Detection of occult lymph node metastases in esophageal cancer by minimally invasive staging combined with molecular diagnostic techniques. (1/3372)
BACKGROUND AND OBJECTIVES: Lymph node metastases are the most important prognostic factor in patients with esophageal cancer. Histologic examination misses micrometastases in up to 20% of lymph nodes evaluated. In addition, non-invasive imaging modalities are not sensitive enough to detect small lymph nodes metastases. The objective of this study was to investigate the use of reverse transcriptase-polymerase chain reaction (RT-PCR) of messenger RNA (mRNA) for carcinoembryonic antigen (CEA) to increase the detection of micrometastases in lymph nodes from patients with esophageal cancer. METHODS: RT-PCR of CEA mRNA was performed in lymph nodes from patients with malignant and benign esophageal disease. Each specimen was examined histopathologically and by RT-PCR and the results were compared. RESULTS: Metastases were present in 29 of 60 (48%) lymph nodes sample by minimally invasive staging from 13 patients with esophageal cancer when examined histopathologically. RT-PCR identified nodal metastases in 46 of these 60 (77%) samples. RT-PCR detected CEA mRNA in all 29 histologically positive samples and in 17 histologically negative lymph nodes. All lymph nodes from patients with benign disease (n = 15) were negative both histopathologically and by RT-PCR. The stage of two patients was reclassified based on the RT-PCR results, which identified lymph node spread undetected histopathologically. Both of these patients developed recurrent disease after resection of the primary tumor. CONCLUSIONS: RT-PCR is more sensitive than histologic examination in the detection of lymph node metastases in esophageal cancer and can lead to diagnosis of a more advanced stage in some patients. The combination of minimally invasive surgical techniques in combination with new molecular diagnostic techniques may improve our ability to stage cancer patients. (+info)Medullary thyroid carcinoma with multiple hepatic metastases: treatment with transcatheter arterial embolization and percutaneous ethanol injection. (2/3372)
A 54-year-old man with medullary thyroid carcinoma in the thyroid gland was unable to undergo total thyroidectomy because the tumor had invaded the mediastinum. Radiation therapy and chemotherapy were given. Seven years later, intractable diarrhea and abdominal pain appeared, and computed tomography demonstrated hypervascular tumors in the thyroid gland and in the liver. The tumors were successfully treated with percutaneous ethanol injection to a lesion in the thyroid gland and transcatheter arterial embolization followed by percutaneous ethanol injection to tumors in the liver. Transcatheter arterial embolization and percutaneous ethanol injection may be valuable in treating medullary thyroid carcinoma. (+info)The intrarenal vascular lesions associated with primary antiphospholipid syndrome. (3/3372)
Even 10 yr after the identification of the antiphospholipid syndrome (APS), renal involvement in the course of APS is still relatively unrecognized, and is probably underestimated. The association of anticardiolipin antibodies and/or lupus anticoagulant with the development of a vaso-occlusive process involving numerous organs is now confirmed. In a multicenter study, 16 cases of "primary" APS (PAPS) were found and followed for 5 yr or more, all with renal biopsy. In all 16 cases of PAPS, there was a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries (12 patients), recanalizing thrombi in arteries and arterioles (six patients), and focal cortical atrophy (10 patients). In combination, these led to progressive destruction of the kidney, accelerated by acute glomerular and arteriolar microangiopathy in five patients. Focal cortical atrophy is a distinctive lesion, present in 10 biopsies, and likely represents the histologic and functional renal analogue to the multiple cerebral infarcts detected on imaging studies. The clinical hallmark of this vascular nephropathy in PAPS is systemic hypertension, only variably associated with renal insufficiency, proteinuria, or hematuria. The ensemble of histologic renal lesions defined in this study should aid in the separation of the lesions found in cases of secondary APS, especially systemic lupus erythematosus, into those lesions related to APS and those related to the underlying disease. (+info)Nodular glomerulosclerosis with deposition of monoclonal immunoglobulin heavy chains lacking C(H)1. (4/3372)
The objective of this study was to further characterize the clinical and immunopathologic features of heavy chain deposition disease (HCDD), a recently described entity. Four patients were diagnosed as having HCDD on a kidney biopsy. All presented with nodular glomerulosclerosis with deposition of gamma1 heavy chains lacking CH1 epitopes, but without light chains. Two different patterns were observed in the serum. First, patients 1 and 2 had a circulating monoclonal IgGlambda containing a short gamma1 heavy chain lacking CH1 epitopes, with an apparent molecular weight of 40 kD consistent with a complete CH1 deletion. Biosynthetic experiments also showed that the deleted heavy chain was produced in excess compared with light chains, and was secreted in vitro together with half Ig molecules, although these abnormal components were not detected by Western blot analysis of whole serum. Second, patients 3 and 4 had a circulating monoclonal IgG1lambda with an apparently normal, nondeleted heavy chain subunit, but serum fractionation followed by immunoblotting revealed an isolated monoclonal gamma1 chain lacking CH1 epitopes. These data strongly suggest that renal deposition of a CH1-deleted heavy chain circulating in low amounts in the serum as a free unassembled subunit is a major feature of HCDD. The CH1 deletion is most likely responsible for the premature secretion in blood of the heavy chain by a clone of plasma cells. (+info)Angiotensin II receptor type 1 gene expression in human glomerulonephritis and diabetes mellitus. (5/3372)
The renin-angiotensin system plays an important role in the progression of chronic renal disease. Although the expression of renin and angiotensin-converting enzyme in experimental and human renal disease has been well characterized, no information is available regarding human angiotensin type 1 (AT1) receptor expression. The net effect of renin depends on AT1 receptor expression, among other factors. Receptor expression was determined in renal biopsy samples (including all tissue components) and isolated glomeruli from patients with glomerulonephritis (GN) or diabetic nephropathy (non-insulin-dependent diabetes mellitus). Biopsy samples and isolated glomeruli from tumor-free tissue from tumor nephrectomies served as controls. Human AT1 receptor gene expression was determined by quantitative reverse transcription-PCR, using an AT1 receptor deletion mutant as the internal standard. In whole biopsy samples from 37 patients with various types of GN, AT1 receptor mRNA levels were lower, compared with nine control biopsy samples (P < 0.001). AT1 receptor mRNA levels were also significantly lower (P < 0.001) in eight samples from patients with diabetic nephropathy. In microdissected glomeruli, AT1 receptor gene expression was significantly lower in samples from patients (n = 22) with various types of GN, compared with 12 microdissected tumor nephrectomy control samples (P < 0.0023). It is concluded that AT1 receptor mRNA expression is low in glomeruli of patients with chronic renal disease. This may reflect a regulatory response to (inappropriately) high intrarenal angiotensin II concentrations. (+info)Bone marrow scintigraphy using technetium-99m antigranulocyte antibody in malignant lymphomas. (6/3372)
BACKGROUND: The purpose of this study was to elucidate the clinical reliability of immunoscintigraphy (IS) to detect infiltration of the bone marrow in patients with malignant lymphoma. PATIENTS AND METHODS: Whole body IS was performed in 103 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) using Tc-99m labelled anti-NCA-95 which allows visualization of the granulopoietic bone marrow. Of these, 52% were studied prior to any therapy. Findings were compared to posterior iliac crest biopsy as well as MRI and/or follow-up examination. Criteria of marrow infiltration were a positive biopsy, positive follow-up, or positive results of MRI. RESULTS: Comparison of IS and biospy revealed concordant findings in 69 and discordant findings in 34 of 103 patients. Of the 34 patients with discordant results, IS showed lesions suspicious of bone marrow infiltration in 29 patients despite normal biopsy findings. When follow-up and additional examinations were taken into consideration, 10 patients remained with probably false positive and five with false negative IS findings. IS proved to be highly sensitive and specific in patients with HD (100% and 84%, respectively) and high-grade NHL (93% and 84%, respectively). Moderate sensitivity (60%) was found in low-grade NHL. This was possibly due to false negative IS in three to five patients with chemotherapy in contrast to one of five false negative results in patients without chemotherapy. CONCLUSION: Bone marrow scintigraphy using antigranulocyte antibodies is highly sensitive in HD and high-grade NHL. Positive findings in IS subsequent to a negative biopsy should be followed by guided re-biopsy or MRI. (+info)Benzodiazepine premedication: can it improve outcome in patients undergoing breast biopsy procedures? (7/3372)
BACKGROUND: Women awaiting needle-guided breast biopsy procedures may experience high anxiety levels. A randomized, double-blind, placebo-controlled study was designed to evaluate the ability of midazolam and diazepam (in a lipid emulsion [Dizac]) to improve patient comfort during needle localization and breast biopsy procedures. METHODS: Ninety women received two consecutive doses of a study medication, one before the mammographic needle localization and a second before entering the operating room. Patients were assigned randomly to receive saline, 2.0 ml intravenously, at the two time points; midazolam, 1.0 mg intravenously and 2.0 mg intravenously; or diazepam emulsion, 2.0 mg intravenously and 5.0 mg intravenously, respectively. Patients assessed their anxiety levels before the needle localization, before entering the operating room, and on arrival in the operating room. Patients completed a questionnaire evaluating their perioperative experience at the time of discharge. RESULTS: Patient satisfaction during needle localization was significantly improved in both benzodiazepine treatment groups (vs. saline). The incidence of moderate-to-severe discomfort during needle localization was lower in the midazolam (20%) and diazepam emulsion (6%) groups compared with the saline group (70%) (P<0.05). The preoperative visual analogue scale anxiety scores were similar in all three groups. In the operating room, however, anxiety scores were 55% and 68% lower after midazolam (21+/-19) and diazepam emulsion (15+/-14) compared with saline (46+/-28). Finally, there was no difference in the time to achieve home-readiness or actual discharge time among the three groups. CONCLUSIONS: Premedication with midazolam or diazepam emulsion improved patients' comfort during needle localization procedures and significantly reduced intraoperative anxiety levels before breast biopsy procedures without prolonging discharge times. Use of diazepam emulsion may be an effective alternative to midazolam in this population. (+info)Evaluation of "solitary" thyroid nodules in a community practice: a managed care approach. (8/3372)
Evaluation of thyroid nodules remains a challenge for primary care physicians. To include or exclude the presence of malignancy in a thyroid nodule, radioisotope scan, ultrasound, and fine-needle aspiration biopsy of the thyroid generally are used. The objectives of this study were to determine the utility and cost effectiveness of fine-needle aspiration biopsy of solitary thyroid nodules in a community setting; to compare the cost of fine-needle aspiration biopsy with that of radioisotope scan and ultrasound; and to determine whether the practice of obtaining radioisotope scans and ultrasound has changed in the 1990s compared with the 1980s. Patients were referred by community physicians to university-based endocrinologists for evaluation of thyroid nodules. Many of the patients had previously undergone radioisotope scans and ultrasound scans at the discretion of their primary care physicians. All patients underwent fine-needle aspiration biopsy. The biopsy results were evaluated prospectively, and the practice of community physicians' obtaining radioisotope scans and ultrasound scans was compared for the 1980s and 1990s. Eighty-three patients underwent 104 biopsies. In 20 biopsies the specimens were inadequate; the others showed 70 benign, 9 suspicious, and 4 malignant lesions. All four patients with biopsy findings read as malignant were found to have malignant growth at surgical procedures. Two benign biopsy findings were false-negative results. Malignant growth was correctly diagnosed later for one patient at a second biopsy and for the other because of growth of the nodule. The cost of 104 biopsies was $20,800. The cost of radioisotope scans was $22,400, and the cost of ultrasound scans was $10,640. The frequency of obtaining radioisotope scans (84.5% vs 77%) and ultrasound scans (65% vs 45%) was slightly higher in the 1990s compared with the 1980s. Fine-needle aspiration biopsy is a safe and cost effective initial evaluation modality for smaller community-based centers, as it is at large tertiary centers. The cost incurred ($33,040) in obtaining the radioisotope scans and ultrasound scans could have been saved if fine-needle aspiration biopsy had been used as the initial diagnostic procedure for evaluation of these nodules. Although radioisotope scan and ultrasound scan are of little diagnostic help in the evaluation of thyroid nodules, they continued to be obtained at a high frequency during the last decade. (+info)In the context of medicine, "needles" are thin, sharp, and typically hollow instruments used in various medical procedures to introduce or remove fluids from the body, administer medications, or perform diagnostic tests. They consist of a small-gauge metal tube with a sharp point on one end and a hub on the other, where a syringe is attached.
There are different types of needles, including:
1. Hypodermic needles: These are used for injections, such as intramuscular (IM), subcutaneous (SC), or intravenous (IV) injections, to deliver medications directly into the body. They come in various sizes and lengths depending on the type of injection and the patient's age and weight.
2. Blood collection needles: These are used for drawing blood samples for diagnostic tests. They have a special vacuum-assisted design that allows them to easily penetrate veins and collect the required amount of blood.
3. Surgical needles: These are used in surgeries for suturing (stitching) wounds or tissues together. They are typically curved and made from stainless steel, with a triangular or reverse cutting point to facilitate easy penetration through tissues.
4. Acupuncture needles: These are thin, solid needles used in traditional Chinese medicine for acupuncture therapy. They are inserted into specific points on the body to stimulate energy flow and promote healing.
It is essential to follow proper infection control procedures when handling and disposing of needles to prevent the spread of bloodborne pathogens and infectious diseases.
A needle biopsy is a medical procedure in which a thin, hollow needle is used to remove a small sample of tissue from a suspicious or abnormal area of the body. The tissue sample is then examined under a microscope to check for cancer cells or other abnormalities. Needle biopsies are often used to diagnose lumps or masses that can be felt through the skin, but they can also be guided by imaging techniques such as ultrasound, CT scan, or MRI to reach areas that cannot be felt. There are several types of needle biopsy procedures, including fine-needle aspiration (FNA) and core needle biopsy. FNA uses a thin needle and gentle suction to remove fluid and cells from the area, while core needle biopsy uses a larger needle to remove a small piece of tissue. The type of needle biopsy used depends on the location and size of the abnormal area, as well as the reason for the procedure.
A biopsy is a medical procedure in which a small sample of tissue is taken from the body to be examined under a microscope for the presence of disease. This can help doctors diagnose and monitor various medical conditions, such as cancer, infections, or autoimmune disorders. The type of biopsy performed will depend on the location and nature of the suspected condition. Some common types of biopsies include:
1. Incisional biopsy: In this procedure, a surgeon removes a piece of tissue from an abnormal area using a scalpel or other surgical instrument. This type of biopsy is often used when the lesion is too large to be removed entirely during the initial biopsy.
2. Excisional biopsy: An excisional biopsy involves removing the entire abnormal area, along with a margin of healthy tissue surrounding it. This technique is typically employed for smaller lesions or when cancer is suspected.
3. Needle biopsy: A needle biopsy uses a thin, hollow needle to extract cells or fluid from the body. There are two main types of needle biopsies: fine-needle aspiration (FNA) and core needle biopsy. FNA extracts loose cells, while a core needle biopsy removes a small piece of tissue.
4. Punch biopsy: In a punch biopsy, a round, sharp tool is used to remove a small cylindrical sample of skin tissue. This type of biopsy is often used for evaluating rashes or other skin abnormalities.
5. Shave biopsy: During a shave biopsy, a thin slice of tissue is removed from the surface of the skin using a sharp razor-like instrument. This technique is typically used for superficial lesions or growths on the skin.
After the biopsy sample has been collected, it is sent to a laboratory where a pathologist will examine the tissue under a microscope and provide a diagnosis based on their findings. The results of the biopsy can help guide further treatment decisions and determine the best course of action for managing the patient's condition.
Interventional radiography is a subspecialty of radiology that uses imaging guidance (such as X-ray fluoroscopy, ultrasound, CT, or MRI) to perform minimally invasive diagnostic and therapeutic procedures. These procedures typically involve the insertion of needles, catheters, or other small instruments through the skin or a natural body opening, allowing for targeted treatment with reduced risk, trauma, and recovery time compared to traditional open surgeries.
Examples of interventional radiography procedures include:
1. Angiography: Imaging of blood vessels to diagnose and treat conditions like blockages, narrowing, or aneurysms.
2. Biopsy: The removal of tissue samples for diagnostic purposes.
3. Drainage: The removal of fluid accumulations (e.g., abscesses, cysts) or the placement of catheters to drain fluids continuously.
4. Embolization: The blocking of blood vessels to control bleeding, tumor growth, or reduce the size of an aneurysm.
5. Stenting and angioplasty: The widening of narrowed or blocked vessels using stents (small mesh tubes) or balloon catheters.
6. Radiofrequency ablation: The use of heat to destroy tumors or abnormal tissues.
7. Cryoablation: The use of extreme cold to destroy tumors or abnormal tissues.
Interventional radiologists are medical doctors who have completed specialized training in both diagnostic imaging and interventional procedures, allowing them to provide comprehensive care for patients requiring image-guided treatments.
The jugular veins are a pair of large, superficial veins that carry blood from the head and neck to the heart. They are located in the neck and are easily visible when looking at the side of a person's neck. The external jugular vein runs along the surface of the muscles in the neck, while the internal jugular vein runs within the carotid sheath along with the carotid artery and the vagus nerve.
The jugular veins are important in clinical examinations because they can provide information about a person's cardiovascular function and intracranial pressure. For example, distention of the jugular veins may indicate heart failure or increased intracranial pressure, while decreased venous pulsations may suggest a low blood pressure or shock.
It is important to note that medical conditions such as deep vein thrombosis (DVT) can also affect the jugular veins and can lead to serious complications if not treated promptly.
Interventional ultrasonography is a medical procedure that involves the use of real-time ultrasound imaging to guide minimally invasive diagnostic and therapeutic interventions. This technique combines the advantages of ultrasound, such as its non-ionizing nature (no radiation exposure), relatively low cost, and portability, with the ability to perform precise and targeted procedures.
In interventional ultrasonography, a specialized physician called an interventional radiologist or an interventional sonographer uses high-frequency sound waves to create detailed images of internal organs and tissues. These images help guide the placement of needles, catheters, or other instruments used during the procedure. Common interventions include biopsies (tissue sampling), fluid drainage, tumor ablation, and targeted drug delivery.
The real-time visualization provided by ultrasonography allows for increased accuracy and safety during these procedures, minimizing complications and reducing recovery time compared to traditional surgical approaches. Additionally, interventional ultrasonography can be performed on an outpatient basis, further contributing to its appeal as a less invasive alternative in many clinical scenarios.
A "large-core needle biopsy" is a medical procedure in which a large-bore needle is used to obtain a tissue sample from the body for diagnostic examination. This type of biopsy allows for the removal of a larger piece of tissue than what can be obtained with a fine-needle aspiration biopsy, and it is often used when a mass or abnormality can be felt during a physical exam.
During the procedure, the healthcare provider will use imaging guidance (such as ultrasound, CT scan, or MRI) to help guide the needle into the appropriate location. Once the needle is in place, it is advanced into the mass or abnormality and a core of tissue is removed for analysis. The sample is then sent to a laboratory where a pathologist will examine the tissue under a microscope to determine if there are any abnormal cells present that may indicate cancer or other diseases.
Large-core needle biopsies are generally considered safe, but like all medical procedures, they do carry some risks, such as bleeding, infection, and discomfort at the biopsy site. Patients should discuss any concerns with their healthcare provider before undergoing the procedure.
A fine-needle biopsy (FNB) is a medical procedure in which a thin, hollow needle is used to obtain a sample of cells or tissue from a suspicious or abnormal area in the body, such as a lump or mass. The needle is typically smaller than that used in a core needle biopsy, and it is guided into place using imaging techniques such as ultrasound, CT scan, or MRI.
The sample obtained during an FNB can be used to diagnose various medical conditions, including cancer, infection, or inflammation. The procedure is generally considered safe and well-tolerated, with minimal risks of complications such as bleeding, infection, or discomfort. However, the accuracy of the diagnosis depends on the skill and experience of the healthcare provider performing the biopsy, as well as the adequacy of the sample obtained.
Overall, FNB is a valuable diagnostic tool that can help healthcare providers make informed decisions about treatment options and improve patient outcomes.
An image-guided biopsy is a medical procedure in which imaging technologies, such as ultrasound, CT (computed tomography), MRI (magnetic resonance imaging), or mammography, are used to guide the removal of tissue samples from a suspicious area in the body for further examination and diagnosis. This technique allows healthcare professionals to obtain biopsy specimens precisely and accurately, even from deep-seated or hard-to-reach locations, minimizing injury to surrounding tissues and improving diagnostic confidence. The type of imaging modality used depends on the location, size, and nature of the suspected abnormality.
Needle sharing is the reuse of needles or syringes by more than one person, often in the context of injecting drugs. This behavior is considered high-risk as it can lead to the transmission of bloodborne pathogens such as HIV, Hepatitis B, and Hepatitis C. It's a significant public health concern due to its association with intravenous drug use.
Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA) is a medical procedure that combines the use of endoscopy and ultrasound to guide the fine needle aspiration biopsy of internal organs or lesions. This technique allows for the sampling of tissue from inside the gastrointestinal tract and adjacent organs such as the pancreas, lymph nodes, and liver.
During the procedure, an endoscope equipped with an ultrasound probe is inserted through the patient's mouth and advanced to the area of interest. The ultrasound probe provides real-time images of the internal organs and lesions, allowing the physician to guide the fine needle into the target tissue. Once the needle is in position, suction is applied to collect a sample of cells or fluid for further examination under a microscope.
EUS-FNA is commonly used to diagnose and stage various types of cancer, as well as to evaluate other conditions such as pancreatitis, chronic liver disease, and gastrointestinal submucosal tumors. The procedure is generally safe and well-tolerated, with minimal risks and complications. However, as with any medical procedure, there are potential risks and benefits that should be discussed with a healthcare provider before undergoing EUS-FNA.
A syringe is a medical device used to administer or withdraw fluids, typically liquids or gases. It consists of a narrow tube, usually made of plastic or glass, connected to a handle that contains a plunger. The plunger is used to draw fluid into the tube by creating a vacuum, and then to expel the fluid when pressure is applied to the plunger. Syringes come in various sizes and are used for a wide range of medical procedures, including injections, wound care, and specimen collection. They are an essential tool in the medical field and are used daily in hospitals, clinics, and other healthcare settings.
Neoplasm seeding, also known as tumor seeding or iatrogenic implantation, is a rare complication that can occur during surgical procedures. It refers to the accidental spread of cancer cells from the primary tumor site to other locations in the body, usually along the path of a surgical incision or via bodily fluids. This can result in new tumor growths (metastases) at these sites, which may complicate treatment and worsen the patient's prognosis.
Neoplasm seeding is more commonly associated with certain types of surgeries, such as those involving the liver, pancreas, or other organs with highly vascular tumors. It can also occur during biopsy procedures, where a needle is used to remove tissue samples for diagnostic purposes. While neoplasm seeding is a known risk of these procedures, it is relatively uncommon and often outweighed by the benefits of timely and effective treatment.
Needlestick injuries are sharp object injuries typically involving hollow-bore needles, which can result in exposure to bloodborne pathogens. They often occur during the use or disposal of contaminated needles in healthcare settings. These injuries pose a significant risk for transmission of infectious diseases such as HIV, Hepatitis B, and Hepatitis C. It is essential to follow strict protocols for handling and disposing of needles and other sharp objects to minimize the risk of needlestick injuries.
A sentinel lymph node biopsy is a surgical procedure used in cancer staging to determine if the cancer has spread beyond the primary tumor to the lymphatic system. This procedure involves identifying and removing the sentinel lymph node(s), which are the first few lymph nodes to which cancer cells are most likely to spread from the primary tumor site.
The sentinel lymph node(s) are identified by injecting a tracer substance (usually a radioactive material and/or a blue dye) near the tumor site. The tracer substance is taken up by the lymphatic vessels and transported to the sentinel lymph node(s), allowing the surgeon to locate and remove them.
The removed sentinel lymph node(s) are then examined under a microscope for the presence of cancer cells. If no cancer cells are found, it is unlikely that the cancer has spread to other lymph nodes or distant sites in the body. However, if cancer cells are present, further lymph node dissection and/or additional treatment may be necessary.
Sentinel lymph node biopsy is commonly used in the staging of melanoma, breast cancer, and some types of head and neck cancer.
Sensitivity and specificity are statistical measures used to describe the performance of a diagnostic test or screening tool in identifying true positive and true negative results.
* Sensitivity refers to the proportion of people who have a particular condition (true positives) who are correctly identified by the test. It is also known as the "true positive rate" or "recall." A highly sensitive test will identify most or all of the people with the condition, but may also produce more false positives.
* Specificity refers to the proportion of people who do not have a particular condition (true negatives) who are correctly identified by the test. It is also known as the "true negative rate." A highly specific test will identify most or all of the people without the condition, but may also produce more false negatives.
In medical testing, both sensitivity and specificity are important considerations when evaluating a diagnostic test. High sensitivity is desirable for screening tests that aim to identify as many cases of a condition as possible, while high specificity is desirable for confirmatory tests that aim to rule out the condition in people who do not have it.
It's worth noting that sensitivity and specificity are often influenced by factors such as the prevalence of the condition in the population being tested, the threshold used to define a positive result, and the reliability and validity of the test itself. Therefore, it's important to consider these factors when interpreting the results of a diagnostic test.
