Anemia treatment and the radiation oncologist: optimizing patient outcomes.
نویسندگان
چکیده
Anemia is a frequent complication of cancer and its associated treatment. Although its occurrence is well documented in the chemotherapy setting, the prevalence and nature of anemia in the radiation oncology setting have been inadequately characterized. Preliminary findings from an ongoing retrospective study at Beth Israel Medical Center in New York indicate that mild-to-moderate anemia (ie, hemoglobin levels of 10 to 12 g/dL) is common at presentation for radiation therapy and increases in prevalence and severity during the course of radiation treatment. The symptoms of mild-to-moderate anemia, particularly fatigue, can substantially impair the quality of life of cancer patients. Furthermore, an extensive body of literature has documented an association between low hemoglobin levels and poor locoregional tumor control and survival following curative-intent radiation therapy. Greater efforts by radiation oncologists to document and treat anemia in patients undergoing radiation therapy may provide an opportunity to improve postradiation outcomes and well-being.

Hypoxia and anemia: factors in decreased sensitivity to radiation therapy and chemotherapy?
Hypoxia is a common feature of solid tumors that occurs across a wide variety of malignancies. Hypoxia and anemia (which contributes to tumor hypoxia) can lead to ionizing radiation and chemotherapy resistance by depriving tumor cells of the oxygen essential for the cytotoxic activities of these agents. Hypoxia may also reduce tumor sensitivity to radiation therapy and chemotherapy through one ...
متن کاملrHuEPO and treatment outcomes: the preclinical experience.
The presence of hypoxic areas is a common feature of solid tumors and has been associated with decreased sensitivity of the tumors to radiation therapy and oxygen-dependent chemotherapeutic agents, as well as worsened outcomes, including survival. Anemia is also common in cancer patients and is believed to contribute to tumor hypoxia. Thus, the rationale exists for administering recombinant hum...

The management of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) is highly complex. Data from recent clinical trials have altered the treatment landscape by refining the use of existing therapies, such as radiation therapy and chemotherapy, and providing new treatment options, such as cetuximab. Selecting the most appropriate treatment for an individual patient require...
متن کاملRadiotherapy-associated anemia: the scope of the problem.
The impact of anemia on cancer patients undergoing chemotherapy is well established, but only recently has the prevalence of anemia in patients receiving radiotherapy received much attention. Many cancer patients present with anemia prior to radiotherapy, and even more experience anemia or a worsening of anemia at some point during treatment. However, the problem of anemia is often ignored beca...
متن کاملThe diagnosis and treatment of metastatic spinal tumor.
Metastases to the spine represent a challenging problem in an oncology practice. Treatment decisions require multidisciplinary review. Radiation therapy remains the primary treatment for metastatic spinal tumor, but advances in radiation therapy, chemotherapy, and surgery have changed the roles of each and lead to improved patient outcomes. Regardless of the treatment, diagnosis and treatment b...
