췌장선암의 치료에서 정위체부방사선치료와 화학요법 후 수술 중 방사선치료
국소 췌장선암 치료에서 정위체부방사선치료와 다제제 화학요법에 따른 수술 중 방사선치료의 안전성 연구
This study is designed to investigate the safety of intraoperative radiation therapy (IORT) in patients with localized pancreatic cancer undergoing surgical resection after neoadjuvant chemotherapy and stereotactic body radiation therapy (SBRT).

상태
정황
상세 설명
Standard of care treatment for patients with non-metastatic pancreatic adenocarcinoma (PDAC) includes chemotherapy and Stereotactic Body Radiation Treatment (SBRT) followed by surgical resection of the tumor with or without Intra-Operative Radiation Therapy (IORT).
There is some evidence from other research studies suggesting that adding radiation treatment during the surgical resection may improve local control of the cancer. The use of IORT plus surgical resection can be used to treat pancreatic cancer and is done on a case by case basis at Johns Hopkins.
The department of Radiation Oncology has developed a program using a High Dose Rate-IORT (HDR-IORT). The HDR-IORT makes it possible to deliver concentrated radiation dose at the surface of the tumor.
Our team has shown in previous studies that the majority of cancer cells that remain after treatment are located around the area of the pancreas called the "Triangle Volume" (TV). This region contains blood vessels, lymphatic vessels, and nerves, and is at high risk of containing cancer cells. This region is difficult to treat with SBRT alone because of being close to normal, healthy organs. Therefore, this study involves using IORT to treat the TV to a therapeutic radiation dose.
The part of the treatment that is considered research is:
- Giving one dose of 15 Gy during the surgery using IORT to deliver radiation, and
- Targeting the larger area around the pancreas called the TV
The goal of this study is to determine safety of this added treatment which will be assessed at 3 months after the surgery is completed.

다른: Intra Operative Radiation Therapy (IORT) Group
The IORT group is the single arm of this study. Enrolled patients who undergo standard of care treatment will also receive a study treatment of High Dose Rate (HDR) Intra Operative Radiation Therapy. |
After the patient receives standard of care treatment, they will receive a single dose of radiation (15 Gy) at the time the tumor is surgically removed. Surgeons will then place clips along the blood vessels around the surgical area. These clips will be used to confirm (after surgery) that the expected dose of radiation was received during surgery. |
