We report a case of a solitary liver metastasis from breast cancer in a 65-year-old woman. The patient underwent a mastectomy and axillary lymph node clearance for right breast cancer in 1990. A solitary metastasis was found in the left lobe of the liver by ultrasonography, 20 years after the initial mastectomy. A left lateral segmentectomy was performed in January 2011 and adjuvant hormonal therapy was also initiated. At present, she remains disease free.This case demonstrates the implementation of liver resection to provide an effective treatment for metachronous metastatic breast cancer. We encourage surgeons to offer suitable patients this surgical treatment option, which is shown to provide a survival benefit.
KEYWORDSBreast cancer -Liver metastases -Liver resection Breast cancer is the most common cancer in females. A fifth of breast cancer patients have metastatic disease and in more than half of these patients, the liver is involved.
1Metastatic disease is associated with a shorter median survival time and, currently, the mainstay of treatment is medical, in the form of hormonal treatment and chemotherapy. However, recent studies worldwide have shown that in highly selected patients, surgical resection of liver metastases can have a significant survival benefit.
Case HistoryA 65-year-old woman was found to have mildly deranged liver function tests (alanine transaminase 145iu/l, gammaglutamyltransferase 69iu/l) on a routine health check-up. She had a history of right-sided breast cancer, which had been treated with a mastectomy, axillary lymph node clearance and adjuvant hormonal therapy 20 years earlier. Following this, she had multiple reconstructive surgeries to both breasts, resulting in a deep inferior epigastric tissue reconstruction of the right breast and an implant reconstruction of the left breast.There was no history of weight loss, abdominal pain or distension, loss of appetite or any sinister symptoms. Physical examination was unremarkable with no discernible anaemia, jaundice or lymphadenopathy.Ultrasonography of the abdomen revealed a solitary 1.5cm heterogeneous lesion in the left lobe of the liver with no other demonstrable pathology. Further imaging with computed tomography of thorax, abdomen and pelvis (Fig 1) confirmed the lesion was localised to segment 2 of the liver, and there was no extrahepatic disease.Initially, careful surveillance of the lesion was undertaken with repeat ultrasonography (Fig 2) and magnetic resonance imaging (MRI) after two months. Repeat imaging demonstrated enlargement of the lesion to 1.8cm.At this stage, the patient was referred to a regional hepatobiliary surgical unit. After satisfactory anaesthetic assessment, she underwent a left lateral segmentectomy to resect this solitary liver lesion. Histology confirmed that this was a breast metastasis and that the resection was successful (R0), achieving disease free clearance margins. Adjuvant treatment was with an aromatase inhibitor (letrozole) owing to positive oestrogen receptor status. At the time o...
