RESUMEN

Pleural mesothelioma (PM) is a rare but aggressive thoracic tumor with a poor prognosis. Multimodal treatment-including induction chemotherapy, aggressive surgical resection, radiotherapy and immunotherapy in selected cases-currently represents the best therapeutic option. Single-center studies advocate hyperthermic intrathoracic chemotherapy (HITHOC) during surgical resection as an additional therapeutic option, although its impact on post-operative morbidity and survival has not yet been evaluated on a larger scale. HITHOC can be applied not only in the case of mesothelioma, but also in the case of thymoma with pleural involvement or-in very selected cases-in patients with secondary pleural metastases. Despite favorable outcomes and reduced clinical risks, there is no uniform approach to HITHOC, and a wide variety of indications and technical applications are still reported. Based on available data, HITHOC seems to offer a clear benefit in regard to overall survival of all mesothelioma patients; however, multicenter randomized controlled trials are required to validate and standardize this approach. The aim of this review is to focus on the present role of HITHOC in thoracic tumors with pleural involvement as well as on future challenges, particularly in the light of possible combined therapy of thoracic tumors still presenting poor prognoses.

RESUMEN

Background: Cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy (S-HITHOC) may be effective in treating thymic epithelial tumors (TETs) with pleural spread or recurrence. This study will evaluate the safety and efficacy of S-HITHOC in the treatment of TETs with pleural spread or recurrence. Methods: This study is an open, single-arm, prospective trial. Approximately 37 patients diagnosed with TETs with pleural spread or recurrence at the Zhongshan Hospital of Fudan University will be recruited and treated with S-HITHOC. The co-primary outcomes of the study are the length of postoperative hospital stay, complications, and overall quality of life (QoL). The secondary outcomes include drainage duration, volume, and cumulative pain scores. Discussion: This trial was approved by the Zhongshan Hospital Research Ethics Committee. The study findings will be actively disseminated through manuscript publications and conference presentations. Information sheets will be provided to each participant, and informed written consent will be obtained for each evaluation. This prospective study will evaluate the effectiveness of a surgical resection combined with the HITHOC procedure in treating TETs with pleural spread or recurrence in China and will support the standardization of the procedure. Registration: This trial was registered on Clinialtrial.gov (No. NCT05446935).

RESUMEN

OBJECTIVE: To compare the efficacy and safety of hyperthermic intrathoracic/intraperitoneal chemotherapy versus conventional intrapleural/intraperitoneal chemotherapy in the treatment of malignant pleural or peritoneal effusion. METHODS: A randomized clinical trial was carried out in 8 cancer centers across China. Patients with malignant pleural or peritoneal effusion were randomly assigned to the study group or control group. Patients in the study group were treated with cisplatin-based hyperthermic intrathoracic chemotherapy (HITHOC) or hyperthermic intraperitoneal chemotherapy (HIPEC), while the control group was treated with conventional intrapleural or intraperitoneal chemotherapy using same chemotherapeutic regime as the study group. The objective response rate (ORR) was analyzed as primary outcome. Quality-of-life (QOL) score was recorded as secondary outcome using the questionnaire 30 (QLQ-C30) of the European Organization for Research and Treatment of Cancer (EORTC). The efficacy and safety of the two treatments were compared. RESULTS: Total 135 patients were recruited and randomized in this study, with 67 patients in the study group and 68 patients in the control group. The ORR in the study group (80.70%) was significantly higher than that in the control group (31.03%, p < 0.001). However, neither changes of QOL scores, nor incidence rates of adverse events were significantly different between the two groups (p = 0.076 and 0.197, respectively). CONCLUSION: Efficacy of HITHOC or HIPEC is superior to that of conventional modality for the treatment of malignant effusion with comparable side effects.

RESUMEN

Hyperthermic intrathoracic chemotherapy (HITHOC) adjunct to surgery for Malignant Pleural Mesothelioma (MPM) has no definite role. The primary objective of this pilot-trial was to evaluate the feasibility for future large studies. The study design was a prospective randomized three-centric pilot trial. We recruited patients diagnosed with MPM and prospectively assigned them to two groups: Group A: Video Assisted Thoracic Surgery (VATS) talc pleurodesis or Group B: Video-assisted P/D plus HITHOC. From November-2011 to July-2017 24 males and 3 females, with a median age of 68-years were enrolled (recruitment rate 5 patients/year). Preoperative stage was I-II, and 18 had epithelioid type. 14 patients were in the Group A. Operative mortality was 0. Follow-up ranged 6-80 months. The median overall survival time started to diverge at 20 months, being 19 months (95% CI 12-25) in Group A and 28 months (95% CI 0-56) in Group B. Survival rate for the epithelioid type was 15 months (95% CI 0-34) in Group A and 45 months (95% CI 0-107) in the Group B. These findings suggest that video-assisted P/D plus HITHOC may improve survival time in MPM patients undergoing surgical treatment and support the need for a larger multicenter randomized clinical trial.

RESUMEN

Although the method of hyperthermic intrathoracic chemotherapy (HITHOC) after cytoreductive surgery is known for more than 20 years now, the interest of the scientific community has been growing especially in recent years with annually increasing numbers of publications. The feasibility and safety of HITHOC has already been demonstrated. The primary objective now is to reach a consent about the optimal implementation and standardization of the procedure. In the international clinical practice of HITHOC the parameters of temperature, duration, type and number of chemotherapeutic agents vary, making a comparison of the short- and long-term results difficult. For about ten years, the combination of surgical cytoreduction and HITHOC has been performed more routinely in several departments of thoracic surgery in Germany, especially in university hospitals. Recently, a group of experts for thoracic surgery of five departments of thoracic surgery elaborated recommendations for the HITHOC procedure in Germany. These recommendations represent a standardized and consistent implementation of HITHOC. Through this, postoperative complications associated to HITHOC should be reduced and a better comparison of the results should be enabled. This article is intended to give a brief overview of the literature, current recommendations in the implementation of HITHOC and also aims to show future perspectives of this procedure.

RESUMEN

The traditional treatment of stage IV lung cancer is predominantly supportive or palliative. No current standardized guidelines promote the use of hyperthermic intrathoracic chemotherapy (HITHOC) in the treatment of advanced lung cancer with pleural involvement. Several small studies have examined the safety and utilization of HITHOC for this population, though the data is extremely limited. A review of the literature is presented in accordance with the Narrative Review checklist. The MEDLINE electronic database was searched for articles published in English from January 1999 - August 2020 using relevant keywords such as "hyperthermic intrathoracic chemotherapy", "hyperthermic intrapleural chemotherapy" and "HITHOC". This was supplemented by review and hand search of the reference lists. While data suggest a potential though controversial role for HITHOC for certain intrathoracic tumors such as malignant pleural mesothelioma and thymoma, there is insufficient evidence to confidently promote a role for hyperthermic intrathoracic chemotherapy in the treatment of advanced lung cancers. Existing studies are small, nonrandomized, and prone to bias. Hyperthermic intrathoracic chemotherapy is not a standardized treatment for advanced lung cancer, and is characterized by potentially serious side effects with little clinical benefit. Recent developments in targeted therapy and immunotherapy are unlikely to leave room for the development of large randomized controlled trials.

RESUMEN

Non-small cell lung cancer (NSCLC) with ipsilateral pleural dissemination (pM1a) is generally contraindicated for surgery owing to the extremely poor survival. However, some studies have demonstrated that primary tumor resection (PTR) may prolong the survival of these patients. Besides, with the development of systemic therapy, it is still hard to decide the best therapy model for pM1a patients. Thus, we reviewed essential studies about NSCLC with pleural disease and summarized the progress of new techniques in recent years, trying to provide promising new horizons about the management of pM1a patients. Firstly, we suggest performing PTR for highly selected pM1a patients, combined with appropriate systemic therapies and follow-up strategies. Secondly, hyperthermic intrathoracic chemotherapy (HITHOC) can control the symptoms and prolong the survival of NSCLC patients with malignant pleural effusion (MPE). It could also combine with PTR together. Finally, application of genetic testing and circulating tumor DNA (ctDNA) monitoring may furthermore make it possible for personalized management of pM1a patients in the future.
