Readmissions after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy-a national population-based study

Epidemiology of psychiatric disorders following cytoreductive surgeries plus hyperthermic intraperitoneal chemotherapy: a prospective cohort analysis

The peritoneal surface malignancy (PSM) is an advanced disease, the prognosis of which has been radically improved since the development of cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC). These procedures are associated with many complications. However, very few data are available regarding the psychiatric morbidities that might occur. The present study assessed the epidemiology of depressive mood and anxiety during the 6 months following the procedure. The analysis of a prospective cohort that included patients who underwent CRS with or without HIPEC between December 2016 and December 2019 was performed. A total of 115 patients were included. During the 6-months follow-up, the mean (SD) Hospital Anxiety and Depression Scale -D (HADS-D) score was 7.8 (48) and a significant increase compared with the pre-operative period (t(49) = - 4.36, p < 0.005) was found. Thirty-seven patients (32%) had a HADS-D score higher than 7. The incidence of a HADS-D score higher than 7 during the follow-up was 0.05 patient per patient-month. Anxiety and the overall mental disorders intensity scores also increased. The results showed an important increase of mental disorders and their intensity during the 6-months following a CRS with or without HIPEC.

The impact on postoperative outcomes of intraoperative fluid management strategies during cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

BACKGROUND

The impact of intraoperative fluid management during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) on postoperative outcomes has been poorly investigated. This study aimed to retrospectively evaluate the impact of intraoperative fluid management strategy on postoperative outcomes and survival.

METHODS

509 patients undergoing CRS and HIPEC at Uppsala University Hospital/Sweden 2004-2017 were categorized into two groups according to the intraoperative fluid management strategy: pre-goal directed therapy (pre-GDT) and goal directed therapy (GDT), where a hemodynamic monitor (CardioQ or FloTrac/Vigileo) was used to optimize fluid management. Impact on morbidity, postoperative hemorrhage, length-of-stay and survival was analyzed.

RESULTS

The pre-GDT group received higher fluid volume compared to the GDT group (mean 19.9 vs. 16.2 ml/kg/h, p < 0.001). Overall postoperative morbidity Grade III-V was higher in the GDT group (30% vs. 22%, p = 0.03). Multivariable adjusted odds ratio (OR) for Grade III-V morbidity was 1.80 (95%CI 1.10-3.10, p = 0.02) in the GDT group. Numerically, more cases of postoperative hemorrhage were found in the GDT group (9% vs. 5%, p = 0.09), but no correlation was observed in the multivariable analysis 1.37 (95%CI 0.64-2.95, p = 0.40). An oxaliplatin regimen was a significant risk factor for postoperative hemorrhage (p = 0.03). Mean length of stay was shorter in the GDT group (17 vs. 26 days, p < 0.0001). Survival did not differ between the groups.

CONCLUSION

While GDT increased the risk for postoperative morbidity, it was associated with shortened hospital stay. Intraoperative fluid management during CRS and HIPEC did not affect the postoperative risk for hemorrhage, while the use of an oxaliplatin regimen did.

Re-do cytoreductive surgery with hyperthermic intra-peritoneal chemotherapy (HIPEC): Risk factors and complications

ABSTRACT

An effective multi-modal treatment option for patients with peritoneal surface metastatic malignancies has progressed and developed over the decades as cytoreductive surgery (CRS), and hyperthermic intra-peritoneal chemotherapy (HIPEC) delivers highly concentrated, heated chemotherapy drugs directly to the abdomen during surgery. Peritoneal metastasis and high staging abdominal malignancies were considered incurable and end up with the palliation only; the CRS+HIPEC combination approach increases the median survival rate and gives a better quality of life to these patients. It is a complicated surgery which poses a high rate of complications and challenges which are difficult to manage and requires a multi-disciplinary approach. The aim of this study is to elaborate the perioperative possible physiological changes, risk factors, and related complications after re-do HIPEC.

Complications and Mortality Rate of Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy: Italian Peritoneal Surface Malignancies Oncoteam Results Analysis

BACKGROUND

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy may significantly improve survival for selected patients with peritoneal surface malignancies, but it has always been criticized due to the high incidence of postoperative morbidity and mortality.

METHODS

Data were collected from nine Italian centers with peritoneal surface malignancies expertise within a collaborative group of the Italian Society of Surgical Oncology. Complications and mortality rates were recorded, and multivariate Cox analysis was used to identify risk factors.

RESULTS

The study included 2576 patients. The procedure was mostly performed for ovarian (27.4%) and colon cancer (22.4%). The median peritoneal cancer index was 13. Overall postoperative morbidity and mortality rates were 34% and 1.6%. A total of 232 (9%) patients required surgical reoperation. Multivariate regression logistic analysis identified the type of perfusion (p ≤ 0.0001), body mass index (p ≤ 0.0001), number of resections (p ≤ 0.0001) and colorectal resections (p ≤ 0.0001) as the strongest predictors of complications, whereas the number of resections (p ≤ 0.0001) and age (p = 0.01) were the strongest predictors of mortality.

CONCLUSIONS

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is a valuable option of treatment for selected patients with peritoneal carcinomatosis providing low postoperative morbidity and mortality rates, if performed in high-volume specialized centers.

Predicting Early and Late Readmissions Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

Background

Postoperative readmissions not only burden the healthcare system but may also affect clinical outcomes of cancer patients. Despite this, little is known about readmissions after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), or their impact on survival outcomes.

Patients and Methods

A single-institution retrospective cohort study of CRS-HIPEC procedures from April 2001 and September 2019 was performed. Early readmission (ERA) was defined as hospitalization within 30 days of discharge post-CRS/HIPEC, while late readmission (LRA) was defined as hospitalization between day 31 and 90 after discharge. Patient demographic, oncological, and perioperative factors were analyzed to identify predictors of readmission, and comparison of survival outcomes was performed.

Results

Overall, 342 patients who underwent CRS-HIPEC were included in the study. The incidence of ERA and LRA was 18.5% and 7.4%, respectively. High-grade postoperative complication was the only independent predictor of ERA (HR 3.64, 95% CI 1.47–9.02), while comorbid hypertension (HR 2.71, 95% CI 1.17–6.28) and stoma creation (HR 2.83, 95% CI 1.23–6.50) were independent predictors for LRA. Patients with readmission had significantly worse disease-free survival than patients who had no readmission (NRA) (LRA 1.1 years, ERA 1.2 years, NRA 1.8 years, p = 0.002), and patients with LRA had worse median overall survival (2.1 years) than ERA patients (3.3 years) or patients without readmission (4.4 years) (p < 0.001).

Conclusions

Readmission following CRS-HIPEC is associated with adverse survival outcomes. In particular, LRA may portend worse prognosis than ERA.

Feasibility and outcomes of cytoreductive surgery and HIPEC for peritoneal surface malignancies in low- and middle-income countries: a single-center experience of 232 cases

BACKGROUND

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has recently emerged as a viable management option for peritoneal surface malignancy (PSM). CRS and HIPEC is a complex, multidisciplinary and resource-intensive surgical procedure. It has a steep learning curve and is associated with significant morbidity and mortality. The expertise is mostly limited to few dedicated high-volume centers located in developed countries. We present a single institutional experience of 232 cases of CRS and HIPEC performed at a tertiary care cancer center in a low- and middle-income country (LMIC).

METHODS

A multidisciplinary PSM program was initiated in 2015 at a high-volume public-sector tertiary care cancer center in North India catering largely to patients belonging to low- and middle-income groups. Perioperative protocols were developed, and a prospective structured database was created to capture data. All patients undergoing CRS and HIPEC between January 2015 and December 2020 were identified, and the data was retrospectively analyzed for clinical spectrum, surgical details, and perioperative morbidity and mortality.

RESULTS

Two hundred and thirty-two patients underwent CRS and HIPEC during the study period. Epithelial ovarian carcinoma (56.5%) was the most common malignancy treated, followed by pseudomyxoma peritonei (18.5%), colorectal carcinoma (13.4%), and malignant mesothelioma (5.6%). Optimal CRS could be achieved in 94.4% of patients. Cisplatin and mitomycin were the most common drugs used for HIPEC. A total of 28.0% of patients had morbidity including deep vein thrombosis, subacute intestinal obstruction, sepsis, burst abdomen, lymphocele, urinoma, acute renal failure, and enterocutaneous fistula. The overall treatment-related mortality was 3.5%.

CONCLUSIONS

Results of the current study indicate that it is feasible to establish a successful CRS and HIPEC program for PSM in government-funded hospitals in LMIC facing resource constraints. The most common indication for CRS and HIPEC were carcinoma of the ovary followed by pseudomyxoma peritonei and colorectal carcinoma. Overall morbidity and mortality in the current series are comparable to global standards, reported from high-income countries. A protocol-based multidisciplinary team approach, optimal patient selection, and surgical expertise can help achieve optimal outcomes in government-funded hospitals in LMIC.

Coagulopathy and Venous Thromboembolic Events Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

Background

Coagulopathy after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is recognized but few details have been studied.

Objectives

The aim of this study was to investigate changes in coagulation biomarkers and their predictive ability for venous thromboembolism (VTE).

Methods

Patients undergoing CRS and HIPEC at Uppsala University Hospital, Sweden, from 2004 to 2014 were included in a prospective study of coagulation biomarkers. Prothrombin time international normalized ratio (PT-INR), activated partial thromboplastin time (APTT), fibrinogen, antithrombin, D-dimer, and platelets were sampled on postoperative days 1, 2, 5, and 10. Logistic regression analysis was used to evaluate predictive capacity for coagulation-related complications.

Results

Overall, 380 patients were included (214 females, mean age 56 years); 38 patients had a history of thromboembolism and 57 were active smokers. Mean perioperative blood loss was 1228 mL and 231 (61%) received perioperative blood transfusions. PT-INR and APTT were elevated directly after surgery but returned to normal levels on postoperative day 5. Conversely, fibrinogen, platelet count, D-dimer, and antithrombin increased by postoperative day 5 and continued to increase up to day 10. There were 23 radiologically verified cases of VTE within 6 months. The multivariate analysis identified a completeness of cytoreduction score of 2–3 (p = 0.047) and day 2 D-dimer (p = 0.0082) as independent risk factors for postoperative VTE.

Conclusion

Significant postoperative changes in coagulation biomarkers occur with dynamic changes over 10 days postoperatively. The incidence of symptomatic VTE was low. Residual tumor at completion of surgery and elevated D-dimer on day 2 were independent risk factors for postoperative VTE.
