Skin biopsy and skin cancer treatment use in the Medicare population, 1993 to 2016.

BACKGROUND: Skin biopsies are increasing at a rapid rate, and some may be unnecessary. Although skin cancer incidence is rising, there is varied biopsy accuracy between dermatologists and advanced practice professionals (APPs). A comparison of Current Procedural Terminology code (American Medical Association, Chicago, IL) use for skin biopsy and skin cancer treatment over 18 years and a comparison of provider types is needed. Excess skin biopsies increase health care costs and patient morbidity. OBJECTIVE: To examine changes in skin biopsy and skin cancer treatment utilization rates per year in the Medicare fee-for-service (FFS) population and to compare skin biopsy utilization rates between dermatologists and APPs. METHODS: Retrospective cross-sectional study of Medicare FFS paid claims using the Centers for Medicare and Medicaid Services Physician Claims databases. We calculated the number of skin biopsies and skin cancer treatments in the Medicare FFS population from 1993 to 2016, and percentage use by provider type from 2001 to 2016. Our primary outcome measurements were the number of skin biopsies and skin cancer treatments per 1000 Medicare FFS beneficiaries per year and the number of additional skin biopsies per 1000 Medicare FFS beneficiaries per year, or the difference in the number of skin biopsies and number of skin cancer treatments per 1000 Medicare FFS beneficiaries. Our secondary outcome measurements were the skin biopsy-to-skin cancer treatment ratio and the number of procedures per 1000 Medicare FFS beneficiaries per year by provider type. RESULTS: After adjusting for the number of enrollees in the Medicare FFS population from 1993 to 2016, skin biopsies per 1000 Medicare FFS beneficiaries increased 153% (from 39.31 to 99.33), and skin cancer treatments per 1000 Medicare FFS beneficiaries increased 39% (from 34.67 to 48.26). Between 1993 and 2016, the skin biopsy-to-skin cancer treatment ratio increased 81% (from 1.134 to 2.058), and the number of additional biopsies per 1000 Medicare FFS beneficiaries increased 1001% (from 4.638 to 51.072) between 1993 and 2016. Utilization data by provider type is available from 2001 to 2016. The number of skin biopsies per 1000 Medicare beneficiaries performed by APPs increased from 0.82 to 17.19 or 1996% (nurse practitioners, 2211%; physician assistants, 1916%) and the number of biopsies by dermatologists increased by 41% from 53.98 to 76.17. LIMITATIONS: Medicare claims data do not provide specific information regarding skin biopsy or skin cancer treatment use. CONCLUSION: The number of skin biopsies has risen 153% since 1993, while the number of skin cancer treatments has only increased 39%. Our data highlight the rise of biopsy use and the increase in biopsies that do not result in skin cancer diagnosis or treatment. This suggests APPs may be responsible for increasing the cost of skin cancer management by biopsying significantly more benign lesions than dermatologists.

Recent Advances and Current Role of Transperineal Prostate Biopsy.

"Approximately 1 million prostate biopsies are performed each year in the United States. This procedure has traditionally been performed using a transrectal approach, which is associated with a significant risk of infectious complications including sepsis. In recent years, transperineal prostate biopsy has been increasingly adopted due to its lower associated infectious risk. In this review, we explore the benefits of the transperineal approach for performing prostate biopsy and detail technical advancements that have allowed for this procedure to now be routinely performed in the outpatient settings under local anesthesia."

Metastatic pulmonary calcification diagnosed by transbronchial cryobiopsy.

Metastatic pulmonary calcification is a rare disease characterized by calcium deposits in the lung. We describe a case where this pathology is observed associated with bone lithic lesions and kidney failure and it was diagnosed with transbronchial cryobiopsy.

Trophectoderm biopsy reduces the level of serum ß-human chorionic gonadotropin in early pregnancy.

OBJECTIVE: To assess whether trophectoderm biopsy has any impact on the level of serum ß-human chorionic gonadotropin (ß-hCG) in early pregnancies. DESIGN: Retrospective cohort study. SETTING: University-affiliated reproductive medical center. PATIENT(S): Three hundred and eighty-three women undergoing 396 frozen embryo transfer (FET) cycles with preimplantation genetic testing (PGT), and 353 women undergoing 465 FET cycles with in vitro fertilization or intracytoplasmic sperm injection, all women having positive serum ß-hCG results on the 12th day after blastocysts transfers. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Serum ß-hCG levels on the 12th day after warmed blastocyst transfer and perinatal outcomes of clinical pregnancy. RESULTS: The diagnostic threshold of serum ß-hCG levels on the 12th day after FET for prediction of a live birth was 368.55 mIU/mL with an area under the curve of 0.791 (0.729∼0.853) in the biopsy group, which was lower than the 411.45 mIU/mL in the control group. The average level of serum ß-hCG in the biopsy group with clinical pregnancies was statistically significantly lower than that of the control group: 703.10 (569.63) versus 809.20 (582.00), respectively. No statistically significant differences in perinatal outcomes, including gestational age, hypertensive disorder in pregnancy, and neonatal malformation, were found between the two groups. CONCLUSION(S): Trophectoderm biopsy may reduce the level of serum ß-hCG in early pregnancies (the 12th day after embryo transfer), but no increased risk was found of adverse perinatal outcomes after trophectoderm biopsy.

Changing trends in dermatology practice during COVID-19 pandemic: A single tertiary center experience.

The aim of this study was to evaluate the changing trends in dermatology clinical practice at a tertiary center during the coronavirus disease 2019 (COVID-19) pandemic. This retrospective cohort study was conducted on patients who were admitted to Ufuk University Hospital with dermatologic complaints/diseases before and during the pandemic. The patients were divided into two groups: (a) the pre-pandemic period (March-May 2019) and (b) the Pandemic period (March-May 2020). Demographic features, clinical characteristics, dermatologic diseases/complaints, dermatologic procedures/interventions, hospitalization rate, and use of biologic agents were compared between the two groups. Total number of hospital admissions have decreased from 1165 to 717. Admission rates for acne, dermatophytosis, and benign neoplasm of the skin significantly lower during the pandemic period (P values were .02, .04, and .006, respectively). Contact dermatitis, acne accompanying dermatitis, cicatricial hair loss, lichen planus, and zona zoster infection rates were significantly higher (P values were .007, <.001, .009, .04, and .03, respectively). Rates of biopsy and electrocautery procedures were decreased significantly (P values were <.001 and .002, respectively). The hospitalization rate was similar between the groups (P = .51). However, the use of biologic agents significantly decreased during the pandemic period (P = .01). Updated clinical protocols should be established for the new normal period in accordance with these findings.

The significance of multidisciplinary classifications based on transbronchial pathology in possible idiopathic interstitial pneumonias.

Surgical lung biopsy is regarded as the golden standard for the diagnosis of idiopathic interstitial pneumonias (IIPs). Here, we attempted to show the diagnostic accuracy of multidisciplinary classifications based on transbronchial pathology including transbronchial lung cryobiopsy (TBLC) , bronchoalveolar lavage fluid (BALF) and endobronchial ultrasound-guided transbronchial needle aspiration biopsy (EBUS-TBNA).Patients with suspected interstitial lung diseases admitted from June 1, 2016 to December 31, 2018 were involved. Patients with known causes of interstitial lung diseases and typical idiopathic pulmonary fibrosis diagnosed through clinical, radiological information were excluded. Patients with atypical idiopathic pulmonary fibrosis and possible IIPs accepted transbronchial pathological evaluation. Initial multidisciplinary diagnosis (MDD) classifications were made depending on clinical, radiological and transbronchial pathological information by a multidisciplinary team (MDT). The final MDD classifications were confirmed by subsequent therapeutic effects. All patients were followed up for at least 6 months.A total of 70 patients were finally involved. The samples of lung parenchyma extracted through TBLC were enough for confirmation of pathological diagnoses in 68.6% (48/70) cases. Samples of 6 cases were extracted by EBUS-TBNA. Bacteriological diagnoses were positive in 1 case by BALF. Pathological diagnoses of 77.1% (54/70) cases were achieved through TBLC, EBUS-TBNA and BALF. During the follow up study, the pulmonary lesions of 60% patients were improved, 11.43% were relapsed when glucocorticoid was reduced to small dose or withdrawal, 14.29% were leveled off and 8.57% were progressed. The diagnoses of 4 patients with progressed clinical feature were revised. As a result, 94.3% initial MDD classifications based on transbronchial pathology were consistent with the final MDD, and the difference of diagnostic yield wasn't significant between initial and final MDD (Z = -1.414, P = .157).Classifications of IIPs based on transbronchial pathology were useful and quite agreed with final MDD.

The dawn of the future: 30 years from the first biopsy of a human embryo. The detailed history of an ongoing revolution.

Following early studies showing no adverse effects, cleavage stage biopsy by zona drilling using acid Tyrode's solution, and removal of single blastomeres for preimplantation genetic testing (PGT) and identification of sex in couples at risk of X-linked disease, was performed by Handyside and colleagues in late 1989, and pregnancies reported in 1990. This method was later used for specific diagnosis of monogenic conditions, and a few years later also for chromosomal structural and/or numerical impairments, thereby establishing a valuable alternative option to prenatal diagnosis. This revolutionary approach in clinical embryology spread worldwide, and several other embryo biopsy strategies developed over three decades in a process that is still ongoing. The rationale of this narrative review is to outline the different biopsy approaches implemented across the years in the workflow of the IVF clinics that provided PGT: their establishment, the first clinical experiences, their downsides, evolution, improvement and standardization. The history ends with a glimpse of the future: minimally/non-invasive PGT and experimental embryo micromanipulation protocols. This grand theme review outlines a timeline of the evolution of embryo biopsy protocols, whose implementation is increasing worldwide together with the increasing application of PGT techniques in IVF. It represents a vade mecum especially for the past, present and upcoming operators and experts in this field to (re)live this history from its dawn to its most likely future.

Feasibility study of ultrasound video bronchoscopy for sampling endobronchial lesions.

INTRODUCTION: Endobronchial biopsy using forceps is generally performed with a standard bronchoscope, while a needle is used with an endobronchial ultrasound (EBUS) bronchoscope. An EBUS video bronchoscope, such as the EB-530US instrument (Fujifilm, Tokyo, Japan), provides good visibility and may, therefore, enable both forceps biopsies and needle aspirations to be performed. OBJECTIVES: The aim of this study was to investigate the feasibility of performing forceps biopsies and needle aspirations using the EBUS video bronchoscope for diagnosing endobronchial lesions. METHODS: Seventy patients with suspected endobronchial lesions based on a computed tomography scan were recruited and underwent forceps biopsy using the EB-530US EBUS bronchoscope. If the result of a rapid on-site cytological evaluation was negative, an additional needle aspiration of the same lesion or other target lesions was performed. The primary outcome was the completion rate of bronchoscopy, using only the EBUS bronchoscope without removal. RESULTS: In the 70 patients, forceps biopsies and/or needle aspirations using the EBUS video bronchoscope were performed and completed without removing the EBUS bronchoscope in 67 patients (95.7%). The remaining three patients required the removal of the EBUS bronchoscope from the trachea (blood clot obstruction of the working channel in one patient and change to a thin bronchoscope to sample an EBUS bronchoscope-inaccessible lesion in two others). The EBUS bronchoscope provided diagnostic material in 66 patients (94.3%). One case each of bleeding and pneumonia were observed (1.4%). CONCLUSION: Both forceps biopsy and needle aspiration are feasible using a Fujifilm EB-530US EBUS video bronchoscope.

The utility of liver biopsy in 2020.

PURPOSE OF REVIEW: Over the past decade, imaging modalities and serological tests have emerged as important tools in the evaluation of liver diseases, in many cases supplanting the use of liver biopsy and histological examination. Nonetheless, the accuracy and diagnostic value of these methods may not always be conclusive and the assessment of liver histology often remains the gold standard for diagnostic evaluation. The purpose of this review is to summarize the current role of liver biopsy in contemporary hepatology practice. RECENT FINDINGS: Technical factors were found to influence the diagnostic value of liver biopsy and histological examination of the liver, including specimen number and size (preferably ≥3 nonfragmented specimens of >20 mm in length), needle diameter (1.6 mm Menghini), number of passes (mean 2.5), imaging-guidance, and operator experience. Liver biopsy was demonstrated to be diagnostically valuable in the evaluation of persistently abnormal liver tests of unclear cause, with histology pointing to a specific diagnosis in 84% of patients. Although coagulation abnormalities continue to be an important concern when performing liver biopsy, their influence on complication risk remains unclear. Implementation of less stringent preprocedural coagulation thresholds decreased preprocedural transfusions without increasing the bleeding rate. Serious complications associated with percutaneous liver-biopsy (PLB) and transjugular liver-biopsy are similar, but pain appears to be more common with PLB. SUMMARY: Histopathological evaluation continues to be fundamentally important in assessing hepatic disease, and liver histology remains the most accurate approach to assess fibrosis and assign prognosis.

Pathology of liver disease: advances in the last 50 years.

Liver disease has been recognized in various forms for centuries. Incredible advances, however, have been made especially in the last 50 years, driven by improvements in histology, the development of immunostains, the development of high resolution imaging methods, improved biopsy and resection methods, and the emergence of the molecular era. With these tools, pathologists and their clinical and basic science colleagues moved from classifying liver disease using an observational, pattern-based approach to a refined classification of disease, one based on etiology for medical disease and tumor classification for neoplastic disease. Examples of liver specific diseases are used to illustrate these exciting advances. These impressive advances of the past provide the foundation for hope in the future, as liver pathology continues to play an important role in improving patient care through disease identification and classification and emerging roles in guiding therapy for cures.

Varying practices in tumor regression grading of gastrointestinal carcinomas after neoadjuvant therapy: results of an international survey.

Tumor regression grading is routinely performed on neoadjuvantly treated gastrointestinal cancer resections. Challenges in tumor regression grading include grossing standards, multiple grading systems, and difficulty interpreting therapy-induced changes. We surveyed gastrointestinal pathologists around the world for their practices in handling neoadjuvantly treated gastrointestinal cancer specimens and reporting tumor regression using a 23-question online survey. Topics addressed grossing, histologic work-up, tumor regression grading systems, and degree of difficulty identifying and estimating residual cancer within treatment effect. Two-hundred three responses were received, including 173 participants who completed the entire questionnaire. Fifty percent of the participants were from Europe, 29% from North America, 10% from Australia, and 11% from other continents. Ninety-five percent routinely report a tumor regression grade and 92% have standardized grossing and histologic work-up: 27% always completely embed the entire tumor bed, 54% embed the complete tumor site if not a grossly apparent, large mass. Fifty-nine percent use hematoxylin & eosin alone for assessment; the remaining use additional stains. In North America and Australia, the American Joint Committee on Cancer (AJCC)/College of American Pathologists (CAP)/Ryan system is routinely used for gastroesophageal (71%) and rectal carcinomas (77%). In Europe, the Mandard system is common (36%) for gastroesophageal tumors, followed by AJCC/CAP/Ryan (22%), and Becker (10%); for rectal CA, the Dworak system (30%) is followed by AJCC/CAP/Ryan (24%) and Mandard (14%). This regional differences were significant (p < 0.001 each). Fifty-one percent prefer a four-tiered system. Sixty-six percent think that regressive changes in lymph nodes should be part of a regression grade. Sixty-nine percent consider identifying residual tumor straight-forward, but estimating therapy-induced fibrosis difficult (57%). Free comments raised issues of costs for work-up and clinical relevance. In conclusion, this multinational survey provides a comprehensive overview of grossing and histologic work-up with regards to tumor regression grading in gastrointestinal cancers with partly significant regional differences particularly between North America and Europe.

The Kidney Biopsy in Systemic Lupus Erythematosus: A View of the Past and a Vision of the Future.

The kidney biopsy advanced our understanding of kidney disease in systemic lupus erythematosus. It allowed for better recognition and classification of lupus nephritis (LN). Several LN classifications have been devised in an effort to inform treatment decision and predict prognosis, and these are being further updated. In this review, we will examine the role of diagnostic as well as repeat kidney biopsy in the management of LN, including the potential role of molecular interrogation as a step forward beyond conventional histology to guide the discovery of novel biomarkers and a precision medicine approach to the management of LN.

Dissemination of health technologies: Trends in the use of diagnostic test in breast cancer screening.

OBJECTIVE: To analyse trends in the use of diagnostic test in breast cancer screening programs in Spain. MATERIALS AND METHODS: Retrospective study of 542,695 women who had undergone at least one screening mammogram in any of the screening centres of three administrative regions in Spain, between 1996 and 2011. Process measures were: overall recall rate, overall invasive test rate, and rates of each type of invasive test (fine-needle aspiration biopsy, core-needle biopsy and surgical biopsy). As results measures were included detection of benign lesions rate, ductal in situ cancer rate and invasive cancer rate. Adjusted by age rates were estimated year by year for each measure and, also, the annual percent of change and its corresponding joint points. RESULTS: Core-needle biopsy rates decreased between 1996 and 1999 and changed trends in 1999-2011 with an increase of 4.9% per year. Overall recall rate declined by 4.6% from 1999 to 2004, invasive test rate declined between 1996 and 2004 by 24.3%. Fine-needle aspiration biopsy rate changes were: a 22.4% declined per year (1996-1998), and 13.5% declined per year (1998-2005). Benign lesions rate decreased from 1996 to 2011, 21.4% per year (1996-2001) and 6.0% (2001-2011). Ductal carcinoma in situ and invasive cancer had no-statistically significant changes. CONCLUSION: The introduction of core-needle biopsy was slow and not concurrent with the reduction in the use of other diagnostic tests, but also represented a reduction in the rate of overall diagnostic tests and in the detection rate of benigns lesions without affecting the cancer detection rates.

Local Anesthesia With General Anesthesia for Pediatric Bone Marrow Procedures.

BACKGROUND: Pediatric patients with cancer undergo repeated painful procedures, including bone marrow aspirations and biopsies (BMABs). Optimal management of procedure-related pain can reduce discomfort, anxiety, and distress. METHODS: Children with neuroblastoma were randomly assigned to 1 of 2 arms on a prospective, single-blind, crossover trial conducted at Memorial Sloan Kettering Cancer Center from October 2016 to January 2018 (www.clinicaltrials.gov, identifier NCT02924324). Participants underwent 2 sequential BMABs: one with general anesthesia (GA) alone, the other with GA plus local anesthesia (LA) (GA + LA). The objective was to assess procedure-related pain and its interference with quality of life (QoL) with GA versus GA + LA. Primary outcome was percentage of participants requiring postprocedural opioids. Secondary outcomes were total opioid and nonopioid analgesics, pain scores, time to first analgesic, QoL, and toxicity. Management of postprocedural pain was standardized. RESULTS: Of 56 participants randomly assigned (3-16.5 years old), 46 completed both procedures. There was no significant difference in percentage of participants requiring opioids with GA versus GA + LA (24% vs 20%, P = .5). Pain scores in the recovery room were significantly lower for GA + LA versus GA (median [IQR]: 0 [0-2] vs 2 [0-4], P = .002). There were no statistically significant differences in total opioid or nonopioid analgesic, 6- and 24-hour pain scores, median time to first analgesic, or pain interference. No adverse events occurred. CONCLUSIONS: LA was associated with significant improvement in pain scores in the immediate recovery period. LA did not reduce postprocedural opioid use, nor did it improve QoL for patients undergoing BMAB with GA.
