IntroductionNeoadjuvant chemotherapy is widely used in treatment of peritoneal metastases from colorectal cancer, but there is little scientific evidence for this approach. This study aimed to study survival in patients treated with direct surgery with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), i.e. without neoadjuvant chemotherapy.Material and methodsPatients with histopathologically confirmed peritoneal metastases from colorectal cancer that underwent first-time CRS-HIPEC with complete cytoreduction (CC0 or 1) at Karolinska University Hospital 2012–2019 were included. Patients with synchronous extraperitoneal metastases were excluded if not treated before end of follow-up. Factors associated with overall survival (OS) and disease-free survival (DFS) were evaluated using the Kaplan-Meier method and Cox regression models. The multivariable models were adjusted for sex, age, synchronous/metachronous peritoneal metastases, peritoneal carcinomatosis index (PCI), extraperitoneal metastases and the pathological tumor (T) and lymph node (N) stage of the primary tumor.ResultsIn all, 131 patients underwent complete CRS-HIPEC for peritoneal metastases without neoadjuvant chemotherapy. The median OS and DFS were 40.3 months and 12.5 months, respectively, in patients treated with direct surgery. In the multivariable model, PCI≥16 was the only variable associated with decreased OS, whereas elevated PCI, metachronous development of peritoneal metastases and synchronous extraperitoneal metastases were associated with decreased DFS. Age was not associated with an impaired prognosis.ConclusionPatients who underwent direct surgery with CRS-HIPEC had a good prognosis, with a median OS of more than 3 years. The results from this study question the need of neoadjuvant chemotherapy in all patients eligible for CRS-HIPEC. 相似文献

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 1109/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. 相似文献

BACKGROUND:
Cytoreductive surgery (CS) and intraperitoneal hyperthermic chemotherapy (IPHC) can improve outcomes for selected patients with peritoneal carcinomatosis (PC) from colorectal cancer. The presence of parenchymal hepatic metastases (HM) is considered a relative contraindication for CS and IPHC. The purpose of the current study was to compare the overall survival of patients with HM to those without and to examine predictive factors.METHODS:
This was a retrospective study of patients undergoing CS and IPHC between 1991 and 2007. Clinicopathologic information was obtained from a prospectively collected database and electronic medical records. Univariate and multivariate analyses were performed to evaluate variables predictive for overall survival.RESULTS:
There were 142 patients who underwent CS and IPHC for PC from colorectal cancer, with 14 (9.9%) patients noted to have concurrent HM. The median number and size of the liver lesions was 1 (range, 1‐7 lesions) and 3.0 cm (range, 0.4 cm‐12 cm), respectively. The median overall survival for patients with HM was 23.0 months. Two‐year and 4‐year survival rates were 43.3% and 14.4%, respectively. Patients without HM had 2‐year and 4‐year survival rates of 36.8% and 17.4%, respectively. Overall survival was not significantly different for patients with and without HM (log‐rank P = .39).CONCLUSIONS:
Patients with HM undergoing CS and IPHC for colorectal cancer were found to have no significant difference in overall survival compared with those without HM. Most patients had a single small lesion treated with a minor hepatic resection. Further study is indicated to define which patients with HM benefit most from this multimodality approach.

BackgroundPeritoneal carcinomatosis is a catabolic state and cytoreductive surgery (CRS) is a high morbidity operation. Optimising perioperative nutrition is crucial to improve outcomes. This systematic review sought to examine literature describing clinical outcomes related to preoperative nutrition status and nutrition interventions in patients undergoing CRS with hyperthermic intraperitoneal chemotherapy (HIPEC).MethodsA systematic review was registered with PROSPERO (300326). A search of eight electronic databases was undertaken on 8th May 2022 and reported according to the PRISMA statement. Studies reporting nutrition status through use of screening and assessment tools, nutrition interventions or nutrition-related clinical outcomes for patients undergoing CRS with HIPEC were included.ResultsOf 276 screened studies, 25 studies were included for review. Commonly used nutrition assessment tools for CRS-HIPEC patients included Subjective Global Assessment (SGA), sarcopenia assessment with computed tomography, preoperative albumin, and body mass index (BMI). Three retrospective studies compared SGA with postoperative outcomes. Malnourished patients were more likely to have postoperative infectious complications (p = 0.042 SGA-B, p = 0.025 SGA-C). Malnutrition was significantly associated with increased hospital length of stay (LOS) in two studies (p = 0.006, p = 0.02), and with overall survival in another study (p = 0.006). Eight studies analysing preoperative albumin levels reported conflicting associations with postoperative outcomes. BMI in five studies was not associated with morbidity. One study did not support routine nasogastric tube (NGT) feeding.ConclusionsPreoperative nutritional assessment tools, including SGA and objective sarcopaenia measures, have a role in predicting nutritional status for CRS-HIPEC patients. Optimisation of nutrition is important for preventing complications. 相似文献

Background: Selecting colorectal patients for HIPEC-surgery needs improvement. The study aim was to improve the colorectal peritoneal score (COREP) and to compare it with three other scores: peritoneal-surface disease-severity score (PSDS), colorectal-peritoneal metastases prognostic-surgical-score (COMPASS), and the CEA/PCI ratio.Method: Twelve preoperative factors were chosen to evaluate for COREP score modification. Criteria from logistical analyses were set to qualify for the modified COREP score (mCOREP). Odds ratios were used to assign score points for the eligible factors with open/close laparotomy prediction as endpoint. mCOREP was applied internally and compared with the original COREP, PSDS, COMPASS, and CEA/PCI ratio. Odds ratios, hazard ratios, and Kaplan–Meier curves were used for comparison.Results: Seven factors qualified for mCOREP: CEA, CA 19-9, CA-125, C-reactive protein, albumin, platelet count and signet-cell histology. mCOREP was superior to the original COREP. mCOREP and COMPASS scores were the only scores with independent prognostic value. The mCOREP had the best discriminatory ability between its prognostic groupings. mCOREP 11?+?had 9?months survival with half of patients being open/close surgery.Conclusion: The mCOREP has successfully been simplified while still improving its prognostic ability. The mCOREP and COMPASS scores have independent prognostic value. Patients with mCOREP 11?+?may not benefit from treatment. 相似文献

Background and objectivesA postoperative pancreatic fistula (POPF) is a critical complication after surgery for pancreatic cancer. Whether a POPF affects the long-term prognosis of pancreatic cancer cases remains controversial. This study aimed to clarify the effect of a POPF on the long-term prognosis of pancreatic cancer patients, especially after neoadjuvant chemoradiotherapy (NACRT).MethodsPatients who underwent curative pancreatectomy for pancreatic cancer between January 2012 and June 2019 at Kyoto University Hospital were retrospectively investigated. A fistula ≥ Grade B was considered a POPF.ResultsDuring the study period, 148 patients underwent upfront surgery (Upfront group), and 52 patients underwent surgery after NACRT (NACRT group). A POPF developed in 16% of patients in the Upfront group and 13% in the NACRT group (p = 0.824). In the Upfront group, development of a POPF did not have a significant effect on recurrence-free survival (p = 0.766) or overall survival (p = 0.863). However, in the NACRT group, development of a POPF significantly decreased recurrence-free survival (HR 5.856, p = 0.002) and overall survival (HR 7.097, p = 0.020) on multivariate analysis.ConclusionsThe development of a POPF decreases the survival of pancreatic cancer patients treated by surgery after NACRT. 相似文献

BackgroundPreoperative assessment of peritoneal metastases is an important factor for treatment planning and selection of candidates for cytoreductive surgery (CRS) in primary advanced stage (FIGO stages III–IV) epithelial ovarian cancer (EOC). The primary aim was to evaluate the efficacy of DW-MRI, CT, and FDG PET/CT used for preoperative assessment of peritoneal cancer index (PCI).Material and methodsIn this prospective observational cohort study, 50 advanced stage EOC patients were examined with DW-MRI and FDG PET/CT with contrast enhanced CT as part of the diagnostic program. All patients were deemed amenable for upfront CRS. Imaging PCI was determined for DW-MRI, CT, and FDG PET/CT by separate readers blinded to the surgical findings. The primary outcome was agreement between the imaging PCI and PCI determined at surgical exploration (the reference standard) evaluated with Bland-Altman statistics.ResultsThe median surgical PCI was 18 (range: 3–32). For all three imaging modalities, the imaging PCI most often underestimated the surgical PCI. The mean differences between the surgical PCI and the imaging PCI were 4.2 (95% CI: 2.6–5.8) for CT, 4.4 (95% CI: 2.9–5.8) for DW-MRI, and 5.3 (95% CI: 3.6–7.0) for FDG PET/CT, and no overall statistically significant differences were found between the imaging modalities (DW-MRI – CT, p = 0.83; DW-MRI – FDG PET/CT, p = 0.24; CT – FDG PET/CT, p = 0.06).ConclusionNeither DW-MRI nor CT nor FDG PET/CT was superior in preoperative assessment of the surgical PCI in patients scheduled for upfront CRS for advanced stage EOC. 相似文献

The median survival in patients with peritoneal carcinomatosis from colorectal adenocarcinoma is, with conventional approaches,
only about six months. Combined treatment consisting of maximum cytoreductive surgery plus intraoperative intraperitoneal
hyperthermic chemotherapy has been shown, albeit in small non-comparative series, to increase disease-free survival and overall
survival, compared with previous series. Further, a randomized trial has demonstrated better results (a median survival of
22.4 months) with cytoreduction plus intraperitoneal chemotherapy compared with conventional chemotherapy. Technical considerations,
infrastructure requirements and possible complications imply specialized centres and staff. Surgery consists of peritonectomy
of affected areas and fulguration of all macroscopic lesions. Intraperitoneal chemotherapy must reach all parts of the peritoneal
cavity and the temperature of the hyperthermic procedure must be maintained between 42–44°C. Three prognostic factors associated
with this procedure are: pathologic tumour grade, peritoneal carcinomatosis index, and cytoreductive surgery grade. 相似文献

Pseudomyxoma peritonei (PMP) is a subtype of peritoneal carcinomatosis that is traditionally treated by cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC). A growing body of evidence suggests that microbes are associated with various tumor types and have been found in organs and cavities that were once considered sterile. Prior and ongoing research from our consortium of PMP researchers strongly suggests that bacteria are associated with PMP tumors. While the significance of this association is unclear, in our opinion, further research is warranted to understand whether these bacteria contribute to the development, maintenance and/or progression of PMP. Elucidation of a possible causal role for bacteria in PMP could suggest a benefit for supplementation of antibiotics to current treatment protocols. 相似文献

PurposeTo determine the effectiveness of neoadjuvant chemotherapy (NACT) versus primary surgery on survival outcomes for resectable non-small-cell lung cancer (NSCLC) using an approach based on a meta-analysis.MethodsThe PubMed, EmBase, Cochrane library, and CNKI databases were systematically browsed to identify randomized controlled trials (RCTs) which met a set of predetermined inclusion criteria throughout January 2020. Hazard ratios (HRs) were applied for the pooled overall survival (OS) and progression-free survival (PFS) values, and the pooled survival rates at 1-year and 3-year were used as the relative risk (RR). All the pooled effect estimates with 95% confidence intervals (CIs) were calculated using the random-effects model.ResultsNineteen RCTs contained a total of 4372 NSCLC at I-III stages was selected for final meta-analysis. We noted NACT was significantly associated with an improvement in OS (HR: 0.87; 95%CI: 0.81–0.94; P < 0.001) and PFS (HR: 0.86; 95%CI: 0.78–0.96; P = 0.005). Moreover, the survival rate at 1-year (RR: 1.07; 95%CI: 1.02–1.12; P = 0.007) and 3-year (RR: 1.16; 95%CI: 1.06–1.27; P = 0.001) in the NACT group was significantly higher than the survival rate for the primary surgery group. Finally, the treatment effects of NACT versus primary surgery on survival outcomes might be different when stratified by the mean age of patients and the tumor stages.ConclusionsNACT could improve survival outcomes for patients with resectable NSCLC, suggesting its suitable future applicability for clinical practice. However, large-scale RCT should be conducted to assess the chemotherapy regimen on the prognosis of resectable NSCLC. 相似文献

Peritoneal metastasis (PM) of colorectal cancer (CRC) origin can be treated and cured. This article presents a practical guide for CRC surgeons facing a patient with PM and presents the different options of treatment at expert centers on peritoneal surface malignancies.The unexpected finding of PM could be overwhelming, especially during an emergency CRC surgery. Clear indications on managing these situations call for clarification to avoid any negative impact on the oncologic outcome of patients with CRC.All patients with PM of CRC origin must be evaluated by a tumor board or multidisciplinary team specialized in the management of peritoneal surface malignancies since currently there are available options of treatment for patients with resectable peritoneal disease, unresectable peritoneal disease, and even patients with synchronous liver metastases (LM) could benefit from a multimodal approach. 相似文献

BackgroundPressurized intraperitoneal aerosol chemotherapy (PIPAC) is increasingly used to treat patients with peritoneal cancer. A recent survey demonstrated considerable diversification of current practice of PIPAC raising issues of concern also regarding safety and efficacy. The study aim was to reach consensus on best practice of PIPAC treatment.MethodsCurrent practice was critically discussed during an expert meeting and the available evidence was scrutinized to elaborate a 33-item closed-ended questionnaire. All active PIPAC centers were then invited to participate in an online two-round Delphi process with 3 reminders at least. Consensus was defined a priori as >70% agreement for a minimal response rate of 70%.ResultsForty-nine out of 57 invited PIPAC centers participated in Delphi 1 and 2 (86%). Overall, there was agreement for 21/33 items. Consensus was reached for important aspects like advanced OR ventilation system (91.8%), remote monitoring (95.9%), use of the PRGS (85.7%) and use of a safety checklist (98%). The drug regimens oxaliplatin (87.8%) and cisplatin/doxorubicin (81.6%) were both confirmed by the expert panel. Important controversies included number and location of Biopsies during repeated PIPAC and the combination of PIPAC with additional surgical procedures.ConclusionThis consensus statement aims to allow for safe and efficacious PIPAC treatment and to facilitate multi-center analyses of the results. Additional preclinical and clinical studies are needed to resolve the remaining controversies. 相似文献

IntroductionCytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has gained traction for the management of peritoneal metastases. The number of specialist units globally offering CRS/HIPEC is increasing. The aim of this survey was to assess current practices and barriers to referral for CRS/HIPEC among colorectal surgeons in Australia and New Zealand (ANZ).Materials and methodsAn online questionnaire was emailed to members of the Colorectal Surgical Society of Australia and New Zealand (CSSANZ). The survey contained 3 sections: namely; demographics, referral patterns and clinical scenarios. Questions on referral patterns included number of peritoneal metastases patients seen per year and referred to a CRS/HIPEC unit, awareness of such a unit and distance from principle place of practice. Different pathologies referred were also explored, as well as investigations performed. Barriers to referral were also surveyed.ResultsThe response rate was 28% (83/296). Twenty-five percent received CRS training. Most surgeons (95%) were aware of a CRS/HIPEC unit and had referred to one previously. Thirty-nine percent would refer all patients. Provision of good service and/or relationship with CRS/HIPEC specialist were the main reasons for referring to the nearest unit, followed by accessibility. Major factors preventing referral included extent of peritoneal disease (48%), patient characteristics and comorbidities (44%) and lack of evidence (20%). The most common pathologies referred included colorectal and appendiceal peritoneal metastases and pseudomyxoma peritonei.ConclusionColorectal specialist awareness of CRS/HIPEC units and accessibility is high. Strategies to improve referring physician/surgeon knowledge on patient selection and indications for CRS/HIPEC should be investigated and instituted to ensure all appropriate patients are referred to specialist units for discussion of suitability. 相似文献

IntroductionThe aim of this study was to assess the degree to which patient frailty is associated with both need for assistance and time required to complete the eRFA, a web-based GA tool.Materials and MethodsWe retrospectively identified patients who underwent surgery for cancer from 2015 to 2020, had a hospital length of stay ≥1 day, and completed the eRFA before surgery. Frailty was assessed using two methods: the MSK-FI (score 0–11) and the AGD (score 0–13). Time to complete the eRFA was automatically recorded by a web-based tool; assistance with eRFA completion was self-reported by the patient.ResultsIn total, 3456 patients were included (median age, 78 years). Overall, 58% of surveys were completed without assistance, 30% were completed with assistance, and 12% were completed by someone other than the patient. Younger age (median age: without assistance, 77 years; with assistance, 80 years; completed by someone else, 80 years) and lower frailty score (median AGD: 4, 6, and 8, respectively; median MSK-FI: 2, 3, and 3, respectively) were associated with independency (all p < 0.001). Higher frailty score was associated with longer time to complete the eRFA (all nonlinear association p < 0.001).ConclusionFrail patients are more likely to benefit from completion of GA to determine appropriate treatment. Given that not all cancer patients have a caregiver who can assist completing a digital questionnaire, innovative solutions are needed to help frail patients complete the eRFA without assistance. 相似文献

IntroductionIt has been shown that cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective treatment for patients suffering from peritoneal malignancies. Despite good results, there is an ongoing debate about this treatment due to perioperative morbidity.The aim of this study is to identify relevant risk factors for an unfavorable postoperative outcome after CRS and HIPEC.Materials and methodsA retrospective analysis of a prospectively recorded database of all patients undergoing CRS and HIPEC between 2013 and 2020 in the Department of Surgery of the University Hospital Dresden was performed with a special focus on certain surgical steps of multivisceral resection, one- or 2- stage CRS/HIPEC and underlying diagnosis as possible risk factors for worse postoperative course.ResultsN = 173 CRS and HIPEC procedures were performed for various diagnoses. Relevant postoperative morbidity was 24% and 30d-mortality 1.2%. Simultaneous liver resections, preoperative hypalbuminemia and 2-staged CRS/HIPEC were significant risk factors for a worse postoperative course in multivariable analysis. Assessment of the association of simultaneous anastomoses and morbidity and mortality was inconclusive.ConclusionCRS and HIPEC is a safe treatment without relevant intraoperative morbidity and mortality and acceptable postoperative outcome. One-stage CRS/HIPEC should be preferred. 相似文献

IntroductionRole of surgery in the management of de novo stage IV breast cancer (BC) remains controversial. We aimed to determine the survival benefit of primary surgery on the basis of metastatic pattern.Materials and methodsA retrospective cohort study based on the SEER database was conducted to identify patients with de novo stage IV BC diagnosed between 2010 and 2015. Patients were divided into surgery and non-surgery group, and propensity score weighting was used to balance clinicopathologic factors between groups.ResultsOf 8142 de novo stage IV BC patients, 1891 (23%) cases were managed with surgery and 6251 (77%) cases were managed without surgery. There were 3821 all-cause deaths and 3291 BC specific deaths over a median follow-up of 22 months. The weighted 3-year overall survival (OS) for the surgery group was 54.5%, compared to 47.7% (P < 0.001) for the non-surgery group. The magnitude of the survival difference with surgery was significantly correlated with metastatic patterns (Pinteraction<0.05). Significant survival improvements in surgery group compared with non-surgery group were observed in patients with bone-only metastasis (adjusted HR = 0.83, P < 0.05) or multiple metastases with bone involved (adjusted HR = 0.76, P < 0.05), whereas survival inferiority of surgery was found for patients with multiple visceral organs-only metastases (adjusted HR = 2.08, P < 0.05).ConclusionThe survival benefit offered by surgery for de novo stage IV BC varies by metastatic patterns. Decisions for primary surgery of de novo stage IV BC patients should be tailored according to metastatic pattern. 相似文献

IntroductionCytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) were reportedly safe for the elderly. However, long-term survival data in this subgroup of patients are scarce. Our aim was to evaluate the peri-operative and long-term outcomes of CRS + HIPEC in colorectal peritoneal metastases (CRC-PM) in patients ≥70 years of age.Material and methodsWe retrospectively analyzed our combined institutional databases for patients who underwent CRS + HIPEC for CRC-PM. Clinical and pathological characteristics, as well as overall survival (OS) and progression-free survival (PFS) were compared between the groups. Tumor extent was measured by the peritoneal carcinomatosis index (PCI) and completeness of cytoreduction by the CCR score. Major morbidity was defined according to Clavien-Dindo classification.ResultsThe dataset of 159 patients included 33 elderly and 126 non-elderly patients. Clinical characteristics between the groups differed only in medical comorbidities (Charlson comorbidity index 10 vs. 7, P < 0.001) and delivery of post-HIPEC adjuvant treatment (12.5% vs. 43.8%, P = 0.004). Overall PCI and CCR0 rates were similar between the groups, as were length of stay and major morbidity and mortality rates. Long-term outcomes in the elderly group were lower than those of the non-elderly (median OS: 21.8 vs. 40.5 months, P < 0.001; median PFS: 6 vs. 8 months, P = 0.02, respectively).ConclusionsCRS + HIPEC in selected elderly patients can be safe in terms of postoperative morbidity and mortality. However, despite the same surgical extents and radicality, their long-term outcomes are inferior, possibly due to under-usage of systemic chemotherapy. 相似文献

The extent of peritoneal metastases (PM) largely determines the possibility of complete or optimal cytoreductive surgery in advanced ovarian cancer. An objective scoring system to quantify the extent of PM can help clinicians to decide whether or not to embark on CRS. Therefore several scoring systems have been developed by different research teams and this review summarizes their performance in predicting a complete or optimal cytoreduction in patients with advanced ovarian cancer. A systematic search in the MEDLINE database revealed 19 articles that described a total of five main scoring systems to predict the completeness of CRS in patients with FIGO stage III-IV ovarian cancer based on the surgical exploration of the abdominal cavity; PCI, PIV, Eisenkop, Espada, and Kasper. The Peritoneal Cancer Index (PCI) and the Predictive Index Value (PIV) were mentioned most frequently and showed AUCs of 0.69–0.92 and 0.66–0.98, respectively. Due to the use of different cut-offs sensitivities and specificities greatly varied. Therefore with the current data, no scoring system could be identified as best. An objective measure of the extent of disease can be of great clinical use for identifying ovarian cancer patients for which a complete (or optimal) CRS is achievable, however due to local differences in treatment strategies and surgical policy a widely adopted objective scoring system with a standard cut-off value is not feasible. Nevertheless, objective scoring systems can play an important role to guide treatment decisions. 相似文献
