RESUMO

The ablative radioiodine therapy of differentiated thyroid carcinoma Abstract. In the treatment of differentiated thyroid carcinoma, ablative radioiodine therapy holds a key role in curative intended therapy after total thyroidectomy and consideration of the appropriate indication. The benefit of ablation therapy extends from the completion of initial staging via post-therapeutic whole body scintigraphy via optimization of the value of thyreoglobuline measurement and implementation of dynamic risk stratification in follow-up care to decreasing the rate of tumor recurrence and mortality of thyroid cancer. Within this article, we discuss aims, indication, side reactions and specifics in preparation and execution of ablative radioiodine therapy.

RESUMO

PURPOSE OF REVIEW: This review evaluates more complex surgical procedures to see whether they might be suitable for ambulatory surgery. Operations that have shown an increasing daycase rate in England include thyroidectomy, joint arthroplasty, spinal surgery and hysterectomy, and these procedures are evaluated. Similarly, there have been recent developments in the management of nonelective ambulatory surgery with more timely throughput and home discharge for suitable patients. RECENT FINDINGS: Caveats on patient selection with the development of focussed educational programmes about the proposed operation have assisted with the development of shorter discharge times. Strict antiemetic guidelines, multimodal analgesic protocols and postoperative multidisciplinary follow-up are core components of the pathway for effective ambulatory management. Communication after discharge should include phone calls from the Ambulatory Unit and easy access to the medical staff who conducted their operation. SUMMARY: There should be no reason why more complex surgical operations could not be included in a day surgery armamentarium. Similarly, the evidence for more effective use of timely emergency care with shortened length of stay is increasing.

RESUMO

Over the past several years, there has been an increase in the discovery of thyroid cancers, likely because of the marked increased utilization of computed tomography (CT) and MR imaging. Despite the increase in number of thyroid cancers, the overall mortality remains unchanged because most of these cancers are the differentiated type and have a more indolent behavior. CT and MR imaging are important in the preoperative evaluation of thyroid goiters and thyroid cancer. This article discusses the imaging characteristics of benign and malignant thyroid diseases, and the important information that needs to be relayed to the surgeon.

RESUMO

Objective: To examine the feasibility of small drain in transoral endoscopic thyroidectomy vestibular approach (TOETVA). Methods: A prospective research was performed in Department of Oncology Plastic Surgery/Head and Neck Surgery, Hunan Cancer Hospital, from October 2018 to March 2019. Totally 103 patients who met the inclusion and exclusion criteria, signed the operation agreement of TOETVA, had their surgery completed and followed-up over 6 months, were enrolled in analysis. A central venous catheter was used as a drain tube in all cases (outer diameter 1.7 mm, inner diameter 1.0 mm). Visual analogue scale (VAS) was applied for assessing pain scores during the first 24 hours after the operation. Vancouver scar scale (VSS) was used for assessing the scar left by the drainage. The drainage volume (minimum scale:10 ml, approximate read: 1 ml) was recorded every 2 hours during the first postoperative 12 hours, every 4 hours during 12 to 24 hours, every 8 hours during 24 to 48 hours, and once from 48 hours until extubation. The volume of drainage, the cumulative volume and the percentage of cumulative volume accounting for the total volume were calculated. The data of residual volume (subtract the cumulative volume from the total volume) in the postoperative 24, 32 and 40 hours were analyzed, and their upper one-side P(95) was calculated by percentile method. Results: There were 12 males and 91 females. The age was (36.6±9.7) years (range: 18 to 58 years). The intraoperative tube-inserting time was (10.1±2.6) minutes (range: 6 to 18 minutes). The pain score on the first day was 2.7±1.1 (range: 1 to 5). The extubation time was (2.7±0.5) days (range: 2 to 4 days). VSS scores in the postoperative 1(st) month and 6(th) month were 2.9±1.3 (range: 0 to 7) and 0(2)(M(Q(R))), respectively. The size of the scar was 0 (2.5) mm in the postoperative 6(th) month. Sixty-four patients had no visible scars. There were 5 patients who had postoperative drain-related complications (1 for air leakage, 1 for tube blockage, 3 for subcutaneous hydrop, 2 for regional infection), who were all cured after proper treatment. The total volume of drainage for 98 patients without postoperative drain-related complications was (80.1±12.2) ml (range: 58 to 131 ml). The cumulative drainage within 8 hours accounted for (53.8±4.2)% (range: 41.0% to 62.9%) of the total drainage. The volume of residual fluids in the postoperative 32 hours was estimated to (5.8±2.7) ml (range: 0 to 12 ml,P(95)=10.0 ml). Conclusions: The small drain tubecan be applied in TOETVA, providing a satisfied cosmetic appearance and a reliable drainage. The main exudation period of the wound is within 8 hours after the operation. If a residual volume less than 10 ml is considered to be self-absorbable, the shortest safe extubation point for 95% patients without drain-related complications should be 32 hours after the operation.

RESUMO

The definition of substernal goiter (SG) is based on variable criteria, leading to considerable variations in the reported incidence (from 0.2% to 45%). The peri- and postoperative complications are higher in total thyroidectomy (TT) for SG than that for cervical goiter. This study aimed to evaluate the preoperative risk factors associated with postoperative complications.From 2002 to 2014, 142 (8.5%; 98 women and 44 men) of the 1690 patients who underwent TT had a SG. We retrospectively evaluated the following parameters: sex, age, histology, pre- and retro-vascular position, recurrence, and extension beyond the carina. These parameters were then related to the postoperative complications: seroma/hematoma, transient and permanent hypocalcemia, transient and permanent laryngeal nerve palsy, and the length of surgery. The results were further compared with a control group of 120 patients operated on in the same period with TT for cervical goiter (CG).Statistical analysis (Student t test and Fisher exact test) indicated an association between recurrence and extension beyond the carina with all postoperative complications. The group that underwent TT of SG showed a statistically significant higher risk for transient hypocalcemia (relative risk = 1.767 with 95% confidence interval: 1.131-2.7605, P = .0124, and need to treat = 7.1) and a trend toward significance for transient recurrent laryngeal nerve palsy (relative risk = 6.7806 with 95% confidence interval: 0.8577-53.2898, P = .0696, and need to treat = 20.8) compared with the group that underwent TT of cervical goiter. The major risk factors associated with postoperative complications are recurrence and extension beyond the carina.TT is the procedure to perform in SG even if the incidence of complications is higher than cervical goiters. The major risk factors associated with postoperative complications are recurrence and extension beyond the carina.

RESUMO

RATIONALE: Anaplastic thyroid carcinoma (ATC) is a rare highly aggressive thyroid malignancy. Thyroid sclerosing mucoepidermoid carcinoma with eosinophilia is also a rare low grade malignant thyroid neoplasm. To date, comorbidity of these 2 tumors in the thyroid gland has not been reported in the English literature. PATIENT CONCERNS: Here, we present a case of a 67-year-old women with a 6-month history of mass of left neck. She complained of a painless mass in the right neck. DIAGNOSES: Based on histopathological examination of H&E stained sections, immunohistochemical staining assay and molecular tests, the patient was diagnosed with ATC combined with sclerosing mucoepidermoid carcinoma with eosinophilia. INTERVENTIONS: The patient underwent radical surgery for thyroid cancer. OUTCOMES: No complications, local recurrence or metastases were observed during a 1 year and 3 months follow-up after surgery. LESSONS: To the best of our knowledge, this is the first case report on ATC combined with sclerosing mucoepidermoid carcinoma with eosinophilia in the English literature. This condition can be easily misdiagnosed during thyroid fine needle cytology. Clinicians should perform morphological examination, immunohistochemistry and molecular tests on resected specimen to make a definitive diagnosis.

RESUMO

The ability to identify patients with aggressive papillary thyroid microcarcinoma (PTMC) from the low-risk patients is critical to planning proper management of PTMC. Lymph node metastases showed association with recurrence and low survival rate, especially in patients with >5 or ≥2 mm metastatic lymph nodes. Therefore, this study aimed to investigate the preoperatively predictive factors of non-small-volume (metastatic lymph nodes >5 or ≥2 mm in size) central lymph node metastases (NSVCLNM) in PTMC patients. A total of 420 patients with clinically node-negative (cN0) PTMC without extrathyroidal extension underwent thyroidectomy plus central neck dissection (CND) between January 2013 and December 2015, were retrospectively analyzed. Of the 420 patients, 33 (7.9%) had NSVCLNM. The 5-year recurrence-free survival was significantly less in cN0 PTMC patients with NSVCLNM, when compared with patients without NSVCLNM (80.8% vs 100%, P < .001). Multivariate logistic regression revealed age ≤36 years (P < .001), male sex (P = .002), ultrasonic tumor sizes of >0.65 cm (P < .001), and ultrasonic multifocality (P = .039) were independent predictive factors of NSVCLNM. A prediction equation (Y = 1.714 × age + 1.361 × sex + 1.639 × tumor size + 0.842 × multifocality -5.196) was developed, with a sensitivity (69.7%) and a specificity (84.0%), respectively, at an optimal cutoff point of -2.418. In conclusion, if the predictive value was >-2.418 according to the equation, immediate surgery including CND rather than active surveillance might be considered for cN0 PTMC patients.

RESUMO

BACKGROUND: Thyroidectomy has been considered an effective method to treat thyroid cancer. However, about 20% of patients have psychological distress before surgery. Psychological distress is considered common mental illnesses and it has been reported that the patients who suffer psychological distress have poor clinical outcomes than the patients without psychosocial disorder. Therefore, we design this randomized controlled study to explore the effect of psychological nursing intervention against quality of life and psychological distress of the patients with thyroid cancer. METHOD: The trial will be conducted from September 2020 to December 2020 at Wuhan Fourth Hospital on the basis of the International Council for Harmonisation's Good Clinical Practice Guidelines and the principles of the Helsinki Declaration. The study was authorized via the Research Ethics Committee of the Wuhan Fourth Hospital (Approval number: 20200721-046). This study is a single-center, randomized, 2-arm, evaluator-blinded clinical trial. In all, 90 patients with thyroid cancer undergoing thyroidectomy will be enrolled in this study. The inclusion criteria includes: patients aged between 20 and 60 years old; ASA I-II classification; normal platelet coagulation and count function. The exclusion criteria contains: people with the intellectual and cognitive impairment (behavioral-cognitive intervention); BMI above 35 kg/m; the history of renal and hepatic dysfunction; and patients refuse to participate in this study. Both the patients in psychological intervention group and control group should receive the routine care, while the psychological intervention group also needs to receive the additional proper psychological nursing interventions. The emotional disorders are detected with the Chinese version of Profile of Mood States-Brief. And the patients' life quality is evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core Questionnaire (QLQ-C30, version 3.0). All the data are collated into Microsoft Excel 2010 and analyzed with SPSS 12.0 (IBM). RESULTS: It is assumed that psychological nursing intervention could alleviate the psychological distress of patients with thyroid cancer and improve their quality of life. CONCLUSION: This study can provide the reliable evidence regarding the influence of psychological nursing intervention against the life quality and psychological distress of the patients with thyroid cancer. TRIAL REGISTRATION: This study protocol is registered in Research Registry (researchregistry5937).

RESUMO

The importance of bedside assistants has been well established in various robotic procedures. However, the effect of assistants on the surgical outcomes of thyroid surgery remains unclear. We investigated the effects of a dedicated robot assistant (DRA) in robotic thyroidectomy. We also evaluated the learning curve of the DRA.Between January 2016 and December 2019, 191 patients underwent robotic total thyroidectomy, all of which were performed by a single surgeon. The DRA participated in 93 cases, while non-dedicated assistants (NRAs) helped with 98 cases. Demographic data, pathologic data, operative times, and postoperative complications were recorded and analyzed.Robotic thyroidectomy was successful in all 191 patients, and none required conversion to the conventional open procedure. Mean operative time was shorter in the DRA group than in the NRA group (183.2 ±â€Š33.6 minutes vs 203.1 ±â€Š37.9 minutes; P < .001). There were no significant differences in terms of sex distribution, age, preoperative serum thyroid stimulating hormone level, or pathologic characteristics between the groups. Cumulative summation analysis showed that it took 36 cases for the DRA to significantly reduce operative time. Mean operative time decreased significantly in the subgroup including the 37th to the 93rd DRA cases compared with the subgroup including only the first 36 DRA cases (199.7 ±â€Š37.3 minutes vs 172.8 ±â€Š26.4 minutes; P < .001). NRA group showed no definite decrease of operation time, which indicated that the NRAs did not significantly deviate from the mean performance.Increased experience of the bedside assistant reduced operative times in the robotic thyroidectomy. Assistant training should be considered as a component of robotic surgery training programs.

RESUMO

Background: Receptor-binding cancer antigen (RCAS1) is a membrane protein, regarded as a tumor-associated antigen. Cancer cells evade immune response with RCAS1 up-regulation, inducing apoptosis to tumor infiltrating lymphocytes. Thyroid cancer incidence is rising and its accurate diagnosis in early stage is targeted. The aim of this study is to access RCAS1 expression in benign and malignant thyroid pathology. Methods: This is a retrospective study of 110 patients, who had thyroidectomy in a single tertiary referral centre between January 2008 until December 2014. Immunohistochemistry study for RCAS1 expression was carried out and correlation with clinical and histopathological data is attempted. Results: RCAS1 immunostaining was found positive in 81 out of 110 cases. Notably it was deemed positive in all malignant thyroid tissue samples (p 0.001). In thyroid malignancy, tumor size, thyroid capsule invasion and positive lymph nodes status were positively correlated with moderate and strong expression of RCAS1. For papillary thyroid carcinoma, the vast majority (35/37 cases, 94.6%) were also classified as having moderate or strong RCAS1 expression. Conclusions: RCAS1 expression can aid in differential diagnosis between benign and malignant thyroid pathology, while its strong expression correlates with worse oncological features.

RESUMO

A 14 year-old girl with a previous medical history of cholecystic polyps was referred to our department with throat discomfort during swallowing. The cervical ultrasound and magnetic resonance imaging revealed a massive polycystic formation with a diameter of 45 × 24 × 31 mm consistent with a right lobe goiter. However, there were no findings for suspected malignancy. Hemithyroidectomy was performed and the specimen was sent for histopathological assessment. Hematoxylin-eosin staining of the right lower nodule showed variably-sized follicles consistent with adenomatous goiter. The right upper nodule showed a growth of relatively compact sized follicles with a thick fibrous capsule. A satellite nodule lying outside of the tumor capsule was consistent with minimally invasive follicular thyroid microcarcinoma. We observed her without any additional treatment and no recurrence is seen at present.

RESUMO

CONTEXT: Invited update on the management of systemic autoimmune Graves disease (GD) and associated Graves orbitopathy (GO). EVIDENCE ACQUISITION: Guidelines, pertinent original articles, systemic reviews, and meta-analyses. EVIDENCE SYNTHESIS: Thyrotropin receptor antibodies (TSH-R-Abs), foremost the stimulatory TSH-R-Abs, are a specific biomarker for GD. Their measurement assists in the differential diagnosis of hyperthyroidism and offers accurate and rapid diagnosis of GD. Thyroid ultrasound is a sensitive imaging tool for GD. Worldwide, thionamides are the favored treatment (12-18 months) of newly diagnosed GD, with methimazole (MMI) as the preferred drug. Patients with persistently high TSH-R-Abs and/or persistent hyperthyroidism at 18 months, or with a relapse after completing a course of MMI, can opt for a definitive therapy with radioactive iodine (RAI) or total thyroidectomy (TX). Continued long-term, low-dose MMI administration is a valuable and safe alternative. Patient choice, both at initial presentation of GD and at recurrence, should be emphasized. Propylthiouracil is preferred to MMI during the first trimester of pregnancy. TX is best performed by a high-volume thyroid surgeon. RAI should be avoided in GD patients with active GO, especially in smokers. Recently, a promising therapy with an anti-insulin-like growth factor-1 monoclonal antibody for patients with active/severe GO was approved by the Food and Drug Administration. COVID-19 infection is a risk factor for poorly controlled hyperthyroidism, which contributes to the infection-related mortality risk. If GO is not severe, systemic steroid treatment should be postponed during COVID-19 while local treatment and preventive measures are offered. CONCLUSIONS: A clear trend towards serological diagnosis and medical treatment of GD has emerged.

RESUMO

El estudio de las venas tiroideas no ha recibido una investigación tan exhaustiva como lo tuvieron las arterias tiroideas y los nervios laríngeos en relación a la cirugía tiroidea.De los tres pedículos venosos de la glándula tiroides, el medio, de lejos es el menos estudiado. La vena tiroidea media es inconstante y es el primer elemento vascular de la glándula tiroides que debe ser seccionado antes de luxar el lóbulo hacia medial para evaluar sus relaciones posteriores. Su lesión puede provocar sangrado intraoperatorio dificultando secundariamente la identificación del nervio laríngeo inferior y las glándulas paratiroides, próximas a la misma. Se realizó un estudio descriptivo de corte transversal evaluando la pesencia, número, simetría y asociación de la vena tiroidea media con variables tales como edad y sexo del paciente, así como la hiperfuncionalidad de la glándula tiroides y la presencia del tubérculo de Zuckerkandl en 100 tiroidectomías totales llevadas a cabo en el Instituto Nacional del Cáncer y en el Servicio de Otorrinolaringología del Hospital Central del Instituto de Previsión Social del Paraguay. La prevalencia global de vena tiroidea media fue del 74 %. En el lóbulo derecho, la vena se presentó en el 60 %, mientras que en el lóbulo izquierdo en el 53 %. En el 38 % se encontró la vena en ambos lóbulos. En 4 pacientes se localizaron venas tiroideas medias dobles, en una de ellas fue bilateral. El mayor porcentaje de las venas tiroideas medias se originó en el tercio medio del lóbulo, el 72 % en el lado derecho y el 70% en el izquierdo. No se encontró asociación entre la presencia de la vena tiroidea media y la edad, sexo, estado de hiperfunción glandular, así como tampoco con la presencia del tubérculo de Zuckerkandl.


The study of the thyroid veins has not received an investigation as extensive as the thyroid arteries and laryngeal nerves did in relation to thyroid surgery. Of the three veins pedicles of the gland the middle is far the least studied. This vein is inconstant and is the first vascular element of the gland that must be sectioned before the medial lobe is dislocated to evaluate ist posterior relationships. His injury can cause intraoperative bleeding, making it difficult to identify the inferior laryngeal nerve and the parathyroid glands, proximal to it. A descriptive crossseccional study was carried aot evaluating the presence, number, symmetricity and association of the middle thyroid vein with variables such as age and sex of the patient, as well as the hyperfunctionality of the gland and the presence of the Zuckerkandl tubercle in 100 total thyroidectomies undergoing at the National Cancer Institute and the ENT Service of the Social Security Institute´s Central Hospital. The overall prevalence of the middle thyroid vein was 74%. In the right lobe the vein appeared in 60% while in the left lobe in 53 %. Double middle thyroid vein was found in 4 patients, in one of them it was bilateral. The highest percentage of the middle thyroid veins originated in the middle third of the lobe, 72 % on the right and 70% on the left side. No association was found between the presence of the vain and age and sex, the state of glandular hyperfunstion, as well as the presence of Zuckerkandl tubercle.

RESUMO

Global widespread of current coronavirus disease 2019 (COVID-19) pandemic has emerged huge predicament to healthcare systems globally. This disease caused by a new beta-type coronavirus, known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), may lead to systemic multiorgan dysfunction syndrome and subsequently cause death due to abundant angiotensin converting enzyme 2 as its functional receptors throughout body. Oncology patients even have a worse prognosis with greater infection susceptibility because they are in a state of suppression of the systemic immune system due to malignancy and anticancer therapy. This problem makes adequate and appropriate treatment urgently needed. Through randomized clinical trials, various drugs were known to have good responses in COVID-19 patients. Here, we reported a-49-year-old-woman that was confirmed for COVID-19 by clinical manifestation, radiology profile, high procalcitonin concentration, and positive polymerase chain reaction (PCR) test. The patient also had breast and thyroid cancers history and had undergone various therapeutic modalities such as chemotherapy, thyroid surgery, and breast surgery. She was undergoing hormone therapy but experiencing disease progression after achieving complete remission based on PET-CT scan 4 months before. The patient was treated with various antibiotics but showed a significant clinical improvement by administering moxifloxacin.

RESUMO

Objective: The ultrasonographic scores EU TI-RADS and ACR TI-RADS were introduced to give the clinicians indications for fine needle aspiration cytology (FNAC). The predictive role of these scores was never evaluated and compared in a surgical series of patients. The aim of this study was to evaluate the ex post diagnostic accuracy of EU TI-RADS and ACR TI-RADS in a real-life series of thyroidectomized patients and to evaluate the 'missing' thyroid cancer following the operational indications of these scores. Design: Retrospective monocentric cohort study. Methods: In total, 255 patients (harboring 304 nodules) undergoing thyroidectomy for benign and malignant thyroid conditions were enrolled. The prevalence of thyroid malignancy for each class of ACR TI-RADS and EU TI-RADS, their diagnostic accuracy, the number of 'unnecessary' FNAC and the number of 'missed' cancers were evaluated. Results: ACR TI-RADS and EU TI-RADS score had similar and satisfactory accuracy values for predicting thyroid malignancy (AUC: 0.835 for ACR TI-RADS vs 0.827 for EU TI-RADS). The ACR TI-RADS and EU TI-RADS categories (suspicious vs non-suspicious), age, sex and presence of a single nodule significantly and independently predicted the presence of malignancy in a logistic regression model. An ex post analysis according to the indications for FNAC for each score indicated that 31 and 16 cases of cancer would have been missed by ACR TI-RADS and EU TI-RADS scores, respectively. Conclusions: ACR TI-RADS and EU TI-RADS display a good performance in predicting thyroid cancer when histology is taken as reference standard, but additional clinical judgement is required to decide the indication for FNAC.

RESUMO

BACKGROUND: The 2015 American Thyroid Association Management Guidelines for patients with thyroid nodules recommended a comprehensive sonographic evaluation of thyroid nodules' characteristics and the presence of any suspicious cervical lymph nodes (LNs) in the central and lateral compartments. This detailed sonographic assessment is still not routinely performed. We hypothesized that an endocrine surgeon-performed ultrasound (SUS) significantly enhances the management of thyroid cancer patients when compared with referral ultrasound (RUS). METHODS: We conducted a retrospective review of 267 consecutive thyroid surgery patients who were diagnosed with thyroid cancer on final pathology. All patients had undergone a SUS, but only 130 cohorts with both RUS and SUS were included. Features of thyroid nodules and LN and changes in the management plan were recorded. RESULTS: Based on SUS assessment, 26 patients (20%) were noted to have suspicious thyroid nodules which warranted a fine-needle aspiration (FNA) and were missed in RUS. On FNA, there were 12 patients with Bethesda categories III/IV and 14 patients with Bethesda V/VI. Those 26 patients were found to have a malignancy in the final pathology assessment. Thirty-eight patients (29.2%) were noted to have suspicious central/lateral neck findings on SUS but were not reported in RUS. Additionally, 8 patients (6.1%) were found to have a parathyroid adenoma by SUS and required concurrent parathyroidectomy. DISCUSSION: A comprehensive neck ultrasound in thyroid cancer patients, performed by their endocrine surgeon, could enhance management planning and outcomes. This finding highlights the critical need for education and improvement of routine neck ultrasonographic examination performed in the community.

RESUMO

Given the high incidence and excellent prognosis of many papillary thyroid microcarcinomas, the Porto proposal uses the designation papillary microtumor (PMT) for papillary microcarcinomas (PMCs) without risk factors to minimize overtreatment and patients' stress. To validate Porto proposal criteria, we examined a series of 190 PMC series, also studying sex hormone receptors and BRAF mutation. Our updated Porto proposal (uPp) reclassifies as PMT incidental PMCs found at thyroidectomy lacking the following criteria: (a) detected under the age of 19 years; (b) with multiple tumors measuring >1 cm adding up all diameters; and (c) with aggressive morphologic features (extrathyroidal extension, angioinvasion, tall, and/or hobnail cells). PMCs not fulfilling uPp criteria were considered "true" PMCs. A total of 102 PMCs were subclassified as PMT, 88 as PMC, with no age or sex differences between subgroups. Total thyroidectomy and iodine-131 therapy were significantly more common in PMC. After a median follow-up of 9.6 years, lymph node metastases, distant metastases, and mortality were only found in the PMC subgroup. No subgroup differences were found in calcifications or desmoplasia. Expression of estrogen receptor-α and estrogen receptor-ß, progesterone receptor, and androgen receptor was higher in PMC than in nontumorous thyroid tissue. BRAF mutations were detected in 44.7% of PMC, with no differences between subgroups. In surgical specimens, the uPp is a safe pathology tool to identify those PMC with extremely low malignant potential. This terminology could reduce psychological stress associated with cancer diagnosis, avoid overtreatment, and be incorporated into daily pathologic practice.
