Coverage policy

Select Health of South Carolina considers the use of radiofrequency ablation to be clinically proven and,

therefore, medically necessary in members aged 18 years and older for treatment of tumors that are

accessible to the procedure and at least 1 cm from major organs or structures that could be injured by

thermal conduction, including:

Hepatocellular carcinoma confirmed by biopsy or imaging (National Comprehensive Care

Network [NCCN], 2017a; Interqual, 2016; American College of Radiology [ACR], 2015):

- Bridge therapy to maintain candidacy for liver transplantation.

- When a member is medically inoperable, ineligible for liver transplantation, or

refuses resection, and has either:

Barcelona Clinic Liver Cancer early-stage (defined as a single tumor < 5 cm at

its longest axis, or two or three tumors each ≤ 3 cm, Child-Pugh A-B, and

performance status 0) with no extrahepatic disease.

Barcelona Clinic Liver Cancer intermediate stage (defined as a single large

tumor or multinodular disease, preserved liver function, and no

extrahepatic spread or macrovascular invasion) and tumors have been

downsized to a single tumor ≤ 5 cm or two to three tumors each ≤ 3 cm

following transarterial therapy.

Liver metastases confirmed by biopsy or imaging when all of the following criteria are met

(NCCN, 2017a, b, c, f; ACR, 2015; Interqual, 2016):

- Tumors ≤ 5 cm.

- Ineligible for surgical resection.

- For members with colorectal cancer, metastases are confined to the liver.

- For members with neuroendocrine tumor involvement, persistent symptoms after

medical treatment with somatostatin analogs.

Renal cell carcinoma when all of the following criteria are met (NCCN, 2018; Interqual,

2017):

- Stage I (T1a). - Confirmed by biopsy. - Single tumor > 1 cm and ≤ 4 cm. - No metastasis.

Symptomatic osteolytic bone metastases in members who have failed, or are poor

candidates for, standard pain treatments such as radiation or opioids (Rosian, 2017;

Rosenthal, 2012; Warmuth, 2012).

Primary or secondary lung cancers (NCCN, 2018; National Institute for Health and Care

Excellence [NICE], 2010a):

- Early-stage, resectable (stage I-II, N0) non-small cell lung cancer in members who

are medically inoperable or refuse surgery (Bi, 2016; Sher, 2011).

- For members: who are not candidates for stereotactic ablative radiotherapy,

external beam radiation therapy, or sublobar resection; who have failed stereotactic

ablative radiotherapy; or for whom local control may not be the highest priority

(NCCN, 2018).

Primary therapy for:

Intestinal metaplasia (Barrett’s esophagus) (Almeida, 2016; NICE, 2014; NICE,

2010b).

Early-stage esophageal or esophagogastric cancer (pTis, pT1a, pTibN0) with or

without endoscopic resection (NCCN, 2017d).

After esophageal resection for residual or recurrent high-grade or low-grade esophageal

dysplasia (NCCN, 2017d; Evans, 2013).

Thyroid cancer for locoregional control when standard therapy (e.g., surgery or local

therapies) is contraindicated, has failed, or is refused (NCCN, 2017e; NICE, 2016).

Metastatic (synchronous stage IV) soft tissue sarcoma of the trunk, extremity, head, or neck

(NCCN, 2018c; Gronchi, 2016):

- Primary local therapy when confined to a single organ and limited tumor bulk.

- Palliative therapy for symptomatic disseminated disease.

Select Health of South Carolina considers the use of radiofrequency ablation to be clinically proven and,

therefore, medically necessary for treatment of osteoid osteomas that cannot be managed successfully

with medical treatment, are accessible to the procedure, and at least 1 cm from major organs or

structures that could be injured by thermal conduction (Rosenthal, 2012; Warmuth, 2012).

Limitations:

The effectiveness of radiofrequency ablation for indications other than the ones listed above has not

been established. Radiofrequency ablation may be considered on a case-by-case basis for removal of

other primary or metastatic malignant neoplasms when either:

Removal of the neoplasm may be curative and the member is unable to tolerate or refuses

surgical resection or radiation therapy.

Palliative debulking or complete removal may relieve symptoms.

Relative contraindications include (NCCN, 2017a, b, c; Interqual, 2016):

Ablative margins measuring less than 1 cm (i.e., tumors should be located at least 1 cm from

critical structures or vessels to achieve complete tumor destruction), except in cases of

palliation or debulking.

More than three tumors per organ. However, the number of lesions should not be

considered an absolute contraindication to radiofrequency ablation if successful treatment

of all metastatic deposits can be accomplished.

Untreatable or unmanageable coagulopathy is an absolute contraindication to radiofrequency ablation.

Alternative covered services:

Standard of care specific to each tumor.

Background

Radiofrequency ablation applies heat using high-frequency alternating current via electrodes placed

within the tissue to induce tissue coagulation and cell death (Friedman, 2004). It is one of several types

of ablative therapies used to treat a wide range of cardiac, neurologic, vascular, and oncologic

conditions. The U.S. Food and Drug Administration (FDA) classifies radiofrequency ablation as an

electrosurgical, cutting, and coagulation device with 510(k) marketing submission requirements (FDA,

2017).

Radiofrequency ablation can be applied percutaneously, laparoscopically, or at open surgery. The choice

of technique will depend on: the patient’s condition; tumor size, number, location, and growth pattern;

and operator and local practice patterns. It may be performed in outpatient or inpatient settings under

general anesthesia, conscious sedation, or deep sedation (Friedman, 2004).

Page 4: Radiofrequency ablation of tumors...liver is a common site for metastasis from solid tumors, and many are unsuitable for surgical excision because of their number, distribution, or

Percutaneous radiofrequency ablation is a minimally invasive, repeatable procedure performed under

radiologic guidance. The percutaneous approach requires that tumors not lie adjacent to other organs

or vessels that could be injured by thermal conduction. Surgical approaches allow a more accurate

evaluation of disease in and around the organ and present less risk to adjacent structures. The open

approach allows for concurrent combination therapies, such as resection and placement of pumps for

regional chemotherapy (Friedman, 2004).

This policy will focus on radiofrequency ablation as treatment for tumors and pre-malignant conditions,

excluding treatment of uterine fibroids. See Clinical policy #12.03.04 Radiofrequency ablation of uterine

fibroids.

Searches

Select Health of South Carolina searched PubMed and the databases of:

UK National Health Services Centre for Reviews and Dissemination.

Agency for Healthcare Research and Quality’s National Guideline Clearinghouse and other

evidence-based practice centers.

The Centers for Medicare & Medicaid Services (CMS).

We conducted searches on January 8, 2018. Search terms were: "Catheter Ablation" (MeSH),

"Neoplasms" (MeSH), and the free text terms “radiofrequency ablation” and “RFA.”

We included:

Systematic reviews, which pool results from multiple studies to achieve larger sample sizes

and greater precision of effect estimation than in smaller primary studies. Systematic

reviews use predetermined transparent methods to minimize bias, effectively treating the

review as a scientific endeavor, and are thus rated highest in evidence-grading hierarchies.

Guidelines based on systematic reviews.

Economic analyses, such as cost-effectiveness, and benefit or utility studies (but not simple

cost studies), reporting both costs and outcomes — sometimes referred to as efficiency

studies — which also rank near the top of evidence hierarchies.

Findings

Radiofrequency ablation was initially indicated as a treatment option for inoperable hepatic tumors. The

liver is a common site for metastasis from solid tumors, and many are unsuitable for surgical excision

because of their number, distribution, or the presence of extrahepatic spread (NCCN, 2017a).

Increasingly, radiofrequency ablation is becoming an attractive treatment option for locoregional

control, palliation, and, in some circumstances, cure of other solid tumors, including some operable

tumors for which well-established local or systemic treatment alternatives are available. For patients

Page 5: Radiofrequency ablation of tumors...liver is a common site for metastasis from solid tumors, and many are unsuitable for surgical excision because of their number, distribution, or

5

who present with significant surgical risks or who have significant competing comorbidities,

radiofrequency ablation balances potential cure, locoregional control, or palliation with treatment

toxicity and benefits common to any minimally invasive procedure (e.g., preserving normal organ tissue,

decreasing morbidity, decreasing length of hospitalization).

Existing evidence and clinical experience supports radiofrequency ablation as a safe procedure in the

hands of an experience specialist and effective in tumor destruction, which may be associated with

higher survival rates for some cancers. The most common complications include post-procedural pain,

fever, and burns. An absolute contraindication is uncontrolled coagulopathy. Other relative

contraindications primarily relate to tumor location and underlying organ function.

To be amenable to ablation, typically a 1 cm margin of tumor-free tissue is needed, except in cases of

palliation or debulking, and the tumor must be in an accessible location and away from major organs

and vessels. Currently, there is no standard tumor size or number of tumors appropriate for ablation;

however, studies have found improved outcomes when tumors 4 cm or smaller are treated (NCCN,

2017a, b, c; Interqual, 2016). Typically, choice of ablative technique is based on tumor size

(radiofrequency ablation is most effective for treating tumors < 3 cm at their longest axis) and location

and underlying organ function (NCCN, 2017a). Except for studies of osteoid osteoma, most studies

included patients older than 17 years.

Radiofrequency ablation is an established treatment alternative for the following hepatic indications

(NCCN, 2017a, b, c; ACR, 2015):

Early-stage hepatocellular carcinoma:

- Curative therapy for isolated tumors ≤ 3 cm (in select cases, up to 5 cm).

- Locoregional therapy in medically inoperable patients.

Neoadjuvant therapy as a bridge to transplant.

Isolated colorectal liver metastasis < 3 cm to 5 cm.

There is sufficient evidence to support radiofrequency ablation as a locoregional treatment option for

the following extrahepatic indications:

Early-stage renal cell carcinoma without metastasis (NCCN, 2018a).

Symptomatic osteolytic bone metastases in persons who have failed, or are poor candidates

for, standard treatments such as radiation or opioids (Rosian, 2017; Rosenthal, 2012;

Warmuth, 2012).

Osteoid osteomas that cannot be managed successfully with medical treatment (Rosenthal,

2012; Warmuth, 2012).

Primary or secondary lung cancers (NCCN, 2018b; NICE, 2010a):

- Early-stage, resectable (stage I-II, N0) non-small cell lung cancer in patients who are

medically inoperable or refuse surgery (Bi, 2016; Sher, 2011).

- For patients who are not candidates for stereotactic ablative radiotherapy, external

beam radiation therapy, or sublobar resection; who have failed stereotactic ablative

radiotherapy; or for whom local control may not be the highest priority (NCCN,

2018b).

Primary therapy for intestinal metaplasia (Barrett’s esophagus) (NCCN, 2017d; Almeida,

2016; NICE, 2014; NICE, 2010b).

Residual or recurrent high-grade or low-grade esophageal dysplasia after esophageal

resection (NCCN, 2017d; Evans, 2013).

Thyroid cancer for locoregional control when standard therapy (e.g., surgery or local

therapies) is contraindicated, has failed, or is refused (NCCN, 2017e).

Metastatic (synchronous stage IV) soft tissue sarcoma of the trunk, extremity, head, or neck

(NCCN, 2018c):

Primary local therapy when confined to a single organ and limited tumor bulk.

Palliative therapy for symptomatic disseminated disease.

There is insufficient evidence to support the use of radiofrequency ablation for treatment of any other

malignant primary tumor or benign tumor, such as Morton’s neuroma (American Orthopaedic Foot and

Ankle Society, 2018; Valerio, 2017; Peek, 2016; Association of Extremity Nerve Surgeons, 2014; Fegrachi,

Radiofrequency ablation

for treatment of Barrett’s

esophagus

Key points:

Systematic review and cost analysis of two randomized controlled trials (RCTs), eight

single‐arm cohort studies, and one systematic review for high-grade dysplasia, and two

RCTs, one single-arm cohort study, and two meta-analyses for low-grade dysplasia.

Considered standard of care for treatment of high-grade dysplasia based on good-quality

evidence of effectiveness and safety in eliminating dysplastic tissue and higher morbidity

associated with esophagectomy.

More controversial for low-grade dysplasia based on lower quality evidence of diagnostic

accuracy, uncertainty surrounding the progression rates to cancer, and the spontaneous

reversion in some patients. Routine use not recommended but may be considered in

patients with risk factors suggestive of higher risk of progression to high-grade

dysplasia/cancer (e.g., multifocal, long segment, or persistent Barrett’s esophagus).

with stereotactic body

radiation therapy in

inoperable stage I non-

small cell lung cancer

Key points:

Systematic review and pooled analysis of 31 primarily case series of stereotactic body

radiation therapy (2,767 patients) and 13 studies of radiofrequency ablation (328

patients).

Local tumor control rates (95% confidence interval) at 1, 2, 3, and 5 years:

- Radiofrequency ablation = 77% (70% to 85%), 48% (37% to 58%), 55% (47% to

62%), and 42% (30% to 54%), respectively.

- Stereotactic body radiation therapy = 97% (96% to 98%), 92% (91% to 94%),

88% (86% to 90%), and 86% (85% to 88%) (P < .001).

Differences remained significant after correcting for stage IA and age (P < .001 at 1 year,

2 years, and 3 years; P = .04 at 5 years).

No statistically significant difference in overall survival between modalities (P > .05).

Most frequent complication of radiofrequency ablation was pneumothorax (31%) and of

stereotactic body radiation therapy was (grade ≥ 3) radiation pneumonitis (2%)

Radiofrequency ablation significantly decreased nodule volume at 1, 3, 6, 12, and the last

follow-up months compared to baseline, including a decline by cold and hot nodules.

Radiofrequency ablation decreased the largest diameter, symptom score, cosmetic score,

triiodothyronine level, and vascular scale, had no effect in free thyroxine, and increased

thyrotropin level.

laser-, or microwave-ablation.

Page 8: Radiofrequency ablation of tumors...liver is a common site for metastasis from solid tumors, and many are unsuitable for surgical excision because of their number, distribution, or

8

Citation Content, Methods, Recommendations

Highest rate of complete ablation was achieved with radiofrequency ablation (87.1%,

491/564 patients) and microwave ablation (83.2%, 89/107 patients).

Microwave ablation had the highest rate of short-term complications (14.6%, 21/144

patients).

Overall recurrence rate = 4.2% (24/570 patients) and most often with laser ablation

(10.7%, 11/103 patients).

Radiofrequency ablation had the shortest treatment times (15.6 ± 5.6 min) and high-

intensity focused ultrasound the longest (101.5 ± 46.6 min).

Adequately powered and prospectively conducted cohort trials are needed to confirm

complete pathological ablation in all patients.

Fegrachi (2014)

Radiofrequency ablation

for unresectable locally

advanced pancreatic

cancer

Key points:

Systematic review of five non-comparative studies (158 total patients).

Overall quality: low with high risk of bias and heterogeneous study populations and

outcomes.

Median survival after radiofrequency ablation = three months to 33 months.

Procedure-related morbidity = 4% to 37%, overall mortality = 0% to 19%, overall morbidity

= 10% to 43%. Pooling of data was not done due to heterogeneous study populations and

outcomes.

Radiofrequency ablation appears safe when used with the correct temperature and at an

appropriate distance from vital structures, but multi-center RCTs are needed to determine

the true effect size of radiofrequency ablation and to minimize bias.

Key points:

Systematic review of three case series of benign thyroid nodules, one case series of

thyroid cancer, and two case series of adrenal tumors.

Overall quality: very low.

Thyroid tumors: radiofrequency ablation is safe and improves tumor-related symptoms.

Adrenal tumors: radiofrequency ablation is safe and possibly improves aldosteronism and

reduces recurrence.

Higher-quality studies are needed to confirm these findings.

approximately 44 days; drop-out rate = 38%.

Marginal improvement in quality of life, median survival was four months, 45% with

serious complications, and 5% procedure-related mortality.

the art in interventional

oncology: benign and

involving bone

Key points:

Percutaneous radiofrequency ablation is an important treatment for both benign bone

tumors and palliation of metastases involving bone and soft-tissue sites beyond the liver

and lung.

Image-guided radiofrequency ablation is now the standard treatment for osteoid osteoma,

as the procedure can be performed with higher rates of technical success, decreased

morbidity, and lower cost than those with open surgery.

Citation Content, Methods, Recommendations

Several ablation methods can effectively treat focal metastatic skeletal disease, primarily

with the goal of durable palliation of pain, particularly when conventional therapies,

including chemotherapy and external-beam radiation, have failed.

Warmuth (2012) for the

LBIHTA

Radiofrequency ablation of

bone tumors (osteoid-

osteoma and osseus

metastases)

Key points:

Systematic review of four prospective case series (175 total patients aged 15 years to 23

years) of radiofrequency ablation for osteoid osteomas with a maximum tumor size = 15

mm, and two prospective case series (79 total patients aged 58 years to 62 years) with

osseous metastases with a mean tumor size of 5 cm.

Osteoid osteomas: residual and recurrent symptoms (pain) in 5% to 26% and 0% to 8% of

patients, respectively. Procedure-associated morbidity varied from 0% to 26%.

Painful osseous metastases: statistically significant reduced pain and improved mood at

one and three months following radiofrequency ablation. The local recurrence rate was

42% after 6 months. Intervention-associated pain was observed in 11% to 75% of

patients, other adverse events were seen in 2% to 13% of patients.

Sher (2011)

Cost-effectiveness

analysis of stereotactic

body radiation therapy and

radiofrequency ablation for

medically inoperable,

early-stage non-small cell

lung cancer

Key points:

Markov model describes health states of 65-year-old men with medically inoperable non-

small cell lung cancer after treatment with three-dimensional conformal radiation therapy,

stereotactic body radiation therapy, and radiofrequency ablation. Patients were assumed

to receive supportive care after recurrence. Utility values, recurrence risks, and costs

were adapted from the literature, and sensitivity analyses performed.

Stereotactic body radiation therapy was the most cost-effective treatment over a wide

range of treatment and disease assumptions. On the basis of efficacy and cost,

stereotactic body radiation therapy should be the primary treatment approach for this

disease.
