Long-term outcomes after endoscopic endonasal surgery for nonfunctioning pituitary macroadenomas

OBJECTIVENonfunctioning pituitary adenomas are benign, slow-growing tumors. After gross-total resection (GTR) or subtotal resection (STR), tumors can recur or progress and may ultimately require additional intervention. A greater understanding of long-term recurrence and progression rates following complete or partial resection and the need for further intervention will help clinicians provide meaningful counsel for their patients and assist data-driven decision-making.METHODSThe authors retrospectively analyzed their institutional database for patients undergoing endoscopic endonasal surgery (EES) for nonfunctioning pituitary macroadenomas (2003–2014). Only patients with follow-up of at least 5 years after surgery were included. Tumor volumes were measured on pre- and postoperative MRI. Tumor recurrence was defined as the presence of a 0.1-cm3 tumor volume after GTR, and tumor progression was defined as a 25.0% increase in residual tumor after STR.RESULTSA total of 190 patients were included, with a mean age of 63.8 ± 13.2 years; 79 (41.6%) were female. The mean follow-up was 75.0 ± 18.0 months. GTR was achieved in 127 (66.8%) patients. In multivariate analysis, age (p = 0.04), preoperative tumor volume (p = 0.03), Knosp score (p < 0.001), and Ki-67 (p = 0.03) were significant predictors of STR. In patients with GTR, the probability of recurrence at 5 and 10 years was 3.9% and 4.7%, and the probability of requiring treatment for recurrence was 0.79% and 1.6%, respectively. In 63 patients who underwent STR, 6 (9.5%) received early postoperative radiation and did not experience progression, while the remaining 57 (90.5%) were observed. Of these, the probability of disease progression at 5 and 10 years was 21% and 24.5%, respectively, and the probability of requiring additional treatment for progression was 17.5% and 21%. Predictors of recurrence or progression in the entire group were Knosp score (p < 0.001) and elevated Ki-67 (p = 0.03). Significant predictors of progression after STR in those who did not receive early radiotherapy were cavernous sinus location (p < 0.05) and tumor size > 1.0 cm3 (p = 0.005).CONCLUSIONSFollowing GTR for nonfunctioning pituitary adenomas, the 10-year chance of recurrence is low and the need for treatment even lower. After STR, although upfront radiation therapy may prevent progression, even without radiotherapy, the need for intervention at 10 years is only approximately 20% and a period of observation may be warranted to prevent unnecessary prophylactic radiation therapy. Tumor volume > 1 cm3, Knosp score ≥ 3, and Ki-67 ≥ 3% may be useful metrics to prompt closer follow-up or justify early prophylactic radiation therapy.

The Mean

Object The use of endoscopic endonasal surgery (EES) for skull base pathologies in the pediatric population presents unique challenges and has not been well described. The authors reviewed their experience with endoscopic endonasal approaches in pediatric skull base surgery to assess surgical outcomes and complications in the context of presenting patient demographics and pathologies. Methods A retrospective review of 133 pediatric patients who underwent EES at our institution from July 1999 to May 2011 was performed. Results A total of 171 EESs were performed for skull base tumors in 112 patients and bony lesions in 21. Eighty-five patients (63.9%) were male, and the mean age at the time of surgery was 12.7 years (range 2.3–18.0 years). Skull base tumors included angiofibromas (n = 24), craniopharyngiomas (n = 16), Rathke cleft cysts (n = 12), pituitary adenomas (n = 11), chordomas/chondrosarcomas (n = 10), dermoid/epidermoid tumors (n = 9), and 30 other pathologies. In total, 19 tumors were malignant (17.0%). Among patients with follow-up data, gross-total resection was achieved in 16 cases of angiofibromas (76.2%), 9 of craniopharyngiomas (56.2%), 8 of Rathke cleft cysts (72.7%), 7 of pituitary adenomas (70%), 5 of chordomas/chondrosarcomas (50%), 6 of dermoid/epidermoid tumors (85.7%), and 9 cases of other pathologies (31%). Fourteen patients received adjuvant radiotherapy, and 5 received chemotherapy. Sixteen patients (15.4%) showed tumor recurrence and underwent reoperation. Bony abnormalities included skull base defects (n = 12), basilar invagination (n = 4), optic nerve compression (n = 3) and trauma (n = 2); preexisting neurological dysfunction resolved in 12 patients (57.1%), improved in 7 (33.3%), and remained unchanged in 2 (9.5%). Overall, complications included CSF leak in 14 cases (10.5%), meningitis in 5 (3.8%), transient diabetes insipidus in 8 patients (6.0%), and permanent diabetes insipidus in 12 (9.0%). Five patients (3.8%) had transient and 3 (2.3%) had permanent cranial nerve palsies. The mean follow-up time was 22.7 months (range 1–122 months); 5 patients were lost to follow-up. Conclusions Endoscopic endonasal surgery has proved to be a safe and feasible approach for the management of a variety of pediatric skull base pathologies. When appropriately indicated, EES may achieve optimal outcomes in the pediatric population.

Giant Pituitary Adenomas

Object Giant pituitary adenomas (> 4 cm in maximum diameter) represent a significant surgical challenge. Endoscopic endonasal surgery (EES) has recently been introduced as a treatment option for these tumors. The authors present the results of EES for giant adenomas and analyze the advantages and limitations of this technique. Methods The authors retrospectively reviewed the medical files and imaging studies of 54 patients with giant pituitary adenomas who underwent EES and studied the factors affecting surgical outcome. Results Preoperative visual impairment was present in 45 patients (83%) and partial or complete pituitary deficiency in 28 cases (52%), and 7 patients (13%) presented with apoplexy. Near-total resection (> 90%) was achieved in 36 patients (66.7%). Vision was improved or normalized in 36 cases (80%) and worsened in 2 cases due to apoplexy of residual tumor. Significant factors that limited the degree of resection were a multilobular configuration of the adenoma (p = 0.002) and extension to the middle fossa (p = 0.045). Cavernous sinus invasion, tumor size, and intraventricular or posterior fossa extension did not influence the surgical outcome. Complications included apoplexy of residual adenoma (3.7%), permanent diabetes insipidus (9.6%), new pituitary insufficiency (16.7%), and CSF leak (16.7%, which was reduced to 7.4% in recent years). Fourteen patients underwent radiation therapy after EES for residual mass or, in a later stage, for recurrence, and 10 with functional pituitary adenomas received medical treatment. During a mean follow-up of 37.9 months (range 1–114 months), 7 patients were reoperated on for tumor recurrence. Three patients were lost to follow-up. Conclusions Endoscopic endonasal surgery provides effective initial management of giant pituitary adenomas with favorable results compared with traditional microscopic transsphenoidal and transcranial approaches.

OBJECTIVE When comparing endoscopic endonasal surgery (EES) and transcranial microsurgery (TCM) for adult and mixed-age population craniopharyngiomas, EES has become an alternative to TCM. To date, studies comparing EES and TCM for pediatric craniopharyngiomas are sparse. In this study, the authors aimed to compare postoperative complications and surgical outcomes between EES and TCM for pediatric craniopharyngiomas. METHODS The data of pediatric patients with craniopharyngiomas who underwent surgery between February 2009 and June 2021 at a single center were retrospectively reviewed. All included cases were divided into EES and TCM groups according to the treatment modality received. The baseline characteristics of patients were compared between the groups, as well as surgical results, perioperative complications, and long-term outcomes. To control for confounding factors, propensity-adjusted analysis was performed. RESULTS Overall, 51 pediatric craniopharyngioma surgeries were identified in 49 patients, among which 35 were treated with EES and 16 were treated with TCM. The proportion of gross-total resection (GTR) was similar between the groups (94.3% for EES vs 75% for TCM, p = 0.130). TCM was associated with a lower rate of hypogonadism (33.3% vs 64.7%, p = 0.042) and a higher rate of growth hormone deficiency (73.3% vs 26.5%, p = 0.002), permanent diabetes insipidus (DI) (60.0% vs 29.4%, p = 0.043), and panhypopituitarism (80.0% vs 47.1%, p = 0.032) at the last follow-up. CSF leakage only occurred in the EES group, with no significant difference observed between the groups (p > 0.99). TCM significantly increased the risk of worsened visual outcomes (25.0% vs 0.0%, p = 0.012). However, TCM was associated with a significantly longer median duration of follow-up (66.0 vs 40.5 months, p = 0.007) and a significantly lower rate of preoperative hypogonadism (18.8% vs 60.0%, p = 0.006). The propensity-adjusted analysis revealed no difference in the rate of recurrence, hypogonadism, or permanent DI. Additionally, EES was associated with a lower median gain in BMI (1.5 kg/m2 vs 7.5 kg/m2, p = 0.046) and better hypothalamic function (58.3% vs 8.3%, p = 0.027) at the last follow-up. CONCLUSIONS Compared with TCM, EES was associated with a superior visual outcome, better endocrinological and hypothalamic function, and less BMI gain, but comparable rates of GTR, recurrence, and perioperative complications. These findings have indicated that EES is a safe and effective surgical modality and can be a viable alternative to TCM for pediatric midline craniopharyngiomas.

Abstract Background Recently the endoscopic endonasal surgery (EES) has been introduced as a modality for the treatment of patients with craniopharyngiomas. In this study, we describe our initial experience in treatment of 29 patients with craniopharyngiomas using this approach. Methods Twenty-nine consecutive patients with craniopharyngiomas who had undergone EES in a 5-year period were studied retrospectively. Patients underwent preoperative and postoperative endocrinologic and ophthalmologic evaluations. Radiologic characteristics of tumors and extent of resection were determined. The recurrence and complications were evaluated. Results Pituitary and visual dysfunction were observed preoperatively in 89.7 and 86% of patients, respectively. After EES, visual outcome either showed an improvement or else remained unchanged in 92.3% of the cases; however, pituitary function remained unchanged and even got worsened in 34.6% of the cases. Prevalence of diabetes insipidus before and after surgery was 58.6 and 69.2%. The rate of gross total resection was 62%. Moreover, 86.2% of the tumors were almost totally resected (more than 95% of the tumor size resected). After surgery, cerebrospinal fluid (CSF) leak and meningitis occurred in four (13.8%) and two (6.9%) patients, respectively. Perioperative mortality was seen in two of the cases (6.9%). The mean follow-up was 25 months and tumor recurrence was discovered in four patients (15.3%). Conclusion The EES with the goal of maximal and safe tumor resection could be used for the treatment of most craniopharyngiomas. Although the rates of visual improvement and gross tumor resection are high, CSF leak, pituitary dysfunction, and meningitis are serious concerns.
