Renal clear cell carcinoma with thyroid and parotid metastases: A case report.

The present study reports a rare case of a renal clear cell carcinoma with thyroid and parotid metastases. A 56-year-old female, with a painless, right preauricular mass present for 6 months was referred to Renji Hospital (Shanghai, China). Physical examination revealed a mass of 3×3 cm, which was smooth, firm, immobile and non-tender.

67-kDa laminin receptor in human laryngeal squamous cell carcinoma.

Objectives/hypothesis: Abnormal interaction of epithelial cells with laminin component of basement membrane may account for altered biological behavior of cells, influencing proliferation, adhesion, and motility. In the current study, we investigated the role of 67-kDa laminin receptor (67LR), a high affinity receptor for laminin, in aggressiveness of laryngeal squamous cell carcinoma.

Methods: Thirty paraffin-embedded specimens and 20 fresh tissues of patients with laryngeal squamous cell carcinoma were analyzed using immunohistologic and reverse-transcriptase polymerase chain reaction techniques, respectively.

[Clinical research on 2228 cases of thyroid gland tumors].

Objective: To discuss outcome of thyroid tumor patients treated with surgery.

Methods: Total number of patients was 2228. These patients of thyroid tumors from 1992-2004 (2072 cases of benign thyroid diseases and 156 cases of thyroid carcinoma) were recruited.

[Expression and function of laminin receptor in laryngeal squamous cell carcinoma].

Objective: To investigate the role of 67 000 laminin receptor (LN-R) in the processes of invasion and metastasis of laryngeal squamous cell carcinoma.

Methods: Expression of 67 000 LN-R mRNA in 20 cases with laryngeal squamous cell carcinomas and corresponding normal tissues was determined by RT-PCR, and the relationship between its expression level and patients' clinicopathological features was analyzed. Expression of 67 000 LN-R on the surface of AMC-HN-8 laryngeal carcinoma cells was examined by flow cytometry.
