Enhanced recovery after surgery (ERAS) in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC): a cross-sectional survey

Two-stage cytoreductive surgery for 'extensive' pseudomyxoma peritonei: A legitimate alternative or salvage strategy?

BACKGROUND AND AIM

Two-stage cytoreductive surgery (CRS) has been proposed as an alternative to one-stage surgery in patients who have 'extensive' pseudomyxoma peritonei (PMP) and/or are unfit for very extensive surgery, to reduce morbidity. We review current evidence on two-stage CRS focusing on patient selection, interval between procedures, extent of surgery, use of HIPEC, perioperative and oncological outcomes.

METHODS

This is a narrative review. A literature search on PubMed and Embase was performed using keywords- 'Two-stage cytoreductive surgery', 'pseudomyxoma peritonei', 'high-volume PMP', 'huge PMP', 'cytoreductive surgery', 'HIPEC', 'staged surgery' and 'extensive pseudomyxoma peritonei'.

RESULTS

Five studies reported outcomes in a total of 114 patients. The indications for two-stage CRS were: in two studies, patients undergoing an incomplete cytoreduction due to undue surgical risk were reevaluated for a second surgery during routine surveillance; severe comorbidities in one; extensive disease with PCI>28 in another and in one, only HIPEC was performed as a second procedure due to intraoperative hemodynamic instability (the two-stage procedure was performed in interest of patient's safety). Major morbidity ranged from 0 to 37.5 % (first-stage) and 25%-38.9 % (second-stage). Short term follow-up demonstrated equivalent short-term oncological outcomes compared to historical data. Long term follow-up and quality-of-life data were not available.

CONCLUSIONS

The published studies showed different interpretations and applications of the two-stage CRS concept. The reported morbidity was similar to that after single-stage CRS for extensive PMP. Though short-term survival outcomes are acceptable, long-term follow-up is needed. Planned two-stage CRS should currently be reserved for highly selected clinical situations.

Use of social media for academic and professional purposes by gynecologic oncologists

OBJECTIVE

To investigate the prevalence and patterns of social media use among gynecologic oncologists for professional and academic purposes.

METHODS

A prospective online survey between November and December 2022 targeted gynecologic oncology practitioners (gynecologic oncologists, surgical oncologists, medical oncologists, radiation/clinical oncologists, and onco-pathologists/pathologists). The survey, distributed via various social media platforms, included 40 questions to capture qualitative and quantitative data on social media use.

RESULTS

Of 131 respondents from 32 countries, 106 (80.9%) were gynecologic oncologists and affiliated with academic institutions (84.7%). Facebook (n=110, 83.9%), Twitter (n= 108, 82.4%), and Instagram (n=100, 76.3%) were the most used platforms. Respondents used social media to stay updated (n=101, 77.1%), network (n=97, 74%), learn about conferences and webinars (n=97, 74%), and engage in academic discussions (n=84, 64.1%). Following the COVID-19 pandemic, 100/129 (77.5%) reported increased social media use. However, only 32 (24.4%) used it to connect with patients, and concerns were raised about privacy and the need for separate professional and personal accounts. A quarter of respondents hesitated to share their opinions on social media due to the fear of controversy, with 26 (20%) experiencing cyberbullying, yet 120/130 (92.3%) believed it enabled junior professionals to express their views. Concerns about differentiating valid content, information reliability, and the professional perception of sourcing knowledge from social media were noted. Gender, age, specialty, and income level influenced patterns of social media use, with variations in preferences for platforms, content engagement, and purposes, highlighting a complex landscape of social media interaction among gynecologic oncologists.

CONCLUSION

While the use of social media among gynecologic oncologists is prevalent, particularly for academic and professional development, challenges such as cyberbullying, privacy concerns, and the need for formal training in social media navigation persist. Tailored training programs and guidelines could enhance social media's effective and ethical use in this field, promoting a safe environment for professional expression and engagement.

Enhanced recovery after surgery (ERAS) implementation in cytoreductive surgery (CRS) and hyperthermic IntraPEritoneal chemotherapy (HIPEC): Insights from Italian peritoneal surface malignancies expert centers

BACKGROUND

Cytoreductive surgery (CRS) combined with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a complex procedure that involves extensive peritoneal and visceral resections followed by intraperitoneal chemotherapy. The Enhanced Recovery After Surgery (ERAS) program aims to achieve faster recovery by maintaining pre-operative organ function and reducing the stress response following surgery. A recent publication introduced dedicated ERAS guidelines for CRS and HIPEC with the aim of extending the benefits to patients with peritoneal surface malignancies.

METHODS

A survey was conducted among 21 Italian centers specializing in peritoneal surface malignancies (PSM) treatment to assess adherence to ERAS guidelines. The survey covered pre/intraoperative and postoperative ERAS items and explored attitudes towards ERAS implementation.

RESULTS

All centers completed the survey, demonstrating expertise in PSM treatment. However, less than 30 % of centers adopted ERAS protocols despite being aware of dedicated guidelines. Preoperative optimization was common, with variations in bowel preparation methods and fasting periods. Intraoperative normothermia control was consistent, but fluid management practices varied. Postoperative practices, including routine abdominal drain placement and NGT management, varied greatly among centers. The majority of respondents expressed an intention to implement ERAS, citing concerns about feasibility and organizational challenges.

CONCLUSIONS

The study concludes that Italian centers specialized in PSM treatment have limited adoption of ERAS protocols for CRS ± HIPEC, despite being aware of guidelines. The variability in practice highlights the need for standardized approaches and further evaluation of ERAS applicability in this complex surgical setting to optimize patient care.

Continuous Wound Irrigation and Intraoperative Methadone Decreases Opioid Use and Shortens Length of Stay After CRS/HIPEC

BACKGROUND

Epidural analgesia is resource and labor intense and may limit postoperative management options and delay discharge. This study compared postoperative outcomes after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) with epidural analgesia versus continuous wound infusion system (CWIS) with/without intraoperative methadone.

METHODS

A single-institution, retrospective chart review was performed including all patients undergoing open CRS/HIPEC from 2018 to 2021. Patient demographics, surgical characteristics, length of stay, and in-hospital analgesic use were reviewed. In-hospital opioid exposure in morphine milligram equivalents (MME) was calculated. Multivariate analysis (MVA) for mean total and daily opioid exposure was conducted.

RESULTS

A total of 157 patients were included. Fifty-three (34%) had epidural analgesia, 96 (61%) had CWIS, and 79 (50%) received methadone. Length of stay was significantly shorter with CWIS + methadone versus epidural (7 vs. 8 days, p < 0.01). MVA showed significantly lower mean total and daily opioid exposure with CWIS+methadone versus epidural (total: 252.8 ± 17.7 MME vs. 486.8 ± 86.6 MME; odds ratio [OR] 0.72, 95% confidence interval [CI] 0.52-0.98, p = 0.04; Daily: 32.8 ± 2.0 MME vs. 51.9 ± 5.7 MME, OR 0.72, 95% CI 0.52-0.99, p ≤ 0.05). The CWIS-only group (n = 17) had a significantly lower median oral opioid exposure versus epidural (135 MME vs. 7.5 MME, p < 0.001) and longer length of stay versus CWIS + methadone (9 vs. 7 days, p = 0.04), There were no CWIS or methadone-associated complications and one epidural abscess.

CONCLUSIONS

CWIS + methadone safely offers better pain control with less in-hospital opioid use, shorter length of stay, and decreased resource utilization compared with epidural analgesia in patients undergoing CRS-HIPEC.

Parenteral nutrition after cytoreductive surgery for peritoneal malignancy: Should it be administered routinely?

PURPOSE/BACKGROUND

Cytoreductive surgery (CRS) is complex abdominal surgery that is used to treat peritoneal malignancy. CRS is associated with major morbidity and efforts to address this include optimisation of perioperative care. There is variation in international protocols on the nutritional management after CRS, in particular whether parenteral nutrition (PN) should be routinely or selectively administered.

HYPOTHESIS/AIM

This study assessed parenteral nutrition use, factors associated with PN requirement and nutritional outcomes in a centre that selectively uses PN after CRS.

METHODS/INTERVENTIONS

A retrospective analysis was undertaken on patients who underwent cytoreductive surgery ± hyperthermic intraperitoneal chemotherapy (HIPEC) at Peter MacCallum Cancer Centre between 1st January 2015 and 31st December 2020 using data entered into a prospectively maintained database. Patient characteristics, nutritional status, oncological parameters, operative details and postoperative outcome data were retrieved. Categorical variables were compared using the chi-squared test and continuous data was compared using a non-parametric Mann-Whitney U-test. A p-value <0.05 was considered statistically significant. Cox regression analysis was performed to identify independent predictors of requiring PN and postoperative weight change over admission.

RESULTS

A total of 222 patients who had CRS between were included (mean age 56 years; female 61.3%). Preoperative nutritional characteristics of participants included a mean body mass index (BMI) of 27.6 kg/m2 and the majority (77.9%) were not at nutritional risk pre-operatively with a Patient Generated Subjective Global Assessment (PG-SGA) score of category A. A high proportion of patients had surgery for colonic adenocarcinoma (58.1%), received HIPEC (87.4%) and achieved complete cytoreduction (82%). Postoperative parenteral nutrition was required for 65 patients (29.3%). The most frequent indication for PN was postoperative ileus (63.1%) with the mean (SD) time to commencing PN being postoperative day 5. Factors associated with the requirement for postoperative PN included preoperative albumin (OR 0.89; p = 0.015), weight loss >5% of body weight in the 6 months prior to admission (OR 2.2; p = 0.05), higher PCI score (OR 1.048; p = 0.005), number of anastomoses completed (OR 1.766; p = 0.017) and development of any postoperative complication (OR 2.71; p = 0.009). PN use was not associated with postoperative weight change.

CONCLUSION

Most patients undergoing CRS did not require post-operative PN. Nutritional and operative factors may identify patients who are likely to need PN after surgery. Selective use of PN did not impact on postoperative weight change.

Prehabilitation in the lung cancer pathway: a scoping review

BACKGROUND

Lung cancer is the third most common type of cancer in the UK. Treatment outcomes are poor and UK deaths from lung cancer are higher than any other cancer. Prehabilitation has shown to be an important means of preparing patients both physically and psychologically for cancer treatment. However, little is understood about the context and mechanisms of prehabilitation that can impact physiological and psychological wellbeing. Our aim was to review and summarise primary research on prehabilitation in the lung cancer pathway using a realist approach.

METHODS

A scoping review of empirical primary research was conducted. Five online medical databases from 2016 - February 2023 were searched. All articles reporting on prehabilitation in lung cancer were included in the review. For this review, prehabilitation was defined as either a uni-modal or multi-modal intervention including exercise, nutrition and/or psychosocial support within a home, community or hospital based setting. A realist framework of context, mechanism and outcome was used to assist with the interpretation of findings.

RESULTS

In total, 31 studies were included in the review, of which, three were published study protocols. Over 95% of studies featured an exercise component as part of a prehabilitation programme. Twenty-six of the studies had a surgical focus. Only two studies reported using theory to underpin the design of this complex intervention. There was large heterogeneity across all studies as well as a lack of clinical trials to provide definitive evidence on the programme design, setting, type of intervention, patient criteria, delivery, duration and outcome measures used.

CONCLUSION

A standardised prehabilitation programme for lung cancer patients does not yet exist. Future lung cancer prehabilitation programmes should take into account patient led values, needs, goals, support structures and beliefs, as these factors can affect the delivery and engagement of interventions. Future research should consider using a conceptual framework to conceptualise the living with and beyond cancer experience to help shape and inform personalised prehabilitation services.

Implementation of an enhanced recovery program for complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in a referral center: a case control prospective study

Objectives

Current recommendations regarding enhanced recovery programs (ERPs) after complete cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are based on a low level of evidence. The aim of this study is to evaluate the effect of implementing an adapted ERP for CCRS and HIPEC in a referral center.

Methods

We conducted a study with a prospective group of 44 patients (post-ERP group) who underwent CCRS with HIPEC between July 2016 and June 2018, the period during which ERP was implemented. This group was compared to a second retrospective group of 21 patients who underwent CCRS with HIPEC between June 2015 and June 2016, during which ERP was not yet implemented (pre-ERP group).

Results

The ERP compliance rate was 65% in the post-ERP group. The hospital length of stay (HLS) was shorter in the post-ERP group: 24.9 days (IQR 11–68, pre-ERP group) vs. 16.1 days (IQR 6–45, post-ERP group), as was the major morbidity rate (pre-ERP group=33.3% vs. post-ERP group=20.5%). The nasogastric tube, urinary catheter and abdominal drains were all retrieved faster in the post-ERP group.

Conclusions

The implementation of an adapted ERP after CCRS with HIPEC procedures reduces morbidity and shortens the HLS.

Considerations for multimodal prehabilitation in women with gynaecological cancers: a scoping review using realist principles

Background

There is increasing recognition that prehabilitation is important as a means of preparing patients physically and psychologically for cancer treatment. However, little is understood about the role and optimal nature of prehabilitation for gynaecological cancer patients, who usually face extensive and life-changing surgery in addition to other treatments that impact significantly on physiological and psychosexual wellbeing.

Review question

This scoping review was conducted to collate the research evidence on multimodal prehabilitation in gynaecological cancers and the related barriers and facilitators to engagement and delivery that should be considered when designing a prehabilitation intervention for this group of women.

Methods

Seven medical databases and four grey literature repositories were searched from database inception to September 2021. All articles, reporting on multimodal prehabilitation in gynaecological cancers were included in the final review, whether qualitative, quantitative or mixed-methods. Qualitative studies on unimodal interventions were also included, as these were thought to be more likely to include information about barriers and facilitators which could also be relevant to multimodal interventions. A realist framework of context, mechanism and outcome was used to assist interpretation of findings.

Results

In total, 24 studies were included in the final review. The studies included the following tumour groups: ovarian only (n = 12), endometrial only (n = 1), mixed ovarian, endometrial, vulvar (n = 5) and non-specific gynaecological tumours (n = 6). There was considerable variation across studies in terms of screening for prehabilitation, delivery of prehabilitation and outcome measures. Key mechanisms and contexts influencing engagement with prehabilitation can be summarised as: (1) The role of healthcare professionals and organisations (2) Patients’ perceptions of acceptability (3) Factors influencing patient motivation (4) Prehabilitation as a priority (5) Access to prehabilitation.

Implications for practice

A standardised and well evidenced prehabilitation programme for women with gynaecological cancer does not yet exist. Healthcare organisations and researchers should take into account the enablers and barriers to effective engagement by healthcare professionals and by patients, when designing and evaluating prehabilitation for gynaecological cancer patients.

Postoperative complications and critical care management after cytoreduction surgery and hyperthermic intraperitoneal chemotherapy: A systematic review of the literature

BACKGROUND

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a comprehensive treatment option performed for peritoneal surface malignancies. Postoperatively almost all patients are transferred to the intensive care unit electively.

AIM

To describe the common and rare postoperative complications, postoperative mortality and their critical care management after CRS-HIPEC.

METHODS

The authors assessed 54 articles for eligibility. Full text assessment identified 14 original articles regarding postoperative complications and critical care management for inclusion into the final review article.

RESULTS

There is an exaggerated metabolic and inflammatory response after surgery which may be termed as physiological in view of the nature of surgery combined with the use of heated intraperitoneal chemotherapy with/out early postoperative intravenous chemotherapy. The expected postoperative course is further discussed. CRS-HIPEC is a complex procedure with some life-threatening complications in the immediate postoperative period, reported morbidity rates between 12%-60% and a mortality rate of 0.9%-5.8%. Over the years, since its inception in the 1980s, postoperative morbidity and survival have significantly improved. The commonest postoperative surgical complications and systemic toxicity due to chemotherapy as reported in the last decade are discussed.

CONCLUSION

CRS-HIPEC is associated with a varying rate of postoperative complications including postoperative deaths and needs early suspicion and intensive care monitoring.

Role of prophylactic HIPEC in non-metastatic, serosa-invasive gastric cancer: a literature review

The role of prophylactic hyperthermic intraperitoneal chemotherapy (p-HIPEC) in serosa invasive gastric cancers without gross or microscopic peritoneal disease, to reduce the rate of peritoneal relapse is an area of ongoing research. Although p-HIPEC is effective in reducing the rate of peritoneal relapse and improving disease free and overall survival with or without adjuvant chemotherapy, when added to curative surgery in locally advanced, non-metastatic gastric cancers, the available literature is at best, heterogeneous, centre-specific and skewed. Apart from that, variations in the systemic therapy used, and the presence of the associated nodal disease further complicate this picture. To evaluate the role of p-HIPEC the PubMed, Cochrane central register of clinical trials, and the American Society of Clinical Oncology (ASCO) meeting library were searched with the search terms, “gastric”, “cancer”, “hyperthermic”, “intraperitoneal”, “chemotherapy”, prophylactic”, “HIPEC” in various combinations, and a critical review of the available evidence was done. Although p-HIPEC is a promising therapy in the management of locally advanced gastric cancers, the current evidence is insufficient to recommend its inclusion into routine clinical practice. Future research should be directed towards identification of the appropriate patient subset and towards redefining its role with current peri-operative systemic therapies.
