Phase I/II trial of outpatient docetaxel, cisplatin, 5-fluorouracil, leucovorin (opTPFL) as induction for squamous cell carcinoma of the head and neck (SCCHN).

The purpose of this study was to establish the maximum tolerated dose (MTD) of docetaxel in an outpatient docetaxel (T), cisplatin (P), 5-fluorouracil (5-FU) (F), and leucovorin (L) (opTPFL) regimen and to obtain preliminary assessment of opTPFL efficacy. Thirty-four patients with stage III or IV squamous cell carcinoma of the head and neck were treated with opTPFL. Docetaxel was escalated from 60 to 95 mg/m(2) in combination with 100 mg/m(2) cisplatin intravenous bolus, and 2,800 mg/m(2) 5-FU continuous infusion and 2,000 mg/m(2) leucovorin continuous infusion with prophylactic growth factors and antibiotics. Patients who achieved a complete (CR) or partial (PR) response to three cycles received definitive twice-daily radiation therapy. A total of 97 cycles were administered to 34 patients. The major acute toxicities were neutropenia and mucositis. The MTD of docetaxel was 90 mg/m(2) . Seventy-seven of 97 cycles of were administered on an outpatient basis. The overall clinical response rate to opTPFL was 94%, with 44% CRs and 50% PRs. The MTD of opTPFL is 90 mg/m(2) docetaxel. Outpatient administration of opTPFL is tolerable, feasible, and does not alter the ability to administer definitive radiation therapy on schedule.

Examining the safety of nasogastric tube placement after endoscopic sinus surgery.

Several cases of intracranial injury during the placement of nasogastric tubes have been reported, usually in the setting of anterior skull base fractures. The fovea ethmoidalis and sphenoid sinus are often exposed after endoscopic sinus surgery, so that these structures are potentially placed in the line of contact during nasogastric tube placement. In order to evaluate the ability of the fovea ethmoidalis and roof of the sphenoid sinus to withstand penetration from possible contact during nasogastric tube placement, 12 fresh cadaver heads were studied. After complete endoscopic ethmoidectomy and wide sphenoidotomy, standard 18F and 16F nasogastric tubes were inserted to produce deliberate direct contact with both the fovea ethmoidalis and the sphenoid sinus roof. No penetrations of the fovea occurred in 20 specimen sides with the 18F tube; penetration did occur with the 16F tube in 1 of 13 sides (7.7%). With respect to the sphenoid sinus, no intracranial penetrations occurred in 16 and 11 sides for the 18F and 16F tubes, respectively. The sphenoid sinus was easily entered even in the presence of an intact middle turbinate. These data suggest that although intracranial penetration during nasogastric intubation after endoscopic sinus surgery is an unlikely event, there is a non-negligible risk of such injury. Nasogastric intubation should be performed with caution in patients with a history of sinus surgery.

Kikuchi-Fujimoto disease of the neck. Update.

Kikuchi-Fujimoto disease (KFD) is a rare entity of uncertain cause that commonly presents with persistently enlarged cervical lymph nodes unresponsive to antibiotic therapy. Although it usually follows a benign course, KFD has been repeatedly misdiagnosed as malignant lymphoma; hence, clinicians and pathologists alike need to be aware of this disease entity. The newest developments regarding the etiology and course of KFD are presented through a review of the literature and a recent illustrative case.
