The aim of this study was to build a model to predict the survival benefit of radiotherapy for resected rhabdomyo-sarcoma at the individual level, to help clinicians and their patients make more informed decisions about adjuvant radiotherapy. Patients with resection of rhabdomyosarcoma between 1990 and 2010 were derived from the Surveillance, Epidemiology and End Results database. A multivariat...

The treatment of patients with malignant gliomas is palliative and encompasses surgery, radiotherapy, and chemotherapy. Outcome measures have demonstrated improvement in both survival and neurologic performance in patients undergoing complete or near-complete tumor resection. After surgery, involved-field radiotherapy (radiotherapy administered to the tumor and to the tissue in a 3-cm radius su...

OBJECTIVE Although surgical resection is used to treat meningeal hemangiopericytoma (MHPC), there is a high risk of subsequent recurrence. This study investigated factors associated with treatment outcomes and recurrence in patients who had undergone surgical resection of intracranial MHPC. METHODS Fifteen patients underwent surgical treatments performed by one senior neurosurgeon between 199...

Postoperative external beam radiotherapy was considered the standard adjuvant treatment for patients with glioblastoma multiforme until the advent of using the drug temozolomide (TMZ) in addition to radiotherapy. High-dose volume should be focal, minimizing whole brain irradiation. Modern imaging, using several magnetic resonance sequences, has improved the planning target volume definition. Th...

AIM To assess the relationship between the timing of radiotherapy and the risk of local failure in patients with endometrioid-type endometrial cancer who had undergone surgery and adjuvant external pelvic radiotherapy (with or without brachytherapy), but not chemotherapy. PATIENTS AND METHODS One hundred and seventy seven patients were analyzed in this study. The median follow-up of the survi...

Biochemical relapse after radical prostatectomy occurs in approximately 15-40% of patients within 5 years. Postoperative radiotherapy is the only curative treatment for these patients. After radical prostatectomy, two different strategies can be offered, adjuvant or salvage radiotherapy. Adjuvant radiotherapy is defined as treatment given directly after surgery in the presence of risk factors (...

High-level evidence supports adjuvant radiotherapy for rectal cancer. We examined the influence of sociodemographic factors on patterns of adjuvant radiotherapy for resected Stage II/III rectal cancer. Methods. Patients undergoing surgical resection for stage II/III rectal cancer were identified in SEER registry. Results. A total of 21,683 patients were identified. Majority of patients were mal...

Endometrial cancer generally has a good prognosis because most cases are diagnosed in stage I. It is possible to identify subgroups of patients with early stage endometrial cancer with a poor prognosis. Despite a traditional generous use of adjuvant radiotherapy those patients have less than an 80% 5-year overall survival. In this group there is a need for an effective systemic adjuvant therapy...

Background The aim of this study is to investigate the clinical results of adjuvant chemotherapy with hydroxyurea and to compare those with the results of postoperative radiotherapy after incomplete resection of atypical meningiomas (ATMNGs). Methods We retrospectively reviewed the medical records of 84 patients with ATMNGs diagnosed in the period from January 2000 to December 2014. Clinical ...

PURPOSE To discuss the outcomes of primary squamous cell carcinoma (SCC) of the major salivary glands treated by surgery with or without postoperative adjuvant radiotherapy. MATERIALS AND METHODS We performed a retrospective analysis of 579 cases with malignancy originating in the major salivary glands. A total of 34 cases were eligible for the present study. The outcomes were analyzed in ter...
