Cancer-Related Stigma in Malawi: Narratives of Cancer Survivors

PURPOSE

Stigma is an impediment across the cancer care continuum, leading to delayed presentation to care, elevated morbidity and mortality, and reduced quality of life. The goal of this study was to qualitatively examine the drivers, manifestations, and impacts of cancer-related stigma among individuals who received cancer treatment in Malawi, and to identify opportunities to address stigma.

METHODS

Individuals who had completed treatment for lymphoma (n = 20) or breast cancer (n = 9) were recruited from observational cancer cohorts in Lilongwe, Malawi. Interviews explored the individual's cancer journey, from first symptoms through diagnosis, treatment, and recovery. Interviews were audio-recorded and translated from Chichewa to English. Data were coded for content related to stigma, and thematically analyzed to describe the drivers, manifestations, and impacts of stigma along the cancer journey.

RESULTS

Drivers of cancer stigma included beliefs of cancer origin (cancer as infectious; cancer as a marker of HIV; cancer due to bewitchment), perceived changes in the individual with cancer (loss of social/economic role; physical changes), and expectations about the individual's future (cancer as death sentence). Cancer stigma manifested through gossip, isolation, and courtesy stigma toward family members. The impacts of cancer stigma included mental health distress, impediments to care engagement, lack of cancer disclosure, and self-isolation. Participants suggested the following programmatic needs: community education about cancer; counseling in health facilities; and peer support from cancer survivors.

CONCLUSION

The results highlight multifactorial drivers, manifestations, and impacts of cancer-related stigma in Malawi, which may affect success of cancer screening and treatment programs. There is a clear need for multilevel interventions to improve community attitudes toward people with cancer, and to support individuals along the continuum of cancer care.

Kaposi Sarcoma, a Trifecta of Pathogenic Mechanisms

Kaposi's sarcoma is a rare disease with four known variants: classic, epidemic, endemic and iatrogenic (transplant-related), all caused by an oncogenic virus named Human Herpes Virus 8. The viral infection in itself, along with the oncogenic properties of HHV8 and with immune system dysfunction, forms the grounds on which Kaposi's Sarcoma may develop. Infection with HHV8 occurs through saliva via close contacts, blood, blood products, solid organ donation and, rarely, vertical transmission. Chronic inflammation and oncogenesis are promoted by a mix of viral genes that directly promote cell survival and transformation or interfere with the regular cell cycle and cell signaling (of particular note: LANA-1, v-IL6, vBCL-2, vIAP, vIRF3, vGPCR, gB, K1, K8.1, K15). The most common development sites for Kaposi's sarcoma are the skin, mucocutaneous zones, lymph nodes and visceral organs, but it can also rarely appear in the musculoskeletal system, urinary system, endocrine organs, heart or eye. Histopathologically, spindle cell proliferation with slit-like vascular spaces, plasma cell and lymphocyte infiltrate are characteristic. The clinical presentation is heterogenic depending on the variant; some patients have indolent disease and others have aggressive disease. The treatment options include highly active antiretroviral therapy, surgery, radiation therapy, chemotherapy, and immunotherapy. A literature search was carried out using the MEDLINE/PubMed, SCOPUS and Google Scholar databases with a combination of keywords with the aim to provide critical, concise, and comprehensive insights into advances in the pathogenic mechanism of Kaposi's sarcoma.
