    Abstract The main aim of this paper is to give the definitions of Caputo fractional derivative operators and show their use in the special function theory. For this purpose, we introduce new types of incomplete hypergeometric functions and obtain their integral representations. Furthermore, we define incomplete Caputo fractional derivative operators and show that the images of some elementary functions under the action of incomplete Caputo fractional operators give a new type of incomplete hypergeometric functions. This definition helps us to obtain linear and bilinear generating relations for the new type incomplete Gauss hypergeometric functions

    Purpose: Small bowel adenocarcinoma (SBA) is a rare tumor of the gastrointestinal system with poor prognosis. Since these are rarely encountered tumors, there are limited numbers of studies investigating systemic treatment in advanced SBA. The purpose of this study was to evaluate the prognostic factors and systemic treatments in patients with advance SBA

    BackgroundCombination of gemcitabine and nab-paclitaxel has superior clinical efficacy than gemcitabine alone. Nevertheless, health-related quality of life. (QoL) associated with this combination therapy when administered at first-line in advanced pancreatic adenocarcinoma is unknown.MethodsA total of 125 patients were randomized to combination therapy (1000mg/m2 gemcitabine +125mg/m2 nab-paclitaxel) and single-agent gemcitabine (1000mg/m2) arms to take treatment weekly for 7 of 8weeks, and following 3 of 4weeks, until progression or severe toxicity. Primary endpoints were three-months of definitive deterioration free percent of patients, and QoL.ResultsOverall QoL analyses showed that 34 and 58.3% of cases in gemcitabine and gemcitabine+nab-P arms had no deterioration in 3rd month QoL scores (p=0.018). These proportions were 27.3 and 36.6% in 6(th) month assessments, respectively (p=0.357). Median overall survivals in combination and single-agent arms were 9.92months and 5.95months, respectively (HR: 0.64, 95% CI: 0.42-0.86, p=0.038). Median progression free survivals in these treatment arms were 6.28 and 3.22months, respectively (HR: 0.58, 95% CI: 0.39-0.87, p=0.008). Median time-to-deterioration were 5.36 vs 3.68months, and objective response rates were 37.1% vs 23.7% (p=0.009), respectively in combination and single-agent arms.ConclusionsCombination therapy with gemcitabine + nab-paclitaxel had better overall and progression-free survival than gemcitabine alone. Also, combination therapy showed increased response rate without toxicity or deteriorated QoL. Combination treatment with gemcitabine and nab-paclitaxel may provide significant benefit for advanced pancreatic cancer.Trial registrationThis study has been registered in ClinicalTrials.gov as NCT03807999 on January 8, 2019 (retrospectively registered)
