The purpose of this study was to determine the overexpression of both epidermal growth factor receptor (EGFR) and transforming growth factor-alpha (TGF-alpha) (a ligand of EGFR) in early laryngeal squamous cell carcinoma. In addition, we attempted to evaluate the prognostic values of our findings. Expression of EGFR and TGF-alpha in tumor tissue was examined immunohistochemically in 68 patients who had been treated with radiotherapy for early laryngeal cancer. Overexpression of the two factors was noted in 42.6% and 55.9%, respectively. No significant differences due to age, tumor size, and location or grade of cancer tissues were seen. Higher survival rates, found in patients with EGFR (-) and TGF-alpha (-) tumors as compared with those with EGFR (+) and TGF-alpha (+) (97.4%, 100% and 86.2%, 86.8%, respectively), were not statistically significant. The recurrence rates were similar between EGFR (+) and EGFR (-) (37.9% and 35.9%, respectively). However, the recurrence rate in patients with TGF-alpha (+) was significantly higher (57.9%) than in those with TGF-alpha (-) (10%; P<.01). Therefore overexpression of TGF-alpha may be an important indicator for recurrence in patients with early laryngeal squamous cell carcinoma treated by irradiation.

An evaluation of the psychological and cosmetic morbidity of 31 patients who had undergone breast conserving treatment (BCT group) and 71 patients who had undergone radical mastectomy (RM group) revealed that 85% and 73%, respectively, were satisfied with their operative results. BCT appeared superior to RM in relation to body image, with 93% of the BCT group indicating BCT as a future choice of treatment, whereas only 35% of the RM group indicated RM as a future choice of treatment. For 59% of the BCT patients, the results were considered excellent or good by a physician, but fear of recurrence was frequently expressed by both groups even though an early stage of breast cancer had been significantly more common in the BCT group than the RM group. Sexual adjustment was the same in both groups. Body image was thus concluded to have been improved by BCT rather than RM, but psychological morbidity was essentially the same in both groups.
