    Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign (fibroadenoma) or malignant pathologic processes. Less than forty cases of fibroadenomas have been reported in the literature. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare. Only four cases have been reported. We report a case of a young woman who presented with vulvar mass during her lactation. The mass was excised, and histology confirmed vulvar lactating adenoma associated with fibroadenoma. This is the first case of vulvar heterotopic breast lesion associating lactating adenoma and fibroadenoma.

    Ectopic breast tissue is defined as glands located outside of the breast. It can be found anywhere along the milk line extending from the axilla to the groin, and can occur in the vulva. Ectopic breast tissue should be excised because it may develop benign or malignant pathologic processes. Less than 40 cases of fibroadenoma in the vulva have been reported in the literature. We report a case of a 37-year-old woman presenting a solitary vulvar mass. The mass was excised completely, and histology demonstrated an ectopic breast fibroadenoma. This is one of the few reports on the benign pathologies of vulvar mammary glands.

    2017-01-01

    Background: Patients with vulvar neoplasms report a lack of information, missing support in self-management and a gap in delivery of health care. Aim: The aim of the study was to investigate if written information or counseling based on the WOMAN-PRO II program are able to improve patient satisfaction and the delivery of health care from the health professional's perspective of women with vulvar neoplasms. Method: Patient satisfaction and the delivery of health care have been investigated as two secondary outcomes in a multicenter randomized controlled parallel-group phase II study (Clinical Trial ID: NCT01986725). In total, 49 women, from four hospitals (CH, AUT), completed the questionnaire PACIC-S11 after written information (n = 13) and counseling (n = 36). The delivery of health care was evaluated by ten Advanced Practice Nurses (APNs) by using the G-ACIC before and after implementing counseling based on the WOMAN-PRO II program. Results: There were no significant differences between the two groups identified (p = 0.25). Only few aspects were rated highly by all women, such as the overall satisfaction (M = 80.3 %) and satisfaction with organization of care (M = 83.0 %). The evaluation of delivery of health care by APNs in women who received counseling improved significantly (p = 0.031). Conclusions: There are indications, that the practice of both interventions might have improved patient satisfaction and counseling the delivery of health care. The aspects that have been rated low in the PACIC-S11 and G-ACIC indicate possibilities to optimize the delivery of health care.

  8. Vulvar basal cell carcinoma, a rare location

    Full Text Available Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.

  9. A Clinical Approach to Vulvar Ulcers.

    This article discusses the differential diagnosis of vulvar ulcers and describes a general clinical approach to this common but nonspecific examination finding. The differential diagnosis includes sexually and nonsexually transmitted infections, dermatitides, trauma, neoplasms, hormonally induced ulcers, and drug reactions. Patient history and physical examination provide important clues to the cause of a vulvar ulcer. However, laboratory testing is usually required for accurate diagnosis because the clinical presentation is often nonspecific and may be atypical due to secondary conditions.

    1995-01-01

    Purpose: Controversies exist regarding the use of radiation therapy in the treatment of vulvar carcinoma. A retrospective review was performed to evaluate our institution's experience with surgery and radiation for this disease. Methods and Materials: The medical records of 47 patients treated for squamous cell carcinoma of the vulva at our institution (1974-1992) were reviewed for TNM stage (AJCC criteria), treatment modality, and associated 5-year local control and survival based on Kaplan-Meier analysis. Results: Twenty-eight patients (60%) presented with Stage I and II disease and their 5-year survival was 69%. Stage III patients accounted for 12 (25%) of the patients and their 5-year survival was 73%. Seven patients presented with Stage IV disease and five died within 13 months of diagnosis after predominantly palliative therapy. The 40 patients with Stages I, II, and III disease were treated aggressively and were further evaluated for treatment-modality-associated survival and local control. Radiation therapy was used as primary treatment in nine patients, of whom seven were treated with radiation alone and two were treated postoperatively after wide excision. Surgery alone was performed in 31 patients consisting of either radical vulvectomy (20 patients) or wide excision (11 patients). When comparing outcomes of radical vulvectomy vs. radiation therapy, we noted that the 5-year actuarial survivals were comparable (74% for either modality), despite the presence of more favorable prognostic factors in the group treated with radical vulvectomy. Patients treated with wide excision alone had a trend for a poorer 5-year actuarial survival (51%) and local control (50%). Conclusions: Radical vulvectomy offers good locoregional control and survival. This retrospective review further supports the use of radiation therapy with conservative surgery as an alternative treatment option for patients with vulvar carcinoma treated with curative intent. In contrast, the use of

    Objective: To validate a combined technique in the detection of sentinel nodes in early cervix and vulvar cancer patients. Material and Methods: Seventy patients, 24 to 63 years old (average 40 years), with cervical cancer stages IA2, IB1 and IIA, and fourteen patients, 28 to 80 years old (median 68 years) with vulval neoplasm, stage I and II, had sentinel node (SN) detection using lymphoscintigraphy and a gamma probe in the surgical room, after injection of Tc 99m dextran and patent blue dye. Sentinel nodes were seen between 20 and 135 minutes after injection, in cervical cancer, and between one and sixty minutes in vulvar neoplasms. In patients with cervical tumors, 99 sentinel nodes were localized in the obturator region, 28 were interiliac, nine were located in the external iliac region, three in the common iliac region and one was found in perineum. In patients with a vulvar neoplasm, all sentinel nodes were located in the superficial inguinal region. The detection rate was 98,8% for cervical cancer and 100% for vulvar neoplasms, with bilateral drainage in 46% and 29% respectively. Metastases were found in 10,4% (7/65) of IB1 stage cervical cancer patients (6 squamous cell carcinomas - non keratinizing: 5, keratinizing: 1 and one adenocarcionoma) and none in four patients with IA2 stage (with non keratinizing squamous cell carcinoma). The patients with IIA stage cervical cancer (keratinizing squamous cell carcinoma) had metastases in the SN. Three out of 14 patients with vulvar cancer showed metastases in the sentinel node. Two of them had epidermoid carcinoma and one, malignant melanoma. There were no metastases in non-sentinel nodes when sentinel nodes were negative for metastases, both in cervical or vulvar cancer. Conclusion: It is feasible to localize sentinel nodes in cervical and vulvar cancer, using a combined technique with Tc 99m Dextran and 'patent blue'. (author)

    Vulvar cancer has been staged by the International Federation of Gynaecology and Obstetrics (FIGO) since 1969, and the original staging system was based on clinical findings only. This system provided a very good spread of prognostic groupings. Because vulvar cancer is virtually always treated surgically, the status of the lymph nodes is the most important prognostic factor and this can only be determined with certainty by histological examination of resected lymph nodes, FIGO introduced a surgical staging system in 1988. This was modified in 1994 to include a category of microinvasive vulvar cancer (stage IA), because such patients have virtually no risk of lymph node metastases. This system did not give a reasonably even spread of prognostic groupings. In addition, patients with stage III disease were shown to be a heterogeneous group prognostically, and the number of positive nodes and the morphology of those nodes were not taken into account. A new surgical staging system for vulvar cancer was introduced by FIGO in 2009. Initial retrospective analyses have suggested that this new staging system has overcome the major deficiencies in the 1994 system. Crown Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available Background: Malignant vulvar lesions arise from premalignant vulvar intraepithelial neoplasm (VIN and occur only rarely (3–4 % of all malignancies of the female genital organs, especially in the menopause. They are associated with human papillomavirus infection. If the change is found sufficiently early and if it is properly treated, the prognosis is favourable. Methods and patients: We present a case of a 60-year-old multiparous postmenopausal woman with recurrence of the vulvar cancer. In May 1995 vulvar biopsy revealed VIN III. In February 2006 she was examined at the Oncology Institute because of expansive lesions which covered the entire area of external genitals from clitoris to the anus. On 7th March, 2006 vulvectomy with broad safety margins and right-sided lymphadenectomy were made. Histological di- agnosis revealed a well-differentiated invasive squamous cell carcinoma (FIGO II, grade I; postoperative radiotherapy followed. In February 2007, suspicious lesions reoccurred in the external genital area, the smear was negative. In December 2007 histological diagnosis of recurrent squamous cancer was made. On 7th October, 2008 the patient was admitted to the Department of Gynecology, University Medical Centre, Ljubljana. Abdominal computed tomography showed a widespread vulvar cancer, T4 in appearance, suspicious lymph nodes in the pre-sacral area and suspicious left inguinal lymph node. Metastases to the liver were not confirmed. On 28th October, 2008 total Brunschwig operation was performed (pelvic exenteration of the bladder, uterus, pelvic lymph nodes, rectum and radical vulvectomy with resection of both ramus ossis pubis, anus praeter and transposition of skin-muscle flap (m. rectus abdominis. The interdisciplinary operation, which lasted 9 hours and blood loss was 6 litres, involved gynaecologists, a urologist, a plastic surgeon, and an oncology surgeon.

    Lymph node status is the most important prognostic factor in vulvar malignancy. The aim of this pilot study was to explore the clinical significance of radionuclide lymphoscintigraphy in the management of vulvar neoplasms. Eight patients with squamous cell carcinoma and two patients with malignant melanoma of the vulva were studied with 100 MBq technetium-99m nanocolloid (Sentiscint, OSSKI, Budapest) 1 day before surgery. The location of the sentinel lymph node was checked by a single-head gamma camera-computer system (MB 9200, Mediso, Budapest). Vulvectomy with bilateral inguinofemoral lymphadenectomy was performed in each case. At lymphadenectomy, the sentinel lymph node was separately removed and histologically studied. Three of the ten patients had positive sentinel lymph nodes (micrometastasis). Five months later one of them had local recurrence of the vulvar cancer, and another had inguinal recurrence of the tumour 6 months postoperatively; the third patient was operated on only recently. Our preliminary results are impressive and suggest that lymphoscintigraphy is an easy and reliable method for detection of the sentinel lymph node in vulvar malignancy. (orig.)

    Adenoma, myelolipoma, phaeochromocytoma, metastases, adrenocortical carcinoma, neuroblastoma, and lymphoma account for the majority of adrenal neoplasms that are encountered in clinical practice. A variety of imaging methods are available for evaluating adrenal lesions including ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine techniques such as meta-iodobenzylguanidine (MIBG) scintigraphy and positron-emission tomography (PET). Lipid-sensitive imaging techniques such as unenhanced CT and chemical shift MRI enable detection and characterization of lipid-rich adenomas based on an unenhanced CT attenuation of ≤10 HU and signal loss on opposed-phase compared to in-phase T1-weighted images, respectively. In indeterminate cases, an adrenal CT washout study may differentiate adenomas (both lipid-rich and lipid-poor) from other adrenal neoplasms based on an absolute percentage washout of >60% and/or a relative percentage washout of >40%. This is based on the principle that adenomas show rapid contrast washout while most other adrenal neoplasms including malignant tumours show slow contrast washout instead. 18 F-2-fluoro-2-deoxy-D-glucose–PET ( 18 FDG-PET) imaging may differentiate benign from malignant adrenal neoplasms by demonstrating high tracer uptake in malignant neoplasms based on the increased glucose utilization and metabolic activity found in most of these malignancies. In this review, the multi-modality imaging appearances of adrenal neoplasms are discussed and illustrated. Key imaging findings that facilitate lesion characterization and differentiation are emphasized. Awareness of these imaging findings is essential for improving diagnostic confidence and for reducing misinterpretation errors.

    2017-01-01

    Full Text Available Vulvar lichen sclerosus (VLS is a chronic inflammatory dermatosis characterized by ivory-white plaques or patches with glistening surface commonly affecting the vulva and anus. Common symptoms are irritation, soreness, dyspareunia, dysuria, and urinary or fecal incontinence. Anogenital lichen sclerosus (LS is characterized by porcelain-white atrophic plaques, which may become confluent extending around the vulval and perianal skin in a figure of eight configuration. Thinning and shrinkage of the genital area make coitus, urination, and defecation painful. LS is not uncommon in India and present as an itchy vulvar dermatosis which a gynecologist may mistake for candidal vulvovaginitis. There is often a delay in diagnosis of VLS due to its asymptomatic nature and lack of awareness in patients as well as physicians. Embarrassment of patients due to private nature of the disease and failure to examine the genital skin properly are the other reasons for delay in diagnosis. There is no curative treatment for LS. Various medications available only relieve the symptoms. Chronic nature of the disease affects the quality of life. Proper and regular follow-up is required as there are chances of the development of squamous cell carcinoma.

    AIMS: To objectively assess the psychological and psychosexual morbidity of patients with vulvar vestibulitis. METHODS: 30 patients with variable degrees of vulvar vestibulitis were recruited from a vulval clinic. Each patient underwent a detailed history and clinical examination. Friedrich's criteria were used for the diagnosis of vulvar vestibulitis. Standardised questionnaires to assess psychological and psychosexual function were completed by the patient before review. These questionnaires were the STAI and a modified psychosexual questionnaire introduced by Campion. RESULTS: Patients experienced considerable psychological dysfunction compared with controls. All aspects of psychosexual dysfunction were affected. CONCLUSIONS: When managing patients, psychosexual and psychological issues must be considered in addition to other conventional types of therapy. Vulvar vestibulitis may be a risk factor for developing psychosexual complications including vaginismus, low libido, and orgasmic dysfunction. Consideration of these factors must be an integral part of the management of patients with all chronic vulval conditions. PMID:9582478

    Full Text Available Endometriosis is an ectopic occurrence of tissue morphologically and functionally resembling endometrial tissue outside the uterine cavity. Vulva is one of the rarest location of extrapelvic endometriozis. We report a case of a 44-year-old multiparous woman, referred to our clinic with the complaints of having a vulvar mass and cyclic swelling of the mass during menstruation. She had a history of 2 previous cesarean delivery and no history of previous vulvar or vaginal surgery. The mass was 3-4cm in diameter and localized on the upper-portion of the right labium minus. Complete surgical excision was performed with the suspicion of endometriosis. Final histopathology report confirmed the diagnosis of endometriosis. Three weeks after surgery there was no evidence of endometriosis. In conclusion whether or not having a history of a previous vulvar surgery, vulvar endometriosis should be considered as a part of differential diagnosis in evaluation of vulvar masses.

    Merkel cell carcinoma is a rare and aggressive neoplasm originating from mechanoreceptor Merkel cells of the stratum basale of the epidermis. Cases affecting the vulva are exceedingly rare, with the currently available literature primarily in case report form. Systematic review of the PubMed database returned 17 cases of Merkel cell carcinoma affecting the vulva. Patients presented at a mean age of 59.6 years with a firm, mobile vulvar mass. Symptoms of pain, erythema, pruritus, edema, and ulceration have been reported. Tumor histology is consistent with that of neuroendocrine tumors and typical Merkel cell carcinomas. Neuroendocrine and cytokeratin immunostains are frequently utilized in histopathological workup. Surgical management was the unanimous first-line therapy with adjuvant radiation in most cases. Recurrence occurred in 70.6% of patients at a mean follow-up of 6.3 months. Mortality was at 47.0% at a mean of 7.8 months after initial operation. Merkel cell carcinoma affecting the vulva is an extremely rare and highly aggressive neoplasm. The present review of published cases serves to comprehensively describe the clinical course and treatment approaches for vulvar Merkel cell carcinoma.

    2010-10-01

    Current local treatment of vulvar cancer is wide tumor excision and radical vulvectomy based on functional anatomy established from the adult and on the view of radial progressive tumor permeation. Standard surgery is associated with a considerable local failure rate and severe disturbance of the patients' body image. Vulvar field resection (VFR) is based on ontogenetic anatomy and on the concept of local tumor spread within permissive compartments. VFR combined with anatomical reconstruction (AR) is proposed as a new surgical approach to the treatment of vulvar cancer. A prospective trial was launched to test the compartment theory for vulvar cancer and to assess safety and effectiveness of the new therapy. In 54 consecutive patients 46 tumors were locally confined to the tissue compartment differentiated from the vulvar anlage. The 8 tumors having transgressed into adjacent tissue compartments of different embryonic origins exhibited signs of advanced malignant progression. 38 patients with vulvar cancer, stages T1-3 were treated with VFR and AR. The perioperative complication rate was low. At 19 (3-50) months follow-up no patient failed locally. 33 patients estimated their body image as undisturbed. Vulvar cancer permeates within ontogenetic tissue compartments and surgical treatment with VFR and AR appears to be safe and effective. Patients should benefit from the new approach as local tumor control is high and the preserved tissue can be successfully used for restoration of vulvar form and function. Confirmatory trials with more patients and longer follow-up are suggested. Copyright © 2010 Elsevier Inc. All rights reserved.

    INTRODUCTION: Vulvar cancer is a rather common neoplasm in elderly patients. Surgery, followed eventually by postoperative radiotherapy, is the treatment of choice. The results of exclusive radiotherapy (external beam irradiation and/or brachytherapy) are not well defined and in the recent literature only small series are reported. Radiotherapy however is the only therapeutic option in patients who are not fit for radical surgery. It is thus necessary to review its indications and its modalities. PATIENTS METHODS AND RESULTS: From 1990 to 1994 18 pts with a diagnosis of squamous cell carcinoma of the vulva have been submitted to brachytherapy. Age ranged from 60 to 92 years (mean age 76, 1 ys). 14 pts were treated at diagnosis (11 pts) or for recurrent disease after surgery (3 pts). In 8 of them brachytherapy (total dose 35-45 Gy, dose rate: 0,4-0,78 Gy/h) was preceded by external beam irradiation (Co60 or electron beam, 40-50 Gy to primary and inguinal nodes); 6 pts were treated with brachytherapy alone (58-60 Gy; dose rate 0,44-0,63 Gy/h). 4 pts underwent to brachytherapy alone for local recurrence after surgery and postoperative radiotherapy (total dose 45-60 Gy; dose rate 0,37-0,49 Gy/h). Brachytherapy was always performed with 192 Ir. Plastic tubes (2 to 5 lines) were used for single plane implantation of small exophytic lesions limited to the labia (8 cases); a perineal template (10 cases) was employed in lesions extended to the vaginal mucosa or involving the clitoris or the area of the perineum. (10(14)) pts treated at diagnosis are alive and free from local recurrence after 11-48 mos. 3 of them, treated with brachytherapy alone, have presented a nodal recurrence in the groin after 14, 15 and 27 mos. respectively. All of them are alive and free from disease after surgery and external radiotherapy. None of the pts treated for recurrent disease after surgery + external beam radiotherapy has achieved a local control. CONCLUSION: Brachytherapy alone or

It affects elderly females, with the mean age at diagnosis being 55–60 years. Regional metastasis to inguinal lymph nodes is common. There is a high incidence of pelvic node involvement, especially in those with pathologically positive inguinal nodes. Surgery appears to be the only curative treatment option in the early stages of the disease. But in most patients, surgery is associated with considerable morbidities and psychosexual issues. Hence, in the quest for a less morbid form of treatment, multimodality approaches with various combinations of surgery, chemotherapy, and radiation therapy have been suggested for advanced vulvar cancers. Due to the low incidence of the disease, the level of evidence for the success of these treatment modalities is poor. In countries like India, a heterogeneous incidence of vulvar carcinoma exists across the country, with patients presenting at advanced stages when the option of surgery is often supplemented or replaced by chemotherapy and radiotherapy. In this review, we attempt to study the available published literature and trials and discuss the treatment options in various stages of vulvar carcinoma.

    Perineal defects are encountered ever more frequently, in the treatment of vulvar cancers or abdominoperineal resection. The surgical treatment of vulvar cancer leads to significant skin defect. The aim of the reconstruction is not to provide volume but rather to resurface perineum. We propose a new solution to cover the extensive skin defect remaining after excision. We report 3 patients who underwent large excision for vulvar cancer, with lymph node dissection. For reconstruction, we performed 3 advancement flaps. Two V-Y flaps cantered on the infra-gluteal folds and based on pudendal perforator arteries were used to cover the postero-lateral parts of the defect. The third advancement flap from the superior aspect of the defect was a Y-V Mons pubis flap. The defects were successfully covered by the 3 flap technique. The first patient suffered a non-union that slowly healed by secondary intention. For the other cases, we used the same technique, but applied negative pressure wound therapy on the sutures, with excellent results. The 3 flap technique is a simple and reliable method and the donor site morbidity is minimal. It can be realised without changing the position of the patient after tumour excision, and does not require delicate perforator dissection. This surgical option can be easily applied, allowing better management of these cases. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    We examined stereotyping of chronic pain sufferers among women aged 18-40 years and determined whether perceived stereotyping affects seeking care for women with chronic vulvar pain. Cross-sectional study using a community-based survey of vulvodynia asking if "Doctors think that people with chronic pain exaggerate their pain," and if "People believe that vulvar pain is used as an excuse to avoid having sex". Twelve thousand eight hundred thirty-four women aged 18-40 years in metropolitan Minneapolis/St. Paul, Minnesota. Women were considered to have a history of chronic vulvar pain if they reported vulvar burning lasting more than 3 months or vulvar pain on contact. Four thousand nine hundred eighty-seven (38.9%) women reported a chronic pain condition; 1,651 had chronic vulvar pain. Women experiencing chronic pain were more likely than those without to perceive stereotyping from both doctors and others; a dose-response with the number of pain conditions existed. Women with chronic vulvar pain were more likely to believe that people think vulvar pain is an excuse to avoid intercourse. Half of the women with chronic vulvar pain did not seek medical care for it; of these, 40.4% perceived stereotyping from doctors. However, it was women who actually sought care (45.1%) who were more likely to feel stigmatized by doctors (adjusted relative risk = 1.11, 95% confidence interval: 1.01-1.23). Perceived negative stereotyping among chronic pain sufferers is common, particularly negative perceptions about physicians. In fact, chronic vulvar pain sufferers who felt stigmatized were more likely to have sought care than those who did not feel stigmatized. Wiley Periodicals, Inc.

The objective of the present report is to describe a case of vulvar myiasis due to larvae of Cochliomyia hominivorax. A 77-year-old woman with precarious hygienic habits presented pain, pruritus and secretions with a fetid smell in the genital region for 10 days. Gynecological examination demonstrated an ulcerated lesion in the labium majus of the vulva measuring six centimeters that extended to the mons pubis and was found to be filled with larvae. The patient progressed favorably after removal of the larvae, surgical debridement and daily dressings. Fourteen days after the debridement, she was submitted to skin flap rotation, with good local scar formation. Two months after the intervention, she remained asymptomatic. Vulvar myiasis must be considered in the differential diagnosis of infectious diseases of the vulva in patients with precarious hygienic habits.

Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain.

    The carcinogenic role of high-risk human papillomavirus (HR-HPV) types in the increasing subset of vulvar intraepithelial neoplasia and vulvar cancer in young women has been established. However, the actual number of vulvar cancer cases attributed to HPV is still imprecisely defined. In an attempt to provide a more precise definition of HPV-driven vulvar cancer, we performed HPV-type-specific E6*I mRNA analyses available for 20 HR-/possible HR (pHR)-HPV types, on tissue samples from 447 cases of vulvar cancer. HPV DNA genotyping was performed using SPF10-LiPA 25 assay due to its high sensitivity in formalin-fixed paraffin-embedded tissues. Data on p16 INK4a expression was available for comparative analysis via kappa statistics. The use of highly sensitive assays covering the detection of HPV mRNA in a broad spectrum of mucosal HPV types resulted in the detection of viral transcripts in 87% of HPV DNA+ vulvar cancers. Overall concordance between HPV mRNA+ and p16 INK4a upregulation (strong, diffuse immunostaining in >25% of tumor cells) was 92% (K=0.625, 95% confidence interval (CI)=0.531-0.719). Among these cases, 83% were concordant pairs of HPV mRNA+ and p16 INK4a + and 9% were concordant pairs of HPV mRNA- and p16 INK4a -. Our data confirm the biological role of HR-/pHR-HPV types in the great majority of HPV DNA+ vulvar cancers, resulting in an HPV-attributable fraction of at least 21% worldwide. Most HPV DNA+ vulvar cancers were associated with HPV16 (85%), but a causative role for other, less frequently occurring mucosal HPV types (HPV26, 66, 67, 68, 70 and 73) was also confirmed at the mRNA level for the first time. These findings should be taken into consideration for future screening options as HPV-associated vulvar preneoplastic lesions have increased in incidence in younger women and require different treatment than vulvar lesions that develop from rare autoimmune-related mechanisms in older women.

    Full Text Available The objective of this paper is to present general considerations which should be kept in mind by clinicians in charge of women with vulvar diseases. Four representative vulvar dermatoses are described. Lichen simplex chronicus is a pathological condition related to chemical and mechanical irritant agents. Detrimental effects of these irritants, in the presence of other dermatoses, have to be considered when therapeutic responses are unsatisfactory. Lichen sclerosus is the most common vulvar dermatosis in elderly. However, it should be kept in mind that it may be diagnosed at any age. Lichen planus, in spite of sharing a similar range of etiological factors with lichen sclerosus, is a very distinct entity. Finally, Paget’s disease, although rare, is also described especially because of the challenge it represents both clinically and therapeutically.

    When assessing women with chronic vulvar pain, women's health physical therapists search for comorbid mechanical components (including musculoskeletal, fascial, and visceral) and other disorders that may contribute to or be caused by chronic vulvar pain (CVP). Pelvic floor hypertonicity is a key perpetuating factor for CVP. Comprehensive physical therapy evaluation and suggested physical therapy interventions are described. Anatomy of the pelvis, common evaluative findings, and specifics for pelvic floor muscle rehabilitation are presented. Normalization of pelvic floor muscle function contributes to the reduction of CVP. Successful treatment includes the identification and treatment of co-existing physical abnormalities throughout the trunk and pelvis. © 2010 Wiley Periodicals, Inc.

Cellular angiofibroma is generally a small and asymptomatic mass that primarily arises in the vulvar-vaginal region, although rare cases have been reported in the pelvic and extrapelvic regions. It affects women most often during the fifth decade of life. The treatment requires simple local excision due to low local recurrence and no chance of metastasization.

    Massive vulvar edema in a woman with preeclampsia preceded the development of massive ascites and impending eclampsia. A 17-year-old preeclamptic, primiparous woman was admitted with preeclampsia and massive vulvar edema. Other causes were excluded. The vulvar edema increased as the blood pressure and ascites increased, and a severe headache developed. Cesarean section for increasing preclampsia was performed. In the puerperium, the blood pressure improved and vulvar edema resolved. The clinical picture of the vulvar edema correlated with the severity of the preeclampsia. The presence of vulvar edema in women with preeclampsia should indicate immediate admission to the hospital. These patients must be considered as at high risk, and close monitoring must be instituted. In our case, vulvar edema preceded massive ascites development. We assume a common development mechanism for these signs in preeclampsia, due mainly to increased capillary permeability and hypoalbuminemia. The attending physician must be prepared for immediate delivery and possible preeclampsia complications in these patients.

The study is intended to serve as a basis for a general assessment of the incidence of neoplasms in children, and of cancer mortality in the entire population of Bavaria in the years 1983-1989, or 1979-1988, respectively, with the principal idea of drawing up an environment-related health survey.

Therapy: The gold standard for even a small invasive carcinoma of the vulva was historically radical vulvectomy with removal of the tumor with a wide margin followed by an en bloc resection of the inguinal and often the pelvic lymph nodes. Currently, a more individualized and less radical treatment is suggested: a radical wide local excision is possible in the case of localized lesions (T1.

    Vulvar carcinoma is a rare tumor of the female genital tract. In Nigeria, very few studies have looked at the management options for vulvar carcinoma. The objective of this study was therefore, to describe the management options available and the challenges in treating this malignancy in Nigeria. A descriptive study of all vulvar cancer cases managed at the Nnamdi Azikiwe University Teaching Hospital, Nnewi over a 12 year period (1998-2009). The theatre, ward register, histo-pathologic records and case notes of all women who had surgery for vulvar carcinomas were retrieved and socio-demographic characteristics, clinical presentation, type of surgery, histologic type and complications of treatment were retrieved and analyzed. There were 867 gynecological malignancies and vulval carcinoma accounted for 11 cases, giving a prevalence of 1.27%. The ages ranged from 54 to 79 years with a mean of 61.2 years. Parity was 2-14, with a mean of 6.7 ± 2.33. Most of the patients were of low socio-economic class. All the 11 patients had surgery as 1st line treatment. Radical vulvectomy was done for 6 cases since they presented in the advanced stage. The complications of surgery included hemorrhage (18.2%), chronic lymphedema, wound infection and anesthetic complications. There were no hospital mortalities. Late presentation, with stage III (45.4%) was the commonest stage at presentation while the majority of the vulvar carcinomas (72.7%) were of epithelial origin. Squamous cell carcinoma predominated (63.6%). Carcinoma of the vulva is a rare gynecological malignancy in Nigeria. Surgery and radiotherapy remains the mainstay of this disease in Nigeria and can be highly successful if patients present early.

    Full Text Available Background: The management of women with chronic benign vulvar dermatoses has been one of the most difficult and challenging aspects of women′s healthcare for a long time. Aim: Our aim was to compare the ability to approach the specific diagnosis of nonneoplastic and noninfectious vulva diseases, between the new classification system and the old classification system. Methods: One hundred women with chronic vulvar pruritus were included in the study. After detailed examination of the vulva, all visible lesions were biopsied, with normal skin included. All specimens was sent for dermatopathology and examined simultaneously under a binocular microscope by two pathologists. Specific diagnosis if possible and histopathological findings were classified according to both the 1987 and 2006 International Society for the Study of Vulvar Diseases (ISSVD classifications. The ratios that were able to be approached on the specific diagnosis, with the aid the two classification systems, were compared. Results: Specific clinical diagnosis by both pathological and after using clinicopathological correlation was possible in 69 out of 91 patients (75.8% according to the 1987 ISSVD classification, and in 81 out of 91 patients (89.0% according to the ISSVD 2006 classification system. The difference in the clinical diagnosis ratios between the two classification systems was statistically significant ( P < 0.05. In a subgroup of women without specific diagnosis at the time of pathological examination, clinical diagnosis was made in 28 out of 50 women (56% after using the clinicopathological correlation according to the ISSVD 1987 classification, whereas, specific diagnosis was made in 39 out of 49 (79.6% women after using the clinicopathological correlation according to the ISSVD 2006 classification. The difference was statistically significant in terms of the ratio of the ability to achieve a specific diagnosis ( P < 0.01. Conclusion: ISSVD 2006 classification of

    Vulvovaginitis, labial adhesions, and other vulvar disorders occur commonly in children and can provoke high anxiety in both the parent and child. Performed correctly, the pediatric gynecologic examination can diagnose and treat, educate and reassure both parent and child. This examination requires patience, sensitivity, direct communication with the child as well as with the parent, and an open manner that inspires trust in both parties to manage a potentially anxiety-provoking situation. This chapter will review common vulvar disorders, including vulvovaginitis, lichen sclerosis et atrophicus, bubble bath vaginitis, labial adhesions, urethral prolapse, and other common problems. A discussion of childhood sexual abuse is beyond the scope of this chapter, with appropriate references available elsewhere. Practical pearls will be offered to make this exam easy for the primary care clinician and/or subspecialist. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available Objectives. Vulvar cancer is a rare gynecological malignancy, with an incidence of 1.5 per 100 000 women/year. The most common vulvar cancer is developed in squamous cells, the most encountered type of skin cells. Case report. We report a case of a 72-year-old female admitted in the Department of Plastic Surgery of Emergency Clinical Hospital “Prof. Dr. Agrippa Ionescu” with a 5/4.2 cm painful ulcerated tumoral mass located in the vulvar area. The lesion slowly increased in size over the past 12 months. The tumour was surgically removed with oncological safety margins and sent for histopathological evaluation. The histopathological examination revealed an ulcerated squamous carcinoma with lymphovascular and perineural invasion, but with negative margins. Postoperative results were favorable, and no local or general complications were observed. Conclusion. We highlight this case due to its unusual presentation in the clitoral area. Moreover, considering the potential for recurrence we point out the importance of the radical vulvectomy with regional lymphadenectomy and histopathological examination, in order to put a precise diagnosis and ensure the best possible treatment for the patient.

    Twenty-four women with suspected gestational trophoblastic neoplasms were evaluated prospectively to identify imaging algorithms optimal for treatment planning. All underwent chest radiography, chest CT, hepatic and cranial CT or MR imaging, and pelvic MR imaging. Ten also underwent pelvic CT, 13 pelvic US. The most sensitive imaging combination was chest CT, hepatic and cranial CT or MR imaging, and pelvic MR imaging. However, correct assignment to ACOG therapeutic categories was achieved by means of history, physical examination, beta subunit of human chorionic gonadotropin measurements, and chest radiography in 81% of patients. Hepatic and cranial imaging defined the need for radiation therapy. Chest CT was needed only when chest radiographs were negative. Pelvic imaging aided diagnosis but did not assist in treatment planning

    Full Text Available Context. Vulvar pain level may fluctuate in women with vulvodynia even in the absence of therapy; however, there is little evidence suggesting which factors may be associated with variability. Objective. Determine the feasibility of using smartphones to collect prospective data on vulvar pain and factors that may influence vulvar pain level. Methods. 24 clinically confirmed women were enrolled from a population-based study and asked to answer five questions using their smartphones each week for one month. Questions assessed vulvar pain level (0–10, presence of pain upon wakening, pain elsewhere in their body, treatment use, and intercourse. Results. Women completed 100% of their scheduled surveys, with acceptability measures highly endorsed. Vulvar pain ratings had a standard deviation within women of 1.6, with greater variation on average among those with higher average pain levels (P<0.001. On the weeks when a woman reported waking with pain, her vulvar pain level was higher by 1.82 on average (P<0.001. Overall, average vulvar pain level was not significantly associated with the frequency of reporting other body pains (P=0.64. Conclusion. Our smartphone tracking system promoted excellent compliance with weekly tracking of factors that are otherwise difficult to recall, some of which were highly associated with vulvar pain level.

    There are 2 types of vulvar intraepithelial neoplasia (VIN): warty-basaloid and differentiated. Differentiated VIN is uncommon and seldom diagnosed prior to carcinoma and, traditionally, is not graded. There are currently 3 grading systems for warty-basaloid VIN: the World Health Organization (WHO) 3 grade system of VIN 1-3, a 2 grade system of low and high grade vulvar intraepithelial lesions, and the revised International Society for the Study of Vulvovaginal Disease (ISSVD) classification which has no grading of VIN. According to the ISSVD, VIN 1 should be abolished and VIN 2 and 3 combined into a single category, simply termed warty-basaloid VIN. To determine the best system for grading warty-basaloid VIN and learn more about differentiated VIN, we reviewed the pathology of 164 consecutive women with VIN. Of these, 134 (82.3%) had warty-basaloid VIN, 29 (18.2%) had differentiated VIN, and 1 had both. Of warty-basaloid VIN cases, 4 had VIN 1, 13 VIN 2, and 118 VIN 3 when graded according to the WHO. All VIN 1 occurred in condylomata acuminata. VIN 2 and 3 were distinguished only by degree of abnormality. Differentiated VIN was diagnosed before SCC in only 7 cases (26.7%). Because the only VIN 1 cases seen were in condylomata acuminata and because VIN 2 and 3 were difficult to distinguish and there appears little clinical reason to do so, our study supports the ISSVD proposal that VIN 1 be abolished and VIN 2 and 3 be combined. There needs to be more clinical awareness of vulvar conditions, so that differentiated VIN is biopsied before cancer has supervened.

    Mead, Adam J; Mullally, Ann

    2017-03-23

    Myeloproliferative neoplasms (MPNs) arise in the hematopoietic stem cell (HSC) compartment as a result of the acquisition of somatic mutations in a single HSC that provides a selective advantage to mutant HSC over normal HSC and promotes myeloid differentiation to engender a myeloproliferative phenotype. This population of somatically mutated HSC, which initiates and sustains MPNs, is termed MPN stem cells. In >95% of cases, mutations that drive the development of an MPN phenotype occur in a mutually exclusive manner in 1 of 3 genes: JAK2 , CALR , or MPL The thrombopoietin receptor, MPL, is the key cytokine receptor in MPN development, and these mutations all activate MPL-JAK-STAT signaling in MPN stem cells. Despite common biological features, MPNs display diverse disease phenotypes as a result of both constitutional and acquired factors that influence MPN stem cells, and likely also as a result of heterogeneity in the HSC in which MPN-initiating mutations arise. As the MPN clone expands, it exerts cell-extrinsic effects on components of the bone marrow niche that can favor the survival and expansion of MPN stem cells over normal HSC, further sustaining and driving malignant hematopoiesis. Although developed as targeted therapies for MPNs, current JAK2 inhibitors do not preferentially target MPN stem cells, and as a result, rarely induce molecular remissions in MPN patients. As the understanding of the molecular mechanisms underlying the clonal dominance of MPN stem cells advances, this will help facilitate the development of therapies that preferentially target MPN stem cells over normal HSC. © 2017 by The American Society of Hematology.

    The aim of the study was to estimate the risk of high-grade cervical and vaginal intraepithelial neoplasia (CIN/VAIN 2+) and cancer among women treated surgically for high-grade vulvar intraepithelial neoplasia (HGVIN) and vulvar cancer. We performed a retrospective cohort study of women who underwent surgery for HGVIN/vulvar cancer between 2006 and 2010. Univariate and multivariate analyses using stepwise selection were used to identify correlates of abnormal cytology after treatment for VIN and vulvar cancer. Among 191 women under surveillance for a median of 3.7 years who underwent treatment for HGVIN/vulvar cancer, primary vulvar lesions included VIN 2 (10, 5%), VIN 3 (102, 53%), and carcinoma (79, 41%). During follow-up, 71 (37%) had abnormal cytology, including 47 (25%) low grade, 23 (12%) high grade, and 1 (0.5%) carcinoma. Subsequent risk for VAIN 2+ was 11% (6/57) after previous hysterectomy and 8% for CIN 2+ (10/124) with intact cervix. Overall risk for CIN 3+ was 5%. Correlates of high-grade cytology after treatment for HGVIN/vulvar cancer included nonwhite race (odds ratio [OR] = 3.3, 95% CI = 1.50-7.36), immunodeficiency (OR = 4.2, 95% CI = 1.76-9.94), and previous abnormal cytology (OR = 2.7, 95% CI = 1.29-5.78). Stepwise multivariate analysis revealed immunosuppression as the only significant correlate of high-grade cytology after vulvar treatment (adjusted OR = 3.7, 95% CI = 1.26-10.83). Women with HGVIN/cancer should have cervical/vaginal cytology before vulvar surgery. Those with a negative cervical or vaginal cytology result should undergo cytology testing at 1- to 3-year intervals, based on the threshold for CIN 3+ set forth by the American Society for Colposcopy and Cervical Pathology.

    Human papillomavirus (HPV) infection is in the vast majority of patients accountable for the development of vulvar, cervical and vaginal intraepithelial neoplasia (VIN, CIN, VAIN); precursors of vulvar, cervical and vaginal cancers. The currently preferred treatment modality for high grade VIN, CIN and VAIN is surgical excision. Nevertheless surgical treatment is associated with adverse pregnancy outcomes and recurrence is not uncommon. The aim of this review is to present evidence on the efficacy, safety and tolerability of imiquimod (an immune response modifier) in HPV-related VIN, CIN and VAIN. A search for papers on the use of imiquimod in VIN, CIN and VAIN was performed in the MEDLINE, EMBASE and Cochrane library databases. Data was extracted and reviewed. Twenty-one articles met the inclusion criteria and were analyzed; 16 on VIN, 3 on CIN and 2 on VAIN. Complete response rates in VIN ranged from 5 to 88%. Although minor adverse effects were frequently reported, treatment with imiquimod was well tolerated in most patients. Studies on imiquimod treatment of CIN and VAIN are limited and lack uniformly defined endpoints. The available evidence however, shows encouraging effect. Complete response rates for CIN 2-3 and VAIN 1-3 ranged from 67 to 75% and 57 to 86% respectively. More randomized controlled trials on the use of imiquimod in CIN, VAIN and VIN with extended follow-up are necessary to determine the attributive therapeutic value in these patients.

    The vulvar cancer is the fourth more frequent neoplasia after the endometrial, cervix and ovarian cancer. Normally, it has been related to old women of ages from 70 to 80 years old. Rarely, it has been detected cases in adult or young women. However, its incidence has been increased in the last years and in more early years. It is for this change in the incidence and its appearance in early years why a possible etiology has been looked for, opening different hypothesis that go from that related to the HPV to those that study an inflammatory chronic process as the basis for the carcinogenesis. In this article, it has been presented the case of a woman who is 34 years old with negative VPH that made her debut with epidermoid carcinoma of the vulva moderately different and on purpose of the case, we do a revision of the literature existent. Vulvar cancer diagnosed in young women as in older, but with different trends, risk factors and natural history. The case reported here escapes the theories studied so far so needed new lines of inquiry to investigate this form of presentation young woman, without HPV infection.

    Dendritic cell neoplasms are rare tumors that are being recognized with increasing frequency. They were previously classified as lymphomas, sarcomas, or histiocytic neoplasms. The World Health Organization (WHO) classifies dendritic cell neoplasms into five groups: Langerhans' cell histiocytosis, Langerhans' cell sarcoma, Interdigitating dendritic cell sarcoma/tumor, Follicular dendritic cell sarcoma/tumor, and Dendritic cell sarcoma, not specified otherwise (Jaffe, World Health Organization classification of tumors 2001; 273-289). Recently, Pileri et al. provided a comprehensive immunohistochemical classification of histiocytic and dendritic cell tumors (Pileri et al., Histopathology 2002;59:161-167). In this article, a concise overview regarding the pathological, clinical, and therapeutic aspects of follicular dendritic, interdigitating dendritic, and Langerhans' cell tumors is presented.

    Background: irradiation has established itself as a treatment for vulvar and vaginal malignancies. Due to the sensitive nature of the vulvar and vaginal tissues, interstitial brachytherapy (iBT) provides an effective, gentle and individualized therapy. Patients and Methods: patients with vulvar (nine of 22) and vaginal (13 of 22) malignancies were treated using interstitial pulsed-dose-rate brachytherapy (PDR-iBT). Twelve out of 22 patients were additionally treated using external-beam therapy to the pelvis and regional lymph nodes. The median total dose of PDR-iBT administered to patients with vulvar carcinoma was 55.0 Gy. The median total PDR dose administered to patients with vaginal malignancies amounted to 20.25 Gy. Results: the median follow-up time for patients with vulvar cancer was 19 months and for patients with vaginal malignancies 27 months. Acute mucositis or skin reactions during iBT were observed in 15 of 22 patients. Two of 22 patients showed delayed side effects. After 6 months, 77.8% of the patients with vulvar cancer (seven out of nine) and 100% of the patients with vaginal malignancies (13 out of 13) achieved complete local remission. One patient out of nine with vulvar carcinoma developed local recurrence, four out of nine regional recurrence, and two out of nine developed regional recurrence and had local tumor following therapy. In patients with malignancies of the vagina, no cases of local recurrence were observed, but distant metastases were found in five out of 13 patients. At the time of analysis, eleven out of 22 patients with vulvar or vaginal carcinoma were still alive. Conclusion: IBT achieved good local control without serious delayed side effects in both localizations. However, survival is limited by regional or distant metastases. (orig.)

    Purpose: Local recurrence is a significant problem following primary surgery for advanced vulva carcinoma. The objectives of this study were to evaluate the impact of adjuvant vulvar radiation on local control in high risk patients and the impact of local recurrence on overall survival. Methods and Materials: From 1980-1994, 62 patients with invasive vulva carcinoma and either positive or close (less 8 mm) margins of excision were retrospectively studied. Thirty-one patients were treated with adjuvant radiation therapy to the vulva and 31 patients were observed after surgery. Kaplan-Meier estimates and the Cox proportional hazard regression model were used to evaluate the effect of adjuvant radiation therapy on local recurrence and overall survival. Independent prognostic factors for local recurrence and survival were also assessed. Results: Local recurrence occurred in 58% of observed patients and 16% in patients treated with adjuvant radiation therapy. Adjuvant radiation therapy significantly reduced local recurrence rates in both the close margin and positive margin groups (p = 0.036, p = 0.0048). On both univariate and multivariate analysis adjuvant radiation and margins of excision were significant prognostic predictors for local control. Significant determinants of actuarial survival included International Federation of Gynecologists and Obstetricians (FIGO) stage, percentage of pathologically positive inguinal nodes and margins of excision. The positive margin observed group had a significantly poorer actuarial 5 year survival than the other groups (p = 0.0016) and adjuvant radiation significantly improved survival for this group. The 2 year actuarial survival after developing local recurrence was 25%. Local recurrence was a significant predictor for death from vulva carcinoma (risk ratio 3.54). Conclusion: Local recurrence is a common occurrence in high risk patients. In this study adjuvant radiation therapy significantly reduced local recurrence rates and

    Purpose: The purpose of this study was to develop a radiation therapy (RT) contouring atlas and recommendations for women with postoperative and locally advanced vulvar carcinoma. Methods and Materials: An international committee of 35 expert gynecologic radiation oncologists completed a survey of the treatment of vulvar carcinoma. An initial set of recommendations for contouring was discussed and generated by consensus. Two cases, 1 locally advanced and 1 postoperative, were contoured by 14 physicians. Contours were compared and analyzed using an expectation-maximization algorithm for simultaneous truth and performance level estimation (STAPLE), and a 95% confidence interval contour was developed. The level of agreement among contours was assessed using a kappa statistic. STAPLE contours underwent full committee editing to generate the final atlas consensus contours. Results: Analysis of the 14 contours showed substantial agreement, with kappa statistics of 0.69 and 0.64 for cases 1 and 2, respectively. There was high specificity for both cases (≥99%) and only moderate sensitivity of 71.3% and 64.9% for cases 1 and 2, respectively. Expert review and discussion generated consensus recommendations for contouring target volumes and treatment for postoperative and locally advanced vulvar cancer. Conclusions: These consensus recommendations for contouring and treatment of vulvar cancer identified areas of complexity and controversy. Given the lack of clinical research evidence in vulvar cancer radiation therapy, the committee advocates a conservative and consistent approach using standardized recommendations.

Results: Analysis of the 14 contours showed substantial agreement, with kappa statistics of 0.69 and 0.64 for cases 1 and 2, respectively. There was high specificity for both cases (≥99%) and only moderate sensitivity of 71.3% and 64.9% for cases 1 and 2, respectively. Expert review and discussion generated consensus recommendations for contouring target volumes and treatment for postoperative and locally advanced vulvar cancer. Conclusions: These consensus recommendations for contouring and treatment of vulvar cancer identified areas of complexity and controversy. Given the lack of clinical research evidence in vulvar cancer radiation therapy, the committee advocates a conservative and consistent approach using standardized recommendations.

    Full Text Available About 100 million women are estimated to be circumcised globally. Various rates of complications have been encountered, especially after circumcision, such as bleeding, infection, shock, menstrual irregularity, difficulty in urination or common urinary tract infections, inguinal pain, difficulty in sexual intercourse, and genital circumcision scar especially at the vulvar region, and cystic or solid character mass in short and long term. Furthermore, the maternal-fetal morbidity and mortality increase due to bleeding and fistula, which develop after prolonged labor, travail, and difficult labors. Our aim in this paper was to discuss a 42-year-old multiparous female case who had undergone type 2 radical genital mutilation (circumcision when she was 7 years of age, along with the literature, which has been evaluated for the gradually growing mass at the left inguinal canal region in the last 10 years and diagnosed as epidermoid inclusion cyst developing secondary to postcircumcision surgical ground trauma, since there was no other case found in the literature search that had been circumcised at such an early age and developing after circumcision at such advanced age, and, therefore, this is suggested to be the first case on this subject.

    Full Text Available Colonic type villoglandular adenocarcinoma of the lower genital tract is an extremely rare condition. Its origin is not clearly understood; however, the cloacal remnants are the more accepted source for this carcinoma.We report the case of a 67-year-old female patient who presented with a 1.2 cm polypoidal nodule at the right side of the fourchette. Morphologic studies revealed a colonic type mucinous adenocarcinoma that arose from within a villous adenoma. Immunohistochemical staining showed positive cytokeratin 7, cytokeratin 20, carcinoembryonic antigen, P53, and progesterone receptor, but negative for estrogen receptor and caudal type homeobox transcription factor 2. Extensive work-up failed to reveal other primary cancers in this patient. Ultimately, she underwent a radical vulvectomy. No recurrence was seen in eight months follow up of this patient after surgery. Careful, thorough histological evaluation and clinical clues enable correct diagnosis of the rare colonic type vulvar villoglandular adenocarcinoma. Due to rarity of this tumor, its management is questionable. Therefore, additional investigation is necessary for its management.

    Full Text Available Actinomycosis is a chronic infection caused by Actinomyces israelii, usually seen in immunocompromised patients or in the background of tissue injury. Vulvar actinomycosis presenting as a fixed swelling in an elderly individual can mimic malignancy and pose a diagnostic dilemma. We report here a case of vulvar actinomycosis diagnosed by fine needle aspiration (FNA. A 60-year-old postmenopausal female presented with a gradually increasing 15 cm × 10 cm vulvar swelling involving the right mons and right labia majora. The swelling was nodular, fixed, and nonulcerated, with multiple healed and few active discharging sinus tracts draining serosanguineous fluid and yellowish sulfur granules. FNA was diagnostic, as it revealed colonies of Actinomyces surrounded by polymorphs. Histopathology of excised specimen confirmed the cytological findings. FNA is an effective tool in the diagnosis of actinomycosis, although, its documentation is rare. Difficulties in the management can be avoided by early diagnosis using the FNA technique.

    Surgery is the only treatment that may cure the patient with gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) and should always be considered as the first-line treatment if radical resection can be achieved. Even in cases where radical surgery is not possible, palliative resection may...... be performed to reduce local or hormone-induced symptoms and to improve quality of life. The surgical procedures for GEP-NENs are accordingly described below. In most patients life-long follow-up is required, even following radical surgery, as recurrence may occur several years later....

    A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical and ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings

    Mammary glands located in the vulvar region have been named as ectopic breast tissue or anogenital mammary glands by different authors. Literature on pathologies of ectopic breast tissue located in the vulvar region is rare. Most of the reports are about the malignancies arising from this ectopic tissue. We report a case of fibrocystic disease of the mammary glands in the vulva in a 25-year-old pregnant woman. Her disease was exaggerated during pregnancy. Ectopic breast tissue in the vulva is a rare entity and fibrocystic disease of this tissue has rarely been reported in the English literature. Copyright (c) 2004 S. Karger AG, Basel.

    Lichen sclerosus (LS) is a chronic inflammatory condition that is known to arise on the vulva. Many women with LS report vulvar pain, often affecting a patient's quality of life. In this study, the sexual function of LS patients, with and without pain, was compared to control populations. A case-control study to examine the relationship between LS and sexual dysfunction was conducted. A total of 335 women presenting to the gynecology clinic were included in the study: 197 women with biopsy confirmed LS were compared to two control groups (95 asymptomatic women were "healthy" controls and 43 women had vulvovaginal candidiasis) on self-reported current health complaints, medical and surgical history and current symptoms such as pain and itching, type and frequency of sexual activity, and satisfaction with sexual activity. Women with LS reported less frequent sexual activity than healthy controls (p=0.007) and Candida controls (p=0.04). Currently sexually active women with LS were significantly less likely to report vaginal intercourse (71.6%) than healthy controls (89.0%, p=0.003) or Candida controls (100%, p=0.0003), even though similar proportions of all three groups reported that vaginal intercourse was important. Satisfaction towards the quality of current sexual activity was significantly lower among women with LS compared with both the healthy and Candida control groups. 23.7% of women with LS reported that sexual activity was rarely or never satisfactory as compared with 0% of healthy controls (psexual activity and less satisfying sexual activity when compared with controls.

    The sentinel node is the first lymph node that receives the lymph drainage from the primary tumour. The pathological status of the sentinel node should reflect the histopathology of the entire regional lymph drainage area - both vulvar and cervical cancer spread through the lymphatic system. In gynaecological oncology recent studies have confirmed the utility of the sentinel node concept in vulvar and cervical cancer. Three techniques for sentinel node localisation are available. The preoperative lymphoscintigraphy and intraoperative handheld gamma probe detection require the administration of the technetium-99m-labelled colloid around the tumour. The other method is based on the injection of the patent blue dye - during the surgery of the sentinel node because of the dye uptake becomes visible. Following detection, the sentinel lymph node can be removed separately and assessed with ultrastaging and immunohistochemical staining. In the early stages of vulvar and cervical cancer the lymph nodes metastases rate is relatively low - in most cases lymphadenectomy is not necessary. The determination of the regional lymph nodes' pathological status may limit the extent of the surgical treatment. The sentinel node detection rate is relatively high and depends on the applied technique. This technique may play an important role in the treatment of vulvar and cervical cancer. This paper describes the details of sentinel node identification and reviews the literature. (author)

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

    Traditional means of detecting CNS neoplasms include plain film studies, isotope brain scans, angiography, pneumoencephalography, and myelography. Computed tomography (CT) scanning has replaced nearly all of these studies in both the initial detection and follow-up of brain tumors. Air studies (pneumoencephalography and ventriculography) have been virtually eliminated, except in certain unusual circumstances when two positions need to be checked, or hydrocephalus followed. The nuclear brain scan has a very limited role at present, being useful primarily for detecting skull or meningeal metastases. Myelography, however, remains a valuable imaging tool for the assessment of tumors of the spinal canal. CT scanning has not only improved our ability to detect smaller brain tumors, but also CT guided stereotactic biopsy techniques provide a safer means of obtaining tissue from these smaller lesions, regardless of location. Surgical techniques, guided by CT sterotactic techniques, show promise as well, but the impact of these therapeutic techniques on survival statistics remains to be defined. CT has revolutionized the approach to the detection and diagnosis of space-occupying lesions in the brain. Tumors can be detected at a smaller site

    Since the discovery of the JAK2 V617F mutation in the majority of the myeloproliferative neoplasms (MPN) of polycythemia vera, essential thrombocythemia and primary myelofibrosis ten years ago, further MPN-specific mutational events, notably in JAK2 exon 12, MPL exon 10 and CALR exon 9 have been identified. These discoveries have been rapidly incorporated into evolving molecular diagnostic algorithms. Whilst many of these mutations appear to have prognostic implications, establishing MPN diagnosis is of immediate clinical importance with selection, implementation and the continual evaluation of the appropriate laboratory methodology to achieve this diagnosis similarly vital. The advantages and limitations of these approaches in identifying and quantitating the common MPN-associated mutations are considered herein with particular regard to their clinical utility. The evolution of molecular diagnostic applications and platforms has occurred in parallel with the discovery of MPN-associated mutations, and it therefore appears likely that emerging technologies such as next-generation sequencing and digital PCR will in the future play an increasing role in the molecular diagnosis of MPN. © 2015 John Wiley & Sons A/S.

    2015-01-01

    Full Text Available The relationship between renal damage and malignant neoplasms is one of the most actual problems of the medicine of internal diseases. Very often, exactly availability of renal damage determines the forecast of cancer patients. The range of renal pathologies associated with tumors is unusually wide: from the mechanical effect of the tumor or metastases on the kidneys and/or the urinary tract and paraneoplastic manifestations in the form of nephritis or amyloidosis to nephropathies induced with drugs or tumor lysis, etc. Thrombotic complications that develop as a result of exposure to tumor effects, side effects of certain drugs or irradiation also play an important role in the development of the kidney damage. The most frequent variants of renal damage observed in the practice of medical internists (therapists, urologists, surgeons, etc., as well as methods of diagnosis and treatment approaches are described in the article. Timely and successful prevention and treatment of tumor-associated nephropathies give hope for retaining renal functions, therefore, a higher life standard after completion of anti-tumor therapy. Even a shortterm episode of acute renal damage suffered by a cancer patient must be accompanied with relevant examination and treatment. In the caseof transformation of acute renal damage into the chronic kidney disease, such patients need systematic and weighted renoprotective therapy and correct dosing of nephrotoxic drugs.

  5. Metastatic neoplasms of the central nervous system

    Fenner, W.R.

    1990-01-01

    Metastatic neoplasms to the central nervous system are often encountered in the practice of surgical neuropathology. It is not uncommon for patients with systemic malignancies to present to medical attention because of symptoms from a brain metastasis and for the tissue samples procured from these lesions to represent the first tissue available to study a malignancy from an unknown primary. In general surgical pathology, the evaluation of a metastatic neoplasm of unknown primary is a very complicated process, requiring knowledge of numerous different tumor types, reagents, and staining patterns. The past few years, however, have seen a remarkable refinement in the immunohistochemical tools at our disposal that now empower neuropathologists to take an active role in defining the relatively limited subset of neoplasms that commonly metastasize to the central nervous system. This information can direct imaging studies to find the primary tumor in a patient with an unknown primary, clarify the likely primary site of origin in patients who have small tumors in multiple sites without an obvious primary lesion, or establish lesions as late metastases of remote malignancies. Furthermore, specific treatments can begin and additional invasive procedures may be prevented if the neuropathologic evaluation of metastatic neoplasms provides information beyond the traditional diagnosis of ''metastatic neoplasm.'' In this review, differential cytokeratins, adjuvant markers, and organ-specific antibodies are described and the immunohistochemical signatures of metastatic neoplasms that are commonly seen by neuropathologists are discussed

    Full Text Available With the discovery of the JAK2V617F mutation in patients with Philadelphia chromosome-negative (Ph− myeloproliferative neoplasms (MPNs in 2005, major advances have been made in the diagnosis of MPNs, in understanding of their pathogenesis involving the JAK/STAT pathway, and finally in the development of novel therapies targeting this pathway. Nevertheless, it remains unknown which mutations exist in approximately one-third of patients with non-mutated JAK2 or MPL essential thrombocythemia (ET and primary myelofibrosis (PMF. At the end of 2013, two studies identified recurrent mutations in the gene encoding calreticulin (CALR using whole-exome sequencing. These mutations were revealed in the majority of ET and PMF patients with non-mutated JAK2 or MPL but not in polycythemia vera patients. Somatic 52-bp deletions (type 1 mutations and recurrent 5-bp insertions (type 2 mutations in exon 9 of the CALR gene (the last exon encoding the C-terminal amino acids of the protein calreticulin were detected and found always to generate frameshift mutations. All detected mutant calreticulin proteins shared a novel amino acid sequence at the C-terminal. Mutations in CALR are acquired early in the clonal history of the disease, and they cause activation of JAK/STAT signaling. The CALR mutations are the second most frequent mutations in Ph− MPN patients after the JAK2V617F mutation, and their detection has significantly improved the diagnostic approach for ET and PMF. The characteristics of the CALR mutations as well as their diagnostic, clinical, and pathogenesis implications are discussed in this review.

    Vulvodynia is a complex and multifactorial clinical condition with severe pain that occurs in the absence of visible infectious, inflammatory, neoplastic, or neurological findings. A 35-year-old woman with 3 years of dysesthetic vulvodynia tried conventional and interventional medical treatment with inadequate relief. She was offered peripheral subcutaneous vulvar field stimulation and underwent implantation of two vulvar subcutaneous electrodes. At 15 days after treatment and during 1-year follow-up, the patient scored 1 out of 15 on Friedrich scale, 1 out of 10 on the visual analog scale, and 1 out of 10 on the tampon test. The patient no longer requires oral medication. Stimulation with subcutaneous electrodes provided relief from vulvodynia to a patient in whom all previous therapeutic approaches had failed.

    The aim of the study was to determine health-related quality of life (HRQoL) of women with surgically treated vulvar intraepithelial neoplasia (VIN) and vulvar cancer (VC) during the first week after hospital discharge. Further objectives were to investigate differences between women with VIN and VC as well as to examine whether correlations exist between women's symptom experience and HRQoL. This cross-sectional study was conducted in 8 hospitals in Germany and Switzerland. Women with VIN and VC rated HRQoL with the validated German Short-Form 36. Differences between HRQoL in women with VIN and VC were tested with Wilcoxon rank-sum score. The WOMen with vulvAr Neoplasia (WOMAN) - Patient reported Outcome (PRO) self-report instrument was used to measure women's symptom experience. Correlations between symptoms and HRQoL were calculated using Spearman correlation coefficient. Women with VIN and VC (n = 65) reported lower HRQoL in physical aspects (Physical Component Summary [PCS], 34.9) than that in mental aspects (Mental Component Summary, 40.5). Women with VC had lower HRQoL than women with VIN, as manifested by significant differences concerning the dimensions of "physical functioning" and "role-physical." "Difficulties in daily life" as a distressing symptom correlated with MCS and PCS. Wound-related symptoms correlated with PCS and psychosocial symptoms/issues with MCS. Analysis showed that women with vulvar neoplasia reported lower HRQoL in the physical and mental dimensions 1 week after discharge than comparable studies referring to months or years after surgery. Health-related quality of life is influenced by physical impairment because physical symptoms are prevalent 1 week after discharge. Patient education should focus on symptom management in an early postsurgical phase to enhance women's HRQoL.

    Vulvar lymphatic leakage is a severe complication associated with gynecological cancer treatments. However, standard treatment strategies have not yet been determined. We encountered a rare case of a 76-year-old multiparous woman suffering from massive lymphatic fluid leakage from the entire vulva, and papules developed and were identified as lymphangiomas. A large amount of straw-colored discharge continued from all vulvar papules, which extended over the mons pubis. Nine years ago, the patient had undergone a radical hysterectomy with concurrent chemoradiation for uterine cervical cancer treatment. Her serum albumin level was 1.9 mg/dl, which was attributed to the loss of a large amount of lymph fluid due to leakage from the vulva. Her quality of life gradually decreased because of general fatigue and the need for frequent diaper exchanges every 2 h. The patient received a less-invasive treatment with cryotherapy using liquid nitrogen. She also received a multimodality treatment consisting of the intravenous administration of albumin, massage of the lower limbs and intensive rehabilitation. Cryotherapy was administered once a week for 3 months. Her discharge almost stopped and vulvar lymphangiomas decreased without any major complications. To the best of our knowledge, this is the first case report of massive lymphatic leakage complicated with vulvar lymphangiomas. Additionally, this case may represent the first successful treatment of vulva lymph leakage by cryotherapy without recurrence. Cryotherapy may have the potential to improve the quality of life as a less-invasive treatment for gynecological cancer survivors without serious complications. © The Author 2014.

    Salivary gland neoplasms are uncommon but important presentation to general surgeons. Objective: To analyze the relative frequency and distribution of Salivary gland neoplasms in our division. Setting: Department of surgery and pathology, Peoples Medical University hospital and GMMMC hospital Sukkur. Study design: Descriptive (case series) Subjects and methods: A total of 40 patients registered for salivary gland tumors from oct 2008 to 0ct 2013 were included in the study. A thorough history, clinical examination, routine haematological and biochemical studies were done in all patients. FNAC was done in all cases. All patients were subjected to surgical intervention on standard rules. Each resected specimen was sent for histopathology. Information about age, gender and tumor location was obtained from clinical record and frequency of different neoplasms was studied from histopathological report. All data was collected on especially designed proforma. Data analysis was done using spss version 17. Results: A total of 40 patients were registered for salivary gland neoplasms. 28 patients (70%) had parotid lesions, 10 patients (25%) had submandibular gland involvement and 2 patients ( 5%) had minor salivary gland tumors. Patients were between 15 - 80 years of age( mean age =34.7 years) 24 patients(60%) were male and 16 (40%) were female,with male to female ratio of 1.5:1.32 . 22 (80%) had benign lesions and 8 patients (20%) had malignant lesions. Pleomorphic adenoma was the most common benign tumor affecting the parotid gland. Adenocarcinoma represented as the most prevelant parotid malignancy. Benign neoplasms occurred in third and fourth decades of life and malignant neoplasms were diagnosed in sixth and seventh decades of life. Conclusion:Salivary gland neoplasms are uncommon but they have occasioned much interest and debate because of broad histological spectrum. The data presented in this study is corroborated with most of the studied literature worldwide. (author)

  14. Use of Cetuximab in Combination with Cisplatin and Adjuvant Pelvic Radiation for Stage IIIB Vulvar Carcinoma

    Directory of Open Access Journals (Sweden)

    Jennifer Bergstrom

    2015-01-01

    Full Text Available Vulvar cancer is a rare carcinoma constituting only 4% of gynecologic malignancies and 0.6% of female cancers. Most chemotherapy regimens have been created from extrapolation from anal and cervical cancer research. Advanced stages have the worst prognosis and oftentimes invasive surgical procedures are needed to cure disease with high recurrence rates. Case. A 50 yo G2P2 presented for a 2 cm mass in her right labia. The patient underwent a partial radical vulvectomy and bilateral superficial and deep inguinal lymph node dissection. Bilateral inguinal lymph nodes were positive for residual disease. The patient underwent whole pelvic radiation with cisplatin as a radiosensitizer. The primary tumor was epidermal growth factor receptor (EGFR positive and cetuximab, a monoclonal antibody to EGFR, was added. The patient underwent seven cycles of chemotherapy including cisplatin and cetuximab with adjuvant radiation therapy to the pelvis. She currently is without evidence of disease recurrence since completing treatment 4 years ago. Conclusion. One previous case report showed short-term palliative success of five months for recurrent, metastatic vulvar cancer. This case suggests that cetuximab could possibly be used in initial management of patients with advanced stages of vulvar cancer to improve prognosis.

    2012-03-15

    To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

    Objective: In order to know the nutriture of neoplasm patients receiving radiotherapy and give nutritional guidance properly, the authors make the following survey. Methods: A dietary survey of twenty-four-hour retrospective method was used; The patients' activity was recorded and their twenty-four hours caloric consumption was calculated. Results: Of all the patients, the intake of protein is more than recommended, percentage of calorific proportion is about 15%-19% of gross caloric. A larger portion of patients' caloric intake, especially female patients, is lower than caloric consumption. Among all the patients, the intake of vegetables is not enough; The consumption of milk and milky products is lower; it is common and serious that neoplasm patients receiving radiotherapy have vitamine and mineral's scarcity. Conclusions: Nutriture of neoplasm patients is not optimistic, it is imperative to improve their nutriture

    The purpose of this case report is to report an orbital roof encephalocele mimicking a destructive orbital neoplasm. Orbital roof encephalocele is uncommon but can mimic neoplasm. One potential mechanism for the orbital roof destruction is a post-traumatic "growing orbital roof fracture." The growing fracture has been reported mostly in children but can occur in adults. Alternative potential etiologies for the encephalocele are discussed, including Gorham syndrome. Orbital roof encephalocele is uncommon in adults, and the findings can superficially resemble an orbital neoplasm. Radiographic and clinical features that might suggest the correct diagnosis include a prior history of trauma, overlying frontal lobe encephalomalacia without significant mass effect or edema, and an orbital roof defect. The "growing fracture" mechanism may be a potential explanation for the orbital roof destruction in some cases.

    1991-06-01

    Neoplasms of the thoracic cavity are as diverse as the structures and tissues that comprise the thorax. This paper summarizes the clinical signs, diagnosis and treatment of thoracic neoplasms in the dog and cat. Specific diagnostic techniques are evaluated, as is the utility of imaging techniques for clinical staging. Surgery is recommended as the treatment of choice for intrathoracic neoplasms, with exception for multiple tumor masses, metastasis, or poor patient health. Radiation therapy, chemotherapy, and hyperthermia are discussed individually or in combination with surgery or each other. Prognosis for specific tumors is discussed, as is lymph node involvement as a prognostic indicator. As the use of newer diagnostic procedures become more available in veterinary medicine, it should be possible to offer patients a variety of positive choices that will enhance their survival and quality of life

    Glick, S.N.; Teplick, S.K.; Ross, W.M.

    1986-01-01

    The authors prospectively evaluated 62 patients over 40 years old in whom lymphoid follicles were demonstrated on double-contrast enema examinations. Eighteen patients (29%) had no current radiographic evidence of, or history of, colonic neoplasms. Forty-four patients (71%) had an associated neoplasm. Fourteen patients had associated colonic carcinoma, and ten patients had a history of a previously resected colon cancer. One patient had previously undergone resection for ''polyps.'' Twenty-two patients had an associated ''polyp.'' There were no clinical or radiographic features that could reliably distinguish the neoplastic from the nonneoplastic groups. However, lymphoid follicles in the left colon or diffusely involving the colon were more likely to be associated with a colonic neoplasm. Lymphoid follicles were almost always identified near a malignant lesion

    Diagnostic imaging is an important tool to evaluate pancreatic neoplasms. We describe the imaging features of pancreatic malignancies and their benign mimics. Accurate detection and staging are essential for ensuring appropriate selection of patients who will benefit from surgery and for preventing unnecessary surgeries in patients with unresectable disease. Ultrasound, multidetector computed tomography with multiplanar reconstruction and magnetic resonance imaging can help to do a correct diagnosis. Radiologists should be aware of the wide variety of anatomic variants and pathologic conditions that may mimic pancreatic neoplasms. The knowledge of the most important characteristic key findings may facilitate the right diagnosis.

    Nygard, Mari; Hansen, Bo Terning; Dillner, Joakim

    2014-01-01

    BACKGROUND: Infection with high-risk human papillomavirus (HPV) is causally related to cervical, vulvar and vaginal pre-invasive neoplasias and cancers. Highly effective vaccines against HPV types 16/18 have been available since 2006, and are currently used in many countries in combination...... with cervical cancer screening to control the burden of cervical cancer. We estimated the overall and age-specific incidence rate (IR) of cervical, vulvar and vaginal cancer and pre-invasive neoplasia in Denmark, Iceland, Norway and Sweden in 2004-2006, prior to the availability of HPV vaccines, in order...... to establish a baseline for surveillance. We also estimated the population attributable fraction to determine roughly the expected effect of HPV16/18 vaccination on the incidence of these diseases. METHODS: Information on incident cervical, vulvar and vaginal cancers and high-grade pre-invasive neoplasias...

    2005-01-01

    The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material. Images were analyzed in consensus by two radiologists. Diagnoses were made from biopsy, surgery and/or clinical follow-up findings. Multiple myeloma was found in seven patients and extramedullary plasmacytoma in four patients. All patients with multiple myeloma had multifocal disease with involvement of perirenal space (4/7), retroperitoneal and pelvic lymph nodes (3/7), peritoneum (3/7), liver (2/7), subcutaneous tissues (2/7) and kidney (1/7). In three of the four patients with extramedullary plasmacytoma, a single site was involved, namely stomach, vagina and retroperitoneum. In the fourth patient, a double site of abdominal involvement was observed with rectal and jejunal masses. Plasma cell neoplasm should be considered in the differential diagnosis of single or multiple enhancing masses in the abdomen or pelvis. Abdominal plasma cell neoplasms were most frequently seen as well-defined enhancing masses (10/11). (orig.)

    McGrath, Pam; Rawson, Nicole

    2013-01-01

    Vulvar cancer is a serious condition that requires a range of specialist treatments including surgery, chemotherapy, and radiation. In Australia, such treatments are only available in major metropolitan hospitals. Thus, women diagnosed with this condition in rural and remote areas must relocate to the metropolitan specialist centers for treatment. The focus of this article is on the experience of relocation for specialist care for Indigenous women diagnosed with vulvar cancer from East Arnhem Land, Northern Territory, Australia. The findings presented in this article explore a range of issues that affect the experience of relocation such as community concerns, cultural distress, loneliness, fear, worry, and physical concerns associated with the condition.

    Vulvar intraepithelial neoplasia (VIN) and vulvar Paget disease are managed with either vulvectomy, destructive treatments (laser, antimitotic drugs) or immunostimulants. All these options are associated with functional complications. The purpose of this study was to evaluate the surgical technique consisting of skinning vulvectomy with split-thickness skin graft, and its effect on overall quality of life and sexual function. A retrospective study was conducted on thirteen patients who underwent skinning vulvectomy with split-thickness skin graft between 1999 and 2009. Overall quality of life and sexual function were assessed with the Medical Outcome Study Short Form 36 (MOS SF-36) and Female Sexual Function Index (FSFI), respectively. The median age of patients was 54 (range: 33-77) years. Three patients had Paget disease and 10 patients had VIN lesions. The excision margins were clear in 46% of cases. The incidence of occult cancer was 31%. The mean follow-up period was 77 (±35) months. Four patients experienced a relapse of their intraepithelial disease. The mean disease-free survival was 58 (±44) months. There was no significant difference in MOS SF-36 scores between the study population and the general population. The patients assessed with the FSFI regained normal sexual function after the surgical procedure. Skinning vulvectomy with split-thickness skin graft is a feasible technique yielding good results in terms of quality of life and sexual function. It enables occult cancer to be diagnosed in patients with VIN or Paget disease. Copyright © 2013 Elsevier Ltd. All rights reserved.

  14. ABO blood groups as a prognostic factor for recurrence in ovarian and vulvar cancer.

    The relationship between ABO blood groups (BG) and risk of incidence in cancers including gynecological cancers has been widely studied, showing increased incidence risk for BG A patients. As available data are inconsistent we investigated whether BG and their anti-glycan antibodies (anti-A and anti-B) have prognostic values in gynecological cancers. We retrospectively evaluated 974 patients with gynecological cancers in three cancer centers (Switzerland and Australia) between 1974 and 2014 regarding the relationships between clinico-pathological findings and the BG. Time to disease recurrence was significantly influenced by BG in patients with ovarian (n = 282) and vulvar (n = 67) cancer. BG O or B patients showed a significantly increased risk for ovarian cancer relapse compared to A, 59% and 82%, respectively (p = 0.045; HR O vs A = 1.59 (CI 1.01-2.51) and (p = 0.036; HR A vs B = 0.55 (CI 0.32-0.96). Median time to relapse for advanced stage (n = 126) ovarian cancer patients was 18.2 months for BG O and 32.2 for A (p = 0.031; HR O vs A = 2.07 (CI 1.07-4.02)). BG also significantly influenced relapse-free survival in patients with vulvar cancer (p = 0.002), with BG O tending to have increased relapse risk compared to A (p = 0.089). Blood groups hence associate with recurrence in ovarian and vulvar cancer: women with BG O seem to have a lower ovarian cancer incidence, however are more likely to relapse earlier. The significance of the BG status as a prognostic value is evident and may be helpful to oncologists in prognosticating disease outcome and selecting the appropriate therapy.

  15. Influence of treatments on prognosis for vulvar lichen sclerosus: facts and controversies.

    Brodrick, Brooks; Belkin, Zoe R; Goldstein, Andrew T

    2013-01-01

    Lichen sclerosus (LS) is an inflammatory dermatosis with a predilection for the anogential skin. Vulvar LS can be a debilitating disease, causing pruritus and pain, and it carries the potential for atrophy, scarring, and significant functional impairment. Recently, many advances have been made regarding the etiology and natural history of the disease process; however, much debate still exists regarding the most advantageous medical and surgical management of this disorder. In an effort to provide a comprehensive review on current vulvar LS literature, the following three controversies will be discussed: (1) optimal disease treatment, (2) theories behind LS's oncogenicity and treatments for minimizing malignancy, and (3) the value of surgical treatment for LS. Ultra-potent topical corticosteroids (TCSs) are the first-line treatment for vulvar LS, while topical calcineurin inhibitors (TCIs) remain second-line agents for patients for whom TCS treatment resulted in incomplete resolution of symptoms or adverse events. Due to the relapsing nature of the disease, long-term maintenance therapy is often required. In addition, recent advances have contributed to the understanding of the association between LS and squamous cell carcinoma (SCC). While the exact mechanism responsible for LS-associated SCC is not known, immune dysregulation and inflammation may play an important role; therefore, successful treatment of LS should be directed towards alleviation of symptoms and reversal of the underlying histopathologic changes. Patients with LS-associated malignancy, as well as patients who need correction of functionally restrictive, scarring processes, can successfully undergo surgical intervention with tissue conservation. © 2013 Elsevier Inc.

    To investigate whether botulinum neurotoxin type A improves vaginismus and study its efficacy with repeated treatments. Outpatients were referred because standard cognitive-behavioral and medical treatment for vaginismus and vulvar vestibular syndrome failed. From this group, we prospectively recruited consecutive women (n=39) whose diagnostic electromyogram (EMG) recordings from the levator ani muscle showed hyperactivity at rest and reduced inhibition during straining. These women were followed for a mean (+/-standard deviation) of 105 (+/-50) weeks. Recruited patients underwent repeated cycles of botulinum neurotoxin type A injected into the levator ani under EMG guidance and EMG monitoring thereafter. At enrollment and 4 weeks after each cycle, women were asked about sexual intercourse; underwent EMG evaluation and examinations to grade vaginal resistance according to Lamont; and completed a visual analog scale (VAS) for pain, the Female Sexual Function Index Scale, a quality-of-life questionnaire (Short-Form 12 Health Survey), and bowel and bladder symptom assessment. At 4 weeks after the first botulinum neurotoxin type A cycle, the primary outcome measures (the possibility of having sexual intercourse, and levator ani EMG hyperactivity) both improved, as did the secondary outcomes, Lamont scores, VAS, Female Sexual Function Index Scales, Short-Form 12 Health Survey, and bowel-bladder symptoms. These benefits persisted through later cycles. When follow-up ended, 63.2% of the patients completely recovered from vaginismus and vulvar vestibular syndrome, 15.4% still needed reinjections (censored), and 15.4% had dropped out. Botulinum neurotoxin type A is an effective treatment option for vaginismus secondary to vulvar vestibular syndrome refractory to standard cognitive-behavioral and medical management. After patients received botulinum neurotoxin type A, their sexual activity improved and reinjections provided sustained benefits. III.

  17. Key factors impacting on diagnosis and treatment for vulvar cancer for Indigenous women: findings from Australia.

    2013-10-01

    To date, there has been limited research on the topic of vulvar cancer. This paper provides findings from a qualitative study conducted with Indigenous women in East Arnhem Land, Northern Territory, Australia on the psychosocial impact of diagnosis and treatment for vulvar cancer. The insights from the study outlined in this paper not only make a contribution to deepening our understanding of the experience of vulvar cancer for Indigenous women, but provide practical recommendations to ensure effective and early engagement for diagnosis and treatment. A qualitative research method was employed through in-depth, open-ended interviews. The participants of the study were a purposive sample of Indigenous women with the condition, health professionals, and Aboriginal health workers. There were a total of 40 participants; with twelve (n = 12) Indigenous women affected with the condition, fourteen (n = 14) Aboriginal Health Workers, ten (n = 10) nurses, three (n = 3) doctors, and one (n = 1) community member. This paper addresses three key issues highlighted by the participants which include the fact that the private nature of the disease makes the condition 'women's business', that there is a sense of shame associated with the condition, and that there is fear and worry generated by the seriousness of the condition. The private nature of the disease and the sense of shame associated with the condition impact upon the diagnosis and treatment for many Indigenous women. In addition, the limitation of resources for health service delivery for East Arnhem Land exacerbates the problems faced by these communities. This paper puts forward suggestions to facilitate early diagnosis and treatment for women affected with the condition.

    Full Text Available Abstract Background Besides being a causative agent for genital warts and cervical cancer, human papillomavirus (HPV contributes to 40-85% of cases of anal, penile, vaginal and vulvar cancer and precancerous lesions. HPV types 16 & 18 in particular contribute to 74-93% of these cases. Overall the number of new cases of these four cancers may be relatively high implying notable health care cost to society. The aim of this study was to estimate the incidence and the health care sector costs of anal, penile, vaginal and vulvar cancer. Methods New anogenital cancer patients were identified from the Danish National Cancer Register using ICD-10 diagnosis codes. Resource use in the health care sector was estimated for the year prior to diagnosis, and for the first, second and third years after diagnosis. Hospital resource use was defined in terms of registered hospital contacts, using DRG (Diagnosis Related Groups and DAGS (Danish Outpatient Groups System charges as cost estimates for inpatient and outpatient contacts, respectively. Health care consumption by cancer patients diagnosed in 2004–2007 was compared with that by an age- and sex-matched cohort without cancer. Hospital costs attributable to four anogenital cancers were estimated using regression analysis. Results The annual incidence of anal cancer in Denmark is 1.9 per 100,000 persons. The corresponding incidence rates for penile, vaginal and vulvar cancer are 1.7, 0.9 and 3.6 per 100,000 males/females, respectively. The total number of new cases of these four cancers in Denmark is about 270 per year. In comparison, the total number of new cases cervical cancer is around 390 per year. The total cost of anogenital cancer to the hospital sector was estimated to be 7.6 million Euros per year. Costs associated with anal and vulvar cancer constituted the majority of the costs. Conclusions Anogenital cancer incurs considerable costs to the Danish hospital sector. It is expected that the current

    Fifty-three women with partial vaginismus with or without vulvar vestibulitis and 27 asymptomatic women estimated sensations of burning pain and itch at 20 standardized moments during a standardized penetration situation, including vaginal muscle contractions. Forty-three women with partial vaginismus (81.1%) reported burning pain, 23 (43.4%) itch, and 22 (41.5%) both complaints, compared to 0% of the asymptomatic women. In 17 of 22 cases, burning pain preceded the appearance of itch and in four cases the two complaints coincided. The median time from the moment when burning pain started until itch appeared was 150 seconds.

    This article discusses the clinical evaluation and approach to patients with 3 complex ulcerative vulvar conditions: hidradenitis suppurativa, metastatic Crohn disease of the vulva, and aphthous ulcers. These conditions are particularly challenging to medical providers because, although each is known to present with nonspecific examination findings that vary in morphology, the predominance of the diagnosis is based on clinical examination and exclusion of a wide variety of other conditions. Care of patients with these conditions is further complicated by the lack of therapeutic data and the significant impact these conditions have on quality of life. Copyright © 2017 Elsevier Inc.

    Very little is known regarding the epidemiology, etiology, and mechanisms of spontaneous intrathoracic neoplasia in companion animals. Much of what we know or suspect about thoracic neoplasia in animals has been extrapolated from experimentally-induced neoplasms. Most studies of thoracic neoplasia have focused on the pathology of primary and metastatic neoplasms of the lung with little attention given to diagnostic and therapeutic considerations. Although the cited incidence rate for primary respiratory tract neoplasia is low, 8.5 cases per 100,000 dogs and 5.5 cases per 100,000 cats, intrathoracic masses often attract attention out of proportion to their actual importance since they are often readily visualized on routine thoracic radiographs.

    Full Text Available A retrospective study of necropsy and biopsy cases of 90 primary bone tumors (89 malignant and one benign in dogs received over a period of 22 years at the Laboratório de Patologia Veterinária, Universidade Federal de Santa Maria, was performed. Osteosarcoma was the most prevalent bone tumor, accounting for 86.7% of all malignant primary bone neoplasms diagnosed. Most cases occurred in dogs of large and giant breeds with ages between 6 and 10-years-old. The neoplasms involved mainly the appendicular skeleton, and were 3.5 times more prevalent in the forelimbs than in the hindlimbs. Osteoblastic osteosarcoma was the predominant histological subtype. Epidemiological and pathological findings of osteosarcomas are reported and discussed.

    Abstract - The incidence of malignancies in virus carriers acquired immunodeficiency (HIV) has increased in conjunction with the disease during the past decade. 40% of all AIDS patients develop cancer during the course of HIV infection. Kaposi's sarcoma (KS), Non-Hodgkin lymphoma (NHL) and cervical cancer have an impact extremely high in HIV infected patients, and they are considered as disease AIDS-defining stage. Many reports suggest that other neoplasms they can have a high impact on the population of HIV carrier, including head and neck carcinoma, rectal cancer - anal, plasma cytomas, and melanoma lung cancer. Methods - We examined the spectrum of cancer in HIV-infected patients, specifically neoplasms except Kaposi sarcoma diagnosed between 1/1998 - 6/2004. Information on age, sex, factors was gathered risk for AIDS, neoplasms and mortality rate. Results: The total number of patients in our study was 21 patients, what 15 were male (71%) and 6 females (29%); the median age was 36 (29-70). Tumors were reported: 11 Non-Hodgkin lymphomas (52%), 2 Hodgkin's lymphoma (6.6%), 1 medullary thyroid cancer (6.6%), 1 melanoma (6.6%), 1 rectal cancer (5%) and three head and neck cancers (14%), 1 cancer 1 lung and breast cancer. Five of the patients were intravenous drug abusers (24%); 4 patients were homosexual, bisexual March 8 straight, on 6 patients know the data. Conclusions - The spectrum of malignancies associated with infection HIV in our study was similar to that described in other populations. ratio between the immune system and the epidemiology of the virus-induced tumors is to importance to identify new therapeutic approaches in the treatment and / or prevention of these neoplasms

    2004-01-01

    We describe a case of small bowel obstruction associated with a carcinoid neoplasm of the ileum in a 78 year old man who was presented with abdominal pain, vomiting, and a mass in right lower quadrant. Carcinoids are neuroendocrine neoplasm originating in multiple locations throughout the body human. About 75% of such neoplasm are located within the gastrointestinal tract and are capable of rpoducing various peptides. Their clinical course is often indolent but can also be aggressive and resistant to therapy. The incidence of these tumours is approximately 2.5 in 100.000 people per year. The former classification system of fore gut, midgut and hind gut tumors is still used in clinical routine. Determination of the histopathology of carcinoid tumors is of utmost importance and involves specific immunohistochemical staining for chromogranin A, synaptophysin, serotonin and gastrin. New localization procedures include somatostatin receptor scintigraphy and positron emission tomography. Surgery remains the cornerstone of treatment and provides the only chance of a cure. Other cytoreductive procedures include radiofrequency ablation, laser treatment and chemo embolization. New therapies, such as ling acting somatostatin analogs, together with further development of tumor targeted treatments, will come into clinical use in the near future. (The author)

    Cryotherapy is an increasingly popular mode of therapy adjunctive to surgical curettage in the treatment of certain skeletal neoplasms, such as giant cell tumors or chondrosarcomas. The magnetic resonance (MR) findings following cryotherapy have not been previously reported. We reviewed the MR findings in seven patients with skeletal neoplasms following curettage and cryotherapy. In six cases we found a zone of varying thickness extending beyond the surgical margins, corresponding to an area of cryoinjury to medullary bone. This zone displayed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, consistent with the presence of marrow edema. This zone of edema almost certainly reflects underlying thermal osteonecrosis. This zone may vary in size and intensity over time as the area of cryoinjury evolves or resolves. MR is currently the imaging procedure of choice for follow-up of most musculoskeletal neoplasms. Knowledge of the MR findings following cryotherapy should help prevent confusion during the interpretation of follow-up MR examinations. (orig.)

    2016-06-01

    Familial syndromes of hyperparathyroidism, including multiple endocrine neoplasia type 1 (MEN1), multiple endocrine neoplasia type 2A (MEN2A), and the hyperparathyroidism-jaw tumor (HPT-JT), comprise 2-5% of primary hyperparathyroidism cases. Familial syndromes of hyperparathyroidism are also associated with a range of endocrine and nonendocrine tumors, including potential malignancies. Complications of the associated neoplasms are the major causes of morbidities and mortalities in these familial syndromes, e.g., parathyroid carcinoma in HPT-JT syndrome; thymic, bronchial, and enteropancreatic neuroendocrine tumors in MEN1; and medullary thyroid cancer and pheochromocytoma in MEN2A. Because of the different underlying mechanisms of neoplasia, these familial tumors may have different characteristics compared with their sporadic counterparts. Large-scale clinical trials are frequently lacking due to the rarity of these diseases. With technological advances and the development of new medications, the natural history, diagnosis, and management of these syndromes are also evolving. In this article, we summarize the recent knowledge on endocrine neoplasms in three familial hyperparathyroidism syndromes, with an emphasis on disease characteristics, molecular pathogenesis, recent developments in biochemical and radiological evaluation, and expert opinions on surgical and medical therapies. Because these familial hyperparathyroidism syndromes are associated with a wide variety of tumors in different organs, this review is focused on those endocrine neoplasms with malignant potential. © 2016 Society for Endocrinology.

    Topical remedies based on botanical ingredients are popular. To assess: (i) the usage of botanical substances in subjects affected with itching and chronic vulvar complaints; (ii) the incidence of side-effects associated with their use and the frequency of contact allergy; (iii) the diagnostic usefulness of patch testing. Sixty-six patients were provided with a questionnaire to assess the prevalence and type of topical botanical preparations used and the occurrence of adverse reactions. Patients were patch tested with (i) the Italian baseline series, (ii) a topical medicament series, and (iii) a botanical series. Forty-two patients (63.6%) reported the use of natural topical products on the vulva. Seven (16.7%) noted adverse reactions; 27 showed positive reactions with the baseline series; 14 (21.2%) had at least one relevant reaction, mainly to allergens in topical products and cosmetics; and 2 (3%) showed positive reactions to the botanical series. Of the 7 patients complaining of adverse effects of botanical products, 3 (42.8%) showed relevant sensitization. The use of natural topical products is widespread among women affected with itching vulvar diseases. Contact dermatitis is a possible adverse effect. Botanical series are of questionable usefulness, owing to the wide variety of botanical ingredients. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Squamous cell vulvar cancers (SCVC) are rare. Although management guidelines have recently been published, New Zealand studies presenting "real world" outcomes are limited. Retrospective single-centre review of SCVC diagnosed between 1 January 2000 and 31 August 2015. Clinical characteristics and outcomes were reviewed. Among 47 cases reviewed, 38 were ethnically European and 9 Māori. Cases identified as Stage 1 (16), Stage 2 (5), Stage 3 (17), Stage 4 (9). For Stages 1, 2, 3 and 4, (16, 4, 17 and 6) were managed by local excision; (9, 1, 14 and 2) by node dissection and (2, 1, 3 and 5) by chemoradiotherapy respectively. Wound cellulitis (10) and lymphedema (8) were the commonest acute and late complication, respectively. Seven patients were treated with 5-Fluorouracil and Mitomycin, and four received weekly Cisplatin. Grade 3 toxicities seen in five cases treated with 5-Fluorouracil and Mitomycin versus none in the Cisplatin group. No local recurrences observed in patients treated with chemoradiation. Patients with Age Adjusted Charlson Comorbid Index Score (ACCIS) <5 had better overall survival (OS) compared to scores ≥5 (60% versus 41%) with 33 months median follow-up. Five-year OS and disease-free specific survival was 73% and 94% (Stage 1), 40% and 60% (Stage 2), 44% and 59% (Stage 3) and 29% (Stage 4) respectively. We present "real world" outcomes of vulvar cancers in this older and comorbid population. Larger, prospective multi-centre studies are proposed.

  14. Recurrent vulvar carcinoma: complex surgical treatment via perineal excision and reconstruction with musculocutaneous flap

    Full Text Available Vulvar cancer is a malignant disease having a low frequency and with well-established surgical and oncological treatments based on the stage of the disease. The most important therapeutic problem encountered is represented by cases of perineal local regional recurrence, which are common in patients with large primary tumors and can occur even if the margins of the resection had no tumoral invasion. We present a case study of a 64-year-old patient diagnosed one year ago with squamous vulvar carcinoma (G3 for which a vulvectomy was performed after neoadjuvant radiotherapy. The patient later developed local recurrence with invasion of the anal sphincter, creating a delicate problem regarding a surgical approach. The size and the extent of the recurrent tumor required a complex surgical intervention using a mixed surgical team of general surgeons and plastic surgeons. Surgical intervention with a large excision of the recurrent cancer along with amputation of the inferior rectum via perineal route, and creation of a left iliac anus was performed. The perineal defect was covered via a musculocutaneous flap using the gracilis muscle. The immediate post-operative evolution was favorable.

    2015-05-01

    Provoked vestibulodynia (PVD) is a common condition characterized by localized, provoked pain that can be present since first vaginal penetration attempt (primary) or can develop after a period of pain-free penetration (secondary). Research has demonstrated psychosocial and psychophysical differences between women with these subtypes of PVD, but the question of whether neural responses to pain also differ remains to be investigated. This study aims to examine whether cognitive, psychophysical, and neural responses to vulvar pressure pain differ between women with PVD1 and PVD2. Women with PVD1 and PVD2 were compared for group differences using multiple modalities, including questionnaires, psychophysical testing, and neuroimaging. Pain ratings were held constant across groups, rather than amount of pressure applied. Demographics, sexual functioning, four questionnaires examining anxiety and catastrophizing, quantitative sensory testing at the vulvar vestibule using a vulvalgesiometer, and functional and structural magnetic resonance imaging (MRI). Findings suggest that women with PVD1 are more anxious and that they catastrophize more about their vulvar and nonvulvar pain than women with PVD2. Overall, MRI results demonstrated structural and functional similarities to other chronic pain findings for both groups of women. Gray matter (GM) density also differed between groups: women with PVD1 showed significant decreases in GM throughout areas associated with pain processing. Functionally, between-groups differences were found during painful vulvar stimulation despite lower pressures applied to the vulva for women with PVD1 because of their heightened sensitivity; the determination of the level of vulvar pressure to elicit pain was based on subjective ratings. Findings are limited by sample size and liberal alpha values; however, future research is certainly warranted based on the preliminary findings of this study suggesting both similarities and differences between

    The aim is to present the variety of signs and symptoms from the diagnostic imaging methods of atypical neoplasms of the pancreas, presented as a type of cystic lesions. This often leads to unnecessary surgery or inappropriate tracking. In 115 patients (85 men and 30 women) with cystic lesions of the pancreas ultrasonic (US),computer tomography (CT) and magnetic resonance imaging (MRI) were performed and verified through histological and macroscopic pathology preparations. The ultrasound machines equipped with linear and convex transducers, MDCT and MRI imaging systems were used. In 14 of 115 patients atypical neoplasms of the pancreas were diagnosed: two cases with macroscopic serous cystic neoplasms, two nonmucinous cystic neoplasms, two hemorrhagic mucinous neoplasms, two ductal adenocarcinomas with cystic changes, one islet cell cystic tumor, two lymphoepithetial cysts, one lymphangioma, one solid papillary epithelial neoplasm and one mucinous adenocarcinoma. The authors take into consideration and overlapping of clinical symptoms and laboratory tests. Although much of the imaging features and morphological characteristics of cystic neoplasms of the pancreas are well known, should be known about the atypical unusual images in so-called 'typical' cystic neoplasms, cystic images in solid neoplasms and various atypical tumors with cystic lesions.

    Vulvar cancer (VC) is a rare disease. The most common histologic type is squamous-cell carcinoma. VC could be divided into two types: type one, commonly associated with HPV infection, occurs in young women and type two, associated with non-neoplastic lesions that usually occurs in older women. Previously VC was often treated with radical Vulvectomy. Today update in diagnostic and surgery technique, capable to identify early stages of disease and adaptation in surgery procedures, according to the stage of disease, age of patients and possible physical and psychological morbidity consequence, allow using less radical surgery approaches. That has led to decrease therapy-associated morbidity while preserving oncologic safety and improving psychosexual outcomes. Finally, several surgical treatments are available in case of VC and, despite radical surgery is often required, less radical surgery associated with reconstructive plastic surgery decreases some of short- and long-term associated complications.

  8. Perceptions of dyspareunia in postmenopausal women with vulvar and vaginal atrophy: findings from the REVIVE survey.

    2014-07-01

    Symptoms of vulvar and vaginal atrophy (VVA), including dyspareunia and vaginal dryness, have a distinct negative impact on a woman's quality of life. The REVIVE survey highlighted the lack of awareness of VVA symptoms among postmenopausal women with vaginal symptoms, with many women reluctant to initiate discussions with their healthcare professionals despite the presence of vaginal symptoms. The REVIVE survey also provided insights into women's views of VVA treatments. Women reported displeasure with the vaginal administration route, lack of symptom relief with over-the-counter products, and concerns about the safety of estrogen therapies. With the high prevalence of VVA, obstetricians/gynecologists should become vigilant in identifying women with VVA by implementing screening and discussion of symptoms during routine office visits - providing patients with information about appropriate therapies based on the severity and impact of symptoms, keeping in mind individual preferences and perceptions.

    Twenty-one patients with alkylator-resistant plasmacell neoplasms were treated with Peptichemio (PTC) at a dose of 40 mg/m2 for 3 days every 3 weeks or, in the case of persistent leukopenia and/or thrombocytopenia, at the single dose of 70 mg/m2 every 2-3 weeks according to haematological recovery. Seventeen patients, 10 with multiple myeloma and seven with extramedullary plasmacytoma (EMP), were fully evaluable. Six of 17 patients (35%) responded: three of seven EMP patients had a complete remission and 3 of 10 multiple myeloma patients had an objective response greater than 50%. The median duration of response was 8.5 months. An EMP patient obtained a complete response lasting for 16 months. The most frequent toxic effect were phlebosclerosis, occurring in all the patients, and myelosuppression, which was severe in only one case. PTC appears to be an active drug in patients with plasmacell neoplasms even if resistant to alkylating agents.

    Pancreatic neuroendocrine neoplasms (NEN) account for 1-2 % of all pancreatic neoplasms and represent a rare differential diagnosis. While some pancreatic NEN are hormonally active and exhibit endocrine activity associated with characteristic symptoms, the majority are hormonally inactive. Imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) or as combined PET/CT play a crucial role in the initial diagnosis, therapy planning and control. Endoscopic ultrasound (EUS) and multiphase CT represent the reference methods for localization of the primary pancreatic tumor. Particularly in the evaluation of small liver lesions MRI is the method of choice. Somatostatin receptor scintigraphy and somatostatin receptor PET/CT are of particular value for whole body staging and special aspects of further therapy planning. (orig.) [German] Neuroendokrine Neoplasien (NEN) des Pankreas stellen mit einem Anteil von 1-2 % aller pankreatischen Tumoren eine seltene Differenzialdiagnose dar. Ein Teil der Tumoren ist hormonell aktiv und faellt klinisch durch charakteristische Symptome auf, wohingegen der ueberwiegende Anteil hormonell inaktiv ist. Bildgebende Verfahren wie Sonographie, Computertomographie (CT), Magnetresonanztomographie (MRT) und nicht zuletzt Positronenemissionstomographie (PET oder kombiniert als PET/CT) spielen eine zentrale Rolle fuer Erstdiagnose, Therapieplanung und -kontrolle. Die Endosonographie und die multiphasische CT stellen die Referenzmethoden zur Lokalisation des Primaertumors dar. Fuer die Differenzierung insbesondere kleiner Leberlaesionen bietet die MRT die hoechste Aussagekraft. Fuer das Ganzkoerperstaging und bestimmte Aspekte der Therapieplanung lassen sich die Somatostatinrezeptorszintigraphie und v. a. die Somatostatinrezeptor-PET/CT heranziehen. (orig.)

Their impact on survival has not been clearly defined. Methods: This was a retrospective review of clinical data for all consecutive patients with histologically confirmed cancer, with emphasis on single versus multiple primary neoplasms. Second primaries discovered at the workup of the index (first primary were termed simultaneous, if discovered within 6 months of the index primary were called synchronous, and if discovered after 6 months were termed metachronous. Results: Between 2005 and 2012, of 1,873 cancer patients, 322 developed second malignancies; these included two primaries (n=284, and three or more primaries (n=38. Forty-seven patients had synchronous primaries and 275 had metachronous primaries. Patients with multiple primaries were predominantly of Caucasian ancestry (91.0%, with a tendency to develop thrombosis (20.2%, had a strong family history of similar cancer (22.3%, and usually presented with earlier stage 0 through stage II disease (78.9%. When compared with 1,551 patients with a single primary, these figures were 8.9%, 15.6%, 18.3%, and 50.9%, respectively (P≤0.001. Five-year survival rates were higher for metachronous cancers (95% than for synchronous primaries (59% and single primaries (59%. The worst survival rate was for simultaneous concomitant multiple primaries, being a median of 1.9 years. The best survival was for patients with three or more primaries (median 10.9 years and was similar to the expected survival for the age-matched and sex-matched general population (P=0.06991. Conclusion: Patients with multiple primaries are usually of Caucasian ancestry, have less aggressive malignancies, present at earlier stages, frequently have a strong family history of similar cancer, and their cancers tend to have indolent

    To evaluate the changes in prognostic impression and patient management following PET/CT in patients with vulvar and vaginal carcinoma; and to compare PET/CT findings with those of conventional imaging modalities. We summarized prospectively and retrospectively collected data for 50 consecutive patients from our institution that enrolled in the National Oncologic PET Registry and underwent FDG-PET/CT for a suspected or known primary or recurrent vulvar/vaginal cancer. 54/83 (65%) studies included had a diagnosis of vulvar cancer, and the remaining 29/83 (35%), a diagnosis of vaginal cancer. Following FDG-PET/CT, the physician's prognostic impression changed in 51% of cases. A change in patient management, defined as a change to/from a non-interventional strategy (observation or additional imaging), to/from an interventional strategy (biopsy or treatment), was documented in 36% of studies. The electronic records demonstrated that 95% of the management strategies recorded in the physician questionnaires were implemented as planned. MRI and/or CT were performed within one month of the FDG-PET/CT in 20/83 (24%) and 28/83 (34%) cases, respectively. FDG-PET/CT detected nodes suspicious for metastases on 29/83 (35%) studies performed. MRI and CT detected positive nodes on 6 and 11 studies respectively. Distant metastases were identified in 10 cases imaged with FDG-PET and 5 cases that had additional conventional CT imaging. All suspicious lesions seen on CT were positively identified on PET/CT. In 4 cases, an abnormality identified on PET/CT, was not seen on diagnostic CT. FDG-PET/CT may play an important role in the management of vulvar and vaginal carcinoma. Copyright © 2015 Elsevier Inc.

    Cutaneous leiomyomas are firm, round to oval, skin-coloured to brownish papules and nodules that may present as a solitary, few discrete or multiple clustered lesions. Different uncommon patterns of multiple leiomyoma distribution have been noted as bilateral, symmetrical, linear, zosteriform, or dermatomal-like arrangement. One such rare presentation was seen in a 23-year-old patient who presented with zosteriform skin coloured, occasionally painful cutaneous lesions over left shoulder region. Histopathology confirmed the diagnosis of cutaneous leiomyoma. He was symptomatically managed with non-steroidal anti-inflammatory agents and topical capcicum cream. Case is reported here due to rare occurrence of this benign cutaneous neoplasm in an atypical pattern and on uncommon site. (author)

    On the basis of radioisotope studies of 111 children with neoplasms of locomotor system, retroperitoneal space, maxillofacial region and neck, the limits and possibilities of the method of positive radiodiagnostics with short-life radionuclides sup(99M)Tc pertechnetate and 99 Tc pyrophosphate have been analyzed. It is pointed out that sensitivity of the investigation method with sup(99M)Tc pyrophosphate is higher (91.6%) than that of the method with 99 Tc pertechnetate (84.5%). Specificity of the investigation method with 99 Tc p.ertechnetate is higher (71.5%) than that of the method with sup(99M)Tc pyrophosphate (30%). The method of positive radiodiagnostics is characterized by safety, atraumatism, low radiation burdens and possibility of its realization in ambulatory conditions

    A study of 31 patients operated on for rectal neoplasms between September, 1989 and September, 1995 in SantiAug de Cuba was performed. Patients Webre followed-up during this period for the purpose of the study. There was a frank predominance of males and ages between 45 and 64, of the stage II and the groups BI and BII according to Dukes' classification. Most patients received 5-fluoracil, without tumor relapses. The current survival rate of the series was 76 % at the end of the investigation. It is recommended that all patients operated on for this segment be followed-up after the operation; to continue with cytostatic treatment using 5-fluoracil, and to emphasize the importance of the use of tumor markers during the follow-up, in addition to transrectal ultrasound, as well as to make an early diagnosis through mass screening methods

    Histologic characteristics have proven to be very useful for classifying different types of tumors of the pancreas. As a result, the major tumor types in the pancreas have long been classified based on their microscopic appearance. Recent advances in whole exome sequencing, gene expression profiling, and knowledge of tumorigenic pathways have deepened our understanding of the underlying biology of pancreatic neoplasia. These advances have not only confirmed the traditional histologic classification system, but also opened new doors to early diagnosis and targeted treatment. This review discusses the histopathology, genetic and epigenetic alterations and potential treatment targets of the five major malignant pancreatic tumors - pancreatic ductal adenocarcinoma, pancreatic neuroendocrine tumor, solid-pseudopapillary neoplasm, acinar cell carcinoma and pancreatoblastoma.

    Thirty-six cases of primary intracranial neoplasm in children (over 1 year but under 13 years of age) seen at the university medical center between 1951 and 1982 were reviewed because of concern as to the results and after-effects of applied therapy. The overall 5-year actuarial survival rate was 17 %. Several factors of possible prognostic relevance, such as patient's age, intracranial location of the tumor, application or nonapplication of therapy, single or multiple modes of therapy, and extent of surgery, were analyzed. Completeness of surgical removal of the tumor proved to be the only statistically significant factor that correlated with survival. There was only one recorded case of severe learning disability and abnormal neuropsychologic development among the 12 living patients. The influence of patient's age (and technical factors) at the time of irradiation in correlation with the child's subsequent posttreatment functional performance, as reported in the literature, is reviewed.

    Due to modern examination techniques such as multidetector computed tomography and high-field magnetic resonance imaging, the detection rate of renal neoplasms is continually increasing. Even though tumors exceeding 4 cm in diameter rarely metastasize, all renal lesions that are possible neoplasms should be treated. Traditional treatment techniques include radical nephrectomy or nephron-sparing resection, which are increasingly performed laparoscopically. Modern thermal ablation techniques such as hyperthermal techniques like radiofrequency ablation RFA, laser induced thermal ablation LITT, focused ultrasound FUS and microwave therapy MW, as well as hypothermal techniques (cryotherapy) may be a useful treatment option for patients who are unfit for or refuse surgical resection. Cryotherapy is the oldest and best known thermal ablation technique and can be performed laparoscopically or percutaneously. Since subzero temperatures have no antistyptic effect, additional maneuvers must be performed to control bleeding. Percutaneous cryotherapy of renal tumors is a new and interesting method, but experience with it is still limited. Radiofrequency ablation is the most frequently used method. Modern probe design allows volumes between 2 and 5 cm in diameter to be ablated. Due to hyperthermal tract ablation, the procedure is deemed to be safe and has a low complication rate. Although there are no randomized comparative studies to open resection, the preliminary results for renal RFA are promising and show RFA to be superior to other thermal ablation techniques. Clinical success rates are over 90% for both, cryo- and radiofrequency ablation. Whereas laser induced thermal therapy is established in hepatic ablation, experience is minimal with respect to renal application. For lesions of more than 2 cm in diameter, additional cooling catheters are required. MR thermometry offers temperature control during ablation. Microwave ablation is characterized by small ablation volumes

    Lichen sclerosus (LS) of the vulva can profoundly affect sexual interaction because of painful fissures and narrowing of the vaginal introitus. Successful surgical treatment is usually defined as restoration of (pain-free) penetrative sexual activity. To evaluate the impact of surgery on (dyadic) sexual functioning and pleasure and psychological well-being. Nineteen women with anogenital LS participated in audiotaped, qualitative, individual interviews after surgery to re-enable sexual intercourse. Physical, sexual, and psychological experiences were analyzed using the constant comparative method. Vulvar surgery resulted in a decrease of sexual pain in 13 of 19 patients (68%). Of these 13 patients, 4 were completely free of pain and the other 9 patients expressed a shift from preoperative sexual pain to postoperative sexual discomfort. These women reported improved sexual functioning, increased sexual activity and intimacy with the partner, and reinstated feelings of being an adequate woman and sexual partner. In 1 of the 19 patients (5%), surgery did not result in decreased sexual pain, yet she continued to have intercourse. Five of the 19 patients (26%) stopped having intercourse because of pain; one woman had secondary vaginismus and another woman, in retrospect, had premorbid generalized unprovoked vulvodynia. Four of these women were unable to communicate with their partner about sexual matters and to change their sexual repertoire (satisfactorily) once they had ceased intercourse (attempts). Eighteen women (95%) reported a decrease of LS symptoms in daily life. Vulvar surgery seems an effective treatment for most women with LS who experience sexual pain owing to anatomic or epithelial changes and who wish to resume intercourse. To assess whether women might benefit from such surgery and/or whether (additional) sexual counseling is indicated, preoperative sexological couple-based consultation is needed. This consultation should exclude comorbid vaginismus and

    To prospectively evaluate the value of CT or MRI (CT/MRI) and PET in the management of vulvar malignancies. Abdominal and pelvic CT/MRI and whole-body 18 F-FDG (fluorodeoxyglucose) PET or PET/CT (collectively designated PET hereafter) were performed. Lesion status was determined by the pathological findings or clinical follow-up. The diagnostic efficacy was evaluated by receiver operating characteristic (ROC) curve analysis. The clinical impact of PET was determined on a per scan basis. Twenty-three patients were enrolled, and 38 PET examinations were performed. CT/MRI and PET studies were used for primary staging (n = 17), monitoring the response (n = 7) and restaging after recurrence (n = 14). In primary staging, there was no significant difference between CT/MRI and PET in detecting metastatic inguinal lymph nodes (ILN). CT/MRI was significantly more efficacious than PET in detecting pelvic lymph node (PLN) or distant metastasis (p = 0.007 by ROC per patient basis). PET findings resulted in two positive impacts and one negative impact for both primary staging and restaging. False-positive PLN or distant metastasis PET findings are not uncommon, and hence should be interpreted with caution. PET can be supportive when metastatic ILN/PLN or distant metastasis is suspected on CT/MRI. (orig.)

  14. Vulvar Asymmetry Due to Silicone Migration and Granulomatous Immune Response Following Injection for Buttock Augmentation.

    A 34-year-old woman was referred to the authors' dermatology clinic for evaluation of right labial swelling and dyspareunia. Her symptoms began after receiving a liquid silicone injection into the buttocks at a cosmetic plastic surgery clinic that was operating illegally by an unlicensed provider. A single prior debulking surgery had produced only temporary relief of symptoms, and the swelling returned. Work-up including magnetic resonance imaging and skin biopsy revealed migration of the injected silicone from her buttock to the subcutaneous tissue of the right labia majora, with an associated granulomatous immune response to the silicone. To the authors' knowledge, the extent of contiguous soft tissue involvement shown in this case has not yet been reported in the medical literature, nor has the finding of migration from the buttocks to the vulvar tissues to produce such dramatic asymmetry. Treatment with intralesional steroids and minocycline was initiated with improvement noted at one-month follow-up. Large volume and adulterated silicone injections are associated with a host of complications, including silicone migration and granuloma formation. No consensus for treatment exists, but attempted therapies have included surgery, local steroid injections, systemic steroids, tetracycline antibiotics, and other immune modulators. Treatment must be tailored to the individual case, considering the patient's preferences and medical history.

    The aim of the study was to investigate the prevalence of vulvar vestibulitis syndrome (VVS) in a sample of women suffering from lifelong vaginismus (N=91). Lifelong vaginismus is defined as "having a history of never having been able to experience penile entry of the vagina". The results with respect to VVS are compared with the results of women who are suffering from pain during intercourse (superficial dyspareunia) (N=84). Both patients groups were recruited from two treatment outcome studies. Using a standard physical examination, erythema was found in 77%, pain "on touch" in 69% and erythema and pain on the same location was seen in 56% of the patients with lifelong vaginismus. Furthermore, it was found that erythema (94%), pain (98%) and erythema and pain on the same location (92%) were more frequently found in patients with dyspareunia compared to women with lifelong vaginismus. It is concluded that pain is an integral part of the experiences in the majority of women with lifelong vaginismus.

    Objective The primary aim of this study is to describe the prevalence of select oncogenic viruses within vulvar squamous cell carcinoma (VSCC) and their association with Human Immunodeficiency Virus (HIV) status in women in Botswana, where the national HIV prevalence is the third highest in the world. Methods/materials A cross-sectional study of biopsy-confirmed VSCC specimens and corresponding clinical data was conducted in Gaborone, Botswana. Polymerase Chain Reaction (PCR) and Immunohistochemistry (IHC) viral testing were done for Epstein-Barr Virus (EBV), Human Papilloma Virus (HPV) strains, and Kaposi's Sarcoma Herpesvirus (KSHV), and PCR viral testing alone was done for John Cunningham Virus (JCV). Results HPV prevalence by PCR was 100% (39/39 35/35) among tested samples. HPV16 was the most prevalent HPV strain (82.9% by PCR, 94.7% by either PCR or IHC). KSHV prevalence by PCR had a significant association with HIV status (p = 0.013), but not by IHC (p = 0.650). Conclusions The high burden of HPV, specifically HPV16, in VSCC in Botswana suggests a distinct HPV profile that differs from other studied populations, which provides increased motivation for HPV vaccination efforts. Oncogenic viruses KSHV and EBV were also more prevalent in our study population though their potential role in VSCC pathology is unclear. PMID:24651632

    Eponyms serve the purpose of honoring individuals who have made important observations and discoveries. As with other fields of medicine, eponyms are frequently encountered in radiology, particularly in chest radiology. However, inappropriate use of an eponym may lead to potentially dangerous miscommunication. Moreover, an eponym may honor the incorrect person or a person who falls into disrepute. Despite their limitations, eponyms are still widespread in medical literature. Furthermore, in some circumstances, more than one individual may have contributed to the description or discovery of a particular anatomical structure or disease, whereas in others, an eponym may have been incorrectly applied initially and propagated for years in medical literature. Nevertheless, radiologic eponyms are a means of honoring those who have made lasting contributions to the field of radiology, and familiarity with these eponyms is critical for proper reporting and accurate communication. In addition, the acquisition of some historical knowledge about those whose names are associated with various structures or pathologic conditions conveys a sense of humanity in the field of medicine. In this article, the first of a multipart series, the authors discuss a number of chest radiology eponyms as they relate to neoplasms, including relevant clinical and imaging features, as well biographic information of the respective eponym׳s namesake.

    We have previously defined a new syndrome "Minimally-aggressive gestational trophoblastic neoplasms" in which choriocarcinoma or persistent hydatidiform mole has a minimal growth rate and becomes chemorefractory. Previously we described a new treatment protocol, waiting for hCG rise to >3000 mIU/ml and disease becomes more advanced, then using combination chemotherapy. Initially we found this treatment successful in 8 of 8 cases, here we find this protocol appropriate in a further 16 cases. Initially we used hyperglycosylated hCG, a limited availability test, to identify this syndrome. Here we propose also using hCG doubling rate to detect this syndrome. Minimally aggressive gestational trophoblastic disease can be detected by chemotherapy resistance or low hyperglycosylated hCG, disease by hyperglycosylated hCG and by hCG doubling test. All were recommended to hold off further chemotherapy until hCG >3000mIU/ml. One case died prior to the start of the study, one case withdrew because of a lung nodule and one withdrew refusing the suggested combination chemotherapy. The remaining 16 women were all successfully treated. A total of 8 plus 16 or 24 of 24 women were successfully treated using the proposed protocol, holding back on chemotherapy until hCG >3000mIU/ml.

  19. Mechanisms of mutations in myeloproliferative neoplasms.

    Levine, Ross L

    2009-12-01

    In recent years, a series of studies have provided genetic insight into the pathogenesis of myeloproliferative neoplasms (MPNs). It is now known that JAK2V617F mutations are present in 90% of patients with polycythaemia vera (PV), 60% of patients with essential thrombocytosis (ET) and 50% of patients with myelofibrosis (MF). Despite the high prevalence of JAK2V617F mutations in these three myeloid malignancies, several questions remain. For example, how does one mutation contribute to the pathogenesis of three clinically distinct diseases, and how do some patients develop these diseases in the absence of a JAK2V617F mutation? Single nucleotide polymorphisms at various loci and somatic mutations, such as those in MPLW515L/K, TET2 and in exon 12 of JAK2, may also contribute to the pathogenesis of these MPNs. There are likely additional germline and somatic genetic factors important to the MPN phenotype. Additional studies of large MPN and control cohorts with new techniques will help identify these factors.

    Full Text Available Abstract Introduction Oncocytic neoplasms occur in several organs and are most commonly found in the thyroid, kidneys and salivary glands. Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually non-functioning. Case presentation We report the case of an adrenocortical oncocytic neoplasm with uncertain malignant potential in a 31-year-old man with Cushing's syndrome. The patient had been operated on following diagnosis of a 7 cm adrenal mass. Following surgery, the Cushing's syndrome resolved. The patient is still alive with no metastases one year after the surgery. Conclusion Adrenocortical oncocytic neoplasms must be considered in the differential diagnosis of both functioning and non-functioning adrenal masses.

    It is shown that application of ultrasonography and computerized tomography in examining the upper part of abdomen in patients with stomach neoplasm permits to judge on metastases into the liver. Application of invasive methods of examination is indicated only in case of indefinite data of ultrasonography and computerized tomography. It is shown that application of invasive methods isn't advisable in patients with stomach neoplasm to which palliative operations are indicated. 4 refs

    Full Text Available Abstract Introduction: In cancer patients, the reduced food intake causes weight loss and promotes protein-calorie malnutrition. This results in loss of lean body mass, which affects both skeletal muscles and respiratory muscles. Objective: Evaluate and compare the respiratory muscle strength of patients with esophageal and stomach neoplasia during the preoperative period. Methods: This is a cross-sectional study carried out with 24 patients of both genders hospitalized in a teaching hospital. They underwent a physical therapy evaluation composed of anthropometric data and measurement of respiratory muscle strength through manovacuometry. Paired and unpaired t-tests were used to compare the values obtained with the predicted equations. Results: Regarding the disease prevalence, 66.66%(16 of the individuals had stomach neoplasm and 33.33%(8 esophageal neoplasm. Of the patients with esophageal neoplasm, 100% were men with a mean age of 63 ± 9.16 years. Of those with stomach neoplasm, 68.75% were men with a mean age of 69.36 ± 10.92 years. Female patients with stomach neoplasm had significantly higher BMI (p = 0.01 than male patients, and they were classified as overweight. Both neoplasms had significantly lower real values (p ≤ 0.05 than predicted values at the maximal expiratory pressure. Conclusion: Patients with esophageal and stomach neoplasms in the preoperative period present reduction in the expiratory muscle strength. There were no statistically significant differences, when we compared the maximum respiratory pressures between the two types of neoplasms investigated.

    Tattooing, which involves the placement of ink into the skin, is an ancient decorative technique that has remained popular in modern society. Tattoos have long been known to cause cutaneous reactions, which include the emergence of neoplasms such as keratoacanthoma (KA) and squamous cell carcinoma (SCC) in tattooed areas of the skin. We review the clinical presentations, histology and treatment options for squamous neoplasms, primarily KA and SCC, arising in tattoos. © 2017 British Association of Dermatologists.

    Myeloproliferative neoplasm (MPN) variants are defined as relatively uncommon myeloid neoplasms which do not meet the criteria for either classical MPN or myelodysplastic syndrome. Due to the lack of specific markers, it has been challenging to accurately diagnose these malignant diseases. Recent studies have revealed new genetic abnormalities in MPN variants. These research advances are anticipated to open new approaches to not only achieving accurate diagnosis but also novel therapeutic options for these diseases.

  10. Origin of B-Cell Neoplasms in Autoimmune Disease.

    Directory of Open Access Journals (Sweden)

    Full Text Available Autoimmune diseases (ADs are associated with a number of B-cell neoplasms but the associations are selective in regard to the type of neoplasm and the conferred risks are variable. So far no mechanistic bases for these differential associations have been demonstrated. We speculate that developmental origin of B-cells might propose a mechanistic rationale for their carcinogenic response to autoimmune stimuli and tested the hypothesis on our previous studies on the risks of B-cell neoplasms after any of 33 ADs. We found that predominantly germinal center (GC-derived B-cells showed multiple associations with ADs: diffuse large B cell lymphoma associated with 15 ADs, follicular lymphoma with 7 ADs and Hodgkin lymphoma with 11 ADs. Notably, these neoplasms shared significant associations with 5 ADs (immune thrombocytopenic purpura, polymyositis/dermatomyositis, rheumatoid arthritis, Sjogren syndrome and systemic lupus erythematosis. By contrast, primarily non-GC neoplasms, acute lymphocytic leukemia, chronic lymphocytic leukemia and myeloma associated with 2 ADs only and mantle cell lymphoma with 1 AD. None of the neoplasms shared associated ADs. These data may suggest that autoimmune stimulation critically interferes with the rapid cell division, somatic hypermutation, class switch recombination and immunological selection of maturing B-cell in the GC and delivers damage contributing to transformation.

    Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults. Neuroblastoma, rhabdomyosarcoma, benign teratoma and lymphoma are the common retroperitoneal neoplasms. In this review, the clinical and CT futures of common retroperitoneal neoplasms in children are described. Coarse, amorphous, and mottled calcification are very common in neuroblastoma. Paraganglioma tends to show marked and early enhancement and may present with clinical symptoms associated with the excess catecholamine. Sarcomas are often very large and have heterogeneous appearance. Imaging cannot be reliably used to identify the type of retroperitoneal sarcomas due to overlapped radiographic features. In children, lipoblastoma is the most common lipomatous tumor in the retroperitoneum. The percentage of visible fat in tumor varies depending on the cellular composition of the lesion. The CT characteristics of teratoma are quite variable, which may be cystic, solid, on a combination of both. Typically teratoma appears as a large complex mass containing fluid, fat, fat-fluid level, and calcifications. Lymphoma is often homogeneous on both enhanced and unenhanced CT scans. Necrosis and calcification are rare on CT. In conclusion, making a final histological diagnosis of retroperitoneal tumor base on CT features is not often possible; however, CT can help to develop a differential diagnosis and determine the size and extent of the retroperitoneal neoplasms.

    Myeloid neoplasms are classified into five major categories. These patients may develop splenomegaly and require splenectomy to alleviate mechanical symptoms, to ameliorate transfusion-dependent cytopenias, or to enhance stem cell transplantation. The objective of this study was to determine which clinical variables significantly impacted morbidity, mortality, and survival in patients with myeloid neoplasms undergoing splenectomy, and to determine if operative outcomes have improved over time. The records of all patients with myeloid neoplasms undergoing splenectomy from 1993 to 2010 were retrospectively reviewed. Eighty-nine patients (n = 89) underwent splenectomy for myeloid neoplasms. Over half of patients who had symptoms preoperatively had resolution of their symptoms post-splenectomy. The morbidity rate was 38%, with the most common complications being bleeding (14%) or infection (20%). Thirty-day mortality rate was 18% and median survival after splenectomy was 278 days. Decreased survival was associated with a diagnosis of myelodysplastic syndrome/myeloproliferative neoplasm, anemia, abnormal white blood cell count, and hypoalbuminemia. Patients who underwent stem cell transplantation did not show an increased risk for morbidity or mortality. Patients with myeloid neoplasms have a poor prognosis after splenectomy and the decision to operate is a difficult one, associated with high morbidity and mortality. © 2014 Wiley Periodicals, Inc.

    The literature on genital and pelvic pain has largely focused on heterosexual women. An online study examined characteristics of vulvar pain in 839 lesbian, bisexual, and heterosexual women 18-45 years of age and investigated associations between relationship qualities such as love and communication with participants' perceptions of pain's influence on relationships. Characteristics of vulvar pain were similar across groups. Groups differed in how they perceived pain to impact their relationships, such that better communication for same-sex couples and more love for mixed-sex couples was associated with the perception of their pain as having less of an effect on their relationship functioning.

    A recent pathological and epidemiological study on females with ovarian neoplasms among the Radiation Effects Research Foundation (RERF) Life Span Study (LSS) Extended Sample ascertained 194 malignant and 106 benign ovarian tumor cases which had occurred during the period 1950 - 80. Of the 194 cases of ovarian cancer, 128 (66 %) were reviewed microscopically and the age-adjusted incidence of ovarian cancer revealed a statistically significant linear increase with increasing exposure dose, both in microscopically reviewed and in all cases. The radiation-related excess of ovarian cancer appeared to be highest in women less than 20 years of age when exposed, with these women having the longest latent period for tumor development, compared to the older age groups. The histological distribution of cancer types among exposed individuals appeared not very different from that seen in the general population. The analysis of 106 autopsy subjects with benign ovarian tumors, of which 89 were reviewed microscopically, depicted a trend of increasing radiation-related tumor excess with increasing exposure dose among exposed cases, though the trend is not statistically significant when observation was limited to microscopically reviewed subjects. The histological distribution of benign tumor types among exposed cases appeared not very different from that seen in the general population. The findings are consistent with a hypothesis that radiation-injured ovaries in association with secondary excess of gonadotrophic hormones are important causative factors in the development of ovarian tumors, which has been suggested by experimental findings concerning the induction of ovarian tumors by ionizing radiation and by a recent analysis of breast carcinogenesis in exposed females of Hiroshima and Nagasaki.

  15. Secondary malignant neoplasms in testicular cancer survivors.

    Curreri, Stephanie A; Fung, Chunkit; Beard, Clair J

    2015-09-01

    Testicular cancer is the most common cancer among men aged 15 to 40 years, and the incidence of testicular cancer is steadily increasing. Despite successful treatment outcomes and the rate of survival at 5 to 10 years being 95%, survivors can experience late effects of both their cancer and the treatment they received, including secondary malignant neoplasms (SMNs). We discuss the development of non-germ cell SMNs that develop after diagnosis and treatment of testicular cancer and their effect on mortality. Patients diagnosed with testicular cancer frequently choose postoperative surveillance if they are diagnosed with clinical stage I disease. These patients may experience an increased risk for developing SMNs following radiation exposure from diagnostic imaging. Similarly, radiotherapy for testicular cancer is associated with increased risks of developing both solid tumors and leukemia. Studies have reported that patients exposed to higher doses of radiation have an increased risk of developing SMNs when compared with patients who received lower doses of radiation. Patients treated with chemotherapy also experience an increased risk of developing SMNs following testicular cancer, though the risk following chemotherapy and radiation therapy combined is not well described. A large population-based study concluded that the rate ratios for both cancer-specific and all-cause mortality for SMNs among testicular cancer survivors were not significantly different from those of matched first cancers. Although it is known that patients who receive adjuvant chemotherapy or radiotherapy or who undergo routine diagnostic or follow-up imaging for a primary testicular cancer are at an increased risk for developing SMNs, the extent of this risk is largely unknown. It is critically important that research be conducted to determine this risk and its contributing factors as accurately as possible. Copyright © 2015 Elsevier Inc. All rights reserved.

    Epstein-Barr virus (EBV) infection can rarely present as painful genital ulcers, mostly in young female adolescents. Typically diagnosed by clinical findings, EBV vulvar ulceration (EBVVU) is rarely biopsied. Herein, the authors report the histopathology in 8 biopsies from 7 EBVVU patients, all serologically confirmed for acute (4/7) or reactivated-chronic (3/7) EBV infection. The 7 women all presented with 1 or more painful, punched-out vulvar ulcers. Only patients with acute EBV infection showed other clinical findings: fever and/or atypical lymphocytosis affected 75% (3/4); lymphadenopathy in 50%; and malaise/fatigue, dysuria and/or hepatomegaly in 25%. All reactivated-chronic EBVVU had a solitary ulcer, and 2 had history of a similar episode of vulvar ulceration (aphthosis). Histopathologically, lymphocytic arteritis was identified in 88% (7/8); a submucosal scar was found in the eighth specimen. Other histopathologies included venulitis (62%), endarteritis obliterans (38%), thrombosis (25%), neutrophilic sebaceous adenitis (25%), and mucosal lymphoid hyperplasia (12%). Dense angiocentric CD3 CD4 T-cell lymphocyte-predominant infiltrates were found, regionally or diffusely. In 2 specimens, neutrophils compromised half of the infiltrate. Minor components of CD8, CD20, and CD30 lymphocytes, CD123 plasmacytoid monocytes, CD68 macrophages, and plasma cells were present. Small-vessel endothelium and smooth muscle adjacent to the ulcers faintly expressed cytoplasmic EBV latent membrane protein-1 (LMP1). In situ hybridization for early EBV mRNA (EBER) identified rare solitary or scattered clustered positive lymphocytes in 38%. Polymerase chain reaction for EBV DNA was positive in one EBER positive biopsy. EBV infection has been documented in muscular vessel vasculitis. Based on the aforementioned, EBVVU appears to be the consequence of localized lymphocytic arteritis.

    Purpose: The objective of our study was to demonstrate differences in relapse rates, total survival times, and complication rates between inguinofemoral radiation and its absence in cases of invasive vulvar carcinoma without lymph node involvement (FIGO Stages T1, N0-1). Methods and Materials: From 1974 to 1990, 135 patients with invasive vulvar carcinoma in Stage T1 without clinical evidence of inguinal lymph node involvement underwent simple vulvectomy performed by hot-knife resection without lymphadenectomy. Although 65 patients (Group 1) received postoperative inguinofemoral radiation therapy, 70 patients (Group 2) did not, and none received local vulva irradiation. Results: The 5-year survival rates were 93.7% in Group 1 and 91.4% in Group 2 (p = NS). Although clitoris involvement was significantly more prevalent in the irradiation group (p = 0.04), inguinal relapse was found less frequently in Group 1 (4.6% or 3 out of 65 patients) than in group 2 (10% or 7 out of 70 patients) (p = 0.32). The complication rates were, 7.7% in Group 1 and 2.9% in Group 2, 2.7% for vaginal stenosis (two patients in each group), 1.5% for inguinal pain (one patient in Group 1), 1.5% for recto vaginal fistula (one patient in Group 1), 1.5% for vulvar infection (one patient in Group 1). Conclusion: No statistically significant differences in the relapse rates and survival times were found. Risk factors were equally distributed in both study groups except for clitoris involvement. The 5-year survival rates in both groups were similar to those reported in the literature for radical vulvectomy and inguinal lymph-node dissection (83-96%). Morbidity in our study was low. Although our data showed similar results in both groups, we are not recommending at this time to omit groin radiation in general, but it may be justified in low-risk cases

    This study evaluates the frequency and type of TP53 gene mutations and HPV status in 72 consecutively diagnosed primary invasive vulvar squamous cell carcinomas (SCC) during the past 5years. DNA of formalin-fixed and paraffin embedded tumour tissue was analysed for 32 HPV subtypes and the full coding sequence of the TP53 gene, and correlated with results of p53 immunohistochemistry. 13/72 (18%) cancers were HPV-induced squamous cell carcinomas, of which 1/13 (8%) carcinoma harboured a somatic TP53 mutation. Among the 59/72 (82%) HPV-negative cancers, 59/72 (82%) SCC were HPV-negative with wild-type gene in 14/59 (24%) SCC and somatic TP53 mutations in 45/59 (76%) SCC. 28/45 (62%) SCC carried one (n=20) or two (n=8) missense mutations. 11/45 (24%) carcinomas showed a single disruptive mutation (3× frame shift, 7× stop codon, 1× deletion), 3/45 SCC a splice site mutation. 3/45 (7%) carcinomas had 2 or 3 different mutations. 18 different "hot spot" mutations were observed in 22/45 cancers (49%; 5× R273, 3× R282; 2× each Y220, R278, R248). Immunohistochemical p53 over expression was identified in most SCC with missense mutations, but not in SCC with disruptive TP53 mutations or TP53 wild-type. 14/45 (31%) patients with TP53 mutated SCC died of disease within 12months (range 2-24months) versus 0/13 patients with HPV-induced carcinomas and 0/14 patients with HPV-negative, TP53 wild-type carcinomas. 80% of primary invasive vulvar SCC were HPV-negative carcinomas with a high frequency of disruptive mutations and "hot spot" TP53 gene mutations, which have been linked to chemo- and radioresistance. The death rate of patients with p53 mutated vulvar cancers was 31%. Immunohistochemical p53 over expression could not reliably identify SCC with TP53 gene mutation. Pharmacological therapies targeting mutant p53 will be promising strategies for personalized therapy in patients with TP53 mutated vulvar cancers. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available Objective: In patients receiving bone marrow transplantation (BMT, their mucosa becomes altered and sclerotic changes in the female external genital organs occur. Although a few studies have specifically addressed vulvar and vaginal graft versus host disease (VVGvHD and its repercussions on the sexual health and quality of life of patients, VVGvHD can be overlooked by health practitioners. The objective of the study is to describe the initiation of a health care clinic specializing in VVGvHD in a general tertiary hospital. Methods: A VVGvHD clinic was founded as a part of BMT daycare in a joint initiative of the nursing staff and the medical director of the department and a gynecologist specializing in vulva and vaginal disease. Patients were assessed for vulvovaginal symptoms, such as dryness, burning, itching, pain to touch, pain during intercourse, and dysuria. These patients might be subsequently referred to the VVGvHD clinic according to their needs assessed by daycare nurses. Treatment guidelines were developed by the specialist gynecologist. Results: A total of 81 women aged 2–66 years (median age = 38 years visited the clinic from 2009 to 2015. Of these women, 70 received an allogeneic transplant and 11 underwent autologous transplantation before consultation in our clinic. VVGvHD was detected in 54% of the patients. Conclusions: The VVGvHD clinic was developed to fulfill the specific needs of female patients who underwent BMT. The pioneer clinic was founded as a joint effort of the multidisciplinary team. Evidence supporting the optimum treatment for this condition is insufficient. This was the main reason for performing this study to explore the clinic that was newly based in Israel. VVGvHD may be a fluctuating condition with frequent deterioration and improvement. Therefore, regular clinical examinations are necessary.

    Full Text Available La Neoplasia Intraepitelial Vulvar (NIV constituye lesiones potencialmente premalignas del epitelio escamoso de la vulva con diversos grados de diferenciación celular y maduración. En el aspecto histológico son hiperplasia de las células basales y parabasales, además tienen características genéticas morfológicas y metabólicas similares a las células cancerosas. Son etapas previas a la enfermedad. Generalmente las NIV se diagnostican como lesiones de alto grado (NIV I, II y III o carcinoma in situ. Alrededor del 5% progresan a la malignidad. Técnicamente puede ser un diagnóstico fácil, pero en la práctica no resulta así, siendo la vulvoscopia la principal arma para su diagnóstico. Estudios realizados en los últimos años señalan que aumenta cada vez más en mujeres más jóvenes, en pacientes con infección por HPV, en pacientes con neoplasia cervical intraepitelial o en cáncer en otras localizaciones del extracto genital inferior. Para tomar una decisión terapéutica hay que tener en cuenta: la edad de la paciente, la localización de las lesiones (áreas pilosas y no pilosas o descartar siempre un cáncer invasor y no invasor. Los tratamientos de lección pueden ser, extirpación local, vulvahectomía cutania parcial o total, destrucción con crioterapia o láser y técnicas combinadas de escisión o ablación. La conducta expectante valorando algunas características es la tendencia actual.

    To evaluate the imaging findings of abdominal extraosseous plasma cell neoplasm. From April 2000 to January 2005, eight patients (four men, four women; mean age, 50.6 years) with pathologically proved, extraosseous plasma cell neoplasm involving the abdominal organs were included in this study. The diagnoses were based on consensus agreement between two radiologists who retrospectively reviewed CT, ultrasonography, and enteroclysis findings. We evaluated the findings by focusing on the location, size, margin, and enhancement pattern of the lesion, and lymphadenopathy on each image. There were multiple myeloma in four patients and extramedullary plasmacytoma in the remaining four. Involved abdominal organs were the liver (n = 4), spleen (n 4), lymph node (n = 3), stomach (n = 1), small bowel (n = 1), and colon (n 1). The hepatic involvement of plasma cell neoplasm presented as a homogeneous, well-defined, solitary mass (n = 1), multiple nodules (n = 1), and hepatomegaly (n = 2). Its involvement of the spleen and lymph node appeared as splenomegaly and lymphadenopathy, respectively. Its involvement of the gastrointestinal tract including the stomach, small bowel, and colon, presented as a homogeneous, diffuse wall thickening or mass in the gastrointestinal tract. Abdominal extraosseous plasma cell neoplasm involves occasionally the liver, spleen, and lymph node, and rarely the gastrointestinal tract. When we encounter a well-defined, homogeneous lesion of the abdominal organs in patients diagnosed or suspected as having plasma cell neoplasm, we should consider its involvement of the abdominal organs

    Full Text Available Several studies have shown that a woman’s vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on pads affixed to the axilla and on panty protectors both worn the entire night before experiments. Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60 and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol. Periovulatory axilla and vulva scents accounted for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant.

    To know the three questions about multiple primary cancers: 1) what are the characteristics of persons having multiple primary cancer? 2) Dose presence of a single primary concern after the susceptibility to multiple primary cancers? 3) Dose the location of one multiple primary cancer influence the site of others?, we analysed 121 cases of multiple primary malignant neoplasms registered in Seoul National University Hospital during 8years from July 1978 to August 1986. Of 121 cases, double primary malignant neoplasms were 119 cases and triple were 2 cases. The incidence of multiple primary malignant neoplasms was 0.7%. The metachronous tumor(> 6 months) was found in 70 cases and the median time between the first and the second was 32 months. The most commonly associated tumors were stomach and primary liver carcinoma. Cervix and Lung cancer, Stomach and Rectal cancer, Stomach and Esophagus cancer were also commonly associated

    2012-01-01

    Full Text Available Cystic neoplasms of the pancreas are increasingly recognized due to the frequent use of abdominal imaging. It is reported that up to 20% of abdominal cross-sectional scans identify incidental asymptomatic pancreatic cysts. Proper characterization of pancreatic cystic neoplasms is important not only to recognize premalignant lesions that will require surgical resection, but also to allow nonoperative management of many cystic lesions that will not require resection with its inherent morbidity. Though reliable biomarkers are lacking, a wide spectrum of diagnostic modalities are available to evaluate pancreatic cystic neoplasms, including radiologic, endoscopic, laboratory, and pathologic analysis. An interdisciplinary approach to management of these lesions which incorporates recent, specialty-specific advances in the medical literature is herein suggested.

    The 1957-1958 incidence of neoplasms among the survivors of the Hiroshima A-bomb, varies directly with radiation dose insofar as it may be inferred from distance from the hypocenter at exposure. The incidence of all malignant neoplasms among the survivors who were within 1000 meters is more than 4 times that of the non-exposed population. The incidence of benign neoplasms among the survivors exposed within 1500 meters is also significantly higher than that among the non-exposed. For survivors under 1500 meters significant differences are seen between the numbers of observed cancers of the lung, stomach, uterus and ovary and the expected cases calculated from the age-specific rates of the non-exposed portion of the Hiroshima population. The increased incidence among survivors within 1500 meters is not related to sex or age. 18 references, 2 figures, 14 tables.

    Digestive system neoplasms are the leading causes of cancer-related death all over the world. Solute carrier (SLC) superfamily is composed of a series of transporters that are ubiquitously expressed in organs and tissues of digestive systems and mediate specific uptake of small molecule substrates in facilitative manner. Given the important role of SLC proteins in maintaining normal functions of digestive system, dysregulation of these protein in digestive system neoplasms may deliver biological and clinical significance that deserves systemic studies. In this review, we critically summarized the recent advances in understanding the role of SLC proteins in digestive system neoplasms. We highlighted that several SLC subfamilies, including metal ion transporters, transporters of glucose and other sugars, transporters of urea, neurotransmitters and biogenic amines, ammonium and choline, inorganic cation/anion transporters, transporters of nucleotide, amino acid and oligopeptide organic anion transporters, transporters of vitamins and cofactors and mitochondrial carrier, may play important roles in mediating the initiation, progression, metastasis, and chemoresistance of digestive system neoplasms. Proteins in these SLC subfamilies may also have diagnostic and prognostic values to particular cancer types. Differential expression of SLC proteins in tumors of digestive system was analyzed by extracting data from human cancer database, which revealed that the roles of SLC proteins may either be dependent on the substrates they transport or be tissue specific. In addition, small molecule modulators that pharmacologically regulate the functions of SLC proteins were discussed for their possible application in the treatment of digestive system neoplasms. This review highlighted the potential of SLC family proteins as drug target for the treatment of digestive system neoplasms.

    The development of lung carcinoma in uranium miners is discussed. In spite of the decreasing radiation risks in mines, the absolute number of neoplasms has increased since the 1960's; this is due to the increasing number of miners, improved diagnostic methods and the aging of miners who thus enter higher age groups where a higher incidence of neoplasms can be expected. The probabilistic method was shown to be of help in deciding whether individual cases of lung carcinoma should be considered an occupational disease; new possible improvements of the method are suggested.

    The meninges composed of the dura, the arachnoid and the pia are significant sites of blood-brain barrier. Physical disruption of the integrity of the meninges from a variety of causes including surgery results in various patterns of meningeal enhancement on contrast enhanced MR images. It is important to distinguish normal reactive or benign postoperative enhancement from more serious leptomeningeal metastasis or infection, particularly in children with intracranial neoplasms. We present various patterns of meningeal enhancement on MRI in children following surgery for brain neoplasms. (author)

    Full Text Available Castleman’s disease is a rare nonclonal proliferative disorder of the lymph nodes with an unknown etiology. Common locations of Castleman’s disease are mediastinum, neck, axilla, and abdomen. Castleman’s disease of a peripancreatic location masquerading as pancreatic neoplasm is an even rarer entity. On search of published data, we came across about 17 cases published on peripancreatic Castleman’s disease until now. Here we are reporting a case of retropancreatic Castleman's disease masquerading as retroperitoneal neoplasm in a 46-year-old male patient.

    Most human papillomavirus (HPV)-associated vulvar squamous cell carcinomas (VSCCs) originate from high-grade squamous intraepithelial lesions, also named usual type vulvar intraepithelial neoplasia. However, growing evidence suggests that morphologic studies have limitations in predicting HPV status in vulvar lesions. We aimed to evaluate adjacent intraepithelial lesions in a series of DNA HPV-positive VSCCs, focusing on unusual histologic patterns mimicking differentiated vulvar intraepithelial neoplasia (dVIN) or lichen sclerosus (LS). We identified 326 DNA HPV-positive VSCC with at least 1 cm of skin adjacent to the invasive tumor and analyzed HPV typing, HPV E6*I mRNA, and p16 immunohistochemistry in all cases. A careful histologic evaluation was conducted. A conclusive association with HPV was based on a positive p16 or HPV E6*I mRNA result or both in addition to the HPV DNA, whereas cases negative for both markers were classified as nonconclusively associated with HPV. One hundred twenty-one tumors (37.1%) had normal adjacent skin, 191 (58.6%) had only high-grade squamous intraepithelial lesions, also named usual type vulvar intraepithelial neoplasia, and unusual intraepithelial lesions were identified in 14 (4.3%) tumors. Seven cases showed dVIN-like features, 5 showed adjacent LS-like lesion, and in 2 cases dVIN-like and LS-like lesions were identified simultaneously. Six of them were conclusively associated with HPV (3 dVIN-like, 2 LS-like, 1 with combined dVIN/LS-like features). All 6 tumors were associated with HPV16 and were positive for both p16 and HPV mRNA, and p16 was also positive in the dVIN-like and LS-like lesions. In summary, a small subset of VSCCs conclusively associated with HPV may arise on intraepithelial lesions, mimicking precursors of HPV-independent VSCC.

Se presenta el caso de una mujer de 59 años, que en el año 2000 se le diagnostica carcinoma epidermoide del clítoris, en 2004 se vuelve a intervenir por recidiva tumoral, y en 2009 acude a nuestra consulta nuevamente y es cuando se decide realizarle vulvectomía y resección de vagina y todo el sistema ginecológico. Concluyó la intervención con una talla vesical extraperitoneal. El tumor se extiende hasta la porción inicial de la vagina y uretra. Se trata de un tumor maligno, bien diferenciado, que se ha comportado en una forma no habitual, con recidivas locales, cuando en apariencia el tumor había sido resecado en toda su extensión, y en esta última oportunidad, a pesar de ser un estadio avanzado, no hemos encontrado metástasis ni multicentricidad del tumor. La evolución posoperatoria fue sin complicaciones y se dio de alta al quinto día.The vulvar tumors are not uncommon among the different types of cancer involving females, but neither are the more frequent ones. This is the case of a female aged 59 that in 2000 is diagnosed with epidermoid carcinoma of clitoris, in 2004 is re-operated on by tumor relapse, and in 2009 she came again to our consultation and a vulvectomy, vagina resection and all gynecological system are carried out. Intervention concluded with an extraperitoneal vesical cutting. The tumor extends up to the initial portion of vagina and urethra. It is a malignant and well-differentiated tumor behaved in non habitual way with local relapses, when apparently the tumor was resected in all its extent, and in this last change, despite and advanced stage, there were neither tumor metastases nor multi-centralization. The postoperative course was free of complications receiving the discharge at fifth day.

    The aims of the review are to establish the number of undiagnosed neoplasms presenting at autopsy in a single centre and to determine the incidence and most common causes of sudden unexpected death due to neoplasia in infancy and childhood (SUDNIC). Retrospective observational study of paediatric autopsies performed on behalf of Her Majesty's Coroner over a 20-year period (1996-2015; n = 2,432). Neoplasms first diagnosed at autopsy were identified from an established database and cases meeting the criteria for sudden unexpected death were further categorised. Thirteen previously undiagnosed neoplasms were identified, including five haematological malignancies, two medulloblastomas, two neuroblastomas, two cardiac tumours and two malignancies of renal origin. Eight cases met the criteria for SUDNIC (0.33% of autopsies), the commonest group of which were haematological malignancies (n = 3). Neoplasms presenting as unexpected death in infancy and childhood and diagnosed at autopsy are rare. The findings suggest that haematological malignancies are the commonest cause of SUDNIC and highlight the importance of specialist autopsy in cases of sudden unexpected death. © 2017 Wiley Periodicals, Inc.

    Molecular pathology has been an integral part of the diagnostics of tumors of the hematopoietic system substantially longer than for solid neoplasms. In contrast to solid tumors, the primary objective of molecular pathology in hematopoietic neoplasms is not the prediction of drug efficacy but the diagnosis itself by excluding reactive proliferation and by using molecular features for tumor classification. In the case of malignant lymphomas, the most commonly applied molecular tests are those for gene rearrangements for immunoglobulin heavy chains and T-cell receptors. However, this article puts the focus on new and diagnostically relevant assays in hematopathology. Among these are mutations of MYD88 codon 265 in lymphoplasmacytic lymphomas, B-raf V600E in hairy cell leukemia and Stat3 exon 21 in indolent T-cell lymphomas. In myeloproliferative neoplasms, MPL W515, calreticulin exon 9 and the BCR-ABL and JAK2 V617F junctions are the most frequently analyzed differentiation series. In myelodysplastic and myeloproliferative neoplasms, SRSF2, SETBP1 and CSF3R mutations provide important differential diagnostic information. Genes mutated in myelodysplastic syndromes (MDS) are particularly diverse but their analysis significantly improves the differential diagnostics between reactive conditions and MDS. The most frequent changes in MDS include mutations of TET2 and various genes encoding splicing factors.

    Full Text Available Intraductal papillary mucinous neoplasm (IPMN of the pancreas is an intraductal mucin-producing epithelial neoplasm that arises from the main and/or branched pancreatic duct. It usually presents as cystic lesion of pancreas. There are well known differential diagnosis of cystic pancreatic lesion. Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use of abdominal imaging. The diagnosis and treatment of intraductal papillary mucinous tumors (IPMN of the pancreas has evolved over the past decade. IPMN represents a spectrum of disease, ranging from benign to malignant lesions, making the early detection and characterization of these lesions important. Definitive management is surgical resection for appropriate candidates, as benign lesions harbor malignant potential. IPMN has a prognosis, which is different from adenocarcinoma of the pancreas. We report a case of a 58-year-old male with intraductal papillary neoplasm involving main duct and side branches presenting to us with clinical symptoms of chronic pancreatitis with obstructive jaundice and cholangitis treated surgically.

    Full Text Available Santiago Palacios,1 María Jesús Cancelo2 1Palacios Institute of Women’s Health, Madrid, Spain; 2Gynecology and Obstetrics Department, Guadalajara University Hospital, University of Alcalá, Spain Abstract: The physiological decrease in vaginal estrogens is accountable for the emergence of vulvar and vaginal atrophy (VVA and its related symptoms such as vaginal dryness, dyspareunia, vaginal and/or vulvar irritation or itching, and dysuria. The repercussion of these symptoms on quality of life often makes it necessary to initiate treatment. Up until now, the treatments available included vaginal moisturizers and lubricants, local estrogens, and hormonal therapy. However, therapeutic options have now been increased with the approval of 60 mg ospemifene, the first nonhormonal oral treatment with an agonist effect on the vaginal epithelium and an endometrial and breast safety profile which makes it unique. This is the first selective estrogen receptor modulator indicated in women with moderate-to-severe vaginal atrophy not eligible for local estrogen treatment. Considering that “local estrogen noneligible women” are those in whom such treatment cannot be administered either because it is contraindicated or due to skill issues, who are averse to the mode and convenience of vaginal products’ administration or to their use on account of potential systemic absorption, or those who demonstrate dissatisfaction in terms of efficacy and safety, it is clear that there is a significant unmet medical need in VVA management. In fact, a great number of women show lack of adherence, dropping out of at least one VVA treatment, including nonhormonal moisturizers and lubricants, which they consider to be ineffective and uncomfortable. If they could choose, many of them may opt for oral treatment. In Phase III studies, ospemifene demonstrated efficacy in vaginal dryness and dyspareunia, regenerating vaginal cells, improving lubrication, and reducing pain

    Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.

    2010-01-01

    Background CDC25 phosphatases are important regulators of the cell cycle. Their abnormal expression detected in a number of tumors implies that their dysregulation is involved in malignant transformation. However, the role of CDC25s in vulvar cancer is still unknown. To shed light on their roles in the pathogenesis and to clarify their prognostic values, expression of CDC25A, CDC25B and CDC25C in a large series of vulvar squamous cell carcinomas were examined. ...

    2018-04-01

    Full Text Available The use of platelet-rich plasma (PRP for the treatment of lichen sclerosus (LS in a 38-year-old premenopausal woman is reported. The diagnosis was confirmed histologically and the symptoms documented using the ICIQ Vaginal Symptoms Questionnaire (ICIQ-VS and the Female Sexual Function Index (FSFI questionnaire. PRP was prepared from autologous blood using the Regen Cellular Matrix Kit. PRP was administered twice over two months. Histology at follow-up one month after the second administration showed the epidermis was nearly normal and upper dermal cellularity had been restored. The patient was symptom-free and both her ICIQ-VS and her FSFI scores had improved significantly. PRP is a potential new treatment option for LS which needs further assessment in randomized controlled trials. Keywords: Platelet-rich plasma, Vulvar lichen sclerosus, Premenopause, Treatment

  14. Post-coital burning pain and pain at micturition: early symptoms of partial vaginismus with or without vulvar vestibulitis?

    Science.gov (United States)

    Engman, Maria; Wijma, Klaas; Wijma, Barbro

    2008-01-01

    Twenty-four women with partial vaginismus with or without vulvar vestibulitis participated in a semi-structured telephone interview concerning early signs and development of their pain symptoms during/after intercourse. At the onset of the problem, pain after intercourse was more common than pain during penetration. Pain intensity during penetration increased from the onset of the problem to when the women ceased having intercourse. Pain during penetration lasted for 1 minute, and was most often described as sharp/incisive/bursting, while pain after intercourse had a duration of 2 hours and was described as burning and/or smarting. Post-coital pain during micturition was described by 70% of the women.

  15. Conscious sedation with inhaled 50% nitrous oxide/oxygen premix in photodynamic therapy sessions for vulvar lichen sclerosus treatment.

    Cabete, Joana; Campos, Sara; Lestre, Sara

    2015-01-01

    Photodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.

    Vulvar Paget disease is a rare skin disorder, which is most common in postmenopausal Caucasian women. They usually present with an erythematous plaque that may show fine or typical "cake icing" scaling or ulceration that may cause itching, pain, irritation, or a burning sensation. Although most cases are noninvasive, vulvar Paget disease may be invasive or associated with an underlying vulvar or distant adenocarcinoma. The histological evidence of so-called "Paget cells" with abundant pale cytoplasm in the epithelium confirms the diagnosis. The origin of these Paget cells is still unclear. Treatment of choice is wide local excision with negative margins. Obtaining clear surgical margins is challenging and may lead to extensive and mutilating surgery. Even then, recurrence rates are high, ranging from 15% to 70%, which emphasizes the need for new treatment options. A number of case reports, retrospective case series, and one observational study have shown promising results using the topical immune response modifier imiquimod. This study aims to investigate the efficacy, safety, and immunological response in patients with noninvasive vulvar Paget disease using a standardized treatment schedule with 5% imiquimod cream. Topical 5% imiquimod cream might be an effective and safe treatment alternative for vulvar Paget disease. The Paget Trial is a multicenter observational cohort study including eight tertiary referral hospitals in the Netherlands. It is ethically approved by the Medical-Ethical Committee of Arnhem-Nijmegen and registered in the Central Committee on Research Involving Human Subjects (CCMO) Register by as NL51648.091.14. Twenty patients with (recurrent) noninvasive vulvar Paget disease will be treated with topical 5% imiquimod cream three times a week for 16 weeks. The primary efficacy outcome is the reduction in lesion size at 12 weeks after end of treatment. Secondary outcomes are safety, immunological response, and quality of life. Safety will be

  17. Central Cemento-Ossifying Fibroma: Primary Odontogenic or Osseous Neoplasm?

    Science.gov (United States)

    Woo, Sook-Bin

    2015-12-01

    Currently, central cemento-ossifying fibroma is classified by the World Health Organization as a primary bone-forming tumor of the jaws. However, histopathologically, it is often indistinguishable from cemento-osseous dysplasias in that it forms osteoid and cementicles (cementum droplets) in varying proportions. It is believed that pluripotent cells within the periodontal membrane can be stimulated to produce either osteoid or woven bone and cementicles when stimulated. If this is true, cemento-ossifying fibroma would be better classified as a primary odontogenic neoplasm arising from the periodontal ligament. Cemento-ossifying fibromas also do not occur in the long bones. The present report compares several entities that fall within the diagnostic realm of benign fibro-osseous lesions and reviews the evidence for reclassifying central cemento-ossifying fibroma as a primary odontogenic neoplasm.

    Heller, Debra S

    2016-01-01

    In addition to practitioners who care for male patients, with the increased use of high-resolution anoscopy, practitioners who care for women are seeing more men in their practices as well. Some diseases affecting the penis can impact on their sexual partners. Many of the lesions and neoplasms of the penis occur on the vulva as well. In addition, there are common and rare lesions unique to the penis. A review of the scope of penile lesions and neoplasms that may present in a primary care setting is presented to assist in developing a differential diagnosis if such a patient is encountered, as well as for practitioners who care for their sexual partners. A familiarity will assist with recognition, as well as when consultation is needed.

  19. Myeloid Neoplasms in the Guise of Nutritional Deficiency

    2012-01-01

    The classic BCR-ABL-negative myeloproliferative neoplasms (MPNs) which include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are among the most frequent hematologic neoplasms. Because of their relatively smooth clinical course, it is likely that many of these MPNs actually go undetected. Considering the high prevalence of iron, folic-acid, and vitamin B12 deficiencies in developing countries, their coexistence with MPN can be expected frequently. In such situations where both disorders coexist, MPN is often overlooked. This causes considerable diagnostic delay. In this paper, two cases of PMF and one case of PV where the diagnosis of MPN was delayed for about 3 years are discussed. Presence of concomitant vitamin B12, folate, and iron deficiencies perhaps camouflaged the underlying MPN. Bearing in mind the possibility of MPN, even in the setting of apparent nutritional deficiency and performing a bone marrow evaluation, is the crucial step in unveiling the hidden MPN. PMID:23227377

  20. Intraductal papillary neoplasm of the bile duct: a case report.

    Peeters, Karen; Delvaux, Peter; Huysentruyt, Frederik

    2017-08-01

    Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors, characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic. The Western experience, however, remains limited. In this article, we report a 56-year-old man, referred to our hospital because of deranged liver function tests. Further imaging modalities showed a cystic lesion of 9 cm diameter, arising from the left hepatic duct. Inlying was a heterogeneous, lobulated mass. The patient underwent a left hemihepatectomy and adjuvant chemotherapy. Despite recent advanced technologies, diagnosis of IPNB is still challenging, especially in western countries due to its rarity. Early identification and resection of lesions, even in asymptomatic or minimally symptomatic patients, are however important prognostic factors.

  1. Food habits in atomic bomb survivors suffering from malignant neoplasms

    Morimoto, Kazue; Inoue, Hisako; Uchino, Chito

    1984-01-01

    Food habits were surveyed in patients admitted to 13 hospitals in Nagasaki prefecture and other prefectures to compare the incidence of malignant neoplasms according to the food intake between atomic bomb exposed group and non-exposed group. The incidence of malignant neoplasms was significantly higher in male patients having the low intake of milk and salted fish than in those having the high intake of them in atomic bomb exposed group, while it was significantly higher in male patients having the low intake of potatoes and milk and in female patients having the low intake of boiled fish paste than in those having the high intake of them in non-exposed group.

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare subtype of acute leukemia that typically follows a highly aggressive clinical course in adults, whereas experience in children with this disease is very limited. We report cases of two children in whom bone marrow showed infiltration by large atypical monocytoid 'blast-like' cells which on immunophenotyping expressed CD4, CD56, HLA-DR and CD33 while were negative for CD34 other T-cell, B-cell and myeloid markers. The differential diagnoses considered were AML, T/NK-cell leukemia and acute undifferentiated leukemia. Additional markers CD303/BDCA-2 and CD123 which are recently validated plasmacytoid dendritic cell markers were done which helped us clinch the diagnosis of this rare neoplasm. An accurate diagnosis of BPDCN is essential in order to provide prompt treatment. Due to its rarity and only recent recognition as a distinct clinicopathological entity, no standardized therapeutic approach has been established for BPDCN.

    2013-02-01

    Cathepsin K is consistently and diffusely expressed in alveolar soft part sarcoma (ASPS) and a subset of translocation renal cell carcinomas (RCCs). However, cathepsin K expression in human neoplasms has not been systematically analyzed. We constructed tissue microarrays (TMA) from a wide variety of human neoplasms, and performed cathepsin K immunohistochemistry (IHC). Only 2.7% of 1,140 carcinomas from various sites exhibited cathepsin K labeling, thus suggesting that among carcinomas, cathepsin K labeling is highly specific for translocation RCC. In contrast to carcinomas, cathepsin K labeling was relatively common (54.6%) in the 414 mesenchymal lesions studied, including granular cell tumor, melanoma, and histiocytic lesions, but not paraganglioma, all of which are in the morphologic differential diagnosis of ASPS. Cathepsin K IHC can be helpful in distinguishing ASPS and translocation RCC from some but not all of the lesions in their differential diagnosis.

Nearly all patients present initially with cutaneous manifestations, with many having extracutaneous disease additionally. While response to chemotherapy initially is effective, relapse occurs in most, with a leukemic phase ultimately developing. The prognosis is dismal. While most of the clinical and pathologic features are well described, the association and possible prognostic significance between peripheral blood absolute monocytosis (>1.0 K/µL and blastic plasmacytoid dendritic cell neoplasm have not been reported. We report a case of a 68-year-old man who presented with a rash for 4–5 months. On physical examination, there were multiple, dull-pink, indurated plaques on the trunk and extremities. Complete blood count revealed thrombocytopenia, absolute monocytosis of 1.7 K/µL, and a negative flow cytometry study. Biopsy of an abdominal lesion revealed typical features of blastic plasmacytoid dendritic cell neoplasm. Patients having both hematologic and nonhematologic malignancies have an increased incidence of absolute monocytosis. Recent studies examining Hodgkin and non-Hodgkin lymphoma patients have suggested that this is a negative prognostic factor. The association between

    Gastric neuroendocrine neoplasms (g-NENs) are a group of heterogeneous tumors arising from the endocrine cells of stomach. Most g-NENs progresses slowly and have a long disease course; however, some other g-NENs grow rapidly, similar to the progression of gastric adenocarcinoma. g-NENs have complex and diverse clinical manifestations and their prognosis and treatment strategies depend highly on clinical subtype, pathological grade, tumour stage, and other factors. Due to their low prevalence,...

    Primary invasive Extramammary Paget’s vulvar disease is a rare tumor that is challenging to control. Wide surgical excision represents the standard treatment approach for Primary invasive Extramammary Paget’s vulvar disease. The goal of the current study was to analyze the appropriate indications of radiotherapy in Primary invasive Extramammary Paget's vulvar disease because they are still controversial. We searched the Cochrane Gynecological Cancer Group Trials Register, Cochrane Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE database up to September 2015. Radiotherapy was delivered as a treatment in various settings: i) Radical in 28 cases (range: 60–63 Gy), ii) Adjuvant in 25 cases (range: 39–60 Gy), iii) Salvage in recurrence of 3 patients (63 Gy) and iv) Neoadjuvant in one patient (43.3 Gy). A radiotherapy field that covered the gross tumor site with a 2–5 cm margin for the microscopic disease has been used. Radiotherapy of the inguinal, pelvic or para-aortic lymph node should be considered only for the cases with lymph node metastases within these areas. Radiotherapy alone is an alternative therapeutic approach for patients with extensive inoperable disease or medical contraindications. Definitive radiotherapy can be used in elderly patients and/or with medical contraindications. Adjuvant radiotherapy may be considered in presence of risk factors associated with local recurrence as dermal invasion, lymph node metastasis, close or positive surgical margins, perineal, large tumor diameter, multifocal lesions, extensive disease, coexisting histology of adenocarcinoma or vulvar carcinoma, high Ki-67 expression, adnexal involvement and probably in overexpression of HER-2/neu. Salvage radiotherapy can be given in inoperable loco-regional recurrence and to those who refused additional surgery

    Gastrointestinal neoplasms can be cured by local resection as long as the lesions are in the early stage and have not metastasized. Endoscopic resection is a minimally invasive treatment for early-stage gastrointestinal neoplasms, and endoscopic submucosal dissection (ESD) is one type of endoscopic resection that has been developed in the past 10 years. For ESD to be a reliable, curative treatment for gastrointestinal neoplasms, it is necessary for the endoscopist to detect the lesion early, make a precise pretreatment diagnosis, ensure that the patient has the correct indication for endoscopic resection, and have the skill to perform ESD. For early lesion detection, endoscopists should pay attention to subtle changes in the surface structure, the color of the mucosa and the visibility of underlying submucosal vessels. Chromoendoscopy and magnifying endoscopy are useful for determining the margin of the lesions for pretreatment diagnosis, and endoscopic ultrasonography and magnifying endoscopy are useful for determining the depth of invasion. For ESD to be successful, local injection of sodium hyaluronate helps maintain mucosal elevation during dissection. Selecting the appropriate knife, using transparent hoods wisely, employing a good strategy that uses gravity, and having good control of bleeding are all needed to make ESD reliable.

    To investigate the prevalence of appendiceal pathology in women undergoing surgery for a suspected ovarian neoplasm and the predictive value of intraoperative findings to determine the need for appendectomy at the time of surgery. Retrospective analysis of patients who underwent oophorectomy and appendectomy during the same surgical procedures at the University of Virginia Health System from 1992 to 2007. Observations were stratified based on the nature (benign, borderline, or malignant) and histology (serous compared with mucinous) of the ovarian neoplasm, frozen compared with final pathological diagnosis, and the gross appearance of the appendix. Among the 191 patients identified, frozen section was consistent with seven mucinous and 35 serous carcinomas, 16 serous and 33 mucinous borderline tumors, 71 mucinous and serous cystadenomas, and 29 cases of suspected metastatic tumor from a gastrointestinal primary. The highest rates of coexisting appendiceal pathology were associated with serous ovarian cancers (94.4% of grossly abnormal and 35.3% of normal appendices) and ovarian tumors suspected to be of primary gastrointestinal origin (83.3% grossly abnormal and 60.0% normal appendices harbored coexisting mucinous neoplasms). Linear regression analysis revealed that appearance of the appendix and frozen section diagnosis of the ovarian pathology were statistically significant predictors of coexisting appendiceal pathology, but the latter was more important. The prevalence of coexisting, clinically significant appendiceal pathology is low with a frozen section diagnosis of serous or mucinous cystadenoma. Appendectomy is recommended when frozen section diagnosis is mucinous or serous ovarian carcinoma, borderline tumor or metastatic carcinoma of suspected gastrointestinal origin.

    We present a rare case of malignant epithelial neoplasm of the appendix, an uncommon disorder encountered in clinical practice, which poses a variety of diagnostic and therapeutic challenges. We report a particular case in which the appendix was abnormally located in the pelvis, mimicking an adnexal mass. Therefore, it was difficult to make the preoperative diagnosis on clinical examination, imaging studies and laboratory tests and we discovered the lesion during the diagnostic laparoscopy. No lymphadenopathy or mucinous ascites were found. The case was completely handled via the laparoscopic approach keeping the appendix intact during the operation. The frozen section, the detailed histopathology overview as well as multiple immunostaining with a complex panel of markers report diagnosed a low-grade appendiceal mucinous neoplasm (LAMN) with no invasion of the wall. No adjuvant therapy was considered needed. At a one-year follow-up oncological assessment, the patient was free of disease. In women with cystic mass in the right iliac fossa an appendiceal mucocele should be considered in the differential diagnosis. Laparoscopic appendectomy can represent an adequate operation for the appendiceal mucinous neoplasm if the histological report is clear and surgical precautionary measures are taken.

    Detection of flat neoplasia is a major challenge in colorectal cancer screening, as missed lesions can lead to the development of an unexpected `incident' cancer prior to the subsequent endoscopy. The use of a tryptophan-related autofluorescence has been reported to be increased in murine intestinal dysplasia. The emission spectra of cells isolated from human adenocarcinoma and normal mucosa of the colon were studied and showed markedly greater emission intensity from cancerous cells compared to cells obtained from the surrounding normal mucosa. A proto-type multispectral imaging system optimized for ultraviolet macroscopic imaging of tissue was used to obtain autofluorescence images of surgical specimens of colonic neoplasms and normal mucosa after resection. Fluorescence images did not display the expected greater emission from the tumor as compared to the normal mucosa, most probably due to increased optical absorption and scattering in the tumors. Increased fluorescence intensity in neoplasms was observed however, once fluorescence images were corrected using reflectance images. Tryptophan fluorescence alone may be useful in differentiating normal and cancerous cells, while in tissues its autofluorescence image divided by green reflectance may be useful in displaying neoplasms.

    Needle aspiration biopsy is commonly employed in the evaluation of thyroid nodules. Unfortunately, the cytologic finding of a 'follicular neoplasm' does not distinguish between a thyroid adenoma and a follicular cancer. The purpose of this study was to identify clinical parameters that characterize patients with an increased risk of having a thyroid follicular cancer who preoperatively have a 'follicular neoplasm' identified by needle aspiration biopsy. A total of 395 patients initially treated at Vancouver General Hospital and the British Columbia Cancer Agency between the years of 1965 and 1985 were identified and their data were entered into a computer database. Patients with thyroid adenomas were compared to patients with follicular cancer using the chi-square test and Student's t-test. Statistically significant parameters that distinguished patients at risk of having a thyroid cancer (p less than 0.05) included age greater than 50 years, nodule size greater than 3 cm, and a history of neck irradiation. Sex, family history of goiter or neoplasm, alcohol and tobacco use, and use of exogenous estrogen were not significant parameters. Patients can be identified preoperatively to be at an increased risk of having a follicular cancer and accordingly appropriate surgical resection can be planned

    Artificial insemination (AI) of sows with frozen-thawed semen usually results in lower pregnancy rates and litter sizes than the use of liquid preserved semen. The present study evaluated the effectiveness of vulvar skin temperature changes as a predictor of ovulation in sows and determined the fertility rates obtained after AI with frozen-thawed semen supplemented with rosmarinic acid (RA). Semen was collected from mature boars and cryopreserved in experimental extenders supplemented with or without 105 μM of RA. Multiparous sows were inseminated with a single dose of semen when vulvar skin temperature decreased to a value below 35 °C. Intrauterine insemination was performed using 1.5 × 109 spermatozoa. The sows were slaughtered 48 h after AI and the embryos and oocytes were recovered from the oviducts. Total and progressive motility, viability and acrosome integrity were significantly (P semen samples compared with the control. Fertilisation occurred in all sows inseminated in the study, although there were no significant differences between the experimental groups. Sows inseminated with RA-supplemented semen showed a slight increase in the number of embryos recovered as compared to sows inseminated with control semen. In conclusion, insemination according to vulvar skin temperature changes resulted in successful fertilisation in all sows, although supplementation of the freezing media with RA did not improve the fertilising ability of frozen-thawed boar sperm.

    The fumes from cooking oil, similar to cigarette smoke, contain numerous carcinogens such as polycyclic aromatic hydrocarbons, aromatic amines, nitro-polycyclic aromatic hydrocarbons, etc. In this study, we examined the association between exposure to cooking oil fumes and the risk of cervical intraepithelial neoplasm. The study population in this nested case-control study consisted of women above the age of 19 years living in Chia-Yi County, located in the southwestern Taiwan, who had received pap smear screening between October, 1999, and December, 2000 (n=32,466). The potential cases were women having lesions greater than cervical intraepithelium neoplasm II (≥CIN2) reconfirmed by cervical biopsy (n=116). The potential controls (case: control=1:2) were age-matched (±2 years) and residence-matched women who had normal pap smears within 6 months of the cases. In total, 100 cases and 197 controls were completely interviewed by public health nurses about cooking methods, ventilation, and other potential risk factors. Women who cooked at home in a kitchen (n=269) without the presence of a fume extractor at least once a week between the ages of 20 and 40 had a 2.29 times higher risk [95% confidence interval (CI)=1.08-4.87] of developing cervical intraepithelial neoplasm than those who did not cook once a week in such a kitchen during the same age span, after adjusting for other potential confounders. This finding was further strengthened by the finding that women who did not use the fume extractors had a 2.47 times higher risk (95% CI=1.15-5.32) of developing cervical intraepithelial neoplasm than women who cooked in kitchens with fume extractors that were always switched on while cooking. We also found a joint protective effect of fume extractor use among women older than 40 years (n=202) if they used the extractors during both age spans of their lives, ages 20-40 and >40 years. Comparing our findings on women more than 40 years old who used fume extractors during

    The new 'Developmental lineage classification of neoplasms' was described in a prior publication. The classification is simple (the entire hierarchy is described with just 39 classifiers), comprehensive (providing a place for every tumor of man), and consistent with recent attempts to characterize tumors by cytogenetic and molecular features. A taxonomy is a list of the instances that populate a classification. The taxonomy of neoplasia attempts to list every known term for every known tumor of man. The taxonomy provides each concept with a unique code and groups synonymous terms under the same concept. A Perl script validated successive drafts of the taxonomy ensuring that: 1) each term occurs only once in the taxonomy; 2) each term occurs in only one tumor class; 3) each concept code occurs in one and only one hierarchical position in the classification; and 4) the file containing the classification and taxonomy is a well-formed XML (eXtensible Markup Language) document. The taxonomy currently contains 122,632 different terms encompassing 5,376 neoplasm concepts. Each concept has, on average, 23 synonyms. The taxonomy populates 'The developmental lineage classification of neoplasms,' and is available as an XML file, currently 9+ Megabytes in length. A representation of the classification/taxonomy listing each term followed by its code, followed by its full ancestry, is available as a flat-file, 19+ Megabytes in length. The taxonomy is the largest nomenclature of neoplasms, with more than twice the number of neoplasm names found in other medical nomenclatures, including the 2004 version of the Unified Medical Language System, the Systematized Nomenclature of Medicine Clinical Terminology, the National Cancer Institute's Thesaurus, and the International Classification of Diseases Oncolology version. This manuscript describes a comprehensive taxonomy of neoplasia that collects synonymous terms under a unique code number and assigns each

    Full text: The purpose of this study was to determine the feasibility of sentinel lymph node detection using preoperative lymphoscintigraphy and intra-operative lymphatic mapping in patients with primary vulvar malignancies. Nine patients (29-84 years old) with primary vulvar malignancy were scheduled for sentinel node detection. Two patients had malignant melanoma of the vulva and seven had squamous cell carcinomas. Eight patients did not have a previous surgery of the primary tumour nor of the lymph nodes, one had an aspiration biopsy. Three hours before surgery 1-5 mCi of Tc-99m Dextran was injected intradermally in four points in the skin junction adjacent to the vulvar lesions. Static lymphoscintigraphy was performed using a planar GE gamma camera with a multipurpose low energy collimator, in anterior and lateral views. Images were displayed on a personal computer, through a Portable Imaging Processing software (PIP). In two cases a Siemens ECAM SPECT camera was used, due to necessity of having high-resolution images. Patten blue dye was injected in the junction between the skin and vulvar tumor, in the surgery room, after anaesthesia induction. Agamma probe (Navigator Gamma Guidance System) was used to detect the sentinel node. The activity in the sentinel node was measured in each case, before and after resection. Activity in the remaining tissue was also measured. Nodes were adequately placed in plastic bags and sent to pathology for H-E staining. Non-sentinel nodes were also resected and sent for pathology, except in two cases. Sentinel nodes (SN) were visualised on lymphoscintigraphy 1 to 5 minutes after injection of Tc-99m Dextran. In malignant melanoma drainage to the sentinel node was faster than for other tumours. There were five cases who had bilateral SN in inguinal regions, in other three cases, two SN were located on the same side, two in the inguinal region. In all cases the SN was identified corroborating to the skin mark and with enough

    According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not being an infiltration from another neoplasm, a relapse or a metastasis. It was the aim of the study to analyze the frequency of the occurrence of multiple neoplasms among patients suffering from uterine cervix cancer, with a special interest in coexistent neoplasms, the time of their occurrence and total 5-year survivals. The data from the Lower Silesian Cancer Registry concerning the years 1984-2009 formed the material of the present study. 5.3% of all cervix neoplasms occurred as multiple cancers. Cervix neoplasms were 13.4% of multiple neoplasms. On average, cervical cancer occurred as a subsequent cancer in 6 patients yearly (60.7% of the occurrences of cervical cancer were in the period of 5 years following treatment for the first neoplasm). 5-year survival in patients suffering from primarily multiple cervix neoplasms constituted 57% and was convergent with the results for all patients suffering from cervical cancer. Cervical cancer as the first neoplasm occurred in 287 patients, on average in 11 patients annually. In the period of the first 5 years after the treatment of cervical cancer, there were 42.8% occurrences of other cancers. Cervical neoplasms most frequently coexisted with cancers of the breast, lung and large intestine. The frequency of the occurrence of multiple neoplasm among cervical cancer patients is increasing. Most frequently they coexist with other tobacco-related neoplasms, those related to HPV infections and with secondary post-radiation neoplasms. These facts should be taken into consideration during post-treatment observation and when directing diagnostic

    In this study, we investigate in detail the morphological, clinical and molecular features of 71 consecutive patients with a diagnosis of myeloproliferative neoplasms, unclassifiable. We performed a meticulous morphological analysis and found that most of the cases displayed a hypercellular bone marrow (70%) with normal erythropoiesis without left-shifting (59%), increased granulopoiesis with left-shifting (73%) and increased megakaryocytes with loose clustering (96%). Megakaryocytes displayed frequent giant forms with hyperlobulated or bulbous nuclei and/or other maturation defects. Interestingly, more than half of the cases displayed severe bone marrow fibrosis (59%). Median values of hemoglobin level and white blood cells count were all within the normal range; in contrast, median platelets count and lactate dehydrogenase were increased. Little less than half of the patients (44%) showed splenomegaly. JAK2V617F mutation was detected in 72% of all patients. Among the JAK2-negative cases, MPLW515L mutation was found in 17% and CALR mutations in 67% of the investigated cases, respectively. Finally, by multiple correspondence analysis of the morphological profiles, we found that all but four of the cases could be grouped in three morphological clusters with some features similar to those of the classic BCR-ABL1-negative myeloproliferative neoplasms. Analysis of the clinical parameters in these three clusters revealed discrepancies with the morphological profile in about 55% of the patients. In conclusion, we found that the category of myeloproliferative neoplasm, unclassifiable is heterogeneous but identification of different subgroups is possible and should be recommended for a better management of these patients.

    To study the lifetime effects of irradiation during development, 1680 beagle dogs were given single, whole body exposures to 60Co gamma radiation at one of 6 pre- or postnatal ages. Four groups of 120 dogs each (480 or 29%) received 0.16 or 0.83 Gy at early prenatal times, 8 or 28 days postcoitus (dpc). Four groups of 120 dogs each (29%) received 0.16 or 0.83 Gy in the perinatal period at 55 dpc or 2 days postpartum (dpp). Groups of 120 and 240 dogs (21%) received 0.83 Gy at later postnatal times, 70 or 365 dpp, respectively. A group of 360 dogs (21%) were sham-irradiated. The youngest dogs are now 12 years old. Through 4 years of age, 20 dogs had neoplasms diagnosed. Five malignancies and one benign tumor were seen in the first two years, including the only fatal malignancies which occurred in 4 perinatally irradiated dogs. Up to two years of age, the other non-fatal malignancy and benign tumor were found in dogs irradiated at 365 dpp and 55 dpc. The remaining 14 neoplasms, 12 benign and 2 non-fatal malignant, were diagnosed between two and four years of age. Respective numbers of these benign and non-fatal malignant tumors found in control, perinatally irradiated, and all other irradiated dogs were 2 and 0; 5 and 1; and 5 and 1. Eight of the benign lesions were minute papillomas of the eyelids which were more frequent in the perinatally irradiated dogs. Overall, 71% (5 of 7) of the malignancies seen in the first four years of life occurred in the 29% of the dogs irradiated in the perinatal period. Sixty-seven percent (8 of 12) of all neoplasms, excluding eyelid papillomas, also occurred in perinatally irradiated dogs. These data suggest an increased risk for neoplasia after perinatal irradiation

We studied the underlying molecular and clinicopathological features to better understand the heterogeneity of colorectal neoplasms (CRNs.We evaluated both genetic (mutations of KRAS, BRAF, TP53, and PIK3CA, and microsatellite instability [MSI] and epigenetic (methylation status of nine genes or sequences, including the CpG island methylator phenotype [CIMP] markers alterations in 158 CRNs including 56 polypoid neoplasms (PNs, 25 granular type laterally spreading tumors (LST-Gs, 48 non-granular type LSTs (LST-NGs, 19 depressed neoplasms (DNs and 10 small flat-elevated neoplasms (S-FNs on the basis of macroscopic appearance.S-FNs showed few molecular changes except SFRP1 methylation. Significant differences in the frequency of KRAS mutations were observed among subtypes (68% for LST-Gs, 36% for PNs, 16% for DNs and 6% for LST-NGs (P<0.001. By contrast, the frequency of TP53 mutation was higher in DNs than PNs or LST-Gs (32% vs. 5% or 0%, respectively (P<0.007. We also observed significant differences in the frequency of CIMP between LST-Gs and LST-NGs or PNs (32% vs. 6% or 5%, respectively (P<0.005. Moreover, the methylation level of LINE-1 was significantly lower in DNs or LST-Gs than in PNs (58.3% or 60.5% vs. 63.2%, P<0.05. PIK3CA mutations were detected only in LSTs. Finally, multivariate analyses showed that macroscopic morphologies were significantly associated with an increased risk of molecular changes (PN or LST-G for KRAS mutation, odds ratio [OR] 9.11; LST-NG or DN for TP53 mutation, OR 5.30; LST-G for PIK3CA mutation, OR 26.53; LST-G or DN for LINE-1 hypomethylation, OR 3.41.We demonstrated that CRNs could be classified into five macroscopic subtypes according to clinicopathological and molecular differences, suggesting that different mechanisms are involved in the pathogenesis of colorectal tumorigenesis.

    Full Text Available Metanephric stromal tumor of kidney is a novel pediatric benign stromal specific renal neoplasm. A few cases have been reported in adults also. This tumor is usually centered in the renal medulla with a characteristic microscopic appearance which differentiates this lesion from congenital mesoblastic nephroma and clear cell sarcoma of the kidney. In most cases complete excision alone is curative. The differentiation of metanephric stromal tumor from clear cell sarcoma of the kidney will spare the child from the ill effects of adjuvant chemotherapy. In this communication we describe the gross and microscopic features of metanephric stromal tumor in a one-month-old child with good prognosis.

    Full Text Available Demyelinating pseudotumors are rare, benign, solitary intracranial space occupying lesions which masquerade cerebral neoplasms. Contrast MRI shows open ring enhancement which is fairly specific for this entity. Advanced MRI techniques like MR spectroscopy and magnetizing transfer techniques can help differentiating these lesions. NAA/Cr ratio is significantly elevated in central regions of demyelinating pseudotumors than in gliomas and other lesions. Presence of abundant foamy macrophages, lymphoid inflammatory infiltrates around blood vessels, sheets of gemistocytic astrocytes with well-developed processes, well defined border of the lesion absence of neovascularity and necrosis should help us diagnose demyelinating pseudotumor fairly confidently on histopathology.

    Full Text Available An acute presentation of a spontaneously ruptured Solid-Pseudopapillary Neoplasm (SPN in an 8 year old female is discussed with a review of the world literature. Our literature search revealed 15 other cases of ruptured SPN and with this case the total is now 16. Notably, 12 patients were 16 years of age or less at presentation as in our case. Although rupture of a SPN is rarely reported it appears to be more probable in the pediatric patient. Additionally, larger tumor size and trauma may be contributing factors.

    Full Text Available A rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium is called Ichthyosis uteri. Originally described as an endometrial response to iatrogenically-introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium.Here we report a case of intraepithelial neoplasm III, with ichthyosis uteri. A 75-years-old female with hypetension, underwent total abdominal hysterectomy with bilateral salphingo-ophorectomy for watery discharge per vaginal since four months.

    While complete molar pregnancies are rare, they are wrought with a host of potential complications to include invasive gestational trophoblastic neoplasia. Persistent gestational trophoblastic disease following molar pregnancy is a potentially fatal complication that must be recognized early and treated aggressively for both immediate and long-term recovery. We present the case of a 21-year-old woman with abdominal pain and presyncope 1 month after a molar pregnancy with a subsequent uterine rupture due to invasive gestational trophoblastic neoplasm. We will discuss the complications of molar pregnancies including the risks and management of invasive, metastatic gestational trophoblastic neoplasia. PMID:24106538

    Full Text Available Atopic dermatitis (AD is a chronic inflammatory skin disease. Myeloproliferative neoplasms (MPNs are hematopoietic malignancies caused by uncontrolled proliferation of hematopoietic stem/progenitor cells. Recent studies have described several mutant mice exhibiting both AD-like skin inflammation and MPN. Common pathways for skin inflammation encompass overexpression of thymic stromal lymphopoietin and reduced signaling of epidermal growth factor receptor in the epidermis, while overproduction of granulocyte-colony stimulating factor by keratinocytes and constitutive activation of Stat5 in hematopoietic stem cells are important for the development of MPN. The murine studies suggest the existence of a similar human disease tentatively termed the AD-MPN syndrome.

    Failure of the immune system to launch a strong and effective immune response to high-risk HPV is related to viral persistence and the development of anogenital (pre)malignant lesions such as vulvar intraepithelial neoplasia (VIN). Different forms of immunotherapy, aimed at overcoming the inertia of the immune system, have been developed and met with clinical success. Unfortunately these, in principal successful, therapeutic approaches also fail to induce clinical responses in a substantial number of cases. In this review, the authors summarize the traits of the immune response to HPV in healthy individuals and in patients with HPV-induced neoplasia. The potential mechanisms involved in the escape of HPV-induced lesions from the immune system indicate gaps in our knowledge. Finally, the interaction between the immune system and VIN is discussed with a special focus on the different forms of immunotherapy applied to treat VIN and the potential causes of therapy failure. The authors conclude that there are a number of pre-existing conditions that determine the patients' responsiveness to immunotherapy. An immunotherapeutic strategy in which different aspects of immune failure are attacked by complementary approaches, will improve the clinical response rate.

    Vulvar and vaginal atrophy (VVA) is a common complaint in postmenopausal women and consists of a variety of symptoms and strong repercussions that negatively affect comfort during sexual activity and ultimately impact quality of life. The EU and US REVIVE surveys have detected significant barriers in health-care professional management and educational programs that prevent correct diagnosis and effective treatment. This was common in both Europe and the US, but differential behaviors and patterns could be detected after reviewing the published results. The frequency of reporting VVA symptoms was lower in European participants. However, a better knowledge that VVA is a consequence of menopause was evident in Europe, probably in relation to more frequent gynecological visits and more frequent specialist visits as a referral health-care professional. Moreover, a trend towards an improved satisfaction with management by the health-care professional was observed in Europe. European participants acknowledged a significantly higher impact of VVA symptoms on sexual intercourse and partner interaction than North American (US) participants, and both cohorts were observed to have differences between their respective VVA symptom profiles. These observations have implications in the overall concerns that participants stated with long-term VVA medication and for the optimal therapeutic approach, providing evidence to support the concept that unexplored methods to improve management of patients with VVA remain.

    lymphoma is the most frequent lymphoid neoplasm in our country. Its diagnosis is based on histopathological findings. The lymph node imprint has been used for more than 40 years. The aim was to establish the sensitivity, specificity, positive predictive value and negative predictive value of lymph node imprint and estimate the inter-observer rate. we did an observational, retrospective, prolective study, based on the lymph node imprint obtained by excisional biopsies over a period of 6 years. the inclusion criteria was met on 199 samples, 27.1 % were considered as reactive (n = 54), 16.1 % Hodgkin lymphoma (n = 32), 40.2 % (n = 80) non-Hodgkin lymphoma and 16.6 % (n = 33) as metastatic carcinoma. Comparing with the final histopathology report, the sensitivity and specificity of lymph node imprint were 88 % (0.81-0.95) and 64 % (0.55-0.73) respectively, the positive predictive value was 67 % (0.59-0.76) and the negative predictive value was 86 % (0.79-0.94). The interobserver kappa index was 0.467. the lymph node imprint remains as a useful tool for the diagnosis of lymphoid neoplasm. The agreement between observers was acceptable.

    Only 1-2 % of all pediatric tumors occur in the liver. Two thirds of these tumors are malignant and almost all of the tumors cause clinical symptoms due to their mass effects. Besides the poor prognosis in most of the malignant tumors, for further treatment the origin and nature of the neoplasm has to be known. Due to the mostly unimpeded growth into the peritoneal cavity, the origin of the tumors is primarily often unclear and can non-invasively only be determined by advanced imaging techniques. The display of the macro- and microhistological key features of primary pediatric liver neoplasms, including hepatoblastoma (HB), infantile hemangioendothelioma (IHE), mesenchymal hamartoma (MH), undifferentiated (embryonal) sarcoma (UES), and hepatocellular carcinoma (HCC), together with their imaging representation by ultrasound, computed tomography, and magnetic resonance imaging, may deepen the understanding of the underlying pathology and its imaging appearance. Furthermore, in many cases sufficient information may be provided not only to differentiate benign from malignant tumors, but also to guide for adequate treatment. (orig.)

    Immunoglobulins are used to prevent or reduce infection risk in primary immune deficiencies and in settings which exploit its anti-inflammatory and immune-modulatory effects. Rigorous proof of immunoglobulin efficacy in persons with lympho-proliferative neoplasms, plasma cell myeloma, and persons receiving hematopoietic cell transplants is lacking despite many clinical trials. Further, there are few consensus guidelines or algorithms for use in these conditions. Rapid development of new therapies targeting B-cell signaling and survival pathways and increased use of chimeric antigen receptor T-cell (CAR-T) therapy will likely result in more acquired deficiencies of humoral immunity and infections in persons with cancer. We review immunoglobulin formulations and discuss efficacy and potential adverse effects in the context of preventing infections and in graft-versus-host disease. We suggest an algorithm for evaluating acquired deficiencies of humoral immunity in persons with hematologic neoplasms and recommend appropriate use of immunoglobulin therapy.

    Full Text Available Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the submucosa or a partial laryngectomy however, partial and total laryngectomies are associated with many postoperative complications. In contrast, the endoscopic approach allows for highly magnified visualization of the lesion in situ, which facilitates the surgical removal of the mass through videosurgery. With little manipulation of the affected area, the chances of postoperative complications are reduced, leading to a more rapid recovery.

    Neoplasms change over time through a process of cell-level evolution, driven by genetic and epigenetic alterations. However, the ecology of the microenvironment of a neoplastic cell determines which changes provide adaptive benefits. There is widespread recognition of the importance of these evolutionary and ecological processes in cancer, but to date, no system has been proposed for drawing clinically relevant distinctions between how different tumours are evolving. On the basis of a consensus conference of experts in the fields of cancer evolution and cancer ecology, we propose a framework for classifying tumours that is based on four relevant components. These are the diversity of neoplastic cells (intratumoural heterogeneity) and changes over time in that diversity, which make up an evolutionary index (Evo-index), as well as the hazards to neoplastic cell survival and the resources available to neoplastic cells, which make up an ecological index (Eco-index). We review evidence demonstrating the importance of each of these factors and describe multiple methods that can be used to measure them. Development of this classification system holds promise for enabling clinicians to personalize optimal interventions based on the evolvability of the patient’s tumour. The Evo- and Eco-indices provide a common lexicon for communicating about how neoplasms change in response to interventions, with potential implications for clinical trials, personalized medicine and basic cancer research.

    Full Text Available We report a case of exceedingly rare cutaneous neoplasm with histological features of malignancy and uncertain biological potential. The nodular, darkly pigmented facial tumor with central exulceration, size 12x10x7 mm, of the skin 61-year-old man preauricular left was completely exised.Histologically tumor consists of atypical squamous cells, which express signs of moderate to significant pleomorphism, mitotically active, with foci forming of parakeratotic horn cysts (“pearls”. Characteristically tumor also consists of large number of atypical melanocytes with multifocal pattern, inserted between atypical squamous cells, and which contain large amount of dark brown pigment melanin. Immunohistochemically, squamous cells stain positively with keratin (CK116, melanocytes were stained with S -100 protein, HMB 45, and vimentin, but failed to stain with CK 116.To our knowledge this is the sixth reported case in world literature. The follow-up time of four years no evidence of recurrence or metastasis, similar all reported cases, but it is too short period in estimation to guarantee a benign course. However, it appears that this group of neoplasm may have different prognosis from pure squamous carcinoma or malignant melanoma.

These diseases not only share overlapping chromosomal abnormalities but also a number of acquired somatic mutations. Recently, mutations in a putative tumor suppressor gene, ten-eleven translocation 2 (TET2 on chromosome 4q24 have been identified in 12% of patients with MPN. Additionally 4q24 chromosomal rearrangements in MPN, including TET2 deletions, have also been observed using conventional cytogenetics. The goal of this study was to investigate the frequency of genomic TET2 rearrangements in MPN using fluorescence in situ hybridization as a more sensitive method for screening and identifying genomic deletions. Among 146 MPN patients, we identified two patients (1.4% who showed a common 4q24 deletion, including TET2. Our observations also indicated that the frequency of TET2 deletion is increased in patients with an abnormal karyotype (5%.Keywords: TET2, myeloproliferative neoplasms, fluorescence in situ hybridization, cytogenetics

    Since the first description of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in the eighties, their identification has dramatically increased in the last decades, hand to hand with the improvements in diagnostic imaging and sampling techniques for the study of pancreatic diseases. However, the heterogeneity of IPMNs and their malignant potential make difficult the management of these lesions. The objective of this review is to identify the molecular characteristics of IPMNs in order to recognize potential markers for the discrimination of more aggressive IPMNs requiring surgical resection from benign IPMNs that could be observed. We briefly summarize recent research findings on the genetics and epigenetics of intraductal papillary mucinous neoplasms, identifying some genes, molecular mechanisms and cellular signaling pathways correlated to the pathogenesis of IPMNs and their progression to malignancy. The knowledge of molecular biology of IPMNs has impressively developed over the last few years. A great amount of genes functioning as oncogenes or tumor suppressor genes have been identified, in pancreatic juice or in blood or in the samples from the pancreatic resections, but further researches are required to use these informations for clinical intent, in order to better define the natural history of these diseases and to improve their management.

    The authors present 17 cases of malignant neurogenic neoplasms of the head and neck observed in the Department of Otolaryngology in the years 1948-1993. The latest opinions on etiopathology, diagnosis and treatment of these tumors were described. Age and sex of patients, localization of tumor, symptoms histopathology and treatment were analyzed. Progressions of the disease were estimated retrospectively. It has been proved that these tumors develop quickly, give pain and paresthesia. Their diagnosis is very difficult because of their submucosal growth and difficult histopathological interpretation. A characteristic feature of these neurogenic tumors is the ability to give distant metastases. This feature differentiates them from squamous neoplasms, which give mainly nodal metastases. All the patients were subjected to surgery combined with conventional or high voltage radiotherapy. The positive effect of combined chemotherapy in cases of esthesioneuroblastoma is worthy of note. The prognosis in these tumors is often unfavorable. In the group under discussion 13 patients died because of recurrences, two patients are considered to be cured and the remaining 2 patients have had no recurrence for 2 and 3 years. (author)

    To determine whether written information and/or counseling based on the WOMAN-PRO II Program decreases symptom prevalence in women with vulvar neoplasia by a clinically relevant degree, and to explore the differences between the 2 interventions in symptom prevalence, symptom distress prevalence, and symptom experience. A multicenter randomized controlled parallel-group phase II trial with 2 interventions provided to patients after the initial diagnosis was performed in Austria and Switzerland. Women randomized to written information received a predefined set of leaflets concerning wound care and available healthcare services. Women allocated to counseling were additionally provided with 5 consultations by an Advanced Practice Nurse (APN) between the initial diagnosis and 6months post-surgery that focused on symptom management, utilization of healthcare services, and health-related decision-making. Symptom outcomes were simultaneously measured 5 times to the counseling time points. A total of 49 women with vulvar neoplasia participated in the study. Symptom prevalence decreased in women with counseling by a clinically relevant degree, but not in women with written information. Sporadically, significant differences between the 2 interventions could be observed in individual items, but not in the total scales or subscales of the symptom outcomes. The results indicate that counseling may reduce symptom prevalence in women with vulvar neoplasia by a clinically relevant extent. The observed group differences between the 2 interventions slightly favor counseling over written information. The results justify testing the benefit of counseling thoroughly in a comparative phase III trial. Copyright © 2017 Elsevier Inc. All rights reserved.

    We aimed to assess the incidence of haematological neoplasms (HNs) in Castilla y León (2,5 million inhabitants) and its distribution by age, gender and histological type. The epidemiological profile based on the described variables of the 10,943 HNs diagnosed during a 10-years period was analyzed, compared with other studies. The overall age-adjusted incidence was 29.4 cases/10(5) inhabitants-year, with some geographical differences. The mean age was 67.3 years, with a turning point between the 6th-7th decades of life from which there was a very significant increase of incidence. Two relevant facts where simultaneous with advancing age: decreased lymphoid neoplasms incidence and increased low degree neoplasms incidence. Lymphoid low degree neoplasms accounted for half of the registered processes, showed the greatest preference for male and reached the mode before the rest of neoplasms. Myeloid neoplasms incidence (9.5) was higher than that reported in other European registries, specially compared to southern European countries, opposite to lymphoid neoplasms incidence (20.0). A higher myeloid neoplasms incidence and lower lymphoid one than expected was observed. The turning point of incidence is between the 6th-7th decades of life, with a preference for male that decreases with age. There is an increased incidence of HNs in the area where a higher density of potentially polluting facilities is concentrated. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    To summarize the current views and insights on associations between Helicobacter pylori (H. pylori)-related chronic gastritis and colorectal neoplasm, we reviewed recent studies to clarify whether H. pylori infection/H. pylori-related chronic gastritis is associated with an elevated risk of colorectal neoplasm. Recent studies based on large databases with careful control for confounding variables have clearly demonstrated an increased risk of colorectal neoplasm associated with H. pylori infection. The correlation between H. pylori-related chronic atrophic gastritis (CAG) and colorectal neoplasm has only been examined in a limited number of studies. A recent large study using a national histopathological database, and our study based on the stage of H. pylori-related chronic gastritis as determined by serum levels of H. pylori antibody titer and pepsinogen, indicated that H. pylori-related CAG confers an increased risk of colorectal neoplasm, and more extensive atrophic gastritis will probably be associated with even higher risk of neoplasm. In addition, our study suggested that the activity of H. pylori-related chronic gastritis is correlated with colorectal neoplasm risk. H. pylori-related chronic gastritis could be involved in an increased risk of colorectal neoplasm that appears to be enhanced by the progression of gastric atrophy and the presence of active inflammation.

    Full Text Available There is an immense clinical need for novel therapeutics for the treatment of angiogenesis-dependent calcified neoplasms such as osteosarcomas and bone metastases. We developed a new therapeutic strategy to target bone metastases and calcified neoplasms using combined polymer-bound angiogenesis inhibitors. Using an advanced "living polymerization" technique, the reversible addition-fragmentation chain transfer (RAFT, we conjugated the aminobisphosphonate alendronate (ALN, and the potent anti-angiogenic agent TNP-470 with N-(2-hydroxypropylmethacrylamide (HPMA copolymer through a Glycine-Glycine-Proline-Norleucine linker, cleaved by cathepsin K, a cysteine protease overexpressed at resorption sites in bone tissues. In this approach, dual targeting is achieved. Passive accumulation is possible due to the increase in molecular weight following polymer conjugation of the drugs, thus extravasating from the tumor leaky vessels and not from normal healthy vessels. Active targeting to the calcified tissues is achieved by ALN's affinity to bone mineral.The anti-angiogenic and antitumor potency of HPMA copolymer-ALN-TNP-470 conjugate was evaluated both in vitro and in vivo. We show that free and conjugated ALN-TNP-470 have synergistic anti-angiogenic and antitumor activity by inhibiting proliferation, migration and capillary-like tube formation of endothelial and human osteosarcoma cells in vitro. Evaluation of anti-angiogenic, antitumor activity and body distribution of HPMA copolymer-ALN-TNP-470 conjugate was performed on severe combined immunodeficiency (SCID male mice inoculated with mCherry-labeled MG-63-Ras human osteosarcoma and by modified Miles permeability assay. Our targeted bi-specific conjugate reduced VEGF-induced vascular hyperpermeability by 92% and remarkably inhibited osteosarcoma growth in mice by 96%.This is the first report to describe a new concept of a narrowly-dispersed combined polymer therapeutic designed to target both tumor and

    The purpose of this study was to identify the CT features required for differentiating mucin-producing cystic neoplasms of the liver (mucinous cystic neoplasms and cyst-forming intraductal papillary neoplasms of the bile duct) from solitary bile duct cysts. CT images of pathologically confirmed mucinous cystic neoplasms (n = 15), cyst-forming intraductal papillary neoplasms of the bile duct (n = 16), and solitary bile duct cysts (n = 31) were reviewed. Analysis of the CT findings included shape, presence of septa, location of septa (peripheral vs central), thickness of septa (thin vs thick), mosaic pattern, mural nodules, intracystic debris, calcification, upstream bile duct dilatation, downstream bile duct dilatation, and communication between a cystic lesion and the bile duct. The maximum size of a cystic lesion and the maximum size of the largest mural nodule were measured. The presence of septa, central septa, mural nodules, upstream bile duct dilatation, and downstream bile duct dilatation were found to be significant CT findings for differentiating mucinous cystic neoplasms and cyst-forming intraductal papillary neoplasms of the bile duct from solitary bile duct cysts (p bile duct were 87% (27 of 31) and 87% (27 of 31), respectively. When two of these five criteria were used in combination, the sensitivity and specificity for diagnosing mucinous cystic neoplasms and cyst-forming intraductal papillary neoplasms of the bile duct were 87% (27 of 31) and 87% (27 of 31), respectively [corrected]. With the use of specific CT criteria, mucin-producing cystic neoplasms of the liver can be differentiated from solitary bile duct cysts with a high degree of accuracy.

    Background Some authors have studied the relationship between the presence of polyps, adenomas and cancers of upper gastrointestinal tract (stomach and duodenum) and risk of colorectal polyps and neoplasms; however, the results are controversial, which may be due to study sample size, populations, design, clinical features, and so on. No meta-analysis, which can be generalized to a larger population and could provide a quantitative pooled risk estimate of the relationship, of this issue existed so far. Methods We performed a meta-analysis to evaluate risk of colorectal polyps or neoplasms in patients with polyps, adenomas or cancers in upper gastrointestinal tract comparing with controls. A search was conducted through PubMed, EMBASE, reference lists of potentially relevant papers, and practice guidelines up to 27 November 2013 without languages restriction. Odd ratios (ORs) were pooled using random-effects models. Results The search yielded 3 prospective and 21 retrospective case-control studies (n = 37152 participants). The principal findings included: (1) OR for colorectal polyps was 1.15 (95% CI, 1.04–1.26) in the gastric polyps group comparing with control groups; (2) Patients with gastric polyps and neoplasms have higher risk (OR, 1.31 [95% CI, 1.06–1.62], and 1.72 [95% CI, 1.42–2.09], respectively) of colorectal neoplasms comparing with their controls; and (3) Positive association was found between the presence of colorectal neoplasms and sporadic duodenal neoplasms (OR, 2.59; 95% CI, 1.64–4.11). Conclusions Findings from present meta-analysis of 24 case-control studies suggest that the prevalence of colorectal polyps was higher in patients with gastric polyps than in those without gastric polyps, and the risk of colorectal neoplasms increases significantly in patients with gastric polyps, neoplasms, and duodenal neoplasms. Therefore, screening colonoscopy should be considered for patients with upper gastrointestinal polyps and neoplasms. PMID

  10. Thyroid neoplasms after radiation therapy for adolescent acne vulgaris

    There is a potential hazard of thyroid cancer after exposure to external irradiation for the treatment of adolescent acne vulgaris. We noted a 60% incidence of thyroid carcinoma among 20 patients with such a history, who were operated on for thyroid nodules during a five-year period. Eighty-three percent of the patients with carcinoma had either a follicular or a mixed papillary-follicular carcinoma; 17% had a papillary carcinoma; 33% had regional node metastases; none had evidence of distant metastases. The interval between radiation exposure and thyroidectomy ranged from nine to 41 years. This association of thyroid neoplasms and a prior history of radiation for acne vulgaris may be coincidental and therefore remains to be proved by retrospective surveys of large numbers of treated patients with appropriate controls

    Gorlin syndrome is a rare autosomal dominant disorder exhibiting high penetrance and variable expressivity. It is characterized by facial dysmorphism, skeletal anomalies, multiple basal cell carcinomas, odontogenic keratocysts (OKC), palmar and plantar pits, bifid ribs, vertebral anomalies and a variety of other malformations. Various neoplasms, such as medulloblastomas, meningiomas, ovarian and cardiac fibromas are also found in this syndrome. To describe a twelve-year-old patient with Gorlin-Goltz syndrome, with basal cell carcinomas and promyelocytic leukemia developed after receiving craniospinal radiation for a medulloblastoma. Bifid ribs as well as mandibular and maxillar OKC were also diagnosed Conclusion: The patient with Gorlin-Goltz syndrome should receive close follow-up for early detection of malformations nd malignant neoplasias.

    Mutations in the JAK2 gene are thought to underlie the development of chronic myeloproliferative neoplasms (cMPN). Indeed, ≥95% of polycythemia vera patients, and half or more of essential thrombocythemia and primary myelofibrosis (PMF) patients, harbor the JAK2V617F mutation. Besides the JAK2V617F mutation, the JAK2 exon 12 deletion, the MPLW515L/K, and CALR mutation have been discovered and shown to be involved in the pathogenesis of these diseases. Based on these advancements in the study of cMPN, the JAK2 inhibitor was developed as a new therapy for PMF. Moreover, recent advancements in our ability to diagnose cMPN have paralleled the development of large clinical trials for patients with cMPN. This article provides explanatory information from these large clinical trials that is useful for the actual clinical practice of caring for patients with cMPN in Japan.

    Autopsy findings in 26 cases of malignant neoplasms treated with radiation were analysed and following results were obtained. 1. Causes of death except for neoplastic extension were 58% (15/26) and infection was the single predominant cause of death (73% : 11/15) with 50% (4/8) in lung cancer. 2. Distant metastases were found in 73% (19/26). In 7 cases, no obvious metastasis was found before and after autopsy. On the other hand, the patients with metastases over 2 organs before autopsy revealed metastases in 82% (9/11) to the other organs at autopsy. 3. Radiation therapy was effective and the primary tumor disappeared completely in 71% (10/14) with curative irradiation. In metastatic lesions, tumor cells were almost disappeared with dosage over 40 Gy. (author)

    In contrast to typical astrocytic tumors that show hypodense areas on computed tomographic images, some intracranial tumors show hyperdense areas on CT images. The major reasons for hyperdensity on CT images are hypercellular lesions, intratumoral calcification, and intratumoral hemorrhage. Malignant lymphomas, germinomas, and medulloblastomas show homogenous hyperdensity on CT images because of their hypercellularity. Tumorous lesions such as subependymal giant cell astrocytomas, oligodendrogliomas, ependymomas, central neurocytomas, craniopharyngiomas, and meningiomas often present with hyperdense calcified lesions on CT images. Intratumoral hemorrhage also causes hyperdensity on CT images, and is often associated with metastatic brain tumors, glioblastomas, pituitary adenomas, and rarely with any of the other intracranial tumors. Although magnetic resonance imaging is now the major diagnostic tool for diseases of the central nervous system, the first imaging studies for patients with neurologic symptoms are still CT scans. Hyperdense areas on CT images are a clue to making an accurate diagnosis of intracranial neoplasms. (author)

    Full Text Available While complete molar pregnancies are rare, they are wrought with a host of potential complications to include invasive gestational trophoblastic neoplasia. Persistent gestational trophoblastic disease following molar pregnancy is a potentially fatal complication that must be recognized early and treated aggressively for both immediate and long-term recovery. We present the case of a 21-year-old woman with abdominal pain and presyncope 1 month after a molar pregnancy with a subsequent uterine rupture due to invasive gestational trophoblastic neoplasm. We will discuss the complications of molar pregnancies including the risks and management of invasive, metastatic gestational trophoblastic neoplasia. [West J Emerg Med. 2013;14(5:444–447.

    A method and the apparatus for the treatment of neoplasms with Au/sup 198/ seeds are described. The introducer or gun is loaded with a magazine or cartridge containing 15 radioactive gold grains and then irradiated. The grains are cylinders made of gold encased in Pt with measurements of: length, 2.1 mm; diameter, 0.4 mm; weight, 25 mgm; platinum casing, 0.2 mm. The seeds are ready for use 7 to 10 days after irradiation or when gamma activity is around 3 to 4.5 mC per seed. A permanent implant gives to the tumor an approximate dose of 6000- 7000 r in 4 to 5 days. The effectiveness and advantages of the method are also discussed. (P.C.H.)

    1984-01-01

    The data of an epidemiologic study of multiple primary malignant neoplasms in breast cancer patients in Israel are presented. During the 18-year period of the study 12,302 cases of breast carcinoma were diagnosed, and, of these, 984 patients (8%) had multiple primary malignant tumors. Forty-seven of these patients developed two multiple primary cancers. A significantly higher than expected incidence of second primary cancers occurred at the following five sites: the opposite breast, salivary glands, uterine corpus, ovary, and thyroid. Cancers of the stomach and gallbladder were fewer than expected. Treatment of the breast cancer by irradiation was associated with an increased risk of subsequent cancers of lung and hematopoietic system. The prognosis was mainly influenced by the site and malignancy of the second primary cancer. The incidence of multiple primary malignancies justifies a high level of alertness to this possibility in the follow-up of breast cancer patients

    Full Text Available Abstract We studied non-driver mutations in 62 subjects with myeloproliferative neoplasm (MPN-associated myelofibrosis upon diagnosis, including 45 subjects with primary myelofibrosis (PMF and 17 with post-polycythemia vera or post-essential thrombocythemia myelofibrosis (post-PV/ET MF. Fifty-eight subjects had ≥1 non-driver mutation upon diagnosis. Mutations in mRNA splicing genes, especially in U2AF1, were significantly more frequent in PMF than in post-PV/ET MF (33 vs. 6%; P = 0.015. There were also striking differences in clonal architecture. These data indicate different genomic spectrums between PMF and post-PV/ET MF.

    The binding of human luteinizing hormone and human follicle-stimulating hormone to ovarian tumor biopsy specimens from 29 patients was analyzed. The binding sites for human luteinizing hormone were demonstrated in one tumor of epithelial origin (mucinous cystadenoma) and in one of sex cord-stromal origin (theca cell tumor). The binding sites for human follicle-stimulating hormone were found in three tumors of epithelial origin (serous cystadenoma and mucinous cystadenoma) and in two of sex cord-stromal origin (theca cell tumor and theca-granulosa cell tumor). The surface-binding autoradiographic study revealed that the binding sites for gonadotropins were localized in the stromal tissue. The results suggest that gonadotropic hormones may play a role in the growth and differentiation of a certain type of human ovarian neoplasms

    Due to modern examination techniques such as multidetector computed tomography and high-field magnetic resonance imaging, the detection rate of renal neoplasms is continually increasing. Even though tumors exceeding 4 cm in diameter rarely metastasize, all renal lesions that are possible neoplasms should be treated. Traditional treatment techniques include radical nephrectomy or nephron-sparing resection, which are increasingly performed laparoscopically. Modern thermal ablation techniques such as hyperthermal techniques like radiofrequency ablation RFA, laser induced thermal ablation LITT, focused ultrasound FUS and microwave therapy MW, as well as hypothermal techniques (cryotherapy) may be a useful treatment option for patients who are unfit for or refuse surgical resection. Cryotherapy is the oldest and best known thermal ablation technique and can be performed laparoscopically or percutaneously. Since subzero temperatures have no antistyptic effect, additional maneuvers must be performed to control bleeding. Percutaneous cryotherapy of renal tumors is a new and interesting method, but experience with it is still limited. Radiofrequency ablation is the most frequently used method. Modern probe design allows volumes between 2 and 5 cm in diameter to be ablated. Due to hyperthermal tract ablation, the procedure is deemed to be safe and has a low complication rate. Although there are no randomized comparative studies to open resection, the preliminary results for renal RFA are promising and show RFA to be superior to other thermal ablation techniques. Clinical success rates are over 90% for both, cryo- and radiofrequency ablation. Whereas laser induced thermal therapy is established in hepatic ablation, experience is minimal with respect to renal application. For lesions of more than 2 cm in diameter, additional cooling catheters are required. MR thermometry offers temperature control during ablation. Microwave ablation is characterized by small ablation volumes

    Blastic plasmacytoid dendritic cell neoplasm (BPDNC) is a rare tumour, which stems from plasmacytoid dendritic cells. Although the aetiology is still unclear, in the last few years various reports suggested a potential role of chromosomal aberrations in the oncogenesis. The disease is currently enclosed among "acute myeloid leukemia (AML) and related precursor neoplasms" in the last WHO classification. BPDCN has an aggressive course, however, it has been suggested that an exclusive cutaneous involvement at presentation is related to a better clinical outcome. We review the literature about BPDCN, and we present a series of 11 cases, all characterised by disease limited to the skin at presentation. Furthermore, we examined all cases of the last 10 years stored in the database of the multidisciplinary study group on cutaneous lymphomas of the University of Florence. Basing on the clinical features, patient were classified into two groups: with a single-lesion or multiple eruptive-lesions presentation. The former were treated with radiotherapy (limited field, electron beam therapy). The latter were treated with different therapeutic options, depending on age and co-morbidities. All patients with a single lesion achieved complete response. Five of 6 patients with eruptive lesions achieved a clinical response (2 complete and 3 partial response). Notably, the progression free survival was higher in the single-lesion than in the eruptive-lesion group (23 vs. 9 months). However all patients relapsed and 8 of 11 died. Although the small number of selected patients, we could speculate that the concept of "cutaneous sanctuary" is particularly true in patients with a single lesion-presentation. In these patients, especially if >70 year-old aged, radiotherapy should be encouraged as the treatment of choice.

    2011-10-01

    Sentinel lymph node (SLN) dissections have been shown to be sensitive for the evaluation of nodal basins for metastatic disease and are associated with decreased short-term and long-term morbidity when compared with complete lymph node dissection. There has been increasing interest in the use of SLN technology in gynecologic cancers. This review assesses the current evidence-based literature for the use of SLN dissections in gynecologic malignancies. Recent literature continues to support the safety and feasibility of SLN biopsy for early stage vulvar cancer with negative predictive value approaching 100 % and low false negative rates. Alternatively, for endometrial cancer most studies have reported low false-negative rates, with variable sensitivities and have reported low detection rates of the sentinel node. Studies examining the utility of SLN biopsy in early-stage cervical cancer remain promising with detection rates, sensitivities, and false-negative rates greater than 90 % for stage 1B1 tumors. SLN dissections have been shown to be effective and safe in certain, select vulvar cancer patients and can be considered an alternative surgical approach for these patients. For endometrial and cervical cancer, SLN dissection continues to have encouraging results and however needs further investigation.

    Cystic hepatic neoplasms are rare tumors, and are classified into two separate entities: mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms of the bile duct (IPMN-B). We report the case of a 56-year-old woman who presented with abdominal pain and jaundice due to the presence of a large hepatic multilocular cystic tumor associated with an intraductal tumor. Partial hepatectomy with resection of extrahepatic bile ducts demonstrated an intrahepatic MCN and an intraductal IPMN-B. This is the first report of the simultaneous occurrence of these two histologically distinct entities in the liver.

    2017-01-01

    Full Text Available While growing use of comprehensive mutational analysis has led to the discovery of innumerable genetic alterations associated with various myeloid neoplasms, the under-recognized phenomenon of genetic heterogeneity within such neoplasms creates a potential for diagnostic confusion. Here, we describe two cases where expanded mutational testing led to amendment of an initial diagnosis of chronic myelogenous leukemia with subsequent altered treatment of each patient. We demonstrate the power of comprehensive testing in ensuring appropriate classification of genetically heterogeneous neoplasms, and emphasize thoughtful analysis of molecular and genetic data as an essential component of diagnosis and management.

    There is a paucity of literature describing and comparing the imaging features of adrenocortical adenomas and carcinomas in children and adolescents. To document the CT and MRI features of adrenocortical neoplasms in a pediatric population and to determine whether imaging findings (other than metastatic disease) can distinguish adenomas from carcinomas. We searched institutional medical records to identify pediatric patients with adrenocortical neoplasms. Pre-treatment CT and MRI examinations were reviewed by two radiologists in consensus, and pertinent imaging findings were documented. We also recorded relevant histopathological, demographic, clinical follow-up and survival data. We used the Student's t-test and Wilcoxon rank sum test to compare parametric and nonparametric continuous data, and the Fisher exact test to compare proportions. We used receiver operating characteristic (ROC) curve analyses to evaluate the diagnostic performances of tumor diameter and volume for discriminating carcinoma from adenoma. A P-value ≤0.05 was considered statistically significant. Among the adrenocortical lesions, 9 were adenomas, 15 were carcinomas, and 1 was of uncertain malignant potential. There were no differences in mean age, gender or sidedness between adenomas and carcinomas. Carcinomas were significantly larger than adenomas based on mean estimated volume (581 ml, range 16-2,101 vs. 54 ml, range 3-197 ml; P-value = 0.003; ROC area under the curve = 0.92) and mean maximum transverse plane diameter (9.9 cm, range 3.0-14.9 vs. 4.4 cm, range 1.9-8.2 cm; P-value = 0.0001; ROC area under the curve = 0.92). Carcinomas also were more heterogeneous than adenomas on post-contrast imaging (13/14 vs. 2/9; odds ratio [OR] = 45.5; P-value = 0.001). Six of 13 carcinomas and 1 of 8 adenomas contained calcification at CT (OR = 6.0; P-value = 0.17). Seven of 15 children with carcinomas exhibited metastatic disease at diagnosis, and three had inferior vena cava invasion. Median

Carcinomas were significantly larger than adenomas based on mean estimated volume (581 ml, range 16-2,101 vs. 54 ml, range 3-197 ml; P-value = 0.003; ROC area under the curve = 0.92) and mean maximum transverse plane diameter (9.9 cm, range 3.0-14.9 vs. 4.4 cm, range 1.9-8.2 cm; P-value = 0.0001; ROC area under the curve = 0.92). Carcinomas also were more heterogeneous than adenomas on post-contrast imaging (13/14 vs. 2/9; odds ratio [OR] = 45.5; P-value = 0.001). Six of 13 carcinomas and 1 of 8 adenomas contained calcification at CT (OR = 6.0; P-value = 0.17). Seven of 15 children with carcinomas exhibited metastatic disease at diagnosis, and three had inferior vena cava invasion. Median

    The Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) including polycythemia vera, essential thrombocythemia and primary myelofibrosis are clonal hematological malignancies that originate at the level of the hematopoietic stem cell, and are characterized by excessive proliferation of cells belonging to one or more of the myeloid lineages. Central to the pathogenesis of the MPNs is constitutive activation of the JAK/STAT signaling pathway due to a family of driver mutations affecting JAK2, CALR or MPL. These disorders share common clinical and laboratory features, a significant burden of systemic symptoms, increased risk of developing arterial and venous thrombotic events, and the potential to progress to myelofibrosis and acute leukemia. Areas covered: We identified four clinical situations which represent challenging management dilemmas for patients with MPNs. Our conclusions and recommendations are based on a literature search using MEDLINE and recent meeting abstracts using the keywords, focusing on publications directly addressing these scenarios and on recent contributions to the field. Expert commentary: Multi-center efforts to study large cohorts of MPN patients have led to more uniform and evidence-based approaches to key aspects in MPN management. However, treatment strategies to deal with specific clinical scenarios are lacking.

  20. Second neoplasms following radiotherapy or chemotherapy for cancer

    While radiotherapy and antineoplastic chemotherapy often control malignancies they may, paradoxically, cause new cancers to develop as long-term complications. Although almost any type of neoplasm can occur, radiation-induced malignancies are most likely to affect the myelopoietic tissues and the thyroid gland. The former tissues are also most frequently involved by chemotherapy. The combination of intensive radiotherapy and intensive chemotherapy is particularly leukemogenic. Acute myeloid leukemia has occurred with increased frequency following treatment of Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, ovarian cancer, polycythemia vera, carcinoma of the thyroid gland, and carcinoma of the breast. Radiation-induced malignancies usually occur in the field of irradiation. Tumors developing in an irradiated field include a substantial number of soft tissue sarcomas or osteosarcomas. There is a 20-fold increase of second cancers following treatment of childhood malignancies, mostly sarcomas of bone and soft tissues, but including leukemia, and carcinomas of the thyroid gland, skin, and breast. The latent period between radiotherapy and the appearance of a second cancer ranges from 2 years to several decades, often being 10-15 years. With chemotherapy the mean latent period is shorter, approximately 4 years. The mechanism of oncogenesis by radiotherapy or chemotherapy is poorly understood and probably involves a complex interplay of somatic mutation, co-oncogenic effects, depression of host immunity, stimulation of cellular proliferation, and genetic susceptibility

    Receptors for regulatory peptides, such as somatostatin or vasoactive intestinal peptide (VIP), expressed at high density by neoplastic cells, can be instrumental for tumor diagnosis and therapy. Little is known about the expression of neurotensin receptors in human tumors. In the present study, 464 human neoplasms of various types were investigated for their neurotensin receptor content by in vitro receptor autoradiography on tissue sections using 125I-[Tyr3]-neurotensin as radioligand. Neurotensin receptors were identified and localized in tumor cells of 11/17 Ewing's sarcomas, 21/40 meningiomas, 10/23 astrocytomas, 5/13 medulloblastomas, 7/24 medullary thyroid cancers and 2/8 small cell lung cancers. They were rarely found in non-small cell lung cancers and breast carcinomas; they were absent in prostate, ovarian, renal cell and hepatocellular carcinomas, neuroendocrine gut tumors, pituitary adenomas, schwannomas, neuroblastomas and lymphomas. When present, the receptors bound with nanomolar affinity neurotensin and acetyl-neurotensin-(8-13), with lower affinity neuromedin N, diethylenetriamine penta-acetic acidneurotensin-(8-13) and SR 48692, but not neurotensin-(1-11). They were all of the NT1 type, without high affinity for levocabastine. Further, in 2 receptor-positive Ewing's sarcomas, neurotensin mRNA was detected by in situ hybridization techniques. Since neurotensin is known to stimulate cell proliferation, the presence of neurotensin receptors in human neoplasia may be of biological relevance, possibly as an integrative part of an autocrine feedback mechanism of tumor growth stimulation.

    Full Text Available Mucinous cystic neoplasms (MCNs make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian organs such as pancreas, hepatobiliary tract and mesentery. MCNs of the pancreas occur almost exclusively in women. Here, we report a rare case of MCN in a male patient. A 39-year-old man was admitted to our hospital with the chief complaint of back pain. Abdominal computed tomography revealed a multilocular cyctic mass 6.3 cm in diameter in the pancreatic tail. In addition, the outer wall and septae with calcification were demonstrated in the cystic lesion. On magnetic resonance imaging , the cystic fluid had low intensity on T1-weighted imaging and high intensity on T2-weighted imaging. Endoscopic retrograde cholangio-pancreatography (ERCP showed neither communication between the cystic lesion and the main pancreatic duct nor encasement of the main pancreatic duct. Endoscopic ultrasonography revealed neither solid component nor thickness of the septae in the cystic lesion. Consequently, we performed distal pancreatectomy with splenectomy under the diagnosis of cystic neoplasia of the pancreas. Histopathologically, the cystic lesion showed two distinct component: an inner epithelial layer and an outer densely cellular ovarian-type stromal layer. Based on these findings, the cystic lesion was diagnosed as MCN.

    With the discovery in the last 3 years of novel Janus kinase 2 (JAK2) and thrombopoietin receptor (MPL) mutations, the pathogenetic understanding of and clinical practice for myeloproliferative neoplasms (MPNs) have entered a new era. Each one of these newly discovered mutations, including JAK2V617F, MPLW515L, and a JAK2 exon 12 mutation, has been shown to result in constitutive activation of JAK-STAT signaling and also induce a MPN phenotype in mice. Thus, JAK2 is now considered to be a legitimate target for drug development in MPNs, and small molecule JAK2 inhibitors have already gone through successful preclinical testing, and early-phase human trials in primary myelofibrosis have already begun. Furthermore, JAK2 mutation screening has now become a front-line diagnostic test in the evaluation of both "erythrocytosis" and thrombocytosis and the 2001 World Health Organization diagnostic criteria for polycythemia vera, essential thrombocythemia, and primary myelofibrosis have now been revised to incorporate JAK2V617F mutation screening.

    The majority of patients with BCR-ABL1-negative myeloproliferative neoplasms (MPN) harbor mutations in JAK2 or MPL, which lead to constitutive activation of the JAK/STAT, PI3K and ERK signaling pathways. JAK inhibitors by themselves are inadequate in producing selective clonal suppression in MPN and are associated with hematopoietic toxicities. MK-2206 is a potent allosteric AKT inhibitor that was well tolerated, including no evidence of myelosuppression, in a phase I study of solid tumors. Herein, we show that inhibition of PI3K/AKT signaling by MK-2206 affected the growth of both JAK2V617F- or MPLW515L-expressing cells via reduced phosphorylation of AKT and inhibition of its downstream signaling molecules. Moreover, we demonstrate that MK-2206 synergizes with ruxolitinib in suppressing the growth of JAK2V617F-mutant SET2 cells. Importantly, MK-2206 suppressed colony formation from hematopoietic progenitor cells in patients with primary myelofibrosis and alleviated hepatosplenomegaly and reduced megakaryocyte burden in the bone marrows, livers and spleens of mice with MPLW515L-induced MPN. Together, these findings establish AKT as a rational therapeutic target in the MPNs.

    A survey was made on 7,589 admitted patients and 1,965 autopsy cases. The overall incidence of malignant neoplasms tended to decrease in the group exposed to atomic bomb within 2 km in autopsy cases and to increase in admitted patients. The incidence of pulmonary cancer tended to increase in both autopsy cases and admitted patients. The incidence of gastric cancer tended to increase up to 1975, and thereafter tended to decrease. The incidence of liver cancer tended to increase in both autopsy cases and admitted patients, which was marked in males. The incidence of leukemia was high in the group exposed to atomic bomb within 2 km in autopsy cases, and in the group within 1 km and the group which entered the city after the explosion in admitted patients. The incidence of malignant lymphoma tended to decrease, and the incidence of carcinoma of the colon tended to gradually increase in both autopsy cases and admitted patients. The incidence of multiple carcinomas tended to increase in both atomic bomb exposed group and non-exposed group, being higher in atomic bomb group than in non-exposed group. The incidence of breast cancer became constant since 1970. The incidence of carcinoma of the thyroid gland tended to decrease, although it was high in the group exposed near the explosion.

    The classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), which include polycythaemia vera, essential thrombocythaemia and primary myelofibrosis, originate from a stem cell-derived clonal myeloproliferation that manifests itself with variable haematopoietic cell lineage involvement; they are characterized by a high degree of similarities and the chance to transform each to the other and to evolve into acute leukaemia. Their molecular pathogenesis has been associated with recurrent acquired mutations in janus kinase 2 (JAK2) and myeloproliferative leukemia virus oncogene (MPL). These discoveries have simplified the diagnostic approach and provided a number of clues to understanding the phenotypic expression of MPNs; furthermore, they represented a framework for developing and/or testing in clinical trials small molecules acting as tyrosine kinase inhibitors. On the other hand, evidence of abnormal epigenetic gene regulation as a mechanism potentially contributing to the pathogenesis and the phenotypic diversity of MPNs is still scanty; however, study of epigenetics in MPNs represents an active field of research. The first clinical trials with epigenetic drugs have been completed recently, whereas others are still ongoing; results have been variable and at present do not allow any firm conclusion. Novel basic and translational information concerning epigenetic gene regulation in MPNs and the perspectives for therapy will be critically addressed in this review. PMID:19522842

    With the intent of dissecting the molecular complexity of Philadelphia-negative myeloproliferative neoplasms (MPN), we designed a target enrichment panel to explore, using next-generation sequencing (NGS), the mutational status of an extensive list of 2000 cancer-associated genes and microRNAs. The genomic DNA of granulocytes and in vitro-expanded CD3+T-lymphocytes, as a germline control, was target-enriched and sequenced in a learning cohort of 20 MPN patients using Roche 454 technology. We identified 141 genuine somatic mutations, most of which were not previously described. To test the frequency of the identified variants, a larger validation cohort of 189 MPN patients was additionally screened for these mutations using Ion Torrent AmpliSeq NGS. Excluding the genes already described in MPN, for 8 genes (SCRIB, MIR662, BARD1, TCF12, FAT4, DAP3, POLG and NRAS), we demonstrated a mutation frequency between 3 and 8%. We also found that mutations at codon 12 of NRAS (NRASG12V and NRASG12D) were significantly associated, for primary myelofibrosis (PMF), with highest dynamic international prognostic scoring system (DIPSS)-plus score categories. This association was then confirmed in 66 additional PMF patients composing a final dataset of 168 PMF showing a NRAS mutation frequency of 4.7%, which was associated with a worse outcome, as defined by the DIPSS plus score.

    A total of 38 patients (18 female/20 male) with childhood meningioma were recruited from the German registry HIT-Endo (1989-2009). In 5 cases meningioma occurred as second malignant neoplasm (SMN). Histologies were confirmed by reference assessment in all cases (SMN: 2 WHO I, 1 WHO II, 2 WHO III). The SMNs were diagnosed at a median age of 12.4 years with a median latency of 10.2 years after primary malignancy (PMN; 4 brain tumors, 1 lymphoblastic leukemia; median age at diagnosis 2.7 years). Meningioma occurred as SMN in the irradiated field of PMN (range 12-54 Gy). The outcome after treatment of SMN meningioma (surgery/irradiation) was favorable in terms of psychosocial status and functional capacity in 4 of 5 patients (1 death). We conclude that survivors of childhood cancer who were exposed to radiation therapy at young age harbor the risk of developing meningioma as a SMN at a particularly short latency period in case of high dose exposure.

    Full Text Available Parathyroid carcinoma is an extremely rare malignant endocrine neoplasm that is very challenging in its diagnosis as well as its treatment. Clinically the disease is detected earlier in patients who present with hyperparathyroidism with signs of profound hypercalcemia. Differentiation between benign and malignant disease of the parathyroid is challenging both for the clinician and for the pathologist. Complete surgical resection at the time of first operation offers the best chance of cure. Even after radical excision which is the standard management, local recurrence and metastases are frequent. The disease usually has a slow indolent course and most patients suffer from complications of hypercalcemia rather than tumor invasion or metastasis.We report a case of a 31-year-old woman who presented with renal colic. Various hematological, biochemical and radiological investigations were performed and a slightly enlarged right parathyroid was found. A clinical diagnosis of parathyroid adenoma was made and a right parathyroidectomy was done. Intraoperatively the surgeon had no suspicion of malignancy but microscopically the lesion was malignant and a final diagnosis of parathyroid carcinoma was rendered based on the criteria of invasion. Since there is no gold standard, a multidisciplinary approach, including the entire clinical, biochemical, radiological and pathological profile of the disease aids in an accurate diagnosis. Here we are reporting a case of a functional parathyroid carcinoma presenting in a relatively young patient with all the biochemical and radiological investigations and findings pointing towards a benign parathyroid disease.

    Full Text Available Laryngeal neoplasm contributes to 30-40% of carcinomas of the head and neck. Mast cells are normal connective tissue residents, well represented in the respiratory tract. Experimental evidence suggests that the growth of a tumor beyond a certain size requires angiogenesis, which may also permit metastasis. The aim of this study was to evaluate the correlation between mast cell density, microvascular density, histopathological type and histological grade. Our study included 38 laryngeal carcinomas as follows: adenoid cystic carcinoma (2 cases, malignant papilloma (2 cases and squamous cell carcinoma (34 cases. The combined technique of CD 34-alcian blue safranin (ABS was used to identify microvessel and mast cell density, which was quantified by the hot spot method. A significant correlation was found between both mast cell and microvascular density, and G1/G2 histological grade (p=0.002 and p=0.004, respectively. Squamous cell carcinoma was significantly correlated with mast cell density (p=0.003, but not with microvascular density (p=0.454.

    2015-01-01

    Full Text Available Myeloproliferative neoplasms (essential thrombocythemia, ET; polycythemia vera, PV; myelofibrosis, MF are monoclonal malignancies associated with genomic instability, dysregulated signaling pathways, and subsequent overproduction of inflammatory markers. Acknowledged for their debilitating symptom profiles, recent investigations have aimed to determine the identity of these markers, the upstream sources stimulating their development, their prevalence within the MPN population, and the role they play in symptom development. Creation of dedicated Patient Reported Outcome (PRO tools, in combination with expanded access to cytokine analysis technology, has resulted in a surge of investigations evaluating the potential associations between symptoms and inflammation. Emerging data demonstrates clear relationships between individual MPN symptoms (fatigue, abdominal complaints, microvascular symptoms, and constitutional symptoms and cytokines, particularly IL-1, IL-6, IL-8, and TNF-α. Information is also compiling on the role symptoms paradoxically play in the development of cytokines, as in the case of fatigue-driven sedentary lifestyles. In this paper, we explore the symptoms inherent to the MPN disorders and the potential role inflammation plays in their development.

  12. Defining the Thrombotic Risk in Patients with Myeloproliferative Neoplasms

    Directory of Open Access Journals (Sweden)

    Fabrizio Vianello

    2011-01-01

    Full Text Available Polycythemia vera (PV and essential thrombocythemia (ET are two Philadelphia-negative myeloproliferative neoplasms (MPN associated with an acquired mutation in the JAK2 tyrosine kinase gene. There is a rare incidence of progression to myelofibrosis and myeloid metaplasia in both disorders, which may or may not precede transformation to acute myeloid leukemia, but thrombosis is the main cause of morbidity and mortality. The pathophysiology of thrombosis in patients with MPN is complex. Traditionally, abnormalities of platelet number and function have been claimed as the main players, but increased dynamic interactions between platelets, leukocytes, and the endothelium do probably represent a fundamental interplay in generating a thrombophilic state. In addition, endothelial dysfunction, a well-known risk factor for vascular disease, may play a role in the thrombotic risk of patients with PV and ET. The identification of plasma markers translating the hemostatic imbalance in patients with PV and ET would be extremely helpful in order to define the subgroup of patients with a significant clinical risk of thrombosis.

  13. Cytokine Regulation of Microenvironmental Cells in Myeloproliferative Neoplasms

    Directory of Open Access Journals (Sweden)

    Gregor Hoermann

    2015-01-01

    Full Text Available The term myeloproliferative neoplasms (MPN refers to a heterogeneous group of diseases including not only polycythemia vera (PV, essential thrombocythemia (ET, and primary myelofibrosis (PMF, but also chronic myeloid leukemia (CML, and systemic mastocytosis (SM. Despite the clinical and biological differences between these diseases, common pathophysiological mechanisms have been identified in MPN. First, aberrant tyrosine kinase signaling due to somatic mutations in certain driver genes is common to these MPN. Second, alterations of the bone marrow microenvironment are found in all MPN types and have been implicated in the pathogenesis of the diseases. Finally, elevated levels of proinflammatory and microenvironment-regulating cytokines are commonly found in all MPN-variants. In this paper, we review the effects of MPN-related oncogenes on cytokine expression and release and describe common as well as distinct pathogenetic mechanisms underlying microenvironmental changes in various MPN. Furthermore, targeting of the microenvironment in MPN is discussed. Such novel therapies may enhance the efficacy and may overcome resistance to established tyrosine kinase inhibitor treatment in these patients. Nevertheless, additional basic studies on the complex interplay of neoplastic and stromal cells are required in order to optimize targeting strategies and to translate these concepts into clinical application.

    1994-05-01

    Trisomy 19 was found as the sole chromosomal aberration in three hematologic malignancies: one chronic myelomonocytic leukemia and two cases of of immunophenotypically immature acute myeloid leukemia (AML). A compilation of previously published hematologic neoplasms with +19 as the only change reveals that this anomaly is strongly associated with myeloid malignancies; 25 of 31 cases have been myelodysplastic syndromes (MDS) or AML. Eight of the 11 MDS cases have been either refractory anemia (RA) or RA with excess of blasts, and four of the 14 AML cases have had preleukemic myelodysplastic cases phase, with the +19 accruing during the time of leukemic transformation. The AML cases have, in general, been either or early maturation arrest, i.e. undifferentiated or AML-M1/M2, or of myelomonocytic-monoblastic origin, i.e., AML-M4/M5. None of the MDS or AML cases with +19 had had a previous history of radio- or chemotherapy. We conclude that trisomy 19, as the sole anomaly, is a characteristic abnormality in de novo myeloid malignancies. No clinical features seem to characterize patients with +19 AML and MDS and the prognostic impact of the aberration remains to be elucidated.

    Few studies have evaluated the risk of postoperative colorectal neoplasms stratified by the nature of primary colorectal cancer (CRC). In this study, we revealed it on the basis of the microsatellite (MS) status of primary CRC. We retrospectively reviewed 338 patients with CRC and calculated the risk of neoplasms during postoperative surveillance colonoscopy in association with the MS status of primary CRC. A propensity score method was applied. We identified a higher incidence of metachronous rectal neoplasms after the resection of MS stable CRC than MS instable CRC (adjusted HR 5.74, p=0.04). We also observed a higher incidence of colorectal tubular adenoma in patients with MSS CRC (adjusted hazard ratio 7.09, pcolorectal cancer influenced the risk of postoperative colorectal neoplasms.

    Purpose: To evaluate renal function changes related to radiofrequency ablation (RFA) for the treatment of multifocal renal neoplasms. Methods: This is an institutional review board-approved, Health Insurance Portability and Accountability Act compliant retrospective study of all patients treated with computed tomography guided RFA for multifocal renal neoplasms at one institution. Fifty-seven subjects, mean age 70 (range 37-88) years, underwent RFA of 169 renal neoplasms (average size 2.0 cm). Subjects had between 2 and 8 (mean 2.96) neoplasms ablated. Estimated glomerular filtration rate (eGFR) was measured before and after RFA. Complications related to RFA were recorded. Results: eGFR decreased on average of 4.4 % per tumor treated and 6.7 % per ablation session (average 1.76 tumors treated per session). For subjects with the largest neoplasm measuring >3 cm, eGFR decreased an average of 14.5 % during the course of their treatment. If the largest neoplasm measured 2-3 cm, eGFR decreased an average of 7.7 %, and if the largest neoplasm measured <2 cm, eGFR decreased an average of 3.8 %. Subjects with reduced baseline renal function were more likely to have a greater decline in eGFR after RFA. There was a minor complication rate of 6.3 % (6 of 96 sessions), none of which required treatment, and a major complication rate of 4.2 % (4 of 96 sessions). Conclusion: RFA for the treatment of multifocal renal neoplasms results in mild decline of renal function.

    Purpose The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. Methods A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All of them underwent colonoscopy within 6 months after undergoing gastroscopy. Results The prevalence of colorectal neoplasms was significantly higher in the stomach cancer group (35.8%) than in the control group (17.9%) (P neoplasms were more prevalent in the patients with stomach cancer (odds ratio [OR], 3.10; 95% confidence interval [CI], 1.71 to 5.63). In particular, the difference in the prevalence of colorectal neoplasms was more prominent in the patients above 50 years old (OR, 3.54; 95% CI, 1.80 to 6.98). Conclusion The results showed that the synchronous prevalence of colorectal neoplasms was higher in patients with stomach cancer than in those without stomach cancer. Therefore, patients with stomach cancer should be regarded as a high-risk group for colorectal neoplasms, and colonoscopy should be recommended for screening. PMID:22102975

    Full Text Available Objective. To evaluate the impact of oral hygiene on the development of oropharyngeal malignancies.Subjects and methods. The data of a prospective study of dental health indicators were analyzed in 586 patients (there were 76.4 % men and 23.6 % women with oropharyngeal malignancies. In the examinees, the sites of oropharyngeal neoplasms were as follows: the tongue in 195 (33 % cases, mouth floor in 147 (25 %, oropharynx in 139 (24 %, maxilla in 36 (6 %, buccal mucosa in 21 (4 %, soft palate in 18 (3 %, retromolar area in 14 (2 %, mandibula in 12 (2 %, and nose in 4 (1 %. The patients, examination employed routine dental examinations, determination of oral hygiene index, CFE index (a sum of carious, filled, and extracted teeth, and assessment of a patient, s skill and desire to perform individual oral hygiene. The patient hygiene performance (PHP index (Podshadley, Haley, 1968 was used to estimate his/her baseline ability. The rates of initial visits made by patients with oropharyngeal tumors to physicians of different specialties were also analyzed.Results. In the patients with oropharyngeal malignancies, the CFE index was high and amounted to 15 ± 0.4 с with a preponderance of carious and extracted teeth in the pattern; the PHP index was 1.4 ± 0.1, which corresponded to a satisfactory index. Thus, among the comparison group patients, satisfactory oral cavity sanitation was noted in only 4.8 % of the patients having a sanitation certificate. Consequently, 95.2 % of the patients were unready for specialized treatment. Out of the examinees, 176 (30 % made an initial visit for complaints to a dentist, 155 (26.5 % to an oncologist, 107 (18.3 % to an ENT doctor, 103 (17.7 % to a local therapist, and 43 (7.5 % to a surgeon. The collected history data also revealed that 59.2 % of the patients had self-treatment before going to specialists (according to them. Self-treatment or treatment by a noncancer specialist was ascertained to take an average of

    Full Text Available BACKGROUND: Power morcellation has become a common technique for the minimally invasive resection of uterine leiomyomas. This technique is associated with dissemination of cellular material throughout the peritoneum. When morcellated uterine tumors are unexpectedly found to be leiomyosarcomas or tumors with atypical features (atypical leiomyoma, smooth muscle tumor of uncertain malignant potential, there may be significant clinical consequences. This study was undertaken to determine the frequency and clinical consequence of intraperitoneal dissemination of these neoplasms. METHODOLOGY/PRINCIPAL FINDINGS: From 2005-2010, 1091 instances of uterine morcellation were identified at BWH. Unexpected diagnoses of leiomyoma variants or atypical and malignant smooth muscle tumors occurred in 1.2% of cases using power morcellation for uterine masses clinically presumed to be "fibroids" over this period, including one endometrial stromal sarcoma (ESS, one cellular leiomyoma (CL, six atypical leiomyomas (AL, three smooth muscle tumor of uncertain malignant potential (STUMPs, and one leiomyosarcoma (LMS. The rate of unexpected sarcoma after the laparoscopic morcellation procedure was 0.09%, 9-fold higher than the rate currently quoted to patients during pre-procedure briefing, and this rate may increase over time as diagnostically challenging or under-sampled tumors manifest their biological potential. Furthermore, when examining follow-up laparoscopies, both from in-house and consultation cases, disseminated disease occurred in 64.3% of all tumors (zero of one ESS, one of one CL, zero of one AL, four of four STUMPs, and four of seven LMS. Only disseminated leiomyosarcoma, however, was associated with mortality. Procedures are proposed for pathologic evaluation of morcellation specimens and associated follow-up specimens. CONCLUSIONS/SIGNIFICANCE: While additional study is warranted, these data suggest uterine morcellation carries a risk of disseminating

    Imprint cytology is a method of studying cells by taking an imprint from the cut surface of a wedge biopsy specimen or from the resected margins of a surgical specimen. It is rapid, simple and fairly accurate. Exfoliative cytology is an offshoot from the imprint cytology where in cells obtained from the surface of ulcers, either by scrape or brush, are analyzed for the presence of malignant cells. We undertook this study to see the role of imprint/exfoliative cytology in the diagnosis of ulcerated skin neoplasm and to check the adequacy of resected margins intra-operatively. This was a prospective investigative study conducted from September 2003 to July 2005. All patients presenting to surgical clinic with ulcerated skin and soft tissue tumours were included in the study. A wedge biopsy obtained from the ulcer and imprint smears were taken from the cut surface. Exfoliative cytology was analyzed from the surface smears. Wedge biopsy specimen was sent for histopathological (HPE) examination. The cytology and HPE were analyzed by a separate pathologist. Imprint cytology was also used to check the adequacy of resected margins in case of wide excision. This was compared with final HPE. Total of 107 patients was included in the present study and 474 imprint smears were done, with an average of 4.43 slides per lesion. Out of 59 wide excision samples, 132 imprint smears were prepared for assessing resected margins accounting for an average of 2.24 slides per each excised lesion. On combining imprint cytology with exfoliative cytology the overall sensitivity, specificity and positive predictive value were 90.38 %, 100 % and 90.38 % respectively. Only one out of 59 cases had a positive resected margin which was not picked by imprint cytology. Imprint cytology can be used for rapid and accurate diagnosis of various skin malignancies. It can also be used to check the adequacy of the resected margin intraoperatively.

    Full Text Available BACKGROUND: Small intestinal neuroendocrine neoplasm (SI-NEN proliferation is quantified by Ki67 measurements which capture G1-G2M phases of the cell cycle. G0 and early G1 phases, typical of slow-growing cells, can be detected by minichromosome maintenance protein (MCM expression. We hypothesized that these replication licensing markers may provide clinically relevant information to augment Ki67 in low-grade neuroendocrine neoplasia. METHODS: Immunohistochemical staining (IHC, Western blot analysis, quantitative polymerase chain reaction, and copy number variations of MCM2, MCM3, and Ki67 were undertaken in SI-NENs (n = 22. MCM and Ki67 expression was compared by Kaplan-Meier survival analysis (tissue microarray, independent set [n = 55]. Forty-three pancreatic NENs and 14 normal tissues were included as controls. RESULTS: In SI-NENs, MCM2 (mean: 21.2%: range: 16%-25% and MCM3 (28.7%: 22%-34% were detected in significantly more cells than Ki67 (2.3%: 0%-7%, P < .01. MCM2 mRNA correlated with Ki67 IHC (P < .05. MCM3 protein expression was higher in metastases (38-fold than in normal small intestine (P = .06 and was largely absent in normal neuroendocrine cells. There was considerable variation at the MCM copy number level (0-4 copies. MCM3 expression in proliferating cells significantly predicted overall survival (P < .002. Combinations of Ki67 and MCM2/3 in algorithms differentiated low and higher proliferative lesions (overall survival: 12 vs 6.1 years, P = .06. MCM expression was not informative in pancreatic NENs. CONCLUSION: MCMs are expressed in a higher proportion of NEN cells than Ki67 in slow-growing small intestinal lesions and correlate with survival. Assessment can be used to augment Ki67 to improve prognostic classification in these low-grade tumors.

    Progress is reported in the preparation and testing of boron compounds for use as targets in the neutron capture therapy of neoplasms. The synthesis and structural confirmation of the disulfide, B 1 H 11 SSB 12 H 11 -4 is reported as well as a new structural model for its mono-oxidized derivative, B 12 H 11 SOSB 12 H 11 -4 , which showed useful tumor:blood concentration ratios in rats after three I. V. injections. The material, B 12 H 11 (SH) 2 -2 , was isolated and identified from impure Cs 2 B 12 H 11 SH. The former anion was shown to be responsible, in its oxidized form, for the excellent tumor uptake results shown by impure B 12 H 11 SH -2 in the past. As a consequence of this work, a borane polymer was synthesized which has shown extremely encouraging tumor uptake properties. The synthesis of this polymer depended on our production and characterization of the first stable thiyl radical at room temperature, B 12 H 11 -S: -2 . The retesting of certain phosphate boranes is reported. And a reagent, namely acetyl sulfenyl chloride, lSCOCH 3 , has been found which will produce B 12 H 11 SH -2 in a laboratory synthesis. The ability of sulfur derivatives of B 12 H 11 SH -2 to bind to proteins was examined, as was the blood distribution of two of these interesting boranes. The amount of non-protein bound borane was related to the rate of blood clearance of the borane in rats. Progress is also reported on dog irradiation experiments. (U.S.)

    Full Text Available Abstract Background CDC25 phosphatases are important regulators of the cell cycle. Their abnormal expression detected in a number of tumors implies that their dysregulation is involved in malignant transformation. However, the role of CDC25s in vulvar cancer is still unknown. To shed light on their roles in the pathogenesis and to clarify their prognostic values, expression of CDC25A, CDC25B and CDC25C in a large series of vulvar squamous cell carcinomas were examined. Methods Expression of CDC25A, CDC25B, CDC25C and phosphorylated (phospho-CDC25C (Ser216 were examined in 300 vulvar carcinomas using immunohistochemistry. Western blot analysis was utilized to demonstrate CDC25s expression in vulvar cancer cell lines. Kinase and phosphatase assays were performed to exclude cross reactivity among CDC25s isoform antibodies. Results High nuclear CDC25A and CDC25B expression were observed in 51% and 16% of the vulvar carcinomas, respectively, whereas high cytoplasmic CDC25C expression was seen in 63% of the cases. In cytoplasm, nucleus and cytoplasm/nucleus high phospho-CDC25C (Ser216 expression was identified in 50%, 70% and 77% of the carcinomas, respectively. High expression of CDC25s correlated significantly with malignant features, including poor differentiation and infiltration of vessel for CDC25B, high FIGO stage, presence of lymph node metastases, large tumor diameter, poor differentiation for CDC25C and high FIGO stage, large tumor diameter, deep invasion and poor differentiation for phospho-CDC25C (Ser216. In univariate analysis, high expression of phospho-CDC25C (Ser216 was correlated with poor disease-specific survival (p = 0.04. However, such an association was annulled in multivariate analysis. Conclusions Our results suggest that CDC25C and phospho-CDC25C (Ser216 play a crucial role and CDC25B a minor role in the pathogenesis and/or progression of vulvar carcinomas. CDC25B, CDC25C and phospho-CDC25C (Ser216 were associated with

    Full Text Available Abstract Background Regional lymph node (LN status is a well-known prognostic factor for vulvar carcinoma (VC patients. Although the reliable LN assessment in VC is crucial, it presents significant diagnostic problems. We aimed to identify specific mRNA markers of VC dissemination in the LN and to address the feasibility of predicting the risk of nodal recurrence by the patterns of gene expression. Methods Sentinel and inguinal LN samples from 20 patients who had undergone surgery for stage T1-3, N0-2, M0 primary vulvar squamous cell carcinoma were analyzed. Gene expression profiles were assessed in four metastatic [LN(+] and four histologically negative [LN(−] lymph node samples obtained from four VC patients, by the Affymetrix U133 Plus 2.0 gene expression microarrays. Of the set of genes of the highest expression in the metastatic LNs compared to LN(−, seven candidate marker genes were selected: PERP, S100A8, FABP5, SFN, CA12, JUP and CSTA, and the expression levels of these genes were further analyzed by the real-time reverse transcription polymerase chain reaction (qRT-PCR in 71 LN samples. Results All of the seven genes in question were significantly increased in LN(+ compared to LN(− samples. In the initial validation of the seven putative markers of metastatic LN, the Cox proportional hazard model pointed to SFN, CA12 and JUP expression to significantly relate to the time to groin recurrence in VC patients. Conclusions Our findings first provided evidence that SFN, CA12 and JUP have a potential of marker genes for the prediction of the groin recurrence LN in VC patients.

    Roberta Sandra da Silva Tanizawa

    Full Text Available Abstract Background: Secondary myeloid neoplasms comprise a group of diseases arising after chemotherapy, radiation, immunosuppressive therapy or from aplastic anemia. Few studies have addressed prognostic factors in these neoplasms. Method: Forty-two patients diagnosed from 1987 to 2008 with secondary myeloid neoplasms were retrospectively evaluated concerning clinical, biochemical, peripheral blood, bone marrow aspirate, biopsy, and immunohistochemistry and cytogenetic features at diagnosis as prognostic factors. The International Prognostic Scoring System was applied. Statistical analysis employed the Kaplan–Meier method, log-rank and Fisher's exact test. Results: Twenty-three patients (54.8% were male and the median age was 53.5 years (range: 4–88 years at diagnosis of secondary myeloid neoplasms. Previous diseases included hematologic malignancies, solid tumors, aplastic anemia, autoimmune diseases and conditions requiring solid organ transplantations. One third of patients (33% were submitted to chemotherapy alone, 2% to radiotherapy, 26% to both modalities and 28% to immunosuppressive agents. Five patients (11.9% had undergone autologous hematopoietic stem cell transplantation. The median latency between the primary disease and secondary myeloid neoplasms was 85 months (range: 23–221 months. Eight patients were submitted to allogeneic hematopoietic stem cell transplantation to treat secondary myeloid neoplasms. Important changes in bone marrow were detected mainly by biopsy, immunohistochemistry and cytogenetics. The presence of clusters of CD117+ cells and p53+ cells were associated with low survival. p53 was associated to a higher risk according to the International Prognostic Scoring System. High prevalence of clonal abnormalities (84.3% and thrombocytopenia (78.6% were independent factors for poor survival. Conclusion: This study demonstrated that cytogenetics, bone marrow biopsy and immunohistochemistry are very important

    Blastic plasmacytoid dendritic cell neoplasm is an aggressive hematologic malignancy with a poor prognosis. No consensus regarding optimal treatment modalities is currently available. Targeting the nuclear factor-kappa B pathway is considered a promising approach since blastic plasmacytoid dendritic cell neoplasm has been reported to exhibit constitutive activation of this pathway. Moreover, nuclear factor-kappa B inhibition in blastic plasmacytoid dendritic cell neoplasm cell lines, achieved using either an experimental specific inhibitor JSH23 or the clinical drug bortezomib, interferes in vitro with leukemic cell proliferation and survival. Here we extended these data by showing that primary blastic plasmacytoid dendritic cell neoplasm cells from seven patients were sensitive to bortezomib-induced cell death. We confirmed that bortezomib efficiently inhibits the phosphorylation of the RelA nuclear factor-kappa B subunit in blastic plasmacytoid dendritic cell neoplasm cell lines and primary cells from patients in vitro and in vivo in a mouse model. We then demonstrated that bortezomib can be associated with other drugs used in different chemotherapy regimens to improve its impact on leukemic cell death. Indeed, when primary blastic plasmacytoid dendritic cell neoplasm cells from a patient were grafted into mice, bortezomib treatment significantly increased the animals' survival, and was associated with a significant decrease of circulating leukemic cells and RelA nuclear factor-kappa B subunit expression. Overall, our results provide a rationale for the use of bortezomib in combination with other chemotherapy for the treatment of patients with blastic plasmacytoid dendritic cell neoplasm. Based on our data, a prospective clinical trial combining proteasome inhibitor with classical drugs could be envisaged. Copyright© Ferrata Storti Foundation.

    Objective: To investigate the CT and MRI features of intraductal papillary neoplasm of the bile duct (IPNB). Methods: Thirty eight patients with IPNB finally diagnosed by puncture biopsy or surgery were enrolled in this study. All the CT or MRI data were investigated retrospectively. Twenty one patients underwent CT examinations, 17 patients underwent MRI examinations. The features of IPNB including the distribution features of the nodules or masses, CT and MRI features of cholangiectasis, mucus were analyzed. The accuracy differences of CT and MRI for the preoperatively diagnosing mucus and tumor growing along mucous were compared by nonparametric test. Results: The lesions (including 5 patients with solitary lesions and 19 patients with multiple lesions) were located in intrahepatic bile duct in 24 patients, 3 patients occurred simultaneously in intrahepatic and portal bile duct, 2 lesions occurred in portal bile duct, 8 lesions occurred in common bile duct, the lesions of 1 patient occurred simultaneously in common bile duct, cystic duct and gallbladder. Seventeen and 11 patients appeared nodules locating in dilated bile duct on CT and MRI, respectively. Four and 5 patients appeared cystic lesions with multiple nodules of the liver on CT and MRI, respectively. Higher contrast enhancement on CT and MRI in arterial phase than that in portal vein and equilibrium phase were observed in 18 and 12 patients, respectively. Excluding the patients undergoing puncture, CT was better than MRI in evaluating whether the mucus was present, with the accuracies of 30.0% (6/20) and 6.3% (1/16) for CT and MRI, respectively (Z=2.58, P<0.05). CT was worse than MRI in preoperatively evaluating the features of tumor growing along mucous, with the accuracies of 77.8% (14/18) and 92.6% (13/14) for CT and MRI, respectively (Z=4.23, P<0.01). Conclusion: IPNB had the features of growing along mucous of the bile duct, nodule or mass in dilated bile duct and other features, CT and MRI are

    We investigated the feasibility of using ultrasound colonography (USC) to visualize the healthy colon and rectum and detect colorectal polyps. Eight healthy volunteers underwent USC after standard bowel preparation. The feasibility and image quality of USC in different segments were evaluated. Then, USC was conducted on eight patients with known colonic neoplasms using colonoscopy as the reference standard. For volunteers, USC examinations were successfully performed on four (50.0%) ascending, three (37.5%) transverse and eight (100%) descending colons, as well as all sigmoid colons and rectums. One of four (25.0%) ascending, two of eight (25.0%) descending and all sigmoid colons and rectums were well visualized and free of artifacts. For patients, colonoscopy revealed that eight patients had 17 neoplasms in the distal sigmoid colon and rectum, which included 3 lesions ≤5 mm, 3 lesions 6-9 mm and 11 lesions ≥10 mm. USC visualized 12 of 17 (70.6%) neoplasms. Lesion detection by USC was 0% (0/3), 33.3% (1/3) and 100% (11/11) for neoplasms ≤5, 6-9 mm and ≥10 mm in size. USC can visualize the sigmoid colon and rectum well and detect distal sigmoid and rectal neoplasms ≥10 mm in diameter. Copyright © 2017 World Federation for Ultrasound in Medicine & Biology.

    The role of Helicobacter pylori (H. pylori) in the development of colorectal neoplasm remains controversial. We examined the association between H. pylori infection and colorectal neoplasm in a large sample of healthy participants who underwent screening colonoscopy. A cross-sectional study of 8916 men, who participated in a regular health-screening examination that included an H. pylori-specific immunoglobulin G antibody test and colonoscopy, was conducted to evaluate the association between H. pylori and colorectal neoplasm. Multivariable analyses adjusted for age, body mass index, smoking status, alcohol intake, regular exercise, regular aspirin use, and family history of colorectal cancer showed that the odds ratio (OR) (95% confidence interval [CI]) for any adenoma and advanced neoplasm was 1.32 (1.07-1.61) and 1.90 (1.05-3.56) in participants with H. pylori infection and without H. pylori infection, respectively. The association persisted after further adjustment for inflammatory markers or metabolic variables including fasting blood glucose, triglycerides, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol. Regarding the location, a positive association was confined to cases with proximal adenomas and was observed similarly in all the evaluated subgroups. In a large-scale study, carefully controlled for confounding factors, involving asymptomatic participants without a history of colonoscopy, H. pylori infection was significantly associated with the risk of any colorectal adenoma and advanced colorectal neoplasm. Prospective studies are necessary to determine whether H. pylori eradication can reduce this risk. © 2017 John Wiley & Sons Ltd.

    Reports on childhood cancer survivors estimated cumulative probability of developing secondary neoplasms vary from 3,3% to 25% at 25 years from diagnosis, and the risk of developing another cancer to several times greater than in the general population. In our retrospective study, we have used the classification tree multivariate method on a group of 849 first cancer survivors, to identify childhood cancer patients with the greatest risk for development of secondary neoplasms. In observed group of patients, 34 develop secondary neoplasm after treatment of primary cancer. Analysis of parameters present at the treatment of first cancer, exposed two groups of patients at the special risk for secondary neoplasm. First are female patients treated for Hodgkin's disease at the age between 10 and 15 years, whose treatment included radiotherapy. Second group at special risk were male patients with acute lymphoblastic leukemia who were treated at the age between 4,6 and 6,6 years of age. The risk groups identified in our study are similar to the results of studies that used more conventional approaches. Usefulness of our approach in study of occurrence of second neoplasms should be confirmed in larger sample study, but user friendly presentation of results makes it attractive for further studies

    The aim of the study was to describe the (a) symptom experience of women with vulvar intraepithelial neoplasia and vulvar cancer (vulvar neoplasia) during the first week after hospital discharge, and (b) associations between age, type of disease, stage of disease, the extent of surgical treatment and symptom experience. This cross-sectional study was conducted in eight hospitals in Germany and Switzerland (Clinical Trial ID: NCT01300663). Symptom experience after surgical treatment in women with vulvar neoplasia was measured with our newly developed WOMAN-PRO instrument. Outpatients (n=65) rated 31 items. We used descriptive statistics and regression analysis. The average number of symptoms reported per patient was 20.2 (SD 5.77) with a range of 5 to 31 symptoms. The three most prevalent wound-related symptoms were 'swelling' (n=56), 'drainage' (n=54) and 'pain' (n=52). The three most prevalent difficulties in daily life were 'sitting' (n=63), 'wearing clothes' (n=56) and 'carrying out my daily activities' (n=51). 'Tiredness' (n=62), 'insecurity' (n=54) and 'feeling that my body has changed' (n=50) were the three most prevalent psychosocial symptoms/issues. The most distressing symptoms were 'sitting' (Mean 2.03, SD 0.88), 'open spot (e.g. opening of skin or suture)' (Mean 1.91, SD 0.93), and 'carrying out my daily activities' (Mean 1.86, SD 0.87), which were on average reported as 'quite a bit' distressing. Negative associations were found between psychosocial symptom experience and age. WOMAN-PRO data showed a high symptom prevalence and distress, call for a comprehensive symptom assessment, and may allow identification of relevant areas in symptom management.

    Objective: To observe the effect of iodized oil on radiofrequency thermal ablation (RFA) of hepatic neoplasms by using a cluster array of ten separate electrodes. Methods: The patients were divided into 2 groups, group A with transcatheter hepatic artery embolization, group B without transcatheter hepatic artery embolization. All patients were undergone radiofrequency ablation of hepatic neoplasms. Results: The time of RFA for group A was (9 ± 2.1) minutes, showing the diameter of necrosis of (5.3 ± 1.4) cm. The time of RFA for group B was (16 ± 4. 6) minutes demonstrating the diameter of necrosis of (3.5 ± 1.8) cm (P<0.01). Conclusions: These findings suggest that radiofrequency thermal ablation of hepatic neoplasms with transcatheter hepatic artery embolization using iodized oil might improve the safety and synergic effect

    Full Text Available Serous cystadenomas are the most common cystic neoplasms of the pancreas. They may occur solely or coexist with other neoplasms. A 10 cm mass involving the body of the pancreas was observed in the computed tomography of a 61-year-old man with a previous history of bladder and prostate carcinoma. Ultrasonography and computed tomography of the mass demonstrated multiple small cysts associated with a central calcified scar. A distal pancreatectomy was performed. Pathological examination confirmed the diagnosis of serous microcystic adenoma. This is the first report of a serous cystadenoma of the pancreas with two metachronous neoplasms. This feature should be kept in mind during the diagnosis and evaluation of patients with serous cystadenoma.

    Specific components of the diet such as red and processed meat have been associated with the risk of developing colorectal cancer. However, evidence on the association of dietary patterns with colorectal neoplasms is sparse. The aim of this study was to analyze the association of dietary patterns with prevalence of advanced colorectal neoplasms among older adults in Germany. A cross-sectional study was conducted among participants of screening colonoscopy in Saarland, Germany, who were enrolled in the KolosSal study (Effektivität der Früherkennungs-Koloskopie: eine Saarland-weite Studie) from 2005 to 2013. Information on diet and lifestyle factors was obtained through questionnaires and colonoscopy results were extracted from physicians' reports. Associations of a priori defined dietary patterns (vegetarian or adapted versions of the Healthy Eating Index [HEI] and the Dietary Approaches to Stop Hypertension [DASH] index) with the risk of advanced colorectal neoplasms were assessed by multiple logistic regression analyses with comprehensive adjustment for potential confounders. A total of 14,309 participants were included (1561 with advanced colorectal neoplasms). Healthier eating behavior was associated with lower prevalence of advanced colorectal neoplasms in a dose-response manner. Adjusted odds ratios (95% confidence intervals) comparing the highest with the lowest categories of adapted HEI and DASH were 0.61 (0.50, 0.76) and 0.70 (0.55, 0.89), respectively. No significant associations were observed for a vegetarian eating pattern (adjusted OR 0.80 (0.55, 1.17)). Healthy dietary patterns, as described by a high HEI or DASH score, but not a vegetarian diet alone, are associated with reduced risk of advanced colorectal neoplasms. Copyright © 2018 Elsevier Inc.

    Full Text Available Malignant neoplasms of the pancreas are extremely rare in children and only represent a small percentage of pediatric cancer-related deaths. The paucity of cases reported in the literature, in addition to the lack of understanding of biologic behavior, has led to a lack of consensus concerning optimal management strategy. Presentation differs compared to adult counterparts and generally prognosis is improved even when lymph node metastases occur. Here we review the literature and report the case of a 10-year-old autistic female with a malignant nonfunctioning pancreatic endocrine neoplasm of the head of the pancreas successfully extirpated via pancreaticoduodenectomy.

    Full Text Available A neoplasia intra-epitelial vulvar grau III (NIV III se manifesta de modo visível, portanto, acessível à biópsia e, por conseguinte, ao diagnóstico histológico. Há duas formas precursoras do câncer vulvar: a NIV associada ao papiloma vírus humano (HPV e a NIV associada ao líquen simples crônico, hiperplasia de células escamosas e líquen escleroso, não tratados. Porém, pode existir sobreposição das duas formas. O termo papulose bowenóide, apesar de ser desencorajado, define uma das formas clínicas da NIV, que se apresenta como lesões pigmentadas, verruciformes, papulares e múltiplas. A NIV III está associada com HPV em mais de 80% dos casos e em 40% das vezes, nota-se envolvimento perianal. O seu tratamento é muito difícil e pode ocorrer recorrência em qualquer tempo e por muitos anos. Embora não exista tratamento padrão definido, os trabalhos apontam para a cirurgia, respeitando margem de segurança, como o mais adequado.High-grade vulvar intraepithelial neoplasia (VIN III is a visible lesion; therefore, it is accessible to biopsy and thus, to a histological diagnosis. There are two forms of vulvar cancer precursors: VIN caused by human papillomavirus (HPV and VIN associated with untreated lichen simplex chronicus, squamous cell hyperplasia, and lichen sclerosus. There may be overlap of the two forms. The term bowenoid papulosis, although discouraged, identifics a clinical form of VIN III. Such lesion appears as pigmented, wart-like growths or papules. VIN III is associated with HPV in more than 80% of the cases, and there is perianal involvement in 40% of the times. Vulvar intraepithelial neoplasia is difficult to cure and relapses can occur at any time for many years. Although there is no defined standard treatment, studies point to surgery, respecting a free margin, as the most adequate one.

    Purpose: Positive surgical margins after radical vulvectomy for vulvar cancer portend a high risk for local relapse, which may be challenging to salvage. We assessed the impact of adjuvant radiation therapy (aRT) on overall survival (OS) and the dose-response relationship using the National Cancer Data Base. Methods and Materials: Patients with vulvar squamous cell carcinoma who underwent initial extirpative surgery with positive margins from 1998 to 2012 were included. Factors associated with aRT and specific dose levels were analyzed using logistic regression. Log-rank and multivariable Cox proportional hazards modeling were used for OS analysis. Results: We identified 3075 patients with a median age of 66 years (range, 22-90 years); the median follow-up time was 36.4 months (interquartile range [IQR] 15.4-71.0 months). Stage IA/B disease represented 41.2% of the cohort. Sixty-three percent underwent lymph node assessment, with a 45% positivity rate. In total, 1035 patients (35.3%) received aRT, with a median dose of 54.0 Gy (IQR 48.6-60.0 Gy). The 3-year OS improved from 58.5% to 67.4% with aRT (P<.001). On multivariable analysis, age, Charlson-Deyo score ≥1, stage ≥II, tumors ≥4 cm, no aRT, and adverse nodal characteristics led to inferior survival. Dose of aRT was positively associated with OS as a continuous variable on univariate analysis (P<.001). The unadjusted 3-year OS for dose subsets 30.0 to 45.0 Gy, 45.1 to 53.9 Gy, 54.0 to 59.9 Gy, and ≥60 Gy was 54.3%, 55.7%, 70.1%, and 65.3%, respectively (P<.001). Multivariable analysis using a 4-month conditional landmark revealed that the greatest mortality reduction occurred in cumulative doses ≥54 Gy: 45.1 to 53.9 Gy (hazard ratio [HR] 0.94, P=.373), 54.0 to 59.9 Gy (HR 0.75, P=.024), ≥60 Gy (HR 0.71, P=.015). No survival benefit was seen with ≥60 Gy compared with 54.0 to 59.9 Gy (HR 0.95, P=.779). Conclusions: Patients with vulvar squamous cell carcinoma and positive surgical

    Persistent genital arousal disorder (PGAD) is an understudied condition characterized by unwanted physiologic genital arousal in the absence of subjective sexual arousal. Markos and Dinsmore (Int J STD AIDS 2013;24:852-858) theorized that PGAD shares a number of similarities with vulvodynia (unexplained chronic vulvar pain [CVP]), including symptom characteristics and comorbidities. To compare medical histories, symptom characteristics, pain characteristics, and daily functioning among women with persistent genital pain (PGA) (n = 42), painful PGA (n = 37), and CVP (n = 42) symptoms. An online cross-sectional survey was conducted from October 2015 through April 2016. Self-report measures of symptoms, diagnosed medical conditions, pain characteristics (McGill Pain Questionnaire), catastrophizing (Pain Catastrophizing Scale), and daily functioning (Functional Status Questionnaire) were collected. All 3 groups reported similar medical diagnoses and high frequencies of other chronic pelvic pain conditions. Women in all 3 groups reported comparable ages at symptom onset and timing of symptom expression (ie, constant vs intermittent). Women in the 2 PGA groups reported significantly greater feelings of helplessness than women in the CVP group. Women in the painful PGA and CVP groups endorsed significantly more sensory terms to describe their symptoms compared with women in the PGA group, whereas women in the painful PGA group reported significantly more affective terms to describe their symptoms compared with women in the CVP group. Women in the 2 PGA groups reported that their symptoms interfered significantly with most areas of daily functioning. Given the similarities between PGA and CVP symptoms, women with PGA may benefit from similar assessment, treatment, and research approaches. Limitations of the present study include its sole use of self-report measures; the presence of PGA or CVP symptoms was not confirmed by clinical assessment. However, the anonymous

    We attempted to obtain synthesized three dimensional (3D) and MPR (Multi Planar Reconstruction) helical CT scans (3D-MPR-CT) of gastric neoplasm by using the air as a contrast medium, and we assessed the usefulness of 3D-MPR-CT gastroendoscopy in the diagnosis of gastric neoplasm. Five minutes before the scan, 20 mg Scopolamine Butylbromide (Buscopan) was injected intramuscularly to minimize gastric peristalsis. An effervescent agent (bubble-make granules) was fed to extend the stomach wall. Non-ionic contrast material (100 mL) was power injected immediately before the scan start. Axial images were obtained with an intersection gap of 5-mm, a 5-mm/sec table speed, and 1-mm reconstruction intervals. 3D-MPR-CT images were reconstructed from these images. In abdominal study, 3D-MPR-CT images enabled the visualization of neoplasm and its adjacent structures in versatile directions, including a view similar to endoscopic observation, proximal aspect of narrowing by tumor and also could get the information about invasive depth of gastric neoplasm. Reports on some clinical cases and the advantages and disadvantages of 3D-MPR-CT gastroendoscopy were discussed. (author)

    Full Text Available Abstract Metastases to the breast are unusual lesions that make up approximately 2% of all malignant mammary neoplasms and may mimic both benign and malignant primary neoplasms from a clinical point of view, as well as in imaging studies. Arriving at a correct diagnosis is therefore essential in order to establish appropriate management. We present three cases of metastatic neoplasms diagnosed through fine needle aspiration biopsy and immunocytochemistry. The cytological diagnoses were: medulloblastoma in an 18-year-old woman, melanoma in a 26-year-old man, and an exceptional case of ovarian sarcoma originating from a granulosa cell tumor with metastases to both breasts. A metastatic disease should be considered in the differential diagnosis of a palpable mass in the breast, especially if there is a history of an extramammary malignant neoplasm. Fine needle aspiration biopsy is the method of choice for the management of these cases. Whenever possible the exam of the material obtained should be compared to the previous biopsy, which is usually enough to arrive at a correct diagnosis, thus preventing unnecessary surgical procedures.

    Melanocytic neoplasms are common in dogs and frequently occur within the oral cavity or in haired skin. The behavior of melanocytic neoplasms is variable and depends on tumor location, size, and histopathologic features. This study compared cytopathology and histopathology of 32 lymph nodes from 27 dogs diagnosed with melanocytic neoplasms. Agreement between the original cytology report, cytology slide review, original histopathology report, and histopathology slide review was determined for each lymph node. A subset of lymph nodes was subjected to immunohistochemistry (Melan-A) and additional histochemical stains/techniques (Prussian blue, bleach) to assist in differentiation of melanocytes and melanophages. Agreement ranged from slight to fair for each of the variables evaluated with weighted kappa (κ w ) or kappa (κ) analysis (original cytology vs cytology review κ w = 0.24; original cytology vs original histopathology κ w = 0.007; original cytology vs histopathology review κ w = 0.23; cytology review vs original histopathology κ w = 0.008; cytology review vs histopathology review κ w = 0.006; and original histopathology vs histopathology review κ = 0.18). The diagnoses (metastatic, equivocal, or negative for metastasis) of the original report and slide review for both cytology and histopathology were not significantly correlated with survival in this population of patients. Overall, agreement between cytology and histopathology was poor even with a single clinical or anatomic pathologist performing slide review. Consensus between routine cytology and histopathology for staging of lymph nodes in patients with melanocytic neoplasms is poor and does not correlate with survival.

    Hematoxylin and eosin (H&E) staining of tissue samples is the standard approach in histopathology for imaging and diagnosing cancer. Recent reports have shown that multiphoton microscopy (MPM) provides better sample interface with single-cell resolution, which enhances traditional H&E staining and offers a powerful diagnostic tool with potential applications in oncology. The purpose of this study was to further expand the versatility of MPM by establishing the optical parameters required for imaging unstained histological sections of pancreatic neoplasms, thereby providing an efficient and environmentally sustainable alternative to H&E staining while improving the accuracy of pancreatic cancer diagnoses. We found that the high-resolution MPM images clearly distinguish between the structure of normal pancreatic tissues compared with pancreatic neoplasms in unstained histological sections, and discernable differences in tissue architecture and cell morphology between normal versus tumorigenic cells led to enhanced optical diagnosis of cancerous tissue. Moreover, quantitative assessment of the cytomorphological features visualized from MPM images showed significant differences in the nuclear-cytoplasmic ratios of pancreatic neoplasms compared with normal pancreas, as well as further distinguished pancreatic malignant tumors from benign tumors. These results indicate that the MPM could potentially serve as an optical tool for the diagnosis of pancreatic neoplasms in unstained histological sections.

    Full Text Available Penile and preputial neoplasia in horses occurs infrequently and represents diagnostic and therapeutic challenges. The present study was carried out on a total number of 21 equids (14 stallions and 7 donkeys suffered from different penile and preputial neoplasia. Diagnosis of neoplasms was based up on history of the case, clinical examination as well as histopathological evaluation. Animals with penile and preputial neoplasms were underwent local excision and partial phallectomy with a slightly modified version of the techniques described by William’s. The diagnosed neoplasms were penile and preputial squamous cell carcinomas (SCCs; ; sarcoid (; a-fibrosarcoma; and a melanoma. Local excision was curative in all cases except 5 stallions with SCCs. These stallions had extensive damage of the glans penis, free part of the penis and the inner lamina of the internal fold of the prepuce, and they underwent a partial phallectomy with successful outcome. Follow-up information was obtained by visit and telephone inquiries. In conclusion, penile and preputial neoplasms are commonly encountered in elderly male horses and SCCs are the most common type affecting male external genitalia. Partial phallectomy is effective for management of equine neoplasia if they are confined to the glans and body of the penis and there is no proximal spread or involvement to regional lymph nodes.

    In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

    Full Text Available Aim. Investigate the disruption of geniculocalcarine tract (GCT in different occipital neoplasm by diffusion tensor imaging (DTI. Methods. Thirty-two subjects (44.1 ± 3.6 years who had single occipital neoplasm (9 gliomas, 6 meningiomas, and 17 metastatic tumors with ipsilateral GCT involved and thirty healthy subjects (39.2 ± 3.3 years underwent conventional sequences scanning and diffusion tensor imaging by a 1.5T MR scanner. The diffusion-sensitive gradient direction is 13. Compare the fractional anisotropy (FA and mean diffusivity (MD values of healthy GCT with the corresponding values of GCT in peritumoral edema area. Perform diffusion tensor tractography (DTT on GCT by the line propagation technique in all subjects. Results. The FA values of GCT in peritumoral edema area decreased (P=0.001 while the MD values increased (P=0.002 when compared with healthy subjects. There was no difference in the FA values across tumor types (P=0.114 while the MD values of GCT in the metastatic tumor group were higher than the other groups (P=0.001. GCTs were infiltrated in all the 9 gliomas cases, with displacement in 2 cases and disruption in 7 cases. GCTs were displaced in 6 meningiomas cases. GCTs were displaced in all the 7 metastatic cases, with disruption in 7 cases. Conclusions. DTI represents valid markers for evaluating GCT’s disruption in occipital neoplasm. The disruption of GCT varies according to the properties of neoplasm.

    Colorectal neoplasm and coronary artery disease (CAD) share similar risk factors, and their co-occurrence may be associated. To investigate the prevalence of colorectal neoplasm in patients with CAD in a cross-sectional study and to identify the predisposing factors for the association of the 2 diseases. Patients in Hong Kong, China, were recruited for screening colonoscopy after undergoing coronary angiography for suspected CAD during November 2004 to June 2006. Presence of CAD (n = 206) was defined as at least 50% diameter stenosis in any 1 of the major coronary arteries; otherwise, patients were considered CAD-negative (n = 208). An age- and sex-matched control group was recruited from the general population (n = 207). Patients were excluded for use of aspirin or statins, personal history of colonic disease, or colonoscopy in the past 10 years. The prevalence of colorectal neoplasm in CAD-positive, CAD-negative, and general population participants was determined. Bivariate logistic regression was performed to study the association between colorectal neoplasm and CAD and to identify risk factors for the association of the 2 diseases after adjusting for age and sex. The prevalence of colorectal neoplasm in the CAD-positive, CAD-negative, and general population groups was 34.0%, 18.8%, and 20.8% (P < .001 by chi2 test), prevalence of advanced lesions was 18.4%, 8.7%, and 5.8% (P < .001), and prevalence of cancer was 4.4%, 0.5%, and 1.4% (P = .02), respectively. Fifty percent of the cancers in CAD-positive participants were early stage. After adjusting for age and sex, an association still existed between colorectal neoplasm and presence of CAD (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.25-2.70; P = .002) and between advanced lesions and presence of CAD (OR, 2.51; 95% CI, 1.43-4.35; P = .001). The metabolic syndrome (OR, 5.99; 95% CI, 1.43-27.94; P = .02) and history of smoking (OR, 4.74; 95% CI, 1.38-18.92; P = .02) were independent factors for the

    For over 150 years, pathologists have relied on histomorphology to classify and diagnose neoplasms. Their success has been stunning, permitting the accurate diagnosis of thousands of different types of neoplasms using only a microscope and a trained eye. In the past two decades, cancer genomics has challenged the supremacy of histomorphology by identifying genetic alterations shared by morphologically diverse tumors and by finding genetic features that distinguish subgroups of morphologically homogeneous tumors. The Developmental Lineage Classification and Taxonomy of Neoplasms groups neoplasms by their embryologic origin. The putative value of this classification is based on the expectation that tumors of a common developmental lineage will share common metabolic pathways and common responses to drugs that target these pathways. The purpose of this manuscript is to show that grouping tumors according to their developmental lineage can reconcile certain fundamental discrepancies resulting from morphologic and molecular approaches to neoplasm classification. In this study, six issues in tumor classification are described that exemplify the growing rift between morphologic and molecular approaches to tumor classification: 1) the morphologic separation between epithelial and non-epithelial tumors; 2) the grouping of tumors based on shared cellular functions; 3) the distinction between germ cell tumors and pluripotent tumors of non-germ cell origin; 4) the distinction between tumors that have lost their differentiation and tumors that arise from uncommitted stem cells; 5) the molecular properties shared by morphologically disparate tumors that have a common developmental lineage, and 6) the problem of re-classifying morphologically identical but clinically distinct subsets of tumors. The discussion of these issues in the context of describing different methods of tumor classification is intended to underscore the clinical value of a robust tumor classification. A

    Hepatic neoplasms can be the primary indication for hepatic transplantation. The tumors can also be incidentally identified in explanted livers. We explored the clinicopathologic features of hepatic neoplasms identified in explanted livers. All explanted livers resected between 2001 and 2006 were evaluated for the presence of neoplasms and their clinicopathologic features were examined. In 198 liver transplants, 15 neoplasms (15.3%) were identified. Patient ages ranged from 5 to 63 years (median, 56 years). The primary etiology of hepatic disease was hepatitis C virus in 12 cases, hepatitis B virus in 1 case, cryptogenic cirrhosis in 1 case and congenital hepatic fibrosis in 1 case. Serum alpha-fetoprotein was significantly elevated (>400 U/L) in only 2 cases. CA19-9 was not elevated in any of the cases. The tumors included hepatocellular carcinoma (HCC) in 13 cases, 1 case of cholangiocarcinoma and 1 case of combined HCC and hepatoblastoma. The tumors ranged in size from 0.5 to 5 cm (median 1.4 cm) and were multifocal in 5 of the cases (33%). Tissue alpha-fetoprotein expression was only seen in the cases associated with elevated serum levels. In our institution hepatic neoplasma are seen in more than 15% of explanted livers. They can be incidentally identified, are frequently not associated with elevated serum levels of alpha-fetoprotein and CA19-9, are commonly multifocal but small and are associated with good prognosis. Elevated serum alpha-fetoprotein, albeit specific, is not a very sensitive marker in the detection of hepatic neoplasms. (author)

    To report variable radiologic manifestastions and to accomplish detailed radiologic-pathologic correlation of solid and papillary epithelial neoplasm of the pancreas. In 23 patients with surgically confirmed solid and papillary epithelial neoplasm, retrospective examination of operative records, gross and micropathologic findings, and radiologic findings including US(n=17), CT(n=23), ERCP(n=9), MRI(n=3) were carried out. On the basis of pathologic findings, detailed analysis of radiologic findings of solid and papillary epithelial neoplasm was then performed. Most pancreatic solid and papillary epithelial neoplasms(n=17) were seen as a mass with heterogeneous internal density consisting of cystic change, hemorrhagic necrosis, and tumor tissue, although the mass con also be seen to be homogeneous(n=6). On gross specimens, a capsule which showed enhancement on the delayed phase of the enhanced CT scan was demonstrated in 22 cases. In was seen as an echogenic rim on the ultrasound images and a low signal rim on the MR images. Calcification of the mass was seen in ten cases, nine of which showed peripheral calcification along the tumor capsule ; five cases showed calcifications within the mass. On pathologic examination, ten cases had a single or multiple cystic appearance ; in seven of these cases, this appeared on CT scan. In addition to usual mixed internal density caused by hemorrhagic necrosis of the tumor, enhanced capsule and internal multicystic appearance on CT scan were other characteristics of pancreatic solid and papillary epithelial neoplasm. These could be useful findings in the radiologic approach and in the differential diagnosis of pancreatic masses

    Full Text Available Objectives. Endoscopic submucosal dissection (ESD is a promising technique to treat early colorectal neoplasms by facilitating en bloc resection without size limitations. Although ESD for early gastrointestinal epithelial neoplasms has been popular in Japan, clinical experience with colorectal ESD has been rarely reported in Taiwan. Methods. From March 2006 to December 2011, 92 consecutive patients with early colorectal neoplasms resected by ESD at Tri-Service General Hospital were included. ESD was performed for colorectal epithelial neoplasms with a noninvasive pit pattern which had the following criteria: (1 lesions difficult to remove en bloc with a snare, such as laterally spreading tumors-nongranular type (LST-NG ≧20 mm and laterally spreading tumors-granular type (LST-G ≧30 mm; (2 lesions with fibrosis or which had recurred after endoscopic mucosal resection with a nonlifting sign. Results. The mean age of the patients was 66.3±12.9 years, and the male-female ratio was 1.8 : 1. The mean tumor size was 37.2±17.9 mm. The en bloc resection rate was 90.2% and the R0 resection rate was 89.1%. Perforations during ESD occurred in 11 patients (12.0% and all of them were effectively treated by endoscopic closure with hemoclips. No delayed perforation or postoperative bleeding was recorded. There were no procedure-related morbidities or mortalities. Conclusion. ESD is an effective method for en bloc resection of large early colorectal neoplasms and those with a nonlifting sign. An endoscopic technique to close perforations is essential for colorectal ESD.

    Acromegaly is a chronic disease resulting from pathological oversecretion of growth hormone and subsequently insulin growth factor-1. Several complications of the disease have been reported, including cardiovascular diseases, respiratory disorders but also increased risk of benign and malignant neoplasms. The aim of the study was to evaluate the risk of malignant neoplasms in the patients with acromegaly in comparison with the control group. Medical documentation of acromegalic patients treated in one medical center between 2005 and 2016 has been analyzed. Results were compared with sex- and age-matched group of subjects with prolactinomas and hormonally inactive pituitary lesions hospitalized in the same department. Two hundred patients with acromegaly were included. Control group was composed of 145 patients. Any malignant neoplasm in anamnesis was present in 27 (13.5 %) patients with acromegaly and six (4.1 %) subjects from control group (p = 0.003). Thyroid cancer was present in 14 (7.0 %) patients with acromegaly and two (1.4 %) in control group (p = 0.02). Breast cancer was present in seven women (5.4 % of women) in acromegaly group but none of subjects in control group (p = 0.02). Colon cancer-4 (2.0 %) patients in acromegaly group and 0 in control group (p = 0.14). Malignant neoplasms are significantly more common in patients with acromegaly. Particularly, risk of thyroid cancer was increased over fivefold. Systematic screening for neoplastic diseases should be important part of follow-up in these patients. Further case-control studies are strongly indicated to evaluate which neoplasms are more common in acromegalic patients and what is the exact risk of malignancy.

    Purpose: To describe the clinical and CT imaging features of goblet cell carcinoid (GCC) neoplasm of the appendix. Methods and materials: A computer search of pathology and radiology records over a 19-year period at our two institutions was performed using the search string “goblet”. In the patients with appendiceal GCC neoplasms who had abdominopelvic CT, imaging findings were categorized, blinded to gross and surgical description, as: “Appendicitis”, “Prominent appendix without peri-appendiceal infiltration”, “Mass” or “Normal appendix”. The CT appearance was correlated with an accepted pathological classification of: low grade GCC, signet ring cell adenocarcinoma ex, and poorly differentiated adenocarcinoma ex GCC group. Results: Twenty-seven patients (age range, 28–80 years; mean age, 52 years; 15 female, 12 male) with pathology-proven appendiceal GCC neoplasm had CT scans that were reviewed. Patients presented with acute appendicitis (n = 12), abdominal pain not typical for appendicitis (n = 14) and incidental finding (n = 1). CT imaging showed 9 Appendicitis, 9 Prominent appendices without peri-appendiceal infiltration, 7 Masses and 2 Normal appendices. Appendicitis (8/9) usually correlated with typical low grade GCC on pathology. In contrast, the majority of Masses and Prominent Appendices without peri-appendiceal infiltration were pathologically confirmed to be signet ring cell adenocarcinoma ex GCC. Poorly differentiated adenocarcinoma ex GCC was seen in only a small minority of patients. Hyperattenuation of the appendiceal neoplasm was seen in a majority of cases. Conclusions: GCC neoplasm of the appendix should be considered in the differential diagnosis in patients with primary appendiceal malignancy. Our cases demonstrated close correlation between our predefined CT pattern and the pathological classification

    The chronic and relapsing nature of vulvar lichen sclerosus (VLS) represents a challenge for its long-term management after an effective treatment with topical corticosteroids. To compare the effect of topical vitamin E with that of an emollient in reducing the risk of VLS relapse over a 52-week maintenance treatment. 156 patients with VLS were enrolled in a 12-week active treatment phase on topical 0.1% mometasone furoate ointment once daily. Those who achieved disease remission entered a 52-week maintenance phase in which patients were randomized to apply either an emollient or topical vitamin E once daily. 80 patients entered the maintenance phase. At 52 weeks, for the vitamin E maintenance group, the cumulative crude relapse rate was 27.8% and the cumulative modified crude relapse rate was 55.6%. For the emollient maintenance group, the cumulative crude relapse rate was 22.7% and the cumulative modified crude relapse rate was 50.0%. The median time to relapse was 20 weeks for the vitamin E group and 18.7 weeks for the emollient group. Once VLS has been stabilized with topical corticosteroids, long-term treatment with both vitamin E and emollients may be considered in maintain LS remission.

    Italian participants in the European REVIVE survey reported that vaginal and vulvar atrophy (VVA) impaired various aspects of their lives, notably the ability to enjoy sex. The aim of the present study was to explore regional differences in knowledge, experiences, and treatment of VVA in the Italian REVIVE sample (n = 1000), which was analyzed according to region of residence. While many respondents were unfamiliar with the VVA condition, most could relate their VVA symptoms to the menopause. The rate of diagnosis of VVA was twice as high in Central Italy as in the North-East. For individual VVA symptoms, 25.4-41.6% of respondents judged that the symptom had worsened over time. There were no significant regional differences for symptoms in terms of reported rate, change in severity, impact on sexual activity, or health-care visits. Testosterone cream and OTC medication based on hyaluronic acid showed significant regional differences in lifetime rates of use. In Italy, there are modest regional differences in knowledge, diagnosis, and treatment of VVA, some of which may be explained by inter-regional differences in health care. Further efforts are needed to ensure that Italian women are properly informed about VVA and have access to appropriate health care and treatments.

    To study the occurrence and types of neoplasms developed by patients who underwent an orthotopic cardiac transplantation under the Program of Cardiac Transplantation of Escola Paulista de Medicina, Federal University of São Paulo. This is an observational study of 106 patients who underwent orthotopic cardiac transplantation from November 1986 to September 2002 and survived at least thirty days following the procedure. The triple immunosuppressive regimen given included cyclosporin A, azathioprine and a corticosteroid agent. Only two patients received OKT3 in addition to the regimen established. Mean follow-up was 61.4 months (ranging from two months to 192 months). Twenty-three patients (21.3%) developed neoplasms--56.5% of these were skin neoplasm, 30.1%, solid tumors, and 13.4% of post-transplant lymphoproliferative disease (PTLD). Mean interval between transplantation and diagnosis of neoplasm was: 54.9 months for skin neoplasm; 24.8 months for solid tumors and 70.3 months for PTLD. Malignant neoplasms are relatively common in the population studied. Skin cancer was the most common type compared to the other types of neoplasms. Solid tumors were more frequently diagnosed than the lymphoproliferative diseases in the population examined.

    Full Text Available In present study, the data of standardised death rates of malignant neoplasms per 100000 inhabitants in 31 European countries during 1994-2013 were used to analyze linear correlations between eight types of cancers in terms of induced death rates. The results showed that most pairs of cancers closely correlate to each other. The malignant neoplasm of cervix uteri (women and the malignant neoplasm of trachea, bronchus and lung correlate most closely (r=0.5915, followed by the malignant neoplasms (r=0.4832 of colon, rectosigmoid junction, rectum, anus and anal canal and lymphatic/haematopoietic tissue, the malignant neoplasms (r=-0.483 of stomach, and trachea, bronchus and lung, the malignant neoplasms (r=0.4605 of skin and prostate (men, the malignant neoplasms (r=0.4344 of colon, rectosigmoid junction, rectum, anus and anal canal and trachea, bronchus and lung, etc. These correlations are likely caused by common or adverse environmental, social, medical or even genetic / molecular factors.

    Objective: To investigate the CT spectral imaging features of pancreatic serous oligocystic adenoma and mucinous cystic neoplasms and to assess the value of spectral CT in differentiating between pancreatic serous oligocystic adenoma and mucinous cystic neoplasms. Methods: From Feb. 2010 to Dec. 2010, 27 patients with cystic neoplasms of the pancreas (group one with 15 serous oligocystic adenomas and group two with 12 mucinous cystic neoplasms) underwent dual-phase CT spectral imaging followed by surgery. Quantitative values (age, tumor size, CT value change as function of photon energy, effective-Z, iodine-water concentration, and calcium-water concentration) were compared with independent samples t test and Mann-Whitney test and non-quantitative parameters (gender, symptom, and tumor location) were compared with Chi-square test (Fisher exact). The parameters with significant differences between two groups were analyzed further and the performance of multiple parameters for joint differential diagnosis was evaluated with discriminant analysis. Results: Compared to patients with mucinous cystic neoplasms, patients with serous oligocystic adenoma had younger age, lower frequency of being symptomatic and smaller tumor size. The CT values on 40 keV to 60 keV (with 10 keV increment) in late arterial phase [(36±13) HU vs. (62±23) HU, (26±8) HU vs. (40±15) HU, and (19±6) HU vs. (27±10) HU respectively] and 40 keV to 50 keV (with 10 keV increment) in portal venous phase [(43±14) HU vs. (61±25) HU and (30±10) HU vs. (40±16) HU respectively], effective-Z (late arterial phase 7.80± 0.16 vs. 8.05±0.21, and portal venous phase 7.87±0.15 vs 8.02±0.22), concentration of calcium (water) [late arterial phase (5±3) g/L vs. (11±4) g/L, t=-3.836, P=0.001 and portal venous phase (7±3) g/L vs. (10±5) g/L, t=-2.071, P=0.049] and iodine (water) [late arterial phase (0.38±0.24) g/L vs. (0.78±0.32) g/L, t=-3.755, P=0.001 and portal venous phase (0.48± 0.24) g/L vs. (0

    Pancreatic neoplasms, including ductal adenocarcinoma, solid pseudopapillary neoplasm, pancreatic endocrine neoplasms, acinar cell carcinoma, and pancreatoblastoma, are associated with different genetic abnormalities. Hepatic adenomas with beta-catenin exon 3 mutation are associated with a high risk of malignancy. Hepatic adenoma with arginosuccinate synthetase 1 expression or sonic hedgehog mutations are associated with a risk of bleeding. Hepatocellular carcinoma and choangiocarcinoma display heterogeneity at both morphologic and molecular levels Cholangiocellular carcinoma is most commonly associated with IDH 1/2 mutations.

The intervention described was radiofrequency ablation (RF) which was applied with an innovative monopolar RF probe (1.2 mm Habib EUS-RFA catheter) placed through a 19 or 22 gauge fine needle aspiration (FNA) needle once FNA was performed in patients with a tumor in the head of the pancreas. The Habib™ EUS-RFA is a 1 Fr wire (0.33 mm, 0.013”) with a working length of 190 cm, which can be inserted through the biopsy channel of an echoendoscope. RF power is applied to the electrode at the end of the wire to coagulate tissue in the liver and pancreas. RESULTS: Eight patients [median age of 65 (range 27-82) years; 7 female and 1 male] were recruited in a prospective multicenter trial. Six had a pancreatic cystic neoplasm (four a mucinous cyst, one had intraductal papillary mucinous neoplasm and one a microcystic adenoma) and two had a neuroendocrine tumors (NET) in the head of pancreas. The mean size of the cystic neoplasm and NET were 36.5 mm (SD ± 17.9 mm) and 27.5 mm (SD ± 17.7 mm) respectively. The EUS-RFA was successfully completed in all cases. Among the 6 patients with a cystic neoplasm, post procedure imaging in 3-6 mo showed complete resolution of the cysts in 2 cases, whilst in three more there was a 48.4% reduction [mean pre RF 38.8 mm (SD ± 21.7 mm) vs mean post RF 20 mm (SD ± 17.1 mm)] in size. In regards to the NET patients, there was a change in vascularity and central necrosis after EUS-RFA. No major complications were observed within 48 h of the procedure. Two patients had mild abdominal pain that resolved within 3 d. CONCLUSION: EUS-RFA of pancreatic neoplasms with a novel monopolar RF probe was well tolerated in all cases. Our preliminary data suggest that the procedure is straightforward and safe. The

    Mucinous cystic neoplasm of the liver (MCN-L) and intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) are diagnoses that were classified by the World Health Organization in 2010 as mucin-producing bile duct tumors of the hepatobiliary system. The preoperative differential diagnosis between these two entities is difficult; the presence of a communication with the bile duct is usually considered as a typical sign of IPMN-B. However, the presence of an ovarian-like stroma (OLS) has been established to define the diagnosis of MCN-L. We present the case of a 33-year-old woman with a rapid progression of a cystic tumor of the liver. In 2 years, the lesion increased from 27 to 64 mm and a dilation of the left hepatic duct appeared. Percutaneous transhepatic drainage with a biopsy was performed. No malignant cells were found on biopsy. Because of the rapid progression of the cystic tumor and unclear malignant potential, left hemihepatectomy was performed. Even though tumor masses were present in the biliary duct, on the basis of the presence of OLS, histology finally confirmed MCN-L with intermediate-grade intraepithelial dysplasia to high-grade intraepithelial dysplasia. The patient is currently under oncologic follow-up with no signs of recurrence of the disease. We present a rare case where MCN-L caused a dilation of the left hepatic duct, a sign that is usually a characteristic of IPMN-B.

    Background The 14-3-3 family is comprised of highly conserved proteins that are functionally important in the maintenance of homeostasis. Their involvement with the cell cycle, their association with proto-oncogenes and oncogenes, and their abnormal expression in various tumors has linked this family of proteins to the etiology of human cancer. Mounting evidence now indicates that 14-3-3σ is a cancer suppressor gene but the roles of the other 14-3-3 isoforms and their interactions in tumorigenesis have not yet been elucidated. In our current study, we examined the expression of 14-3-3β, γ, ε, ζ, η and τ in a large series of vulvar squamous cell carcinomas to evaluate any clinical significance. Methods Tumor biopsies from 298 vulvar carcinomas were examined by immunohistochemistry for the expression of 14-3-3β, γ, ε, ζ, η and τ. Statistical analyses were employed to validate any associations between the expression of any 14-3-3 isoform and clinicopathologic variables for this disease. Results High cytoplasmic levels of 14-3-3β, γ, ζ, ε and η were observed in 79%, 58%, 50%, 86% and 54% of the vulvar carcinomas analyzed, respectively, whereas a low nuclear expression of 14-3-3τ was present in 80% of these cases. The elevated cytoplasmic expression of 14-3-3β, γ, ε, ζ and η was further found to be associated with advanced disease and aggressive features of these cancers. The overexpression of cytoplasmic 14-3-3β and ε significantly correlated with a poor disease-specific survival by univariate analysis (P = 0.007 and P = 0.04, respectively). The independent prognostic significance of these factors was confirmed by multivariate analysis (P = 0.007 and P = 0.009, respectively). Conclusions We reveal for the first time that the 14-3-3β, γ, ε, ζ, η and τ isoforms may be involved in the progression of vulvar carcinomas. Furthermore, our analyses show that high cytoplasmic levels of 14-3-3β and ε independently correlate with

    Interleukin (IL)-15 plays an important role in the survival of human natural killer (NK) cells. We investigated IL-2/15 signaling in NK cell neoplasms from five patients and in five cell lines (NK-92, KHYG-1, SNK-6, HANK1 and MOTN-1) compared to mature peripheral NK cells from 10 healthy subjects. Apoptosis of NK cell lines was prevented by addition of IL-15 in vitro. Blocking IL-2/15Rbeta on IL-2-stimulated NK-92 cells resulted in reduced expression of Bcl-X(L) and phosphorylated Stat5, which paralleled early apoptosis without altering Bcl-2 expression. These data add IL-2/15Rbeta to the list of factors important for the survival of NK cell neoplasms.

    Objective: To assess the clinical value of 99 Tc m (V)-Dmsa imaging in detecting the ovarian and the pelvic cavity neoplasms. Methods: 99 Tc m (V)-DMSA imaging was performed on 24 patients with diagnosed ovarian neoplasms which were pathologically confirmed after operation. Results: 14 of the 15 patients with malignant ovarian tumors had positive 99 Tc m (V)-DMSA scintigraphy. However, 7 of 9 cases with benign ovarian tumors had negative 99 Tc m (V)-DMSA scintigraphy. The sensitivity, specificity, positive predictive value, negative predictive value, false positive rate, false negative rate, and accuracy of 99 Tc m (V)-DMSA imaging for detecting malignant ovarian tumors were 93.33%, 77.78%, 87.50%, 87.50%, 14.29%, 6.67% and 87.50%, respectively. Conclusions: 99 Tc m (V)-DMSA imaging is of important value in detecting malignant and benign ovarian and pelvic tumors

    Full Text Available We report a 50-year-old woman with no relevant clinical history who presented with headache and loss of memory. Magnetic resonance imaging showed a left parieto-temporal mass with annular enhancement after contrast media administration, rendering a radiological diagnosis of high-grade astrocytic neoplasm. Tumour sampling was performed but the patient ultimately died as a result of disease. Microscopically, the lesion had areas of glioblastoma mixed with a benign mesenchymal constituent; the former showed hypercellularity, endothelial proliferation, high mitotic activity and necrosis, while the latter showed fascicles of long spindle cells surrounded by collagen and reticulin fibers. With approximately 40 previously reported cases, gliofibroma is a rare neoplasm defined as either glio-desmoplastic or glial/benign mesenchymal. As shown in our case, its prognosis is apparently determined by the degree of anaplasia of the glial component.

    A 64-year-old man was transferred to our hospital because of indigestion and jaundice. The initial abdominal CT and MRI revealed a 2.0 cm enhancing mass in the proximal common bile duct (CBD) with several enlarged lymph nodes. The mass was presumed to be a cholangiocarcinoma, and a CBD segmental resection and choledochojejunostomy was performed. However, the final diagnosis was that of a mixed endocrine-exocrine carcinoma, a high-grade neuroendocrine neoplasm. Seven months after the operation, a follow-up abdominal CT study revealed multiple small arterial enhancing nodules in both hepatic lobes. A sono-guided liver biopsy confirmed these as metastastic mixed endocrine-exocrine carcinoma. This case is unique in that the imaging study regarding the neuroendocrine neoplasm of biliary duct has not been previously reported.

    2017-05-01

    Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can exhibit a wide spectrum of macroscopic and microscopic appearances. This not only causes occasional difficulties for the reporting pathologist in distinguishing these tumours from other lesions, but is also relevant clinically. As evidence accumulates, it becomes clear that multiple macroscopic and histological features of these neoplasms are relevant to the risk for malignant transformation and, consequently, of prime importance for clinical patient management. The need for detailed reporting is therefore increasing. This review discusses the panoply of gross and microscopic features of IPMN as well as the recommendations from recent consensus meetings regarding the pathology reporting on this tumour entity. © 2016 John Wiley & Sons Ltd.

    Uptake of [ 3 H]2-deoxyglucose was studied in BALB/c mice with EMT-6 sarcoma, in Buffalo rats with Morris 7777 hepatoma, and in eight dogs with spontaneous neoplasms: five osteosarcomas and three diffuse lymphomas. High tumor-to-tissue ratios were observed for all tumor types studies. In rodents, peak levels of uptake occurred between 30 min and 1 hr, with a slow loss from the tumor of about 10% per hour thereafter. In dogs there was considerable variability in uptake, both between individuals and at different tumor sites within an individual. Necrotic tumor did not take up the radiotracer. Absolute uptakes, when normalized for body weight, were similar for spontaneous and transplanted neoplasms. These studies provide additional support for the concept that positron emission tomography can be used to obtain functional images of important metabolic processes of tumors, including glycolysis

    Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can be classified according to whether or not they are confined to the appendix. Although LAMNs are frequently confined to the appendix, they can also spread to the peritoneum and clinically progress as pseudomyxoma peritonei (i.e., mucinous ascites). Thus, the appropriate classification of appendiceal primary neoplasia is essential for prognosis and influences clinical management. In addition, the precise classification, management, and clinical outcome of patients with disseminated peritoneal disease remain controversial. Here, we report an unusual case of LAMN with pseudomyxoma peritonei that initially presented with mucinous and bloody vaginal discharge. Pathological evaluation revealed low-grade appendiceal mucinous neoplasm with secondary involvement of the peritoneum, ovaries, and endometrial surface. Therefore, LAMN should be considered in the differential diagnosis of mucinous vaginal discharge.

    The present study was conducted to assess whether cytology can help in rapid diagnosis of ovarian neoplasms and thus facilitate individualised treatment. A prospective investigation was performed on 30 cases of suspected ovarian neoplasms. Imprint smears were made intraperatively from fresh samples from various representative areas, and stained with Leishman Giemsa for air-dried smears, and with hematoxylin and eosin and Papanicolaou for alcohol-fixed smears. A rapid opinion regarding the benign or malignant nature of the lesion and the type of tumour was given. The overall sensitivity was 96.2%, specificity 75%, positive predictive value 96.3%, and diagnostic accuracy of 83.3%. Characteristic cytological patterns were noted in various epithelial and germ cell tumours. Imprint cytology can be used as an adjunct to histopathology for rapid and early diagnosis in the operation theatre, thus helping better management of patients.

    Hidradenocarcinomas are very rare malignant sweat gland tumors that possess an infiltrative and/or low metastatic potential. Here we describe an interesting case of hidradenoma on the fronto-parietal region of the scalp of an elderly female, part of which had developed carcinomatous changes, infiltrating up to the pericranium. She developed intense itching, pain, spontaneous ulceration and rapid increase in the size of the tumor correlating with the expression of malignant behavior of the neoplasm. An initial incision biopsy suggested features of benign poroid hidradenoma, while the histology from the excised tumor exhibited a fairly well circumscribed epithelial neoplasm in dermis consisting of interconnected nodules as well as differentiated ducts, the neoplastic cells showing mild pleomorphism of nuclei, mitotic figures and abundant pale cytoplasm. Clefts, sclerotic stroma and foci of necrosis en mass were also seen. The final diagnosis was a well differentiated and slow growing hidradenocarcinoma. The tumor recurred locally despite total excision.

    For 1950 - 80, 194 ovarian cancer cases were ascertained among the 70,030 females of the RERF Life Span Study (LSS-E85) sample, and 106 autopsied cases with benign ovarian neoplasms were ascertained among all 3,046 autopsies performed in the same sample. On the basis of microscopic review, 66 % of the cancer and 84 % of the benign tumor cases were classified by histological type. The age-adjusted ovarian cancer incidence rates showed a statistically significant increase with increased exposure dose, both in the entire exposed group (P 0.10). The distribution of histological types of both cancer and benign tumor of the ovary did not vary significantly with radiation dose. The data are consistent with the hypothesis that radiation injury of ovaries with secondary excess of gonadotrophic hormones are important causative factors in the development of ovarian neoplasms.

    Background Limited data on mortality from malignant lymphatic and hematopoietic neoplasms have been published for Serbia. Methods The study covered population of Serbia during the 1991–2010 period. Mortality trends were assessed using the joinpoint regression analysis. Results Trend for overall death rates from malignant lymphoid and haematopoietic neoplasms significantly decreased: by −2.16% per year from 1991 through 1998, and then significantly increased by +2.20% per year for the 1998–2010 period. The growth during the entire period was on average +0.8% per year (95% CI 0.3 to 1.3). Mortality was higher among males than among females in all age groups. According to the comparability test, mortality trends from malignant lymphoid and haematopoietic neoplasms in men and women were parallel (final selected model failed to reject parallelism, P = 0.232). Among younger Serbian population (0–44 years old) in both sexes: trends significantly declined in males for the entire period, while in females 15–44 years of age mortality rates significantly declined only from 2003 onwards. Mortality trend significantly increased in elderly in both genders (by +1.7% in males and +1.5% in females in the 60–69 age group, and +3.8% in males and +3.6% in females in the 70+ age group). According to the comparability test, mortality trend for Hodgkin's lymphoma differed significantly from mortality trends for all other types of malignant lymphoid and haematopoietic neoplasms (P<0.05). Conclusion Unfavourable mortality trend in Serbia requires targeted intervention for risk factors control, early diagnosis and modern therapy. PMID:25333862

    Thyroid cancer presents as nodules. Thyroid nodules are frequent, but only 5-30% are malignant. Fine needle aspiration biopsy (FNAB) is useful for initial evaluation; nevertheless, malignancy is uncertain when follicular neoplasm is reported. Some factors can be associated with malignancy. Therefore, we analyzed our follicular neoplasms in order to identify those factors associated with a higher risk of malignancy. We analyzed the clinical files of consecutive patients with cytological diagnoses of follicular neoplasm. From 1,005 cases of thyroid nodules, 121 were follicular neoplasms according to cytology. Of these, 75 were surgically treated. Definitive report showed 45 benign (60%) and 30 malignant (40%) cases. Benign cases included 29 goiters, 11 follicular adenomas, and 5 cases of thyroiditis. Malignant cases were comprised of 12 papillary carcinomas, 4 follicular carcinomas, 3 papillary carcinomas-follicular variant, 1 lymphoma, 1 teratoma, 5 medullary carcinomas, 2 insular carcinomas, 1 anaplastic carcinoma and 1 metastatic breast carcinoma. Tumor size of benign lesions was 3.43 ± 2.04 cm, and 4.67 ± 2.78 (p = 0.049) for malignant lesions. Age was 46.95 ± 15.39 years for benign lesions and 48.67 ± 17.28 for malignant lesions (p = 0.66). Fifty percent of males showed malignancy vs. 37.7% of females (p < 0.005). Our results suggest that size and gender, but not age, are associated with cytological pattern. Ultrasonographic characteristics may be useful discriminating patients with a higher risk of malignancy. FNAB is a useful tool for initial evaluation of thyroid nodules, but clinical evaluation can enhance predictive value.

    1987-11-01

    In a retrospective study of 71 primary ovarian tumors in the dog, epithelial tumors (46%) were more common than sex cord stromal (34%) and germ cell tumors (20%). There were more adenocarcinomas (64%) than adenomas. Sex cord stromal tumors were equally divided into Sertoli-Leydig (12/24) and granulosa cell tumors (12/24). There were equal numbers (7/14) of dysgerminomas and teratomas among the germ cell tumors. Most teratomas (6/7) were malignant. Most granulosa cell tumors were solid; two were mostly cystic. Patterns included sheets of round and ovoid to spindle-shaped cells separated by thin, fibrovascular stroma; neoplastic cells formed rosettes or Call-Exner bodies. In some areas, neoplastic cells were in cords or columns and formed cyst-like structures. Four granulosa cell tumors were macrofollicular, having cysts lined with granulosa cells. Median ages of dogs with different ovarian neoplasms were similar; all were more than 10 years old, except the dogs with teratoma (mean age, 4 years). Most neoplasms were unilateral (84%), except the Sertoli-Leydig cell tumors, many of which were bilateral (36%). Size of ovarian neoplasms varied (2 cm3 to 15,000 cm3). Twenty-nine percent of neoplasms metastasized; adenocarcinomas (48%) and malignant teratomas (50%) had the highest rates, and distant metastasis was more common in malignant teratoma. Endometrial hyperplasia was in 67% of the dogs; it was most common in dogs with sex cord stromal tumors (95%). Uterine malignancy was not seen in dogs with granulosa cell tumors, although hyperplasia endometrium was in all dogs with this tumor. Cysts in the contralateral ovaries were most common in dogs with sex cord stromal tumors.

  8. Radiation-Induced Neoplasms in Beagles after Administrations of {sup 90}Sr and {sup 226}Ra

    The comparative carcinogenic efficiency of two bone-seeking radionuclides is under study in a colony of several hundred beagles. The toxicity of internally deposited alpha emitters ({sup 226}Ra and its daughters) and of beta irradiation ({sup 90}Sr) at comparable dosage rates indicates marked differences in site of appearance and mode of action in litters studied up to 7 years of age. Radiation carcinogenesis in beagles exposed to {sup 90}Sr daily from midgestation to adulthood (1.5 yr) is at present confined to dogs fed 4 {mu}Ci {sup 90}Sr/d or higher. The 20 cases constitute a spectrum of myeloproliferative disorders characterized by terminal anaemias, and ranging from myeloid metaplasia to granulocytic leukaemia. Continuous high-level {sup 90}Sr irradiation to bone and marrow from early life onward causes a thickened hypocellular bone ('pachyostosis'), some instances of myelofibrosis, and persistent mild leukopenia on which the final spectrum of terminal disoideis is superimposed. In contrast, up to 100 {mu}Cl {sup 226}Ra given intravenously (8 equally spaced injections at 14 to 18 months of age) to young adults is not a potent marrow cell carcinogen. The higher LET, shorter-range alpha particles are efficient in inducing bone cancers (14 cases) and skeletal lesions similar to those documented in watch-dial luminizers exposed to {sup 226}Ra in the early 1900's. The incidence of haematopoietic and skeletal neoplasms observed is dose-rate related, and the morphologic characteristics have several analogues in human cancer. The use of identically treated litters rather than individuals affords additional opportunity to study possible familial factors in the distribution of the neoplasms. Pathogenic evaluation at this juncture strongly indicates that continued bone and marrow irradiation in early life is more likely to induce haematopoietic neoplasms than is skeletal irradiation starting in young adulthood, which induces osseous neoplasms.

    Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can be classified according to whether or not they are confined to the appendix. Although LAMNs are frequently confined to the appendix, they can also spread to the peritoneum and clinically progress as pseudomyxoma peritonei (i.e., mucinous ascit...

    A variety of benign and malignant non-squamous cell neoplasms may affect the larynx. Most of these uncommon laryngeal neoplasms are located beneath an intact mucosa, making diagnosis difficult with endoscopy alone, and sampling errors may occur if only traditional superficial biopsies are performed. In some laryngeal neoplasms, radiologic evaluation allows the correct diagnosis. Hemangiomas have very high signal intensity at T2-weighted magnetic resonance (MR) imaging and strong enhancement at both computed tomography (CT) and MR imaging after administration of contrast material. Phleboliths, which are pathognomonic for hemangiomas, are easily identified at CT. Chondrogenic tumors typically manifest with coarse or stippled calcifications at CT. Because of their high water content, chondrogenic tumors have very high signal intensity on T2-weighted MR images, whereas only moderate enhancement is observed after administration of contrast material. Lipomas typically manifest at both CT and MR imaging as homogeneous nonenhancing lesions. They are isoattenuating to subcutaneous fat at CT and isointense relative to subcutaneous fat with all MR pulse sequences. Metastases from renal adenocarcinoma typically demonstrate strong contrast enhancement and flow voids at MR imaging, and metastases from melanotic melanoma usually have high signal intensity on T1-weighted MR images and low signal intensity on T2-weighted images owing to the paramagnetic properties of melanin. Although radiologic findings are nonspecific in most other non-squamous cell neoplasms of the larynx (eg, Kaposi sarcoma, hematopoietic tumors, tumors of the minor salivary glands, metastases from amelanotic melanoma), cross-sectional imaging can play an important role in the diagnostic work-up of these unusual tumors by delineating the extent of submucosal tumor spread and directing the endoscopist to the appropriate site for the deep, transmucosal biopsies needed to establish the diagnosis. In addition, CT

    Evidence shows cruciferous vegetables exhibit chemoprotective properties, commonly attributed to their rich source of isothiocyanates. However, epidemiological data examining the association between cruciferous vegetable intake and colorectal neoplasms have been inconclusive. This meta-analysis examines the epidemiological evidence to characterize the association between cruciferous vegetable intake and risk of developing colorectal neoplasms. Thirty-three articles were included in the meta-analysis after a literature search of electronic databases. Subgroup analysis for individual cruciferae types (n = 8 studies) and GST polymorphism (n = 8 studies) were performed. Pooled adjusted odds ratios (ORs) comparing highest and lowest categories of dietary pattern scores were calculated. Results show a statistically significant inverse association between cruciferous vegetable intake and colon cancer [OR = 0.84; 95% confidence interval (CI): 0.72-0.98; P value heterogeneity colorectal (CRC) neoplasms (OR = 0.80; 95% CI: 0.65-0.99; P value heterogeneity = 0.02). Stratification by GST genotype reveals that the GSTT1 null genotype confers a reduction in CRC risk (OR = 0.78; 95% CI: 0.64-0.95; P value heterogeneity = 0.32). This study provides support to the hypothesis that cruciferous vegetable intake protects against cancer of the colon. This study also demonstrates the significance of gene-diet interactions and the importance of assessing individual cruciferous vegetables.

  15. Positron imaging feasibility studies: characteristics of [3H]thymidine uptake in rodent and canine neoplasms

    1981-01-01

    Uptake [ 3 H]thymidine was studied in BALB/c mice with EMT-6 sarcoma, in Buffalo rats with Morris 7777 hepatoma, and in nine dogs with spontaneous neoplasms: four lymphomas, two osteosarcomas, two soft-tissue sarcomas, and a thyroid carcinoma. High tumor-to-tissue ratios were observed for all tumor types assayed, and absolute uptakes, when computed as percent dose per gram tumor normalized for body weight, were similar for transplanted and spontaneous tumors. In the rodent tumors, radiothymidine was retained for at least 3 hr in the tumor without appreciable loss. In canine neoplasms, although the highest uptakes were observed in cellular tumors with many mitotic figures, tumor uptake showed significant variability that did not correlate with any obvious histologic change, and thus may reflect true biologic differences in metabolism among tumors at different sites in the same animal. These studies provide additional experimental evidence that the ratios of neoplastic to normal tissue and the kinetics of thymidine uptake by tumors are suitable for positron emission tomography of neoplasms in small and large, animals, including both transplanted and spontaneous tumors

    Coccidioidomycosis is an endemic fungal infection in the southwestern of United States. Most infections are asymptomatic or manifest with mild respiratory complaints. Rare cases may cause extrapulmonary or disseminated disease. We report two cases of knee involvement that presented as isolated lytic lesions of the patella mimicking neoplasms. The first case, a 27 year-old immunocompetent male had progressive left anterior knee pain for four months. The second case was a 78 year-old male had left anterior knee pain for three months. Both of them had visited general physicians without conclusive diagnosis. A low attenuation lytic lesion in the patella was demonstrated on their image studies, and the initial radiologist’s interpretation was suggestive of a primary bony neoplasm. The patients were referred for orthopaedic oncology consultation. The first case had a past episode of pulmonary coccioidomycosis 2 years prior, while the second case had no previous coccioidal infection history but lived in an endemic area, the central valley of California. Surgical biopsy was performed in both cases due to diagnostic uncertainty. Final pathologic examination revealed large thick walled spherules filled with endospores establishing the final diagnosis of extrapulmonary coccidioidomycosis. Though history and laboratory findings are supportive, definitive diagnosis still depends on growth in culture or endospores identified on histology. We suggest that orthopaedic surgeons and radiologists keep in mind that chronic fungal infections can mimic osseous neoplasm by imaging

    We reviewed our clinical experiences of chemoradiotherapy (CRT) for esophageal cancer (EC) in 44 patients with multiple primary malignant neoplasms. Among them, 34 were accompanied with synchronous tumors, 8 were accompanied with antecedent tumors and 8 with subsequent tumors. The sites of primary malignant neoplasms were as follows; stomach 24 (43.6%), head and neck 17 (30.9%), colon and rectum 4 (7.3%). Among the 19 patients with synchronous cancer in the stomach, 6 patients underwent gastrectomy or endoscopic mucosal resection before CRT, and the others received definitive CRT as initial treatment. While 5 patients were alive without recurrence of EC and gastric cancer, more than half of the patients died of EC. Among 11 patients with head and neck cancer (HNC), 9 patients underwent surgery for HNC before CRT, because the clinical stages of the HNC was more progressive than that of EC. Only 3 patients achieved complete cure of both EC and HNC. The number of patients who developed subsequent tumors after CRT for EC was too small for us to draw definitive conclusions from our discussion, so further long-term follow-up and analysis based on large-scale surveys are required. Although CRT has become one of the standard treatments for EC, there is no treatment strategy for patients with both EC and other malignant primary neoplasms. Our results suggest that we should consider the curability of EC by CRT when we treat such patients. (author)

    Background/Aims Endoscopic submucosal dissection (ESD) has become accepted as a minimally invasive treatment for gastric neoplasms. However, the development of synchronous or metachronous gastric lesions after endoscopic resection has become a major problem. We investigated the characteristics of multiple gastric neoplasms in patients with early gastric cancer (EGC) or gastric adenoma after ESD. Methods In total, 512 patients with EGC or gastric adenoma who had undergone ESD between January 2008 and December 2011 participated in this study. The incidence of and factors associated with synchronous and metachronous gastric tumors were investigated in this retrospective study. Results In total, 66 patients (12.9%) had synchronous lesions, and 13 patients (2.5%) had metachronous lesions. Older (> 65 years) subjects had an increased risk of multiple gastric neoplasms (p = 0.012). About two-thirds of the multiple lesions were similar in macroscopic and histological type to the primary lesions. The median interval from the initial lesions to the diagnosis of metachronous lesions was 31 months. The annual incidence rate of metachronous lesions was approximately 3%. Conclusions We recommend careful follow-up in patients of advanced age (> 65 years) after initial ESD because multiple lesions could be detected in the remnant stomach. Annual surveillance might aid in the detection of metachronous lesions. Large-scale, multicenter, and longer prospective studies of appropriate surveillance programs are needed. PMID:24307844

    Mortality because of neoplasia was examined in Segment III dogs exposed to 0,20, or 100 R of 60 Co gamma radiation in prenatal and early postnatal life. During the inital 10 years of the experiment (through January 31, 1978) 20 dogs died or were killed because of neoplasia, 19 having been irradiated. Tumors in these 19 irradiated dogs included 5 malignant lymphomas, 8 carcinomas (2 of mammary origin, 2 of prostatic origin, and 1 each or oral mucosa, ovary, urinary bladder, and thyroid origin), 4 sarcomas (2 hemangiosarcomas, 1 fibrosarcoma and 1 mast cell sarcoma), 1 astrocytoma, and 1 hepatocellular adenoma. Neoplasms occurred in all irradiated groups except 8 dpc (20 and 100R) and 70 dpp (100R). Eleven neoplasms developed in dogs irradiated perinatally (55 dpc or 2 dpp) with 20 or 100R. Four of the tumors in the perinatally irradiated dogs were detected before 2 years of age. The earliest death was at 3 months, because of an astrocytoma. A single sham-irradiated dog died or a malignant tumor, a mammary carcinoma. Preliminary analyses point to three findings of particular interest: the preponderance of neoplasms causing death or euthanasia occurred in irradiated dogs, the unusual finding of four deaths because of neoplasia prior to 2 years of age in perinatally irradiated dogs, and the occurrence of five malignant lymphomas in this relatively small irradiated population

  20. The Utilization of Imaging Features in the Management of Intraductal Papillary Mucinous Neoplasms

    2014-01-01

    Full Text Available Intraductal papillary mucinous neoplasms (IPMNs represent a group of cystic pancreatic neoplasms with large range of clinical behaviours, ranging from low-grade dysplasia or borderline lesions to invasive carcinomas. They can be grouped into lesions originating from the main pancreatic duct, main duct IPMNs (MD-IPMNs, and lesions which arise from secondary branches of parenchyma, denominated branch-duct IPMNs (BD-IPMNs. Management of these cystic lesions is essentially based on clinical and radiological features. The latter have been very well described in the last fifteen years, with many studies published in literature showing the main radiological features of IPMNs. Currently, the goal of imaging modalities is to identify “high-risk stigmata” or “worrisome feature” in the evaluation of pancreatic cysts. Marked dilatation of the main duct (>1 cm, large size (3–5 cm, and intramural nodules have been associated with increased risk of degeneration. BD-IPMNs could be observed as microcystic or macrocystic in appearance, with or without communication with main duct. Their imaging features are frequently overlapped with cystic neoplasms. The risk of progression for secondary IPMNs is lower, and subsequently an imaging based follow-up is very often proposed for these lesions.

    Full Text Available Objective: To report on a series of 54 patients with pelvic neoplasms submitted to curative pelvic exenteration at a tertiary hospital and describe the results (morbidity, mortality, and long-term survival. Methods: The complete data of 54 patients submitted to pelvic exenteration between 1999 and 2007 were evaluated. Sixteen men and 38 women with a mean age of 65 years and median age of 66 years (36 to 77 were studied. Surgical procedures included total pelvic exenteration (n = 26, anterior pelvic exenteration(n = 5, and posterior pelvic exenteration (n = 23. Rresults: The mean operative time was 402 minutes (280 to 585. The average volume of intraoperative bleeding was 2,013 ml (300 to 5,800. Postoperative mortality was 5% (n = 3. The overall morbidity rate was 46%(n = 25. Histological evaluation demonstrated that 47 resections were R0 (87% while seven were R1 (13%. The overall survival rate in five years was 23.5% (n = 12. Cconclusions: Despite its aggressive nature and high morbidity, pelvic exenteration is still justified in locally advanced pelvic neoplasms or even in isolated pelvic recurrence, since it affords a greater long-term control of the neoplasm.

    Undifferentiated (embryonal) liver sarcoma (UELS) is a rare tumor that typically occurs in children. The association of UELS with neoplasm other than mesenchymal liver hamartoma is exceedingly rare. The aim of the study was to report 3 cases of UELS, 2 of them being interesting because of their association with another neoplasm, vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman. Besides, one of our cases of UELS, in a 58-year-old woman, is an extremely rare presentation of such a tumor in a middle-aged adult. The patient's clinical features, therapy, and pathologic results were reviewed; immunohistochemical analysis and, in 2 cases, electron microscopy were performed. In this study, all 3 patients were females aged 13, 13, and 58 years. Histopathologic evaluation of resected liver tumors confirmed the diagnosis of UELS in all of them. In 2 of the cases, metachronous occurrence of UELS with vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman is described. Careful clinical analysis, histologic studies, and immunohistochemistry are mandatory to distinguish UELS from other hepatic malignancies with similar or overlapping features and to exclude the possibility of other tumors that may be considered in the differential diagnosis. The association of UELS with another neoplasm is exceedingly rare. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available The review of literature for current methods of endoscopic treatment for colon epithelial neoplasms is represented. Such types of endoscopic interventions as loop electroresection, submucosal dissection, coagulation and destruction of tumors and combination of several options depending on efficiency of previous therapy is analyzed. Limitations of every method, its special aspects and possible complications are described. Special focus is on specifics of neoplasms for which selected methods may be the most effective. Thus, hot biopsy and destruction using high-energy laser is efficient for small flat neoplasms, endoscopic electroexcision – far small pedunculated lesions, and fragmentation is adequate for exophytic tumors more than 2.0 cm. Long-term results of endoscopic treatment, recurrence rates after different options are represented. The literature for photodynamic therapy consists mostly articles about development (on pre-clenecal stage of new photosensitizers which are effective for colon cancer, new methods of treatment including combination with hyperthermia in low-dose light irradiation etc. The literature data shows the prospectivity of subsequent developments in this field. 

  6. Diagnostic radiology for head and neck neoplasms with emphasis on computerized tomography

    Weber, A.L.; Manzione, J.V.

    1986-01-01

    The radiologic evaluation of head and neck neoplasms constitutes an important part in their diagnosis and treatment. The introduction of computerized tomography (CT) and the further development of this modality since 1972 have contributed significantly to the staging of these neoplasms. CT not only demonstrates soft tissue densities, but also bony structures, muscles, fascial planes, opacified vascular structures, and enlarged lymph nodes. CT, however, fails to differentiate the various histologic types of lesions in the majority of cases. Features such as size of the lesion, marginal definition, lytic bone destruction, sclerotic bony reaction, bony expansion, calcific densities, fat content, and obliteration of fascial planes are utilized to delimit the spectrum of diagnostic possibilities. Conventional films including tomography are also indicated as preliminary examinations in the investigation of head and neck neoplasms. They provide a survey of the abnormality in question and form the basis for special studies such as CT and angiography. They are often the first examination to demonstrate a lesion that may be suspected from the history and clinical examination. 13 refs.; 11 figs

    Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively ( P electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

    The third version of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine body neoplasms was published in 2013. The guidelines comprise nine chapters and nine algorithms. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. This revision was intended to collect up-to-date international evidence. The highlights of this revision are to (1) newly specify costs and conflicts of interest; (2) describe the clinical significance of pelvic lymph node dissection and para-aortic lymphadenectomy, including variant histologic types; (3) describe more clearly the indications for laparoscopic surgery as the standard treatment; (4) provide guidelines for post-treatment hormone replacement therapy; (5) clearly differentiate treatment of advanced or recurrent cancer between the initial treatment and the treatment carried out after the primary operation; (6) collectively describe fertility-sparing therapy for both atypical endometrial hyperplasia and endometrioid adenocarcinoma (corresponding to G1) and newly describe relapse therapy after fertility-preserving treatment; and (7) newly describe the treatment of trophoblastic disease. Overall, the objective of these guidelines is to clearly delineate the standard of care for uterine body neoplasms in Japan with the goal of ensuring a high standard of care for all Japanese women diagnosed with uterine body neoplasms.

    Computed tomographic(CT), ultrasonographic(US) findings of solid and papillary epithelial neoplasm of the pancreas were correlated with pathologic findings for the better understanding of this disease entity. A retrospective review of CT and US of 14 cases of solid and papillary epithelial neoplasm of the pancreas was carried out in terms of the margin, internal architecture, calcification and septation, and this was correlated with gross pathologic findings. CT and US findings were well defined round masses consisting of both solid and cystic components. Five cases were cystic, four cases were solid and five cases were mixed. Cystic portion of the tumor represented variable degree of hemorrhagic necrosis. Six cases contained foci of calcification, which were linear, marginal and amorphous. Marginal calcification interfered US examination of the mass in three cases. Internal septum was demonstrated in four cases on CT, one case on US and three cases on gross specimen. Our results indicate that calcification and internal septum were considered as a part of radiologic findings in solid and papillary epithelial neoplasm of the pancreas

    We aimed to evaluate the correlation between p16(ink4a)-overexpression and high risk (hr)HPV-DNA in vulvar squamous cell carcinoma (vSCC) tumors as well as the impact of both biomarkers on the prognosis of vSCC patients. PCR-detection of (hr)HPV-DNA and immunohistochemical staining for p16(ink4a) were conducted in 85 vSCC tumors. Survival analyses included the Kaplan-Meier method, log-rank test and Cox proportional hazards model. p16(ink4a)-overexpression and (hr)HPV-DNA were detected in 35 and 37 of the 85 tumors, respectively. Among the 35 p16(ink4a)-positive tumors, 10 lacked (hr)HPV-DNA (29 %). Among the 50 p16(ink4a)-negative tumors, (hr)HPV-DNA was detected in 12 cases (24 %). The median follow-up was 89.20 months (range 1.7-189.5 months). P16(ink4a)-overexpression, but not (hr)HPV-DNA positivity of the primary tumor, was correlated with prolonged overall survival (OS) (p = 0.009). P16(ink4a)-overexpression predicted a better response to radiotherapy (p overexpression (p = 0.022), and adjuvant RTX (p overexpression (HR 1-2.11, 95 % CI 1.13-3.95, p = 0.001) are independent prognostic factors. The discovered overlap suggests the use of p16(ink4a) in combination with HPV-DNA detection as an ancillary test for future research and clinical studies in vSCC. The prognostic and predictive value of p16(ink4a)-overexpression should be tested in larger cohort studies.

    Vulvar and vaginal atrophy (VVA) is a chronic medical condition experienced by many postmenopausal women. Symptoms include dyspareunia (pain with intercourse), vaginal dryness, and irritation and may affect sexual activities, relationships, and activities of daily life. The aim of this study is to characterize postmenopausal women's experience with and perception of VVA symptoms, interactions with healthcare professionals (HCPs), and available treatment options. An online survey was conducted in the United States in women from KnowledgePanel(®) , a 56,000-member probability-selected Internet panel projectable to the overall US population. Altogether, 3,046 postmenopausal women with VVA symptoms (the largest US cohort of recent surveys) responded to questions about their knowledge of VVA, impact of symptoms on their activities, communication with HCPs, and use of available treatments. Percent is calculated as the ratio of response over total responding for each question for all and stratified participants. The most common VVA symptoms were dryness (55% of participants), dyspareunia (44%), and irritation (37%). VVA symptoms affected enjoyment of sex in 59% of participants. Additionally, interference with sleep, general enjoyment of life, and temperament were reported by 24%, 23%, and 23% of participants, respectively. Few women attributed symptoms to menopause (24%) or hormonal changes (12%). Of all participants, 56% had ever discussed VVA symptoms with an HCP and 40% currently used VVA-specific topical treatments (vaginal over-the-counter [OTC] products [29%] and vaginal prescription therapies [11%]). Of those who had discussed symptoms with an HCP, 62% used OTC products. Insufficient symptom relief and inconvenience were cited as major limitations of OTC products and concerns about side effects and cancer risk limited use of topical vaginal prescription therapies. VVA symptoms are common in postmenopausal women. Significant barriers to treatment include lack of

    Full Text Available Background. Survivors of childhood leukemia have an increased risk of developing second malignant neoplasms and specific treatment factors such as alkylating agents, topoisomerase inhibitors and radiation have been associated with their occurrence. Genetic polymorphism in drug-metabolizing enzymes may result in impared detoxification of chemotherapeutics and may lead to increased risk for cancer.Methods. To test if polymorphism in glutathione S-transferases (GST genes is associated with occurrence of secondary malignant neoplasms, we compared GSTM1, GSTT1 and GSTP1 genotypes among 16 patients treated for childhood leukemia in whom second neoplasm occurred and matched the control group.Results. GSTM1 null genotype was found in 44% of patients with second neoplasms and in 50% in control group (p = 0.768, GSTT1 null genotype in 19% of cases and in 29% of controls (p = 0.729 and GSTP1 105 Ile/ile in 50% of cases and 37% of controls (p = 0.537. Differences in distribution of GST genotypes in patients with second neoplasms after childhood leukemia, compared to a matched control group of patients were not statistically significant.Conclusions. In our study we were not able to show relation between GST genotype and occurrence of second neoplasms after the childhood acute leukemia.

    The aim of this study was to conduct a meta-analysis of retrospective studies that investigated the association of preoperative C-reactive protein (CRP) levels with the overall survival (OS) of patients with bone neoplasms. A detailed literature search was performed in the Cochrane Library, Web of Science, Embase and PubMed databases up to August 28, 2017, for related research publications written in English. We extracted the data from these studies and combined the hazard ratios (HR) and 95% confidence intervals (CIs) to assess the correlation between CRP levels and OS in patients with bone neoplasms. Five studies with a total of 816 participants from several countries were enrolled in this current meta-analysis. In a pooled analysis of all the publications, increased serum CRP levels had an adverse prognostic effect on the overall survival of patients with bone neoplasms. However, the combined data showed no significant relationship between the level of CRP and OS in Asian patients (HR = 1.73; 95% CI: 0.86-3.49; P = 0.125). Similar trends were observed in patients with bone neoplasms when stratified by ethnicity, histology, metastasis and study sample size. The results of this meta-analysis suggest that increased CRP expression indicates a poorer prognosis in patients with bone neoplasms. More prospective studies are needed to confirm the prognostic significance of CRP levels in patients with bone neoplasms.

    We compared the ability of biennial fecal immunochemical testing (FIT) and one-time sigmoidoscopy to detect colon side-specific advanced neoplasms in a population-based, multicenter, nationwide, randomized controlled trial. We identified asymptomatic men and women, 50-69 years old, through community health registries and randomly assigned them to groups that received a single colonoscopy examination or biennial FIT. Sigmoidoscopy yield was simulated from results obtained from the colonoscopy group, according to the criteria proposed in the UK Flexible Sigmoidoscopy Trial for colonoscopy referral. Patients who underwent FIT and were found to have ≥75 ng hemoglobin/mL were referred for colonoscopy. Data were analyzed from 5059 subjects in the colonoscopy group and 10,507 in the FIT group. The main outcome was rate of detection of any advanced neoplasm proximal to the splenic flexure. Advanced neoplasms were detected in 317 subjects (6.3%) in the sigmoidoscopy simulation group compared with 288 (2.7%) in the FIT group (odds ratio for sigmoidoscopy, 2.29; 95% confidence interval, 1.93-2.70; P = .0001). Sigmoidoscopy also detected advanced distal neoplasia in a higher percentage of patients than FIT (odds ratio, 2.61; 95% confidence interval, 2.20-3.10; P = .0001). The methods did not differ significantly in identifying patients with advanced proximal neoplasms (odds ratio, 1.17; 95% confidence interval, 0.78-1.76; P = .44). This was probably due to the lower performance of both strategies in detecting patients with proximal lesions (sigmoidoscopy detected these in 19.1% of patients and FIT in 14.9% of patients) vs distal ones (sigmoidoscopy detected these in 86.8% of patients and FIT in 33.5% of patients). Sigmoidoscopy, but not FIT, detected proximal lesions in lower percentages of women (especially those 50-59 years old) than men. Sigmoidoscopy and FIT have similar limitations in detecting advanced proximal neoplasms, which depend on patients' characteristics

    Full Text Available Background Chordoid neoplasms refer to tumors appearing to have histological features of embryonic notochord, which is characterized by cords and lobules of neoplastic cells arranged within myxoid matrix. Because of radiological and histological similarities with myxoid matrix and overlapping immunohistochemical profile, chordoma, chordoid meningioma, chordoid glioma, and rare extraskeletal myxoid chondrosarcoma enter in the radiological and histological differential diagnosis at the site of skull base. However, there is always a great challenge for histopathologists to make an accurate diagnosis when encountering a chordoid neoplasm within or near the central nervous system. The aim of this study is to investigate and summarize the radiological, histological features and immunohistochemical profiles of chordoid neoplasms in skull base, and to find a judicious panel of immunostains to unquestionably help in diagnostically challenging cases. Methods A total of 23 cases of chordoid neoplasms in skull base, including 10 chordomas, 5 chordoid meningiomas, 3 chordoid gliomas and 5 extraskeletal myxoid chondrosarcomas, were collected from the First Affiliated Hospital, Sun Yat-sen University and Guangdong Tongjiang Hospital. MRI examination was performed on the patients before surgical treatment. Microscopical examination and immunohistochemical staining study using vimentin (Vim, pan-cytokeratin (PCK, epithelial membrane antigen (EMA, S?100 protein (S-100, glial fibrillary acidic protein (GFAP, D2-40, Galectin-3, CD3, CD20, Ki-67 were performed on the samples of cases. The clinicopathological data of the patients was also analyzed retrospectively. Results Most of chordomas were localized in the clivus with heterogeneous hyperintensity on T2WI scanning. The breakage of clivus was observed in most cases. Histologically, the tumor cells of chordoma exhibited bland nuclear features and some contained abundant vacuolated cytoplasm (the so

    Background There are no established guidelines for pathologic diagnosis/reporting of IPMNs. Design An international multidisciplinary group brought together by the Verona Pancreas Group in Italy-2013, was tasked to devise recommendations. Results 1) Crucial to rule out invasive carcinoma with extensive (if not complete) sampling. 2) Invasive component is to be documented in a full synoptic report including its size, type, grade, stage. 3) The term “minimally invasive” should be avoided; instead, invasion size with stage and substaging of T1 (1a, b, c; ≤0.5, >0.5–≤1, >1 cm), is to be documented. 4) Largest diameter of the invasion, not the distance from the nearest duct, is to be used. 5) A category of “indeterminate/(suspicious) for invasion” is acceptable for rare cases. 6) The term “malignant” IPMN should be avoided. 7) The highest grade of dysplasia in the non-invasive component is to be documented separately. 8) Lesion size is to be correlated with imaging findings in cysts with rupture. 9) The main duct diameter, and if possible, its involvement is to be documented; however, it is not required to provide main vs branch duct classification in the resected tumor. 10) Subtyping as gastric/intestinal/pancreatobiliary/oncocytic/mixed is of value. 11) Frozen section is to be performed highly selectively, with appreciation of its shortcomings. 12) These principles also apply to other similar tumoral intraepithelial neoplasms (mucinous cystic neoplasms, intra-ampullary, intra-biliary/cholecystic). Conclusion These recommendations will ensure proper communication of salient tumor characteristics to the management teams, accurate comparison of data between analyses, and development of more effective management algorithms.

    The incidence of neoplastic disease was determined by a mail survey of 2,872 young adults given x-ray treatments in infancy and of their 5,005 nonirradiated siblings. Newly diagnosed benign and malignant neoplasms appeared more frequently in the irradiated subjects than in their siblings or the age- and sex-matched general population of upstate New York. Only thyroid neoplasms occurred in sufficient numbers to permit statistical analysis for the effects on incidence of sex, age, and dose, and of being in a high-risk group (sub-group C). Thyroid cancers developed earlier in life than did benign neoplasms, especially in boys; benign goiters occurred after smaller doses, predominantly in females. Females had a greater risk of developing thyroid cancer than males--2.3 times for females of all ages and 5 times for young adults. Except for young adult females, there was no definite age effect. The risk of cancer (but not of benign goiter) was proportional to the thyroid dose, with a linear risk coefficient of 2.5/year/million people exposed to 1 rad for the entire irradiated population and 4.0 for subgroup C. The high risk of thyroid cancer in subgroup C may be the result of the high percentage of Jews, who had a 3.4-fold greater risk than non-Jews. Young adult Jewish females had a 17-fold increased risk. An incidental observation was an apparent increased incidence of asthma and rare diseases with abnormal immunologic features in the irradiated population. (auth)

    Obesity has been associated with increased risk for postoperative CSF leak in patients with benign cranial nerve tumors. Other measures of postoperative morbidity associated with obesity have not been well characterized. Patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013 with a diagnosis code of a benign neoplasm of a cranial nerve were included. The primary outcome of postoperative morbidity was analyzed as well as secondary outcomes of readmission and reoperation. The main covariate of interest was body mass index (BMI). A total of 561 patients underwent surgery for a benign cranial nerve neoplasm between 2007 and 2013. Readmission data, available for 2012-2013(n=353), revealed hydrocephalus, facial nerve injury, or CSF leak requiring readmission or reoperation occurred in 0.85%, 1.42%, and 3.12%, respectively. Composite morbidity included wound complications, infection, respiratory insufficiency, transfusion requirement, stroke, venous thromboembolism, coma and cardiac arrest. On multivariable analysis patients with class I (BMI 30-34.9) and II (BMI 35-39.9) obesity showed trends towards increasing return to operating room, though not significant, but there was no trend for composite complications in class I and II obesity patients. However, class III obesity, BMI≥40, was associated with increased odds of composite morbidity (OR 4.40, 95% CI 1.24-15.88) and return to the operating room (OR 5.97, 95% CI 1.20-29.6) relative to patients with a normal BMI, 18.5-25. Obesity is an independent and important risk factor for composite morbidity in resection of benign cranial nerve neoplasms, and as such, merits discussion during preoperative counseling.

    Beagle dogs were given whole-body exposure to 60 Co gamma radiation at one of six ages of pre- or postnatal life. Four-hundred and eighty dogs, 120 for each age at exposure, received 20 R at 8, 28 or 55 days postcoitus (dpc) or at 2 days postpartum (dpp). Similarity 480 dogs, in groups of 120, were exposed to 100 R at these same ages. Exposures of 100 R were also given to 118 dogs at 70 dpp and 231 dogs at 365 dpp. An additional 359 dogs were sham-irradiated. Mean values for each age at exposure ranged from 15.6 to 17.5 rads for 20 R exposures and from 80.8 to 88.3 rads for exposure to 100 R. Mortality due to neoplasia during the initial ten years of the experiment was examined. Twenty dogs died or were killed because of neoplasia, 19 having been irradiated. Tumours in these 19 irradiated dogs included five malignant lymphomas, eight carcinomas (two of mammary origin, two of prostatic origin, and one each of oral mucosa, ovary, urinary bladder, and thyroid origin), four sarcomas (two haemangiosarcomas, one fibrosarcoma and one mast cell sarcoma), one astrocytoma, and one hepatocellular adenoma. Neoplasms occurred in all irradiated groups except 8 dpc (20 and 100 R) and 70 dpp (100 R). Eleven neoplasms developed in dogs irradiated perinatally (55 dpc or 2 dpp) with 20 or 100 R. Four of the tumours in the perinatally irradiated dogs were detected before two years of age. The earliest death was at three months, due to an astrocytoma. Preliminary analyses point to findings of particular interest: (1) the preponderance of neoplasms causing death or euthanasia occurred in irradiated dogs; (2) the unusual finding of four deaths due to neoplasia before two years of age in perinatally irradiated dogs; and (3) the occurrence of five malignant lymphomas in this relatively small irradiated population

    Full Text Available BACKGROUND Ovarian tumours being second most common gynaecological cancer in India account for 30% of all cancers of female genital tract. Study conducted to determine relative frequencies of various histological types based on WHO classification and their age distribution with particular emphasis on surface epithelial tumours. This study is undertaken to find out the frequency of incidence of different histopathological subtypes with particular emphasis on surface epithelial tumours and age distribution of ovarian tumours in our institute located in coastal Andhra Pradesh. METHODS This is a retrospective study of 100 cases of ovarian neoplasms collected during a period of 3 years from June 2013 to May 2016 from the Department of Pathology, Katuri Medical College and Hospital, Chinakondrupadu, Guntur, A. P, India. The patients attending our hospital are mostly from rural areas around. Paraffin blocks of all 100 ovarian neoplasms retrieved. Complete clinical and radiological findings analysed from our records. RESULTS The tumours are grouped according to the nature of tumour whether benign or borderline or malignant according to cell of origin, histological subtyping, and age group. Surface epithelial tumours are the most common. Benign tumours outnumber the malignant tumours. Benign ovarian tumours showed a peak in 21-40 Yrs. age group and malignant in the age group of 41- 60 Yrs. Results of our study compared with other studies. CONCLUSION Because of the geographic location, poverty, and illiteracy, patients seek medical advice late. So, awareness among public by health education, passive surveillance, and community screening facility will be helpful in early detection of ovarian neoplasms.
