Update of treatment of abdominal tumor using radiotherapy

Atualização em tratamento de tumores abdominais com radioterapia

• 1. Is the irradiation of the abdominal area using conformal radiotherapy superior compared to conventional radiotherapy in pancreatic tumors?

  • a. Radiation entry in different angles can increase damage to the pancreas.

  • b. Radiation entry into different angles shows better results.

  • c. They have similar results in the planning of radiation therapy.

  • d. Conformal radiotherapy can produce higher irradiation of adjacent organs.

• 2. Is the irradiation of the abdominal area using conformal radiotherapy superior compared to conventional radiotherapy in sarcomas?

  • a. There is better dose distribution only in adults.

  • b. There is better dose distribution only in children.

  • c. There is better dose distribution in both children and adults.

  • d. There is no difference in the results, despite the target volume recognition feature.

• 3. Is there less toxicity in the use of conformal radiotherapy compared to conventional radiotherapy for abdominal tumors in pancreatic cancer?

  • a. There is less toxicity with conformal radiotherapy.

  • b. There is no difference in toxicity rates.

  • c. There is less toxicity with conventional radiotherapy.

  • d. The decline in renal function is similar between the two techniques.

• 4. Is there less toxicity in the use of conformal radiotherapy compared to conventional radiotherapy for abdominal tumors in sarcomas?

  • a. Bleeding rates are higher in the conformal technique.

  • b. The intestinal obstruction rates are similar.

  • c. Nephropathy rates are high in the conformal technique.

  • d. Toxicity in the conventional technique can lead to the need for hospital interventions.

• 5. Is there a difference in the effectiveness of conformal and conventional radiotherapy?

  • a. In stomach tumors relapse-free survival is higher in the conformal technique.

  • b. In sarcomas relapse-free survival is higher in the conformal technique.

  • c. In pancreatic tumors relapse-free survival is lower in the conformal technique.

  • d. In abdominal tumors overall survival is higher with conformal technique.

Answers to clinical scenario: femoral neck fracture in children: treatment and complications [published in RAMB 2015; 61(1)]

• 1. Most relevant risk factors for the development of avascular necrosis after femoral neck fractures do NOT include:

  • Gender and race (Alternative C).

• 2. Surgical or conservative treatment?

  • Fracture surgical fixation is recommended (Alternative B).

• 3. What kind of reduction (open or closed) is most appropriate in this type of fracture?

  • Anatomical reduction (closed or open) (Alternative D).

• 4. Does early hip decompression reduce the risk of avascular necrosis (AVN)?

  • Decompression of the early hematoma reduces the risk of AVN (Alternative A).

• 5. What is the maximum time between the accident and early therapeutic approach to minimize the most common complications?

  • The first 24 hours (Alternative B).
