Breast cancer-specific mortality after invasive local recurrence in patients with ductal carcinoma-in-situ of the breast.

BACKGROUND: Previous studies on the efficacy of primary treatments for ductal carcinoma-in-situ (DCIS) have focused on local recurrence rates. Our objective was to detail the outcomes of local invasive recurrence, distant recurrence, and breast cancer mortality in patients previously treated for DCIS. METHODS: Clinical, pathologic, and outcome data were collected prospectively for 1236 patients with pure DCIS accrued from 1972 through 2005. RESULTS: There were 150 recurrences (87 DCIS and 63 invasive). Invasive local recurrence after mastectomy was rare (0.5% of patients) and after breast preservation was more frequent (12.0% of patients). The 12-year probabilities of breast cancer-specific mortality after mastectomy and after breast preservation were 0.8% and 1.0%, respectively. The 12-year breast cancer-specific mortality and distant disease probability for the 63 patients with invasive recurrences were 12% and 15%, respectively. CONCLUSIONS: Regardless of initial treatment, most patients with invasive local recurrence after treatment for DCIS can be treated and cured.

Margin width as the sole determinant of local recurrence after breast conservation in patients with ductal carcinoma in situ of the breast.

BACKGROUND: A previous study showed a 3% local recurrence risk at 8 years in ductal carcinoma in situ (DCIS) patients treated with excision alone with surgical margins of 10 mm or greater. This study updates those data. METHODS: A total of 272 DCIS patients treated conservatively with 10 mm or greater margins were reviewed in a prospective database. RESULTS: Among 212 excision-alone patients, there were 9 DCIS and 3 invasive recurrences. The 12-year probability of any local recurrence was 13.9%; of invasive recurrence it was 3.4%. Among 60 excision plus radiation patients, there was 1 local (invasive) recurrence (P = .06). The 12-year probability of local recurrence was 2.5%. CONCLUSIONS: Local recurrence in DCIS patients treated with excision alone with margins of 10 mm or greater compares favorably with local recurrence in DCIS patients with nontransected margins and treated with postoperative radiation. The risk of invasive recurrence among widely excised DCIS patients is extremely low.

Efficacy of laparoscopic cholecystectomy in acalculous gallbladder disease: long-term follow-up.

OBJECTIVE: Our aim was to determine the efficacy of laparoscopic cholecystectomy in symptomatic patients with ultrasound negative and abnormal gallbladder ejection fractions; Patients with gallbladder ejection fractions less than 35% on hepatobiliary scan were offered laparoscopic cholecystectomy. METHODS: Between January 1995 and January 2001, 1564 patients underwent laparoscopic cholecystectomy at our institution: 256 were confirmed to have acalculous gallbladder disease by pathology report and reconfirmation of abnormal hepatobiliary scan data. A 30-day postoperative follow-up was obtained by retrospective medical record review. For this study, we contacted all 256 patients by mail questionnaire and followed up on nonresponders with telephone interviews; we also reviewed hospital records to verify preoperative symptom patterns. The survey was completed by 154 patients (60%): 48 (31%) by mail and 106 (69%) by telephone interviews. The study included 115 (75%) female and 39 (25%) male patients, and the average age was 42 years (range, 13 to 95). All hepatobiliary laboratory parameters were normal pre- and postoperatively. The survey was completed in December 2001, 1 to 5 years postoperatively (mean 3 years). RESULTS: Preoperatively, 142 patients (92%) had right upper quadrant pain, 114 (74%) had nausea, 88 (57%) had vomiting, 120 (73%) had heartburn, and 118 (77%) had food intolerance. In a 30-day postoperative period, these numbers had reduced to 48 (37%), 14 (90%), 8 (5%), 22 (14%), and 34 (22%), respectively. had laparoscopic cholecystectomy, and 95% stated that they would recommend laparoscopic cholecystectomy to other patients. CONCLUSION: This study shows that patients with acalculous gallbladder disease benefit from laparoscopic cholecystectomy.
