The Impact of Malnutrition on the Quality of Life of Colorectal Cancer Patients in a Tertiary Hospital.

Malnutrition among colorectal cancer patients can impair quality of life and decrease survival. This study evaluated the nutritional status of colorectal cancer patients and its association with quality of life among Filipino colorectal cancer patients seen in a tertiary hospital. A cross-sectional study was conducted among colorectal cancer patients seen at the Philippine General Hospital between December 1, 2019 and February 28, 2020. Nutritional status was evaluated using the Subjective Global Assessment, while quality of life was assessed using the EORTC QLQ-C30. Descriptive statistics, ANOVA and logistic regression were employed for analysis. Among 292 patients, malnutrition was noted in 76.4%. Stage III cancer had a higher odds for malnutrition (OR (odds ratio) = 6.22, 95% confidence interval (CI): 1.59, 24.42). Patients who received or were currently receiving chemotherapy were less likely to develop malnutrition (OR = 0.35, 95% CI: 0.18-0.69). Global health status and all functional subscale scores for the severely malnourished group were lower while the scores for symptom scales increased with the degree of malnutrition. There was a high prevalence of malnutrition among colorectal cancer patients and this was associated with poor quality of life. Future directions emphasizing early nutritional screening and assessment are recommended.

Jejunocolic fistula presenting as chronic diarrhoea from advanced lymphoma.

Jejunocolic fistula, a late complication of intestinal lymphoma, is a rare entity with only five reported cases in the literature. We report a young male presenting with a left lateral neck mass 5 years ago which then progressed to superior vena cava syndrome. Despite receiving radiotherapy and two cycles of chemotherapy, there was still tumour progression. He presented with a 2-week history of diarrhoea, haematochezia and weight loss for which antibiotics provided no relief. Esophagogastroduodenoscopy and colonoscopy showed a jejunocolic fistula. After discussion with the multidisciplinary team, nutritional upbuilding was initiated followed by exploratory laparotomy with segmental resection and anastomosis. On histopathology, diffuse large B-cell lymphoma involving the jejunum and colon was noted. Despite receiving palliative chemotherapy, he still succumbed to disease progression. This case highlights the importance of early recognition of jejunocolic fistulas among patients with intestinal lymphomas to facilitate early multidisciplinary intervention.

Safe and effective treatment of venous Thromboembolism associated with Cancer: focus on direct Oral Anticoagulants in Asian patients.

Cancer-associated thrombosis (CAT) poses a significant disease burden and the incidence in Asian populations is increasing. Anticoagulation is the cornerstone of treatment, but can be challenging due to the high bleeding risk in some cancers and the high risk of recurrent venous thromboembolism (VTE) in patients with malignancies. Direct oral anticoagulants (DOACs) are well established as first-choice treatments for VTE in non-cancer patients, offering a more convenient and less invasive treatment option than low-molecular-weight heparin (LMWH). Asian patients have exhibited comparable efficacy and safety outcomes with other races in trials of DOACs for VTE in the general population. Although no specific data are available in Asian patients with CAT, results from randomized controlled trials of apixaban, edoxaban, or rivaroxaban versus the LMWH, dalteparin, indicate that DOACs are a reasonable alternative to LMWH for anticoagulation in Asian patients with CAT. This is further supported by analyses of real-world data in Asian populations demonstrating the efficacy and safety of DOACs in Asian patients with CAT. Apixaban, edoxaban, or rivaroxaban are recommended in the most recently updated international guidelines as first-line therapy for CAT in patients without gastrointestinal or genitourinary cancers and at low risk of bleeding. An increased risk of major gastrointestinal bleeding was evident with edoxaban or rivaroxaban, but not apixaban, versus dalteparin in the clinical trials, suggesting that apixaban could be a safe alternative to LMWH in patients with gastrointestinal malignancies. Determining the optimal anticoagulant therapy for patients with CAT requires careful consideration of bleeding risk, tumor type, renal function, drug-drug interactions, financial costs, and patients' needs and preferences.

Clinicopathologic Factors Associated with Mismatch Repair Status Among Filipino Patients with Young-Onset Colorectal Cancer.

INTRODUCTION: Young-onset colorectal cancer is recognized as a distinct disease that may be sporadic or hereditary in nature. Microsatellite instability testing is recommended as a routine procedure in evaluating colorectal cancer specimens, especially in young-onset disease, because of implications in management. Immunohistochemistry of mismatch repair proteins serves as an inexpensive alternative to microsatellite instability testing with the added advantage of monitoring protein expression levels that may suggest underlying genetic or epigenetic alterations. This descriptive study aimed to determine the frequencies of proficient and deficient mismatch repair status among Filipino young-onset colorectal cancer patients, and to investigate their clinicopathologic profile. METHODS: Tumor tissues were prospectively collected from patients from two tertiary hospitals in the Philippines. Patients of age ≤45 years with resected adenocarcinoma of the colon or rectum were recruited. RESULTS: Seventy-seven out of 124 patients had tumor samples sent for immunohistochemistry. Of these, 61 samples (79%) were found to have proficient status while 16 samples (21%) had deficient status. Mismatch repair protein deficiencies, when present, more commonly involved MSH2 and MSH6 (9%) rather than MLH1 and PMS2 (5%). The deficient group had a mean age of 37.1 years and a female preponderance (56.25%), presenting as locally advanced ascending or descending colon tumors with mucinous histology in half of the population. The mismatch repair proficient group presented as locally advanced rectal and sigmoid tumors but with fewer mucinous adenocarcinomas (26.2%) compared to the deficient group. In both the mismatch repair proficient and deficient patients with family history reports, most did not have any known relative with cancer (75.4% and 68.75%, respectively). CONCLUSION: This is the first attempt to perform mismatch repair testing among young-onset colorectal cancer patients in the Philippines and to gather data on their clinicopathologic characteristics. However, the limited sample size precludes conclusive results for the associations of mismatch repair with clinicopathologic features.

The role of the medical oncologist in the holistic care of patients with cancer in the Philippines.

In the past decade, cancer care in the Philippines has advanced in response to the complex heterogeneity inherent to the disease and the constantly increasing number of patients. Central to this development is the increased awareness and universal acceptance of the multidisciplinary team (MDT) approach in providing cancer care to optimize outcomes where medical oncologists play a vital role. This position paper summarizes the unique and multifaceted roles of the medical oncologist in ensuring that the best possible care is given to patients with cancer by actively participating in the whole spectrum of the patient's journey-from diagnosis, treatment, supportive care, until providing palliative care and addressing end-of-life issues.

What Will Keep Me Coming Back to the Clinic: Factors Identified by Filipino Colorectal Cancer Patients Seen at a National Academic Referral Center.

Health-care decisions in the Philippines are widely affected by various factors such as family, community, health-care access, and educational attainment. We designed a questionnaire to evaluate patient views at the University of the Philippines-Philippine General Hospital colorectal multidisciplinary clinic to identify factors that contribute to continued follow-up at the colorectal multidisciplinary clinic. A total of 128 patients, 62% of whom were being treated with curative intent participated in the study. We found that trust in their physicians, presence of family support, and affordability of treatment were factors highly valued by patients consulting at the clinic.

Bevacizumab in metastatic small-bowel adenocarcinoma: A systematic review and meta-analysis.

Cancers of the small bowel could account for less than 5% of all gastrointestinal malignancies. Of these tumors, adenocarcinomas were the major histologic subtype and generally carried a poor prognosis. High expression of vascular epithelial growth factor (VEGF) could be seen in small bowel adenocarcinomas. A systematic review was conducted here to determine if bevacizumab, a recombinant humanized antibody against VEGF, could offer clinical benefit among patients with metastatic small bowel adenocarcinoma when combined with chemotherapy. A search for relevant published and unpublished studies was performed using PubMed, ScienceDirect, Google Scholar, the American Society of Clinical Oncology meetings library, ClinicalTrials.gov, and ISRCTN registry. Information on study design, methods, intervention, and outcomes were extracted from selected eligible studies. Methodological quality was then assessed using the Newcastle-Ottawa Scale. There was a significant improvement in mean overall survival with the addition of bevacizumab with chemotherapy versus chemotherapy alone. The use of bevacizumab with chemotherapy, likewise improved progression-free survival and objective response rate compared to chemotherapy alone. Continued use of bevacizumab beyond first progression also appeared to show benefit. The conduct of prospective controlled studies by consortia to offset the rarity of small bowel adenocarcinomas could further elucidate the efficacy of bevacizumab in the treatment of this disease.

Prognostic utility of baseline neutrophil-to-lymphocyte ratio in patients receiving immune checkpoint inhibitors: a review and meta-analysis.

INTRODUCTION: Systemic inflammation is associated with prognosis in solid tumors. The neutrophil-to-lymphocyte ratio (NLR) is a marker for the general immune response to various stress stimuli. Studies have shown correlation of NLR to outcomes in immune checkpoint blockade, peripheral neutrophil count to intratumor neutrophil population, and NLR to intratumoral levels of myeloid-derived suppressor cells. Studies have shown elevated peripheral blood regulator T cells accompanied by elevated NLR are associated with poor outcomes further highlighting the importance of inflammation in the prognosis of cancer patients. METHODS: We performed a meta-analysis of published articles on the utility of baseline NLR in predicting outcomes in patients treated with immune checkpoint inhibitors (ICIs) using Review Manager, version 5.3. Seven studies on the prognostic utility of NLR in ICI treatment were included in this analysis. For outcomes of interest, the hazard ratios (HRs) were computed. Subgroup analyses were planned based on type of malignancy and type of immune checkpoint inhibitor. RESULTS/DISCUSSION: A high NLR resulted in worse overall survival (OS) (HR, 1.92; 95% CI, 1.29-2.87; p=0.001) and progression-free survival (PFS; HR, 1.66; 95% CI, 1.38-2.01; p<0.00001) across types of malignancies studied (melanoma, non-small-cell lung cancer, and genitourinary cancer). Subgroup analysis across different types of malignancies treated with ICI showed similar results for OS and PFS. The single study on genitourinary cancers also showed worse OS and PFS (OS: HR, 1.82; 95% CI, 1.29-2.87; p=0.001 and PFS: HR, 1.83; 95% CI, 0.97-3.44; p=0.06). A high NLR also showed worse OS and PFS across all ICIs (ipilimumab, nivolumab, and unspecified or pooled pembrolizumab and nivolumab; OS: HR, 1.92; 95% CI, 1.29-2.87; p=0.001 and PFS: HR, 1.66; 95% CI, 1.38-2.01; p<0.00001). Subgroup analysis by type of ICI showed similar results. CONCLUSION: A high NLR is associated with poorer outcomes across studies. This shows that NLR has the potential as a readily available prognostic indicator for patients receiving ICI based on available studies. Studies utilizing more stringent design may serve to better determine the utility of this tool.
