Study No of tumors Pathology Tumor size Complete ablation Cosmetic results Complications Image guidance
Huber et al. (2001) [55] 1 Invasive ductal carcinoma 2.2 cm Surgical resection in the treated part of the tumor, cells were partly necrotic and mostly sublethally damaged Good The skin over the treated area did not exhibit any ultrasound-related visible changes MRI
Gianfelice et al. (2003) [56] 12 Invasive ductal carcinoma (n=10), invasive lobular carcinoma (n=1), adenocarcinoma (n=1) All tumors <3.5 cm Routine segmental tumor resection, complete necrosis (33%, 4/12) Minor skin burns (16.6%, 2/12), tenderness around the treatment zone (25%, 3/12) MRI
Gianfelice et al. (2003) [57] 17 Invasive ductal carcinoma (n = 14), adenocarcinoma (n = 2), invasive lobular carcinoma (n = 1) < 3.5 cm Complete necrosis (23%, 4/17), residual cancer volume below 10% (53%, 9/17); residual cancer volume between 30% and 75% (23%, 4/17) None mentioned; routine segmental resection None mentioned MRI
Gianfelice et al. (2003)[61] 24 Biopsy-proven breast carcinoma All tumors < 3.5 cm Surgical resection, complete necrosis (79%, 19/24) Not mentioned Two degree skin burn (4%, 1/24) MRI
Zippel et al. (2005)[58] 10 Infiltrating breast carcinoma All tumors < 3 cm Surgical resection; complete necrosis (20%, 2/10). Microscopic foci of residual tumor (20%, 2/10); 10% residual tumor (30%, 3/10) and 10%-30% residual tumor (30%, 3/10) Acceptable cosmetic results (10%, 1/10) No infection; two degree skin burn (20%, 2/10) MRI
Khiat et al.(2006)[59] 26 Invasive ductal carcinoma (n=25), infiltrating lobular carcinoma (n=1) < 3.5 cm Surgical resection; complete necrosis (28%, 7/26); less than 10% residual tumor (42%, 11/26) No reports No reports MRI
Furusawa et al. (2006)[60] 30 Invasive ductal carcinoma (n=25), invasive mucinous adenocarcinoma (n=1), DCIS (n=2), intraductal carcinoma(n=1), noninvasive ductal carcinoma (n=1) All tumors < 3 cm Mean necrosis rate of breast tumors 96.9%. Complete necrosis (50%,15/30) Between 95% to 100% necrosis (36%,12/30) A reliable replacement for lumpectomy Three degree skin burn (3%, 1/30); One required treatment termination due to pain, abdominal and breast skin redness (3%, 1/30) MRI
Furusawa et al.(2007)[62] 21 Invasive or noninvasive ductal carcinoma 0.5 to 5 cm Mean follow-up 14 months; complete necrosis (95%, 20/21); one recurrence (5%) Dimple on the skin (4.5%, 1/21) Skin burns (9%, 2/21) MRI
Wu et al. (2003) [43] 23 Invasive breast cancer (n=21) < 6 cm Surgical resection; complete necrosis (100%, 23/23) No changes of mammary shape Minimal skin burn (3%, 1/23); 5 patients needed oral analgesics Ultrasound
Wu et al. (2005) [45] 23 Invasive breast cancer (n=21), noninvasive breast cancer (n =1) All tumors < 5 cm No surgical resection; 100% complete necrosis (100%, 23/23); local recurrence (9%, 2/23) after 18 and 22 months, respectively Good to excellent in 94%, acceptable in 6% Six patients needed oral analgesics (18%, 6/23). No skin burn, bleeding, or infection Ultrasound
Kim et al. (2010)[54] 6 Invasive ductal carcinoma 1.2 to 3.7 cm Surgical resection and biopsy; complete necrosis (66%, 4/6) Skin thickening and trabecular thickening Mammary edema and injury to the pectoralis major muscle (100%, 6/6), disappearing 6 months later. Ultrasound
Total 2001-2007 173 20%-100% Excellent in most patients skin burn at least (4.5%, 8/176)
