The variety of treatment options for cancer patients has increased significantly in recent years. Not only do we combine radiation with surgery and chemotherapy, new therapeutic approaches such as immunotherapy and targeted therapies are starting to play a bigger role. Physics has made significant contributions to radiation therapy treatment planning and delivery. In particular, treatment plan ...

Thoracic irradiation historically plays a strong role in the management of non-small cell lung cancer (NSCLC). Though surgery is the mainstay of early-stage (I and II) disease, adjuvant radiation therapy confers better local control than surgery alone in advanced disease (III). Combining chemotherapy with radiation can help decrease systemic tumor burden and confer an overall survival advantage...

Background: Quantification of radiation-induced apoptosis in peripheral blood lymphocytes (PBLs) has been proposed as a possible screening test for cancer-prone individuals and also for the prediction of normal tissue responses after radiotherapy. Materials and Methods: The neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation ...

PURPOSE To evaluate the efficacy of radiation in patients treated with neoadjuvant chemotherapy and mastectomy. PATIENTS AND METHODS We retrospectively analyzed the outcomes of 542 patients treated on six consecutive institutional prospective trials with neoadjuvant chemotherapy, mastectomy, and radiation. These data were compared to those of 134 patients who received similar treatment in the...

UNLABELLED Increasing the intensity of radiation therapy and chemotherapy in the management of cancer has increased the incidence of adverse effects, especially oral mucositis. AIM AND METHODS a bibliographical review was conducted on the definition of oral mucositis, its clinical findings, the incidence, its etiology, the pathophysiology, associated morbidity, prevention and treatment. RES...

Surgery and/or radiation were historically standard of care in locally advanced head and neck malignancies. During the 1980s, various radiation schedules were studied. Chemotherapy was eventually added to radiotherapy, first sequentially, as induction chemotherapy, then concurrently, recognizing the primary need of improved locoregional control over that of distant disease control. Simultaneous...

To report on a suspected case of idiopathic radiation recall dermatitis in an individual nine months after radiation and chemotherapy treatment of squamous cell carcinoma of the right tonsil. Radiation recall dermatitis is the development of a reaction in a previously irradiated area of skin after the administration of an aggravating medication. A review of the literature revealed several cases...

angiogenesis, the process of new blood vessel formation from existing ones, plays an important role in  the physiologic circumstances such as embryonic development, placenta formation, and wound healing. it is also crucial to progress of pathogenic processes of a variety of disorders, including tumor growth and metastasis. in general, angiogenesis process is a multi-factorial and highly structu...

BACKGROUND AND OBJECTIVES A retrospective analysis was performed to assess the efficacy of various treatments of non-Hodgkin's primary bone lymphomas (PBL). DESIGN AND METHODS Fifty-two consecutive, previously untreated PBL patients were seen between the years 1982 and 1998. Information was obtained regarding each patient's presentation and clinical course. Histology was reviewed in all cases...

INTRODUCTION Esophageal cancer is the seventh most frequent malignancy in Iranian men and the fourth most common cancer in Iranian women. It is also among the 10 most frequent cancers in the world. Definitive chemo-radiation using cisplatin with 5-fluorouracil (5-FU) is known as the standard of care among various chemotherapy regimens used with esophageal cancer patients who are not eligible fo...
