The limitation so direct or indirect laryngoscopy and laryngogram in detemining the exact site and anatomiclocation of laryngeal carcinoma were well documented by many authors. As compared with laryngoscopy and laryngogram, CT study for laryngeal cancer is more exact and accurate method demonstrating anatomic sites of involvement, invasion into deep soft tissue spaces of endolarynx, destruction of laryngeal cartilages and cervical metastasis. Fourteen laryngeal cancer patients proven by laryngoscopic biopsy were further examined by computed tomography for staging. The authors compared laryngoscopic findings with those of computed tomography, and their clinical, surgical and computed tomographic findings were analysed. The results were as follows; 1. All patients were proved as squamous cell carcinoma. They were 12 males and 2 females aged over 50 yrs. 2. Common clinical symptoms were hoarseness, dysphagia and swallowing difficulty. The pirmary anatomic sites determined by CT were 8 transglottic, 2 glottic, 2 supraglottic and 1 pyriform sinus respectively. They were 2 T1. 7 T2, 1 T3, 3 T4 by TNM systems, respectivly. (One case was difficult to evaluate exactly). 3. Invasion into deep soft tissue spaces of endolarynx, cartilage destruction, and neck metastasis were relatively predominant in transglottic caracinomas. 4.CT was superior in evaluating tumor invasion, especially into deep soft tissue spaces of endolarynx, laryngeal cartilages and metastasis ot soft tissue and lymph nodes of neck. However CT had some limitation in determining primary site of laryngeal cancer.

Thoracoscopic esophagectomy can be performed in esophageal diseases to reduce the postoperative complications. Recently, We encountered a case of esophageal cancer and successfully treated it by thoracoscopic esophagectomy with gastric pull-up. A 59-year-old male was presented with swallowing difficulty and an esophagogram, esophagoscopy, and chest CT showed an ulcerating tumor on the lower esophagus. The operation was performed in three stages: mobilization of the esophagus by thoracoscopic surgery, construction of a gastric tube through a laparotomy, and cervical anastomosis between the esophagus and the gastric pull-through. Hoarseness developed postoperatively, and the postoperative esophagogram showed leakage at the esophagogastric anastomotic site. The anastomotic leakage was healed following surgical drainage and the patient was discharged in good health. Hoarseness subsided spontaneously two months after surgery.

PURPOSE: We investigated prostate size and its correlation with final pathologic outcomes and prognosis. MATERIALS AND METHODS: From 1993 to 2009, 830 consecutive patients who underwent radical prostatectomy with follow-up duration of 12 months or more were included in this study. Patients were categorized according to prostate size as follows: group 1, prostate size < or =40 g (n=458), and group 2, prostate size >40 g (n=472). Preoperative parameters and postoperative pathologic outcomes were compared between groups. Multivariate analysis with Cox proportional hazards regression model was used to identify the pathologic and clinical factors affecting biochemical recurrence. RESULTS: Patients in group 1 had higher pathologic T stage (pT2a=17.7% vs. 23.9%, pT2b=1.1% vs. 0%, pT2c=40.4% vs. 39.8%, pT3a=29.5% vs. 21.0%, pT3b=10.7% vs. 13.2%, p=0.003) and higher positive surgical margin (40.3% vs. 33.1%, p=0.033) than did patients in group 2. Pathologic Gleason score was not significantly different between the two groups. The 5-year biochemical-recurrence-free survival was 62.3% for patients in group 1 and 73.2% for patients in group 2 (p=0.005). Multivariate Cox regression analysis showed that prostate size of 40 g or less (hazard ratio [HR], 1.378; 95% confidence interval [CI], 1.027 to 1.848; p=0.032), extracapsular extension (HR, 1.592; 95% CI, 1.147 to 2.209; p=0.005), positive surgical margin (HR, 2.348; 95% CI, 1.701 to 3.242; p<0.001), and pathologic Gleason sum (HR, 1.507; 95% CI, 1.292 to 1.758; p<0.001) were independent predictors of biochemical recurrence. CONCLUSIONS: Smaller prostate size was associated with increased risk of higher pT stage and positive surgical margin after radical prostatectomy. Also, prostate size less than 40 g was an independent prognostic factor for biochemical recurrence.

PURPOSE: The prognostic value of p53 remains controversial in transitional cell carcinomas of the bladder. Survivin, an inhibitor of apoptosis, is expressed in many human cancers. Recent studies have reported increased expression of survivin in superficial transitional cell carcinomas of the bladder. We investigated the expression of survivin and p53 and the clinical implications of this expression in superficial transitional cell carcinomas of the bladder. MATERIALS AND METHODS: Immunohistochemical staining of paraffin sections using a monoclonal antibody for survivin and p53 was performed in 82 cases of superficial transitional cell carcinomas of the bladder. Correlations between the expression of survivin and p53 and clinicopathological features, such as age, multiplicity of tumor, size, recurrence, and progression, were examined. RESULTS: Among 82 cases, positive survivin expression (greater than 20%) was observed in 59 cases. Positive p53 expression (greater than 20%) was observed in 46 cases. There were no significant differences in age, gender, multiplicity, tumor size, tumor grade, pT stage, recurrence, or progression-free survival between p53-positive and p53-negative groups (p>0.05). Also, there were no significant differences in age, gender, multiplicity, tumor size, tumor grade, or pT stage between survivin-positive and survivin-negative groups (p>0.05). However, recurrent-free and progression-free survivals were significantly lower in the survivin-positive group than in the survivin-negative group (p<0.05). CONCLUSIONS: The expression of survivin can be recommended as a useful marker for predicting disease recurrence and progression. Survivin may be superior to p53 as a prognostic factor in superficial transitional cell carcinoma of bladder.

PURPOSE: Acute or chronic prostatic inflammation exists to varying degrees in surgical specimens of prostates, extirpated for the treatment of benign prostatic hyperplasia(BPH). We investigated the relationship between acute urinary retention(AUR) and intraprostatic inflammation. MATERIALS AND METHODS: Between January 1997 and December 2006, 221 patients underwent transurethral resection of the prostate(TURP) for the treatment of BPH. The patients were divided into 2 groups based on the indication for surgery; an AUR group and a lower urinary tract symptoms (LUTS) group. The area of acute inflammation, the extent, and the aggressiveness of chronic inflammation were classified into four grades. The grades of inflammation, prostate volume, age, serum prostate-specific antigen(PSA), and prior medical treatment were compared between the two groups. All specimens were reviewed by one pathologist. RESULTS: The AUR group consisted of 106(47.9%) patients, and the LUTS group consisted of 115(52.1%) patients. There were no statistical differences between the two groups with respect to the mean values of the age, prostate size, and severity of chronic inflammation. There was a significant relationship between AUR and the areas of acute inflammation, and the extent of chronic inflammation(p=0.014 and p=0.003, respectively). The aggressiveness of chronic inflammation had no relationship with AUR (p=0.062). The serum PSA level was higher in the AUR group than the LUTS group(11.5 vs. 5.3ng/ml, respectively). CONCLUSIONS: The association for AUR with acute and chronic inflammation was stronger than that which existed with prostate size. Thus intraprostatic inflammation is an important risk factor in AUR.

Facial hyperhidrosis has a symptom of excessive sweating on the face with or without underlying disease. It can be surgically treated by video-assisted thoracic surgery (VATS). We encountered three cases of facial hyperhidrosis which we treated by VATS, which was performed by resection of the lower third of stellate ganglion and T2-T3 sympathetic ganglia with chains. Postoperative symptom was improved in all cases. There were no postoperative complications such as Horner's syndrome or postsympathectomy neuralgia.
