Big for the multidisciplinary surgeries like large locally invasive tumor resections that offer hope to patients that might otherwise be turned away.. Small for the minimally invasive techniques and nonintubated techniques that improve the lives of our patients – faster recoveries, less post-operative pain and shorter hospital stays..
In a previous post, we talked about the John Wayne principle and large surgical resections. We’ve talked about multi-disciplinary surgeries before, but during today’s presentation by Dr. Michael Harden of Australia, he presented several cases that highlighted the critical importance of large scale surgical resections for stage IIB and IIIA lung cancers.
Dr. Michael Harden is a cardiothoracic surgeon at the Royal North Shore Private Hospital in a suburb of Sydney, Australia.
During his lecture, on chest wall reconstruction for lung cancer, Dr. Harden presented several cases illustrating successful large scale resections. While each of the procedures was technically challenging due to the presence of very large, invasive tumors, these cases were complex for multiple reasons such as pre-operative radiation, morbid obesity and other serious co-morbidities.
In each of these cases, he highlighted the importance of multi-disciplinary involvement, from plastic surgery for free flap harvesting and revascularization, to cardiac surgery (for ECMO/ CPR) for resection of tumors involving the great vessels or spinal surgery for a case requiring an enbloc removal of a vertebral body for a very large paraglioma involving the lung, vertebra and rib – which was encroaching on the the spinal cord.
One of his more notable cases is mentioned below. This case illustrates the importance of innovation and consideration for patient’s quality of living as this surgical technique allowed this patient to return to his job as a truck driver. (Many of the more commonly used techniques to repair the sternum such as muscle flaps are not as conducive to this type of occupation which requires more than sitting behind the wheel.)
We have reached out to Dr. Harden for more information about his work.
Chest wall resection with pulmonary segmentectomy for metastatic breast cancer.
Title:Chest wall resection with pulmonary segmentectomy for metastatic breast cancer
Summary: Breast cancer remains the second leading cause of mortality in females in Mexico, aged 30 to 55, and is usually self-detected in later stages. Due to disparities in health care within the country, even patients with early detection may not receive optimal or timely treatment leading to more recurrent or metastatic disease. Surgery remains the best, but underutilized option for definitive treatment in patients with surgically resectable disease. In this case, a patient with advanced disease was successfully resected using a multi-disciplinary approach.

Announcement text: a multidisciplinary approach to recurrent metastatic breast cancer with chest wall resection and free flap graft creation.
Subject/ Classification terms: chest wall resection, rib resection, metastatic breast cancer, pulmonary segmentectomy, breast cancer in Mexico
Disclosures: The authors have no disclosures.
History/ Case Summary:
The patient was a 70-year-old Hispanic female with a past medical history significant for local breast cancer in the left breast, initially diagnosed in 1994. This was treated with chemotherapy and radiation. She was then maintained on tamoxifen until 2000. In 2011, she presented with a recurrent mass in the left breast. There was no other history of chronic or active medical conditions such as HTN, CAD or diabetes.
After referral to a surgical oncologist for further evaluation, patient underwent additional evaluation. A PET/ CT scan was positive for a metabolically active lesion in the left breast with an SUV of 9.6 with lytic lesions in anterior ribs with max SUV of 3.0. There was no evidence of distal metastasis to other organs including the brain, lungs, or abdominal cavity on PET or other diagnostic imaging. All pre-operative labs were within normal ranges including alk phos, and serum calcium.
After initial surgical evaluation, a multi-disciplinary surgical plan utilizing a general surgical oncologist, thoracic surgery and plastic surgery was devised for surgical resection of breast mass with rib resection and free flap creation.
Operative Course: The left breast including all skin, tissue and lymphatics was excised to the depth of the rib cage. Further dissection and resection of the anterior portion of ribs #2, 3 and #4 was completed.
Following rib resection, upon exploration of the left thoracic cavity, the patient was found to have a large greyish-white lesion, estimated at 3.5 cm in diameter in the left upper lobe. The lesion was hard, and located on the peripheral portion of the upper lobe. No additional lesions were found.
The decision to undertake pulmonary resection was based on the possibility of complete surgical resection of existing disease. At the time, a discussion was undertaken with the patient’s primary surgeon, and the thoracic surgeon on the feasibility of resection by lobectomy versus segmentectomy. The decision was made to proceed with a lung-sparing procedure as the patient’s baseline pulmonary function was not known.
Following successful lung resection and hemostasis, a 32 french chest tube was placed, and surgical mesh was placed for coverage of chest wall / rib defect. After mesh was sutured into place, the patient was re-positioned for harvesting of a free flap from the posterior chest. Abdominal free flap harvest was not undertaken due to patient anatomy. The plastic surgeon involved in the case, Dr. Nastia Gonzalez then proceeded with free flap grafting for breast reconstruction. There was no significant bleeding, hypoxia or hemodynamic instability intraoperatively.
The patient was successfully extubated at the conclusion of the case, and transferred to the post-operative care unit in stable condition. Post-operative course was uncomplicated with the chest tube removed on POD#3, and the patient discharged home on POD#5. The patient’s oxygen saturations were within the normal range (92% or above) and she was discharged home without supplemental oxygen.
Subsequent post-operative visit was uneventful with no evidence of infection, or impaired healing of the graft or harvest site. As of the date of publication, there has been no further evidence of recurrence or metastatic disease.
Conclusions: For patients with metastatic disease limited to adjacent and surgically resectable tissue, surgery remains the best option for longevity and overall survival. However, despite the available and use of advanced imaging studies, surgeons should prepare for and anticipate the possibility of discovery of evidence of additional disease. In this case, a more complete anatomic resection of the newly discovered lung lesion was hindered by the lack of pre-operative evaluation of pulmonary disease.
Chest wall resection and defect closure have been managed with a variety of techniques over the years, including muscle flaps, plastic ribcage creation, mesh closures for stabilization after rib resection (Khalil et al.). In this case, which required a radical mastectomy, surrounding musculature was removed for full resection. Tissue was harvested for free flap grafting but this gives lesser structure than attached muscle, so synthetic mesh was used.
Historically, hardware installation was plagued with a variety of problems including infection and erosion. However, preliminary reports of evolving hardware for oncologic chest resections may change closure techniques in the future (Fabre et al, 2012).
