RESUMO
INTRODUCTION: The safety and efficacy of CRS + HIPEC combined with urinary tract resection and reconstruction are controversial. This study aims to summarize the clinicopathological features and to evaluate the safety and survival prognosis of CRS + HIPEC combined with urinary tract resection and reconstruction. METHODS: The patients who underwent urinary tract resection and reconstruction as part of CRS surgery were retrospectively selected from our disease-specific database for analysis. The clinicopathological characteristics, treatment-related variables, perioperative adverse events (AEs), and survival outcomes were studied using a descriptive approach and the K-M analysis with log-rank comparison. RESULTS: Forty-nine patients were enrolled. Perioperative serious AEs (SAEs) were observed in 11 patients (22.4%), with urinary SAEs occurring in 3 patients (6.1%). Additionally, there were 23 cases (46.8%) involving urinary adverse events (UAEs). The median overall survival (OS) in the entire cohort was 59.2 (95%CI: 42.1-76.4) months. The median OS of the UAE group and No-UAE group were 59.2 months (95%CI not reached), and 50.5 (95%CI: 11.5 to 89.6) months, respectively, with no significant difference (P = 0.475). Furthermore, there were no significant differences in OS based on the grade of UAEs or the number of UAEs (P = 0.562 and P = 0.622, respectively). CONCLUSION: The combination of CRS + HIPEC with urinary tract resection and reconstruction is associated with a high incidence of Grade I-II UAEs, which do not have an impact on OS. The safety profile of this combined technique is acceptable. However, this is a retrospective single-center single-arm analysis, with limitations of generalizability and potential selection bias. The findings need high-level validation.

Hyperthermic intraperitoneal chemotherapy (HIPEC) has been proven to improve the survival rate of gastric cancer and reduce peritoneal recurrence. We aimed to evaluate the effectiveness and safety of prophylactic HIPEC after radical gastric cancer surgery in this study. Researchers searched for studies published in PubMed, Embase, Web of science, Scopus, Cochrane, Clinical key databases and Microsoft Academic databases to identify studies that examine the impact of prophylactic HIPEC on the survival, recurrence and adverse events of patients undergoing radical gastric cancer surgery. RevMan 5.3 was used to analyze the results and risk of bias. The PROSERO registration number is CRD42021262016. This meta-analysis included 22 studies with a total of 2097 patients, 12 of which are RCTs. The results showed that the 1-, 3- and 5-year overall survival rate was significantly favorable to HIPEC (OR 5.10, 2.07, 1.96 respectively). Compared with the control group, the overall recurrence rate and peritoneal recurrence rate of the HIPEC group were significantly lower (OR 0.41, 0.24 respectively). Significantly favorable to the control group in terms of renal dysfunction and pulmonary dysfunction complications (OR 2.44, 6.03 respectively). Regarding the causes of death due to postoperative recurrence: liver recurrence, lymph node and local recurrence and peritoneal recurrence, the overall effect is not significantly different (OR 0.81, 1.19, 0.37 respectively). 1-, 3- and 5-year overall survival follow-up may be incremented by the prophylactic HIPEC, and which reduce the overall recurrence rate and peritoneal recurrence rate. HIPEC may have high-risk of pulmonary dysfunction and renal dysfunction complications. No difference has been found in the deaths due to recurrence after surgery.

INTRODUCTION: Hyperthermic intraperitoneal chemotherapy (HIPEC) during cytoreductive surgery (CRS) is typically reserved for a complete or optimal cytoreduction. There is the potential for therapeutic effect of HIPEC with an incomplete cytoreduction, particularly for near optimal cytoreductions. METHODS: Retrospective review of incomplete cytoreductions (R2b, R2c) for appendiceal and colorectal primaries. Primary endpoints were overall survival (OS) and progression-free survival (PFS). Subgroup analysis for primary etiology and specific cytoreductive score. RESULTS: A total of 121 cases of incomplete CRS, 74 CRS alone, and 47 CRS-HIPEC. For the entire study group there was a survival benefit with HIPEC. OS and PFS were 2.3 versus 1.4 (p = 0.001) and 1.6 versus 0.7 (p < 0.0001) respectively for cases with and without HIPEC. Subgroup analysis of appendiceal neoplasms, 43 CRS-HIPEC and 50 CRS alone, found HIPEC benefit persisted; OS and PFS were 2.4 versus 1.5 (p = 0.016) and 1.7 versus 0.8 (p < 0.0001), respectively for cases with and without HIPEC. Benefit most pronounced in low-grade cases with doubling of the OS and PFS (p = 0.004). With colorectal primary cases, 10 CRS-HIPEC and 18 CRS alone, no difference in OS and PFS. When stratifying out by cytoreduction scores, R2b and R2c, HIPEC only provided a benefit for R2b cases; OS and PFS for R2b cases were 2.28 versus 1.01 (p = 0.011) and 1.67 versus 0.75 (p = 0.001), respectively for cases with and without HIPEC. CONCLUSION: HIPEC has utility for incomplete cytoreductions with appendiceal neoplasms, greatest effect with low-grade appendiceal neoplasms. HIPEC is only beneficial for near optimal cytoreductions (R2b).

BACKGROUND AND OBJECTIVES: Locoregional metastases are typical biological manifestations of advanced malignant melanomas. Treatment with hyperthermic isolated limb perfusion (HILP) should be considered in affected patients. In the present study, we have analyzed the results of HILPs performed in our department. PATIENTS AND METHODS: Eighty patients with locoregional metastases of the extremities received HILP at the Department of Surgery between January 2007 and December 2016. The mean follow-up was 38 months. RESULTS: The study included 50 men and 30 women (mean age: 63 years). The median time between melanoma diagnosis and HILP was 25 months (range: 1-219 months). HILP was performed in curative (n = 45) and palliative (n = 35) intention. Seventy-five patients received a drug combination of melphalan/dactinomycin and five patients received a drug combination of melphalan/tumor necrosis factor-alpha. Remission rates were determined in 72 of 80 patients (90%) as follows: partial response n = 28, complete response n = 25, no response n = 19. Of the 25 patients with complete response, 13 patients developed a new tumor manifestation during follow-up (locoregional recurrences n = 4; distant metastases n = 3; both n = 6). The median overall survival rate was 33 months. Tumor stage influenced the survival rate significantly (p = 0.001). Patients with complete response showed a significantly better overall survival than patients with partial or no response (p = 0.016). CONCLUSION: HILP is an effective therapeutic option in patients with locoregional metastases. This procedure carries a certain risk of side effects and adverse events but overall results in good response rates. Therefore, HILP should be offered to selected patients based on an individual discussion, considering their health status and oncological prognosis.

INTRODUCTION: Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is offered in specialist centres as a treatment for peritoneal surface tumours. Despite its demonstrated efficacy, intra-abdominal recurrence occurs in 31-57% of patients. The aim of this study is to review the early and long-term outcomes in patients who undergo repeat CRS/HIPEC. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database of patients who had undergone repeat CRS/HIPEC for appendiceal neoplasms and colorectal peritoneal metastases (CRPM) from 2003 to 2019 was performed at a single specialist centre. Data pertaining to both short term outcomes and survival were evaluated. RESULTS: Of 1259 patients who had undergone CRS/HIPEC, 84(6.7%) underwent repeat surgery: 45(53.6%) had pseudomyxoma peritonei (PMP) secondary to low grade appendiceal mucinous neoplasms (LAMN), 21(25.0%) had appendix carcinoma and 18(21.4%) had CRPM. Demographics, intra-operative findings and short-term outcomes were comparable across tumour types and between procedures. Median (95% CI) interval between procedures was 22.7(18.9-26.6) months and was comparable between tumour types. Median (95%CI) overall survival was not reached for the cohort overall or for those with PMP, but was 61.0(32.6-89.4) months for those with appendix cancer and 76.9(47.4-106.4) months for CRPM (p=<0.001). Survival was favourable in the PMP group (HR [95%CI] 0.044 [0.008-0.262]; p = 0.000) and unfavourable in the CC2-3 at index CRS procedure group (HR [95%CI] 25.612 [2.703-242.703]; p = 0.005). CONCLUSION: Our findings demonstrate that repeat cytoredutive surgery with HIPEC can result in favourable survival, especially for patients with PMP when complete cytoreduction is achieved at index operation. We recommend that detailed patient assessment is performed through an expert multidisciplinary team meeting (MDT).

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is predominantly performed and studied in academic centers. While developing CRS/HIPEC programs in nonacademic hospitals can increase accessibility, its safety and oncological efficacy remains unclear. We evaluated CRS/HIPEC outcomes in a nonacademic setting. METHODS: A single-center descriptive study was conducted using a prospective database. Data of all CRS/HIPEC attempts in peritoneal surface malignancies (PSM) patients from October 1994 to November 2019 were extracted. Surgical and survival outcomes were measured. Center experience was assessed by quartiles of cases. RESULTS: Overall, 856 patients underwent 948 CRS/HIPEC attempts: 788 (83%) completed CRS/HIPECs, 144 (15%) aborted HIPECs, and 16 (2%) complete cytoreductions (CC-0/1) without chemoperfusion. For completed CRS/HIPECs, median peritoneal cancer index was 24 (interquartile range: 10-33) and CC-0/1 rate was 88%. Major complications occurred in 23.5% with 30- and 100-day mortality of 1.0% and 2.3%, respectively. Median overall survival was 68 months (95% confidence interval [CI]: 50-86). Median progression-free survival was 37 months (95%CI: 28-46). Incomplete cytoreduction and major complication rates decreased over time, while mortality remained low and constant. CONCLUSIONS: CRS/HIPEC at a nonacademic center with advanced surgical and auxiliary services is a safe option to treat PSM with favorable surgical and oncological outcomes.

INTRODUCTION: The PERISCOPE I (Treatment of PERItoneal dissemination in Stomach Cancer patients with cytOreductive surgery and hyPErthermic intraperitoneal chemotherapy) study was conducted to investigate the safety and feasibility of hyperthermic intraperitoneal chemotherapy (HIPEC) in gastric cancer patients with limited peritoneal dissemination. In this study, tumor characteristics and clinical outcome of the patients treated in the PERISCOPE I trial were investigated. METHODS: Patients who had undergone the full study protocol were selected; that is, preoperative systemic chemotherapy, followed by a surgical procedure consisting of a (sub)total gastrectomy, cytoreductive surgery, and HIPEC with oxaliplatin (460 mg/m2 ) and docetaxel (in escalating doses). RESULTS: Twenty-five PERISCOPE I patients underwent the full study protocol. Most patients had an ypT3-4 tumor (96%) and the diffuse-type histology was predominant (64%). Seven patients (28%) had a microscopically irradical (R1) resection. In all patients, a complete cytoreduction was achieved. Median follow-up was 37 (95% confidence interval [CI]: 34-39) months. Disease recurrence was detected in 17 patients (68%). Median disease-free and overall survival were 12 and 15 months, respectively. CONCLUSION: In this series of gastric cancer patients with limited peritoneal dissemination who underwent HIPEC surgery, unfavorable tumor characteristics were common. Survival might be encouraging but disease recurrence was frequent. The efficacy of an HIPEC procedure in improving prognosis is currently being investigated in the PERISCOPE II trial.

BACKGROUND: This study aimed to evaluate the impact of postoperative complications on long-term survival in patients with peritoneal metastasis (PM) arising from colorectal cancer (CRC) treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: Patients with PM arising from CRC treated with CRS and HIPEC were systematically reviewed at the China National Cancer Center and Huanxing Cancer Hospital from June 2017 to June 2019. High-grade complications that occurred within 30 days were defined as grade 3 to 4 events according to the Common Terminology Criteria for Adverse Events (CTCAE) classification. Univariate and multivariable Cox regression models for overall survival were created. Predictors of high-grade postoperative complications were evaluated with univariate and multivariate logistic regression analyses. RESULTS: In all, 86 consecutive cases were included in this study. Forty-one patients (47.7%) developed postoperative complications, while 22 patients (25.6%) experienced high-grade complications. No mortality occurred during the postoperative period. The median survival of all patients was 25 months, and the estimated 3-year overall survival (OS) rate was 35.0%. In the multivariable Cox regression analysis, a high peritoneal carcinomatosis index (PCI) score (HR, 1.07, 95% CI, 1.01-1.14; P=0.015) and grade 3-4 postoperative complications (HR, 1.86, 95% CI, 1.22-3.51; P=0.044) correlated with worse overall survival. High estimated blood loss (OR, 1.01, 95% CI, 1.01-1.02; P< 0.001) was identified as an independent risk factor for developing high-grade complications. CONCLUSION: Careful patient selection, high levels of technical skill and improved perioperative management are crucial to ensure patient survival benefits after CRS+HIPEC.

BACKGROUND: Objective of this study was to assess postoperative morbidity and mortality as well as recurrence-free and overall survival in patients with thymic malignancies and pleural dissemination undergoing surgical cytoreduction and hyperthermic intrathoracic chemotherapy (HITOC). METHODS: Retrospective study between September 2008 and December 2017 with follow-up analysis in May 2018. RESULTS: A total of 29 patients (male: n = 17) with thymic malignancies and pleural spread (primary stage IVa: n = 11; pleural recurrence: n = 18) were included. Surgical cytoreduction was performed via pleurectomy/decortication (P/D; n = 11), extended P/D (n = 15), and extrapleural pneumonectomy (EPP; n = 3). These procedures resulted in 25 (86%) patients with macroscopically complete (R0/R1) resection. Intraoperative HITOC was performed for 60 minutes at 42°C either with cisplatin (100 mg/m2 body surface area [BSA] n = 8; 150 mg/m2 BSA n = 6; 175 mg/m2 BSA n = 1) or with a combination of cisplatin (175 mg/m2 BSA)/doxorubicin (65 mg; n = 14). Postoperative complications occurred in nine patients (31%). Cytoprotective therapy resulted in lower postoperative creatinine levels (p = 0.036), and there was no need for temporary dialysis in these patients. The 90-day mortality rate was 3.4%, as one patient developed multiple organ failure. While recurrence-free 5-year survival was 54%, an overall 5-year survival rate of 80.1% was observed. Survival depended on histological subtype (p = 0.01). CONCLUSION: Surgical cytoreduction with HITOC is feasible in selected patients and offers encouraging survival rates. The application of cytoprotective agents appears to be effective for the prevention of postoperative renal insufficiency.

BACKGROUND: Newly diagnosed advanced-stage ovarian cancer patients are treated with neoadjuvant chemotherapy, primary or intermediate cytoreductive surgery, and hyperthermic intraperitoneal chemotherapy (HIPEC). The aim of this study is to evaluate the optimal timing of cytoreduction plus HIPEC for advanced ovarian cancer patients. METHODS: Advanced ovarian cancer patients treated with cytoreductive surgery plus HIPEC at three different hospitals between 2005 and 2019 were subgrouped regarding their time of management with cytoreduction plus HIPEC, upfront or intermediate. We retrospectively assessed the overall survival (OS), the progression-free survival (PFS), and the disease-free survival (DFS) of these groups. RESULTS: A total of 112 ovarian cancer patients were contained. Of whom, 47 patients were in the upfront group with 24 (51.1%) to be alive, while 65 patients were included in the intermediate group with 34 (52.3%) to be alive. OS (48 vs. 30 months) and DFS (42 vs. 20 months) indicated no significant difference. Although the same median PFS was observed in both groups (10 months), a higher mean PFS was observed in the upfront group (11.9 vs. 9 months, p = 0.023). CONCLUSION: The treatment of advanced ovarian cancer patients with upfront cytoreductive surgery plus HIPEC is feasible with the same survival results. Further, larger prospective studies need to verify our results.

PURPOSE: The aim of this study is to assess for the first time, the role of regional deep hyperthermia in combination with radiotherapy and systemic therapy in patients with poor prognosis of brain metastases (GPI ≤ 2.5). METHODS: Patients with confirmed cerebral metastases and classified as GPI score ≤ 2.5 were included in this prospective study. Pretreatment stratification was defined as patients with 0-1 GPI score (Group A) and patients with 1.5-2.5 GPI score (Group B). HT was applied twice a week, 60 min per session, during RT by regional capacitive device (HY-DEEP 600WM system) at 13.56 MHz radiofrequency. RESULTS: Between June 2015 and June 2017, 15 patients and a total of 49 brain metastases were included in the protocol. All patients received all HT sessions as planned. RT and systemic therapy were also completed as prescribed. Tolerance to treatment was excellent and no toxicity was registered. Patients with HT effective treatment time longer than the median (W90time > 88%) showed better actuarial PFS at 6 and 12 months (100% and 66.7%, respectively) compared to those with less HT effective treatment time (50% and 0%, respectively) (p < 0.031). Median OS was 6 months (range 1-36 months). Stratification by GPI score showed a median OS of 3 months (CI 95% 2.49-3.51) in Group A and 8.0 months (CI 95% 5.15-10.41) in Group B (p = 0.035). CONCLUSIONS: Regional hyperthermia is a feasible and safe technique to be used in combination with RT in brain metastases patients, improving PFS and survival in poor prognostic brain metastasis patients.

BACKGROUND: While parenchymal hepatic metastases were previously considered a contraindication to cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), liver resection (LR) is increasingly performed with CRS/HIPEC. METHODS: Patients from the US HIPEC Collaborative (2000-2017) with invasive appendiceal or colorectal adenocarcinoma undergoing primary, curative intent CRS/HIPEC with CC0-1 resection were included. LR was defined as a formal parenchymal resection. Primary endpoints were postoperative complications and overall survival (OS). RESULTS: A total of 658 patients were included. About 83 (15%) underwent LR of colorectal (58%) or invasive appendiceal (42%) metastases. LR patients had more complications (81% vs. 60%; p = .001), greater number of complications (2.3 vs. 1.5; p < .001) per patient and required more reoperations (22% vs. 11%; p = .007) and readmissions (39% vs. 25%; p = .014) than non-LR patients. LR patients had decreased OS (2-year OS 62% vs. 79%, p < .001), even when accounting for peritoneal carcinomatosis index and histology type. Preoperative factors associated with decreased OS on multivariable analysis in LR patients included age < 60 years (HR, 3.61; 95% CI, 1.10-11.81), colorectal histology (HR, 3.84; 95% CI, 1.69-12.65), and multiple liver tumors (HR, 3.45; 95% CI, 1.21-9.85) (all p < .05). When assigning one point for each factor, there was an incremental decrease in 2-year survival as the risk score increased from 0 to 3 (0: 100%; 1: 91%; 2: 58%; 3: 0%). CONCLUSIONS: As CRS/HIPEC + LR has become more common, we created a simple risk score to stratify patients considered for CRS/HIPEC + LR. These data aid in striking the balance between an increased perioperative complication profile with the potential for improvement in OS.

BACKGROUND: A unique time in which to effectively treat an intraabdominal malignancy is the time at which the surgeon attempts complete removal of the malignant process. Although surgery is effective for visible disease, micrometastases or multiple small cancer nodules are not amenable to resection. Alternative interventions to deal with residual disease disseminated on peritoneal surfaces are needed. MATERIALS AND METHODS: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can be combined with early postoperative intraperitoneal chemotherapy (EPIC) in order to maximally treat gross disease within the abdomen and pelvis and also the minimal residual disease that exists in many patients after resection. The third component of this treatment for ovarian malignancy was EPIC paclitaxel in this study. The clinical features, pharmacologic assessments, and survival were determined in ovarian cancer patients in whom EPIC was added to the perioperative treatment plan. RESULTS: Patients with high grade serous ovarian cancer underwent CRS, HIPEC with cisplatin/doxorubicin, and EPIC paclitaxel. These treatments combined as a single intervention were studied in 10 patients. The median number of peritonectomy procedures was 1, the median number of visceral resections was 5, and the median time required in the operating room was 8 h. Two patients had a class 3 adverse event. The median survival of patients was 50 months. Pharmacokinetic analysis of the intraperitoneal paclitaxel showed 252 ± 153 times exposure of peritoneal surfaces as compared to intravenous exposure when the drug was instilled into the peritoneal space. CONCLUSIONS: EPIC paclitaxel was successfully combined with CRS and HIPEC in 10 patients with ovarian cancer. The treatment was tolerated approximately the same as other major cytoreductive surgical procedures for ovarian cancer or other malignancies. Survival of these ovarian cancer patients seemed unusually prolonged as compared to other patients with stage 3b or recurrent disease. In this pilot study CRS, HIPEC and EPIC were safe and effective.

BACKGROUND: To investigate the clinical and pathological characteristics of appendiceal mucinous adenocarcinoma with peritoneal metastasis and analyze the prognostic factors. METHODS: A retrospective analyses of clinicopathological features of 50 patients with appendiceal mucinous adenocarcinoma with peritoneal metastasis from January, 2013 to December, 2017 in Aerospace Central Hospital, Beijing, China. Survival data calculation and comparison were respectively performed with the Kaplan-Meier method and the log-rank test. The Cox proportional hazards regression method was used for multivariate survival analyses. RESULTS: Cytoreduction for appendiceal mucinous adenocarcinoma was conducted on 50 patients (24 males and 26 females), with a median age of 52.5 years at the time of surgery (range 31-71 years). The median overall survival (OS) time was 24 months, with 2-,3- and 5-year survival rates of 53, 24 and 8%, respectively. At the last follow-up in December 2018, 13 patients were still alive. Multivariate analysis revealed that patients who had low Ki-67 expression (less than 50%) and CCR (completeness of cytoreduction) 0/1/2 score had significantly better OS rate than their respective counterparts. CONCLUSIONS: Ki-67 expression statue and CCR score could be employed as the prognosis prediction in patients with appendiceal mucinous adenocarcinoma.

BACKGROUND: Malignant and multicystic peritoneal mesotheliomas are extremely rare tumors in children, developing from mesothelial cells. No specific guidelines are available at this age. METHODS: We performed a retrospective analysis of all identified children (< 18-year-old) treated in France from 1987 to 2017 for a diffuse malignant peritoneal mesothelioma (DMPM) or a multicystic peritoneal mesothelioma (MCPM). RESULTS: Fourteen patients (5 males and nine females), aged 2.2 to 17.5 years, were included. The most frequent presenting symptoms were abdominal pain, ascitis, and alteration in the general condition. Eight patients had epithelioid mesothelioma, three had biphasic mesothelioma, and three had MCPM. Eight patients with DMPM diagnosis received cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Among them, six patients had neoadjuvant systemic chemotherapy, one patient, post-operative chemotherapy, and one patient CRS and HIPEC only. Three patients received only systemic chemotherapy. All patients with MCPM had only surgery. After a median follow-up of seven years (2-15), six patients (6/11; one death) with DMPM and two patients (two/three) with MCPM had a local and distant recurrences. CONCLUSION: Peritoneal mesothelioma in children is a rare condition with difficult diagnosis and high risk of recurrence. Worldwide interdisciplinary collaboration and networking are mandatory to help diagnosis and provide harmonious treatment guidelines.

BACKGROUND: The Prodige-7 trial has questioned the role of hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal metastases from colorectal cancer (CRC-PM). PATIENTS AND METHODS: We compared a prospectively collected group of 48 patients undergoing oxaliplatin/irinotecan-based perioperative systemic chemotherapy (s-CT) with targeted agents, and cytoreductive surgery (CRS) (no-HIPEC group) with 48 controls undergoing the same perioperative s-CT and CRS/HIPEC (HIPEC group). Patients were matched (1:1) according to the Peritoneal Surface Disease Severity Score, completeness of cytoreduction, history of extraperitoneal disease (EPD), and Peritoneal Cancer Index. RESULTS: The groups were comparable, except for a higher number of patients in the HIPEC group with World Health Organization performance status 0, pN2 stage primary tumor, and treated with preoperative s-CT. Forty-one patients in the no-HIPEC group and 43 patients in the HIPEC group had optimal comprehensive treatment (P = 0.759), defined as complete cytoreduction of PM and margin-negative EPD resection. Median follow-up was 31.6 months in the no-HIPEC group and 39.9 months in the HIPEC group. Median overall survival was 39.3 months in the no-HIPEC group and 34.8 months in the HIPEC group (P = 0.702). In the two groups, severe morbidity occurred in 14 (29.2%) and 13 (27.1%) patients, respectively (P = 1.000), with no operative deaths. On multivariate analysis, left-sided primary and curative treatment independently correlated with better survival while HIPEC did not (hazard ratio 0.73; 95% confidence interval 0.47-1.15; P = 0.178). CONCLUSIONS: Our results confirmed that, in selected patients, perioperative s-CT and surgical treatment of CRC-PM resulted in unexpectedly high survival rates. Mitomycin C-based HIPEC did not increase morbidity but did not impact prognosis.

BACKGROUND: Peritoneal recurrences from colo-rectal cancer can be isolated (PR) or associated with local recurrences (LR). The purpose of this study was to analyze patterns and outcomes of LR and PR. METHODS: Analyze from a prospective database of 108 patients treated with CCS plus HIPEC at two cancer centers between 2008 and 2015. RESULTS: The population was divided into an LPR group (presence of LR with or without PR, n = 56) and a PR group (isolated PR, n = 52). The patients characteristics (age, sex, Charlson score, PCI) or perioperative treatments were comparable between the groups. The median number of resected organs for tumor involvement (respectively, 2 vs 1; p < 0.001), the percentage of patients with metastatic lymph nodes (LN+) from the resected specimen (respectively, 25% vs 7%; p = 0.016) and the mortality rate (respectively, 9% vs 0%; p = 0.023) were significantly higher in the LPR group. After a median follow-up of 32 (1-108) months, median overall survival was comparable between the two groups (respectively, 46 vs 42 months; p = 0.262). CONCLUSIONS: LR is associated with a higher incidence of organ invasion, LN involvement (25%) and postoperative mortality. Optimal surgical resection of LR with systematic lymphadenectomy of invaded organs seems mandatory.

INTRODUCTION: Appendiceal neoplasms are uncommon tumors. Optimal treatment for patients with perforation or high-grade pathology after initial resection is unknown. This study evaluated patients with increased risk for peritoneal dissemination after primary resection, but no evidence of peritoneal disease, who underwent adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: This multi-institutional cohort study evaluated 56 patients with high-risk (HR) appendiceal neoplasms with a peritoneal carcinomatosis index of 0 who underwent HIPEC. The patients were divided into two groups: perforated low-grade appendiceal (LGA) carcinoma and HR neoplasms, which included perforated high-grade appendiceal carcinoma, positive margins after initial resection, minimal macroscopic peritoneal disease that was previously resected or completely responded to systemic chemotherapy prior to HIPEC, goblet cell carcinoma, and adenocarcinoma with signet ring cell features. Overall survival (OS) and recurrence-free survival (RFS) were estimated by Kaplan-Meier analysis. RESULTS: Thirty-eight percent of patients had perforated LGA and 68% had HR features. Five-year OS probability was 82.1% for the entire cohort, and 100% and 70.1% for patients with perforated LGA and HR features, respectively (p = 0.024). Five-year RFS probability was 79.3% for the entire cohort, and 90.0% and 72.4% for patients with perforated LGA and HR features, respectively (p = 0.025). Eight patients recurred after HIPEC and their OS was significantly worse (p < 0.001). CONCLUSION: While adjuvant HIPEC is both safe and feasible, there appears to be little benefit over close surveillance when outcomes are compared with historical and prospective studies, especially for perforated LGA carcinoma.
