During the period 1931 to 1970, 50 cases of radiation-induced osteogenic sarcoma were seen at Memorial and James Ewing Hospitals. Twenty-two these had previously been described; present paper adds an additional 28 existing series reviews those factors related development neoplastic changes. In 35 patients, there was evidence preexisting bone pathology in form benign osseous growths. Fifteen patients soft-part visceral neoplasms, such as retinoblastoma, seminoma, breast carcinoma, involved...

The TNM classification (tumor-node-metastasis) was adopted by the American Joint Committee on Cancer and International Union against a decade ago to avoid heterogeneity of prognostic schemes used for differentiated thyroid cancers. To date, however, clinical data based this are lacking. We retrospectively evaluate prognosis 700 patients (208 men 492 women) with papillary (89%) follicular (11%) cancers according pathological (pTNM) staging system, treated over 25-yr period (1970–1995)....

<h3>AIM</h3> To evaluate the clinical features, treatment results, and recurrence rates in patients with either intraepithelial or invasive squamous cell carcinoma of conjunctiva. <h3>METHODS</h3> Retrospective analysis 60 cases (22 conjunctival 38 carcinomas) to determine patterns presentation, aetiological factors, results. The mean patient age was 64 years old. 70% were male. Patients treated a variety therapies, depending on degree tumour involvement; most frozen section controlled...

Both the association between lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC), prognostic significance of infiltrate in patients with malignancy, remain controversial. We examine above relationships by retrospectively reviewing our series treated for differentiated nonmedullary at University California-San Francisco over a 25-yr period (1970-1995). Of 631 complete data analysis, 128 (20.3%) showed concomitant histologic evidence LT 503 (79.7%) had no LT. Prognostic outcome...

<h3>AIMS</h3> Three issues were investigated in adult outpatients with orbital metastases. One, how accurate are current diagnostic methods? Two, what is the survival associated metastases? Three, did any clinical factors correlate prognosis this patient cohort? <h3>METHODS</h3> Retrospective analysis of patients metastases managed an ocular oncology unit. <h3>RESULTS</h3> 11 31 (35%) had no known primary malignancy at time diagnosis. In eight (26%) computed tomography and/or magnetic...

Fine-needle aspiration biopsy (FNAB) has been used with variable success as a diagnostic test for benign and malignant breast lesions. The goal of this study was to examine the effects training physicians in fine-needle sampling-technique on accuracy FNAB palpable masses. settings were private physicians' offices university clinics primary care physicians, surgeons, cytopathologists.We reviewed 1043 consecutive specimens obtained during 1 year (1992): 729 FNABs performed by formally trained...

Twelve patients with histologically proved sarcoma arising in fibrous dysplasia of bone (six monostotic, six polyostotic) are described. In five (Group I) the existence was known years before arose, and seven II) discovery both lesions concurrent. The average age Group I [See figure PDF file] fifteen when compared thirty-five II. only one instance could history previous radiotherapy be elicited. histological examination primary sarcomas revealed eight osteosarcomas, two chondrosarcomas,...

Nuclear magnetic resonance (NMR) images of live rats with sterile and pyogenic abscesses, hematomas, various implanted spontaneous neoplasms demonstrated good contrast differentiation between pathologic surrounding normal tissues. This was maximal when both the T1 T2 tissue relaxation times were used as criteria. Neoplasms have a broad range values may be confused abscesses or hematomas. Tissue rate constants (1/T1 1/T2) are mainly dependent on total water content, exception being fat, which...

In general, the sequences of radiofrequency and magnetic field gradients used to form nuclear resonance images are designed for a stationary object. Consequently, these produce different response when applied moving blood. These changes in signal permit visualization vessels can be measure their open area. addition, specific relaxation time signatures lesions may help identifying nature obstructions.

Between January 1, 1931, and 31, 1970, 121 patients were treated for chondrosarcoma of the pelvis proximal end femur. Of these patients, 113 with 152 operations met stated criteria used to study factors influencing survival rate. At time follow-up, forty alive seventy-three dead. living five had disease thirty-five showed no evidence disease—eleven more than fifteen years after their last surgical procedure. dead fifty-nine died from fourteen, other causes. The data analyzed sex, age,...

To evaluate the features on magnetic resonance (MR) images of malignant and nonmalignant retroperitoneal fibrosis (RPF) to assess usefulness MR imaging in differentiating two conditions, studies nine patients with RPF were retrospectively examined compared those eight RPF. Morphologic findings at similar for both conditions. The lesions were, however, heterogeneous six homogeneous all On T2-predominant images, showed high signal intensity, while low intensity. intensity T2 significantly...

Myxoma is a peculiar and rare bone tumor of the jaws. During last 50 years, 10 such cases were treated in Memorial-Sloan Kettering Cancer Center. Six mandible four maxilla. that period, 8,723 primary tumors this hospital. Although histologically benign, it has potentiality local invasion bone. Excision underlying whenever involved by should be done.

Abstract The National Cancer Institute (NCI) sponsored the NCI Thyroid Fine‐Needle Aspiration (FNA) State of Science Conference on October 22–23, 2007 in Bethesda, MD. 2‐day meeting was accompanied by a permanent informational website and several on‐line discussions between May 1 December 15, ( http://thyroidfna.cancer.gov ). This document summarizes indications for performing an FNA nodule discovered physical examination or imaging study; using ultrasound versus palpation guidance when...

Primary reticulum cell sarcoma of bone was found to have a relatively good prognosis in review 47 cases. It also that age, sex, or duration symptoms had nothing do with the prognosis. Although any statistical validity not obtained, large amount radiation therapy during short periods on whole seems treatment choice, and Coley's toxin may be combined it for better results, at least symptomatic improvement. Radiation local area should abandoned. The most important factor influencing is extent...

We retrospectively reviewed the cytology and immunohistology of vitreous specimens from nine patients with intraocular lymphoma (ocular reticulum cell sarcoma). A single biopsy specimen was not always adequate to establish diagnosis in this condition. Cytological evaluation more accurate than lymphocyte surface marker analysis differentiate uveitis. The immunological features these tumours indicate a heterogeneous group lymphomas.
