RESUMO

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.

RESUMO

BACKGROUND: Women 65 years of age or older with epithelial ovarian cancer (EOC) are thought to have a worse prognosis than younger patients. However, no consensus exists concerning the best treatment for ovarian cancer in this age group. This report presents outcomes for patients treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: A prospective database of EOC patients treated with CRS/HIPEC (1998-2019) was analyzed. Perioperative variables were compared by treatment including upfront CRS/HIPEC, neoadjuvant chemotherapy plus CRS/HIPEC (NACT + CRS/HIPEC), and salvage CRS/HIPEC, and by age at surgery (< 65 and ≥ 65 years). Survival analysis was performed, and outcomes were compared. RESULTS: Of the 148 patients identified, 42 received upfront CRS/HIPEC, 48 received NACT + CRS/HIPEC, and 58 received salvage CRS/HIPEC. Each group was subdivided by age groups (< 65 and ≥ 65 years). The median overall survival (OS) after the upfront CRS/HIPEC was 69.2 months for the patients < 65 years of age versus 69.3 months for those ≥ 65 years of age. The OS after NACT + CRS/HIPEC was 26.9 months for the patients < 65 years of age versus 32.9 months for those ≥ 65 years of age, and the OS after salvage CRS/HIPEC was 45.6 months for the patients < 65 years of age versus 23.9 months for those ≥ 65 years of age. The median progression-free survival (PFS) after upfront CRS/HIPEC was 41.3 months for the patients < 65 years of age versus 45.4 months for those ≥ 65 years of age. The PFS after NACT + CRS/HIPEC was 16.2 months for the patients < 65 years of age versus 11.2 months for those ≥ 65 years of age, and the PFS after salvage CRS/HIPEC was 18.7 months for the patients < 65 years of age versus 10 months for those ≥ 65 years of age. The median follow-up period for the entire cohort was 44.6 months [95% confidence interval (CI) 34.7-60.6 months]. CONCLUSION: Age and feasibility of complete cytoreduction should be considered when treatment methods are selected for elderly patients. A carefully selected elderly population can benefit significantly from aggressive treatment methods.

RESUMO

Importance: Studies on the prognostic role of hyperthermic intraperitoneal chemotherapy (HIPEC) in pseudomyxoma peritonei (PMP) are currently not available. Objectives: To evaluate outcomes after cytoreductive surgery (CRS) and HIPEC compared with CRS alone in patients with PMP. Design, Setting, and Participants: This cohort study analyzed data from the Peritoneal Surface Oncology Group International (PSOGI) registry, including 1924 patients with histologically confirmed PMP due to an appendiceal mucinous neoplasm. Eligible patients were treated with CRS with or without HIPEC from February 1, 1993, to December 31, 2017, and had complete information on the main prognostic factors and intraperitoneal treatments. Inverse probability treatment weights based on the propensity score for HIPEC treatment containing the main prognostic factors were applied to all models to balance comparisons between the CRS-HIPEC vs CRS-alone groups in the entire series and in the following subsets: optimal cytoreduction, suboptimal cytoreduction, high- and low-grade histologic findings, and different HIPEC drug regimens. Data were analyzed from March 1 to June 1, 2018. Interventions: HIPEC including oxaliplatin plus combined fluorouracil-leucovorin, cisplatin plus mitomycin, mitomycin, and other oxaliplatin-based regimens. Main Outcomes and Measures: Overall survival, severe morbidity (determined using the National Cancer Institute Common Terminology for Adverse Events, version 3.0), return to operating room, and 30- and 90-day mortality. Differences in overall survival were compared using weighted Kaplan-Meier curves, log-rank tests, and Cox proportional hazards multivariable models. A sensitivity analysis was based on the E-value from the results of the main Cox proportional hazards model. Differences in surgical outcomes were compared using weighted multivariable logistic models. Results: Of the 1924 patients included in the analysis (997 [51.8%] men; median age, 56 [interquartile range extremes (IQRE), 45-65] years), 376 were in the CRS-alone group and 1548 in the CRS-HIPEC group. Patients with CRS alone were older (median age, 60 [IQRE, 48-70] vs 54 [IQRE, 44-63] years), had less lymph node involvement (14 [3.7%] vs 119 [7.7%]), received more preoperative systemic chemotherapy (198 [52.7%] vs 529 [34.2%]), and had higher proportions of high-grade disease (179 [47.6%] vs 492 [31.8%]) and suboptimal cytoreduction residual disease (grade 3, 175 [46.5%] vs 117 [7.6%]). HIPEC was not associated with a higher risk of worse surgical outcomes except with mitomycin, with higher odds of morbidity (1.99; 95% CI, 1.25-3.19; P = .004). HIPEC was associated with a significantly better overall survival in all subsets (adjusted hazard ratios [HRs], 0.60-0.68, with 95% CIs not crossing 1.00). The weighted 5-year overall survival was 57.8% (95% CI, 50.8%-65.7%) vs 46.2% (95% CI, 40.3%-52.8%) for CRS-HIPEC and CRS alone, respectively (weighted HR, 0.65; 95% CI, 0.50-0.83; P < .001; E-value, 2.03). Such prognostic advantage was associated with oxaliplatin plus fluorouracil-leucovorin (HR, 0.42; 95% CI, 0.19-0.93; P = .03) and cisplatin plus mitomycin (HR, 0.57; 95% CI, 0.42-0.78; P = .001) schedules. Conclusions and Relevance: In this cohort study, HIPEC was associated with better overall survival when performed after CRS in PMP, generally without adverse effects on surgical outcomes.

RESUMO

BACKGROUND: Although potentially curable with early detection and timely treatment, breast cancer (BC) and cervical cancer (CC) remain leading causes of death for Colombian women. Lack of education, complicated administrative processes, and geographic limitations hinder early cancer detection. Today, technological tools permeate the society and could assess user risk, deliver customized information, and provide care coordination. We evaluated the effectiveness of a free mobile application (mApp) to reach women, understand misconceptions, identify users at risk for BC and/or CC, and coordinate screening tests in Cali, Colombia. METHODS: The mApp was developed and advertised in four healthcare facility waiting rooms. It used educational, evaluative, and risk factor questions followed by brief explanations to assess the population's knowledge, educate on BC and/or CC, and identify users in need of screening test(s). Women who required screening were navigated and enrolled in the national cancer program. RESULTS: From August 2017 to August 2019, 1,043 women downloaded the mApp. BC misconceptions included beliefs that BC can be prevented (87%), obesity does not increase the risk of BC (49%), and deodorant causes BC (17%). CC misconceptions included that pap smears should not be performed while sexually active (64%), vaginal pain is an early sign of CC (44%), and only women contract human papilloma virus (33%). Overall, 29% (303) were identified as at risk and needed a screening test, with 32% (98) successfully screened. DISCUSSION: mApps can identify women at risk for BC and/or CC, detect barriers to early cancer detection, and help coordinate screening test(s). This technology has widespread applications and may be useful in other underserved communities.

RESUMO

Background: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) after neoadjuvant chemotherapy (NACT) showed promise as initial treatment for stage IIIC (SIII) epithelial ovarian cancer (EOC); however, stage IV (SIV) outcomes are rarely reported. We assessed our experience and outcomes treating newly diagnosed SIV EOC with NACT plus CRS/HIPEC compared to SIII patients. Methods: Advanced EOC from 2015-2018 managed with NACT (carboplatin/paclitaxel) due to unresectable disease or poor performance status followed by interval CRS/HIPEC were reviewed. Perioperative factors were assessed. Overall survival (OS) and progression-free survival (PFS) were analyzed by stage. Results: Twenty-seven FIGO stage IIIC (n = 12) and IV (n = 15) patients were reviewed. Median NACT cycles were 3 and 4, respectively. Post-NACT omental caking, ascites, and pleural effusions decreased/resolved in 91%, 91%, and 100% of SIII and 85%, 92%, and 71% of SIV. SIII/SIV median PCI was 21 and 20 obtaining 92% and 100% complete cytoreduction (≤0.25 cm), respectively. Median organ resections were 6 and 7, respectively. Grade III/IV surgical complications were 0% SIII and 23% SIV, without hospital mortality. Median time to adjuvant chemotherapy was 53 and 74 days, respectively (p=0.007). SIII OS at 1 and 2 years was 100% and 83% and 87% and 76% in SIV (p=0.269). SIII 1-year PFS was 54%; median PFS: 12 months. SIV 1- and 2- year PFS was 47% and 23%; median PFS: 12 months (p=0.944). Conclusion: Outcomes in select initially diagnosed and unresectable SIV EOC are similar to SIII after NACT plus CRS/HIPEC. SIV EOC may benefit from CRS/HIPEC, and further studies should explore this treatment approach.

RESUMO

Background: Clinical decisions in patients with peritoneal dissemination of low-grade appendiceal mucinous neoplasms (LAMN) diagnosed during pregnancy are challenging. However, their slow progression and favorable prognosis allow deferring definitive treatment until after spontaneous delivery, a reasonable period of breastfeeding, and fertility preservation. Case Presentation. Two pregnant patients were incidentally diagnosed with LAMN and extensive peritoneal spread at 20 weeks gestation and at cesarean section. Treatment with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in both cases was delayed until spontaneous delivery at term and breastfeeding in the first patient and breastfeeding and fertility preservation in the second patient. Both patients remain disease-free for over 5 years, and their children are healthy. The literature review highlights the challenges that physicians face in treating pregnant patients with stage IV appendiceal tumors. Conclusion: Pregnancy management decisions in patients with peritoneal spread from mucinous appendiceal tumor should be based on understanding the tumor biology and prognosis. Definitive treatment in pregnant patients with favorable tumors, such as LAMN, may be delayed until spontaneous delivery without compromising maternal survival.

RESUMO

BACKGROUND: The completeness of cytoreduction (CC) score, which quantifies residual tumor, is a major prognostic factor when treating appendiceal carcinomatosis with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Both CC-0 and CC-1 are considered complete cytoreductions (CC-0/1) and associated with the best outcomes. We analyzed if the CC-0/1 definition is reliable across appendiceal histopathologic subtypes. METHODS: A prospective database of CRS/HIPEC patients with appendiceal carcinomatosis from 1998 to 2019 was reviewed to identify patients with CC-0/1. Kaplan-Meier overall survival (OS) and progression-free survival (PFS) by CC-score for each histopathology were calculated. RESULTS: Overall, 297 patients had CC-0/1. Mean age was 54 ± 12 years with 67% females. Histopathologic subtypes were 45% low-grade mucinous carcinoma peritonei (LGMCP), 27% high-grade MCP (HGMCP), 20% HGMCP with signet ring cells (HGMCP-S), and 8% goblet cell adenocarcinoma (GCAC). CC-0 and CC-1 occurred in 57% and 43% of LGMCP, 65% and 35% of HGMCP, 68% and 32% of HGMCP-S, and 79% and 21% of GCAC, respectively. OS and PFS were statistically longer for CC-0 versus CC-1 in HGMCP-S (p = 0.001 and p = 0.005, respectively) and GCAC (p < 0.001 and p < 0.001), but not in LGMCP (p = 0.098 and p = 0.398) or HGMCP (p = 0.167 and p = 0.356). CONCLUSIONS: Survival outcomes for CC-0 and CC-1 after CRS/HIPEC are different for HGMCP-S and GCAC but not for LGMCP and HGMCP. In HGCMP-S and GCAC, only CC-0 should be considered a complete cytoreduction and analyzed separately from CC-1. This distinction is key to understand disease behavior, accurately address patient prognosis, and explore new treatment strategies.

RESUMO

A Gram-stain-negative, microaerophilic, non-motile, rod-shaped bacterium strain designated PMP191FT, was isolated from a human peritoneal tumour. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism formed a lineage within the family Chitinophagaceae that was distinct from members of the genus Pseudoflavitalea (95.1-95.2 % sequence similarity) and Pseudobacter ginsenosidimutans (94.4 % sequence similarity). The average nucleotide identity values between strain PMP191FT and Pseudoflavitalea rhizosphaerae T16R-265T and Pseudobacter ginsenosidimutans Gsoil 221T was 68.9 and 62.3% respectively. The only respiratory quinone of strain PMP191FT was MK-7 and the major fatty acids were iso-C15 : 0, iso-C15 : 1 G and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c). The polar lipids consisted of phosphatidylethanolamine and some unidentified amino and glycolipids. The G+C content of strain PMP191FT calculated from the genome sequence was 43.4 mol%. Based on phylogenetic, phenotypic and chemotaxonomic evidence, strain PMP191FT represents a novel species and genus for which the name Parapseudoflavitalea muciniphila gen. nov., sp. nov. is proposed. The type strain is PMP191FT (=DSM 104999T=ATCC BAA-2857T = CCUG 72691T). The phylogenetic analyses also revealed that Pseudobacter ginsenosidimutans shared over 98 % sequence similarly to members of the genus Pseudoflavitalea. However, the average nucleotide identity value between Pseudoflavitalea rhizosphaerae T16R-265T, the type species of the genus and Pseudobacter ginsenosidimutans Gsoil 221T was 86.8 %. Therefore, we also propose that Pseudobacter ginsenosidimutans be reclassified as Pseudoflavitalea ginsenosidimutans comb. nov.

RESUMO

BACKGROUND: During cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), surgeons are reluctant to perform unprotected pelvic anastomosis despite lack of supporting data. We analyzed pelvic anastomosis outcomes and factors that influence ostomy creation in CRS/HIPEC patients. METHODS: A single-center, descriptive study of patients with rectal resection during CRS/HIPEC was conducted using a prospective database. Surgical variables were reviewed. Multinomial logistic regression of outcomes (end or protective ostomy) was performed with pre- and intraoperative factors as predictors. RESULTS: Overall, 274 of 789 CRS/HIPEC patients underwent rectal resection, including 243 (89%) with pelvic anastomosis [232 (85%) without ostomy, 11 (4%) with protective ileostomy] and 31 (11%) with no anastomosis [16 (6%) with end colostomy, 15 (5%) with end ileostomy]. The median age was 57 and 29% (79) were male. Of 243 pelvic anastomosis patients, 3 (1.2%) had rectal anastomotic leaks, including 1 with a protective ileostomy. Other anastomotic leaks occurred in 3.6%. Overall, 13% had Clavien-Dindo complications ≥ IIIB and the readmission rate was 30%. Mortality at 30 days and 100 days was 0.4% and 2.2%, respectively. Male gender and primary rectal cancer were associated with protective ileostomy [odds ratio (OR) = 7.01, 95% CI: 1.6-31.5, p = 0.011, and OR = 16.4, 95% CI: 3-88.4, p = 0.001, respectively). Male gender and prior pelvic surgery were associated with end colostomy (OR = 13.9, 95% CI: 3.7-53, p < 0.0001, and OR = 17.2, 95% CI: 3.8-78.6, p < 0.0001). CONCLUSIONS: Pelvic bowel reconstruction without protective or end ostomy during CRS/HIPEC is safe. Protective ileostomy is associated with male gender and primary rectal cancer. End colostomy is associated with male gender and prior pelvic surgery.

RESUMO

BACKGROUND: Low-grade appendiceal mucinous neoplasms (LAMN) are tumors that frequently present with peritoneal spread of either acellular mucin (AM) or cellular mucin (CM). We aim to determine how mucin types and distribution affect survival. PATIENTS AND METHODS: A retrospective cohort study was conducted using a prospective database. Newly diagnosed LAMN patients with AM versus CM treated with cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) were compared. Postoperative pathology reports were reviewed to assess each involved abdominal zone. Survival was analyzed using the Kaplan-Meier method. RESULTS: Of 121 identified patients, 50 (41%) had peritoneal lesions with AM and 71 (59%) with CM. Peritoneal cancer index was lower in AM versus CM (mean: 19 ± 13 vs 28 ± 10, p = 0.004), but complete cytoreduction (CC) rates were similar (98% vs 96%, p = 0.642). The 5-year progression-free survival (PFS) was higher in AM versus CM (96% vs 69.8%, p = 0.002). CM patients had zones with both types of lesions: with and without cells. The CM subgroup analysis showed significant differences in 5-year progression-free survival (PFS) among patients with 1-3, 4-7, and 8-10 zones with cells (95.2%, 68.4%, and 35.7%, respectively, p < 0.001), but PFS was not affected by the number of zones with any lesion type. There was no difference in overall survival (OS) between groups. CONCLUSIONS: Despite comparable CC rates after CRS/HIPEC, CM patients have shorter PFS than AM patients. In CM patients, more zones with cells, but not the total number of involved zones, negatively impact PFS. Mucin type does not impact OS. It is important to assess and report mucin cellularity in LAMN specimens.

RESUMO

BACKGROUND: Despite meticulous preoperative diagnostics, aborted hyperthermic intraperitoneal chemotherapy (AHIPEC) is a common, unsuccessful outcome of curative cytoreductive surgery (CRS)/HIPEC. OBJECTIVE: The aim of this study was to evaluate the association between AHIPEC and preoperative risk factors of patients with mucinous appendiceal cancer (AC). METHODS: A single-institute, case-control study was conducted using a prospective database. Potentially resectable patients with peritoneal carcinomatosis of mucinous AC origin with AHIPEC between October 1994 and February 2019 were identified. Preoperative risk factors were reviewed. Analysis was conducted by tumor grade: low-grade, high-grade, and signet ring cell carcinoma (high-S). All available tumor-type-matched successful CRS/HIPEC controls were obtained from the same database. Univariable and multivariable analyses were performed. RESULTS: Overall, 21, 44, and 15 AHIPEC cases and 153, 133, and 53 tumor-matched controls were identified for low-grade, high-grade, and high-S populations, respectively. Multivariable analysis revealed preoperative cancer antigen (CA) 19-9 > 1 upper limit of normal (ULN) [odds ratio (OR) 6.32; p = 0.014], CA125 > 2 ULN (OR 7.02; p = 0.039), C-reactive protein (CRP) > 2.5 mg/L (OR 13.7; p = 0.001), and previous HIPEC (OR 7.5; p = 0.031) were significantly associated with AHIPEC in the low-grade population. Preoperative CRP > 2.5 mg/L (OR 7.77; p < 0.0001) and previous HIPEC (OR 4.69; p = 0.004) were associated with AHIPEC in a multivariable model for high-grade AC. No single factor showed a significant association with AHIPEC in high-S patients. CONCLUSION: Risk factors vary for AHIPEC among low-grade, high-grade, and high-S AC histology. Elevated preoperative CA19-9, CA125, CRP, and previous HIPEC should be considered in the selection process for CRS/HIPEC in low-grade AC, as well as elevated CRP and previous HIPEC in high-grade AC, to avoid unnecessary surgery.

RESUMO

BACKGROUND: Appendiceal goblet cell adenocarcinoma (GCA) is often misclassified and mistreated due to mixed histologic features. In general, cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is standard of care for peritoneal carcinomatosis (PC) from mucinous appendiceal tumors; however, in PC from GCA, data are limited and the role of CRS/HIPEC is controversial. We report outcomes in PC from appendiceal GCA treated with CRS/HIPEC. PATIENTS AND METHODS: A prospective institutional database of 391 CRS/HIPEC patients with appendiceal carcinomatosis from 1998 to 2018 was reviewed. Twenty-seven patients with GCA were identified. Perioperative variables were described. Survival was estimated using the Kaplan-Meier method. RESULTS: GCA occurred in 7% (27/391) of appendiceal CRS/HIPEC patients. Seven (26%) cases were aborted. Two patients underwent a second CRS/HIPEC for peritoneal recurrence. Median age at diagnosis was 53 years (range 39-72 years), and 12 (60%) were female. All underwent previous surgery. Seven (35%) had prior chemotherapy and received a median of 5 cycles (range 3-8). Median PCI was 6 (range 1-39). Complete cytoreduction was achieved in 95% (19/20). Grade III complications occurred in three (15%) patients, and no perioperative deaths occurred. Median follow-up was 97 months. Overall survival at 1, 3 and 5 years was 100%, 74% and 67%, respectively. Progression-free survival at 1, 3, and 5 years was 94%, 67% and 59%, respectively. CONCLUSION: CRS/HIPEC should be considered as the main treatment option for patients with PC from appendiceal GCA. When performed at a CRS/HIPEC specialty center, 5-year OS of 67% can be achieved.

RESUMO

Breast and cervical cancers are leading causes of mortality among women in Latin America. Colombia has universal health care and a government-sponsored 10-year cancer control plan focused on prevention, early detection, and treatment. However, many administrative and social barriers have hindered its success, and a majority of patients are diagnosed at a late stage. Established in 2012, Partners for Cancer Care and Prevention (PFCCAP) works to decrease the burden of these cancers by mitigating the obstacles women face during their cancer diagnosis and treatment. Through community outreach meetings with medical personnel, hospital directors, and government officials, PFCCAP identified major barriers, including lack of trained health care personnel, few centers with adequate screening equipment, and a fragmented health system with significant administrative delays and poor continuity of care. Its solution included monthly teleconferences, biannual on-site training, quality control programs, and improved access to screening equipment. PFCCAP also initiated a patient navigation project. After implementation of the PFCCAP plan of action, from 2012 to 2018, the average time from initial consult to biopsy decreased from 65 to 20 days; from biopsy to diagnosis, 33 to 4 days; and from diagnosis to surgery, 121 to 60 days. To date, more than 1,500 women have benefited from this initiative, which has expanded to other regions. Overall, PFCCAP is creating centers of excellence in strategically located hospitals and promoting the implementation of national guidelines. Although several barriers still exist, PFCCAP is helping to implement an efficient health care model that can be replicated in other underserved populations.
