Abstract
Tumors have long been compared to chronic wounds that do not heal, since they share many of the same molecular and cellular processes. In normal wounds, healing processes lead to restoration of cellular architecture, while in malignant tumors, these healing processes become dysregulated and contribute to growth and invasion of neoplastic cells into the surrounding tissues. Fibrocytes are fibroblast-like cells that differentiate from bone marrow-derived CD14+ circulating monocytes and aid wound healing. Although most monocytes will differentiate into macrophages after extravasating into a tissue, signals present in a wound environment can cause some monocytes to differentiate into fibrocytes. The fibrocytes secrete matrix proteins and inflammatory cytokines, activate local fibroblasts to proliferate and increase extracellular matrix production, and promote angiogenesis, and because fibrocytes are contractile, they also help wound contraction. There is now emerging evidence that fibrocytes are present in the tumor microenvironment, attracted by the chronic tissue damage and cytokines from both cancer cells and other immune cells. Fibrocytes may aid in the survival and spread of neoplastic cells, so these wound-healing cells may be a promising target for anticancer research in future studies.

A management strategy for giant cell tumor of the metacarpal: A single-center series of 11 cases. J Clin Orthop Trauma 2020; 11:657-661. [PMID: 32684706 PMCID: PMC7355077 DOI: 10.1016/j.jcot.2020.05.032] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Accepted: 05/26/2020] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Primary giant cell tumor (GCT) arising from bones of hand are rare to occur. Metacarpals are often the most common site of involvement among hand bones. There are no uniform guidelines for treatment of GCT involving metacarpals due to lack of relevant literature. OBJECTIVE To suggest a management strategy for GCT involving metacarpals. METHODS Retrospective review of cases of GCT involving metacarpals over a period of 15 years from 2005 to 2019 managed at department of Orthopaedics, All India Institute of Medical Sciences, New Delhi. RESULTS A total of 12 cases of GCT involving metacarpal were included, out of which one was lost to follow-up. Four cases were recurrent, and seven were primary at the time of surgery. All the patients were operated with wide excision of the tumor. In seven patients reconstruction of the metacarpal and MCPJ was done using fibular strut graft and silastic artificial joint, while in two patients, MCPJ arthrodesis was performed using fibula and/or iliac crest bone graft. In another two patients, the MCPJ was reconstructed using reversed vascularised toe transfer. Mean follow up of the patients was 3.22 ± 2.07 years. Mean Quick DASH score at latest follow-up of patients operated with silastic joint reconstruction, reversed vascularised toe transfer and arthrodesis of MCP joints were 30.5 ± 9.5, 25 ± 2.3 and 39.8 ± 3.4 respectively. Local recurrence occurred only in one patient at one year after surgery. All the patients were pain free at latest follow-up with quite functional and cosmetically acceptable hand. CONCLUSION Reversed vascularised metatarsal transfer has obtained better functional results compared to reconstruction with fibular grafting and silicone joint replacement but due to technical difficulties, vascularised joint transfer may not be performed in every setting and there is risk of donor site morbidities with this technique. Our strategy for the treatment of GCT involving metacarpal was to do vascularised joint transfer or arthrodesis for border digits and reconstruction with silicone joint for central digits.

Abstract
INTRODUCTION Myxoid soft tissue tumors consist of a heterogeneous group of mesenchymal neoplasms with a hallmark of the abundant extracellular myxoid matrix. Intramuscular myxomas are rare benign tumor affecting the musculoskeletal system. The common sites include the thigh, upper arm, calf, and the buttocks. Magnetic resonance imaging is the radiological modality of choice in diagnosing these cases, while tissue biopsy is the gold standard. CASE PRESENTATION A 70-year-old male presented to orthopedics out-patient department with complaints of a humongous swelling engulfing his right thigh all around. The gradual and progressive appearance of burning sensations and rest pain around the affected area with difficulty in bearing weight, over the past 6-7 months forced him to seek medical attention. Biopsy and imaging were performed followed by final excision. The tumor was removed En-bloc and post-operative period was uneventful. The patient did not show any signs recurrence and was asymptomatic until the final followup of 26 months. CONCLUSION Myxomatous swelling mimics an intramuscular lipoma, sarcoma, hematoma, or a hemangioma and must be carefully evaluated. En-bloc excision without spillage is the treatment of choice which ensures long and lasting recovery.

Abstract
BACKGROUND Meningioma is an intracranial tumor frequently encountered in the neurosurgical setting. Extracranial disease is a rare occurrence, with a reported incidence in 0.1% of cases. Metastasis is associated with previous craniotomy, venous sinus invasion, local recurrence, and World Health Organization (WHO) grade III tumor. Metastasis of a benign, grade I meningioma is extraordinarily rare. CASE DESCRIPTION We report a case of a 41-year-old with a WHO grade I intracranial meningioma that had invaded and occluded the superior sagittal sinus. Chest computed tomography (CT) scan revealed pulmonary nodules, which were biopsied and confirmed benign meningioma. The metastatic meningiomas were found before resection of the primary tumor, suggesting direct seeding through the venous system versus iatrogenic seeding. Thirteen years later, an additional lung mass was found incidentally on abdominal CT scan for workup of a sarcoidosis. Biopsy and subsequent resection confirmed benign meningioma. A retrospective review of earlier chest CT scans revealed a small lesion that corresponded to the larger lesion found 13 years later. CONCLUSIONS This a rare case of a WHO grade I meningioma involving the sagittal sinus with direct seeding of the pulmonary vascular bed leading to multiple meningioma metastases. The report highlights an increased risk of distant metastases for a benign meningioma with invasion of dural sinuses.

Primary Epithelial Minor Salivary Gland Tumors in South Africa: A 20-Year Review. Head Neck Pathol 2019; 14:715-723. [PMID: 31873932 PMCID: PMC7413971 DOI: 10.1007/s12105-019-01111-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Accepted: 12/02/2019] [Indexed: 10/25/2022]
Abstract
Minor salivary gland tumours represent 9-25% of all salivary gland tumours. South African epidemiological reports on minor salivary gland tumours are lacking. This study aims to evaluate the frequency, epidemiology and histology of minor salivary gland tumours in a defined South African population from 1997 to 2016. This cross sectional retrospective review of epithelial minor salivary gland neoplasms recorded patient demographic data: prevalence, age, gender, site, histology. There were 553 benign (57%) and malignant (43%) minor salivary gland tumours, in patients between the ages of 9 and 93 years. There was no significant age (p = 0.64) or gender (p = 0.18) difference between males and females. Common histologic types of salivary gland tumours in the continually evolving spectrum were pleomorphic adenoma (52%), adenoid cystic carcinoma (12%) and mucoepidermoid carcinoma (10%). Common sites were the palate (56%), cheek (11%), lip (9%) and paranasal sinuses (7%). Minor salivary gland tumours represent 2.3% of head and neck pathology. Although this prevalence is higher than reported, there is no overall increase in number diagnosed per year. Minor salivary gland tumours were more prevalent in females. Benign tumours occurred at a younger age than malignant tumours. This study serves as a baseline for future studies, especially in South Africa.

Diagnostic performance of diffusion and perfusion MRI in differentiating high from low-grade meningiomas: A systematic review and meta-analysis. Clin Neurol Neurosurg 2019; 190:105643. [PMID: 31865221 DOI: 10.1016/j.clineuro.2019.105643] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 12/13/2019] [Accepted: 12/15/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVES The purpose of the present meta-analysis and systematic review was to evaluate the currently published data on the potential role of perfusion (PWI) and diffusion (DWI) weighted imaging for the assessment of meningioma grade. PATIENTS AND METHODS A search of MEDLINE and relative reference lists was conducted to identify all the eligible studies assessing the diagnostic performance of DWI and PWI in grading meningiomas. Meta-Disc and Rev-Man were used for the statistical analysis. Methodological quality and risk of bias were assessed with the use of the updated Quality assessment of the diagnostic accuracy (QUADAS-2) tool. Pooled sensitivity, specificity and area under the summary receiver operating characteristic curve were calculated individually for DWI and PWI to demonstrate the diagnostic performance of each modality. RESULTS Fourteen studies with 1063 patients were included. The 8 studies evaluating DWI showed a pooled sensitivity of 80% (95% CI, 74%-86%) and a pooled specificity of 76% (95% CI, 72%-79%). As for the 6 remaining studies concerning PWI, the pooled sensitivity and specificity were found 80% (95% CI, 71%-88%) and 91% (95% CI, 87%-94%), respectively. The area under the SROC curve was 0.94 (95% CI) for PWI and 0.91 (95% CI) for DWI. The comparison of the two AUCs showed that neither technique was superior with regards to the diagnostic performance. CONCLUSIONS The current evidence proves that both techniques are efficient at differentiating high from low-grade meningiomas.

Abstract
OBJECTIVE To determine the clinical characteristics and treatment results of benign and malignant tumors of the hard palate in our hospital. PATIENTS AND METHODS A total of 25 patients who underwent surgical treatment for hard palate tumors between 2008 and 2018 were included in this study. Their demographic characteristics, smoking status, alcohol consumption, symptoms, duration of symptoms, size and localization of hard palate tumor, status of mucosal surface, radiologic examinations, surgery, reconstruction method, histopathologic results, treatment outcomes, oral intake start time, adjuvant treatment, postoperative complications, and recurrence were reviewed. RESULTS Of the 25 patients with hard palate tumors, 15 (60.0%) had benign tumors and 10 (40.0%) had malignant tumors. Both benign and malignant tumors of the hard palate occurred more frequently in females than in the males. The most common symptom of hard palate tumor was palate mass. The most common benign tumor was pleomorphic adenoma (n = 13). The most common malignant tumors were squamous cell carcinoma and carcinoma ex pleomorphic adenoma (n = 3 for each). All patients were operated via transoral approach without external incision. We did not experience any recurrence in this study. The oral intake start time was late in malignant hard palate tumors (p < 0.05). CONCLUSION The comparison of clinical features of benign and malignant hard palate tumors showed a statistical significance only for oral intake start time. Transoral surgical removal with clear margin is a safe and effective procedure for benign and malignant hard palate tumors.

Abstract
Pilomatrixoma or calcifying epithelioma of Malherbe is a benign skin tumor arising from the hair follicle; breast occurrence is considered a rarity. Clinically presenting as a palpable abnormality and with both benign and malignant mammographic and sonographic features, it can be easily misdiagnosed as a breast neoplasm. We report a very rare case of pilomatrixoma of the male breast in a 36-year-old male presenting with a firm, superficial nodule in the upper outer quadrant. Though the sonographic trifecta of imaging features (shape- margins-orientation/oval, circumscribed mass, parallel to the skin) is consistent with a benign lesion, a histologic diagnosis was warranted based on its most suspicious feature of internal pleomorphic calcifications. Pathologic diagnosis revealed the uncommon benign entity of pilomatrixoma in the male breast. Our patient was recommended for surgical excision based on current literature recommendations for management in most reports of pilomatrixoma. One alternative recommendation presented in a single report of pilomatrixoma in the breast supported follow-up imaging based on benign imaging characteristics.

Abstract
STUDY OBJECTIVE To compare the feasibility of opportunistic bilateral salpingectomy (OBS) at the time of vaginal hysterectomy (VH) for benign disease in patients with and without relative contraindications (RCs) to the vaginal approach and to evaluate the factors that contribute to the inability to perform OBS. DESIGN Retrospective chart review. SETTING Tertiary medical center. PATIENTS Women undergoing hysterectomy for benign indications between November 2014 and October 2017 who were consented for either VH with or without removal of tube(s) and/or bilateral salpingectomy. INTERVENTIONS RCs to the vaginal approach are defined as lack of prolapse (cervix high, cervix not visualized, cervix tucked underneath pubis, or minimal descent), enlarged uterus (≥250 g or a size of a ≥12-week uterus), nulliparity, obesity (body mass index ≥30 kg/m2), previous cesarean section (CS), known adhesions, and known adnexal pathologic condition. MEASUREMENTS AND MAIN RESULTS A total of 258 patients underwent VH and attempted to undergo OBS within the study period; of these, 112 patients (43.4%) had no RC, and 146 patients (56.6%) had ≥1 RCs. Overall, successful salpingectomy was performed in 86.8% of patients. There was no significant difference in the rate of success in patients without or with ≥1 RCs (84.9% vs 89%, p = .15). Salpingectomy was unsuccessful in 13.2% of patients (n = 34). In a multivariable logistic regression analysis, the odds of unsuccessful OBS were 3.83 times higher in patients without prolapse (confidence interval [CI], 0.99-14.76; p = .051), 2.71 times higher in patients with obesity (CI, 1.23-5.94; p = .013), and 3.07 times higher in patients with previous CS (CI, 1.17-8.08; p = .023) as compared to patients without any relative contraindications. An enlarged uterus was associated with successful salpingectomy (odds ratio, 0.28; 95% CI, 0.08-0.94; p = .039) compared with a normal-sized uterus. When excluding enlarged uterus, patients with 2 to 3 RCs had 11.24 and 6.8 higher odds of an unsuccessful OBS than patients with no (CI, 3.73-33.87; p <.001) and 1 RC (CI, 2.36-19.63; p <.001), respectively. There were no differences in postoperative stay or rates of readmission among patients with or without successful salpingectomy at the time of VH. CONCLUSION OBS is associated with a high overall rate of success in patients with and without traditional RCs to VH. Lack of prolapse, obesity, and previous CS were associated with failed attempt at salpingectomy. Patients with ≥2 RCs to VH should be counseled about the high likelihood of failed salpingectomy.

Abstract
STUDY OBJECTIVE To evaluate the diagnostic performance of the Decision Tree System (DTS) rules 2 and 3 for surgically managed adnexal masses in the North American population and to compare it with the risk stratification criteria used at The Hospital for Sick Children (≥8 cm and complex/solid). DESIGN A retrospective cohort study of patients who presented with adnexal masses and were surgically treated between April 2011 and March 2016. SETTING The Hospital for Sick Children (Toronto, Ontario, Canada). PARTICIPANTS Patients 1-18 years of age with adnexal masses who underwent surgical treatment. INTERVENTIONS AND MAIN OUTCOME MEASURES Main outcome measures included diagnostic performance (preoperative sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV] for malignancy) of the DTS rules 2 and 3 and ≥8 cm and complex/solid criteria. RESULTS The malignancy rate was 10.4%. The DTS rules 2 and 3 had a sensitivity of 84% (95% confidence interval [CI], 79-90), specificity of 77% (95% CI, 71-83), PPV of 30% (95% CI, 17-42), and NPV of 98% (95% CI, 94-100). The 8 cm or larger and complex/solid criteria had a sensitivity of 89% (95% CI, 85-94), specificity of 71% (95% CI, 64-77), PPV of 27% (95% CI, 16-38), and NPV of 98% (95% CI, 96-100). CONCLUSION Our study showed that DTS rules 2 and 3 had similar diagnostic performance as the 8 cm or larger and complex/solid criteria in the same population, with a very high NPV and a low PPV. Future prospective investigations should be conducted to further assess how DTS components can be incorporated into future algorithms for the management of adnexal masses in the pediatric population.

Abstract
Background & Objective: Malignant breast tumors, which are one of the most important deadly cancers in women, like many other cancers, are proposed to be related to viruses etiologically. Proper management of breast carcinoma necessitates an identification of the etiological factors. Human Papillomavirus is considered to have an etiological role in breast carcinoma. We carried out this study to find out if Human Papillomavirus-DNA is present in the malignant and benign breast tissue in our patients. Methods: Seventy-five paraffin-embedded breast cancer tissues and 75 normal breast tissues and benign breast lesions were examined in this study (case-control) to look for Human Papillomavirus-DNA employing Nested Polymerase Chain reaction. The tissues were examined over a period of ten years in the pathology department of the Pathobiology Laboratory Center of Tehran. Results: No Human Papillomavirus-DNA was found in any of the malignant or control group specimens. Conclusion: Our results showed no evidence of Human Papillomavirus in cancerous and benign tissues, which is consistent with some other studies in English medical literature. More investigations using more specimens from different parts of the country are required to confirm the presence or absence of any connection between Human Papillomavirus and development of breast carcinoma in Iran.

Abstract
Salivary gland diseases usually present as a swelling of the affected gland. These lesions are commonly encountered in day to day practice. A salivary gland swelling can present in a variety of locations, depending on the salivary gland affected. The purpose of the study is to know the incidence of salivary gland swellings and the usefulness of FNAC in evaluating these swellings. The present study is a time bound prospective study of fifty consecutive cases of salivary gland swellings admitted in our hospital during the period November 2014-August 2016. Most of the patients underwent pre-operative work up with FNAC and patients indicated for surgery underwent surgery and HPE. Salivary gland swelling occurred more commonly in 3rd decade of life and equal number of cases were seen in both genders. Most of the patients presented with salivary gland swelling (98%). 21 (42%) were non neoplastic, 29 (58%) were neoplastic swellings, 18 (36%) were benign of which pleomorphic adenoma was the most common and 11 (22%) were malignant of which adenoid cystic carcinoma was the most common. Parotid gland was the most common gland involved. Fine needle aspiration cytology was highly sensitive for benign tumours and highly specific for malignant tumours. FNAC should be first choice of investigation in evaluating the salivary gland pathologies. Early diagnosis and subsequent appropriate management carries good prognosis.

Abstract
Benign and malignant neoplasm of oral cavity is usually presented as swellings or ulcerations of affected tissue. The lesions are broadly categorized as potentially malignant disorders, benign and malignant neoplasm of epithelial and connective tissue origin for the convenience of learning. Neoplasm of oral cavity has a significantly lower incidence. Because of uncommon occurrence of oral neoplasm, retention of diagnostic skills is a challenging task. However, comprehensive understanding on clinical and pathologic details will help in correlating and presenting complaint and assisting in formulation of possible diagnosis. The key for successful therapeutic management depends on achieving right and timely diagnosis.

Abstract
BACKGROUND Radiation Therapy (RT) is an established treatment option for benign intracranial lesions. The aim of this study is to display an update on the role of RT concerning the most frequent benign brain lesions and tumors. METHODS Published articles about RT and meningiomas, Vestibular Schwannomas (VSs), Pituitary Adenomas (PAs), Arteriovenous Malformations (AVMs) and craniopharyngiomas were reviewed and extracted data were used. RESULTS In meningiomas RT is applied as an adjuvant therapy, in case of patientrefusing surgery or in unresectable tumors. The available techniques are External Beam RT (EBRT) and stereotactic ones such as Stereotactic Radiosurgery (SRS), Fractionated Stereotactic RT (FSRT), Intensity Modulated RT (IMRT) and proton-beam therapy. The same indications are considered in PAs, in which SRS and FSRT achieve excellent tumor control rate (92-100%), acceptable hormone remission rates (>50%) and decreased Adverse Radiation Effects (AREs). Upon tumor growth or neurological deterioration, RT emerges as alone or adjuvant treatment against VSs, with SRS, FSRT, EBRT or protonbeam therapy presenting excellent tumor control growth (>90%), facial nerve (84-100%), trigeminal nerve (74-99%) and hearing (>50%) preservation. SRS poses an effective treatment modality of certain AVMs, demonstrating a 3-year obliteration rate of 80%. Lastly, a combination of microsurgery and RT presents equal local control and 5-year survival rate (>90%) but improved toxicity profile compared to total resection in case of craniopharyngiomas. CONCLUSION RT comprises an effective treatment modality of benign brain and intracranial lesions. By minimizing its AREs with optimal use, RT projects as a potent tool against such diseases.

Abstract
Objective We aimed to compare the incidence of parotid tumors seen in our region in the last ten years with the literature values and to compare the recently proposed new parotidectomy methods with classical parotidectomy methods which we applied for ten years. Materials and Methods 37 females and 36 males total 73 patients who made parotidectomy between 2008 and 2018 were included in the study. The patients age, sex, histopathological diagnosis, surgical methods applied to malignant or benign tumors and side of the disease were recorded. Histopathological results and the results of surgical methods applied were compared with literature. Results The mean age of the 73 patients underwent parotidectomy was 54±34. Of the cases, 57 (78%) cases were benign and 16 (22%) were malignant. Histopathologically benign masses were found 3.5 time more common than malignant masses. The sides of diseases were observed at the near rates (right, left; 52%, 48%, respectively). The most often detected benign neoplasm was pleomorphic adenoma with 42 (74%) cases. The most often detected malignant neoplasm was mucoepidermoid carcinoma with 6 (43%) cases. As surgical method, superficial parotidectomy was applied to 64 (88%) patients, total parotidectomy to 9 (12%) patients and the neck dissection to 7 (10%) patients. Conclusion We recommend that to be applied the superficial parotidectomy as the smallest procedure to be performed in the surgery of parotid tumors and to be avoided from partial superficial parotidectomies. In short, we advocate to classical methods for the parotid tumor surgery.

Abstract
Keratoacanthoma (KA) is a self-limiting benign epithelial neoplasm. It occurs predominantly on sun-exposed areas of the body and is believed to arise from hair follicle. It shows a unique behavior in being clinically benign and microscopically malignant. Earlier it was considered as a pseudomalignant lesion but now it is believed to be pseudobenign in nature. The most common concern is related to its nosological position at the border of malignancy and benignity. We hereby report a rare case of keratoacanthomatous type of squamous cell carcinoma in an elderly female showing aggressive nature of the lesion. The various terminologies used for KA in the past have also been tabulated.

Increased Risk of Incident Disease in Men with Peyronie's Disease: Analysis of U.S. Claims Data. J Sex Med 2019; 15:894-901. [PMID: 29803352 DOI: 10.1016/j.jsxm.2018.04.640] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 03/26/2018] [Accepted: 04/13/2018] [Indexed: 11/23/2022]
Abstract
BACKGROUND The subsequent health risks associated with Peyronie's disease (PD) are unknown. AIM This cohort study assesses the risk of developing auto-immune conditions and common chronic health conditions after a diagnosis of PD. We hypothesize that an increase in auto-immune disease will be evident in men with PD, as has been suggested in smaller studies. METHODS We determined the longitudinal incidence of 13 auto-immune diseases and 25 common chronic conditions in a cohort from the Truven Health Analytics (Ann Arbor, Michigan, USA) database from 2007-2013. The cohort included men with 1 of 3 exposures in 2007: (1) men with PD, (2) men with erectile dysfunction (ED) but not PD, and (3) men without PD or ED, matched on age and follow-up duration. OUTCOMES To assess incidence, we utilized a Cox regression model adjusting for age, smoking, obesity, health care visits per year, urology visits per year, and years of follow-up. RESULTS We included 8,728 men with PD; 204,147 men with ED; and 87,280 controls. Men with PD had an increased risk of developing benign prostatic hyperplasia (hazard ratio [HR] 1.21, 95% CI 1.16-1.27), prostatitis (HR 1.21, 95% CI 1.12-1.31), and lower urinary tract symptoms (HR 1.10, 95% CI 1.05-1.16) when compared to both men with ED and age-matched controls without ED or PD even when controlling for the number of urology visits per year. Compared to controls, men with PD also had an increased risk of developing keloids. No significant risk for any auto-immune disease was observed. CLINICAL IMPLICATIONS Clinicians should have heightened awareness for these relevant co-morbidities when treating men with PD. STRENGTHS & LIMITATIONS Utilizing a claims database provides one of the largest cohorts of men with PD ever published but claims databases lack some individual patient data such as risk factors and demographic information relevant to PD, including: penile injury, history of urologic procedures, and other lifestyle factors. CONCLUSION Men with PD had a higher risk of benign prostatic hyperplasia, lower urinary tract symptoms, prostatitis, and keloids after a diagnosis of PD, but no increased risk of auto-immune conditions. These findings suggest a common etiology for these conditions that may manifest itself in diseases at different times in men's life cycle. Pastuszak AW, Rodriguez KM, Solomon ZJ, et al.

Relationship between plasma Atherogenic index and final pathology of Bosniak III-IV renal masses: a retrospective, single-center study. BMC Urol 2019; 19:85. [PMID: 31519200 PMCID: PMC6743186 DOI: 10.1186/s12894-019-0514-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Accepted: 08/29/2019] [Indexed: 12/16/2022] Open
Abstract
Background There is an increased incidence of renal cell carcinoma (RCC) in patients with metabolic syndrome who usually have high levels of serum triglyceride (TG) and low high-density lipoprotein-cholesterol (HDL-C). Plasma atherogenic index (PAI) is the logarithmic ratio of serum TG level to HDL-C and related to cardiovascular diseases. In this study, we aimed to determine the accuracy of PAI in determining renal malignancy in localized renal masses preoperatively. Methods Totally 169 patients who were diagnosed with Bosniak III-IV lesions by imaging modalities and treated in our hospital with partial or radical nephrectomy were retrospectively analyzed using institutional renal cancer database between 2013 and 2018. Preoperative images were evaluated by two experienced radiologists. The patients were divided into two groups according to their postoperative pathological diagnosis as malignant or benign tumors. The PAI of each patient was calculated and the statistical significance of PAI in predicting malignancy for renal masses was analyzed using uni- and multivariable analyses. Results Of patients, 109 (64.5%) were males and 60 (35.5%) were females with a median age of 61 (33–84) years. Median tumor size was 6.5 (2–18) cm. Pathological diagnosis was malignant in 145 (85.8%) and benign in 24 (14.2%) patients. There was no statistically significant difference in serum TG levels between malignant and benign cases (p > 0.05). The HDL-C levels were significantly lower in malignant cases (p = 0.001). Median PAI value was 0.63 (0.34–1.58) and significantly higher in malignant cases (p = 0.003). The PAI cut-off value for malignancy was ≥0.34. The sensitivity was calculated as 88.2% and specificity as 45.8%, the positive predictive value as 90.8, negative predictive value as 39.3, and odds ratio as 6.37 (95% CI: 2.466–16.458). In multivariable analysis, gender, smoking status, and hypertension had no effect on malignancy, whereas PAI and HDL-C were independent risk factors (p = 0.003 and p = 0.003, respectively). The risk of malignancy was 5.019 times higher, when PAI was > 0.34 (95% CI: 1.744–14.445) in multivariable logistic regression analysis. Conclusions The PAI can be used as a predictive tool in suspicion of malignant renal masses. In case of a benign pathology, PAI levels may be encouraging for surgeons for nephron-sparing surgery.

Abstract
The accurate diagnosis of a liver mass can usually be established with a thorough history, examination, laboratory inquiry, and imaging. The necessity of a liver biopsy to determine the nature of a liver mass is rarely necessary. Contrast-enhanced computed tomography and magnetic resonance are the standard of care for diagnosing liver lesions and high-quality imaging should be performed before performing a biopsy. This article discusses current consensus guidelines for imaging of liver masses, as well as masses found on surveillance imaging. The ability to accurately characterize lesions requires proper use and understanding of the technology and expert interpretation.

Abstract
In the past decade, remarkable progress has been made in reprogramming terminally differentiated somatic cells and cancer cells into induced pluripotent cells and cancer cells with benign phenotypes. Recent studies have explored various approaches to induce reprogramming from one cell type to another, including lineage-specific transcription factors-, combinatorial small molecules-, microRNAs- and embryonic microenvironment-derived exosome-mediated reprogramming. These reprogramming approaches have been proven to be technically feasible and versatile to enable re-activation of sequestered epigenetic regions, thus driving fate decisions of differentiated cells. One of the significant utilities of cancer cell reprogramming is the therapeutic potential of retrieving normal cell functions from various malignancies. However, there are several major obstacles to overcome in cancer cell reprogramming before clinical translation, including characterization of reprogramming mechanisms, improvement of reprogramming efficiency and safety, and development of delivery methods. Recently, several insights in reprogramming mechanism have been proposed, and determining progress has been achieved to promote reprogramming efficiency and feasibility, allowing it to emerge as a promising therapy against cancer in the near future. This review aims to discuss recent applications in cancer cell reprogramming, with a focus on the clinical significance and limitations of different reprogramming approaches, while summarizing vital roles played by transcription factors, small molecules, microRNAs and exosomes during the reprogramming process.

Abstract
This work aimed to characterize normal, benign and malignant excised breast tissues through the analysis of the FTIR spectra of their plasma membrane proteins. Tissue characterization parameters such as peak position, peak intensity, area under the peak, relative peak intensity and relative area under peak were evaluated mainly for protein spectral peaks; 1150 cm-1, Amide I, Amide II, Amide III, and Amide A. The sensitivity, specificity and diagnostic accuracy for each parameter were obtained and Receiver Operating Characteristic (ROC) Curves were plotted. Results showed significant spectral differences between normal and benign tissues compared to malignant tissues at 1536 and 1645 cm-1. The three tissues could be distinguished at 2900 cm-1, where the malignant peak uniquely split into two separate peaks. ROC curves showed that the Amide A peak position yielded a higher accuracy compared to all other investigated characterization parameters. The deconvolution of Amide I revealed the conformational changes in plasma proteins characterizing the transformation to malignancy (a decrease in the percentage of alpha helix accompanied by an increase in the percentage of beta sheets). The use of the present structure-based analysis in conjunction with histopathological examination of excised breast tissues would offer an enhanced characterization that might reduce possible personal diagnostic mistakes.

Abstract
Stromal tumour of Undetermined malignant potential (STUMP) of the prostate is a rare tumour arising from the prostate specialized stroma. The patient presented with LUTS, MRI showed prostatic growth, and biopsy showed no malignancy. The symptoms were treated by TURP and 11 g were removed of the prostate. The tumour recurred within less than a year to three times its original size. It is the first time in literature, HoLEP was used to remove the origin of the tumour successfully.
Introduction Stromal Tumour of Undetermined malignant potential (STUMP) is a rare category of the prostate benign tumours, which has a variable clinical presentation, behavior and different approaches to manage it. Case presentation A 57 year-old male presented with voiding symptoms of the urinary tract and an increased PSA (14.7 ng/ml). Ultrasound and multiparametric MRI showed an enlarged prostate of 41 ml. Transurethral resection of the prostate (TURP) was performed with 11 g benign tissue removed. The patient presented one year later with the same symptoms; further ultrasound and parametric MRI demonstrated huge recurrence in the transition zone with a new prostate size of 131 ml. Discussion Despite no malignancy being identified in the initial TURP histology, the transition zone prostatic tumour behaved aggressively and recurred in just one year. For the first time in literature, the tumour recurred rapidly to three times the initial size and was removed using Holmium Laser enucleation of the prostate (HoLEP), after which no recurrence was seen in 11 months period. Conclusion HoLEP can be used to successfully enucleate STUMP tumours but the clinical behavior of the STUMP in prostate is still not understood well because of its rareness.

Abstract
Lactating adenoma is an uncommon palpable breast lesion occurring in the late pregnancy or lactation period and is commonly found in young primiparous women in the second or third decade of life. Although a benign condition, sometimes, core biopsy is required to exclude malignancy. Approximately 3% of all breast cancers occur in women who are pregnant; and hence, a breast mass in this group of women must be investigated. The main differential diagnosis for a palpable solid breast mass is lobular hyperplasia which is a normal physiological event, fibroadenoma, focal mastitis, lactating adenoma, tubular adenoma, phyllodes tumor, and breast carcinoma. Here, we present a case of lactating adenoma of the breast at 6 months’ postpartum in a 24-year-old primiparous woman.
