Fine-needle aspiration of primary osseous lesions: A cost effectiveness study

DIAGNOSTIC CYTOPATHOLOGY, Issue 4 2010
Lester J. Layfield M.D.
Abstract Fine-needle aspiration (FNA) is not widely used in the work-up of osseous lesions because of concerns regarding its high incidence of nondiagnostic specimens. Although several studies have shown that FNA is less expensive than surgical biopsy, the authors are aware of only one prior study evaluating the cost effectiveness of FNA, which includes the cost of incisional or core needle biopsies necessary to establish a diagnosis when the initial FNA was noncontributory. A computerized search of the pathology records of three medical centers was performed to obtain all FNAs of primary osseous lesions. For each FNA case, all subsequent core needle, incisional or excisional biopsies were recorded as was the result of the definitive operative procedure. The cost of obtaining the definitive diagnosis was calculated for each case including the cost of FNA, imaging guidance utilized, and cost of subsequent surgical biopsy when necessary. The cost of an alternate approach using only surgical biopsy was calculated. The average per patient costs of these two protocols were compared. A total of 165 primary bone tumors underwent FNA. One hundred six of these yielded a definitive cytologic diagnosis. In 59 cases, FNA yielded a result insufficient for definitive therapy necessitating surgical biopsy. FNA investigation of the 165 bone lesions cost 575,932 (average of 3,490 per patient). Surgical biopsy alone would have cost 5,760 per patient. FNA resulted in a cost savings of 2,215 per patient.

Abstract Purpose Management of squamous cell carcinoma of undetermined primary tumors in the head and neck region is controversial. Here we report the Southern California Kaiser Permanente experience with these patients. Methods and Materials From January 1969 through December 1994, 106 patients were eligible for this retrospective analysis. Distribution of nodal staging was as follows: 14 N1, 27 N2A, 39 N2B, 2 N2C, and 24 N3. Initial treatment included excisional biopsy alone in 12, radical neck dissection alone in 29, radiotherapy alone in 24, excisional biopsy followed by radiotherapy in 15, and radical neck dissection plus postoperative radiation in 26 patients. Results Except for two patients, all patients have had a minimum follow-up of 5 years. Overall, 57 patients (54%) have had recurrences. Only two patients (3%) who had received radiotherapy as part of their initial treatment had an appearance of a potential primary site inside the irradiated field vs 13 patients (32%) who had not received radiotherapy (p = .006). Combined modality therapy resulted in fewer neck relapses, particularly in patients with advanced neck disease. Including salvage, surgery alone as the initial treatment resulted in 81% ultimate tumor control above the clavicle for patients with N1 and N2a disease without extracapsular extension. The 5-year survival for the entire population was 53%. Radiotherapy alone resulted in poor survival in patients with advanced/unresectable neck disease. No significant difference in survival based on the initial treatment was found. The statistically significant adverse factors in determining survival included advanced nodal stage and the presence of extracapsular extension. Conclusions Radiotherapy is very effective in reducing the rate of appearance of a potential primary site. However, in the absence of advanced neck disease (N1 and N2A without extracapsular extension), radiotherapy can be reserved for salvage. Radiotherapy alone results in poor outcomes in patients with advanced/unresectable neck disease, and incorporation of concurrent chemotherapy and cytoprotective agents should be investigated. © 2002 Wiley Periodicals, Inc.

A Decision Tool for Predicting Sentinel Node Accuracy from Breast Tumor Size and Grade

THE BREAST JOURNAL, Issue 6 2007
FRCS (Gen. Surg.), Nathan Coombs BSc
Abstract:, The ability to predict axillary lymph node involvement in breast cancer patients in the preoperative setting is invaluable. This study provides a simple set of formulae to enable clinicians to make informed decisions in the management of screen-detected breast cancer. The tumor pathology reports were obtained of all 4,585 women identified between 1996 and 1999 in New South Wales (NSW) with T1 or T2 breast cancer by the statewide co-ordinated breast screening service (BreastScreen NSW). Equations predicting node positivity were calculated by linear regression analysis and, from published sentinel node false-negative rates, the probability of retrieval of a false-negative axillary lymph node by sentinel node biopsy was calculated for tumors of different size and grade. Node involvement was identified in 1,089 (23.8%) of women. A linear relationship for tumor size, grade, and nodal involvement was predicted by: frequency (%) = 1.5 × tumor size (mm) + 2 (or 6 or 10) for grade I (or II or III) tumors. Assuming a 7.5% false-negative rate, the probability of retrieving a false-negative sentinel node ranged from 0.8% for a patient with a 5 mm, grade I carcinoma to 6.0% for a 50 mm, grade III tumor. These simple formulae are easy to use in a clinical setting. The reference table enables breast surgeons to inform a patient about the absolute probability of false-negative sentinel biopsy rates for patients with screen-detected carcinomas when size can be estimated from preoperative imaging and when tumor grade is often available from preoperative core biopsy. Patients with large, T2 breast tumors may be best treated with axillary dissection rather than sentinel node biopsy alone due to the risk of under-staging the woman's disease and also the high probability of finding a positive sentinel node.

Background:, A retrospective cohort study was performed in 1063 women diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3) (previously termed carcinoma in situ, CIS) in the National Women's Hospital, Auckland, New Zealand. The study describes the clinical management and outcomes for women with CIN3 diagnosed in the decade of 1965,1974, when treatment with curative intent was withheld in an unethical clinical study of the natural history of CIS. A comparison is made with women who were diagnosed earlier (1955,1964) and later (1975,1976). Aims:, The aim of the study is to record the medical encounters, frequency and management of cytological abnormalities and the occurrence of invasive cancers. The medical records, cytology and histopathology were reviewed and data linked with cancer and death registers. Results:, Women diagnosed with CIN3 in 1965,1974 (n = 422), compared with those diagnosed earlier (n = 385) or later (n = 256): (i) were less likely to have initial treatment with curative intent (51% vs 95 and 85%, respectively); (ii) had more follow-up biopsies (P < 0.0005); (iii) were more likely to have positive cytology during follow-up (P < 0.005) and positive smears that were not followed within six months by a treatment with curative intent (P < 0.005); and (iv) experienced a higher risk of cancer of the cervix or vaginal vault (RR = 3.3 compared with the first period, 95% CI: 1.7,5.3). Among women diagnosed in 1965,1974, those initially managed by punch or wedge biopsy alone had a cancer risk ten times (95% CI: 3.9,25.7) higher than women initially treated with curative intent. Conclusions:, During the ,clinical study' (1965,1974), women underwent numerous interventions that were aimed to observe rather than treat their condition, and their risk of cancer was substantially increased.

Endophthalmitis in the western Sydney region: a case-control study

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 6 2001

ABSTRACT Background: A retrospective case-control study was conducted to investigate risk factors for endophthalmitis following routine intraocular surgery. Methods: A review was performed of consecutive cases of endophthalmitis from three teaching hospitals in the western Sydney region and matched controls from the same institutions between 1996 and 1998. Results: There were 31 cases and 66 controls. Eighty procedures were phacoemulsification, 15 conventional extracapsular cataract extraction, and two were penetrating keratoplasties. Of the 80 patients who had phacoemulsification surgery, 50 had a clear corneal incision, and 26 had a scleral incision (four were unknown). Logistic regression showed an increased risk of endophthalmitis with surgical complications (P = 0.002) and clear cornea temporal incisions (P = 0.007). Risk of endophthalmitis was reduced with use of subconjunctival injections (P = 0.008). The yield for the Gram stain was 47% and for culture was 67%. Anterior chamber tap in addition to vitreous biopsy alone did not increase the yield for microorganism (P = 0.78). Mean visual acuity on presentation was hand movement with 13 patients (50%) showing visual improvement following intravitreal injections of antibiotics (P = 0.003). Visual prognosis did not correlate with presenting visual acuity but appeared to be better in those who grew Staphylococcus epidermidis or were culture negative. Conclusions: Although this study is unable to draw definite conclusions regarding risk of endophthalmitis in clear corneal temporal cataract surgery, sufficient data suggest the importance of incision type and location. Surgical complication is an important risk factor for endophthalmitis. Use of subconjunctival antibiotic injections at the conclusion of the procedure is recommended. [source]


Ductal adenocarcinoma of the prostate diagnosed on transurethral biopsy or resection is not always indicative of aggressive disease: implications for clinical management

Study Type , Prognosis (case series) Level of Evidence 4 OBJECTIVE To report the clinicopathological characteristics of 23 cases of ductal adenocarcinoma of the prostate (DCP) and discuss the implications for clinical management, as DCP is considered an aggressive subtype of prostate adenocarcinoma (PA). PATIENTS AND METHODS The presence of DCP in transrectal ultrasonography-guided prostate biopsy (TRUSB) is associated with adverse pathological findings at radical prostatectomy (RP) and clinical outcomes, and the significance of detecting DCP initially in transurethral biopsy (UB) or transurethral resection (TURP) in the present era of screening with prostate-specific antigen (PSA) is unclear. The study included 23 cases of pure DCP without acinar PA diagnosed on UB or TURP. Demographic information, serum PSA level, follow-up surgical procedures (RP, TURP or TRUSB) and outcome data were collected. RESULTS The mean age of the men was 67.5 years and the mean PSA level before the procedure was 12.5 ng/mL; 14 cases were detected on UB and nine were diagnosed on TURP. The mean (range) follow-up was 4 (1,23) months after the initial procedure. In all, 21 (89%) patients had DCP or PA in follow-up procedures. Two (11%) patients had no residual cancer, one on RP and the other on two repeat TURPs. DCP or PA was found in 12 RP cases; four patients had Gleason score 7 PA, three of which were organ-confined, and eight had Gleason score ,8 PA. Extraprostatic extension, seminal vesicle invasion and regional lymph node metastasis were present in seven, six and two cases, respectively. CONCLUSIONS Most DCP diagnosed on UB or TURP in this contemporary series was associated with aggressive PA, but a subset presented as a small periurethral tumour with no concomitant acinar PA, and was eradicated by the initial biopsy/TURP alone. We recommend that patients with a diagnosis of DCP on UB or TURP undergo follow-up TURP and TRUSB before radical surgery is offered. [source]
