Phase angle in patients with peritoneal carcinomatosis undergoing cytoreductive surgery and hyperthermic intraoperative chemotherapy

Treatment of colon cancer using a novel approach comprising cytoreductive surgery in combination with hyperthermic intraperitoneal chemotherapy and intraoperative radiation therapy.

e15573 Background: Approximately 10% of colon cancer (CCa) develop peritoneal carcinomatosis. Studies have found that the administration of hyperthermic intraoperative chemotherapy (HIPEC) during cytoreductive surgery (CRS) can reduce the risk of recurrence and development of peritoneal carcinomatosis (PC). Additionally, intraoperative radiotherapy (IORT) has been shown to effectively treat and blunt neoplasm growth. However, no reports of the impact of concurrent HIPEC and IORT in CRS on CCa are available. Methods: We retrospectively reviewed the medical records of CCa patients with PC who received HIPEC and IORT during CRS. Demographics, treatment details, PC indexes (PCI), completeness of cytoreduction scores (CCS), and operative complications were recorded. Subsequently, overall survival (OS) was defined as the time period from surgery until death or loss of follow-up, and recurrence-free survival (RFS) was defined as the period from surgery until recurrence or loss of follow-up. Univariate hazard ratios (HR) were used to check for prognostic factors. Results: 17 CCa patients were included in our analysis. Patient characteristics are summarized in Table 1. The pT staging was T0 in 1 (5.9%), T3 in 6 (35.3%), T4a in 4 (23.5%), and T4b in 6 (35.3%). The pN staging was N0 8 (47.1%), N1a in 4 (23.5%), N1b in 2 (11.8%), N1c in 2 (11.8%), and N2b in 1 (5.9%). Finally, the pM staging was M0 in 8 (47.1%), M1a in 4 (23.5%), M1b in 2 (11.8%), and M1c in 3 (16.4%). PCI was ≤6 in 13 (76.5%) patients. The CCS was 0-1 in all, but two, patients. 1 patient had a positive resection margin. 8 (47.1%) received cisplatin with mitomycin C during HIPEC, followed by mitomycin alone (29.4%), reduced doses of cisplatin + mitomycin C (17.6%), and a reduced dose of mitomycin C alone (5.9%). Reduced dosage was due to old age in 3 and renal impairment in 1 patient. There were no intraoperative complications or HIPEC-related adverse effects. Two patients received two doses of IORT. 4 (23.5%) patients had postoperative complications, of which two complications were Clavein-Dindo grade 4a. Recurrence occurred in 8 (47.1%) patients, and 4 (23.5%) patients passed away. The median OS was not reached, and the RFS was 19 months. PCI > 6 (HR: 12.6, 95% CI: 1.6-256.8) and postoperative complication of grade 4 (HR: 8.6, 95% CI: 1-73) were associated with poor OS. Only PCI > 6 was associated with poor RFS (HR: 10.4, 95% CI: 1.7-80.8). Conclusions: Postoperative complications in HIPEC+IORT during CRS are comparable to other accepted treatments for CCa. Large, double-arm studies are needed to compare the effectiveness of this treatment. [Table: see text]

Nursing care for cytoreduction and hyperthermic intraoperative chemotherapy in an Intensive Care Unit: a scoping review.

To map postoperative nursing care for critically ill adult and older patients admitted to the Intensive Care Unit after cytoreduction surgery with hyperthermic intraoperative intraperitoneal chemotherapy. TScoping review according to the JBI methodology, with articles extracted from databases and gray literature, with no language or publica-tion date delimitation. The studies selection and results extraction process was carried out by two independent reviewers, using the soft-ware EndNote® and Rayyan®. PRISMA Extension for Scoping Review was used for the writing, with registration on the Open Science Framework. Forty-two studies were selected. The analysis revealed 72 types of care grouped into 14 care areas. The use of an epidural catheter for anal-gesia, optimization of individualized hemodynamic status, and strict control of fluid balance were the most cited care measures. The mapping identified post-operative nursing care similar to those for major surgeries for patients recovering in the Intensive Care Unit, with an indication of the use of personal protective equipment by professionals when handling tubes in the first 48 hours of admission.

Outcomes Following Cytoreductive Surgery and Hyperthermic Intraoperative Thoraco-Abdominal Chemotherapy with Diaphragm Resection for Peritoneal Carcinomatosis: A Retrospective Cohort Study.

We aimed to evaluate the safety and efficacy of hyperthermic intraoperative thoraco-abdominal chemotherapy (HITAC) and cytoreductive surgery (CRS) for peritoneal carcinomatosis (PC) patients who underwent diaphragm resection. PC patients who underwent CRS with diaphragm resection were selected from a prospectively established database and were divided into hyperthermic intraperitoneal chemotherapy (HIPEC) and HITAC groups. The clinicopathological characteristics, treatment-related variables, perioperative adverse events (AEs), and survival outcomes were compared between the two groups. Of 1168 CRS + HIPEC/HITACs, 102 patients were enrolled-61 HITAC patients and 41 HIPEC patients. In the HITAC and HIPEC groups, the incidence of grade III-V AEs was 29.5% versus 34.1% (p = 0.621). The pleural progression rates were 13.2 versus 18.9% (p = 0.462) and the median overall survival (OS) was 50.5 versus 52.7 months (p = 0.958). Median time to progression (TTP) in thoracic disease was not reached. There was no significant difference in perioperative AEs, TTP, and OS for total patients and the completeness of cytoreduction (CC) score subgroups (p > 0.05). Age ≥ 60years (hazard ratio [HR] 4.162, p = 0.026) was an independent risk factor influencing pleural progression, and primary malignant peritoneal mesothelioma (MPM; HR 2.749, p = 0.016) and the presence of two or more serious AEs (SAEs; HR 7.294, p = 0.001) were independent risk factors influencing OS. HITAC can be performed in carefully selected PC patients who underwent diaphragm resection, with no worsening of the safety profile and a possible benefit for pleural progression. In those patients, age ≥ 60 years is associated with a shorter TTP of thoracic disease, while primary MPM and two or more perioperative SAEs are associated with worse OS.

Extended pleurectomy/decortication and hyperthermic intraoperative intrapleural cisplatin perfusion for malignant pleural mesothelioma

ObjectiveTo evaluate the efficacy of multimodality treatment including extended pleurectomy/decortication (P/D) and hyperthermic intraoperative chemotherapy (HIOC) with cisplatin for malignant pleural mesothelioma (MPM), we investigated the pharmacokinetics of platinum, adverse events after HIOC, and survival outcome. MethodsFifty-three patients with pathologically diagnosed MPM (cT1-3N0-1M0, excluding sarcomatoid) underwent an extended P/D and HIOC (cisplatin 80 mg/m2 in saline 2 L, 42°C, 60 minutes) since 2011. The protocol includes postoperative 4 cycles of cisplatin and pemetrexed. Platinum concentrations in the perfusate (before and after) and the serum (1, 2, 4, 8, 24, 48, 72 hours after perfusion) were measured in 10 patients. Mortality and morbidity, especially adverse events of renal function, were investigated, and survival and affecting factors were examined. ResultsAll patients obtained macroscopic complete resection and pathologic staging revealed as follows: T1/2/3/4: 12/8/23/10, N0/1: 36/17, stage 1A/1B-3A/3B: 12/31/10, respectively. Platinum concentrations in the perfusate indicated that 28% of the dose remained in the pleural cavity, and the maximum concentration in the serum was 0.91 μg/mL. Six patients (11%) showed elevated max-creatinine (>2 mg/dL) postoperatively. Two patients (4%) received renal-replacement therapy, and one was weaned before discharge. There was no 30-day mortality and one in-hospital death (1.9%). Forty-six patients (87%) received multiple cycles of perioperative systemic chemotherapy. Median overall survival (OS) and disease-free survival (DFS) were 52.4 months and 18.7 months. Patents with stage 1A demonstrated a 5-year OS of 67.3% and a median DFS of 67.1 months, and patients with stage 1B-3A demonstrated a 5-year OS of 50.1% and a median DFS of 20.4 months. Univariate analysis showed histological subtype, p-T, p-stage, and multimodality treatment as significant factors affecting OS. Multivariate analysis revealed histology, p-stage, and multimodality as independent. ConclusionsExtended P/D and HIOC with cisplatin for MPM is acceptable with limited acute kidney injury. This multimodality protocol provides promising favorable survival for stage 1A-3A disease.

Hyperthermic intraoperative chemotherapy (HIOC) for Stage IVa thymic malignancy may improve 5-year disease-free survival.

Stage IVa thymic malignancy has limited treatments. This study evaluated whether hyperthermic intraoperative chemotherapy(HIOC) after radical resection of Stage IVa thymic malignancy improves survival. All patients who underwent resection, with or without HIOC, for Stage IVa thymic malignancy at a single center from 1990 to 2021 were reviewed. Thirty-four patients were identified; 22 surgery-only versus 12 surgery and HIOC (60 mincisplatin regimen 175 mg/m2 ). Demographics and comorbidities were similar between groups. Three patients in each group were carcinomas; remainder were thymomas. Thirty-two patients underwent attempted macroscopic complete resection; 22 operations succeeded, 68.8%. Significant complications were similar between groups, 18.2% surgery-only versus 25.0% HIOC, p = 0.68. Median time to recurrence trended longer for HIOC patients (42.9 vs. 32.9 months in surgery-only, p = 0.77). Overall survival, 5-year, was similar (75.8% HIOC vs. 76.2% surgery-only, p = 0.91). On stratified analysis, thymoma patients with macroscopic complete resection and HIOC experienced similar 5-year Overall (80.0% vs. 100.0% surgery-only, p = 0.157) but longer trending 5-year disease-free (85.7% vs. 40.0%, p = 0.18) and 5-year locoregional recurrence-free survival (85.7% vs. 68.6%, p = 0.75). This retrospective cohort study treating Stage IVa thymic malignancy with radical pleurectomy, with or without HIOC, found addition of HIOC-signaled delayed recurrence and improved disease-free survival.

Results of treatment of cancer patients with peritoneal carcinomatosis

Objective: At present, common forms of cancer of different localization can not be ignored. New approaches to the treatment of metastatic lesions have some success in clinical application. This study is devoted to the experience of using the technology of cytoreductive surgery and hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in practice, as well as the analysis of overall and relapse-free survival in the examined groups of patients.
 Patients and methods: A total of 119 people were recruited from 2013 to 2020 inclusive. Patients were divided into two groups: the clinical control group (n = 53) consisted of individuals who underwent suboptimal cytoreduction; in the main group (n = 66) there were patients who performed optimal or complete cytoreductive volume and in some cases underwent intraoperative hyperthermic chemotherapy. Patients diagnosed with stage IIIC ovarian cancer were treated. In the initial analysis of these groups, time indicators (period before surgery, duration of surgery, number of postoperative bed-days), as well as the presence and nature of complications in the postoperative period were taken into account.
 Results: The analysis showed an increase in relapse-free survival from 10 months in the control group to 13-19 months in the main group, also significantly increased (from 5 to 22%) the number of complications of class III-IV in HIPEC.
 Conclusion: The study is prospective and retrospective, recruitment into groups has been conducted since 2013. Observation of the studied groups continues. The expected results will be a significant discrepancy between overall and recurrence-free survival in the study groups.

Induction Chemotherapy Followed by Pleurectomy Decortication and Hyperthermic Intraoperative Chemotherapy (HITHOC) for Early-Stage Epitheliod Malignant Pleural Mesothelioma-A Prospective Report.

Malignant pleural mesothelioma (MPM) is an aggressive disease with poor prognosis and the current treatment for early-stage MPM is based on a multimodality therapy regimen involving platinum-based chemotherapy preceding or following surgery. To enhance the cytoreductive role of surgery, some peri- or intra-operative intracavitary treatments have been developed, such as hyperthermic chemotherapy, but long-term results are weak. The aim of this study was to report the post-operative results and mid-term outcomes of our multimodal intention-to-treat pathway, including induction chemotherapy, followed by surgery and Hyperthermic Intraoperative THOracic Chemotherapy (HITHOC) in the treatment of early-stage epithelioid MPM. Since 2017, stage I or II epithelioid MPM patients have been inserted in a surgery-based multimodal approach comprising platinum-based induction chemotherapy, followed by pleurectomy and decortication (P/D) and HITHOC with cisplatin. The Kaplan–Meier method was used to estimate overall survival (OS), disease-free survival (DFS) and progression-free survival (PFS). During the study period, n = 65 patients affected by MPM were evaluated by our institutional Multidisciplinary Tumour Board; n = 12 patients with stage I-II who had no progression after induction chemotherapy underwent P/D and HITHOC. Post-operative mortality was 0, and complications developed in n = 7 (58.3%) patients. The median estimated OS was 31 months with a 1-year and 3-year OS of 100% and 55%, respectively. The median PFS was 26 months with 92% of a 1-year PFS, whereas DFS was 19 months with a 1-year DFS rate of 83%. The multimodal treatment of early-stage epithelioid MPM, including induction chemotherapy followed by P/D and HITHOC, was well tolerated and feasible with promising mid-term oncological results.

Impact of Ketamine on Opioid Use and Persistent Pain After Cytoreductive Surgery with Hyperthermic Chemotherapy.

BackgroundPersistent pain and opioid use can be devastating after cytoreductive surgery (CRS) and hyperthermic intraoperative chemotherapy (HIPEC).MethodsWe conducted a retrospective study to investigate the impact of ketamine use on postoperative complications and persistent and chronic pain after CRS-HIPEC.ResultsKetamine reduced perioperative opioid use before and after implementation of recovery after surgery programs. Ketamine did not impact the formation of persistent and chronic pain formation and long-term opioid use. Postoperative complications and postoperative re-operations were independent predictors of persistent pain. Interestingly, the risk of having a complication was increased by 1% for every doubling in opioids used intraoperatively.ConclusionKetamine use reduces perioperative opioid consumption in patients undergoing CRS-HIPEC, but it is not associated with improvements in long-term opioid use and chronic pain.

Narrative review of theoretical considerations regarding HITHOC between past and future.

Hyppocrates constructed the medicines-surgery-energy triangle which includes all therapeutical modalities. Hyperthermic intraoperative chemotherapy (HITHOC) is a synergy-based single stage multimodality treatment encompassing the locoregional manifestation of the systemic malignant process. Pleural space, thermal effect, lavage/irrigation and chemotherapy represent the basic science ports of the network hub: HITHOC. The malignant transformation and process of the pleural surface (and underlying lung) challenges space management and tissue control. Thermotherapy without local chemotherapy is insufficient, similar to the normothermic local irrigation aligned with anticancer agents. The local administration of combined heat-transfer fluid and chemotherapy with or without subsequent surgical removal offers reasonable outcome in extensive primary pleural neoplasms (malignant mesothelioma), advanced (> Stage IIIA) NSCLC, functionally inoperable lung cancer and pleural carcinosis from extrathoracic malignancies. Measured by symptom-free survival and the quality of life, HITHOC in its present form, offers a modest yet fully substantiated solution. HITHOC in combination with the local application of targeted therapy and/or immunotherapy administered in the pleural space are currently under investigation. Additional development including new acting substances, their solvents and the means regarding surgical delivery and anesthesiology techniques are sign posts up ahead. Level 2 evidence are required in order to stepping up the recommendation levels, rewriting protocols and guidelines, in which HITHOC earns its revered position in the decision making process it deserves.

Delayed genital necrosis after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy with Mitomycin-C

IntroductionGenital necrosis (GN) is a rare complication of cytoreductive surgery with hyperthermic intraoperative chemotherapy (CRS/HIPEC) which can be confused with necrotizing fasciitis. We present an analysis of GN after CRS/HIPEC to define its natural history. MethodsWe identified patients with GN after CRS/HIPEC at two peritoneal surface malignancy institutions. Patient demographic, surgical, and postoperative data were extracted from prospective databases. ResultsOf 1597 CRS/HIPECs performed, 13 patients (0.8%) had GN. The median age was 57 years (IQR: 49–64) and 77% (n = 10) were male. Mitomycin-C was the perfusion agent in all cases of GN (100%). The median time to GN onset after CRS/HIPEC was 64 days (IQR: 60–108) and 2 (15%) patients were receiving systemic chemotherapy at the time of GN onset. Symptoms included severe pain (100%), edema (100%), labial or scrotal skin ulceration (92%), signs of infection (39%), and fever (15%). Seven (54%) patients had thrombocytosis >400 ∗109/L, whereas coagulation tests were within normal reference range in 100% cases. All patients initially underwent conservative treatment, with antibiotic therapy administered in 62% (n = 8). Surgical debridement was performed in 9 (70%) cases with median time after GN onset of 57 (IQR: 8–180). ConclusionGN is a debilitating complication after CRS/HIPEC with delayed onset and a protracted clinical course. Optimal treatment results could be achieved with initial conservative management until complete lesion demarcation followed by surgical debridement. The pathophysiology of GN is unclear, and we call for other researchers attention to better understand the complication and prevention.

Pre-surgical assessment of dietary intake of patients with peritoneal carcinomatosis who are undergoing cytoreductive surgery and hyperthermic intraoperative chemotherapy. Preliminary results

Rationale: Patients with peritoneal carcinomatosis who are undergoing cytoreductive surgery and hyperthermic intraoperative chemotherapy (CRS-HIPEC) are at high nutritional risk. As a consequence, it is recommended to carry out nutrition screening and assessment that include a dietary intake. Assess dietary intake and check the adequacy of the intake to the recommendations from the ESPEN guidelines for cancer patients* (25-30 kcal/kg/day and 1-1.5 g/kg/day of protein).

Hyperthermic intraoperative intrapleural chemotherapy and surgical cytoreduction as part of multimodal treatment of malignant pleural mesothelioma – case report

Malignant pleural mesothelioma is one of the most aggressive malignancies with a very poor prognosis. Multimodal treatment consisting of three modalities – chemotherapy, radiotherapy and cytoreductive surgery is optimal. The use of new therapeutic modalities, such as hyperthermic intraoperative intrapleural chemotherapy or photodynamic therapy can improve the current results of mesothelioma treatment. Combined hyperthermic intraoperative chemotherapy and cytoreductive surgery as part of multimodal therapy of malignant mesothelioma has been used since 2017 at the 1st Department of Surgery of University Hospital Olomouc. The authors report the case of a 47-year-old man with malignant epithelioid mesothelioma of the left pleural cavity. Following neoadjuvant chemotherapy, this patient underwent extrapleural pneumonectomy with intraoperative intracavitary hyperthermic chemotherapy. The postoperative period was complicated by circulatory instability and later by tension fluidothorax with signs of heart failure. Currently, 8 months have elapsed from the surgery and the patient remains without any signs of recurrence.

A case report of appendix mucinous adenocarcinoma that recurred after additional surgery and a brief literature review

BackgroundThe clinical incidence of appendiceal mucinous adenocarcinoma is low. Moreover, the case reports of postoperative relapse after surgery are rarely based on literature search results. Here, we report such a case spanning nearly 7 years and and review the relevant literature.Case presentationA 50-year-old female underwent additional surgery after appendectomy, and pathological examination confirmed mucinous adenocarcinoma. The patients underwent HIPEC (hyperthermic intraoperative chemotherapy) and adjuvant chemotherapy. Twenty-six months after the previous surgeries, another surgery, HIPEC, and adjuvant chemotherapy were performed again due to tumour recurrence. To date, the follow-up time is 43 months, and no recurrence or metastasis has been found.ConclusionsAppendix mucinous adenocarcinoma has a poor prognosis and the diagnosis depends on pathological and immunohistochemical examinations. Its clinical manifestations are non-specific, and CRS + HIPEC should be used for treatment, which is safe and effective.

Acute kidney injury after cytoreductive surgery and hyperthermic intraoperative cisplatin chemotherapy for malignant pleural mesothelioma

ObjectivesCytoreductive surgery with hyperthermic intraoperative chemotherapy with cisplatin has been used successfully to treat malignant pleural mesothelioma, a highly aggressive malignancy that is rapidly fatal in most cases. We hypothesized that the combination of ischemic injury with nephrotoxic injury from cisplatin would result in high rates of acute kidney injury. MethodsWe conducted an observational study in 503 patients to study the risks and outcomes of acute kidney injury after surgical resection of malignant pleural mesothelioma. Eligible subjects underwent extrapleural pneumonectomy or pleurectomy/decortication with or without hyperthermic intraoperative chemotherapy. Acute kidney injury was defined as an increase in creatinine of 26.5 μmol/L or greater within 48 hours of surgery or a 50% or greater increase over 7 days. ResultsAcute kidney injury developed in 243 patients (48.3%). Severe acute kidney injury requiring renal replacement therapy developed in 16 patients (3.2%). Major significant predictors for acute kidney injury included male sex (odds ratio, 2.98; P < .001), intraoperative cisplatin administration (odds ratio, 3.12; P < .001), previous cisplatin exposure (odds ratio, 1.96; P = .02), hypertension (odds ratio, 1.57; P = .02), and longer surgical time (odds ratio, 1.15 per hour; P = .02). Compared with patients without acute kidney injury, those with severe acute kidney injury had longer length of stay (26 vs 13 days) and a 2.71-fold increased risk of death in multivariable-adjusted models. ConclusionsAcute kidney injury is common after cytoreductive surgery with hyperthermic intraoperative chemotherapy with cisplatin and is associated with poor long-term outcomes. Strategies to prevent postoperative acute kidney injury are needed to improve multimodal treatment of malignant pleural mesothelioma.

Cerebral infarction after left upper lung lobectomy with central vascular ligation.

BackgroundThrombus of the pulmonary vein (PV) stump is reportedly more frequent after left upper lobectomy than after other lobectomies, risking postoperative cerebral infarction (PCI). We have performed central vascular ligation before vascular dissection to improve the safety of surgical stapling. The effects of central vascular ligation in terms of PV stump thrombus and PCI are uncertain.MethodsThis study retrospectively reviewed the records of patients who underwent left upper lobectomy at a single center (Hokkaido Cancer Center, Sapporo, Japan) between November 1, 2008 and July 31, 2018. Relationships between PCI, PV stump thrombus and background characteristics were investigated and analyzed.ResultsAll 208 cases of left upper lobectomy underwent central vascular ligation of the PV during this study. PCI occurred in 8 of the 208 patients. PV stump thrombus was detected in 14 of the 132 patients. In comparison with no-PCI cases, PCI cases showed significantly higher rates of comorbidity with cardiovascular disease (P=0.02), double cancer within 5 years (P=0.04), intraoperative hyperthermic chemotherapy (P=0.02), postoperative intrapleural inflammation (P=0.02) and postoperative PV stump thrombus (P=0.04). Presence of both comorbid cardiovascular disease (odds ratio, 18.4) and intraoperative hyperthermic chemotherapy (odds ratio, 30.4) was associated with higher risk of PV stump thrombus than presence of none of these factors. Cerebral infarction within 30 days postoperatively was seen in only 2 of the 208 cases (1.0%).ConclusionsCentral ligation of the PV may prevent postoperative early cerebral infarction. Further study of the effectiveness of this method for preventing PV stump thrombus is needed.

Manejo de carcinomatosis peritoneal con citorreducción más quimioterapia hipertérmica intraoperatoria (HIPEC)

Introducción: la citorreducción más quimioterapia hipertérmica intraoperatoria (HIPEC) aborda la carcinomatosis peritoneal (CP) como una enfermedad locorregional, con respuesta adecuada en la supervivencia considerando la severidad de la patología. La agresividad del procedimiento se asocia con altos índices de morbimortalidad. Objetivo: evaluar la supervivencia global y libre de enfermedad a 1 año en pacientes con CP, en quienes se realizó tratamiento mediante citorreducción más HIPEC en el Hospital Infantil Universitario de San José entre enero 2016 y diciembre 2017. Metodología: estudio observacional de una cohorte con CP de diferentes etiologías que recibieron citorreducción más HIPEC, se obtuvo información a partir de las historias clínicas. Resultados: se incluyeron 10 casos con una mediana de edad de 49 años (RIC 43-54) y CP de origen primario en apéndice (60%, n=6), colon (20%, n=2) y ovario (20%, n=2). El índice de carcinomatosis peritoneal (ICP) presentó una mediana de 14.5 (RIC 6-24). Se observó recaída en 3 pacientes y 4 desenlaces fatales. Se estimó una supervivencia global de 54% y libre de enfermedad de 58% a un año. Conclusión: se encontraron mejores resultados en supervivencia global y libre de enfermedad a un año que los descritos en quimioterapia sistémica. Es importante la selección estricta de los pacientes, así como efectuar estudios con un mayor número para determinar con evidencia la relación entre el procedimiento y la supervivencia global y libre de enfermedad.

Intraoperative Hyperthermic Chemotherapy for advanced Breast Cancer

Background: Hyperthermic Chemotherapy is well established now in surgical oncology the management of peritoneal surface malignancy, intrathoracic pleural malignancy and even in hyperthermic isolated limb perfusion. Benefits are attributed to high local concentration of administered drug and reduced systemic toxicity with hyperthermia increasing the effect of the chemotherapeutic agent.

Perioperative anesthetic management of patients with malignant pleural mesothelioma undergoing cytoreductive surgery and intraoperative chemotherapy

Abstract Introduction Cytoreductive surgery with hyperthermic intraoperative chemotherapy (HITHOC) is a therapeutic option for treatment of malignant pleural mesothelioma. Anaesthetic management might be challenging. Patients and methods A descriptive analysis of a case series is presented. Seven patients with malignant pleural mesothelioma diagnostic undergoing HITHOC surgery were studied. Combined general and epidural anaesthesia were administered. An intensive haemodynamic monitorization was implemented. Data regarding perioperative course was analyzed. Results Between May 2015 and October 2018 7 patients underwent HITHOC procedure. Blood transfusions were administered in all patients, and 5 of the 7 patients required vasoactive drug administration. Extubation at the end of the procedure was able in 6 of the 7 patients. The median length of stay in ICU was 4 days, and 29 days for the whole hospitalary stay. No significant postoperative pain was observed. Conclusions HITHOC surgery is a complex procedure in which several haemodynamic changes occur. An intensive intraoperative monitorization was useful for controlling complications.
