The limited effectiveness of chemotherapy in esophageal cancer used to palliate metastatic disease or to combine with radiotherapy in locally advanced disease has prompted the evaluation of new systemic agents. Irinotecan (CPT-11, Camptosar) has shown promising activity in a number of gastrointestinal cancers, including esophageal cancer. The phase II evaluation of the combination of weekly iri...

In prostate radiotherapy, the influence of bladder volume variation on the dose absorbed by the target volume and organs at risk is significant and difficult to predict. In addition, the resolution of a typical medical image is insufficient for visualizing the bladder wall, which makes it more difficult to precisely evaluate the dose to the bladder wall. This simulation study aimed to quantitat...

Radiotherapy has been the mainstay of treatment of stage III nonsmall cell lung cancer patients. In the early 90s, combined treatment with chemotherapy was introduced. In 1995, a meta-analysis showed improved treatment outcome of the sequential use of cisplatin-based chemotherapy and radiotherapy compared to radiotherapy alone. Subsequent randomized studies and two meta-analyses demonstrated th...

BACKGROUND Most of the cervical cancer patients, including those with cervical adenocarcinomas, come at advanced stage in the developing world so its mortality is high. Radiotherapy is one of the treatment modality for advanced stage cervical adenocarcinomas, but its efficacy depends on several prognostic factors such as the stage, histopathology, presence of organ dysfunction and expression of...

Endometrial cancer is a common female malignancy, affecting approximately 40,000 women per year. Despite the publication of several prospective randomized trials, there continues to be controversy regarding the use of adjuvant radiation therapy in endometrial cancer management. It is clear that most women with early-stage, low-risk disease will do well without adjuvant therapy. Intermediate-ris...

Endometrial cancer affects the uterus and is becoming increasingly common deadly. Although surgery adjuvant pelvic radiotherapy can often cure disease when it contained in uterus, patients with metastatic or recurrent have limited response rates to chemotherapy, targeted agents, hormonal therapy. To address this unmet clinical need, innovative treatment strategies are needed, a growing focus on...

UNLABELLED Targeted radiotherapy is a potentially useful treatment for some cancers and may be potentiated by bystander effects. However, without estimation of absorbed dose, it is difficult to compare the effects with conventional external radiation treatment. METHODS Using the Vynckier - Wambersie dose point kernel, a model for dose rate evaluation was created allowing for calculation of ab...

RATIONALE Chordomas are rare malignant neoplasms derived from incomplete regression of notochordal tissue along the cranio-coccygeal axis. Chordomas that develop in an atypical position are called ectopic chordomas, such as oropharyngeal chordomas (OCs). OCs are exceedingly rare; only 11 cases have been reported to date. Preoperative diagnosis is challenging, and an accurate diagnosis thus is b...

Abstract Background Whole brain radiotherapy (WBRT) is a common treatment option for metastases secondary to non-small cell lung cancer (NSCLC). Data from the QUARTZ trial suggest that WBRT can be omitted in selected patients and treated with optimal supportive care alone. Nevertheless, still widely used treat NSCLC. We analysed decision criteria influencing selection among European radiation o...
