    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, NS
    Background: 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.

    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, NS
    Adjuvant 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.

    Results of paclitaxel (day 1 and 8) and carboplatin given on every three weeks in advanced (stage III-IV) non-small cell lung cancer
    (BMC, 2005-12) YUMUK, PERRAN FULDEN; Yumuk, PF; Turhal, NS; Gumus, M; Hatabay, NF; Turken, O; Ozkan, A; Salepci, T; Aliustaoglu, M; Ahiskali, R
    Background: Both paclitaxel ( P) and carboplatin ( C) have significant activity in non-small cell lung cancer (NSCLC). The weekly administration of P is active, dose intense, and has a favorable toxicity profile. We retrospectively reviewed the data of 51 consecutive patients receiving C and day 1 and 8 P chemotherapy (CT) regimen in advanced stage NSCLC to evaluate the efficacy and toxicity. Methods: Patients treated in our institutions having pathologically proven NSCLC, no CNS metastases, adequate organ function and performance status (PS) ECOG 0-2 were given P 112.5 mg/m(2) intravenously (IV) over 1 hour on day 1 and 8, followed by C AUC 5 IV over 1 hour, repeated in every three weeks. PC was given for maximum of 6 cycles. Results: Median age was 58 ( age range 39-77) and 41 patients (80%) were male. PS was 0/1/2 in 29/17/5 patients and stage was IIIA/IIIB/IV in 3/14/34 patients respectively. The median number of cycles administered was 3 ( 1 6). Seven patients (14%) did not complete the first 3 cycles either due to death, progression, grade 3 hypersensitivity reactions to P or lost to follow up. Best evaluable response was partial response (PR) in 45% and stable disease (SD) in 18%. Twelve patients (24%) received local RT. Thirteen patients (25%) received 2nd line CT at progression. At a median follow-up of 7 months (range, 1-20), 25 (49%) patients died and 35 patients (69%) progressed. Median overall survival ( OS) was 11 +/- 2 months (95% CI; 6 to 16), 1-year OS ratio was 44%. Median time to progression (TTP) was 6 +/- 1 months (95% CI; 4 to 8), 1-year progression free survival (PFS) ratio was 20%. We observed following grade 3 toxicities: asthenia (10%), neuropathy (4%), anorexia (4%), anemia (4%), hypersensitivity to P (2%), nausea/vomiting (2%), diarrhea ( 2%) and neutropenia (2%). Two patients (4%) died of febrile neutropenia. Doses of CT were reduced or delayed in 12 patients (24%). Conclusions: P on day 1 and 8 and C every three weeks is practical and fairly well tolerated outpatient regimen. This regimen seems to be comparably active to regimens given once in every three weeks.
