Breast-Conservation Treatment Outcomes: A Community Hospital's Experience

THE BREAST JOURNAL, Issue 1 2009
Barbara D. Florentine MD
Abstract:, In the United States, the majority of early breast cancer patients choose breast-conserving treatment in the community setting, yet there is a paucity of literature describing outcomes. In this paper, we describe our experience with breast-conserving treatment in a small community hospital. Our hospital tumor registry was used to identify breast cancer cases diagnosed at our hospital between 1997 and 2003. We limited our study to those women with initial attempts at breast-conserving surgery (BCS) who had follow-up oncology treatment at on-campus affiliated oncological services. We looked at factors that influence survival for early stage 0,II disease such as tumor and patient characteristics, completeness of local surgical tumor excision, and adjuvant treatment. We also evaluated the percentage of cases in which the initial BCS did not achieve adequate surgical oncological results and the number and type of subsequent surgeries that were required to achieve this goal. There were 185 cases with a median patient age of 55 and a median follow-up time of 53 months. Most tumors were stage 0,I (68%) or stage II (23%). A single surgery was deemed sufficient to achieve the desired oncological outcome in 54% of cases; the remaining cases (46%) required additional surgeries. A final margin of 5 mm or greater was successfully achieved in 81% of cases. Ninety-two percent of the patients underwent radiotherapy, 65% received hormonal therapy, and 49% underwent chemotherapy. One hundred and sixty one patients had successful breast-conserving surgeries (87%) and 24 patients (13%) ultimately required mastectomy. There were four loco-regional recurrences and 19 deaths during the study period. Our disease-free survival rate for early-stage cancer (stage 0,II) was 91% at 5 years. Our study shows that high-quality patient outcomes for breast-conserving treatment can be achieved in the community setting. [source]


Results of treatment when orthopaedic surgeons follow gait-analysis recommendations in children with CP

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 7 2008
Bjørn Lofterød MD
The aim of the present study was to assess the outcome of orthopaedic surgery in ambulant children with cerebral palsy, when the orthopaedic surgeons followed the recommendations from preoperative three-dimensional gait analysis. 55 children, mean age 10y 11mo, were clinically evaluated by orthopaedic surgeons who proposed a surgical treatment plan. After gait analysis and subsequent surgery, three groups were defined. In group A, there was agreement between clinical proposals, gait-analysis recommendations, and subsequent surgery in 128 specific surgical procedures. In group B, 54 procedures were performed based on gait analysis, although these procedures had not been proposed at the clinical examination. In group C, 55 surgical procedures that had been proposed after clinical evaluation were not performed because of the gait-analysis recommendations. The children underwent follow-up gait analysis 1 to 2 years after the initial analysis. The kinematic results were satisfactory, with improvement in most of the gait parameters in children who had undergone surgery and no significant deterioration in those who were not operated. In group A, there were significant improvements in maximum hip extension in stance, minimum knee flexion in stance, timing of maximum knee flexion in swing and knee range of motion, maximum ankle dorsiflexion in stance, and mean femur rotation in stance. In group B, there were significant improvements in maximum hip extension in stance, minimum knee flexion in stance, and knee range of motion. We conclude that gait analysis was useful in confirming clinical indications for surgery, in defining indications for surgery that had not been clinically proposed, and for excluding or delaying surgery that was clinically proposed.

Mortuary behaviour reconstruction through palaeoentomology: a case study from Chachapoya, Perú

INTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 3 2005
K. C. Nystrom
Abstract This paper explores the contribution that applied forensic entomology can make to our understanding of prehistoric mortuary behaviour. Samples of insect remains were recovered from a mummy bundle that has been attributed to the Chachapoya people who occupied the northern highlands of Perú from ca. AD 800 to ca. AD 1532. The insects were identified to the family level and used to create a hypothetical timeline of post-mortem interval before the construction of the mummy bundle. The individual in question suffered from a number of blunt force insults to the head, followed by two and possibly three trepanation events. We speculate the initial insect colonisation to have taken place almost immediately following injury and subsequent surgery, occurring before the individual's death. Insect succession patterns and timing estimates for the appearance of periosteal reactive bone suggest that the individual was wrapped shortly following death. The application of such modern forensic techniques holds vast promise for addressing issues concerning Chachapoya mortuary behaviour and, further, these results can expand our understanding of mummy studies in general.

Accuracy of MRI for predicting the circumferential resection margin, mesorectal fascia invasion, and tumor response to neoadjuvant chemoradiotherapy for locally advanced rectal cancer

JOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 5 2009
Seung Ho Kim MD
Abstract Purpose To evaluate the diagnostic accuracy of MRI for predicting the circumferential resection margin (CRM), mesorectal fascia (MRF) invasion, and the tumor response to neoadjuvant chemoradiotherapy (CRT) for locally advanced rectal cancer. Materials and Methods Sixty-five consecutive patients with locally advanced rectal cancer (,T3 or lymph node-positive) who underwent neoadjuvant CRT and subsequent surgery were enrolled in this retrospective study. Two blinded radiologists independently reviewed both the pre- and post-CRT rectal MR images and measured the post-CRT CRM; they recorded their confidence level with respect to the MRF invasion and tumor response using a 5-point scale. The diagnostic accuracy of each reviewer was calculated using receiver operating characteristic curve (ROC) analysis. Results The measured CRM was not significantly different from the reference standard (mean difference, ,1.4 mm; 95% limits of agreement, ,8.3,5.4 mm; interclass correlation coefficient, 0.82). The diagnostic accuracy (Az) for determining MRF invasion was 0.890 for reviewer 1 (95% confidence interval [CI], 0.788,0.954) and 0.829 for reviewer 2 (95% CI, 0.715,0.911). The Az for predicting complete or near-complete regression was 0.791 for reviewer 1 (95% CI, 0.672,0.882) and 0.735 for reviewer 2 (95% CI, 0.611,0.837). Conclusion MRI provides accurate information regarding the CRM of locally advanced rectal cancer after neoadjuvant CRT; it also shows relatively high accuracy for predicting MRF invasion and moderate accuracy for assessing tumor response.

Pancreatitis in adult orthotopic liver allograft recipients: Risk factors and outcome

LIVER TRANSPLANTATION, Issue 3 2000
Deborah J. Verran
Acute pancreatitis (AP) has been described after orthotopic liver transplantation but is uncommon in stable patients after the initial perioperative phase. The aim of this study is to review our experience with AP occurring more than 2 months after primary allografting and determine possible contributing factors plus patient outcome. A review of patient files and the unit database was performed. AP was diagnosed in 9 of 298 patients (3%) on 12 occasions. The incidence of AP was greater in men (8 of 163 men) than women (1 of 135 women; P< .04). Underlying factors to each episode of AP were biliary manipulation (4 of 12 episodes; 33%), history of recent alcohol ingestion (3 of 12 episodes; 25%), and malignancy in the region of the pancreas (2 of 12 episodes; 16%). AP was associated with a diagnosis of either hepatic artery thrombosis combined with biliary tract complications (P< .005) or malignancy (P< .004). In 7 of 12 episodes of AP (58%), conservative management alone was successful. In 3 of 9 patients (33%), subsequent surgery was required. One patient died of pancreatic malignancy. In conclusion, AP is uncommon in stable liver transplant recipients. Male sex, complications of hepatic artery thrombosis, and malignancy in the region of the pancreas are associated with AP in this study. [source]


(217) Selective Nerve Root Injections Can Accurately Predict Level of Nerve Impairment and Outcome for Surgical Decompression: A Retrospective Analysis

PAIN MEDICINE, Issue 3 2001
Kevin Macadaeg
There remains significant controversy regarding the use of a vertebral selective nerve root injection (SNI) as a diagnostic and therapeutic tool. In addition, the frequency of use of such procedures in patients with radiculopathy has increased dramatically in the last few years. Based on a Medline review there has been no studies combining cervical and lumbar SNI results and comparing preoperative diagnosis to surgical findings and outcome. The purpose of this paper is to retrospectively examine and compare the sensitivity, specificity and predictive value of a good surgical outcome in patients who had an SNI and subsequent surgical intervention. 101 patients from a 1996 thru 1999 database, who were referred to 10 spine surgeons (2 orthopedic and 8 neurosurgeon) for either cervical or lumbar radiculopathy, and had SNI and various imagery studies and subsequent surgery. Patients receive SNIs at our institution if there is a discrepancy between physical exam and radiologic imagery or to confirm a putative pain generator in multilevel pathology. These patients were then retrospectively analyzed with regard to correlation to surgical level and surgical outcome. SNIs were performed by one of three pain specialists in our clinic. Approximation of the appropriate nerve root sleeve was performed using fluoroscopic imagery, a nerve stimulator and contrast. After nerve root stimulation and neurography, 0.5,0.75 cc of lidocaine 2% was injected. Pre- and post-procedural visual analog scale (VAS) pain scores were obtained from the non-sedated patient. A SNI was considered positive or negative if the patient had immediate appendicular pain relief of greater or less then ninety percent respectively. The study was designed to include only those patients that had a SNI, regardless of result, and subsequently had surgical decompression in an attempt to treat the pain that initially prompted the SNI. A statistical analysis was then performed comparing preoperative data to surgical findings and outcome. Overall, 101 patients had SNIs who subsequently underwent surgical decompression. Average duration of symptoms prior to SNI was 1.5,12 months (4 months mean). Fifteen patients presented with cervical and 86 with lumbar radiculopathy. There were a total of 110 procedures performed on these patients. VAS scores of <2 and overall pain reduction openface> 90% with respect to their pre-procedural appendicular were used to determine if a SNI was positive, negative or indeterminate. All of these patients had an MRI or CT with or without a myelogram and all went to surgery. The results yield that SNIs are able to predict surgical findings with 94% and 90% sensitivity and specificity, respectively. A good surgical outcome was determined if the patient would do the surgery again, if they were satisfied or very satisfied and had a VAS of <3 at 6- and 12-month intervals. Our data revealed that a positive SNI was able to predict a good 6-month outcome with 95% and 64% sensitivity and specificity, respectively. At 12-months, similar results were obtained of 95% and 56%. Preoperative MRI results were also evaluated and revealed a 92% sensitivity in predicting surgical findings. We had 24 false positive MRI results and 0 true negatives. Interestingly we had 8 diabetic (IDDM or NIDDM) patients or nearly 8% of our total. The odds ratio of a diabetic having a bad outcome at 12 months was 5.4 to 1. Diabetics had a 50% likelihood of having a bad 12-month outcome versus 16% for non-diabetics with a p value of 0.066. We also looked at gender, smoking history and presence of cardiovascular disease and found no significant relationship with outcomes. Our data indicate that SNIs, when performed under rigorous method, is a highly valuable tool that can accurately determine level of nerve root impairment and outcome in patients being considered for surgical decompression. With a sensitivity of 94% and a specificity of 90%, SNIs offer a major advantage over other diagnostic modalities in patients with difficult-to-diagnose radiculopathies. [source]


Evolution in the Assessment and Management of Trigeminal Schwannoma

THE LARYNGOSCOPE, Issue 2 2008
Bharat Guthikonda MD
Abstract Educational Objective: At the conclusion of this presentation, the participants should be able to understand the contemporary assessment and management algorithm used in the evaluation and care of patients with trigeminal schwannomas. Objectives: 1) Describe the contemporary neuroradiographic studies for the assessment of trigeminal schwannoma; 2) review the complex skull base osteology involved with these lesions; and 3) describe a contemporary management algorithm. Study Design: Retrospective review of 23 cases. Methods: Chart review. Results: From 1984 to 2006, of 23 patients with trigeminal schwannoma (10 males and 13 females, ages 14,77 years), 15 patients underwent combined transpetrosal extirpation, 5 patients underwent stereotactic radiation, and 3 were followed without intervention. Of the 15 who underwent surgery, total tumor removal was achieved in 9 patients. Cytoreductive surgery was performed in six patients; of these, four received postoperative radiation. One patient who underwent primary radiation therapy required subsequent surgery. There were no deaths in this series. Cranial neuropathies were present in 14 patients pretreatment and observed in 17 patients posttreatment. Major complications included meningitis (1), cerebrospinal fluid leakage (2), major venous occlusion (1), and temporal lobe infarction (1). Conclusions: Trigeminal schwannomas are uncommon lesions of the skull base that may occur in the middle fossa, posterior fossa, or both. Moreover, caudal extension results in their presentation in the infratemporal fossa. Contemporary diagnostic imaging, coupled with selective use of both surgery and radiation will limit mor-bidity and allow for the safe and prudent management of this uncommon lesion. [source]


Combined antegrade and retrograde endoscopic retroperitoneal bypass of ureteric strictures: a modification of the ,rendezvous' procedure

BJU INTERNATIONAL, Issue 7 2010
David R. Yates
Study Type , Therapy (case series) Level of Evidence 4 OBJECTIVE To evaluate our experience of treating complicated iatrogenic ureteric strictures with a combined antegrade and retrograde endoscopic retroperitoneal bypass technique, a modification of the so-called ,rendezvous' procedure. PATIENTS AND METHODS Seven patients presented to our institution between 2004 and 2008 after developing a complicated iatrogenic ureteric stricture, impassable with solitary antegrade or retrograde stenting techniques. In most cases there was a significant loss of ureteric continuity, with some strictures of up to 10,12 cm. After initial temporizing management with a percutaneous nephrostomy, each patient had a radiological ,rendezvous' procedure to insert a JJ stent and restore ureteric continuity. After 6 months, the JJ stents were removed and the patients evaluated by symptom assessment, serial measurements of serum creatinine and diuretic renography (F-15 mercaptoacetyl triglycine). RESULTS All seven ,rendezvous' procedures were successful and a ureteric stent was inserted across or around the stricture in all cases. Five of seven patients whose follow-up was >6 months had their stent removed successfully. At a median follow-up of 21 months, all patients are alive and none has required subsequent surgery. Six of the seven patients presented with significant symptoms and they are all currently symptom-free, which we consider to be a successful clinical outcome. No patient has developed significant renal impairment (estimated glomerular filtration rate (<30 mL/min) but we could only confirm successful unequivocal renographic drainage in one patient. CONCLUSION Combining antegrade radiological and retrograde endourological techniques, it is possible to restore ureteric continuity with a JJ stent, even in situations with extensive loss of the ureteric lumen. This reduces the need for morbid open surgical repair and offers a long-term solution to patients who might otherwise be consigned to less favourable conservative measures. [source]


What steps should be considered in the patient who has had a negative cervical exploration for primary hyperparathyroidism?

CLINICAL ENDOCRINOLOGY, Issue 5 2009
Barney Harrison
Summary The key to cure of the patient with persistent primary hyperparathyroidism is a clear understanding of the investigations, operative procedure and pathology related to the initial procedure. Reinvestigation and subsequent surgery should be performed in a specialist unit. A logical pathway of increasingly sophisticated localization studies (MIBI, ultrasound, CT/MRI, selective venous catheterization for PTH) will usually guide the surgeon to the missing parathyroid gland/s. Improved preoperative localization can facilitate the use of a minimally invasive small incision approach. The surgeon must have a detailed knowledge of the nuances of parathyroid embryology and a meticulous surgical technique, not only to identify and safely remove the retained gland/s but also do so without causing unnecessary morbidity. Results of re-operation (84,98% cure) from centres of excellence are highly commendable, yet the use of ,new' technology (that includes intra-operative PTH) has not translated into improved outcomes in all cases. Some parathyroid glands are extremely difficult to find! Re-operative parathyroid surgery is a challenge, sometimes easy, and on other occasions extremely difficult. [source]
