thoracic oncology – Thoracic Surgery

Memphis, Tennessee USA

Recently, I had the great pleasure and privilege to have a sit down interview with one of the thoracic surgeons whose work I have long admired. Loyal readers will certainly recognize the name, Dr. Benny Weksler, one of the modern masters of esophageal surgery.

Minimally invasive esophagectomies (MIE)

He is best known for his minimally invasive esophagectomies which take much of the pain (literally) out of the traditional surgical resection for esophageal cancer. The minimally invasive esophagectomy is the VATS approach to esophagectomy, using smaller 2 to 3cm ‘ports’ instead of large incisions.

In classic thoracic surgery, large open incisions such as the Ivor Lewis esophagectomy were the best way to optimize survival for patients with this aggressive cancer. However, the traditional open surgery itself is particularly arduous and has been likened to the “open heart surgery” of the thoracic specialty. The Ivor Lewis in particular is two full-sized surgeries; a full thoracotomy combined with a transverse laparotomy. While it has been utilized for decades for excellent visualization, staging and resection, the recovery is a long, painful process.

Dr. Weksler in the mid-south

It’s been just over three years since Dr. Benny Weksler was recruited to start a new thoracic surgery program at The University of Tennessee – West Cancer Clinic – Methodist Hospital System here in Memphis, Tennessee. It’s been a big change, and a bit of an eye-opening experience for the Brazilian native and famed thoracic surgeon who has spent much of this career in the northeast. Prior to this, he was part of the renowned University of Pittsburgh Medical Center under the famed Dr. James Luketich. Since Dr. Weksler’s move, he’s still adjusting to the warmer weather here, which is one of the things he likes best about the area along with the traditional Memphis music scene, which the city is famous for.

It’s also been a time of great changes and innovations for Memphis and the University of Tennessee, as well. Dr. Weksler started the first thoracic surgery service line for the UT – Methodist Hospital system, which is actually the first real dedicated thoracic surgery service line in the Memphis area – which extends across a tri-state area that also covers parts of northern Mississippi and western Arkansas.

Why is this important and what does it mean for Memphis?

Prior to Dr. Weksler’s arrival, patients were either referred to private cardiothoracic surgery practices in Memphis, they went to larger cities with bigger academic centers or they unwittingly trusted their health to a non-specialty surgeon. Neither of those options were ideal, but now patients in the northern Mississippi delta – metro Memphis area can receive state-of-the-art, surgical excellence close to home. For some patients, this is a matter of life or death.

Now the program is growing; so much so, that Dr. Weksler has two full-time thoracic surgeons and is actively looking for a third. With the addition of the third surgeon, Dr. Weksler hopes to expand the UT program to serve local veterans at the Memphis VA.

While Dr. Weksler doesn’t embrace the principles of uniportal surgery, his work on esophagectomies more than makes up for it. In fact, Dr. Weksler is one of the leading surgeons in the United States for minimally invasive esophagectomies. As discussed in previous posts, an experienced esophageal surgeon is critical for patient survival. (Bare Minimum competency for any esophageal surgeon is 25 cases a year – it’s not a surgery for your ‘average’ thoracic surgeon or any general surgeon).

Memphis’ newest secret weapon against cancer (too bad no one knows that he’s here)

In fact, his presence here in Memphis, among otherwise limited surgical services, is like finding a diamond while scavenging for supper in a metal dumpster in a hundred degree heat. In addition to being one of the foremost surgeons for esophageal disease (cancer and benign esophageal disease like achalasia), Dr. Weksler is also an experienced robotic surgeon.

As a newcomer to town, Dr. Weksler is having to re-build his practice volumes. As he explains, “We do about 30 esophagectomies a year, and I also see approximately 60 patients with esophageal cancer that cannot be operated on. 100% of our esophagectomies since I have been here were done minimally invasive”.

I can only speculate as a knowledgeable outsider that these surgical volumes reflect the lack of the general public and referring physicians knowledge about Dr. Weksler’s presence in the mid-south. Dr. Weksler is the type of surgeon that patients will travel across the country to see. My guess is that many of these potential patients are still traveling to Pittsburgh.

New ideas, new programs and new service lines

Dr. Weksler brings with him new ideas and new programs aimed at treating all Memphians. This includes community programs aimed at underserved and at-risk communities. One of these programs focuses on the diagnosis and treatment of lung cancer in African -American communities, which are disproportionately affected by advanced lung cancer, particularly in middle-aged males. By creating and implementing screening programs in these communities, Dr Weksler and his team are able to diagnose and treat lung cancers at earlier stages and improve patient survival. Despite being in its infancy, the program (which does not have a formal name) has screened over 100 patients and diagnosed eight cancers.

Changing the art of Medicine & Surgery in Memphis

Dr. Weksler has been instrumental in creating at atmosphere of multidisciplinary collaboration. For example, programs have been streamlined and designed with patients in mind, to be the most effective, informative and efficient. This means that patients receive a “one stop shopping” experience as Dr. Weksler describes it. Patients are able to see their medical oncologist, thoracic surgeon and radiation oncologist on the same visit. All patients and their cases are presented at tumor board, to determine that treatment is individualized to the patient’s condition, functional status and tumor type which adhering to the clinical guidelines and evidence-based practice to optimize patient outcomes and long-term survival.

Q & A with Dr. Weksler – What patients should expect

Dr. Weksler talked to me at length about this multidisciplinary team approach as well as what patients should expect when they come to Methodist/ West Cancer center for care.

Question: What is the general process/ timeline for patient who has been referred to your clinic for evaluation?

Dr. Weksler: When patients come into the multidisciplinary clinic, patients / families with esophageal cancer will leave the office with a pretty good idea of what is going to happen. Depending on the work up done before they see me [which includes identification of tumor/ cancer staging], we will do the radiation therapy simulation the following
week, and start chemotherapy and/or radiation therapy the next week.

Question: What diagnostics/ medical records should they bring with them?

Dr. Weksler: We would like to see all available records, including previous surgeries, all scans, PET/ CT scans, barium esophagram, endoscopy report and all biopsy reports.

Question: What should patients anticipate? (will they get feeding tubes prior to surgery, etc)?

Dr Weksler: Most patients will get a port for chemotherapy*. We place feeding tubes in patients that loss more than 10% of their weight, or if they suffer from severe dysphagia. Patients can expect a 5 week course of chemotherapy and/or radiation therapy, followed by an interval of 6 to 8 weeks, followed by surgery.

*Editor’s note: A port is a long-term but temporary and completely removable central intravenous access for chemotherapy administration. It is placed underneath the skin with no cords, or lines visible externally. Feeding tubes are also temporary tubes that are easily removed/ reversible but help the patient to maintain adequate nutrition necessary for healing.

Report from the 3^rd Mediterranean Symposium in Thoracic Surgical Oncology on VATS RESECTIONS FOR LUNG CANCER: moving toward standard of care.

Speakers and moderators at the 3rd Mediterranean Symposium on Thoracic Surgical Oncology

The third mediterranean symposium on thoracic surgical oncology was successful. The symposium was held the 21^st – 22^nd april 2016 at the Aula Magna of the Faculty of Medicine at the University of Catania. More than 150 people attended, and among them there were thoracic surgeons, general surgeons, oncologists, chest physicians, residents and medical students. This year, we had speakers from Europe and the USA. The main topic was VATS resections for lung cancer (Photo 1). During the opening ceremony, the Rector Giacomo Pignataro awarded a medal to Professor Tom Treasure for enhancing our outstanding education and research experience (Photo 2).

Although the concept of operating thru a small port was born and developed in Europe (1- 7) it has been noted that 90% of papers on uniportal VATS lobectomy come from East Asian countries (8-11). Throughout the symposium different speakers agreed that a proper definition of uniportal VATS is mandatory to speak the same language worldwide.

Awake thoracic surgery was discussed together with the need of accurate preoperative staging procedures such as endobronchial ultrasound, videomediastinoscopy or Video-assisted mediastinal lympadenectomy. It was concluded that a wide spectrum of factors must be considered when determining the appropriate tests to assess the lymph nodes in NSCLC, which includes not only the sensitivity and specificity of the test, but also the ability to perform the procedure on an individual patient.

Data from New York showed very clearly that there have been no large-scale randomized control trials to compare open and VATS lobectomy. Although most may agree with the short-term superiority of VATs lobectomy over its open counterpart, many argue that is an in adequate oncologic procedure. Hence whether the approach is equivalent in overall and cancer specific survival to its open counterpart is not known. He also reported an important recent analysis of SEER-Medicare which confirmed that VATS lobectomy appears to have similar survival to its open counterparts (12).

A magnificent video was presented to explain every step of the lobectomies performed through a small skin incision. A long discussion followed and all auditorium proposed that ‘single incision’ VATS probably define better than uniportal VATS what surgeons are doing worldwide. Certainly the length of skin incision is important and should be taken in serious consideration. We felt that a consensus conference is probably necessary consensus conference is probably necessary. The indication for a Wedge resection rather than lobectomy in initial stage lung cancer is still weak.

The Italian VATS group was formed in 2013 , and nowadays there are 65 participating centres and that 2800 VATS lobectomy have already been included. In Catania we joined the group few months ago (13)

A very interesting session for juniors and medical students from UK and Italy was carried out, and 12 abstracts have been presented as interactive posters. Two of them have been chosen for possible publication in Future Oncology.

Finally, the first data survival seems to benefit little from the various even growing “personal” modifications of the standard VATS technique. Since there is a limited variation between VATS and uniportal VATS, the likelihood is that either VATS and uniportal VATS will be operative in the near future. Its success will depend on survival advantages and decrease chest pain and not just on new technical instrumentation. To protect patient’s safety, the length of the skin incision should be chosen on the basis of several clinical factors and not in relation of modern “demand”. Although the trial VIOLET is ongoing in UK to demonstrate if VATS resection for lung cancer is better than open thoracotomy, doubts arises as standard postero-lateral thoracotomy for lung cancer seems to be an incision which is performed rarely today. A skin incision of 6-8 cm (mini-thoracotomy) with video assistance is enough for most of lung resections. The question which arises is if a mini-thoracotomy of 6 cm should be called “uniportal” or not.
