Purpose: Local recurrence of renal cell carcinoma in the renal fossa after complete radical nephrectomy is uncommon. We characterize and determine outcome in a small subset of patients.Materials and Methods: From 1970 to 1998 the incidence of isolated renal bed recurrence among 1,737 T1-3N0M0 unilateral nephrectomy cases was 1.8% (standard error [SE] 0.4) at 5 years. There were 30 patients in whom isolated local fossa carcinoma recurred after complete radical nephrectomy without evidence of metastatic disease. Patients with any nodal involvement at radical nephrectomy were excluded from study as were those who had undergone any form of partial nephrectomy. Patient charts were reviewed for clinical presentation, stage, treatment, development of metastatic disease and survival. Pathological stage was assigned according to the 1997 TNM staging system. Recurrence was identified in 12 (40%) patients during routine followup and the remaining 18 (60%) presented with symptoms related to the recurrent tumor. Patie...

PURPOSE: A significant number of patients with stage T1 bladder carcinoma are at risk for cancer progression. We sought to identify factors associated with cancer progression in a series of patients with stage T1 bladder carcinoma treated with a contemporary therapeutic approach. PATIENTS AND METHODS: The study population consisted of 83 consecutive patients in whom stage T1 bladder carcinoma was diagnosed at the Mayo Clinic between 1987 and 1992. All patients underwent transurethral resection of the bladder (TURB) and had histologic confirmation of the diagnosis. The mean age was 71 years (range, 47 to 94 years). The male-to-female ratio was 3.9:1. The mean length of follow-up was 5.2 years (range, 1 day to 10.4 years). The depth of lamina propria invasion in the TURB specimens was measured with an ocular micrometer. Cancer progression was defined as the development of muscle-invasive or more advanced stage carcinoma, distant metastasis, or death from bladder cancer. RESULTS: The overall 5- and 7-year progression-free survival rates were 82% and 80%, respectively. The depth of invasion in the TURB specimens was associated with cancer progression (hazards ratio, 1.6 for doubling of depth of invasion; 95% confidence interval, 1.03 to 2.4; P = .037). The 5-year progression-free survival rate for patients with depth of invasion of ≥ 1.5 mm was 67%, compared with 93% for those with depth of invasion of less than 1.5 mm (P = .009). No other variable, including age, sex, tobacco use, alcohol use, the presence of carcinoma-in-situ, histologic grade, lymphocytic infiltration, or muscularis mucosae invasion, was associated with cancer progression. CONCLUSION: The depth of invasion in the TURB specimens, measured with a micrometer, is predictive of cancer progression in patients with stage T1 bladder carcinoma.

Background. Eighty-five percent of all Merkel cell carcinomas appear on sun-exposed areas, with 50% to 55% occurring on the head and neck. Methods. A chart review was performed on 22 patients treated for Merkel cell carcinoma of the head and neck between 1981 and 1998. Results. Fifteen patients were men (68%). The average age at operation was 69.9 years (range, 24-84 years). The average duration of follow-up was 3.6 years (range, 3 days-8.6 years). Overall survival at 1, 2, and 3 years postoperatively was 78%, 68%, and 68%, respectively. The only independent predictor of survival was the type of surgical therapy. All patients who underwent wide local excision (WLE) of the primary tumor with dissection of the lymphatic drainage basin were alive at 2 years as opposed to 68% who had WLE alone and 33% who had Mohs surgery. Conclusions. WLE and dissection of the lymphatic drainage basin provided the best overall survival.

Background: We describe the long-term outcome of repair of partial atrioventricular septal defect by determining the rates of survival, reoperation, and occurrence of left atrioventricular valve regurgitation, left atrioventricular valve stenosis, left ventricular outflow tract obstruction, and arrhythmia. Methods: We studied 334 patients who underwent repair of partial atrioventricular septal defect before 1995. Results: The 30-day and 5-, 10-, 20-, and 40-year survival were 98%, 94%, 93%, 87%, and 76%, respectively. Closure of the left atrioventricular valve cleft (P = .03) and age less than 20 years at operation (P < .001) were associated with better survival. Reoperation was performed for 38 patients (11%). Repair of residual/recurrent left atrioventricular valve regurgitation or stenosis was the most common reason for reoperation. Left ventricular outflow tract obstruction occurred in 36 patients, and 7 patients underwent reoperation to relieve this obstruction. Supraventricular arrhythmias were observed in 58 patients (16%) after the operation. Supraventricular arrhythmias increased with increasing age at primary operation (P = .001). Complete atrioventricular block occurred in 9 patients (3%). Permanent pacemakers were implanted in 11 patients. Conclusions: Long-term survival after repair of partial atrioventricular septal defect is good. It is important to close the cleft in the left atrioventricular valve. Reoperation for persistent or recurrent left atrioventricular valve malfunction and relief of left ventricular outflow tract obstruction is necessary in approximately 11% of patients.
