Achieving health equity in cancer care in the Philippines.

Notwithstanding the progress made across the cancer care continuum, a major problem that many patients with cancer experience is the difficulty of access to global standards of care. Awareness of this problem has been increasing most especially when the economic context of a country forces health systems to deliver quality care despite the rising costs of diagnostic and therapeutic innovations amidst limited resources. Ultimately, inappropriate delivery of care to patients with cancer contributes to inadequate and unequal access to high-value therapy increasing financial toxicity among patients. This paper aims to highlight (1) the economic burden of cancer in the Philippines, (2) the saliency of identifying low-value interventions which come in two forms: the persistent over usage of proven ineffective modalities, and the underusage of potentially effective ones, and (3) the adverse effects of a decentralized health care system. The paper will also provide suggestions to address the challenges of achieving health equity in cancer care.

Geographic Distribution of Cancer Care Providers in the Philippines.

PURPOSE: In the Philippines, a lower middle-income country in Southeast Asia, 6 of 10 Filipinos die without seeing a doctor. To ensure universal access to cancer care, providers must be equitably distributed. Therefore, we evaluated the distribution of oncologists across all 17 regions in the Philippines. METHODS: We gathered data from the official websites of national medical societies on their members' regional area of practice: Philippine Society of Medical Oncology, Philippine Radiation Oncology Society, Surgical Oncology Society of the Philippines, Society of Gynecologic Oncologists of the Philippines, and Philippine Society of Hospice and Palliative Medicine. We compared this with the regional census to determine the number of board-certified oncologists per 100,000 Filipinos. RESULTS: For a population of almost 110 million, the Philippines has a total of 348 medical oncologists, 164 surgical oncologists, 99 radiation oncologists, 142 gynecologic oncologists, and 35 hospice and palliative medicine (HPM) specialists. This translates to 0.32 medical oncologists, 0.15 surgical oncologists, 0.09 radiation oncologists, 0.13 gynecologic oncologists, and 0.03 HPM specialists for every 100,000 Filipinos. The number of oncologists is highest in the National Capital Region in Luzon and lowest in the Bangsamoro Autonomous Region in Muslim Mindanao. All regions have at least one medical and gynecologic oncologist. Two regions (12%) have no surgical oncologists, five regions (29%) have no radiation oncologists, and eight regions (47%) have no HPM specialists. CONCLUSION: Efforts are needed to increase the number of oncologists and improve equity in their distribution to ensure universal access to cancer care in the Philippines.

Choosing Wisely Philippines: ten low-value or harmful practices that should be avoided in cancer care.

The Choosing Wisely Philippines campaign is an initiative that identifies low-value or potentially harmful practices that are relevant to patients with cancer in the Philippines. The main purpose of these initiatives is to facilitate quality improvement systems and maximise patient outcomes. Of the ten practices identified, four are new recommendations, and six are modified adaptations from previous Choosing Wisely initiatives in the USA and Africa. Recommendations in the final list include interventions involving diagnosis (two practices), treatment (five practices), palliative and supportive care (two practices) and surveillance (1 practice).

Cancer clinical trials in the Philippines.

In this Commentary, we discuss disparities in resources for and access to cancer trials from the perspective of the Philippines, a lower-middle-income country in Southeast Asia, where cancer is the fourth leading cause of death. Geographic disparities play out such that academic institutions and clinical trials are centralized in the island of Luzon, particularly in the capital, Manila. These disparities are compounded by the lack of comprehensive cancer patient and clinical trial registries in the Philippines. Additionally, sociocultural considerations influence clinical trial implementation. Providers must consider the role of a patient's family in the decision to participate in clinical trials; a patient's degree of health literacy; and the economic burden of cancer care, with attention to both the direct and indirect financial toxicities associated with cancer care. Our call to action is threefold. (1) Bolster locally led trials and encourage international collaboration to improve diversity in trial participation and trials' generalizability. (2) Strengthen national trial registries to improve awareness of trials for which patients are eligible. (3) Integrate cultural competency frameworks that move beyond parachutism and parasitism in research and instead promote trust, reciprocity, and collaboration. These challenges may yet evolve, but in emphasizing these barriers, we hope to kindle further dialogue, new insights, and innovative action towards solving these disparities in cancer research, not just in the Philippines, but also in other low- and middle-income countries.

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.

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.

High Content Analysis of Macrophage-Targeting EhPIb-Compounds against Cutaneous and Visceral Leishmania Species.

An immunostimulatory glycolipid molecule from the intestinal protozoan parasite Entamoeba histolytica (Eh) and its synthetic analogs derived from its phosphatidylinositol-b-anchor (EhPIb) previously showed considerable immunotherapeutic effects against Leishmania major infection in vitro and in vivo. Here, we describe a high content screening assay, based on primary murine macrophages. Parasites detection is based on a 90 kDA heat shock protein-specific staining, enabling the detection of several Leishmania species. We validated the assay using L. major, L. braziliensis, L. donovani, and L. infantum as well as investigated the anti-leishmanial activity of six immunostimulatory EhPIb-compounds (Eh-1 to Eh-6). Macrophages infected with dermotropic species were more sensitive towards treatment with the compounds as their viability showed a stronger reduction compared to macrophages infected with viscerotropic species. Most compounds caused a significant reduction of the infection rates and the parasite burdens depending on the infecting species. Only compound Eh-6 was found to have activity against all Leishmania species. Considering the challenges in anti-leishmanial drug discovery, we developed a multi-species screening assay capable of utilizing non-recombinant parasite strains, and demonstrated its usefulness by screening macrophage-targeting EhPIb-compounds showing their potential for the treatment of cutaneous and visceral leishmaniasis.

The Last Request.

This essay is a personal reflection highlighting the importance of spirituality in the care of cancer patients and their families especially at the end-of-life.

Beyond bevacizumab: a review of targeted agents in metastatic small bowel adenocarcinoma.

Small bowel cancers are rare tumors with an incidence 50-100-fold less than colorectal cancer. These tumors carry a poor prognosis. Owing to its rarity, treatment of this disease, particularly in its advanced stages, has not been optimized and is derived mainly from treatment regimens for colorectal cancer. Based on recent studies bevacizumab, an antibody directed against vascular endothelial growth factor and used in the management of metastatic CRC, has been added to treatment guidelines for metastatic small bowel adenocarcinoma. We investigate in this review the evidence behind other targeted treatments that may be beneficial in the treatment of metastatic small bowel adenocarcinoma. These are agents against EGFR, VEGFR-2, HER2, and NTRK as well as immune checkpoint inhibitors. The last class of drugs appears to hold the greatest promise based on the preponderance of evidence supporting its use. However, overall data remains sparse. Results of studies currently underway will be valuable in shedding more light on the management of this aggressive cancer.

Updated general recommendations in cancer management during the COVID-19 pandemic in the Philippines.

In May 2020, the Philippine Society of Medical Oncology published its initial recommendations on the treatment of cancer patients during the SARS-Cov-2 pandemic. The objective of this update is to provide answers to the questions pertaining to the diagnostic testing of SARS-CoV-2 for both cancer patients and healthcare professionals caring for cancer patients, as well as the recommended protective measures and practices that may be instituted in healthcare facilities.

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.

COVID-19 in cancer patients can be challenging to screen in a resource limited setting.

During this COVID-19 pandemic, patients with symptoms such as fever, cough, sore throat, and coryza were advised to have RT-PCR testing for SARS-CoV-2 infection. We described here an elderly female with chronic lymphocytic leukemia, who presented with atypical symptoms that were not directly attributable to COVID-19. This patient was admitted to the non-COVID-19 ward for supportive care. Later, her chest x-ray revealed pneumonia that was confirmed to be COVID-19 by RT-PCR testing several days later. In resource-poor settings where molecular testing results suffered from delays or were altogether unavailable, the use of diagnostic imaging such as a chest x-ray could serve as a quick guide in the assessment and management of these patients especially if the imaging results suggest COVID-19 infection.

Treatment of cancer patients during the COVID-19 pandemic in the Philippines.

The COVID-19 pandemic has caused disruptions in cancer care around the world due to logistical and psychosocial reasons. This paper was written with the primary objective of providing a guide for medical oncologists in addressing concerns in the management of adult patients with solid tumours in the Philippines and for those working under similar circumstances. These recommendations are divided into prioritisation of cancer care, ensuring a safe work environment, organising the transition of cancer care, and maintaining cohesion in a time of isolation.

Antileishmanial Effects of Synthetic EhPIb Analogs Derived from the Entamoeba histolytica Lipopeptidephosphoglycan.

With an estimated number of new cases annually of approximately 1.4 million, leishmaniasis belongs to the most important parasitic diseases in the world. Nevertheless, existing drugs against leishmaniasis in general have several drawbacks that urgently necessitate new drug development. A glycolipid molecule of the intestinal protozoan parasite Entamoeba histolytica and its synthetic analogs previously showed considerable immunotherapeutic effects against Leishmania major infection. Here, we designed and synthesized a series of new immunostimulatory compounds derived from the phosphatidylinositol b anchor of Entamoeba histolytica (EhPIb) subunit of the native compound and investigated their antileishmanial activity in vitro and in vivo in a murine model of cutaneous leishmaniasis. The new synthetic EhPIb analogs showed almost no toxicity in vitro Treatment with the analogs significantly decreased the parasite load in murine and human macrophages in vitro In addition, topical application of the EhPIb analog Eh-1 significantly reduced cutaneous lesions in the murine model, correlating with an increase in the production of selected Th1 cytokines. In addition, we could show in in vitro experiments that treatment with Eh-1 led to a decrease in mRNA expression of arginase-1 (Arg1) and interleukin 4 (IL-4), which are required by the parasites to circumvent their elimination by the immune response. The use of the host-targeting synthetic EhPIb compounds, either alone or in combination therapy with antiparasitic drugs, shows promise for treating cutaneous leishmaniasis and therefore might improve the current unsatisfactory status of chemotherapy against this infectious disease.

Treatment Outcomes of Patients With Colorectal Cancer Enrolled in a Comprehensive Benefits Program of the National Insurance System in the Philippines: Data From the Pilot Site.

PURPOSE: Cancer treatment causes significant financial burden, especially in developing countries such as the Philippines. This led the Philippine Department of Health to create the Z-Package colorectal cancer benefit program, an insurance system specifically designed to treat Filipinos with colorectal cancers with early to locally advanced-stage disease. The main goal of this program is to optimize treatment outcomes for this curable disease without causing financial toxicity. MATERIALS AND METHODS: Three-year data on patients enrolled in the Z-Package colorectal cancer benefit program from 2016 to 2018 were reviewed by the University of the Philippines, Philippine General Hospital Colorectal Polyp and Cancer Study Group. RESULTS: A total of 251 patients were enrolled in the Z-package colorectal cancer benefit program from 2016 to 2018. Mean age was 57 years old and a majority of patients (66%) were male. A majority of patients had rectal cancer (78%) and were diagnosed with stage III disease (82%). A majority (75%) were compliant to their treatment plans and clinic follow-up. Specifically, compliance to the prescribed surgery, chemotherapy, and/or radiation treatment were 90%, 77%, and 96%, respectively. Recurrence, morbidity, and mortality rates of enrolled patients in the Z-Package program from 2016 to 2018 were 17%, 22%, and 19%, respectively. Morbidities were mostly chemotherapy related (8%). Finally, patients in this program had a 2- and 3-year survival probability of 74% and 70%, respectively, which are comparable with data from more developed nations. CONCLUSION: Results of this study include real-world data that show that when the highest standards of patient care are provided through a multidisciplinary team, patients' overall survival is also maximized.
