Mortality Audit of Cancer Patients in the Department of Medical Oncology at a Tertiary Cancer Care Centre in South India.

Considerable advances in the diagnosis and treatment of cancer have made a huge impact on morbidity and mortality from neoplastic diseases. However, cancer remains the leading cause of death across the world. This is a retrospective study carried out at a tertiary cancer care centre (Kidwai Memorial Institute of Oncology, Bangalore) in South India. Case records of all cancer patients who died while receiving inpatient treatment between January 2022 and December 2022 under the Department of Medical Oncology were reviewed and studied. There was a total of 240 deaths. Out of these, the majority of deaths 147 (61.25%) were patients with haematological malignancies while the remaining 93 (38.75%) were patients with solid tumours. In patients with solid tumours, the majority 49 (52.7%) were in the age group of 40 to 60 years while only 18 (19.35%) patients were less than 40 years. The majority of patients were male sex i.e. 55(59.1%) and undergoing treatment with palliative intent 81 (87%). The most common organ was the lung in 21 patients (22.6%) followed by the breast while the most common system involved was the gastrointestinal tract in 28 (30.1%) patients. The most frequent cause of death was progressive disease in 72 (77.4%) while sepsis (11 patients; 11.8%) was the second most frequent cause of death in solid tumours. In haematological malignancies, also a significant number of 57 (38.8%) patients were in the age group of 40 to 60 years. Fifty-two (35.3%) patients were in the age group of 22 to 40 years. The majority were male sex (79 patients; 53.7%). About the phase of treatment, the majority of deaths 45 (30.6%) were during induction and under evaluation. Those with relapse/refractory disease were 38 (25.9%). A substantial number of patients had acute myeloid leukaemia 47 (32%) and five (3.4%) deaths were acute promyelocytic leukaemia patients. Twenty-three patients (15.6%) had acute lymphoblastic leukaemia. The most common cause of death was sepsis in 76 patients (51.7%) while intracranial bleeding was in 34 patients (23.1%). In some patients, there were multiple causes leading to death. Mortality audits are important to evaluate the services being provided at any centre. One can appreciate the lacunae in handling a particular disease or flaws in a treatment protocol or the staff delivering the treatment. Sepsis is the leading cause of death in patients with haematological malignancy; even in solid malignancy sepsis accounts for a substantial proportion of deaths and should be handled aggressively to save lives.
