ABSTRACT BACKGROUND.Although patients with locally advanced pancreatic cancer (LAPC) have an extremely poor prognosis, they are a heterogeneous group. Prognostic factors are inadequately defined for disease-free survival and overall survival in patients with LAPC who are receiving chemoradiation, so more definitive prognostic factors would be very useful for designing clinical trials.METHODS.Between December 1993 and July 2005, 247 patients with nonmetastatic LAPC were treated at M. D. Anderson Cancer Center (Houston, Tex) with concurrent chemoradiation (CRT). Median radiation dose was 30 Gy (range, 15–52.2 Gy). Radiosensitizers included 5-fluorouracil (54%), gemcitabine (33%), and capecitabine (13%). Actuarial univariate and multivariate statistical methods were used to determine significant prognostic factors for disease-free survival and overall survival.RESULTS.Median follow-up was 4.3 months (range, 1–63 months). Median disease-free survival and overall survival were 4.2 months and 8.5 months, respectively. On univariate analysis, prognostic factors for improved disease-free survival were a Karnofsky performance scale (KPS) status of >80 (P < .01) and a hemoglobin (Hgb)level at presentation of ≥12 (P = .03). On multivariate analysis, KPS was the only independent prognostic factor for disease-free survival. Median disease-free survival was 4.9 months among patients with a KPS score of >80 and was 3.9 months among those with a KPS score of ≤80. On univariate analysis, prognostic factors for improved overall survival were an Hgb level of ≥12 (P = .02), KPS>80 (P < .001), and <5% weight loss (P = .03). On multivariate analysis, Hgb and KPS were independent prognostic factors for overall survival.CONCLUSIONS.In the current study, KPS score was an independent prognostic factor for disease-free and overall survival among patients treated with chemoradiation for LAPC. The pretreatment Hgb level was an additional independent prognostic factor for overall survival. Cancer 2006. © 2006 American Cancer Society.

    ABSTRACT: Background: The goal of this retrospective study was to evaluate patient characteristics, treatment modalities and prognostic factors in Turkish patients with pancreatic cancer. Materials and Methods: Between January 1997 and December 2012, 64 patients who presented to the Department of Radiation Oncology, Karadeniz Technical University, Faculty of Medicine with a diagnosis of pancreatic cancer were evaluated. The E/K ratio of the cases was 2.4/1 and the median age was 59.6 (32-80) years, respectively. Some 11 cases (18%) were stage 1, 21 (34.4%) were stage 2, 10 (16.4%) were stage 3, and 19 (31.1%) were metastatic. Results: The mean follow-up time was 15.7 months (0.7-117.5) and loco-regional recurrence was noted in 11 (40.7%) who underwent surgery while metastases were observed in 41 patients (66.1%). The median overall survival (OS) was 11.2 months and the 1, 3 and 5-year OS rates were 41.7%, 9.9% and 7.9% respectively. The median disease-free survival (DFS) was 5.2 month and the1, 2 and 5 year DFS were 22.6%, 7.6% and 3.8% respectively. On univariate analysis, prognostic factors affecting OS included status of the operation (p<0.001), tumor stage (p=0.008), ECOG performance status (p=0.005) and CEA level (p=0.017).On multivariate analysis, prognostic factors affecting survival included status of the operation (p=0.033) and age (p= 0.023). Conclusions: In the current study, age and operation status were independent prognostic factors for overall survival with pancreatic patients. Thus, the patients early diagnosis and treatment ars essential. However, prospective studies with more patients are needed for confirmation.

    ABSTRACT: Platinum based doublets chemotherapy are the standard of care for metastatic or advanced non-small cell lung carcinoma. This leads to modest survival advantage and improve quality-of-life. However, patients with advanced or metastatic disease eventually present disease progression and needs second-line systemic therapy in a selected group of patients or other supportive measures. There is very little knowledge available from the literature about the prognostic variables in patients, who receive second-line therapy. We retrospectively reviewed 329 patients received second-line treatment from July 2007 to September 2011 in the Department of Radiation Oncology, Burdwan Medical College and Hospital. For statistical analysis, 12 potential prognostic variables included. Univariate and multivariate regression analysis carried out to identify the prognostic variables associated with survival. The results of univariate analysis for overall survival (OS) and survival after second-line therapy identified to have prognostic significance: Age, sex, performance status, smoking history, serum lactate dehydrogenase, histopathology, first-line chemotherapy and its response and second-line therapy except the stage at diagnosis and site of failure after first-line therapy. The multivariate Cox regression analysis has shown that only performance and second-line therapy were independent prognostic variables for survival after second-line treatment and above these prognostic factors; age, smoking status and progression free survival also for OS. The performance status has shown consistent result as a prognostic factor in univariate and multivariate analysis for OS and survival after second-line therapy. These findings may also facilitate pretreatment prediction of survival and be used for selecting patients for the correct choice of cytotoxic therapy.
