Overview
Diagnostic Study of Choice
Study of choice
[Name of the investigation] is the gold standard test for the diagnosis of [disease name].
OR
The following result of [gold standard test] is confirmatory of [disease name]:
- [Result 1]
- [Result 2]
OR
[Name of the investigation] must be performed when:
- The patient presents with [symptom/sign 1], [symptom/sign 2], and [symptom/sign 3].
- A [name of test] is positive for [sign 1], [sign 2], and [sign 3] in the patient.
OR
[Name of the investigation] is the gold standard test for the diagnosis of [disease name].
OR
The diagnostic study of choice for [disease name] is [name of the investigation].
OR
There is no single diagnostic study of choice for the diagnosis of [disease name].
OR
There is no single diagnostic study of choice for the diagnosis of [disease name], but [disease name] can be diagnosed based on [name of the investigation 1] and [name of the investigation 2].
OR
[Disease name] is primarily diagnosed based on the clinical presentation.
OR
Investigations:
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most specific test for the diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most sensitive test for diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most efficient test for diagnosis.
The comparison of various diagnostic studies for [disease name]
Test | Sensitivity | Specificity |
---|---|---|
Test 1 | ...% | ...% |
Test 2 | ...% | ...% |
[Name of test with higher sensitivity and specificity] is the preferred investigation based on the sensitivity and specificity
Diagnostic results
The following finding(s) on performing [investigation name] is(are) confirmatory for [disease name]:
- [Finding 1]
- [Finding 2]
Sequence of Diagnostic Studies
The [name of investigation] must be performed when:
- The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
- A positive [test] is detected in the patient, to confirm the diagnosis.
OR
The various investigations must be performed in the following order:
- [Initial investigation]
- [2nd investigation]
Name of Diagnostic Criteria
The American Joint Committee on Cancer (AJCC) has designated staging by TNM classification to define small intestine cancer[1]:
Primary Tumor (T):
- TX-Primary tumor cannot be assessed
- T0-No evidence of primary tumor
- Tis-Carcinoma in situ
- T1a-Tumor invades lamina propria
- T1b-Tumor invades submucosa
- T2-Tumor invades muscularis propria
- T3-Tumor invades through the muscularis propria into the subserosa or into the nonperitonealized perimuscular tissue (mesentery or retroperitoneum) with extension ≤2 cm
- T4-Tumor perforates the visceral peritoneum or directly invades other organs or structures (includes other loops of small intestine, mesentery, or retroperitoneum >2 cm, and abdominal wall by way of serosa; for duodenum only, invasion of pancreas or bile duct)
Regional Lymph Nodes (N)
- NX- Regional lymph nodes cannot be assessed
- N0- No regional lymph node metastasis
- N1- Metastasis in 1–3 regional lymph nodes
- N2- Metastases in ≥4 regional lymph nodes
Distant Metastasis (M)
- M0- No distant metastasis
- M1- Distant metastasis
