Hipofrakcionált sztereotaktikus testsugárterápia és fluorouracil vagy kapecitabin zoledronsavval vagy anélkül lokálisan előrehaladott hasnyálmirigyrákos betegek kezelésében

2026. november 2. frissítette: University of Nebraska

Véletlenszerű II. fázisú vizsgálat a hipofrakcionált sztereotaktikus sugárterápia és az 5FU vagy kapecitabin hatásosságáról és biztonságosságáról Zometával és anélkül lokálisan előrehaladott hasnyálmirigy-adenokarcinómában szenvedő betegeknél

Pancreatic cancer, most commonly adenocarcinoma, is the fourth leading cause of cancer death in the United States. The mainstay of management centers on surgical resection (if resectable) and although low (15% to 20%), resectability rates are associated with dismal survival. An estimated 80% to 85% of the patients recur after surgical resection, leading to a median survival of 20 to 24 months and potentially even less depending on lymph nodal involvement or positive margins. The rationale for utilizing neoadjuvant therapy, commonly fluoropyrimidine-based or gemcitabine based chemotherapy or Chemoradiotherapy (CRT), involves possibly down staging borderline resectable and unresectable patients, potentially making them resectable candidates.

This randomized phase II trial will study how well hypofractionated stereotactic body radiation therapy (SBRT) and fluorouracil or capecitabine with or without zoledronic acid work in treating participants with pancreatic cancer that has spread to nearby tissue or lymph nodes. Hypofractionated stereotactic body radiation therapy is a specialized radiation therapy that sends higher doses of x-rays over a shorter period of time directly to the tumor using smaller doses over several days which may cause less damage to normal tissue. Drugs used in chemotherapy, such as fluorouracil and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Zoledronic acid is used in cancer patients to reduce cancer symptoms and may make tumor cells more sensitive to radiation. Giving hypofractionated stereotactic body radiation therapy and fluorouracil or capecitabine with or without zoledronic acid may work better in treating pancreatic cancer.

Pancreatic cancer, most commonly adenocarcinoma, is the fourth leading cause of cancer death in the United States. The mainstay of management centers on surgical resection (if resectable) and although low (15% to 20%), resectability rates are associated with dismal survival. An estimated 80% to 85% of the patients recur after surgical resection, leading to a median survival of 20 to 24 months and potentially even less depending on lymph nodal involvement or positive margins. The rationale for utilizing neoadjuvant therapy, commonly fluoropyrimidine-based or gemcitabine based chemotherapy or Chemoradiotherapy (CRT), involves possibly down staging borderline resectable and unresectable patients, potentially making them resectable candidates.

This randomized phase II trial will study how well hypofractionated stereotactic body radiation therapy (SBRT) and fluorouracil or capecitabine with or without zoledronic acid work in treating participants with pancreatic cancer that has spread to nearby tissue or lymph nodes. Hypofractionated stereotactic body radiation therapy is a specialized radiation therapy that sends higher doses of x-rays over a shorter period of time directly to the tumor using smaller doses over several days which may cause less damage to normal tissue. Drugs used in chemotherapy, such as fluorouracil and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Zoledronic acid is used in cancer patients to reduce cancer symptoms and may make tumor cells more sensitive to radiation. Giving hypofractionated stereotactic body radiation therapy and fluorouracil or capecitabine with or without zoledronic acid may work better in treating pancreatic cancer.

The primary study objective is to evaluate the efficacy of hypofractionated radiation therapy concurrently with zoledronic acid (Zometa) and fluorouracil or capecitabine. Other study objectives include examining the toxicity of Zometa when used concurrently with hypofractionated radiation therapy, evaluating local failure-free survival and overall survival, determining surgical resection and tumor response rates, measuring Zometa pharmacokinetics, evaluating tumor and organ motion and determining the effect those on the dosimetry, local control and survival. Post-treatment follow-up is for 30 days, then every 3 months for the first year, every 4 months for the second year, and every 6 months thereafter.

Időkeret
Local Control With and Without Zometa at Four Months in Follow-up
Időkeret: At 4 months in follow-up

Local control will be assessed using three-dimensional (3D) computed tomography (CT). The primary tumor will be contoured using Varian planning software, and tumor volume will be measured at baseline and at 4 months post-treatment. Local control is defined as absence of disease progression, with progression defined as a ≥25% increase in tumor volume. Tumor response will also be assessed using RECIST-based criteria (≥20% increase in tumor diameter) as a supportive analysis.
