    Abstract Objective: The recent establishment of the health technology assessment (HTA) entity in the Kingdom of Saudi Arabia (KSA) has resulted in increased interest in economic evaluation. The aim of this study is to evaluate the technical approaches used in published economic evaluations and the limitations reported by the authors of the respective studies that could affect the ability to perform economic evaluations in the KSA.
    Methods: We conducted a systematic literature review of published economic evaluations performed for the KSA over the past 10 years. An electronic literature search of the PubMed, EMBASE, and Cochrane databases was performed. A CHEERS checklist was used to assess the quality of reporting. Reported limitations were classified into domains including the definition of perspectives, identification of comparators, estimation of costs and resources, and use of the incremental cost-effectiveness ratio threshold.
    Results: Twelve evaluations were identified; most involved cost-effectiveness analysis (92%). Missing and unclear data were found within the CHEERS criteria. Regardless of the perspective used, most described the perspective as an "institutional" perspective (70%) and almost half were reclassified by the current reviewer (42%). Most did not clearly state the comparator (83%), and published model comparators were commonly used (50%). Resource estimation was mostly performed by the authors of the respective studies (67%), and costs were mostly obtained from hospital institutional data (75%). The lack of an established threshold for the country-specific willingness to pay was observed in 50% of the analyses.
    Conclusions: Economic evaluations from the KSA are limited. Capacity building and country-specific HTA guidelines could improve the quality of evaluations to better inform decision making.
    Highlights: Economic analysis of health technology should follow standard guidelines. Unfortunately, these guides are often underutilized, and our findings identify considerable missing, not clearly stated, or incomplete data within the analyses, which can weaken the impact of the recommendations.The limitations reported by the authors of the respective studies emphasize the suboptimal quality of the reporting. A lack of data was frequently identified and resulted in using "institutional" practice as a major source of data input for the analyses.In light of the call for the establishment of an HTA entity in the KSA, framing a standard analytic approach when conducting economic evaluations will support HTA in informing resource allocation decisions. We hope that our findings highlight the need for country-specific guidance to improve practice and enhance future research.

    Abstract Introduction: Biliary tract cancers (BTCs), characterized by poor prognosis and limited treatment options, are increasingly prevalent malignancies with a five-year survival rate of less than 20% for advanced-stage disease. The standard first-line chemotherapy combining gemcitabine and cisplatin offers modest survival benefits, necessitating the exploration of more effective therapies. This study reports the results of a single-arm, open-label, phase 2 trial assessing the efficacy and safety of fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFIRINOX) as a first-line treatment for metastatic or locally advanced unresectable BTC.
    Methods: Patients aged ≥18 with measurable disease and adequate organ function were enrolled, receiving biweekly FOLFIRINOX for up to 12 cycles with follow-up imaging every four cycles. The primary endpoint was the overall response rate (ORR), with progression-free survival (PFS), overall survival (OS), and safety as secondary endpoints.
    Results: Thirteen patients were enrolled from December 2016 to September 2021 before early termination due to slow accrual and the emergence of immunotherapy. The ORR was 54%, with a disease control rate of 77%. Median PFS and OS were 6.8 and 19.25 months, respectively. Grade 3/4 toxicities were predominantly hematologic, with neutropenia being the most common severe adverse event.
    Conclusion: The trial suggests that FOLFIRINOX is a potentially effective first-line therapy for unresectable or metastatic BTC with a manageable safety profile. However, the early termination of the study and the introduction of immunotherapy warrant further research to confirm these findings.

    Abstract Purpose: Metastatic colorectal cancer (mCRC) is a significant global health burden. This retrospective study compared the effectiveness of trifluridine/tipiracil (FTD/TPI), regorafenib, and chemotherapy rechallenge for third-line mCRC treatment.
    Materials and methods: We reviewed the medical records of 132 patients with mCRC treated with regorafenib, FTD/TPI, or a rechallenge with the initial chemotherapy regimen in a third-line setting from four different institutions. The primary end point was progression-free survival (PFS). Secondary end points were objective response rate and overall survival (OS) across the three treatment approaches.
    Results: Twenty-nine patients received chemotherapy rechallenge, and 103 received FTD/TPI or regorafenib. Patients' characteristics were comparable, except for a lower number of left-sided primaries and
    Conclusion: This study suggests that chemotherapy rechallenge may provide a survival benefit in the third-line treatment of mCRC. However, patient characteristics, such as sex and ECOG PS, should also be considered in treatment decisions. Further prospective studies are required to confirm our findings.

    Abstract Background: Peritoneal metastasis from colorectal cancer (CRC) carries a poor prognosis in most studies. The majority of those studies used either a single-agent or doublet chemotherapy regimen in the first-line setting.
    Aim: To investigate the prognostic significance of peritoneal metastasis in a cohort of patients treated with triplet chemotherapy in the first-line setting.
    Methods: We retrospectively evaluated progression-free survival (PFS) and overall survival (OS) in 51 patients with metastatic CRC treated in a prospective clinical trial with capecitabine, oxaliplatin, irinotecan, and bevacizumab in the first-line setting according to the presence and absence of peritoneal metastasis. Furthermore, univariate and multivariate analyses for PFS and OS were performed to assess the prognostic significance of peritoneal metastasis at the multivariate level.
    Results: Fifty-one patients were treated with the above triplet therapy. Fifteen had peritoneal metastasis. The patient characteristics of both groups showed a significant difference in the sidedness of the primary tumor (left-sided primary tumor in 60% of the peritoneal group
    Conclusion: Peritoneal metastasis in patients with metastatic CRC treated with first-line triple chemotherapy does not carry prognostic significance at univariate and multivariate levels. Confirmatory larger studies are warranted.

    Abstract Background: Tyrosine kinase inhibitors remain a cornerstone in managing metastatic clear cell renal cell carcinoma (RCC). The 4 weeks on/2 weeks off intermittent sunitinib schedule could result in rebound angiogenesis and tumor progression in the 2-week rest period. We propose using bevacizumab during this period for continuous antiangiogenic effects.
    Method: This was a phase I/II study of patients with advanced clear cell RCC. Sunitinib was given 50 mg daily on a 4-week on/2-week off schedule. Bevacizumab was given on day 29 of each sunitinib cycle. The bevacizumab starting dose was 5 mg/kg, and the dose was escalated to 10 mg if there was no dose-limiting toxicity. The primary endpoints were response rate and progression-free survival (PFS).
    Results: Twenty-five patients were recruited. The study was closed prematurely because of poor accrual. No dose-limiting toxicity was observed with 5 mg bevacizumab. One patient achieved a complete response, and 12 achieved a partial response (52% response rate). At a median follow-up of 42.2 months (95%, confidence interval (CI) 32.9 to 51.4), the median PFS duration was 16.5 months (95% CI 4.1-28.8), and the median overall survival time was 33.3 months (95% CI 19.4-47.3). Twenty-two patients (88%) had at least one grade 3 or 4 toxicity; the most common were thrombocytopenia (32%), lymphopenia (32%), hypertension (28%), and fatigue (24%).
    Conclusion: Continuous angiogenesis blockade by adding bevacizumab to the sunitinib on/off regimen for advanced RCC yields significant antitumor activity with manageable increased toxicity.

    Abstract Small bowel adenocarcinoma (SBA) is an extremely rare cancer type. In the present study, the patient characteristics and clinical outcomes of patients diagnosed and treated for SBA at a single tertiary hospital were reported. All patients diagnosed and managed between 2007 and 2020 were reviewed. Regression analysis was used to assess variables associated with the metastatic stage at diagnosis. The Kaplan-Meier method was used to estimate survival and the log-rank test was used to determine factors associated with survival outcomes. Out of 137 cases of small bowel primary tumor, 43 consecutive patients with SBA were diagnosed with a median age of 53 years and the majority (76.7%) were males. The common initial presenting symptoms were abdominal pain (58.8%) and bowel obstruction (30.2%). The most common primary site was the duodenum (60.5%) and the majority (65.1%) were diagnosed with stage III/IV disease. Patients with a high neutrophil-lymphocyte ratio (NLR) (≥0.85) were more likely to be in the metastatic stage at diagnosis (P=0.01). The 3-year overall survival (OS) rates based on stage were 100% (I), 85% (II), 53% (III) and 33.9% (IV) (P=0.001). In addition to the stage, the Eastern Cooperative Oncology Group Performance Status (P<0.001), NLR (P<0.001), hypoalbuminemia (P=0.02) and chemotherapy in a metastatic setting (P=0.02) were prognostic factors for OS. In conclusion, NLR is a potential prognostic biomarker for a metastatic stage at diagnosis. Advanced stage, lower performance status score, low albumin level and high NLR are associated with short OS.
