RESUMEN

BACKGROUND/AIM: Peritoneal carcinomatosis is a sign of advanced ovarian cancer. If cytoreductive surgery results in a tumor-free situation with the remaining tumor being less than 0.25 cm, Hyperthermic intraperitoneal chemotherapy (HIPEC) may further improve prognosis. PATIENTS AND METHODS: Patients with ovarian cancer and peritoneal carcinomatosis underwent cytoreductive surgery. In 43 patients with optimal tumor debulking, HIPEC was performed. The peri- and post-operative course was observed. Adverse events were recorded after the Clavien-Dindo classification. RESULTS: The median age of the patients was 56 years, the median peritoneal cancer index (PCI) was 13, and the median operation time was 356 min. There was no postoperative surgery associated death. No adverse events were recorded in 16 (37.2%) of 43 patients, no grade III or IV adverse events were reported for 33 (76.7%) patients, and no grade IV adverse events were reported for 41 (95.3%) patients. Grade III adverse events occured in 19 (44.2%) of the 43 patients. Grade IV adverse events occured in 3 (7.0%) of the 43 patients. CONCLUSION: In ovarian cancer, multiple surgical procedures may be necessary in order to have macroscopically eradicated tumor tissue. The combination with HIPEC, further improves survival of patients with peritoneal carcinomatosis.

RESUMEN

Diffuse malignant peritoneal mesothelioma (DMPM) is a rare diagnosis, found more frequently in men than in women. Symptoms are unspecific abdominal disorders making that diagnosis difficult to set. Causes of DMPM are yet to be discovered in entirety. Asbestos exposure is the reason for approximately 7 % of all peritoneal mesotheliomas. Until the evaluation of systematic cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) DMPM was a fatal diagnosis with a median overall survival (OS) of 4-13 months. The prognosis of DMPM dramatically improved with implementation of CRS and HIPEC to an OS of 30-92 month nowadys. CRS and HIPEC were performed in this case.

RESUMEN

OBJECTIVE: To review and describe imaging findings on multidetector computed tomography in the early postoperative period after cytoreductive surgery with concomitant hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). METHODS: This was a retrospective review of consecutive patients undergoing early (≤60 days) postoperative abdominopelvic multidetector computed tomography scans after CRS + HIPEC from 2014 to 2018 at a single institution. Two radiologists separately assessed bowel wall thickening, bowel wall enhancement, bowel dilation, ascites, and pleural effusion(s) and identified any other significant finding(s). RESULTS: Thirty-two patients met the inclusion criteria. The majority of patients demonstrated bowel wall thickening (53%; n = 17) and ascites (72%; n = 23), whereas postoperative ileus (35%; n = 10), pleural effusion(s) (24%; n = 7), and bowel wall hyperenhancement (6%; n = 1) were less common. Significant findings included anastomotic leak/perforation (13%; n = 4), fistula (13%; n = 4), abscess (13%; n = 4), and bladder leak (6%; n = 2). CONCLUSIONS: Multidetector computed tomography is an excellent imaging modality to identify common postoperative findings as well as complications following CRS + HIPEC.

RESUMEN

BACKGROUND: Patients with intestinal cancer (colorectal, appendiceal, and small bowel) with peritoneal metastases (PM) have a poor prognosis. We assessed whether pressurized intraperitoneal aerosol chemotherapy (PIPAC) together with systemic chemotherapy is an effective treatment option for these entities in palliative intent. METHODS: Between November 2015 and February 2018, prospective data registry was performed (NCT03100708). Thirteen patients with intestinal cancer (median age 61 years [range 49-77]) underwent 26 PIPAC procedures with a median number of 2 interventions per patient (range 1-6). A chemoaerosol consisting of cisplatin/doxorubicin was administered during standard laparoscopy. RESULTS: The median peritoneal carcinomatosis index according to Sugarbaker before the first PIPAC was 14 (range 2-27), and the median ascites volume was 10 mL (range 0-6300 mL). Six patients who received 2 or more PIPAC procedures had decreased and stable ascites volumes, while only 1 patient displayed increased ascites. The median overall survival was 303 days (range 30-490) after the first PIPAC procedure. CONCLUSIONS: PIPAC offers a novel treatment option for patients with PM. Our data show that PIPAC is safe and well-tolerated. Ascites production can be controlled by PIPAC in patients with intestinal cancer. Further studies are required to document the significance of PIPAC within palliative therapy concepts. TRIAL REGISTRATION: NCT03100708.

RESUMEN

BACKGROUND: Approximately 70% of cancer-related deaths occur in low- and middle-income countries. In addition to social and racial inequalities, treatment options in these countries are usually limited because of the lack of trained staff and equipment, limited patient access to health services, and a small number of clinical guidelines. OBJECTIVES: The Brazilian Society of Surgical Oncology developed this guideline to address these barriers and guide physicians treating patients with endometrial cancer (EC) in regions with limited resources and few specialized centers. METHODS: The guideline was prepared from 10 January to 25 October 20192019 by a multidisciplinary team of 56 experts to discuss the main obstacles faced by EC patients in Brazil. Thirteen questions considered critical to the surgical treatment of these patients were defined. The questions were assigned to groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments for presentations in meetings, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including staging, fertility spearing treatment, genetic testing, sentinel lymph node use, surgical treatment, and other clinical relevant questions, major agreement was achieved by the participants, always using accessible alternatives. CONCLUSIONS: It is possible to provide adequate treatment for most EC patients in resource-limited areas, but the first option should be referral to specialized centers with more resources.

RESUMEN

BACKGROUND: The purpose of this study was to analyze the oncolytic and immunomodulatory functions of an M protein mutant of vesicular stomatitis virus (M51R VSV) in a murine model of peritoneal surface dissemination from colon cancer (PSD from CRC). METHODS: Luciferase-expressing CT26 peritoneal tumors were established in Balb/c mice to evaluate the impact of M51R VSV treatment on intraperitoneal tumor growth and overall survival. The mice were treated with either intraperitoneal phosphate buffered saline (n = 10) or 5 × 106 PFU M51R VSV (n = 10) at 5 d after tumor implantation. Tumor bioluminescence was measured every 3 d during the 60-day study period. The immunomodulatory effect of M51R VSV treatment was evaluated in mice treated with either intraperitoneal phosphate buffered saline (n = 21) or M51R VSV (n = 21). Peritoneal lavages were collected at days 1, 3, and 7 after M51R VSV treatment for flow cytometry and multiplex cytokine bead analysis. RESULTS: A single, intraperitoneal treatment with M51R VSV inhibited the growth of PSD from CRC as evidenced by decreased bioluminescence and improved survival. This treatment approach also resulted in significantly higher frequencies of peritoneal CD4+ T (10.95 ± 1.17 versus 6.19 ± 0.44, P = 0.004) and B1b cells (5.01 ± 0.97 versus 2.20 ± 0.2, P = 0.024). On the other hand, treatment with M51R VSV resulted in fewer myeloid-derived suppressor cells relative to controls (10.66 ± 1.48 versus 14.47 ± 1.06, P = 0.035). M51R-treated peritoneal cavities also contained lower concentrations of immunosuppressive monocyte chemoattractant protein-1 and interleukin 6 cytokines relative to controls. CONCLUSIONS: Our findings suggest that M51R VSV alters the innate and adaptive immune responses in PSD from CRC. Future studies will delineate specific components of antitumor immunity that result in its therapeutic effect.

RESUMEN

BACKGROUND: Conversion therapy is intended to allow achieving R0 resection after chemotherapy for tumors initially considered unresectable or partially resectable. Neoadjuvant intraperitoneal and systemic chemotherapy (NIPS) is the current conversion therapy for gastric cancer (GC) patients with peritoneal metastasis. This meta-analysis evaluated the effectiveness and safety of NIPS-combined surgery for GC patients with peritoneal metastasis. METHODS: Standard methods were used to select and analyze studies that included GC patients with peritoneal metastasis assigned to two groups, either NIPS-combined surgery or a NIPS-only control. Publications were retrieved from PubMed, EMBASE, Medline, and the Cochrane Central Register. Overall survival, conversion therapy success and R0 resection rates, and adverse events were analyzed using Stata 11.0. RESULTS: Eight of the 14 studies that were evaluated after screening the titles and abstracts of 327 retrieved publications met the selection criteria. The eight retrospective studies included 373 patients with GC and peritoneal metastasis included 265 with NIPS-combined surgery and 109 with NIPS only. Survival was significantly better with NIPS-combined surgery than with NIPS only (hazard ratio = 0.440, 95% confidence interval [CI]: 0.274-0.704; P = 0.0001; odds ratio = 1.960; 95% CI: 1.247-3.083; P = 0.004). Subgroup analysis revealed significantly better survival with S-1 Joint intravenous paclitaxel and intraperitoneal paclitaxel compared with other NIPS regimens. NIPS regimens had a higher conversion rate (effect size [ES] = 0.656; 95% CI: 0.495-0.817; P < 0.05), higher percentage of patients with R0 surgery (ES = 0.633; 95% CI: 0.568-0.699; P < 0.05), less severe adverse reactions to chemotherapy (ES = 0.030; 95% CI: 0.020-0.040; P < 0.05), and fewer postoperative complications (ES = 0.040; 95% CI: 0.020-0.050; P < 0.05). CONCLUSIONS: NIPS-combined surgical treatment was effective and safe for treating GC with peritoneal metastasis. Higher quality trials, better patient selection, and multicenter randomized controlled trials are needed to support standard treatment guidelines.

RESUMEN

Hyperthermic intraperitoneal chemotherapy (HIPEC) has a unique effect on the prevention and treatment of peritoneal metastasis from malignancies. Recently, the first prospective, multicenter, randomized controlled clinical trial of HIPEC to prevent the development of peritoneal metastasis after curative surgery for patients with locally advanced colon cancer was published in the "Lancet Gastroenterol Hepatol" (COLOPEC). Regrettably, no significant difference was observed in 18-month peritoneal metastasis-free survival between postoperative adjuvant HIPEC and standard systemic chemotherapy for patients with T4 stage or perforated colon cancer. However, we wonder whether we might achieve better outcomes by further optimizing the following issues: (1) We propose that the inclusion criteria for that trial may not be entirely reasonable, which included pT4N0-2M0 and perforation. Additionally, we found that 91% of patients underwent HIPEC 5-8 weeks after primary tumor resection. (2) The imbalance in starting time of postoperative systemic chemotherapy between the two groups may have a negative impact.(3) Nine patients with peritoneal metastasis preceding HIPEC might weaken the potential efficacy of HIPEC. (4) We wonder whether HIPEC using high-dese oxaliplatin (460 mg/m(2)) perfusing 30 minutes for one cycle is the optimal regimen. Therefore, we are planning to conduct a randomized controlled trial (HIPEC-06) in accordcance with the characteristics of Chinese patients, to explore the clinical efficacy of curative surgery combined with HIPEC in the treatment of cT4 colorectal cancer.

RESUMEN

The Japanese Society for Cancer of the Colon and Rectum (JSCCR) published the guidelines 2019 for the treatment of colorectal cancer in March 2019. The new edition expanded the indications of endoscopic treatment, enriched the follow-up recommendations after endoscopic resection of early colorectal cancer, supplemented the indications of ISR and added the recommendations of lymph node recurrence and peritoneal recurrence. In the new edition, the adjuvant and palliative chemotherapy schemes were revised and patients with first-line chemotherapy were divided into three categories as follows: appropriate for intensive systemic therapy (fit), inappropriate for intensive systemic therapy (vulnerable), and inappropriate for systemic therapy (frail). The new edition of guidelines can also provide references to the doctors of colorectal cancer in our country. This article intends to interpret the essentials of this new edition.

RESUMEN

OBJECTIVE: Early-phase data have demonstrated induction of antibody responses to a polyvalent vaccine conjugate (Globo-H, GM2, MUC1-TN, TF) with adjuvant OPT-821. We sought to determine if this combination decreases the hazard of progression or death compared to OPT-821 alone in patients with ovarian cancer in second/third clinical complete remission following chemotherapy. Secondary and translational objectives were overall survival (OS), safety, and immunogenicity. METHODS: From 2010-2013, patients were randomized (1:1) to receive OPT-821±vaccine-KLH conjugate subcutaneously at weeks 1, 2, 3, 7, 11, and then every 12 weeks (total 11). Dose delay or reduction was not permitted. Patients were removed for pre-defined dose-limiting toxicity. RESULTS: Of 171 patients randomized, 170 were treated. Most had disease of serous histology (85%), stage 3 disease at diagnosis (77%), and had received 2 prior regimens (68%). 32% received >6 treatment cycles [median 6, each arm (p = 0.33)]. 77% discontinued due to progression, 4% due to toxicity, and 1 due to myeloid dysplastic syndrome (MDS). Maximum toxicities included grade 4 MDS and depression/personality change (1 each, unlikely related), as well as grade 3 gastrointestinal disorders and others (n = 21, 4 related). Lesser adverse events were injection site reactions (82%) and fever (11%). Estimated HR for progression-free survival (PFS) of the vaccine + OPT-821 to OPT-821 arm was 0.98 (95% CI: 0.71-1.36). At a median follow-up of 60 months, median OS was 47 and 46 months, respectively. CONCLUSIONS: Vaccine + OPT-821 compared to OPT-821 alone was modestly immunogenic and did not prolong PFS or OS. Multi-remission patients are a viable, well-defined population for exploring innovative consolidation and maintenance approaches. TRIAL REGISTRATION: NCT00857545.

RESUMEN

BACKGROUND: Whether patients with advanced tubo-ovarian high-grade serous cancer (HGSC) fare better after upfront debulking surgery (UDS) or neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) remains controversial. METHODS: We studied patients with HGSC who underwent UDS or NACT-IDS between July 2000 and December 2015, with peritonectomy procedures combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Clinical reports were included peritoneal cancer index (PCI), NACT responses, surgical complexity score (SCS), completeness of cytoreduction (CC), complete follow-up with timing, site, and treatment of recurrence. Outcome measures were morbidity, progression-free survival (PFS), PFS2, and overall survival during a mean 5-year follow-up. RESULTS: A total of 34 patients (23.6%) underwent UDS and 110 (76.4%) NACT-IDS both combined with HIPEC. At a median 66.3-month follow-up, patients who underwent UDS or NACT-IDS had similar outcomes. NACT subgroup responses correlated with PCI, SCS, morbidity, and CC. Patients who underwent UDS had lower recurrence rates than those who responded partly or poorly to NACT (PFS, P < .04; PFS2, P < .01). Despite HIPEC, the peritoneal disease recurred in 42.5% of the overall patients. CONCLUSION: In patients with primary HGSC who undergo UDS or NACT-IDS, despite similar outcomes, peritonectomy procedures combined with HIPEC seem unable to prevent peritoneal recurrence.

RESUMEN

Objective: To analyze the efficacy and safety of cytoreduction surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP) in the early stage. Methods: The clinical data, including pathological features, recurrence and survival of 65 PMP patients in the early stage underwent CRS combined with HIPEC in Aerospace Center Hospital from January, 2011 to December, 2018 were retrospectively analyzed. Results: 65 patients with early stage PMP underwent CRS+ HIPEC. Among these patients, 25 were males and 40 were females, and the mean age was 52.5 years. The median peritoneal cancer index was 3 (0-16). The score of completeness of cytoreduction (CC) of 63 patients (96.9%) was 0, and 2 patients (3.1%) was 1. No perioperative death occurred, the incidence of surgical complications above grade 3 was 3.1%. Three patients relapsed during the follow-up period, including 1 patient with low-grade PMP, 1 patient with high-grade PMP, and 1 patient with high-grade PMP accompanied by signet ring cell. The 5-year disease-free survival rate of the whole group was 92.4%. Conclusions: PMP patients in the early stage treated by CRS combined with HIPEC can achieve benefit and safety. A close long-term follow-up is necessary.

RESUMEN

One of the main problems in the treatment of peritoneal carcinomatosis (PC) in colorectal cancer (CRC) is the adequate selection of patients for cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). AIM: To determine the predictive factors of overall (OS) and disease-free survival (DFS) in CRC patients with PC after CS with HIPEC. MATERIAL AND METHODS: From 2010 to 2018 years 102 patients with CRC and PC were included in the study. The cytoreduction was complete (CC0, according to Sugabaker scale) in 96 (94.2%) cases. The age median of patients was 65 years. There were 63 (62%) women. In 81 (79%) patients, the PC was synchronous. The median level of CEA was 8.5 ng/ml. The median peritoneal carcinomatous index (PCI) was 3 (1-23). RESULTS: The median of follow-up was 18 (11; 33) months. The median of DFS and OS were 13 (9;31) and 32 (17; n/d) months, respectively. Multifactorial Cox-regression analysis showed the localization of the primary tumor in the right colon (OR=1.66; 95% CI 1.1-2.5; p=0.013) and the level of the PCI (OR = 1.08; 95% CI 1.024-1.15; p=0.008) were independent negative factors of OS. CONCLUSION: The CS and HIPEC in patients with CRC with PC allowes to achieve five-year survival in a part of patients, especially with low PCI. Identifying adverse prognostic factors preoperatively can help in selecting patients for CS in the future.

RESUMEN

Objective: To analyze the status of domestic surgical treatment of synchronous peritoneal carcinomatosis from colorectal cancer in China. Methods: Clinicopathological data of patients who underwent surgery from October 2003 to October 2018 in 16 domestic medical centers was retrospectively analyzed. Excel database was created which covered 77 fields of 7 parts: baseline information of patients, laboratory tests, imaging tests, chemoradiotherapy information, intra-operative findings, postoperative pathology and follow-up data. The Wilcoxon rank-sum test was used for comparison of the measurement data between groups. The χ(2) test was used for comparison of the categorical data between groups. The survival curve was calculated by the Kaplan-Meier method. Results: Of the 1 003 patients, there were 575 male and 428 female patients with the age of (58.5±14.1) years (range: 18 to 92 years). In a total of 920 patients, the carcinoma of sigmoid colon was performed in 292 cases (31.8%) with the highest ratio. The proportion of patients with liver metastasis and lung metastasis were 27.9% (219/784) and 8.3% (64/769). Preoperative detection of carcino-embryonic antigen level was the most common method in China (87.74%, 880/1 003), and the positive rate was 64.5% (568/880). The correct rate of preoperative imaging tests was 40.7% (280/688). The ratio of peritoneal carcinomatosis index (PCI) scores between 0 and 10 was the highest (59.6%, 170/285). Two hundred and sixty-two (27.0%) patients were performed by totally laparoscopic operation in 971 patients. The resection of primary tumor was performed in 588 of the 817 patients (72.0%). In a total of 457 cases, 253 (55.4%) patients were performed cytoreduction which group scored completeness of cytoreduction (CCR) 0. The postoperative hyperthermic intraperitoneal chemotherapy was implemented in 70 of the 334 cases (21.0%). Among 1 003 cases, 562 cases (56.03%) had complete follow-up data and the median overall survival was 15 months. The primary tumor resection and the CCR scores were affected by the PCI scores. The patients underwent primary tumor resection (187/205 vs. 26/80, χ(2)=105.085, P=0.000) and the patients were performed cytoreduction which scored CCR 0 or CCR 1 (162/204 vs. 8/78, Z=-10.465, P=0.000) had significant difference between the groups of PCI<20 and ≥20. There was a close correlation between the surgical method and the CCR scores (Z=-3.246,P=0.001).When the maximum degree of tumor reduction was planned, most surgeons would choose laparotomy. The overall survival time was longer in patients with primary tumor resection (P=0.000). The median survival time was 18.6 months in the group of primary tumor resection. Conclusions: It is difficult to diagnose the synchronous peritoneal carcinomatosis from colorectal cancer before the operation. Primary tumor resection has an obvious effect to prolong the survival time. It is necessary to standardize the treatment of peritoneal metastasis.

RESUMEN

BACKGROUND: Colorectal cancer is the second leading cause of cancer-related mortality worldwide. Peritoneal metastases carry the worst prognosis among all sites of colorectal cancer metastases. In recent years, the advent and acceptance of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have greatly improved survival for selected patients with low-volume peritoneal metastases. OBJECTIVE: Here, we report the evolution of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases at a statewide tertiary referral center over an 8-year period. DESIGN: This is a retrospective study from 2009 to 2017. SETTING: The study was conducted at a single center over 8 years. PATIENTS: Patients with colorectal peritoneal metastases undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were included. MAIN OUTCOMES: Main outcomes included evaluation of grade III/IV morbidity rate, mortality rate, overall and relapse-free survival, and prognostic factors influencing survival on a Cox multivariate analysis model. RESULTS: One hundred one cytoreductive surgeries were undertaken on 96 patients during this time for colorectal peritoneal metastases. The median patient age was 60 years with 55.2% being female. The median Peritoneal Carcinomatosis Index was 9, with complete cytoreduction achieved in 76 (75.2%) cases. Grade III or IV complications occurred in 26 cases (25.7%) with 2 (2%) perioperative mortalities. Median overall survival for the entire cohort was 32 months, with a 3-year survival of 38%. For patients who achieved a complete cytoreduction, median overall survival was 37 months, with a relapse-free survival of 13 months and a 3-year survival of 54%. Complete cytoreduction and nonmucinous histology were key factors independently associated with improved overall survival. LIMITATIONS: The main limitation this study is its retrospective nature. CONCLUSION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for isolated low-volume colorectal peritoneal metastases is safe and effective, with low morbidity. It offers selected patients a highly favorable overall and relapse-free survival. See Video Abstract at http://links.lww.com/DCR/B2. EVOLUCIÓN DE LA CIRUGÍA CITORREDUCTIVA Y QUIMIOTERAPIA INTRAPERITONEAL HIPERTÉRMICA (HIPEC) PARA METÁSTASIS PERITONEALES COLORRECTALES: EXPERIENCIA INSTITUCIONAL DE 8 AÑOS: El cáncer colorrectal es la segunda causa de mortalidad relacionada con el cáncer en todo el mundo. Las metástasis peritoneales tienen el peor pronóstico entre todos los sitios de metástasis del cáncer colorrectal. En los últimos años, el advenimiento y la aceptación de la cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica ha mejorado enormemente la supervivencia de pacientes seleccionados con metástasis peritoneales de bajo volumen. OBJETIVO: Aquí, informamos sobre la evolución de la cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica para las metástasis peritoneales colorrectales en un centro de referencia terciario para todo el estado durante un período de ocho años. DISEÑO:: Estudio retrospectivo del 2009 a 2017. CONFIGURACIÓN:: Centro único a lo largo de ocho años. PACIENTES: Pacientes con metástasis peritoneales colorrectales sometidos a cirugía citorreductiva y quimioterapia intraperitoneal hipertérmica. RESULTADOS PRINCIPALES: Los resultados principales incluyeron la evaluación de la tasa de morbilidad de grado III / IV, la tasa de mortalidad, la supervivencia general y libre de recaída y los factores pronósticos que influyen en la supervivencia en el modelo de análisis multivariado Cox. RESULTADOS: Se realizaron el ciento uno cirugías citorreductivas en noventa y seis pacientes durante este tiempo por metástasis peritoneales colorrectales. La edad media de los pacientes fue de 60 años, con un 55.2% de mujeres. El Índice de Carcinomatosis Peritoneal mediano fue de 9, con una citorreducción completa lograda en 76 (75.2%) casos. Las complicaciones de grado III o IV ocurrieron en 26 casos (25.7%) con dos (2%) de mortalidad perioperatoria. La supervivencia mediana general para toda la cohorte fue de 32 meses, con una supervivencia de 3 años del 38%. Para los pacientes que lograron una citorreducción completa, la supervivencia global media fue de 37 meses, con una supervivencia sin recaída de 13 meses y una supervivencia de 3 años del 54%. La citorreducción completa y la histología no mucinosa fueron factores clave asociados de forma independiente con una mejor supervivencia general. LIMITACIONES: La principal limitación es la naturaleza retrospectiva del estudio. CONCLUSIÓN:: La cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica para las metástasis peritoneales colorrectales aisladas de bajo volumen son seguras y eficaces, con baja morbilidad. Ofrece a los pacientes seleccionados una supervivencia global altamente favorable y libre de recaída. Vea el Resumen del video en http://links.lww.com/DCR/B2.

RESUMEN

INTRODUCTION: Cytoreduction Surgery with Hyperthermic Intraperitoneal Chemotherapy (CRS/HIPEC) is a treatment option for patients with peritoneal metastatic cancer. This procedure has been shown to improve survival, however, patients are often left with abdominal wall and soft tissue defects requiring further surgical correction. We aim to assess the safety and clinical outcomes of abdominal reconstruction performed concurrent with CRS/HIPEC. METHODS: We conducted a retrospective chart review on patients with peritoneal metastases who received CRS/HIPEC therapy and abdominal wall reconstruction at tertiary center from 2012 to 2018. Records were evaluated for the patient characteristics, oncologic history, operative details, and postoperative course. Complications were graded with the Clavien-Dindo classification. RESULTS: Five patients aged 29-54 years old met the inclusion criteria. The most common type of cancer within this cohort was colorectal cancer. To close the abdomen, four patients underwent component release, biologic mesh placement, and primary fascial closure. The last patient was closed with adjacent tissue transfer. Two patients experienced Grade I complications: deep vein thrombosis and leukocytosis (both self-resolved). Three patients experienced Grade II complications: atrial fibrillation, anemia, and a wound infection which required readmission. No patients experienced grades III, IV or V complications. The follow up period was a median of 5.3 months [r: 2.6-21.9 months]. CONCLUSION: The patients benefitted therapeutically from combined abdominal reconstruction and CRS/HIPEC with minimal complications and good long-term survival. We advocate for the coupling of these procedures as the benefits outweigh the risks, and allows wound closure at the time of surgery.

RESUMEN

INTRODUCTION: Precise definitions of recurrences and optimal treatment strategy are yet to be clearly defined among patients with cervical cancer (CC). The purpose of this study was to develop a reproducible classification of CC recurrence. MATERIEL AND METHODS: Data of women with FIGO stages I-IV CC treated between January 2000 and January 2015 were retrospectively abstracted from nine French institutions. We proposed a rTNM classification for recurrence: locoregional (rT), nodal (rN), or distant organ (rM). According to rTNM prognosis, we then defined a rSTAGE classification (I, II, IIIA, IIIB, IVA, IVB). RESULTS: Among the 1028 women treated for FIGO stages I-IV CC during the study period, 216 recurrences were observed (21%). The 3-year survival after recurrence was 38.8%, with a median time to recurrence of 9 months (95% CI, 30.9-48.7). A trend for a lower 3-year survival after recurrence was observed in women with multiple-site vs single-site recurrence (p = 0.1). Among the women in the rT group, a difference in 3-year survival after recurrence was found between rT1 single site, rT2 single site and rT3 single site (p = 0.02). The 3-year survival after recurrence was 69.1%, 49.2%, 37.5%, 34.2%, 23.1% and 24.4% for rStage I, II, IIIA, IIIB, IVA and IVB, respectively (p = 0.007). CONCLUSION: rTNM classifications and rSTAGE are discriminatory and allow all recurrence modalities to be classified.

RESUMEN

BACKGROUND: Twenty to thirty percent of planned cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC) procedures are abandoned intra-operatively. Pre-operative factors associated with unresectability identified previously were used to develop a Pre-Operative Predictive Score (PROPS), which was compared with current selection criteria-Peritoneal Surface Disease Severity Score (PSDSS), Verwaal's Prognostic Score (PS) and Colorectal Peritoneal Metastases Prognostic Surgical Score (COMPASS), to determine which score provides the best prediction for unresectability. METHODS: Fifty-six patients with peritoneal metastases of colorectal origin were included. Beta-coefficient values of significant variables (p < 0.05) were determined from multivariate analysis to develop PROPS. PROPS, PSDSS, PS and COMPASS were compared using a receiver operating characteristic curve to calculate its accuracy, sensitivity and specificity. RESULTS: PROPS consisted of nine patient and tumour factors which were categorised into three groups: (i) poor tumour biology: previous inadequate resection, underwent multiple lines of chemotherapy and poorly differentiated or signet cell histology; (ii) heavy tumour burden: abdominal distension, palpable abdominal mass and computed tomography findings of ascites, small bowel disease and/or omental thickening; and (iii) active tumour proliferation: elevated tumour markers. Overall, PROPS achieved 86% accuracy with 100% sensitivity and 68% specificity, PSDSS achieved 85% accuracy with 100% sensitivity and 63% specificity, PS achieved 73% accuracy with 100% sensitivity and 68% specificity and COMPASS achieved 61% accuracy with 27% sensitivity and 100% specificity. CONCLUSIONS: PROPS is more effective in predicting unresectability as compared to PSDSS, PS and COMPASS, and has the added advantage of using solely pre-operative factors.

RESUMEN

BACKGROUND: Peritoneal surface malignancy (PSM) was historically associated with a poor survival. The adoption of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) can now offer patients with PSM a favourable overall survival. Here, we report our single-institute outcomes following CRS and HIPEC for PSM and evaluate changes in our practice over time. METHODS: This is a retrospective review from 2009 to 2018 of all patients undergoing CRS and HIPEC for PSM at a statewide peritoneal disease centre. Cases were divided into the first half and second to compare changes in practice over time. RESULTS: Three hundred and eighty four CRS and HIPEC cases were performed during this time. The median age was 56 years with 59.6% female. The median peritoneal carcinomatosis index (PCI) was 11, with a reduction in PCI in the second cohort (9 v 15, p < 0.01). Complete cytoreduction rates were significantly higher in the second cohort (82.3% v 67.7%, p < 0.01). Overall, grade III/IV complications occurred in 101 cases (26.3%) with three (0.8%) perioperative mortalities. Median overall survival (OS) for the entire cohort was 85 months, with a 5-year survival of 52%. Median OS was 97 months for PMP, 34 months for colorectal peritoneal metastases and 27 months for other histologies. Completeness of cytoreduction, histology type, and PCI were factors independently associated with overall survival. CONCLUSION: CRS and HIPEC can offer highly favourable outcomes for PSM with low morbidity. Successful complete cytoreduction rates improved significantly with greater experience and better patient selection.
