Introduction Adenoid cystic carcinoma is an uncommon type of breast cancer. There are limited data about its epidemiology, tumor characteristics, and outcomes. Using a large, population-based database, this study aims to identify specific characteristics of patients with adenoid cystic breast cancer, investigate its natural history, and determine its long-term prognosis. Methods The California Cancer Registry (CCR), a population-based registry, was reviewed from the years 1988 to 2006. The data were analyzed with relation to patient age, tumor size and stage, and overall survival. Relative cumulative actuarial survival was determined using the Berkson-Gage life table method. Results A total of 244 cases of invasive adenoid cystic cancer were identified in women during this time period. The patients’ median age was 61.9 years. Most cases were diagnosed in non-Hispanic White women (82%, n=200), followed by African-American (6%, n=15), Asian/Pacific-Islander (5.7%, n=14) and Hispanic women (4.4%, n=12). The remainder of the patients was of unknown or other ethnicity. Tumors were between 1 and 140 mm in size. At the time of diagnosis, 92% (n=225) of patients had localized disease, 5% (n=12) of patients had regional disease, and even fewer (n=7) had either distant or unknown staged disease. Lymph node involvement was not present in any tumors smaller than 1.4 cm. The relative cumulative survival of patients with adenoid cystic breast carcinoma was 95.6% at 5 years and 94.9% at 10 years. Conclusion Adenoid cystic carcinoma of the breast is a rare disease with an overall good prognosis. Knowing that this cancer usually presents as localized disease, with lymph node involvement seen only with larger tumors, can help clinicians plan the operative management of these tumors.

BackgroundSingle-port and incisionless surgical approaches hold the promise of fewer complications, reduced pain, faster recovery, and improved cosmesis compared with traditional open or laparoscopic approaches. The ability to select an access approach (i.e., endolumenal, single-port, transvaginal, or transgastric) with one platform may be important to optimization of individual patient results. The authors report their results using these four separate surgical approaches tailored to three different therapeutic procedures, all with the use of a single flexible platform, the Incisionless Operating Platform (IOP).MethodsAfter institutional review board approval, the IOP was used to perform nine cholecystectomies via transvaginal (TV) (n = 4), transgastric (TG) (n = 4), and single-port transumbilical (TU) (n = 1) access. Two appendectomies were performed via TG access. Endolumenal access was used for 18 gastric pouch and stoma reductions after Roux-en-Y gastric bypass. The TG and TV procedures involved the use of one to three trocars. The recorded data included safety, procedural success, operative time, patient pain assessment (on a 0–10 scale) at discharge, and length of hospital stay. ResultsProcedural success was achieved for 16 of 18 endolumenal procedures, 1 of 1 single-port procedure, and 10 of 10 NOTES procedures. For 5 of 10 NOTES procedures, only one small trocar was required. The mean operative times were 79 min for pouch with stoma reduction, 171 min for cholecystectomy, and 274 min for appendectomy. Of 29 patients, 27 were discharged in 24 h or less. The average pain scores were 0.44 for pouch with stoma reduction, 1.3 for cholecystectomy, and 2.5 for appendectomy. No significant complications occurred. The ergonomics of IOP allowed the surgeon to interface with the system using an endoscopic or laparoscopic orientation.ConclusionAvailability of a multifunctional, flexible surgery platform provides a choice of a single-port or incisionless surgical approach with the potential to reduce complications, pain, and recovery time while improving cosmesis.
