Stereotactic body radiation therapy in patients with hepatocellular carcinoma: A mini-review

引用

World Journal of Gastrointestinal oncology 2019年第5期11卷 367-376页

作者： Sabine Gerum Alexandra D Jensen Falk Roeder department of radiation oncology University Hospital LMU Munich department of radiation oncology University Hospital Gie?en and Marburg CCU Molecular radiation oncology German Cancer Research Center department of Radiotherapy and radiation oncology Paracelsus Medical University

Stereotactic body radiation therapy(SBRT) is an emerging treatment for hepatocellular carcinoma. This technique results in excellent local control rates with favorable toxicity profile despite being predominantly used in heavily pretreated patients or those unsuitable for other local therapies. SBRT may be used as a sole treatment or in combination with other local therapies as well as a bridging strategy for patient awaiting liver transplants. This brief review describes current practice of SBRT with respect to radiation technique, patient selection and treatment concepts. It summarizes available evidence from retroand prospective studies evaluating SBRT alone, SBRT in combination with other treatments and SBRT compared to other local treatment approaches.

Proton therapy for pancreatic cancer

引用

World Journal of Gastrointestinal oncology 2015年第9期7卷 141-147页

作者： Romaine C Nichols Soon Huh Zuofeng Li Michael Rutenberg department of radiation oncology University of Florida

Radiotherapy is commonly offered to patients with pancreatic malignancies although its ultimate utility is compromised since the pancreas is surrounded by exquisitely radiosensitive normal tissues, such as the duodenum, stomach, jejunum, liver, and kidneys. Proton radiotherapy can be used to create dose distributions that conform to tumor targets with significant normal tissue sparing. Because of this, protons appear to represent a superior modality for radiotherapy delivery to patients with unresectable tumors and those receiving postoperative radiotherapy. A particularly exciting opportunity for protons also exists for patients with resectable and marginally resectable disease. In this paper, we review the current literature on proton therapy for pancreatic cancer and discuss scenarios wherein the improvement in the therapeutic index with protons may have the potential to change the management paradigm for this malignancy.

Technical advances in external radiotherapy for hepatocellular carcinoma

引用

World Journal of Gastroenterology 2016年第32期22卷 7311-7321页

作者： Shin-Hyung Park Jae-Chul Kim Min Kyu Kang department of radiation oncology Kyungpook National University Hospital department of radiation oncology Kyungpook National University School of Medicine

Radiotherapy techniques have substantially improved in the last two decades. After the introduction of 3-dimensional conformal radiotherapy, radiotherapy has been increasingly used for the treatment of hepatocellular carcinoma(HCC). Currently, more advanced techniques, including intensity-modulated radiotherapy(IMRT), stereotactic ablative body radiotherapy(SABR), and charged particle therapy, are used for the treatment of HCC. IMRT can escalate the tumor dose while sparing the normal tissue even though the tumor is large or located near critical organs. SABR can deliver a very high radiation dose to small HCCs in a few fractions, leading to high local control rates of 84%-100%. Various advanced imaging modalities are used for radiotherapy planning and delivery to improve the precision of radiotherapy. These advanced techniques enable the delivery of high dose radiotherapy for early to advanced HCCs without increasing the radiation-induced toxicities. However, as there have been no effective tools for the prediction of the response to radiotherapy or recurrences within or outside the radiation field, future studies should focus on selecting the patients who will benefit from radiotherapy.
