Primary thyroid lymphomas (PTLs) are closely correlated with the autoimmune reaction of thyroid. However, the molecular mechanisms of PTLs are still unclear. It is really necessary to improve the ability to differentiate between benign and malignant PTLs along with the introduction of some new molecular biology methods. The diagnosis and prognosis of PTLs depend on their histological features, pathological classification, and clinical stages. Customized therapy of PTLs becomes possible with the further advances in lymphoma's pathological classification, clinical stages, and international prognosis index standard.

Here, we present the case of a patient with bilateral choroidal metastases with extraocular extension in one eye. Metastasis of papillary thyroid carcinoma to the uvea is extremely rare, with only 6 patients reported in the literature. A 62-year-old man with a prior history of papillary thyroid carcinoma suffered the rapid loss of vision in his right eye. He had neovascular glaucoma, total retinal detachment, and a solitary choroidal mass. A month later, his left visual acuity also decreased because of a small macular choroidal mass. The right eye was enucleated and a nodular lesion over the sclera representing extraocular extension was observed. This tumor and the intraocular lesion were composed of papillary excrescences and cystic spaces and stained positively for thyroid transcription factor 1 and thyroglobulin, all confirming the diagnosis of metastatic papillary thyroid carcinoma. The tumor in the left eye was successfully treated with diode laser transpupillary thermotherapy. The patient expired within a month as a result of widespread pulmonary metastases. Papillary thyroid carcinoma may metastasize to the uvea bilaterally, cause rapid visual function loss, erode the sclera, and may extend outside the globe similar to choroidal melanoma. This aggressive ocular involvement was associated with a dismal prognosis in our patient.

Oncologists and scientists in the field of head and neck cancer exchanged their research findings and clinical experiences in the Sino-USA Symposium on Head and Neck Cancer, which was held January 6-7, 2012 in Guangzhou, China. The symposium was jointly organized by Sun Yat-sen University Cancer Center (SYSUCC) and the University of Texas MD Anderson Cancer Center (MDACC). The Guangdong Provincial Anti-Cancer Association and the Chinese Journal of Cancer also helped in organizing the conference. Speakers were from China (SYSUCC, the Chinese University of Hong Kong, Tianjin Medical University Cancer Institute and Hospital, and Fudan University Shanghai Cancer Center) and the United States (MDACC). The presentations covered most kinds of head and neck cancers and included both basic and clinical research progress. In particular, NPC was discussed in depth. The symposium explored the reality that cancer is complex and numerous questions remain to be answered, even though there has already been an enormous effort into research. International exchanges of experience and in-depth cooperation are definitely needed to improve our capability of caring for cancer patients. In this article, we provide highlights of the presentations.

OBJECTIVETo explore the clinicopathologic characteristics, treatment and prognosis of differentiated thyroid carcinoma (DTC) in adolescents.

METHODSThe data of 46 patients with DTC under the age of 18 years were retrospectively reviewed.

RESULTSTwenty patients were misdiagnosed in this group (43.5%). All patients received operation, including 39 unilateral neck dissection and 6 bilateral neck dissection, followed by postoperative thyrotropin suppressive therapy. There were 42 cases of papillary carcinoma (91.3%) and 4 cases of follicular carcinoma (8.7%). Cervical lymph node metastasis was found in 39 cases (84.8%). In the follow-up period of 1 to 25 years (mean 10 years), no death of thyroid carcinoma occurred.

CONCLUSIONSThe most common DTC in adolescents is papillary carcinoma with better prognosis regardless of the higher incidence of cervical lymph node metastasis. The optimal extent of primary thyroidectomy and neck dissection followed by postoperative thyrotropin suppressive therapy in adolescents with DTC may improve the quality of life and decrease the incidence of complications.

OBJECTIVETo investigate the management and prognosis of thyroid well-differentiated carcinoma invading the upper aerodigestive tract.

METHODSA retrospective analysis of the management was performed done 62 patients with thyroid well-differentiated carcinoma invading the upper aerodigestive tract. The main method of surgery was shaving excision, and the other means including partial thyrochondrectomy, total laryngectomy, sleeve tracheal resection, sternocleidomastoid myoperiosteal flap and myodermal flap reconstruction, or simply palliative excision. Some patients received postoperative radioactive isotope therapy and radiotherapy. All patients were followed-up for 2 to 15 years with an average of 6.5 years.

RESULTSThe best curative effect was proved in the patients with local invasion, with the lumen uninvolved and their locoregional control rate was 100.0% (17/17). And the second choice was in patients with more extensive involvement of the upper aerodigestive tract structures. For them, extensive surgical management was done attempting to remove all gross disease followed by reconstruction, their locoregional control rate was 87.5% (7/8). And the third place was designated to patients with local invasion for which shaving excision was performed even though minor residual disease was left, their locoregional control rate was 55.6% (5/9). The poorest result went to simple palliative excision. For 17 patients with minor residual tumor, the locoregional control rate of those who were given postoperative radioactive isotope therapy was significantly higher than those without.

CONCLUSIONAccording to the limits and degree of invasion in the upper aerodigestive tract by thyroid well-differentiated carcinoma, different ways of surgery is indicated. For patients with residual disease, radioactive isotope therapy should be used to improve the result and life quality. Advanced lesions should be given postoperative radio therapy.
