Cardiac Sparing Breast Radiation Techniques

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Multiple techniques have been used to aid in cardiac sparing, including:
    • Assisted breathing control
    • Accelerated partial breast irradiation
    • Intensity-modulated radiation therapy
    • Prone positioning
  • A study from Mulliez et al:
    • Found that prone technique in conjunction with respiratory gating:
      • Was associated with a reduction in mean heart dose, as well as dose to the left anterior descending coronary artery
  • At this time, there are limited data regarding long-term cardiac outcomes (e.g., myocardial infarctions) with any cardiac-sparing technique:
    • Due to the length of follow-up required
  • Outcomes with prone breast irradiation have demonstrated:
    • Low rates of local recurrence
    • Excellent cosmetic outcomes
    • No suggestion of higher rates of skin toxicity
    • Lower doses to the lungs and heart
    • No suggestion of higher rates of pneumonitis

Complications Following Breast Reconstruction

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Performing an immediate breast reconstruction with a tissue expander or breast implant:
    • Carries a higher complication rate than a mastectomy alone
  • Surgical complications and delayed wound healing:
    • May lead to a delay in adjuvant radiation therapy
  • Obesity with a BMI >30:
    • Increases complication rates leading to adjuvant radiation therapy delays
  • Age over 50 has also been implicated to increase post-operative complications which may be related to other pre-existing comorbidities that occur with advancing age

Smoking and Obesity have been shown to significantly increase risk of complications in patients undergoing autologous tissue breast reconstruction?

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Smoking and obesity:
    • Increase the risk of complications for all types of breast reconstruction:
      • Whether with implant or flap
  • Smoking and obesity:
    • Are therefore considered a relative contraindication to breast reconstruction:
      • Patients should be made aware of increased rates of wound healing complications and partial or complete flap failure:
        • Among smokers and obese patients
  • Alcohol intake:
    • Has not been shown to be a significant risk factor for complication with breast reconstruction
  • While age greater than 70 alone has not been shown to increase risk of complication in patients undergoing autologous tissue breast reconstruction:
    • Patients over 70 years may be more likely to have other comorbidities
  • Patients undergoing immediate autologous breast reconstruction following neoadjuvant chemotherapy have a similar complication and reoperation rates to patients not receiving neoadjuvant chemotherapy

Expander / Implant Breast Reconstruction Complication Rate

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Expander / implant breast reconstruction:
    • Has been shown to have a lower risk of overall complication compared to autologous reconstruction techniques:
      • According Bennet et al:
        • The overall complication rate for breast reconstruction was 33%
  • Expander / implant reconstruction:
    • Had the lowest risk at 26.6% compared to autologous flap techniques:
      • Which were reported to have complication rates of 36% to 74%
  • When the autologous techniques are compared:
    • The fTRAM flap had the lowest risk of complication:
      • At 35.8%
  • Latissimus dorsi flap was found to have complication rate of 39.4%:
    • Followed by pTRAM at 41.2%
  • The technique with the highest risk of complications were deep inferior epigastric artery perforator (DIEP) flap at 47.4%, and the superficial inferior epigastric artery perforator flap at 74%

Oncoplastic Breast Surgery

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Performing a partial mastectomy using an oncoplastic approach:
    • Has been shown to be safe with the additional benefit of larger tissue volume resection, lower re-excision rates, and low rates of disease recurrence while minimizing cosmetic deformity of the breast
  • Proximity of tumor to the nipple areolar complex:
    • Is not an absolute indication for mastectomy
  • Neoadjuvant chemotherapy:
    • Has not been shown to improve overall breast cancer survival
  • Obesity and diabetes:
    • Have not been shown to be independent risk factors for complication in patients undergoing oncoplastic surgery:
      • Therefore should not be contraindications for consideration of oncoplastic surgery

Oncoplastic Breast Surgery (OBS)

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Oncoplastic breast surgery (OBS):
    • Combines principles of oncology and plastic surgery:
      • Toward achieving sound oncological and aesthetically pleasant results for breast tumors amenable to segmental mastectomies in patients with a favorable tumor to breast volume
  • OBS expands the indications for breast conservation:
    • Allowing the resection of much larger tumors, and is now an option for the surgical treatment of tumors larger than 4 cm and locally advanced cancers especially in large-breasted patients
    • When compared to conventional breast-conserving surgery (BCS):
      • OBS commonly results in higher specimen resection volumes and lower re-excision rates 
    • OBS does not eliminate or change the need for adjuvant therapies; most, if not all, patients undergoing segmental mastectomy for invasive breast cancers will benefit from adjuvant radiation therapy
    • OBS training is widely accepted as a prerequisite for performing these surgeries and should be represented in any multidisciplinary team, treating breast cancer and offering OBS: 
      • While no definitive test exists to assess aesthetic results and compare these between OBS and BCS for matched defects, most studies report favorable aesthetic results following OPS, in the majority of patients

Work-up of Breast Implant-Associated Anaplastic Large Cel Lymphoma

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL):
    • Is an uncommon lymphoma that has only been reported in patients with a history of a textured breast implant device
  • Suggested theories of the cause of BIA-ALCL include:
    • Textured implant particulate
    • Chronic allergic inflammation, and / or response to a biofilm
  • Following National Comprehensive Cancer Network (NCCN) guidelines:
    • A swollen breast can be evaluated with ultrasound for either a:
      • Fluid collection
      • Capsular mass
      • Lymph node swelling
    • Fluid collections should be aspirated percutaneously:
      • A minimum of 20 ml but ideally as much fluid available should be sent for:
        • CD30 immunohistochemistry
        • Cell block cytology and flow cytometry evaluation and labeled to “rule out BIA-ALCL
      • CD30 testing is critical to direct pathologists
      • Efforts should be made to establish a diagnosis:
        • Prior to any surgical intervention

Fat Grafting in After Breast Cancer Surgery

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Autologous fat grafting:
    • Is a procedure to transfer fat from one part of the patient’s body to another without requiring microvascular anastomosis
    • The graft initially takes similar to a skin graft, depending on the surrounding tissue bed before new blood vessels form
    • The grafted tissue is at risk for ischemia or fat necrosis:
      • As a result, there may be both palpable changes (e.g., cyst) or radiographic changes (e.g., calcifications) following fat grafting:
        • These have benign appearance on mammogram and are generally distinguishable from malignancy but may prompt additional imaging
  • Retrospective data suggest fat grafting does not interfere with cancer screening or detection
  • Fat grafting can be performed for all types of reconstruction, including primary defects as in lumpectomy, asymmetry, contour changes after radiation, or contour irregularity over an implant or tissue flap:
    • To date, there have been no clinical studies that demonstrate an increase in local regional recurrence in patients who have undergone fat grafting after breast cancer treatment
  • There is debate as to whether there is an ideal time to perform fat grafting:
    • But it is not routinely performed at the same time as lumpectomy or mastectomy:
      • Especially if radiation is indicated, as the tissue grafts will be susceptible to radiation injury
  • Finally, graft resorption is possible following the procedure, and therefore patients should be counseled that more than one operation may be necessary to achieve the desired result

Innervation of the Nipple Areolar Complex (NAC):

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • The innervation of the nipple areolar complex (NAC):
    • Is from the anterior and lateral branches of the 3rd, 4th, and 5th intercostal nerves:
      • Of which the lateral cutaneous branch of the 4th intercostal is dominant
  • This nerve has the greatest risk of injury during a resection of the central lower pole of the breast:
    • A superior pedicle, with resection of the lower pole:
      • Has the highest incidence of NAC sensory compromise
    • All patients should be advised that there is a risk of permanent loss of sensation
