Previous studies have shown that 4-54% of breast lesions reported on core biopsies as atypical ductal hyperplasia (ADH) are upgraded on further excision to ductal carcinoma in situ (DCIS) or invasive carcinoma. We evaluated the rate of upgrading ADH to carcinoma at surgery for ADH diagnosed by percutaneous biopsy, and examined characteristics associated with malignancy. We identified 13,488 consecutive biopsies conducted at one center over a nine-year period. A total of 422 biopsies with ADH in 415 patients were included. DCIS or invasive carcinoma was found in 132 cases (31.3% upgrading). Multivariate model revealed that ipsilateral breast symptoms, mammographic lesion other than microcalcifications alone, 14G core needle biopsy, papilloma co-diagnosis, severe ADH and pathologists with lower volume of ADH diagnosis were factors statistically associated with malignancy. However, no subgroups were identified for safe clinical-only follow-up. Surgery is recommended in all cases of ADH diagnosed by percutaneous breast biopsy.

Pulmonary metastasectomy is a curative option for selected patients with cancer spread to the lungs. Complete surgical removal of pulmonary metastases can improve survival and is recommended under certain criteria. Specific issues that require consideration in a multidisciplinary setting when planning pulmonary metastasectomy include: adherence to established indications for resection, the surgical strategy including the use of minimally invasive techniques, pulmonary parenchyma preservation, and the role of lymphadenectomy.

Anticancer agents targeting circulating vascular endothelial growth factor (VEGF) (e.g., bevacizumab and aflibercept) are strong angiogenesis inhibitors. As such, they may hamper the healing process, notably in the early postoperative period. Whether antiangiogenic agents may be associated with late postoperative healing complications is less known. We reviewed three cases of patients with anastomotic complications under antiangiogenic treatment occurring more than 1 year after initial surgery and we conducted a review of the literature. We report the first case of delayed anastomotic leakage which occurred under aflibercept therapy 13 months after a bilioenteric anastomosis and two cases of delayed rectal anastomotic complications associated with bevacizumab treatment 18 and 78 months after surgery. Fifteen similar cases of late gastrointestinal anastomotic complications were found in the English literature. Antiangiogenic agents are probably not deleterious to a healed wound. However, they appear to be associated with an increased risk of complications in a subgroup of patients. According to the 18 cases reported, the main risk factors appear to be low anterior resection for rectal cancer, perioperative radiotherapy, and early postoperative leak which heals through the formation of abundant and hypervascularized granulation tissue.

HAI of oxaliplatin with systemic 5-Fluorouracil and leucovorin offers a second chance to remove initially unresectable isolated colorectal liver metastases in 24% of patients, and appears to be more efficient when performed as first-line therapy. Long-term overall survival can be obtained with this approach.
