According to World Health Organisation (WHO), cervical cancer is the second most common cancer globally and the leading cause of cancer deaths among women [1]. In 2018 alone, about 510,000 women and 311,000 women were diagnosed with cervical cancer and died from the disease respectively [2]. Low and middle-income countries (LMICs) are disproportionately affected by the disease, with approximately 90% of the deaths occurring in LMICs [3, 4].
In south-eastern Africa, Malawi has the highest age-standardized incidence rate for cervical cancer, estimated at 72.9 cases per 100,000 women [5]. Among several studies conducted in Malawi, cervical cancer is the most commonly diagnosed cancer, accounting for 50% of all cancers [6–9]. Cervical cancer mortality in Malawi is also the highest globally, estimated at 49.8 per 100,000 women [4]. The high mortality of the disease, most commonly associated with late diagnosis, was highlighted in a recent study at Queen Elizabeth Central Hospital where 56% of patients were diagnosed with advanced-stage cancer during their first screening visit [10]. Reasons for late diagnosis and poor survival have been attributed to poor linkage to care for cervical cancer suspects, shortage of staff, lack of essential equipment and supplies, lack of supervision, and the use of male service providers [11].
Studies have shown that cervical cancer mortality can be achieved by timely and appropriate screening, treatment, and follow-up of eligible women [5, 8, 10, 12]. As a prevention strategy, cervical cancer screening with same-day treatment for pre-malignant lesions helps to improve the uptake of screening, ensures early case detection and treatment, and provides an opportunity for long-term follow-up. For LMICs, visual inspection of the cervix using acetic acid (VIA) by trained healthcare providers, followed by same-day treatment with cryotherapy or thermo-coagulation has been a cost-effective strategy for cervical cancer prevention [13]. Many studies have demonstrated improved case yield and good outcomes when using VIA and cryotherapy/thermo-coagulation as a secondary prevention method for cervical cancer [14–16].
Based on this screening strategy, Malawi has been implementing a cervical cancer control program using VIA and cryotherapy/thermo-coagulation for pre-malignant cervical lesions as a method of choice since 2004 [17–19]. In the current program, VIA and treatment for pre-malignant lesions have been provided as part of an integrated maternal and child health program, and sometimes within HIV and STI clinics, and cryotherapy or thermo-coagulation has been provided by the same provider. In many facilities, nurses who are the most common cadre of healthcare workers in Malawi provide these services [20].
Despite improvements in uptake of VIA and treatment with cryotherapy or thermo-coagulation in Malawi for pre-malignant lesions, lack of proper systems, referral pathways, and follow-up for women with VIA-positive lesions of more than 75% or women with lesions suspicious of cervical cancer (known as a large cervical lesion) remain a major challenge in Malawi [21]. Linking this group to appropriate follow-up and care is essential to reducing cervical cancer morbidity and mortality, as these women can be managed appropriately and timely [22, 23].
Several barriers to linkage to care for women with large cervical lesions after screening have been documented. Within the cervical cancer screening clinics both primary and secondary levels of care, women with large cervical lesions are referred for follow-up outside the clinics due to a lack of expertise in the management of these cases at the local level. Due to the lack of pathology services at the district hospital level in Malawi, women with large cervical lesions are often referred to tertiary hospitals for follow-up and management, a process that has been shown to delay the diagnosis of cervical cancer [24]. The delays are further worsened by the persistent staff shortages and lack of organized systems for identifying and tracking patients with large cervical lesions. More often, there is a communication breakdown between referring and referral facilities. As shown in other studies, there is a lack of community-based follow-up of women with large cervical lesions after the screening [25, 26]. Other community-level barriers to follow-up include lack of male partner involvement, long distances to referral facilities, lack of knowledge on cervical cancer and screening services, misperceptions about susceptibility to cervical cancer, and benefits of screening [12, 27, 28]. The COVID-19 pandemic has exacerbated the problem as governments in approximately 42% of countries worldwide completely or partially suspended cervical cancer screening services during the first wave of the pandemic [29].
Challenges with linkage to care for women with large cervical lesions after the screening were common in our setting in Neno district, a rural district in southern Malawi. Despite the ready availability of VIA and treatment with cryotherapy or thermo-coagulation, large gaps existed in the management of women with large cervical lesions after the screening. Before 2019, no follow-up data existed on patients diagnosed with large cervical lesions after the screening. No facility or community-level system to ensure follow-up of patients with large cervical lesions existed before 2019. For example, we did not know where patients were referred to after being diagnosed with a large cervical lesion, whether appropriate healthcare workers saw patients to determine the next treatment steps, whether these patients had cervical cancer biopsy taken, whether the patients received a proper diagnosis and whether patients were appropriately followed up.
In this paper, we describe a multidisciplinary cervical cancer tumor board aimed at improving the linkage and optimization of care for women diagnosed with large cervical lesions after the screening. Tumor boards (CCTBs) have been identified as key interventions to improve the care processes for clients with various cancers including cancer of the cervix [27, 28]. A tumor board is described as a committee of key staff members conducting case reviews and deciding on challenging cancer cases to determine the best care options for clients [27]. Some studies have demonstrated that CCTBs could improve the quality of life for cancer patients and those with lesions suspicious of cancer through notable improvements in retention and resulting in improved linkages to care pathways [17, 28, 30, 31]. After describing the role of the tumor board, we will proceed to describe a cohort of women with a large cervical lesion that was followed up between February 1, 2019, and April 30, 2021. Specifically, we will describe the proportion of women with a large cervical lesion who were enrolled in the CCTB and underwent cervical biopsy. Patients who had a biopsy taken will describe the turnaround time for biopsies, diagnoses after biopsy, the treatment, follow-up, and clinical outcomes. To our knowledge, this is the first rural district in Malawi to address challenges with linkage to care and follow-up among women with large cervical lesions after cervical cancer screening.
