Object Subnormal postoperative serum cortisol levels indicate successful surgery and predict long-term remission of Cushing disease. Given the short serum half-lives of adrenocorticotropic hormone (ACTH) and cortisol, it is unclear why the decline in cortisol postoperatively is delayed for 18–36 hours. Furthermore, the relevance of the rate of cortisol drop immediately after surgery has not been investigated. Methods Patient data were analyzed from a prospectively accrued database. After surgery, cortisol replacement was withheld and serum cortisol measurements were obtained every 6 hours until values of 1.0–2.0 μg/dl or less were reached. The authors selected patients in whom serum cortisol dropped to 2 μg/dl or less after surgery (101 patients). Tumor resection was categorized as follows: 1) complete resection using the histological pseudocapsule as a surgical capsule, 2) complete piecemeal resection), 3) known incomplete resection, and 4) total hypophysectomy. Results The median time to reach a cortisol level of less than or equal to 2.0 μg/dl was 9.9, 19.4, 25.3, and 29.5 hours with hypophysectomy, pseudocapsule, incomplete resection, and piecemeal techniques, respectively. Pseudocapsule resection produced a faster decline in cortisol than piecemeal techniques (p = 0.0001), but not as rapid a decline as hypophysectomy (p = 0.033). Conclusions Complete resection by other techniques is associated with delayed cortisol decline compared with pseudocapsule surgery, which may represent the product of residual tumor cells and therefore may explain the higher rate of recurrent disease associated with piecemeal techniques. The prompt drop in cortisol after hypophysectomy compared with patients with pseudocapsule surgery suggests that the corticotrophs of the normal gland can secrete ACTH for 10–36 hours after surgery despite prolonged and severe hypercortisolism.

Background: Post-operative delayed hormone dysfunction (DHD) in patients with nonfunctioning pituitary adenomas (NFPA) is highly variable and is predicted based on limited evidence. This study was undertaken to assess the likelihood of developing new DHD and its relation to the extent of tumor resection and recurrence. Methods: Four hundred fifty-five prospectively collected patient files were reviewed from our Program’s database. Inclusion criteria: NFPA; underwent surgery; and minimum follow-up of two years. Tumor recurrence was correlated with DHD (starting one year post-operatively) based on standardized annual imaging and hormone testing. Results: Eighty-nine patients met our inclusion criteria: 39 males and 50 females; mean follow-up was 4.3yrs (ranging from 2 to 11yrs). With no post-op residual tumor, the probability of developing DHD was only 7% by six years; no patient in this group developed DHD after three years of follow-up. In contrast, by six years, the probability of DHD was 33% in patients with residual stable tumor, and 54% in those with tumor recurrence/growth. Conclusions: By six years, approximately one third of patients with incomplete resection, and over half with tumor regrowth, will likely develop DHD. In contrast, the risk of DHD with complete tumor resection is <10% and, when seen, occurs within three years of surgery.

OBJECT Cerebral gangliogliomas (GGs) are highly associated with intractable epilepsy. Incomplete resection due to proximity to eloquent brain regions or misinterpretation of the resection amount is a strong negative predictor for local tumor recurrence and persisting seizures. A potential method for dealing with this obstacle could be the application of intraoperative high-field MRI (iopMRI) combined with neuronavigation. METHODS Sixty-nine patients (31 female, 38 male; median age 28.5 ± 15.4 years) suffering from cerebral GGs were included in this retrospective study. Five patients received surgery twice in the observation period. In 48 of the 69 patients, 1.5-T iopMRI combined with neuronavigational guidance was used. Lesions close to eloquent brain areas were resected with the implementation of preoperative diffusion tensor imaging tractography and blood oxygenation level–dependent functional MRI (15 patients). RESULTS Overall, complete resection was accomplished in 60 of 69 surgical procedures (87%). Two patients underwent biopsy only, and in 7 patients, subtotal resection was accomplished because of proximity to critical brain areas. Excluding the 2 biopsies, complete resection using neuronavigation/iopMRI was documented in 33 of 46 cases (72%) by intraoperative imaging. Remnant tumor mass was identified intraoperatively in 13 of 46 patients (28%). After intraoperative second-look surgery, the authors improved the total resection rate by 9 patients (up to 91% [42 of 46]). Of 21 patients undergoing conventional surgery, 14 (67%) had complete resection without the use of iopMRI. Regarding epilepsy outcome, 42 of 60 patients with seizures (70%) became completely seizure free (Engel Class IA) after a median follow-up time of 55.5 ± 36.2 months. Neurological deficits were found temporarily in 1 (1.4%) patient and permanently in 4 (5.8%) patients. CONCLUSIONS Using iopMRI combined with neuronavigation in cerebral GG surgery, the authors raised the rate of complete resection in this series by 19%. Given the fact that total resection is a strong predictor of long-term seizure control, this technique may contribute to improved seizure outcome and reduced neurological morbidity.

Purpose To assess the role of residual tumor resection performed after high-dose chemotherapy (HDCT) in patients with relapsed or refractory germ cell tumors (GCT). Patients and Methods Between July 1987 and October 1999, postchemotherapy resections of residual tumors were performed in 57 patients who had been treated with HDCT for relapsed or refractory GCT and who had achieved a partial remission to this treatment. Results Complete resections of residual masses were achieved in 52 (91%) of 57 patients who were rendered disease free; in five (9%) of 57 patients, the resections were incomplete. Resection of a single site was performed in 39 (68%) of 57 patients, and the remaining 18 (32%) of 57 patients required interventions at two or more residual tumor sites. Necrosis was found in 22 (38%) of 57 patients, mature teratoma with or without necrosis was found in nine (16%) of 57 patients, and viable cancer with or without additional necrosis or mature teratoma was found in 26 (46%) of 57 patients. Viable cancer consisted either of residual germ cell or undifferentiated cancer in 22 (85%) of 26 patients, with additional non-GCT histologies in the remaining four patients. Patients with viable cancer had a significantly inferior outcome after surgery compared with patients with necrosis and/or mature teratoma even if all cancer was completely resected. Pulmonary lesions with a diameter of more than 2 cm were the only predictive variable for viable cancer in univariate analysis. Conclusion Resections of all residual tumors should be attempted in patients with relapsed or refractory GCT and partial remissions after HDCT.

Abstract Context Recurrence of Cushing disease (CD) can occur even decades after surgery. Biomarkers to predict recurrence of CD after surgery have been studied but are inconclusive. Objective The aim of our study was to identify specific biomarkers that can predict long-term remission after neurosurgery. Design Identification of specific biomarkers to predict long-term remission of CD was performed by logistic regression analysis followed by Kaplan–Meier survival analysis, using recurrence as the dependent variable. Setting A total of 260 patients with CD identified from our institutional research patient data registry search tool and from patients who presented to our longitudinal multidisciplinary clinic between May 2008 and May 2018 underwent statistical analysis. Interventions Data on clinical features, neuro-imaging study, pathology, biochemistry, and treatments were collected by reviewing digital chart records. Main Outcome Measure Postoperative cortisol as a biomarker to predict long-term remission after surgical treatment for CD. Results By logistic regression analysis, postoperative day 1 (POD1) morning (5-10 am) serum cortisol, female sex, and proliferative index had significant association with CD recurrence (odds ratio [OR] = 1.025, 95% CI: 1.002-1.048, P = .032). In contrast, the postoperative nadir cortisol (OR = 1.081, 95% CI: 0.989-1.181, P = .086), urinary free cortisol (OR = 1.032, 95% CI: 0.994-1.07, P = .098), and late night salivary cortisol (OR = 1.383, 95% CI: 0.841-2.274, P = .201) had no significant correlation with recurrence. A significant association between POD1 morning serum cortisol and long-term CD remission was verified by Kaplan–Meier analysis when using POD1 morning serum cortisol &lt;5 μg/dL as the cut-off. Conclusions The POD1 morning serum cortisol level has a significant association with CD recurrence.

The Impact

Purpose Although intensive multimodal treatment has improved the prognosis of patients with metastatic neuroblastoma, the impact of primary tumor resection on outcome is a matter of medical debate. Patients and Methods Patients from the German prospective clinical trial NB97 with stage 4 neuroblastoma and age 18 months or older at diagnosis were included. Operation notes and imaging reports were reviewed by two independent experienced physicians. Finally, the extent of tumor resections was correlated with local control rate and outcome. Results A total of 278 patients were included in this study. Image-defined risk factors present at diagnosis were found to be predictive for the extent of tumor resection at first (P < .001) and best (P < .001) operation. No patient died from surgery. Before chemotherapy, complete resection, incomplete resection, and biopsy or no surgery were performed in 6.1%, 5.0%, and 88.5% of patients, respectively. The extent of first operation had no impact on event-free survival (EFS; P = .207), local progression–free survival (LPFS; P = .195), and overall survival (OS; P = .351). After induction chemotherapy, 54.7% of patients underwent complete resection of the primary tumor, 30.6% underwent incomplete resection, and 13.3% had only biopsy or no surgery of the primary tumor. The extent of best operation also had no impact on EFS (P = .877), LPFS (P = .299), and OS (P = .778). Moreover, multivariate analyses showed that surgery did not affect EFS, LPFS, and OS. Conclusion In intensively treated patients with stage 4 neuroblastoma age 18 months or older at diagnosis, surgery of the primary tumor site has no impact on local control rate and outcome.

✓ Meningeal melanocytomas are uncommon lesions. They are generally considered to be benign tumors that derive from leptomeningeal melanocytes. A rare case of a metastatic spinal meningeal melanocytoma is presented. All relevant cases reported in literature since 1972, when the term “meningeal melanocytoma” was first used, were reviewed. Rates of tumor recurrence from 1 to 5 years were calculated for this rare lesion, based on published data and on additional information obtained from personal contact with most of the authors. Recurrency rates of 47 patients suitable for evaluation were correlated with the different therapeutic approaches. Complete tumor resection alone and incomplete resection alone followed by irradiation appeared to be superior to incomplete resection alone in terms of disease-free survival. Statistical significance was achieved for complete tumor resection at follow up between 1 and 4 years (range p = 0.010–0.050) and for incomplete resection combined with radiotherapy after 2 years (p = 0.034). Complete tumor resection should be considered the best therapeutic option, followed by incomplete resection combined with postoperative radiotherapy.

Background:Cushing disease (CD) constitutes a challenging condition for the pituitary surgeon. Given the variety of factors affecting outcomes in CD, it is uncertain whether the newer endoscopic technique improves the results of surgery.Methods:A review was conducted of CD cases at our institution between 2000 and 2010. Analysis was done to: determine if surgical technique had an effect on outcome, identify the predictors of outcome and provide details of failed cases. Remission was defined as normal postoperative 24-hour urinary free cortisol (24-h UFC), suppression of morning serum cortisol to <50 nmol/L after 1mg of dexamethasone or being dependent on steroid replacement.Results:Forty-two patients met our inclusion criteria. Average follow-up period was 33 months. There were 15 macroadenomas and 27 microadenomas. Seventeen patients had an endoscopic transsphenoidal surgery and twenty-five patients had a microscopic transsphenoidal procedure. Long-term overall remission was achieved in 26 (62%) patients. There was no significant difference in remission rates between the two techniques (p value 0.757). Patient's subjective symptomatic improvement and drop of morning serum cortisol in the postoperative period to less than 100 nmol/L correlated with long-term remission (p value 0.0031and 0.0101, respectively) while repeat surgery was the only predictor of the lack of postoperative remission (p value 0.0008).Conclusions:Revision surgery predicted poor remission rate for CD. Within the power of our study size, there was no difference in outcome between the endoscopic and microscopic approaches. Surgical outcomes should be reviewed in association with remission criteria used in a study.

Object. Non—small cell lung carcinomas with spinal and brachial plexus involvement have traditionally been considered to be Stage IIIb lesions and therefore unresectable. Advances in spinal surgery, the application of magnetic resonance (MR) imaging, and improvements in neoadjuvant therapy require a reassessment of the potential for complete resection. Methods. The authors conducted a retrospective review of all procedures involving the resection of superior sulcus tumors with spinal or brachial plexus involvement performed between 1985 and 1999. Assessment or resectability and operative planning were based on an MR imaging classification scheme in which the extent of spinal involvement was considered. Class A tumors involved the periosteum of the vertebral body (VB) (16 patients); Class B, distal neural foramen without epidural compression (eight patients); Class C, proximal neural foramen with epidural compression (four patients); and Class D, bone involvement (VB or posterior elements) with or without epidural involvement (14 patients). Brachial plexus involvement was present in 21 patients, including 17 with T-1 nerve root only and four with C-8 or lower-trunk infiltration. Complete tumor resection was achieved in 27 patients and incomplete resection in 15. Complications occurred in 14 patients, two of which were related to instrumentation failures. The overall median survival was 1.44 years. The median survival for the complete and incomplete resection groups were 2.84 and 0.79 years, respectively (p = 0.0001). There was no statistical difference in survival among classification groups. Conclusions. Complete tumor resection of superior sulcus tumors is possible in selected patients in whom involvement of the spinal column and/or brachial plexus is present. Preoperative MR imaging is essential for evaluation of the spine and surgical planning. Survival and cure are dependent on complete resection, regardless of the extent of spinal involvement.

AbstractCalcifying fibrous tumor (CFT) is a benign tumor entity which can present in a variety of different sites. Till date, eight cases with a mediastinal manifestation have been published in literature. Surgical removal is the treatment of choice for this often incidentally detected tumor. Surgery of thoracic CFT may be challenging due to its localization within the mediastinum. A 10-year old boy with a right-sided thoracic pectus carinatum-like deformity was referred for further evaluation, incidentally, revealing a mediastinal mass in computed tomography (CT). Laboratory results were all within normal range. Magnetic resonance imaging (MRI) showed a large tumor in the upper anterior mediastinum suggesting expansive but not infiltrative character. The tumor was displacing surrounding structures like the heart and the diaphragm. Lower venous stasis with dilation of the inferior cava vein could be demonstrated. The tumor was considered to be of benign dignity and surgical removal was indicated. Complete tumor resection could be achieved through a sternotomy approach, along with thymectomy. A partial resection of both the pericardium and diaphragm was required due to adhesion with soft tissue at those sites. The specimen's size was 320 mm × 145 mm × 100 mm, histologically confirmed as CFT. The patient showed no residual tumor at 3- and 9-month follow-up. This case is a report on a large mediastinal CFT which underwent successful complete surgical removal. Following tumor resection, prognosis is considered to be good; however, key issue is complete resection to avoid local tumor recurrence.
