Breast cancer electron intraoperative radiotherapy: assessment of preoperative selection factors from a retrospective analysis of 758 patients and review of literature.

PURPOSE: To report our experience with full-dose 21 Gy IORT in early breast cancer patients after breast-conserving surgery to define most important selection factors. METHODS: Seven hundred and fifty eight patients, subjected to conserving surgery and IORT, were retrospectively analyzed evaluating most important clinical outcomes. RESULTS: Median follow up was 5.2 years. Results from Cox analyses defined 2 groups of patients, "suitable" (age > 50 years, non lobular histology, tumour size ≤ 2 cm, pN0 or pNmic, ki67 ≤ 20%, non triple negative receptor status and G1-G2) and "unsuitable" for IORT, with a higher rate of breast related events moving from "suitable" to "unsuitable" group. The 5 year rate of IBR is 1.8% in suitable group with significant differences versus unsuitable (1.8 vs. 11.6%, p < 0.005). Same differences between two groups were evidenced in true local relapse (0.6 vs. 6.9%, p < 0.005) and in new ipsilateral BC (1.1 vs. 4.7%, p < 0.015). CONCLUSIONS: In our current practice we consider the following preoperative factors to select patients suitable for IORT: age > 50 years, absence of lobular histology, tumor size ≤ 2 cm, pN0 or pNmic, according to APBI consensus statement, including also ki67 ≤ 20%, non triple negative receptor status and G1-G2.

Axillary recurrence in sentinel lymph node-negative breast cancer patients.

BACKGROUND: Sentinel lymph node biopsy (SLNB) was developed to axillary lymph node dissection (ALND) in the treatment of breast cancer. SLNB is predictive of axillary node status. Major concern is the occurrence of a false-negative SLN. Purpose of this study is to determine the rate of axillary recurrence in our series of unselected patients. PATIENTS AND METHODS: All patients with a negative SLNB from November 1999 to December 2006 have been treated and followed at our unit. Information on patients' characteristics, treatment and follow-up has been collected. RESULTS: Eight-hundred and four patients with negative SLNB did not receive ALND. After a median follow-up of 38.8 months, 21 patients had distant metastases, four had axillary relapse, nine had an in-breast recurrence and two had both. All patients with axillary recurrence received axillary dissection and systemic adjuvant therapy. They are all presently alive and free from disease. CONCLUSION: Data from this series, the largest from a general hospital, showed that isolated axillary node recurrence after negative SLNB is rare (<1%) and comparable with those reported from referral cancer institutions. We confirm that SLNB for the treatment of early breast cancer patients of a community-based hospital is safe and reliable.

[A gastrocutaneous fistula secondary to the percutaneous drainage of a pancreatic abscess. A case report]. / Fistola gastrocutanea secondaria a drenaggio percutaneo di ascesso pancreatico. Descrizione di un caso.

Pancreatic abscesses are a frequent complication of acute pancreatitis and their percutaneous drainage is usually accepted. A 76 years-old male patient admitted for acute pancreatitis (Ranson 3 at admission) has been treated with conservative therapy and percutaneous US directed drainage of the abscess, located between the tail of the pancreas and the gastric fundus. This kind of drainage was able to empty the abscess satisfactorily but it caused the onset of a gastrocutaneous fistula. This one was sutured on the gastric side by metal clips placed by gastroscopy. The patient was discharged on the 60th day in a good condition. An X-ray investigation with gastrografine before the drainage removal is therefore recommended.

Intraoperative colonic lavage in emergency surgical treatment of left-sided colonic obstruction.

PURPOSE: The study contained herein was undertaken to verify if immediate resection with anastomosis with on-site lavage in emergency treatment of left colon obstruction is a safe alternative to the multistage procedure, to look for solutions to practical problems outlined by previous authors, and to check the hospital stay. METHOD: Between 1991 and 1995, all patients (61) admitted with left colon obstruction were treated with intraoperative colonic lavage and primary anastomosis. Personal development of Dudley's technique is reported. Complications and mortality are pointed out. Later, endoscopy was performed to check the status of all survivors. RESULT: Low mortality (2 percent) and major complication rates (3 percent) and short hospital stay (11 days, except for patients with major complications) are reported in our series. CONCLUSION: One-stage surgery with intraoperative lavage is a safe procedure. Patients have a better quality of life (no stoma occurred) with an effective cost-savings.
