Long-term results of intrathoracic chemohyperthermia (ITCH) for the treatment of pleural malignancies.

ABSTRACT: There is no standard treatment for patients with pleural malignancies. The aim of this prospective study was to investigate the toxicity and long-term results of a multimodality treatment consisting of surgery and intrathoracic chemohyperthermia (ITCH) for the treatment of patients with pleural malignancies. From January 1990 to August 2000, 24 patients with mesothelioma (n=17), fibrosarcoma (n=3), pleural adenocarcinoma (n=3) and thymoma (n=1) were included. The mesothelioma stages were T1 or T2 in 10 cases, and T3 or T4 in seven cases. After cytoreductive surgery, ITCH was carried out for over 60 min, at inflow temperatures less than 45 degrees C, either with mitomycin C (n=7) or cisplatin (n=5) or both (n=12). One patient died from major thoracic air leaks after major decortication and pleurectomy. Seven patients had complications, one pleural clotting necessitating reoperation. After a median follow-up of 89 months, the overall 1-year and 5-year survival rates were 74 and 27%, respectively. For T1 and T2 mesothelioma patients, the median survival was 41.3 months, and for T3 and T4 tumours, it was 4.5 months (P=0.001). The fibrosarcoma patients are alive with no evidence of recurrence at 24, 43 and 54 months. In the conclusion, the combination of surgery with ITCH with mitomycin and/or cisplatin is relatively safe. This procedure may offer unexpected long-term survival in a selected group of patients (T1 and T2 mesothelioma patients and fibrosarcoma patients).

Project description:Melanoma treatment has been revolutionized over the past decade. Long-term results with immuno-oncology (I-O) agents and targeted therapies are providing evidence of durable survival for a substantial number of patients. These results have prompted consideration of how best to define long-term benefit and cure. Now more than ever, oncologists should be aware of the long-term outcomes demonstrated with these newer agents and their relevance to treatment decision-making. As the first tumor type for which I-O agents were approved, melanoma has served as a model for other diseases. Accordingly, discussions regarding the value and impact of long-term survival data in patients with melanoma may be relevant in the future to other tumor types. Current findings indicate that, depending on the treatment, over 50% of patients with melanoma may gain durable survival benefit. The best survival outcomes are generally observed in patients with favorable prognostic factors, particularly normal baseline lactate dehydrogenase and/or a low volume of disease. Survival curves from melanoma clinical studies show a plateau at 3 to 4 years, suggesting that patients who are alive at the 3-year landmark (especially in cases in which treatment had been stopped) will likely experience prolonged cancer remission. Quality-of-life and mixture-cure modeling data, as well as metrics such as treatment-free survival, are helping to define the value of this long-term survival. In this review, we describe the current treatment landscape for melanoma and discuss the long-term survival data with immunotherapies and targeted therapies, discussing how to best evaluate the value of long-term survival. We propose that some patients might be considered functionally cured if they have responded to treatment and remained treatment-free for at least 2 years without disease progression. Finally, we consider that, while there have been major advances in the treatment of melanoma in the past decade, there remains a need to improve outcomes for the patients with melanoma who do not experience durable survival.
