What is an accession number in the cancer registry?

A unique number assigned to the patient by the registrar, indicating the year in which the patient was first seen at the reporting institution and the sequential order in which the patient was identified by the registry or abstracted into the database.

Which of the following cases are required by the CoC?

Requirements of CoC / Governing Agencies

  • Nonanalytic cases.
  • Carcinoma in-situ of the cervix.
  • Benign and borderline histologies.
  • In-situ and localized basal and squamous cell carcinomas of the skin.
  • Foreign residents.
  • Patients whose age exceeds 100 years.

What is an analytic cancer case?

Cases are broadly analytic or non-analytic cases. For example: A patient might receive the diagnosis at your facility and treatment at a different facility. The cancer is reported by both facilities. This is a common occurrence and is referred to as an “analytic” case.

Which tumor suppressor genes are associated with genetic susceptibility to breast cancer Select all that apply?

Examples of tumor suppressor genes include BRCA1, BRCA2, and p53 or TP53. Germline mutations in BRCA1 or BRCA2 genes increase a woman’s risk of developing hereditary breast or ovarian cancers and a man’s risk of developing hereditary prostate or breast cancers.

What is a population based registry?

A population-based registry contains records for people diagnosed with a specific type of disease who reside within a defined geographic region. For example, a hospital can have a breast cancer registry with records for all the women in their breast cancer treatment program.

What is the primary goal of a hospital based cancer registry?

The primary goal of the single hospital (institution) registry is to improve patient care by medical audit-type evaluation of outcomes.

How often are COC fully accredited programs surveyed?

A certificate of accreditation is issued, and these programs are surveyed at three-year intervals.

What is a case finding?

Casefinding is a system for locating every patient-inpatient or outpatient- who is diagnosed and/or treated with a reportable diagnosis. Casefinding is like casting a net far and wide to “capture” all of the reportable cancer cases.

What is a non-analytic cancer case?

Non-analytic cases are classified, in the “new” system, according to the reason a patient is non- analytic (to the reporting institution), or the reason a patient who never received care at this institution has had his/her case abstracted. Non-analytic cases are coded with two-digit numbers ranging from 30-49.

What is a non-analytic case?

Non-analytic case: All cases for which the registry does not have information on the original. diagnosis and/or first course of treatment.

What cancers are associated with BRCA1?

The BRCA1 and BRCA2 genes are two of the most common genes known to be associated with an increased risk of cancer, most notably breast cancer and ovarian cancer. When working properly, BRCA1 and BRCA2 are tumor-suppressor genes that protect the body from developing certain cancers.

How much does BRCA increase risk of breast cancer?

How much do BRCA mutations increase the risk of breast cancer? The risk of breast cancer for the average American woman is about 12% in her lifetime. Having a BRCA mutation greatly increases the risk. The estimated risk of breast cancer in women with a BRCA mutation is 45–85% by age 70 years.

What is the difference between primary and secondary accession?

The first accession number is referred to as the ‘Primary (citable) accession number’, while the others are referred to as ‘Secondary accession numbers’. These are listed in alphanumerical order.

What are the accession numbers in the entry information section?

This subsection of the ‘Entry information’ section provides one or more accession number (s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called ‘Primary (citable) accession number’.

How are accession numbers listed in alphanumerical order?

These are listed in alphanumerical order. b) If an existing entry is split into two or more entries (‘demerged’), new ‘primary’ accession numbers are attributed to all the split entries while all original accession numbers are retained as ‘secondary’ accession numbers. Example: P29358 which has been ‘demerged’ into P68250 and P68251.

What is an example of a demerged accession number?

Example: P29358 which has been ‘demerged’ into P68250 and P68251. An accession number is only deleted when the entry to which it was assigned has been removed from UniProtKB.
