for stage III NSCLC. Gemcitabine (G) is a novel deoxycitidine analogue that has been proven to be a potent radiosensitizer. Twenty-two consecutive patients were treated with concurrent CRT to demonstrate the tolerability and efficacy of low dose G given weekly as radiosensitizer in stage III NSCLC. Methods: Patients with KPS >= 70, adequate bone marrow reserve, with no prior radiotherapy (RT) and surgery were included. Eighteen patients had received prior induction chemotherapy (CT). G (75 mg/m(2)/week) was infused over 1 hour for 6 weeks. Thoracic RT was given two hours later over 6 weeks at 1.8 Gy/day fractions (total dose of 61.2 Gy). Pulmonary toxicity was evaluated with computed tomography scans in 6 weeks. Results: Median age was 60 years (range, 48-75), median follow-up was 15 months (range, 2-40). Sixty-eight percent of patients were male and median KPS score was 90. Conformal 3D-RT planning was used in 64% of patients. G was given for a median of 5 weeks ( range 1-9). Twelve patients (54.6%) received all planned CT. G was stopped because of intolerance in 6 and death in 2 patients. Seven patients (31.8%) had radiation pneumonitis. Twenty patients were evaluated for overall response, 1 patient (4.5%) had clinical CR, 81.8% had PR while 9.5% had SD. Median overall survival (OS) was 14 +/- 5 months (95% CI 3-25). One- and 2-year OS rates were 55% and 38%. Sixteen patients died of disease-related events (6 with progression of primary tumor, 8 due to metastatic disease), 2 patients died of other causes. One- and 2-year progression- free survival and local control rates were 56%, 27% and 79%, 51%, respectively. Conclusion: G might be used as radiosensitizer for patients with stage III NSCLC who could not receive full doses CT with concurrent RT.Publication Metadata only Limited painful mouth opening(W B SAUNDERS CO, 2005) YUMUK, PERRAN FULDEN; Guler, N; Yumuk, PF; Ilguy, D; Gac, V; Greer, JPublication Metadata only Outcome of rectal and sigmoid carcinoma patients receiving adjuvant chemoradiotherapy in marmara university hospital(TAYLOR & FRANCIS LTD, 2003) YUMUK, PERRAN FULDEN; Yumuk, PF; Abacioglu, U; Caglar, H; Gumus, M; Sengoz, M; Turhal, NSAdjuvant chemoradiotherapy is the standard treatment in resected stage II/III rectosigmoid carcinoma. We report a retrospective analysis of 33 patients who received adjuvant chemoradiotherapy. Patients received 5-fluorouracil (375mg/m(2)/day x 5days) and calcium leucovorin (20mg/m(2)/day x 5days), q4weeks, two courses before and two courses after radiotherapy. The 5-fluorouracil dose was reduced to 225mg/m(2)/day given continuously as protracted short-term infusion on the first and last 3 days during radiotherapy. Radiotherapy was started at 7th week and 45-50.4 Gy was given to pelvic region. Median age was 63 years. Median follow-up was 38 months starting from the operation date. Four-year local and distant control rates were 78% and 69%, respectively. Four-year disease-free survival and overall survival were 60% and 62%, respectively. Protracted short-term infusion of 5-fluorouracil during pelvic irradiation is a safe treatment modality. Further studies are needed to improve the local control of high-risk rectal and sigmoid carcinomas.
