Cytoreductive surgery and HITHOC

Q and A with Migliore et al.. about Hithoc and Mesothelioma in Catania, Italy

Dr. Migliore and his team performing HITHOC

As discussed in a previous post on HITHOC and Mesothelioma, Dr. Marcello Migliore and his colleagues in Catania, Italy have published results from a small pilot study on the use of HITHOC (cytoreductive surgery and intrathoracic chemotherapy) to treat malignant pleural mesothelioma.

Thoracics.org contacted Dr. Migliore to find out more about that study as well as his on-going research in this area. He was also kind enough to offer his opinions on Hope and the diagnosis of malignant mesothelioma.

On-going research on HITHOC

Thoracics.org: Dr. Migliore, woud you tell us more about your current research on HITHOC and mesothelioma?

Dr. Migliore: We are conduction a pilot study to compare pleurodesis with talc vs HITHOC in mesothelioma patients. Goals are quality of life and survival.

Thoracics.org: How many more patients are you hoping to enroll ?


Dr. Migliore: we hope to enroll at least 12 patients (unfortunately in almost 2 years we enrolled only 6 patients)

Thoracics.org:  Would you tell us more about eligibility criteria?

Dr. Migliore:  All patients with mesothelioma will enter the study protocol except those who cannot undergo surgery for poor performance status.

Thoracics.org:  Would you describe the procedures for our readers?

Dr. Migliore: Talc pleurodesis is performed using the uniportal VATS technique (2 cm skin incision), which is a concept that was introduced  by us already in 1998 (and published in 2001 and 2003).  As you know,  Gonzalez- Rivas  is now well known worldwide for using  the concept of uniportal technique to perform major lung resection. Pleuerectomy and decortication with HITHOC is  performed using the bi-portal VATS technique but with an skin incision of around 8 cm.

Thoracics.org:  In your preliminary paper on your last pilot study, there were a couple patients with lung cancer who were included in the HITHOC trials.  Is that the same for your current study?

Dr. Migliore:  While I feel that some patients with lung cancer could have benefited from HITHOC, for this study, the indications must be strictly limited [to patients with malignant mesothelioma only].

As you know, the largest group of patients with lung cancer are patients with more advanced cancer; stage IV lung cancer patients, and because survival  is dismal, the standard practice is no surgery except palliative procedures. But, there are selected patients in whom there is some evidence that surgery could help. For this reason my personal reaction is that,  in the near future, we should aim to prolong survival in stage IV lung cancer patients also by surgery. We are in mind to start a new study on the role of surgery in selected stage IV lung cancer patients.

Technical Aspects on HITHOC

Thoracics.org: Does previous pleurodesis make surgery more difficult?

Dr. Migliore: Yes, due to the development of adhesions between parietal pleura and  the chest wall, as well as between the parietal and the visceral pleura, which are really difficult to remove.  It requires delicate work using the fingers ( at the end of the operation you can have pain in fingers and fingertips!)

Thoracics.org: Does it lead to increased operating room time, or increased bleeding from adhesions?

Dr. Migliore:  While is certainly increases operating time but there is no evidence of increased bleeding but air leaks are more frequent. Intraoperatively, it is imperative to put attention to every single detail to avoid postoperative complications.

Thoracics.org: Do you find that patients with diaphragm involvement develop more post-operative complications or are more likely to develop disseminated disease ?

Dr. Migliore: That has not occurred in this group of patients but the number of patients is small, and therefore it is impossible to answer.

Other considerations

Thoracics.org: What has been the biggest obstacle in your research?

Dr. Migliore: Certainly living in a “rural” region with cultural dogmas and financial restriction for research are probably the most common obstacles to speedy clinical surgical research.

On Hope & Malignant Mesothelioma

[During a related study] “We operated two patients and one is alive after 3 years. She was 40 y.o. lady with a 15 year-old child. She had malignant pleural effusion with a peripheral lung tumor and was treated elsewhere with talc pleurodesis alone, and 6 months survival was given. We performed a parietal and visceral pleurectomy with HITHOC. She is alive (with recurrence) and her son is now 18 yo. This simple case give an explanation that an operation although “experimental, gives hope (we should not give false hope) and permits to these unfortunate patients to see light in the dark”.
