Cancer-associated facial pain can be caused by a variety of pathologic conditions. Here the authors describe the symptoms and incidence of facial pain secondary to three separate anatomic ...subcategories of cancer. The authors subsequently discuss the effectiveness and drawbacks of the most common methods of treatment.
To review our experience with multidisciplinary surgical management of locally advanced adenoid cystic carcinoma of the lacrimal gland.
We present a case series of 7 patients with lacrimal gland ...adenoid cystic carcinoma treated at our institution between June 2001 and October 2003. Clinical records, histologic sections, and radiographic images were reviewed.
The study included 3 men and 4 women (mean age at diagnosis, 44 years). All 7 patients underwent an orbital exenteration with bone removal. Five patients had an orbitectomy through a craniotomy approach and 2 patients had an exenteration through a fronto-orbito-zygomatic approach, all with removal of the bone of the superior and lateral wall. Six patients underwent reconstruction of the socket through the use of a vascularized flap. The surgical approach involved a neurosurgeon, an oculoplastic or head and neck surgeon, and a plastic surgeon. Six patients received postoperative radiation therapy. One patient with a recurrent tumor had already received radiation therapy, which precluded additional radiation therapy after surgical resection. The radiation field included the orbit and the skull base because all patients had evidence of perineural invasion. As of this writing, there have been no local recurrences. Five patients had development of distant metastases and died of disease, at follow-up times from 12 to 32 months after surgery. Two patients are alive without evidence of disease, both at 24 months' follow-up.
Orbitectomy with bone removal may be indicated for achieving local and regional control in advanced cases of adenoid cystic carcinoma of the lacrimal gland. This surgery does not decrease the risk of distant metastasis. The cases in our series highlight the locally invasive and metastatic behavior of this cancer.
Abstract Background Intraventricular meningiomas account for 0.5–3% of all intracranial meningiomas. The majority occur in the atrium of the lateral ventricle. Surgical experience with ...intraventricular meningiomas is rare in the literature, and several surgical approaches exist. Methods Between 1987 and 2007, 13 patients underwent resection of intraventricular meningiomas. All patients had tumors of the lateral ventricles. These patients were retrospectively identified and their records reviewed. Results Eleven tumors were found in the atrium, one in the frontal horn, and one in the body of the lateral ventricle. In 9 of 13 cases, the tumor occurred in the left lateral ventricle. Patients commonly presented with headache and cognitive difficulties. A visual field deficit was noted preoperatively in one patient. Four patients underwent preoperative angiography, but no patients underwent embolization. Gross total resection was achieved in all cases: 6 via a middle temporal gyrus approach, 5 via a superior parietal lobule approach, and 2 via a transcallosal approach. Image-guided stereotaxis was used in 6 cases. Pathology was benign in 12 of 13 cases; atypical features were identified in one case. There was no operative mortality, and no patients showed evidence of recurrence. Postoperatively, 3 patients developed new cognitive-linguistic deficits that subsequently resolved. One of these patients developed a new visual field deficit after surgery. Conclusions Several approaches are available for the surgical treatment of intraventricular meningiomas. Tumor location, extension, and laterality drive the selection algorithm for these approaches. Preoperative angiography is rarely useful, and surgical cure is the rule.
Skull base metastases (SBM) are rare among all tumors affecting the base of the skull. Because of their rarity, they have received limited attention in the published medical literature. Several ...clinical syndromes associated with SBM have been described. Knowledge of these syndromes and maintenance of a high index of suspicion are important for an early diagnosis. The majority of patients are best managed by radiotherapy. Other therapeutic options include stereotactic radiosurgery, chemotherapy, and surgery. Surgical resection is reserved for a minority of well-selected patients. The decision to intervene surgically is based on patients' clinical status, the degree of control of systemic disease, the accessibility of the lesion, and the potential morbidity of the procedure. Well-designed trials and evidence-based practice guidelines are not available. The management of these patients largely depends of the experience of the treating medical team.
To compare the outcome from adjuvant and delayed radiotherapy (RT) after surgery in patients with benign cerebral meningioma.
Between March 1953 and January 2001, 92 patients with benign cerebral ...meningioma (WHO grade I) were treated with surgery. Forty-eight patients underwent gross total resection (GTR), and 44 patients underwent subtotal resection (STR). Treatments were classified as GTR (
n=48), STR+adjuvant RT (
n=12), STR alone (
n=32). The prognostic factors were assessed as, gender, the Karnofsky performance score (KPS) (≥90 vs. <90), the extent of surgery, and adjuvant or delayed RT. The endpoints analyzed were progression-free survival (PFS) and overall survival (OS). Overall survival curve of the study population is compared with the age-adjusted expected survival curve for the US population born in 1970.
The median follow-up was 7.7 years. The 5-year PFS and OS rates for all patients were 65 and 93%, respectively. The 5-year PFS rates in patients treated with GTR and STR were 77 and 52%, respectively (
P=0.02). Patients treated with STR+adjuvant RT had significantly better PFS (91%) at 5 years than with STR alone (38%) (
P=0.0005). Gender showed no statistically significant impact on either PFS or OS (
P>0.05). However, multivariate analysis showed the KPS to have a statistically significant effect on OS (
P=0.02). The OS rate was the same across all three treatment groups. The age-adjusted expected survival curve for the US population born in 1970 lay within the confidence intervals for the overall survival curve of the study population.
Although OS was not affected, adjuvant RT appeared to significantly reduce tumor progression. However, only a prospective randomized trial can adequately determine whether adjuvant or delayed radiotherapy is the better approach in patients with subtotally resected benign meningioma.
To identify the incidence of radiologically and histologically documented bony invasion of the lacrimal gland fossa by adenoid cystic carcinoma.
The authors reviewed the records of all 18 patients ...with lacrimal gland adenoid cystic carcinoma surgically treated at their institution from 1997 to 2009 for imaging findings (blinded review) and histologic findings on evaluation of the lacrimal gland fossa. Preoperative CT and/or MRI findings were available for 17 patients.
The 8 men and 10 women ranged in age from 9 to 69 years. American Joint Committee on Cancer tumor stages after preoperative imaging were as follows: T1N0M0, 2 patients; T2N0M0, 5 patients; T3aN0M0, 2 patients; T3bN0M0, 5 patients; T3bN0M1, 2 patients; T4bN0M0, one patient; and TxN0M0, one patient. Preoperative imaging suggested bony involvement of the lacrimal gland fossa in 13 patients (76.5%); this was histologically confirmed in 11 of the 13. Preoperative imaging suggested no bone involvement in 4 patients, 3 of whom had bone involvement by histology. Overall, 14 of 17 histologically evaluable cases (82.3%) had invasion of the lacrimal gland fossa. Histologic findings of bone/periosteal involvement led to upstaging of 3 tumors. Metastases developed in 8 of 18 patients and trended with basaloid histology (p = 0.066).
Adenoid cystic carcinoma of the lacrimal gland is associated with bone invasion in essentially all but the smallest of tumors (T1). This high rate of bone involvement may warrant addressing the bony walls during surgery for adenoid cystic carcinoma of the lacrimal gland.
Abstract
Optic nerve sheath meningiomas (ONSMs) account for less than 2% of meningiomas and 1.7% of orbital tumors. Although rare, the management of these tumors is important as unilateral blindness ...often results in untreated cases. Radiotherapy has emerged as the preferred treatment. However, therapies for ONSMs are controversial due to the variable natural history of the disease and limitations of surgical and radiotherapy options. A 60-year-old woman presented with monocular left diminished color perception and blurred vision. Magnetic resonance imaging demonstrated a homogenously enhancing 5-mm left optic nerve mass with evidence of nerve compression. Conservative management was advised. However, 1 month after diagnosis her visual acuity deteriorated further. Because of the small focal location of the tumor within the optic canal, surgery was considered. Given the tumor's location inferomedial to the optic nerve, an endoscopic endonasal approach to the optic canal was performed. This patient recovered fully with resolution of visual symptoms immediately following surgery. Postoperative imaging 24 hours after surgery demonstrated gross total resection of the tumor; 1 year postoperatively the patient has a normal ophthalmologic examination. This report highlights the value of endoscopic endonasal approaches in the management of select optic canal pathology, otherwise inaccessible via transcranial approaches.
Despite recent advances in surgery of the cavernous sinus, meningiomas in that area offer a formidable challenge. The rationale for aggressive surgical removal of cavernous sinus meningiomas is based ...on the presumption that the extent of removal is inversely related to the rate of recurrence. Over the past 10 years, 41 patients with histologically benign meningiomas involving the cavernous sinus underwent aggressive surgery. Total removal, as confirmed by intraoperative inspection and postoperative radiological studies, was achieved in 31 patients (76%). Twelve patients have been followed for more than 5 years; 10 underwent total tumor removal and only one of these experienced recurrence (5 years after surgery). The other two patients underwent subtotal removal and had symptomatic and radiological evidence of regrowth 3 and 4 years after surgery. Pre-existing cranial nerve deficits improved in only 14% of the patients, remained unchanged in 80%, and worsened permanently in 6%. Seven patients experienced a total of 10 new cranial nerve deficits, four of which involved the nerves subserving ocular motor function. Extraocular muscle function did not worsen in the 25 patients with a seeing eye ipsilateral to the tumor, and no instance of visual worsening occurred. Two patients died 4 months after surgery, one from severe delayed vasospasm and hypothalamic infarction and the other because of a myocardial infarction. Another patient died from a pulmonary embolus on the 9th postoperative day. There were three instances of cerebral ischemia; one was transient, lasting less than 24 hours, while two were related to injury of the middle cerebral artery and resulted in residual hemiplegia. Other complications included three cases of nonfatal pulmonary emboli, two cerebrospinal fluid leaks, and one instance each of exposure keratitis, acute hypothyroidism, and cerebral edema.
After brain metastasis resection, whole brain radiotherapy decreases local recurrence, but might cause cognitive decline. We did this study to determine if stereotactic radiosurgery (SRS) to the ...surgical cavity improved time to local recurrence compared with that for surgical resection alone.
In this randomised, controlled, phase 3 trial, we recruited patients at a single tertiary cancer centre in the USA. Eligible patients were older than 3 years, had a Karnofsky Performance Score of 70 or higher, were able to have an MRI scan, and had a complete resection of one to three brain metastases (with a maximum diameter of the resection cavity ≤4 cm). Patients were randomly assigned (1:1) with a block size of four to either SRS of the resection cavity (within 30 days of surgery) or observation. Patients were stratified by histology of the primary tumour, metastatic tumour size, and number of metastases. The primary endpoint was time to local recurrence in the resection cavity, assessed by blinded central review of brain MRI scans by the study neuroradiologist in the modified intention-to-treat population that analysed patients by randomised allocation but excluded patients found ineligible after randomisation. Participants and other members of the treatment team (excluding the neuroradiologist) were not masked to treatment allocation. The trial is registered with ClinicalTrials.gov, number NCT00950001, and is closed to new participants.
Between Aug 13, 2009, and Feb 16, 2016, 132 patients were randomly assigned to the observation group (n=68) or SRS group (n=64), with 128 patients available for analysis; four patients were ineligible (three from the SRS group and one from the observation group). Median follow-up was 11·1 months (IQR 4·8–20·4). 12-month freedom from local recurrence was 43% (95% CI 31–59) in the observation group and 72% (60–87) in the SRS group (hazard ratio 0·46 95% CI 0·24–0·88; p=0·015). There were no adverse events or treatment-related deaths in either group.
SRS of the surgical cavity in patients who have had complete resection of one, two, or three brain metastases significantly lowers local recurrence compared with that noted for observation alone. Thus, the use of SRS after brain metastasis resection could be an alternative to whole-brain radiotherapy.

Objectives/Hypothesis
Olfactory neuroblastoma (ONB) is a rare sinonasal malignant neoplasm that is known to develop late recurrence. The aim of this study is to evaluate the long‐term outcomes of ...patients with ONB and to determine the factors associated with prognosis.
Study Design
Retrospective study.
Methods
A retrospective review of the medical records of 139 patients diagnosed with ONB at MD Anderson Cancer Center was performed between 1991 and 2016. Descriptive statistics were calculated, and Kaplan–Meier curves were utilized to assess survival.
Results
Median follow‐up time was 75 months. Overall, 129 patients (92.8%) had surgery as part of their treatment and 82 (58.9%) patients received postoperative radiation therapy (PORT) or concurrent chemoradiotherapy. Endoscopic approaches were utilized for 72 patients, 69.4% of whom had pure endoscopic endonasal approaches. Five‐year overall survival and disease‐specific survival were 85.6% and 93.4%, respectively. Recurrence rate was 39.6% with a median time to recurrence of 42 months. Among the 31 patients who received elective nodal irradiation (ENI), two patients developed neck recurrence (6.4%) compared with 20 who developed neck recurrence when ENI was omitted (34.4%) (P = .003). Advanced Kadish stage, orbital invasion, intracranial invasion, and presence of cervical lymphadenopathy at the time of presentation were significantly associated with poor survival.
Conclusion
ONB has an excellent survival. Surgical resection with PORT when indicated is the mainstay of treatment. Endoscopic approaches can be used as a good tool. Elective neck irradiation reduces the risk of nodal recurrence among patients with clinically N0 neck. Despite the excellent survival, recurrence rate remains high and delayed, highlighting the need for long‐term surveillance.
