Objective  To assess the feasibility of treating patients with high-risk stage III and IV squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx with perioperative adenovirus-p53 (INGN 201) gene therapy along with surgery and chemoradiotherapy.

Design and Setting  A phase 2 study in a multi-institutional setting within the Southwest Oncology Group.

Patients  Thirteen individuals who met the following entry criteria: newly diagnosed, previously untreated squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx; selected stage III or IV disease without distant metastases; and surgically resectable disease.

Interventions  Surgery, perioperative INGN 201 gene therapy, and postoperative chemoradiotherapy.

Main Outcome Measures  Overall patient status, tumor status, adverse effects, accrual rate, and percentage of patients successfully receiving the required doses of INGN 201.

Results  All 13 patients received surgery and perioperative INGN 201 injections in the primary tumor bed and the ipsilateral neck. In addition, 3 patients received injections in the contralateral neck. Three patients did not receive chemoradiotherapy. One patient had a grade 2 fistula of the oral cavity. Of the 10 patients with evaluable data, 2 experienced grade 4 adverse events, 1 owing to hypokalemia, hyponatremia, vomiting, leukopenia, and neutropenia and 1 owing to increased aspartate aminotransferase and alanine aminotransferase levels. Seven other patients experienced grade 3 adverse events. The estimate of 1-year progression-free survival is 92%.

Conclusions  This trial demonstrated the feasibility of handling and delivering a very complex gene vector safely in multiple cooperative group institutions without significant incident. Intraoperative INGN 201 gene therapy is technically feasible, but it has many logistical problems when performed in a multi-institutional setting. Regulatory requirements might have hindered accrual in this multi-institutional setting. Disease control seems to be promising; however, no definitive conclusion can be made with this small sample size.

Objective  To evaluate the oncologic outcomes of patients with sinonasal cancer treated with endoscopic resection.

Design  Retrospective review.

Setting  Tertiary care academic cancer center.

Patients  All patients with biopsy-proved malignant neoplasm of the sinonasal region who were treated with endoscopic resection between 1992 and 2007 were included in the study, and their charts were reviewed for demographics, histopathologic findings, treatment details, and outcome.

Main Outcome Measures  Oncologic outcomes, including disease recurrence and survival.

Results  Of a total of 120 patients, 93 (77.5%) underwent an exclusively endoscopic approach (EEA) and 27 (22.5%) underwent a cranioendoscopic approach (CEA) in which the surgical resection involved the addition of a frontal or subfrontal craniotomy to the transnasal endoscopic approach. Of the 120 patients, 41% presented with previously untreated disease, 46% presented with persistent disease that had been partially resected, and 13% presented with recurrent disease after prior treatment. The most common site of tumor origin was the nasal cavity (52%), followed by the ethmoid sinuses (28%). Approximately 10% of the tumors had an intracranial epicenter, most commonly around the olfactory groove. Tumors extended to or invaded the skull base in 20% and 11% of the patients, respectively. An intracranial epicenter (P < .001) and extension to (P = .001) or invasion of (P < .001) the skull base were significantly more common in patients treated with CEA than in those treated with EEA. The primary T stage was evenly distributed across all patients as follows: T1, 25%; T2, 25%; T3, 22%; and T4, 28%. However, the T-stage distribution was significantly different between the EEA group and the CEA group. Approximately two-thirds (63%) of the patients treated with EEA had a lower (T1-2) disease stage, while 95% of patients treated with CEA had a higher (T3-4) disease stage (P < .001). The most common tumor types were esthesioneuroblastoma (17%), sarcoma (15%), adenocarcinoma (14%), melanoma (14%), and squamous cell carcinoma (13%). Other, less common tumors included adenoid cystic carcinoma (7%), neuroendocrine carcinoma (4%), and sinonasal undifferentiated carcinoma (2%). Microscopically positive margins were reported in 15% of patients. Of the 120 patients, 50% were treated with surgery alone, 37% received postoperative radiation therapy, and 13% were treated with surgery, radiation therapy, and chemotherapy. The overall surgical complication rate was 11% for the whole group. Postoperative cerebrospinal fluid leakage occurred in 4 of 120 patients (3%) and was not significantly different between the CEA group (1 of 27 patients) and the EEA group (3 of 93 patients) (P > .99). The cerebrospinal fluid leak resolved spontaneously in 3 patients, and the fourth patient underwent successful endoscopic repair. With a mean follow-up of 37 months, 18 patients (15%) experienced local recurrence, with a local disease control of 85%. Regional and distant failure occurred as the first sign of disease recurrence in 6% and 5% of patients, respectively. The 5- and 10-year disease-specific survival rates were 87% and 80%, respectively. Disease recurrence and survival did not differ significantly between the EEA group and the CEA group.

Conclusions  To the best of our knowledge, this is the largest US series to date of patients with malignant tumors of the sinonasal tract treated with endoscopic resection. Our results suggest that, in well-selected patients and with appropriate use of adjuvant therapy, endoscopic resection of sinonasal cancer results in acceptable oncologic outcomes.
