Modified simultaneous integrated boost radiotherapy for large retroperitoneal malignant tumor: A case report.

The current study reports the case of a large retroperitoneal tumor treated with modified simultaneous integrated boost (SIB) radiotherapy. A 45-year-old female presented to the emergency department complaining of left abdominal pain and fever. A computed tomography scan detected a retroperitoneal tumor of 12×16×16 cm, and a biopsy revealed a poorly-differentiated adenocarcinoma.

Modified simultaneous integrated boost radiotherapy for an unresectable huge refractory pelvic tumor diagnosed as a rectal adenocarcinoma.

A clinical trial of radiotherapy with modified simultaneous integrated boost (SIB) technique against huge tumors was conducted. A 58-year-old male patient who had a huge pelvic tumor diagnosed as a rectal adenocarcinoma due to familial adenomatous polyposis was enrolled in this trial. The total dose of 77 Gy (equivalent dose in 2 Gy/fraction) and 64.

Modified simultaneous integrated boost radiotherapy for unresectable locally advanced breast cancer: preliminary results of a prospective clinical trial.

Background: The purpose of this study was to evaluate the effect of modified simultaneous integrated boost (SIB) radiotherapy for patients with extensive breast cancer.

Patients And Methods: Patients with macroscopic tumor and histologically proven adenocarcinoma of the breast were enrolled in the study. Patients were included whether they had or did not have previous surgery, chemotherapy, hormone therapy, or molecular targeted therapy; patients with past history of thoracic radiotherapy were excluded.

Relationship between serum reactive oxidative metabolite level and skin reaction in an irradiated rat model.

Purpose: Ionizing radiation generates free radicals and reactive oxygen species that induce DNA damage in vivo. This study aimed to determine the relationship between serum reactive oxygen metabolite (ROM) levels and skin reaction after irradiation in a rat model.

Methods And Materials: I.

Radiotherapy for inoperable and refractory endometriosis presenting with massive hemorrhage: a case report.

Introduction: Many patients with endometriosis are treated with medication or by surgical approaches. However, a small number of patients do not respond to medication and are inoperable because of comorbidities. This case report shows the effectiveness of radiotherapy for refractory endometriosis and includes a time series of serum estradiol levels.

A phase I trial of S-1 with concurrent radiotherapy in patients with locally recurrent rectal cancer.

Background: The purpose of this phase I trial of S-1 chemotherapy in combination with pelvic radiotherapy for locally recurrent rectal cancer was to determine the maximum tolerated dose (MTD), recommended dose (RD), and dose-limiting toxicity (DLT) of S-1.

Methods: We enrolled 9 patients between April 2005 and March 2009. Radiotherapy (total dose, 60 Gy in 30 fractions) was given to the gross local recurrent tumor and pelvic nodal metastases using three-dimensional radiotherapy planning.
