RESUMEN

Familial aggregation of nasopharyngeal carcinoma (NPC) has been widely reported. The excess risk is about 4-8-fold among first-degree relatives of NPC patients compared with those without a family history of the disease. We used nasopharyngoscopy and a narrow-band image system (NBI) to screen NPC high-risk patients and identify a good tool for the early detection of NPC in these high-risk groups. We recruited all available, affected blood relations of the patients. When NPC patients were more distant relatives, such as cousins, we recruited their shared second-degree relatives, such as unaffected aunts and uncles, to genetically connect the NPC cases. We performed transnasal endoscopy, first in white-light mode, then under the NBI system. There were two NBI patterns in NPC: microvascular proliferation and engorged blood vessels. The NBI pattern in normal nasopharyngeal mucosa was a regular cobblestone pattern. A prospective study included 211 asymptomatic members from 154 NPC families. We found four cases of NPC, all with a tumor stage of T1. In one patient (1/4), MRI revealed a 2-cm-diameter neck lymphadenopathy (N1). The correlation between conventional nasopharyngoscopy and NBI was very high (κ = 0.798, P = 0.000). In conclusions, NBI is not superior to conventional nasopharyngoscopy for the early detection of NPC in unaffected members of families with NPC history. The long-term follow-up is necessary in high-risk NPC patients. Further studies will be needed to determine which screening tool-conventional nasopharyngoscopy, NBI, or EB virus titer-is most effective.

RESUMEN

BACKGROUND: Cranial nerve involvement at disease presentation of nasopharyngeal carcinoma was not uncommon. We investigated the prognosis of patients with T4-locally advanced NPC, with or without cranial nerve involvement, and compared the outcome of patients treated using different radiotherapy techniques. METHODS: In this retrospective study, 83 T4-locally advanced NPC patients were diagnosed according to the seventh edition of the American Joint Committee on Cancer staging system. All patients were treated using three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiation therapy (IMRT). The survival rate was analyzed using the Kaplan-Meier method. RESULTS: The 5-year overall, locoregional-free, and disease-free survival rates of patients treated using IMRT were 88.9%, 75.2%, and 69.2%, respectively. The outcome in these patients was significantly better than that in patients treated using 3D-CRT, with survival rates of 58.2%, 54.4%, and 47.2%, respectively. There was no significant difference in the 5-year overall, locoregional-free, and disease-free survival rates of the patients with (64.2%, 60.5%, and 53.5%, resp.) and without (76.9%, 63.6%, and 57.6%, resp.) cranial nerve involvement. CONCLUSION: Locally advanced NPC patients treated using IMRT had significantly better outcomes than patients treated using 3D-CRT. Our results showed that the outcome of T4 NPC patients with or without cranial nerve involvement was not different.

RESUMEN

Pleomorphic adenomas, or benign mixed tumors, make up 65% of all salivary gland tumors. They also can be found as solid tumors in other parts of the head and neck region, such as the auditory canal, the eyelids, and the orbital area. In this study, we investigated extra-major salivary gland pleomorphic adenomas of the head and neck region retrospectively at a tertiary care center. Between March 1998 and June 2009, 37 patients underwent primary surgery for extra-major salivary gland pleomorphic adenoma of the head and neck. The duration of symptoms, radiographic findings, operative procedures, and pathologic findings were documented. Of the 37 patients enrolled, 22 were male and 15 were female, with a median age of 57 years. Tumors were found in the soft palate, hard palate, nasopharynx, orbital area, trachea, buccal mucosa, cheek, nasal septum, upper lip, lower eyelid, and external auditory canal. Cellular variant of the pleomorphic adenoma was found in four patients, while the remaining patients presented with the classic variant. No myxoid subgroup was noted in our study. Carcinoma ex pleomorphic adenoma was observed only in one patient for whom radical surgery was performed. Twenty-eight patients (76%) had long-term follow-ups, with the average follow-up period being 4.5 years. Local recurrence was observed in three patients, and they underwent revision surgery during the follow-up period. Our results indicate that extra-major salivary gland pleomorphic adenomas are most commonly found in the soft palate. Wide excision was the treatment of choice, although its efficacy might be compromised with cosmetics and functional structures of the head and neck. Therefore, long-term follow-up of patients is necessary.

RESUMEN

BACKGROUND: We attempted to determine whether use of a topical intranasal corticosteroid (INCS) preoperatively had an effect on bacterial culture and antibiotic sensitivity in chronic rhinosinusitis with nasal polyposis. METHODS: In a prospective study, patients that were diagnosed with rhinosinusitis with nasal polyposis received INCS for one month before functional endoscopic sinus surgery. Bacterial culture testing, obtained under telescope from a source near the middle meatus, was performed before and after INCS. Antibiotic sensitivity was also performed. RESULTS: One hundred fifty-six patients were enrolled in the prospective study, and 115 patients completed the procedures. The male-to-female ratio was 83:32 and the age range was 14 approximately 76 years (46.7 +/- 2.1). The positive culture rates were 80.9% and 79.1% pre-INCS treatment and post-INCS treatment, respectively. There was no significant difference between pretreatment and posttreatment samples in bacterial culture rate. The single bacterial culture rates were 66.7% and 65.9% pre-INCS treatment and post-INCS treatment, respectively. The drug sensitivities to oxacillin and cephaxolin showed no significant difference in coagulase negative Staphylococcus and Staphylococcus aureus. CONCLUSION: INCS did not influence the rate of bacterial culture or antibiotic sensitivity in patients with chronic rhinosinusitis with nasal polyps.
