The Role of Hyperthermic Intraperitoneal Chemotherapy in Uterine Cancer Therapy. Int J Mol Sci 2023; 24:12353. [PMID: 37569726 PMCID: PMC10419250 DOI: 10.3390/ijms241512353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 07/28/2023] [Accepted: 07/30/2023] [Indexed: 08/13/2023] Open
Abstract
Endometrial cancer and uterine sarcoma represent the two major types of uterine cancer. In advanced stages, both cancer entities are challenging to treat and correlate with a meagre survival and prognosis. Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a form of localized chemotherapy that is heated to improve the chemotherapeutic effect on peritoneal metastases. The aim of the current review is to study the role of HIPEC in the treatment of uterine cancer. A literature review was conducted using the MEDLINE and LIVIVO databases with a view to identifying relevant studies. By employing the search terms "hyperthermic intraperitoneal chemotherapy", "uterine cancer", "endometrial cancer", and/or "uterine sarcoma", we managed to identify 26 studies published between 2004 and 2023. The present work embodies the most up-to-date, comprehensive review of the literature centering on the particular role of HIPEC as treatment modality for peritoneally metastasized uterine cancer. Patients treated with cytoreductive surgery, alongside HIPEC, seem to profit from not only higher survival but also lower recurrence rates. Factors such as the completeness of cytoreductive surgery, the peritoneal cancer index, the histologic subtype, or the applied chemotherapeutic agent, all influence HIPEC therapy effectiveness. In summary, HIPEC seems to represent a promising treatment alternative for aggressive uterine cancer.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in peritoneal sarcomatosis-A systematic review and meta-analysis. Eur J Surg Oncol 2021; 48:640-648. [PMID: 34716035 DOI: 10.1016/j.ejso.2021.10.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 10/08/2021] [Accepted: 10/12/2021] [Indexed: 10/20/2022] Open
Abstract
Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) play an important role in the treatment of various peritoneal surface malignancies, but its efficacy in peritoneal sarcomatosis (PS) remains unknown. Hence, we performed a systematic review and meta-analysis to investigate outcomes of CRS-HIPEC in PS, in accordance with PRISMA guidelines. 16 studies with a total of 320 patients were included in the meta-analysis. Pooled mean length of hospital stay after CRS-HIPEC was 16.0 days (95% CI: 12.2-19.8) and rate of serious complications was 17.4% (95% CI: 9.8-26.3). The median DFS was 12.0 months (95% CI: 8.0-16.0) and the 5-year DFS was 21.8% (95% CI: 13.2-31.7). Overall pooled median OS was 29.3 months (95% CI: 23.8-34.8), with a 5-year OS of 35.3% (95% CI: 26.3-44.8). Subgroup analysis showed that patients with CC-0 cytoreduction had a higher median OS of 34.6 months (95% CI: 23.2-45.9). Median OS for patients with a primary tumour histology of leiomyosarcoma and liposarcoma was 33.5 months (95% CI: 15.9-51.1) and 39.1 months (95% CI: 20.8-57.5) respectively. The site of recurrence was locoregional in 57.3% (95% CI: 38.9-74.8), distant in 17.3% (95% CI: 3.9-35.6), and both in 17.4% (95% CI: 5.8-32.2). In conclusion, our results suggest that CRS-HIPEC may improve outcomes in a select group of PS patients.

Ray MD, Dhall K. Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in the management of peritoneal surface malignancies - An evidence-based review. Curr Probl Cancer 2021; 45:100737. [PMID: 34116836 DOI: 10.1016/j.currproblcancer.2021.100737] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 02/27/2021] [Accepted: 03/15/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND Traditionally, peritoneal surface malignancies (PSM) were considered terminal diseases because of their advanced nature, therefore, systemic chemotherapy was given with palliative intent only. As a result, very poor survival outcomes were observed. But with the introduction of complete Cytoreductive surgery (CRS) and Hyperthermic intraperitoneal chemotherapy (HIPEC), the scenario has changed dramatically. METHODOLOGY An objective electronic database search was performed in Pubmed, NLM Catalog, Google scholar, Bookshelf, and Pubmed Central published in the time period from 2000 till 2020. All the randomized studies were included. In the absence of randomized studies, both prospective and retrospective studies were included. The outcomes of HIPEC were measured in terms of median survival, disease-free survival, overall survival, complications and drug toxicities. RESULTS CRS and HIPEC are considered the standard of care for PMP and MPM even in the absence of level 1 evidence due to lack of an effective alternative treatment. In colorectal and gastric cancer, several phase-three trials are showing overall survival benefit in selected cases while there is a prophylactic and palliative role of HIPEC in gastric cancer. Three reported phase 3 trials showed positive results in ovarian cancer. In peritoneal sarcomatosis, the role of HIPEC is yet to be proven. CONCLUSION The patient selection is the key to the successful outcomes after HIPEC. HIPEC should be performed by the experienced surgeons in specialized centres with a strong critical care and intensive care support to reduce the morbidity and mortality. Ongoing trials and future directions will prove to be an indispensable arm in the oncological armamentarium.

[PMID: 33748383 PMCID: PMC7970133 DOI: 10.1016/j.gore.2021.100741] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 02/22/2021] [Accepted: 02/26/2021] [Indexed: 01/25/2023] Open
Abstract
Six patients underwent cytoreductive surgery plus HIPEC and EPIC for morcellated uLMS. There were no postoperative deaths and a single patient had class 3 adverse events. Three-year overall survival was 50% and 5-year survival 33%. Patients with small volume uLMS or low-grade disease showed long-term survival.
Uterine leiomyosarcoma (uLMS) is a rare aggressive malignant mesenchymal tumor with high risk of recurrence and poor prognosis regardless of stage. It is often diagnosed postoperatively following myomectomy, hysterectomy or supracervical hysterectomy for presumed benign disease. Primary surgery at the diagnosis of uLMS is considered to affect outcomes. If the tumor was morcellated, the oncologist will encounter special problems that require knowledgeable management of peritoneal metastases. We previously reported that six patients who successfully underwent cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) plus early postoperative intraperitoneal chemotherapy (EPIC) to manage the disease dissemination that must occur following morcellation. This is a study for long-term outcome of these patients. Six patients were treated with an absence of grade IV adverse events and no mortality. The median Peritoneal Cancer Index (PCI) was 18 and complete cytoreduction without peritoneal metastases visualized within the operative field at the completion of the surgical procedure (CC-0) was achieved in all patients. One patient was diagnosed leiomyomatosis peritonealis postoperatively. Among five patients who were confirmed uterine leiomyosarcoma, the 3-year overall survival was 40.0% and 5-year overall survival was 20.0% with the median follow-up of 18 months (range 5–73 months). The patient with PCI 0 at the time of CRS showed no evidence of disease (NED) at 73 months. We believe that prophylactic CRS contributed her favorable outcome. Therapeutic options for patients with uLMS post-morcellation are limited. Currently, CRS and HIPEC plus EPIC followed by adjuvant systemic chemotherapy may be considered an option for treatment. Further studies in a larger number of patients are needed.

Abstract
OBJECTIVE To examine the perioperative and survival outcomes in women with disseminated peritoneal uterine leiomyosarcoma (uLMS) who underwent cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS A comprehensive systematic review of literature was conducted using multiple public search engines, PubMed, Scopus, and the Cochrane Library, in compliance with the PRISMA guidelines. Women with disseminated peritoneal uLMS treated with CRS-HIPEC were analyzed. Perioperative morbidity and mortality rate as well as oncologic outcomes related to CRS-HIPEC were assessed. RESULTS Ten studies met the inclusion criteria from 2004 to 2020, including 8 case series (n=28) and 2 original articles (n=47). Of the 75 patients, 68 (90.7%) were women with uLMS whereas 7 women were non-uLMS. Of these, 64 (85.3%) had recurrent disease, and 39 (52.0%) received chemotherapy or radiotherapy prior to CRS-HIPEC. The perioperative mortality rate was 4.0% (intraoperative 1.3%, and postoperative 2.7%), and postoperative complications (grade ≥3) rate ranged 21.4-22.2%. With regard to HIPEC regimens (n=75), cisplatin was most frequently used (n=55, 73.3%) followed by melphalan (n=17, 22.7%) and others (n=3, 4.0%). Among the two observational studies, the median overall survival after CRS-HIPEC treatment was 29.5-37 months. In one limited comparative effectiveness study (n=13), albeit statistically non-significant CRS-HIPEC was associated with higher progression-free survival versus CRS alone (3-year rates, 71.4% versus 0%, P=0.10). When the HIPEC regimens were compared, melphalan use was associated with decreased uLMS-related mortality compared to a cisplatin-based regimen, but the association was not statistically significant (hazard ratio 0.35, 95% confidence interval 0.04-3.05, P=0.35). CONCLUSION Effectiveness of CRS-HIPEC for disseminated peritoneal uLMS is yet to be determined. As interpretation of the available data on survival is limited due to small sample sizes or the lack of an active comparator, further study is warranted to examine the safety and survival effect of CRS-HIPEC in disseminated peritoneal uLMS.

Abstract
BACKGROUND Women 65 years of age or older with epithelial ovarian cancer (EOC) are thought to have a worse prognosis than younger patients. However, no consensus exists concerning the best treatment for ovarian cancer in this age group. This report presents outcomes for patients treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS A prospective database of EOC patients treated with CRS/HIPEC (1998-2019) was analyzed. Perioperative variables were compared by treatment including upfront CRS/HIPEC, neoadjuvant chemotherapy plus CRS/HIPEC (NACT + CRS/HIPEC), and salvage CRS/HIPEC, and by age at surgery (< 65 and ≥ 65 years). Survival analysis was performed, and outcomes were compared. RESULTS Of the 148 patients identified, 42 received upfront CRS/HIPEC, 48 received NACT + CRS/HIPEC, and 58 received salvage CRS/HIPEC. Each group was subdivided by age groups (< 65 and ≥ 65 years). The median overall survival (OS) after the upfront CRS/HIPEC was 69.2 months for the patients < 65 years of age versus 69.3 months for those ≥ 65 years of age. The OS after NACT + CRS/HIPEC was 26.9 months for the patients < 65 years of age versus 32.9 months for those ≥ 65 years of age, and the OS after salvage CRS/HIPEC was 45.6 months for the patients < 65 years of age versus 23.9 months for those ≥ 65 years of age. The median progression-free survival (PFS) after upfront CRS/HIPEC was 41.3 months for the patients < 65 years of age versus 45.4 months for those ≥ 65 years of age. The PFS after NACT + CRS/HIPEC was 16.2 months for the patients < 65 years of age versus 11.2 months for those ≥ 65 years of age, and the PFS after salvage CRS/HIPEC was 18.7 months for the patients < 65 years of age versus 10 months for those ≥ 65 years of age. The median follow-up period for the entire cohort was 44.6 months [95% confidence interval (CI) 34.7-60.6 months]. CONCLUSION Age and feasibility of complete cytoreduction should be considered when treatment methods are selected for elderly patients. A carefully selected elderly population can benefit significantly from aggressive treatment methods.

Abstract
INTRODUCTION Cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) is an effective treatment option for selected patients with peritoneal metastases (PM), but national utilization patterns are poorly understood. The objectives of this study were to (1) describe population-based trends in national utilization of CRS/IPC; (2) define the most common indications for the procedure; and (3) characterize the types of hospitals performing the procedure. METHODS The National Inpatient Sample (NIS) was used to identify patients from 2006 to 2015 who underwent CRS/IPC, and to calculate national estimates of procedural frequency and oncologic indication. Hospitals performing CRS/IPC were classified based on size and teaching status. RESULTS The estimated annual number of CRS/IPC cases increased significantly from 189 to 1540 (p < 0.001). Overall, appendiceal cancer was the most common indication (25.7%), followed by ovarian cancer (23.3%), colorectal cancer (22.5%), and unspecified PM (15.0%). Remaining cases (13.5%) were performed for other indications. Most cases were performed in large teaching hospitals (65.9%), compared with smaller teaching hospitals (25.1%), large non-teaching hospitals (5.3%), or small non-teaching hospitals (3.2%). Patients were more likely to undergo CRS/IPC without a diagnosis based on level I evidence (appendiceal, ovarian, or colorectal) at large non-academic hospitals (odds ratio 2.00, 95% confidence interval 1.18-3.38, p = 0.010) compared with large academic hospitals. CONCLUSIONS Utilization of CRS/IPC is increasing steadily in the US, is performed at many types of facilities, and often for a variety of indications that are not supported by high-level evidence. Given associated morbidity of CRS/IPC, a national registry dedicated to cases of IPC is necessary to further evaluate use and outcomes.
