RESUMEN
BACKGROUND: West Africa has among the highest rates of hepato-pancreato-biliary (HPB) malignancies in the world. Although surgery is critical for treatment, the availability of HPB surgery in Africa is unknown. This cross-sectional study investigated the current HPB surgical capacity of West African hospitals. METHOD: The Surgeons OverSeas Personnel, Infrastructure, Procedure, Equipment, and Supplies (PIPES) survey was modified to include HPB-specific parameters and quantify capacity. The survey was completed by consultant surgeons from West Africa. A PIPES index was calculated, and a higher score corresponded to greater HPB surgical capacity. RESULTS: The HPB PIPES survey was completed by 35 institutions from The Gambia, Ghana, Ivory Coast, and Nigeria. Most institutions (94.2%) were tertiary referral centres; five had an HPB-trained surgeon. The most commonly available procedure was an open cholecystectomy (91.4%), followed by gastric bypass (88.6%). Major hepatic resections (14.3%) and the Whipple procedure (17.1%) were rare. ICU capabilities were present at 88.6% of facilities while interventional radiology was present in 25.7%. CONCLUSIONS: This is the first HPB capacity assessment in Africa. This study showed the limited availability of HPB surgery in West Africa. These results can be used for regional quality improvement initiatives and as a baseline for future capacity assessments.
RESUMEN
BACKGROUND: Hepatic artery infusion (HAI) is a liver-directed therapy that delivers high-dose chemotherapy to the liver through the hepatic arterial system for colorectal liver metastases and intrahepatic cholangiocarcinoma. Utilization of HAI is rapidly expanding worldwide. OBJECTIVE AND METHODS: This review describes the conduct of HAI pump implantation, with focus on common technical pitfalls and their associated solutions. Perioperative identification and management of common postoperative complications is also described. RESULTS: HAI therapy is most commonly performed with the surgical implantation of a subcutaneous pump, and placement of its catheter into the hepatic arterial system for inline flow of pump chemotherapy directly to the liver. Intraoperative challenges and abnormal hepatic perfusion can arise due to aberrant anatomy, vascular disease, technical or patient factors. However, solutions to prevent or overcome technical pitfalls are present for the majority of cases. Postoperative HAI-specific complications arise in 22% to 28% of patients in the form of pump pocket (8%-18%), catheter (10%-26%), vascular (5%-10%), or biliary (2%-8%) complications. The majority of patients can be rescued from these complications with early identification and aggressive intervention to continue to deliver safe and effective HAI therapy. CONCLUSIONS: This HAI toolkit provides the HAI team a reference to manage commonly encountered HAI-specific perioperative obstacles and complications. Overcoming these challenges is critical to ensure safe and effective pump implantation and delivery of HAI therapy, and key to successful implementation of new programs and expansion of HAI to patients who may benefit from such a highly specialized treatment strategy.

BACKGROUND: Widespread implementation of HAI pump chemotherapy has been limited by logistic and feasibility concerns. Recent studies demonstrating excellent outcomes have fueled renewed enthusiasm and multiple new programs have emerged. This survey aims to identify barriers critical to establish a successful HAI program. METHODS: Using SurveyMonkey™, a 17-question survey assessing factors required for establishing a successful program was developed by 12 HAI Consortium Research Network (HCRN) surgical oncologists. Content analysis was used to code textual responses. Frequency of categories and average rank scores for each choice were calculated. RESULTS: Twenty-eight HCRN members responded to the survey. Implementation time varied, with 15 institutions requiring less than a year. Most programs (n = 17) became active in the past 5 years. Medical and surgical oncology were ranked most important for building a program (average ranking scores: 7.96 and 6.59/8). Administrative or regulatory approval was required at half of the institutions. The top 3 challenges faced when building a program were related to regulatory approval (6.65/9), device/equipment access (6.33/9), and drug (FUDR) access (6.25/9). CONCLUSION: Development of successful programs outside of historically established centers is feasible and requires a multidisciplinary team. Future collaborative efforts are critical for sustainability of safe/effective new programs.

BACKGROUND: Pancreatic metastases (PM) from renal cell carcinoma (RCC) are uncommon. We herein describe the long-term outcomes associated with pancreatectomy at two academic institutions, with a specific focus on 10-year survival. METHODS: This investigation was limited to patients undergoing pancreatectomy for PM between 2000 and 2008 at the University of Verona and Memorial Sloan Kettering Cancer Center, allowing a potential for 10 years of surveillance. The probabilities of further RCC recurrence and RCC-related death were estimated using a competing risk analysis (method of Fine and Gray) to account for patients who died of other causes during follow-up. RESULTS: The study population consisted of 69 patients, mostly with isolated metachronous PM (77%). The median interval from nephrectomy to pancreatic metastasectomy was 109 months, whereas the median post-pancreatectomy follow-up was 141 months. The 10-year cumulative incidence of new RCC recurrence was 62.7%. In the adjusted analysis, the relative risk of repeated recurrence was significantly higher in PM synchronous to the primary RCC (sHR = 1.27) and in patients receiving extended pancreatectomy (sHR = 3.05). The 10-year cumulative incidence of disease-specific death was 25.5%. The only variable with an influence on disease-specific death was the recurrence-free interval following metastasectomy (sHR = 0.98). In patients with repeated recurrence, the 10-year cumulative incidence of RCC-related death was 35.4%. CONCLUSION: In a selected group of patients followed for a median of 141 months and mostly with isolated metachronous PM, resection was associated with a high possibility of long-term disease control in surgically fit patients with metastases confined to the pancreas.

BACKGROUND: Hepatic artery infusion (HAI) chemotherapy is associated with overall survival (OS) in patients with resected colon cancer liver metastases (CLM). The prognostic impact of primary tumor location in CLM following hepatic resection in patients receiving regional HAI is unknown. This study seeks to investigate the prognostic impact of HAI in relation to laterality in this patient population. METHODS: Consecutive patients with resected CLM, with known primary tumor site treated with and without HAI, were reviewed from a prospective institutional database. Correlations between HAI, laterality, other clinicopathological factors, and survival were analyzed, and Cox proportional hazard regression was used to determine whether laterality was an independent prognostic factor. RESULTS: From 1993 to 2012, 487 patients [182 with right colon cancer (RCC), 305 with left colon cancer (LCC)] were evaluated with a median follow-up of 6.5 years. Fifty-seven percent (n = 275) received adjuvant HAI. Patients with RCC had inferior 5-year OS compared with LCC (56% vs. 67%, P = 0.01). HAI was associated with improved 5-year OS in both RCC (68% vs. 45%; P < 0.01) and LCC (73% vs. 55%; P < 0.01). On multivariable analysis, HAI remained associated with improved OS (HR 0.52; 95% CI 0.39-0.70; P < 0.01) but primary tumor site did not (HR 0.83; 95% CI 0.63-1.11; P = 0.21). Additional significant prognostic factors on multivariable analysis included age, number of tumors, node-positive primary, positive margins, RAS mutation, two-stage hepatectomy, and extrahepatic disease. Cox proportional hazard regression determined no significant interaction between HAI and laterality on OS [parameter estimate (SEM), 0.12 (0.28); P = 0.67]. CONCLUSIONS: Our data show an association of adjuvant HAI and increased OS in patients who underwent curative hepatectomy, irrespective of primary tumor location. Laterality should therefore not impact decision-making when offering adjuvant HAI.

Background and Objectives: To compare ablation zone involution following microwave ablation (MWA) or irreversible electroporation (IRE) of liver tumors. Materials and Methods: MWA or IRE performed for colorectal cancer liver metastasis (CRLM) or hepatocellular carcinoma (HCC) during January 2011 to December 2015 were analyzed. Patients with a tumoral response on 1-year follow-up computed tomography (CT) were included. Generalized estimating equations were used to evaluate the differences between the two modalities on ablation zone involution observed on CT at 6 (M6) and 12 months (M12), and on laboratory values (total bilirubin, alanine transaminase, aspartate transaminase, alkaline phosphatase, albumin, and platelets count). The likelihood ratio test was used to assess whether the association between ablation modalities and these outcomes differed over time. Results: Seventeen (17/44, 39%) women and 27 (27/44, 61%) men were included, with 25 HCC (25/44, 57%) and 19 CRLM (19/44, 43%) patients. IRE was used in 9 (9/19, 47%) CRLM and 5 (5/25, 20%) HCC patients, respectively. All other patients had MWA. Ablation zone size and involution between IRE and MWA differed significantly over time (interaction p < 0.01), with a mean of 241.04 vs. 771.08 mm2 (ratio 0.313; 95% CI, 0.165-0.592; p < 0.01) at M6 and 60.47 vs. 589.43 mm2 (ratio 0.103; 95% CI, 0.029-0.365; p < 0.01) at M12. Changes in liver enzymes did not differ significantly between IRE and MWA at both timepoints. Conclusions: Liver tumors treated with IRE underwent faster involution when compared to tumors treated with MWA, but liver enzymes levels were comparable.

LESSONS LEARNED: The fibrolamellar carcinoma-associated DNAJB1-PRKACA gene fusion transcript RNA codes for the catalytic domain of protein kinase A and, thus, overexpression of Aurora kinase A. ENMD-2076 showed a favorable toxicity profile. The limited results, one patient (3%) with a partial response and 57% of patients with stable disease, do not support further evaluation of ENMD-2076 as single agent. Future studies will depend on the simultaneous targeting approach of DNAJB1-PRKACA and the critical downstream components. BACKGROUND: Fibrolamellar carcinoma (FLC) represents approximately 0.85% of liver cancers. The associated DNAJB1-PRKACA gene fusion transcript RNA codes for the catalytic domain of protein kinase A and overexpression of Aurora kinase A (AURKA). ENMD-2076 is a selective anti-AURKA inhibitor. METHODS: Patients aged >12 years with pathologically confirmed incurable FLC, with measurable disease, Eastern Cooperative Oncology Group performance status 0-2 or Lansky 70-100, and adequate organ function were eligible. Patients were prescribed ENMD-2076 based on body surface area. The primary endpoint was overall objective response rate by RECIST v1.1, with a null hypothesis of true response rate of 2% versus one-sided alternative of 15%. Secondary endpoints included 6-month progression-free survival (PFS) rate (Fig. 1), median PFS, time to progression (TTP), and overall survival (OS). Safety was evaluated throughout the study. RESULTS: Of 35 patients who enrolled and received treatment, 1 (3%) had a partial response (PR) and 20 (57%) had stable disease (SD). Median TTP, PFS, and OS were 5, 3.9, and 19 months, respectively. The most frequently reported drug-related serious adverse event was hypertension in three patients. Three deaths were reported on-study-two due to disease progression and one due to pulmonary embolism not related to ENMD-2076. CONCLUSION: The study provided no rationale for further studying ENMD-2076 as a single agent in FLC.

BACKGROUND: Low central venous pressure (LCVP) anesthesia reduces blood loss during hepatic resection and historically has required a central venous catheter (CVC) for intra-operative monitoring. The aim of this study was to assess the effect of an evolution of practice to CVP monitoring without CVC on the perioperative outcomes after liver resection. METHODS: A retrospective study of partial hepatectomy patients from 2007 to 2016 who were over 18 years of age was performed. RESULTS: Of 3903 patients having partial hepatectomy, 2445 (62%) met inclusion criteria, and 404 (16%) had a CVC. Overall morbidity (33% non-CVC vs 38% CVC P = 0.076), major morbidity (16% vs 20% P = 0.067), and infective complications (superficial wound infection) 3% vs 4% P = 0.429; deep wound infection (5% vs 6% P = 0.720) did not differ between the two groups. In multivariate analysis, superficial wound infection, deep wound infection, and major complications were not associated with the presence of a CVC. All-cause mortality at 90 days was associated with CVC presence (OR 3.45, CI 1.74-6.85, P = 0.001) and age (OR 1.05, CI 1.02-1.08, P < 0.001). CONCLUSION: Since the adoption of non-invasive CVP monitoring, there has been no increase in adverse peri-operative outcomes.

OBJECTIVE: Robotic liver surgery (RLS) has emerged as a feasible alternative to laparoscopic or open resections with comparable perioperative outcomes. Little is known about the oncologic adequacy of RLS. The purpose of this study was to investigate the long-term oncologic outcomes for patients undergoing RLS for primary hepatobiliary malignancies. METHODS: We performed an international, multicenter, retrospective study of patients who underwent RLS for hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), or gallbladder cancer (GBC) between 2006 and 2016. Age, gender, histology, resection margin status, extent of surgical resection, disease-free survival (DFS), and overall survival (OS) were retrospectively collected and analyzed. RESULTS: Of the 61 included patients, 34 (56%) had RLS performed for HCC, 16 (26%) for CC, and 11 (18%) for GBC. The majority of resections were nonanatomical or segmental resections (39.3%), followed by central hepatectomy (18%), left-lateral sectionectomy (14.8%), left hepatectomy (13.1%), right hepatectomy (13.1%), and right posterior segmentectomy (1.6%). R0 resection was achieved in 94% of HCC, 68% of CC, and 81.8% of GBC patients. Median hospital stay was 5 days, and conversion to open surgery was needed in seven patients (11.5%). Grade III-IV Dindo-Clavien complications occurred in seven patients with no perioperative mortality. Median follow-up was 75 months (95% confidence interval 36-113), and 5-year OS and DFS were 56 and 38%, respectively. When stratified by tumor type, 3-year OS was 90% for HCC, 65% for GBC, and 49% for CC (p = 0.01). CONCLUSIONS: RLS can be performed for primary hepatobiliary malignancies with long-term oncologic outcomes comparable to published open and laparoscopic data.

PURPOSE: To identify and compare predictors of local tumor progression (LTP)-free survival (LTPFS) after radiofrequency (RF) ablation and microwave (MW) ablation of colorectal liver metastases (CLMs). MATERIALS AND METHODS: This is a retrospective review of CLMs ablated from November 2009 to April 2015 (110 patients). Margins were measured on contrast-enhanced computed tomography (CT) 6 weeks after ablation. Clinical and technical predictors of LTPFS were assessed using a competing risk model adjusted for clustering. RESULTS: Technique effectiveness (complete ablation) was 93% (79/85) for RF ablation and 97% (58/60) for MW ablation (P = .47). The median follow-up period was significantly longer for RF ablation than for MW ablation (56 months vs. 29 months) (P < .001). There was no difference in the local tumor progression (LTP) rates between RF ablation and MW ablation (P = 0.84). Significant predictors of shorter LTPFS for RF ablation on univariate analysis were ablation margins 5 mm or smaller (P < .001) (hazard ratio [HR]: 14.6; 95% confidence interval [CI]: 5.2-40.9) and perivascular tumors (P = .021) (HR: 2.2; 95% CI: 1.1-4.3); both retained significance on multivariate analysis. Significant predictors of shorter LTPFS on univariate analysis for MW ablation were ablation margins 5 mm or smaller (P < .001) (subhazard ratio: 11.6; 95% CI: 3.1-42.7) and no history of prior liver resection (P < .013) (HR: 3.2; 95%: 1.3-7.8); both retained significance on multivariate analysis. There was no LTP for tumors ablated with margins over 10 mm (median LTPFS: not reached). Perivascular tumors were not predictive for MW ablation (P = .43). CONCLUSIONS: Regardless of the thermal ablation modality used, margins larger than 5 mm are critical for local tumor control, with no LTP noted for margins over 10 mm. Unlike RF ablation, the efficiency of MW ablation was not affected for perivascular tumors.

BACKGROUND: The role of carcinoembryonic antigen (CEA) in surveillance and follow-up of patients with colorectal cancer continues to be debated. The objective of this study was to assess the utility of postoperative CEA as a predictor of recurrence for patients with resected colorectal liver metastases (CLM). METHODS: Patients were identified from a prospectively maintained CLM database, and were studied retrospectively. Patients with extrahepatic disease or initially unresectable CLM were excluded. All patients in this study received adjuvant systemic chemotherapy after resection. RESULTS: Between 1997 and 2007, a total of 318 consecutive patients were studied, with 168 patients (53 %) experiencing recurrence within 2 years. Various postoperative CEA cutoffs were tested as independent predictors of recurrence. A postoperative CEA ≥15 ng/ml obtained the highest hazard ratio (1.87; 95 % CI 1.09-3.2; p = 0.023) and was chosen to be included in the survival analysis in the multivariate model. A postoperative CEA ≥15 ng/ml had a specificity of 96 % and positive predictive value of 82 % for recurrence. On multivariate analysis, age ≥70 years, the presence of positive lymph node at primary tumor resection, disease-free interval ≤12 months, number of lesions >1, largest lesion ≥5 cm, presence of positive margins, and postoperative CEA ≥15 ng/ml were independent predictors of recurrence within 2 years. CONCLUSION: This study demonstrates a postoperative CEA ≥15 ng/ml to be a predictive test for recurrence.

PURPOSE: To assess biliary complications after irreversible electroporation (IRE) ablation of hepatic tumors located < 1 cm from major bile ducts. MATERIALS AND METHODS: A retrospective review was conducted of all percutaneous IRE ablations of hepatic tumors within 1 cm of the common, left, or right hepatic ducts at a single institution from January 2011 to September 2012. Computed tomography imaging performed before and after treatment was examined for evidence of bile duct dilatation, stricture, or leakage. Serum bilirubin and alkaline phosphatase levels were analyzed for evidence of biliary injury. RESULTS: There were 22 hepatic metastases in 11 patients with at least one tumor within 1 cm of the common, left, or right hepatic duct that were treated with IRE ablations in 15 sessions. Median tumor size treated was 3.0 cm (mean, 2.8 cm ± 1.2, range, 1.0-4.7 cm). Laboratory values obtained after IRE were considered abnormal after four treatment sessions in three patients (bilirubin, 2.6-17.6 mg/dL; alkaline phosphatase, 130-1,035 U/L); these abnormal values were transient in two sessions. Two patients had prolonged elevation of values, and one required stent placement; both of these conditions appeared to be secondary to tumor progression rather than bile duct injury. CONCLUSIONS: This clinical experience suggests that IRE may be a treatment option for centrally located liver tumors with margins adjacent to major bile ducts where thermal ablation techniques are contraindicated. Further studies with extended follow-up periods are necessary to establish the safety profile of IRE in this setting.

Objective: Cancer is a leading global health challenge with increasing morbidity and mortality. In Nigeria, cancer leads to over 100,000 new cases and 70,000 deaths annually. In resource-constrained countries such as Nigeria, registered nurses (RNs) that provide oncology care lack specialty education in oncology nursing care. Nigerian nurses are the largest portion of the healthcare workforce and can play a key role in improving oncology care. This study aimed to assess RNs' knowledge, willingness, and ability to perform tasks related to chemotherapy administration and symptom management, assess current practices, identify available resources, and identify gaps in RNs' knowledge of oncology care. Methods: A descriptive, correlational, Institutional Review Board (IRB)-approved study was conducted using a modified Knowledge, Attitudes, and Practice questionnaire and a questionnaire adapted from the Organizational Readiness to Change Assessment. The principle investigator (PI) adopted the role as an observer to witness an accurate picture of nursing practice at Obafemi Awolowo University Teaching Hospital (OAUTH) and identify gaps in education and knowledge around oncology nursing care. A Research Electronic Data Capture database was developed using paper-formatted questionnaires that were exported to Excel for statistical analysis. Results: This study supports findings from literature highlighting that nurses working in oncology units lack specialized oncology training, which leads to gaps in knowledge and practice. Questionnaire responses and clinical observations at OAUTH support RNs' willingness to learn skills related to oncology nursing care. Nurses are self-aware that they have more to learn about how to prepare and administer chemotherapy, and 90% of nurses reported that an ongoing chemotherapy training program would be helpful at OAUTH. Conclusions: By identifying gaps in education and knowledge about oncology care and by identifying available resources, an oncology training program could be developed for nurses working in oncology units at OAUTH and other Nigerian hospitals, leading to improved oncology patient care and outcomes.
RESUMEN
BACKGROUND: Measurement and reporting of quality indicators at the hospital level has been shown to improve outcomes and support patient choice. Although there are many studies validating individual quality indicators, there has been no systematic approach to understanding what quality indicators exist for surgical oncology and no standardization for their use. The aim of this study was to review quality indicators used to assess variation in quality in surgical oncology care across hospitals or regions. It also sought to describe the aims of these studies and what, if any, feedback was offered to the analysed groups. METHODS: A literature search was performed to identify studies published between 1 January 2000 and 23 October 2023 that applied surgical quality indicators to detect variation in cancer care at the hospital or regional level. RESULTS: A total of 89 studies assessed 91 unique quality indicators that fell into the following Donabedian domains: process indicators (58; 64%); outcome indicators (26; 29%); structure indicators (6; 7%); and structure and outcome indicators (1; 1%). Purposes of evaluating variation included: identifying outliers (43; 48%); comparing centres with a benchmark (14; 16%); and supplying evidence of practice variation (29; 33%). Only 23 studies (26%) reported providing the results of their analyses back to those supplying data. CONCLUSION: Comparisons of quality in surgical oncology within and among hospitals and regions have been undertaken in high-income countries. Quality indicators tended to be process measures and reporting focused on identifying outlying hospitals. Few studies offered feedback to data suppliers.

Effective communication about cancer diagnosis and prognosis in sub-Saharan African oncology settings is often challenged by the cancer-related shame and stigma patients and families experience. Enhancing empathic communication between health care providers, including physicians and nurses, and oncology patients and their families can not only reduce cancer stigma but also improve patient engagement, treatment satisfaction, and quality of life. To reduce lung cancer stigma, we adapted an evidence-based empathic communication skills training intervention to reduce patients' experience of stigma in Nigeria and conducted a pilot study examining the feasibility and acceptability of the empathic communication skills training. Thirty health care providers, recruited from University College Hospital, Ibadan, and Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, participated in a 2.25-hour didactic and experiential training session. Participant surveys were completed before and after the training. Overall, participants reported highly favorable training evaluations, with at least 85% of health care providers agreeing or strongly agreeing to survey items assessing training relevance, novelty, clarity, and facilitator effectiveness. Self-efficacy to communicate empathically with patients increased significantly from before-training (Mean [SD] = 3.93 [0.28]) to after-training (Mean [SD] = 4.55 [0.15]; t29 = 3.51, P < .05). Significant improvements were observed in health care provider reports of empathy toward lung cancer survivors and attitude toward lung cancer care as well as significant reductions in lung cancer blame were noted. The empathic communication skills training was feasible, well received by oncology clinicians in Nigeria, and demonstrated improvements in health care provider-reported outcomes from before- to after-training.

Background: Breast cancer-related lymphedema (BCRL) is common and has significant impact on quality of life. Very little is known about BCRL in sub-Saharan Africa. Generally, BCRL has been mostly evaluated post treatment, with very limited data on the prevalence of pre-treatment BCRL at baseline. This study presents the prevalence and clinical associations of lymphedema among newly diagnosed, treatment-naive breast cancer patients in a Nigerian cohort using bioimpedance estimations. Methods: Consecutively consenting, newly diagnosed, treatment-naive breast cancer patients were assessed for upper limb lymphedema using bioimpedance measurements of the extracellular fluid and the single-frequency bioelectrical impedance analysis value at 5 kHz. Patients were classified as having lymphedema if there was >10% difference in arm measurements or if the ratios of the arm measurements were >3 SD above a normative mean generated from representative controls. Regression analysis was performed to determine clinical variables associated with lymphedema. Results: There were 154 breast cancer patients with a median age of 47 (40.0-56.8) years and a body mass index of 27 (23.5-30.9) kg/m2. The majority (70%) had stage III disease. All measurements were significantly higher in cases than controls. Using various definitions, the prevalence of lymphedema was between 11.7% and 14.3%. Various clinical variables relating to clinical stage were significantly associated with lymphedema. Conclusion: The predominance of locally advanced disease in the Nigerian setting is associated with high pre-treatment lymphedema rates. This may set the stage for higher rates in the post-operative setting. Management of lymphedema should be incorporated into the treatment planning.
RESUMEN
The safety and efficacy of hepatic artery embolization (HAE) in treating intrahepatic cholangiocarcinoma (IHC) was evaluated. Initial treatment response, local tumor progression-free survival (L-PFS), and overall survival (OS) were evaluated in 34 IHC patients treated with HAE. A univariate survival analysis and a multivariate Cox proportional hazard analysis to identify independent factors were carried out. Objective response (OR) at 1-month was 79.4%. Median OS and L-PFS from the time of HAE was 13 (CI = 95%, 7.4-18.5) and 4 months (CI = 95%, 2.09-5.9), respectively. Tumor burden < 25% and increased tumor vascularity on preprocedure imaging and surgical resection prior to embolization were associated with longer OS (p < 0.05). Multivariate logistic regression analysis demonstrated that tumor burden < 25% and hypervascular tumors were independent risk factors. Mean post-HAE hospital stay was 4 days. Grade 3 complication rate was 8.5%. In heavily treated patients with IHC, after exhausting all chemotherapy and other locoregional options, HAE as a rescue treatment option appeared to be safe with a mean OS of 13 months. Tumor burden < 25%, increased target tumor vascularity on pre-procedure imaging, and OR on 1 month follow-up images were associated with better OS. Further studies with a control group are required to confirm the effectiveness of HAE in IHC.

PURPOSE: Hepatocellular carcinoma (HCC), the fourth most common cancer in Africa, has a dismal overall survival of only 3 months like in sub-Saharan Africa. This is affected by the low gross domestic product and human development index, absence of coherent guidelines, and other factors. METHODS: An open forum for HCC-experienced health care workers from Africa and the rest of the world was held in October 2021. Participants completed a survey to help assess the real-life access to screening, diagnoses, and treatment in the North and Southern Africa (NS), East and West Africa (EW), Central Africa (C), and the rest of the world. RESULTS: Of 461 participants from all relevant subspecialties, 372 were from Africa. Most African participants provided hepatitis B vaccination and treatment for hepatitis B and C. More than half of the participants use serum alpha-fetoprotein and ultrasound for surveillance. Only 20% reported using image-guided diagnostic liver biopsy. The Barcelona Clinic Liver Cancer is the most used staging system (52%). Liver transplant is available for only 28% of NS and 3% EW. C reported a significantly lower availability of resection. Availability of local therapy ranged from 94% in NS to 62% in C. Sorafenib is the most commonly used systemic therapy (66%). Only 12.9% reported access to other medications including immune checkpoint inhibitors. Besides 42% access to regorafenib in NS, second-line treatments were not provided. CONCLUSION: Similarities and differences in the care for patients with HCC in Africa are reported. This reconfirms the major gaps in access and availability especially in C and marginally less so in EW. This is a call for concerted multidisciplinary efforts to achieve and sustain a reduction in incidence and mortality from HCC in Africa.
