Question

A physician is performing a study of patients recently treated in your department. The purpose of the study is to compare local control and toxicity of early-stage prostate cancer patients treated with high dose per fraction radiation therapy versus those treated with conventional dose per fraction radiation therapy. A total of 437 patients will be included in the study (both groups).   The patient population being studied is:

	A.	All men
	B.	The 437 patients included in the study.
	C.	All early-stage prostate cancer patients
	D.	All prostate cancer patients

Answer 1

Answer-

According to the given question-

• Here we have a information regarding the study about the early-stage prostate cancer in which a physician is doing study on patients those recently treated in their department.
• The main purpose was to compare between the local control and to check the effect of toxicity of early-stage prostate cancer patients when they were treated with two types of doses , one group was treated with high dose per fraction radiation therapy and other group was treated with conventional dose per fraction radiation therapy.
• This study included 437 patients in which toxicity of both doses was checked.
• We know that prostate gland is belongs to  male reproductive organ and it is responsible for  secretion of  prostate fluid, which is also components of semen.
• Here we have more than 437  patients included in this study because there is also local control and the  437 are involved for study are to study the effect of toxicity of two types of doses such as high dose per fraction radiation therapy versus conventional dose per fraction radiation therapy.
• In this group all are not early-stage prostate cancer patients because there is also local control group.
• here the study is based on detection of early stage cancer not all prostate cancer patients

​​​​​​​So most correct answer will be (A) All men
